Generalization of positive attitude as a function of subgroup and superordinate group identifications in intergroup contact

The role of category salience in mediating the effects of intergroup contact was examined. One theoretical model proposes that some psychological salience of subgroup categories is necessary to facilitate the generalization of attitude change beyond the immediate contact situation. Another argues that a re‐categorization of the subgroups into a new superordinate category is more beneficial, whilst a third suggests that de‐categorizing the situation entirely is optimal. An alternative view, which combines the first two models, proposes a Dual Identity strategy (simultaneous high superordinate and high subgroup categorization) as an important mediator of the relationship between contact variables and intergroup attitudes. In the study, participants (N = 114) undertook a cooperative intergroup task under four conditions of category salience: ‘subgroup’, ‘superordinate’, ‘superordinate and subgroup’, and ‘no group salience’. Evaluative ratings and symbolic reward allocations both for the groups encountered (contact) and those outside the situation (generalization) provided measures of intergroup bias. Bias within the contact situation was mainly eliminated in all conditions. However, on the more generalized bias measures, only the ‘superordinate’ and ‘superordinate and subgroup’ (Dual Identity strategy) conditions maintained this low level; in the other two conditions intergroup bias resurfaced. A combination of the first two models is proposed. Copyright © 2002 John Wiley & Sons, Ltd.     

Antecedents and consequences of acculturation preferences of non‐indigenous Chileans in relation to an indigenous minority: longitudinal survey evidence

Two longitudinal survey studies were conducted with non‐indigenous majority Chilean participants (Ns = 755 cross‐sectional, 198 longitudinal in study 1; 390 cross‐sectional, 333 longitudinal in study 2). In contrast to most previous research, the longitudinal design allowed to test directly the hypothesised causal direction of effects. There were two broad research questions. Firstly, what is the relationship between acculturation preferences of non‐indigenous majority members and negative affect towards the indigenous Mapuche? More specifically, does a preference for integration lead to less negative affect than a preference for assimilation, separation or marginalisation? Related to this, do the dimensions of culture maintenance and contact taken singly predict negative affect and/or vice versa? Secondly, does knowledge about the Mapuche causally and indirectly influence acculturation preferences, partially mediated by sympathy with the Mapuche? Results confirmed that knowledge influenced acculturation preferences, and that sympathy was a partial mediator. Acculturation preferences, in turn, influenced negative affect. The contact dimension underlying the categorical acculturation strategies was a predictor of outcomes, while the culture maintenance dimension was not. Implications of the findings are discussed.

An experimental study of some hypothesized behaviors and personality variables of college student procrastinators

Aitken's Procrastination Inventory was administered to 200 college students. Scores were correlated with extraversion and neuroticism scores of the revised Eysenck Personality Questionnaire. Procrastination was positively correlated with extraversion and curvilinearly related to neuroticism. Forty procrastinators and nonprocrastinators were further tested. Procrastinators showed a significant tendency to underestimate the time needed to complete a reading task. They also showed a preference for beginning a task by performing the simpler portions first. Treatment and theoretical implications are discussed.     

Comparisons and perceived deprivation in ethnic minority settings

Two studies investigated comparison choices among ethnic minorities and majorities. The perceived status of the self vis-á-vis different comparison targets also was assessed. Antecedents and consequences of comparisons and relative deprivation were examined. Predictions were derived from social comparison, stigma, social identity, and relative deprivation research. Two surveys were conducted, one in London with mainly Asian participants (N = 235) and one in Germany with Turkish and Aussiedler participants (N = 166) and German majority members (N = 351). Participants preferred intragroup and temporal comparisons (with other ingroup members and with the self in the past) to various types of cross-group comparisons (with outgroup members). Perceived similarity and contact with a target positively predicted interest in comparing with this target, and perceived higher status of the target was a negative predictor. Some evidence was found that feelings of deprivation depend on comparison choices. Deprivation negatively predicted self-esteem and life satisfaction. Deprivation and group identification were negatively correlated.     

Oxford cognitive screen: A critical review and independent psychometric evaluation

The Oxford cognitive screen (OCS) is a stroke-specific cognitive screening assessment. Although the test developers have provided psychometric information for the assessment, the OCS has received minimal external scrutiny, with which to triangulate the underpinning psychometrics. The purpose of this study is to provide a critical review and independent validation of the OCS. This study analysed data from an anonymised clinical database, which consisted of 316 patients who were assessed using the OCS on an Acute Stroke Unit. The rates of impairment on tests of memory and receptive communication were lower than expectation, suggesting that these subtests may be relatively insensitive. Patients with aphasia were more likely to be unable to categorised as impaired on non-language tests, suggesting that they remain sensitive to language processing or non-dominant hand usage. Some of the subtests of the OCS achieve high retest reliability, which makes them good candidates for measuring cognitive change over time. Although the OCS has many advantages, it is also important to adequately consider its limitations, that is insensitivity to memory problems, the potential confounding impact of non-dominant hand usage, and the potential that some tests may sample overall cognitive ability instead of domain-specific functioning.     

Somatovisceral interactions in visceral perception: Abdominal masking of colonic stimuli

Clinical and experimental evidence on referred pain and spinal-afferent convergence demonstrates a close relationship between visceral and somatosensory perception, which is important for current models of symptom perception and central body representation. The study uses a psychophysical approach to quantify these interactions at the perceptual level, taking into account problems of comparable intermodal scaling and the role of awareness. An experiment on somatosensory masking of distension stimuli in the colon is reported in which a multiple staircase method of forced choice discrimination with concurrent sensation ratings was employed. Results showed perceptual masking of visceral by abdominal stimuli but not vice versa. The masking effect was not enhanced by intratomal placement of the abdominal stimulus in the lower left quadrant. This contradicts the spinal sensory convergence model and points to perceptual interactions at higher brain levels. Loglinear analysis of relations between discrimination and subjective sensation revealed qualitative differences of somatovisceral perception at the preconscious as compared to the conscious level. This argues for a two-process model of integrative body perception.     

Procedural justice and preferential treatment: A brief review and comment

To put Singer’s (1992) work on relative deprivation and responses to preferential treatment in context, studies from a procedural justice perspective are reviewed. That review suggests that the psychological dynamics of preferential treatment are well accounted for by concepts derived from theories of procedural justice. It is thus argued that, to be parsimonious, Singer’s work is best conceptualized in procedural justice rather than relative deprivation terms.     

Awareness is awareness is awareness? Decomposing different aspects of awareness and their role in operant learning of pain sensitivity

Regarding awareness as a consistent concept has contributed to the controversy about implicit learning. The present study emphasized the importance of distinguishing aspects of awareness in order to determine whether learning is implicit. By decomposing awareness into awareness of contingencies, of the procedure being a learning task, and of the reinforcing stimuli, it was demonstrated that implicit operant learning modulated pain sensitivity. All of these aspects of awareness were demonstrated to not be necessary for learning. Additionally, discrimination of contingencies was not necessary on different levels of processing as demonstrated by a verbal and a behavioral method. It was demonstrated that explicit cognitive processes about one's own behavior, impaired learning, even though these cognitions were not immediately related to the learning process. The results of this study are of special interest in the context of pain, since implicit operant learning can explain the gradual development of hypersensitivity in chronic pain.
