Contextual changes in the prototypicality of extreme and moderate outgroup members

Previous social categorization research has tended to treat prototypicality (the degree to which a stimulus is representative of a category) as a fixed stimulus property. In contrast, self-categorization theory sees prototypicality as an aspect of the categorization process that is dependent on features of the social context within which categorization takes place. To test this view two experiments (Ns = 256, 73) examined the perceived representativeness of extreme and moderate members of the same target outgroup in conditions which manipulated the salience of intergroup division. As predicted, the extremist was seen to be relatively more representative of the outgroup than the moderate to the extent that intergroup differences were salient. In Experiment 1 the extremist's message was also seen to be less important in low salience conditions and in Experiment 2 shifts in prototypicality were associated with changes in the evaluation of individual targets. Implications for the analysis of social categorization and stereotyping are discussed.     

Point biserial correlation coefficient and its generalization

The problem of measuring the association between two characters, one quantitative and the other qualitative, is discussed. The formula for the large sample standard error of the point biserial correlation coefficient under general conditions is derived. The point multiserial correlation coefficient is introduced and some of its properties are examined. Tests of different hypotheses appropriate to these types of problems are formulated.I wish to pay my sincerest thanks to Dr. C. R. Rao, Dr. S. K. Mitra, and the reviewers for their valuable suggestions.     

Underlying Cognitions in Gambling Behavior Among University Students1

Differences in underlying cognitions across gambling tasks were examined. The South Oaks Gambling Screen, a measure of pathological gambling, was completed by 60 undergraduate students. They also played computer‐simulated games of roulette, slots, and blackjack in a laboratory setting. The “think‐aloud” procedure was used to reveal subjects' cognitions, which were subsequently categorized into cognitive heuristics. Individuals were classified as social gamblers with and without problems and probable pathological gamblers. Results reveal that certain heuristics, including references to an explanation of their losses, hindsight bias, personification of the dealer/machine, chasing behavior, and past experiences were most frequently endorsed by probable pathological gamblers. Empirical evidence supports that probable pathological gamblers are qualitatively different from social gamblers in their emitted verbalized cognitive heuristics.     

Maternal substance use and mother–infant feeding interactions

The purpose of this study was to examine the impact of maternal polydrug cocaine use during pregnancy and associated risk factors such as maternal psychopathology and negative infant temperament on the quality of mother–infant feeding interactions at 2 months of infant age. Participants were 45 mother–infant dyads (19 cocaine‐exposed and 26 nonexposed) who were recruited at birth and assessed again 2 months of infant age. Mother–infant interactions during feeding were videotaped and coded with regard to dyadic reciprocity, maternal noncontingency, and dyadic conflict. Results indicated that maternal cocaine use was associated with higher dyadic conflict. Moreover, cocaine‐using mothers were also more likely to use marijuana and alcohol, and use of such substances was associated with lower dyadic reciprocity and higher maternal noncontingency during interactions. Results also suggested that one pathway to higher dyadic conflict during interactions among cocaine‐using mothers was through the impact of cocaine on infant risk conditions like lower gestational age and negative temperament (e.g., higher distress to novelty). Interventions focusing on promoting the quality of mother–infant interactions in combination with substance abuse treatment may be especially promising for this population. ©2001 Michigan Association for Infant Mental Health.     

Effect of schizotypy on responding maintained by free-operant schedules of reinforcement

Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules.     

Internalized Misogyny as a Moderator of the Link between Sexist Events and Women’s Psychological Distress

This study examined the relationship between internalized misogyny and two other forms of internalized sexism, self-objectification and passive acceptance of traditional gender roles. In addition, it examined the moderating role of internalized misogyny in the link between sexist events and psychological distress. Participants consisted of 274 heterosexual women who were recruited at a large southern university in the United States and completed an online survey. Results indicated that internalized misogyny was related to, but conceptually distinct from self-objectification and passive acceptance. Findings also indicated that greater experiences of sexist events were associated with higher levels of psychological distress. In addition, internalized misogyny intensified the relationship between external sexism and psychological distress.     

