If priming effects serve an adaptive function, they have to be both robust and flexible. In four experiments, we demonstrated
regular evaluative-priming effects for relatively long stimulus-onset asynchronies, which can, however, be eliminated or reversed
strategically. When participants responded to both primes and targets, rather than only to targets, the standard congruity
effect disappeared. In Experiments 1a–1c, this result was regularly obtained, independently of the prime response (valence
or gender classification) and the response mode (pronunciation or keystroke). In Experiment 2, we showed that once the default
congruity effect was eliminated, strategic-priming effects reflected the statistical contingency between prime valence and
target valence. Positive contingencies produced congruity, whereas negative contingencies produced equally strong incongruity
effects. Altogether, these findings are consistent with an adaptive-cognitive perspective, which highlights the role of flexible
strategic processes in working memory as opposed to fixed structures in semantic long-term memory or in the sensorimotor system. 相似文献

The present study examined the role of controlled attention in age differences in event-based prospective memory performance across adolescence. The researchers tested whether presenting the prospective memory cue in or out of focal awareness of the ongoing task (resulting in low versus high demands for controlled attention, respectively) might affect age-related prospective memory performance. In total, 119 Chinese participants ages 13 to 20 took part in this study (60 adolescents: age M = 13.26 years, SD = 0.50; 23 boys; 59 young adults: age M = 19.70 years, SD = 0.87; 19 men). Findings demonstrated a significant interaction, F(1, 114) = 6.41, p < .05. No effect of age on prospective memory performance was revealed when a focal cue was used (F < 1), whereas there was a reliable age effect between adolescents and young adults when nonfocal prospective memory cues were presented, F(1, 59) = 16.13, p < .01. This pattern of results suggests that the interplay of both available resources of controlled attention and working memory, along with specific task demands, may contribute to possible age differences in prospective memory performance across adolescence. Results are discussed in the context of the multiprocess theory of prospective memory. 相似文献

Social change has accentuated various demands in people's work lives including, for instance, fears of being laid off, anticipated or experienced difficulties in finding a new and/or appropriate job or a lack of security in career planning. The present study on N = 1751 employed, short-term unemployed, and long-term (> 12 months) unemployed German adults examined the associations between the perceived accumulation of such demands and individuals' life satisfaction. Further, main and moderating effects of individuals' modes of dealing with these demands, that is, engagement and disengagement preferences based on Heckhausen and Schulz's (1995) life-span theory of control, were investigated. A higher load of demands was expected to be linked to lower life satisfaction irrespective of employment status. Positive main effects as well as buffering effects of engagement and disengagement, in contrast, were expected to differ depending on the particular employment situation. Multiple linear regressions including main and interaction effects set up as three-group comparison models showed that a high demand load was linked to lower life satisfaction in each of the three groups. Engagement was positively linked to life satisfaction in the case of employment, whereas in the transient stage of short-term unemployment, disengagement strengthened the negative link between demand load and life satisfaction. In the case of long-term unemployment, both modes of dealing with demands were positively related to life satisfaction. The positive effect of engagement, however, diminished as perceived demands increased, indicating that “over-engagement” may be counterproductive when faced with a high demand load. Consequences of our findings for potential interventions among unemployed people are discussed. 相似文献

Although fear of death features prominently in many historical and contemporary theories as a major motivational factor in religious belief, the empirical evidence available is ambivalent, and limited, we argue, by imprecise measures of belief and insufficient attention to the distinction between implicit and explicit aspects of cognition. The present research used both explicit (questionnaire) and implicit (single-target implicit association test; property verification) measurement techniques to examine how thoughts of death influence, specifically, belief in religious supernatural agents. When primed with death, participants explicitly defended their own religious worldview, such that self-described Christians were more confident that supernatural religious entities exist, while non-religious participants were more confident that they do not. However, when belief was measured implicitly, death priming increased all participants' beliefs in religious supernatural entities, regardless of their prior religious commitments. The results are interpreted in terms of a dual-process model of religious cognition, which can be used to resolve conflicting prior data, as well as to help explain the perplexing durability of religious belief. 相似文献

When participants are asked to respond in the same way to stimuli from different sources (e.g., auditory and visual), responses
are often observed to be substantially faster when both stimuli are presented simultaneously (redundancy gain). Different
models account for this effect, the two most important being race models and coactivation models. Redundancy gains consistent
with the race model have an upper limit, however, which is given by the well-known race model inequality (Miller, 1982). A number of statistical tests have been proposed for testing the race model inequality in single participants and groups
of participants. All of these tests use the race model as the null hypothesis, and rejection of the null hypothesis is considered
evidence in favor of coactivation. We introduce a statistical test in which the race model prediction is the alternative hypothesis.
This test controls the Type I error if a theory predicts that the race model prediction holds in a given experimental condition. 相似文献

The ability to anticipate future states of perceived actions is an important faculty for motor control and the generation of coordinated social interaction. Here, we studied whether the perception of a static posture of a complex movement automatically activates representations of future states of this particular movement event. We did this by using a priming paradigm with photographs of a high-jump movement. Participants judged whether a picture depicted a posture from the approach or flight phase of that movement. To evaluate expertise-dependent effects of priming, non-athletes and athletes were compared. Results revealed faster responding when prime and target pictures were assigned to the same motor response (response priming), and when the temporal order of prime and target matched the temporal order of the depicted postures in a real high jump (temporal-order priming). Whereas experts showed a temporal-order effect even within the same response category, such an effect occurred for novices only between response categories. A second experiment confirmed that these between-group differences are due to domain-specific motor expertise (i.e., high jump) rather than to general motor experiences. Altogether our results suggest that motor expertise results in a more fine-grained posture-based movement representation. 相似文献

Models of decision making postulate that interactions between contextual conditions and characteristics of the decision maker determine decision-making performance. We tested this assumption by using a possible positive contextual influence (goals) and a possible negative contextual influence (anchor) in a risky decision-making task (Game of Dice Task, GDT). In this task, making advantageous choices is well known to be closely related to a specific decision maker variable: the individual level of executive functions. One hundred subjects played the GDT in one of four conditions: with self-set goal for final balance (n?=?25), with presentation of an anchor (a fictitious Top 10 list, showing high gains of other participants; n?=?25), with anchor and goal definition (n?=?25), and with neither anchor nor goal setting (n?=?25). Subjects in the conditions with anchor made more risky decisions irrespective of the negative feedback, but this anchor effect was influenced by goal monitoring and moderated by the level of the subjects' executive functions. The findings imply that impacts of situational influences on decision making as they frequently occur in real life depend upon the individual's cognitive abilities. Anchor effects can be overcome by subjects with good cognitive abilities. 相似文献

Prior research indicates that, in some circumstances, reminders may facilitate prospective remembering. However, it remains unclear whether this effect is dependent on the initiation source (self vs. external), whether it is moderated by task type (event vs. time based), or whether the provision of standardized reminders particularly benefits older adults. In the current study, young (n?=?48) and older adults (n?=?47) were tested on a laboratory-based prospective memory task in which they encountered three counterbalanced reminder conditions: no reminders, self-initiated reminders, and experimenter-initiated reminders. The results indicated that while the provision of reminders enhanced prospective memory performance, no difference was seen between self-initiated and experimenter-initiated reminder conditions, nor was there any interaction with age or prospective memory type (event vs. time based). These data support the role of both self- and externally generated external reminders as an aid to prospective remembering. However, the absence of any interaction with age is not consistent with theoretical models of ageing that consider the provision of such reminders to reduce strategic demands (or increase automatic processing). 相似文献
