‭ rominent Approaches‬ P → ‭ Sigmund Freud, Erik Erikson, Karen Horney, Carl Jung, Jean Piaget.‬ ‭Understanding Theories:‬ ‭Psychoanalytic/Psychodynamic Theories.‬ ‭Psyche = The mind‬ ‭Characteristics of the Psychoanalytic Approach: This approach describes development as a‬ ‭primarily unconscious process which is heavily coloured by emotion. Psychoanalytic‬ ‭theorists believe that behavior is merely a surface characteristic and that to truly‬ ‭understand development we have to analyse symbolic meanings of behaviour and the deep‬ ‭inner workings of the mind. Early experience is also very important to development.‬ ‭__________________________________________________________________‬ ‭Feb 4. 2025‬ (‭ Tue-Feb-4)‬ ‭Sigmund Freud:‬‭He was a brain doctor. He had a patient‬‭with extreme pain in her legs and there‬ ‭was no reason for the pain, no injury or nerve disorder. He started listening to her and asking‬ ‭questions. it became clear that she was in love with her ill sister's husband. The woman was‬ ‭very conflicted. She didn't want her sister to die, but if she died, then she would get her‬ ‭husband.‬ ‭ ‬ ‭Freud's theory was born…the pain in her leg was not a result of pain but the result of‬ ‭the incapability to deal with the anguish of her thoughts. Her mind sent the pain to her‬ ‭body.‬ ‭‬ ‭Freud emphasized the importance of‬‭early childhood‬‭experiences‬‭shapes our‬ ‭personality and behaviour‬ ‭‬ ‭We are biological beings, naturally‬ ‭‬ ‭We are driven by instinct‬ ‭‬ ‭During childhood, we begin to become social beings as we learn how to manage our‬ ‭instincts and transform them into socially acceptable behaviours‬ ‭‬ ‭The‬‭type of parenting‬‭received is a very powerful‬‭impact of the child’s personality‬ ‭development‬ ‭‬ ‭Interaction between these three forces determine who we are‬ ‭○‬ ‭Id, Ego, Super-ego‬ ‭‬ ‭Id‬ ‭‬ ‭Basic and primal part of‬ ‭the personality, is the part‬ ‭of the self with which we‬ ‭are born‬ ‭‬ ‭Pleasure principle‬‭→ seek‬ ‭pleasure, avoid pain‬ ‭‬ ‭Biologically-driven and‬ ‭includes our instincts and‬ ‭drives‬ ‭‬ ‭Part of us that wants immediate gratification‬ ‭‬ ‭Later, it comes to house our deepest, often unacceptable desires,‬ ‭such as sex and aggression‬ ‭‬ ‭Determines whether something is good or bad, based off the way‬ ‭it‬‭feels‬‭good or bad‬ ‭‬ ‭Most basic part of the personality, wants instant gratification for‬ ‭our wants and needs‬ ‭‬ ‭If these aren’t met one becomes tense and anxious‬ ‭○‬ ‭Ex. woman wants her sister’s husband, sister is dying, but if‬ ‭she dies she gets to be with him‬ ‭‬ ‭Ego‬ ‭‬ ‭Deals with‬‭reality principle,‬‭trying to meet the desires‬‭of the id in‬ ‭a way that is socially acceptable‬ ‭‬ ‭This means delaying gratification, and helping to get rid of the‬ ‭tension the id feels if a desire is not met right away‬ ‭‬ ‭Recognizes other people‬‭have wants and needs too,‬‭and that‬ ‭being selfish is not always good for us in the long run‬ ‭‬ ‭Super-ego‬ ‭‬ ‭Develops last, and is‬‭based on morals and judgements‬‭about right‬ ‭and wrong‬ ‭‬ ‭Even though the superego and the ego may reach the same‬ ‭decision about something, the superego’s reason for, that‬ ‭decisions is more based on moral values, while the ego’s decision‬ ‭is based more on what others will think or what the consequences‬ ‭are‬ ‭○‬ ‭The are “dynamic” forces, which means that they interact‬ ‭‬ ‭Constant conflict - id wants instant gratification regardless of‬ ‭consequences, but superego tells us that we must behave in socially‬ ‭acceptable ways‬ ‭‬ ‭Ego has to satisfy the id without comprising rationality‬ ‭‬ ‭Healthy personality - strong