THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE RELATIVE INFLUENCE OF FIVE VARIABLES (INITIAL INSTRUCTIONS, REWARD, LETTER SIZE, TYPE OF WARM-UP, AND FEEDBACK) ON KINDERGARTEN CHILDREN'S PERFORMANCE OF A LETTER DISCRIMINATION TASK. IT HAS BEEN ARGUED THAT ATTENTION IS THE KEY FACTOR IN LETTER DISCRIMINATION. THE PRESENT STUDY PROPOSES THAT A…

This study attempted to determine the functional components of rehearsal strategies in children's discrimination learning. When a discrimination list was given without rehearsal instructions, ability to discriminate situational frequencies predicted performance. Without rehearsal strategy, subjects' ability to discriminate between previous usage…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

Eighty-four nine year old children, twelve in each of seven experimental groups, learned a two-choice successive discrimination problem. The parameters that were systematically manipulated included: (1) immediate versus delayed reinforcement; and (2) forced preresponse stimulus exposure versus stimulus exposure during the delay interval,…

Data were discussed in terms of an outline of an empirically based theory of transfer. (Authors)

A surprising validation of expectation experienced during a recognition test induces the perception of discrepancy and a feeling of familiarity. The authors investigated whether that perception also affects memory performance when it is experienced in the original encounter with a stimulus. Target words were presented in a study phase, half in…
