Bridging the Gaps in the Study of Typical and Atypical Cognitive Development: A Commentary

The articles in this special issue of the Journal of Cognition and Development examine the cognitive development of children who are following typical and atypical developmental pathways. The articles offer a mixture of theory-based considerations, reviews of the literature, and new empirical data addressing fundamental aspects of cognitive development. Our commentary considers these articles in light of comparative and dimensional approaches to the study of typicality/atypicality and offers some considerations for researchers building bridges between typical and atypical development.     

Variable preferences for sexual dimorphism in stature (SDS): Further evidence for an adjustment in relation to own height

In contemporary Western populations, some physical characteristics are sexually dimorphic, and it is known that these traits also affect human mate preferences. Height is one such characteristic, and evidence suggests that females prefer taller over shorter males, indeed, taller males have been found to have greater reproductive success. However, relative height is also important with ‘Sexual Dimorphism in Stature’ (SDS) calculated as male height/female height. Pawlowski (2003) showed that people adjust their preferences for SDS in relation to their own height in order to increase their potential pool of partners. The aim of the present study was to replicate Pawlowski’s study on a larger sample of participants, and to investigate the universality of the reported preference adjustment within European societies. We present data of 1102 men and women from three countries (Germany, Austria, and the UK) that confirm Pawlowski’s original data on a Polish sample. Moreover, the mechanism of an adjustment of SDS preferences in relation to own height was found in all three countries, suggesting that height dependent partner preference is a genuine feature in Western societies.     

Preventing Mania: A Preliminary Examination of the GOALS Program

There is strong evidence of a relationship between goal dysregulation and mania. Building on these findings, we examined the feasibility of developing a mania prevention treatment program designed to improve goal regulation skills for those with bipolar disorder. Here, we describe the process of developing a manual, delivering the intervention to a series of cases, and then conducting a small open uncontrolled trial. All participants met diagnostic criteria for bipolar I disorder based on the Structured Clinical Interview for DSM-IV and were not currently experiencing episodes of depression or mania. Ten participants (8 female, mean age = 46.7 years) were enrolled in the GOALS program and completed an average of 13.2 weekly sessions. Participants were administered the Bech-Rafaelson Mania Scale (BRMS) and the Modified Hamilton Rating Scale for Depression at baseline and termination. Some participants completed self-report scales including the Altman Self-Rating Mania Scale, the Beck Depression Inventory, and the Willingly Approached Set of Statistically Unrealistic Pursuits at baseline and termination. In addition, participants were administered a consumer satisfaction questionnaire at termination. At termination, all 10 participants found the program highly relevant and helpful. Most importantly, even though levels of mania were low initially, mean levels of manic symptoms on the BRMS decreased significantly from baseline to termination, and all 10 participants were within a healthy range (BRMS < 7) at termination. Although the lack of control group or follow-up data limits this study, preliminary evidence suggests that it is feasible to identify treatment targets by drawing from the basic research literature in bipolar disorder. Findings await replication and more careful testing within a randomized controlled trial.     

Lay Theories of Personality: Cornerstones of Meaning in Social Cognition

Lay theories (or ‘implicit theories’) are cornerstones for social cognition: people use lay theories to help them make sense of complex and ambiguous behavior. In this study, we describe recent research on the entity and incremental theories (the belief that personality is fixed or malleable). In so doing, we demonstrate that each theory does not act alone. Instead, each is associated with a set of allied beliefs, the sum total of which cohere into two distinct meaning systems. We present evidence that these meaning systems produce systematic differences in a range of fundamental social cognition processes, with important implications for the field’s understanding of trait/situation attribution, moral judgment, person memory, and stereotyping. We further argue that because meaning systems serve a central meaning‐making function, people are motivated to believe that the meaning system they are using is effective and accurate. Accordingly, we present evidence that people exhibit processing distortions and compensatory mechanisms to minimize the impact of information that violates their meaning system. We discuss the implications of these findings for the field’s understanding of basic social cognition.     

Identity in bipolar disorder: Self-worth and achievement

This article considers self and self-concept in bipolar disorder. Bipolar disorder, defined on the basis of manic symptoms, is a highly debilitating psychopathology. It is heavily grounded in biology but symptom course is still very responsive to psychological and social forces in the lives of persons who have the disorder. This review assumes an overall view of the self that is typical of personality psychology: self as traits, self as goals and aspirations, and ongoing efforts to attain those goals. In this review, we will discuss two different facets of self and identity in bipolar disorder. First, we review a body of goal pursuit literature suggesting that persons with bipolar disorder endorse heightened ambitions for attaining goals and recognition from others. Second, we will review multiple findings which suggest that among persons with bipolar disorder, self-worth depends on measurable success in an extreme way. We will consider how the intersection of these two themes may lead to unique identity challenges for people with bipolar disorder, drawing from self-report, behavioral, and neuroscience findings to critically examine this viewpoint.
