Irrelevant differences in the "same"--"different" task

This article examines the effects of irrelevant information on the multidimensional "same"--"different" task. Subjects were instructed to compare two geometric figures with respect to certain attributes but to ignore other attributes in making the "same"--"different" decision. The irrelevant attributes were chosen in such a way that they could not easily be ignored to see how the existence of irrelevant differences would affect the comparison process. As expected, the overall latencies were longer than is usually found in tasks with no irrelevant differences. However, the nature of the comparison process appeared unchanged. The usual finding of a "fast-same" phenomenon persisted even when irrelevant information was present. The similarity of the results in this task to results in the "same"--"different" task with no irrelevant features supports the idea that the same comparison mechanism is used whether or not irrelevant differences are present in the stimulus pairs. The results suggest a more general-purpose comparison mechanism than is usually included in models of this task. Two-process models of visual comparisons are thus ruled out entirely. A modified version of Krueger's noisy-operator theory does appear consistent with the results.

"Lost in a shopping mall" -- a breach of professional ethics

The "lost in a shopping mall" study has been cited to support claims that psychotherapists can implant memories of false autobiographical information of childhood trauma in their patients. The mall study originated in 1991 as 5 pilot experiments involving 3 children and 2 adult participants. The University of Washington Human Subjects Committee granted approval for the mall study on August 10, 1992. The preliminary results with the 5 pilot subjects were announced 4 days laters. An analysis of the mall study shows that beyond the external misrepresentions, internal scientific methodological errors cast doubt on the validity of the claims that have been attributed to the mall study within scholarly and legal arenas. The minimal involvement -- or, in some cases, negative impact -- of collegial consultation, acadmic supervision, and peer review throughout the evolution of the mall study are reviewed.     

Vocational behavior and career development, 1978: A review

In sum, the research in 1978 was diverse and of good quality and quantity. However, there continues to be a clear need for longitudinal research of all kinds (in particular on the career development process) and a need for additional research with the employed adult population, although the past few years demonstrate improvement in the latter area.In 1978 the most productive research area as suggested by this review was associated with the women's movement and manifested by research primarily on sex stereotyping and women's careers. Ranking second was the topic of theoretical developments in vocational behavior led by the research on Holland's constructs. These two research trends accounted for about 50 studies; 26 and 24, respectively. Job satisfaction assumed the third position with some concentration on satisfaction and work motivation. Next and very much clustered were life-span aspects, assessment, and job performance. Each of these research themes stimulated about 17 studies that were reviewed here. Vocational interventions and race differences received moderate attention while job interview variables and occupational environments sparked very limited work in the more psychologically oriented journals.The major contributor to the 1978 review was of course the Journal of Vocational Behavior (62 studies), followed by the Journal of Applied Psychology (25 studies). Five other journals contributed an average of about 10 studies. These were the Journal of Counseling Psychology, Journal of Measurement and Evaluation in Guidance, the Journal of Organizational Behavior and Human Performance, Personnel Psychology, and the Vocational Guidance Quarterly. These appear to be the major journals publishing work on vocational behavior and career development.Finally, the volume of research on vocational psychology continued on an upward trend in 1978. This review and the previous reviews (Betz, 1977; Osipow, 1976; Zytowski, 1978) clearly document this trend.     

ORGANIZATIONAL COMMUNICATION: 1978

With roots in social psychology, human relations, and organizational theory and behavior, the discipline of organizational communication has emerged in the last 25 years with its own content, methodology, and applications. Although one of the first major literature reviews of this field was produced about 15 years after much of the early foundation research had been completed (Guetzkow, 1965), the next major reviews were published in half the time (Porter & Roberts, 1972; Redding, 1972). As further evidence of the sheer quantity of research being completed in this new discipline, four additional reviews and syntheses were published during the next four years (Pietri et al., 1974; Goldhaber, 1975; Bernstein, 1976; Richetto, 1977). In fact, as Richetto closed his 1976 overview of the field, he predicted that there would “likely be continued attempts at integrating and synthesizing findings” (p. 336). Little did he realize that within two years, three additional reviews would appear (Dennis, Goldhaber, Yates, 1978; Farace, Taylor, Stewart, 1978; Monge, Edwards, Kirste, 1978). The present synthesis and review, with its emphasis on findings and implications, combines the results of recent North American and European research with those of the first 16 studies completed by the International Communication Association (1CA) Communication Audit. We have divided the review into three major sections: a historical overview of the major findings from both North America and Europe; major findings from the ICA Communication Audit; and implications of all major findings for future research.     

Assessing the Truthfulness of Witness Statements Made by Children (Aged 7--8, 10--11, and 13--14) Employing Scales Derived from Johnson and Raye's Model of Reality Monitoring

The goal of this study was to determine whether children's true and false witness statements could be differentiated using the model of reality monitoring. The effects of age and verbal ability on scales based on the model were also investigated. Children (N = 68) from three different age-groups (7--8, 10--11, and 13--14 years) made both a true and a false statement concerning a mildly traumatic event. The statements were analysed using the Revised Memory Characteristics Questionnaire. The vocabulary sub-scale of the WISC-R was also administered. True statements were found to contain more sensory information and expressions of time, and less affective information. Overall, 64% of the statements were correctly classified on the basis of the scales. Older children received higher scores on most of the reality monitoring scales compared to the youngest children regardless of the truthfulness of their statements. Furthermore, the verbal ability of the children was positively associated with scores on several of the scales. The classification accuracy suggests that the model should not be applied to individual cases of child testimony. Although the final decision concerning the usefulness of the scales should be based on ecologically valid field studies.     

Threat and authoritarianism in the United States, 1978-1987

Studies at both the individual and collective levels have implicated threat as an important factor in authoritarianism. As a follow-up to Sales's (1973) study relating behavioral indicators of authoritarianism to levels of social threat, the present research analyzed archival data from the United States for high-threat (1978-1982) and low-threat (1983-1987) periods. Societal measures of most attitude and behavioral components of the authoritarian syndrome significantly decreased between the high-threat and the low-threat periods. These results support the threat-authoritarianism relationship but also suggest a more complicated theoretical model that links perceived social conditions, arousal of authoritarian sentiments, dispositional authoritarianism, and the nature of political appeals--particularly those that engage authoritarian aggression.
