Psych 100 Class Notes #1 09/03/2015 ▯ What is Psychology? Its what people do in their lives What they are thinking and feeling Human (animal) behavior (doing) Mental processes (thinking/feeling) o “psyche” = life o “logos” = explanation ▯ Learning Applications: Mnemonic devices o Please excuse my dear aunt sally Images ▯ How do we know things? Repeated exposure Authority Personal experience Hypothesis testing; evidence ▯ Hindsight bias “That’s OBVIOUS” o two equally plausible explanations given o only one has supporting evidence ▯ History of Psychology Who was the first psychologist? Ancient thinkers: o E.g., Plato, Aristotle o Descartes, Locke, Hume o Religious Leaders (Buddha) Experimentalists (1800s, 1900s) o Pavlov, Watson, Skinner ▯ Plato Plato: the mind is imprinted with all of the knowledge it needs ▯ Ancient Thought: Aristotle: Para Psyche “mind”= “soul” Galen: four “humors” o Sanguine: the blood, (air and liver), courage, hope and love o Choleric: yellow bile, (fire and gall bladder), bad temper and anger o Melancholic: black *** ▯ Related fields: Philosophy (ideas and theories) Biology (neuroscience, evolution) Sociology (norms, trends) Anthropology (human roots and animal traits) Linguistics (communication) Economics (consumer behavior) Political science (voting, decisions) ▯ Schools of thought Structuralism- introspection, experience o The idea that we can learn about the mind through direct personal experience o Earlier studies asked people to describe what was going on in their minds Functionalism- aspects of particular parts of the mind o Different parts of the brain/mind serving different functions or roles Psychodynamic- unconscious processes o Things that are happening below our conscious awareness but have an impact on our wellbeing or behavior Behaviorism- attention to only observable behavior, and learning processes o Reinforcement and conditioning, only with what we can see Cognitive/neuro- mind as a computer; biological bases of behavior o The mind is keeping some relative information and getting rid of other information, using the leftover info and some output Socio-cultural- power of situations and environmental forces o Things in our environment that impact our behavior o Language, time of day, weather, what are the colors of the walls, etc. ▯ Big questions Nature vs. Nurture o Innateness and experience o How much we can explain about behavior based on what people are born with vs. what is learned through experience Free will vs. determinism o Control of outcomes Conscious vs. implicit o Processes- awareness ▯ Level of analysis Lower: biological o E.g., genetic predictors of alcoholism Middle: interpersonal o E.g., peer pressure to drink Upper: cultural o E.g., prevalence, legal status, advertising ▯ Evolutionary psychology Natural, sexual, and artificial selection Reproductive fitness, adaption o Thoughts and behaviors can be acquired How do we study this? o Fossil record o Cross-cultural similarities Hunter-gatherer tribes o Animal behavior Something about our minds that were working that what is adaptive o If it was adaptive then it got passed on What sets humans apart from other animals? o Sophisticated communication/language o Extreme empathy o Extended immaturity (development) Learning Bias o Mind has a template, not blank state Guides learning and relationships Contrast to “fixed action patterns” Flexibility to different social environments ▯ Socio-cultural Theory Groups develop norms (why humans are strange, quirkiness) o Not innate or adaptive o Not conditioned (often automatic) o Not rational (ex: academic regalia) o Often easily changeable What is ‘abnormal’? o Whatever is different/non-normative o Whatever is destructive o Whatever is painful o Whatever the group doesn’t tolerate ▯ Social Cognitive Theory Humans are going to develop schemas Schemas determine activity o Beliefs, knowledge (facts) o Attitudes (emotional reactions) o Memories (experience) o Mindset (expectations, motivations) When a schema is formed, it influences what people do o EX: you had a bad experience with roller coasters when you were young now whenever you see roller coasters it triggers that feeling and you are terrified o They guide behaviors through expectations, memories, mindsets Cognitive Psychology o Information processing o Mind=a computer Senses generate input, behavior is output Information is filtered, organized Inherent bias Much is implicit ▯ ▯ Behavioral Psychology- Week 5 10/01/2015 ▯ Review sessions Monday 6-8 Tydings 0117 Tuesday 4-6 Tydings 2111 Wednesday 6-8 Location TBD ▯ ▯ What is learning? Relatively permanent change in knowledge or behavior, resulting from experience o Only some of learning is academic o Learning is adaptive, helps navigation Behaviorists: learning=conditioning o Ability to connect