Shoplifting and employee theft constitute a major problem for retailers. Previous research has described techniques for effectively reducing either type of theft but has not addressed the problem of thefts of unspecified origin. In a grocery store we evaluated the effect of identifying for employees frequently stolen products from three groups of items and graphing, twice weekly in the lunchroom, losses for the separate groups. After the products were identified and losses graphed, thefts from the three groups dropped from eight per day to two per day.  相似文献

An interrupted time-series analysis of local directory-assistance calls in the Cincinnati area from 1962 to 1976 revealed a significant reduction in the daily frequency of calls after charges were introduced in 1974. No reductions occurred in the daily frequency of long-distance directory-assistance calls, which remained free. The results attest to the efficacy of response-cost procedures with large subject populations in the natural environment. The applicability of response-cost procedures to social and business problems is discussed.  相似文献

Tics are rapid, repetitive, stereotyped movements or vocalizations that arise from neurobiological dysfunction and are influenced by environmental factors. Although persons with tic disorders often experience aversive social reactions in response to tics, little is known about the behavioral effects of such consequences. Along several dimensions, the present study compared the effects of two treatments on tics: response cost (RC) and differential reinforcement of other behavior (DRO). Four children with Tourette syndrome were exposed to free-to-tic baseline, DRO, RC, and quasibaseline rebound evaluation conditions using an alternating treatments design. Both DRO and RC produced substantial decreases in tics from baseline levels. No differential effects of DRO and RC contingencies were seen on self-reported stress or in the strength of the reflexive motivating operation (i.e., premonitory urge) believed to trigger tics, and neither condition produced tic-rebound effects. Implications of these findings and directions for future research are discussed.  相似文献

The present study examines the productivity of task groups in relation to the personality resources of its members and its two dimensions of group process: task focus and shared exchange. It is hypothesized that the depth of a group's personality resources impacts upon productivity both directly through the application of its member's personality resources to successful group outputs, and indirectly through the mediating agency of group process variables that also contribute separately to successful group outputs. To test these hypotheses, the performance of 43 groups in a 3-month social psychology class was measured across three course assignments. This averaged performance score was related to the groups' process scores and to their total levels of personality resources measured by a comprehensive personality inventory administered at the beginning of the groups' life. Using multiple regression, we found that a group's performance was predicted by total member intellect, openness (negatively), and emotional stability (negatively). Blocked regression revealed that group intellect exercised a direct effect upon group performance, but that the effects of group openness and group emotional stability on performance were mediated through the group's two group processes of task focus and shared exchange. It is hoped that this demonstration of a two-step approach to studying the impact of group member's personality through its direct effects on group performance and its indirect effect on performance-linked aspects of group process will be extended to other types of personality measures, and to other types of groups addressing different tasks in other cultural settings.  相似文献

We compared the effects of Lag 0 and Lag 1 schedules of reinforcement on children's responses naming category items in a group context and subsequent responses emitted during individual testing in which the schedule of reinforcement remained Lag 0. Specifically, we measured response variability and novel responses to categories for 3 children who demonstrated the lowest level of variability during an initial individual Lag 0 testing session. An additional 3 children who emitted a high level of variability during initial individual Lag 0 testing sessions served as peers during group sessions. Results showed that participants conformed to the Lag 1 schedule and were more likely to repeat peer responses in the group and during individual testing in the Lag 1 condition. Furthermore, the reinforcement schedule in effect during group sessions affected participants’ varied responses during individual testing, during which the reinforcement schedule remained unchanged.  相似文献

Multiple sleep problems of a 2-year-old girl improved following treatment with a faded bedtime with response cost procedure (Piazza & Fisher, 1991). These results extend the literature by implementing treatment in a home setting with a nondisabled child using the parents as therapists.  相似文献

