Children aged 3 to 8 years old and adults were tested on a reality–fantasy distinction task. They had to judge whether particular entities were real or fantastical, and response times were collected. We further manipulated whether the entity is a specific character or a generic fantastical entity. The results indicate that children, unlike adults,…

We investigated the influence of speaker certainty on 156 four-year-old children's sensitivity to generic and nongeneric statements. An inductive inference task was implemented, in which a speaker described a nonobvious property of a novel creature using either a generic or a nongeneric statement. The speaker appeared to be confident, neutral, or…

This study sought to determine the accuracy of an assessment format in which selection outcomes were delayed and probabilistic; these are unavoidable features of an assessment designed to determine preferences of multiple children simultaneously. During the single arrangement, preference hierarchies were established by having a child repeatedly…

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…

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…

Signal detection theory as a framework for interpreting concept acquisition was studied in three experiments involving preschool children. Results of the studies suggest that juxtaposition of minimally different examples is superior to exclusively positive sequences, and consistent instructions are superior to varied instructions. (Author/JN)

The purpose of this study was to measure nonverbally the preference of alternative responses when the net probability of being rewarded was the same. A demonstration of preference under these circumstances would suggest the ability to control or maintain behavior without explicit administration of a reinforcing agent. Head Start children were used…

Three studies explored children's distinctions between mental and bodily reactions to contamination. Found that children distinguished reactions mediated by representations from those mediated by physical interactions. Data suggested that preschoolers distinguished between physical and mental reactions to contamination but had a poor understanding…

Discrimination learning set performance was examined in preschool children as a function of age and number of trials per problem. Subjects were 120 children three, four, five, and six years old. (MP)

Argues that first language acquisition is essentially based on a process very similar to classical conditioning. (TO)

One of the focal points of this study is the investigation of the relationship between rates and types of imitative responding and responsiveness to social reinforcement (approval). Subjects were 96 children (5 to 6 years old) equally divided according to sex and race (Negro and white). Findings indicate that: (1) it seems tenable to assume that a…

A mathematics unit which introduces number concepts through the use of patterns. All activities are based on the formation of patterns involving blocks or tiles of two colors. (RP)

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

A STUDY BY TABER AND GLASER WHICH TAUGHT SIGHT VOCABULARY BY THE VANISHING LITERAL PROMPTS METHOD WAS REPLICATED IN AN EXPERIMENT WITH 14 PRESCHOOL, KINDERGARTEN, AND BEGINNING FIRST-GRADE CHILDREN. MATERIALS USED WERE EIGHT LOWER CASE COLOR WORDS PRINTED ON 3 BY 5 CARDS. AFTER PRETESTS TO IDENTIFY COLOR KNOWLEDGE AND CONFIRM LACK OF WORD…
