It has been suggested that intermittent reinforcement may be of value in reducing the rate of relapse in bedwetting conditioning therapy. An experiment was conducted with 30 enuretic boys to examine acquisition and extinction parameters of continuous (100%), intermittent (70% variable ratio), and “placebo” (0%) reinforcement schedules. Reinforced trials were administered as in the typical Mowrer conditioning procedure. Non-reinforced trials were achieved by means of a time delay with the subsequent alarm being activated in the parent's room rather than in the child's room. These procedures required the development of a new conditioning device which could be programmed to automatically administer the desired schedule of reinforcement. The results of the field investigation revealed that continuous reinforcement (CR) and intermittent reinforcement (IR) groups attained acquisition in approximately the same number of trials and with essentially the same success rate. Relapse rate was significantly greater in the CR group than in the IR group. The placebo group showed no improvement over the 6 weeks of treatment. The results of this study may be interpreted as supporting the tenet that relapse can be viewed and treated as an extinction of the acquired response. 相似文献

A type of paired-associate task was given to 64 kindergarteners and 64 fifth-graders. In four conditions both linguistic and pictorial stimuli were presented simultaneously. In one condition, both a linguistic and pictorial relationship between two objects was depicted; in a second, only the linguistic aspect of the stimuli depicted a relationship; in the third condition, only the picture was relational; and in the fourth, neither the sentences nor the pictures portrayed a relationship between the objects. The results indicate that a relationship in both modes facilitated recall more than the presentation of a relationship in only one mode. A relationship in either mode enhanced recall more than no relationship at all. There were general significant age and IQ effects. The results are interpreted as favoring a duo-system model, with both representation and comprehension occurring within the context of relatively independent systems. 相似文献

An experimental study was conducted to examine phonetic and phonemic deficits in the speech production of aphasics. Subjects included four Broca's aphasics, four Conduction aphasics, five Wernicke's aphasics, one nonaphasic dysarthric patient, and four normal controls. The subjects read a list of words containing word-initial stop consonants which were subsequently measured acoustically for voice-onset time. The results showed that Broca's aphasics exhibit a more severe production disorder than Conduction aphasics who in turn exhibit a more severe disorder than Wernicke's aphasics, in accord with clinical observations. In addition, although Broca's aphasics produced both phonetic and phonemic errors, the results showed that they have a pervasive phonetic disorder which affects their correct target productions as well as the total number of phonetic errors produced. This deficit however seems to be a speech deficit rather than a low-level motor control problem. In contrast, the Wernicke's aphasics show a deficit characterized by isolated phonemic mistargeting errors. Finally, the pattern of productions for the Conduction aphasics indicates that some patients show a predominantly phonetic disorder similar to the Broca's aphasics and others show predominantly a phonemic disorder similar to the Wernicke's aphasics. 相似文献

Cognitive Behavioral Therapy for Psychosis (CBTp) is an evidence-based psychotherapeutic intervention (EBPI) for adults with schizophrenia spectrum disorders that remains under-implemented in the United States (U.S.). There has been little empirical attention on implementation and dissemination strategies for this EBPI. The Learning Collaborative (LC) model is a method of implementing evidence-based practices across agencies and geographic regions that may facilitate CBTp implementation and dissemination in the US.We applied the LC model in an attempt to enhance the accessibility of CBTp in community mental health settings statewide. Providers (N = 56) from 12 agencies voluntarily participated in an in-person, CBTp workshop followed by 6 months of biweekly phone-based consultation sessions (Phase 1). Twenty-one providers opted to participate in an additional 6-month CBTp LC immediately following completion of the initial CBTp LC (Phase 2). Adoption, penetration, provider-perceived skill development, fidelity, as well as provider-perceived implementation barriers were re-assessed during and 6 months after completion of Phase 2.One year after the completion of the Phase 2 LC, 21% of the original trainee group across 3 of the 12 participating agencies continued to offer CBTp to clients. CBTp trainees were treating between one and two clients each. Self-assessed CBTp skills improved modestly over the Phase 2 consultation period. On average, both clinicians and supervisors reached an acceptable fidelity score on the sessions reviewed. Participating providers identified multiple barriers to CBTp implementation, including features of the training and consultation, the agency, the intervention itself, and psychosocial and clinical challenges associated with the client population.Few CBTp implementation studies have applied a framework to CBTp implementation. The authors adapted the LC model in an attempt to promote adoption of CBTp in community mental health clinics across a large, populous state with poor access to mental health services. Identified challenges and recommendations should be considered in future implementation efforts. 相似文献

The numerous mechanisms of behavior change in infant development are sometimes difficult to distinguish. Although it is agreed that elicitation and reinforcement both influence infant learning, the distinction between these two learning mechanisms was clarified in response to K. Bloom's (1984, Journal of Experimental Child Psychology, 38, 93-102) commentary. The theoretical and methodological assumptions of an functional analysis of infant behavior were made explicit in the context of the C. L. Poulson study (1983, Journal of Experimental Child Psychology, 36, 471-489). The rationale for the use of DRO schedules to control for elicitation effects of continuous reinforcement and the inadequacy of noncontingent schedules for this purpose were also discussed. 相似文献

The expectation of cooperative future interaction (ECFI) encouraged especially high joint benefit (the total of the two bargainers' individual outcomes) when resistance to yielding was high, but especially low joint benefit when resistance to yielding was low. Process data suggest that this finding can be explained as follows: When resistance to yielding is high, ECFI encourages problem solving and reduced contentious behavior; when resistance to yielding is low, ECFI encourages a collapse of aspirations. The results support Filley's (1975) dualconcern model and cast doubt on Deutsch's (1973) blanket assertion that a cooperative process leads to constructive conflict resolution. 相似文献

Second and fifth graders memorized each of two lists of words that differed in category representativeness. In addition, they received one of three memory instructions: standard free recall, repetition, or categorial processing. Recall performance was about equal for standard vs repetition, and both were lower than category processing, especially with the highly representative items. Age did not enter this interaction, so it is concluded that at both age levels, the accessibility of categorial information influences children's use of it. This suggests multiple types of possible production deficiencies. 相似文献

The fluent speaking rate of nine adult male stutterers was compared before and after stuttering intervention. The subjects, ranging in age from 18 to 37 yr (mean, 25 yr, 3 mo), exhibited mild to severe stuttering prior to treatment. The only rate reduction strategy taught to subjects during intervention was to slow the first phoneme or syllable of sentences spoken. In addition, however, subjects significantly reduced their overall rate as determined by measurements made of their fluent speech at the middle of sentences, as well as overall sentence durations (excepting the first word of utterances). The data from this investigation are interpreted relative to the facilitation/simplification hypothesis. 相似文献

Stuttered and nonstuttered phonemes of 20 adult males were analyzed for distinctive feature patterns using the Chomsky-Halle system. The features (+ consonantal), (- voice), (+ continuant), and (- strident) occured significantly more often in stuttering than in nonstuttering instances. Results suggest that adult stuttering is most likely to occur when the primary sites of tension and discoordination are lingual and laryngeal and when the speaker must shift from (- voice) to (+ voice). 相似文献
