This study investigated the involvement of working memory (WM) in following spoken instructions using concurrent tasks designed to disrupt components of the Baddeley and Hitch WM model [Baddeley, A. D., & Hitch, G. J. (1974). Working memory. In G. H. Bower (Ed.), The psychology of learning and motivation: Advances in research and theory (Vol. 8, pp. 47–89). New York, NY: Academic Press]. In each of three experiments, participants were presented with sequences of instructions to be either verbally repeated or physically performed using relevant objects. Backward counting, articulatory suppression, and eye closure during instruction encoding all disrupted recall, and also impaired recall of the linkage between movements and objects. Recall of actions was more accurate when they were physically enacted than repeated verbally, an advantage that was not affected by concurrent tasks. These findings indicate that aspects of the recall of spoken instructions including the binding of constituent movements to objects draw on multiple WM resources. The benefits of physical enactment of the instructed sequence do not appear to depend on the components of WM investigated in these studies. 相似文献

Most treatments for stereotypy involve arrangements of antecedent or consequent events that are imposed entirely by a therapist. By contrast, results of some studies suggest that self-recording, a common component of self-management interventions, might be an effective and efficient way to reduce stereotypy. Because the procedure typically has included instructions to refrain from stereotypy, self-recording of the absence of stereotypy, and differential reinforcement of accurate recording, it is unclear which element or combination of elements produces reductions in stereotypy. We conducted a component analysis of a self-management intervention and observed that decreases in stereotypy might be attributable to instructional control or to differential reinforcement, but that self-recording per se had little effect on stereotypy. 相似文献

This note discusses the assumption researchers make when movement attributes are precued in a choice reaction time (RT) paradigm—i.e., that the precue only reduces the number of response alternatives, so that changes in RT reflect the programming time for the unprecued attributes. However, it is argued that since the precue reduces the number of stimulus alternatives, changes in RT reflect changes in both stimulus processing and response programming. Therefore, the interpretation made by Klapp (1977), using the precue paradigm, that response selection and response timing are not independent sequential stages in the programming sequence, is not necessarily correct. 相似文献

Self/observer agreement on HEXACO-PI-R scale scores was examined as a function of observers’ subjective ratings of acquaintanceship. For each participant (N = 2199), personality self-reports were obtained along with observer reports from a friend. Each factor-level scale displayed a different pattern of upward accuracy (agreement) trends in personality judgment. Self/observer agreement for Extraversion, Emotionality, and Openness was noticeably stronger at lower acquaintanceship than that for Conscientiousness, Agreeableness, and Honesty-Humility. Conscientiousness showed a steep upward accuracy trend across acquaintanceship levels, reaching a level of accuracy comparable to that of Extraversion and Emotionality. Self/observer agreement for Honesty-Humility and Agreeableness showed slower upward trends than that of Conscientiousness. In several cases, facet-level traits within the same broad factor differed in their accuracy trends. 相似文献

Applying signal-detection theory to the study of observer accuracy and bias in behavioral assessment

We evaluated the feasibility and utility of a laboratory model for examining observer accuracy within the framework of signal-detection theory (SDT). Sixty-one individuals collected data on aggression while viewing videotaped segments of simulated teacher-child interactions. The purpose of Experiment 1 was to determine if brief feedback and contingencies for scoring accurately would bias responding reliably. Experiment 2 focused on one variable (specificity of the operational definition) that we hypothesized might decrease the likelihood of bias. The effects of social consequences and information about expected behavior change were examined in Experiment 3. Results indicated that feedback and contingencies reliably biased responding and that the clarity of the definition only moderately affected this outcome. 相似文献

