Exposure to Unethical Career Events: Effects on Decision Making,Climate, and Socialization

An implicit goal of many interventions intended to enhance integrity is to minimize peoples' exposure to unethical events. The intent of the present effort was to examine if exposure to unethical practices in the course of one's work is related to ethical decision making. Accordingly, 248 doctoral students in the biological, health, and social sciences were asked to complete a field appropriate measure of ethical decision making. In addition, they were asked to complete measures examining the perceived acceptability of unethical events and a measure examining perceptions of ethical climate. When these criterion measures were correlated with a measure examining the frequency with which they had been exposed to unethical events in their day-to-day work, it was found that event exposure was strongly related to ethical decision making but less strongly related to climate perceptions and perceptions of event acceptability. However, these relationships were moderated by level of experience. The implications of these findings for practices intended to improve ethics are discussed.     

Temporal isolation effects in recognition and serial recall

Recent temporal distinctiveness models of memory predict that temporally isolated items will be recalled better than temporally crowded items. The effect has been found in some tasks (free recall, memory for serial order when report order is unconstrained, running memory span) but not in others (forward serial recall). Such results suggest that the attentional weighting given to a temporal dimension in memory may vary with task demands. Here, we find robust temporal isolation effects in recognition memory (Experiment 1) and a smaller isolation effect in forward serial recall when an open pool of items is used (Experiment 2). Analysis of 26 temporal isolation effects suggests that the phenomenon occurs in a range of tasks but is larger when it is useful to attend to a temporal dimension in memory. The overall pattern of results is taken to favor memory models that rely on multiple weighted dimensions in memory, one of which is temporal.     

BARS and Those Mysterious,Missing Middle Anchors

Purpose  

A contributing reason for the common problem of missing middle anchors on behaviorally anchored rating scales (BARS) is the standard deviation (SD) criterion used in scaling phase. An alternative BARS scaling process is proposed based on the a _wg(1) index of interrater agreement.     

Unimpaired trace classical eyeblink conditioning in Purkinje cell degeneration (pcd) mutant mice

Young adult Purkinje cell degeneration (pcd) mutant mice, with complete loss of cerebellar cortical Purkinje cells, are impaired in delay eyeblink classical conditioning. In the delay paradigm, the conditioned stimulus (CS) overlaps and coterminates with the unconditioned stimulus (US), and the cerebellar cortex supports normal acquisition. The ability of pcd mutant mice to acquire trace eyeblink conditioning in which the CS and US do not overlap has not been explored. Recent evidence suggests that cerebellar cortex may not be necessary for trace eyeblink classical conditioning. Using a 500 ms trace paradigm for which forebrain structures are essential in mice, we assessed the performance of homozygous male pcd mutant mice and their littermates in acquisition and extinction. In contrast to results with delay conditioning, acquisition of trace conditioning was unimpaired in pcd mutant mice. Extinction to the CS alone did not differ between pcd and littermate control mice, and timing of the conditioned response was not altered by the absence of Purkinje cells during acquisition or extinction. The ability of pcd mutant mice to acquire and extinguish trace eyeblink conditioning at levels comparable to controls suggests that the cerebellar cortex is not a critical component of the neural circuitry underlying trace conditioning. Results indicate that the essential neural circuitry for trace eyeblink conditioning involves connectivity that bypasses cerebellar cortex.     

Acute effects of alcohol on memory: Impact of emotional context and serial position

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding.     

The Impact of Feminist Attitudes on the Relation between Racial Awareness and Racial Identity

This study examined the role of liberal and inclusive feminist attitudes in the development of a positive racial identity in a sample of White female undergraduates in the Midwestern United States. Participants (N?=?90) provided self-report data on their racial awareness, liberal and inclusive feminist attitudes, racial identity and demographic information. The main research question was how and to what extent liberal and inclusive feminism influence the relationship between racial awareness and racial identity. Building on conceptual scholarship on identity theory and the intersectionality, results indicated that the relation between racial awareness and racial identity was partially mediated by inclusive feminist attitudes but not by liberal feminist attitudes. The results suggest that a specific type of feminism, which takes into account the experience of race, plays a significant role in our understanding of how White women develop a positive White identity. Results highlight the intersection of race and gender in college student development and have potential implications for administrative responses to student adjustment in increasingly diverse college environments.     

Perfectionism as a Predictor of Post-event Rumination in a Socially Anxious Sample

Socially anxious individuals tend to have elevated levels of perfectionism and engage in excessive rumination following social situations. The present research aimed to examine perfectionism, in both state and trait forms, as a predictor of post-event rumination. Socially anxious students (N = 104) completed measures of trait perfectionism prior to, and state perfectionism following, an anxiety inducing speech task. Post-event rumination was assessed 2 days later. State and trait perfectionism were significant predictors of post-event rumination (2 days later), while controlling for baseline social anxiety, depression and state anxiety. These results support the need to target perfectionism in treatments for social anxiety disorder.     

Self-reflection and feelings of self-worth: When Rosenberg meets Heisenberg

The more people think about their attitude toward some issue, the stronger their attitude becomes. The present research examined whether this strengthening effect also applies to self-evaluative attitudes. In four studies, we had some participants complete a self-evaluation measure before rating their momentary feelings of self-worth (Studies 1, 2, and 4) or implicit self-feelings (Study 3). In all four studies, evaluative self-reflection led low self-esteem participants to feel worse about themselves and high self-esteem participants to feel better about themselves. We did not find this self-esteem polarization effect when more general emotions of happiness and sadness were measured (Study 2) or when participants reflected on non-evaluative aspects of themselves (Study 4). These findings suggest that evaluative self-reflection has different consequences for low self-esteem people than for high self-esteem people, and that order effects in personality research may represent actual changes in self-feelings rather than methodological confounds.     

The Relevance of Age of Onset to the Psychopathology of Social Phobia

The present study aimed to examine the relevance of age of onset to the psychopathology of social phobia using a large clinical sample of 210 patients with social phobia. The two most common periods of onset were during adolescence (ages 14–17) and early childhood (prior to age 10). Structural regression modeling was used to test predictions that early onset social phobia would be associated with greater severity of the disorder, stronger current symptoms of depression and anxiety, greater functional impairment, and more pronounced levels of emotional disorder vulnerabilities (e.g., neuroticism/behavioral inhibition, extraversion, perceptions of control). Logistic regression was used to evaluate relationships between age of onset and the presence of acute and chronic stress at the time of onset. Results showed that earlier age of social phobia onset was associated with stronger current psychopathology, functional impairment, and emotional disorder vulnerabilities, and that later age of onset predicted the presence of an acutely stressful event around the time of disorder emergence. These results are discussed in regard to their clinical implications and congruence with prominent etiological models of the emotional disorders.
