Rats (rattus norvegicus) anticipated the arrival of a food pellet unconditioned stimulus (US) even when the conditioned stimulus (CS) signaled no overall change or a substantial decrease in the overall rate of US occurrence. Pellet USs were scheduled probabilistically in the intertrial interval at either an equivalent rate (Experiment 1) or a four times higher rate (Experiments 2 and 3) than in the CS, which included one fixed-time target US. Conditioning has been said to involve learning "whether" (contingency) the CS signals a change in the US, and if so, "when" (contiguity) the US is scheduled to arrive. Our results suggest that "when" trumps "whether," challenging the received view that a positive CS-US contingency is necessary for successful conditioning. 相似文献

Limited research has examined the effects of using disclaimers on person perception, and none has examined disclaimer effectiveness. Four studies test whether disclaimers effectively ward off negative judgments regarding the specific disclaimed traits. Study 1 finds that using an arrogance disclaimer ("I don't mean to sound arrogant, but . . .") increased judgments of the speaker's arrogance but only when followed by an arrogant comment. Studies 2 and 3 yield similar findings using laziness and selfishness disclaimers. Studies 2, 3, and 4 examine five possible underlying mechanisms regarding why disclaimers can backfire. The most support was obtained for the notion that disclaimers increase an audience's expectations that the speaker will say something consistent with the unwanted trait, which then increases perceptions of that trait in the speaker. We discuss some possible moderating variables as well as some implications of these findings for general impression formation models. 相似文献

OBJECTIVE: A major problem in the delivery of mental health services is the lack of availability of empirically supported treatment, particularly in rural areas. To date no studies have evaluated the administration of an empirically supported manual-based psychotherapy for a psychiatric condition via telemedicine. The aim of this study was to compare the relative efficacy and acceptability of a manual-based cognitive-behavioral therapy (CBT) for bulimia nervosa (BN) delivered in person to a comparable therapy delivered via telemedicine. METHOD: One hundred twenty-eight adults meeting DSM-IV criteria for BN or eating disorder-not otherwise specified with binge eating or purging at least once per week were recruited through referrals from clinicians and media advertisements in the targeted geographical areas. Participants were randomly assigned to receive 20 sessions of manual-based, CBT for BN over 16 weeks delivered either face-to-face (FTF-CBT) or via telemedicine (TV-CBT) by trained therapists. The primary outcome measures were binge eating and purging frequency as assessed by interview at the end of treatment, and again at 3- and 12-month follow-ups. Secondary outcome measures included other bulimic symptoms and changes in mood. RESULTS: Retention in treatment was comparable for TV-CBT and FTF-CBT. Abstinence rates at end-of-treatment were generally slightly higher for FTF-CBT compared with TV-CBT, but differences were not statistically significant. FTF-CBT patients also experienced significantly greater reductions in eating disordered cognitions and interview-assessed depression. However, the differences overall were few in number and of marginal clinical significance. CONCLUSIONS: CBT for BN delivered via telemedicine was both acceptable to participants and roughly equivalent in outcome to therapy delivered in person. 相似文献

Abstract : This article asserts the value of service learning as integral to youth ministry's future. However, service learning often lacks an appropriate philosophical foundation and an effectual process. Therefore, we offer Luther's doctrine of vocation as a framework for engaging youth in service experiences, which in return becomes a concrete way to experience the doctrine of vocation and, more importantly, the freedom of a Christian. Framed and interpreted through a vocational lens, service experiences aid youth in recognizing the urgency of a life of faith, 相似文献

IS SELF-OBJECTIFICATION RELATED TO INTEROCEPTIVE AWARENESS? AN EXAMINATION OF POTENTIAL MEDIATING PATHWAYS TO DISORDERED EATING ATTITUDES 总被引:1,自引:1,他引:0
Although there has been considerable empirical support for Objectification Theory ( Fredrickson & Roberts, 1997 ), findings have been mixed regarding self-objectification's relationship to interoceptive awareness, an awareness of one's internal physical and emotional states. We examined whether interoceptive awareness mediated the relationship between self-objectification and disordered eating attitudes, exploring more specifically the relative contributions of difficulties recognizing feelings of hunger and satiety versus emotions. College women ( N = 195) completed measures assessing self-objectification, interoceptive awareness, awareness of emotions, and disordered eating attitudes. Self-objectification correlated significantly more strongly with interoceptive awareness when internal cues about hunger and satiety were assessed. The relationship between self-objectification and disordered eating attitudes was partially mediated by interoceptive awareness. Results revealed that interoceptive awareness may best be captured by a measure that includes lack of awareness of both hunger and satiety and emotional states. Research and clinical implications of these findings are discussed. 相似文献

