Bias effects in word fragment completion in young and older adults

Young and older adults were tested on a word fragment completion task in which correct solutions were studied words, words orthographically similar to studied words, or new words. In Experiments 1 and 2, the standard production version of the word fragment completion task was used; older adults had reduced benefits of prior exposure to target words and slightly decreased costs. However, costs and benefits did not differ across age in a forced-choice version of the task (Experiment 3). At a behavioral level, the results are contrary to predictions that age differences in word fragment completion priming effects will be greater when there is a strong competitor for the correct solution and that age differences in both costs and benefits will be smaller for identification than for production tasks. Theoretical implications of these findings are considered.     

Interpretability, validity, and the minimum important difference

Patient-reported outcomes are increasingly used as dependent variables in studies regarding the effectiveness of clinical interventions. But patient-reported outcome measures (PROMs) do not provide intuitively meaningful data. For instance, it is not clear what a five point increase or decrease on a particular scale signifies. Establishing ‘interpretability’ involves making changes in outcomes meaningful. Attempts to interpret PROMs have led to the development of methods for identifying a minimum important difference (MID). In this paper, however, I draw on Charles Taylor’s distinction between weak and strong evaluations to suggest that identifying a MID, specifically, a MID that uses a patient-reported reference group, may not provide an adequate interpretation of these measures. Moreover, I argue that the difficulty with interpreting these measures is tied to a larger problem concerning their validity. If researchers wish to interpret PROMs, they may first need to know more about the constructs they attempt to measure, namely, quality of life.     

Lack of autonomy and self-control: Performance contingent rewards lead to greater depletion

Exerting self-control appears to deplete a needed resource, which leads to poorer self-control subsequently. However, the amount of depletion may vary, based on how controlling versus autonomy supportive the situation is. In particular, feeling compelled to exert self-control may deplete more strength than having more freedom when exerting self-control. In three experiments, participants who were given performance contingent rewards to exert self-control performed more poorly on a subsequent test of self-control than participants who were non-contingent rewards. There were no differences in mood, arousal, or anxiety between the groups; however, feelings of autonomy were related to self-control performance. The results have implications for understanding self-control depletion, as well as the impact of autonomous motivation on self-control performance.

The Role of Hostile and Benevolent Sexism in Women's and Men's Perceptions of the Menstruating Woman

Perceptions of menstruating women were studied in a sample of 244, predominantly European American, college freshmen. Both women and men rated the menstruating woman, as compared with the average woman, as higher on the Neuroticism factor from Lippa's (1991) measure of the Big Five personality factors. Men also rated her as lower on the Openness, Agreeableness, and Conscientiousness factors, and women rated her lower on the Extraversion factor. Women rated her as perceiving herself as less masculine and more feminine. Both women and men rated her as less energized and sexy, but more irritable,sad, and angry. In addition, men rated her as less clean and fresh,nurturing, and reasonable, and more spacey and annoying. Significant relationships were found between negative impressions of the menstruating woman and the Hostile Sexism Scale ( Glick & Fiske, 1996 ). Although most ratings by men and women were negative, women perceived the menstruating woman as more maternal,strong, and trustworthy.     

The individual and “the general situation”: The tension barometer and the race problem at the University of Chicago, 1947–1954

This article explains how social theories that posited white attitudes as the root of racial injustice gained traction in postwar social thought. Examining the production of a “tension barometer,” an attitude survey that scholars from the University of Chicago's Committee on Education, Training, and Research in Race Relations created to predict interracial violence, I chart vigorous debate over the nature and causes of racial oppression in the critical postwar decades. Available—and unavailable—social scientific frameworks, activists” interests, and emerging anticommunism, the Committee's history shows, created an environment where individualistic conceptions of the race problem won out, despite critique. © 2010 Wiley Periodicals, Inc.     

Effects of repetition and response deadline on associative recognition in young and older adults

The present study examined the joint effects of repetition and response deadline on associative recognition in older adults. Young and older adults studied lists of unrelated word pairs, half presented once (weak pairs) and half presented four times (strong pairs). Test lists contained old (intact) pairs, pairs consisting of old words that had been studied with other partners (rearranged lures), and unstudied pairs (new lures), and participants were asked to respond "old" only to intact pairs. In Experiment 1, participants were tested with both short and long deadlines. In Experiment 2, the tests were unpaced. In both experiments, repetition increased hit rates for young and older adults. Young adults tested with a long deadline showed reduced (Experiment 1) or invariant (Experiment 2) false alarms to rearranged lures when word pairs were studied more often. Young adults tested with a short deadline and older adults tested under all conditions had increased false alarm rates forstrong rearranged pairs. Implications of these results for theories of associative recognition and cognitive aging are explored.     

A tale of two negatives: differential memory modulation by threat-related facial expressions

Facial expressions serve as cues that encourage viewers to learn about their immediate environment. In studies assessing the influence of emotional cues on behavior, fearful and angry faces are often combined into one category, such as "threat-related," because they share similar emotional valence and arousal properties. However, these expressions convey different information to the viewer. Fearful faces indicate the increased probability of a threat, whereas angry expressions embody a certain and direct threat. This conceptualization predicts that a fearful face should facilitate processing of the environment to gather information to disambiguate the threat. Here, we tested whether fearful faces facilitated processing of neutral information presented in close temporal proximity to the faces. In Experiment 1, we demonstrated that, compared with neutral faces, fearful faces enhanced memory for neutral words presented in the experimental context, whereas angry faces did not. In Experiment 2, we directly compared the effects of fearful and angry faces on subsequent memory for emotional faces versus neutral words. We replicated the findings of Experiment 1 and extended them by showing that participants remembered more faces from the angry face condition relative to the fear condition, consistent with the notion that anger differs from fear in that it directs attention toward the angry individual. Because these effects cannot be attributed to differences in arousal or valence processing, we suggest they are best understood in terms of differences in the predictive information conveyed by fearful and angry facial expressions.
