Teachers’ perceived time pressure,emotional exhaustion and the role of social support from the school principal

Social Psychology of Education - Many teachers experience high levels of work-related strain due to time pressure, which over time can lead to various health problems, such as emotional exhaustion....     

Recent research on the relative efficiency of speaker and listener instruction for children with autism spectrum disorder

The traditional recommendation for sequencing speaker and listener instruction has been to teach listener skills prior to teaching speaker skills. In a review of the research literature prior to 2011, Petursdottir and Carr (2011) concluded that research did not support this recommendation. We reviewed the most recent research on the efficiency of skill acquisition during speaker and listener instruction and found similar results to Petursdottir and Carr. Recommendations for future research and practice are provided.     

Acquired equivalence and distinctiveness of cues: I. Exploring a neural network approach

Rats were placed in 4 contexts (A, B, C, D) where they received 2 auditory stimuli (X, Y); in A and B, presentations of X were paired with food and those of Y were not, and in C and D, Y was paired with food and X was not. Rats then received combinations of contexts that had provided congruent (AB, CD) or incongruent (AD, CB) information about X and Y's relationship to food. Responding was more variable during congruent than incongruent trials (Experiment 1) and was systematically increased and decreased during congruent (relative to incongruent) trials by the presentation of food or no food, respectively (Experiment 2). These results support a connectionist approach to acquired changes in stimulus distinctiveness.     

Acquired equivalence and distinctiveness of cues: II. Neural manipulations and their implications

Neural manipulations were used to examine the mechanisms that underlie the acquired equivalence and distinctiveness of cues in rats. Control rats and those with excitotoxic lesions of either the hippocampus (HPC) or entorhinal cortex (EC) acquired the following conditional discrimination: In Contexts A and B, Stimulus X-->food and Stimulus Y-->no food, and in Contexts C and D, Y-->food and X-->no food. Rats then received many food pellets in A but not in C. After this treatment, control rats showed more magazine activity in B than in D--an acquired equivalence-distinctiveness effect. This effect was also evident in HPC rats but not in EC rats. These results indicate that changes in stimulus distinctiveness are dissociable from the process of conditional learning.     

The detection of feigned uncoached and coached posttraumatic stress disorder with the MMPI-2 in a sample of workplace accident victims

In this study research participants completed the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) under standard instructions and then were asked to fake posttraumatic stress disorder (PTSD) when completing the MMPI-2 for a 2nd time in 1 of 4 conditions with different instructions on how to fake PTSD: (a) uncoached, (b) coached about PTSD symptom information, (c) coached about MMPI-2 validity scales, or (d) coached about both symptoms and validity scales. These MMPI-2 protocols were then compared with protocols of claimants with workplace accident-related PTSD. Participants given information about the validity scales were the most successful in avoiding detection as faking. The family of F scales (i.e., F, FB, FP), particularly FP, produced consistently high rates of positive and negative predictive power.     

Choosing the path to bargaining power: an empirical comparison of BATNAs and contributions in negotiation

Although the negotiations literature identifies a variety of approaches for improving one's power position, the relative benefits of these approaches remain largely unexplored. The empirical study presented in this article begins to address this issue by examining how the size of the bargaining zone affects the relative benefit of an advantage in one's BATNA (i.e., having a better alternative than one's counterpart) versus contribution (i.e., contributing more to the relationship than one's counterpart) for negotiator performance. Results indicate that whereas BATNAs exerted a stronger effect on resource allocations than contributions when the bargaining zone was small, an advantage in contributions exerted a stronger effect on resource allocations than BATNAs when the bargaining zone was large. These findings provide needed insight and supporting evidence for how to alter one's power relationship in negotiation.     

Aggression and self-esteem: a diary study of children's reactivity to negative interpersonal events

The study employs a daily diary design to assess self-esteem reactivity and its association with children's aggressive behavior. We test the hypothesis that the self-esteem of aggressive children will be more reactive to negative interpersonal events than the self-esteem of nonaggressive children. Results provide partial support for the aggression/reactivity hypothesis. Aggressive children's self-esteem was more reactive to negative peer events but less reactive to negative adult events than the self-esteem of less aggressive children. These findings are discussed in relation to the experimental literature relating self-esteem instability and ego-threat to aggression and in relation to the extensive body of research on childhood aggression. Intervention implications are also considered.     

Age and regulatory focus determine preferences for health-related role models

The authors hypothesized that the effectiveness of role models varies across the adult life span because of differences in health-related regulatory orientations. Because young adults have strong health-related promotion orientations, they should be motivated by positive models who illustrate the benefits of good health. Because older adults have more balanced health-related promotion and prevention orientations, they should be motivated not only by positive models but also by negative models who illustrate the costs of poor health. Results indicated that both young and older adults perceived positive models to be motivating, but older adults found negative models to be more motivating than did young adults. Age differences in responses to negative models were partially mediated by differences in health-related prevention orientation.