ego that can negotiate between; satisfying‬ ‭the id without breaking socially acceptable behaviours that would upset‬ ‭the super-ego‬ ‭‬ ‭A person who is dominated by their id → narcissistic and impulsive‬ ‭‬ ‭A person who is dominated by their superego → controlled by feelings of‬ ‭guilt and deny themselves socially acceptable pleasures‬ ‭Defense mechanisms‬ ‭‬ ‭Psychological strategies that are unconsciously used to protect a person from anxiety‬ ‭arising from unacceptable thoughts or feelings‬ ‭‬ ‭Freud believed that much of the human mind was unconscious‬ ‭○‬ ‭Ego uses DM’s to distort‬ ‭reality to deal with‬ ‭troubling situations, for‬ ‭instance:‬ ‭‬ ‭Repressing‬ ‭memories and‬ ‭feelings → expelling them from a conscious mind‬ ‭‬ ‭Provide an outlet the repressed feelings, people often displaced their‬ ‭feelings onto other objects or people‬ ‭Denial‬ ‭‬ ‭Not accepting the truth or lying to oneself‬ ‭‬ ‭Thoughts such as “it won’t happen to me” or “you’re not leaving” or “I don’t have a‬ ‭problem with alcohol”‬ ‭Displacement‬ ‭‬ ‭Taking out frustrations on a safer target‬ ‭‬ ‭A person who is angry at a boss may take out their frustration at others when driving‬ ‭home or at a spouse upon arrival‬ ‭Projection‬ ‭‬ ‭When a person attributes theri unacceptable thoughts onto others‬ ‭‬ ‭If someone is frightened, for example, they accuse someone else of being afraid‬ ‭Repression‬ ‭‬ ‭To push the painful thoughts out of consciousness (in other words, think about‬ ‭something else)‬ ‭Regression‬ ‭‬ ‭Going back to a time when the world felt like a safer place, perhaps reverting to one’s‬ ‭childhood behaviours‬ ‭Sublimation‬ ‭‬ ‭Transforming unacceptable urges into more socially acceptable behaviours‬ ‭○‬ ‭Ex. a teenager who experiences strong sexual urges uses exercise to redirect‬ ‭those urges into more socially unacceptable behaviour.‬ ‭DEFENCE MECHANISMS‬‭: Psychological strategies that‬‭are unconsciously used to protect a‬ ‭person from anxiety arising from unacceptable thoughts or feelings.‬ ‭Freud's Psychosexual stages of development‬ ‭Freud believed that individuals progress through five stages of developments.‬ ‭Each stage is characterized by a specific focus of the libido (sexual urges/instincts)‬ ‭He felt that all life revolved around tension and pleasure; tension was the build up of sexual‬ ‭energy and pleasure was its release.‬ ‭Remember the whole Id thing - it wants INSTANT GRATIFICATION.. The ego and superego try to‬ ‭manage that…the whole psychosexual development thing is that gratifications of this urge‬ ‭focusses on different parts of the body as different stages.‬ ‭If individuals do not fully resolve the conflict at a given stage, they can become fixated, thus‬ ‭causing them to over- or under - indulge in that area in adulthood. (if you didn’t resolve your‬ ‭issue during childhood it could affect your adulthood).‬ ‭Erik Erikson‬ ‭‬ ‭Neo-Freudian (new) in the terms that he believed that individuals go through a series of‬ ‭stages in their personality development. During each stage, the person experiences a‬ ‭psychosocial crisis which could have a positive or negative outcome for personality‬ ‭ evelopment. Failure to successfully complete a stage can result in a reduced ability to‬ d ‭complete further stages and therefore a move unhealthy personality and sense of self.‬ ‭These stages however, can be resolved successfully at a later time‬ ‭‬ ‭He differed from Freud in that he factored societal factors into the progression through‬ ‭these stages and he felt that an individuals’ development did not stop at age 12 (Freud's‬ ‭last psychosexual stage - the Gential one - was 12+) but continued throughout their lives.