Exam 2: Research Methods

Which of the following is NOT characteristic of the method of adjustment?

In performing a listening task, Tracey incorrectly reports hearing a tone when none was present. When asked why she did that, she said, "I know I heard something on the first 7 trials, so surely there was a tone on trial 8, too. i. Tracey has made an:

The equation, S = k log I represents:

Cara has just finished eating a huge piece of sweet chocolate cake. She is then asked to participate in a taste-test to determine whether she can detect small amounts of sugar added to water. She is likely to have:

On a trial in which only noise is present and no target stimulus, John responds, "No, I didn't hear anything." John has made:

The graph below shows the results for a participant when discriminating whether a line is greater than 5 inches. -The lower difference threshold is:

Each separate ROC curve represents a different: (p. 33)

The equation, represents:

The graph below shows the results for a participant when discriminating whether a line is greater than 5 inches. -The point of subjective equality is:

In an experiment, participants are asked to describe how intense the feeling of cold is when placing their hand in ice water by adjusting the lighting in the room to match. This is an example of:

The absolute threshold is defined as the smallest intensity required for the stimulus to be reported:

A two-alternative forced choice procedure minimizes:

Kyle performs a detection task in which he is asked to determine whether or not the letter T appears on a checkered screen. The table below shows the possible outcomes based on his response and whether the letter was actually present or absent. -Which cell represents a correct rejection?

Kyle performs a detection task in which he is asked to determine whether or not the letter T appears on a checkered screen. The table below shows the possible outcomes based on his response and whether the letter was actually present or absent. -Which cells represent correct detections?

Which method of determining absolute thresholds is very time-consuming and utilizes pre-tested stimuli?

Smaller Weber fractions indicate:

The results from a signal detection experiment are often plotted in:

In the __________________, the experimenter presents a stimulus that is clearly noticeable and then presents increasingly weaker stimuli until the participant cannot detect it.

The distributions below show the results from a signal detection task that Eric and Diane participated in. -Which participant will make more false alarms?
