This software creates an experiment modeled after Sternberg's short-term memory scanning task. The purpose is to study how information is retrieved from short-term memory (STM) based on the subject's reaction time.
Each experiment has multiple trials, and each trial consists of the following for each of the six number of study items:
There are a total of 11 variables which are explained below.
Choosing Experiment Variables
Number of Study Items - This will specify the number of study items that will be presented to the subject. Each trial will consist of presenting each one of the six specified number of study items. The number must be between 1 and a maximum of 1 less than the number of items in the study set. For the set of consonants, the maximum is 20.
Starting and Running the Experiment
To begin the experiment, press the Start Experiment button. The subject will be shown a "#####" before each trial. Before the test item is presented, the subject will be shown a "=====". The subject then presses the 'f' key or the 'j' key depending on whether or not they recall the test item being present in the study list.
