The development of position and stimulus biases often occurs during initial training on matching-to-sample tasks. Furthermore, without intervention, these biases can be maintained via intermittent reinforcement provided by matching-to-sample contingencies. The present study evaluated the effectiveness of a correction procedure designed to eliminate both position and stimulus biases. Following key-peck training, a group of 6 pigeons had extended exposure to matching-to-sample contingencies without a correction procedure, a group of 4 pigeons was briefly exposed to a simultaneous matching-to-sample procedure to assess biases prior to exposure to the correction procedure, and a group of 5 pigeons was exposed directly to the correction procedure. The correction procedure arranged that every time an incorrect match was made, the trial configuration was repeated on the subsequent trial until a correct match was made. Extended exposure to matching-to-sample contingencies without a correction procedure was associated with reduced biases eventually for most subjects, but rapid development of near-perfect accuracy and bias-free performance was observed upon the implementation of the correction procedure regardless of the type of bias. Bias-free performance was maintained following subsequent exposure to a zero-delay MTS procedure.  相似文献

This experiment was conducted to investigate the effects of quality-contingent pay systems on quantity and quality. Three computer science students were paid to create simple computer programs across 25 sessions. A multiple-baseline across subjects design was used to compare the effects of three kinds of pay systems; pay-for-hour, pay-for-quantity, and pay-for-quality systems. The quantity was higher when pay was based on the quantity of the programs produced, and the quality was highest when pay was based on the quality of the programs. The production cost including quality inspection costs was highest when pay was based on the time worked.  相似文献

A discrete-trials, delayed-pair-comparison procedure was developed to study visual short-term memory for tilted lines. In four experiments, pigeons' responses on left or right keys were reinforced with food depending on whether a comparison stimulus was or was not the same as a standard stimulus presented earlier in the same trial. In Experimental I, recall was an increasing function of the exposure time of the to-be-remembered stimulus and was a decreasing function of the retention interval. In Experiment II, retroactive interference was investigated: recall was poorer after a retention interval during which was presented either a tilted line or contextual stimuli in the form of the illuminated experimental chamber. In Experiment III, a subject was required to engage, throughout the retention interval, in one or the other of two different behaviors, depending on which of two stimuli a subject was to remember. This mnemonic strategy vastly improved recall after 15- and 20-second retention intervals. In Experiment IV, the opposite end of the performance continuum was studied: by combining the effects of a larger stimulus set and the effects of what presumably was an increased memory load, performance was reduced to approximately chance levels after retention intervals shorter than 1 second.  相似文献

研究以Ellsberg选瓶任务为决策材料,探讨了不同任务特征下个体不确定性容忍度对模糊决策中决策偏好的影响。结果发现,获益情景下:高概率时高、低容忍度个体对模糊选项的选择无显著差异,均偏好模糊规避;中概率时低容忍度个体比高容忍度个体表现出更低程度的模糊规避,前者倾向于模糊中立,后者倾向于模糊规避;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊中立。损失情景下:高概率时两者对模糊选项的选择无显著差异,均倾向于模糊寻求;中概率时低容忍度比高容忍度个体更偏好模糊寻求,前者倾向于模糊寻求,后者倾向于模糊中立;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊规避。这表明,不确定性容忍度对模糊决策偏好产生作用,但这种作用会受到损益概率和损益结果的影响,具有情景依赖性。  相似文献

The Santa Clara Strength of Religious Faith Questionnaire (SCSORF) was administered to 124 undergraduate college students attending a private Catholic university and the result was compared to measures of spirituality, religious behavior, religious coping, and affect. The present study found that the SCSORF was strongly related to spirituality, in particular, seeking support from one's spirituality. However, the SCSORF was not correlated with an openness to new spiritual experiences. The SCSORF was also related to religious behavior and religious coping. The SCSORF was not related to affect, indicating that scores on the SCSORF were not affect-dependent. Results from this study provide additional evidence that the SCSORF is a reliable and valid measure of religious faith.  相似文献

通过两个实验,探讨空间工作记忆负载对中央注视线索引发返回抑制(inhibition of return,IOR)的影响。实验一通过再认面孔的相似度来控制与中央注视线索相关的空间工作记忆任务负载,结果发现,高任务负载条件下出现IOR,低任务负载条件下中央注视线索促进搜索;实验二在实验一高任务负载的基础上加入与注视线索无关的空间工作记忆任务,结果发现,仅在与注视线索无关的空间工作记忆负载低的条件下出现IOR。结果表明,中央注视线索引发的IOR受到空间工作记忆资源的限制,中央注视线索只有在获得足够的资源时才能引发IOR。注视线索获得空间工作记忆资源多少决定中央注视线索能否引发IOR。  相似文献

Rats were trained on a discrete-trial procedure in which one alternative (VR) was correlated with a constant probability of reinforcement while the other was correlated with a VI schedule which ran during the intertrial intervals and held the scheduled reinforcer until they were obtained by the next VI response. Relative reinforcement rate was varied in series of conditions in which the VR schedule was varied and in series in which the VI was varied. Choice behavior was described well by the generalized matching law, although moderate undermatching occurred for all subjects. Contrary to the predictions of molar maximizing (optimality) theories, there was no consistent bias in favor of the ratio alternative, and the sensitivity to reinforcement allocation was not systematically affected by whether the ratio or interval schedule was varied. The results were also contrary to momentary maximizing accounts, as there was no correspondence between the probability of a changeover to the VI behavior and the time since the last response to the VI alternative. Neither variety of maximizing theory appears to provide a general explanation of matching in concurrent schedules.  相似文献

