Chapter 3 Day 3 //// Chapter 4 Day 1
Neuroimaging
Images of brain structure
CAT scan
o X-rays of brain
o Pictures in slices
MRI (magnetic resonance imaging)
o Strong magnetic field
o Improved resolution
Utility: locating tumors, injuries, structural or anatomical abnormalities
Images of brain functioning
o PET and SPECT
Injection of radioactive isotopes
React with brain oxygen, blood, and glucose
Reveal metabolic deficiencies
Advantages and limitations
o Yield detailed info
o Expense - bruh you need that insurance
o Lack adequate norms - best known psychological scale/inventory (MMPI)
o Limited clinical utility
Psychological Assessmet
Psychophysiological assessment
o Emotional or psychological events reflected by changes in the nervous system (sympath-
para)
EEG
o Brain wave activity
o Evoked potentials or event related potentials (ERP)
o Alpha waves (relaxation) and delta waves (relaxation during sleep and brain dysfunction
during wakefulness)
Ex. Nocturnal panic attacks
Possible exam questions *******************
All of the following statements are true about the MMPI except,
A. There is little room for interpretation - FALSE, tons of room for interpretation, determine the K,L,
clinical scales
B. The test is tedious and time consuming - TRUE
C. There is a version for adolescents - TRUE
D. Individual responses are examined to determine a diagnostic pattern - THIS IS TRUE, IT IS NOT THE
DSM, NOT DIAGNOSTIC

Chapter 3 Day 3 //// Chapter 4 Day 1
Examining Abnormal Behavior
Three important questions
1. What problems cause distress or impair function?
2. Why do people behave in unusual ways?
3. How can we help them develop more adaptive behaviors? INTERVENTION
Research by Experiment
Nature of experimental research
o Manipulate independent variable
o Observe affects on the dependent variable
o Attempt to determine causality
o Premium on internal validity
Studying individual cases
Case studies
o Extensive observation
o Detailed description
o Foundation for early developments
Freud
o Unique problems
o Contributions/challenges to theories
o Limitations - reactivity
o Heisenberg effect
Basic components of research
Hypothesis - educated guess - "Frank is upset with his job"
Research Design - plan to test hypothesis - "Ask Frank or go to his job site."
Dependent variable - some aspect of the phenomenon that is measured and is expected to be
changed ro influenced by the IV - "Behavior of Frank"
Independent variable - manipulated or though to influence the change in the dependent variable -
"Behavior of the experimenter
Internal validity - the extent to which the results of the study can be attributed to the independent
variable -
External validity - extent to which the results of the study can be generalized or applied outside
the immediate study - "Findings can be generalized to other situations"
Research by Correlation
The nature of correlation
o Statistical relationship
o No manipulated independent variable
Correlation and causation
o Positive correlation: "As people grow older, they tend to have more sleep problems"
o Negative correlation: "As people grow older, they tend to have fewer sleep problems"
o No correlation: "There is no relationship between age and sleep problems"
Nature/strength of correlation
o Correlation coefficient: -1.0 to 0 to +1.0
Statistical vs Clinical significance
Chance? .01, .05 - if you get a difference at .05, that's great. You want less than .05
