This study explored the applicability of previous research (obtained with groups of college-educated women) about the subjective experience of aging in midlife to men and less-educated people. Two-hundred fifty-nine men and women who graduated from a public high school in 1955-1957 retrospectively assessed their feelings of identity certainty, confident power, generativity, and concern about aging for their 60s, 40s, and 20s. Participants reported higher levels of identity certainty, confident power, and concern about aging at each age, and a leveling off of generativity in their 60s. There were some gender and social class differences. Although men and women recalled the same trajectory of these feelings, men reported higher levels of identity certainty and confident power across age. Non-college-educated men recalled the highest levels of concern about aging across age. We discuss how these findings add to our understanding of the experience of aging in these domains. 相似文献

This study examined the association between organization of knowledge about a romantic partner (partner structure) and relationship status (ongoing or ended) 1 year later. Ironically, partner structures that were associated with more positive feelings about one's partner at Time 1 were associated with greater rates of breakup by Time 2. These results are interpreted in terms of the vulnerability of compartmentalized partner structures to shifts in the salience of negative beliefs and the hypothesized difficulty of maintaining integrative structures for an extended period of time. Change in partner structure during 1 year's time was consistent with the predictions of the dynamic model that evaluative integration should increase when negative beliefs become salient. Such change (which may represent a transient shift) was associated with couples' longevity when relationship conflict was low, supporting the view that integration reflects a struggle with negative attributes that may or may not be successful. 相似文献

We summarize five studies of our large-scale research program, in which we examined aspects of contour-based object identification
and segmentation, and we report on the stimuli we used, the norms and data we collected, and the software tools we developed.
The stimuli were outlines derived from the standard set of line drawings of everyday objects by Snodgrass and Vanderwart (1980).
We used contour curvature as a major variable in all the studies. The total number of 1,500 participants produced very solid,
normative identification rates of silhouettes and contours, straight-line versions, and fragmented versions, and quite reliable
benchmark data about saliency of points and object segmentation into parts. We also developed several software tools to generate
stimuli and to analyze the data in nonstandard ways. Our stimuli, norms and data, and software tools have great potential
for further exploration of factors influencing contour-based object identification, and are also useful for researchers in
many different disciplines (including computer vision) on a wide variety of research topics (e.g., priming, agnosia, perceptual
organization, and picture naming). The full set of norms, data, and stimuli may be downloaded fromwww.psychonomic.org/archive/. 相似文献

This study examined the organization of self-knowledge, with special attention to beliefs about physical appearance, in three groups of college-aged women: high body dissatisfaction with symptoms of disordered eating; high body dissatisfaction with no symptoms of disorder; and low body dissatisfaction. In the nondisordered, dissatisfied group, negative beliefs about physical appearance were organized in the self-structure in a way that isolated those beliefs and might minimize their impact and importance. This group also displayed adaptive types of self-concept organization (evaluative integration for those with important negative self-beliefs and compartmentalization for those with important positive beliefs) and effective coping strategies. Features of self-structure that characterize the nondisordered,dissatisfied group may provide a useful model for helping individuals with disordered eating cope with their negative physical appearance beliefs. 相似文献

Uneconomical choices by humans or animals that evaluate reward options challenge the expectation that decision-makers always
maximize the return currency. One possible explanation for such deviations from optimality is that the ability to sense differences
in physical value between available alternatives is constrained by the sensory and cognitive processes for encoding profitability.
In this study, we investigated the capacity of a nectarivorous bat species (Glossophaga commissarisi) to discriminate between sugar solutions with different concentrations. We conducted a two-alternative free-choice experiment
on a population of wild electronically tagged bats foraging at an array of computer-automated artificial flowers that recorded
individual choices. We used a Bayesian approach to fit individual psychometric functions, relating the strength of preferring
the higher concentration option to the intensity of the presented stimulus. Psychometric analysis revealed that discrimination
ability increases non-linearly with respect to intensity. We combined this result with a previous psychometric analysis of
volume perception. Our theoretical analysis of choice for rewards that vary in two quality dimensions revealed regions of
parameter combinations where uneconomic choice is expected. Discrimination ability may be constrained by non-linear perceptual
and cognitive encoding processes that result in uneconomical choice. 相似文献

Participants were presented with sentences mentioning an entity with a typical location in the upper or lower vertical space (e.g., roof vs. root). Sentences supported or reversed the typical location of the target entity. Sensibility judgments requiring upwards or downwards responses were faster when the response matched rather than mismatched the target entity's typical location. This compatibility effect was independent of whether the sentence context supported or reversed the target entity's typical location. The results, therefore, provide clear evidence for word-based but no evidence for sentence-based simulation processes. 相似文献

Resource control and status as stimuli for arousing power motivation: An American-Chinese comparison
In this paper, we analyze power motivation from a cross-cultural perspective. Power motivation has been mainly studied within
the Western culture. However, previous research suggests that some contours and nuances of power and power motivation may
be culturally specific. In this article, we analyze cultural differences between American and Chinese students in how power
motivation is aroused. Drawing from the cross-cultural literature, we propose that having decision-making control over resources
increases levels of power motivation among Americans but not Chinese, whereas status-elevation increases power motivation
among both Americans and Chinese. These hypotheses were tested experimentally with resource-control, status-elevation, and
neutral conditions. The first hypothesis was fully supported, but the second one was only partially supported. Levels of power
motivation in the neutral condition (i.e., dispositional power motives) were similar for American and Chinese participants,
but power motivation arousal was greater for Americans than Chinese, in both power arousal conditions. These findings contribute
to our understanding of the power motivation construct in a non-Western context. 相似文献

Inhibitory control is widely hypothesized to be the cornerstone of executive function in childhood and the central deficit in a number of developmental disorders, including attention‐deficit/hyperactivity disorder (ADHD). However, recent evidence from adults indicates that performance on response inhibition tasks may primarily reflect non‐inhibitory attentional control (context monitoring) processes. Yet it may be that inhibition plays a more central role in childhood – a time when the architecture of cognitive processes might be more transparent due to wide variability in skill level. Here we directly test inhibitory and context monitoring explanations of task performance on a Go/No‐Go task in a large group of children 4–12 years of age. We conclude that traditional inhibitory conceptualizations of task performance on the Go/No‐Go task cannot account for our findings, calling into question evidence supporting a central role for inhibitory control in cognitive development or developmental psychopathology. 相似文献

The primary aim of this study was to examine the impact of an inhibition manipulation on the effect of age on theory of mind (ToM) in an ecologically valid, affective ToM task. Participants were 30 young and 30 old adults. The Cambridge Mindreading Face-Voice Battery was used to measure ToM; in addition, measures of fluid and crystallized intelligence were taken. Participants were subjected to three levels of inhibitory demand during ToM reasoning: emotional inhibition, non-emotional inhibition, and no inhibition. Old adults performed worse than young adults. The emotional and non-emotional inhibition conditions resulted in worse ToM performance compared to the no inhibition condition. There were no differences in the impact of the inhibition conditions on old and young adults. Regression analyses suggested that old adults’ crystallized intelligence was a significant predictor of ToM performance, whereas it did not predict young adults’ ToM performance. Results are discussed in terms of verbal ability as a possible compensatory mechanism in coping with verbal inhibitory load in ToM reasoning. 相似文献
