The effect of changing the frequency components of an echo relative to the sound source was examined in a two-choice discrimination task. Subjects sat in an anechoic chamber and discriminated the direction of the lag noise burst within a lead-lag pair presented over loudspeakers. The leading noise burst was broadband, and the lagging burst was either high- or low-pass filtered. On some conditions, this test burst pair was preceded by a conditioning train of burst pairs, which also had a broadband lead and either a high- or low-frequency lag. When the frequency content of the echo was held constant across the conditioning train and test burst pair, echo suppression that was built up during the repeating train was maintained for the test burst pair, shown by the subjects’ poor performance in detecting the location of the lagging burst. By comparison, subjects had little difficulty in localizing the lagging burst when the frequency content of the echo changed between the conditioning train and the test burst, indicating that any buildup of suppression during the train was broken when the lagging burst’s spectrum shifted. The data are consistent with an interpretation in which echo suppression is temporarily broken when listeners’ built-up expectations about room acoustics are violated.  相似文献

Heart rate conditioning in the newborn infant   总被引:3,自引:0,他引:3  
In an attempt to condition heart rate in newborns, 21 infants were assigned to Conditioning, Random Control, and Backward Conditioning Groups. During training trials, the Conditioning Group received an eight-second tone (CS), a six-second ISI, and a ten-second presentation of glucose via nipple (UCS) that overlapped the last two seconds of tone. The Random Control Group received tones at the same intertrial intervals as the Conditioning Group, but glucose varied randomly. The Backward Conditioning Group received glucose during the ten seconds immediately preceding tone onset. The response to both CS and UCS during base trials was HR acceleration. The response to tone habituated in all groups, but the acceleration to glucose was maintained throughout conditioning. Although no conditioned response to the tone developed over trials, a large HR deceleration appeared during extinction to the absence of the UCS in the Conditioning Group only. This deceleration was interpreted as an orienting response to the absence of an expected event.  相似文献

The interpersonal dysfunction that characterizes borderline personality disorder (BPD) has generally been studied using broad global measures, leading to a lack of precision. We report on a novel methodology using social network analysis (SNA) to quantify interactions with others in the patient's social world. We assessed the social networks of 22 clinical patients, diagnosed with either BPD (N = 11) or no personality disorder (No PD; N = 11). The social networks of patients with BPD contained a greater number of former romantic partners, and a greater number of relationships that had been terminated. Mixed model analyses found that the No PD group reported higher levels of positive relationships (e.g., trust, social support) with more central members of their social networks, whereas the BPD group did not discriminate among members of their networks. Results suggest deficits in social cognition for positive relations, but not for negative relations such as interpersonal conflict.  相似文献

This investigation tested whether social norms and endorsement of humanitarian values interact to influence authoritarians' attitudes toward immigrants. Oyamot, Borgida, and Fisher (2006) found correlational evidence for a model in which: (1) clear social norms for attitudes toward an outgroup (favorable or unfavorable) influence the authoritarianism–attitude relationship in the direction of the norm, and (2) in the absence of clear social norms, endorsement of humanitarian–egalitarian values attenuate the intolerant tendencies of authoritarians. The current investigation tested the model in a survey experiment conducted in a diverse adult sample (N = 388). We measured participants' levels of authoritarian predisposition and endorsement of humanitarian values. Participants were then randomly told that Americans in general had either negative, positive, or mixed opinions about immigrants and immigration (social norm condition), and then asked about their attitude toward immigrants. Consistent with the model, authoritarianism was negatively related to attitudes toward immigrants in the negative norm condition. However, authoritarians' tendency toward intolerance was attenuated when they thought that Americans in general had positive opinions about immigrants. Also as predicted, when societal norms were depicted as mixed, authoritarians' attitudes depended upon endorsement of humanitarian values: humanitarian authoritarians held positive attitudes and non-humanitarian authoritarians held the most negative attitudes toward immigrants. Implications for understanding the effects of authoritarian predispositions in varying social contexts are discussed.  相似文献

