Data dictionary:

Group (Experimental group assignment):  - 1 = Low-expectation priming; 2 = High-expectation priming

Sex (biological sex):  - 1 = Female; 2 = Male

Education (Participant's education level):  - 1 = Less than college; 2 = Some college; 3 = College or higher

Knew_TDCS (Participant's familiarity with tDCS before the study, 'prior tDCS knowledge'):  - 1 = Yes; 2 = No; 3 = Maybe

Ethnicity (Participant's self-reported ethnicity):  - 1= Asian; 2= Caucasian; 3= Black or African-American; 4= Hispanic or Latino; 5= Native American or Alaskan Native; 6= Not Hispanic or Latino, Asian; 7= Not Hispanic or Latino, Caucasian; 8= Not Hispanic or Latino, Black or African-American; 9= Other; 10= Not Hispanic or Latino; 11= Hispanic or Latino, Caucasian; 12= Caucasian, Native Hawaiian or Pacific Islander; 13= Not Hispanic or Latino, Other.

NA = no answer

Note on 'Pre_'/'Post_'variables:

This dataset includes two columns for each dependent variable of the modified Expectation Assessment Scale (e.g., 'general_motor', 'motor_rt') indicating the measurement timing relative to the information (prime) about tDCS efficacy (informational priming):

'Pre_' variables: measurement taken before the informational priming.

'Post_' variables: measurement taken after the informational priming.
