Repetition blindness (RB) was investigated in 6 experiments. In the first 3 experiments participants detected vowel targets in 11-letter sequences. When all letters were uppercase, detection was poorer for same (e.g., AA) than for different (e.g., AO) targets. However, when one target was uppercase and the other lowercase, RB was found only for targets visually identical except for size (e.g., Oo), not for visually different pairs (e.g., Aa). Experiment 4 found RB for visually identical versus different consonant-vowel-consonant words. Experiments 5 and 6 replicated Kanwisher's (1987) experiment in which RB was insensitive to word case but revealed these effects to be artifacts of poor recognition of 5-letter words coupled with a biased guessing strategy. Overall, these experiments found RB only at a low level of visual information processing. 相似文献

The current study explores the relations between individualism, motivation, and feedback‐seeking behaviors. Specifically, we examined how three motivational factors (i.e., status‐striving, achievement‐striving, and affiliation‐striving) mediated or moderated the relations between individualism and feedback‐seeking behaviors. Data were collected from 154 Singaporean undergraduate students across two time periods. Results indicated that only status motivation mediates the individualism–feedback‐seeking relation. Affiliation was found to moderate that same relation but only for a specific subset of feedback‐seeking behaviors. The implications of these findings for performance management and development are discussed. 相似文献

Pregnant primiparous rats were subjected to four days of light restraint stress on postconception days 7 through 10, inclusive, coincident with the development of the fetal gastrointestinal system. Twenty male and twenty female offspring from prenatally stressed and nonstressed rats were then subjected to two hours of supine cold-restraint as adults. Eighty percent of nonprenatally stressed offspring developed gastric lesions, while 47.5% of offspring of prenatally stressed mothers displayed lesions. A significant sex-stress interaction was detected, indicating that male offspring from prenatally stressed mothers display less severe gastric lesions in response to restraint stress as adults than do male offspring from nonprenatally stressed mothers. Female offspring from both prenatal stress conditions showed similar levels of stress-induced lesions. 相似文献

The anatomy of loneliness 总被引:4,自引:0,他引:4
John T. Cacioppo Louise C. Hawkley Gary G. Berntson 《Current directions in psychological science》2003,12(3):71-74
Loneliness is a potent but little understood risk factor for broad-based morbidity and mortality. We review five social neurobehavioral mechanisms that may account for this association. The evidence suggests that different mechanisms explain short-term and long-term effects, and that the long-term effects operate through multiple pathways. Implications for the design of interventions are discussed. 相似文献

Ss classified as quickly as possible stimuli back-projected one at a time on a small screen by pressing one of two levers in response to each stimulus, according to the levels of a single specified binary stimulus dimension. Stimuli were rectangles varying in height alone, in width alone, or in both dimensions, in either a correlated or an orthogonal fashion. Stimuli followed responses by a fixed interval of 82, 580, or 1,080 msec. Response time was longer when both dimensions varied orthogonally than when only one dimension varied, indicating that Ss were unable to avoid perceiving the rectangle figures as wholes. Repeated stimuli were responded to more quickly than stimuli which were different from the immediately preceding stimulus in all conditions. With orthogonally combined dimensions, response time to stimulus repetitions was lowest, increased when the stimulus changed while the response was repeated, and increased still further when both the stimulus and the response changed. Increasing the time interval between stimuli decreased response time for nonrepetitions, while response time for repetitions was relatively unaffected. The results were discussed in terms of two models of serial choice reaction time. 相似文献

The purpose of the present study was to investigate the degree to which foveal information is necessary for object identification. To explore this question, we used an artificial moving scotoma paradigm to eliminate a region of a currently viewed display in real time as a function of eye position. Subjects examined linear arrays of four line drawings of objects while their eye movements were recorded. Immediately following each array, a test probe was presented to test the degree to which the subject had identified those objects. Three conditions were compared, one in which a central foveal scotoma was created, one in which an extrafoveal scotoma was created, and a control condition in which the scotoma was absent. The main result was that identification accuracy was very good, but eye-movement behavior was disrupted when a foveal scotoma was present. These results suggest that foveal information is not necessary but is beneficial for perceptual encoding during object identification; the loss of foveal information can be overcome as long as compensatory extrafoveal processing is possible. 相似文献

'Diversity', the theme of our conference, carries a subversive sub-text in totalitarian societies. This is one of the themes presented as the current revival of psychoanalysis in the more democratic post-Communist Russia is explored. The history of psychoanalysis in Russia is summarized with a focus on its politicization, which led to initial interest in its theory (by way of a misapprehension of its tenets), and then to ultimate suppression of psychoanalytic thinking as an ideology deemed antagonistic to the totalitarian regime. In contrast, features of psychoanalysis and democracy are explored for their mutual affinities. The background of the resourceful new generation of analytic therapists is discussed, especially in regard to their experience of the parallel meanings of the word 'repression' (political, psychological). There is a persistence of some traits in patients and practitioners alike that are referable to past repression, such as the newness of verbal treatments, the inhibition of psychological curiosity, the ambivalent lure of certainty, and the pressure of authoritarian introjects. It is noted that psychoanalysis has its own history of a posture opposed to pluralism and diversity, which deepens the dialogue on the mutual engagement between psychoanalysis and the vicissitudes of its history in Russian culture. 相似文献

Acculturation,stress, and depressive symptoms among Korean immigrants in the United States 总被引:2,自引:0,他引:2
A sample of 157 Korean immigrants responded to measures of acculturation level, stress from acculturation, and depressive symptoms. The authors hypothesized that adaptive acculturation would depend on assimilation regarding social interactions and the host culture's language as well as on retention of a core identity, including values and traditions of the culture of origin. Consistent with the mediation hypothesis, acculturation, based on a factor representing language use and social relationships, was related to lower acculturative stress and, in turn, lower depression. However, there was no direct support for the integrative, or bicultural, strategy of acculturation. Stress did not mediate the effect of a 2nd acculturation factor, identity and tradition-based acculturation. Rather, this measure of acculturation was directly related to higher depression (i.e., immigrants reporting abandonment of Korean identity, traditions, and values scored higher for depression). 相似文献
