Range of Stimuli The Cognitive Aptitude Assessment Software allows researchers to present many different types of stimuli and records both the accuracy and speed of responding to all stimulus types. "You have unprecedented versatility in creating and running your own experiments..." University of Massachusetts Psychology Professor James M. Royer, Ph.D. of the Laboratory for the Assessment and Training of Academic Skills Text Stimulus files containing text can be created using a DOS text editor. The Designer module also enables easy control of font, font size, and text color. All of these features can also be manipulated within the same stimulus event thereby enabling, as an example, the presentation of the letters of a word in different fonts or colors. Below is an example of the CAAS screen during a pseudoword naming task.  Pictures The system presents pictures using the bitmap (BMP) format. Any image converted to a .bmp format can be presented, as well as other stimuli such as the characters of an ideographic language, hidden figure images, or exact copies of problems such as those that appear in a SAT math exam. Below is an example of the CAAS screen displaying a bitmap image that was created by scanning in a released SAT math problem.  Video The Cognitive Aptitude Assessment Software, CAAS, allows researchers to present .avi or .mpeg files to their participants and have them respond using the microphone, mouse clicks, key presses or the screen click of buttons. The Designer modules allows easy creation of all of these variations. |
