INTEGRATING GENDER AND ETHNICITY INTO PSYCHOLOGY COURSES

In this introduction to the special issue on teaching about gender and ethnicity in psychology, we consider the assumptions underlying an inclusive curriculum that pays attention to gender and ethnicity and address why such a curriculum has merit. We review empirical studies, assessing whether existing curricula are inclusive, and present an overview of the articles and the recurrent themes. These themes include the complexity of the interaction between ethnicity and gender; the difficulty of deciding which of the many possible ethnic groups to include in course material; the dominance of evaluative comparison in discussions of differences among groups; the interdisciplinary nature of research on ethnicity; and the tendency in psychology to ignore the importance of the power differences that confound analyses of the effect of ethnicity and gender.     

Different patterns of cognitive slowing produced by Alzheimer's disease and normal aging

Aging has previously been shown to produce a generalized proportional slowing of all cognitive operations. In contrast, the present results suggested that Alzheimer's disease produces a disproportionate reduction in the speed with which patients carry out one or more mental operations. The tasks that demented patients found particularly difficult involved either a self-directed search of their lexicon or the use of familiarity information.     

Adult age differences in the effects of sentence context and stimulus degradation during visual word recognition

I investigated adult age differences in the efficiency of feature-extraction processes during visual word recognition. Participants were 24 young adults (M age = 21.0 years) and 24 older adults (M age = 66.5 years). On each trial, subjects made a word/nonword discrimination (i.e., lexical decision) regarding a target letter-string that was presented as the final item of a sentence context. The target was presented either intact or degraded visually (by the presence of asterisks between adjacent letters). Age differences in lexical decisions speed were greater for degraded targets than for intact targets, suggesting an age-related slowing in the extraction of feature-level information. For degraded word targets, however, the amount of performance benefit provided by the sentence context was greater for older adults than for young adults. It thus appears that an age-related deficiency at an early stage of word recognition is accompanied by an increased contribution from semantic context.     

Attentional bias to threat: Roles of trait anxiety, stressful events, and awareness

Attentional biases for threat stimuli were assessed in high and low trait anxious subjects (n = 66) using a probe detection task. To examine the effects of trait anxiety and situational stressors, each subject was tested three times: Under no stress, laboratory-induced stress, and examination-induced stress. To evaluate the role of awareness, half the word stimuli were presented very briefly (14 msec) and masked, and the other half were presented for 500 msec without a mask. Results showed that high trait anxious subjects under exam stress showed an attentional bias towards unmasked threat stimuli compared with low trait subjects. This effect was not found under lab-induced stress, suggesting that the attentional bias for unmasked threat in high trait subjects may be a function of a prolonged stressor, rather than a transient increase in state anxiety. The results from the masked exposure condition were not predicted; high trait anxious subjects shifted attention towards the spatial location of threat words despite lack of awareness of their lexical content, but this bias was only apparent in the no-stress condition. The results are discussed in relation to recent cognitive theories of anxiety.     

Exchange delays and impulsive choice in adult humans.

Choice responding by adult humans in a discrete-trial task was examined as a function of conditions that manipulated either the delay to point delivery or the delay between points and their exchange for money. In point-delay conditions, subjects chose between an "impulsive" alternative that provided a small amount of points immediately and a "self-control" alternative that provided a larger amount of points delayed by 15, 30, or 60 s. Points were exchanged for money immediately following the session. Subjects preferred the self-control alternative. In exchange-delay conditions, subjects chose between a small amount of points exchangeable for money immediately following the session and a larger amount of points exchangeable for money after 1 day, 3 weeks, or 6 weeks. A self-control preference observed for all subjects in the 1-day exchange-delay condition reversed to exclusive impulsive preference for 4 of the 6 subjects when choice conditions involved exchange delays of 3 or 6 weeks. These results show that human choice is sensitive to the manipulation of exchange delays and that impulsive preference can be obtained with exchange delays on the order of weeks.     

Optimism and Pessimism in Business Leaders1

Male business leaders responded to 3 instruments, the Leadership Practices Inventory (LPI-SELF), the Kirton Adaption-Innovation Inventory (KAI), and a measure of optimism and pessimism (O/P). Approximately 5 to 6 (range = 3 to 9) of each of the 48 leaders' direct reports rated their leaders on the LPI (LPI-OBSERVER) and also responded to the O/P instrument. As predicted, both the leaders and their direct reports had lower mean scores on pessimism than a normative group; neither group differed from the norm on optimism. The leader KAI scores were negatively correlated with pessimism, and positively, though not significantly so, with optimism. Optimism was positively correlated with 2 factors of the LPI-OBSERVER, but pessimism was not correlated with any of the five LPI factors.     

Arbitrariness of frustration: Inhibition or instigation effects on aggression

The purpose of the present research was to assess the relative influence of instigation or inhibition in mediating retaliation after arbitrary or non-arbitrary frustration. Sixty-four men were asked to learn a concept that was being taught by a peer. Although all men were frustrated, half were deliberately frustrated while the other half were not deliberately frustrated by the teacher. Following the task, the learner was given the opportunity to prevent the teacher from gaining employment under conditions where his evaluation was either anonymous or to be made public. The results of a 2 × 2 analysis of variance yielded several significant effects. The data revealed that subjects rejected the teacher more when the frustration was arbitrary than when it was non-arbitrary. Moreover, when the evaluation was anonymous, subjects rejected the teacher more than when the evaluation was to be made public. Furthermore, the difference in the amount of rejection expressed between arbitrary and non-arbitrary conditions was greater when the evaluation was anonymous than when it was public. These results were interpreted as demonstrating the greater contribution of instigatory rather than inhibitory factors in expressing aggression following deliberate or non-deliberate frustration.     

Mood and the self-reference bias in recall

Hypotheses linking a negative recall bias (or negative self-schema) with vulnerability to depression were tested using an experimental mood-induction task. Extent of bias in student subjects was found to be unstable over a 4-month period, but different measures of memory bias within one session were highly correlated. Marginally significant correlations in the expected direction were found between estimates of recall bias and mood state, whether measured at the same or at different times. Change in mood following induction did not relate to change in bias, suggesting that the observed differences in recall are not a simple function of transient mood state alone. Equally, the initial recall bias did not predict the extent of mood shift following induction, as would be expected if a negative self-schema determined ease of mood shift in a negative direction. However, significant correlations were found between negative recall bias and self-reported frequency and severity of depression, lending equivocal support to the negative self-schema model.
