Since previous data suggested that the magnitude of orienting evidenced by cardiac deceleration increased over the first 16 weeks of life, 6- and 16-week-old infants were compared on various characteristics of orienting: habituation, dishabituation, and magnitude of deceleration to stimulus offset as well as to stimulus onset. Neither the change in stimulus following habituation trials nor the stimulus offset produced a large enough response to confidently evaluate age differences suggested by the data. Stimulus onset elicited a pronounced deceleration which for the two age groups was of equivalent magnitude on initial trials and declined similarly with stimulus repetition. It was suggested that similarity of the two age groups on these parameters was due to control of state within a narrow alert range, and that, in general, younger infants are less likely than older infants to show orienting when conditions for orienting are marginal.  相似文献

A study was conducted to test the reasoning that two types of dispositional self-consciousness would be associated with two different influences on compliance behavior. The study utilized a paradigm in which subjects are induced to make incorrect responses on a perceptual task by means of simulated group pressure. Based upon results of previous research, the following predictions were made: that private self-consciousness—the disposition to be conscious of one's thoughts, feeling, and covert self-aspects—would be inversely correlated with compliance; and that public self-consciousness—the disposition to be conscious of one's social self-aspects—would be positively correlated with compliance. The data from the study provided support for both of these predictions. Discussion centers on the theoretical implications of these findings.  相似文献

Subjects judged the cumulated risk of dying during a year for a set of persons or cases each characterized by the risks during three different periods of risk exposure during the year (e.g., 18 weeks with 2.3 deaths per thousand persons per year of exposure, 28 weeks with 2.5 deaths and 6 weeks with 16.0 deaths per thousand per year). Three main strategies were used for solving the problems: (1) addition of the risk levels, (2) computing the mean of the risk levels, and (3) the most frequently used anchoring and adjustment strategy most closely approximating the normatively correct risk over the year. The first two strategies do not use all relevant information because they neglect the importance of different exposure times. The anchoring and adjustment strategy used all information and was executed in a first stage in which an initial anchor or reference risk was selected followed by a second stage in which this anchor was adjusted according to the remaining information. The process for finding the first anchor was quite flexible, using different principles (e.g., extreme values or similarity) depending on the pattern of cues characterizing each case. Biases in relation to normative theory originated from subjects misunderstanding or simplifying the problem (Strategies (1) and (2)) or the characteristics of the anchoring and adjustment process which resulted in relative overestimation of short-time, high-risk cases. A few subjects, however, all of whom used sequential anchoring and adjustment, succeeded in giving quite accurate estimates.  相似文献

Subjects in three experiments evaluated hypothetical actors whose claims about either an upcoming or past performance and whose performances were system-atically varied from very positive to very negative. Positive, self-enhancing claims were effective in generating favorable evaluations when either the claim was congruent with the performance or the subjects were unaware of how the actor performed. In general, accurate self-presentations were most favorably evaluated, especially when the claim occurred after the performance. The two exceptions to the preference for accurate self-presenters occurred when (a) the actor modestly underestimated a clearly superior prior performance by claiming to have done “only” well or all right, in which case he/she was evaluated more favorably than an accurate but seemingly boastful actor who claimed to have done extremely well, and (b) the actor self-deprecatingly predicted an inferior performance, in which case he/she was disliked even when accurate. Disclaimers about the importance of the performance (e.t., “I did well, but it's no big deal”) were seen as boastful rather than modest and decreased evaluations. The results mirror many of the tactics used by actor-subjects in past experiments, suggesting that people generally vary their self-presentations in optimal fashion to create the most favorable possible impression on the audience.  相似文献

According to previous research, young children do not understand displaced aggression. The present study examines the early phases of the understanding of the causes of moderately and extremely displaced aggression. Preschool and kindergarten children (3 to 5 years of age) viewed eight videotaped episodes of displaced aggression. Their comprehension of this aggression was assessed by means of open ended questions and forced choice picture selections. By age 5 most children had some understanding of displaced aggression, but this understanding was not complete. The early understanding revealed in the present study may be due to the use of short, simple realistic videotaped episodes appropriate for the limited processing abilities of young children. Extreme displacement was not more difficult to understand than moderate displacement.  相似文献

Three studies examined young children's ability to predict how certain internal and external conditions affect behavior. Study 1 included 136 children from early preschool, late preschool, kindergarten, and second grade. A forced choice procedure revealed that even the youngest group could predict the effect of various internal-personal causes (e.g., interest, intelligence) and external-situational causes (e.g., rewards, adult pressure). Older preschoolers and second graders considered these internal causes more powerful than these external causes. With the same procedure, in Study 2 the 16 preschoolers predicted that both physical characteristics (e.g., strength, energy level) and the internal-personal characteristics of Study 1 affect performance in athletic activities. In addition, they considered the physical causes more important. Study 3 examined more complex types of causal reasoning. Younger preschoolers responded randomly but older preschoolers combined two causes to create a greater effect than one cause and used an external cause to enhance, rather than discount, an internal cause. The discussion focused on the cognitive development underlying developmental differences in the ability to predict behavior on the basis of one or two causes.  相似文献

