## Give feedback after a block of trials depending on percent correct responses

 By Diane - 5/12/2023 Hi, How can I give feedback at the end of a block of trials that depends on the percent correct responses. For example, if the percent is < 75% the feedback is "Try to make fewer errors" and if the percent is > 95% the feedback is "You're doing great!"Thanks!Diane By Dave - 5/12/2023 +x Diane - 5/12/2023Hi, How can I give feedback at the end of a block of trials that depends on the percent correct responses.
