S. C. Gaitan and J. T. Wixted (2000) proposed that when pigeons are trained on a conditional discrimination to associate 1 duration sample with 1 comparison and 2 other duration samples with a 2nd comparison, they detect only the single duration, and on trials involving either of the 2 other duration samples, they respond to the other comparison by default. In 2 experiments, the authors show instead that pigeons lend to treat the retention intervals (such as those used by Gaitan and Wixted) as intertrial intervals, and thus, they tend to treat all trials with a delay as 0-s sample trials. The authors tested this hypothesis by showing that divergent retention functions do not appear when the retention interval is discriminably different from the intertrial interval. 相似文献

This paper describes Skills for Academic and Social Success (SASS), a cognitive–behavioral, school-based intervention for adolescents with social anxiety disorder. Clinic-based treatment studies for socially anxious youth are reviewed, and a strong rationale for transporting empirically-based interventions into schools, such as SASS, is provided. The SASS program consists of 12, 40-min group sessions that emphasize social skills and in-vivo exposure. In addition to group sessions, students are seen individually at least twice and participate in 4 weekend social events with prosocial peers from their high schools. Meetings with teachers provide information about social anxiety and facilitate classroom exposures for socially anxious participants. Parents attend 2 psychoeducational meetings about social anxiety, its treatment, and approaches for managing their childs anxiety. Initial findings regarding the programs effectiveness are presented. We conclude by discussing the challenges involved in implementing treatment protocols in schools and provide suggestions to address these issues. 相似文献

The Wisconsin Personality Disorders Inventory (WISPI-IV; Klein & Benjamin, 1996) is the latest version of a self-report measure of DSM-IV personality disorders (PDs) derived from an interpersonal perspective. When categorical diagnoses derived from the WISPI-IV were compared with independent SCID-II diagnoses, the majority of the kappas were poor (>.40). However, all but one of the effect sizes for the differences in WISPI-IV means between groups with and without SCID-II diagnoses were large (>.80). When SCID-II and WISPI-IV dimensional scores were considered, the average r between profiles was .61 (median = .58) and correlations between corresponding PD scales (mean diagonal r = .48; mean off-diagonal r = .18) indicated good convergent and discriminant validity for five of the WISPI-IV scales. These results add to the cumulating evidence suggesting greater reliability and validity of dimensional over categorical scores for PDs. Researchers and clinicians interested in having an efficient method of assessing PDs may consider using a dimensional approach such as the WISPI-IV as an alternative to diagnostic interview. 相似文献

The Americans with Disabilities Act (ADA), and Sections 504 and 508 of the Rehabilitation Act, prohibit discrimination against people with disabilities in all aspects of daily life, including education, work, and access to places of public accommodations. Increasingly, these antidiscrimination laws are used by persons with disabilities to ensure equal access to e-commerce, and to private and public Internet websites. To help assess the impact of the anti-discrimination mandate for educational communities, this study examined 157 website home pages of Iowa public high schools (52% of high schools in Iowa) in terms of their electronic accessibility for persons with disabilities. We predicted that accessibility problems would limit students and others in obtaining information from the web pages as well as limiting ability to navigate to other web pages. Findings show that although many web pages examined included information in accessible formats, none of the home pages met World Wide Web Consortium (W3C) standards for accessibility. The most frequent accessibility problem was lack of alternative text (ALT tags) for graphics. Technical sophistication built into pages was found to reduce accessibility. Implications are discussed for schools and educational institutions, and for laws, policies, and procedures on website accessibility. 相似文献

The bidirectional control procedure was used to determine whether pigeons (Columba livia) would imitate a demonstrator that pushed a sliding screen for food. One group of observers saw a trained demonstrator push a sliding screen door with its beak (imitation group), whereas 2 other groups watched the screen move independently (possibly learning how the environment works) with a conspecific either present (affordance learning with social facilitation) or absent (affordance learning alone). A 4th group could not see the screen being pushed (sound and odor control). Imitation was evidenced by the finding that pigeons that saw a demonstrator push the screen made a higher proportion of matching screen pushes than observers in 2 appropriate control conditions. Further, observers that watched a screen move without a demonstrator present made a significantly higher proportion of matching screen pushes than would be expected by chance. Thus, these pigeons were capable of affordance learning. 相似文献

This article explores factors important in the study and examination of corporate culture and change. The particular focus is on the technological methods used to conduct a study of accessible technology and corporate culture at Microsoft Corporation. Reasons for particular approaches are explained. Advantages and challenges of emerging technologies that store and retrieve information in the study of corporate culture are reviewed. 相似文献

"The force that through the green fuse drives the flower drives my green age..."--Dylan Thomas (1952). The beautiful evocative words of Dylan Thomas speak to the driving life force that pulses through all creation. So what, then, drives our organization, the American Group Psychotherapy Association (AGPA)? What underlying stream can we tap into to provide the energy, power, and vitality we need to go on being in a meaningful and productive fashion? And, what internal compass can we rely on to steer us in the right direction, to guide us in how we function as an organization? My purpose here is to consider how we formulate our objectives, determine our priorities, make decisions, and insure, as best we can, that we are pursuing that which is meaningful and essential, not veering drastically off course. To do this, I would like to focus briefly on the current organizational structure of AGPA, then examine the use of a strategic planning process, review our accomplishments, and lastly explore hopes and dreams for our future as the premier group psychotherapy organization in the United States. 相似文献

Social anxiety disorder, whose onset peaks in adolescence, is associated with significant impairment. Despite the availability
of effective treatments, few affected youth receive services. Transporting interventions into schools may circumvent barriers
to treatment. The efficacy of a school-based intervention for social anxiety disorder was examined in a randomized wait-list
control trial of 35 adolescents (26 females). Independent evaluators, blind to treatment condition, evaluated participants
at preintervention, postintervention, and 9 months later. Adolescents in the intervention group demonstrated significantly
greater reductions than controls in social anxiety and avoidance, as well as significantly improved overall functioning. In
addition, 67% of treated subjects, compared to 6% of wait-list participants, no longer met criteria for social phobia following
treatment. Findings support the possible efficacy of school-based intervention for facilitating access to treatment for socially
anxious adolescents. 相似文献

This study examined the relationships between perceptions of group members' free riding and group outcomes using Mulvey and Klein's 1998 perceived free riding scale. In a laboratory study, three free riding conditions were created (no free riding, free riding, free riding with justification) in which 97 college students performed two short number-finding tasks as members of temporary ad hoc three-person groups. 55% of the students were male and the average age was 22.9 yr. (SD= 3.0). Participants' perceptions of free riding were negatively related to commitment to the assigned group goal, task performance, and goals for group performance and individual performance. In the condition wherein free riding was justified by low ability, participants set lower goals for their future task performance than did those in the other two conditions. 相似文献
