Dispositional Optimism/Pessimism and Coping Strategies: Predictors of Psychosocial Adjustment of Rheumatoid and Osteoarthritis Patients1

Because rheumatoid arthritis (RA) has a more unpredictable course than osteoarthritis (OA), we hypothesized that generalized expectancies (optimistic/ pessimistic) influence the psychosocial adjustment of RA patients, whereas disease severity influences the adjustment of OA patients. Path analysis (LISREL VI) revealed that pessimistic RA patients (N= 107) and the more physically disabled OA patients (N= 108) reported poorer adjustment. The hypothesized mediating role of coping was supported for the RA but not the OA sample; that is, pessimism was associated with poor adjustment through greater use of wishful thinking coping. Unexpectedly, problem-solving coping was not found to mediate the optimism adjustment relationship.     

Aerobic conditioning and stress reduction: Participation or conditioning?

The efficiency of an aerobic conditioning program (jogging) is compared to cognitive therapy (stress inoculation) and a waiting list control in modifying self-reported chronic stress. The participants were community residents; 48 were females and 25 were males. Treatment sessions were conducted over a 10-week period with subjects meeting in small groups for 1$\text{1}\text{2}$ hours per week. The State/Trait Inventories, a Tension Thermometer and a submaximal bicycle ergometer test were administered pre, post and follow-up. Repeated measures, multivariate analysis of variance indicated that both treatments were effective in reducing stress compared to the waiting list control and that these changes were maintained at 3-month follow-up. Multivariate analysis indicated that participants with higher initial levels of aerobic fitness did not report less stress, while participants who obtained higher levels of fitness during the conditioning program fared no better in reducing stress than their counterparts who obtained lower levels of aerobic fitness. These findings are of interest because they suggest that the psychosocial components of the fitness program were active ingredients of treatment rathee than the effects of improved cardiovascular functioning.     

Perceptual differences between reading handwritten and typed words

Perceptual differences between reading handwritten and typed words were investigated in a series of three experiments. In the first two experiments, a Sternberg memory search paradigm was employed, with either typed or handwritten probes. The reaction time to classify handwritten probes was slower than for typed probes, but memory search took place at the same rate for both kinds of probe. In the third experiment, the latencies for naming the written and typed words differed by the same amount of time as the overall difference between the same stimuli in the memory search task. These findings indicate that only perceptual processes are differentially affected by the differences between typed and written words. Furthermore, in these tasks the independence of encoding and memory search makes it unlikely that processes of perceptual indentification use expectations or analysis-by-synthesis based on the information in immediate memory     

Examining the efficacy of truth/lie discussions in predicting and increasing the veracity of children's reports

This study investigated whether children's ability to reason about truths and lies influenced their truth-telling behavior. Four-six-year-old children (n=118) played a game that was intended to motivate children to use deception to hide a minor transgression. Next, an interviewer gave children one of four preliminary discussions. Children received a typical forensic truth/lie discussion (TLD), a developmentally appropriate and more elaborate TLD, or one of two discussions that controlled for the time spent conversing with children. Children were interviewed about the event. The results revealed that children's performance on the truth/lie questions did not predict their truth-telling behavior. Regardless of their performance on truth/lie questions, children who received TLD's gave more honest reports than children who did not receive TLD's. These results suggest that discussing truths and lies with children may promote truth-telling behavior. However, the results cast doubt on the validity of using children's performance on truth/lie questions as a measure of competency.     

The effect of jury deliberations on jurors' propensity to disregard inadmissible evidence

The goal of this research was to examine the effect of jury deliberations on juror's propensity to disregard inadmissible evidence. Extant research is inconclusive; some research indicates that jurors do follow judicial instructions to ignore inadmissible evidence, but other research suggests that jurors do not. Two experiments examined whether jurors were affected by inadmissible evidence. The results revealed that although mock jurors were biased by inadmissible evidence prior to deliberations, the bias was tempered following deliberations. In Experiment 1, post deliberation jurors disregarded incriminating evidence that was ruled inadmissible because of due-process concerns. Experiment 2 replicated these results with less incriminating inadmissible evidence and also revealed that jurors did not accurately gauge the impact that the inadmissible evidence had on their verdicts. Theoretical and judicial policy implications are discussed.     

Rejection sensitivity and the defensive motivational system: insights from the startle response to rejection cues

Rejection sensitivity (RS) is the disposition to anxiously expect, readily perceive, and intensely react to rejection. This study used the startle probe paradigm to test whether the affect-based defensive motivational system is automatically activated by rejection cues in people who are high in RS. Stimuli were representational paintings depicting rejection (by Hopper) and acceptance (by Renoir), as well as nonrepresentational paintings of either negative or positive valence (by Rothko and Miro, respectively). Eyeblink startle magnitude was potentiated in people high in RS when they viewed rejection themes, compared with when they viewed nonrepresentational negative themes. Startle magnitude was not attenuated during viewing of acceptance themes in comparison with nonrepresentational positive themes. Overall, the results provide evidence that for people high in RS, rejection cues automatically activate the defensive motivational system, but acceptance cues do not automatically activate the appetitive motivational system.     

Overlapping neural substrates between intentional and incidental down-regulation of negative emotions

Emotion regulation can be achieved in various ways, but few studies have evaluated the extent to which the neurocognitive substrates of these distinct operations overlap. In the study reported here, functional magnetic resonance imaging (fMRI) was used to measure activity in the amygdala and prefrontal cortex of 10 participants who completed two independent tasks of emotion regulation-reappraisal, measuring intentional emotion regulation, and affect labeling, measuring incidental emotion regulation-with the objective of identifying potential overlap in the neural substrates underlying each task. Analyses focused on a priori regions of interest in the amygdala and inferior frontal gyrus (IFG). For both tasks, fMRI showed decreased amygdala activation during emotion regulation compared with emotion conditions. During reappraisal, this decrease in amygdala activation was accompanied by a proportional decrease in emotional intensity ratings; during affect labeling, the decrease in amygdala activation correlated with self-reported aggression. Importantly, across participants, the magnitude of decrease in amygdala activation during reappraisal correlated with the magnitude of decrease during affect labeling, even though the tasks were administered on separate days, and values indexing amygdala activation during each task were extracted independently of one another. In addition, IFG-amygdala connectivity, assessed via psychophysiological interaction analysis, overlapped between tasks in two regions within the right IFG. The results suggest that the two tasks recruit overlapping regions of prefrontal cortex, resulting in similar reductions in amygdala activation, regardless of the strategy employed. Intentional and incidental forms of emotion regulation, despite their phenomenological differences, may therefore converge on a common neurocognitive pathway.     

Predictors of Depressive Symptoms Among Children Affected by HIV in Rural China: A 3-Year Longitudinal Study

The current study was designed to examine the trend of depression among children affected by HIV (n = 1,221) in rural China over a period of 3 years and to explore baseline psychosocial factors that can predict depressive symptoms at 1- and 2-year follow-ups. Baseline depression score, trusting relationship with caregivers, perceived public stigma against children affected by HIV, and future expectation at baseline positively predicted the 1-year follow-up depression, while children’ self-report health status, self-esteem, and perceived social support negatively predicted depression at 1-year follow-up survey. Depression and self-report health status at baseline significantly predicted depression at the 2-year follow-up. The data in the current study suggested that depressive symptoms were chronic or recurring among some children affected by HIV/AIDS. The findings also underscore the importance of early identification, early intervention, and ongoing counseling for mental health problems among children affected by HIV/AIDS. Future psychological support programs need to target both mental health symptoms and resilient factors that will help these children to cope with adverse life events associated with HIV/AIDS.
