Developments in long-term explicit memory late in the first year of life: behavioral and electrophysiological indices 总被引:4,自引:0,他引:4
Coincident with developments in the temporal-cortical explicit memory network, long-term recall abilities are newly emergent late in the first year of human life. We recorded event-related potentials (ERPs) in 9-month-olds as an index of the integrity of the neural substrate underlying a task thought to reflect explicit memory, namely, deferred imitation. ERP measures of recognition memory 1 week after unique laboratory experiences predicted whether and how much infants recalled of the experiences 1 month later. The findings further imply that memory storage and consolidation processes are a major source of variability in long-term recall memory late in the first year of life. 相似文献

This study explored relations between willingness to disclose in 5 psychotherapy scenarios and 2 independent variables (privilege condition and previous therapy experience). Scenarios involved suicidal, gravely disabled, physically abusive, and sexually abusive patients, and a police officer patient who shot a suspect. For each of the 5 scenarios, participants in the privilege condition had significantly higher willingness-to-disclose scores than participants in the non-privilege condition. There were no significant differences between willingness-to-disclose scores of participants with and without therapy experience; neither was there a significant interaction between privilege condition and therapy experience. Privilege condition was more predictive of willingness to disclose than personal characteristics or therapy experience. Results provide empirical support for the U.S. Supreme Court's recognition of the psychotherapist-patient privilege in Jaffee v. Redmond (1996). 相似文献

This study is one in a series investigating the relationship between impulsive behavior on a Continuous Performance Test (i.e., the Immediate and Delayed Memory Task) and other cognitive deficits measured by clinical instruments. Forty-two adolescents were selected for two groups, controls and hospitalized patients with disruptive behavior disorders. Each adolescent completed the Immediate and Delayed Memory Task and the Benton Visual Retention Test. Our main findings were that, even when controlling for IQ, the Immediate and Delayed Memory Task commission errors were associated with adverse Benton performance, but only in the patient group. These results may be explained by a shared association between processes of impulsivity and other deficits of executive control that may interfere with successful performance of the Benton. 相似文献

Pigeons classified a display of illuminated pixels on a touchscreen as sparse or dense. Correct responses were reinforced with six food pellets; incorrect responses were unreinforced. On some trials an uncertain response option was available. Pecking it was always reinforced with an intermediate number of pellets. Like monkeys and people in related experiments, the birds chose the uncertain response most often when the stimulus presented was difficult to classify correctly, but in other respects their behavior was not functionally similar to human behavior based on conscious uncertainty or to the behavior of monkeys in comparable experiments. Our data were well described by a signal detection model that assumed that the birds were maximizing perceived reward in a consistent way across all the experimental conditions. 相似文献

Currently there are disputes in the infancy literature concerning when infants are first able to individuate physical objects by their features or properties. This issue has taken on new significance following claims that individuation by feature is linked to the emergence of object kind concepts toward the end of the first year. Needham (2001, this issue) presents evidence that infants as young as 4.5 months old can individuate objects by feature. We locate this controversy within the framework of brain mechanisms that index or track individual objects, drawing upon theories of attention and working memory developed in the study of adults. We find that Needham's work contributes to two issues: categorization and the effect of object history on the individuation of objects in a complex display. 相似文献

Three volunteers watched a previously recorded video of one of them singing, as cheek sensors monitored their blushing. When performers watched videotapes of their performance, they blushed significantly more than strangers, but not more than their own friends, watching with them. Friends and strangers did not differ significantly in blushing, however. Skin conductance arousal responses of performers and friends, but not performers and strangers, or friends of performers and strangers, were correlated. In a second experiment, strangers who sang before watching another person sing blushed more than strangers who did not sing first, or who sang and then watched a neutral video. This suggests that performing the embarrassing act may have predisposed people to blush, perhaps empathically, later. No gender differences were seen in blushing. Embarrassability questionnaire scores did not correlate with blushing. Empathic accuracy, and associative learning, are proposed to account for the results. 相似文献

Three experiments examined infants' and adults' perception of causal sequences of events. In a causal-chain sequence, the first action causes a second action that then causes a final outcome; in a temporal-chain sequence, the first two actions are independent and the second action causes a final outcome. Infants and adults were shown the same event sequences; infants were tested using a visual habituation paradigm, whereas adults were given a questionnaire. Experiment 1 indicated that 15-month-old infants perceive the primary cause of the final outcome to be the first action in a causal chain but the second action in a temporal chain. Experiment 2 showed that adults interpret the causal sequences in a manner similar to that of 15-month-olds. Finally, Experiment 3 showed that 10-month-old infants do not yet perceive causal sequences in the same manner as 15-month-olds and adults. These results are interpreted in terms of both infants' developing knowledge of causal events and adults' attributions of causality in complex events. 相似文献

A sample of 172 male clergy within the Church of England completed the Eysenck Personality Questionnaire together with an index of charismatic experience. The data demonstrate that charismatic experience is positively associated with extroversion, but related to neither neuroticism nor psychoticism. 相似文献

In a series of experiments on immediate probed recognition for eight 3-digit numbers, it was shown that if the target modality involved auditory components and the effect of the similarity of the modality of the probe to that of the targets was controlled, unequivocal evidence was obtained for an auditory superiority effect (modality effect) for hit rates for the final items of the list. Moreover, false-alarm rates were significantly lower following targets with an auditory component than they were following silently seen targets. It is argued that this pattern of hits and false alarms is consistent with the idea that targets that have an auditory component yield memory representations that are better grouped as units than are those for targets that are only silently seen; in particular, if a new probe has a first digit that accidentally matches the first digit of a target item, it is more likely that the subject will mistakenly identify this new probe as old (give a false alarm) if the target has only been partially encoded because it was only silently seen. 相似文献
