Facilitation of retention by white noise.

Second and fifth grade subjects were given three verbal tasks: serial, free recall, or paired-associate learning. Retention tests were administered immediately after the acquisition phase or following a long delay. Half the subjects were exposed to a 2-min period of bursts of white noise (arousal) immediately prior to the retention test. The finding of primary interest was that white noise produced substantial improvement in performance relative to a control condition. This effect may be more pronounced for long-term memory than for short-term memory. Although older children exhibited better long-term memory than younger subjects, no interaction of age with arousal condition was observed.     

Eleven-year career stability and change as reflected in Project Talent data through the Flanagan,Holland, and Roe occupational classification systems

The vocational psychologist seeks classifications of occupations which maximize career stability as occupations change from time to time in the life. This study investigates the extent of career stability and the patterns of career change which have occurred in the lives of Project TALENT twelfth grade students in the 11 yr elapsing since they were tested. “Career” plans in the last year of high school and at 1, 5, and 11 yr after testing were classified by the Flanagan, Holland, and Roe occupational classification systems in order to study the career stability and patterning within each system and to contrast both among systems. Career stability proved to be about the same in all three classification systems but decreased in all cases as the interval over which it was measured increased. Career stability increased as subjects grew older, proving to be the greatest from 5 to 11 yr after high school. Patterns of change mildly conformed to the circular patterns claimed by Holland and Roe for their systems and the linear pattern hypothesized for the Flanagan system. Generally, the direction of “career” flow was away from intellectual careers to careers in business and sales but each system had unique results as well.     

The actual and retrospective-occupational self-concept dimensions of retired educators

A 20-item adjective checklist was used by 118 retired educators to describe their actual and retrospective-occupational self-concepts. The men made their retrospective ratings for middle-aged and preretired occupational roles. The intercorrelations among the self-concept ratings were multiple-set factor analyzed, and seven common dimensions were identified: (1) stability, (2) conventionality, (3) independence, (4) practicality, (5) status, (6) confidence, and (7) cleverness. The results suggested that the retired educators had used the same dimensions in describing their actual and retrospective-occupational self-concepts. The percentages of variance contributed by the dimensions within the self-concept structures were also reported and discussed within the framework of career development.     

Social isolation as a punishment procedure: a controlled study

Contingent social isolation was investigated as a punishment procedure for the disruptive behavior of emotionally disturbed children in a classroom setting. The methodological limitations of previous studies were outlined, and alternatives adopted. Within a reversal and multiple baseline design, contingent social isolation was found to be an effective and relatively specific punisher. By introducing a new observation procedure, “pseudo-timeout”, it was determined that the punishing effect of social isolation was not attributable to observation artifact. A means for resolving the terminological confusion in the present use of timeout and social isolation was recommended.     

The development of memory structure as reflected by semantic-priming effects

This study was designed to investigate the development of knowledge about categorical and associative relationships as reflected by the presence or absence of semantic priming effects. Kindergarteners and second-graders were shown pairs of pictures, one picture at a time, and asked to name each picture as rapidly and accurately as possible. Picture pairs were of four types which reflected the factorial combination of associative relatedness (high and low) with categorial relatedness (high and low). An analysis of naming times revealed a significant main effect of associative relatedness, i.e., second pictures or “target” pictures in high-associative pairs were named faster than those in low-associative pairs. This reduction in naming latency, or priming effect, was independent of developmental level. However, the effects of category relatedness varied with developmental level, i.e., target pictures in high-categorical pairs were named significantly faster than those in low pairs by second-graders, but not by kindergarteners. These findings are discussed in terms of previous estimates of children's semantic competence.     

The component awareness and accuracy of dual- and single-jointed actions

The accuracy with which people execute wrist and elbow movements were measured using three main conditions: (i) single-jointed (wrist or elbow) movements to targets, (ii) dual-jointed (wrist and elbow) movements to targets, and (iii) components of dual-jointed movements to targets, when the task for the subject was to perform the elbow or wrist constituent of the action in isolation, without displacing the second joint. Elbow precision was significantly worse under component than dual conditions, which is compatible with the notion that wrist and elbow activity are conjugately, rather than independently, programmed when a dual-jointed action is performed. The pattern of wrist accuracy was divergent, but possible reasons for this were discussed. In all cases, error was measured in terms of deviation from perfect posture; using this index, the hypothesis that incorporating more moving joints into an action serves to increase movement complexity and jeopardise precision was tested, but the results were ambiguous. Discussion also centered on the problems of using performance data to infer changes in motor programming, and the need for rigorous conceptualisation and research in this area.     

A disfluency descriptor digest for clinical use

A clinical form to be used in identifying which of a set of fluency eliciting techniques might be used most advantageously in therapy with individual stutterers is described.     

A stochastic model for paired comparisons of social stimuli

A stochastic model for paired comparisons of multiattribute social stimuli is proposed where one objective is to find the relative importance of the attributes for a judge. The model can be conceived as a special strict binary utility model, i.e., a BTL-model, and is related to of the stimuli are linear combinations of functions of the attributes of the stimuli. The model neither assumes that the functions are fixed in advance nor that different judges have the same set of functions. The choice among such functions, however, is admitted only within a finite scope. Within the framework of exponential families, maximum likelihood estimators and tests are derived and applied to data coming from two psychological experiments.     

Understanding and appreciating metaphors

We consider three theories that have dominated discussions of metaphor. One view is that metaphors make comparisons, the basis for the comparison being the features (or categories) that the terms of the metaphor share. The second view is that metaphors involve an anomaly. The third view is that metaphors are ‘interactive’, producing a new way of seeing the terms. We propose a new theory—the domains-interaction view—that draws on elements of all three earlier views, but borrows especially from the interaction view. We consider the implications of our theory for three questions: What are metaphors? How are they understood? What makes a good metaphor? We argue that metaphors correlate two systems of concepts from different domains. The best metaphors involve two diverse domains (more distance between domains making for better metaphors) and close correspondence between the terms within those domains. We call the degree of correspondence within-domain similarity. Metaphors are interpreted in several stages: the terms of the metaphor are encoded; the domains involved are inferred; the structures to be seen as parallel are found; the correspondences between these structures are ‘mapped’ or constructed; the terms of the metaphor are compared. If the terms are not seen to match or occupy analogous roles in their different domains, then the metaphor may be reinterpreted. The evidence on all this is tentative but supports our view. We review two studies (Tourangeau and Sternberg, 1981) that support the hypothesis that distance within domain relates negatively to aptness, whereas distance between domains relates positively. Several studies on comprehension tend to disconfirm the comparison theory's notion that the tenor and vehicle necessarily share features. Tenor and vehicle also appear to have asymmetrical roles in the interpretive process.
