以认知风格为依据,将合作学习小组分为场依存同质组、场独立同质组以及异质组。通过小组对开放问题以及逻辑问题的解决,考察不同认知风格个体、不同类型小组的问题解决过程。同时考察问题解决过程对问题解决水平的影响。结果表明:(1)个体在解决不同类型问题时的过程体验不同。(2)问题解决过程在个体的认知风格和逻辑问题解决水平之间起调节作用。(3)不同类型小组的问题解决过程不同。(4)合作是影响小组合作学习效果的重要因素之一。 相似文献

The bandit problem is a dynamic decision-making task that is simply described, well-suited to controlled laboratory study, and representative of a broad class of real-world problems. In bandit problems, people must choose between a set of alternatives, each with different unknown reward rates, to maximize the total reward they receive over a fixed number of trials. A key feature of the task is that it challenges people to balance the exploration of unfamiliar choices with the exploitation of familiar ones. We use a Bayesian model of optimal decision-making on the task, in which how people balance exploration with exploitation depends on their assumptions about the distribution of reward rates. We also use Bayesian model selection measures that assess how well people adhere to an optimal decision process, compared to simpler heuristic decision strategies. Using these models, we make inferences about the decision-making of 451 participants who completed a set of bandit problems, and relate various measures of their performance to other psychological variables, including psychometric assessments of cognitive abilities and personality traits. We find clear evidence of individual differences in the way the participants made decisions on the bandit problems, and some interesting correlations with measures of general intelligence. 相似文献

Raimond Gaita's moral philosophy is distinguished by, among other things, its attention to the role of embodied, enacted witness in disclosing certain moral values, and its understanding of the emotions as forms of thought. In this paper, I consider how Gaita's insights on these matters may be applied to certain questions in the philosophy of religion, paying particular attention to the nature of religious experience and 'the problem of evil'. I suggest that Gaita's discussion of how we come to recognise moral values or 'meanings' can be extended to the question of how we might recognise religious meanings. On this view, religious experience may take the form of an appreciation of the meaning borne by a material context (rather than, for example, some supra-sensory encounter with a supernatural agent), and our sense of the goodness or otherwise of the world may be answerable to the authoritative example of particular lives. 相似文献

We examined the effects of three different presession conditions on tangibly maintained problem behavior for 2 students with autism, using individual-participant multielement designs. First, an analogue functional analysis demonstrated that problem behavior was maintained by access to tangible items. Next, topographies of item rejection were identified. Finally, students were exposed to (a) brief access, (b) no access, and (c) satiation to the tangible items prior to tangible sessions. The results demonstrated high levels of problem behavior following the brief-access and no-access presession conditions and low levels of problem behavior following the satiation condition. The findings are discussed in the context of how satiation might best be defined for these sorts of evaluations. 相似文献

Extinction‐induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when problem behavior recovers during extinction‐based treatments. The current study sought to determine whether resurgence of problem behavior would reliably occur with 5 participants who received treatment with FCT. Results showed that problem behavior reemerged for all but 1 participant when the communicative response was exposed to extinction or thin schedules of reinforcement. These findings suggest that resurgence may account for some instances of response recovery during treatment, and that the described procedure may be useful for the further study of resurgence and eventual prevention of this phenomenon. 相似文献

We examined the effects of teaching overt precurrent behaviors on the current operant of solving multiplication and division word problems. Two students were taught four precurrent behaviors (identification of label, operation, larger numbers, and smaller numbers) in a different order, in the context of a multiple baseline design. After meeting criterion on three of the four precurrent skills, the students demonstrated the current operant of correct problem solutions. These skills generalized to novel problems. Correct current operant responses (solutions that matched answers revealed by coloring over the space with a special marker) maintained the precurrent behaviors in the absence of any other programmed reinforcement. 相似文献

Few direct‐assessment procedures are designed to identify potential negative reinforcers (e.g., including demands in the escape condition of functional analyses). Two participants were systematically exposed to a series of demands nominated by caregivers as potential negative reinforcers. Sessions ended following the first instance of problem behavior, and a hierarchy of demand aversiveness was created based on the latency to the first problem behavior. Subsequent functional analyses confirmed the predictive value of the hierarchy, with shorter latency demands consistently producing more differentiated functional analysis outcomes. 相似文献

In two experiments (n = 264 and 339), I treat brainstorming rules as assigned goals and compare their effectiveness to that of quantity goals as
interventions to improve the number of ideas generated by individuals. Controlling for goal commitment, I find that brainstorming
rules alone do not convey an advantage over even a vague quantity goal presented alone for enhancing the number of ideas generated
in two common tasks. Detailed contrasts revealed that specific, difficult goals were only partially effective on their own,
as expected when goal commitment is moderate. However, I find evidence in both studies that brainstorming rules are useful
adjuncts to specific, difficult quantity goals. Importantly, their combination was the only consistently effective improvement
over both vague quantity goals and brainstorming rules presented alone. I discuss implications for future research adopting
a goal-based view of intervention in idea generation.
