Main findings of a previous study are confirmed in that the matrix mode of representation, as actually used by Ss, again leads to significantly better performance on all problems except those where information was presented in terms of negative statements. (Authors)

Seventy-two Ss attempted to solve four "who-done-it" type deductive reasoning problems which varied in mode of representation, type of logical connective employed, and affirmative versus negative statement of information. Affirmative and conjunctive problems were solved more frequently than negative and disjunctive problems (all are defined in the…

The relationship between the development of reversible thought and performance in arithmetic equations among children was investigated. Subjects were 86 second grade boys and girls. Two reversibility tasks and 20 addition and subtraction equations were administered. Results indicated significant correlations between the two variables only among…

Examined "sentiment-override" hypothesis that couple members' cognitive/affective reactions to their partners' behaviors are insensitive to communication quality of those behaviors, and that cognitive/affective insensitivity obstructs interventions to improve communication. In 40 couples, found that only males displayed pattern of results…

An anagram task administered to high and low test-anxious subjects under varied levels of external distraction showed a significant main effect of test anxiety for the "hard" anagrams which also interacted with the subjects' sex and distraction. The effects of increments of anxiety arousal produced by distraction are discussed.…

Open-ended tasks were used to examine gender differences in complex mathematical problem solving. The results of this study suggest that, overall, males perform better than females, but the gender differences vary from task to task. A qualitative analysis of student responses to those tasks with gender differences showed that male and female…

Sex differences in speed of solving mental rotation problems were replicated but college men and women were alike in frequency of use of algorithms to solve problems. The most frequent algorithm involved encoding stimuli in working memory, mental rotation of one to orientation of the other, comparison, and response. (Author/RD)

One hundred and seven 5th-8th graders were tested on spatial rotation multiple-choice items to determine age and gender differences in spatial ability. Thirty-one of them were subsequently interviewed. They were asked to explain their reasoning when solving 4 of the tested items and a problem-solving task. Features of visual and non-visual…

The application of learned helplessness theory to achievement is discussed within the context of implications for research in learning disabilities. Finally, the similarities between helpless children and learning disabled students in terms of problems solving and attention are discussed. (Author)

Aspects of daydreaming and associated mental activity were examined for sex differences in well-educated middle class Whites aged 17 to 92 years. Females reported daydreams of a problem solving nature, and lower levels of daydreams of a sexual, bizarre-improbable, heroic and achievement-oriented nature. Daydreaming contents decreased with age.…

Examined selected problem-solving behaviors of school-age children and their parents in dyadic and triadic contexts. Parent-child interactions revealed sex-of-parent and sex-of-child differences as a function of problem-solving contexts. (Author/BB)
