Describes the rationale underlying as well as the major features of a computer-interactive APL program IRIS, the objective of which is to obtain an individual's simple ordering of a set of stimuli in as few paired comparison preference judgments as possible. (Author/RC)

The relationship between neonatal visual information-processing and the burst-pause pattern of nonnutritive sucking was explored. (JMB)

TWO EXPERIMENTS WERE PERFORMED TO INVESTIGATE THE EFFECT OF RELATIVE NOVELTY ON CHOICE BEHAVIOR. IN THE FIRST, 48 CHILDREN OF MEAN AGE 4.4 YEARS WERE PREEXPOSED TO 1 OF 2 SETS OF TOYS FOR 0, 1, 3, OR 5 MINUTES. EACH WAS THEN GIVEN 10 OPPORTUNITIES TO PLAY WITH 1 SET FOR 30 SECONDS. THE MEAN NUMBER OF CHOICES OF THE NOVEL SET INCREASED WITH THE…

The major purpose of this study was to ascertain whether two patterns of writing practice dictation would produce different results in the development of shorthand writing achievement of Gregg Shorthand, Diamond Jubilee. The findings indicated that the rate pattern does not appear to affect the level of achievement in writing shorthand from…

This study compared the help-eliciting capacity of 4 helping conditions. Within each condition a male confederate dropped in the path of an oncoming pedestrian either 5 books, 5 coins, a glove (unwittingly), or a book (while the confederate was on crutches). The percentage of subjects helping ranged from 3 to 100, depending on the condition. The…

Hearing-impaired 6- to 13-year-olds (N=24), trained to discriminate between two stimulus complexes differing in shape, direction, and number, were asked to discriminate between individual characteristics in all possible pair combinations. General failure to respond to all characteristics equally suggested that hearing-impaired children tend to be…

The tandem principle grows from the belief that foreign languages can be mutually supportive and informative if taught together. The pairing of French and German students for pattern practice in each other's native language is a practical application of the principle. (RS)

Investigates the effect of a recorded male human voice on neonate head, eye, mouth and crying behaviors. Vocal Stimulation enhanced head movement, eye opening, mouthing and crying and influenced hand sucking. Differences between breast fed and bottle fed babies were found for mouth orientation, hand sucking and crying. (RH)

Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

Research suggests that while information about design is a central feature of older children's artifact representations it may be less important in the artifact representations of younger children. Three experiments explore the pattern of responses that 5- and 7-year-old children generate when asked to produce multiple uses for familiar…

A PROGRAM CONSISTS OF INSTRUCTIONAL MATERIAL DESIGNED TO LEAD A PUPIL ALMOST UNAIDED AND WITHOUT ERROR TO A PRESELECTED LEVEL OF LEARNING BY WHAT AMOUNTS TO A PAVLOVIAN STIMULUS-RESPONSE-TOWARD PATTERN. BEHIND ANY PROGRAM LIES THE THEORY THAT THE MATERIAL MUST START WITH SOMETHING FAMILIAR TO THE STUDENT AND PROGRESS WITH INCREASING DIFFICULTY…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER PEOPLE CAN CHANGE THEIR PERCEPTUAL PROCESSING STRATEGIES TO INCLUDE TESTS FOR THE PRESENCE OF ONLY THOSE STIMULUS FEATURES NECESSARY FOR THE TASK AT HAND. LEARNING DURING PRACTICE AND THE EFFECT OF AGE ON THE ABILITY TO USE OPTIMAL STRATEGIES WERE INVESTIGATED. A DISJUNCTIVE REACTION TIME PROCEDURE WAS…

EXPERIMENTS WERE PERFORMED TO DETERMINED HOW MENTALLY RETARDED AND NORMAL SUBJECTS SYNTHESIZE STIMULI WITH RESPONSES. ALSO, RELATIONSHIPS AMONG THE STIMULUS SYNTHESIS PROCESS, INTELLIGENCE, AND RATE OF LEARNING WERE STUDIED. DISCRIMINATION TASKS WERE USED WHICH REQUIRED SUBJECTS, NORMAL (COLLEGE, HIGH SCHOOL, AND GRADE SCHOOL ENROLLEES) AND…
