Piaget's theory of space perception is presented in the format of a hypothetico-deductive system. Eleven hypotheses regarding infants' space perception are defined, and Piaget's evidence for each is summarized. Presuppositions underlying the arguments are explicated. Critical notes are inserted and general conclusions are briefly discussed.…

Evidence is provided to refute the suggestion, made by Macnamara et al. (1976), that four-year-old children perform logical operations corresponding to formal logic upon the sentential components of implicative verbs to produce indirect implications. It is argued that children use past knowledge plus additional premises to derive indirect…

Presents a rebuttal to Hidi and Hildyard's (1976) criticism of Macnamara et al.'s (1976) assertion regarding the ability of four-year-old children to grasp implicatives and presuppositions. (AM)

Reports three experiments demonstrating that recall for words increases with deeper levels of processing and with longer rehearsal intervals. Asserts that there is no interaction between those strategies. (PMJ)

Investigates factors affecting students' ability to consistently apply the concept of adaptations. Individual interviews were conducted with 74 Year 10 students in Australia, of whom only 47% showed an understanding of the concept. It was found that the students were more likely to apply the concept to vertebrates. (AIM)

Presents a qualitative analysis of a transcript of a critical-thinking reading lesson designed for sixth grade students. The analysis illustrates the relationship between critical thinking and reading comprehension and demonstrates that critical thinking can be promoted in everyday classroom instruction using regular classroom materials. (JD)

A study comparing 65 deaf and hearing Australian children, aged 7-13, found that deaf subjects were delayed in number and liquid conservation, but equally mature in justice reasoning. Deaf subjects were less likely to disagree with a reward allocation proposed by an adult and to make cognitive progress when encountering conflict. (Author/JDD)

Argues that the syntactic and mental model accounts of the suppression effect in deductive reasoning are inadequate. Proposes a relative salience model. Describes a test of predictions from this model in a suppression model, which obtained evidence of convergent validity for the salience construct. Results could not be reconciled with either the…

Three experiments with 276 college, secondary, and middle-school students extend the research of G. T. Fong and others in teaching students abstract rules. Results support a revival of formalist views of transfer: that teaching formal rules about inference making can improve reasoning and support transfer. (SLD)

Concepts from cognitive psychology are presented as an alternative framework to arithmetic instruction for students with disabilities. The approach, which emphasizes reasoning, communication, and problem solving, is applied to addition, division, multiplication, subtraction, and word problems. The purpose of arithmetic instruction is asserted to…

Longitudinal data on conversations recorded from 1 child between 18 and 27 months of age and 3 children between 27 and 62 months were analyzed to chart acquisition of the word "if" and of conditional inference. Within six months of speaking their first "if," children produced "ifs" at the same rate and forms as…

Effects of undergraduate training on inductive reasoning and logic were examined. Social science training produced significant effects on statistical and methodological reasoning. Natural science and humanities training produced significant effects on conditional logic reasoning. Results indicate that reasoning is taught and generalizable. (BC)

A study with 57 second graders identified some logically irrelevant transformations that children considered relevant in relation to the weight of an object. Two logically relevant transformations, movement upward and movement downward, were irrelevant to the subjects, whether texture, continuity, temperature, and darkness were generally…

Because traditional instruction ignores students' personal construction of mathematical meaning, mathematical thought development is not properly nurtured. Several issues must be addressed, including adults' ignorance of math- and student-learning processes, identification of math-education research specialists, the myth of coverage, testing…

A qualitative approach was used to examine the cognitive processes students engaged in while playing recreational computer games. Participants were 21 high school students. Results indicated that players practiced complex cognitive processes such as interpreting explicit and implicit information, inductive reasoning, metacognitive analysis, and…
