This is the first of four articles scheduled for publication in this journal on the position people with normal and abnormal personalities take in regard to so-called existential dichotomies. The main objective of this article is to propose a new, existential criterion for normal and abnormal personality implicitly present in the works of Erich Fromm. According to this criterion, normal and abnormal personalities are determined, first, by special features of the content of their position regarding existential dichotomies, and, second, by particular aspects of the formation of this position. Such dichotomies, entitatively existent in all human life, are inherent, two-alternative contradictions. The position of a normal personality in its content orients one toward a contradictious predetermination of life in the form of existential dichotomies and the necessity of searching for compromise in resolving these dichotomies. This position is created on a rational basis with the person’s active participation. The position of an abnormal personality in its content subjectively denies a contradictious predetermination of life in the form of existential dichotomies and orients one toward a consistent, noncompetitive, and, as a consequence, one-sided way of life that doesn’t include self-determination. This position is imposed by other people on an irrational basis. Abnormal personality interpreted like this is one of the most important factors influencing the development of various kinds of psychological problems and mental disorders — primarily, neurosis. In the following three articles it will be shown that this criterion is also implicitly present in the theories of personality devised by Sigmund Freud, Alfred Adler, Carl Jung, Carl Rogers, and Viktor Frankl.

This article studies the structure of the pastime of contemporary preschool children and the importance and prevalence of various kinds of activities that parents and their children share. The emphasis is on those features of parental behavior that are determined by gender role (mother/father), family status (two-parent/separated family), style of parentchild relationship, and also child’s gender. The work is based on data from 1,936 questionnaires received from parents of preschool children (from 1.5 to 7 years old) who were attending Moscow kindergartens. The research was carried out in 41 kindergartens in 9 districts of Moscow. The survey uncovered several social-psychological features of the position parents take while organizing their shared pastime with preschool children: the influence of traditional gender-role models of parental behavior; the “complementary” principle of mother’s and father’s social-role positions in the upbringing of a daughter; the distortion of traditional maternal behavior in the upbringing of a son in a separated family; the reduced organization of shared play with a child in a separated family; the influence of the style of the parent-child relationship on the participation of parents in their children’s activities. The dynamics show how the parents’ position changes as their children grow older (from 1.5 years to 7 years): namely, the decrease of parents’ organization of and participation in a preschool child’s activities has a negative impact on their emotional state while interacting with the child.

With regard to cultural-historical and activity approaches, collaborative activity with an adult, including communication as a type of meta-activity, is considered to be the necessary mechanism of child development. A child is considered to be an active partner, possessing his/her own motives, and is guided by mental representations of the parent and interactions with him/her. Russian psychologists have developed a range of parenting style classifications; however, these styles primarily emphasize a parent’s position, contrary to methodological perspectives, with inadequate consideration of a child’s own agency. The aims of the current research were to investigate actual goal-oriented interactions between preschoolers and their parents and to outline certain patterns (types) of interactions, considering both partners and analyzing interac- tions according to the activity model. A total of 75 parent-child dyads (children aged from 4.6 years to 6.11 years) participated in “collaborative activity trials” in which the observational method was based on the activity approach. Cluster analysis (k-means clusterization) revealed five different groups of parent-child dyads: conflictual, harmonious, distant and two-fold dominant (with dominant parent or dominant child). Between-group comparisons (Mann-Whitney U test) showed significant differences in a range of parameters of activity and emotional components of interactions. The harmonious type of interactions is not prevalent, although subgroups with different types of domination are the most common, which may be attributed to cultural peculiarities. Domination-subordination misbalance does not seem to seriously distort the normal developmental trajectory; however, in cases of conflictual and distant dyads, interactional issues might hinder the course of goal-oriented activity, which might serve as a predictor for potential difficulties in further learning.

