The approximately 20-msec perceptual threshold for identifying order of onset for components of auditory stimuli has been considered both as a possible factor contributing to the perception of voicing contrasts in speech and as no more than a methodological artifact. In the present research, we investigate the identification of the temporal order of onset of spectral components in terms of the first of a sequence of thresholds for complex stimuli (modeled after consonant-vowel [CV] syllables) that vary in degree of onset. The results provide clear evidence that the difference limen (DL) for discriminating differences in onset time follows predictions based on a fixed perceptual threshold or limit at relatively short onset differences. Furthermore, the DL seems to be a function of context coding of stimulus information, with both the DL and absolute threshold probably reflecting limits on the effective perception and coding of the short-term stimulus spectrum. 相似文献

Recently, Andersen and Cyranowski (1994) presented a self-report measure of women's sexual self-schema, or cognitive view of the self regarding sexuality. In the current study, we investigated potential relationships between women's sexual self-schema and physical attractiveness, body size and shape, and body image. Young adult women ( N = 199) completed questionnaires and were weighed, measured, and rated for facial attractiveness. Results revealed that sexual self-schema was unrelated to body size or shape, general body dissatisfaction, history of teasing about weight, and degree of investment in personal appearance. Sexual self-schema scores significantly correlated with experimenter-rated facial attractiveness, self-rated facial and bodily attractiveness, and degree of social avoidance due to concerns over personal appearance, however. In a multiple regression analysis, only self-rated facial attractiveness and social avoidance were unique predictors. Results are discussed with regard to implications for the development of women's sexual self-schema and directions for future research. 相似文献

In nearly all reported orienting task studies, the question is asked before the item or items are presented. This paper reports two experiments wherein the question was asked after the item was presented. These experiments found that an orthographic orienting task did not produce poorer retention than a semantic orienting task when (1) the orthographic task was presented in such a way to ensure that the list items would be encoded as units and (2) the test was designed to eliminate the effect of encoding elaboration to positive-response orienting questions. It was concluded that the depth-of-processing effect was composed of two components. One of these is a task-demand component that affects the probability of encoding target items as identifiable units. The second component of processing depth is trace elaboration to positive-response questions. In most experiments, the two components combine to produce better memory performance for targets presented with semantic orienting questions. However, the two components can be examined independently of each other to determine the degree to which each contributes to a particular experimental effect. 相似文献

M. J. Lavin, B. Freise, and S. Coombes (Behavioral and Neural Biology, 1980, 28, 15–33) have shown that if two rats consume a flavored solution and one is poisoned, the unpoisoned partner will also exhibit a flavor aversion during a later preference test. Experiments 1 and 2 showed that a sufficient condition for obtaining this aversion is that the poisoned partner be present with the unpoisoned rat after it has consumed the flavored solution. It is not necessary that the poisoned partner be present when the flavored solution is consumed or indeed have had any exposure to the flavored solution. Experiment 3 showed that the unpoisoned partner can exhibit a flavor aversion when there is a temporal gap of as long as 6 hr between consumption of the flavored solution and exposure to the poisoned rat. 相似文献

Classical conditioning of the rabbit nictitating membrane (NM) response was adapted as a model system for simultaneous measurement of behavioral and neural responses in auditory signal detection. Animals were trained to a 36-dB spectral-level white-noise CS paired with a corneal airpuff US. The CS intensity was then reduced to threshold, using a modified staircase procedure, and responses on detect and nondetect trials were compared for the same stimulus intensities. At threshold, the behavioral NM response was dichotomous, being present on detect trials and completely absent on nondetect trials. In marked contrast, evoked neural unit activity to the CS recorded from the anteroventral cochlear nucleus was clearly present and identical on both detect and nondetect trials, suggesting that the detection “decision” is made more centrally than the cochlear nucleus. 相似文献

Direct Perception is the view that we can see others' mental states, i.e. that we perceive others' mental states with the same immediacy and directness that we perceive ordinary objects in the world. I evaluate Direct Perception by considering whether we can see intentions, a particularly promising candidate for Direct Perception. I argue that the view equivocates on the notion of intention. Disambiguating the Direct Perception claim reveals a troubling dilemma for the view: either it is banal or highly implausible. 相似文献

To promote trauma-informed professional supports and services to maltreated youth, it is imperative that researchers explore foster parents’ knowledge of child trauma. However, there is a dearth in the literature related to this topic. This exploratory study utilizes a convenience sample (N = 219) of foster parents in one southeastern state. Variables of interest include actual and perceived knowledge about child trauma. After a terse review of background literature, this paper will explicate key results, discuss these findings, and identify salient practice and policy implications derived from this study. The paper will conclude by delineating apposite areas for future research. 相似文献

Chronic pain impacts individuals with pain as well as their loved ones. Yet, there has been little attention to the social context in individual psychological treatment approaches to chronic pain management. With this need in mind, we developed a couple-based treatment, “Mindful Living and Relating,” aimed at alleviating pain and suffering by promoting couples’ psychological and relational flexibility skills. Currently, there is no integrative treatment that fully harnesses the power of the couple, treating both the individual with chronic pain and the spouse as two individuals who are each in need of developing greater psychological and relational flexibility to improve their own and their partners’ health. Mindfulness, acceptance, and values-based action exercises were used to promote psychological flexibility. The intervention also targets relational flexibility, which we define as the ability to interact with one’s partner, fully attending to the present moment, and responding empathically in a way that serves one’s own and one’s partner’s values. To this end, the intervention also included exercises aimed at applying psychological flexibility skills to social interactions as well as emotional disclosure and empathic responding exercises to enhance relational flexibility. The case presented demonstrates that healthy coping with pain and stress may be most successful and sustainable when one is involved in a supportive relationship with someone who also practices psychological flexibility skills and when both partners use relational flexibility skills during their interactions. 相似文献
