Inhibition of return in static and dynamic displays

Inhibition of return (IOR) causes people to be slower to return their attention to a recently attended object (object-based IOR) or location (location-based IOR). In attempts to separately measure the two components, moving stimuli have been used that permit the dissociation of the attended object from its location when it was attended. The implicit assumption has been that both object- and locationbased components of IOR will operate whenever the cued object and cued location are identical. We show here that although this assumption may be true in a static display, it appears to be unwarranted when moving stimuli are involved: Very little IOR is observed when a cued object moves away from, and then subsequently returns to, its initial location. Thus, the processes that underlie IOR operate very differently in static versus dynamic scenes.     

Stress and cytokine-elicited neuroendocrine and neurotransmitter sensitization: implications for depressive illness

Stressful events, by their effects on neurotransmitter and neuroendocrine processes, are thought to favor the development or exacerbation of depressive illness. In as much as immunological challenge, may provoke stressor-like neuroendocrine and central neurochemical changes, the view was offered that immune activation essentially acts like a stressor and may contribute to the evolution of affective illness. In this respect, viral and bacterial infections appear to influence behavioral/metabolic (e.g. fever, anorexia, somnolence) and neurotransmitter functioning through the release of cytokines, which act as messengers between the immune system and brain. The present report provides a brief overview of the neurochemical consequences of proinflammatory cytokine treatments, particularly the actions of interleukin (IL)-1beta and tumor necrosis factor-alpha. As well, synergy with psychogenic and neurogenic stressors are described, as are data showing that cytokines, like stressors, may have time-dependent proactive (sensitization) effects, so that reexposure to the treatments greatly augments hypothalamic-pituitary-adrenal activity, as well as central neurochemical changes. Indeed, the neurotransmitter alterations are not restricted to hypothalamic nuclei, but occur in several extrahypothalamic sites, including various limbic regions. It is suggested that by virtue of these neurochemical changes, cytokines may have both immediate and proactive effects on mood states.     

Argumentum Ex Divinatione: Divination and Civic Argument in the Ancient World

This argument explores transcultural commonalities among civic arguments from divination in global antiquity. In the ancient world, proponents engaged in kisceral arguments deriving from divinatory signs: arguments ex divinatione regarding prospective civic action. Under ideal circumstances, their aim was to help insure that the collective action of human political organizations was aligned with the natural synchrony of the cosmos. Thus, civic arguments from divination were employed to anticipate the future’s course based on the signs the system produced holistically. In ancient Mesopotamia, China, and Rome, divination was employed as a tool for aligning the order of human society to that of a conception of metaphysical or cosmic order. By comparing these argumentative examples and rationales, we see a broader context for the way in which humans made arguments toward political futurity outside more conventional syllogistic formulations concerning causation. Rather, the argumentative strategies of many ancient cultures embraced an understanding of the future as the logical outcome of a holistic dynamism in kairotic time.

     

The center and range of the probability interval as factors affecting ambiguity preferences

Ambiguous decision situations are characterized as having probabilities that are uncertain. The uncertainty is due to the common, real-world deficiency of information about the process by which the outcomes are determined. Thirty lotteries having uncertain probabilities were constructed by varying the centers and the ranges of the intervals within which the imprecise probabilities of winning could lie. Pairs of the lotteries were presented as choice alternatives to subjects, with each pair having lotteries with the same interval center but differing interval ranges. Ambiguity avoidance, the selection of the less ambiguous option, was found to increase with the interval center C, with ambiguity indifference occurring for values of C ? 0.40. No evidence of ambiguity seeking as the prevalent behavior was obtained. Ambiguity avoidance did not significantly increase with the interval range R, but an interaction effect between C and the ranges R₁ and R₂ of the choice pair was obtained. This effect of the ranges could not be described simply by knowledge of the difference R₁ ? R₂; knowledge of both individual values was necessary. The theoretical implications of these results are discussed.     