Play and playfulness are basic features in early childhood education. The elements of play are pleasure, a sense of freedom, and the co-construction of shared meaning through the use of rules or rhythms. Play and learning are closely related in early childhood. But when the focus on the educational benefits of play becomes too strong, the most essential feature of play is lost: children’s pleasure. Young children in group settings often have to adapt to the teachers’ demands related to security, hygiene, and social norms and values. But the playfulness of the teachers helps to overcome differences in power in the caregiver-child relationship and prevents young children from becoming overburdened with strict rules and group discipline. Play and playfulness are a resource of shared pleasure and creativity in learning processes.

Learning through play is a common phrase in early childhood education worldwide. Play is often put forward as the overarching principle for working with young children (Johnson, Christie, & Wardle, 2005). However, if we go beyond the rhetorical level and explore how “learning through play” and a “play-based curriculum” are understood and transformed into practice, we may find differences both within and between countries (Karlsson Lohmander & Pramling Samuelsson, 2014a, 2014b; Pramling Samuelsson & Fleer, 2009).

In this article we discuss the relationship between the concepts of play and learning and describe how they are enacted in everyday practice in early childhood education in Sweden. Starting with a brief presentation of the development of early childhood education, we then reflect on the challenges preschool teachers may encounter when trying to implement a new learning-oriented curriculum (National Agency for Education, 2011) and still trying to keep play as a central dimension in children’s everyday life in preschool.

Since the turn of the century, politicians in the Scandinavian countries have placed great emphasis on early childhood education and care. They have been especially concerned with lifelong learning in the field of language learning, early literacy, and numeracy. Almost all children between the ages of 1 and 6 years attend a preschool, and the quality of the learning environment is of great importance. This article presents a comparative study of student preschool teachers’ conceptions of the knowledge that they claim to have acquired about children’s early literacy throughout their bachelor education in Norway and in Sweden. The aim is to compare responses to a questionnaire administered to the student teachers and to examine the similarities and differences in the content of and goals indicated in the two countries’ national plans for early literacy. This study is based on sociocultural theories and has a multimethod design. First, through a discourse analysis we examined the national plans for preschool teacher education in Norway and Sweden and studied similarities and differences. Second, we sent a questionnaire to all student preschool teachers at all universities and university colleges in Norway and at the University of Gothenburg. The differences between the Norwegian and Swedish education students were most obviously seen in their responses to the questions about how they work with early literacy. The discourse analyses showed that the national education plans for preschool teacher education in the two countries differ in certain instances but share common ground in others.

The current issue of Psychology in Russia: State of the Art opens with reports from the 4th Annual international research-to-practice conference “Early Childhood Care and Education” held on April 23rd - 25th 2015 at the Lomonosov Moscow State University (Moscow, Russia).

Considering today’s abundance of psychology books, from reprints of timeless classic works through scholarly editions to popular literature, it is hard to expect a new book to become a big event in psychology. However, a book entitled The Phenomenon of Envy is hard to overlook: as observed by the author, very few people are unaffected by envy. Besides, the name of the author, Aleksander I. Dontsov, former head of the Faculty of Psychology at Moscow State University and of the Russian Psychological Society, is well known among Russian scholars.

This study was developed because vandal behavior is an increasing threat in the world. Countries, commercial companies, and individuals experience great damage to property as a result of individual vandal acts. In addition, vandalism threatens not only “tangible assets” but also the cultural and historical heritage of modern humanity. Despite the threatening spread of vandalism, the study of its psychological foundations, including its origins, in the context of individual life courses is in many ways terra incognita. The objective of the present study was to investigate the genesis of vandal behavior and the sociopsychological and individual personality factors in the formation of readiness to destroy public property and the property of others. A comprehensive study of children, adolescents, and young adults (N=1522), as well as of their social environment, revealed mechanisms of the readiness to commit vandal acts that were present since childhood. The study was conducted by examining four age groups: preschoolers (4–6 years), primary school pupils (7–9 years), adolescents (12–15 years), and young adults (17–22 years); the instruments used were specific-age batteries, observation, expert techniques, and questionnaires. We found that the characteristics of parent-child relationship are is the basis for forming the boundaries of the permissible activity of the child; disturbance in the parent-child relationship can lead to the development of forms of vandalism in children. We describe the specificity and intensity of the vandal activity of adolescents and young adults in the context of their environment, and we look at the individual characteristics that promote deviant behavior. Thus, vandal activity is not only a specific characteristic of adolescents and young adults, and it is not always very destructive. Basic vandal activity originates in the early stages of ontogenesis as a result of a deformation in social interaction that becomes fixed and converted into the destructive actions of people trying through this form of activity to understand themselves in social space.

