Mediators of age-related differences in recollective experience in recognition memory

This study examined states of awareness with the Remember/Know paradigm during verbal recognition memory in young and old adults. Following the presentation of a word list, subjects undertook a recognition test and indicated whether they could consciously recollect its prior occurrence (R) or recognize it on some other basis, without conscious recollection (K). In this individual-difference approach we also incorporated various processing-speed and working-memory measures to study the link between aging, states of awareness and processing resources. The results revealed that, compared to younger adults, older adults exhibited a decline in the amount of R responses during the recognition test whereas the amount of K responses did not change. Structural equation modeling indicated that a slower processing speed associated with a limited working-memory capacity is a key to explaining age-related variance in conscious recollection. The findings offer further support for the distinction between remembering and knowing and for the processing-resources hypothesis of aging.     

Perceptions of and Attitudes toward Plagiarism and Factors Contributing to Plagiarism: a Review of Studies

The abundance of information technology and electronic resources for academic materials has contributed to the attention given to research on plagiarism from various perspectives. Among the issues that have attracted researchers’ attention are perceptions of plagiarism and attitudes toward plagiarism. This article presents a critical review of studies that have been conducted to examine staff’s and students’ perceptions of and attitudes toward plagiarism. It also presents a review of studies that have focused on factors contributing to plagiarism. Our review of studies reveals that most of the studies on perceptions of plagiarism and attitudes toward plagiarism lack an in-depth analysis of the relationship between the perceptions of plagiarism and other contextual, sociocultural and institutional variables, or the relationship between attitudes toward plagiarism and students’ perceptions of various forms of plagiarism. Although our review shows that various factors can contribute to plagiarism, there is no taxonomy that can account for all these factors. Some suggestions for future research are provided in this review article.     

Dyadic Cross-Sectional Associations Between Negative Mood,Marital Idealization,and Relationship Quality

This study aimed to evaluate (a) dyadic associations between relationship quality (RQ) and both depressive and anxious mood (DM and AM), (b) reciprocity hypotheses of negative mood within dyadic interactions, and (c) mediational role of marital idealization between negative mood and relationship quality. Actor-partner interdependence models (APIMs) were performed using data from a sample of 198 dyads. Our results showed that (a) these two facets of negative mood did not have the same weight on RQ and that they had a gender-specific effects pattern, and (b) there was no support for the mood transmission hypothesis. Men's DM displayed direct and indirect (via marital idealization) actor as well as partner effects on RQ, whereas women's DM displayed only a direct actor effect on RQ. There were no significant direct actor effects of AM on RQ, meaning that this link is fully mediated by marital idealization. However, only women's AM showed such indirect effects on RQ.
