The use of teachers as behavioral observers

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.     

Male and Female Preferences in Selected Career Factors

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.     

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.     

Memory for pictures and words as a function of level of processing: Depth or dual coding?

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   

Guidance and counselling in Irish schools

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.     

Influence of temporal masking on click-pair discriminability

When temporal auditory acuity is estimated using time-reversed click pairs, the asymmetry of temporal masking may influence the results. To investigate this hypothesis, we first established normal-hearing listeners’ psychometric functions for the discrimination of time-reversed click pairs. An attempt to relate listeners’ performances in click-pair discrimination to their performances in forward and backward masking tasks was unsuccessful, probably due to the presence of spectral artifact in the temporal masking paradigms. We then investigated listeners’ abilities to discriminate time-reversed click pairs in which the intensity of the lower level click in one pair was altered. This alteration was introduced at random in order to minimize the influence of spectral artifact. Our results suggest that the course of temporal masking influenced the discriminability of the modified click pairs. Thus, the discrimination of time-reversed click pairs may yield a biased estimate of auditory temporal acuity.     

Hypersexuality and limbic system seizures

Hypersexual behavior was induced in adult male cats by repeatedly evoked limbic system seizures. Accentuation of Dopaminergic activity with drugs was used to facilitate development of the seizure induced hypersexuality. Hypersexuality consisted of biting knap of neck, mounting, thrusting and coital intromission. The gradual development and eventual disappearance of hypersexuality was correlated with the progressive prolongation of the seizures in their evolution. There are three stages of seizure evolution in relation to sexuality. First stage-normal sexuality, intermediate stage-hypersexuality and late stage-hyposexuality. A theoretical “hypersexual growth and decay curve” was constructed in relation to the evolution of limbic seizure durations in the intermediate stage. It was suggested that the observed hypersexuality was related to the early discharge activation of hypothalamic, preoptic and basal ganglia neurohumeral facilitatory mechanisms for sexuality, and the late effects were related to discharge activation of brain stem serotonergic inhibitory mechanisms. The discussion attempts also to use these experimental findings to explain clinically observed hyposexuality and hypersexuality. It was suggested that either hypersexuality or hyposexuality may be associated with psychomotor seizures and that the predominating sexual state at a given moment is dependent upon the evolutionary stage of the seizure at that moment. Consequently, psychomotor seizures with associated hypersexuality should not be considered a clinical anachronism. In fact, these observations support the impression that rape may be a manifestation of a psychomotor seizure.