stimuli (in environment) with responses (behaviors and actions) o This is how the mind is shaped to form new associations with things in the environment First thing you learn when you are born is interpersonal relationships o What and where their primary caregiver is Explicit o School based learning o Learn something and work for it Implicit o Learn something automatically by having stimuli repeatedly presented to you o Your mind absorbs it without having to put in any effort ▯ ▯ Conditioning: Before conditioning o Food (UCS) response salivation (UCR) Before conditioning o Whistle (NS) response No salivation (No CR) Q: a drug detecting dog has learned to sit and bark when it smells cocaine. The smell of cocaine is now the: o Conditioned stimulus Q: a drug detecting dog has learned to sit and bark when it smells cocaine. The act of barking at the smell of cocaine is o Conditioned response ▯ Classical Conditioning Have you experienced the Garcia Effect? o Effect is only for taste, not other senses o Taste aversion o Someone has a fear of a food because of a bad experience that happened in the past EX: Vodka Evolutionary perspective o “Acquired” tastes things that don’t have such a great sensation at first but we come to like them over time EX: Brussels sprouts, alcohol Alcohol is a social drink It is paired with something positive so we come to like it more over time ▯ Extinction Extinction is never 100% o Learning is faster the second time o You can learn something, then unlearn it, and learn it again o Even after a behavior is extinct, you may see it in the future because something reminds you of it – doesn’t last long ▯ Advertising Associative learning products/services o Take a product and pair it with something that provides a positive attitude EX: Bacardi and naked woman poster Can do the opposite—pair the competition with something negative ▯ Stimulus Generalization What did Albert generalize the learned association to? o He was conditioned to have a phobia to the rat o He generalized that fear to other things that were small and other things that were white Small animals, white objects Associated Santa with mouse because it has similar properties now fears Santa ▯ Stimulus Discrimination Differentiating between stimuli o E.g., similar looking foods o Again, advantageous o Being able to discriminate between stimuli and their features we can avoid things that are not good for us ▯ Second-Order Conditioning nd CS paired with 2 NS CR o EX: Christmas time and shopping Thanksgiving and shopping Black Friday and Christmas ▯ Phobias Learning bias Fear of particular stimulus o Evolution predisposed to make it easier to learn fear of predators (e.g., snakes, spiders), heights (trees), or storms (e.g., lightning) o They aren’t born with it o Small threshold for it all you need is just one negative experience and now you have this phobia May not be a direct personal experience Can be something that was told to you, etc. ▯ Systematic Desensitization Also useful for PTSD treatment ▯ The concepts of behaviorism and behavior psychology can be applied in many different ways. ▯ ▯ Operant Conditioning Thorndike: o Responses that create a pleasant outcome are likely to occur again, whereas responses that create an unpleasant outcome are less likely to occur again. Pair behavior with reward o Positive reinforcement ▯ ▯ Conditioning Description Outcome Example Type Positive Add pleasant Behavior is Giving students a Reinforcement stimulus strengthened prize after they get an A on a test Negative Remove Behavior is Taking painkillers reinforcement unpleasant strengthened that eliminate stimulus pain increases the likelihood that you will take painkillers again Positive Add unpleasant Behavior is Giving students punishment stimulus weakened extra homework after they misbehave in class Negative Remove pleasant Behavior is Taking away punishment stimulus weakened teens’ computer after they miss curfew ▯ ▯ Effectiveness Reinforcements are going to be more effective than punishments o Why? Positive relationship to reward provider Punishment based on coercion, creates adversarial relationship ▯ Shaping The differential reinforcement of successive approximations towards a target behavior o What if your grade was based on a mouse tournament outcome? The goal was to shape the students behavior Need to use as little reinforcement as necessary so that you can avoid satiation o This occurs when whatever you are trying to train/shape isn’t interested anymore (if the rat ate too much and doesn’t want anymore) Schedule Definition Example Fixed-ratio Behavior is reinforced after a Factory workers who are specific number of responses paid according to the number of products they produce Variable-ratio Behavior is reinforced after Payoffs from slot an average, but