Stereotypic responding and social behaviors of three profoundly retarded children were measured before and during application of a DRL contingency for stereotypic responding. A variant of the standard DRL procedure, spaced responding DRL, was used, in which reinforcement is delivered following a response if that response has been separated from the previous response by at least a fixed minimum time interval. Three children were treated by using a reversal design. Results showed that: (a) during baseline sessions, the children engaged in high rates of stereotypic responding and very low rates of appropriate social behavior; and (b) during DRL sessions, appropriate behavior increased markedly as stereotypic responding was reduced. The data suggest that spaced responding DRL may be effective in increasing appropriate social behavior as well as in reducing stereotypic responding. 相似文献

Two different definitions of behavioral contrast have been used for multiple schedules. One, interschedule, definition identifies contrast as changes in the rates of responding which occur when subjects move from one multiple schedule to another. The other, intraschedule, definition emphasizes changes in the rates of responding which occur relative to a baseline rate of responding. The baseline is the rate of responding emitted during a multiple schedule that supplies equal rates of reinforcement in the two components. The distinction between these two definitions is important for empirical and theoretical reasons. For example, theoretical confusion has arisen when the interschedule definition has been used to test and reject theories which implicitly define contrast by the intraschedule definition. 相似文献

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation. 相似文献

In three experiments, 8 human subjects participated in a study of the effects of smoked marijuana on progressive-interval schedule performance. A two-component chained progressive-interval fixed-interval schedule of point delivery was used. In the progressive-interval component, the interval length began at 20 s and increased either geometrically or arithmetically (by either 20 s, 40 s, 80 s, 100 s, or 160 s) on each subsequent interval. After this interval elapsed, a single button press produced the fixed-interval component, with a total of five reinforcers of varying magnitude ($0.05, $0.20, or $0.40) available on a fixed-interval 20-s schedule. After the five reinforcer deliveries, the schedule returned to the initial progressive-interval component. Several relationships were found among rates of responding, postreinforcement pauses and drug administration in the progressive-interval component: (a) Postreinforcement pauses increased as the temporal requirements of the progressive-interval schedule increased; (b) rates of responding during successive progressive-interval components rapidly decreased to low rates of responding after the first few progressions; (c) postreinforcement pauses decreased systematically as dose of smoked marijuana increased; and (d) rates of responding increased after smoking active marijuana but not after smoking placebo cigarettes. Results are discussed in the context of behavioral control and relevance to other studies that have investigated the effects of smoked marijuana on schedule performance. 相似文献

Previous studies on naming have presented the object and its name simultaneously during both training and testing, and thus the training component may establish a transformation of function directly between the object and the name. Successful tests for listener naming may thus not require the emergence of a novel (entailed) transformation of function. The current study aimed to control for this possibility by presenting the object and the name sequentially and nonsimultaneously. Eight typically developing toddlers participated in the current study. During name training, objects and names were presented nonsimultaneously, and all participants failed to emit listener-naming responses during the first test session. Subsequently, 4 participants received multiple exemplar training, which led to improvements in listener naming for all 4; and speaker naming for only 1 participant. As a control condition, the remaining 4 participants were tested repeatedly, without multiple exemplar training, and did not show any consistent improvements in their listener or speaker performances. Multiple exemplar training thus appeared to be effective in establishing generalized listener responses, which involved generating entailed transformation of functions. The strategy of using nonsimultaneous stimulus presentations could allow for greater precision in identifying the behavioral processes involved in listener-naming. 相似文献

Despite decades of research on the role of socially desirable responding (SDR) in hiring contexts, it remains unclear whether job applicant SDR is related to future employee performance. Drawing on a large sample of 1,084 retail sales employees and their original job application data, this study examined the predictive validity of two operationalizations of SDR: (a) impression management captured using a personality scale and (b) overclaiming familiarity with a list of products that were directly relevant to the job. Neither measure was used to inform the hiring decisions. Results showed that job applicant impression management and overclaiming were unrelated to four indicators of future sales performance as employees. Implications for organizational selection policies involving applicant SDR are discussed. 相似文献

We evaluated a procedure for teaching two children, one typically developing and one with autism, a higher‐order generalized operant response class of unscrambling sight words. The procedures were efficacious in teaching the participants to unscramble words appearing in isolation and in the context of a sentence, with 98% of the presented discriminative stimuli novel to the participants. 相似文献

One adult female chimpanzee (Pan troglodytes) was trained to respond serially to three arabic numerals between 1 and 9, presented on a cathode-ray-tube (CRT) screen.
To examine the factors affecting her sequential responding behavior, wild-card items were added to the three-item sequences.
When this wild-card item remained until the subject responded to the last numeral (i.e., the terminator condition), her response
to the terminator at each point of the sequence was controlled by the ordinal distance between numerals. Thus, the number
of responses to the terminator increased as the ordinal distance between numerals increased. When the wild-card item was eliminated
by the subject’s response (wild-card conditions), the probability of responses to the wild card before the first numeral increased
as a function of the serial position of the first numeral. These results were consistent with previous studies of response
time and suggest both serial position and symbolic distance effects. It is suggested that the subject might form the integrated
9-item linear representations by training of possible subsets of three-item sequences. Knowledge concerning the ordinal position
of each numeral was established through this training.

Despite the central status of avoidance in explaining the etiology and maintenance of anxiety disorders, surprisingly little behavioral research has been conducted on human avoidance. In the present paper, first we provide a brief review of the empirical literature on avoidance. Next, we describe the implications of research on derived relational responding and the transformation of functions for a contemporary behavioral account of avoidance, before providing several illustrative research examples of laboratory-based analogues of key clinical treatment processes. Finally, we suggest some challenges and opportunities that lie ahead for behavioral research on anxiety and avoidance. 相似文献

The psychometric properties of the new German versions of the Driver Skill Inventory (DSI) and the Driver Social Desirability Scales (DSDS) were examined. The DSI is a self-report measure assessing perceptual-motor skills and the safety motive as two important aspects of driving behavior. Self-report measures, however, are susceptible to socially desirable responding (SDR) which is why both general and specific driving-related SDR scales have been developed: Based on the Balanced Inventory of Desirable Responding (BIDR), the DSDS taps Driver Impression Management and Driver Self-Deception as two important aspects of SDR. In two validation studies with less experienced (N = 130) and experienced drivers (N = 1199), both inventories showed the expected two-factor structure and satisfactory internal consistency. In Study 1, self-ratings were compared with and confirmed by peer-ratings. In both studies, we accumulated evidence of convergent and discriminant validity for the German version of the DSI by correlating it with demographic, driving-specific, and personality measures, including the Big Five, Type A behavior, and sensation seeking. The DSI seemed to be only marginally contaminated by SDR. 相似文献
