Cues reduce direction uncertainty and enhance motion detection

Previous work has shown that detectability of motion is better when the observer knows ahead of time the direction of that motion (“certainty”) than when he does not know the direction (“uncertainty”). We now report attempts to reduce this performance decrement associated with direction uncertainty. In these experiments, a briefly flashed, oriented line cued the observer to the direction of motion that might occur. When the cue appeared before the moving target, detectability increased; when the cue appeared after the moving target, performance dropped below that for no cue at all. In addition, we examined the effect of cue reliability, varying the relation between cue orientation and actual direction of target motion. The more accurate the cue is, the larger the performance increment. When the cue indicated a direction more than 90 deg from the actual target direction, performance was worse than when there was no cue. Results are discussed with regard to the feasibility of reducing uncertainty in real-world situations.     

Useful Field of View and Other Neurocognitive Indicators of Crash Risk in Older Adults

Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed.     

Semantic Profiles and Psychosexual Interests as Indicators of Identification

Identification patterns of male and female children (110 boys and 114 girls) in grades one through five were studied by two methods that have been used in “identification research”; identification inferred from sex-appropriate and sex-inappropriate games, preferences and identification inferred from profile congruence between “self,” “mother,” and “father” concepts on a semantic differential (SD). Results showed that the two measures are meaningfully related as “self” rating scales; however, there was no apparent association between the Games and Activities Inventory (GAI) (games preferences) and the SD as indicators of identification. The patterns of identification found using the SD were generally consistent with the theoretical formulation of identification proposed by Lynn (1959.)     

When focusing on differences leads to similar perspectives

The current research investigated whether mind-sets and contexts that afford a focus on self-other differences can facilitate perceptual and conceptual forms of perspective taking. Supporting this hypothesis, results showed that directly priming a difference mind-set made perceivers more likely to spontaneously adopt other people's visual perspectives (Experiment 1) and less likely to overimpute their own privileged knowledge to others (Experiments 2 and 3). Given that intergroup encounters typically evoke a difference mind-set, we also explored the possibility that such contexts might help perceivers to step outside their own perspectives. As predicted, perceivers were less "cursed" by their own privileged knowledge when mentalizing about out-group targets than when mentalizing about in-group targets (Experiment 4) and communicated more effectively with interaction partners whose minimal-group membership differed from their own (Experiment 5). Overall, acknowledging self-other differences allowed perceivers to look beyond the limits of their own perspectives and thereby provided an efficacious route to intuiting other people's minds.
