ABSTRACTDifferences in eye movement patterns are often found when comparing passive viewing paradigms to actively engaging in everyday tasks. Arguably, investigations into visuomotor control should therefore be most useful when conducted in settings that incorporate the intrinsic link between vision and action. We present a study that compares oculomotor behaviour and hazard reaction times across a simulated driving task and a comparable, but passive, video-based hazard perception task. We found that participants scanned the road less during the active driving task and fixated closer to the front of the vehicle. Participants were also slower to detect the hazards in the driving task. Our results suggest that the interactivity of simulated driving places increased demand upon the visual and attention systems than simply viewing driving movies. We offer insights into why these differences occur and explore the possible implications of such findings within the wider context of driver training and assessment. 相似文献

ABSTRACTThe image on our retina changes every time we make an eye movement. To maintain visual stability after saccades, specifically to locate visual targets, we may use nontarget objects as “landmarks”. In the current study, we compared how the presence of nontargets affects target localization after saccades and during sustained fixation. Participants fixated a target object, which either maintained its location on the screen (sustained-fixation trials), or displaced to trigger a saccade (saccade trials). After the target disappeared, participants reported the most recent target location with a mouse click. We found that the presence of nontargets decreased response error magnitude and variability. However, this nontarget facilitation effect was not larger for saccade trials than sustained-fixation trials, indicating that nontarget facilitation might be a general effect for target localization, rather than of particular importance to post-saccadic stability. Additionally, participants’ responses were biased towards the nontarget locations, particularly when the nontarget-target relationships were preserved in relative coordinates across the saccade. This nontarget bias interacted with biases from other spatial references, e.g., eye movement paths, possibly in a way that emphasized non-redundant information. In summary, the presence of nontargets is one of several sources of reference that combine to influence (both facilitate and bias) target localization. 相似文献

This paper was the Mary Hemingway Rees Memorial Lecture, delivered at the XXIst World Assembly for Mental Health, Vancouver, Canada, 2001. The author had recently completed a period of appointment as the New Zealand Commissioner for Mental Health. In this lecture, the author puts in a moving plea - as a survivior of mental illness - for considering both spirituality and mental health in terms of the experience of the self. She talks about the value of communication particularly by sharing experiences via personal stories. The author goes on to contrast communication and control, and to emphasize the importance of making space in order to accept our own and others' imperfections and vulnerabilities. Attention is drawn to the work of Baruk (1978, 1998, 1999, 2000). She also discusses the way in which mental illness can lead to spiritual progress, and ultimately to mental health. The original version of the talk contained further pictorial illustrations; for technical reasons it would be difficult to reproduce all of them here in the journal. Most of the illustrative material consisted of photographs by the author, including the two photographs that are reproduced in this paper. 相似文献

Younger and older adults were asked to remember noun pairs (e.g., head – cap), verb pairs (e.g., bounce – throw), and verb-noun pairs (e.g., break – stick). For half of the pairs, participants used imagined objects and performed an action or series of related actions for each pair. For the other half of the pairs, participants read but did not perform the pairs. Free recall and cued recall tests revealed that age differences in memory for both performed and nonperformed items were larger for verbs than for nouns. The recall advantage of nouns over verbs was larger for older than for younger adults. Verbs are hypothesized to be more difficult for older adults to remember because they are more and less specific than nouns and because it is more difficult to integrate verbs with other words than to integrate nouns with other words. 相似文献

ABSTRACT A challenge in habitual prospective memory tasks (e.g., taking medication) is remembering whether or not one has already performed the action. Einstein, McDaniel, Smith, and Shaw (1998, Psychological Science, 9, 284) showed that older adults were more likely to incorrectly repeat an action on habitual prospective memory tasks. Extending this research, we (a) biased participants either toward repetition or omission errors, (b) investigated whether performing a more complicated motor action can reduce repetition errors for older adults, and (c) examined participants' resource allocation to the prospective memory task. Older adults committed more repetition errors than younger adults regardless of biasing instructions when ongoing task demands were challenging (Experiment 1). Performing the more complex motor action, however, reduced repetition errors for older adults. Further, when the ongoing task was less demanding, older adults' repetition errors declined to levels of younger adults (Experiment 2). Consistent with this finding, the resource allocation profiles suggested that older participants were monitoring their output (prospective memory execution) in each trial block. 相似文献

The purpose of this study was to examine the level of fears in Swedish children and to examine the relation of those fears to state and trait anxiety. The purpose was also to do a normative study of FSSC-R (Fear Survey Schedule for Children - Revised). In total, 550 children between 8 and 16 years of age answered the questionnaires. The results indicate that there are no gender differences in total fear score, factor scores and number of fears. In contrast to earlier results, there was no correlation between fear and trait anxiety; however, a modest correlation was found between fear and state anxiety 相似文献

When people believe that their higher performance poses a threat to another person, they may experience discomfort or concern that has been termed Sensitivity to being the Target of a Threatening Upward Comparison (STTUC). One way to reduce STTUC discomfort might be to avoid contact with the outperformed person, a possibility examined in three studies of undergraduates. In laboratory contexts, STTUC discomfort predicted reluctance to meet an outperformed peer (Study 1) and preference for a different partner in future competitions (Study 2). In Study 3, which focused on naturalistic outperformance situations, STTUC distress again predicted avoidance. Additionally, avoidance of contact predicted less satisfaction with outcomes, especially in relationships where people knew each other well. 相似文献

The prosocial behavior of 76 male and female fourth-graders was investigated by observing their sharing, caring, and helping actions on the playground and by obtaining sociometric measures (peer nomination) of a variety of prosocial actions. Interrelations among all the prosocial acts were examined. Personal characteristics such as assertiveness, empathy, self-concept, value orientation, and moral-motivational reasoning based on role taking were also assessed. The number and pattern of significant correlations obtained among the observed prosocial behaviors, among the peer nominations, and between these two sets of scores indicated that, for girls, prosocial responding was moderately coherent, but that, for boys, caring, sharing, and helping were relatively independent domains. The hypotheses about the associations between prosocial behavior and personal characteristics were at least moderately supported. Sex differences in these relationships suggest that females' predominant prosocial responses reflect expressiveness and caring, whereas males' most salient prosocial responses are more active and instrumental. 相似文献

Recently, researchers have discovered that individuals who are consistent timers in a tapping task are not necessarily consistent timers when they perform a continuous drawing task. In other words, nonsignificant correlations were found among tapping and drawing movements for timing precision (S. D. Robertson et al., 1999). In the present experiment, the authors investigated whether or not consistency in timing for tapping and drawing was correlated when participants (N = 24) were allowed to move at their preferred rate of movement. There were no significant correlations between tapping and drawing in terms of timing precision. That result lends further support to the notion that timing behavior is specific to the nature of the task, and thus further weakens the idea that timing is a generalized ability that can be imposed on a variety of different types of tasks. 相似文献
