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

Progressive-interval performances are described using measures that have proven to be successful in the analysis of fixed-interval responding. Five rats were trained with schedules in which the durations of consecutive intervals increased arithmetically as each interval was completed (either 6-s or 12-s steps for different subjects). The response patterns that emerged with extended training (90 sessions) indicated that performances had come under temporal control. Postreinforcement pausing increased as a function of the interval duration, the pauses were proportional to the prevailing duration, and the likelihood of the first response within an interval increased as the interval elapsed. To assess the resistance of these patterns to disruption, subjects were trained with a schedule that generated high response rates and short pauses (variable ratio). When the progressive-interval schedule was reinstated, pausing was attenuated and rates were elevated, but performances reverted to earlier patterns with continued exposure. The results indicated that temporal control by progressive-interval schedules, although slow to develop, is similar in many respects to that for fixed-interval schedules. 相似文献

Four pigeons were exposed to autoshaping procedures in which an 8-second light on a response key was followed by food. Pecks on the key had no scheduled consequences. Subjects were also exposed to negative automaintenance procedures in which a peck on the illuminated key canceled the following food. The intertrial interval varied from an average of 7 seconds to an average of 232 seconds in different conditions. Rate of responding usually changed within sessions during autoshaping. Responding also changed within sessions for the 1 subject that responded during negative automaintenance. The within-session patterns of responding were flatter, peaked later, and were more symmetrical around the middle of the sessions at lower rates of food presentation, regardless of whether subjects responded on autoshaping, negative automaintenance, or previously reported variable-interval schedules. These results imply that similar variables produce within-session changes in responding during both classical (Pavlovian) and operant conditioning procedures. 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

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

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

Not as Different as We Want to Be: Attitudinally Consistent Trait Desirability Leads to Exaggerated Associations Between Personality and Sociopolitical Attitudes

Research connecting sociopolitical attitudes to personality typically relies exclusively on self‐report measures of personality. A recently discovered mechanism of bias in self‐reports highlights a particular challenge for this approach. Specifically, individuals tend to report exaggerated levels of a trait to the extent that they view that trait as desirable. In a community sample of 443 participants, differences in sociopolitical attitudes were associated with differences in the extent to which individuals provided biased self‐reports for a given trait (relative to trait levels indicated by peer‐report or an objective measure) as well as differences in views of the desirability of that trait. Further, the tendency to misrepresent traits in a manner consistent with one's sociopolitical attitudes was mediated by differences in views of trait desirability. Thus, although meaningful personality differences exist among those with differing sociopolitical attitudes, those differences may not be as large as people with opposing sociopolitical attitudes might like them to be. 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.
