Q

Field study

A

And investigative technique in which behaviors and events are observed and recorded in their natural environmentproblems are that field studies do not provide information about causality and also there maybe so many factors affecting real life situations that is impossible to control and even distinguish all variables.

Q

Interviews

A

Get to know a client learn his or her life history and current situation and personality

60
Q

Highly structured interviews

A

Formal standardize interviews standard serious questions or standardize rating scales increases consistency and less subject to buyers

61
Q

Mental status examination

A

Uses questions observations and tasks to briefly evaluate her clients cognitive psychological and behavioral functioning

62
Q

Projective personality test

A

Testing involving responses to ambiguous stimuli such as inkblots pictures are in complete sentences. Tap into unconscious needs and motivations. Rorschach test, tat test.these do not need reliability and validity standards subject to error and variation in interpretation

63
Q

Rorschach test

A

Implant test taps into unconscious needs and motivations.personalities analyzed by attention to what you see in the blots. Unreliable and highly subject to clinician bias

Internal validity scales

A

Questions Bilton to know if you’re faking that answers

69

Personality test

71

I Q test

A

Stanford Benet test intelligence quotient is mental age divided by chronological age times 100

72
Q

W a I S

A

The Weschler adult intelligence scale for adults 16 and older measures for areas verbal comprehension perceptual organization working memory and processing speed. Follows bell curve.

73
Q

Correlation between intelligence tests and neuropsychological tests

A

There is high correlation if one section and Waze is way off tells you something neurological going on brain damage intelligence tests are low and then achievements should be low. Intelligence hi but achievement low is a learning disorder.

74
Q

Criticisms of intelligence tests

A

They predict future behaviors or achievement. Sternberg describes intelligence as involving analytical proficiency (abiity to analyze and evaluate ideas, solve problems,and make decisions), creativity ,and practical skills ,characteristics not assessed by most IQ test

75

Bender-Gestalt Visual-Motor Test

A

Nine figures are shown to the participant and they try to copy them if they are stored. If including rotation of figures on usual continuation of the pattern and inability to copy angles, brain damage.

78
Q

Halstead-Reitan

A

11 test with tasks that assess sensorimoter, cognitive, perceptual functioning, abstract concept formation, memory and attention. 6hrs and expensive.

79
Q

Neurological tests

A

Can noninvasively visualize brain structures and brain functioning. CT’s MRIs structural imaging and functional imaging such as EEG MEG, pet scan, functional MRI,SPECT test

80
Q

Structural imaging tests

A

Computerized axial tomography CT scan are three dimensional cross-sectional brain structure images generated by combining multiple x-rays good for diagnosis but high radiation. MRI uses read your Waze with in a magnetic field to create images by scanning one layer time to produce a clear cross-sectional picture of the brain do not involve radiation and cancer more detailed and more expensive

81
Q

Functional imaging methods

A

Study psychological and bio chemical process in the brain EEG measures electrical activity and brand of seizures, MEG uses electrons in a helmet to measure electrical activity in the magnetic field close to the brain more accurate locating dysfunction.

82
Q

More functional methods

A

Functional MRI uses magnetic field and radio waves to measure changes in blood flow and oxygen ,clots and location and patterns of brain activation. DTI variation of an M are I give us info on axons and nerve fibers and connections white matter injury. PET nuclear imaging technique computer monitoring of a radioactive tracer can measure neural chemical changes activity of meurotranitters, and Spect, cheaper less detailed nuclear.

83
Q

Diagnostic and statistical manual of mental disorders

A

List all official mental disorders in the characteristics or something is needed to confirm diagnosis including diagnostic area of physical behavioral and emotional characteristics associated with this order and different degrees of impairment. Based on the classification system Mr. Kraepelin developed around 1850

84
Q

Categorical model

A

Provides a category or label for each disorder DSM. But DS am also use this subtypes specifiers and disorder specific severity measures and cross cutting assessments

85
Q

Dimensional classification systems

A

Disorders reside on a continuum with normality at one and in the severe form of a disorder at the opposite end. Not DSM

86
Q

Subtypes

A

Distinctly different subgroups within a diagnostic category only one subtype can apply to each diagnostic category

87
Q

Specifiers

A

Clinicians can use them to indicate whether a person has certain characteristics associated with the diagnostic category people can have multiple specifiers. Include remission early or late onset of a disorder that affects .prognosis

88
Q

Cross cutting measures

Allows client and clinician to great symptom measures that are beyond those associated with the diagnose disorder symptoms that are not specific to one disorder
