This article proposes and tests a formal cognitive model for the go/no-go discrimination task. In this task, the performer chooses whether to respond to stimuli and receives rewards for responding to certain stimuli and punishments for responding to others. Three cognitive models were evaluated on the basis of data from a longitudinal study…

When an odor is paired with a delayed illness, rats acquire a relatively weak odor aversion. In contrast, rats develop a strong aversion to an olfactory cue paired with delayed illness if it is presented simultaneously with a gustatory cue. Such a conditioning effect has been referred to as taste-potentiated odor aversion learning (TPOA). TPOA is…

Reproduction training improved performance only on the reproduction test; discrimination training improved performance only on the discrimination test. The effects of discrimination were seen both on forms used in training and on other similar forms, while the effects of reproduction training were seen only on trained forms. (Author/BJG)

This study investigated the effects of two stimulus manipulations (spatial distinctness and number of dimensions) on the performance of 24 kindergartners and 24 fifth graders in (1) tasks requiring distributed attention and (2) tasks requiring selective attention. Results suggest that kindergartners attempt to use one processing mode (distributed…

TO COMPARE SEVERAL METHODS OF DEVELOPING CLASSROOM QUESTIONING (PROBING) TECHNIQUES VIA DISTRIBUTED PRACTICE AND IMMEDIATE FEEDBACK, WHEN THE LATTER EMPLOYED VIDEOTAPED PERFORMANCES OF THE LEARNER, 85 INTERNS WERE VIDEOTAPED ON 4 OCCASIONS DURING THE FIRST 20 MINUTES OF REGULAR CLASSROOM LESSONS. IN BETWEEN TAPINGS THEY RECEIVED 30 MINUTES OF…

A NEED TO DETERMINE THE VALUE OF PRELIMINARY DISCRIMINATION TRAINING IN INCREASING THE EFFECTIVENESS OF LANGUAGE LABORATORY PRACTICE ON THE PRONUNCIATION OF FRENCH SOUNDS HAS RESULTED IN THIS STUDY. DESCRIBED IN CHAPTER 2 ARE ELEVEN PILOT STUDIES, INVOLVING MORE THAN 1,000 STUDENTS, THAT PERMITTED THE DEVELOPMENT OF MATERIALS, TRAINING PROCEDURES,…

This document includes 10 articles dealing with five specific areas of language development. Two articles and a commentary cover each area. Resumes of the articles have been assigned the following numbers: memory functions (PS 001 487 and PS 001 488), associations and verbal habits (PS 001 489 and PS 001 490), language perception and…

Earlier studies found that recall scores of information central to the task increased with age while incidental information recall scores remained constant. This study repeated the earlier ones modifying procedures of instructions, testing, and schedule of recall. Also, it tested the effect of labeling pictorial stimuli. The sample of 253 children…

Seventeen preschool children were administered two color-discrimination pretests, verbal and nonverbal. The five children who scored lowest were chosen to recieve the color program. Four scored elow 85 percent on the nonverbal pretest, whereas the other 12 children scored above 85 percent. On the verbal pretest, all five experimental subjects…

This study analyzes the generalization abilities of children with reading disabilities by comparing the performance of such children with that of a normal control group on a conditional discrimination learning-set task. Both groups, consisting of boys aged eight to ten, participated in the Wisconsin General Test Apparatus in a form modified for…

A hypothesized hierarchy of tasks in the development of tactual discrimination (an essential skill for reading) was tested in 60 blind primary level children. For five braille and five Optacon (optical to tactile converter) sequences, Ss were asked to identify the different stimulus from the four presented. Scalogram analysis was used to examine…

The relationship between color cues, figure form, and size discrimination was investigated. Subjects were 28 kindergarten students selected at random from a lower socioeconomic elementary school and 28 grade-3 students from the same school. From a higher socioeconomic area school, 28 grade-3 students were selected. In addition, 12 slow readers in…
