Psych 202
Chapter 10:
Phonemes:
Speech sounds
Morphemes
The smallest component of speech that carries meaning
Basic definition of grammar
Combining morphemes into phrases and sentences using rules
difference between production and comprehension
Production:
Ability to use language
Comprehension:
Ability to understand language
Important milestones of language development
Comprehension develops before production
Babbling: 4-6 months
First words: 10-12 months
Vocabulary of 30-50 words: 18 months
Use of basic grammar: 18-24 months
Babbling
Experimentation with sounds of language
Production of phonemes
No grammar rules
Repetition
Do animals babble?
Yes, evidence of animals babbling (birds, monkeys, bats)
Sensitive period for language and importance
7 months in utero - 6 years
Critical exposure to language (easier to learn language)
How we know sensitive period starts before birth:
Hearing by 30 weeks of gestational age
Without being exposed to language during sensitive period
Feral children
Importance of social interaction:
Social interaction helps infants computational learning
Three different theories of language development:
Behaviorist
Language learning through operant conditioning
Nativist:
Learning language is an innate capacity
Interactionist:
Interaction of innate ability and social interaction
Adult language learning
Attentional interference
Leads to decrease in performance and more mistakes
Inhibition
Actively suppressing irrelevant information
Reversed dominance effect
Better in non-dominant language when using mixed languages due to inhibiting their dominant language (common in bilinguals)
Aphasia
Wernickes
Affects comprehension
Speech is fine, but is mostly nonsense
Brocas
Affects speech
Can still understand what is being said
Anomic
Problem with word finding
Stuttering
Symptoms:
Repetition
Prolongation of sounds
Blocks
Potential causes
Genetics
Feeling embarrassed or anxious about speaking out in front of peers
Dyslexia
Learning disorder
Difficulty with reading
Koeser Et Al (2015)
Independent variable
Language type
Dependent variable
Fill-in-the-blank task
Used either gender fair or masculine terms
Results
Gender differences
Differences after Ps made aware of gender terms
Visual languages like ASL are processed similarly to verbal languages
Whorf’s linguistic relativity hypothesis
A person with a richer vocabulary will think differently about a topic than someone who doesn’t know much about it (ex: a skier with snow vs someone raised in a tropical climate)
Predicts that using gender-free words decreases discrimination and gender stereotyping
Statistical learning
Infants pay attention to the frequencies of each type of sound that they hear
Overlap to process multiple languages
Uses same set of brain areas and networks
Chapter 11:
Schema:
Structured cluster of concepts on how the world works
Assimilation vs accommodation:
Assimilation:
Incorporation of new learning into an existing schema without the need to revise schema
Accommodation:
Incorporation of new learning into an existing schema that requires the revision of the schema
Piaget’s four main stages of cognitive development:
Sensorimotor:
Birth- 2 years
Interaction with environment
Object permanence
Preoperational:
2-6 years
Egocentrism
No conservation
Concrete operational:
6-12 years
Internal mental operations, but concrete (not abstract)
Hands-on learning best
Conservation (quantity remains the same even when appearance changes)
Formal operational:
12+ years
Abstract concepts
Problem solving that goes beyond trial and error
“What if” questions
Criticism of Piaget’s theory
Reduced focus on individual difference
Abrupt stages vs. gradual and continuous
Mechanisms for moving to a new stage?
Theory of Mind (TOM)
Extends Piaget’s concept of egocentrism
Emerges at 3-4 years
False belief (Sally Anne test)
Tests cognitive ability to attribute false beliefs to others
Temperament
Individual differences in patterns of moods, activity, and emotional responsiveness
Kagan’s test of reactivity
Predictive of temperament later in life, especially shyness
Attachment
Connect between infant and parent
Four different attachment patterns:
Secure
Avoidant
Anxious-ambivalent
Disorganized
Harlow’s test of attachment on monkeys
Would choose the cloth monkey over wire monkey with food
Reactive Attachment Disorder
Affects child’s ability to form attachments with parents
Caused by neglect between critical period for attachment (birth-5 years)
Two dimensions of parenting styles
Behavioral regulation
Parental support
Four parenting styles
Authoritative
Authoritarian
Indulgent
Uninvolved
Marshmallow Test:
Test of impulse control
Delay of gratification
Social factors that influence gender-role development
Toy play and gender stereotyping
Kohlberg's stages of moral development
Preconventional
Thoughts of punishment and self-interest
Conventional:
Conformity and following the rules
Postconventional
Goes from mutual benefit to things that transcend mutual benefit
Criticisms of Kohlberg’s Theory
Emphasizes justice to the exclusion of other values
Original study only used males
Some argue that some people never reach postconventional stage
Brain development in adolescents:
Growth of white matter, myelination
Amygdala fully developed
Frontal cortex continues to develop into early 20s
Adolescents are more likely to engage in risky behaviors because they believe that they’re immune to the consequences
Erikson’s 8 stages of psychosocial development:
Trust vs. mistrust (infant-18 months)
Autonomy vs. shame and doubt (18 months-3 years)
Initiative vs. guilt (3 years-5 years)
Industry vs. inferiority (5-13 years)
Identity vs. role confusion (13-21 years)
intimacy vs. isolation (21-39 years)
Generativity vs. stagnation (40-65 years)
Ego integrity vs. despair (65 and older)
Cognitive changes in late adulthood:
