This study examines progression trends of Chinese students' scientific reasoning skills across grade levels from elementary school to university. A large-scale survey using the Classroom Test of Scientific Reasoning (CTSR) was conducted with 2669 Chinese students at 13 grade levels (grades 4-16). The construct validity of the CTSR was first…

Information flows continuously in the environment. As we attempt to do something, our senses receive large volumes of information. In any conversation, messages are exchanged rapidly. To understand meaning, we have to focus, record, choose and process relevant information at every moment, before it is displaced by other information. Often,…

Analogous thinking has been commonly discussed as being an inherent and distinguishing characteristic of human cognition (e.g., Gentner, 2010; Goldstone, Day, & Son, 2010; Holyoak, in press; Rittle-Johnson & Star, in press). Gentner (2003) has argued that as part of the human cognitive toolbox, comparison accompanied by the relational language to…

Five experiments were performed in the area of children's causal reasoning to validate a previously reported developmental difference, to examine the role of a possible mediating mechanism, and to test a number of competing theoretical interpretations. (GO)

Syllogisms with missing conclusions, missing minor and major premises, as well as missing negative conclusion and missing conclusion to a class chain, were given to 160 gifted children (20 each from ages 4-11) to investigate the order of difficulty of certain principles of logic and the age at which these principles are acquired. (MP)

This study assessed the influence of age and ability on linear syllogistic reasoning in early adolescence by presenting bright and average 11- and 13-year-olds with 64, 3-term series problems. Results showed a dramatic effect on performance due to ability. Age effect was only marginally significant. (JMB)

A study investigating developmental differences in the ability to reason with conditional propositions used five variations of Wason's selection task to assess conditional reasoning in 132 eighth, tenth, and twelfth grade adolescents. In addition to examining developmental differences, the study had as an objective to examine the role of semantic…

Three paper-and-pencil formal operations tests were administered to groups of eighth graders and adults. These measures provided scores that indicated each subject's level of reasoning for three second-order operations: combinations, proportionality, and propositional logic. (JMB)

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.…

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…

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)

Two studies with first- and fifth-grade children in two learning tasks showed that preoperational children did not necessarily learn responses followed by a stimulus object previously instrumental in obtaining a reward, while postoperational subjects did. (Author/JMB)

A 16-item conditional reasoning test was given to 281 students in grades 8, 10, 12, and 14. Developmental patterns of performance were examined. (Author/JMB)

Children and undergraduate students were studied to expose "structure-neutral" interpretations of logical propositions involving universal affirmatives. Successes with true and false questions and with four different syllogistic forms having three content types were compared. Age-related differences in performance were discussed with…
