THE THEORY OF DEVELOPMENTAL DYSLEXIA IS CONTRASTED WITH THE THEORY OF DEVELOPMENTAL IMMATURITY TO EXPLAIN EXTREME READING RETARDATION. DYSLEXIA IS DEFINED AS AN ORGANICALLY BASED READING DISABILITY WHICH IS DETERMINED INDIRECTLY SINCE NO ANATOMIC LESION, CHROMOSOME, OR GENE HAS YET BEEN FOUND RESPONSIBLE. DYSLEXIA IS USUALLY DEDUCED FROM (1)…

Answers to the questions "What are Educational Specifications?" and "Why develop Educational Specifications?", are provided along with a discussion of the problems and purposes of the educational program as it relates to the preparation of educational specifications. Environmental interaction and the individual, and environmental factors are…

"Developmental growth" and "average" are two concepts that can be recognized in teachers as well as in students. Inservice teacher training programs must be planned to allow for individual abilities and individual growth. A carefully structured program will (1) fit the program to the personnel, (2) extend over a long time period, (3) have…

The nature of dyslexia is defined and reviewed in the context of neurological and educational processes and the nature of a written language system. An illustrative case history of a typical dyslexic child is presented. The nature of a script system is examined in the light of current linguistic and psycholinguistic studies. Noted are…

The primary purpose of this research is to determine if there exists covert confounding in student perceptionnaires which significantly affect instructors ratings. Eight calculus classes were randomly selected. Each student completed a Texas A & M University (TAMU) student perceptionnaire the first day of class, envisioning having completed the…

Three known methodological approaches were investigated as to their within-test correlative support in the measurement of a phenomena called imagery. Based on these methodologies, repeated dichotomization of subjects into high and low visualizers was significantly consistent. Moreover, self-reported ratings of imagery vividness of prose were…

The basic parameters of intrinsic motivation to work are explored. Principles are sought relevant to ways of redesigning jobs to increase their intrinsic motivation properties and to avoid task overload and boredom. Coordinated field and experimental laboratory studies are described. (Author)

The purpose of this study was to examine the effects of verbal and perceptual aspects of learner aptitude, in relation to inspection behaviors performed while learning from written materials containing two modes of instructional content. Science instructional materials containing both text and diagrams were modified by (1) inserting questions that…

The present study was designed to investigate the role of expectations in self-concept and level of aspiration (LOA) behavior. Specifically, the focus was to investigate self-concept and LOA as covariates and to describe the nature of the relationship if, in fact, one existed. A sample of 80 third and fourth grade students was selected from three…

This study demonstrated the efficacy of a Likert format in contrast to two choice formats in eliciting a more normal distribution of internal-external locus of control responses in a highly variable lower class university sample. The revised Likert format, in contrast to the original, collaborated other research evidence suggesting a multifactor…

The hypothesis that individual differences in psychological differentiation are related to the perceptions of the independence of leadership behaviors was tested. After viewing a supervisor-subordinate interaction sequence on closed circuit television tape, subjects responded to questionnaires measuring their perception/judgments of the…

This study examined possible relationships between the analytic/global dimension of cognitive style, as defined by Davis and Klausmeier (1970) and measured by the Children's Embedded Figures Test (CEFT), and two modes of instruction varying in the level of guidance provided the learner. Sixty Anglo subjects (eight and nine years old), identified…

The purpose of the study was to investigate the magnitude of individual differences in time-to-criterion and the stability of these differences. Time-to-criterion was defined in two ways: the amount of elapsed time required to attain the criterion level and the amount of on-task time required to attain the criterion level. Ninety students were…

The studies described in this report were concerned with the effect of active student behaviors, such as note-taking, listening, verbal responding, and test-taking, and the effect of individual differences on the transformation, storage, and retrieval of information. The roles of such individual characteristics as personality, background, and…

In order to help students to be more efficient decision makers, it is essential to consider individual differences in the decision making process. The problem of this study was to determine the influence of specific internal and situational factors on the amount of information demanded prior to making risky decisions. Factors studied were category…
