Background. Despite the global tendency toward multidisciplinary research, there is still an abysm between some areas of human science. For example, in the motor control area, psychology should contribute to a better comprehension of human movement, and vice versa, the motor control in the psychological branch should also be considered more. Comparative studies on individual and personality differences in the representatives of various cultures are less biased if studied with the use of motor control or graphical methods because these methods do not require any linguistic or cultural adaptation.

Objective & Methods. In this study, which aims to observe the individual characteristics of the participants (170 in total) from different cultures (by countries of birth and residence), we used the graphomotor method, the Proprioceptive Diagnostics of Temperament and Character (Tous et al, 2012) that evolved within the traditional Miokinetical Psychodiagnosis of Mira y Lopez (1958). 

Design. Individual cultural differences (participants by origin or residence from Spain, Morocco, East Europe and Latin America) in graphical test performance (fine motor precision) were measured in the proprioceptive sensory condition (without visual guidance) for both hands (dominant and non-dominant) in three movement types (Frontal, Transversal and Sagittal). Sex differences were also observed and discussed. The related psychological meaning of these individual differences are also discussed.

Results. The results of this study are discussed in the article. They included not only the description of the specific test conditions (hand use, movement, and bias types) but also the explanation of the psychological meaning of differences (personality dimensions) compared with the cultural groups or sex subgroups levels. Moreover, the differences between men and women within each cultural subgroup are also analyzed. Better comprehension of cultural differences would help to obtain more qualified therapeutic, educational and judicial help, by reducing of the derived possible negative biases or misinterpretations in human behavior. This can result in such benefits, for example, as better adaptation of immigrants in other cultures.

Conclusion. The majority of significant differences between representatives of various cultural subgroups in this study were obtained in the non-dominant hand meaning that such differences were more at the basis level. Further adaptive behavior to the environmental changes in their lives led to disappearance of such differences, especially in those who were residing in the same country.

Background. Embodied finger counting has been shown to have cross-cultural differences in previous studies (Lindemann, Alipour, & Fisher, 2011; Soto & Lalain, 2008). However, their results were contradictory in reference to Western populations with regard to the hand preferred: The first study showed that in Western countries — Europe and the United States — participants preferred to start with the left hand (whereas in the Middle East — Iran — they used the right hand); the second study showed that participants in France preferred the right hand.

Objective. Our study aimed to observe these differences in two countries, Spain (Western Europe) and Russia (Eastern Europe part), although taking into account the variety of cultural or ethnic groups who live there.

Design. The observational/descriptive study, together with correlational analysis of the finger-counting pattern (from 1 to 10) used by children aged 10 to 12 who had not been taught to use their fingers for counting, considered factors of cultural origin and hand dominance. The possible effects of this action on cognition — in our case, math achievement — were considered also.

Results and conclusion. The differences in the frequency of the finger-counting patterns might suggest cultural-individual differences in performance; however, the correlational analysis did not reveal that these differences were statistically significant, either for gender or for mark in math. However, hand dominance was a significant predictor of the preferred hand with which to start counting.

Human error is commonly differentiated into three different types. These are: errors in perception, errors in decision and errors in sensation. This analysis is based on classical psychophysics (Fechner, 1860) and describes the errors of detection and perception. Decision- making errors are evaluated in terms of the theory of signal detection (McNicholson, 1974), and errors of sensation or sensitivity are evaluated in terms of proprioceptive information (van Beers, 2001).

Each of these stages developed its own method of evaluation that has influenced the development of ergonomics in the event of errors in perception and the verbal assessment of personality (stress, impulsiveness, burnout, etc.) in decision-making errors. Here we represent the method we have developed, the Proprioceptive Diagnosis of Temperament and Character (DP- TC) test, for the specific assessment of errors of perception or expressivity which are based on fine motor precision performance.

Each of the described errors types are interdependent of each other in such a manner that observable stress in behaviour may be caused due to: the inadequate performance of a task due to the perception of the person (i.e. from right to left for a right-handed person); performing a task that requires attentive decision-making to be performed too hastily; undertaking a task that does not correspond to the prevailing disposition of the person.

In this chapter the author summarises the descriptions of proprioceptive sense from different perspectives. The importance of proprioceptive sense has been shown in developmental psychology, in both the earlier and later stages of individuum formation. The author emphasises in this chapter the role of proprioception as a basis of personality and the individual differences construct. The importance of assessing behaviour at multiple levels has been pointed out by experiments of classic and modern researchers that should include not only verbal tests that would be more important for conscious mental description, but also techniques that could assess other behavioural characteristics, including automatic unconscious and pre-reflexive behaviour. The author also describes the effects of altered proprioception in humans, such as the Pinocchio effect, and other spatial perception distortions. In this chapter the importance of proprioception in acquiring new skills (embodied knowledge) as automatic and conditioned reflexive behaviour has also been highlighted. Finally, the complete picture of the individuum has been presented as a multi-layered level of a body-mind union approach.
