该研究使用RJR研究范式,探讨内隐的可接近信息对FOK判断等级和判断准确性的影响。结果发现:FOK判断等级受内隐的可接近信息量的影响,二者呈非单调递增、递减的关系;FOK判断等级随内隐的可接近信息强度的增强而增高;FOK判断准确性随内隐的可接近信息量的增多而降低,并随内隐的可接近信息强度的增强而增高。 相似文献

Mediation is a process that links a predictor and a criterion via a mediator variable. Mediation can be full or partial. This well-established definition operates at the level of variables even if they are categorical. In this article, two new approaches to the analysis of mediation are proposed. Both of these approaches focus on the analysis of categorical variables. The first involves mediation analysis at the level of configurations instead of variables. Thus, mediation can be incorporated into the arsenal of methods of analysis for person-oriented research. Second, it is proposed that Configural Frequency Analysis (CFA) can be used for both exploration and confirmation of mediation relationships among categorical variables. The implications of using CFA are first that mediation hypotheses can be tested at the level of individual configurations instead of variables. Second, this approach leaves the door open for different types of mediation processes to exist within the same set. Using a data example, it is illustrated that aggregate-level analysis can overlook mediation processes that operate at the level of individual configurations. 相似文献

本研究采用眼动追踪技术,通过对预期性和词频、预期性和笔画数在词汇识别过程中是否存在交互作用进行考察,以探讨预期性效应对词汇识别产生影响的加工阶段。结果显示,预期性和词频、预期性和笔画数之间均不存在交互作用。由此表明,预期性、词频和笔画数均独立地对中文文本阅读中的词汇识别产生显著的影响,该结果符合E-Z读者模型的研究假设。 相似文献

Delayed signal detection, differential reinforcement, and short-term memory in the pigeon. 总被引:6,自引:6,他引:0 下载免费PDF全文
In two discrete-trial delayed-detection experiments, six pigeons were trained on dependent concurrent variable-interval schedules. Pecking a red side key was reinforced when the brighter of two white lights (S1) had been presented on the center key, and pecking a green side key was reinforced when the duller of two white lights (S2) had been presented on the center key. Incorrect responses were red side-key pecks following S2 presentations and green side-key pecks following S1 presentations; these resulted in three-second blackouts. In Experiment 1, the time between presentation of S1 or S2 on the center key and the onset of the red and green side keys was varied nonsystematically from 0.06 seconds to 19.69 seconds across experimental conditions. Stimulus discriminability decreased as the stimulus-choice delay increased. A rectangular-hyperbolic function better described this decrease in discriminability over time than did a negative-exponential function. In Experiment 2, at each of three stimulus-choice delays (0.06, 3.85, and 10.36 seconds), relative reinforcer frequency for correct responses to the red and green side keys was varied by changing the values of the dependent concurrent variable-interval schedules. The sensitivity of choice to relative reinforcer frequency was independent of the decrease in stimulus discriminability with increasing stimulus-choice delay. 相似文献

Frequency versus magnitude of reinforcement: New data with a different procedure 总被引:4,自引:4,他引:0 下载免费PDF全文

Two pigeons, with previous exposure to concurrent schedules, were submitted to 29 sessions of 8 hours each with concurrent variable-interval variable-interval schedules in which reinforcement parameters changed from session to session. In the first nine sessions reinforcement durations were equal in both schedules while reinforcement frequencies varied; in Sessions 10 through 18, both frequency and duration of reinforcement were varied; in Sessions 19 through 29, only reinforcement duration was varied. Results with this different procedure confirm previous findings that behavior is more sensitive to changes in reinforcement frequency than to reinforcement magnitude. 相似文献

Discriminability of frequency of food or stimulus presentations in variable-time schedules 下载免费PDF全文

Pigeons responded in a two-alternative forced-choice task in which reinforcement was dependent upon the frequency of events that occurred in an immediately preceding schedule sample. On a given trial the events were either brief food presentations or brief visual and auditory stimulus changes. High levels of stimulus control were obtained by food-presentation schedules only. Discriminative control by frequency or stimulus change was absent. Stimulus control by food frequency was decreased by the imposition of a delay period between the schedule sample and the choice. Moreover, stimulus control by food frequency was related to the ratio of food-presentation schedule pairs when novel schedules were presented in a transfer test. 相似文献

The effect of a municipal enforcement program to improve residents' packaging of refuse was analyzed in a multiple-baseline design across two areas of a city. The enforcement program involved instruction concerning refuse-packaging regulations, collection only of appropriately packaged refuse, and feedback notices to residents concerning the reasons for noncollection of their inadequately packaged refuse. Both the number of violations and the percentage of residences violating each day were markedly reduced during the enforcement program. Furthermore, sanitation workers considered that the packaging of refuse and the safety and efficiency of refuse collection had improved. This study served as a pilot evaluation of a policy change in the city sanitation department, and was functional in determining the direction of that policy. 相似文献

A community education system might be most effectively implemented in low-income communities if it were deliverable by neighborhood residents. A proctor training manual, designed to teach neighborhood residents how to administer standardized learning units to their peers, was analyzed in two experiments. The results of Experiment I showed that the percentage of occurrence of proctor behaviors increased after completion of the manual. Supplementary data suggest that specified proctor behaviors generalize to actual instructional situations. The results of Experiment II showed that the percentage of occurrence of trainee behaviors was higher when instructional packages were administered by trained proctors than when administered by untrained proctors. This study demonstrates an effective procedure for training low-income community residents to serve as proctors for a community education system. 相似文献

Three female human subjects pressed a button for monetary reinforcement in a range of variable-interval schedules specifying different frequencies of reinforcement. On alternate days, responding was also punished (by subtracting money) according to a variable-ratio 34 schedule. In the absence of punishment, rate of responding was an increasing negatively accelerated function of reinforcement frequency; the relationship between response rate and reinforcement frequency conformed to Herrnstein's equation. The effect of the punishment schedule was to suppress responding at all frequencies of reinforcement. This was reflected in a change in the values of both constants in Herrnstein's equation: the value of the theoretical maximum response-rate parameter was reduced, while the parameter describing the reinforcement frequency corresponding to the half-maximal response rate was increased. 相似文献
