The E-Studio interface has four major components: 1.Toolbox 2. Structure View 3. Properties Window 4. Workspace Lets look at some components E-Studio - Interface

The Toolbox contains objects that are dragged to procedural timelines. These objects are the basic building blocks of your E-Studio experiments. Lets look at some of these objects... 1

The TextDisplay allows you to specify text, such as instructions, that the subject will see during the experiment.

Similarly, the BitmapDisplay allows you to specify images that the subject will see during the experiment.

The List object allows you to define the blocks, trials, sub-trials, etc. in your experiment.

Procedure objects represent the timelines in your experiment. These procedural timelines tell the experiment what objects occur at what point.

The FeedbackDisplay allows you to specify the feedback that your subject will receive after a response. These are just some of the objects available to you in E-Studio.

The Structure View is an outline or hierarchical representation of your experiment. This window features a tree view similar to that in Windows Explorer. 2

The Properties Window lists the properties for selected objects and displays their current settings. 3

The Workspace contains the window representations of your experiment objects. An object is opened in the Workspace by double clicking the object on a procedural timeline or in the Structure View. 4

Lets build an experiment The experiment will involve presenting a series of pictures and words. Each stimulus will be preceded by a fixation cross. When the stimulus appears participants must press Z if it is an animal, and M if it is furniture. (categorization task) The experiment will involve presenting a series of pictures and words.
