Pictures shown on random not seen on data log

    Pictures shown on random not seen on data log

    Hi,
    I have created a stimlist of pictures so that pictures can be shown to subjects randomly. However, on the data log file, the stimulus column is left blank. I have attached the input and data files as well as the stimlist. Please review and let me know how I should proceed. Thanks!

    Make sure you include the column headers 'stim', 'loc', and 'time' for each column that contains information.
    Also, if you go into the Log folder within the data folder, and open up 1_log.csv, can the remaining data be found here?

    Yes, Thank you! Sorry, but one other quick question...the RT (reaction time, correct?) corresponds the time that they saw the final blank screen and answered with alt or control, so what is time 4?

    The columns Time 1 through Time 4 indicate exactly how long the screens were displayed for. For instance, if Time 4 contains a value of 1200, that means that it stayed on screen for 1200 milliseconds - exactly.
