Psychology Research Methods: Alternate Hypotheses

Flashcards covering the definition, purpose, and specific examples of alternate and one-tailed hypotheses from the lecture notes.

Alternate hypothesis (Expected)

A prediction that the $IV$ will affect the $DV$, stating that "something will happen" instead of "nothing will happen."

One-tailed Hypothesis

A specific type of prediction that indicates the direction of an outcome, such as predicting that music will improve memory rather than just changing it.

Role of the Psychologist's Expectation

Psychologists write the alternate hypothesis because it is what they actually expect to find, and the experiment is designed to see if this prediction is supported.

Example of an Alternate Hypothesis

Participants who revise while listening to music will remember significantly more words than participants who revise in silence.
