Psittacines are generally considered to possess cognitive abilities comparable to those of primates. Most psittacine research has evaluated performance on standardized complex cognition tasks, but studies of basic cognitive processes are limited. We tested orange-winged Amazon parrots (Amazona amazonica) on a spatial foraging assessment, the Hamilton search task. This task is a standardized test used in human and non-human primate studies. It has multiple phases, which require trial and error learning, learning set breaking, and spatial memory. We investigated search strategies used to complete the task, cognitive flexibility, and long-term memory for the task. We also assessed the effects of individual strength of motor lateralization (foot preference) and sex on task performance. Almost all (92 %) of the parrots acquired the task. All had significant foot preferences, with 69 % preferring their left foot, and showed side preferences contralateral to their preferred limb during location selection. The parrots were able to alter their search strategies when reward contingencies changed, demonstrating cognitive flexibility. They were also able to remember the task over a 6-month period. Lateralization had a significant influence on learning set acquisition but no effect on cognitive flexibility. There were no sex differences. To our knowledge, this is the first cognitive study using this particular species and one of the few studies of cognitive abilities in any Neotropical parrot species.  相似文献

Historically, consumers of mental health services have not been given meaningful roles in research and change efforts related to the services they use. This is quickly changing as scholars and a growing number of funding bodies now call for greater consumer involvement in mental health services research and improvement. Amidst these calls, community‐based participatory research (CBPR) has emerged as an approach which holds unique promise for capitalizing on consumer involvement in mental health services research and change. Yet, there have been few discussions of the value added by this approach above and beyond that of traditional means of inquiry and enhancement in adult mental health services. The purpose of this paper is to add to this discussion an understanding of potential multilevel and multifaceted benefits associated with consumer‐involved CBPR. This is accomplished through presenting the first‐person accounts of four stakeholder groups who were part of a consumer‐involved CBPR project purposed to improve the services of a local community mental health center. We present these accounts with the hope that by illustrating the unique outcomes associated with CBPR, there will be invigorated interest in CBPR as a vehicle for consumer involvement in adult mental health services research and enhancement.  相似文献

Discrete‐trial instruction (DTI) is a behavioral method of teaching young children with autism spectrum disorders (ASD) that has received a significant amount of research support. Because of a lack of qualified trainers in many areas of the world, researchers have recently begun to investigate alternative methods of training professionals to implement behavioral teaching procedures. One promising training method is interactive computer training, in which slides with recorded narration, video modeling, and embedded evaluation of content knowledge are used to teach a skill. In the present study, the effectiveness of interactive computer training developed by Pollard, Higbee, Akers, and Brodhead (2014), translated into Brazilian Portuguese, was evaluated with 4 university students (Study 1) and 4 special education teachers (Study 2). We evaluated the effectiveness of training on DTI skills during role‐plays with research assistants (Study 1) and during DTI sessions with young children with ASD (Studies 1 and 2) using a multiple baseline design. All participants acquired DTI skills after interactive computer training, although 5 of 8 participants required some form of feedback to reach proficiency. Responding generalized to untaught teaching programs for all participants. We evaluated maintenance with the teachers in Study 2, and DTI skills were maintained with 3 of 4 participants.  相似文献

What does it take to find a member of a different race attractive? In this research, we suggest that for Whites, attraction to Asians may be based, in part, on stereotypes and variations in Asians' racial appearance. Study 1 reveals that Asians are stereotyped as being more feminine and less masculine than other racial groups-characteristics considered appealing for women but not for men to possess. Study 2 examines how variation in racial appearance, phenotypic prototypicality (PP), shapes the degree to which Asians are gender stereotyped and how PP relates to perceptions of attractiveness. Higher PP Asian men are perceived as being less masculine and less physically attractive than lower PP Asian men. These findings inform theory on how within-group variation in racial appearance affects stereotyping and other social outcomes.  相似文献

Health locus of control has been shown to influence how individuals approach their health and health-related decisions. The present study examined the variables predictive of older adults’ health locus of control. A total of 261 adults aged 54–84 years completed a questionnaire about their health, approach to health, and background information about themselves. The results revealed that demographic indicators, health-related variables, and psychological variables—particularly health risk tolerance, future time perspective, health self-efficacy, and emotional instability—were related to older adults’ health locus of control. Findings have implications for programs aimed at modifying older adults’ health locus of control.  相似文献

In 1966, the social scientists of the Simulmatics Corporation arrived in Saigon. Tasked by the Pentagon with helping to pacify South Vietnam, they conducted political and social psychological research on Viet Cong defectors, government soldiers, and Vietnamese villagers. This essay argues that Simulmatics's work captures some of the ironies of Cold War social science: its tendency to mask militarization behind the rhetoric of peaceful nation-building, its blurring of data collection and intelligence gathering, and its ambitious dedication to revealing the unseen contents of hearts and minds while remaining ignorant of the historical, cultural, and linguistic contexts in which its subjects lived.  相似文献

Gamma-hydroxybutyrate (GHB) is a drug with significant abuse potential. The present study aimed to assess the relative value of escalating doses of GHB to current GHB users via the Multiple Choice Procedure (MCP), and to validate that the dose rated highest with the MCP would be self-administered at a greater rate than placebo. Participants were 5 current GHB users who were not currently trying to stop using GHB. To examine the value of escalating doses of GHB, the following doses of GHB were used: 0 (placebo), 12.5, 25, 37.5, and 50 mg/kg. Participants typically assigned higher doses of GHB had higher crossover points on the MCP. During choice sessions, participants made repeated choices between administering GHB, placebo or nothing. All participants selected GHB exclusively (5 out of 5 instances) except for one participant who selected GHB on 4 out of 5 instances, thus 96% (i.e., 24/25) of choices were for active GHB. Based on these data, GHB appears likely to function as a dose-dependent reinforcer for humans based on our sample.  相似文献

The trajectory toward tenure is complex and arduous, and it requires one to balance attention among diverse and competing demands. It is not surprising that many newly appointed assistant professors report struggling with this process. Borrowing from family and ecological systems theories, we proffer a framework that may help junior faculty members—defined in this article as tenure-earning assistant professors—learn about the tenure-earning process as they navigate through the university system and beyond. We also describe and clarify the many parts of the tenure-earning process, including the roles, responsibilities, and multiple contexts that must be considered concurrently by junior faculty members as they progress through the stages of their tenure-earning appointment in the academy.  相似文献
