Chapter 1: Psychology and Scientific Thinking What is Psychology? Science vs. Intuition  William James (1842-1910)- founder of American psychology  Difficult to study, simple explanations of behavior are few and far between  Hows/whys of human behavior Psychology and Levels of Analysis  Not easy to define  Psychology- scientific study of the mind, brain and behavior  Spans multiple levels of analysis o Levels of analysis- rungs on a ladder of analysis, with lower levels tied mostly closely to biological influences and higher levels tied most closely to social influences o Low Rungs  Molecules and brain structures  The brain o High Rungs  Thoughts, feelings and emotions/social and cultural influences  The mind  The mind is the brain in action  Some believe biological factors are critical for understanding behavior o Actions of the brain and it’s billion nerve cells  Others believe social factors are critical for understanding behavior o Parenting, peer influences and culture  Both are essential for a complete understanding of psychology What Makes Psychology Distinctive- and Fascinating  Psychology is unique from other sciences  Challenges make the study of the mind, brain and behavior complex o Contributes to mysteries that are yet to be solved  5 challenges of Psych: o Human behavior is hard to predict  Multiply determined- caused by many factors  Behaviors are difficult to predict  Skeptical of single-variable explanations of behavior  Widespread in popular psychology o Ex. Violence  Tempting to say it’s caused by a single factor like poverty, bad upbringing or genes  Behaviors are almost surely due to many factors o Psychological influences are rarely independent of each other  Difficult to find the real cause  Ex. Anorexia nervosa  If a woman is a perfectionist she’s likely to also be anxious, exercise a lot, be overly concerned with her body image, watch tv programs that feature thin models, etc. o People differ from each other in thinking, emotion, personality and behavior  Individual differences- variations among people in their thinking, emotions, personality and behavior  Make psych hard because they make it hard to come up with explanations of behaviors that apply to everyone  Make psych exciting because people we think we understand surprise us with their reactions o People often influence each other  Make it difficult to pin down what causes what  Ex. Extroverted people make those around them more outgoing  Reciprocal determinism- mutually influence each other’s behaviors o Behaviors are shaped by cultures  Place limits on the generalizations that psychologists can draw on human nature  Ex. European-American and Chinese looking at lion picture o European-Americans looked at the tiger o Chinese looked at surroundings Why We Can’t Always Trust Our Common Sense  Intuitive understanding is frequently wrong o Safety in numbers o More people present in a fire, LESS likely one will help  Naïve realism- belief that we see the world precisely as it is o Seeing is believing  See a truck coming at 85 mph, we move out of the way o We should trust our perceptions  Appearances can sometimes be deceiving o Earth appears flat  Trip us when we evaluate ourselves and others o Common sense- people who don’t share our political views are biased and we’re objective o Psych research- all of us evaluate political issues in a biased fashion  Sometimes believing is seeing o Beliefs shape the perception of the world  Common sense isn’t always wrong o Judgment on a person when we meet them are right more often than not  Common sense is also helpful for generating hypothesis for experiments  Learning when and when not to trust common sense helps us make better decisions Psychology as a Science  Science- a systematic approach to evidence o Set of attitudes and skills designed to prevent us from fooling ourselves  Empiricism- premise that knowledge should initially be acquired through observation o Observation is a rough starting point for obtaining psychological knowledge o Science refines observations through experiments to determine their accuracy  Majority of general public doubts that psych is a true science  Many think its just asking why they do what they do to understand behaviors  Scientific psychologists rely on systematic research methods o Talking to people is only one component  Many think its familiar to all of us o Memory, learning, love, sleep and dreams, and personality o We assume its easy  Psych can be harder than biology, chemistry and physics  Scientific theory- explanation for a large number of findings in the natural world o Offers an account that ties multiple findings together in one pretty package o General explanations  Hypothesis- testable prediction derived from a scientific theory o Specific predictions derived from those explanations  