Reports an error in "Facilitative and disruptive effects of prior exposure to shock on subsequent avoidance performance" by H. Anisman and T. Waller (Journal of Comparative and Physiological Psychology, 1972[Jan], Vol 78[1], 113-122). On page 114, the sentence beginning on Line 56, Column 2, should read: "Thirty seconds after placement in the compartment one half of the rats were given 10 CS (light and tone) presentations in which the CS was 9 sec. in duration, while the remaining rats received 10 CS-US presentations in which the US was a 1-ma. shock (constant current, ac) 2 sec. in duration." (The following abstract of this article originally appeared in record 1972-22565-001.) Subjected 40 male rats from each of 5 strains to 10 signaled inescapable 1-ma shock presentations. Shock facilitated subsequent 1-way and shuttle-avoidance performance (1-ma shock) in Charles River hooded, Wistar, Holtzman, and Sasco Ss, but did not significantly affect avoidance learning in Sprague-Dawley Ss. A 2nd experiment employing 120 male Holtzman rats indicated that inescapable shock of 1 ma. facilitated subsequent 1-way and shuttle-avoidance performance, while exposure to shock of 2 ma. facilitated 1-way and interfered with shuttle-avoidance performance. Movement ratings recorded during both CS and intershock intervals in pretraining were found to be good predictors of subsequent avoidance performance in preshocked Ss. Results are interpreted in terms of response repertoire changes produced by shock in conjunction with the defense reaction necessary in acquiring the avoidance response.

This paper investigates the effects of initial heart-rate level, frustration, and task complexity on digit-symbol performance. Low (LD) and high (HD) heart-rate Ss worked on a digit-symbol problem immediately before and after a frustration manipulation which raised heart rate about 20 beats/min. The results indicated that HD Ss achieved higher initial performance scores than LD Ss on tasks of relatively low complexity; however, following frustration LD Ss manifested a significantly greater increment in performance than HD Ss. The latter group showed a trend toward a decrement in performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

An experiment was conducted to determine the effects of amount of information displayed, level of task difficulty, and practice on performance speed and accuracy for a visual motor task. Based on results from 16 Ss, it was concluded that an increase in the number of cues available for visual reference will not necessarily affect performance. Further cooroborative evidence was obtained for the hypothesis that the criterion of redundancy in displayed information should be based on perceptual usefulness of the cues provided.

Goal orientation and self-regulation theories were integrated to develop a multilevel framework aimed at addressing controversies regarding the magnitude and direction of goal orientation effects on performance. In Study 1, goal orientations were measured repeatedly whilst individuals performed an air traffic control task. In Study 2, goal orientations and exam performance were measured across 3 time points while undergraduates completed a course. Mastery-approach orientation was positively related to performance at the intraindividual level, but not at the interindividual level, and its effect was not moderated by task demands. Performance-approach positively predicted performance at the interindividual level, and at the intraindividual level, the direction of its effect switched as a function of task demands. Performance-avoid negatively predicted performance at the interindividual level but did not emerge as an intraindividual predictor. Mastery-avoid did not relate to performance at either level of analysis. This consistent pattern across 2 studies suggests that levels of analysis and task demands can determine the magnitude and direction of goal orientation effects on performance and highlights avenues for theory development.

