SO THAT TEACHERS MAY LEARN TO IDENTIFY AND CONSTRUCT BEHAVIORAL OBJECTIVES, 2 TECHNIQUES FOR DEVELOPING SLIDE-TAPES WERE COMPARED ON THE BASIS OF STRUCTURAL CHARACTERISTICS OF SLIDE-TAPES PRODUCED AND OF ACHIEVEMENT RESULTING FROM THEIR USE. THE TECHNIQUES WERE RATIONAL ANALYSIS (RA) AND SELF-SEQUENCING (SS). RATIONAL ANALYSIS OF COMPLEX TERMINAL…

THE EFFECTS OF SEMANTIC CONTEXT ON THE VERBAL REACTION TIMES OF CHILDREN READING HOMOGRAPHS WERE STUDIED BY A COMPARISON OF THE EFFECTS OF WORD OR LETTER CUES PRECEDING THE HOMOGRAPHS TO BE READ. THE INVESTIGATOR DEVISED TWO EXPERIMENTAL WORDLISTS CONTAINING HOMOGRAPHS PRECEDED BY ONE-WORD, SEMANTICALLY SIMILAR NONHOMOGRAPHS AND TWO CONTROL LISTS…

A study was conducted with three eighth grade students to determine the separate and joint effects of image size, image brightness, and image contrast on the visibility of projected materials. Twenty-five hundred slides were presented, representing 20 slides each of all possible combinations of values of the independent variables. Telegraph keys…

This report tells of the procedures and results of a psychophysical study of 28 3.8-year-old-boys from the Harlem Training Center. In spite of an experimental situation that was something of an ordeal, some meaningful data was generated. The main area investigated in this study was the evoked-response indices of temporal processing, that is, the…

Described is a study concerned with the mode of presentation of printed mathematical word problems. Tenth grade students were given twenty word problems to solve, presented in one of three ways: (1) prose only, (2) prose with an accurate picture included, or (3) prose with a distorted picture. Experimental results showed that the group with an…

Two experiments were conducted to investigate the learning and retention of concepts formed from novel visual stimulus materials (wave-form patterns). The purpose of the first experiment was to scale sets of wave forms as a function of difficulty, i.e., subjects were shown a prototype wave form and were asked to give same-different judgments for…

Today's video-oriented students know how to see, but not how to make pictures in their heads from words on a printed page. Various suggestions are offered for fostering this skill. (MJB)

The effectiveness of the separate auditory and visual components of a combined auditory-visual conjugate reinforcer was assessed in 27 3-month-old infants. (Author/SB)

Concludes that the significant difference found between responses made to displayed drawings and those made to models suggests that, independently of the complexity of stimulus, encoding will not influence responses if the very economical process of simple coding can be used. (Author/AM)

The figural simplicity or salience of parallel lines was studied in 3- and 4-year-olds by means of a figural matching procedure where parallelism was a basis for judging similarity. (Author/JMB)

This article reports two attempts to demonstrate the discrepancy hypothesis prediction that visual fixation time for human infants should be an inverted-U function of the magnitude of discrepancy between a new stimulus and a familiar standard. (Author/JMB)

Studies investigated the development of children's ability to differentiate what they see from what they know in the context of conceptual perspective taking. Two developmental levels accounted for children's performance when they were asked about a naive observer's knowledge of the identity of objects. Perspective awareness training improved…

Findings indicate that infants can detect regularity in spatiotemporal series; will develop expectancies for events in the series; and will act on the basis of those expectancies even when their actions have no effect on the stimulus events. (PCB)

Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)

Habituation to single female faces and to single geometric patterns was observed separately in two groups of infants who participated in two sessions separated by 10 days. Habituation was found to be distributed into three patterns and showed moderate but significant reliability between assessment sessions. (Author/RH)
