In an implicit memory experiment, participants are first briefly exposed to unusual, lengthy words in Phase I; later in the week, in Phase II, participants return for a word completion task, in which they attempt to fill in the missing letters of each of a list of words (e.g., p _ _ _ u d _ _ e). Some of the words correspond to Phase I words; others do not. Which pair below correctly identifies the variables of interest in this study
A)Phase I or II-independent variable; whether Phase II words had appeared in Phase I - dependent variable
B)Phase I or II-independent variable; word completion accuracy-dependent variable
C)whether Phase II words had appeared in Phase I-independent variable; Phase I or II-dependent variable
D)whether Phase II words had appeared in Phase I-independent variable; word completion accuracy-dependent variable.

The independent variable is whether the words in Phase II had appeared in Phase I, as this is the condition manipulated by the researchers. The dependent variable is the word completion accuracy, as this is the outcome being measured to see if prior exposure influences performance.
