The main issue of this paper concerns the mediating role of risk appraisal in the relation between past and future behavior. We expected previous risky behavior to heighten risk appraisal, which, in turn, should stimulate preventive behavior. Results ofthree tests of this mediation hypothesis showed that past behavior was strongly related to future behavior; people who behaved hazardously in the past indicated that they tend to do so in the future. Generally, the expected relation between past behavior and risk appraisal was supported. More risky behavior in the past was associated with a heightened risk appraisal. Results also indicate a relation between risk appraisal and future behavior, but in the opposite direction as predicted. Heightened risk appraisal was related to increased levels of risk in future behavior. When predicting future behavior by both risk appraisal and past behavior the effect of risk appraisal on future behavior disappeared, while past behavior remained a strong predictor of future behavior. In a few cases risk appraisal still predicted future behavior when past behavior was controlled for. Unfortunately, these cases showed the opposite relation; i.e., heightened risk appraisal was related to more risky future behavior. Implications of these findings for research on the role of risk appraisal will be discussed.  相似文献

We manipulated relative reinforcement for problem behavior and appropriate behavior using differential reinforcement of alternative behavior (DRA) without an extinction component. Seven children with developmental disabilities participated. We manipulated duration (Experiment 1), quality (Experiment 2), delay (Experiment 3), or a combination of each (Experiment 4), such that reinforcement favored appropriate behavior rather than problem behavior even though problem behavior still produced reinforcement. Results of Experiments 1 to 3 showed that behavior was often sensitive to manipulations of duration, quality, and delay in isolation, but the largest and most consistent behavior change was observed when several dimensions of reinforcement were combined to favor appropriate behavior (Experiment 4). Results suggest strategies for reducing problem behavior and increasing appropriate behavior without extinction.  相似文献

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.  相似文献

Utility maximization is widely used to model individuals’ activity scheduling and rescheduling behavior. Utility maximization is based on the assumption that the modeled behavior is the result of a reasoned decision. An alternative to a planned behavior is habitual behavior, whose execution process has become automatic due to its repeated performance. Compared to activity scheduling, little is known about the activity rescheduling behavior. In this paper, we focus our attention on the rescheduling behavior. We step back and ask a basic question: is the activity rescheduling behavior reasoned or habitual? Our initial expectation is that rescheduling behavior is mostly habitual behavior due to its feature of repeated performance. We answer this question by conducting an experiment. Results from the experiment confirm our original null hypothesis that rescheduling behavior is mostly a habitual behavior.  相似文献

The contributions of this symposium on behavior systems are summarized and evaluated by considering two questions: (1) What is a behavior system? (2) What use to the learning theorist are behavior systems? Two examples of behavior systems from the classical ethological literature are compared with the behavior systems discussed in the symposium, and some similarities and differences in the type of analyses used are discussed. Analysis of the pre-organized species-typical behavior systems relevant to the unconditioned stimuli or reinforcers in learning experiments can contribute performance rules and better understanding of the conditions and contents of learning. The organization of behavior systems can also provide important clues to the neural circuitry underlying behavior, and a behavior systems approach can raise novel questions concerning learning and behavioral development. Possible future directions for the behavior systems approach are briefly discussed.  相似文献

In Experiment I, one of three forms of collateral behavior was trained: Differential collateral behavior specific in form to one of two discriminative stimuli; Common collateral behavior of a single form regardless of the stimulus; or Nondifferential collateral behavior of either form regardless of the stimulus. Children were next given a short-delay matching-to-sample task in which the discriminative stimuli served as samples, and the children's previously trained collateral behavior terminated the delay and presented the comparison stimuli. Subjects engaging in sample-specific collateral behavior immediately acquired matching. Subjects engaging in sample-nonspecific collateral behavior failed to acquire matching or did so gradually. In Experiment II the minimal delay in the matching task was varied in a mixed sequence, first with collateral behavior required, and then with collateral behavior prohibited. When emitting collateral behavior Common and Nondifferential subjects showed delay-related decrements in matching while Differential subjects did not. When not emitting collateral behavior all subjects showed delay-related decrements in matching. Common and Nondifferential subjects matched more accurately when prohibited from emitting collateral behavior. Differential subjects matched more accurately when emitting collateral behavior. The results accord with Skinner's (1953, 1968) analysis of precurrent operants.  相似文献

This research examined gender-specific perceptions of risky sexual behavior norms among college students and their relationship with one’s own sexual behavior. We expected that students would misperceive the risky sexual behavior of their peers and that these perceptions would positively relate to their sexual behavior. Undergraduate students from the United States (N?=?687; 57.6% female) completed measures assessing perceived sexual behavior, sexual behavior, and other behaviors (e.g., marijuana use, alcohol consumption). Findings demonstrated that students perceived that others engaged in more risky sexual behavior than they do and that perceived norms were positively associated with one’s own behavior. The incorporation of personalized normative feedback regarding risky sexual behavior into brief interventions aimed at reducing risky sexual behavior is discussed.  相似文献

