We describe intervention with 2 adolescent male students who had autism spectrum disorder (ASD) and resisted haircutting performed by care providers at a residential school. The students were exposed to a graduated hierarchy of steps including the presence of hair clippers, and increased duration of hair clippers against their scalp and hair. Edible reinforcement was presented contingent on completion of a step without interfering behavior. Both students learned to tolerate all of the steps in the graduated hierarchy and a full haircut with maintenance at 2-, 4-, and 6-month follow-up. The study supports previous tolerance-training research with children and youth who have intellectual and developmental disabilities and resist personal care and hygiene routines. 相似文献

This paper reflects on experience gained from presymptomatic testing for Huntington disease. An approach is presented which considers the role of the clinician and aims of the interview. Irrespective of the disease being tested for, it is suggested that the psychological aim of presymptomatic testing is to foster emotional insight and understanding that will help clients in their decision-making process about testing and their subsequent adjustment to the result. Based on these aims the process of presymptomatic testing, counseling is considered in terms of clarification, consideration, education, and reflection, followed by decision making. Practical approaches are discussed and illustrated with clinical examples. 相似文献

The last spelled letter often indicates the sex of first names. Most female names end with the last letter a, e, or i. Female names are distinctive and therefore easy to identify because of the small number of predominantly female endings. Most male names end with one of 19 last letters. Two last letters, h and y, occur with similar frequency for both sexes. The cultural tradition of higher status for men contributes to the avoidance of predominantly female last letters for male names. A female name with a predominantly male last letter therefore occurs more often than a male name with a predominantly female last letter. The findings were obtained from the 500 most frequent first names given to males and females in Pennsylvania in 1990. 相似文献

The authors use the concept of existential depression as the basis for a set of treatment interventions that are often useful to the relocated Appalachian family and describe the use of a number of different network intervention strategies for use with such families and the existential reasons for their use.Both are of Appalachian heritage and have extensive experience in family practice with the Appalachian family. 相似文献

Three experiments using multiple schedules of reinforcement explored the implications of resistance-to-change findings for the response-reinforcer relation described by the law of effect, using both steady-state responding and responding recorded in the first few sessions of conditions. In Experiment 1, when response-independent reinforcement was increased during a third component, response rate in Components 1 and 2 decreased. This response-rate reduction was proportionately greater in a component in which reinforcer magnitude was small (2-s access to wheat) than in the component in which it was large (6-s access to wheat). However, when reinforcer rates in the two components were varied together in Experiments 2 and 3, response-rate change was the same regardless of the magnitude of reinforcers used in the two components, so that sensitivity of response rates to reinforcer rates (Experiment 2) and of response-rate ratios to reinforcer-rate ratios (Experiment 3) was unaffected by the magnitude of the reinforcers. Therefore, the principles determining resistance to change, described by behavioral momentum theory, seem not to apply when the source of behavior change is the variation of reinforcement contingencies that maintain the behavior. The use of extinction as a manipulation to study resistance to change is questioned. 相似文献

A local independence latent structure model, which assumesm latent classes, requires a minimum of 2m-1 items for the solution of the 2m
2 latent parameters. If one adds 3 items to the test and if one assumes local dependence between pairs of items, thereby adding
additional latent parameters,
ij
, representing the association between itemsi andj, then it is possible to obtain estimates for all of the latent parameters: latent class frequencies latent probabilities, and measures of association between pairs of items. The solution consists of (1) forming (m + 1) × (m + 1) matrices of manifest data, which are singular, (2) solving for the
ij
in equations that result from the singularity of the data matrices, (3) correcting the manifest data by removing the contamination due to local dependence, and (4) estimating the remaining latent parameters from the corrected data, using methods outlined in earlier literature. 相似文献
