The effect of overtraining on behavioral contrast and the peak-shift

Following initial discrimination training between two wavelength stimuli and a subsequent generalization test to the wavelength dimension, Group 1 was “overtrained” for 105 days on the original discrimination. Group 2 was “overtrained” with the original positive stimulus and a new negative stimulus, a white line. Group 3 was “overtrained” with the original negative stimulus and a new positive stimulus, the white line. Each 15 days of extended training were followed by a wavelength generalization test similar to the first test. The results suggest that there is no consistent relationship between the response rate in positive stimulus immediately before the generalization test and whether or not a peak shift occurs during the test.     

The effect of the Müller-Lyer illusion on the planning and control of manual aiming movements

Two experiments used Müller-Lyer stimuli to test the predictions of the planning-control model (S. Glover, 2002) for aiming movements. In Experiment 1, participants aimed to stimuli that either remained the same or changed upon movement initiation. Experiment 2 was identical except that the duration of visual feedback for online control was manipulated. The authors found that the figures visible during movement planning and online control had additive effects on endpoint bias, even when participants had ample time to use visual feedback to modify their movements (Experiment 2). These findings are problematic not only for the planning-control model but also for A. D. Milner and M. A. Goodale's (1995) two visual system explanation of illusory bias. Although our results are consistent with the idea that a single representation is used for perception, movement planning, and online control (e.g., V. H. Franz, 2001), other work from our laboratory and elsewhere suggests that the manner in which space is coded depends on constraints associated with the specific task, such as the visual cues available to the performer.     

Gender differences in early risk factors for adolescent depression among low-income urban children

One component of a model by Nolen-Hoeksema and Girgus, who propose that risk factors for adolescent depression are more common in girls than in boys during childhood, was tested with 85 low-income, urban, African American and Latino kindergarten through fourth grade children who completed inventories of depression, stress, attributional style, gender role, and body image. Endorsing two of three predicted risk factors, girls reported slightly poorer body image and identified more strongly with a feminine gender role. Boys, however, reported a more negative attributional style. Feminine gender role was not associated with body image or negative attributional style. The applicability of the proposed model to a low-income, ethnic minority, urban population is discussed.     

Morality,politics, and contingency

The influential realist thesis that politics and morals are distinct and mutually exclusive spheres of interest is one that has been challenged within the tradition of analytic moral and political theory. Over the last 50 years, several notable liberal analytic philosophers, including Isaiah Berlin, Stuart Hampshire, and Thomas Nagel, have argued that not only is politics not separate from and inimical to ethics but that there exists such a thing as political morality. This article contends that while the notion of political morality may make more sense of what is regarded as a central and troubling problem of politics, it also forces us to confront the more fundamental challenge of the radical contingency of our moral and political predicament. Whether analytic political theory is capable of producing a convincing response to the latter challenge remains precariously unclear.     

Irrational beliefs and psychosomatic disorders

Irrational beliefs were related to psychosomatic disorders in an adult sample of 57 male and 68 female psychotherapy clients and 62 male and 38 female adult nonclients. The client and nonclient samples differed markedly in a number of ways, but nevertheless, in both samples those with relatively high frequencies of psychosomatic disorders scored as more irrational on 7 of the 10 scales of the Jones Irrational Beliefs Test (IBT) compared to those with relatively low frequencies of psychosomatic disorders. Hierarchical multiple regression analyses found Anxious Overconcern (AO) to account for 31.7% of the variance in the psychosomatic illness scores for the nonclient sample and 10.8% of the variance for the client sample. Subgroups within each sample formed on the basis of their AO scores (a B-level variable in RET theory) were subsequently found to be significantly different on the C-level variables of anxiety and psychosomatic disorders. It is argued that causal connections are implied and that the results are better understood in a monistic mind-body-unit conceptualization of the human organism.Paul J. Woods, Ph.