This article presents the results of a theoretical and methodological analysis and empirical study of semantic formations in the structure of a world image as factors in teenagers’ self-destructive behavior in contemporary Russian society. During the teenage years the value-semantic bases of a world image are being formed. A world image is the integral, multilevel representation of the subject, which consists of social reality and himself/herself; it exists in the mind as a unity of sensual fabrications, significations, and personalized meanings. Transformations of semantic components of a world image that are inadequate for the environment or that are externally and internally rigid can serve as preconditions for disadaptation and for one of its extreme forms—self-destructive behavior. The purpose of our empirical research was to determine the main characteristics of basic conceptual formations in the structure of a world image—that is, attitudes, intentions, motives, and values— that serve as predictors of disadaptation in modern teenagers. The teenagers in the study were born in different generations with a ten-year interval (1990–1991 and 2000–2001). Our empirical research of the semantic world-image structures that serve as bases for the self-destructive behavior of modern teenagers consisted of two phases. The first phase provided a comparative analysis of the relationships, value preferences, and basic conceptual intentions that raise the possibility of disadaptation and self-destructive behavior among teenagers. In order to perform this analysis, we analyzed data from the Character-Pathological Diagnostic Poll (PDP) of A. E. Lichko. During the second phase, a comparative analysis was carried out of the basic semantic components of teenagers’ images of the world and self-destructive and normative behavior. The main conceptual world-image structures were defined with the help of projective methods: the Thematic Apperception Test (TAT) and the modification for teenagers and youth (TAT-Y), which was developed by A. N. Alekhin and others. The main changes in the value-semantic orientations and personality dispositions of Russian teenagers in the late 20th to early 21st centuries were defined. The features of the semantic organization of these teenagers’ world image as a precondition for disadaptive behavior were uncovered, and the personality preconditions for their self-destructive behavior were identified: their world image is fragmentary and self-contradictory; their personality features include cognitive distortions, a negative emotional state, ambivalence of motives and disposition, and disharmony with world-image semantic structures. The indicator for social disadaptation and behavioral deviation in modern Russian teenagers is evident deformation of personal relationships as the basic cognitive structure of their world image.

The study of personal qualities’ development and the peculiarities of value-motivational aspects in groups with various manifestation levels of these qualities are of particular interest for contemporary researchers as well as for practicing psychologists who develop psychotechnologies aimed at personal value-motivational sphere management.This article suggests new approaches for analyzing and studying value-motivational aspects of personal activity, predetermining innovation activity. It also provides an analysis of a comparative empirical study that evolves value-motivational characteristics in students with various innovativeness levels.

The author submits a detailed theoretical analysis of innovation behavior based on manifestations of personal value-motivational activity. Resulting from the given theoretical analysis, a suggestion is made that the manifestation and development of personal potential is determined by values and motives. Personal innovation potential is regarded as an effective combination of various activity forms, and innovativeness is a personal quality that is manifested by a form of effective activity. Currently, psychologists are highly interested in evolving value-motivational structure of personal innovativeness.

The given article discusses the results of an empirical study aimed at revealing value- motivational peculiarities of students in groups with various levels of innovativeness manifestations. Indicative peculiarities of value-motivational characteristics are revealed in groups with low, middle and high levels of innovative qualities. Furthermore, gender differences in innovativeness manifestation and value-motivational characteristics of this quality in young men and women are thoroughly described.