‬ ‭He proposed and popularized the term‬‭Identity Crisis‬‭.‬ ‭…So what does that mean?‬ ‭According to the theory, there are 8 stages of life defined by a “crisis” – successful completion of‬ ‭each stage results in a healthy personality and the acquisition of basic virtues.‬‭Basic virtues‬‭. Are‬ ‭characteristic strengths which the ego can use to resolve subsequent‬ ‭______________________________________________________________________________‬ ‭Feb 6. 2025‬ ‭Karen Horney - Psychoanalytic social theory‬ ‭‬ ‭The theory is built on the assumption that social and cultural conditions, especially‬ ‭childhood experiences, are largely responsible for shaping personality.‬ ‭‬ ‭People who do not have their needs for love and affection satisfied during childhood‬ ‭develop basic hostility towards their parents and, as a councequence, suffer from basic‬ ‭anxiety.‬ ‭‬ ‭Horney theroized that people combat basic anxiety by adapting one of three‬ ‭fundemental styles of realating to others:‬ ‭○‬ ‭Moving toward people; stalking, co-depedancy‬ ‭○‬ ‭Moving against people; instigation between people, arguing; convincing yourself‬ ‭nobody wants you regardless of the invitation.‬ ‭○‬ ‭Moving away from people; Isolation, sabtouging relationships‬ ‭‬ ‭Most normal people use any of these modes of relating to people but nerotics are‬ ‭compelled to ridgely rely on only one (One really stands out and is an unhealthy‬ ‭pattern).‬ ‭Carl Jung‬ ‭‬ ‭Jung possessed that the unconscious consists of two layers‬ ‭‬ ‭The‬‭first layer‬‭called the‬‭“Personal unconscious”‬‭which is essentially the exact same‬ ‭thing as Frued (ID, Super ego) Temorirally forgotten information and repressed‬ ‭memories.‬ ‭‬ ‭The‬‭second layer‬‭called the‬‭“collective unconscious”‬‭,‬‭which is a level of unconscious‬ ‭shared with other members of the human species comprising latent memories from our‬ ‭ancestral and evolutionary past.‬ ‭‬ ‭Latent:‬‭lying dormant or hidden until circumstances‬‭are suitable for development or‬ ‭manifestation.‬ ‭Archetypes:‬ ‭‬ ‭According to Jung the human himd has innate characteristics “imprinted” on it as a‬ ‭result of evolution. These universal predispositions stem from our ancestral past.‬ ‭○‬ ‭E.g. Fear of the dark, for snakes and spiders‬ ‭‬ ‭However more important then isolated tendencies are those aspects of collective‬ ‭unconscious that have developed into separate sub-systems of the personality. Jung‬ ‭called these ancestral memories and images‬‭Archetypes‬‭.‬ ‭‬ ‭Archetypes are images and thoughts which have universal meaning across cultures‬ ‭which may show up in dreams, literature, are or religion.‬ ‭‬ ‭Jung believes symbols from different cultures are often very similar because they have‬ ‭emerged from archetypes shared by the whole human race. For Jung, our primitive past‬ ‭becomes the basis of the human psyche, directing and influencing present behaviour.‬ ‭______________________________________________________________________________‬ ‭February 7. 2025‬ ‭Behavioral and social cogtetive approach:‬ ‭The Behavioural Perspective:‬‭The behavioral perspective‬‭is the psychological approach that‬ ‭suggests that the keys to understanding development are observable behavior and external‬ ‭stimuli in the environment.‬ ‭classical conditioning:‬‭Classical conditioning theory‬‭helps us to understand how our responses‬ ‭to one situation become attached to new situations‬ ‭Operant conditioning:‬‭organisms learn to associate‬‭a behavior and its consequence , a pleasant‬ ‭consequence makes that behavior more likely to be repeated in the future.