In splithalfr: Estimate Split-Half Reliabilities

Example Implicit Association Task (IAT) Data in JASMIN2 Format

Description

The JASMIN2 IAT closely followed the original IAT procedure (Greenwald, McGhee, & Schwartz, 1998), except that target and attribute trials did not alternate. Upon a correct response, the next trial started. Upon an incorrect response, the current trial was repeated. The response to each trial was logged. This particular dataset is from a Ethnicity-Valence IAT, which was administered (and described in detail) in \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/j.tate.2019.102887")}Abacioglu and colleagues (2019). This dataset was graciously provided by Fadie Hanna and Marjolein Zee.

Usage

ds_iat

Format

An object of class data.frame with 9696 rows and 11 columns.

Details

Overview of columns:

• participation_id Identifies participants

• t1_left. If TRUE, the first combination block had target 1 on the left (and target 2 on the right)

• a1_left. If TRUE, the first combination block had attribute 1 on the left (and attribute 2 on the right)

• block_type. Type of block

• block. Counts blocks, starting at zero

• trial. Counts trials in blocks, starting at zero

• attempt. Counts attempts (responses) in trials, starting at zero

• cat. Category that stimulus belonged to

• stim. Stimulus

• response. Response; 1 = correct, 2 = incorrect, 3 = timeout (no response in 4000 ms), 4 = invalid key

• rt. Response time in milliseconds. Note that some response times may exceed the timeout window due to clock errors on the computer that the IAT was administered

The variable block_type can have these values:

• tar_discr: target discrimination

• att_discr: attribute discrimination

• tar1att1_1: target 1 with attitude 1, practice block

• tar1att1_2: target 1 with attitude 1, test block

• tar_rev: reverse target discrimination

• tar1att2_1: target 1 with attitude 2, practice block

• tar1att2_2: target 1 with attitude 2, test block
