Hi！
Dear all，
When I ran my experiment, an unexpected marker appeared. However, it was not a response marker; it was a type of marker triggered when the stimulus was presented. Therefore, I am certain it is an external problem. My code is provided below. Please help me resolve this issue.
//5 for new test
<port newtest>
/ port = LPT2
/ subport = data
/ items = ("00000101")
</port>
//6 for prac
<port prac>
/ port = LPT2
/ subport = data
/ items = ("00000110")
</port>
//7 for learning response
<port learnr>
/ port = LPT2
/ subport = data
/ items = ("00000111")
</port>
<trial prac_learning>
/ stimulustimes= [0=prac_learning, prac; 2000=white]
/ beginresponsetime = 0
/ validresponse = (parameters.key_small, parameters.key_large)
/ responsemessage = (parameters.key_small, learnr, 0)
/ responsemessage = (parameters.key_large, learnr, 0)
/ responseinterrupt = trial
/ trialduration = 2500
</trial>
<trial prac_testing>
/ stimulustimes = [0=prac_testing, prac; 2000=white, old, similar, new, testq]
/ beginresponsetime = 2000
/ validresponse = (values.key_old,values.key_similar, values.key_new)
/ responsemessage = (values.key_old, oldr, 0)
/ responsemessage = (values.key_similar, simr, 0)
/ responsemessage = (values.key_new, newr, 0)
/ responseinterrupt = immediate
/ posttrialpause = 300
</trial>
Sorry, I can’t flip this image.