machines and other unpredictable, number of games of chance responses Fixed-interval Behavior is reinforced for the People who earn a first response after a specific monthly salary amount of time has passed Variable-Interval ▯ ▯ Effectiveness Variable >> fixed Ratio >> interval ▯ Superstitious Behaviors Skinner’s Experiment o Create superstitious beliefs in pigeons Think about how it may apply to your own life and others around you ▯ ▯ Q: For every 2 days my girlfriend watches football with me, I will watch maters of sex with her. What reinforcement schedule is this? HINT: 2 days interval o If he said 2 games it would have been ratio Answer: Fixed interval ▯ Q: My girlfriend wants me to speak in Hebrew with her, and every few times I speak in that language, she kisses me. Answer: every few times variable ratio If said every 2 days would have been fixed ratio ▯ ▯ Other types of learning Modeling (observation and mimicry) Insight: sudden understanding of a solution to a problem o Trial and error o Pause and reflect o Sudden inspiration AKA latent learning ▯ Bandura’s Bobo Doll Experiment Modeling increased the behavior ▯ Modeling ▯ Effectiveness Although effective reinforcement and punishments are extrinsic, not intrinsic o Intrinsic motivation value in the activity itself, not external conditions Education o Gold stars, good grades, and praise o But what will motivate students after they leave the classroom? More incentives? ▯ ▯ Psych Lecture Notes 09/24/2015 ▯ Q: Feeling that something is on the “tip of my tongue” illustrates… A retrieval error ▯ Psychology as a Science Experimentation and Data o Quantitative conclusions are less vulnerable to biases and intuition errors Replication is vital o Reproduce findings Being able to reproduce your own findings as well as other peoples findings If you have an idea, you should be able to support your idea with data, but anyone else who is skeptical should be able to do experiments and get the same results If you are the only one that can produce those results then that is a problem means you are doing something unique (your methods) not about the problem itself o Eliminate subjectivity/bias ▯ Psychological Science Goals: o Explain Variability What is a variable? Anything that can take on multiple values Something that varies Height, weight, religion, gender, hair color, education level, etc. o Study phenomena E.g., marriage/divorce rate Descriptive Of the marriages that exist, a % of them will get divorced Studying the thing itself o Study associations between variables E.g., rates of depression in men/women Analytic Whether being male or female associates with depression Associations between things ▯ Scientific Method Theory: o Explanation for a phenomena o Valuable because they help us understand things o Good theory will be testable and falsifiable Testable Design study’s that will test the theory Falsifiable Have the ability to show that it is invalid Some outcome that will show our theory is wrong o Parsimonious o Leads to multiple predictions Predictions in the real world (day to day life) and the laboratory o More broad – can be about a lot of different studies Hypothesis: o Hypothesis is more specific to the individual study you are conducting o Specific prediction for variables in a study ▯ Operationalization Going from the conceptual variable to the operational variable for your study Psychotherapy o Number of hours the patient has spend in psychotherapy Anxiety o Anxiety concerns as reported by the patient Multi-trait, multi-method approach o There are a lot of different ways in which we can operationalize something o Surveys, observations, physiological EX: Love Can be an emotional process, personality process, cognitive, etc. A lot of different ways in which the concept of love manifests in peoples lives Can ask someone on a scale from 1-10 how much do they love this person “Conceptual” replication o same construct, different method o when you try to assess the same theory and same hypothesis but using different methods EX: someone uses a survey and you decide to do a controlled experiment o We can combine all those studies into a meta-analysis Meta-analysis (k in hundreds) o Aggregate effect size o Increases our confidence in the theory o Gives us an overall affect if we combine across thousands of studies o This allows us to get an average affect size across all these measures and methods o This increases our confidence that the theory is correct ▯ Q: Which is an operational definition of self-esteem? Survey items on self-worth in Likert-type format o This choice combines exactly what were looking to measure (self-worth) using a suvey (which is a type of method) ▯ Validity Construct Validity o Measurement o Mainly has to do with the quality of your measures Just because someone