One-hundred-and-sixty adolescents participated in two studies designed to investigate the relationship between IE and helping behavior as mediated by the perceived cause of another's need. In the first study, Ss were given the opportunity to help, either “indirectly” or “directly,” a supervisor who had been over- or underpaid in a prior similar task. Internals helped more in the “direct” help than the “indirect” help conditions but their helping behavior and their perceptions of their supervisors were not consistent. The perceptions of the externals were relatively consistent with their greater help of the “overpaid” supervisor. In study 2, the Ss were given additional information to increase the possibility of their making causal attributions as a function of the supervisor's prior fate. Once again, the external subjects' helping behavior reflected their perception of their supervisor's merit. The internal subjects exhibited relatively little helping behavior regardless of their supervisors' prior fate or perceived competence.  相似文献

The effects of age, modeling, tuition, and sanctions on self-control of motor behavior were examined. Children 6, 7, 9, and 11 years of age individually participated. A male model either: (a) instructed and performed “Simon Says” in the traditional manner, (b) introduced the sanction “Don't” on the inhibition trials, (c) performed an action that differed from the instruction, or (d) gave instructions only. Activation latency and inhibition error were influenced most greatly by the actions of the model and the introduction of a negative sanction, whereas tuition was less effective. Age differences were present for inhibition errors as well as activation latency and error. The discussion focused on the differential effects of modeling and tuition on deviant responding.  相似文献

The functional equivalence of problem solving skills   总被引:1,自引:0,他引:1  
The tower of Hanoi problem is used to show that, even in simple problem environments, numerous distinct solution strategies are available, and different subjects may learn different strategies. Four major classes of solution strategies are described for the problem. Different strategies have different degrees of transferability, place different burdens on short-term memory and on perception, and require different learning processes for their acquisition. The analysis underscores the importance of subject-by-subject analysis of “what is learned” in understanding human behavior in problem-solving situations, and provides a technique for describing subjects' task performance programs in detail.  相似文献

Simple motor reaction times (right-handed) to tape-recorded consonant-vowel syllables were obtained from 12 subjects under two conditions of monotic stimulation: “expected” presentation (subject informed as to ear of presentation) and “random” presentation (ear of presentation varied randomly). Significantly faster left ear reaction times were obtained in the “expected” condition. The rank order of subjects' standard dichotic listening task scores correlated negatively with reaction time ear differences in the “expected” presentation condition. Results are discussed in terms of existing theories of response lateralization in simple reaction time tasks, and an expanded hypothesis is offered. Specifically, it is suggested that two or more distinct but potentially overlapping mechanisms may be responsible for observed asymmetries in monotic auditory perception. Both an attentional or lateralized motor response bias and an inherent lateralization of function may operate side by side, differentially activated by task demands, mode of stimulus presentation, and nature of stimuli.  相似文献

After being instructed either to “empathize with the actor” or to “picture the events clearly,” two groups of observers read a story describing an actor's behavior, and then gave free-response explanations of that behavior, and rated the importance of personal and situational causal factors. The hypothesis that causal attributions of empathizing observers would be less personal and more situational than those of nonempathizing observers received strong support, both from subjects' free responses and from their scale ratings. These findings provide evidence for an information-processing explanation of actor/observer attributional differences. Some practical applications of increasing the situationality of observers' causal attributions are discussed. The results also suggest a novel operational definition of “empathy”; and are interpreted as evidence for the effectiveness of “interpersonal simulations”.  相似文献

Phonological processing was investigated in nine Broca's aphasics. A receptive phonological task examined knowledge of phonotactic rules. Three lists of “word” pairs, phoneme sequences, were constructed such that one member was possible in English and the other was not. The lists varied in distance from English or phonemic structure (CCVC vs. CCVCC). Following auditory presentation, the aphasic was required to indicate which of the two “words” was possible in English. The productive task was an articulation test for monosyllabic and polysyllabic words. The high positive correlation between receptive and productive scores suggested that, rather than motor speech sequencing problems being exclusively involved, more general phonological-articulatory processes were disrupted. Several hypotheses were advanced to describe the nature of this disruption.  相似文献

Two reinforcement schedules were used to compare the predictive validity of a linear change model with a functional learning model. In one schedule, termed “convergent,” the linear change model predicts convergence to the optimum response, while in the other, termed “divergent,” this model predicts that a subject's response will not converge. The functional learning model predicts convergence in both cases. Another factor that was varied was presence or absence of random error or “noise” in the relationship between response and outcome. In the “noiseless” condition, in which no noise is added, a subject could discover the optimum response by chance, so that some subjects could appear to have converged fortuitously. In the “noisy” conditions such chance apparent convergence could not occur.The results did not unequivocally favor either model. While the linear change model's prediction of nonconvergence in the divergent conditions (particularly the “noisy” divergent condition) was not sustained, there was a clear difference in speed of convergence, counter to the prediction inferred from the functional learning model. Evidence that at least some subjects were utilizing a functional learning strategy was adduced from the fact that subjects were able to “map out” the relation between response and outcome quite accurately in a follow-up task. Almost all subjects in the “noisy” conditions had evidently “learned” a strong linear relation, with slope closely matching the veridical one.The data were consistent with a hybrid model assuming a “hierarchy of cognitive strategies” in which more complex strategies (e.g., functional learning) are utilized only when the simpler ones (e.g., a linear change strategy) fail to solve the problem.  相似文献

