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.     

Does control of the environment enhance the perception of control?

It has been proposed that control over the environment increases the perception of control, thereby enhancing motivation. Revesman and Perlmuter (1981) found that when subjects were permitted to choose response terms to be learned on a paired-associate task, decision latencies were faster if the announcement of the desired option caused the screen upon which materials were printed to go blank. On the basis of the results of the present experiment, it was concluded that control of the environment does result in faster decision latencies, but that this effect occurs despite a decrease in the perception of control.     

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.
