Description of the problem: We have finished running this experiment, and have collected data for over 300 participants. The experiment consists of 10 blocks, with each block consisting of a go/no-go or approach-avoidance task, collecting response time data. For only 20 of the participants, one of the blocks does not have any reaction time data. The key.rt variable for that block is missing from the csv file. The other variables related to that keyboard component (key.corr, key.keys) are there, just the .rt variable is not. Again, this only occured for 20 participants, and only for one block of trials (either the first or second block of the experiment). Also, these were not 20 participants who took it in a row; these data files are spread out from when participants first began taking the experiment to close to the end of data collection.
Any ideas what may have caused this? Also, and more importantly, is it possible to recover RT data from .log data files?