Many investigators have demonstrated that task-contingent extrinsic incentives can reduce an individual's interest in some intrinsically rewarding task. Although it has been widely assumed that this “undermining effect” is mediated by the individual's causal attributions for engaging in the task, there has been little independent verification of this notion. In the present study subjects were asked to perform an inherently interesting problem-solving task. Half of the subjects were told that they could earn money by solving the task successfully (Money condition), whereas the other half were not (Control condition). Consistent with previous research, Money condition subjects expressed less liking for the task. In addition, Many condition participants attributed their task performance to less internal causes. Furthermore, across conditions, subjects who attributed their behavior to less internal causes were less apt to enjoy the task. The present data, therefore, more convincingly implicate the mediating role of causal attributions in the relationship between extrinsic rewards and intrinsic interest. Alternative explanations are discussed.  相似文献

A point by point examination of Trabasso and Foellinger's paper shows their criticisms of my 1970 work to be based on errors of fact (regarding the data I reported) and errors of method (regarding proper procedures for model evaluation). Factual errors are refuted by summarizing crucial data reported in 1970 but ignored by my critics. Errors of method are refuted by contrasting my CSVIBE model and data with Trabasso and Foellinger's model and data in the light of the scientific epistemology of model evaluation. The issues of “general” versus “local” models, their “empirical scope,” “number of empirical parameters,” and “simplifying assumptions” are examined. Five ways of evaluating models are distinguished, and in all five my 1970 model is shown to be superior to that of Trabasso and Foellinger. The 1970 data (in light of the controls built into the CSVI task) and new unreported data exhibiting developmental step functions confirm the model of a developmental growth of M (mental energy, working memory), which occurs concurrently with and independently from the growth of executive/control structures. Executive growth alone cannot explain the obtained results.  相似文献

Burbeck & Luce (Perception & Psychophysics, 1982, 32 (2), 117–133) argue that their simple reaction time data is best accounted for by the parallel operation of a change and a level detector. Here a specific example of such a compound model is tested. The primary focus is on the change detector which is modeled after a post inhibitory rebound (PIR) neuron. PIR neurons are plausible candidates for the “off” units found throughout the auditory system. The level detector is assumed to be a simple leaky integrator. Computer simulations of the compound model are compared to simple reaction time data. The results, although not without some deficiencies, support the model.  相似文献

Three experiments are reported that explore 3-year-olds' and adults' understanding of the words, same and different. In the first, 3-year-olds selected a bead that was “the same color as” or “a different color from” a target bead. In the second, 3-year-olds selected a bead that was “the same in some way as” or “different in some way from” a target bead. Contrary to results reported previously, the majority of consistent responders chose a bead identical with the target in response to the different instruction in both experiments. The rates of both incorrect different responding and incorrect same responding were greater in Experiment II than in Experiment I. In Experiment III, adults chose objects that were “the same as” or “different from” a target; unlike the children, they never chose a target-identical object in response to different instructions. It is argued that children and adults treat same and different differently, and that children's task performance is influenced by three factors: semantic, pragmatic, and nonlinguistic.  相似文献

This study analyzed the strategies that children ages 5 through 8 years used on two modified versions of Inhelder and Piaget's (The early growth of logic in the child. New York: Norton, 1964) class inclusion task. In two experiments, children were tested on Wilkinson's (Cognitive Psychology, 1976, 8, 64–85) “percept” inclusion task in which distinctive features marked both supraordinate and subclasses. It was hypothesized that children who fail standard Piagetian inclusion tasks succeed on the “percept” task by counting and comparing mutually exclusive features rather than using features as markers for classes and subclasses. The hypothesis was supported by children's performances on “percept” tasks in which solutions based on feature counting conflicted with solutions based on consideration of class inclusion relations. In two other experiments, children answered part-whole and part-part comparison questions in which both terms were described as classes and/or subclasses, or in which one of the two terms was described as a collection (e.g., a bunch of grapes). These experiments contrasted Markman and Seibert's (Cognitive Psychology, 1976, 8, 561–577) “organization” hypothesis that the greater psychological integrity of collections facilitates reasoning on part-whole comparison problems with the hypothesis that the faciltative effect results from the “large number” connotation of collective nouns. Results on collection problems in which parts were described as collections supported the “large number” hypothesis. Results were discussed in terms of their implications for Piaget's theory.  相似文献

