Retrieval processes in fifth graders and adults

This research was concerned with retrieval processes which underlie conceptual clustering. In a free recall task with categorized lists, fifth graders' and adults' retrieval was examined temporally by means of interword response times. List organization and retrieval cue factors were manipulated in order to assess the developmental relevance of an hypothesized three component retrieval model. The results indicated that both age groups used a qualitatively similar retrieval strategy, involving search for and decoding of higher-order memory units. Providing retrieval cues eliminated the category search component, but also increased the likelihood of exhaustive recall attempts under random presentation conditions. The results were discussed in terms of the inter-relationships between storage and retrieval strategies. Age-related differences in retrieval time were attributed to insufficient reorganization during input and failure to attempt to recall all of a category's members.     

THE EFFECTS OF PROMPTING QUESTION-ASKING UPON ON-TASK BEHAVIOR AND READING COMPREHENSION1

This study investigated a teacher-implemented prompting procedure for training students to ask questions. Two special-class (EMR) students who asked no questions were selected as subjects. Baseline data were also collected on reading comprehension and on-task behavior, and these suggested decreasing levels of performance. The results indicated that prompting was effective for initiating question-asking. In addition, increased levels of reading comprehension and on-task behavior were observed.     

Ability evaluation through social comparison

Two experiments were conducted to clarify and extend social comparison theory for abilities. In the first experiment, the hypothesis was supported that people want information about their ability level more when they anticipate making a decision about an action based on the ability than when the decision has already been made. The evaluative need is thus primarily a predecision phenomenon. The second experiment showed that the preference for comparison with similar others predicted by social comparison theory is strongest when those others have had experience utilizing the ability in situations relevant to subjects' decisions.     

The relationship of vocational decidedness and satisfaction with dogmatism and self-esteem

The purpose of this study was to investigate the relationship of levels of vocational decidedness and the satisfaction or dissatisfaction of one's level of vocational decidedness with dogmatism and self-esteem. The results indicated that vocationally decided and undecided subjects represent uniquely different populations on measures of dogmatism and self-esteem.

The roles of contour and luminance distribution in determining perceived centers within shapes

Two sources of visual information that likely could be employed by the perceptual system in locating the centers of bounded shapes—boundary configuration and luminance distribution—have been perfectly confounded in every study thus far aimed at investigating perceived centters. Observers, using either a revolving or stationary x-y plotter, made judgments on the location of centers within either revolving or stationary shapes of both uniform and varied luminance distributions. Results indicate that the location of perceived centers depended predominantly upon boundary contour and was affected by the distribution of luminance within these edges to a much lesser degree.     

Autonomous processes in comprehension: A reply to Marslen-Wilson and Tyler

A criterion which has been proposed for distinguishing minds from computing systems is examined from the point of view of some current work on computer induction.     

Mutual problem-solving skills training for premarital couples: A six-month follow-up

The purpose of the present study was to undertake a six-month follow-up of the communication and problem-solving skill level of those premarital couples trained in the Ridley, Avery, Harrell, Leslie, and Dent (in press) study. Fifty-nine percent of the original sample (14 experimental couples and 18 control couples) were given a behavioral assessment of communication and problem-solving ability six months after training. Results indicated that the experimental group, relative to the control group, had significantly higher pretest to follow-up scores on communication skills and the problem-solving steps. Discussions centered on the implications of skill maintenance over time and possible directions of future research.     

Intrahemispheric differentiation of vowels: Principal component analysis of auditory evoked responses to computer-synthesized vowel sounds

Auditory evoked brain responses (AER) were recorded in response to a series of synthesized vowel sounds which varied in formant bandwidth. Multivariate analyses indicated that changes in AER component structure recorded from different scalp regions over both hemispheres varied as a function of different vowel sounds and formant bandwidth. No interhemispheric differences in scalp AER distributions were noted.     

Interdisciplinary agreement in the diagnosis of headache types

The degree of agreement in independent diagnosis of headache by a neurologist and a clinical psychologist was determined to be 86.4% in a series of 66 consecutive patients. Fifty-five percent of the disagreements were due to the patients' giving different information to the two assessors. This source of disagreement was associated with the patients' having had previous psychiatric treatment.This research was supported in part by Grant NS-15235 from the National Institute of Neurological and Communicative Disorders and Stroke.
