Getting started with multimedia

This paper provides an overview of the symposium “Multimedia in Instruction” by addressing four basic issues: What does multimedia mean? Does it have advantages beyond traditional means of presentations in a classroom? What equipment does one need? What software are available for psychology instruction? Although multimedia represents a revolutionary technology, its application to instruction is an extension of computer-assisted instruction.     

A comparison of “traditional” and “atypical” workers: Demographic,behavioral, and attitudinal differences

Differences among full-time (n=1066), part-time (n=132), and moonlighting employees (n=153) in a variety of occupations were examined. Moonlighters as compared to full-timers were younger, more frequently male, perceived less educational fit with their main jobs, and were primary wage earners. Full-timers as compared to part-timers were more frequently male, married, and primary wage earners. Part-timers had the greatest turnover, but no differences were detected for other withdrawal behaviors. Part-timers were more satisified with working conditions but were less satisfied with extrinsic rewards and life in general. Moonlighters expressed a stronger work ethic and placed less importance on working conditions.A version of this paper was presented at the 1991 Meetings of the Southwest Division of the Academy of Management in Houston, TX.     

BRIEF HIERARCHICAL ASSESSMENT OF POTENTIAL TREATMENT COMPONENTS WITH CHILDREN IN AN OUTPATIENT CLINIC

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components was conducted to identify variables that controlled the children's appropriate behavior. Experimental control via a brief reversal was achieved for 6 of the 7 children, (1 child continued to behave appropriately following initial improvement in behavior). For these 6 children, improved behavior occurred with changes in treatment components. Our results extend previous studies of direct assessment procedures conducted in outpatient clinic settings.     

Distinctiveness effects in recall:

Unusual information is generally recalled better than common information (the distinctiveness effect). Differential processing accounts propose that the effect occurs because unusual material elicits encoding processes that are different from those elicited by common material, and strong versions of these accounts predict distinctiveness effects in between-list as well as within-list designs. Experiment 1 employed a between-list design and manipulated presentation rate. Contrary to differential processing predictions, no distinctiveness effect emerged, nor did recall patterns for atypical versus common sentences differ as a function of presentation rate. Experiment 2 further tested differential processing accounts as well as representation accounts via a within-list manipulation and conditions that included experimenter-provided elaborations. Distinctiveness effects emerged in all conditions and, contrary to differential processing predictions, the pattern of recall in the elaborated conditions did not differ from that in the unelaborated conditions. Taken together, the results of this study lend more support to a representation view that suggests mechanisms related to the representation and subsequent retrievability of elements in the memory record play a major role in the distinctiveness effect.     

Pictorial enhancement of text memory: Limitations imposed by picture type and comprehension skill

We examined the kinds of information in a prose passage that is better remembered when depictive illustrations are embedded in the passage than when the passage contains no illustrations. Experiment 1 showed that (1) pictures depicting details effectively increased recall of those details and (2) pictures depicting relationships effectively increased recall of that relational information (relative to a no-picture control condition). In Experiment 2, comprehension skill was found to modulate the general effects obtained in Experiment 1. Detail pictures enhanced the recall of targeted details for all skill levels. Relational pictures enhanced recall of pictured relational information for highly skilled and moderately skilled comprehenders, but not for less skilled comprehenders. Because there were no recall differences across the different skill levels in the no-picture control condition, it is suggested that pictures may serve to enable processing in which readers would not necessarily engage under ordinary circumstances. Pictures, however, did not appear to compensate for limitations reflected in lower scores on a standardized test of reading comprehension.     

Implications of external memory for investigations of mind

External memory–records of experiences that are maintained in repositories that are external to their users–provides context for many everyday cognitive acts. Some initial research has shown that such context influences learning, remembering, and judgements of knowing. The scope of both basic and applied memory research should be broadened in ways that address issues about the interaction of external memory and mind.     

A BRIEF COMPONENT ANALYSIS OF POTENTIAL TREATMENT PACKAGES IN AN OUTPATIENT CLINIC SETTING WITH YOUNG CHILDREN

The purpose of this study was to develop outpatient clinic assessments that allowed us to assess multiple treatment variables, produce relatively quick effects, and isolate active treatment components. Assessment began by evaluating a treatment package consisting of antecedent and consequence variables followed by a component analysis to determine the separate effects of the treatment variables. Three examples of the findings are presented.     

The organization of verbs of knowing: Evidence for cultural commonality and variation in theory of mind

Cross-cultural commonality and variation in folk theories of knowing were studied by examining the organization of verbs of knowing in German and Japanese adults. German and Japanese adults performed one of two tasks: a similarity judgment task and an attribute rating task. Organizational structure was assessed for the similarity judgment task using multidimensional scaling and additive similarity tree analyses. The attribute rating task was used to describe the characteristics that organized the dimensions and clusters emerging from the scaling solutions. The folk theory of mind displayed was an information processing model with constructive components, although the constructive aspects were more salient for the Germans than for the Japanese.     

Adolescent Self-Esteem and Cognitive Skills Training: A School-Based Intervention

We developed and evaluated a school-based psychosocial prevention program for adolescents, focusing on self-esteem, negative cognitive processes, and peer isolation. Fifty-one tenth-grade students between the ages of 13–16 were recruited and randomly allocated to one of three groups; Social Cognitive Training group (SCT), Attention Placebo Comparison Group (APC) and a Waitlist Control group (WL). A pre-post design using two types of measures: specific measures of the target skills (self-esteem, self-statements) and impact measures (quality of peer relationships, acceptability of intervention for adolescents and teachers) evaluated the effectiveness and social validity of the intervention. Multivariate Analyses of Variance showed significant improvements on measures of target skills for the SCT group in contrast to the comparison conditions on reported self-esteem, and self statements, however mixed results were found on the impact measures. While the SCT group was rated as highly acceptable and useful by both adolescents and teachers, student self report ratings of quality of peer relationships showed little change across the study period. We discussed our findings in terms of the effectiveness of group based cognitive interventions in developing adolescent self-esteem and social competence, and the ecological validity of implementing programs within naturalistic settings.     

Exercise Stage of Change and Self-Efficacy in Primary Care: Implications for Intervention

Multiple chronic diseases are caused or complicated by a sedentary lifestyle. Thus, an important and challenging application of psychology in clinical settings is changing the behavior of sedentary primary care patients. This study focused on exercise stage of change and self-efficacy in a sample of adult family practice patients recruited while waiting for their scheduled physician appointment. Regarding exercise stage of change, 15% of respondents were in the Precontemplation stage, 26% in the Contemplation stage, 50% in the Preparation stage, 7% in the Action stage, and 13% in the Maintenance stage. Mean self-efficacy scores for exercise were significantly higher among respondents in the Action and Maintenance stages of change. These cross-sectional data are consistent with the hypothesis that movement through the exercise stages of change could be encouraged by clinical interventions that increase exercise self-efficacy. The identification of multiple personal opportunities for increasing exercise self-efficacy may be clinically useful in this context. Recommendations for psychologists in primary care settings in their work with physicians are offered.
