在人工语法范式、序列反应时任务范式以及复杂系统控制任务范式中,内隐学习对学习材料的难度及复杂度、材料性质、材料呈现方式等较为敏感。具体表现为难度和复杂程度较高的学习材料,以及形象性较突出的学习材料,更适合内隐学习,而使材料结构特点变得明显的呈现方式不利于内隐学习。然而,内隐学习的材料敏感性在其它范式上的普遍性有待进一步的实验研究。 相似文献

This study evaluated whether a concurrent group teaching procedure, in which all students respond simultaneously, could be used for persons with moderate or severe mental retardation. The teaching procedure used was the Task Demonstration Model, a program based on stimulus-control research and the fading techniques of behavioral psychology. Three teachers and three groups of students participated. Results showed that the teachers increased their rates of questions and instructions, positive feedback, and use of functional materials, but they reduced their rate of prompts to almost zero. Students increased their percentage and rate of correct responding as well as their engaged time. In addition, maladaptive responding, for which there were never any direct consequences, decreased from 45% to 10% for 8 of the 14 students. Results are discussed primarily in two areas: (a) changing stimulus control from teacher prompts to critical elements of the items being taught, and (b) reasons for the reduction of maladaptive behavior for 8 of the subjects. 相似文献

College students were exposed to a control mathematics assignment containing 16 three-digit by two-digit multiplication (3×2) problems and two experimental assignments that contained 16 equivalent 3×2 problems and six additional interspersed problems. On one experimental assignment, 4-digit plus 4-digit problems (4+4) were interspersed. On the other experimental assignment, 2-digit divided by 1-digit with whole number answers problems (2/1) were interspersed. When given a choice, significantly more students choose the 2/1 assignment over the control and 1+4 assignment. Students also ranked the 2/1 sheet as requiring less time to complete than the control or 4+4 assignment but no differences were found on assignment difficulty rankings between the 4+4 and 2/1 assignments. No differences were found on accuracy levels or rates of responding on the target 3×2 problems across assignments. Results showed that interspersing additional problems that take relatively less time to complete may be more important for altering student preference for assignments than interspersing easier problems. Discussion focuses on schedules of reinforcement and resource efficient procedures for increasing student preference for assignment without compromising curricula integrity. 相似文献

Students with learning difficulties participated in two studies that analyzed the effects of problem difficulty and reinforcer quality upon time allocated to two sets of arithmetic problems reinforced according to a concurrent variable-interval 30-s variable-interval 120-s schedule. In Study 1, high- and low-difficulty arithmetic problems were systematically combined with rich and lean concurrent schedules (nickels used as reinforcers) across conditions using a single-subject design. The pairing of the high-difficulty problems with the richer schedule failed to offset time allocated to that alternative. Study 2 investigated the interactive effects of problem difficulty and reinforcer quality (nickels vs. program money) upon time allocation to arithmetic problems maintained by the concurrent schedules of reinforcement. Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative. The magnitude of this effect was greatest when combined with the low-difficulty problems. These studies have important implications for a matching law analysis of asymmetrical reinforcement variables that influence time allocation. 相似文献

Both the elements and the eigenvalues of the Pearson correlation matrix of dichotomous Guttman-scalable items can be expressed as simple functions of the number of items if the score distribution is uniform and there is an equal number of items at each difficulty level. Even when these special conditions do not hold, the correlations can often be expressed in a simple form by assuming a particular score distribution.The author thanks Neil Dorans, Bob Mislevy, Ledyard R Tucker, and Howard Wainer for their comments. 相似文献

In contrast to the motive literature, motivational intensity theory predicts that the implicit achievement motive (nAch) should only exert an indirect impact on effort by limiting the impact of task difficulty. To contrast these two views, sixty-eight participants with a low or high nAch performed an easy or difficult arithmetic task. Effort was assessed using cardiac pre-ejection period (PEP). Supporting motivational intensity theory’s view, PEP response was low in both easy-task conditions but stronger in the high-nAch group than in the low-nAch group in the difficult task. These findings suggest that nAch exerts an indirect effect on effort investment by setting the maximally justified effort instead of directly determining the amount of effort that is invested to satisfy the motive. 相似文献

‘Range anxiety’ is considered a barrier to market acceptance of electric vehicles (EVs), but perceptions of inadequate recharging infrastructure and limited battery range may be part of a more complex set of consumer concerns; experiences and practices of existing EV drivers – with reference to wider transport and energy systems – need to be understood in greater detail. Qualitative material from semi-structured interviews [n = 88] is used to formulate a chronological Typology of Electric Vehicle Driving which synthesises drivers’ decisions, actions and dynamic considerations before, during and after a journey. The typology outlines and tabulates spatio-temporal elements specific to driving an EV; describes adaptations and compromises in household routines and travel habits; draws out how or when drivers engage with external digital information sources – i.e. smartphone apps, social media – during journey-making; plots their intervention in behavioural changes; and could inform development of infrastructure, tools or services, policy or interventions to support EV uptake. 相似文献

选取山东省某初中308名学生,采用爱荷华博弈任务,使用“效用-固着”模型对决策包含的动机、认知、反应心理过程进行认知建模分析,探究自尊水平和性别对初中生风险决策表现的影响。结果发现,初中生的风险决策表现不佳,对损失不敏感。在控制年级的影响后,分层回归分析表明:(1)自尊水平和性别对决策的动机过程的影响存在交互作用,男生无论自尊高低对收益都较为关注,女生中高自尊者更加关注收益。(2)决策成绩不存在显著的性别差异,但男生更多选择有着较高损失值的不利选项,而女生更多选择损失频率较低的有利选项。(3)自尊的影响主要体现在动机和认知过程,高自尊水平者在动机过程中更多表现出对损失的规避,在认知过程中更多地考虑维持之前的决策选择。 相似文献

The coding of stimuli and responses is crucial for human behaviour. Here, we focused primarily on the response codes (or response categories). As a method, we applied a combined dual-task and task-switch paradigm with a fixed task-to-hand mapping. Usually, negative effects (i.e., costs) are observed for response category repetitions under task switching. However, in several previous studies it has been proposed that such repetition effects do not occur, if the stimulus categories (e.g., “odd” if digits have to be classified according to their parity feature) are unequivocally mapped to specific responses. Our aim was to test this hypothesis. In the present experiments, we were able to distinguish between three different types of possible response codes. The results show that the participants generally code their responses according to abstract response features (left/right, or index/middle finger). Moreover, the spatial codes were preferred over the finger-type codes even if the instructions stressed the latter. This preference, though, seemed to result from a stimulus–response feature overlap, so that the spatial response categories were primed by the respective stimulus features. If there was no such overlap, the instructions determined which type of response code was involved in response selection and inhibition. 相似文献
