People often find that they do not have some positive outcome they once expected to obtain, while others around them have attained that outcome. Two experiments were conducted to assess how four possible responses to such a situation are affected by procedural justice (i.e., the fairness of the procedures by which the object was denied) and by one's expectations about obtaining the outcome in the future. The four possible responses examined were anger responses, achievement strivings, devaluation of the object (X), and self-deprecation. A repeated-measures analysis revealed that the dependent variables were differentially affected in Study 1, but less so in Study 2. Analyses further revealed effects of procedural justice, such that unfair procedures led to more anger, lower achievement strivings, greater devaluation of X, and (in Study 1 only) marginally less self-deprecation. Expectations had only a marginal affect on achievement strivings in Study 1, and an effect on self-deprecation in Study 2, with higher expectations leading to lower achievement strivings and less self-deprecation, respectively. Procedural justice and expectations interacted to affect subjects' derogation of the agent who deprived them (Study 1) and their devaluation of X (Study 2). Implications for future research and for theoretical development are discussed. 相似文献

An experiment is reported in which the effects of taxonomic organization on 7-year-old and 11-year-old children's free and cued recall of two- and four-category lists were examined. The data were analyzed using a stages-of-learning model that simultaneously delivers estimates of the impact of these manipulations on storage and retrieval components of recall. The results indicated that for the Grade 2 children providing a category label at the time of recall primarily enhanced storage whereas increasing the number of categories primarily enhanced retrieval. For Grade 6 children, on the other hand, the use of category labels to cue recall primarily enhanced retrieval, whereas increasing the number of categories affected both storage and retrieval in free recall, but only retrieval in cued recall. In addition, while older children were superior to younger children at both storing and retrieving information, age differences at retrieval were generally larger than those at storage. 相似文献

The use of spelling-sound information in both reading and spelling was evaluated by having children read and spell nonwords and five types of words that differed in terms of their regularity for reading and spelling. The subjects were grade 3 children who had been psychometrically defined as good readers and good spellers (“good”), good readers and poor spellers (“mixed”), or poor readers and poor spellers (“poor”). Results indicated that all children attempted to use spelling-sound correspondences in both reading and spelling, although children in both the mixed and the poor groups had weaker knowledge of these correspondences and were less systematic in their use of them. Furthermore, even though the children in the mixed group had been matched with children in the good group on reading comprehension, the number and type of errors made by the mixed subjects on both the reading and spelling tasks were more similar to those of the poor subjects than to those of the good subjects. 相似文献

It was hypothesized (1) that with age children would rely increasingly upon information about intention, rather than overt
behavior, when attributing dispositional features to others; and (2) that, developmentally, “restricted” dispositional attributions
(i.e., those that assume the operation of highly specific situation-response relationships) would precede “generalized” dispositional
attributions (which assume the operation of a dispositional concept between broad classes of situations and responses). An
experiment is reported that provides support for the first, though not the second, of these hypotheses. 相似文献

A follow-up study with a younger group of mildly handicapped Japanese students was conducted to determine if the correlations between the Developmental Test of Visual-motor Integration and reading and mathematics achievement would substantiate the previous findings. For 30 mildly handicapped 11- and 12-yr.-old Japanese students, visual-motor integration scores were significantly correlated with both mathematics and reading scores. These results, added to the 1984 Webb and Abe data, further support the test's cross-cultural validity. 相似文献

Fourth-, fifth-, and sixth-grade students responded to a questionnaire concerning their experiences with electronic videogames and computers. Teacher ratings of academic achievement, personality characteristics, and behavior patterns were also obtained for each student. These data were used to examine a number of hypotheses concerning potential harmful or beneficial effects of electronic videogames on school-age children, and to provide preliminary evidence concerning the correlates of computer usage by school-age children. Videogame usage showed significant positive correlations with teacher ratings of impulsivity, significant negative correlations with ratings of academic achievement, and little relationship to rated sociability. Videogame use also proved positively related to other social activities and to microcomputer use. 相似文献

Certification is the process whereby older juveniles who have committed felony offenses are transferred from juvenile courts to adult courts. The present study examined the variables that influence decisions in these cases and used attribution theory to conceptualize the process. Data were obtained from files of 150 youths on whom certification petitions had been filed from January 1981 to October 1984. Of these, 125 had been certified and 25 had not. The sample comprised 148 males and 2 females. Data included seriousness of the offense, previous offenses, potential for aggressiveness, level of involvement in the offense, age, court in which the case was heard, year in which the case was heard, IQ, family income and sex. Level of involvement, seriousness of the offense and potential for aggressiveness had the strongest association with certification outcomes, with those high on these measures significantly more likely to be certified. The cluster that predicted outcomes best included level of involvement, seriousness of the offense, potential for aggressiveness, IQ, year in which the case was heard, court in which the case was heard, sex and previous offenses. The most explicitly behavioral variable—how actively the child participated in the offense—was the best single predictor of outcomes. 相似文献
