Here is the header and first 10 lines of data from the file cleaned_small_1.csv. (The names of the variables will be read from the header line and have been shortened to a maximum of 7 characters just for legibility here.) Here's the structure: Subject: 15 subjects. Session: 2,3,5,6. The experiment contains four sessions. Session 2 and 3 are normal lexical decision task in which participants are told to distinguish between words and pseudowords. Session 5 and 6 are lexical decision with a deadline in which participants are told to make a very quick response (before 460ms). Respons: which button they pressed. Participants are instructed to press right button when they see words and press the left button when they see pseudowords. 4=right hand 5=left hand. Trial: order of stimuli presentation in each session Item: words or pseudowords presented to participants Accur: correct responses or errors Task: S=normal lexical decision D=lexical decision with a deadline Frequency: H=high frequency words L=low frequency words Pseudowords don't have this parameter. N: L=low neighbourhood size H=high neighbourhood size. LexStat: W=words P=pseudowords.
