Improving retrieval

The present research investigated whether ability for retrieval might be improved by practice at retrieval. Retrieval practice trials, each of 10 min duration, required subjects to attempt to recall as many examples as possible of a designated category. Two kinds of practice were investigated. Subjects given general practice attempted to recall a different category on each successive practice trial. Subjects given specific practice attempted to recall the same category on each successive practice trial. General practice had a negligible effect on recall, even when subjects practised daily for over a month. In contrast, specific practice substantially improved recall, facilitating retrieval of 50 to 100 per cent of all the example subjects known for a category.     

Oligopoly Bargaining: Effects of Agreement Pressure and Opponent Strategies

Previous research on oligopoly bargaining has shown soft strategies to be superior to tough strategies and has suggested that this effect may be moderated by agreement pressure. However, previous research is difficult to interpret because the effects of strategy changes and subsequent strategies have not been adequately tested. Female students from introductory psychology classes were assigned the role of buyers and bargained with initially soft or tough and subsequently soft or tough programmed (seller) strategies under low or high agreement pressure. Subjects had the opportunity to bargain with the strategy (seller) of their choice and to change sellers at any time. As hypothesized, soft seller strategies were found to be superior to tough strategies. In addition, the superiority of soft seller strategies was increased by low agreement pressure.     

Natural experiments and the educational context: The environment and effects of an alternative inner-city public school on adolescents

The 1-year impact of attending a public alternative high school on two cohorts of adolescents who gained entrance to the school through a lottery was studied. Adolescents who had applied to the school but were not selected in the lottery served as a control group. The nature of the alternative high school environment is described, and the outcome of this natural experiment defined in terms of reactions to school, attitude change, and student achievement. In general, the alternative school positively affected student satisfaction with a variety of aspects of school life and induced some positive change in interracial attitudes while not harming student achievement. Race effects were found in the areas of achievement and interracial attitudes. Implications for the study of natural experiments in general and the specific data in particular are drawn.     

Being attractive,advantage or disadvantage? Performance-based evaluations and recommended personnel actions as a function of appearance,sex, and job type

Prompted by a concern with the effects of appearance on how individuals and their work are regarded and how rewards are allocated in work settings, an experiment was conducted to determine whether physical attractiveness differentially affects the performance evaluations and recommended personnel actions for men and women holding managerial and nonmanagerial jobs. As predicted, attractiveness proved to be advantageous for women in nonmanagerial positions and disadvantageous for women in managerial ones. Unexpectedly, however, appearance had no effects whatsoever on reactions to men. Additional results indicated that attractiveness enhanced the perceived femininity of our female stimulus people, but did not enhance the perceived masculinity of those who were male. These data were interpreted as supportive of the idea that the differential effects of appearance in work settings are mediated by gender characterizations, and that fluctuations in the perceived person-job fit are key to understanding the seemingly inconsistent reactions to attractive and unattractive women in employment situations. The theoretical and applied implications of these findings are discussed.     

Cognitive Processing of Traumas: The Role of Intrusive Thoughts and Reappraisals1

Cognitive processing theories of post-traumatic adaptation (Horowitz, 1986a; Janoff-Bulman, 1992) propose that repeated comparisons of trauma content with preexisting cognitive schemas result in trauma reappraisal or schematic revision. Thus, intrusive ruminations should facilitate cognitive integration and resolution of past traumas. However, research has shown that some survivors become stuck in endless, repetitive rumination cycles. This raises the issue of how to differentiate ruminations that promote cognitive integration from those that merely prolong or exacerbate psychological distress. Identifying substantive dimensions for categorizing cognitions about past traumas could enhance prediction of their effects on adjustment and inform clinical treatment interventions. This paper seeks to: (a) Assess the current state of theoretical knowledge concerning cognitive adaptation to trauma, (b) integrate theoretical postulates with empirical research findings, (c) define gaps or inconsistencies in our understanding of the cognitive adaptation process, and (d) identify foci for future theory and research.     

The effects of unvocalized music on short-term memory

The studies reported here investigated the role of background music in verbal processing. The experiment was a partial replication of Salame and Baddeley (1989), where the effect of music on the recall of digits, was examined, but included an additional key condition where participants heard instrumental music without the words usually associated with it. In this case we used nursery rhymes. In addition, articulatory suppression was manipulated as a tool to look at the role of working memory in the task. The relationship between long-term memory and working memory was further explored by using an implicit memory task to examine verbal memory effects for words associated with the music but not actually heard. The results indicated that background, instrumental music, long-associated with words, significantly impairs concurrent verbal processing. These long-term memory effects on working memory were, however, not associated with implicit memory effects, and no priming was observed.     

A Spanish-language prenatal family health evaluation questionnaire: Construction and pilot implementation

The Family Planning Council of America has constructed and implemented a genetic history questionnaire, the Family Health Evaluation, to elicit risk factors, to increase clients' knowledge about reproductive choices, and to improve access to genetic services. The objective of the present study was to develop and implement a Spanish-language version of the Family Health Evaluation for data collection and risk assessment. The content of the Family Health Evaluation was modified to more clearly reflect the risks, exposures, and medical needs of an Hispanic, largely Mexican-American, population. In the present study, the questionnaire was administered to women presenting for prenatal care. The data collected in this pilot study indicate that the questionnaire is effective in identifying individuals and families who would benefit from receiving additional information about a medical condition in their families, from genetic counseling or from a referral for high-resolution ultrasound or other diagnostic procedures.     

The Role of Relational Processing in Memory for Actions: A Negative Enactment Effect in Free Recall

The enactment effect occurs if people remember items that they enacted or enacted symbolically during study better than items that they were simply asked to remember. Enactment is generally believed to lead to thorough processing of individual items. There has been some controversy as to whether the superior processing of information concerning the relations between action phrases (i.e. whole-list relational information) may additionally contribute to the enactment effect. The extant empirical data on this issue seem contradictory. In the account brough forward here, it is hypothesized that whole-list relational information is processed better during enactment than during verbal learning only if it taps the same aspect of a concept as the verb-object relational information within each action phrase. It is processed worse if these two types of information tap different aspects of a concept. This explanation represents an extension of the three-factor account of positive and negative generation effects to the field of memory for actions. To provide evidence for this account, positive and, notably, negative enactment effects in object recall and in organization scores are demonstrated in three experiments with a total of 246 participants.     

Challenging Discourse Themes Reproducing Gender in Heterosexual Dating: An Analog Study

Societal discourses tied to gender play apowerful role in shaping ideas and views about normalsexual experience. This study investigated whether“male sexual drive” discourse themes inheterosexual dating could be reproduced in a laboratorysetting, and whether these themes could be disrupted bymeans of a laboratory intervention. Young, single,heterosexual adults, most of whom were Caucasian and middle class, role played a series of datingscenarios. In half of the 37 dyads, male participantswere instructed to initiate a first date and then latergreater sexual intimacy, to which their female partners were instructed to say they were notready (the condition designed to reproduce dominantdiscourse themes). In the other half, the instructionsfor the male and female partners were reversed (the condition designed to change or disruptdominant discourse themes). Analysis of the role-playeddialogues indicated that dominant discourse themesassociated with the male sexual drive discourse wereprevalent in both experimental conditions. Ways ofbroadening our understanding of how gender processes arereproduced and disrupted are discussed in the context ofheterosexual dating relationships.
