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

<expressions>
/ feedbackmsg = if (block.example.percentcorrect < 75) {
    "Try to make fewer errors!"
    } else if (block.example.percentcorrect > 95) {
        "You're doing great!"
    }
</expressions>

<page feedbackpage>
^You responded correctly in <%block.example.percentcorrect%>% of trials.
^^<%expressions.feedbackmsg%>
</page>

<block example>
/ postinstructions = (feedbackpage)
/ trials = [1-100 = noreplace(a, b)]
</block>

<trial a>
/ stimulusframes = [1=atxt]
/ validresponse = ("a", "b")
/ correctresponse = ("a")
</trial>

<trial b>
/ stimulusframes = [1=btxt]
/ validresponse = ("a", "b")
/ correctresponse = ("b")
</trial>

<text atxt>
/ items = ("A")
</text>

<text btxt>
/ items = ("B")
</text>
