Psychology and Scientific Thinking Chapter 1 Psychology in NOT common sense. Consider these proverbs: o Out of sight out of mind o Better safe than sorry Now consider: o Absence makes the heart grow fonder o Nothing ventured, nothing gained Psychology is NOT just observations. Naïve Realism o Human beings have a tendency to believe that the world exists as they see it. Common sense and observation o Advantages and disadvantages Psychology- scientific study of the mind, brain and behavior. Goal of psychology - to understand why we think, feel and act the way we do. Levels of analysis o Social factors o Biological factors Levels: o Social level o Behavioral level o Mental level o Neurological level o Neurochemical level o Molecular level Depression o Social level – loss of friendship, lack of support o Behavioral level – not socializing anymore, not engaging in activities that used to be fun, withdrawal o Mental level – depressing thoughts o Neurological level – brain structures that function differently or are a different size, physical differences o Neurochemical level – higher or lower levels of neuro transmitters, why medications can be helpful o Molecular level – DNA, genetically predisposed to depression, not necessarily will be affected, but higher likeliness. Challenges Multiply determined – lots of factor that affect that way you think, feel and act. Influences are interdependent – the factors influence each other. Individual differences – humans are unique but also similar Reciprocal determinism – how other people influence each other Cultural influences – how culture affects how we think, act, feel Psychology as a Science Science o An approach to evidence o A set of attitudes and skills Theory and hypothesis A good theory will lead to testable hypotheses o Can be either supported or disproven Boundaries of science o Not testable? Not science; if you can’t test it, it’s not science. Bias We’re all biased Confirmation bias - the tendency to dismiss, or distort, or ignore evidence that refutes something that we already think or believe o we have a tendency to seek out information that agrees with what we already think and belief Belief perseverance – even in the face of contradictory evidence, you will not let go of a belief Psychological Pseudoscience: Imposters of Science Pseudoscience – a set of claims that seem scientific, but they’re NOT “Popular psychology” Signs of Pseudoscience Ad hoc immunizing hypothesis – people find loopholes to explain their way out of something that refutes their idea Exaggerated claims – people over-exaggerate on products Overreliance on anecdotes – anecdotes can’t be all the evidence No connectivity – absence of connection with existing knowledge No peer review – absence of the review process No self-correction – they never change their claims; no adjustment over time Psychobabble – something that sounds very impressive because of the wording but means nothing “proof” instead of “evidence” – when something says it has been “proven,” it’s not the language of science Dangers of Pseudoscience Harmful/ deadly Animal deaths Opportunity costs Inability to think critically Q. There are many factors that lead to the development of the disorder known as autism. One of these factors involves the expression of specific genes that impact how the brain forms new connections. This is an example of the ______ level included in the levels of analysis concept that describes how psychology is a discipline that spans multiple levels. A.Molecular Scientific Thinking Scientific skepticism o Evaluate claims with an open mind o Persuasive evidence before acceptance Critical thinking o Being open minded Principles of Scientific Thinking Extraordinary claims – they require extraordinary evidence Falsifiability – has to be testable; has to be something that you can disprove Occam’s razor – simplest answer is usually the best answer Replicability – can it be replicated Ruling out rival hypothesis – the need to consider other possible explanations Correlation is not causation – researchers cannot say that certain things caused certain outcomes; one thing doesn’t cause the other, they are only related Research Methods Chapter 2 The Necessity of Good Research Design “Facilitated Communication” o Developed to help severely autistic people communicate Research Process Steps: 1.Identify a problem 2.Review literature 3.Generate hypothesis 4.Design and conduct study 5.Analyze data 6.Interpret results 7.Communicate findings Types of research o Basic research – striving to further understand a concept o Applied research – you have a specific problem that you are trying to solve Naturalistic Observation Real-world settings o Covert observation Researcher is hidden o Participant observation Become member of group Sound easy? Pro: o High in external validity o External validity - The extent to which you can generalize your findings Con: o Low in internal validity o Internal validity – the extent to which you can attribute your findings to a specific variable Case Study Designs (studying rare things) 1 person/small # of people – follow and gather information o Tend to see biggest amount of data o Pro: Could be Existence proofs – proof that a phenomenon exists Rare/unusual phenomena Insights for later systematic testing o Con: Low external validity – can’t generalize Can’t infer causation Self-Report Measures & Surveys Participants – random selection o Must use random selection to get participants o Every person in your population has an equal chance of being in your sample Pro: o Easy to administer o Direct information (more than observational; you get their thoughts and feelings, and you don’t get that with