In the present study, we investigated the impact of a word-problem intervention in retention and acquisition of knowledge after the intervention ended. We based analyses upon Grade 4 students experiencing mathematics difficulty (average age at pretest = 8.77) who received one of two variants of a word-problem intervention (with [n = 111] vs.…

Attempted to determine whether children from grades two and six generate inferences while they read or only later in response to tasks which require inferences. (Author/DB)

Tests semantic integration and frequency tally models of memory among 60 first-, third-, and fifth-grade children. Data from third and fifth graders show different patterns of results for regular and anomalous stories. The true-inference error rate was significantly greater than the error rates for false premise and false-inference sentences in…

Investigated the relationship between psychometrically defined brightness and cognitive development within Piaget's stage theory. Subjects were fifth- and seventh-grade boys. (SDH)

Examines the relation between children's (1) probability learning performance and a measure of their memory for items presented in a sequence and (2) probability learning and performance on a test of abstractive integration. Participating were 80 six- and seven-year-old boys and girls from both low and middle socioeconomic classes. (Author/RH)

Punisher effectiveness and generalization of an aversive stimulus, a rationale, and a combination of the two were investigated in a laboratory analog designed for punishment research, with 80 first and second grade subjects. Significantly greater suppression of deviant behavior and punishment generalization occurred when the punisher consisted of…

Investigates inferential behavior in five- and six-year-old children who made inferences about the spatial locations of models of animals and people in three experiments. Two levels of inference were found. Inferences of most five year olds were consistent with information given; Inferences of most six year olds were logically necessary ones.…

Reports three experiments based on the hypothesis that qualitative changes in verbal reasoning emerge, not from the conclusions children draw, but from what they accept as conclusive evidence. Results show a gradual development across 7-13 age range in ability to distinguish logically certain from only suggested or probabilistic conclusions.…

The role of reversibility in children's comprehension and memory for sequences of pictures was investigated for children in preschool, kindergarten, and first and second grades. Bidirectionality in the ability to remember and infer antecedents and consequences was assessed. (JMB)

This study investigated the development of the concept of a critical search area by means of an action sequence in which a cartoon character loses his toy while walking through his house. The results showed that it is not until ages 7 or 8 that children readily make the inference that the critical area is the only plausible place to search for the…

This study investigated the use of covariation as a principle of causal analysis in children 3-4, 6-7, and 9-11 years of age. The results indicated that children as young as 3 years were capable of using covariation information in their attributions of simple physical effects. (Author/CS)

Twenty children, 3-12 years old, were given a newly constructed interview on their concepts of human reproduction (social causality), in conjunction with Piaget-type tasks assessing physical conservation-identity, physical causality, and a new social identity task. The children's concepts of human reproduction appeared to proceed through a…

Children's ability to infer consequences from sentences automatically was assessed in two cued recall experiments. Seven- and eight-year-old children and adults served as subjects. (JMB)

Children, aged 4-8 were given 2-term relational problems to test the hypothesis that only older children can process sentences as propositions and realize their logical implications. Results indicated even the youngest children could perform the task. (ST)
