LINGUISTIC AWARENESS AND EARLY READING

Children from five Year 1 classes (n = 129) were assessed with the Concepts About Print (CAP) Test and standardized reading measures. A principal component score derived from the South‐gate Word Selection Test and the ACER Primary Reading Survey Test Level AA was used to derive three groups of readers (poor, average, good). A factor analysis of the CAP indicated four clusters of items. Three of these, letter‐word concepts (.77), print direction concepts (.39) and age (.32), were found to load on a significant discriminant function separating the three groups. Univariate procedures revealed that print direction concepts, letter‐word concepts and advanced print concepts significantly separated the three groups of readers but book orientation did not. Results were discussed in relation to the validity and reliability of the CAP, the relevance of linguistic awareness skills to early reading and the need to tie instruction to concept learning.     

Evolution of Primate Cognition

Comparative analysis of the behavior of modern primates, in conjunction with an accurate phylogenetic tree of relatedness, has the power to chart the early history of human cognitive evolution. Adaptive cognitive changes along this path occurred, it is believed, in response to various forms of complexity; to some extent, theories that relate particular challenges to cognitive adaptations can also be tested against comparative data on primate ecology and behavior. This paper explains the procedures by which data are employed, and uses the best currently available evidence to derive a proposal for some of the stages through which human cognition evolved, before the last common ancestor with a nonhuman, and the reasons that cognitive adaptations were favored in primate evolution.     

Mental cookery: An illustration of fact retrieval from plans

Anyone who is able to cook a certain dish will probably also be able to list its ingredients from memory. Detailed recording of this verbal listing exposes structural regularities. These imply that people can search a representation which is essentially the same as that used in the actual cooking. In effect, the dish can be “mentally cooked” and the necessary ingredients reported when they occur. This ability to mentally simulate plans allows considerable cognitive economy.
