1. Define moderate discrepancy hypothesis?
2. Identify and describe the types of educational materials the moderate-discrepancy hypothesis predicts are most likely to hold children's attention?
3. Discuss whether or not this prediction is consistent with the type of instruction that research in the sociocultural tradition has shown to be most effective?
(1) Define moderate discrepancy hypothesis.
The discrepancy hypothesis states than an organism attends and affectively responds to a new stimuli as an inverted u function of the stressful physical or conceptual discrepancy [e.g., how they are dissimilar] (McCall & McGhee, n. d). For instance, as they explain, moderate stimuli from well-familiarized stimuli receive the highest degree of attention and positive affect; whereas stimuli that are just familiar or extremely deviant from what the organism knows will receive less attention and/or less positive attention. As McCall and McGhee suggest, it could even trigger negative affective emotions. To clarify, as they explain, "Typically adults are not likely to approach or spend time examining stimuli that are thoroughly unfamiliar to them, or that they haven't experienced or understand. However, "the discrepancy hypothesis underlies good teaching, because it suggests that the effective teacher present new information that can be related to a child's experience, or more importantly ...
This solution explains the discrepancy hypothesis , and its link to learned behavior in children.