New data concerning the personal and gender specifics of the value-motivational sphere and innovativeness manifestation in young adults are presented using a thoroughly described research strategy as well as results substantiation.

Television has a strong impact on gender-identity development. Theoretical analysis shows that the direct perception of different gender characteristics in advertising images has a specific impact on gender self-consciousness, primarily at the unconscious level. The purpose of our study was to uncover features of this impact.

In this study, the effects of advertising images on the gender self-consciousness of teenagers were investigated. Two hypotheses were examined: (1) Perception of gender images in TV commercials has individual variability and is connected with gender features of self-consciousness (gender type of personality, gender differentiation of consciousness, the specifics of gender identification). (2) Direct perception of gender images in TV commercials has a differential influence on the transformation of verbal (cognitive) and nonverbal (emotive) levels of selfconsciousness.

The commercials, which were for chocolate, contained different gender types of male and female images (masculine female images, androgynous images, and feminine male images); they used as stimulus materials in an experimental situation involving 61 teenagers. The contents and dynamics of gender self-consciousness in adolescents were investigated using the psychosemantic method of “multiple identifications.”

We discovered that the girls’ preferences for gender images were more varied than those of the boys. Despite different variants in the gender characteristics in the advertising images, their impact on the gender self-consciousness of the adolescents consisted mostly of gender differentiation and identification with the images of their own gender. In general, in regard to the direct impact in the experimental situation, at the cognitive level, the girls revealed changes in the enhancement of gender identification with images of their gender, and the boys were characterized by the enhancement of gender differentiation. At the level of emotive evaluation, in contrast to the cognitive level, we observed stronger dynamics of the changes in selfconsciousness (enhancement of gender differentiation and enhancement of identification with images of ideals and parental images).

The results clearly showed the quite high plasticity of self-consciousness structures and their susceptibility to externally designated images. We concluded that, in their direct perception, features of gender images in TV commercials have specific effects on the consciousness of adolescents: they reinforce already-formed gender categories and self-identification. We consider this research a pilot study, and we are planning to check the results on a more representative sample with different age groups.

The interest of psychologists in the study of safety in the educational environment and its psychological characteristics is increasing. The aim of this study was to select, substantiate, and disclose the psychological factors in the educational environment that influence the psychological well-being of pupils. There were three stages in our research: clarifying the level of psychological safety in the schools in the study; revealing the consistency of the teachers’ and the students’ evaluations of the level of psychological safety in those schools; determining the nature of the influence of the psychological safety of the educational environment on the psychological well-being of the students. The study involved 172 teachers and 876 students in Moscow and St. Petersburg schools.

Psychological safety is a condition of educational environments that are free from psychological violence in the interactions of the people in them; psychological safety contributes to the satisfaction of the needs for personal trust and communication, creates for the participants a sense of belonging (the referential importance of the environment), and contributes to their mental health.

The empirical study revealed that (1) the level of the psychological safety of the educational environment in the evaluations of the teachers was higher and had more expressed differentiation than did the level in the students’ evaluations; (2) the psychological well-being of the students was closely correlated with the level of psychological safety for the teachers; (3) such components of the well-being of the students as emotional comfort, self-confidence, a higher level of cognitive activity were developed in those schools with high levels of psychological safety for the teachers.

The results can be useful in educational psychology and environmental psychology as well as when creating technologies to support the safety of school environments and of the people in them, including situations related to minimizing safety violations and reducing risks and threats.

The negative sociocultural transformations that are taking place in modern society and the resulting psychological transformation of personality and mode of life strongly require searching for ways of providing social safety to the next generation, with teachers being the implementers of this process. Teachers’ professionalism is determined by their willingness to solve personal and socially relevant problems, including the willingness to provide social security for other people, to thwart social risks, and to build constructive interpersonal relationships.

The aim of our research was to reveal and to analyze the psychological factors affecting the readiness of teachers to ensure social security in educational environments.

