Infants' use of auditory information in guiding their search behavior is examined in this study. The subjects were two groups of 9-month-old crawling infants. Group 1 consisted of 24 infants and Group 2 of 16 infants. The auditory stimuli was the mother's voice. Infants in both groups were initially positioned by their mothers behind a screen in a…

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…

ONE GROUP OF 16 SS (SUBJECTS) WAS GIVEN A RANDOMIZED LIST OF WORDS THAT CONTAINED EIGHT SERIES OF FOUR ASSOCIATIVELY RELATED NOUNS, WHILE ANOTHER GROUP OF 16 SS WAS GIVEN A RANDOMIZED LIST OF WORDS THAT CONTAINED EIGHT SERIES OF FOUR ASSOCIATIVELY UNRELATED NOUNS, AND THE TASK FOR BOTH GROUPS WAS TO WRITE A STORY THAT CONTAINED THE NOUNS FROM THE…

THIS STUDY WAS CONCERNED WITH THE SYNTACTIC RELATIONSHIPS WITHIN WHICH ASSOCIATIVELY RELATED AND ASSOCIATIVELY UNRELATED NOUNS APPEAR IN SENTENCE PRODUCTIONS. TWENTY SS (SUBJECTS) WERE ASKED TO WRITE SENTENCES THAT CONTAINED FOUR NOUNS. THE HIGH ASSOCIATION (HA) SS WERE GIVEN GROUPS OF ASSOCIATIVELY RELATED NOUNS, AND THE LOW ASSOCIATION (LA) SS…

A STUDY WAS CONDUCTED TO DETERMINE HOW ADULTS ADAPT TO DIFFERENT PASSAGE ORGANIZATIONS AND STIMULI WHICH PLAY A CRITICAL ROLE IN GOVERNING READING BEHAVIOR. A MODEL OF READING IS DESCRIBED WHICH STATES THAT SUBJECTS ENTER A MINIMAL SET OF STIMULI INTO MEMORY WHICH GOVERNS SUBSEQUENT FEEDBACK CONTROL, AND THAT SUBJECTS ALLOW PASSAGE ORGANIZATION TO…

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…

This paper is concerned with two questions derived from Piaget and Inhelder's (1973) work on the relationship between memory and the developing intelligence of the child. First, can children retain operatively advanced information through the use of a non-operative mnemonic? Secondly, can the salience of operative versus non-operative information…

Frequency difference thresholds were determined for fourteen 4- to 9-month-old infants (mean age, 6 months 10 days) using a discrimination learning paradigm, following a one-up, two-down staircase procedure. The subject heard 500 msec tone bursts repeated at a rate of one per sec, with a fixed standard frequency. At various points in this pulse…

This paper points out the inadequacies of emotional or drive-based theories of exploratory behavior and offers instead a behavior analysis conceptualization. Exploratory behavior as an emotional state was rejected because the environmental conditions said to arouse exploration and the behaviors said to manifest curiosity are too general to…

This study examined the feasibility of one method of investigating the development of children's implicit awareness of syntactic patterns. An enriched version of the free association format was used to test 32 subjects. The principal variables of interest were the subject's grade level, and the syntactic pattern and meaningfulness of the semantic…

Previous research has demonstrated that requiring children to trace from memory the correct member of a pictorial discrimination pair markedly facilitates performance. The subjects for the first experiment in this study were 45 fifth grade students. The control group was given regular discrimination learning instructions. The image-trace group was…

Twenty normal newborns, approximately 36 hours old, were tested using an auditory temporal conditioning paradigm which consisted of a slow rise, 75 db tone played for five seconds every 25 seconds, ten times. Responses to the tones were measured by instantaneous, beat-to-beat heartrate; and the test trial was designated as the 2 1/2-second period…
