To analyze the relationship of logical development and comprehension of syntax, 60 children aged 5-8 years were individually tested. Measures included class inclusion, conservation of substance and weight, a sorting test, and a test of comprehension of active and passive sentences. Class inclusion was not strongly related to syntactical…

The researcher believed that the value of library service could best be measured by its ability to contribute to psychological development via quality reading. Questionnaires were administered to 34 college students, ranging from freshmen to graduate students. The students were tested to determine each individual's level of psychological…

RESEARCH FINDINGS RELATED TO RIGIDITY IN CHILDREN'S PROBLEM-SOLVING ACTIVITIES ARE REVIEWED. EINSTELLUNG RIGIDITY WHICH AFFECTS CHILDREN'S PERFORMANCE IN PROBLEM SOLVING IS CAUSED BY THE MATERIALS AND THE SEQUENCE OF EVENTS INVOLVED IN PROBLEM SITUATIONS. FUNCTIONAL FIXATION OCCURS WHEN CHILDREN ARE UNABLE TO USE OBJECTS FOR PROCESSES IN THE…

This study examined the resistance to conservation of quantity extinction in 180 subjects across the life span. The results indicated that both resistance judgments and explanations were found to develop in a curvilinear fashion, increasing with age until young adulthood and declining thereafter. (JMB)

Corneal infrared photography was used to record the visual fixations of 24 infants (4-6 weeks and 10-12 weeks) exposed to simple geometric figures. The results are discussed in relation to developmental changes in responsiveness to visual figures and in increasing ability to process information. (JMB)

Records of children admitted to a growth clinic and follow-up questionnaires were examined to determine the incidence of learning problems in children with constitutional growth delay and those with familial short stature. (Author/PHR)

In two experiments using a large scale space and a third using a model of that space, the ability of 3-, 4-, and 5-year-old children to coordinate two perspectives of a large scale space was examined. (Author/SB)

This study used a rating scale, a betting game, and a feedback phase to examine the certainty with which 60 second graders and 36 fifth graders made judgments on tasks involving various forms of conservation and transitivity. (Author/JMB)

Presents major considerations in modeling and simulation of variant forms of mental development, provides insight into simulation methods, describes the goals and essential features of two recent models representative of prominent behavioral modeling philosophies, and proposes underlying mechanisms for tow important aspects of development in…

The spatial analogical responding of preschool children, first graders, and college students was compared on two tasks in which body parts were mapped onto drawings of trees and mountains. Results showed that young children performed as well as or better than adults. (JMB)

Hispanic and French Canadian experience have shown that culturally advantaged middle-class students usually have an easier time acquiring a second language than do more socially deprived young people whose parents are not future-oriented--ethnic background is important because some groups place a higher premium on learning another language.…

This study examined the scalability and structural unity of comprehension of ideas from eight positions in the sequential model detailing changes in college students' views of knowledge and authority. (Author/JMB)

The study of 10 congenitally blind and 10 sighted children (ages 3 through 9) indicated that preoperational thought patterns of nominal realism remain longer for blind than for sighted children indicating a delay in (Piagetian) cognitive development of congenitally blind children and their need for appropriate cognitive and linguistic experiences.…