observational) Con: o Lack of insight – the participants may not know why they did what they did or they struggle to verbalize it o Dishonesty Malingering – someone wants to look bad, generally to get out of something Evaluating Measures o Reliability – consistency Different ways to test reliability Test-retest reliability – consistent over different test over time Interrater reliability – how to test reliability in observational study; data is similar between different raters o Validity – the extent to which your measure assesses what it claims to measuring Content – looking at all aspects of what you measure Criterion – is your measure related o Valid – must be reliable o Reliable – can be completely invalid Correlation Designs Association / Relationship Correlation coefficient o Positive, Negative or zero correlation – tells direction of the relationship Positive – same direction Negative – opposite direction Zero – variables are not related -1 to +1 You must know both strength and direction to understand relationship -----------------------|--------------- Strong Weak Strong -1 0 1 How much of X is accounted for by Y? o Square the correlation .5=25% .8=64% Scatterplots No Correlation Curvilinear Relationship Illusory correlation- an illusion that there is a relationship/correlation when there is not Significant correlation coefficient o Still cannot infer causation Directionality problem – could be chicken or egg/ either way Third-variable problem – 2 things could be related to each other because of other variable that is connecting them Experimental Designs (only one that can determine causation) Independent and dependent variable (IV & DV)ir o You manipulate and control an independent variable o Dependent variable is like a measure or test Independent variable o Must be at least 2 levels for compare Experimental group and control group Random assignment – randomly assign the participants to be in the experimental group or the control group; every participant has an equal chance of ending up in either group; cancels out preexisting differences Control o External validity Placebo effect o “Blind” – participants don’t know what condition they are in Experimenter expectancy effect o Double-bind – both participants and researcher don’t know what condition they are in Demand characteristics – gets at any aspects of your study that your participants might pick up on so that they might try to figure out your hypothesis o Must minimize Observation Deception Confounds – anything that will mess up your data Conclusions o Cause and effect Q. A researcher interested in study environments randomly assigns 2 participants to 2 groups. Some participants study in loud room and the other participants study in a quiet room. Data collection occurs during the morning and later afternoon. IV? Study environments Levels of IV? Loud and quiet rooms DV? Measure of whatever it is they are studying; test on material Confound? Time of day Cause and effect? Yes Chapter 3 Biological Psychology The study of the connection between the brain and behavior Neurons Specialized nerve cells o Specialized For Communication o Soma/Cell body o Dendrites – roll is to receive signals and information from other neurons o Axon (tail) – signal will travel down and away from the body to the end to connect with the dendrites of the next neurons o Myelin sheath – helps the signals travel faster; allows you to think faster; allows to have complex thought Axon Terminal o Synapse - gap between axon terminal and dendrite o Neurotransmitters – flow across synapse to next neuron; carry information o Receptor site – neurotransmitters fit into receptor site Neuronal Communication Communication within neurons is electrical Communication between neurons is chemical Types of Neurotransmitters Some examples: o Acetylcholine Associated with muscle contraction o Dopamine Reward and motor function(ability to move) o Endorphins Pleasure/pain – “runner’s high” Drugs give your body the substance the neurons need. So the neurons do not produce the same amount of stuff; causes addiction How and when the Brain Changes Neural plasticity – your brain’s ability to adapt and change o Development Growth of dendrites and axons Synaptogenesis Pruning – when neurons die (good); trimming the fat or getting rid of the clutter; allows your brain to be better organized; use it or lose it Myelination o Experience Learning – causes physical changes in your brain Long-term potentiation – stronger connections between neurons; whenever you recall information you activate the same pathway and the more you activate the pathway, the stronger it gets Enriched environments – brains are physically different Neural plasticity and learning Neural Plasticity and injury Neurogenesis – the creation of new neurons; comes from theory and getting experience in speaking and moving as soon as possible after injury Stem cells – to replace neurons; possibility of creating neurons Corpus callosum – connect the right and left hemispheres of the brain Localization of function – a concept that specific areas of the brain have specific roles o However, the areas always work together Right and left hemispheres o Lateralization – some abilities are particularly associated with a specific hemisphere Especially the case with our language and verbal skills – they are more heavily housed in our left hemisphere o Split-brain surgery – cut corpus callosum; left and right brain perform independently Frontal Lobe o Houses the motor cortex – movement o Prefrontal cortex – where the highest level of cognitive functioning takes place; ability to think, plan, make decisions, and be logical Last to come(development) and first to go o Injury: Broca’s area Aphasia – inability or difficulty producing speech Personality Phineas Gage – survived accident of metal rod through his head, and his personality completely changed Not 100% sure he might’ve just been an asshole Parietal Lobe o Perception of orientation o Actions of others – being able to understand actions o Numbers – ability to use numerical skills o Somatosensory cortex – perception of temperature, touch and pain o Injury Acalculia – difficulty working with numbers Contralateral neglect – damage to right hemisphere of parietal lobe; neglect the left side of their body, but they don’t realize they are neglecting the left side Temporal Lobe o Ability to understand and comprehend language o Autobiographical memories – memories that are specifically about personal experiences o Auditory Cortex (hearing) o Injury: Wernicke’s area Aphasia – when a person can talk but in able to produce words that make sense Occipital Lobe o Visual cortex – increasing usage of other lobes (auditory cortex) o Injury: Alexia – difficulty reading Agraphia – difficulty writing Chapter 4 Sensation & Perception Sensation – detection of physical energy by your sensory organs Perception – your brain interpreting that sensory information Detection and interpretation Sensation Sense receptors o Transduces specific stimuli Transduction – turning the physical energy that’s received by your sense into neural activity Sensory adaptation – your original experience of the stimuli is the strongest; when you first experience that stimuli it is going to be stronger, and over time you get used to, or adapt that experience o Ex) Eyes adjust to light a few seconds after being in the dark Cross-modal processing/Sensory cross-modality/ Multimodal perception o Phosphenes – the presence of a sense without any stimuli When you see spots when your eyes are closed o McGurk effect – when your brain integrates what you see with what you hear o Rubber hand illusion when your brain integrates what you see with what you feel o Synesthesia – rare neurological condition where there is cross-modal processing between sensory systems and its happening to such an extent that people with synesthesia can do things like taste colors and sounds Attention How do we focus? Selective attention – your ability to focus on one specific sensory system while simultaneously ignoring other stimuli o Cocktail party effect – even though you are focused on one thing an ignoring everything else, your brain is still subconsciously taking in other information, and things can break you out of your selective attention. Ex) someone yells “fire” In-attentional blindness – ex) moonwalking bear Blinding Problem Mystery to us how these things all come together o Brain combines: Stimuli -> whole Apple o Look, feel, smell & taste – combination that tells us it’s an apple Q. A doctor is testing the hypothesis that people use hand gestures more in communication when emotionally aroused than when calm. When the results were reviewed, it was noted that the doctor sometimes missed seeing small gestures in the calm condition. This is an example of ____. a. Confirmation bias Perception Perceptual hypothesis – your brain is making an education guess about whatever is going on with the stimulation in your environment o Perceptual sets – when you are influenced by your expectations or experiences o Perceptual constancy – allows you to perceive stimuli consistently over a variety of situations o When perception deceives us Illusions Moon illusion The Unconscious Subliminal perception(legit; has research support) – you can still perceive stimuli at an unconscious level and can influence behavior by presenting stimuli at an unconscious level Subliminal persuasion(does NOT have research support) – does not exist; quick views of things try to make people do something they wouldn’t normally do o Ex- buy popcorn at the movies Extrasensory Perception (ESP) Perception in the absence of stimuli o Precognition – knowledge of something before it happens; predictions of the future o Telepathy - mindreading o Clairvoyance – claim to have knowledge about something that you cannot see o Absolutely NO scientific evidence to support these things Auditory Perception Localization of sound – your brain calculates where sounds are coming from Olfactory & Gustatory Perception Smell & taste – chemical senses and influence each other Pheromones – odorless chemicals that you smell; they do influence human sexual behavior; it’s NOT something you can take advantage of to make people behave a certain way o Ex- women’s menstrual cycles sync up o Social signals Somatosensory Perception Skin o Touch and pressure o Temperature o Pain Gate control model – a theory that says the perception of pain can be blocked with distractions Things seem like they hurt worse when you try to sleep Unusual cases of somatosensation o Pain insensitivity Disorder where people do not perceive pain or discomfort o Phantom limb illusion People who can feel a limb that is not there Chapter 5 Consciousness Our subjective experience of the world, our bodies and our mental perceptions o Its subjective because it is open to your interpretations Sleep Circadian rhythm o Cyclical changes – happen on a regular schedule; pattern o There are biological changes that occur on a roughly 24 hour schedule Suprachiasmatic Nucleus (SCN) – send signals to other parts of the body; they are sent in adherence with the circadian rhythm; signals are telling the body to do things on a schedule o Hypothalamus Controls levels of alertness The level of melatonin your body releases – higher levels of melatonin, you feel sleepier Sleep and Human Development How much sleep do we need?