The environmental factors of social risk have been theoretically characterized. It has been shown that the essential factor in ensuring students’ social security is providing a safe social environment in educational institutions; such an environment provides the learners and the teachers with sociopsychological security and psychosocial well-being. The empirical part of our study was devoted to identifying negative social phenomena in the schools in the Ivanovo region (with the help of a questionnaire administered to 700 students) and to identifying the personally and professionally important qualities of the teachers and the subjective psychological factors of their readiness to ensure social security in the educational environment (through interviewing 300 teachers); the administration of the questionnaires and the interviewing were followed by an assessment of their significance (with the help of a questionnaire administered to 140 teachers). Using factor analysis we identified the relevant indicators and grouped them into six factors of the readiness of teachers to ensure a safe educational environment.

Relevant personal and professional qualities of teachers were revealed; these are the subjective factors of the readiness of a teacher to ensure social security in the educational environment: social anticipation, resistance to sociopsychological stress, social tolerance, professional orientation, responsibility, communication skills.

Data were collected in the analytical and experimental studies to determine ways to improve the organization of educational processes in order to ensure the social security of students and society in general. The identified psychological factors, their relative weight, and content must be considered when designing a system for training teachers and developing in them the required personal and professional qualities.

Years of social, economic, and political changes have resulted in intensive and extensive migration activity. The appearance of compelled and voluntary migrants has brought about the development of a new direction in social psychology: the psychology of migration. Many disciplines are connected with the study of migration, the problems of migrants, and adaptation processes. In the social-psychological literature, various models of adaptation to new conditions of a social-cultural environment are considered (I. Jasinskaja-Lahti, K. Liebkind, J. Berry; S.-K. Lee, J. Sobal, E. Frongillo). Various social-psychological features of migrants are studied: for example, ethnic identity, characteristics of psychological adaptation, emotional well-being, and mental health. In the Russian scientific literature the following problems are considered: emigrants’ interactions with representatives of foreign cultures (N. S. Khrustaleva), degree of cultural similarity (T.G. Stefanenko), personal features of emigrants (S. H. Schwartz, E. Prince-Gibson), features of ethnic identity (G.U. Soldatova, S. D. Gurieva), and many others. In Russia, research regarding the influence of the social-cultural environment on processes of adaptation were begun only in 2004.

The main objective of our study was to identify psychological mechanisms of migration flows (incoming and outgoing) as indicators of sociopolitical and psychological stability in the Pskov Region. Participants in the study were citizens permanently residing in the Pskov Region who by age and social characteristics represented the population structure of a part of that region. In total, 52 persons aged 17 to 69, with an average age of 42.3, participated.

The technique used was focus groups. A content analysis was made of the answers received in the focus-group sessions. During these sessions, participants could freely share their views on questions asked by the facilitators who had a college-level psychological education. In each group, two facilitators worked cooperatively. One facilitator was in charge of group dynamics; the other was in charge of asking all the questions covered as well as of keeping track of all the substantial aspects of the conversation. This arrangement encouraged the participants to discuss issues of the region in an open manner.

The findings allowed us to classify all the migrants and potential migrants in the Pskov Region according to their reasons and motives for migration. For example, in the Plyussa settlement, which is “depressed” and remote from the region’s center, migrants seek to escape their extreme poverty and unemployment; they can be called “survival migrants.” In the “favored” central area, the city of Pskov, migrants seek to significantly increase their income level and improve their quality of life. We can describe them as “migrants seeking new opportunities.” In a border area, the town of Gdov, people living in close proximity to other countries (Estonia, Latvia) compare their financial situation and opportunities with those of their foreign neighbors. Migrants living in Gdov tend to move because they want to avoid an environmental crisis or progressive degradation of the environment, structural unemployment, and poor economic opportunities. We can call them “migrants in search of hope and prosperity.”