Male college students were given the opportunity to deliver aversive noise to a partner (confederate) contingent on the partner's “mistakes” in a learning task. Subjects were either not informed about a reward or told that they, their partner, or a charity would receive a monetary reward for speedy learning. Half of the subjects observed the confederate cheat, while half did not observe any deceptive behavior. The intensity of punitive behavior seemed to vary in accordance with predictions derived from equity theory. That is, cheating for a charity, a “good cause” resulted in less intense punishment than did cheating for selfish gain. On the other hand, mistakes, uncomplicated by cheating, which deprived a charity were punished more intensely than were mistakes whose only result accrued to the confederate himself.  相似文献

The “other regulation” views of Lev Vygotsky and of Jerome Bruner are contrasted with Jean Piaget's self-regulatory model of infant development. Examples of adult behavior in Piaget's writings and in mother-infant interactions suggest that adults perform behaviors which are analogous to Piaget's type a and b self-regulation. Data from infant games are provided to illustrate the processes by which mothers regulate the environments for their infants and the consequences of such maternal regulation for infant development.  相似文献

The present study focused on the executive monitoring of a rehearsal strategy by sixth (11 years 5 months), tenth (15 years 8 months), and twelfth (17 years 9 months) graders and adults (27 years 4 months). The results showed that all of the adults spontaneously adopted an “optimal” strategy and generalized it to a second task. However, none of the sixth graders and only two tenth and three twelfth graders did so. All of the school subjects subsequently trained to rehearse, maintained the strategy without prompting, and showed evidence of transfer. In comparison to adults, the trained subjects' generalized routines became more similar to the adults' as grade increased. This study supports the notion that efficient executive functioning includes the case where continued use of a mnemonic routine is a reasonable response to an objective change in an information-processing task.  相似文献

Personnel representatives (N = 52) were shown one of four videotaped job interviews in which the verbal content of the 16-min interview was identical, but the interviewee's nonverbal behavior was manipulated. A “low nonverbal” interviewee was defined by minimal eye contact, low energy level, lack of affect and voice modulation, and a lack of speech fluency. The “high nonverbal” interviewee demonstrated the opposite behavior on each of these components. The subjects were asked to rate the videotaped candidates on dimensions previously identified as critical in influencing a job interviewer's decisions. Nonverbal behavior was found to have a significant effect on almost every rating made by subjects in this study. After reviewing the entire 16-min interview, 23 of the 26 subjects who saw the “high nonverbal” candidate would have invited him/her for a second interview. All 26 of the subjects who saw the “low nonverbal” candidate would not have recommended a second interview.  相似文献

A simulated lie detection procedure was used to investigate skin conductance responsivity among self-reported skin responders. Subjects were grouped according to reported trait anxiety as measured by Lykken's Activity Preference Questionnaire and then engaged in either a mock crime or a neutral activity. The “crime” gave subjects “guilty knowledge,” and the neutral task provided “innocent associations” to relevant stimuli imbedded in each scenario. Subjects were then interrogated using Lykken's Guilty Knowledge technique. Anxiety classification, guilty vs. innocent treatment, and type of stimulus were manipulated in a 2 × 2 × (2) factorial design. Results for differential responsivity scores showed significant main and interaction effects. Low-anxiety subjects showed almost no effects, but highly anxious subjects responded strongly in the “guilty” rather than the “innocent” treatment. Contrary to previous findings, results showed a substantial—but qualified—relationship between self-reported anxiety and electrodermal responsivity. Also, the Guilty Knowledge technique with rank scoring yielded 97.5% correct classification.  相似文献

In a series of two experiments, male undergraduates either operated or watched another person operate a model racecar set. Instructions varied observers' expectancies about future involvement with the task. The drivers' causal attributions for their performance were compared with those of neutral observers as well as those of involved observers who anticipated running on the track. Predictions, derived from the Jones and Nisbett framework of actor/observer differences, were that actors should make more external than internal attributions and that neutral or “passive” observers should do the opposite. Moreover, the involved or “active” observer groups were expected to display attributional patterns similar to those of the actors. These predictions were confirmed. Results are discussed in terms of information and information-processing differences between groups.  相似文献

Several methods, both new and old, for describing ordinal data with a cardinal model are discussed in a newly developed and general context which broadens their applicability beyond their traditional use in multidimensional scaling. The relationships between the methods is investigated. It is shown that the two most commonly used methods (Guttman's rank-image principle and Kruskal's least-square monotonic transformation) are the boundary conditions of a newly proposed single parameter family of methods. An additional method is proposed which is shown to yield an equal-density model space. The commonly made distinction between “transformation” methods and “transformation-free” methods is shown to be a pseudodistinction. It is observed that all the methods can be stated as matrix operations on the model space with the conclusion that they try to optimize a linear combination of the model space.  相似文献
