This experiment shows images in two conditions, e.g., hard and easy, or emotional and neutral. The file condition1.txt contains the exact names (with extension) of the images for this condition you have uploaded. The must be comma-delimited, e.g., image1_1.jpg, image1_2.jpg, etc. Similarly for condition 2. You can also upload a second mask (for condition 2) by updating the masks.txt file.

So called DRM paradigm experiment. A critical lure 'sleep' is used as a base. Several associated words are derived from that, called targets. These are shown to the subject. Then these are mixed with words not seen before and with the critical lure. For each of these, the subject has to indicate whether were presented before or not. A typical finding is that many people mistakingly believe that have seen the critical lure earlier, when in fact it was not presented before.