In the Pskov Region, the labor (economic) situation is a typical reason for migration. Migration for economic reasons is a resettlement of people for the purpose of employment and proper remuneration. Labor migration can have such causes as a desire to change one’s job, as well as sociocultural, housing, environmental, nature, climate, and other conditions. Without a developed economy and social sphere, regions are able to prevent only elderly or incapacitated people from migrating. To retain the younger generation, it is necessary to inform people of all the possible difficulties that potential migrants may face and to make systematic and large-scale efforts to develop the region, to improve the image of the region (including encouraging the residents to be proud of and to cherish the region’s heritage and its people’s achievements), and to create a comfortable environment.

This article describes the theoretical difference between the flexibility and the multidimensionality of thinking. Multidimensionality is discussed as a characteristic of thinking that is necessary for exploration of the variability of structural transformations of problematic situations.

The objective of the study was to examine a number of theories concerning the correlative connection between the multidimensionality of thinking and other characteristics of creative, productive thinking: the flexibility of thinking; the formation of an operation of dialectical thinking such as “mediation”; the ability of a person to use a scheme as an abstraction for analysis of various specific content.

A total of 85 people participated in the study: they were 15 to 17 years old, students at a senior school in Kaliningradskaya oblast, winners of different stages of the all-Russian academic competition in physics, chemistry, and mathematics. All respondents had a high level of academic success and of general intelligence.

The following techniques were used in this study: (1) my technique for diagnostics of the multidimensionality of thinking; (2) my technique of “schemes and paintings,” designed for diagnostics of the ability to relate abstract schemes and various specific content; (3) the Torrance Tests of Creative Thinking (verbal battery); (4) a diagnostic technique for dialectical thinking: “What can be simultaneous?”

All the hypotheses were confirmed.

Confirmation was received of the existence of a correlation connection; this finding counts in favor of the assumption that the parameters of thinking my colleagues and I were working with can in aggregate be considered an integral characteristic of human thinking. It allows us to distinguish significant features of a situation from secondary ones—that is, to see a substantial contradiction and to propose several options for its transformation.

The objective of this research was to assess the motivational potential of psychology students using an egoskopiya method. Heart rate and EEG data were recorded while the participants performed the Mehrabian achievement motivation test. Thirty students of the Faculty of Psychology of Southern Federal University who were aged between 20 and 30 years participated. The psychodiagnostic study involved 136 students from the Faculty of Psychology of Southern Federal University who were aged between 18 and 49 years. To determine the lateral organization profiles of sensory and motor functions, a computer-based testing program termed “Profile” was used. The Compact Russian Structure of Temperament Questionnaire (STQ-77) was used to evaluate the features of temperament. 

The results revealed that people with a strong motivation to succeed exhibited a predominance of right features in their lateral organization profiles. Their cardiovascular systems were in more activated states than those of the people who were extremely motivated to avoid failure. The observed temperament features of psychology students with different levels of achievement motivation indicated that the level of achievement motivation is related to the properties of temperament such that students with lower levels of achievement motivation (i.e., motivation to avoid failure) exhibited the temperament traits of Neuroticism and Impulsivity in addition to low values on the scales for the Sensitivity to Sensations, Intellectual Ergonicity, and Sensitivity to Probabilities. High levels of achievement motivation (i.e., motivation to strive toward success) corresponded to the psychology students’ propensities for Sensitivity to Sensations, high levels of Intellectual Ergonicity, high levels of Sensitivity to Probabilities and low values on the scales of Impulsivity and Neuroticism.

The study aimed to investigate the basic aspects of quality of life and relation to disease in patients with malignant or premalignant bone tumors. Study participants (N=82) were aged 18 to 67 years (average age 34 ± 2 years). They were separated into three groups depending on diagnosis: patients with osteosarcoma, patients with giant cell tumor and patients with chondrosarcoma. The SF-36 Health Status Survey and the Quality of Life Questionnaire - Core 30 with Bone Metastasis (BM22) Module were used to assess patient quality of life. The type of relation to disease method (TOBOL) was used to determine the relation to disease of the patients.