Mild changes in speed of learning and problem solving
More changes in fluid intelligence than crystallized intelligence
Primary milestones of prenatal development:
Zygote
Embryo
Fetus
Genetic and environmental risks due to prenatal development
Preemies are more at risk to develop problems later in life
Primary reflexes of newborns:
Grasping (also called Palmar)
Rooting
Sucking
Stepping (put baby’s foot on something will initiate stepping)
Babinski (stroking foot causes toes to spread out)
Blinking
Moro (if baby’s head falls backwards, they spread out arms in a hug)
Nervous system development
Have a ton of synapses that work under the “use it or lose it” where we eventually only keep the ones that we need
Vygotsky stressing the effect of culture and cultural differences in the development of a child (compared to Piaget)
Chapter 13:
Attribution
A judgement about the cause of a person’s behavior
Situational:
Behavior due to external factors
Dispositional
Behavior due to internal factors
Errors and biases situated with attribution
Correspondence bias
fundamental attribution error
Actor-observer bias
self-serving bias
Group-serving bias
Just-world belief
Attitudes
Favorable or unfavorable evaluations that predispose behavior towards a person, object, or situation
Attitude adoption as social inclusion
Learning: operant and classical, observational
Genetics
Cognitive dissonance
Uncomfortable cognitive state due to perception of contradictory information
Actions do not match beliefs
Dissonance reduction to maintain attitude consistency
Elaboration Likelihood Model (ELM)
Explanation for response to persuasive messages
Central route
Consider arguments carefully and thoughtfully
Quality of argument
Peripheral route
Evaluation shortcuts
Requires less attention
Fear appeal
Persuasive messages that use fear to encourage a specific action
Fear appeals can be effective depending on the message
Nyhan et al (2014)
Independent variable
Type of informational intervention
Dependent variable
Rating of how likely parent would vaccinate a future child for MMR
Belief perseverance
The tendency to cling to one’s initial belief even after receiving new info that contradicts or disconfirms the basic of that belief
Backfire effect
Given evidence against their beliefs, people can reject the evidence and believe even more strongly
Difference between prejudice and stereotypes
Prejudice
Attitude or prejudgement about others. Usually negative
Stereotype
Simplified sets of traits associated with group membership
Confirmation bias affecting stereotyping process
We search for information that confirms our preexisting beliefs and hypotheses
In-group favoritism
We tend to favor people in our own group
We tend to view people in an out-group more negatively
Robbers cave experiment (setting up a camp in two groups)
Implicit Association Test (IAT)
Tests unconscious attitudes
Avoids social desirability effects
Stereotype threat
Feeling of being at risk of conforming to stereotypes about your social group
Priming of stereotype information
Social norms
Rules for behavior in social settings
Difference between conformity, compliance, and obedience
Conformity
Matching behavior and appearance to perceived social norms
Compliance
Agreement to requests from others with no perceived authority
Obedience
Compliance to requests from authority figures
Asch study and patterns of conformity
Saying which line it is out of 3, people feel more pressured to conform to the group answer even if they know it's wrong since everyone else is saying it, so they try to justify to themselves that they’re wrong instead and answer what everyone else is saying
Beneficial functions of conformity
Useful in new or ambiguous situations
Reduces risk of social rejection
Compliance techniques
Foot-in-the-door
Start out with a small request and gradually build up to bigger requests
Door-in-the-face
Start out with a big request you know will get rejected, and then ask for a smaller request afterwards (they’ll feel pressured to say yes since they didn’t say yes to the initial request)
Milgram's study
Majority of people feel pressured to obey even as they’re showing emotional distress at the request
Deindividuation
Immersion of individual within group, leading to anonymity
Dehumanization
Depriving a person or group of positive human qualities
Social facilitation
The presence of others changes individual performance
Familiar or simple tasks
Higher performance
Unfamiliar or complex tasks
Decreased performance
Social loafing
Lower effort and motivation when working in a group vs. working alone
Group polarization
During discussion, members tend to take more extreme positions in direction they were already inclined to hold
Can lead to conformity
Group think
Group does not question its decisions critically; often leads to flawed decisions
First impressions are often times not accurate but they do persist
Cultural differences in terms of attribution
Differences between cultures that value individualism and collectivism
Individualism
self-serving bias
Collectivism
Group-serving bias
Things that can affect persuasion
Age and intelligence
A positive response to a speaker
Emotional appeals
Factors to reduce prejudice
Increased contact can reduce prejudice, but you need…
Equal standing
Common goals
Cooperation
Support from authority or customs
Factors that influence attraction and liking
Proximity
Exposure
Physical appearance
Similarity
Mere exposure effect
A situation in which repeated exposure increases liking
Attitude alignment
Being attracted to a person also increases similarity
Sternberg’s Triangular Model of Love
Has three points of intimacy, passion, and commitment
Creates many types of love
Factors for maintenance of relationships
May become easier over time with increased similarity
No response to bids can cause relationships to end
