Effects of group membership and identification on categorization and subtyping in memory

A meta-analysis (N=229) was performed to test effects of group membership and identification on the use of (sub)categories across five of our own experiments. In each experiment a name matching paradigm was used to investigate the extent to which (sub)categories were used to organize social information in memory. Four subcategories (male students, female students, male teachers, female teachers) were available to categorize the stimulus persons, as a result of crossing sex and academic status. Comparing findings over studies yielded (a) a strong tendency to use subtypes to organize social information in memory; (b) no support for the prediction of stronger subtyping of ingroup members than of outgroup members; (c) support for the prediction that subjects high on identification with own-sex group would use subtypes within gender categories to a lesser extent than subjects low on identification with own-sex. (d) In addition, it appeared that sex and academic status were used as independent overall categorizations as well, although superordinate categorization effects were caused for a large part (75–87 per cent) by name-confusions within subcategories, which suggests a preference for the use of subtypes over superordinate categories. © 1998 John Wiley & Sons, Ltd.     

Holistic face processing is mature at 4 years of age: evidence from the composite face effect

Although it is acknowledged that adults integrate features into a representation of the whole face, there is still some disagreement about the onset and developmental course of holistic face processing. We tested adults and children from 4 to 6 years of age with the same paradigm measuring holistic face processing through an adaptation of the composite face effect [Young, A. W., Hellawell, D., & Hay, D. C. (1987). Configurational information in face perception. Perception, 16, 747-759]. In Experiment 1, only 6-year-old children and adults tended to perceive the two identical top parts as different, suggesting that holistic face processing emerged at 6 years of age. However, Experiment 2 suggested that these results could be due to a response bias in children that was cancelled out by always presenting two faces in the same format on each trial. In this condition, all age groups present strong composite face effects, suggesting that holistic face processing is mature as early as after 4 years of experience with faces.     

Controlling your mind without ironic consequences: Self-affirmation eliminates rebound effects after thought suppression

Thought suppression can ironically lead to a rebound of unwanted thoughts [Wegner, D. M. (1994). Ironic processes of mental control. Psychological Review, 101, 34-52.]. The present research explored whether self-affirmation may eliminate rebound effects after thought suppression. Participants either suppressed or used stereotypes in an impression formation task. Subsequently, self-affirmation was manipulated by providing participants with positive or neutral personality feedback, and stereotype accessibility was assessed. The results showed that suppression led to a rebound of stereotypic associations among neutral-feedback participants, but not among positive-feedback participants. The authors conclude that self-affirmation enhances the efficiency of mental control.     

Transverse diffusivity of cerebral parenchyma predicts visual tracking performance in relapsing–remitting multiple sclerosis

This study investigated the relation between cerebral damage related to multiple sclerosis (MS) and cognitive decline as determined by two classical mental tracking tests. Cerebral damage in 15 relapsing–remitting MS patients was measured by diffusion tensor imaging (DTI). Fractional anisotropy, longitudinal and transverse diffusivity were defined in the cerebral parenchyma. Cognitive performance of the MS patients was assessed with the oral response format of the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT). A significant correlation was found between performance on the SDMT and the fractional anisotropy in the brain. This correlation was predominantly induced by transverse diffusivity. Transverse diffusivity refers to the diffusion across fibers rather than along the fibers and is believed to be a specific marker for axonal loss and demyelination associated with MS. No significant association between DTI-measures and PASAT performance was found and this negative finding was mainly attributed to psychometric qualities. These results indicate that diffusivity along the non-principal diffusion direction, a possible signature of MS-related white matter pathology, contributes to information processing speed as measured with the SDMT, a task that requires close visual tracking and a widely used clinical marker for cognitive decline in MS.

This contribution describes the present state of research concerning human crying, in particular the conditions that induce crying, the context and the intra-individual and inter-individual effects of shedding emotional tears. Crying is regarded not only as a psychobiological process with certain effects on the physical and mental well-being of the crying person, but also as a process which has a strong impact on the social environment. A comprehensive model of adult crying is presented, which not only accounts for these behavioral differences, but which also covers the reasons for crying, its social contexts, its consequences for the crying person and its inter-individual effects. In addition, the role of moderating variables is clarified. It is emphasized that there is no clear evidence in support of the hypothesis that crying brings relief and is healthy. It is suggested that the appropriate question is ?under which conditions can crying bring relief?” rather than ?does crying bring relief?” Furthermore, the impact of crying on the social environment is pointed out by which it facilitates the provision of social support and it may reduce aggression. Seen from a coping perspective, crying thus may both serve emotion-focused coping and problem-focused coping functions.

Transhumanism and the Wisdom of Old Genes is Neurotechnology as Source of Future Happiness?

Technological progress seems to open ways for redesigning the human organism. This means that the affective system that is built into the brain by evolution can be redesigned with intent. One of the consequences will be that the word progress will get a new meaning. Progress won't be confined to enhancing the conditions of living, but it will change the way we react to the world. These possibilities are explored in a new kind of biological utopism called 'transhumanism'. This school foresees that a restructured human brain will give rise to 'more varied experience, lifelong happiness and exhilarating peak experiences everyday'. This essay considers the reality value of that expectation in the light of the current psychology of affects, in particular of presumed functions of hedonic experience. It is concluded that transhumanism overlooks that happiness will lose its meaning if it is treated as an isolated feeling. The affective system in our brain needs strong ties with the on-going interaction of the individual with its environment. Making people happier without enhancing the grip on their life will be contra-productive.     

Do Automatic Self-Associations Relate to Suicidal Ideation?

Dysfunctional self-schemas are assumed to play an important role in suicidal ideation. According to recent information-processing models, it is important to differentiate between ‘explicit’ beliefs and automatic associations. Explicit beliefs stem from the weighting of propositions and their corresponding ‘truth’ values, while automatic associations reflect more simple associations in memory. Both types of associations are assumed to have different functional properties and both may be involved in suicidal ideation. Thus far, studies into self-schemas and suicidal ideation focused on the more explicit, consciously accessible traces of self-schemas and predominantly relied on self-report questionnaires or interviews. To complement these ‘explicit’ findings and more directly tap into self-schemas, this study investigated automatic self-associations in a large scale community sample that was part of the Netherlands Study of Depression and Anxiety (NESDA). The results showed that automatic self-associations of depression and anxiety were indeed significantly related to suicidal ideation and past suicide attempt. Moreover, the interactions between automatic self-depressive (anxious) associations and explicit self-depressive (anxious) beliefs explained additional variance over and above explicit self-beliefs. Together these results provide an initial insight into one explanation of why suicidal patients might report difficulties in preventing and managing suicidal thoughts.     

Vacationers Happier,but Most not Happier After a Holiday

The aim of this study was to obtain a greater insight into the association between vacations and happiness. We examined whether vacationers differ in happiness, compared to those not going on holiday, and if a holiday trip boosts post-trip happiness. These questions were addressed in a pre-test/post-test design study among 1,530 Dutch individuals. 974 vacationers answered questions about their happiness before and after a holiday trip. Vacationers reported a higher degree of pre-trip happiness, compared to non-vacationers, possibly because they are anticipating their holiday. Only a very relaxed holiday trip boosts vacationers’ happiness further after return. Generally, there is no difference between vacationers’ and non-vacationers’ post-trip happiness. The findings are explained in the light of set-point theory, need theory and comparison theory.