gives you a survey on something, doesn’t mean it’s a good survey o The quality of the measure is the quality of the construct (idea or theory) Internal Validity o Refers to how well your controlling your experiments o Whether you are reducing the likelihood of an error in your experiment o Confounds, errors in experimentation External Validity o Refers to how well the results generalize to the rest of our world Do people engage in these type of behaviors in their day to day life? o About what we can say about our conclusions that go beyond o Generalizability (population and behavior) Statistical Conclusion Validity o How correct were our inferences based on the data we collected o Inferences based on data ▯ Research Design Correlation based on continuous data Correlational designs (continuous) o Variables are measured only E.g., graffiti and crime We cant conduct an experiment here because we cant get people to randomly do graffiti Instead we do a correlation study, the amount of crime and the amount of graffiti We can see whether an association exists but this doesn’t infer causation o Used when impossible/unethical to manipulate variables Does not necessarily indicate causation o XY o YX o XY and YX o ZY and ZX Un variable construct (theory) that is causing either X or Y Third variable problem ▯ Correlations High positive correlation o As one variable increases, so does the other o Both going the same direction Negative o As one variable increases, the other one decreases o Going opposite directions No correlation o Zero Correlations range from -1 to 0 to +1 o +/- just tell what way its moving Zero means NO relationship ▯ Experiments Allow us to conclude causality Random Assignment: o It is the only thing that separates experiments from non- experiments o Not attributable to pre-existing variables EX: being watched and generosity o Need this to have causality Random sampling: (IS NOT random assignment) o How you recruit the people for your experiment o Don’t need to have this in order to have causality ▯ Example Religionaltruism? o Religiosity correlates with generosity o ExperimentAnonymous dictator Manipulate IV (religious thoughts) using random assignment IV- whether people have religious thoughts in their head Measure DV (altruism) with money Operationalization: word-scramble prime Religious themed words (spirit, prophet) Neutral themed words (table, chair) Condition #1 higher money o What influences how much money people leave behind? We have people in our study who are exposed to words that contain religious themes In our control group we have neutral themed words (don’t have to do with religion) IV- religious thoughts and it is operationalized by giving people an operationalization task by giving people the words (either religious or neutral), DV - altruism The results of the study actually showed support for both hypothesis Results of the first study showed that those who were with religious themed words left more money behind Not necessarily the case that religion is causing people to leave more money behind (second study proved this) ▯ Controls Always need a comparison group in your study o Always needs at least two groups o No stimulus given o Neutral (similar) stimulus given EX: neutral words in study above^ o Placebo stimulus given Particularly in clinical psychology EX: trying to cure people or help people with their disease Give one group the experiment and one group nothing (makes them believe they will be helped) “Blindness” in studies o Participants unaware of hypothesis, condition If they know what it is then they could try to prove or disprove what is going on Could try to throw the results in one direction o Team unaware of p’s other info Especially true in studies including coding If the experimenter knows info about the p’s then it can change their opinions, etc. o RAs unaware of hypothesis, condition o If everyone is blind, it reduces the likelihood that some type of bias is going to throw off the results ▯ Experiments Within-subjects experiments: o All participants receive each treatment o Usually to measure change/improvement o Random assignment based on order o Condition 1,2,3 vs. 1,3,2 vs. 2,3,1 They all get the same stimuli but in different orders Eliminates carry-over, practice effects ▯ Research Design Quasi-Experiments: o Dealing with groups but the groups are naturally occurring o They exist but we don’t manipulate them EX: want to study race, age, etc. o Vs. correlational study Quasi- looking at categories/groups Correlational- looking at studies…?? Naturalistic Observations: o Don’t manipulate anything (just simply watch) o Coding Have to create some type of coding system in order to translate the behavior we see Whether or not they cry Ex: watching behavior of people boarding the plane after 