The aim of the current study was to explore how the location updating effect is affected when people are tested using recall rather than recognition, which is what has been done in prior work. Differences in the memory processes involved with these two tasks lead to predictions for two different patterns of data. In Experiment 1, memory was tested by having participants recall the single object they were carrying or had just put down, whereas in Experiment 2, people sometimes needed to recall both objects. It was found that, unlike recognition test performance, a similar location updating effect was found for both Associated (what was currently being carried) and Dissociated (what was recently set down) objects. Moreover, when both objects were correctly recalled, there was a bias to remember them in the order that they were encountered. Finally, if only one object was correctly recalled, it was the Associated object that was currently being carried. Overall, these results are consistent with the Event Horizon Model of event cognition.  相似文献

The effect on cognitive performance of attending to internally generated stimuli was examined. Specifically, the effect of examining feelings and sensations upon performance in the Stroop test and upon the performance of mental addition was measured. In two initial experiments subjects more quickly named, in the Stroop test, the color of the ink (“red”) in which a color word (“green”) was printed following instructions to attend to their feelings. It was found that this facilitation was due in part to the slowing of the automatic, interfering habit of reading for word meanings. In a third experiment, the effect of attending to physical sensations on the back of the hand was found to have a similar facilitating effect and was seen as resulting from the allocation of attention to internally generated stimuli. In a final experiment, attending to feelings and to the physical sensations on the back of the hand was found to increase speed of mental addition. This effect was attributed to increased attention to internally generated stimuli (here knowledge about the arithmetic performance at the moment).  相似文献

Piaget attributes perseverative error in infant manual search to the failure of the infant to conceive of objects as permanent entities which retain their identity when hidden at successive locations A and B. An experiment was performed to test this explanation in which search was compared under three conditions: when the object was hidden at A and B, when the object was covered but visible at A and B, and when the object was visible and uncovered at A and B. Errors occurred under all three conditions taking the form of a conflict in which infants searched persistently either at A or at B. The conflict was at a maximum when the object was hidden, but was evident even when the object was visible but covered. It is suggested that errors may reflect lack of coordination between egocentric and visual frames of reference in relation to which the object is located.  相似文献

We hypothesized individual differences in the tendency to attend to, think about, and focus on positive (or negative) information. A scale measuring these individual differences was constructed and its validity and reliability were examined in three studies. Attention to positive information was related to positive affectivity, extraversion, BAS, optimism. Attention to negative information was related to negative affectivity, neuroticism, BIS, and optimism (inversely). Validity was partially confirmed by a person perception task: individuals high in attention to positive information perceived the character in a story as happy. Attention to positive information was a partial mediator of the relation between extraversion and positive affect and attention to negative information was a partial mediator of the relation between neuroticism and negative affect.  相似文献

We conducted an investigation to evaluate the effects of a training strategy for teaching autistic students generalized responses to three forms of wh— questions (what, how, and why). Students were taught, using modeling and reinforcement procedures, to answer questions with magazine pictures as the referents. Each question form was divided into two or more subcomponents reflective of common social usage and was taught within the context of a modified multiple probe design across subcomponents. Following acquisition of each subcomponent, generalization to natural context and storybook questions was assessed; additional probes were conducted to assess responding over time and whether acquisition of responses to questions promoted question-asking skills. Results showed that the picture training procedure was effective in teaching a generalized response to questions for which the relevant cue was visible, whereas specific generalization programming was required for situations in which the relevant cue was not visible. All acquired responses were durable over time.  相似文献

采用移动窗口阅读技术和探测技术探讨大学生中文阅读过程中对因果与转折关系的理解差异。实验一在句子层面考察因果和转折关系的理解差异,结果发现被试阅读转折句的时间显著长于因果句,但对两种句子中探测词的反应时没有差异。实验二运用探测技术从篇章层面进一步探讨两种关系的理解差异。结果发现,转折关系条件下被试对探测词的反应时显著慢于因果关系条件下。实验结果表明,无论在句子层面还是在篇章层面,被试对转折关系的表征都难于因果关系的表征。  相似文献

Using a national, random sample (N=2130), we investigated the relationship between each of the Big Five personality traits and conflict and facilitation between work and family roles. Extraversion was related to greater facilitation between roles but was not related to conflict, whereas neuroticism was related to greater conflict but only weakly related to facilitation. Conscientiousness was related to less conflict, presumably reflecting efficient time use and organizational skills. In general, conflict was negatively related to work-family outcomes (e.g., lower job and family effort and satisfaction) whereas facilitation was positively related to the same outcomes. Conflict and facilitation were shown, however, to be orthogonal rather than opposite constructs. Implications for work-family theory, for the understanding of personality traits, and for enhanced responsibilities of organizations are discussed.  相似文献

According to Regulatory Focus theory (RFT), outcomes in persuasive messages can be framed in four different ways, as gains, non-gains, losses or non-losses. In study 1, the persuasiveness of all four frames was compared and the presence/absence effect that was expected on the basis of the feature-positive effect was verified: Statements about present outcomes (gain, loss) were more persuasive than those about absent outcomes (non-gain, non-loss). However, this study failed to support the prediction that a gain-framed message would be more persuasive than a loss-framed message when promoting a prevention behaviour. Study 2 was designed to examine the latter finding. It was hypothesised that the threat posed by the loss-framed message in study 1 was too low to elicit a defensive reaction. Therefore, in study 2, the personal relevance of the gain and the loss framed message was manipulated. Consistent with predictions, the gain-framed message was more persuasive than the loss-framed message, but only when the message was personalised to increase self-relevance. Moreover, the effect was due to a significant drop in persuasion in the loss condition, probably caused by a defensive reaction. These data shed a new light on the findings of past framing studies.  相似文献
