Exploring the within-person coupling of sleep and cognition in older African Americans

This study examined the within-person relationship between sleep and cognitive functioning. Fifty community-dwelling African Americans (age range = 50-80 years) were asked to report their sleep duration and quality the previous evening and to complete cognitive measures over 8 occasions within a 2-3 week period. A within-person daily change in sleep duration was significantly associated with worse global cognitive performance. The greater an individual deviated away from his or her average sleep duration on a particular day, the more likely his or her performance would decline. These results demonstrate that the sleep-cognition relationship can be observed at a within-person level of analysis.     

Time flies when we read taboo words

Does time fly or stand still when one is reading highly arousing words? A temporal bisection task was used to test the effects of sexual taboo words on time perception. Forty participants judged the duration of sexual taboo, high-arousal negative, high-arousal positive, low-arousal negative, low-arousal positive, and category-related neutral words. The results support the hypothesis that sexual taboo stimuli receive more attention and reduce the perceived time that has passed (“time flies”)—the duration of high sexual taboo words was underestimated for taboo-word stimuli relative to all other word types. The findings are discussed in the context of internal clock theories of time perception.     

Cognitive-Behavioral Therapy for Depression in an Older Gay Man: A Clinical Case Study

Although strong evidence supports cognitive-behavioral therapy for late-life depression and depression in racial and ethnic minorities, there are no empirical studies on the treatment of depression in older sexual minorities. Three distinct literatures were tapped to create a depression treatment protocol for an older gay male. Interventions were deduced from the late-life depression literature, culturally adapted CBT protocols for racial minorities, and the emerging social and developmental psychological theories for lesbian, gay, and bisexual populations. Specific treatment interventions, processes, and outcomes are described to illustrate how these literatures may be used to provide more culturally appropriate and effective health care for the growing, older sexual minority population.     

Out of sight,out of mind: The attentional blink can eliminate synaesthetic colours

Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were embedded an oriented grating (T1) and a letter-prime (T2), forming a modified attentional blink (AB) task. At the end of the stream a coloured probe appeared that was either congruent or incongruent with the synaesthetic colour elicited by the letter-prime. When the prime was attended, synaesthetes showed a reliable effect of prime-probe congruency. In contrast, when the prime appeared at 350 ms following T1 (during the AB), the congruency effect was eliminated. Our findings suggest that focused attention is crucial for inducing letters to elicit colours in synaesthesia.     

Planning in sentence production: Evidence for the phrase as a default planning scope

Controversy remains as to the scope of advanced planning in language production. Smith and Wheeldon (1999) found significantly longer onset latencies when subjects described moving-picture displays by producing sentences beginning with a complex noun phrase than for matched sentences beginning with a simple noun phrase. While these findings are consistent with a phrasal scope of planning, they might also be explained on the basis of: (1) greater retrieval fluency for the second content word in the simple initial noun phrase sentences and (2) visual grouping factors. In Experiments 1 and 2, retrieval fluency for the second content word was equated for the complex and simple initial noun phrase conditions. Experiments 3 and 4 addressed the visual grouping hypothesis by using stationary displays and by comparing onset latencies for the same display for sentence and list productions. Longer onset latencies for the sentences beginning with a complex noun phrase were obtained in all experiments, supporting the phrasal scope of planning hypothesis. The results indicate that in speech, as in other motor production domains, planning occurs beyond the minimal production unit.     

A review of recent studies on differential reinforcement during skill acquisition in early intervention

Although the use of differential reinforcement has been recommended in previous investigations and in early intervention curriculum manuals, few studies have evaluated the best method for providing differential reinforcement to maximize independent responding. This paper reviews previous research on the effectiveness of differential reinforcement as treatment and describes important areas of future research.     

Who Cares? The Role of Job Involvement in Psychological Contract Violation

This study examined survey data from full‐time employees employed in a variety of occupations. We empirically examined how psychological involvement with one's job affects reactions to psychological contract violation. Data for control variables (i.e., age, gender, organizational tenure), the independent variable (i.e., psychological contract violation), and the moderator (i.e., job involvement) were taken at Time 1; and dependent variables (i.e., depressed mood at work, turnover intention) were taken at Time 2. Results illustrated that job involvement was an important construct in understanding individuals' negative reactions to psychological contract violations. Implications and limitations are discussed, and suggestions for future research are offered.     

Mating competitors increase religious beliefs

It has been presumed that religiosity has an influence on mating behavior, but here we experimentally investigate the possibility that mating behavior might also influence religiosity. In Experiment 1, people reported higher religiosity after looking at mating pools consisting of attractive people of their own sex compared to attractive opposite sex targets. Experiment 2 replicated the effect with an added control group, and suggested that both men and women become more religious when seeing same-sex competitors. We discuss several possible explanations for these effects. Most broadly, the findings contribute to an emerging literature on how cultural phenomena such as religiosity respond to ecological cues in potentially functional ways.     

Understanding Adolescent Substance Abuse: Prevalence,Risk Factors,and Clinical Implications

From a developmental perspective, adolescence is a time of gaining independence, experimentation, and taking risks. One area of experimentation associated with adolescence is substance use. For counselors working with adolescents who use or abuse substances, or both, it is important to understand the scope of the problem and ways to effectively work with this population. This article provides counselors with current information on adolescent substance abuse and suggestions for clinical work.
