The CS-Preexposure Effect in Conditioned Taste-Aversion Learning in Golden Hamsters

In Experiment 1, golden hamsters were injected with either 0.9% saline or the nausea-inducing agent, lithium chloride (LiCL), immediately after consuming a flavored diet that was either novel or familiar. The LiCl-induced aversion was strong in hamsters for which the flavored diet was novel, but no significant aversion was observed in hamsters that were familiar with the flavored diet. In Experiment 2, the strength of the LiCl-induced aversion was related inversely to the amount of conditioned-stimulus (CS) preexposure and directly to the duration of the preexposure-conditioning interval. Thus, although some previous researchers have suggested that hamsters may not demonstrate the CS-preexposure effect in a conditioned taste-aversion paradigm, they clearly did so under the conditions of the present experiments, and moreover, the characteristics of the CS-preexposure effect in hamsters were generally similar to those observed in rats.     

Deciding the Fate of Others: The Cognitive Underpinnings of Racially Biased Juror Decision Making

In criminal law, jurors are supposed to ignore defendant race when considering factual matters of culpability. However, when judging the merits of a criminal case, jurors’ ability (or inability) to avoid bias may affect verdicts. Fact-based decision making expend cognitive resources, while heuristic-based decisions (e.g., using criminal stereotypes) conserve resources. Here, we investigated whether differences in cognitive resources and prejudice attitudes about Blacks influenced trial outcomes. We tested the impact of working memory capacity (WMC), cognitive load, prejudice, and target race (Black, White) on penalties ascribed to fictional criminal defendants in ambiguous-fact cases. Results showed that when “loaded,” prejudiced-low-WMC persons supported guilty verdicts with higher confidence more often for Black than White defendants. Conversely, regardless of WMC or prejudice attitude, participants penalized White defendants more often when not loaded. We suggest that cognitive resources and prejudice attitude influence fact-based decisions. Links to juror judgments and potential trial outcomes are discussed.     

The Relationship Between Adult Happiness and Self-Appraised Childhood Happiness and Events

The primary purpose of the present research was to relate questionnaire-assessed self-reported childhood happiness and events to adulthood happiness in 387 nonclinical participants. Although childhood happiness and adult happiness were found to be significantly correlated (r = .28, p < .001), there was little relationship between reported adult happiness and reported specific childhood events and circumstances. Childhood events and circumstances, however, were much more highly correlated with childhood happiness (R = .64). Thirty-four percent of the persons who said they were unhappy or very unhappy as a child, but only 9% who said they were happy or very happy as a child, reported that they were unhappy or very unhappy as adults.     

A Review of: “Groups: Applying the Functional Group Model,edited by Sharan L. Schwartzberg,Margot C. Howe, & Mary Alicia Barnes, 2008”

This paper describes the process of developing and implementing a new information system, POTENT, as part of a quality assurance exercise to improve occupational therapy documentation in the hospital record. Results of a Retrospective criteria audit are presented and are supportive of a more rigorous examination of POTENT's impact on documentation practices.     

Relationship enhancement with premarital dyads: A six-month follow-up

Abstract

The purpose of the present study was to assess the short-term and longterm effectiveness of relationship enhancement on the self-disclosure and empathy skills of premarital dating couples. Nineteen couples were given the Guerney Relationship Enhancement Program over an eight week period, while 18 other couples were given a lecture/discussion program on relationship development. Behavioral assessments of self-disclosure and empathy skill levels were taken prior to training, immediately following training, and six months after training. Results indicated that from both pretest to posttest and pretest to follow-up, the relationship enhancement couples, relative to the lecture/discussion couples, demonstrated a significant increase in both self-disclosure and empathy skill levels. Discussion centers on the implications of the durability of the skills learned as well as on suggestions for future research on skill generalization to social interactions with others.     

Pre-Entry Expectations,Attitudes, and Intentions to Join Predict Military Tenure

The objective of this study was to examine pre-entry expectations, attitudes, and intentions as predictors of tenure among military members. Data from nationally representative (U.S.) samples of youth on attitudes toward military service, expectations about the effect of joining the military on quality of life, and intentions to join the military were linked to tenure among those who later joined the military as adults. Results from survival analyses indicate that those who initially had no desire to join the military and did not expect military service to have positive effects on their quality of life, but ultimately joined the military nonetheless, tended to have shorter military careers. Explanations for these findings are offered along with implications for military staffing.     

The Psychology of Gender Differences in Religion: A Review of Empirical Research

This paper presents, discusses and evaluates empirical studies concerned with gender differences in religion. Within the psychology of religion two main groups of theories have been advanced to account for gender differences in religiosity. The first group of theories concentrates on social or contextual influences which shape different responses to religion among men and women. This group may be divided into two categories: gender role socialisation theories and structural location theories. The second group of theories concentrates on personal or individual psychological characteristics which differentiate between men and women. This group may be divided into three categories: depth psychology theories, personality theories and gender orientation theories. It is concluded that gender orientation theories provide the most fruitful source for further research.     

Memory as discrimination: What distraction reveals

Recalling information involves the process of discriminating between relevant and irrelevant information stored in memory. Not infrequently, the relevant information needs to be selected from among a series of related possibilities. This is likely to be particularly problematic when the irrelevant possibilities not only are temporally or contextually appropriate, but also overlap semantically with the target or targets. Here, we investigate the extent to which purely perceptual features that discriminate between irrelevant and target material can be used to overcome the negative impact of contextual and semantic relatedness. Adopting a distraction paradigm, it is demonstrated that when distractors are interleaved with targets presented either visually (Experiment 1) or auditorily (Experiment 2), a within-modality semantic distraction effect occurs; semantically related distractors impact upon recall more than do unrelated distractors. In the semantically related condition, the number of intrusions in recall is reduced, while the number of correctly recalled targets is simultaneously increased by the presence of perceptual cues to relevance (color features in Experiment 1 or speaker’s gender in Experiment 2). However, as is demonstrated in Experiment 3, even presenting semantically related distractors in a language and a sensory modality (spoken Welsh) distinct from that of the targets (visual English) is insufficient to eliminate false recalls completely or to restore correct recall to levels seen with unrelated distractors . Together, the study shows how semantic and nonsemantic discriminability shape patterns of both erroneous and correct recall.
