Questions about “The Self”

with one comment


In recent times there has been a lot of discussion with regard to social psychology constructs such as self-esteem, self-determination and self-affirmation. Due to rapidly changing societies and new insights into cognitive processes of memory formation some old theories of self-psychology have recently been challenged. For example Heine, Lehman, Markus and Kitayama (1999) postulated that self-esteem, conceptualized as positive self-regard, is not a universal value and should be replaced by the concept of self-enhancement. However, all those theories are closely connected to the concept of self, which in itself still remains unclear. Since there are many different interpretation of the self, many discussions end in despair, each side holding on to their specific conceptualization of the self, which are not interchangeable. But can there be any definition that fits them all? Does “talking about myself” and “exercising control over myself” relate to the same objects?

Terms such as self-esteem suggest that there is stability of that process on the influence of behavior. However people can switch between different roles (selves?) with relative ease. Reinders et al. (2003) showed that in patients with Multiple Personality Disorder, there are specific cerebral blood flow patterns mainly in the medial prefrontal cortex and the posterior associative cortices that can produce different senses of self. It is parsimonious to assume that the same process also mediates the different senses of self in healthy persons, however to a lesser extend in the sense that every self is aware of its coexistence within one person. Different selves have been postulated, such as the social self, the future self, the past self, the material self, the spiritual self… But do constructs such as self-esteem relate to all the selves in the same way or do they apply differently to different selves? Are there processes that extend through all the possible selves? Should we specify a specific self when looking at a process such as self-esteem?

People who have grown up in different cultures report that their self-concept differs in relation to the environment, as shown by Markus and Kitayama (1991). Chinese Canadians completed different measures with regard to the self, such as a measurement of independent, interdependent self-construal. When the test was conducted in a European setting (English researcher, English questions) their self-construct was predominantly independent. However if the setting (environment) was different (Chinese researcher, test in Chinese) their self-construct was more interdependent. Ross, Xun and Wilson (2002) replicated those findings and extended the method to other self-related constructs. They conclude that identities of bicultural persons may be stored in separate knowledge structures, which can be activated by the associated language.

At that point let’s take a look at different theories about the self. Descartes thought that the self was some entity that existed outside of the material body. William James defined the self as an object of knowledge consisting of whatever the individual views as belonging to himself (Epstein, 1973). George Mead noticed that the self-concept arises in social interaction as product of the individuals concerns of how others will react. Rogers saw the self as an organized fluid, but conceptual pattern of perceptions of characteristics and relationships of the ‘I’ or the ‘Me’, together with values attached to these concepts. Allport used the term proprium instead of self to stress the aspects of the individual that he or she regards of central importance and which contribute to a sense of inward unity. Furthermore the self has been described as a self-theory (Epstein, 1973),and as a cognitive knowledge structure. Sarbin remarked that behavior is organized around cognitive structures. Recently neurobiological pathways (especially the CMS, cortical midline structures) have been found to play an important role in self-referential processes. Those processes, distinguishing stimuli related to one’s own self from those that are not relevant to one’s self, might be the computing basis for the different kinds of self-concepts that have been observed.

I believe that the concept of self entails different cognitive processes, which should be looked at in the most abstract way still meaningful. Arguing from a philosophical, mechanical perspective I believe that having cognitive processes that assign a self / non-self marker to different knowledge objects should be enough to construct a theory of self. I assume that “the self” is a cognitive object that is constructed on-line, depending on the task and environment at hand. The content of those temporary self-representations is drawn for the knowledge that has been marked by the reflexive process as possessing the self-attribute. Those knowledge objects frequently used for the construction of the self should over time become chronically accessible. Such a definition of self would allow many degrees of freedom and would fit many definitions of the self previously given. Thus I propose that whenever “the self” is involved, it is necessary to specify which cognitive processes are suggested to be involved. I also propose that the environment for which the theory or hypothesis is formulated should be explicitly described. Ultimately it might be better to talk about reflexive processes instead of the self.

Non-verbal Behavior at Age 2 is significantly related to Language, Communication, and Social Outcome at Age 7

leave a comment »


Charman et al. (2005) found that non-verbal behaviour was relatively robust and reliable on the different measurements over time, whereas the other indicators where not so reliable. In that light non-verbal behaviour might be a good indicator for the development of language and communication skills specifically and quality and frequency of social interactions in general (in the long run [heterotypical development]). Non-verbal behaviour might also be an indicator of the intrinsic motivation to learn socially. That motivation might explain why non-verbal behaviour at age 2 predicted later language, communication and social skills. This is also a good example how developmental psychopathology can increase the knowledge about the processes involved in the development of a disease.

The Probabilistic Nature of Behavioural Phenotypes

leave a comment »


The probabilistic nature of behavioural phenotypes proclaims that people with a specific syndrome will have a heightened probability to exhibit specific behavior or developmental pathways that are different to others, who do not have the specific syndrome. The advantage of probabilistic nature of the construct is that it can account for exceptions and it is probably more ecological valid that a simple causal explanation. (Short excursion: I believe that statistical models that only test direct effects will be outdated in a few years, as we come to appreciate the complexity of behavioral science. Developmental psychopathology is leading the way with extensive use of structural equation modelling and a flexible theoretical framework that works with risk and protective factors. Such models have to potential to raise explanatory value beyond the simple causal models that are employed in most research today.) The behavioural phenotypes are less important for individual therapy where extensive diagnose should be performed, but they have stronger implications for intervention. If risk factors can be identified that apply for a certain population, specifically tailored interventions might be given to the whole group instead of individual therapy later on. That way specific skills and behaviors might help mentally retarded children to cross into a developmental stage, that could not have been reached without the intervention. The crucial thing is that intervention might be necessary at an early age, when children are most sensitive to the intervention, even thou the problematic behaviour might arise only in a later developmental stage.