The dynamic nature of the stress appraisal process and the infusion of affect

Very little is known about the process in which people reappraise a stressful environment or the factors that may influence this process. In the current study, we address the several limitations to previous research regarding stress reappraisals and explore the role of affect on this process. A total of 320 participants (mean age = 20 years, 60% male) completed an increasingly demanding team-based coordination task. Mood and stress appraisals were assessed at three time points using self-report surveys during four different waves of data collection. The longitudinal design enabled us to assess primary and secondary reappraisals (change in appraisals during the experiment), task-irrelevant affect (affect assessed prior to experiment participation), and task-relevant affect (change in affect experienced during the experiment). Guided by the Transactional Theory of Stress, we argue that the relationship between primary reappraisal and secondary reappraisal is an accurate representation of a dynamic stress appraisal process. We found that participants were more likely to engage in the stress appraisal process when they experienced less task-irrelevant positive affect and greater task-relevant positive affect. Both task-irrelevant and task-relevant negative affect were not found to influence the stress appraisal process.     

Memory for child sexual abuse information: Simulated memory error and individual differences

Building on the simulated-amnesia work of Christianson and Bylin (Applied Cognitive Psychology, 13, 495–511, 1999), the present research introduces a new paradigm for the scientific study of memory of childhood sexual abuse information. In Session 1, participants mentally took the part of an abuse victim as they read an account of the sexual assault of a 7-year-old. After reading the narrative, participants were randomly assigned to one of four experimental conditions: They (1) rehearsed the story truthfully (truth group), (2) left out the abuse details of the story (omission group), (3) lied about the abuse details to indicate that no abuse had occurred (commission group), or (4) did not recall the story during Session 1 (no-rehearsal group). One week later, participants returned for Session 2 and were asked to truthfully recall the narrative. The results indicated that, relative to truthful recall, untruthful recall or no rehearsal at Session 1 adversely affected memory performance at Session 2. However, untruthful recall resulted in better memory than did no rehearsal. Moreover, gender, PTSD symptoms, depression, adult attachment, and sexual abuse history significantly predicted memory for the childhood sexual abuse scenario. Implications for theory and application are discussed.     

The Influence of Cue Reliability and Cue Representation on Spatial Reorientation in Young Children

Previous studies of children's reorientation have focused on cue representation (e.g., whether cues are geometric) as a predictor of performance but have not addressed cue reliability (the regularity of the relation between a given cue and an outcome) as a predictor of performance. Here we address both factors within the same series of experiments. We show that for 18- to 30-month-olds, high cue reliability is a dominant factor positively affecting reorientation behavior. Under conditions of high cue reliability, children use both scalar and nonscalar cues for successful reorientation. By contrast, under conditions of low cue reliability, children successfully use scalar cues but not nonscalar cues, suggesting that mapping of left–right visual features onto a viewer-centric sense of left and right is facilitated when features themselves are ordered. More generally, we suggest that cue-driven spatial reorientation is best understood as part of a broader system capable of flexibly linking stimuli and responses.     

Sense of coherence as a protective factor for psychological distress among gay men: a prospective cohort study

Gay men face a greater risk of psychological distress than heterosexual men, yet research on protective factors among gay men has been limited. This prospective cohort study investigated whether a sense of coherence (SOC), as a form of coping, helps to protect against psychological distress among middle-aged and older gay men. A nationwide online survey was conducted among a baseline sample of 1135 Australian gay-identified men aged 40 years and older, with a follow-up survey 12 months later. SOC was measured using the 13-item SOC Scale. Psychological distress was measured using the K10 Psychological Distress Scale. Hierarchical regressions were conducted, with analyses controlling for several potential risk factors for distress. Over half of participants had moderate or high psychological distress. However, baseline distress was significantly lower among those with stronger baseline SOC. In addition, baseline SOC significantly predicted distress 12 months later. This predictive effect of SOC was independent of baseline distress levels and occurred despite a strong correlation between baseline and follow-up distress. With SOC appearing to be a protective factor, strategies among middle-aged and older gay men that strengthen SOC may assist in the prevention and treatment of anxiety and other psychological distress in this vulnerable population.
