Traits, states, and attentional gates: temperament and threat relevance as predictors of attentional bias to social threat

This study investigated the influence of situational and dispositional factors on attentional biases toward social threat, and the impact of these attentional biases on distress in a sample of adolescents. The results suggest greater biases for personally relevant threat cues, as individuals reporting high social stress were vigilant to subliminal social threat cues, but not physical threat cues, and those reporting low social stress showed no attentional biases. Individual differences in fearful temperament and attentional control interacted to influence attentional biases, with fearful temperament predicting biases to supraliminal social threat only for individuals with poor attentional control. Multivariate analyses exploring relations between attentional biases for social threat and symptoms of anxiety and depression revealed that attentional biases alone were rarely related to symptoms. However, biases did interact with social stress, fearful temperament, and attentional control to predict distress. The results are discussed in terms of automatic and effortful cognitive mechanisms underlying threat cue processing.     

VIDEO MODELING TO TRAIN STAFF TO IMPLEMENT DISCRETE‐TRIAL INSTRUCTION

Three new direct‐service staff participated in a program that used a video model to train target skills needed to conduct a discrete‐trial session. Percentage accuracy in completing a discrete‐trial teaching session was evaluated using a multiple baseline design across participants. During baseline, performances ranged from a mean of 12% to 63% accuracy. During video modeling, there was an immediate increase in accuracy to a mean of 98%, 85%, and 94% for each participant. Performance during maintenance and generalization probes remained at high levels. Results suggest that video modeling can be an effective technique to train staff to conduct discrete‐trial sessions.

The Effects on Layoff Survivors of Their Fellow Survivors' Reactions1

A multimethod series of studies examined factors that moderate the effects on layoff survivors of their fellow survivors' reactions. Studies 1 and 2 showed that survivors' work performance was more influenced by the reactions of fellow survivors who were relatively attractive. Study 3 revealed that survivors' work performance and turnover intention were more positively related to the reactions of relatively attractive fellow survivors, but only when the survivors had relatively little communication with their fellow survivors about the layoff; among those who communicated a great deal with fellow survivors about the layoff, work performance, and turnover intention were positively related to their fellow survivors' reactions, regardless of the attractiveness of their fellow survivors. The discussion focuses on theoretical and practical implications, limitations of the studies, and areas for further research.     

The Student Guided Functional Assessment Interview: An Analysis of Student and Teacher Agreement

Functional assessment strategies are used to guide the treatment of problem behavior with individuals who have severe disabilities. Also, researchers have extended functional assessment applications to individuals with emotional and behavioral disabilities. One such extension is the use of students as informants in the functional assessment process. The present study assessed an interview tool designed to elicit information directly from students regarding their problem behaviors. We examined agreement between students and their teachers. Results showed high agreement on the causes and functions of problem behavior with mixed agreement on support plan recommendations.     

Perceived ethicality of guided imagery in rape research

In our first study, undergraduate students (30 men, 30 women) evaluated the ethical acceptability of two previously published studies that used guided imagery in rape situations. In one, women imagined themselves as rape victims; in the other, men imagined themselves as rapists. Most students rated the research acceptable, but there was a significant interaction (p less than .05): Women found the study of women as victim less ethical, and men found the study of men as rapist less ethical. In our second study, 30 noncollege women evaluated the research on women as rape victims. After reading the scenario, none of these women said they would have agreed to participate or thought the research was ethically acceptable. We discuss issues of informed consent, demands of the research situation, and potential benefits and risks.     

What makes targets redundant?

Two letter-classification experiments that investigated target-redundancy effects on reaction time (RT) were conducted. Both experiments were replicated with choice reaction time (CRT) and go/no-go (GNG) procedures. In each experiment, there were two single-target conditions, one with a noise letter and one without. In one experiment, the letter classes were two letters that could be of either case. In the second experiment, each class consisted of two different capital letters. In both experiments, there were two redundant-targets conditions, one with identical targets and one with the different members of a class. In both of the GNG experiments, redundancy gains were obtained comparing the different-targets condition with the no-noise, single-target condition. Redundant stimuli are ones that lead to the same response. Visually different stimuli may be processed in parallel and jointly activate a response. GNG procedures are more sensitive than CRT in the investigation of redundancy effects.     

Tacit knowledge and the effect of pattern configuration on mental scanning

Two opposing hypotheses are that estimated distances may be used to predict scanning times in mental scanning experiments (Mitchell & Richman, 1980; Pylyshyn, 1981) and that scanning times may be used to estimate distances on maps (Thorndyke, 1981). We tested these hypotheses by having people both estimate lengths and mentally scan diagonal lines, spirals, and mazes. There were large and consistent differences in the rate of scanning the three configurations, regardless of whether people scanned percepts or images. These differences could not be accounted for by differences in length estimates or by people’s tacit knowledge of their scanning rates. We propose that people actually do mental scanning in a mental scanning task rather than use length estimates to generate scanning time and that they do not rely on scanning times to estimate length in a length estimation task.
