Vietnam combat veterans assigned diagnoses of PTSD were compared on measures of attention/concentration, new learning, and memory with Army National Guard enlistees who reported no unusual traumatic events or stress-related symptoms. Results showed that PTSD veterans performed more poorly than the comparison sample on a measure of verbal learning, exhibiting less proficient cumulative acquisition across repeated exposures, greater sensitivity to proactive interference, and more perseverative errors. Veterans with PTSD diagnoses also evidenced impairments in word fluency and visual attention/tracking abilities. These preliminary findings suggest that diagnoses of chronic PTSD in combat veterans are associated with cognitive performance deficits, when comparisons are made with military troops judged to be free of stress-related psychopathology. Results are consistent with self-reported complaints of concentration and memory impairments among PTSD-diagnosed clinical samples, thus highlighting the need for continued investigation of the neuropsychologlcal sequelae of prolonged stress exposure. 相似文献

Many open-ended psychotherapy groups have fewer than five members, and fewer than the number the therapist considers necessary for the group to be filled. This paper discusses the rationale for starting such groups and the special dynamics of running them. It then suggests strategies for the therapist to use in maximizing their therapeutic effectiveness. Suggestions are made for further research into the demographic and dynamic aspects of such groups. 相似文献

The hippocampus plays an important role in learning and memory, but the precise nature of that involvement remains uncertain.
Transection of the perforant path, a primary input pathway to the hippocampus, has been shown to produce changes in reaction
to novelty and acquisition of active avoidance; the nature and magnitude of these changes vary with lateral or medial perforant
path damage. In a series of experiments on adult rats, the role of these pathways in spontaneous alternation, exploration,
acquisition and extinction of conditioned responses, passive avoidance, and conditioned taste aversion was investigated. Lateral
transection reduced exploration while medial transection facilitated acquisition of an active avoidance response; no effects
were observed on any other measure. Results are discussed in terms of what perforant path damage might reveal regarding the
interactions of the hippocampus with other brain regions. 相似文献

Two methods for generating video output on multiple video monitors are described. The first method involves splitting the signal from a single video adaptor card-so that multiple video monitors may be attached. Although this method is simple and relatively cost-effective, it is limited to adaptors that produce only digital video signals, thus precluding the use of VGA systems and composite displays. The second method involves the installation and programming of video adaptors: Two sample programs, which control a secondary adaptor by means of either BIOS routines or direct commands via C code, are described. Although more complex, this second method allows output to each display to be controlled independently. Furthermore, output to one screen may consist of graphics information while output to the second screen consists of text. Together, both methods can be used to create an experimental system composed of multiple data-collection stations and an independent experimenter console. 相似文献

The faith and science dialogue has received scholarly attention in the recent past. Within the African landscape at large, the underlying assumption has been that Africans are religious. However, there has been a rising cohort of Africans who are increasingly identified as nonreligious or atheist or agnostic. This research presents a qualitative analysis of the sociocultural factors that affect or influence these minority identities within a pluralistic African context, exploring their emergence and diversities within the African context, with a specific focus on 20 male Kenyan youth who are identified as nonreligious. This research utilized purposive sampling within nonreligious groups and networks. Second, this research aims at exploring how nonreligious identities are constructed, particularly given the concomitant issues surrounding emerging adulthood and new media. This builds up on the theories around youth and identity formation, while foregrounding science and belief as a central theme of study. 相似文献

Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non-edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented-CSA (A-CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A-CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people. 相似文献

Research supports equivalence-based instruction (EBI) and matrix training for increased listening and speaking skills in children with cochlear implants (CI). We incorporated errorless procedures to optimize the EBI and evaluated the effects on the auditory comprehension and verbal responding at-sentences level in six CI children who were readers and showed inaccurate tacting. Subject-verb-object sentences were arranged in two matrices; diagonal combinations were trained and evaluated non-diagonal combinations. EBI included stimulus fading and exclusion to directly teach the dictated sentence-picture matching; written-sentences construction upon dictation also was taught. Probes assessed the derived stimulus-stimulus and stimulus-response relations. All participants learned the auditory-visual discriminations and the exclusion resulted in fewer errors than on a stimulus fading procedure. Five participants formed equivalence classes and increased verbal responding to equivalent stimuli, especially pictures tacting. They also showed recombinative generalization for both matrices. Professionals can incorporate errorless procedures to EBI for improving sentence comprehension, tacting, and productivity in CI children. 相似文献