A reinforcement system utilizing instructions, modelling, feedback, and group reinforcement was employed in an attempt to reduce disruptive noise on three university residence halls. A fourth hall received the same treatment program without the reinforcement component. Noise scores were determined by recording the number of discrete noise occurrences over a criterion decibel level. On all four residential floors, noise scores during treatment conditions were lower than initial and final baseline levels. Additionally, periods of noise reduction corresponded to the changing criterion multiple-baseline and reversal designs utilized. Pre- and posttreatment questionnaire responses from the three reinforcement floors paralleled changes in objective noise data. At posttreatment, residents reported less noise disturbance of study and sleep and more control over the noise situation and floor problems in general. These results indicated that a comprehensive behavior-modification treatment package was effective in reducing disruptive noise in university residence halls. Difficulties in data collection and anomalies in the data are discussed. Future directions for field-based behavior-modification research are outlined.  相似文献

The aim of the present study was to evaluate whether a short parent-training program (PT) reduces risk factors related to development of childhood socio-emotional and behavior problems in a non-clinical community sample. Data were obtained from parents in a randomized controlled trial (RCT) on PT for children aged 2 to 8 years (N=186) at pre-intervention, post-intervention and one-year-follow up. There were significant differences in the changes in the two groups, with reductions in harsh parenting and child behavior problems, an enhancement of positive parenting and of the parents' sense of competence in the intervention group. The effects on parenting and parents' satisfaction all lasted through one-year follow up. Our findings suggests that a shortened version of a well-structured parenting intervention, The Incredible Years program, implemented in primary care at community level, reduces harsh parenting and strengthens positive parenting and parents' sense of competence, as reported by the parents. Issues related to a public health approach to promote positive parenting are discussed.  相似文献

Adults with mental retardation in a group home received popcorn or coffee reinforcers for sorting plastic dinnerware. In Part 1 of the experiment, reinforcers were dispensed according to a variable-interval 60-s schedule for sorting dinnerware of one color and according to a variable-interval 240-s schedule for sorting dinnerware of a different color in successive components of a multiple schedule. Sorting rates were similar in baseline, but when a video program was shown concurrently, sorting of dinnerware was more resistant to distraction when correlated with a higher rate of reinforcement. In Part 2 of the experiment, popcorn or coffee reinforcers were contingent upon sorting both colors of dinnerware according to variable-interval 60-s schedules, but additional reinforcers were given independently of sorting according to a variable-time 30-s schedule during one dinnerware-color component. Baseline sorting rate was lower but resistance to distraction by the video program was greater in the component with additional variable-time reinforcers. These results demonstrate that resistance to distraction depends on the rate of reinforcers obtained in the presence of component stimuli but is independent of baseline response rates and response–reinforcer contingencies. Moreover, these results are similar to those obtained in laboratory studies with pigeons, demonstrating that the determination of resistance to change by stimulus–reinforcer relations is not confined to controlled laboratory settings or unique to the pigeon.  相似文献

A multiple single‐case research design was used to explore changes in teacher‐reported behaviors of 15 children who completed a motivational interviewing–based counseling program in a disciplinary alternative education school. Findings indicated that 7 children made a moderate to large improvement in their classroom behaviors while participating in the program. Students’ self‐motivational statements and self‐reported readiness to change were related to actual teacher‐rated behavioral changes. Implications for future research and counseling practice were discussed.  相似文献

Most research on the relationship between personality and overall job performance assumes linearity and homoscedasticity. This study investigated the prevalence and nature of nonlinearities and heteroscedasticies in relationships between conscientiousness and supervisory ratings of overall job performance across five independent samples using both concurrent (k = 4) and predictive (k = 1) designs. Hierarchical polynomial regression analyses found evidence of robust linear effects but no evidence of statistically significant quadratic or cubic effects. A statistically and practically significant heteroscedastic effect was found in only one sample such that lower errors of prediction were evidenced in the ends in comparison to the middle of the bivariate distribution. Implications for the use of conscientiousness in personnel selection are suggested. Limitations of the current study and directions for future research are noted.  相似文献