Neuromarketing in predicting voting behavior: A case of National elections in India

Political choice has huge importance, either expressed in the balloting place or in the exit poll, in bringing a political party to power and thus impacting the economy and society's welfare. Research in leadership and decision-making suggests that the physical characteristics and traits of an individual influence the consumer's trustworthiness. Despite being a less explored research area, studying the impact of specific verbal and non-verbal cues of a political leader through a technological lens, such as eye-tracking has been sparsely talked about. Three sets of experiments were conducted to study voters' visual attention and reactions to gage their willingness to vote. First, an eye-tracking tool was used to record the visual attention and regions of interest (ROI) of voters. Subsequently, a short survey was used to analyze the “willingness to vote”, followed by a pilot study on their attention to non-verbal cues from the candidate. Also, a sentiment analysis of the voters was gathered from social media platforms. The present study analyzed the non-verbal aspects of a political leader with regard to voting intention and found that even a few of the non-verbal cues have an influence on the willingness to vote for a candidate. The findings contribute to the literature of neuro-politics and decision-making by analyzing voters' experiences of two political leaders, Narendra Modi (NaMo) and Rahul Gandhi (RaGa) based on non-verbal cues. Political parties and candidates should focus on non-verbal cues to increase their chances of winning elections. In addition, practitioners from the industry should incorporate appropriate non-verbal cues while designing ad campaigns, personal branding, PR campaigns, and CEO addresses.     

Predictors of academic performance among Indian students

There are two dominant strains in the literature on academic performance, the attribution studies and the self-efficacy studies. The present study attempted to incorporate these two strains while examining the academic performance of engineering undergraduate students in India. Time management and perceived stress were included in the model to predict grade goals and academic performance. Two age groups were compared to assess the impact of developmental change on the predictors of academic performance. Two studies were conducted with 372 first year students and 232 third, fourth and fifth year students from the same engineering institute. Different predictors emerged for the two groups, reflective of developmental change. Self-efficacy emerged as an important predictor for the older students.     

Evaluation eines präventiven Beratungskonzeptes für Kinder körperlich kranker Eltern

Children of parents suffering from a serious disease (e.g. cancer, multiple sclerosis, Aids) are at increased risk for mental health problems. Empirically based interventions for these children are missing. At the University Medical Centre Hamburg-Eppendorf, a preventive short-term counselling service has been existing since July 2000. Results from a 6-month evaluation (n=50) are presented. The evaluation encompasses a retrospective interrogation in a multiperspective und multidimensional approach. Most families experienced the intervention as helpful and supportive in coping with the multiple stressors of the situation. Out of a previously defined list of 12 intervention goals, enhancing anticipatory grief in children, their active coping behaviour as well as parents’ sense of their own parenting competence were identified as the most important foci of the counselling interventions, as reported by parents, children and therapists.     

A conceptual model for the development of externalizing behavior problems among kindergarten children of alcoholic families: role of parenting and children's self-regulation

The purpose of this study was to test a conceptual model predicting children's externalizing behavior problems in kindergarten in a sample of children with alcoholic (n = 130) and nonalcoholic (n = 97) parents. The model examined the role of parents' alcohol diagnoses, depression, and antisocial behavior at 12-18 months of child age in predicting parental warmth/sensitivity at 2 years of child age. Parental warmth/sensitivity at 2 years was hypothesized to predict children's self-regulation at 3 years (effortful control and internalization of rules), which in turn was expected to predict externalizing behavior problems in kindergarten. Structural equation modeling was largely supportive of this conceptual model. Fathers' alcohol diagnosis at 12-18 months was associated with lower maternal and paternal warmth/sensitivity at 2 years. Lower maternal warmth/sensitivity was longitudinally predictive of lower child self-regulation at 3 years, which in turn was longitudinally predictive of higher externalizing behavior problems in kindergarten, after controlling for prior behavior problems. There was a direct association between parents' depression and children's externalizing behavior problems. Results indicate that one pathway to higher externalizing behavior problems among children of alcoholics may be via parenting and self-regulation in the toddler to preschool years.