Insomnia – difficulty falling and/or staying asleep o Most likely to be associated with depression and other medical conditions Narcolepsy – people can fall asleep at any time for a few seconds or minutes; always sleepy o Cataplexy – paralysis when you fall asleep; no muscle tone About half of the people who have narcolepsy also have cataplexy o Orexin – they don’t have specific structures in their body that produce orexin o No current cure for narcolepsy Sleep apnea – getting poor quality sleep and/or waking up a lot throughout the night o Symptoms occurring because airways are blocked o More common in people who are overweight Treatment lose weight air mask that you can wear that forces air into your airways Night Terrors – more of an issue for the people around them o A person will wake up; looks like their awake but they are in a state of consciousness o Most common in children; more so in boys Sleepwalking – in an altered state of consciousness o Most common in children o May include complex behaviors Driving Going online Dreaming Theory and psychology of dreams o What’s happening when we dream? Activation-synthesis theory – random activity that goes to the forebrain and the forebrain makes a story o Pons Brain activity o Forebrain Inputs into a story Role of the Forebrain o Damage eliminates dreaming Neurocognitive theory – dreams are more meaningful and mundane o Everyday preoccupations & repetitive o Cognitive capacities – children have different kinds of dreams than adults Children dream less and simpler dreams Why do we dream Involved in: o Reorganizing / consolidating memories Learning new strategies / behaviors o Helps us to process emotional memories o Coping – simulating threatening events Other States of Consciousness Hallucinations – when you experience perception in the absence of stimuli o As real as real to the people who are experiencing them Out of body / Near-death experiences o Perception, not reality. o There is no science to back this up, other than people saying that it happened o Their experiences often correlates with their beliefs and expectations Déjà vu o A feeling of extreme familiarity in the absence of any actual recognition o There is a part of your brain that “lights up” when something is familiar to you o Or it could be a memory that you’re not consciously aware of Hypnosis o There is an external force that provides the person with suggestions for changes in: Perception Thought/feelings Behaviors o First step is a relaxation induction technique o Can’t brainwash you – subliminal persuasion o Misconceptions Trance state – zombie like Unaware of surroundings Improves memory – it does result in an increased number of details recalls but its increases both accurate and inaccurate details. There is a law against using the “improved memory” from hypnosis. o Theories of Hypnosis Sociocognitive Theory – your experience of hypnosis depends on your beliefs and expectation; impacts whether or not you can be hypnotized People’s beliefs and expectations Highly suggestible(easy to hypnotize) / not suggestible(hard to hypnotize) Dissociation Theory – certain functions run our control and planning while other functions run our actions subconsciously; separates control functions from subconscious functions Separation of personality functions o Useful? Yes – used in combination with therapy Meditation o Concentrative meditation – focusing your attention on something specific; concentrating on breathing or an object or a word o Awareness meditation – free thought, whatever pops into your head is what you’ll ponder on o Purpose? Stress / spiritual growth / insight Changes for different cultures o Helpful? Yes o Why? Might be a piece of an overall treatment plan Chapter 6 Learning What is Learning? A relatively permanent change o In behavior (thoughts) Due to experience Classical Conditioning (CC) Learning o Stimuli and responses Pairing stimuli NS: Neutral Stimulus – something that has no ability to naturally elicit a response UCS: Unconditioned stimulus – normally, naturally elicits a response UCR: Unconditioned response – a normal response to the unconditioned stimulus CS: Conditioned stimulus – what the neutral stimulus comes at the end of the process; after learning CR: Conditioned Response – elicits response of the conditional stimulus Roommate with Easy button and airsoft-gun example: Neutral Stimulus? – easy button sound Unconditioned Stimulus? – being shot with airsoft gun Unconditioned Response? – saying ow, flinching, ect. Conditioned Stimulus? – easy button sound Conditioned Response? – flinching just