Twelve 21/2-year-old children received adult verbal intervention selectively directed toward acquisition of either question forms or verb forms. Findings showed that children who received verb intervention acquired new verb structures while children who received question intervention acquired new forms of questions. (Author/JMB)

Examined relationships among word comprehension, word production, and enactive and gestural naming by 136 infants of 12-16 months. Results indicate that infants can use adult speech as an aid in the reproduction of modeled gestures. (RJC)

The verbal interactions of 20 mothers with their children, who were between 1.9 and 5.0 years old, were recorded and analyzed. (SB)

Studies show many experts believe that there is no significant difference between the age when a boy begins to communicate verbally and when a girl begins. (SW)

In Skinner's analysis of verbal behavior, three categories of environmental control over instances of verbal behavior appear to be relevant to the study of infant vocal development: the mand, the tact, and the echoic categories. Procedures used in the remediation of language deficiencies and procedures found in work in the area of language…

To the question of whether Chomsky's hypothesized Language Acquisition Device (LAD) in young children is an adequate and feasible model of language acquisition, this paper answers that LAD should be reformulated so as to include semantics; that "informant presentation" rather than "text presentation" is responsible for language…

Study examined speech complexity among 22 sets of parents and their school-age children during two time periods approximately one year apart. Parents and children were videotaped while completing a block design task and their conversations were transcribed. Speech patterns were found to differ at the two times. (Author/BN)

Examined the relationship between infants' early verbal imitation, when the ability to copy behaviors first emerges, and their lexical development during the second year of life. Twenty infants were examined longitudinally at ages 10, 13, 17, and 21 months. Suggests that infants' early imitation of words not in their repertoires predicts and may…

FIVE STUDIES ARE REPORTED OF OPERANT CONDITIONING AND LANGUAGE DEVELOPMENT PRINCIPLES IN READING. THE FIRST STUDY OUTLINED THE RATIONALE AND PRINCIPLES UNDERLYING THE PROJECT. THE SECOND STUDY INITIATED AND REFINED APPLICATIONS OF REINFORCEMENT PROCEDURES FOR STUDYING EFFECTS OF DISCRIMINATION TRAINING ON READING. STUDY NUMBER THREE DEMONSTRATED…

A study was conducted to determine criteria to measure successful language development and to determine what factors might be considered to be the determiners of this development. Subjects were 16 children, aged 3 years 3 months, selected on an intuitive basis from the 64 children in the older age group to represent the full range of development,…

The speech of two mothers to their infants between three and eighteen months was analyzed. Simplicity of speech was about the same at all ages, not showing abrupt change as children began to talk. It is suggested that mothers used a conversational model and changes reflect children's growing conversational ability. (CHK)

This research review sought to discover the forms of family verbal interaction that nurture language development in infants and toddlers, the function of different family members in this process, and the role of environmental factors in language development. Results indicate that speech to a child is significantly different from speech to an…

This bibliography on the acquisition and development of speech and language lists, in alphabetical order by author, 423 books and journal articles published between 1937 and 1970. [Not available in hard copy due to marginal legibility of original document.] (DD)

Offers some conversational suggestions (modeled on a typical day in the life of the preschool) intended to motivate children to communicate and to build a better relationship between pupil and teacher. (Author/ED)

This paper provides a brief outline of some of the constituents of speech, language, and universal stages of the development of talking in children up to the age of 2 1/2 years. Mention is made of theories put forward to account for universal aspects of speech and language development; recent research into the way adults talk to very small…
