Future-event schemas and certainty about the future: automaticity in depressives' future-event predictions.

The proposition was tested that depressives make predictions about the future based on a pessimistic future-event schema. Participants varying in depression predicted whether positive and negative events would happen to them (or to an average person) in the future by pressing yes or no at a computer terminal as quickly as possible, either under a concurrent attentional load or under no such load. As hypothesized, depressives predicted more negative events and fewer positive events than did mild depressives or nondepressives and showed greater automaticity in their predictions. That is, the attentional load did not increase depressives' response latencies for either negative or positive events, even though it did so reliably for both mildly depressed and nondepressed individuals. Depressives may thus possess a highly developed future-event schema that operates efficiently in enabling future-event predictions.     

Effects of pyridoxine on dreaming: a preliminary study

The effect of pyridoxine (Vitamin B-6) on dreaming was investigated in a placebo, double-blind study to examine various claims that Vitamin B-6 increases dream vividness or the ability to recall dreams. 12 college students participated in all three treatment conditions, each of which involved ingesting either 100 mg B-6, 250 mg B-6, or a placebo prior to bedtime for a period of five consecutive days. The treatment conditions were completely counterbalanced and a two-day wash-out period occurred between the three five-day treatment blocks. Morning self-reports indicated a significant difference in dream-salience scores (this is a composite score containing measures on vividness, bizarreness, emotionality, and color) between the 250-mg condition and placebo over the first three days of each treatment. The data for dream salience suggests that Vitamin B-6 may act by increasing cortical arousal during periods of rapid eve movement (REM) sleep. An hypothesis is presented involving the role of B-6 in the conversion of tryptophan to serotonin. However, this first study needs to be replicated using the same procedures and also demonstrated in a sleep laboratory before the results can be considered certain.     

Rethinking paradigms in geriatric ethics

This paper calls for a shift away from autonomy as the central value in geriatric ethics. In treatment and experimental settings, differences between older and younger adults are easily attributed to deficiencies on the part of the elderly when autonomy is the central value. Overemphasis on the concept of autonomy skews our understanding of human relationships toward excessively rational models, distracts attention from important physical and social characteristics of aged persons, and results in ethics by default. This paper describes several principles that would be more useful starting points than autonomy in developing a geriatric ethic.     

Well-being on campus: testing the effectiveness of an online strengths-based intervention for first year college students

The present research examined the effectiveness of an 8-week online strengths-based intervention in promoting subjective and psychological well-being of first year university students. The intervention was composed of five modules pertaining to (a) finding and cultivating on character strengths, (b) regulation of emotions and increasing positive emotions, (c) constructive communication, establishing social connectedness and positive relationships (d) effective decision-making and problem solving and (e) achieving flow and practicing gratitude. A total 92 students volunteered to participate in the study. They were randomly assigned to either the intervention or a control group. Students’ quality of life (psychological health and social relations domains), life satisfaction, subjective happiness and ontological well-being were measured before and after the intervention. Significant improvements in well-being of intervention group participants were observed over an 8-week period whereas control group participants did not show a significant increase in any of these well-being variables.     

The effect of a delayed weekend sleep pattern on sleep and morning functioning

Abstract

It is a common practice for young adults to delay their weekend sleep schedule. The present study was designed to assess the effect of this sleep pattern on the sleep of Sunday night and the functioning of Monday morning. The sleep schedules of 30 young adults were manipulated for 2 consecutive weeks. In the Habitual-Sleep (HS) week, subjects followed their habitual sleep schedule throughout the week; in the Delayed-Sleep (DS) week, subjects' sleep schedule on Friday and Saturday nights were delayed by two hours. Compared to the HS week, subjects showed significantly lower subjective sleepiness near bedtime and trends of longer sleep onset latency on Sunday night in the DS week. In addition, there was both lowered cognitive performance and overall mood rating on Monday morning in the DS week. The delayed weekend sleep pattern contributes to Sunday night insomnia and the Monday morning “blues”.     

Television Exposure and Children's Decoding of Nonverbal Behavior1

Two studies considered the way in which the magnitude of exposure to television relates to children's understanding and interpretation of others' nonverbal behavior. In the first study, 6th graders made judgments regarding other children whose nonverbal facial behavior did not match their internal emotional state. Results showed that heavier television viewers held a less differentiated, more simplistic view of the consequences of nonverbal self-presentation strategies. In the second study, children in Grades 2 through 6 made judgments of others' nonverbal expressions of emotion. As predicted, heavier television viewers were better at decoding others' nonverbal expressions than lighter viewers, presumably because of their greater exposure to nonverbal displays of emotion on television. In addition, nonverbal decoding skills improved with age.     

Beyond Pittsburgh: protocols for controlled non-heart-beating cadaver organ recovery

Much of the ethical debate about controlled non-heart-beating cadaver (NHBC) organ recovery has focused on the University of Pittsburgh Medical Center (UPMC) protocol. Some commentators have voiced serious reservations about the ethical acceptability of that protocol; others have argued that the protocol contains sufficiently stringent ethical safeguards to warrant a limited and carefully monitored trial at UPMC. UPMC is not the only organization pursuing controlled NHBC organ procurement, however. The study of organ procurement organizations described in this article suggests that controlled NHBC organ procurement is a practice that, if not yet widespread, is certainly no longer isolated to a few organizations in which it is carefully monitored. Rather, it is being carried out under a variety of circumstances, many of which are less carefully constrained ethically than at the University of Pittsburgh Medical Center. The next stage of the ethical debate should focus on issues that are arising in a variety of settings as the practice spreads.