Scientists can accept, reject or revise the theory that generated the hypothesis  Misconception 1: a theory explains one specific event  Misconception 2: a theory is just an educated guess  All general scientific explanations of how the world works are theories o Big Bang Theory  Galaxies are rushing away from each other  Universe has background radiation from an explotion  Oldest galaxies originate around time of big bang  Theories can’t be proved o A better explanation might come along  Scientists are biased; we’re human  Confirmation bias- tendency to seek out evidence that supports our hypothesis and deny, dismiss or distort evidence that contradicts them o Scientists adopt procedural safeguards against errors to protect from bias o Seek and ye shall find o Extends to daily life  Friends, romance and politics o Our side almost always seems right and the other side wrong  Belief perseverance- tendency to stick to our initial beliefs even when evidence contradicts them o Don’t confuse me with the facts Metaphysical Claims: The Boundaries of Science  Metaphysical Claims- assertion about the world that isn’t testable o Existence of God, the soul and the afterlife  Testable claims fall within the province of science  Untestable claims don’t  No conflict between science and the vast majority of religious views Recognizing That We Might Be Wrong  Science is a continually and revising process o Strength as a method of inquiry o Acquire knowledge slowly and in small bits of pieces o Always open to revision  Prescription for humility o Scientists never try to “prove” their theory o Use terms such as suggests, appears, and raises the possibility that to allow scientists room for revision The Amazing Growth of Popular Psychology  Popular psychology industry is growing o Positive- public has access to psychological knowledge o Negative- misinformation explosion What is Pseudoscience?  Pseudoscience- set of claims that seems scientific but isn’t o Lacks the safeguards against confirmation bias and belief perseverance that characterize science  Must be careful to distinguish pseudoscientific claims from metaphysical claims o Metaphysical- cannot be tested; lie outside the realm of science o Pseudoscientific- can be tested  Pseudoscientific and other questionable beliefs are widespread o 41% believe in ESP o 30% in ghosts/telepathy o 25% in astrology  Warning signs of pseudoscience o Overuse of ad hoc immunizing hypotheses- escape hatch or loophole that defenders of a theory use to protect their theory from falsification  Psychics saying the “vibes” of the experimenters are interfering with their psychic powers o Lack of self correction-  Astrology remains the same as it did 4,000 years ago despite discovery of outer planets in the solar system o Overreliance on anecdotes-  “The plural of anecdote isn’t fact”  I know a person who…  Pseudoscience relies heavily on anecdotal evidence  Extremely difficult to interpret as evidence  We’re drawn to pseudoscience because our brains are predisposed to make order out of disorder and find sense in nonsense o Helps us simplify the complex world we live in o Without it we’d be overwhelmed by endless streams of info that we don’t have the time or ability to process  Can sometimes cause us to perceive meaningful patterns when they’re not there Why do we Perceive Patterns Even When They Don’t Exist?  Patternicity- the tendency to detect meaningful patterns in random stimuli  Stems from adaptive tendency o Eating a food that makes us sick  we avoid that food for a while o “Better safe than sorry”  Tend to attribute paranormal significance to coincidences that are due to chance o Lincoln-Kennedy conspiracy  Leads us to embrace conspiracy theories  Tendency to see meaningful images in meaningless visual stimuli o Face of a “man” on the moon  Pseudoscience is motivational o We believe because we want to believe o “Hope strings eternal” o Give us comfort  Offer a sense of control over an unpredictable world o Drawn when we’re going to lose control of our world  Terror management theory- theory proposing that our awareness of our death leaves us with an underlying sense of terror with which we cope by adopting reassuring cultural worldviews o Reassure us that our lives possess a broader meaning and purpose o Comforting to many of us o Imply the existence of a dimension beyond our own  Logical fallacies- traps in thinking that can lead to mistaken conclusions o Scientific thinking requires us to cast aside our intuitions  Emotional reasoning fallacy- error of using our emotions as guides for evaluating the validity of a claim o Findings that challenge our beliefs make us angry o Findings that support our beliefs make us happy o Can’t assume that because a claim makes us uncomfortable that it’s wrong o Must keep an open mind to the data  