practice test 1 and quizzes for test 1

Question 1

biofeedback training for relaxation, we recommend _____.

Answer 1

spaced practice

Question 2

Which EMG bandpass provides the highest signal-to-noise ratio?

Answer 2

100-200 Hz bandpass provides the highest signal-to-noise ratio since this bandpass contains the most EMG power.

Question 3

_____ published early evidence that autonomic responses could be operantly conditioned, increasing the scientific credibility of biofeedback

Answer 3

Miller and Dicara

Question 4

If your voltage is 24 and resistance is 2, current is ___ amperes.

Answer 4

Current is 12 amperes since voltage (24) = current (12) times resistance (2).

Power refers to signal _____

Answer 6

signal amplitude

Who proposed the concept of the General Adaptation syndrome?

Answer 7

Selye

Question 8

Which is typically the strongest source of interference in sEMG recording?

Answer 8

60 Hz

Question 9

Who developed Autogenic Training in Germany?

Answer 9

Schultz

creased hand temperature during a single session when instructed without feedbac

Question 11

Filter slope is specified in

Answer 11

dB/octave

Question 12

Answer 12

light

Question 13

Answer 13

Basmajian

Question 14

A motor unit consists of an alpha motor neuron and 80-150 ______.

Answer 14

extrafusal muscle fibers

Question 15

theoretical model proposes that biofeedback produces nonspecific effects

Answer 15

placebo model

Question 16

first proposed the concept of homeostasis

Answer 16

Bernard

Question 17

During a stress interview, Roger’s heart rate increased and frontal SEMG decreased. This contradictory pattern illustrates the concept of

Answer 17

response fractionalism

Question 18

The ______ plays a central role in homeostasis by monitoring the body and initiating adjustments.

Answer 18

hypothalamus

Question 19

A rise in sympathetic activity could increase

Answer 19

sweating

Question 20

In an acute stress response, the adrenal medulla releases

Answer 20

epinephrine and norephinephrine

Question 21

Who popularized the concept of the General Adaptation Syndrome

Answer 21

Seyle

Question 22

Which hormone does the adrenal cortex release as part of a chronic stress response

Answer 22

Cortisol

Question 23

Which statements about stress is correct

Answer 23

Researchers have reported that increased illness and accidents follow increased stressful events. Scores on the Social Readjustment Rating Scale (SRRS) are only weakly (+ 0.30) associated with future illness. The SRRS assumes that major life changes equally affect individuals. Hassles better predict psychological health than major life changes

Question 24

Who proposed that stress is a nonspecific response?

Answer 24

Seyle

Answer 25

4 times
