Assignment 3: Signal Detection Theory
Signal detection theory originally grew out of the development of radar and communications technology. It was adapted by psychologists to explain certain aspects of sensation and perception processes that previous theories did not encompass. Signal detection theory models the decision-making process you would use when you want to decide between two different categories of stimuli. For example, you have to decide whether a person seen in a café (the stimulus) is a friend or a stranger (the categories).
Throughout this course, you will access a Cognitive Psychology Online Laboratory (CogLab) demonstration to explore some of the theories and processes of sensation and perception through a hands-on approach. This assignment is your first CogLab activity.
Click here to download the CogLab program.zip file to install this program. You may also download the CogLab Instructions file. After installing the program, launch it. Then, refer to the CogLab Student Manual.
Access the CogLab demonstration “Signal Detection” and follow the instructions to complete the demonstration.
Using the CogLab manual, the textbook and module readings, the Argosy University online library resources, and the Internet, research signal detection theory.
Based on the CogLab demonstration and your research, address the following:
Write a 2–3-page paper in Word format. Be sure to include a title page and a reference page. Apply APA standards to citation of sources. Use the following file naming convention: LastnameFirstInitial_M1_A3.doc. For example, if your name is John Smith, your document will be named SmithJ_M1_A3.doc.
