Training requirements and retention characteristics of serial list organization by macaque monkeys

This work evaluated the prospect that organizational accounts of the retention of list information by monkeys might be an artifact of familiarity with conditional relationships. Seven sophisticated macaques were trained on four five-item lists. Each acquisition selectively excluded one of the internal conditional pairs of the typical four-problem sequence (AB,BC,CD,DE) that defines a five-item serially ordered list. Then, all possible novel pairings and the trained pairs appeared together in a test. After this, the previously omitted pair was trained and animals were retested. On all tasks, initial tests revealed little organization and much intersubject variability of characteristic choice strategies, but subsequent inclusion of all four conditional pairs always yielded organized serial choice. On both the four-problem tests and in a later retention, errors were directly related to interitem distance between the objects paired on test trials. These results helped to specify the conditions required for demonstration of non-human primate analogs of transitivity, and showed that even sophisticated monkeys organize information in retention only if they know all interitem relationships.

Does Alternating Between Masculine and Feminine Pronouns Eliminate Perceived Gender Bias in Text?

This study explores whether alternating betweenthe pronouns he and she ina text is an effective way to avoid sexist language.Participants were psychology students at a largemidwestern university and were predominately White and frommiddle-class backgrounds. Students read two versions ofan essay, one that alternated between masculine andfeminine pronouns and one that exclusively used paired, he or she-type pronouns. Readersperceived the alternating version to be biased in favorof females and lower in overall quality than the pairedversion. However, the alternating version appeared to be more effective at combating sexism,suggesting an alternating strategy may be desirable forauthors with this goal. If the author is not primarilyconcerned with increasing readers' awareness of gender issues, techniques such as pluralization or thesingular they may be moreappropriate.     

The Presence of Odd Pricing in the Texas State Lottery1

We examined 443 drawings from the Texas state lottery from 1992 to 1997 to determine whether odd pricing effects would be found in multimillion-dollar lotteries. Specifically, we predicted that many more lottery tickets than expected would be purchased when the jackpot amount was $10 million than when it was $9 million. Three findings emerged. First, the higher the jackpot, the more tickets were purchased. Second, odd pricing effects were found at $10 million such that approximately 670,000 more tickets were purchased than expected. Third, controlling for the jackpot amount, there were approximately 620,000 fewer tickets purchased for each drawing per year. This final finding provides evidence that people are becoming less interested in multimillion-dollar lotteries.     

An Evaluation of the Job Stress Questionnaire with a Sample of Entrepreneurs

A modified version of Caplan's Job Stress Questionnaire (JSQ) was administered to 169 male and 56 female entrepreneurs. Entrepreneurs were found to have higher levels of stress associated with workload than with role ambiguity and underutilization of skills. Compared to scores reported previously for various occupational categories, the entrepreneurs scored significantly higher than did white collar, blue collar, and professional groups on the workload scale and significantly lower on scales measuring role ambiguity and under-utilization of skills. These results may be due to the nature of entrepreneurial activity, which is often characterized by heavy workloads, long hours, and a self-established role in the organization. Additionally, the factorial composition of the JSQ and its internal consistency were examined. Evidence of convergent and discriminant validity at the item and subscale level confirmed the a priori dimensions of the JSQ, although the internal consistency of the scales were low to moderate. The need for various improvements in the measurement of occupational stress is briefly discussed.