This study examined developmental changes in the understanding of distractibility. It focused on how information about both interest level and noise level are used to form judgments of how many items a hypothetical child would learn. A total of 112 subjects from grades K, 2, and 5 and college age used a rating scale to judge the amount of learning in situations generated by a factorial combining of three levels of interest and three levels of surrounding noise. Children at all ages, even kindergarteners, used both noise and interest information in making their judgments. Interest level influenced judgments much more than noise level at all ages, but this imbalance waned somewhat with increasing age. The rules for combining noise and interest were more complex at the older ages. The discussion focused on interpretations of the subjects' belief that interest level heavily influences attentiveness.  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

Sixty male and sixty female college students, representing three of Kohlberg's stages of moral judgment, were exposed to a complicance situation in which their personal count of a series of metronome clicks was contradicted by a unanimous group. Group differences were either one or two steps from veridical. For half of the subjects self-awareness was experimentally increased. The results indicated that subjects in moral judgment Stages 3 and 4 complied significantly more than Stage 5 subjects. The self-awareness manipulation produced a complex pattern of results in the form of a three way interaction with moral judgment and type of compliance. Finally, sex differences in compliance behavior were significant, with females complying more than males. The results were discussed in terms of a cognition-behavior relationship.  相似文献

In a theory chain extending Byrne's theory of social attraction, links are described between breadth of social interaction and complexity of the self-concept as well as between complexity of the self-concept and social attraction. In the first series of studies, it was shown that communication-handicapped adolescents and physically handicapped children, as well as terminally ill patients, indicate lower self-complexity. In a second series of studies, it was found that persons with more complex self-concepts identify more closely with others, perceive themselves as more similar to objectively dissimilar others, and are more popular sociometrically.  相似文献

The nature of hemispheric processing in the prelingually deaf was examined in a picture-letter matching task. It was hypothesized that linguistic competence in the deaf would be associated with normal or near-normal laterality (i.e., a left hemisphere advantage for analytic linguistic tasks). Subjects were shown a simple picture of a common object (e.g., lamp), followed by brief unilateral presentation of a manually signed or orthographic letter, and they had to indicate as quickly as possible whether the letter was present in the spelling of the object's label. While hearing subjects showed a marked left hemisphere advantage, no such superiority was found for either a linguistically skilled or unskilled group of deaf students. In the skilled group, however, there was a suggestion of a right hemisphere advantage for manually signed letters. It was concluded that while hemispheric asymmetry of function does not develop normally in the deaf, the absence of this normal pattern does not preclude the development of the analytic skills needed to deal with the structure of language.  相似文献

Sixty-four kindergarten children received tests of quantitative identity and quantitative equivalence for the conservations of number and continuous quantity. Two types of identity trials were included: a standard version using a single stimulus, and a modified version which paralleled the equivalence task in its use of two stimuli. In addition, half of the children were asked two questions on each trial (one preceding and one following the transformation), whereas half were asked only the post-transformation question. Neither the number of stimuli used nor the number of questions asked had any effect on performance. In contrast to some previous reports, tests of quantitative identity were no easier than tests of quantitative equivalence. It was concluded that the identity-equivalence décalage, if it exists at all, is less important than previous authors have claimed.  相似文献

In an exploration of the personal basis of resistance to authority, moral judgment and attitudes toward authority were examined in 183 men and women political resisters, including antinuclear, draft registration, and tax resisters, and anarchists, and compared to 34 liberal and 29 conservative activists. The measures used were the Defining Issues Test and a specially designed attitude survey. As predicted, the differences between resisters and nonresisters were in the realm of cognitive beliefs and values. Strong rejection of political and social authority, a belief that individual conscience is a better guide to conduct than the law, a professed unwillingness to be in positions of authority over others, and a lack of conventional religious affiliation significantly differentiated the resisters from the nonresisters. The resisters also measured high in level of moral judgment but were significantly different only from the conservatives.  相似文献

