Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N = 106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months. 相似文献

Speech perception (SP) most commonly refers to the perceptual mapping from the highly variable acoustic speech signal to a linguistic representation, whether it be phonemes, diphones, syllables, or words. This is an example of categorization, in that potentially discriminable speech sounds are assigned to functionally equivalent classes. In this tutorial, we present some of the main challenges to our understanding of the categorization of speech sounds and the conceptualization of SP that has resulted from these challenges. We focus here on issues and experiments that define open research questions relevant to phoneme categorization, arguing that SP is best understood as perceptual categorization, a position that places SP in direct contact with research from other areas of perception and cognition. 相似文献

Ward A Mann T Westling EH David Creswell J Ebert JP Wallaert M 《Aggressive behavior》2008,34(6):584-592
The attentional myopia model of behavioral control [Mann and Ward, 2007] was tested in an experiment investigating the relationship between physiological arousal and aggression. Drawing on previous work linking arousal and narrowed attentional focus, the model predicts that arousal will lead to behavior that is relatively disinhibited in situations in which promoting pressures to aggress are highly salient. In situations in which inhibitory pressures are more salient, the model predicts behavior that is relatively restrained. In the experiment, 81 male undergraduates delivered noise-blasts against a provoking confederate while experiencing either high or low levels of physiological arousal and, at the same time, being exposed to cues that served either to promote or inhibit aggression. In addition to supporting the predictions of the model, this experiment provided some of the first evidence for enhanced control of aggression under conditions of heightened physiological arousal. Implications for interventions designed to reduce aggression are discussed. 相似文献

Two experiments investigated infants' ability to localize tactile sensations in peripersonal space. Infants aged 10 months (Experiment 1) and 6.5 months (Experiment 2) were presented with vibrotactile stimuli unpredictably to either hand while they adopted either a crossed- or uncrossed-hands posture. At 6.5 months, infants' responses were predominantly manual, whereas at 10 months, visual orienting behavior was more evident. Analyses of the direction of the responses indicated that (a) both age groups were able to locate tactile stimuli, (b) the ability to remap visual and manual responses to tactile stimuli across postural changes develops between 6.5 and 10 months of age, and (c) the 6.5-month-olds were biased to respond manually in the direction appropriate to the more familiar uncrossed-hands posture across both postures. The authors argue that there is an early visual influence on tactile spatial perception and suggest that the ability to remap visual and manual directional responses across changes in posture develops between 6.5 and 10 months, most likely because of the experience of crossing the midline gained during this period. 相似文献

This article assesses Alexander L. George's seminal contributions in six areas of political psychology and qualitative case study methods. These include George's work on psychological inputs in political processes, the intersection of history and political science, methods of within-case analysis such as process tracing, the use of structured, focused case comparisons (SFCC), the development of typological theories, and the connections among theory, empirical research, teaching, and policy. The article concludes with an analysis of four ongoing dimensions of George's research agenda: the need to integrate theories on purposive, cognitive, social, and motivational dynamics of decision making; the importance of methodological safeguards against our own cognitive biases as researchers; ways of integrating qualitative, quantitative, formal, and experimental research methods; and ways of modeling and testing theories on causal complexity. 相似文献

The effect of advance ('precue') information on short aiming movements was explored in adults, high school children, and primary school children with and without developmental coordination disorder (n=10, 14, 16, 10, respectively). Reaction times in the DCD group were longer than in the other groups and were more influenced by the extent to which the precue constrained the possible action space. In contrast, reaction time did not alter as a function of precue condition in adults. Children with DCD showed greater inaccuracy of response (despite the increased RT). We suggest that the different precue effects reflect differences in the relative benefits of priming an action prior to definitive information about the movement goal. The benefits are an interacting function of the task and the skill level of the individual. Our experiment shows that children with DCD gain a benefit from advance preparation in simple aiming movements, highlighting their low skill levels. This result suggests that goal-directed RTs may have diagnostic potential within the clinic. 相似文献