According to the results of the quality of life study, patients with giant cell tumor exhibited the highest degree of limiting physical activity and reduced social functioning, the greatest financial difficulties and more pain sites than either patients with osteosarcoma or patients with chondrosarcoma. The study of relation to disease revealed that all studied groups of patients were susceptible to ergopathic and sensitive types of relation to disease. Moreover, patients with giant cell tumor experienced increased levels of tension and irritability with respect to relation to disease and treatment, while patients with chondrosarcoma were more susceptible to anxiety and hypochondria with respect to relation to disease.

Patients with different types of bone tumors have different experiences with respect to their physical and mental health, their social functioning and their general health. The results of the study may be useful in developing individualized psychological aid programs for patients with malignant and premalignant bone tumors.

An in vitro fertilization (IVF) pregnancy is stressful both financially and emotionally. Patients undergoing an IVF procedure often have already had infertility and reproductive losses. Pregnancy through IVF involves the increased risk of various medical complications. Experts around the world are actively engaged in studying the specifics of the mental state of participants in IVF programs during pregnancy. Of critical importance is the issue of providing psychological support for couples who are preparing for and who have received an IVF pregnancy. 

The aim of our research was to investigate the mental state of women participating in an IVF program. The study involved 224 pregnant women in the second and third trimesters: 62 women with an IVF pregnancy and 162 women who conceived naturally. The study took place at the Kulakov Scientific Center for Obstetrics, Gynecology, and Perinatology in Moscow, Russia. All the study participants had encountered medical complications during their pregnancy. No significant differences were identified in mental well-being in the two groups; this finding suggests that somatic complications during pregnancy are a general source of anxiety regardless of the reason for their occurrence. The second and third trimesters of pregnancy register increased anxiety levels associated with experiences of reproductive loss and the presence of physical problems. The main resources of a woman’s personality that contribute to her self-confidence and mental stability are her professional employment and flexible behavior.

A major risk factor for late-onset Alzheimer’s type dementia (DAT) is the carriage of the ε4 allele of the apolipoprotein E (ApoE) gene. Identifying cognitive deficits in healthy ApoE-ε4 carriers is valuable in order to develop interventions to prevent them from developing DAT. Existing evidence about cognitive deficits in the domains of episodic memory and cognitive control specific to ApoE-ε4 is contradictory.

The objective of our research was to assess episodic memory and cognitive control in healthy ApoE-ε4 carriers.

Cognitively healthy ApoE-ε4 carriers (13 ε4/ε4 heterozygotes) and noncarriers (22 ε3/ε3 homozygotes), who were matched on age and family history of DAT, were compared on episodic-memory and cognitive-control tasks. Episodic-memory tasks were verbal and visual recognition tasks with a systematic variation of distractor-to-target similarity. Executive functions were assessed by a task for updating working memory, an inhibition task, and a switching task. Working-memory capacity was also assessed.

The results showed that executive functions were generally not impaired in the carriers, but carriers showed a specific increase in accuracy-related switch costs. Workingmemory capacity was not reduced in the carriers. In the domain of episodic memory, the carriers were found to make more errors with phonetic distractors in the verbal episodicmemory task. They also tended to make more errors with visually dissimilar distractors in the visual episodic-memory task.

The results are indicative of an episodic-memory deficit specific to the carriage of ApoE-ε4. This deficit may be driven either by deficits in storage or by deficits in the encoding of the to-be-remembered material. Contradictory results concerning the presence of an episodic-memory deficit obtained in previous studies may stem from small effect sizes, the use of specific materials, and the employment of attention-intensive encoding strategies. The carriers also showed a switching deficit that possibly is related to difficulty in retrieving task rules from episodic memory. Existing empirical contradictions concerning the presence of an executive deficit in carriers may in part depend on the extent to which tasks used to assess an executive deficit draw on the switching function. In this study, there was no general executive deficit in the carriers of ApoE-ε4.