‬ ‭The law of effect:‬‭According to the law of effect,‬‭behaviors that are followed by consequences‬ ‭that are satisfying to the organism are more likely to be repeated, and behaviors that are‬ ‭followed by unpleasant consequences are less likely to be repeated.‬ ‭Social Cognitive Theory:‬‭the theory proposes that‬‭learning occurs in a social context. It takes‬ ‭into consideration the dynamic and reciprocal interaction of the person, environment, and their‬ ‭own behavior.‬ ‭Ivan Pavlov:‬‭classical conditioning‬ ‭B.F Skinner: operant conditioning‬ ‭In the long run positive reinforcement has batter impact in long run on repetition of behavior.‬ ‭‬ ‭Consequences of behavior determine the likelihood of that behavior happening away‬ ‭○‬ ‭Consequenses is not always negative‬ ‭Albert Bandura:‬‭moudeling‬ ‭‬ ‭Albert Bandura is an influentialsocial cognitive psychologist who is best known for the‬ ‭social learning theory - the concept of self-efficacy and his famous Bobo doll‬ ‭experiments‬ ‭‬ ‭He wondered why the same situation could generate different responses from different‬ ‭people or even the same person‬ ‭‬ ‭He proposed people are driven by external stimuli‬ ‭‬ ‭The model is visualized as a triangle - behavior factors Environmental factors ‬ ‭Personal factors‬ ‭○‬ ‭Nature oif person is then defined within triadic perspective‬ ‭BOBO DOLL EXPERIMENT‬ ‭‬ ‭Stage 1: Moudeling * -> relied on the kid watching someone do it first‬ ‭○‬ ‭Kids who saw an adult with the bobo doll added layers of violence‬ ‭○‬ ‭Kids who didnt see the model didnt add new abstract ways they just hit the doll‬ ‭not aggressively‬ ‭‬ ‭Stage 2: aggressive Arousel‬ ‭‬ ‭Stage 3: Test Delayed Imitiation‬ ‭Jean Piaget:‬ ‭‬ ‭Best known for the‬‭stages of cognitive development‬ ‭‬ ‭Schema, assimilation, and accommodation‬ ‭○‬ ‭The way we learn -> create -> distroy & cycle‬ ‭○‬ ‭Children are born with very basic mental structures all learning and knowlage is‬ ‭bassed on the biological mental structure -> evelution has set us up with basic‬ ‭structures to learn‬ ‭○‬ ‭Schema:‬‭basic building blocks of intelligent behavior‬‭and organizing knowledge‬ ‭‬ ‭Jean viewed intellectual groth process of adaptation:‬ ‭‬ ‭Assimilation‬‭: Using an existing schema to deal with‬‭new object or situation‬ ‭‬ ‭Accommodation:‬‭This happens when the existing schema‬‭(Knowladge) does not work,‬ ‭and needs to be changed to deal with a new object or situation.‬ ‭‬ ‭Equilibration:‬‭This is the force that moves development‬‭along. Piaget believed that‬ ‭cognitive development did not progress at a steady rate, but rather it leaps in bounds.‬ ‭○‬ ‭When a child's schemas can deal with most new information through‬ ‭assimilation. However, an unpleasant state of disequilibrium occurs when new‬ ‭information cannot be fitted into existing schemas (assimilation).‬ ‭○‬ ‭Equilibrium is the force which drives the learning process as we do not like‬ ‭frustrated and will seek and restore balance by mastering a new challenge‬ ‭(accommodation). Once the new information is acquired the process of‬ ‭assimilation with the new schema will continue until the next time we need to‬ ‭make an adjustment to it.‬ ‭Example:‬ ‭‬ ‭Assimilation: The boy sees a man with clown-like hair and shouts “clown” because his‬ ‭scheme associates that hair with a clown. -> the child's mistake was the attempt to‬ ‭assimilate‬ ‭‬ ‭Accommodation: the father re-teaches the child what clowns look like so his schema‬ ‭changes.‬ ‭______________________________________________________________________________‬ ‭Feb 10. 