  2. exclude life events that might just be consequences of symptoms
  3. carefully date when a life stressor occurred
45
Q

What is a projective test?

A

form of self-observation involving collection of data in real time (e.g., diaries) regarding thoughts, moods, and stressors

59
Q

What is the Dysfunctional Attitude Scale (DAS)?

A

cognitive questionnaire that has been shown to differentiate people with and without depression

60
Q

What is the direct observation assessment method?

A

used by clinicians to identify problem behaviors and antecedents/consequences

61
Q

What is the self-monitoring assessment method?

A

people monitor and keep records of their own behavior

62
Q

What is brain imaging?

A

CT and MRI scans reveal structure of brain, PET reveals brain function and brain structure, fMRI assesses brain structure and brain function

63
Q

What is neuropsychological assessment?

A

behavioral tests assess abilities such as motor speed, memory, spatial ability; deficits on particular tests help point to an area of possible brain dysfunction

64
Q

What is psychophysiological assessment?

A

includes measures of electrical activity in the ANS, such as skin conductance, or the in the CNS, such as EEG

65
Q

What is a CT/CAT Scan?

A

a method of diagnosis in which X-rays are taken from different angles and then analyzed by computer to produce a representation of the part of the body in cross section

66
Q

What is magnetic resonance imaging (MRI)?

A

produces higher quality images and uses less radiation than a CT scan; uses a magnet to produce electromagnetic signal that is read by computer and translated into pictures of brain tissue

67
Q

What is a functional MRI (fMRI)?

A

allows researchers to measure both brain structure and brain function - blood flow in brain can be measured

68
Q

What is the BOLD signal?

A

stands for blood oxygen level dependent; is the signal detected by fMRI studies of the brain that measures blood flow and neural activity in any given region

69
Q

What is a PET scan?

A

stands for positron emission tomography, is more expensive and invasive (but less precise than MRI) - computer generated picture of living brain, created by analysis of emissions from radioactive isotopes injected into the bloodstream

70
Q

What is a SPECT scan?

A

stands for single photon emission computed tomography; is less expensive than PET scan - measures gamma rays produced by injection of radioisotope and generates images of activity in different regions of the brain

71
Q

What is connectivity?

A

aims to identify how different areas of the brain are connected with one another

72
Q

What are the 3 different types of connectivity?

A
  1. structural connectivity
  2. functional connectivity
  3. effective connectivity
73
Q

What is structural connectivity?

A

how different structures of the brain are connected via white matter

74
Q

What is functional connectivity?

A

the connectivity between brain regions based on correlations between their BOLD signal measured w/ fMRI

75
Q

What is effective connectivity?

A

combines both types of connectivity - reveals correlations between BOLD activations and the direction/timing of those activations by showing which cortex is being activating first, second, etc

76
Q

What are the 3 Halstead-Reitan battery tests?

A

while blindfolded, person tries to fit differently shaped blocks into spaces of a form board, first using the preferred hand, then the other, then both (sensitive to damage in right parietal lobe)

78
Q

What does the Tactile Performance Test for memory consist of?

A

after completing the timed test, person is asked to draw the form board from memory, showing blocks in their proper location (sensitive to damage in right parietal lobe)

79
Q

What does the Speech Sounds Perception Test consist of?

A

participants listen to a series of nonsense words, each comprising two consonants w/ long e sound in the middle, then select word they heard from a set of alternatives (measures left hemisphere function)

80
Q

What is an advantage of the Luria-Nebraska battery test?

A

one can control for educational level so that a less educated person won’t receive a lower score

81
Q

What is psychophysiology?

A

concerned with the bodily changes associated w/ psychological events

82
Q

A

a recording of the electrical activity of the heart, made with an electrocardiograph