Using Jungian and queer theory, this article examines the queer personas of Ennis and Jack, whose queer archetypes fit into a context that had not generally been thought to contain those archetypes. For perhaps the first time a major motion picture appealed to and depicted what Steven Drukman calls the “gay gaze.” Ennis and Jack conform to socially constructed gender roles (as “masculine,” married men), but they are essentially gay. The queer archetype they fit is that of likes: the double of Plato's Symposium, yet both are bereft of gay icons and supportive archetypal stories. Before Brokeback Mountain, never had a mainstream motion picture with such wide appeal directed gay men's attention to the frank love, and lovemaking, of two such nonstereotypically gay and attractive young men. When they first look each other over outside Joe Aguirre's office, Ennis and Jack are unknowingly objects of each other's gay gaze. As gazers, gay men can appreciate these two young men for who they are, not for whom we'd like them to be, as is the case in other mainstream movies. For once we and our sympathetic heterosexual sisters are bearers of the look. To gaze at images that reflect our “inner selves” is a powerful and profound experience, all the more so for its rarity among gay male viewers.  相似文献

In English, new information typically appears late in the sentence, as does primary accent. Because of this tendency, perceivers might expect the final constituent or constituents of a sentence to contain informational focus. This expectation should in turn affect how they comprehend focus-sensitive constructions such as ellipsis sentences. Results from four experiments on sluicing sentences (e.g., The mobster implicated the thug, but we can't find out who else) suggest that perceivers do prefer to place focus late in the sentence, though that preference can be mitigated by prosodic information (pitch accents, Experiment 2) or syntactic information (clefted sentences, Experiment 3) indicating that focus is located elsewhere. Furthermore, it is not necessarily the direct object, but the informationally focused constituent that is the preferred antecedent (Experiment 4). Expectations regarding the information structure of a sentence, which are only partly cancellable by means of overt focus markers, may explain persistent biases in ellipsis resolution.  相似文献

This study was undertaken in an effort to sharpen selection procedures and improve faculty response to the learning needs of students. Eschewing a traditional anticipatory approach in determining suitability for training, the authors undertook a retrospective study to investigate the learning trajectories of candidates. A learning trajectory is defined as the particular way individuals learn, or fail to learn, as they advance through an Institute's training program. The database of this study grew out of the authors' experience with students in classrooms, in supervision, and from discussions about them in Progression, Selection, and The Evaluation of Learning committees. Realizing the reductionism of categorizing a highly complex and diverse group of individuals, the authors, nonetheless, found that candidates tended to group into five rather distinct categories. This paper discusses in detail the characteristics of these five categories and suggests ways in which this grouping may help in both selection and in planning more effective training for candidates. The authors are fully aware that this study has impressionistic qualities and warrants more rigorous research methods, but hope that it will arouse interest in other psychoanalytic centers and stimulate studies to corroborate, refine, or reject the conclusions reached by this group.  相似文献

In the United States, acceptance of sexual minorities (e.g., gay men and lesbians) has increased substantially since the early 1990s. This study examined whether authoritarians' attitudes have been influenced by the societal shift toward greater acceptance of sexual minorities. Using data from the American National Election Studies (ANES) collected between 1992 and 2012, we tested a model in which authoritarianism, endorsement of egalitarian values, and social norms shifting in the direction of tolerance predict individual attitudes toward sexual minorities and LGBT rights issues. Results indicated that (1) there was a subset of authoritarians who endorsed egalitarian values, (2) authoritarians in general became more tolerant (i.e., held less negative attitudes) toward sexual minorities between 1992 and 2012, and (3) “egalitarian authoritarians” held more positive attitudes toward sexual minorities than other authoritarians. The findings contribute to contemporary theory and research on authoritarianism, which is moving from a monolithic view of authoritarianism to one in which culture and core values activate and shape manifestations of authoritarian tendencies.  相似文献

In this brief rejoinder, we respond to Farmer, Monaghan, Misyak, and Christiansen (2011). We argue that the data still do not support the claim that reading time is affected by the phonological typicality of a word for its part of speech. We also question Farmer et al.'s claim that interleaving syntactic structures in an experiment modifies grammatically based syntactic expectations.  相似文献