Response sequences emitted by five Long-Evans rats were reinforced under a two-component multiple schedule. In the REPEAT component, food pellets were contingent upon completion of a left-left-right-right (LLRR) sequence on two levers. In the VARY component, pellets were contingent upon variable sequences (i.e., a sequence was reinforced only if it differed from each of the previous five sequences). The rats learned to emit LLRR sequences in the REPEAT component and variable sequences in VARY. Intraperitoneal injections of ethanol (1.25, 1.75, and 2.25 g/kg) significantly increased sequence variability in REPEAT, thereby lowering reinforcement probability, but had little effect on sequence variability in the VARY component. These results extend previous findings that alcohol impairs the performance of reinforced repetitions but not of reinforced variations in response sequences.  相似文献

Theory and research on status attainment in work groups primarily focuses on members’ abilities and characteristics that make them appear competent as predictors of their status in the group. We complement the abilities perspective with a social identity perspective by arguing that another important determinant of a member’s status is based on the extent to which the member serves the group’s interests. Specifically, we assert that a member’s identification with the group affects performance on behalf of the group, which in turn affects other members’ assessment of the member’s status. We test this social identity perspective on status attainment by studying the influence of members’ group identification on their performance and status in the group, while controlling for the members’ abilities and status characteristics. In a three-wave longitudinal field study following 33 work groups during a six-month group project, we find that members’ identification enhances their performance on behalf of the group, which in turn increases their status within the group. As such, our study advances insights in the determinants of status attainment in work groups and points to the relevance of the social identity approach for research on the antecedents of status in work groups.  相似文献

Effects of incorrect or partial implementation (poor treatment integrity) on response cost are largely unknown. We evaluated reduced treatment integrity during response cost on rates of 2 concurrently available responses. College students earned points by clicking on either a black circle or a red circle on a computer screen. Experiment 1 compared 2 types of treatment‐integrity failures (omission and commission errors) across 2 levels of integrity (20% and 50%). Compared to 100% integrity conditions, omission errors did not suppress responding to the same extent, and commission errors reduced target responding but also decreased rates of alternative behavior. Experiment 2 compared the effects of 20% and 50% omission errors within subjects. Implementation at 50% integrity adequately suppressed responding, but treatment effects were lost at 20% integrity. There may be a critical level at which response cost must be implemented to suppress responding, which has important implications for application.  相似文献

We examined whether a group contingency increased engagement during elementary school physical education sessions. The intervention employed procedures (explicit instruction, goal setting, and reinforcement) drawn from the first tier of classwide function‐related intervention teams (CW‐FIT; Wills et al., 2009). Results showed salutary increases in engagement that corresponded with the teacher's implementation.  相似文献

The inhalation of 7.5% CO2 has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO2 gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO2 compared with air, indicating CO2-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO2 inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.  相似文献

The article reports on research designed to test Australian attitudes towards helping impoverished members of the Australian society, in particular, indigenous and homeless people. Australian university students completed a questionnaire to measure their attitudes towards helping homeless and indigenous people under conditions that primed a common Australian identity. The findings showed that priming an inclusive identity led to relatively stronger intentions to help indigenous Australians but not homeless people. It was also found that participants preferred to endorse more autonomy than dependency help to both indigenous and homeless Australians. Whereas the findings indicate that helping intentions towards those living with poverty may be accentuated by priming a common in‐group, they also imply that helping attitudes vary with the type of help being sought and the way people perceive the cause of someone's poverty.  相似文献

This research examines the moderating influences of trust in superiors and influence of superiors as elements of an organization communication system on the association between individual-job congruence and job performance/satisfaction. Data from 302 employees were used to assess the research design variables of growth need strength, job scope, trust in superiors, influence of superiors, job performance, and job satisfaction. Moderated regression analysis gave weak support to trust and influence as moderators of the association between individual-job congruence and both job performance and satisfaction. The results did, however, provide justification for trust in superiors and influence of superiors as predictors of performance and satisfaction. The data suggest that other factors may account for changes in the research variables.  相似文献
