Final Exam Study Guide Flashcards
What is random sampling and what is random assignment? Why are they important?
RANDOM SAMPLING:
A technique in which each person is equally likely to be selected.
* Removes all hints of bias by (ideally) including all parties.
RANDOM ASSIGNMENT:
Randomly sorting the random sample into control and experimental groups.
* HELPS MITIGATE CONGOUNDING VARIABLES.
What is operationalization?
How you will measure a variable
(ex: What is hunger? -> “How hungry are you on a scale of 0-3)
What is the logic of the experimental method?
Experiments allow us to make causal conclusions (using independent and dependent variables!)
What are the 5 parts of the neuron?
1: Dendrites
2: Cell Body (soma)
3: Axon
4: Myelin Sheath
5: Terminal Branches of the Axon
What is the function of the Dendrites?
To receive information from other neurons and send it to the cell body
What is the function of the Cell Body (soma)?
Acts as energy center of the cell (contains nucleus)
What is the function of the Axon?
Carries electrical impulses to that the brain can send signals and communicate with the rest of the body
What is the function of the Myelin Sheath?
Allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down.
What is the function of the Terminal Branches of the Axon?
Change electrical impulses or action potentials within a neuron into chemical messages in the form of neurotransmitters.
What does action potential/neural impulse mean?
- ALL OR NOTHING flow of information that travels through axon caused by “Depolarization”
- Occurs when (excitatory signals - inhibitory signals <= certain threshold)
What do we mean when we say that the structure of the brain is contralateral?
Opposite-Sided: the left side of the brain is responsible for controlling a number of sensory and motor functions of the right side of the body, and vice versa.
What is selective attention?
When awareness is focused on a specific aspect of your conscious experience
- (focusing your attention on something automatically decreases attention to irrelevant things)
What are the two tracks of our dual-processing mind?
1: Conscious Track (the “sequential processing”)
- Deliberate concentration, action, or choice
2: Unconscious Track (the “parallel processing”)
- Automatic thoughts/feelings behind the scene
What is heritability?
The percentage of VARIATION of traits due to genes (NOT how genetic a certain trait is)
THE EXTENT TO WHICH VARIATION CAN BE ATTRIBUTED TO GENES
- May vary depending on which populations and environments are studied
When does heritability increase?
- Heritability INCREASES when:
1) The environment becomes more and more controlled (differences in behavioral traits become more tied to genes as the environment becomes more uniform)
2) Genetic variation increases (wider variety of phenotypes)
What are the differences between Collectivism and Individualism?
Collectivism:
- the self is part of a GROUP
- the self is FLUID across different situations
- personal DUTIES and group well-being are important
(Japan, Korea, Taiwan)
Individualism:
- the self is UNIQUE
- the self is STABLE across different situations
- personal GOALS and opportunities to express oneself are important
(USA, Canada, Germany)
How are sex and gender similar and different? Which definition does the proclamation on the family refer to?
Sex: the BIOLOGICALLY INFLUENCED characteristics by which people define boy, girl, man, and woman. (NATURE)
Gender: the physical, behavioral, and SOCIALLY INFLUENCED characteristics that are culturally associated with male and female roles and identity. (NURTURE)
- The Family Proclamation refers to SEX but uses the word gender.
What is Piaget’s Stage Theory of Development? How does this theory explain cognitive development?
4 Stages of (NATURal) Development
Jean Piaget’s ATTEMPT TO CATEGORIZE THE DEVELOPMENT OF COGNITION as children constantly try to make sense of the world.
* Cognitive development is shaped by the errors we make (we learn from failure)
What are the 4 stages of Piaget’s Theory of Cognitive Development?
- Sensorimotor Stage
- PREOPERATIONAL STAGE
- Concrete-Operational Stage
- Formal Operational Stage
What are the attachment styles we discussed in class? How can we discern between each style?
Secure Attachment
- Explore environment happily when caregiver is present
- Show distress when caregiver leaves
- Caregivers are responsive and attentive
(about 60% of children)
Insecure Attachment
- Cling to caregiver (do not explore) when she is present
- Caregivers only attend to children when they wanted to but ignored child otherwise
What is the difference between sensation and perception?
Sensation usually involves sensing the existence of a stimulus, whereas perceptual systems involve the determination of what a stimulus is.
What is classical conditioning?
PAIRING OF TWO STIMULI that eventually changes behavior
What are the Components of Classical Conditioning?
- Unconditioned Stimulus (US): automatically produces a response before conditioning
(ex: food) - Unconditioned Response (UR): automatic behavioral response to US
(ex: salivating in response to food) - Neutral Stimulus (NS)-> Conditional Stimulus (CS): neutral stimulus is paired with the US
(ex: ringing bell when food is presented) - Conditioned Response (CR): new behavior in response to neutral stimulus (which is now CS)
(ex: salivating in response to bell without food)
What is operant conditioning?
Formation of new active behaviors by using
LAW OF EFFECT: consequences of behavior will change future behavior–make behavior more or less likely to happen
(“If result is good, I do it again. If result is bad, I don’t”)
- Operant Conditioning leads to more complex behavior than just reflexes (U.R. and C.R.)
