In this event-related fMRI study, brain activity patterns were compared in extensive groups of young (N=25) and older (N=38) adults, while they were performing a word stem completion priming task. Based on behavioral findings, we tested the hypothesis that aging affects only the lexical/semantic, but not the perceptual component of word stem priming. To this end, we distinguished between priming-related activity reductions in posterior regions involved in visual processing, and regions associated with lexical/semantic retrieval processes, i.e., left lateral temporal and left prefrontal regions. Both groups revealed significant priming-related response time reductions. However, in accordance with earlier findings, a larger priming effect was found in the group of young participants. In line with previous imaging studies, the groups showed common priming-related activity reductions in the anterior cingulate, and the left inferior prefrontal cortex extending into the anterior portion of the left superior temporal gyrus, and at lower thresholds also in the right occipital lobe. However, when directly comparing the groups, greater priming-related reductions were found for the young group in the left anterior superior temporal gyrus and the right posterior occipital lobe. These findings suggest that, converse to current psychological views, aging affects both perceptual and lexical/semantic components of repetition priming. 相似文献

In Dutch noun phrases like “het boek” (the book) or “de kat” (the cat), the definite article (het or de) depends on the noun's grammatical gender (neuter or non-neuter). Schriefers reported that the production of a noun phrase
like “het rode bed” (“the red bed”) in response to a colored picture takes less time when the picture is accompanied by a distractor word of
congruent gender (e.g., “huis,” a het-word) than when it is accompanied by a word of incongruent gender (e.g., “hand,” a de-word). In three experiments we explored the characteristics of this gender-congruency effect. The following conclusions were
reached. First, the gender-congruency effect is a rather robust phenomenon. Second, with the exception of a small effect in
Exp. 2, no evidence was obtained for a gender-congruency effect when subjects were required to produce a single noun in response
to a picture (e.g., “bed”). Third, the gender-congruency effect decreases with a decreasing familiarity of the distractor word. Implications for models
of word production are discussed.

Distinguishing Between Perceived Behavioral Control and Self-Efficacy in the Domain of Academic Achievement Intentions and Behaviors 总被引:1,自引:0,他引:1

We examined whether perceived behavioral control (PBC) and self-efficacy (S-E) can be distinguished empirically, and whether they make different contributions to the prediction of intentions and behavior. The behavioral criterion was performance in 3 high-school examinations. Measures of attitude, subjective norm, PBC, S-E, and intention were taken before the examinations. Grade achieved served as the behavioral measure. Factor analysis of items intended to measure PBC and S-E extracted 2 factors: confidence in ability to achieve the behavioral outcome, and belief that the outcome can be influenced by own efforts. Scores on these factors were labeled S-E and perceived control, respectively. Behavior was predicted better by S-E than by intentions, and intentions were more closely related to S-E than to attitudes, subjective norms, or perceived control. 相似文献

Reading interventions were applied in a brief multielement format to examine their effectiveness at improving the oral reading fluency of three students referred for reading problems. Although each student had different profiles across experimental analyses, effective interventions were identified and a mini-replication confirmed the pattern of results in each case. 相似文献

Prior research has examined killing behavior using a paradigm in which participants believe (falsely) that they are killing bugs. This work suggests that killing behavior escalates. In the present study, we sought to replicate the basic escalation effect within‐subjects. Further, in doing so, we controlled for experimenter “sanctioning” of killing that may have differed with key between‐subjects manipulations in the prior research. To control for this possible confound, the present experiment held experimenter instructions constant and examined whether killing naturally escalated within‐subjects across two 12‐sec bug‐killing tasks. Additionally, to verify that escalation is due to killing per se and not just physical practice of the procedure, we manipulated whether the procedure was described as real killing or simulated killing. Results showed that when participants thought they were killing bugs, the number of bugs put into the grinder increased from the first to the second killing task. No such escalation occurred when participants performed the procedure while knowing the killing was simulated. Thus, killing of bugs escalates and is not simply a consequence of perceived sanctioning of killing by an experimenter or simulated practice of the procedure. 相似文献

Two studies examined the relationship between women's insecurity-arousing comparisons with female models and shoe/handbag ownership. Idealized media images appear capable of threatening some women's sense of attractiveness and it may be that as a result, accessorizing becomes particularly appealing because it helps increase physical attractiveness without drawing attention to one's figure, the object of the threatening comparisons. In Study 1 (N=922), a correlational study, the more women reported that they feel insecure when they see attractive female models, the more shoes they tended to own. In Study 2 (N=286), we manipulated whether women saw images of attractive female models or not. The more women exhibited insecurity following exposure to the images of attractive models, the more shoes and handbags they tended to own. In both studies, these effects did not hold for ownership of trousers, an item of clothing that draws attention toward one's body. 相似文献

ABSTRACT According to the inhibition-deficit hypothesis age differences in working memory capacity and fluid intelligence have been attributed to a decline in inhibitory efficiency. Conceptualizing inhibition as multifaceted, 88 participants (49 younger and 39 elderly) completed two versions of the negative priming paradigm (identification and localization), and two variants of the directed forgetting paradigm (listwise and itemwise). Two tasks of the Wechsler Intelligence Test with high loadings on general fluid intelligence (Gf) served as validation criteria. Results revealed task-specific and speed-independent inhibitory deficits in the elderly (lower negative priming in both paradigms; more intrusions in the directed forgetting tasks), as well as higher levels of repetition priming. Significant correlations between measures of inhibition and the Wechsler scores were found in both age groups. Results support the view of multiple inhibitory-like capabilities that play a central role in the decline of higher-order cognitive functions in old age. 相似文献

We investigated the relationship between masculine honor beliefs and perceptions of the candidates vying for the presidency. Consistent with hypotheses, we found that higher levels of masculine honor beliefs were associated with more positive perceptions of Donald Trump and with more negative perceptions of Hillary Clinton. Furthermore, our results indicate that higher levels of masculine honor beliefs were associated with clear preferences for Donald Trump. Thus, our data, collected immediately prior to the election likely reflect the beliefs and perceptions that individuals took with them to the polls and help to explain the decisions that voters made on Election Day. 相似文献

A great deal of what we know about the world has not been learned via first-hand observation but thanks to others' testimony. A crucial issue is to know which kind of cues people use to evaluate information provided by others. In this context, recent studies in adults and children underline that informants' facial expressions could play an essential role. To test the importance of the other's emotions in vocabulary learning, we used two avatars expressing happiness, anger or neutral emotions when proposing different verbal labels for an unknown object. Experiment 1 revealed that adult participants were significantly more likely than chance to choose the label suggested by the avatar displaying a happy face over the label suggested by the avatar displaying an angry face. Experiment 2 extended these results by showing that both adults and children as young as 3 years old showed this effect. These data suggest that decision making concerning newly acquired information depends on informant's expressions of emotions, a finding that is consistent with the idea that behavioural intents have facial signatures that can be used to detect another's intention to cooperate. 相似文献
