Description Usage Format Note

Description

A dataset containing response times and choice data for 25 subjects who completed a word identification task with immediate word priming. Subjects completed both a two-alternative forced-choice task and a same-different task, alternating between tasks every 80 blocks. Response times faster than 200 ms and slower than 4 seconds have been trimmed.

Format

A data frame with 31879 rows and 5 variables:

Subject

The index number for the 25 subjects.

Accuracy

An incorrect response is 0, a correct response is 1.

Choice

Coded as 0 if the subject picked left/same and coded 1 if the subject picked right/different.

RT

The duration from the time at which the on-screen choice alternatives were displayed and a subject's choice, in seconds.

Condition

The index number for the current condition (see notes).

Note

The conditions of the experiment are provided in the following table. The first column gives the index number. The second column indicates the type of task, where 2AFC refers to the two-alternative forced-choice task, and SD refers to the same-different task. Column three reports whether the target word or a foil word was primed. Column four indicates the duration in ms for the prime word. Column five indicates the type of correct response where L denotes left, R denotes right, S denotes same, and D denotes different.
