Question

Michelle is participating in a research study. She has put on a set of Grado headphones and is listening to a stream of white noise. The experimenter has explained that every so often she will hear a quiet "click" in the noise and that she should press a button whenever she hears it. Michelle has a very conservative response bias and, as described in lecture, signal detection theory predicts that Michelle's response bias will cause her to have _______________ than more respondents who are more sensitive to the signal.

a. is likely to have more missesb. is likely to have more correct rejections.c. is likely to have fewer hits.d. is likely to have more false alarms.

Answer 1

Michelle's conservative response bias suggests she will have more correct rejections and fewer hits as she will press the button only when certain of hearing the click.

Step-by-step explanation:

Michelle is participating in a research study where she must identify a quiet "click" within a stream of white noise and press a button each time she hears it. Given that Michelle has a very conservative response bias, signal detection theory predicts that she will most likely have more correct rejections and fewer hits than respondents who are more sensitive to the signal. A conservative response bias indicates a tendency to respond only when sure about the presence of the signal, hence reducing the chance of false alarms at the expense of potentially missing some true signals (misses).

According to signal detection theory, Michelle's conservative response bias is likely to cause her to have more false alarms than more respondents who are more sensitive to the signal. In this case, a false alarm occurs when Michelle presses the button in response to background noise, thinking it is the signal she is supposed to detect. Due to her conservative response bias, she may be more cautious and more likely to respond even when there is no signal present.

Answer 2

Option (d).

Step-by-step explanation:

The individuals generally responses to the sudden noises and like to listen the noise that are pleasant to their ear. They develops a type of learning or memory against that noise.

Michelle has put on the headphones and listen white noise. She always click the button on listening the noise. She is more likely to develop the more false alarm that activates when she listen to that noise. She has developed a kind of response against the white noise.

Thus, the correct answer is option (d).
