Performance on Raven's Matrices by African and White University Students in South Africa

Untimed Raven's Standard Progressive Matrices (SPM) were administered to 309 17- to 23-year-old students at the University of the Witwatersrand and the Rand Afrikaans University in Johannesburg, South Africa (173 Africans, 136 Whites; 205 women, 104 men). African students solved an average of 44 of the 60 problems whereas White students solved an average of 54 of the problems (p<.001). By the standards of the 1993 US normative sample, the African university students scored at the 14th percentile and the White university students scored at the 61st percentile (IQ equivalents of 84 and 104, respectively). The African–White differences were found to be greater on those items of the SPM with the highest item–total correlations, indicating a difference in g, or the general factor of intelligence. A small sex difference favoring males was found in both the African and the White samples, but unrelated to g.     

History of modern psychology in Germany1 in 19th‐ and 20th‐century thought and society

This entry surveys the characteristics, stages, and lines of development of modern psychology as an empirical psychology in Germany during the 19th and 20th centuries. These developments occurred in the context of very different political periods in German history, during a time span extending from the period of the Restoration after the Vienna Congress of 1814/15 to the present‐day “Berlin Republic”. At the centre lies the question of continuities and discontinuities in the evolution of psychology during the profound sociocultural changes that marked the politically heterogeneous developmental phases of German history. The stages are indicated by headings treating the development of psychology during the period of Restoration after 1814/15, in the German Empire (1871–1918), in the Weimar Republic (1919–1933), during the time of National Socialism (1933–45), in the Federal Republic of Germany (FRG, 1949–1990), in the German Democratic Republic (GDR, 1949–1990), and in united Germany after 1990. The result will be to demonstrate how psychology in 19th‐ and 20th‐century Germany developed from modest beginnings into a richly elaborated scientific field with diverse institutions and a differentiated professional structure. The fate of individual German psychologists during this time can be only tangentially considered.     

Effectiveness of students and parents in a psycho-educational intervention programme for children with learning problems

This study investigated the effects of involving two sources of ‘non-traditional manpower’ — namely, university students and parents — in a programme of psycho-educational intervention. It was predicted that, while intervention for children with learning problems would produce significant changes in their perceptions in relation to their families, in their scholastic skills and in their adjustment, the additional involvement of their parents would lead to even greater changes. To test this prediction, 36 children referred to a university Education Clinic were randomly divided into three equal-sized groups: youth counselling plus parent counselling (E₁), youth counselling (E₂), and a control group (C). While the hypothesised changes following intervention were not statistically demonstrated, clinical data did yield support for the effectiveness and potential value of the intervention programmes.     

Duration of auditory sensory memory in parents of children with SLI: a mismatch negativity study

In a previous behavioral study, we showed that parents of children with SLI had a subclinical deficit in phonological short-term memory. Here, we tested the hypothesis that they also have a deficit in nonverbal auditory sensory memory. We measured auditory sensory memory using a paradigm involving an electrophysiological component called the mismatch negativity (MMN). The MMN is a measure of the brain's ability to detect a difference between a frequent standard stimulus (1000 Hz tone) and a rare deviant one (1200 Hz tone). Memory effects were assessed by varying the inter-stimulus interval (ISI) between the standard and deviant. We predicted that parents of children with SLI would have a smaller MMN than parents of typically developing children at a long ISI (3000 ms), but not at a short one (800 ms). This was broadly confirmed. However, individual differences in MMN amplitude did not correlate with measures of phonological short-term memory. Attenuation of MMN amplitude at the longer ISI thus did not provide unambiguous support for the hypothesis of a reduced auditory sensory memory in parents of affected children. We conclude by reviewing possible explanations for the observed group effects.     

Intuition and the correspondence between implicit and explicit self-esteem

Four studies tested whether the perceived validity of intuition increases the correspondence between implicit and explicit self-esteem. Studies 1 and 2 found, with 2 different measures of implicit self-esteem, that people who chronically view their intuition as valid have more consistent implicit and explicit self-esteem. In contrast, people with relatively low faith in their intuition had a negative relation between implicit and explicit self-esteem, suggesting that they may overcorrect their explicit self-views for the potential bias posed by implicit self-esteem. In Studies 3 and 4, participants who were induced to view their intuition as valid reported explicit self-views (self-evaluations made under time pressure, or state self-esteem) that were more consistent with their implicit self-esteem. These results suggest that people experience implicit self-esteem as intuitive evaluations. The correspondence between implicit and explicit self-esteem among individuals who view their intuition as valid may suggest that these individuals incorporate implicit self-esteem into their explicit self-views.     

Back to Basics: The Psychoanalytic Conceptualization of Motivation

Reconsideration of motivation, a fundamental concept in psychoanalytic theory, engages us with basic assumptions and postulates of our field and draws us to the borders with neighboring scientific elaborations of the design, structure, and function of the mind. This paper presents a concept of motivation from a perspective in modern conflict theory and correlates this concept with current thinking in evolutionary biology. The challenges that this correlation raises for all psychoanalytic approaches to motivation are discussed. Natural selection has fundamentally organized motivation in accord with the principle of inclusive fitness. Adaptive motivations of self-interest achieved through social success are paramount. In mind sciences there is a growing appreciation of the innately modular mind with mounting evidence for domain and content-specific evolved psychological mechanisms, the modern term for instincts. In regard to motivation in modern conflict theory, evolved mechanisms and predispositions are innately linked to pleasure–unpleasure and include, importantly, motivations of self-interest. The pleasure–unpleasure principle regulates motivation throughout life. Early mother–child interactions are vital to the development and contextualization of motivation; however, these interactions themselves depend on mutually coadapted mechanisms that give vectors and impose constraints on every primary relationship. In evading innate contributions there is a danger of embarking on a new creationist paradigm.