Bandwagon fallacy- error of assuming that a claim is correct because many people believe it o Popular opinion isn’t a popular guide to the accuracy of an assertion  Sun revolving around earth  Not me fallacy- error of believing that we’re immune from errors in thinking that afflict other people o Can make us believe we don’t require the safeguards of the scientific method o Many pseudoscientists are certain their claims are right and uncontaminated by mistakes in their thinking  Don’t bother to conduct scientific studies to test these claims  Other fallacies: o Either or fallacy- error of framing a question as though we can only answer it in one of two extreme ways o Appeal to authority fallacy- error of accepting a claim merely because an authority figure endorses it o Genetic fallacy- error of confusing the correctness of a belief with its origins or genesis o Argument from antiquity fallacy- error of assuming a belief must be valid because it’s been around for a long time o Argument from adverse consequences fallacy- error of confusing the validity of an idea with its potential real-world consequences o Appeal to ignorance fallacy- error of assuming that a claim must be true because no one has shown it to be false o Naturalistic fallacy- error of interfering a moral judgment from a scientific fact o Hasty generalization fallacy- error of drawing a conclusion on the basis of insufficient evidence o Circular reasoning fallacy-error of basing a claim on the same claim reworded in slightly different terms  Bias blind spot- most people are unaware of their biases but keenly aware of them in others o Watching a debate o Highly intelligent people The Dangers of Pseudoscience: Why Should We Care?  Opportunity Cost: What We Give Up o Pseudoscientific treatments for mental disorders can lead people to forgo opportunities to seek effective treatments o Cause people to forfeit a treatment that actually works  Ex. Depression and anxiety  Some treatments include acupuncture, laugh treatment and energy therapy  Instead of cognitive-behavioral therapy  Direct harm o Pseudoscientific treatments sometimes do dreadful harm  Cause psychological or physical damage, or even death  Inability to thing scientifically as citizens o We can apply scientific thinking skills to all aspects of our lives Scientific Thinking: Distinguishing Fact From Fiction Scientific Skepticism  Scientific skepticism- approach of evaluating all claims with an open mind but insisting on persuasive evidence before accepting them  Adopt 2 attitudes o A willingness to keep an open mind to all claims o A willingness to accept claims only after researchers have subjected them to careful scientific tests  Skeptics are willing to change their mind when faced with evidence that challenges their preconception o Only when the evidence is persuasive  Motto: “show me”  Unwilling to accept claims based off authority alone o Evaluate claims on their own and refuse to accept them until they meet a high standard of evidence A Basic Framework for Scientific Thinking  Critical thinking- set of skills for evaluating all claims in an open minded and careful fashion o Scientific thinking  6 Principles of Scientific Thinking: o Ruling out Rival Hypothesis-  We usually only hear about 1 explanation when there are more than one  The media only reports one explanation  Must rule out other explanations before deciding on the one given o Correlation Isn’t Causation-  When 2 things are associated with each other, one thing must cause the other  Correlational designs don’t permit casual inferences  Correlation isn’t causation  Correlation-causation fallacy- error of assuming because one thing is associated with another, it must cause the other  Variable- anything that can vary  Because 2 things are correlated doesn’t mean one causes the other  A  B; possible that A causes B  B  A; possible that B causes A  A  C ; C causes both A and B  B o Known as third variable problem o Can lead us to conclude that A and B are casually related to each other when they’re not o Falsifiability-  Falsifiable- capable of being disproved  If a theory isn’t falsifiable, it can’t be tested  Theory can be proven false if there was evidence against it  Proponent must state clearly in advance which findings would count as evidence for and against the claim  Key implication is that a theory that explains everything, explains nothing o Replicability- when a study’s findings are able to be duplicated, ideally by independent investigators  If the findings can’t be replicated, the original findings were by chance  Shouldn’ t place too much stock in findings until it’s been replicated  Awareness of replicating comes from not being able to repeat well-established findings in psychology  Decline effect- fact that size of certain psychological findings