To assess the development of dichotic ear asymmetries and handedness, 208 male school children were evaluated in kindergarten and at Grades 2 and 5 (ages 66, 92, and 130 months of age, respectively) with a dichotic listening task and a hand preference test. The Wide Range Achievement Test (WRAT) also was administered at each of the three grade levels. There was significant variability in handedness scores over time only for those subjects whose scores at initial testing, that is, in kindergarten, identified them as non-right-handers. Both right and left handers had a significant increase in dichotic listening scores over time; however, only right handers had a significant right ear advantage at each evaluation. Regression analyses showed that combined hand preference scores and ear recall scores at each probe when combined accounted for almost 44% of the variance in WRAT achievement scores at Grade 5. Ear asymmetry scores, however, were not predictive of school achievement.  相似文献

Three experiments explored the development of three linguistic aspects of more in children's speech. Subjects were 56 children between the ages of 2;6 and 6;0. Experiment 1 addressed the nature of the early semantic content of more. Experiment 2 examined the child's differentiation of mass more from count more. Experiment 3 explored the child's use of more as a comparative marker on adjectives. The results suggest, first, that the child initially stores the meaning of more with a prototype, rather than with some more systematic, featural representation. In addition, children's linguistic understanding of the dual use of more as a quantifier of mass amounts and count amounts does not appear to develop until long after they have been using more appropriately in unambiguous contexts. Finally, children learn to use more as a marker on comparatives only after they have acquired -er as a comparative marker, and some time after they have been using more successfully in nonadjectival constructions.  相似文献

Subjects were asked to make evaluations in each of three tasks—a gambling task, a consumer judgment task, and a student evaluation task. Each task involved two important attributes, but information about one attribute was missing on some trials. Half of the subjects received a version of the task in which a key attribute was presented in positive terms (e.g., probability of winning a gamble) and half received a version in which that same attribute was presented in negative terms (e.g., probability of losing a gamble). Even though the information was objectively equivalent in the two versions of each task, there were two significant framing effects. (1) In all tasks, responses to two-attribute stimuli were more favorable in the positive condition than in the negative condition. (2) When the key attribute was missing, evaluations of one-attribute stimuli relative to evaluations of two-attribute stimuli were lower in the positive condition than in the negative condition. Results were discussed in terms of the constructs of prospect theory and information integration theory.  相似文献

The Fishbein-Ajzen behavioral-intentions model is designed to represent the effect of attitudes and subjective norms on behavioral intentions. The model has been used in a variety of contexts, and evidence for its validity flows largely from its generally good performance in predicting behavioral intentions. However, the manner in which these concepts are defined and operationalized appears to make it inappropriate for those seeking to distinguish between personal and normative reasons for engaging in a behavior. Additional problems were found in the hypothesized relationship between the more global normative construct and its underlying components.  相似文献

Two studies investigated why the presence of conspecifics reduces open-field fear. In Experiment 1 rats paired with another experimentally naive rat were not less fearful than alone controls. However, rats paired with a partner who had been preexposed to the open field exhibited fewer fear responses than alone controls. Since preexposed companions appeared to initiate more social interactions than nonpreexposed companions, it was argued that the preexposure effect could be the result of preexposed companions distracting actor rats from threatening stimuli. Experiment 2 tested this explanation by pairing socially sated or socially deprived rats with a socially sated or socially deprived companion. In accord with a distraction hypothesis, pairing two socially deprived rats produced the greatest fear reduction effects and also led to more social interaction than pairing socially sated rats. Alternative explanations involving conditioning and communication are discussed.  相似文献

The present study addressed the question of Levy's (1974, Psychobiological implications of bilateral assymetry. In S. Dimond &; J. G. Beaumont, Hemispheric function in the human brain, NY: Halstead. Pp. 121–183.) proposal that left handers would have lowered spatial skills relative to verbal skills. In the first part of the study, performance on the PMA (visuospatial subtest) and WAIS Block Design subtest were compared between right and left handed high school and college samples. No support could be found for deficient visuo-spatial performance in the left handers. In the second part of the experiment, no relative impairment of visuospatial skills was found when subjects were classified into predicted speech dominance groups on the basis of a dichotic listening task and/or a visual half-field task. An extreme groups comparison of the most left dominant and most right dominant groups again yielded no significant differences in visuo-spatial performance. Finally, the relationship between degree of speech lateralization and visuo-spatial skills was examined. Only partial support for differences in cerebral organization for speech in left handers was found in the college sample.  相似文献

High school dropouts (N = 100) and high school graduates (N = 100), of which half of each group had received vocational training and the other half had not, were compared on data taken from the inactive employment applications of the Fort Walton Beach, Florida State Employment Office. The sample (N = 200) consisted of an equal number of males and females while 30% were minority group members. A two-way analysis of variance showed that completing vocational training was positively correlated with higher income and job complexity level. The existence or absence of vocational training was a more potent influence on income level and job complexity than was completion of high school.  相似文献
