In two experiments (Experiment 1: N = 180, Experiment 2: N = 150), we investigated the anecdotal observation that school age children are assumed to be experts in spatial associate learning. In the first experiment, second graders, sixth graders, and adults learned the associations between 32 pictures and either a position or a word. 16 pictures had each to be associated with one position in a 4-by-4 grid of squares (spatial condition); the other 16 pictures had each to be associated to one of 16 monosyllabic words (verbal condition). After a 3 min distractor interval the associated position or word had to be retrieved with the pictures as cues. In Experiment 2, the results were replicated in principle with modifications in the experimental details. Performance improvement as a function of age turned out to be substantially larger in the verbal condition compared to the spatial one. The results are traced back to the idea that spatial associate learning is a cognitive function maturating early during life span.  相似文献

Previous studies found that caffeine consumers acquired a liking for the flavour of novel caffeinated drinks when these drinks were consumed repeatedly in a caffeine-deprived, but not nondeprived, state. Expression of this acquired liking appeared acutely sensitive to current caffeine deprivation state, but the use of between-subjects designs confounded interpretation of those studies. The present study evaluated these findings further using a within-subject design, with one flavour paired with caffeine (CS + ) and the second with the absence of caffeine (CS-). During four CS + and four CS- training days, 32 moderate caffeine consumers alternatively consumed a novel flavoured drink a CS + paired with caffeine and a CS- flavour paired with placebo. Participants evaluated both drinks before and after training in two motivational states: caffeine deprived and nondeprived. As predicted, pleasantness ratings for the caffeine-paired flavour increased overall. However, this acquired liking was only significant when tested in a caffeine-deprived state. These data are consistent with a conditioned-flavour preference model and imply that expression of acquired liking for a novel caffeinated flavour depends on the need for the effects of caffeine at the time when the drink is evaluated.  相似文献

Christian Fundamentalists used to read the apocalyptic scenario through the “red” filter of communism, but since the 1980s the target has shifted to the “green tide” of Islam. One of the more colorful Fundamentalist diatribes against Islam is cartoon evangelist Jack Chick’s The Prophet, a comic book that calls Islam a Satanic plot hatched by the Catholic church. This article examines the rhetoric of Christian Fundamentalist diatribe against Islam in light of apocalyptic scenarios drawn out of biblical prophecy. Chick’s comic and the millenarian Hal Lindsay’s The Late Great Planet Earth are placed in the context of doctrinal attacks on Islam in medieval Christendom. In tracing the usage of “Islamic fundamentalism,” I argue that the term “fundamentalism” is problematic for cross-cultural studies of religious expression and movements.

Everyday social interaction is often dominated by categorical thinking, with generic group‐based knowledge structures guiding people's dealings with others. Noting the important influence that category‐cueing facial features exert during the initial stages of person construal, the current work explored the effects of hair cues on the process and temporal dynamics of sex categorization. Using a standard priming paradigm to index the products of person construal (i.e., categorical and stereotype‐ based knowledge), the results of three experiments revealed that: (i) hair cues alone are sufficient to trigger category and stereotype activation; and (ii) during the early stages of person perception, these cues have the capacity to reverse conventional priming effects and generate errors of categorical assignment (e.g., female faces prime male knowledge). These findings are considered in the context of contemporary accounts of person construal. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Although it has been suggested that the delayed realization of intended actions should benefit from appropriate intention planning, empirical evidence on this issue is scarce. In three experiments, we examined whether and which planning aids provided in the intention formation phase affect delayed intention realization in young and old adults. One finding was that intention planning directly affected delayed intention realization: instructing participants to include the cue for appropriate intention initiation in their plans benefited delayed performance. Another finding was that older adults' performance was improved when they were guided in structuring their plan in combination with guidance in implementing this plan after a delay. In sum, the results point to the importance of plan-related factors for understanding the delayed realization of intended actions.  相似文献