appears to be shrinking over time  Replications aren’t duplications of the original researchers’ method  Introduce minor variations to the original design  The more we can replicate our findings using different participants in different settings, the more confidence we can place in those findings  The media is more likely to promote positive findings than failures  Investigators must replicate the results to increase our confidence in them  Whenever we evaluate a psychological claim, we should ask ourselves whether independent investigators have replicated the findings that support this claim, otherwise the findings might be a one time only fluke o Extraordinary Claims Require Extraordinary Evidence  The more a claim contradicts what we already know, the more persuasive the evidence for this claim must be before we accept it  Alien abductions  Whenever we evaluate psychological claim, we should ask ourselves whether this claim runs counter to many things we know already and whether the evidence is as extraordinary as the claim o Occam’s Razor  Principle of Parsimony  Logical simplicity  If there are two explanations for a phenomenon, we should select the simpler one  Use Occam’s razor to “shave off” needlessly complicated evidence  KISS- keep it simple stupid Psychology’s Past and Present: What a Long, Strange Trip It’s Been Psychology’s Early History  Difficult to distinguish from philosophy  Didn’t conduct experimental research o Sat and contemplated the human mind from an armchair o Relied on common sense  Wilhelm Wundt- o Developed the first full-fledged psychological lab o Investigations focused on simple questions o Used a combination of experimental methods o Introspection- method by which trained observers carefully reflect and report on their mental experiences  Psychology needed to bread free from spiritualism o Did so by creating psychology of human error and self-deception o Began asking how people can fool themselves into believing things that aren’t supported by evidence The Great Theoretical Frameworks of Psychology  Structuralism- elements of the mind o Edward Bradford Titchener o Structuralism- school of psychology aimed to identify the basic elements of psychological experience o Creating a comprehensive map of the elements of consciousness  Believed consisted of sensations, images and feelings o Problems  Introspectionists often disagreed on their subjective reports  Participants engaged in imageless thought- thinking unaccompanied by conscious experience  Couldn’t describe what came to mind when asked to add 10 + 5 o Emphasized the importance of systematic observation  Functionalism- Psychology Meets Darwin o Functionalism- school of psychology that aimed to understand the adaptive purposes of psychological characteristics  Thoughts, feelings and behaviors o Asked “why?” questions o William James  Wrote Principles of Psychology  Coined term “stream of consciousness” o Influenced by Darwin’s theory of natural selection  Natural selection- principle that organisms that possess adaptations survive and reproduce at a higher rate than do other organisms  Physical and behavioral characteristics evolved because they increased the chances of their survival and reproduction  Behaviorism- The Laws of Learning o Psychological science must be objective, not subjective o John B. Watson  Founder of behaviorism- school of psychology that focuses on uncovering the general laws of learning by looking at observable behavior o Psychology should aspire to uncover the general laws of learning that explain all behaviors o All behaviors are the products of a handful of basic learning principles o We don’t need to look inside the individual, we can learn by looking on the outside  Rewards and punishments delivered by the environment o Human mind is a black box- we know what goes in it and what comes out, but we don’t need to worry about what happens between the inputs and the outputs  Behaviorism = black box psychology  Cognitivism- Opening the Black Box o Cognition- mental processes involved in different aspects of thinking o Cognitive psychology- school of psychology that proposes that thinking is central to understanding behavior o Must understand how people evaluate information to grasp the causes of their behavior o We learn by insight- grasping the underlying nature of problems o Cognitive neuroscience- relatively new field of psychology that examines the relation between brain functioning and thinking  Psychoanalysis- The Depth of the Unconscious o Sigmund Freud o Psychoanalysis- school of psychology, founded by Sigmund Freud, that focuses on internal psychological processes of which we’re unaware  Impulses, thoughts and memories o Primary influences on behavior aren’t forces outside the organism, but unconscious drives o Goal of psychoanalyst is to