Instructional effects in creative‐thinking tasks are important to understand in order to promote creative performance of individuals. In divergent‐thinking tasks, for example, instructional and strategic enhancement effects have been extensively studied for verbal tasks. However, while studies on instructional enhancement effects on creative drawing tasks exist, it is surprising that strategy enhancement in figural divergent thinking is still underresearched. In this study, we used a strategy manipulation approach to reassess the role of executive strategy implementation and the moderating role of an indicator of fluid intelligence, figural analogical reasoning, in two types of figural divergent‐thinking tasks (abstract vs. concrete). The sample comprised N = 75 high‐school students. Importantly, we found strategic enhancement effects by combining strategy instructions with a prompt to “be creative.” This combined instruction was contrasted with a standard instruction, and main effects were found for overall, concrete, and abstract creativity. Moreover, we found in a regression analysis a main effect for figural analogical reasoning on overall creativity and creativity for only the concrete object tasks. An expected interaction effect of instruction and figural analogical reasoning was not found. As another addition, the role of current motivation in figural divergent thinking was explored. 相似文献

Although the quality of observational data is generally evaluated by observer agreement, measures of both observer agreement and accuracy were available in the present study. Videotapes with a criterion protocol were coded by 16 observers. All observers calculated agreement scores both on their own and their partner's data and on a contrived data set misrepresented as data collected by other observers. Compared with agreement scores calculated by the experimenter, observers erroneously inflated their own agreement scores and deflated the agreement scores on the contrived data. Half of the observers (n = 8) had been given instructions emphasizing the importance of accuracy during observation while the other half had been given instructions emphasizing interobserver agreement. Accuracy exceeded agreement for the former group, whereas agreement exceeded accuracy for the latter group. The implications are that agreement should be calculated by the experimenter and that the accuracy-agreement relationship can be altered by differential observer instructions. 相似文献

College students' presses on a telegraph key occasionally turned on a light in the presence of which button presses produced points later exchangeable for money. Initially, responding was maintained by low-rate contingencies superimposed on either random-interval or random-ratio schedules. Later, the low-rate contingencies were relaxed. Low-rate key pressing had been established for some students by shaping and for others by demonstration and written instructions. After the low-rate contingencies were relaxed, higher response rates generally did not increase point earnings with random-interval scheduling, but did so with random-ratio scheduling. In both cases, shaped responding usually increased, and instructed responding usually continued at an unchanged low rate. The insensitivity of instructed responding typically occurred despite contact with the contingencies. The differential sensitivity to schedule contingencies of shaped responding relative to instructed responding is consistent with the different properties of contingency-governed and rule-governed behavior and is not rate-dependent. 相似文献

To determine whether ethical issues concerned with field research are addressed in the peer-review process, instructions to
authors and reviewers of 141 (mainly natural science) journals were examined to ascertain how often ethical issues were mentioned.
Only one-third (n=41) of responding journals addressed ethical issues in their instructions to authors or reviewers. When
ethical issues were considered, most of the journals limited their concerns to ethical issues associated with animal and general
human experimentation. No journal mentioned ethical practices in working with indigenous peoples or on traditional lands.
Only two journals addressed the ethics of research in sensitive areas in their instructions to authors, only one in its instructions
to reviewers. We suggest that peer-reviewed journals respond to an emerging issue in ecological research by formally incorporating
research ethics into their instructions to authors and reviewers. Furthermore, these instructions should address the ethical
issues associated with field research and in working with indigenous peoples and on traditional lands. 相似文献

Highly skilled miniature golf players were examined on a simplified miniature golf task under different instructional conditions. Results indicated that requirements to attend to a variety of technical aspects of the game during preparation impaired motor performance, whereas providing players with those aspects of the game they reported thinking of did not affect motor performance. Data on concentration time and perceived difficulty indicated that increasing cognitive demands were associated with a decline in motor precision. The overall pattern of results was interpreted such that attention directed at technical aspects of the game interfered with the players' normal cognitive activity. Susceptibility to interference is a characteristic feature of controlled cognitive operations. Thus, the present results are consistent with the view that conscious cognitive activity may support motor behavior also at late stages of skill development. 相似文献
