Age-Related Differences in Memory Illusions: Revelation Effect

Older adults are often more susceptible to various illusions and distortions of memory than young adults. In the experiments reported here, we explored the question of whether normal aging was associated with a larger revelation effect, an illusion of memory in which items that are revealed gradually during a recognition test are more likely to be called old than unrevealed items that are shown in their entirety. Contrary to expectations, older adults were not susceptible to this memory illusion. A revelation effect occurred for young but not older adults, even when older adults were similar to young adults on measures of recognition and repetition priming. When data across experiments were combined, there was evidence for a negative revelation effect in older adults in which revealed items were less likely called old than unrevealed items. These results place boundary conditions on the claim that older adults are more susceptible than young adults to memory illusions, and imply that one or more mechanisms underlying the revelation effect are age sensitive.     

The Role of Long-Term Memory in Digit–Symbol Test Performance in Young and Older Adults

ABSTRACT

The psychological functions assessed by substitution tests, and the age-related performance decline, are not well understood. Here several aspects of long-term memory were manipulated across younger and older adults. A 45-page Digit–Symbol test was employed. Each page contained a 9-item digit symbol code-table and 9 response items. There were 9 study conditions with each condition deployed across 5 pages, or trials, of the test. The conditions were formed by crossing two within-subjects factors, each with 3 levels. The first factor, Digit Order, pertained to having the code table digits in numerical order vs. a pseudo-random order fixed across trials vs. a pseudo-random order that varied across trials. The second factor, Symbol Pairing, pertained to having a fixed digit–symbol pairing across trials vs. having a varying digit–symbol pairing across trials vs. having a novel set of 9 symbols introduced on each of the 5 trials. Including the additional factor, Age, resulted in a 2 × 3 × 3 mixed randomised block design. The older group was slowed, F(1, 22) = 17.267, p < .001, and overall-performance was poorer when the digits were arranged non-numerically, F(1,44) = 55.403, p < .001. An Age by Symbol–Order interaction indicated that use of novel symbols disadvantaged only the older participants, F(1, 44) = 6.577, p = .014. While there was no evidence that incidental paired-associate learning or spatial memory affect digit–symbol performance, symbol familiarity may be important to digit symbol test completion in older adults. The benefit of ordinally arranged digits in the coding table highlights a fundamental process difference between Digit–Symbol and Symbol–Digit test formats.     

Taking As: Experience & Judgment in the Life of Agents

Although appearances may deceive them, agents are capable of achieving their ends; this success is frequently explained by the fact that the agents may, for example, see a stick in water as bent without believing that it is actually bent. Although the notion of ‘seeing as’ is supposed to both bridge the gap between experience and action and explain our reaction to illusions, such accounts break down because of their exclusive focus on visual episodes and their tendency to interpret the metaphysics of agency in a psychologistic fashion. This paper shows that ‘seeing as’ needs to be understood as a species of the genus ‘taking as.’ The genus admits a wider array of expression, in terms of the kinds of attitudes, actions, and epistemological statuses involved. Such an analysis allows us to avoid the problems of ‘seeing as’ accounts and deepens our understanding of the relationship between practical and theoretical reason.

Research Productivity and Performance of Journals in the Creativity Sciences: A Bibliometric Analysis

A bibliometric approach was employed to analyze the research productivity and performance of creativity studies between 1965 and 2012. A dataset was constructed using all publications and citations retrieved from four key journals that publish creativity research: Journal of Creative Behavior (JCB), Gifted Child Quarterly (GCQ), Creativity Research Journal (CRJ), and Psychology of Aesthetics, Creativity, and the Arts (PACA). Major findings in this study include: (a) During the study period, the four journals have published 1,891 articles on creativity and they have been cited 11,709 times; (b) the impact factors of the four journals increased from lower than .50 in 2002 to over 1.0 in 2012; in 2012 PACA had the highest impact factor, followed by CRJ; (c) JCB published the most creativity papers and CRJ had the most citations; (d) about a third of the articles published in the four journals have never been cited. Implications for the field of creativity are discussed.     

A Comparative Analysis of Sport and Business Organizations: Factors Perceived Critical for Organizational Success

The purpose of the present investigation was to compare and contrast sport and business leaders' perceptions regarding what makes for a successful organization. Twenty sport ( N = 10) and business ( N = 10) leaders were interviewed and asked about their perceptions of organizational effectiveness in the area of group dynamics including (a) leadership, (b) group cohesion, and (c) communication. Using qualitative methods, results revealed more similarities than differences, with most sport and business leaders in agreement on the factors relating to organizational success. Specifically, all higher- and lower-order themes were identified by leaders in both areas, the emphasis simply being a matter of degree. Some of the more notable differences included business leaders putting more emphasis on being honest and being a reflective listener, whereas sport leaders emphasize interactions with others and having positive reinforcement in their communications. These similarities and differences are discussed in terms of the extant literature, and future directions for research are offered, such as investigating how to specifically enhance the transfer of skills and principles between sport and business settings.     

Effects of Augmenting Response Options on MMPI–2 RC Scale Psychometrics

A number of empirical investigations indicate that tests with a greater number of response options tend to yield better psychometric performance. We hypothesized that a version of the MMPI–2 with a polytomous response format would outperform the standard dichotomous format in terms of observed score reliability and validity. Two versions of the MMPI–2 RC scales were administered consecutively in counterbalanced order to 199 undergraduate students attending a large Midwestern university: the standard true–false version, and an experimental version containing 4 response options (very true, mainly true, slightly true, and false, not at all true). After participants completed both versions, 2 scales from the Multidimensional Personality Questionnaire (MPQ) were administered to assess differences in convergent validity. Results showed enhancements in reliability for all RC scale scores and increases in the convergent validity of scores. Directions for further investigation and potential implications for future test development are discussed.     

The Longitudinal Psychometric Properties of the EAS Temperament Survey in Adolescence

Studies on the psychometric properties of the EAS Temperament Survey (EAS) have produced equivocal results. In particular the psychometrics of the EAS are largely unknown in adolescence. Confirmatory factor analysis was used to explore the EAS structure in adolescents. Structural equation modeling was also used to assess measurement invariance and factor stability. A modified 4-factor model provided the best fit to the data and demonstrated reasonable longitudinal invariance and stability. Furthermore, the standardized factor scores correlated at near unity with the sum of observed scores, suggesting factor interpretations remained unchanged. However, the modifications suggest that further work is necessary.
