The Premack principle and the disequilibrium principle both deal with

A) whether or not something will be an effective reinforcer.
B) how we come to see an overall pattern from an assortment of visual stimuli.
C) whether we make internal or external attributions in a given situation.
D) our motivation to resolve cognitive dissonance.

Premack Principle

A psychological principle stating that more probable behaviors will reinforce less probable behaviors, suggesting that if a person wants to perform a less desired activity, it can be motivated by the promise of a more desired activity.

Disequilibrium Principle

A concept in developmental psychology suggesting that cognitive growth occurs through processes of assimilation and accommodation, driven by experiences of imbalance or disequilibrium.

Effective Reinforcer

A stimulus that, when presented after a behavior, significantly increases the likelihood of that behavior occurring again in the future.
