Seven-year-olds and university students were questioned about hidden or visible colored counters. Under certain testing conditions, the children were able to demonstrate one of the major characteristics of formal operational thought, namely the ability to reason in terms of verbally stated hypotheses without reliance on direct, physical…

Two studies examined the effects of different types of imaginal elaborations on recall. In Experiment 1, 6-year-olds, 9-year-olds, and college adults were given 20 word pairs embedded in one of four types of sentences: short plausible, bizarre, personalized, or self-generated. With no mention of a memory test, subjects were asked to use the…

Results of five experiments showed that in certain situations recall varied with processing difficulty for both children and college students. This was primarily due to enhanced cue discriminability. The relation between processing difficulty and developmental increases in recall seemed to be mediated by constructability problems and resource- and…

Adverse effects of material rewards on Wechsler subscale performance may be the result of a reward-produced developmental regression. To further explore that idea through replicating earlier findings with adults, and to extend the enquiry to children, selected Wechsler subscales were administered to 32 subjects at each of three ages (5, 10, and 18…

Four studies examined developmental differences in the representation of basic-subordinate inclusion relationships in three-, five-, and seven-year olds and undergraduates. Found that even three-year olds showed rudimentary knowledge of the asymmetry of inclusion. There was a marked developmental gap between producing subordinate category names…

An exploration of the linguistic patterns and conversational strategies of adult learners was conducted to clarify the relationship between individuals' oral communicative ability and their levels of proficiency in the nonoral literate modes of reading and writing. The connection between social class and language development was also examined.…

This study was designed to determine what happens to the intelligence quotient of freshman students during their enrollment at a private Negro college. The Otis Quick-Scoring Mental Ability Test, Gamma Em, was administered to 822 students from a population of approximately 2,000 in their freshman year at Hampton Institue, Hampton, Virginia. The…

Second graders, fifth graders, and college students heard 12 stories that varied systematically by situational domain, outcome, and causal attribution. Students were asked to infer the story character's emotion at the end of the story and give reasons for it. Contributions and limitations of Weiner's attribution-emotion model are assessed in light…

This research contrasts the learning effects of an affective dimension of meaningfulness with the word-quality of consonant-vowel-consonant trigrams. Subject rated trigrams for both "association value"--having word-quality versus lacking word-quality--and "reinforcement value"--liking versus disliking the trigram regardless of word quality. Paired…