9/11 o Archival research Experience Sampling: o EX: diaries – write down your thoughts and feelings everyday and that will give us our results Could put devices on people that could record their behavior Longitudinal studies: o Used to measure change in a developmental sense o Over long periods of times Case Studies: o With single individuals o Mostly in clinical psych Rarely see them anymore (only very interesting cases) ▯ Psychological Science Everything is probabilistic, not deterministic o Based on statistics, not laws o Nothing is ever proven! Nothing is ever certain Never use the word “prove” in this class Can say “I demonstrated support for this hypothesis” o Why? Can’t isolate variables As humans we are too complex If you are trying to demonstrate that a personality trait correlates with something in the future You can’t isolate that variable ▯ Q: A research team observes that male athletes curse more than female athletes. This is a… Quasi-experiment o Because the groups are naturally occurring ▯ Research (not tested much on)** Written (lab) reports o Intro Stating what is being tested (the hypothesis) o Method Operationalization is in here o Results Contains the numbers o Discussion Conclusions (what can we say about human behavior, etc.) Journals, books o Psychological Science, Journal of Personality o Communication o Outreach? ▯ Research Ethics Is this ethical? Who decides? Institutional Review Board (IRB) o Costs, benefits Learn about disorders; vs. unpleasant stimuli They measure if the benefits outweigh the costs o Deception, consent, debriefing (at end) o Care, freedom, privacy How we treat participants Want to protect their dignity Want to protect peoples personal info Want to protect them from harm o This is the committee that exists for every research group in the world… Oversees each research’s design Decides whether its worth it Facebook and OKCupid experiments o Facebook: They took a group of 700,000 fb users and randomly assigned them to a group whose newsfeeds had more positive words and thoughts Lead people to feel more positive There was an uproar because people didn’t give consent There was an outcry because of ethics o OKCupid: Dating website Some people saw a match with 90% and some with 30% People were more likely to choose someone they had a bigger % with Concern was the ethics of not informing people and getting their consent ▯ ▯ Biological Foundations 11/01/2015 ▯ A note on the brain: Holisitc Perspective o All of the brain does everything Certain regions “specialize,” but not 100% Involves intense amounts of communication Plasticity o Repair, extend functions, esp. in response to learning/damage o The brain has an incredible ability to heal its self by adapting over time o Some brain areas will accommodate the lack of function for others Filling in for other parts Brain processes objective information o But this is only a small fraction Most of the human brain’s activity is geared toward simulating the world o This is response for most of our suffering… The brain is influenced by social factors o Social environment brain development (maturity), regulation, output o It is not the primary source of a causal change of events We tend to think the brain is the source of things (emotions, behaviors) o Is the brain the true source? ▯ Go over textbook definitions of neurons/soma/dendrites/etc. ▯ Neurotransmitters: Over 100 billion transmitters in the brain A neuron can have over 1000 dendrites Over 100 different types of neurotransmitters have been identified ▯ Drugs: Binds to receptor cites on dendrites o Causing excitation or inhibition Agonist o Behaves like neurotransmitters o E.g., cocaine dopamine When you ingest cocaine it literally mimics dopamine Antagonist o Stops normal neurotransmitter effects o E.g., curare (poison) stops acetylcholine It stops processes normally happening in humans that allow muscular movement causes paralysis and death ▯ Neurotransmitter: Acetylcholine o Stimulates muscle contractions, memory, sleeping/dreaming o Lowers Alzheimer’s disease, nicotine is agonist Dopamine o Movement, motivation, emotion, reward/pleasure, love o Increases schizophrenia o Lowers Parkinson’s disease Endorphins o Response to vigorous exercise, orgasm, spicy foods o Pain relief, found in opium, morphine, and heroin GABA (gamma-aminobutyric acid) o Major inhibitory neurotransmitter o Lowers involuntary motor actions, tremors, seizures o Alcohol increases GABA, inhibits nervous system Glutamate o Common excitatory neurotransmitter (present in more than 90% of synapses) o High levels of Glutamate can cause overstimulation, migraines Serotonin o Mood, appetite, sleep, aggression o Lowers anxiety (SSRIs) prevent reuptake ▯ Neuropeptides: Opioids o Buffer stress, reduce pain, produce pleasure o Includes