When head-movement parallax functioned as the sole veridical distance cue during exposure to spectacles that altered the eyes’ oculomotor adjustments, sizable adaptation was obtained. This result showed that a discrimination of the distances of 60 and 30 cm can be based on head-movement parallax. Using adaptation in demonstrating that head-movement parallax can serve as a distance cue circumvents the problem that the presence of accommodation normally presents when such a demonstration is attempted. The usual contamination of head-movement parallax with accommodation is avoided, because accommodation is altered by the spectacles and does pot function as a veridical cue along with head-movement parallax. 相似文献

In Experiment 1, it is shown that during reading the eye makes larger saccades near long words than near short words. The effects are reduced when the subject’s peripheral vision is diminished by the use of a moving “window” centered on the subject’s fixation point, outside of which letters are replaced by Xs. In Experiment 2, it is shown that even if linguistic predictions are kept constant, the eye tends to make longer jumps when approaching THE than when approaching a three-letter verb. This “THE-skipping” effect is weaker if THE is compared with an auxiliary (HAD, WAS, or ARE) than if it is compared with a less frequently occurring verb (ATE, RAN, MET). It follows that knowledge of the lexicon can combine with information from peripheral vision fast enough to influence saccade size from moment to moment. 相似文献

The effect of using teachers as behavioral observers on both student and teacher behavior was examined with eight teachers and 32 elementary school children. The frequency of prompts (but not praise or criticism) to those students observed by the teacher increased significantly from nonobserver to teacher observed experimental phases. In addition, students observed by the teacher showed more change in appropriate behavior than students who were not observed. The significance of these findings for research and therapy is discussed. 相似文献

This study investigated seven factors relating to personal preferences in choosing a career. Differences between male and female preferences were also studied. While males and females express similarities relating to the seven factors, they also reveal differences that should be considered by counselors helping individuals explore career choices. 相似文献

Language and disfluency variables in normal speaking children from discrete chronological age groups
Thirty male and female children from three chronological age groups were compared on Developmental Sentence Score, total words spoken in a language sample, total disfluency, and eight specific disfluency subtypes. Analyses were performed to determine in differences existed among the three age groups, between sexes, and whether language and disfluency were related. No sex differences in either language or disfluency were found. Total disfluency showed only a slight decrease with an increase in chronological age between 4 and 8 years. This suggests that the major disfluency decrease must occur subsequent to age 8. Although the total disfluency changed minimally between ages 4 and 8, some of the disfluency subtypes shifted considerably. Older children were almost as disfluent as younger children, but the topography of their disfluency was different. No significant relationship was found between the disfluency and language variables studied. 相似文献

The experiment was designed to test differential predictions derived from dual-coding and depth-of-processing hypotheses. Subjects under incidental memory instructions free recalled a list of 36 test events, each presented twice. Within the list, an equal number of events were assigned to structural, phonemic, and semantic processing conditions. Separate groups of subjects were tested with a list of pictures, concrete words, or abstract words. Results indicated that retention of concrete words increased as a direct function of the processing-task variable (structural < phonemic 相似文献

The development of guidance services in Irish schools since the sixties is described and discussed. Provision for the full-time training of guidance teachers began in 1967, and after a brief attempt to use short courses as a substitute, this has now been accepted as the standard form of basic training. Since 1972 approximately 90 guidance teachers have qualified each year, and by 1974 they were present in about 24% of post-primary schools. Data is reported from a survey of early graduates from the one-year course at University College Dublin, and also from a survey of the attitudes to guidance of the heads of schools with guidance teachers. Some comments are also provided on the current status of guidance in Ireland. 相似文献
