Exercise 1 Implement Basic Experiment

(A list of stimuli and expected responses, a procedure for the task that includes responses, a procedure for the task that includes a presenting a fixation and a stimulus.) a presenting a fixation and a stimulus.)

The goal is to learn to use the E-Studio interface The goal is to learn to use the E-Studio interface and to learn to implement the basic structure of and to learn to implement the basic structure of an experiment. an experiment.


Exercise 1: Conceptualize and implement the core experimental procedure

Sample AbstractThe experiment will measure the time it takes to make a lexical decision. The independent variable is whether a letter string is a word or non-word. The stimuli will be text strings of words and non-words, presented in random order in black text on a white background. The subject will be presented with a fixation (+) displayed in the center of the screen for one second. Then a probe display will present a letter string stimulus in the center of the screen for up to 2 seconds. The stimulus display will terminate when the subject responds. Subjects are to respond as quickly as possible whether the stimulus was a word or a non-word by pressing the “1” or “2” key respectively. The dependent measures are the response (i.e., key pressed), response time, and response accuracy of the probe display.

Exercise 3 Nested ListExercise 3 Nested List

In many experiments you want to choose stimuli from a In many experiments you want to choose stimuli from a list (e.g. a list of verbs). E-Prime allows you to specify list (e.g. a list of verbs). E-Prime allows you to specify a list of stimuli to use in different conditions. The list a list of stimuli to use in different conditions. The list items can be chosen in a different order than the list of items can be chosen in a different order than the list of trials (e.g., alternate trials of words and non-words but trials (e.g., alternate trials of words and non-words but select particular words/non-words in sequential order). select particular words/non-words in sequential order).

How Nested Lists WorkHow Nested Lists WorkWhen there is a list name in the Nested column, the program goes to When there is a list name in the Nested column, the program goes to

that list, samples a list from that row setting the attributes from that that list, samples a list from that row setting the attributes from that row based on the sampling method of the list, and then continues to row based on the sampling method of the list, and then continues to fill in the rest of the attributes in a left to right manner. In Row 1, fill in the rest of the attributes in a left to right manner. In Row 1, the Word list would be sampled, the attribute (Stimulus) would be the Word list would be sampled, the attribute (Stimulus) would be set and then the other attributes of the row would be set and the set and then the other attributes of the row would be set and the procedure (TrialProc) would be executed. procedure (TrialProc) would be executed.

Note the sampling of the nested and design list can be different (e.g., Note the sampling of the nested and design list can be different (e.g., sample conditions randomly and words sequentially). Also you sample conditions randomly and words sequentially).