The present study examined the association between neuropsychological behavioral performance and psychopathic personality traits, measured via the Psychopathic Personality Inventory (PPI), in a non-incarcerated sample. Specifically, performance involving general executive cognitive functioning (ECF) and response inhibition was investigated in regards to the two main psychopathy factors (affective-interpersonal and social deviance) of the PPI. A group of 95 student volunteers were administered the PPI and a variety of neuropsychological measures. Analyses revealed that total PPI scores were related to deficits in response inhibition but not general ECF. However, this relationship was qualified by the differential associations observed for the two PPI factors. The social deviance factor was associated with deficits in general ECF and response inhibition, whereas the affective-interpersonal facet was associated with enhanced general ECF performance but not response inhibition. The results suggest that cognitive functioning shows predicted associations with a self-report measure of psychopathy among non-incarcerated young adults, providing further evidence for psychopathy conceptualizations from a normal-range personality perspective.  相似文献

Two hundred and thirty‐four persons were surveyed to assess personality aspects (action versus state orientation, need for cognition, faith in intuition) and emotional aspects of their attitudes towards the NATO military intervention in the Kosovo war in the spring of 1999. Additionally, in an imagined scenario they were asked to decide whether they would sign a petition addressed to the German government protesting against military intervention. Three ways of dealing with this decision were differentiated: (1) decisive action, (2) avoiding the decision conflict, and (3) elaborating the decision problem with the goal of building up feelings to guide action (amplification). Correlations between the variables were evaluated using path analysis in order to predict the decision strategy from personality dimensions and attitude variables (ambivalence, involvement). High action orientation caused low attitude ambivalence and high personal involvement in the topic. Strong ambivalence prevented swift action and supported a tendency towards elaboration and amplification of feelings. Involvement had a favorable effect on action readiness and a negative effect on conflict‐avoiding strategies. Moreover, it moderated the effects of ambivalence on the preference for conflict management strategies. The results confirm theoretical approaches that stress the importance of affect for acting and deciding. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

The modulatory influence of literacy on the cognitive system of the human brain has been indicated in behavioral, neuroanatomic, and functional neuroimaging studies. In this study we explored the functional consequences of formal education and the acquisition of an alphabetic written language on two- and three-dimensional visual naming. The results show that illiterate subjects perform significantly worse on immediate naming of two-dimensional representations of common everyday objects compared to literate subjects, both in terms of accuracy and reaction times. In contrast, there was no significant difference when the subjects named the corresponding real objects. The results suggest that formal education and learning to read and to write modulate the cognitive process involved in processing two- but not three-dimensional representations of common everyday objects. Both the results of the reaction time and the error pattern analyses can be interpreted as indicating that the major influence of literacy affects the visual system or the interaction between the visual and the language systems. We suggest that the visual system in a wide sense and/or the interface between the visual and the language system are differently formatted in literate and illiterate subjects. In other words, we hypothesize that the pattern of interactions in the functional-anatomical networks subserving visual naming, that is, the interactions within and between the visual and language processing networks, differ in literate and illiterate subjects.  相似文献

The Illness Intrusiveness Rating Scale (IIRS) is a measure designed to assess the impact of illness on various domains of functioning (G. M. Devins, 1994). In anxiety disordered patients, illness intrusiveness ratings are higher than those of chronically ill medical patients, suggesting that the IIRS may have a different underlying structure in a sample of individuals with anxiety disorders. To examine this possibility, IIRS items were submitted to an exploratory and confirmatory factor analysis in 2 samples (total N = 294). These solutions were compared to solutions in chronically ill populations from a previous study. In the exploratory analysis, both a one-factor and a three-factor solution were identified, accounting for 42 and 61% of the variance, respectively. Confirmatory analyses showed adequate similarity between the three-factor structure of the IIRS from a medically ill population and the current three-factor structure, suggesting that elevated IIRS scores in anxiety disordered samples cannot be explained simply by a different structure of the instrument.  相似文献