本研究分别在中国和日本对一岁半到二岁半的婴儿进行自然观察,分析了婴儿之间围绕着某些资源而发生的交涉行为和交换性行为的发生过程及其发展上特点。主要结果有①中日婴儿到2岁左右时开始出现交涉行为和交换性行为,但在该年龄阶段并不占有主导地位。②该年龄阶段婴儿的交换性行为还不能说是完整意义上的交换,属于“前交换行为”。③对于获得对方的东西来说,该年龄阶段婴儿的交涉行为和交换性行为并不是很有效的方式。④我们进行观察的中国幼儿园托儿班的婴儿其交涉行为和交换性行为的出现早于日本保育园的婴儿,但从交涉行为出现的比例来看,日本婴儿采用交涉行为的倾向比中国婴儿更明显。  相似文献

On the basis of the idea that situational norms are mentally represented as associations between environments and normative behavior, it was proposed that an environment can automatically direct normative behavior. More specifically, when situational norms are well-established (e.g., when entering the library, one should be silent), an environment is capable of automatically activating mental representations of normative behavior and the behavior itself. In these experiments, participants were exposed to pictures of environments, and effects on accessibility of representations of normative behavior and on actual behavior were assessed. Results indicated that representations of behavior and actual behavior itself are activated automatically when (a) goals to visit the environment are active and (b) strong associations between environment and normative behavior are established.  相似文献

Investigates the effect of the first-grade classroom environment on the shy behavior, aggressive behavior, and concentration problems of 609 children in 19 East Baltimore public schools. First-grade classroom environment was assessed in terms of dominant pattern of classroom achievement and behavior. Structured teacher ratings assessed child shy behavior, aggressive behavior, and concentration problems at the end of first grade. Children in low-achieving classroom environments had significantly higher teacher ratings of shy behavior and aggressive behavior than children in mixed-achieving or high-achieving environments, even after controlling for potentially confounding child characteristics and classroom behavior environment effects. Analyses controlling for child characteristics and classroom achievement environment effects indicated that children in poor-behaving classroom environments also had significantly higher teacher ratings of shy behavior than children who were not in poor-behaving environments. Subgroup analyses indicated that repeaters in mixed-achieving environments had significantly higher levels of shy behavior compared with nonrepeaters, and repeaters in poor-behaving environments had significantly higher levels of aggressive behavior compared with nonrepeaters. Implications for prevention research are discussed.  相似文献

The unique and interactive contributions of past externalizing behavior, negative parenting, and teacher-child relationship quality to externalizing behavior trajectories after the transition to school were examined. In a sample of 283 children, random regression analyses indicated that conflict in the teacher-child relationship during the school transition contributed to faster rates of increase in externalizing behavior from kindergarten through third grade above and beyond negative parenting and initial levels of externalizing behavior. A significant interaction between teacher-child closeness and the externalizing behavior intercept indicated that decreases in externalizing behavior were associated with teacher-child closeness, especially for children with the highest levels of externalizing behavior upon school entry. Family socioeconomic status and initial levels of classroom externalizing behavior in kindergarten were also significant contributors to the prediction of externalizing behavior trajectories.  相似文献

Differential reinforcement of alternative behavior is a well-established treatment for problem behavior in which the functional reinforcer is delivered after the occurrence of a replacement behavior and withheld after the occurrence of problem behavior. However, sometimes problem behavior continues to occur under these conditions, raising a question as to why problem behavior might maintain when its reinforcer is withheld. This study examined the possibility that problem behavior could be maintained indirectly in a precurrent relation. A functional analysis was conducted to identify a response-response relation between self-injurious behavior (SIB) and an alternative response. The results suggest that SIB was maintained by its relation with the alternative response.  相似文献

Kievit et al.'s target paper exemplifies a trend in recent years in psychology and neuroscience to focus on internal mental and neural processes without integrating actual behavior. We discuss the theoretical status of behavior in the context of their model, and present an extension of the model that explicitly includes behavior. Several theoretical and methodological issues relevant to integrating behavior into the model are considered, particularly the distinction between behavior as measured in the laboratory along with neural and psychological processes (proximal behavior) and behavior as measured in situ as part of ongoing daily experience (distal behavior). We conclude by describing several studies that integrate neural, psychological, and behavioral indicators and discuss how these kinds of studies can facilitate a better understanding of behavior and contribute to theory development.  相似文献