Reports an error in the Discussion section of the article "Motivation, Behavior, and Performance: A Closer Examination of Goal Setting and Monetary Incentives," by James R. Terborg and Howard E. Miller (Journal of Applied Psychology, 1978, Vol. 62, No. 1, pp. 29-39). The results of several multiple regressions were incorrectly reported as multiple correlations. In each instance in which the term multiple correlation was used, R2 should have appeared. The sentences in which the error occurred are provided. (The following abstract originally appeared in record 1979-24960-001). Some experimenters often test predictions from theories of motivation using performance outcomes as dependent variables. It is argued that observable behaviors that are likely to be affected by motivation manipulations should be used in combination with performance outcomes. Such procedures would be sensitive to differential effects of manipulations on various behaviors and would allow for investigation of relationships among behaviors and performance outcomes. For this experiment, 60 17-23 yr olds were hired to work individually on a 2-hr construction task. Ss were assigned to 1 of 2 pay conditions (piece-rate vs hourly) and 1 of 3 goal-setting conditions (no goal, quantity, or quality) resulting in a 2 x 3 crossed analysis of variance design. Dependent variables included 3 measures of effort, 3 measures of direction of behavior, and both quantity and quality performance. Method of payment affected quantity performance and effort. Goal setting affected quantity and quality performance and direction of behavior. Implications for designing and testing work motivation systems are discussed.

This paper emphasizes the recognition of the fact that while people tend to maintain a preferred level of arousal or tension, they often expose themselves to new and complex stimulation which seems to have no external reward other than that of yielding new knowledge. This intrinsic interest in novelty and complexity is termed curiosity and can be harnessed to motivate learning to read. Teachers must learn to recognize the preferred level of arousal of each child as well as the level at which he functions most effectively. They must control the irrelevant and distracting properties of the environment in order to gain and maintain the attention of the child. Finally they must become skilled at introducing the learning materials in a manner which will maintain a constant flow of interesting stimulation.

This study examined the relationship of goal orientation and performance over a series of 2 challenging performance events. After providing performance feedback on the 1st event, the authors found that the relationship between a learning goal orientation and performance remained positive for the 2nd event, the relationship between a proving goal orientation and performance diminished from a positive to a nonsignificant level, and the relationship between an avoiding goal orientation and performance remained negative. Data analysis also indicated that the relationships between the 3 goal orientation dimensions and the performance event were differentially mediated by goal setting, self-efficacy, and effort.

The generalizability of temporal parameters of memory formation previously observed for a passive avoidance task was investigated in a spatial task with day-old chicks (Callus gallus). The percentage improvement in completion time over 2 separate trials was measured, and chicks were found to complete the second trial faster at all times tested up to 2 hr, except at 55 min posttraining. In addition, retention at 120 min, but not at 30 min, posttraining was found to be impaired by protein synthesis inhibition. These findings are consistent with the timing of a long-term stage of memory formation following passive avoidance training, implying that there may be some hardwiring to the temporal characteristics of memory formation in this species.

In influential research, R. N. Shepard, C. I. Hovland, and H. M. Jenkins (1961) surveyed humans' categorization abilities using tasks based in rules, exclusive-or (XOR) relations, and exemplar memorization. Humans' performance was poorly predicted by cue-conditioning or stimulus-generalization theories, causing Shepard et al. to describe it in terms of hypothesis selection and rule application that were possibly supported by verbal mediation. The authors of the current article surveyed monkeys' categorization abilities similarly. Monkeys, like humans, found category tasks with a single relevant dimension the easiest and perceptually chaotic tasks requiring exemplar memorization the most difficult. Monkeys, unlike humans, found tasks based in XOR relations very difficult. The authors discuss the character and basis of the species difference in categorization and consider whether monkeys are the generalization-based cognitive system that humans are not.

The authors examine 2 issues: (a) how students integrate information from multiple scientific documents to describe and explain a physical phenomenon that represents a subset of the information in the documents; and (b) the role of 2 sorts of tasks to achieve this type of integration, either writing an essay on a question requiring integration across texts or answering shorter intratext questions that require students to integrate information within a single text, while superficial and deep comprehension measurements are obtained. Undergraduate students answered 1 of the 2 types of questions, and their reading times were recorded. Half of the sample thought aloud. Results showed that the integration question increased integration and decreased the processing of isolated units of information, which enhanced deep learning, whereas no differences between the 2 sorts of tasks on memory recall were apparent. This research also provides evidence for the discrepancy between training and posttraining effects (R. A. Schmidt & R. A. Bjork, 1992).

