The role of perceptual and semantic elaboration in high- and low-imagery sentence recall

Sentence imagery effects in recall are predicted by both perceptual and semantic elaboration models. The former attributes superior recall of high-imagery sentences to the addition of perceptual network components to an existing semantic network; the latter claims that additions of semantic components are involved. In order to identify the responsible components, free associates were generated to otherwise similar high- and low-imagery sentences in a short-term memory task. In accordance with the perceptual elaboration model, associates differed in rated imagery, but not in number. In a second study, the causal role of perceptual elaboration in recall was investigated by using high- and low-imagery sentence associates as recall cues. Differential effects of cue imagery were found for high-imagery sentences, indicating that perceptual codes are in part responsible for superior high-imagery sentence recall. Evidence is presented that perceptual and semantic network components are involved in a processing trade-off, and the adequacy of present network models to explain it is discussed.     

Vicarious and operant experiences in the etiology of illness behavior: A replication with healthy individuals

The purpose of the present investigation was to replicate a previous study of diabetic patients on the role of parental modeling in the etiology of illness behavior. A random sample of healthy individuals were assigned to an avoidant model (AM) (i.e. parent reported to have avoided work. chores etc. when ill) or non-avoidant model (NAM) group. Subjects subsequently provided retrospective and current information concerning their illness-behavior experiences. The results indicated that individuals with an AM reported more responsibility avoidance when ill currently and as a child compared to the NAM subjects. Additionally. AM subjects reported receiving more positive reinforcement for current illness compared to NAM subjects. It was concluded that the process by which individuals learn to respond to illness may be similar in healthy and chronically-ill individuals but that positive reinforcement for illness may be more likely to be received by healthy individuals during acute illness than by chronically-ill individuals. The present study provides further preliminary support for the learningtheory model of illness behavior.     

Children's strategies for controlling affective responses to aversive social experience

It was hypothesized that one mechanism of self-control that children develop is the strategic capacity to select the experiences they encounter. This hypothesis led to the prediction that children would deal with certain aversive social experiences by seeking out or taking advantage of opportunities for nurturant experiences. Young children were exposed to an aversive social experience in which they received less nurturance than a peer, a positive experience in which they received more nurturance, or a neutral experience in which nurturance was equal. Subsequently, an opportunity was provided for children to control the length of time they watched a highly nurturant television program. As predicted, boys experiencing an aversive social encounter increased the length of time they exposed themselves to the nurturant television show, and their level of reduced positive affect was related to how long they watched the nurturant content, further supporting the interpretation that they did so in response to their own affective state. Girls did not adopt the strategy of self-exposure to nurturant television but did appear to engage in self-distraction during the aversive social experience. Despite the apparent use of control strategies, there was no indication that these strategies were effective for the amelioration of reduced positive affect resulting from the aversive social experience. Discussion focuses on the sex differences observed in the adoption of strategic behavior and factors contributing to the ineffectiveness of the control strategies. A general model is proposed for personal and environmental factors requisite for the selection, employment, and effectiveness of strategies to control experiences and their affective consequences.     

Voice Identification Over the Telephone1

Following a telephone survey investigating attitudes toward police and frequency of personal victimization. 177 citizens between the ages of 18 and 88 years participated without forewarning in a field study on telephone voice identification. Identification accuracy (hits) improved with longer conversation durations (an average duration of 7.8 min compared to conversation durations of 3.2 min and 4.3 min. on average), but the false alarm rate also reliably increased with longer durations in a target-present lineup. False alarms were consistently high (overall M= .48) in the target-absent lineup. No significant differences were found in hit scores or false alarm scores over a two to three day retention interval. No significant correlation was found between confidence scores and accuracy of performance on the target-present lineup (r= .10). but a significant correlation (r= 36) was found on the target-absent lineup.     

The knowledge and use of quantitative research by pastoral counselors

This study investigated the degree of training, experience and interest in quantitative research among pastoral counselors. It was found that a little over half of the subjects had had at least one statistics course and thought that research was valuable. However, less than 6% had ever published research and only one subject (less than 1%) had published more than two quantitative articles. This suggests there is a research vacuum in the field of pastoral counseling. There is no scientific core of scholars publishing a systematic program of research. Recommendations for ways to involve pastoral counselors more actively in research are made.New Perspectives, Owings Mills, MD.
