Biological psychologist

Focus how the body and brain enable emotions, memories and sensory experiences, and how are genes and environment influence our individual differences

Biopsychosocial approach

How different aspects of human behavior are influenced by a combination of biological factors

Neuroplasticity

Brain’s ability to change build and reorganize after damage or experience easier for children than adult adults

Neurogenesis

The process of producing new neurons

EEG

Electrodes placed on the scalp measure electron activity in neurons

MEG

A head coil that records magnetic fields from the brain’s natural electrical currents

CT

X-rays of head generating images that may locate brain damage

PET

Tracks where radioactive form of glucose goes while the brain of the person given at performs a given task

MRI

People sit or lie down in chamber, uses magnetic fields and radio waves to provide a map of brain structure

Hindbrain

Survival functions, brain stem

Midbrain

Movement, sensation, communication

Forebrain

Largest and most complex, memory, emotion, personality

Brain stem

Oldest part of brain found at the base of the school above spinal cord

Reticular formation

Nerve network travels through brainstem controlling arousal

Medulla

Base of the brain, stem controls, breathing, and heartbeat

Consciousness

Are subjective awareness of ourselves and our environment

Cognitive neuroscience

The study of the brain activity linked with cognition, including language, perception, memory, and thinking

Dual processing

At any moment, we are aware of little more than what is in our conscious awareness, but beneath the surface, unconscious information processing takes place simultaneously

Parallel processing

Our ability to take in information about the look and movement

Sequential processing

Alternative parallel, we process one aspect of a problem at a time

Blind site

Condition in which a person can respond to a visual stimulus without consciously experiencing it. This is used to help explain how those without sight can sense objects in their environment.

Circadian rhythm

are biological clock that regulates our mood, temperature, and arousal through a 24 hour cycle

Stages of sleep:

NREM-1: light sleep, easily awoken

NREM-2: fully asleep

NREM – 3: deep sleep

REM: body relax as if paralyzed, but brain active as if it was awake

Sleep disorders:

Insomnia: problems, falling asleep

Narcolepsy; sleep disorder, characterized by uncontrollable sleep attacks

Sleep apnea; sleep disorder, temporary of breathing during sleep, repeated awakenings

Rem sleep, behavior disorder; not immobilized during REM sleep, physically acting out their dream

Night terrors; being terrified sleeping

Somnambulism; sleepwalking

Manifest content

Actual content of the dream

Latent content

hidden or symbolic meaning of the dream

Freuds wish – fulfillment

dreams, provide a psychic safety value – expressing otherwise unacceptable feelings; contain manifest content, and a deeper layer of a content

Info processing

Dreams, health, sore out days, events function; regular brain, stimulation, activation, synthesis; REM, sleep, triggers, impulsive, evoking, random, visual, memories

sleep paralysis

feeling of being conscious, but unable to move occurring when a person passes between stages of wakefulness and sleep