Experiments to examine the effects of aging on the ability to identify temporal durations in an absolute identification task are reported. In Experiment 1, older adults were worse than younger adults in identifying a tone's position within a series of 6 tones of varied durations. In Experiment 2, participants were required to identify a tone's position in 9 tones of varied durations. Older adults' performance was again worse than that of younger adults; moreover, they showed a qualitatively different pattern of errors than younger adults. In Experiment 3, in which the tones varied in pitch, the performance of older adults was worse than that of younger adults, but the error patterns of the 2 groups were similar. The results suggest that older adults have distorted memory representations for durations but not for pitch. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The dopamine hypothesis of aging suggests that a monotonic dopaminergic decline accounts for many of the changes found in cognitive aging. The authors tested 44 older adults with a probabilistic selection task sensitive to dopaminergic function and designed to assess relative biases to learn more from positive or negative feedback. Previous studies demonstrated that low levels of dopamine lead to avoidance of those choices that lead to negative outcomes, whereas high levels of dopamine result in an increased sensitivity to positive outcomes. In the current study, age had a significant effect on the bias to avoid negative outcomes: Older seniors showed an enhanced tendency to learn from negative compared with positive consequences of their decisions. Younger seniors failed to show this negative learning bias. Moreover, the enhanced probabilistic integration of negative outcomes in older seniors was accompanied by a reduction in trial-to-trial learning from positive outcomes, thought to rely on working memory. These findings are consistent with models positing multiple neural mechanisms that support probabilistic integration and trial-to-trial behavior, which may be differentially impacted by older age.

Reports an error in "Goal neglect and Spearman's g: Competing parts of a complex task" by John Duncan, Alice Parr, Alexandra Woolgar, Russell Thompson, Peter Bright, Sally Cox, Sonia Bishop and Ian Nimmo-Smith (Journal of Experimental Psychology: General, 2008[Feb], Vol 137[1], 131-148). The DOI for the supplemental materials was printed incorrectly. The correct DOI is as follows: http://dx.doi.org/10.1037/0096-3445.137.1.131.supp (The following abstract of the original article appeared in record 2008-01081-009.) In goal neglect, a person ignores some task requirement though being able to describe it. Goal neglect is closely related to general intelligence or C. Spearman's (1904) g (J. Duncan, H. Emslie, P. Williams, R. Johnson, & C. Freer, 1996). The authors tested the role of task complexity in neglect and the hypothesis that different task components in some sense compete for attention. In contrast to many kinds of attentional limits, increasing the real-time demands of one task component does not promote neglect of another. Neither does neglect depend on preparation for different possible events in a block of trials. Instead, the key factor is complexity in the whole body of knowledge specified in task instructions. The authors suggest that as novel activity is constructed, relevant facts, rules, and requirements must be organized into a "task model." As this model increases in complexity, different task components compete for representation, and vulnerable components may be lost. Construction of effective task models is closely linked to g.

The hypothesis tested was that exposure of the infant mouse to shock which could not be terminated by some specific response would lead to greater fearfulness later on than exposure to shock whose termination was contingent on a specific response. 3 groups of mice 8 to 11 days of age were each subjected to different shock conditions. One group could terminate the shock by an avoidance response (response-contingent group), one group had no control over the duration of shock (arbitrary shock group), and the third group received no shock in the apparatus. Later an open-field test of emotionality showed no significant differences, but an adult avoidance learning test showed that the run times of the response-contingent group were significantly shorter than those of the no-shock group.

