List and describe two of the three major theories of concept representation. What is the mechanism of conceptual development in each of the two theories?
What will be an ideal response?
Defining-features representations—mature concepts are represented in terms of their necessary and sufficient features, so conceptual development involves learning which features are necessary and sufficient for category membership. Probabilistic representations—concepts are united by family resemblance, not defining features, so development involves picking up on the cues and correlations between cues that signal category membership. Theory-based representations—concepts embody theoretical beliefs about the physical, psychological, and biological world, so development involves the construction of naïve theories about the causal relationship between objects; although, some proponents of this view argue that primitive theories are present from birth.
