Data and Analysis Unit: KULMAES2

Last update: 2015-05-15 by Andy Wills

Description

Human discrimination task, reported as Experiment 1B in Maes et al. This DAU contains stimuli, trial-level raw data, and an analysis script, all in open cross-platform formats (see the file format notes). It also provides some informal resources for running experiments like this within the experiment generator Affect 4.0.

UPDATE: The sex, age, course, and year columns of kulmaes2data.txt have had all their data replaced with the word 'deleted'. This is in response to concerns about the potential non-anonymity of biographical data when pooled. All queries regarding these columns should be directed to Elisa Maes or Tom Beckers.

- subj: Participant ID (unique within KULMAES2)
- cbal: Stimulus counterbalance condition, as described in kulmaes2cbal.txt
- sex, age, course, year: Deleted for confidentiality
- phase: Experiment phase.
- block: Experimental block (Does *not* reset between phases)
- trial: Experimental trial (*DOES* reset between blocks)
- stim: presented stimulus, coded in terms of the abstract design.
- rein: Reinforcement (1 = reinforced, 0 = nonreinforced)
- score: Total number of points scored (resets after practice phase, but nowhere else)
- totresp: Total number of responses made (resets after practice phase, but nowhere else)

- resp: Number of responses during the trial.
kulmaes2cbal.txt (1 KB) - Stimulus counterbalancing. Column heading as as follows:
- cbal: Counterbalance condition, see above.
- A-F: The abstract stimulus type, see above. For each combination of abstract stimulus and counterbalance condition, the table specifies the physical stimulus employed. The six physical stimulus types are provided in this DAU.