2025‬ ‭Piaget 4 stages of cognitive development:‬ ‭1.‬ ‭Sensorimotor:‬ ‭‬ ‭0-2 years of age‬ ‭‬ ‭During this stage, infants and toddlers acquire knowledge through sensory‬ ‭experiences and manipulating objects.‬ ‭‬ ‭Piaget believed that developing‬‭object permanence‬‭was an important element at‬ ‭this point of development -> doesnt solidify until the end of the stage.‬ ‭‬ ‭Object Permanence -> When you can distinguish an object or person in you‬ ‭mind/where they are for example: if the one year old wanted to play with the‬ ‭knife and you took it out of their site, they would forget about it vs. and three‬ ‭year old who would know that the knife was put in the other room and they can‬ ‭remember the knife.‬ ‭2.‬ ‭Pre-Operational stage:‬ ‭‬ ‭2-6 years old‬ ‭‬ ‭At this stage, kids learn through pretend play but still struggle with logic and‬ ‭taking the point of view from other people.‬ ‭‬ ‭They are‬‭egocentric‬‭and typically only recognize their‬‭own point of view (literally‬ ‭and figuratively).‬ ‭‬ ‭They don't understand the idea of conservation e.g. two glasses of juice same‬ ‭amount pored into different bowls tall and wide they would think one as more‬ ‭then the other.‬ ‭‬ ‭Conservation of substance -> toast can't turn back into bread‬ ‭‬ ‭Statements like “you mother is my wife” wouldn't register‬ ‭3.‬ ‭Concrete Operational Stage:‬ ‭‬ ‭7-12 years old‬ ‭‬ ‭More logical thinking but logic is rigid‬ ‭‬ ‭Struggle with abstract and hypothetical concepts‬ ‭‬ ‭Less egocentric -> thinking how others think and feel‬ ‭‬ ‭Begin to understand that thoughts are unique to them‬ ‭4.‬ ‭Formal Operational stage:‬ ‭‬ ‭12 years old-adult‬ ‭‬ ‭Increasing logic and the ability to reasoning, understanding, and abstract thinking‬ ‭‬ ‭People become capable of seeing multiple solutions to problem -> more‬ ‭scientifically and can draw conclusions.‬ ‭Lev Vygotsky:‬ ‭‬ ‭Social Development Theory: a sociocultural cognitive theory that emphasizes‬ ‭developmental analysis, the role of language, and social relations.‬ ‭‬ ‭Learning is a necessary and universal aspect of the process of developing culturally‬ ‭organized, specifically human psychological function‬ ‭‬ ‭Social learning‬‭proceeds‬‭development‬ ‭‬ ‭social interactions drive cognitive complexity -> Piaget thinks the opposite‬ ‭○‬ ‭Two main principles:‬ ‭‬ ‭More Knowledgeable Other‬ ‭‬ ‭The more knowledge other is anyone that has a better‬ ‭understanding or higher knowledge than the learner‬ ‭‬ ‭Vygotsky believes there has to be a more knowledgeable other‬ ‭‬ ‭Zone of proximal development‬ ‭‬ ‭There is a gap between what a child already knows how to do and‬ ‭what a child can't possibly do even with help -> that zone is where‬ ‭development and learning happens‬ ‭The Zone of proximal development is the distance between a students ability to perform task‬ ‭under adult / and or peer collaboration and student’s ability solving the problem indipendantly.‬ ‭According to Vygotsky, learning occurred in this zone.‬ ‭Vygotsky focused on the connections between people and the sociocultural context in which‬ ‭they act and interact and share experiences. According to Vygotsky, humans use tools that‬ ‭develop from a culture, such as speech and writing, to interact with their social environments.‬ ‭Initially children develop these tools to serve solely as social functions, ways to communicate‬ ‭needs. Vygotsky believed that the internalization of these tools led to higher thinking skills.‬ ‭______________________________________________________________________________‬ ‭Feb 11. 