psychology- Biopsychology

behavior

examines the biological basis cognition and _

biopsychology

focuses on brain (nervous system), the relationship between genes and behavior, relationship between hormones and behavior/cognition

diseases

biopsychology is valuable for understanding the biological basis for _ that impact behavior and cognition

biologically plausible

how the body and brain actually work in real life (how memory processes are implememted ny the brain)

adaptation

evolutionary psychology: framing behavior and cognition in the context of evolutionary _

fit

evolutionary psychology: physical and psychological traits were selected because they were _ for the environment and benefited survival

behavioral genetics

focus on individual differences in context of genes and environment interactions

behavior

frames _ and cognition as a result of gene/environment interactions

behavioral genetics

if the child is more like biological parents>genes matter more/if more like adoptive parents>environment matters more

evolutionary psychology

when tasked with recalling things people tend to recall items that would be most useful and prioritize info that is more important

behavioral genetics

child of mother with schizophrenia is more likely to develop this if raised in this family environment

chromosomes

long strings of genetic material made of DNA

genes

sequences of DNA make up _ that control number of observable characteristics (eye color)

alleles

specific version of a gene (given gene might code for hair color;different ones affect which hair color someone has)

genotype

genetic makeup of an individual

phenotype

your traits (how genes show up in body, behavior, eye color, height,etc)

homozygous

AA or aa same

heterozygous

Aa different

range of reaction

your genes set limit for a trait (like maximum potential) but environment decides where you actually end up in that range (with good nutrition u can be taller)

identical twins

what twins have single fertilized egg split

fraternal twins

two separate eggs fertilized by two dif sperm at the same time

glial cells

what is the cell type of nervous system that starts with a G

neurons

what is the cell type of nervous system that starts with N

neurons nutrients

the nervous system supports _ which transports _

membrane potential

difference in charge across the cell membrane

resting potential

pos net charge outside the cell, neg net charge inside cell

sodium

ions are more concentrated OUTSIDE the cell

potassium

ions are more concentrated INSIDE the cell

neurotransmitters

released by neurons

serotonin

example of neurotransmitters that starts with S

agonist

chemical that MIMICS natural neurotransmitter and activates receptor(helps the signal)

antagonist

chemical that BLOCKS and stops the signal

forebrain

what part of the brain includes thalamus and sensory relay, memory,emotion

midbrain

what part of brain helps sleep/wake cycle

hindbrain

what part of brain helps motor skills, breathing

automatic

the hindbrain is critical for many _ processes

action potential

the _ _ is the all or nothing process; an electrical signal that moves from the cell body down the axon

dendrites

_ collect chemical signals

memory

the limbic system is critically involved in emotion and _

automatic

the hindbrain is critically involved for many _ processes

supporting

glial cells can be thought of as _ neurons
