A series of four experiments is reported in which reaction times for naming line drawings were analyzed as a function of the similarity of the print superimposed on the drawings to the printed label for the drawing. This effect was studied as a function of grade level (ages 6, 8, and 11 years) and, hence, reading experience. The studies were designed to determine more precisely the characteristics of the stage of visual feature analysis of word identification and to examine response competition factors in this interference task. Results indicated that a combination of end letters and word shape was important for word identification and that response articulation was a significant distinct interference component in this task. 相似文献

Kindergarten children were given simultaneous discrimination tasks with two irrelevant dimensions varying within settings. Prior to each block of eight feed-back trials, the children were asked to attempt to provide a statement of the solution. The introtacts thus provided were found to have several of the desirable characteristics that have been reported for older children with either introtact or blank-trial probes, but which have not been found previously for kindergarten children with the blank-trial probe. Classification of the children according to the trial block on which they first verbalized the correct relevant dimension was found to account for more than 60% of the total variability in discrimination performance. The introtacts were also used to assign parameters to theoretical prediction equations, with nearly two-thirds of the total variability in discrimination performance accounted for by the theory. Extension of the method to other models is discussed. 相似文献

The purpose of the present study was to test the hypothesis that memory for pictorial material is dependent on initial comprehension of the depicted relationships. Subjects at three age levels (second, sixth, and ninth grades) were compared on ability to remember cartoon pictures which did or did not contain action lines as clues to the interaction between actors. It was predicted that the older children, because of extensive experience with still cartoons and comics, would benefit from the action lines. The action lines facilitated recall of pictures for only the older students, specifically, the ninth graders. The object of the action was the most efficient probe, even though the action was more frequently remembered. These results are discussed in terms of the action (interaction) being the basis of comprehension and, consequently, the remembering of the picture. 相似文献

Preschool children in day schools were given instructions to complete certain tasks. Four tasks were given of two types and two levels of difficulty. In each condition compliance with at most one instruction (one task) was reinforced. In two similar experiments, with six children, general results were: compliance with easy tasks was maintained without reinforcement when any task compliance was reinforced; compliance for hard tasks remained high only when that specific task was reinforced. Thus, generalization of compliance with instructions varied with task difficulty. The setting and procedure for both studies were designed to reduce possible coercive features of laboratory studies of generalized performance. Results show generalized performance can occur under naturalistic conditions. The effect of effort, as a response characteristic affecting generalized performance, is discussed. 相似文献

It is a common task to give children a picture containing implicit depth cues and to require them to extract depth information from it. The cues are always selected from the adult repertoire; little is known about children's production of their own cues. In this experiment, 5- to 10-year-old children were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded by the nearer. The results were an age-related decline in the tendency to segregate the objects and an increase in the tendency to group the objects using partial occlusion, with a cross-over at 8 years. At all ages some children drew one object inside the boundary of the other. It is argued that the results are composed of two tendencies, a gradual mastery of discrete scaling phenomena (e.g., “up” on the page means “further”) within a given style, and a set of decisions to be made between incompatible styles. 相似文献

Three philosophical positions on the nature of ethics were examined and contrasted within the context of psychological research: (a) teleology, which involves the balancing of the costs and benefits associated with an action as a means of developing general ethical rules; (b) deontology, which involves the rational adherence to rigid, universal rules that hold irrespective of the situation or consequences; and (c) skepticism, which involves denying the ability to apply universal rules and asserting the individuality of moral codes. Two experiments investigated the degree to which judgments of the ethicality of psychological research are affected by the consequences of the research and judge's ethical ideology. Subjects judged experiments that investigated obedience to an authority as generally less moral and more threatening to the participants' dignity and welfare when the proportion of total obedience was high rather than low. The proportion of participants (10 vs 40%) who were described as “psychologically upset” by the research did not affect moral judgments. These results were obtained across two different obedience situations (Milgram's study and a Watergate study) and different subject populations (high school and college students, males and females). As suggested by philosophers, a judge's ethical ideology determined how the perceived benefits and costs of the research were correlated with moral judgments. Teleologists weighed scientific benefits heavily, deontologists weighed participants' costs heavily, and skeptics weighed both heavily. 相似文献

Research on context effects in impression formation has taken the form of testing competing predictions from the averaging model and the meaning shift model. This between-theory conflict has been unprofitable because neither theory has yet acquired the degree of specificity necessary to generate unequivocal predictions in this area. The research has been useful, however, in identifying each theory's capacity to generate self-contradictory predictions. Future research on this topic can most profitably be addressed to resolving these within-theory conflicts. 相似文献

Based on Jones and Nisbett's (1972) proposition that actor-observer differences in causal attributions derive from differences in attentional focus, it was hypothesized that observers' focus of attention would influence their causal attributions for an actor's behavior. More specifically, it was predicted that the behavior of an actor who was the focus of attention by virtue of some salient physical attribute would be attributed by observers more to dispositional causes and less to situational causes than would the behavior of a less physically salient actor. The manipulations of physical salience were based upon Gestalt laws of figural emphasis in object perception. They included brightness (Study I), motion (Study II), pattern complexity (Study III), and contextual novelty (Studies IV and V). The results revealed that the salinece of the actors' environments (i.e., the other people present) rather than the salience of the actor him/herself had the most consistent influence on causal attributions. When environmental salience was high, behavior was attributed relatively more situationally than when it was low. Prior research findings are considered in light of the proposition that causal attributions for an actor's behavior vary only with the salience of his/her environment, and additional implications of this phenomenon are suggested. Some ambiguities in the application of Gestalt principles to the perception of people are discussed. 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