The Perceived Stress Scale: Factor structure and relation to depression symptoms in a psychiatric sample

The present study sought to examine the factor structure and psychometric properties of the Perceived Stress Scale (PSS) when administered to psychiatric patients. We also examined predictive validity of the PSS by assessing the association between the Perceived Stress Scale and the Beck Depression Inventory. A heterogeneous sample of 96 psychiatric patients (48 men, 48 women) completed the Perceived Stress Scale (PSS) and the Beck Depression Inventory. Factor analysis of the PSS established that the scale consisted of two factors. The first factor was comprised primarily of items reflecting adaptational symptoms. In contrast, the second factor consisted of items reflecting coping ability. Both factors had an adequate degree of internal consistency. Finally, a series of regression analyses predicting depression found that both factors accounted for unique variance in depression scores in women, but only the first factor accounted for unique variance in men. It is concluded that the PSS is a multidimensional and internally consistent measure of perceived stress.This research was supported by Grant 410-91-1690 from the social sciences and Humanities Research Council of Canada as well as by grants from the Research and Program Evaluation Committee Brockville Psychiatric Hospital.     

The Impact of Brief Mindfulness Training on Postevent Processing Among Individuals With Clinically Elevated Social Anxiety

Postevent processing (PEP), the engagement in detailed and repetitive self-focused review of one’s performance in social situations, is theorized to maintain pathological social anxiety. However, little is known about interventions that may impact this maintenance factor. The current study examined the impact of brief mindfulness training (BMT) on PEP among socially anxious individuals. There were 77 participants (75.32% female, 63.64% non-Hispanic/Latinx White) with clinically elevated social anxiety who attended one appointment in the laboratory during which they were randomized to receive a brief mindfulness-based training (n = 37) or no training (i.e., thinking as usual control group; n = 40). After the training period, participants underwent a 3-minute social anxiety induction task, after which they were instructed to apply their thinking strategy. Participants were then asked to complete 2 weeks of daily online surveys that included a PEP induction task, instructions to use their thinking strategy following PEP induction, and a measure of state PEP. Individuals in the BMT condition reported a significant reduction in state anxiety posttraining compared to individuals in the control condition. Conditions did not differ on state PEP after the social anxiety induction task. However, compared to those in the control condition, participants in the BMT condition reported significantly greater decreases in state PEP over the 14-day follow-up period. Thus, this brief mindfulness-based strategy may be useful for individuals with clinically elevated social anxiety who engage in PEP, a cognitive vulnerability factor implicated in the maintenance of social anxiety.     

A Revision of the Multicultural Counseling Awareness Scale

This article reports the results of 2 studies designed to test and revise the Multicultural Counseling Awareness Scale (J. G. Ponterotto et al., 1996). Collective results support the 2‐factor extraction (Knowledge and Awareness) as the best fit model and provide initial indices of validity and internal consistency reliability for the newly titled Multicultural Counseling Knowledge and Awareness Scale. Este artículo informa los resultados de 2 estudios diseñados para probar y revisar la Escala de Conciencia de Consejería Multicultural (J. G. Ponterotto et al., 1996). Los resultados colectivos sostienen la extracción de 2 factures (el Conocimiento y la Conciencia) como el mejor modelo y proporcionan los índices iniciales de validez y fiabilidad de la consistencia interna para la nuevamente titulada Escala de Conocimiento y Conciencia de Consejería Multicultural.     

White Racial Identity Attitudes and the Ego Defense Mechanisms Used by White Counselor Trainees in Racially Provocative Counseling Situations

This exploratory study examined the relationship between racial identity attitudes and the use of ego defense mechanisms by White counselor trainees during cross‐racial counseling and supervision dyads. The sample consisted of 145 White counselor trainees enrolled in both master's and doctoral programs at 2 small private universities located in the northeastern United States. Results indicated that White counselor trainees at less mature statuses of racial identity attitudes relied on more primitive ego defenses to manage the anxiety experienced during racially provocative counseling and supervision dyads. Implications for counseling and counselor training are discussed in the context of the study's findings.