Reports an error in "The effects of expected group longevity and expected task difficulty on learning and recall: Implications for the development of transactive memory" by Michael R. Baumann and Bryan L. Bonner (Group Dynamics: Theory, Research, and Practice, , , np). An error was introduced during the production process. On article page 8, column 1 line 6 through column 2 line 2, the statement “…the main effect of expected longevity was significant only in the same expertise condition…” is incorrect. The effect found was for expected difficulty, not expected longevity. (The following abstract of the original article appeared in record 2011-09189-001.) The ability to effectively coordinate with others is a vital component of group success. It is often useful to base this coordination on expectations derived from perceived expertise (transactive memory; Wegner, 1986). Yet, the value of coordination overall and specific coordination strategies vary by task. We argue that the benefit of applying a task-appropriate coordination strategy increases with the number of trials of the task performed (expected longevity), and that the most beneficial strategy varies by task difficulty. We, therefore, predict that coordination increases with expected longevity and that the form of coordination (increased or decreased duplication) depends on expected task difficulty. To test these predictions we manipulate expectations of longevity and difficulty among individuals expecting to work with a partner on a memory task. The predicted relationships are found for both learning and recall. The implications of these findings for the development of transactive memory are discussed.

Many findings suggest that changes in circulating estrogen levels influence cognition, in some cases impairing performance and in others enhancing performance. One interpretation of these mixed effects is that estrogen biases the strategy used to solve a task. To test this idea, young adult female rats, ovariectomized for 21 days, were trained after acute hormone or control treatment in 2 very similar tasks with different cognitive requirements. One task required place learning and the other response learning. Rats given two 10-μg injections of estradiol 48 and 24 hr before training learned the place task significantly faster than did rats without estradiol. Conversely, rats without estradiol performed better on the response task than did rats with replacement. These data suggest that the cognitive actions of estrogen may be task-specific by modulating the relative contribution of different learning and memory systems.

The purpose of this study was to examine the viability of knowledge structures as an operationalization of learning in the context of a task that required a high degree of skill. Over the course of 3 days, 86 men participated in 9 training sessions and learned a complex video game. At the end of acquisition, participants' knowledge structures were assessed. After a 4-day nonpractice interval, trainees completed tests of skill retention and skill transfer. Findings indicated that the similarity of trainees' knowledge structures to an expert structure was correlated with skill acquisition and was predictive of skill retention and skill transfer. However, the magnitude of these effects was dependent on the method used to derive the expert referent structure. Moreover, knowledge structures mediated the relationship between general cognitive ability and skill-based performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Five experiments are reported in which standard naming and tempo-naming tasks were used to investigate mechanisms of control over the time course of lexical processing. The time course of processing was manipulated by asking participants to time their responses with an audiovisual metronome. As the tempo of the metronome increased, results showed that (a) the rate of lexical errors increased, whereas the rate of regularization errors remained constant; (b) onset errors increased at a faster rate than body errors; (c) stimulus effects weakened on latencies, whereas they strengthened on durations and errors; and (d) naming durations decreased more slowly when stimuli were presented prior to the response cue. These results constitute evidence that time pressure in the tempo-naming task caused a compression in the time course of lexical processing. Compression is discussed in terms of threshold mechanisms and rate mechanisms of control. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Reports an error in the article, "Toward a Causal Model of Love," by Abraham Tesser and Delroy Paulhus (Journal of Personality & Social Psychology, 1976[Dec], Vol 34[6], 1095-1105). There are six incorrect entries in Table 2 (p. 1101). In addition, on page 1104, left-hand column, the sentence beginning on the 15th line of the paragraph headed Reproducing the Correlations reads: This value was comfortably small, .027 z units. The sentence should be changed to read: This value was comfortably small, .039 z units. Details underlying these corrections are available from the authors.(The following abstract of this article originally appeared in record 1978-31808-001.) Under a proposed systems model of love, (a) thought about other and love for other have a positive causal impact on one another, (b) dating frequency and love have a positive causal impact on one another, and (c) dating has a positive impact on "reality constraints," which, in turn, (d) have a negative impact on love. Questionnaires administered 2 wks apart to a 202-member panel of college students (106 females and 96 males) served as the data collection vehicle. Temporal order of the measures was used to determine causal direction, and path analysis was used to analyze these correlational data. Results support Hypotheses (a), (b), and (d) but do not support Hypothesis (c). (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
