Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted--for example, that rain exists for plants to grow. Five experiments explore…

In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

This study aims to contribute to a better understanding of the antecedents and effects of educational leadership, and of the influence of the principal's leadership on intervening and outcome variables. A path analysis was conducted to test and validate a causal model. The results show no direct or indirect effects of educational leadership on…

A study was conducted of differences in processing speed and recall with 61 10th-grade biology students studying a unit on plants and controls who took only the unit tests. Processing speed and recall improved as much for students completing the unit as for controls. (SLD)

Suicide is analyzed as a motivation to escape from adversive self-awareness. The causal chain is traced from initial failures that are attributed internally because of a cognitively deconstructed state. (SLD)

Discusses Lawrence A. Hirschfeld's (1995) experiments, which Hirschfeld claims demonstrate that preschoolers use a biologically grounded theory in reasoning about race. Argues that the methods used cannot address the issue and therefore, the results do not support Hirschfeld's claims. Maintains that the experiments fail to demonstrate that 4- and…

Responds to John J. Kim's critique of his studies of preschoolers' understanding of race. Maintains that his and others' investigations demonstrate that preschoolers differentiate the pattern of causal reasoning governing transmission and maintenance of racial characteristics from that governing transmission and maintenance of perceptually similar…

Examines comprehension of causal text sequences (in simulation) using construction-integration analysis. States that 16 preliminary simulations, applied to 2 text frames each, influenced decisions concerning 4 simulation choice points. Reveals good qualitative fit between the construction-integration activation of the probe questions and their…

Three hypotheses accounting for individual differences in spatial visualization ability were investigated in 2 experiments with 142 male undergraduates at Georgia Institute of Technology (Atlanta). Support was found for the preservation-under-transformation hypothesis, suggesting that effectiveness of storage during concurrent information…

The literature on human aggression is large and diverse. Some of it is theory-driven, but much of it dwells on solving social problems rather than on building general models and research paradigms. This paper examines some of the research programs and theoretical emphases in aggression research and presents theory convergences to see how these…

The hypothesis that gains in reading performance occurring among dyslexic children during individually paced reading are partially attributable to changes in short-term memory processing was tested with 23 elementary school students. Findings provide support for a causal role for short-term memory functioning in text processing. (SLD)

A putative causal relationship of cognitions to affects in different phases of teachers' stress cycles was studied for 414 elementary school teachers in Finland. Results provide only negligible support for the causal predominance of cognitions in disturbed affects; the opposite seemed to prevail. Implications for teacher satisfaction are…

Tests the hypothesis that two general developmentally-based levels of hypothesis-testing skills exist. Finds a positive relationship between level of hypothesis-testing skill and performance on a transfer problem involving the test of a hypothesis based on unobservable entities. Also finds a positive relationship between level of…

Uses clinical case studies showing autistic children's fascination with and understanding of machines, family studies focusing on occupations of fathers and grandfathers of children with autism or Asperger Syndrome, and experimental evidence using picture-sequencing methods to identify physical or intentional causality to show that children with…

In Dodge's model of "social information processing" depression is the result of a linear sequence of five stages of information processing ("Annu Rev Psychol" 44: 559-584, 1993). These stages follow a person's reaction to situational stimuli, such that each stage of information processing mediates the relationship between earlier and later stages.…
