[open] [avg_rt] and [acc] undefined

Hansika

Hello,

I'm trying to run a simple experiment with the extended template, but am facing two issues:

1. I'm trying to give a positive and negative feedback using the smiley and frowny faces for now. When I enable auto response, this happens properly; but when I run it myself, all responses are given feedback with the frowny face. I've checked and changed the correct_response several times, but it hasn't helped.

2. In both cases (auto and manual), the avg_rt and acc are undefined. I've moved around the reset_feedback item too, but it hasn't helped.

I'm using a Windows 7 OS; please help!

Here's the script:

set flush_keyboard "yes"
set description "A single trial"
run fixation_dot "always"
run trial "always"
run keyboard_response "always"
run feedback_smile "[correct] = 1"
run feedback_frowney "[correct] = 0"
run __reset_feedback "always"
run logger "always"

Hi,

My first guess would be that the correct response has been specified incorrectly, but you say you have checked this. Could you perhaps post the script of the experiment, rather than just the snippet for the sequence as you have done know?

Thanks,

Edwin
