blockFeedback attribute

The blockfeedback attribute specifies which performance feedback the subject receives at the end of the block.

Member of

<block> <defaults>

Syntax

/ blockFeedback = (metric, metric, metric, ...)

Parameters

Name Type Description
metric blockfeedbackenum
ValueDescription
correctThe percentage of correct responses in the block.
latencyThe average response time for the block in milliseconds (same as meanLatency).
meanLatencyThe average response time for the block in milliseconds (same as latency).
medianLatencyThe median response time for the block in milliseconds.
windowThe percentage of responses within the response window in the block.

Remarks

If blockfeedback is specified, an special instruction screen appears at the end of the block reporting the subject's performance. If you wish to present additional performance feedback or to customize the appearance of the feedback page, you may do so using instruction pages with variable replacement expressions for the desired performance metrics.

Examples

The following block reports the subject's average latency and percent correct once at the end.

<block myBlock>
/ trials=[1-20=noreplace(testtrials, distractortrials)]
/ blockfeedback = (meanLatency, correct)
</block>
