Can Personal Values Predict Performance? Evidence in an Academic Setting

In this paper we briefly review the construct of personal values, and we examine whether achievement values may be incrementally related to performance beyond personality. We also consider the motivational processes that may mediate the relationships between characteristics of the individual (personality and values) and performance. In an academic setting, achievement values were related to course performance even after controlling for the relevant personality factors of Conscientiousness, Emotional Stability, and Extraversion. Further, motivational processes of goal content and goal striving mediated the relationships between individual characteristics (personality and values) and performance.     

Short-term retention of superimposed and of spatially distinct multiletter visual arrays

On each trial, Ss attempted to retain a series of five visually presented letters while concurrently “shadowing” (repeating aloud) a rapid series of aurally presented letters. If serial-position accuracy is ignored, they were able to store more than only the last letter of a typical series, even though all five letters appeared on the same screen, and that performance was superior to the retention of five auditorily presented letters. Together, these findings suggest that a form of visual storage might have been employed for the retention of visual stimuli and, specifically, one that was relatively immune to erasure as compared to “iconic” storage. In further support of that hypothesis, retention of such visual series as measured by free-recall accuracy was not inferior to that of five letters, each of which was presented on a separate screen.     

False memories of having said the unsaid: some new demonstrations

In a series of four studies, subjects who were naive as to the true purpose of the research were asked if they had said aloud things that, at most, they had only intended to say. Often, subjects reported (incorrectly) that they had said them. Specifically, the procedures involved: showing a series of phrases, each being followed by a command to say it aloud or not (Study 1); asking a series of questions, each being followed by a request to answer it aloud or not (Study 2); asking a series of questions in a public polling situation and interrupting the subject before one of the questions was answered (Study 3); and having each subject participate in a debate, during the course of which the participant was induced to plan to use a particular point, but was prevented from doing so (Study 4). Subjects were confident of such erroneous reports; they had a lower tendency to make such errors for material that had not actually been presented, and such errors depended upon certain details of the manner in which such ‘source-monitoring’ searches were initiated. © 1997 John Wiley & Sons, Ltd.     

Visual-illusion distance paradoxes: A resolution

Several illusory phenomena are susceptible to explanations that invoke size scaling, but only if the distance estimates used to compute size are allowed to contradict the estimates of distance that are consciously experienced at the same time. However, such ??paradoxes?? make sense within Milner and Goodale??s (2006) two-stream theory of vision.     

Time perspective, depression, and substance misuse among the homeless

Using the Zimbardo Time Perspective Inventory (ZTPI; P. G. Zimbardo & J. N. Boyd, 1999), the authors found that homeless people, in comparison with a control group, had a significantly more negative outlook concerning their past and present as evinced by high Past-Negative and Present-Fatalistic scores and low Past-Positive scores on the ZTPI. However, the homeless individuals were almost indistinguishable from control participants on measures of Present-Hedonism and Future thinking. The homeless individuals had significantly higher levels of depression, with 31 out of 50 (62%) reaching criteria for probable depression. However, this finding was unrelated to their atypical time perspective. There was no significant relation between substance misuse and time perspective. Despite their current difficulties, including depression and drug abuse, the homeless individuals maintained a propensity toward future thinking characterized by striving to achieve their goals.     

Factors influencing the temporal relationship between alcohol consumption and experiences with aggression among college women.

The authors assessed temporal relationships among alcohol use, aggression, and mood using daily data from 179 college women. Participants called an interactive voice response system over an 8-week period. The odds of experiencing verbal, sexual, and physical aggression (odd ratios = 2.25, 19.44, and 11.84, respectively) were significantly higher on heavy drinking days (M = 7.46 drinks) compared to nondrinking days. Both a history of victimization and greater psychological symptom severity influenced the odds of involvement in verbal aggression. The odds of alcohol consumption were 3 times higher during the 24 hr following verbal aggression compared with days in which verbal aggression did not occur. On the day immediately following involvement in either verbal or physical aggression, positive mood decreased and negative mood increased. During the week (2-7 days) following sexual aggression, women's positive mood was decreased. These findings reinforce the need for interventions aimed at reducing heavy episodic drinking on college campuses.     

Inadvertent plagiarism in young and older adults: The role of working memory capacity in reducing memory errors

Two experiments examined inadvertent plagiarism in young and older adults. Young and older adults took turns generating category exemplars in small groups, and after a short retention interval recall was tested and subjects were asked to generate new exemplars (i.e., exemplars not initially generated). When asked to generate new exemplars, older adults were more likely to repeat exemplars that had been generated earlier by others (i.e., generate-new plagiarism). When asked to recall the exemplars they had generated earlier, older adults were more likely to claim that they had generated exemplars that had been generated by others (i.e., recall-own plagiarism), and were also more likely to falsely recall exemplars that had not been generated at all. There were no age differences in confidence for items that were plagiarized on the generate-new task. Hierarchical regression analyses indicated that age differences in generate-new plagiarism and false recall were entirely mediated by measures of episodic recall and working memory capacity. We conclude that inadvertent plagiarism errors result from the failure of systematic decision processes, and that controlled attention is important for avoiding memory errors.     

Foveal-to-peripheral priming in letter identification reflects response bias, not enhanced visibility

Several studies have suggested that it might be easier to identify a letter when its replication is simultaneously presented in the visual display. We have measured identification accuracy for a memorized target letter that was shown in the peripheral field in two conditions in which a letter either identical or different in shape was flashed simultaneously at fixation. The results of three forced-choice experiments showed that, contrary to Geiger and Lettvin's (1986) previous findings, an identity prime did not improve the visibility of a temporally backward masked target letter. However, the foveal prime letter could apparently bias the subject's decision so that he/she was much more ready to report the more visible prime letter as the peripheral target.
