In a study on cognitive style, reflectivity-impulsivity in response to task uncertainty was investigaged. At 44 months of age, 23 boys and 25 girls were tested on a matching-figures test. Correlations were made between number of errors, response time, intelligence, and sex. Results indicated that there were significant sex differences in preschool…

The research concerned the association of neutral objects, such as nonsense syllables, with rewards, such as money and candy, in children. Thirty-six subjects were obtained from grades two through six of local public elementary schools in Nashville, Tennessee. Associations between neutral objects and rewards were formed in a task concerning…

Seven 18- to 32-month-old children received from seven to 26 experimental sessions each between October 1966 and April 1967. A session lasted from 5 to 15 minutes and concerned control over the verbal responses of the children with token-operated reinforcement devices. In order to make the results of the experimental sessions meaningful, an…

One control group and eight experimental groups, each composed of 12 first grade children, participated in this experiment. It was designed to investigate the effects of frequency of reinforcement and repeated evaluation of stimuli on the conditioning of preferences. Each child participated in the experiment for seven consecutive school days. The…

Men's and women's immediate reactions to completing the Self Directed Search (SDS) and the Strong Campbell Interest Inventory (SCII) were assessed, as well as the impact of this testing on their subsequent behaviors four weeks later. A random sample of college freshmen at the University of Kansas (N=96) completed either the SDS, SCII, or both…

Two types of sensitivity indices were developed in this paper, one internal to the total test and the second external. To evaluate the success of these statistics the three criteria suggested for a satisfactory index of item quality were considered. The Internal Sensitivity Index appears to meet these demands. Certainly it is easily computed. In…

A conventional vocabulary test and two forms of a stradaptive vocabulary test were administered by a time-shared computer system to undergraduate college students. The two stradaptive tests differed in that one counted question mark responses (i.e., omitted items) as incorrect and the other ignored items responded to with question marks.…

This study empirically investigated the validity and utility of the stratified adaptive computerized testing model (stradaptive]developed by Weiss (1973). The model presents a tailored testing strategy based on Binet IQ measurement theory and Lord's (1972) modern test theory. Nationally normed School and College Ability Test Verbal analogy items…

The VHF system used by the Satellite Technology Demonstration had a built-in digital response system to collect data about student programing. This paper describes the hardware and software required to implement and operate the system. In addition, information on the applications of this device is provided along with the results of a field…

This state assessment at the third-grade level is the first stage of a proposed three-year evaluation cycle of third, sixth, and ninth grades in North Carolina to aid personnel in making accurate decisions regarding improvement in the social studies curriculum. Students were randomly selected to represent the third-grade population in the state…

Interaction theory has not been applied to interpersonal communication because the Western scientific model requires that variables be consciously apparent. A simple model of sending and receiving is not adequate to explain the complex nature of human communication, however. The dyadic pattern of interrelationship may be expanded to reflect the…

The purpose of this study is to examine the organization of play space and the effect which this organization has on children's productive and disruptive behavior in an indoor nursery setting. A second purpose was to develop a category system for recording the productive and disruptive behavior of young children in a free play situation. The…

Data on the attention patterns of Sesame Street's intended target audience were analyzed and compared with data on middle-class children. Attention scores gleaned from a series of formative research studies performed in New York day care centers in 1972 and 1973 yielded the following conclusions: (1) within each of the four categories of affect…

This study investigated the relative effectiveness of verbal and visual modes of presentation on the learning of paired-associates by 64 3-year-old and 64 8-year-old children. Nine pictorial paired-associates and 9 verbal paired-associates were formed from pictures or names of familiar objects. At each age level, 8 male and 8 female subjects were…

The result of a number of experiemental studies of human auditory and visual information processing behavior and their possible relationship to the student pilot's acquisition of flying skill were explored in terms of a conceptual model developed for this study. The results were interpreted in terms of the potential interfering effects of the…