endorphins Runner’s high Oxytocin o Promotes nurturing (kids/couples) o Women will have higher levels o Increases aggression under threat Vasopressin o Pair bonding, social monogamy o Induce aggression toward romantic rivals Cortisol o Released during stress response, stimulates amygdala, inhibits hippocampus o Chronic stress can lead to lower levels, bad for coping ▯ Three Stages of Brain Evolution: Reptilian: o Brainstem, cerebellum, hypothalamus o Reactive and reflexive avoid hazards Most crucial for life, cant live without First things animals in the world did (avoid hazards) Mammalian: o Limbic system, cingulate, early cortex o Memory, emotion, social behavior approach rewards Pleasurable Approaching things that are good for you and learning about which things are bad and which are good Human: o Massive cerebral cortex o Abstract thought, language, cooperative planning, empathy higher order thinking (Calculus) Bad >> Good: “Bad is stronger than good” o Bad things weigh more on our minds than good things o “The quick and the dead” if people are going to survive, they need to learn how to avoid danger before they approach good thigns o Loss/risk aversion Loss aversion – it feels worse to lose 100$ than it is to gain 100$, think about how much psychologically changes in a person o Leanred helplessness & anxiety – easier to learn Those things are easier to learn relative to happy things (have good working relationships)- tragic that it is easier for us to learn to be helpless but it is true o Bad info about others carries more weight than good info ▯ Brain Regions: Brain stem: o Oldest part of the brain, most crucial for basic life function (heartbeat, breathing) o Medulla- most essential (others above can be removed) o Pons- walking, balance Limbic system: o Amygdala- “alarm bell”, fear, emotional memories o Hippocampus- long-term memory storage, memory encoding Hippo on Campus (will remember it for a long time) Cerebral Cortex: o Consciousness, critical thinking, moral, judgment o Language, complex skills, create tools, and construct large social groups This is what allows us to go to the moon, have the UMD ▯ Synestheia: ▯ Brain Damage: Language is lateralized in the left hemisphere Broca’s Aphasia – language production o Ability to form words Wernicke’s Aphasia – meaning o Have words that have coherent meanings Constructional Apraxia o Right parietal lobe damage = unilateral neglect Prosopagnosia – faces o Facial recognition ▯ “Split Brain” Syndrome: ▯ ▯ Relation and Perception 11/05/2015 ▯ Midterm November 12 : th Consciousness Sex & relationships Biological foundations Relation and perception ▯ Definitions: Sensation: awareness resulting from the stimulator of a sense organ o The info as it hits our eyes, ears, skin Perception: the organization and interpretation of sensations o What the brain does with that information Psychophysics/biophysics: o Effects of physical stimulion sensory perceptions and mental states Transduction: conversion of stimuli (detected by receptor cells) to electrical impulses, then transported to the brain (via neurons) Absolute threshold o Bare minimum stimulus for detection o Signal detection analysis- distinguish true signals (hit) from noise (miss, false alarm) o Just noticeable difference – change in a stimulus that can just barely be detected by the organism EX: You see the light, then the light changes (gets brighter), can you detect that change? ▯ Absolute Thresholds: What can we detect? o Equivalent of candle flame 30 milesa way o 300,000 of different colors o sounds as low as 20 hertz (vibrations per second) and as high as 20,000 hertz o tsp of sugar dissolved What about below the threshold? o Recall: priming When idea is primed in the mind, it usually comes from some stimulus outside of the conscious mind o However… Effects are short-lived What can’t we do? o Dogs, bats, whales, rodents, all have much better hearing, smell, sight o Birds can see UV light and can sense the earth’s magnetic field o Cats navigate in darkness using their whiskers ▯ Evolutionary Perspective: Response bias o Favor false alarms over misses Would rather think something is there and get it wrong then miss it completely o Risk aversion Better to flee if there’s danger More moved by danger than loss Applications for foreign policy, medicine o The Cheney 1% doctrine o Over-testing and positive diagnosis ▯ Seeing Patterns?: Pareidolia- make shapes out of random objects (e.g., seeing animals in clouds) o Our minds try to make sense out of it o We want to see meaning in things that are meaningless in our day-to-day lives Autokinetic effect o Put yourself in a dark room (completely) and turn on a very small flashlight, if you look at the light you will perceive it to be moving (it is a false positive) Survival/adaptive value?
