Question 1

Cross-age correlations are used to assess the stability of IQ. Research has shown that IQ is generally

Accepted Answer

A)  highly stable; cross-age correlations with adult IQ are about .70-.80 by 8 or 9 years of age. 
B)  highly stable, but only for children living in extreme environments (that is, extreme poverty or substantial wealth). 
C)  not highly stable; cross-age correlations never exceed .30-.40 when IQ is assessed over a period of two years or longer. 
D)  not highly stable; IQ is a good predictor of how a person is functioning at a specific time, but is highly variable with situations and thus produces highly different scores when given to the same person at different time, producing cross-age correlations that rarely exceed .30.

Question 3

At about 3 years of age, symbolic play increases substantially in complexity, with children engaging with other children in role-playing, called

Accepted Answer

A)  object-oriented play. 
B)  child-oriented play. 
C)  sociodramatic play. 
D)  Symbolic function.

Question 4

DeLoache and her colleagues showed children either photographs or miniature models of a room. Children were then shown, using either the photograph or the model, where a toy was hidden in the "real" room. Children then entered the real room and were asked to find the toy. DeLoache reported that the youngest children (2 year olds) were

Accepted Answer

A)  better able to solve the problem with the model than with the photographs; the greater similarity between the model and the real room made the task easier. 
B)  better able to solve the problem with the photograph than with the model; the photograph was less interesting as an object than the model, making it a more effective representational tool. 
C)  able to solve the problems with both the model and photograph equally effectively; children have implicit knowledge about object representation, which can be demonstrated as soon as they are old enough to perform the task. 
D)  unable to solve the problem with either the model or the photograph; representational insight develops slowly over the preschool years, and is not demonstrated by 2 year old children for any representational medium.

Question 5

DeLoache defined representational insight as

Accepted Answer

A)  the reliance on intuitive (or implicit) versus rational (or explicit) cognition. 
B)  the ability to represent an object simultaneously as the object itself and as a representation of something else. 
C)  the knowledge that an entity can stand for something other than itself. 
D)  the knowledge that objects have permanence even when out of one's immediate perception.
