Test #1 things to know Flashcards
Reliability
degree to which a measure is consistent
Test-retest reliability
consistency across time
Inter-rater reliability
consistency across two or more raters
Validity
degree to which a technique measures what it is designed to measure. Did it measure what it was supposed to?
Concurrent/Discriminant Validity
comparing the results of one assessment measure with the results of others
Predictive Validity
how well the assessment predicts what will happen in the future
Face Validity
whether the test items look reasonable and valid at first glance
Construct Validity
degree to which the item measures something unobservable
Standardization
Application of certain standards to ensure consistency across different measures
Sensorium
general awareness of their surrounding
Biological Factors
Genetics, Neurobiology, Physiology
What are genes?
Blue print Long molecules of DNA Double Helix structure Located on chromosomes -46 chromosomes in 23 pairs -Pairs 1 – 22 = body and brain development -Pair 23 = gender
Single gene determinants
include disorders such as Huntington’s disease and Phenylketonuria
Epigenetics
how the environment changes gene expression
Eric Kandel
learning affects genetic structure of cells
Activation of dormant genes, continued development in the brain (plasticity vs hardwired), Diathesis-Stress Model.
Diathesis
Inherited tendency to express traits/behaviors (behavior/vulnerability)
Critical Period
phase in the life span during which an organism has heightened sensitivity to exogenous stimuli that are compulsory for the development of a particular skill. If the organism does not receive the appropriate stimulus during this CP, it may be difficult, ultimately less successful, or even impossible, to develop dome functions later in life.
Sensitive Period
for a particular ability is past, the development of the brain has progressed past the point at which information can be simply absorbed
Frontal Lobe
Thinking and reasoning abilities, memory
Primary motor cortex
Controls impulses, social awareness
Temporal Lobe
HEARING, auditory corex
Sight and sound recognition, long-term memory storage
Emotions and memory
Parietal Lobe
Touch recognition, body sensation, self-soothing/regulating/masturbating
Primary somatosensory cortex
Occipital Lobe
Integrates visual input
Optic nerves travel from your eyes to your thalamus and then back to you occipital lobe
Locus of control
internal and external- internal when you feel that you have control of your life, and external when other people have control of your life
Martin Seligman
Learned Helplessness- lack of behavior by person/organism when they encounter a situation that they feel they have no control. Develop symptoms of depressions. (Kids in Atlanta trying to go back to jail for “two hots and a cot” – also LEARNED OPTIMISM
