When should a researcher most likely decide to use an ANCOVA
Only when there is an unanticipated extraneous variable
ANCOVA: co-varying out an extraneous variable, a variable that correlates with the outcome measure.
Phenomenolistic Causality
things happened together cause one another
considerable sensory integration
reduced plasticity
smoother accurate motor sequencing
occurs at what age?
7/8 years old
6/7

Anaclytic Depression
lack of maternal attention during 6-8 months of age: weepiness, withdrawal, insomnia
reaction formation
behave opposite of ones true impulses; being overly caring to mask aggression
Children of divorce
age difference
gender difference
recovery time
Younger children -
more anxious, unrealistic expectations of what caused it
adapt more quickly, fewer bad memories
3-6 yo feel responsible; young girls adjust better than boys
7-12 yo feel they could have prevented but also feel hurt and critical of parents; academic drop; teen girls more vulnerable and if mother remarries. Stepmother-daughter most difficult relationship.
Recovery 3-5 years; 2/3 adjust well, 1/3 lasting trauma
Fastest brain development is at what age, what %
birth -25%
2 years - 75%

Detouring
when parent expresses their dissatisfaction or concerns through one child.
e.g., insecurity about finances - "Your extra curricular is so expensive."
Minuchin Structural
Response polarization
When in group people tend to become love extreme in their views
Cross-tolerance
tolerance to one drug (e.g., benzodiazepines) also experience increased tolerance to another substance (e.g., alcohol).

The withdrawal of what substance can lead to death?
Alcohol and Sedatives, Anxiolytics (BZs); can also trigger autonomic hyperactivity, seizures
Who originated genogram?

Disjunctive task
Outcome is affected by the most effective member
Acetylcholine, Serotonin, Norepinephrine, GABA, DA
relating to what functions and disorders?
Acetylcholine: voluntary movement, learning, memory (hippocampus) - (low) Alzheimer
Serotonin: mood, appetite, sleep, sex, aggression, pain
Norepinephrine: mood regulation, stress response.
GABA: inhibiting nervous system activity and regulating anxiety
Dopamine: movement, emotions, reward and pleasure system, also certain types of movement- Parkinson's disease
MAOIs
- blocks MAO hyroxylase so that it cannot break down serotonin
- Effective in treating atypical depression (up appetite and sleep)
- avoid tyramine rich food: red wine, aged cheese, liver, dry sausage, picked or smoked fish or meat
According to Yalom, who are more likely to drop out from group therapy?
high somatization
high denial
Low motivation
severe pathology, low, SES, low IQ generally unlikable
overjustification hypothesis
extrinsic reward lowers intrinsic motivation (or something that was already intrinsically motivated)
If one is not differentiated, according to Bowen, this person will likely need more....
acceptance and approval from others
Cultural encapsulation
Therapist doesn't recognize cultural variation and only seeThings from his/her perspective
Generalized seizures
affects the whole brain
Always involve lost consciousness
Tonic/clonic (grand mal) - sudden loss of consciousness, follow by tonic (stiffening) and clonic activity (jerking)
absence (petit mal) - 1-30 brief change and conscious level with blinking, rolling eyes, blank stare.
Yalom- factors of effectiveness of group
cohesiveness - effectiveness
school of thoughts, leadership style, confrontation - do not contribute to effectiveness
Surface dyslexia
need to sound the word out otherwise cannot recognize word
Identity Diffusion
lack direction
not seriously considering options/values/goals
Extrapyramidal Symptoms (EPS)
Movement-related side effects of antipsychotics like dystonia and akathisia
Antipsychotics (mechanism and disorders treated)
Mechanism: block DA receptor thus reducing positive symptoms
neurocognitive disorder, delirium, Tourett's, Autism (to decrease oppositional behavior, emotional lability, irritability)
paraplegia
quadriplegia
complete paralysis of the legs
complete paralysis of 4 limbs
thinning
reduce the number of times reinforcer is offered (from continuous to intermittent)
L-Dopa
Levodopa
what is it
precursor to DA
partial seizure
Affect only part of the brain
simple - one of the lobes - Jacksonian, frontal lobe
Complex - impairment of consciousness, automatism (involuntary movement) lip, smacking, repeat nonsense phrase) - temporal lobe epilepsy
Name one sexual dimorphism
females have denser corpus collosum
Instrumental Conditioning
Operant Conditioning
How to determine the expected frequency in each cell in a Chi Square?
1. calculate the total number of cells - multiply the number of rows and columns (4 x 2 = 8).
2. divide the total number in the sample by the number of cells (120/8 = 15)
Lithium side effect
confusion, irregular heartbeat, nausea, diarrhea, abdominal pain, weight gain, tremors
Stable coalition
when one parent sides with one child against another parent
e.g., Mrs. Collins feels Mr. Collins is too strict with Liam. So she takes sides with Liam.

attributing our own success to internal factors (our effort, ability) and failure to external/situational factors
What does not declines with age
semantic and procedural mem;
verbal (not naming, speech comprehension and fluency)
ability to reason and use logic (but not novel problems solving)
Bowen emphasizes....
projection
differentiation of self
multigenerational transmission process

What is most critical for healthy adolescent emotional development?
self-acceptance
A physician would be likely to take the greatest care in prescribing a SSRI, tricyclic antidepressant, MAOI to someone with:
bipolar disorder - potentially trigger a manic episode
Symptoms of Alzheimer
early: memory problems, apathy, and depression
later: confusion, behavioral change, change in judgment
Phenylketonuria
PKU
phenylalanine from food --> phenylalanine hydroxylase --> tyrosine -->
L-Dopa —> DA
(tyrosine —> 5-HT)
But in PKU has defective phenylalanine hydroxylase, so can't convert to tyrosine
Phenylalanine level too high, tyrosine (DA, 5-HT) too low
need to be on a low phenylalanine and low protein diet.