The ability to form associations between choice alternatives and their contingent outcomes is an important aspect of learning that may be sensitive to hippocampal dysfunction in memory disorders of aging such as amnestic mild cognitive impairment (MCIa), or early Alzheimer disease. In this preliminary study we examined brain activation using functional magnetic resonance imaging (fMRI) in 12 healthy elderly participants and nine patients with MCIa during an associative learning task. Using a high-field 3.0-Tesla MRI scanner, we examined the dynamic neural response during associative learning over trials. The slope of signal attenuation associated with learning was analyzed for differences between groups within an a priori defined hippocampal region. Results indicated dynamic signal attenuation associated with learning in the healthy elderly sample, but not in MCIa. The absence of an associative learning effect in the MCIa sample reaffirms an important link between the learning difficulties that are commonly encountered in MCIa and the mesial temporal region. 相似文献

This forum revisits Paulo Freire's Pedagogy of the Oppressed on the 50th anniversary of its publication in 1968. William R. Myers's opening essay reflects on his discovery of the book and the impact it has had on his life as a Christian minister and theological educator. He provides a Freirean critique of his own schooling and of church and society today. He pulls out several themes in Freire's work, demonstrating their usefulness for cultural analysis and critique in a variety of educational contexts. Succeeding essays by Tina Pippin, Neomi De Anda, and Cláudio Carvalhaes describe specific Freirean‐style pedagogies they have used in their classrooms. 相似文献

Mental health systems need scalable solutions that can reduce the efficacy–effectiveness gap and improve mental health outcomes in community mental health service settings. Two major challenges to delivery of high-quality care are providers’ fidelity to evidence-based treatment models and children’s and caregivers’ engagement in the treatment process. We developed a novel, tablet-based application designed to enhance via technology the quality of delivery of trauma-focused cognitive-behavioral therapy (TF-CBT). We piloted its use in four community mental health service organizations using a blocked randomized controlled trial to examine the feasibility of implementing tablet-facilitated TF-CBT versus standard TF-CBT with 13 providers and 27 families. Provider fidelity and child engagement in treatment were observationally measured via session audio recording. Parent and child perceptions of the tablet application were assessed using structured interviews and mixed-method analyses. Providers actively and appropriately used tablet TF-CBT to facilitate treatment activities. Providers and families expressed high satisfaction with its use, demonstrating acceptability of this approach. Youth and caregivers in both conditions reported high alliance with their providers. Overall, we found that tablet-facilitated treatment is accepted by providers and families and may be integrated into mental health treatment with minimal training. Further study is needed to examine the extent to which technology-based applications may enhance the reach, quality, and clinical outcomes of mental health treatment delivered to children and families. 相似文献

This investigation examined gender differences in niche-building preference and activity among 238 8th and 9th grade boys and girls. A questionnaire was developed to measure both the actual and preferred bedroom content, bedroom design activity, and the level of perceived influence by the immediate and extended family, friends, and social institutions. Gender differences were identified for preference, activity, and influence in bedroom design and decoration. Girls and boys differed in the type of items contained in their bedrooms. Girls' rooms contained stuffed animals and pictures of people, including themselves, more frequently than the boys' rooms. In contrast, boys' rooms contained sports-related items, and things for building or that they had built themselves. Although bedroom design activity for both boys and girls was influenced by older teens, friends, media, and popular culture, boys (but not girls) were also influenced by their mothers, fathers, girlfriends, and activities such as sports, Boy or Girl Scouts, and music lessons. 相似文献

Administration of psychological questionnaires via the Internet has gained popularity in recent years and touts many advantages. However, before questionnaires that were originally developed as paper-and-pencil measures can be confidently administered over the Internet, it is necessary to document the equivalence of the paper and computer-generated versions [American Psychological Association. (1986). Guidelines for computer-based tests and interpretations. Washington, DC: American Psychological Association; Cohen, R.J., Swerdlik, M.E., & Smith, D.K. (1992). Psychological testing and assessment (2nd ed.). Mountain View, CA: Mayfield Publishing; Cronbach, L.J. (1990). Essentials in psychological testing (5th ed.). New York: Harper Collins; Meier, S. (1994). The chronic crisis in psychological measurement and assessment: A historical survey. San Diego: Academic Press; Schulenberg, S.E., & Yutrzenka, B.A. (2001). Equivalence of computerized and conventional versions of the Beck Depression Inventory- II (BDI-II). Current Psychology: Developmental, Learning, Personality, Social, 20, 216-230]. The current study tested this equivalence for the Obsessive Compulsive Inventory [Foa, E.B., Kozak, M.J., Salkovskis, P.M, Coles, M.E., & Amir, N. (1998). The validation of a new obsessive compulsive disorder scale: The obsessive-compulsive inventory. Psychological Assessment, 10(3), 206-214] and the Obsessive Beliefs Questionnaire-44 [Obsessive Compulsive Cognitions Working Group. (2005). Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory-Part 2: Factor analyses and testing of a brief version. Behaviour Research and Therapy, 43, 1527-1543] in an unselected student sample. Study results support the equivalence of these measures of obsessive compulsive disorder (OCD) symptoms and beliefs independent of administration method (paper versus secure project website). These findings create new opportunities for conducting OCD-related research online. 相似文献
