Finals for PSY 150 Flashcards
What is psychology?
The science of behavior and mental process
Positive Correlation
positive correlation: two things either go up or down
Ex: The more time you run the more calories you burn. (Positive correlation)
Negative Correlation
One factor goes up and the other comes down.
Ex: If the temperature decreases heating bills increase. (negative correlation)
Correlation does NOT cause causation. (T or F)
True
Approaching the situation in three different ways, not only one.
Biopsychosocial approach
Biological (genes, brain, sensation) ,
Psychologically (thoughts, emotions, moods), and
Socially (environment, social influence, education, relationships)
this person believes we inherit ideas and intelligence (nature/inherit)
Plato
this person believes we develop our ideas and intelligence through the environment
Aristotle
Who we are is based on genetics/biological.
Nature
how the environment shapes who we are
Nurture
The ______ itself carries electrical messages from one neuron to the next in order for your body to perform
Neuron
Components of the neuron and their function
- Dendrites: receives the messages
- Axon: takes message from dendrites and sends it to the next cell body.
- Myelin Sheath?: Helps neurons send message effectively
- Synaptic Gap: area from one neuron to the other
composed of the brain and spinal cord. The brain process information and the spinal cord take in the message.
The central nervous system-
Composed of autonomic and somatic. Automatic is involuntary movements/actions. For example, breathing or heartbeat, you do not think about it. On the other hand, somatic is the voluntary movements that you have to do with thinking, such as picking out an outfit.
Peripheral Nervous System-
touch perception
Parietal Lobes
language decision
Occipital Lobe
Associated with working memory, speech production, and movement.
Frontal Lobes
Language, learning, memory, and hearing.
Temporal Lobes
the idea that only those who have the traits for survival will continue to produce more babies. and who was it proposed by?
Natural selection and it was proposed by Charles Darwin
The principle that information is often simultaneously processed on separate conscious and unconscious track
Dual Processing
brains ability to only focus on one thing
Selective attention
failing to notice change in your environment because you’re not paying attention.
Change blindness
a 24-hour cycle in the physiological process of living beings.
Circadian rhythm
Stage one: Alpha and theta waves (can easily be waken up)
Stage two: Theta waves (relaxed, kind of easy to wake up but not as easy.
Stage three: Extremely slow brain waves, delta waves.
REM sleep: active period of sleep marked by intense brain activity.
Brain activity during various stages of sleep-
the more exposure to a drug the less affect it will have on your body.
Tolerance
is a craving, need, or desire.
Addiction
Prenatal Development
- Zygote- first step of prenatal development
- Embryo- inner cells
- Fetus- when the baby begins to look like a human
- Sensorimotor stage- birth to two years- learning through our senses/environment
- Preoperational stage- 2-7 years. Representing thing withdraws and images using initiate rather than logical reasoning. Ex: pretend play (peek-a-boo)
- Concrete operational: 7-11 year thinking logically about concrete events; grasping concrete analogies and performing arithmetical operations.
- Formal Operational: abstract logical, potential for mature moral thinking.
Jean Piaget’s developmental theory and stages
parents controlling/harsh over child (dominant).
Authoritarian-
doesn’t enforce rules, lets child do whatever they want.
Permissive
most accepted form of parent, enforcing rules that children understand and accept.
Authoritative
mild distress when mother leaves, seeking contact when she returns.
Attachment theory: secure
not exploring, clinging to mother, loudly upset when mother leaves.
Attachment theory: Insecure (anxious style)
doesn’t care if mother leaves or stays
Attachment theory: Insecure (avoidant style)
eight stages, in which a healthy developing individual should pass through from infancy to late adulthood.
Erik Erikson’s Psychosocial Development Theory
A gender which an individual identifies as
Gender identity
how we express gender (ex: hair length, clothing, makeup)
Gender expression
societies expectations of behaviors associated with our gender (ex: certain work, housewife, provider of the family)
Gender roles
A gender in which an individual is attracted to.
Sexual orientation
organs/physical characteristics directly involved in reproduction. Ex: men’s testes, vagina, fallopian tubes, uterus, vagina canal, XY XX chromosomes.
Primary sex characteristics:
visible characteristics that distinguish is associated with each gender. Ex: breast (females), facial hair,
Secondary sex characteristics
the experience through your senses of the outside world. (seeing)
Sensation
how you decide to interpret those sensations. (meaning)
Perception
Lower sensitivity, lower reactivity. As you constantly experience something you become adaptive to it, used for survival. (Ex: faces, smells)
Sensory adaptation
- Cornea- helps focus the light
- Pupil-lets light in so you could see
- Iris-muscle that helps dilate the pupil
- Lens- helps project light into the retina
- Retina- consists of two receptors, the rods and the cones. The rods help us see black and white and help us see in the dark and peripheral view. The cones help us see sharp colorful details in bright light.
Structure of the eye
Ivan Povlov
father of classical conditioning
learning that two things are associated.
Classical Conditioning
Classical conditioning stages
US-an object that produces a natural response
UR- a natural response
CS- Have to do something to the object to create a response (was once a conditioned stimulus)
CR- a response to the conditioned stimulus
voluntary actions/consequences
Ex: in his experiment the rat would push the lever in order to receive food (its rewards)
Operant conditioning
B.F. Skinner
father of operant conditioning
Positive punishment: adding something negative to decrease behavior
(Ex: putting soap in a child’s mouth when they say bad words)
-Negative punishment: Removing something desirable to decrease behavior
(Ex: Taking away your child’s Xbox because their grades in school are going down).
-Positive reinforcement: adding something desirable to increase behavior
(Ex: Giving your child more TV time if that means they’re grades will continue to look fleeky)
-Negative reinforcement: removing something negative to increase behavior
(Ex: taking away someone’s chores so they could increase to do well in school).
Types of punishment and reinforcement
this study is an example of _______ ________. The child is conditioned to get scared of the white rat because the kid associated the rat with a weird/scary behavior.
Little Albert- classical conditioning
conducted the little Albert experiment (established the school of behaviorism)
John Watson
