Parallels between sign stimuli and speech cues suggest some interesting speculations about the origins of language. Speech cues may belong to the class of human sign stimuli which, as in animal behavior, may be the product of an innate releasing mechanism. Prelinguistic speech for man may have functioned as a social-releaser system. Human language…

The first paper in this booklet summarizes the desegregation strategies that have been used either singly or in combination to ethnically balance schools.

A model postulating a relationship between faculty research activity, instructor behaviors, and student achievement is advanced, based on two causal models, one linking research activity and instructional effectiveness and another validating student evaluations as good indicators of instructional effectiveness, as measured by student achievement.…

Information and Library Services at the University of Maryland University College conducted a needs assessment survey to examine trends in student use of library resources, services, and instruction in order to understand how student usage patterns, needs, and preferences have changed as well as stayed the same. Findings followed national trends…

Attention during reading lessons was explored for 116 second and third graders (60 males and 56 females). Some of the concurrent and antecedent factors that influence attention were investigated. Oral reading errors undermine attention. Nominal reading group membership is more strongly related to attention than individual fluency and comprehension…

Effects of mothers' need for approval on children's expectancies for success and persistence during failure were studied for 90 fifth graders attempting to solve 4 puzzles, 3 of which were unsolvable. Parental and situational variables affect children's achievement cognitions and behavior. Implications for parental socialization of achievement are…

Tests a model of the effects of negative social sanctions that considers the mediating effects of self-rejecting feelings associated with perceived rejection and failure. Results with 1,925 seventh graders asked about drug use are compatible with theoretical premises underlying the predicted association between negative social sanctions and…

Disruptive behavior patterns are particularly challenging for parents, teachers, and peers as these behaviors often interfere with classroom instruction, frequently lead to academic underachievement, and are associated with social skills acquisition and performance deficits. Children who exhibit a combination of…

We suggest that this link has not been adequately addressed by studies of information behaviour, though a…

While Gottlieb recognized the significance of biological factors for behavioral development, the system of psychology he developed did not cast the discipline as a purely biological science. Rather, genes, brains, hormones were understood by him as participating, rather than causal factors in behavioral origins. He worked from two basic principles…

This study explored how Taiwanese upper-elementary-school students' motivational characteristics were related to their decisions regarding avoidance of help seeking in the classroom context. Two hundred and ninety-eight sixth-grade students completed a self-report survey assessing their attitudes and behaviors related to help avoidance,…

Purpose: This paper seeks to examine the spatial patterns of student use of machines in each laboratory to whether there are underlying commonalities. Design/methodology/approach: The research was carried out by assessing the user behaviour in 16 computer laboratories at a regional university in Australia. Findings: The study found that computers…

Background: The main objective of this study was to develop a comprehensive, empirical model that would allow the reorganization of the structure of the pervasive developmental disorder symptom phenotype through factor analysis into more homogeneous dimensions. Method: The sample consisted of 209 children with pervasive developmental disorder…
