This paper highlights the need for a systematic, content aware, and theoretically-based approach to test design. The cognitive components approach is endorsed, and is applied to the development of a computerized perceptual speed test. Psychometric literature is reviewed and shows that: every major multi-factor theory includes a clerical/perceptual…

Involving children 7 and 10 years of age, two experiments aimed to clarify the basis of children's confusion about actions they performed and actions they imagined performing. In experiment 1, subjects were assigned to one of three conditions, each involving two different types of tracing exercises. Children traced simple or complex pictures by…

The ability of 1-month-old infants to recognize their mothers visually was explored with the live faces of mother and stranger presented in three different poses: en face (full face), half-profile, and profile. Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…

This report summarizes the conceptual framework, findings, and methods of the Teacher Beliefs Study, an intensive, two-year program of research on the structures and functions of teachers' belief systems. Eight teachers in three school districts were videotaped over the course of a semester and were interviewed for a total of approximately 20…

Delinquency intervention and research have undergone changes in recent years. One new line of research has been aimed at mapping out juvenile criminal careers.

Theorists have developed various paradigms linking individual media use and interpersonal communication with cultural effects and mass media. Although…

According to Piaget, young children have a profoundly different conception of distance than do adults. In fact, Piaget argues that young children do not have a conception of distance since they do not conceive of distance as being composed of fixed units of space. In contrast, results of a series of studies indicate that in tasks requiring…

A study of the limits of native speakers' awareness of, and ability to express, the dimensions of his language for the researcher investigates this hypothesis: that the ease or difficulty of a native speaker's characterization of the use of the forms of his own language depends on certain general semiotic properties of the use in question.…

According to sociological conventional wisdom, contact of the right kind in the right setting reduces stereotyping. Some research supports this hypothesis, some does not, and most can be challenged because the hypothesis conditions were not clearly met. This study attempted to meet the necessary conditions by using an unusually suitable setting,…

Designed to help children with auditory perceptual problems from fourth through sixth grade, the manual contains essays and exercises to develop listening skills, auditory memory, vocabulary, and imagination.

The technique developed in this research paper for analyzing the information in charts and graphs is designed to reveal design flaws in the display that may prevent them from conveying information effectively. This analytic scheme requires isolating four types of constituents in a display and specifying their structure and interrelations at the…

A battery of assessments to determine the potential contribution of tactual aids to the acoustic perception and speech identification of young deaf children was developed. The tasks were developed so that they could be implemented with standard audiometric equipment and applied to subjects of varying age and to different types of tactual aids.…