decode the symbolic meaning of our slips of the tongue (Freudian slips), dreams and psychological symptoms o Psychoanalysts contend they can get to the bottom of our deep- seated psychological conflicts o Place emphasis on the role of childhood experience o Core of our personality is formed in the first few years of life o Some critics say psychoanalysis has slowed the progress of scientific psychology because it focuses heavily on unconscious processes that are difficult to falsify o Great deal has held up well in research  Much important mental processing happens outside conscious awareness The Multifaceted World of Modern Psychology  Psychology has grown since its beginnings o 500,000 psychologists world wide  100,000 in US alone o American Psychological Association is the world’s largest association of psychologists  150,000+ members  150 in 1900 o Association for Psychological Science has over 23,000 members  Types of Psychologists o Clinical psychologist-  Perform assessments, diagnosis and treatment of mental disorders  Conduct research on people with mental disorders  Work in colleges and universities, mental health centers and private practices o Counseling psychologist-  Work with people experiencing temporary or relatively self- contained life problems  Marital conflict, sexual difficulties, occupational stressors or career uncertainty  Work in counseling centers, hospitals and private practice o School psychologist-  Work with teachers, parents and children to remedy students’ behavioral, emotional and learning difficulties o Developmental psychologist-  Study how and why people change overtime  Conduct research on infants’, children’s and sometimes adults’ and elderly people’s emotional, physiological and cognitive processes and how these change with age o Experimental psychologist-  Use research methods to study memory, language, thinking and social behaviors of humans  Work primarily in research settings o Biological psychologist-  Examine the physiological bases of behavior in animals and humans  Work in research settings o Forensic psychologist-  Work in prisons, jails and other settings to assess and diagnose inmates and assist with their rehabilitation and treatment  Others conduct research on eyewitness testimony or jury decision making  Typically hold degrees in clinical or counseling psychology o Industrial-Organizational Psychologists-  Work in companies and businesses to help select productive employees, evaluate performance, examine the effects of different working and living conditions on people’s behavior (environmental psychologist)  Design equipment to maximize employee performance and minimize accidents (called human factors or engineering psychologists) The Great Debates of Psychology  The Nature-Nurture Debate o Are our behaviors attributable mostly to our genes (nature) or our rearing environments (nurture)? o Controversial in intelligence, personality and psychopathology (mental illness) o Intelligence, personality, interests and many mental illnesses are influenced by genes o Both genes and environment play a role in human behavior o Evolutionary psychology- discipline that applies Darwin’s theory of natural selection to human and animal behavior  Memory, emotion and personality serve key adaptive functions  Help organisms survive and reproduce  Natural selection favored certain kinds of mental traits  Fitness- extent to which a trait increases the chances that organisms that possess it will survive and reproduce at a higher rate than competitors who lack it  More fit organisms pass their traits to later generations  Many of its predictions are difficult to falsify  Challenging to determine the evolutionary functions of behavior because it doesn’t leave behind fossils  The Free Will-Determinism Debate o To what extent are our behaviors freely selected rather than caused by factors outside our control? o Some psychologists agree that we all possess free will o Others maintain that free will is an illusion  Our sense of free will stems from the fact that we aren’t consciously aware of the thousands of subtle environmental influences impinging on our behavior at any given moment  We conclude that we’re free because we don’t realize all of the influences acting on our behavior o Some argue that our behaviors are generated automatically- without conscious awareness How Psychology Affects Our Lives  Psychological science and scientific thinking offer important applications for a variety of aspects of everyday life  Basic research- research examining how the mind works  Applied research- research examining how we can use basic research to solve real-world problems  Few people are aware of the impact of psychology on their everyday lives o It’s found its way into many aspects of society than we realize  Insist on evidence