2025‬ ‭Psychodynamic theorists:‬ ‭‬ ‭Freud‬ ‭‬ ‭Erikson‬ ‭‬ ‭Horney‬ ‭‬ ‭Jung‬ ‭Behaviourist theorists:‬ ‭‬ ‭Pavlov‬ ‭‬ ‭Skinner‬ ‭‬ ‭Bandura‬ ‭Cognitive Theorists:‬ ‭‬ ‭Piaget‬ ‭‬ ‭Vygotsky‬ ‭Humanists‬ ‭‬ ‭Maslow‬ ‭‬ ‭Rogers‬ ‭Humanists‬ ‭Abraham Maslow‬ ‭‬ ‭One of the founders of‬ ‭humanist psychology‬ ‭‬ ‭He focuses on what makes‬ ‭people happy and functional‬ ‭-> what gets in the way of‬ ‭them being happy‬ ‭‬ ‭Best known for Hierarchy Of‬ ‭Needs‬ ‭‬ ‭He wanted to understand what‬ ‭motivates people -> behaviour is the result of motivation‬ ‭‬ ‭He believed that people possess a set of motivation systems unrelated to rewards or‬ ‭unconscious desires‬ ‭‬ ‭In 1943 he stated that people are motivated to achieve certain needs, and that some‬ ‭needs take precedence over others.‬ ‭Carl Rogers‬ ‭‬ ‭Was a humanistic psychologist who agreed with the main assumptions of Abraham‬ ‭Maslow.‬ ‭‬ ‭However, he added that for a person to “grow”, they need an environment that provides‬ ‭them with genuineness (openness and self-disclosure), acceptance (being seen with‬ ‭unconditional positive regard), and emotath (being listened to and understood).‬ ‭Congruence & Incongruity‬ ‭‬ ‭Rogers believed that‬ ‭actualization required the‬ ‭management of congruency.‬ ‭Congruence is the relationship‬ ‭between a person's ideal self as‬ ‭determined by self-selected‬ ‭descriptors. Incongruity is the‬ ‭gap between the real self (the “I‬ ‭Am”) and the ideal self (the “I‬ ‭Should Be”).‬ ‭→ His idea of therapy is still prominent in therapy ←‬ ‭Seminar:‬ ‭Childhood Memory‬ ‭‬ ‭Learning to ride a bike‬ ‭‬ ‭Initially struggled, kept falling, felt frustrated‬ ‭‬ ‭Parents encouraged me to keep trying‬ ‭‬ ‭Eventually succeeded, felt proud and excited‬ ‭1. Psychosocial Theory (Erik Erikson – Industry vs. Inferiority)‬ ‭‬ ‭Middle and late childhood (ages 6-11)‬‭focuses on developing‬‭competence (self-efficacy)‬ ‭‬ ‭Success in learning a new skill (riding a bike) contributed to a sense of industry‬ ‭‬ ‭Parental encouragement played a role in boosting confidence‬ ‭‬ ‭If I had failed or received discouragement, I might have developed feelings of‬ ‭inferiority‬ ‭2. Behavioral Theory (B.F. Skinner – Operant Conditioning)‬ ‭‬ ‭Positive reinforcement:‬‭Praise from parents reinforced‬‭the behavior of trying again‬ ‭‬ ‭Negative reinforcement: Falling was an aversive‬‭consequence‬‭that led to adjusting‬ ‭balance‬ ‭‬ ‭Law of effect: Repeated successful attempts strengthened the behavior of biking‬ ‭independently‬ ‭‬ ‭Modeling‬‭(Albert Bandura’s Social Learning Theory):‬‭Watching my brother ride helped‬ ‭me learn through observation‬ ‭3.

Beagle (his boat).‬ ‭-‬ ‭These islands have species found in no other part of the world, though similar ones exist‬ ‭on the west coast of South America.‬ ‭-‬ ‭Darwin was intrigued by the fact that the birds were slightly different from one island to‬ ‭another.‬ ‭-‬ ‭He realized that the key to why this difference existed was connected with the fact that‬ ‭the various species live in different kinds of environments.‬ ‭Darwin's Finches‬ ‭‬ ‭Darwin identified 13 species of Finches in the Galapagos island chain.‬ ‭‬ ‭This was puzzling because he only knew about one species of this bird on the mainland‬ ‭of South America where they had all presumably originated.‬ ‭‬ ‭He observed that the Galapagos specifies differently from each other in beak size and‬ ‭shape.‬ ‭Adaptive Radiation‬ ‭‬ ‭He also noted that the beak varieties were associated with diets based on different‬ ‭foods.‬ ‭‬ ‭He concluded that when the original South American Finches reached the islands, they‬ ‭dispersed to different environments where they had to adapt to different conditions.