Scripts and Stimuli
In the MAP Lab, we write scripts in MATLAB (The MathWorks, Natick, MA). The scripts posted below were written by and are the property of Scott D. Slotnick (or Lauren R. Moo, as specified). They are not to be used for financial gain, but rather are for open use by the fMRI and ERP community (use them at your own risk). If you find a bug, email email@example.com. Type 'help script_name' (without the single quotes or .m) on the MATLAB command line to display basic script functionality and format.
Stimulus materials are also included on this page (see below). These stimuli were constructed by Scott D. Slotnick and the associated manuscript should be referenced if they are used for publication.

Abstract shapes designed to limit verbal processing. There are 6 lists of 48 shapes (148, 5198, 101148, 151198, 201248, 251298), where the prototype shape is labeled E0, the studied exemplars are labeled E1E9, and the nonstudied exemplar is labeled E10. For a detailed description, see Slotnick and Schacter (2004) and the Supplement.
