E. between ages of 6 and 9 years of age). The fact that conservation was observed at higher rates among males, that non-conservation was observed at higher rates among females, and that transitional rates were roughly equal suggests that males achieve conservation earlier than females in general. Implications The implications of this research are that the most relevant age range for pinpointing the most common age of achievement of conservation is between

39). However, because of translating different cultural concepts, cross-cultural studies such as those of the Baka can prove problematic: "How can one know whether similar behaviors have similar meaning across cultures capacity," when designing experiments? (Gauvain 1998, p.40). It is particularly difficult to elicit responses regarding what a subject things 'another' feels. Thus cross-cultural definitions of a theory of mind are difficult to determine, given that the child's experience is

Developmental Psychology and Theories Developmental Psychologist and Theories Piaget's cognitive theory of development Jean Piaget developed the theory of cognitive development, which suggests there are four key stages through which children advance as their minds develop. The theory focuses largely on an understanding of the nature of knowledge and intelligence, and how they acquire and use it. Piaget lays the claim that cognitive development is key to human development and that language skills

Human infants are perceptually competent hence; infants use senses mostly in everything. Moreover, learning has a lot of effect on children's decision-making. Researchers divide children's development into three: cognitive, language, and physical. All these relate to contribute to the kids general development. Cognitive development entails the need for a better means of speech that will help in expressing knowledge. Language helps a child to capture new words and ideas. Physical
