系统脱敏法治疗大鼠恐怖症研究

系统脱敏法对矫治恐怖症的行为障碍具有良好的效果,但是对伴随恐怖症同时存在的生理、生化方面的病态反应的治疗未见报告。实验中采用噪音逐步递增的方法使大鼠慢慢适应,分别测量治疗过程中大鼠惊恐、焦虑性行为、生理行为、生化等方面的变化。结果表明：系统脱敏法不仅有效地矫治大鼠的变态行为,对生物学方面具有明显的疗效,而且可以提高动物的应激适应能力。     

The Use of a Personal Trainer to Enhance Participation of Older Adults with Severe Disabilities in a Community Water Exercise Class

Inclusive instruction was provided for three older adults with profound mental retardation in a water exercise class at a local YMCA. The older adults were taught to exercise through the use of systematic prompting. A multiple baseline design across participants with an embedded reversal was used to evaluate the impact of a personal trainer. The three participants performed the exercise, but regressed without the assistance of the trainer, as demonstrated by the reversal. Data collected during peer prompting and maintenance conditions indicated that the participants continued to exercise at levels higher than baseline but lower than with a personal trainer.     

The effect of prompting and reinforcement of activity in elderly demented inpatients

On a ward for 24 psychogeriatric patients, 18 were randomly assigned to three groups with different experimental conditions. The first group was prompted and reinforced for different activities; the second was only prompted; and the third served as a control group. Activities, both the trained ones and others, were continuously monitored throughout the five week study. The results showed a clear increase in the trained activities after training. The prompting condition was effective, and the addition of reinforcement did not add any to the effects. There was no generalization to untrained activities, and the effects did not last at the 1 hr or 21 hr assessments, but was clearly visible at 5 min after training. Time seemed to be more important than place, i.e. the effect ceased with elapsed time, not because of changes in the situation.     

Effects of an audio cueing system on the rate of teacher praise

The effects of automated cueing on teacher praise rate was investigated in one special, one fourth-, and one seventh-grade classroom. After establishing baseline praise rates in each of the three classrooms, two methods for increasing teacher praise rate were introduced according to a multiple-baseline design. During the first phase, two teachers were instructed to count and graph their praise rate during each session. All teachers received auditory cues to prompt praising during another phase. In all cases, introduction of cues markedly increased teacher praise rates, but self-recording was relatively ineffective. An analysis of teacher-praise distributions showed that cues closely controlled teacher praise for two of the three teachers.     

A behavioral analysis of incentive prompts for motivating seat belt use

The seat belt usage of drivers was observed at the entrance to two campus parking lots during morning arrival times. After 11 days of baseline, fliers which prompted seat belt wearing were handed to drivers of incoming vehicles. At one parking lot all fliers offered a chance to win a prize (noncontingent rewards); while at the second lot only those fliers given to seat belt wearers included a chance to win a prize (contingent rewards). After 24 consecutive observation days, these interventions were removed for 14 days of withdrawal. The recording of vehicle license plates enabled an analysis of belt usage per individual over repeated exposures to the experimental conditions. At the lot with the contingent reward intervention, mean belt usage was 26.3% during baseline, 45.7% during treatment, and 37.9% during withdrawal. At the noncontingent reward lot, the mean percentage of belt wearing was 22.2% during baseline, 24.1% during treatment, and 21.8% during withdrawal. The analysis of repeated exposures per individual verified that only contingent rewards influenced substantial increases in belt wearing, and showed that most of the influence occurred after the initial incentive prompt.     

"Flash for life": Community-based prompting for safety belt promotion

A community-based strategy for promoting safety belt use was field-tested in two adjacent rural communities, one populated by a preponderance of students, faculty, and staff of a major university. The intervention involved the front-seat passenger of a stopped vehicle displaying to the driver of an adjacent, stopped vehicle an 11 x 14 inch flash card that read, "PLEASE BUCKLE UP-I CARE." If the driver buckled up, the "flasher" flipped over the card and displayed the message, "THANK YOU." This flash card was shown to 1,087 unbuckled drivers; 82% of these drivers looked at the flash card and 22% of these complied with the buckle-up request. Compliance was not influenced by the age or gender of the "flasher" (young child vs. college student), nor by the gender of the driver; but significantly more drivers in the university town buckled up following the flash card presentation (25% mean compliance in the college town vs. 14% in the other community). To date, over 2,000 individuals have received a buckle-up flash card for their own use.     

Procedural learning across the lifespan: A systematic review with implications for atypical development

This systematic review aimed to investigate procedural learning across the lifespan in typical and atypical development. Procedural learning is essential for the development of everyday skills, including language and communication skills. Although procedural learning efficiency has been extensively studied, there is no consensus yet on potential procedural learning changes during development and ageing. Currently, three conflicting models regarding this trajectory exist: (1) a model of age invariance; (2a) a model with a peak in young adulthood; and (2b) a model with a plateau in childhood followed by a decline. The aims of this study were (1) to investigate this debate on procedural learning across the lifespan by systematically reviewing evidence for each model from studies using the serial reaction time task; and (2) to review procedural learning in autism spectrum disorder (ASD) and specific language impairment (SLI), two developmental disorders characterized by deficits in communication skills, in the light of these models. Our findings on typical development strongly support a model of age-related changes (Model 2a or 2b) and show that mixed findings regarding the developmental trajectory during childhood can be explained by methodological differences across studies. Applying these conclusions to systematic reviews of studies of ASD and SLI makes it clear that there is a strong need for the inclusion of multiple age groups in these clinical studies to model procedural learning in atypical development. Clinical implications of the findings are discussed. Future research should focus on the role of declarative learning in both typical and atypical development.

Mental health practitioners' attitudes towards transgender people: A systematic review of the literature

Background: A systematic review was conducted to critically evaluate and synthesize literature investigating mental health practitioners' attitudes towards transgender people.

Objective: Three primary objectives were outlined; first, establish whether overall attitudes are positive or negative. Second, explore whether training, education or experience influences attitudes and finally, examine participant demographics in relation to attitude trends.

Method: A systematic electronic search was carried out in March 2017 using Medline, PsycINFO, PsycArticles, CINAHL, ASSIA, and Web of Science electronic databases. Manual citation and ancestral searches were conducted on identified papers. Qualitative, quantitative and mixed method studies were eligible for inclusion. A total of 13 papers of mixed quality were identified.

Results: Existing literature is limited to cross-sectional, quantitative data and fails to investigate differences between implicit and explicit attitudes. Small to moderate convenience samples reduce the generalizability of data. Overall attitudes were positive although negative attitudes were more frequent in male, Caucasian, heterosexual, religious, conservative mental health professionals.

Conclusions: Refined scales are needed to address the unique heterogeneity within transgender populations. Future research should focus on how attitudes impact care provided and employ longitudinal designs to explore the sustainability of targeted attitudinal training.