‬ ‭‬ ‭Over many generations, they changed anatomically in ways that allowed them to get‬ ‭enough food and survive to reproduce.‬ ‭Evolution relies on reproduction.‬ ‭*Birds can't change their shape over the span of their life.‬ ‭Descent with Modification‬ ‭Darwin ame to understand that any population consists of individuals that are all slightly‬ ‭different from one another.‬ T‭ hose individuals having a variation that give them an advantage in staying alive long enough to‬ ‭successfully reproduce are the ones that pass on their traits more frequently to the next‬ ‭generation.‬ ‭…Their traits become more common and the population evolves. Darwin called this‬‭descent‬ ‭with modification‬‭.‬ ‭Natural Selection‬ ‭‬ ‭Among the birds that ended up in arid environments, the ones with beaks better suited‬ ‭for eating cactus got more food.‬ ‭‬ ‭Those with beak shapes that were better suited to getting nectar from flowers or eating‬ ‭hard seeds in other environments were at an advantage there‬ ‭‬ ‭As a result, they were in better cognition to mate.‬ ‭*It is nature that is selecting, not the animal itself.‬ ‭* Nature selected the best adopted varieties to survive and to reproduce. This process has come‬ ‭to be known as‬‭natural selection‬‭.‬ ‭Darwin did not believe that the environment was reducing the variation within the finch‬ ‭population. He correctly thought that the variation already existed an tha nature just selected‬ ‭for the most suitable eas shape and against less useful ones.‬ ‭Malthusian Catastrophes‬ ‭‬ ‭In 1798, Thomas Malthus, an English clergyman and pioneer economist, published an‬ ‭Essay on the Principles of Population.‬ ‭‬ ‭In it he observed that human populations will double every 25 years unless they are kept‬ ‭in check by limits in food supply.‬ ‭*‭S‬ urvival of the Fittest‬ ‭‬ ‭Darwin read Malthus’ essay and came to realize that all plant and animal populations‬ ‭have this same potential to rapidly increase their numbers unless they are consistently‬ ‭kept in check by predators, diseases, and limitations in food, water, and other resources‬ ‭that are essential for survival.‬ ‭‬ ‭This fact was key to his understanding of the process of natural selection.‬ ‭‬ ‭Darwin realized that the most fit individuals in a population are the ones that are least‬ ‭likely to die of starvation and, therefore, are most likely to pass on their traits to the next‬ ‭generation.‬ ‭ HO IS THE ‘FITTEST’?‬ W ‭As Darwin believed, it was not necessarily the strongest or most intelligent members of a‬ ‭species who have the best chance to survive, but rather it is those who are most responsive to‬ ‭change and best suited for their environment.‬ ‭What traits do you think make one better suited than others?‬ ‭Evolutionary Psychology:‬‭Is an approach that emphasizes‬‭the importance of adaptation,‬ ‭reproduction, and survival of the fittest in explaining behavior.‬ ‭David Buss, who teaches psychology at the Uni of texas, reasons that just ad evolution shapes‬ ‭humans’ physical features, such as body shape and height, it also influences how we make deci‬ ‭how aggressive we are our fears and our mating patterns.‬ ‭Decent with modification‬ ‭______________________________________________________________________________‬ (‭ Wed-Feb-19)‬ ‭ ey Arguments and Ideas of Evolutionary Psychology‬ K ‭1.‬ ‭The claim that the cognitive mechanisms that are underlying our behaviour are‬ ‭adaptations.‬ ‭2.‬ ‭The idea that they cannot be studied directly, for example, through observation of the‬ ‭brain or our overt behavior, but have to be discovered by ,means of a method known as‬
