Stimuli

Task

Participants were instructed to:

  • Multiply first 3 numbers (in white) in head

  • Look at the answer (in blue) until it turned green

  • Decide if the answer is correct/incorrect when the number turns green

  • Indicate how certain they were

Study

  • 156 items per half in three conditions

    • Correct Product

    • Incorrect Product: not related to the problem in any way

    • Related Product: created by adding 1 two or 3 to one of the operands.

  • All math problems used operands 1-9, and did not require knowledge of times tables past 9x9

  • In between the two halves, a questionnaire was given to try to induce a stereotype threat through making the participants think about how much anxiety math gives them.

  • Neuropsych tests were given after the EEG data were collected
