ABSTRACTIn recent years there has been rapid proliferation of studies demonstrating how reward learning guides visual search. However, most of these studies have focused on feature-based reward, and there has been scant evidence supporting the learning of space-based reward. We raise the possibility that the visual search apparatus is impenetrable to spatial value contingencies, even when such contingencies are learned and represented online in a separate knowledge domain. In three experiments, we interleaved a visual choice task with a visual search task in which one display quadrant produced greater monetary rewards than the remaining quadrants. We found that participants consistently exploited this spatial value contingency during the choice task but not during the search task – even when these tasks were interleaved within the same trials and when rewards were contingent on response speed. These results suggest that the expression of spatial value information is task specific and that the visual search apparatus could be impenetrable to spatial reward information. Such findings are consistent with an evolutionary framework in which the search apparatus has little to gain from spatial value information in most real world situations. 相似文献

ABSTRACT To investigate the relationship between visual acuity and cognitive function with aging, we compared low-vision and normally-sighted young and elderly individuals on a spatial working memory (WM) task. The task required subjects to memorise target locations on different matrices after perceiving them visually or haptically. The haptic modality was included as a control to look at the effect of aging on memory without the confounding effect of visual deficit. Overall, age and visual status did not interact to affect WM accuracy, suggesting that age does not exaggerate the effects of visual deprivation. Young participants performed better than the elderly only when the task required more operational processes (i.e., integration of information). Sighted participants outperformed the visually impaired regardless of testing modality suggesting that the effect of the visual deficit is not confined to only the most peripheral levels of information processing. These findings suggest that vision, being the primary sensory modality, tends to shape the general supramodal mechanisms of memory. 相似文献

Based on Diener's (Diener, E. (1984). Subjective well-being. Psychological Bulletin, 95, 542–575.) tripartite model of subjective well-being (SWB), subjective evaluations of past, present, and anticipated future life satisfaction (LS), positive affect (PA), and negative affect (NA) were evaluated in a cross-sectional undergraduate sample. Upward mean trends in subjective trajectories (past?<?present?<?future) were typical, on average, for each SWB component. As predicted, higher levels of present SWB were aligned with greater positive psychological, physical, and interpersonal functioning. In contrast, steeper upward subjective SWB trajectories were associated with greater distress and dysfunction. Of the three SWB components, unique links with indicators of functioning were most consistent for LS trajectories. We conclude that a temporally expanded conceptualization of SWB spanning subjective assessments of past, present, and anticipated future LS, PA, and NA provides a rich framework for studying the structure of SWB and the significance of how people perceive their well-being to be unfolding over time. 相似文献

Poor decision making during adolescence occurs most frequently when situations
are emotionally charged. However, relatively few studies have measured the
development of cognitive control in response to emotional stimuli in this
population. This study used both affective (emotional faces) and non-affective
(letter) stimuli in two different flanker tasks to assess the ability to ignore
task-irrelevant but distracting information, in 25 adults and 25 adolescents. On
the non-emotional (letter) flanker task, the presence of incongruent flanking
letters increased the number of errors, and also slowed participants’ ability to
identify a central letter. Adolescents committed more errors than adults, but
there were no age-related differences for the reaction time interference effect
in the letter condition. Post-hoc testing revealed that age-related differences
on the task were driven by the younger adolescents (11-14 years); adults and
older adolescents (15-17 years) were equally accurate in the letter condition.
In contrast, on the emotional face flanker task, not only were adolescents less
accurate than adults but they were also more distracted by task-irrelevant
fearful faces as evidenced by greater reaction time interference effects. Our
findings suggest that the ability to self-regulate in adolescents, as evidenced
by the ability to suppress irrelevant information on a flanker task, is more
difficult when stimuli are affective in nature. The ability to ignore irrelevant
flankers appears to mature earlier for non-affective stimuli than for affective
stimuli. 相似文献

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning. 相似文献

Why is risk consistently underestimated, and why do young men in particular take exceptionally high risks and think of themselves as invulnerable? Two explanatory paths are proposed. The first is that risk taking in young males has been shaped by evolutionary forces to provide a fitness value. The second pathway is through myth and the other narrative forms that affirm the ego's immortality and invulnerability. Because of its evolutionary base, risk taking is emotionally driven: Emotions are preverbal and irrational, which means that persuasive prevention cannot be more than weakly successful. Three prevention challenges emerge from this analysis: to determine what it is that young drivers fear, to attach affectively experienced fears to defined driving behaviors, and to devise injury-prevention programs that acknowledge that young males' risk taking is not "stupid," but driven by adaptive needs that are as significant to today's young adults as they were to our distant ancestors. 相似文献

We investigated the sibling relationship as a context for cognitive development. Forty preschoolers (ages 5–6) and their younger siblings (ages 2–3) were visited at home. Four games were presented to the older siblings and they were asked (a) to estimate how well their younger sibling will perform on each game and (b) to teach the younger sibling how to use the games. The older siblings' mediating behaviours during the teaching session and the younger siblings' performance on the four tasks were coded. The frequency of mediating behaviours—including attention focusing, amplifying affect and providing meaning, fostering a sense of competence, regulating of the learning process, de‐contextualization, and negative feedback in the form of mocking and laughing at errors, predicted the younger siblings' task performance. The older sibling's accurate perception of the younger child's competence was uniquely predictive of task performance. The highest amount of mediation was observed in older‐brother–younger‐brother pairs, in particular the behaviours of negative feedback and amplifying affect. Results contribute to the discussion on the role of siblings as moderators of cognitive development and are discussed in terms of Vygotsky's cultural–historical perspective on apprenticeship.

Children's perceptions of parental discipline methods and their perceptions of child gender differences in their parents' choices of discipline methods were assessed. One hundred and seventy 8‐year‐old children (78 boys, 92 girls) in two‐parent families were asked about disciplinary behaviour in five transgression situations. The results pointed to gender differences when the children were talking about themselves. Boys believed that they would receive more physical punishment, milder requests and less induction than girls. Children also indicated that their parents would choose a different response if they (themselves) were of the other sex. Both boys and girls reported that their parents would treat boys more severely than they would girls. The results showed that the responses of those children with a sibling of the other sex did not reveal any gender‐differentiated experience of their parents' discipline strategies.
