Patterning,partial reinforcement,and N-length effects at spaced trials as a function of reinstatement of retrieval cues

Four experiments are reported which demonstrate the importance of the reinstatement of retrieval cues in partial-reinforcement experiments using spaced trials. Reinstatement occurs when the goalbox and startbox are of the same brightness (gray). Nonreinstatement occurs when the goalbox and startbox are of different brightnesses (black-and-white striped vs gray). Under reinstatement conditions, both a partial-reinforcement effect (PRE) and N-length effects were observed whether small reward or large reward was used. Under nonreinstatement conditions, a PRE was observed when large reward was used but not when small reward was used; N-length effects were not observed either with large or small reward. Finally, using a 24-hr intertrial interval, single alternation patterning was found only with a group receiving large reward, a long nonreward confinement duration, and reinstatement. These results are not consistent with the notion that massed and spaced trials are governed by separate mechanisms, and support an explanation of both massed and spaced trials based on E. J. Capaldi's sequential theory.     

Exposure to print and word recognition processes

The effect of exposure to print on the efficiency of phonological and orthographic word recognition processes was examined by comparing two groups of university students having similar reading comprehension scores but different levels of exposure to print. Participants with a high level of exposure to print were faster and more accurate in naming pseudowords, in choosing the correct member of a homophone pair, and in making lexical decisions when nonwords were pseudohomophones. In the lexical decision task, low-print-exposure participants were more sensitive to the frequency of the orthographic patterns in the stimuli. The results of a form priming task demonstrated that high-print-exposure participants more quickly and strongly activated the orthographic representations of common words and subsequently more strongly activated the corresponding phonological representations. Even among successful students, differences in exposure to print produce large differences in the efficiency of both orthographic and phonological word recognition processes.     

Study Preregistration: An Evaluation of a Method for Transparent Reporting

Study preregistration promotes transparency in scientific research by making a clear distinction between a priori and post hoc procedures or analyses. Management and applied psychology have not embraced preregistration in the way other closely related social science fields have. There may be concerns that preregistration does not add value and prevents exploratory data analyses. Using a mixed-method approach, in Study 1, we compared published preregistered samples against published non-preregistered samples. We found that preregistration effectively facilitated more transparent reporting based on criteria (i.e., confirmed hypotheses and a priori analysis plans). Moreover, consistent with concerns that the published literature contains elevated type I error rates, preregistered samples had fewer statistically significant results (48%) than non-preregistered samples (66%). To learn about the perceived advantages, disadvantages, and misconceptions of study preregistration, in Study 2, we surveyed authors of preregistered studies and authors who had never preregistered a study. Participants in both samples had positive inclinations towards preregistration yet expressed concerns about the process. We conclude with a review of best practices for management and applied psychology stakeholders.

Potentially Traumatic Experiences,Academic Performance,and Psychological Distress: The Role of Shame

The purpose of this study was to investigate the role of shame associated with previous potentially traumatic experiences, satisfaction with academic performance, and psychological distress among college students (N = 245) in Mainland China. Results indicated that previous experiences of potentially traumatic events were directly related to depressive symptoms and indirectly related through characterological shame and hopelessness. In addition, characterological shame and bodily shame were 2 distinct forms of shame that had unique associations with psychological distress.     

Inference,explanation, and asymmetry

Explanation is asymmetric: if A explains B, then B does not explain A. Traditionally, the asymmetry of explanation was thought to favor causal accounts of explanation over their rivals, such as those that take explanations to be inferences. In this paper, we develop a new inferential approach to explanation that outperforms causal approaches in accounting for the asymmetry of explanation.

The clergy: a valuable resource for church members with alcohol problems

The role of the minister or pastor is pivotal in the development and operation of church-based services and programs and in the delivery of services. They can initiate changes and can equip the officers and members so that families troubled by substance abuse issues can find a climate of acceptance, understanding, and recovery in the local congregation. They can also serve as a referral source to members of the mental health professionals for assistance with alcohol and other substance abuse problems. For our purposes in this article, the term "clergy" refers to congregational and parish clergy. The focus of this discussion pertains to the role of clergy in providing assistance for members of their congregations with substance abuse problems. Implications and recommendations for collaborations and specific resources are also included that may increase the awareness of those issues and to increase effectiveness of service to those needing it.     

Dynamic valuation: Preference changes in the context of face-to-face negotiation

This experiment examines the dynamics of preference change in the context of face-to-face negotiation. Participants playing the role of “student” or “financial aid officer” exchanged proposals regarding the terms of a student loan. Consistent with dissonance theory, participants increased their liking for proposals they offered and/or ultimately accepted. The reactance theory prediction that participants would devalue proposals received from their opponents was confirmed for loan officers, but not for students. A pair of experimental manipulations involving the pre-rating of proposals and/or the opportunity for participants to engage in a brief discussion period prior to the initial exchange of offers mediated these effects, and influenced subsequent rates of agreement. Underlying attributional mechanisms and the implications of these findings for facilitating agreements are discussed.
