Neuropsychology allows for the relating of brain abnormality to particular _________?
|
Can relate the brain abnormality to the particular BEHAVIORS: it is not enough to show a lesion exists; we must demonstrate the consequences of the
lesion to the issue in dispute. |
|
Neuropsychology has appeal in legal contexts as experts can bring quantified ____________ __________ on brain/behavior relationships in areas typically based on mental status examinations and clinical interviews.
|
Neuropsychology has particular appeal in the legal context as the expert can bring quantified, normative data on brain/behaviour relationships to bear in areas typically based on mental status examinations and clinical interviews.

Historical perspective of neuropsychology
Originally used to ...............? Then came............? Which lead to a shift emphasizing ..................? More recently a further shift to predictions of ...................... ? |
1. Originally used to detect cerebral
lesions (usually in repatriation settings) 2. Development of sophisticated neuroimaging techniques 3. Leads to a shift on emphasis moves to outlining patient’s strengths and weaknesses 4.More recently a further shift to predictions of a patient’s functional skills, treatment options and rehabilitation potential |

|
1. Fitness to plead (rarely)
2. Impairment assessment 3. Predicting driving ability 4. Predicting vocational ability 5. Predicting financial management ability 6. Testamentary capacity 7. Medical decision making |

Russell (1990) has attributed the increased
use of neuropsychology in the courts to the fact that neuropsychology can easily diagnose brain damage _______ __________ ____ ________. |
Russell (1990) has attributed the increased
use of neuropsychology in the courts to the fact that neuropsychology can easily diagnose brain damage WHERE THERE IS NONE. |
|
No pathognomonic tests of brain damage,
false positives are due to the false belief that psychological tests are tests for “brain damage” when actually they are tests of cognitive abilities |
No pathognomonic tests of brain damage,
false positives are due to the false belief that psychological tests are tests for “brain damage” when actually they are tests of __________ ___________. |
|
It is not neuropsychological tests that diagnose brain damage, ___________ _______;hence the vulnerability
|
It is not tests that diagnose brain damage,
CLINICIANS DO; hence the vulnerability |
|
Traditional neuropsychological assessment
explains only a ________to ____________amount of variance in real world behaviours |
Traditional neuropsychological assessment
explains only a SMALL to MODERATE amount of variance in real world behaviours |
|
What is ecological validity?
|
It represents the degree to which an individual’s performance on testing can predict their real world functioning or the extent to which the environment
experienced by participants in a scientific investigation has the properties it is supposed to or is assumed to have by the investigator. |
|
Define: Impairment
|
Impairment (I) is the loss of psychological, or
anatomical structure or function |
|
Impairment (I) is the loss of psychological, or
anatomical structure or function = |
Impairment
|
|
Define: disability
|
Disability (D) is the restriction or inability to
perform an activity within the range considered normal for a human being arising as a result of the impairment |
|
The restriction or inability to
perform an activity within the range considered normal for a human being arising as a result of the impairment = |
Disability
|
|
Define: Handicap
|
Handicap (H) is the societal disadvantage to the
individual from the impairment or disability |
|
The societal disadvantage to the individual from the impairment or disability =
|
Handicap
|
|
Janice has aphasia. She is unable to use the telephone. She can't work as a receptionist preventing work as a receptionist.
|
Where is the impairment, disability, and handicap?
|
|
Neuropsychological assessment measures
deficit at the level of ____________. |
Neuropsychological assessment measures
deficit at the level of IMPAIRMENT. |
|
Most neuropsychological tests have not been empirically validated to predict the impact of impairment on ____________ _______ __________ _________ or _____________ ___________(i.e. handicaps)
|
Most neuropsychological tests have not been empirically validated to predict the impact of impairment on activities of daily living or instrumental activities (i.e. handicaps).
This has resulted in a considerable move within neuropsychology for increased ecological validity, in its procedures and practices. |
|
Crowe's series of studies looking at capacity to use automatic machines (phone services, atm, transport) demonstrated:
Are there specific cognitive tests that predict performance? |
Consistently high relationships between
neuropsychological measures and competency on automated machines. Many powerful predictors, not just specific tests or cognitive domains Neuropsychological measures in general showed high predictability of variance |
|
Money management study:
Neuropsychological assessment demonstrated a ________ ability to predict the overall score. |
Neuropsychological assessment demonstrated a
modest ability to predict the overall money management score (19% of the explained variance) |
|
Prospective and retrospective memory were
predictors, but ___________ __________were not. |
Prospective and retrospective memory were
predictors, but executive functions were not. |
|
Measures of what explain a large amount of (63%) variance in whether individuals with ABI made late payments of bills or rent, and classification success was high (89.3% of participants correctly classified)
|
Measures of memory explained.
|
|
What was strongly related to problematic impulse spending?
|
Measures of impulse control.
|
|
Performance on automated tasks offers the potential of being an accurate index of ___________ ___________.
|
Performance on automated tasks offers the
potential of being an accurate index of functional disability. |
|
Crowe's series of studies provide support for neuropsychological tests in ABI populations to determine capacity for what two things?
|
The results provide support for the predictive
validity of traditional neuropsychological measures in assisting in determining capacity to *manage personal finances and *automated machine usage in ABI populations |