Those familiar with contemporary continental philosophy know well the defenses Husserlians have offered of Husserl’s theory
of inner time-consciousness against post-modernism’s deconstructive criticisms. As post-modernism gives way to Deleuzean post-structuralism,
Deleuze’s Le bergsonisme has grown into the movement of Bergsonism. This movement, designed to present an alternative to phenomenology, challenges
Husserlian phenomenology by criticizing the most “important… of all phenomenological problems.” Arguing that Husserl’s theory
of time-consciousness detailed a linear succession of iterable instants in which the now internal to consciousness receives
prejudicial favor, Bergsonism concludes that Husserl derived the past from the present and cannot account for the sense of
the past, which differs in kind from the present. Consequently, everything on Husserl’s account remains present and his theory
cannot accommodate for time’s passage. In this paper, I renew the Husserlian defense of Husserl’s theory of time-consciousness
in response to the recent movement of Deleuzean Bergsonism. Section one presents Bergsonism’s notion of the past in general
and its critique of Husserl’s theory of time-consciousness. Section two presents a rejoinder to Bergsonism’s critique of Husserl,
questioning (1) its understanding of the living-present as linearly extended, (2) its conflation of the living-present with
Husserl’s early schema-apprehension interpretation, and (3) its failure to grasp Husserl’s revised understanding of primary
memory as a result of (2). In conclusion, I suggest that Husserl’s theory of retention might articulate a notion of the past
more consistent with Bergson than Bergsonism itself.

Patients with mild Alzheimer's disease (AD) display a greater tendency to endorse unstudied items as "old" on memory tests than healthy older adults. This liberal response bias may result in mistaken beliefs about the completion of common tasks. This research attempted to determine whether it was possible to shift the response bias of mild AD patients to be more conservative on a recognition memory test through behavioral intervention. Patients with mild AD and matched controls were evaluated with two almost identical paradigms, separated by about one week. For each session, 30 words were studied and 60 words (half studied, half novel) were shown at test. During one session participants were told that 30% of words were old, and at the other session that 70% were old. We found that both groups were able to shift their response bias between the two conditions. That patients with mild AD were able to successfully shift their response bias demonstrates that--despite their overall liberal response bias and poor memory relative to controls--one component of metamemorial ability is preserved in patients with mild AD. 相似文献

The influence that philosophy of science has had on scientific practice is as controversial as it is undeniable, especially in the case of biology. The dynamic between philosophy and biology as disciplines has developed along two different lines that can be characterized as ‘paternal’, on the one hand, and more ‘fraternal’, on the other. The role Popperian principles of demarcation and falsifiability have played in both the systematics community as well as the ongoing evolution–creation debates illustrate these contrasting forms of interdisciplinary engagement, underscoring the influence philosophy of science in shaping our contemporary understanding of biology in the North American context. However, a strict disciplinary distinction between philosophy and science may itself be a false dichotomy that risks hampering future development of the biological sciences. By actively engaging with philosophical considerations as an integral part of their scientific practice, nineteenth‐century biologists offer an interesting counterpoint to current trends of overspecialization and provide a model of scientists who avoided extremes of antagonism with, or subservience to, philosophy. 相似文献

OBJECTIVE: To assess the effects of a communication skills training program for physicians and patients. DESIGN: A randomized experiment to improve physician communication skills was assessed 1 and 6 months after a training intervention; patient training to be active participants was assessed after 1 month. Across three primary medical care settings, 156 physicians treating 2,196 patients were randomly assigned to control group or one of three conditions (physician, patient, or both trained). MAIN OUTCOME MEASURES: Patient satisfaction and perceptions of choice, decision-making, information, and lifestyle counseling; physicians' satisfaction and stress; and global ratings of the communication process. RESULTS: The following significant (p < .05) effects emerged: physician training improved patients' satisfaction with information and overall care; increased willingness to recommend the physician; increased physicians' counseling (as reported by patients) about weight loss, exercise, and quitting smoking and alcohol; increased physician satisfaction with physical exam detail; increased independent ratings of physicians' sensitive, connected communication with their patients, and decreased physician satisfaction with interpersonal aspects of professional life. Patient training improved physicians' satisfaction with data collection; if only physician or patient was trained, physician stress increased and physician satisfaction decreased. CONCLUSION: Implications for improving physician-patient relationship outcomes through communication skills training are discussed. 相似文献