from the sound; no shot Applications of CC Advertising o Pair positive USC’s with product; product is neutral stimulus Treatment of phobias o Pair feared stimuli with pleasurable stimuli Operant Conditioning (OC) Acquiring behaviors o Outcome / consequence Positive reinforcement - increasing the likelihood of a behavior by giving someone something o Give something good o More likely to do it again Negative reinforcement - increasing the likelihood of a behavior by taking something away o Remove something bad o More likely to do it again Positive punishment - decreasing the likelihood of a behavior by giving someone something o Give something bad o Less likely to do it again Negative punishment - decreasing the likelihood of a behavior by taking something away o Remove something good o Less likely to do something Only an example of one of these terms if it is effective Punishment Less effective then reinforcement and there are disadvantages Tells us what NOT to do, rather than what TO DO Anxiety o Impedes learning; harder to learn Subversive behavior – being sneaky o Punishment can encourage subversive behavior Model for aggressive behavior o Physical punishment Discipline (not punishment) o Communication Applications of OC Token economics – reinforcement is immediate & encouraged o Secondary reinforces Representation of the primary reinforces Ex) gold star or sticker and you can trade them in for primary reinforces o Primary reinforces What they really want Applied Behavioral Analysis (ABA) o An entire set of techniques that are based on operant conditioning procedures o Shaping – you have a tangent behavior that cannot be quickly accomplished EX) Children with autism – looking in someone’s eyes over time Combining CC & OC Two-process theory of anxiety o Starts with CC Fear of heights; bad experience OC o Avoid heights Negative reinforcement Maintains behavior Observational learning Learning – without instruction or reinforcement Observing aggressive behavior o Bobo doll study o Violent media Correlation designs Longitudinal designs Experimental designs o Violent media Some causal relationship with aggression At times, a major contribution Chapter 7 Memory Reconstructive (Not reproductive) -> Sensory -> Short-term -> Long-term -> Memory -> Memory -> Memory Loss Loss Short-Term Memory (STM) Limited duration & capacity [only 7 +/- 2 pieces of info] Decay and interference: o Retroactive inhibition: acquisition of new information interfering with the old information o Proactive Inhibition: old info interferes with acquisitions of new info Increase capacity of STM Chunking: grouping info together to remember it better o IBMSATMTVPHD – not so easy o IBM, SAT, MTV, PHD – easy o 12151873 vs 12, 15, 1873 Rehearsal: repeating info to retain it Maintenance: repeating the definition over and over to remember it Elaborate: relating the info to a familiar idea Levels of Processing Visual Auditory and visual Semantic o These go from shallow to deep Synesthesia Solomon Shereshevsky o Appeared to be no limit to amount of information could be held o Fivefold synesthesia (all sense activated) Long-Term Memory (LTM) Capacity and duration o May endure for decades or forever Permastore Long-Term -> explicit -> semantic, episodic Memory -> implicit -> Procedural, priming, conditioning, habituation Types of LTM Explicit memory o Conscious awareness Semantic memory: facts Episode memory: events Implicit memory o No conscious effect Procedural memory: know how memory Priming: ability to identify stimuli more quickly when you encounter similar stimuli Conditioning: body responding to something that happens Habituation: decrease in response to unimportant stimuli that has repeatedly happened 3 Memory Processes Encoding Storage Retrieval Encoding Attention Mnemonics – any type of memory aid or learning strategy;

They originally said “no,” but thy kept coming back and asking again. Some of the kids started to say “yes”. 58% - said “yes” 25% - after the researchers told them that the memory wasn’t true, the kids refused to realize that it never actually happened o Bias Sam Stone study – the teacher told her class that Sam Stone was a clumsy guy and that he was going to come to class tomorrow. When he came, we sat down, flipped through a book and then left. The researchers asked the kids if he destroyed the book. 46% of the 3 & 4 yr olds said yes 30% of the 5 & 6 yr olds said yes “Recovered Memories” Suggestive therapeutic techniques: guided imagery, hypnosis, dream interpretation o Induced false memories Chapter 9 Intelligence & IQ Testing What is Intelligence?
