The present experiments examined the effects of self-focus, as produced by focusing on feelings, on memory. In an initial experiment subjects did complex mental arithmetic significantly faster after self-focus. Because complex mental addition involves internally generated stimuli, the remaining experiments compared the effects, on memory, of self-focus on internally generated stimuli to the effect of self-focus on stimuli supplied by the experimenter. In a second experiment, self-focus facilitated memory for digits recalled in reverse order but not for digits when recalled in the given order. In a third experiment, self-focus facilitated the memory for the classification of digits but not for the digits themselves. In a fourth and fifth experiment, self-focus aided memory for classification of objects into categories such as small, medium, or large but did not aid memory for the objects themselves. In general, improved performance due to feeling focus was attributed to the role that self-focus may play in increasing attention to internally generated stimuli. 相似文献

When letters and words are presented tachistoscopically, material from the right visual field (RVF) can be reported more accurately than that from the left visual field (LVF). The RVF superiority may reflect either left hemispheric dominance for language or directional scanning. Previous studies have deliberately focused on the cerebral asymmetry factor while "controlling" scanning and, thus, have cast some doubt on the potency of the scanning factor. Two experiments were conducted to show that scanning can induce a RVF superiority comparable to that often associated with cerebral asymmetry. The first experiment required bilingual subjects to report six English or six Hebrew letters, shown briefly in either the LVF or RVF, with order of report controlled. A RVF superiority found with English characters was matched by an equal but opposite LVF effect with Hebrew. In a second experiment, five English characters were shown briefly in either the LVF or RVF, and subjects had to identify a single character indicated by a post exposural cue. Using a spatial cue to by pass scanning, there were no field differences; with an ordinal position cue--a procedure thought to force scanning--there was a strong RVF superiority. The results show clearly that scanning can induce visual field differences. 相似文献

The purpose of the present study was to examine the types of discipline enforcement measures employed in the Israeli elementary and junior high schools, and their fairness as viewed by students. The central hypothesis was that patterns of discipline enforcement vary considerably depending on school characteristics. These patterns, in turn, together with students' sex, socioeconomic and ethnic background, and academic status within the school, determine students' perceptions of justice concerning misbehavior management. It was found that junior high school teachers rely more on problem-centered, and elementary school teachers rely more on relationship-centered techniques of discipline enforcement. However, in spite of these differences and the report of about half of the students that they personally had been unfairly treated, the majority of the respondents reported that the punishments employed in their school were generally fair, and that the severity of punishments was in the right proportion to the severity of the misconduct. Students' traits have accounted for only a small percentage of the variance of the various dimensions of justice that were examined. It has been suggested that students' perceptions of justice are related to an overall tendency to perceive schools' authority as legitimate rather than to schools' structural characteristics, misbehavior management techniques, and students' traits. Several possible bases of schools' legitimation are discussed. 相似文献
