Week 7 - Day 2 (Ch9 continued Observational Learning)

Quizlet: https://quizlet.com/_21l53z

Does watching others affect learning?

  • Teaching someone to perform a complex task requires more than reinforcing arbitrary correct behaviors
  • We learn many behaviors, including attitudes, through observation
  •  Observational learning
    • ooThe acquisition or modification of a behavior after exposure to at least one performance of that behavior
  • Observational learning is a powerful adaptive tool for humans and other animals

  • There are several ways that behavior, thoughts, and attitudes can be learned through observation

Memes

-

  • ooA unit of knowledge transmitted within a culture
  • ooAnalogous to genes
  • ooTransmission of learning at the cultural level

  • Memes can be conditioned through association or reinforcement, but are often learned by watching the behavior of other people
    • ooThrough social learning, some behaviors are passed along from one generation to the next
    • ooSocial learning in Japanese macaques
      • Particular species of monkeys in Japan
      • Group of researchers were going to study them
      • The researchers would toss them sweet potatoes
      • One day, one of the monkeys washed the sweet potato off in the ocean (none of the other monkeys knew to do that)
        • Eventually all of them did it through observation

Social Learning of Fear

  • Researchers observed that lab-reared monkeys were not afraid of snakes the way monkeys in the wild are
    • ooThis research demonstrated that animals’ fears can be learned through observation
    • ooMonkeys in the lab hadn’t seen the snakes, but also weren’t around other monkeys who had that fear response that they could pick up
  • Social forces play a role in fear-learning in humans, too
    • ooHearing something is dangerous
      • You are less likely to do it later
      • If you hear that an amusement park is dangerous, you might be scared to go there
    • ooSeeing another person’s fear response
      • Dean’s wife has a fear of roaches that she developed from watching her sister have extreme fear of roaches

  • Demonstration and Imitation
  •  Modeling : the imitation of behavior through observational learning
    • ooModeling is effective only if the observer is physically capable of imitating the behavior
      • If you only had one arm, it would be physically harder to imitate behavior
    • ooWe are much more likely to imitate attractive, high-status, or similar models
      • If you watch reality TV, you might think it’s okay to be more dramatic since those people have high status
    • ooOften occurs implicitly
  • Imitation is much less common in nonhuman animals than in humans
    • ooThe Japanese monkeys are an anomaly

Social Learning of Behavior

  •  Vicarious reinforcement
    • ooIs a model’s behavior reinforced or punished?
  •  Vicarious learning
    • ooLearning the consequences of an action by watching others being rewarded or punished for performing the action
      • Seeing someone else get a speeding ticket might make you drive safer
  • A key distinction in learning is between the acquisition of a behavior and its performance
  • In other words, learning a behavior does not necessarily lead to performing that behavior
  • What happens in the brain during imitation learning?
  •  Mirror neurons
    • ooNo one is certain of their exact function
    • ooMay serve as the basis of imitation learning
    • ooMay help us explain and predict others’ behavior
    • ooMay be the neural basis for empathy
      • Why is someone crying?
        • Probably because they’re sad
    • ooMay play a role in humans’ ability to communicate through language
    • ooWe are sure: mirror neurons track the behaviors of targets as those behaviors unfold over time
      • If you imitate someone, your same brain regions are active as the person doing the behavior
    • ooIn order to imitate someone, we have to know their intention
  •  Bandura’s observational studies
  • Bandura’s studies suggest that exposing children to violence may encourage them to act aggressively
  • Understanding these relationships has important, real-world applications
  • How does aggression between spouses influence children’s relationship styles?
    • ooIf children see their parents acting aggressive towards each other, how does that affect their relationships with their peers and then how does it affect their relationships down the road?
  • Does violent media increase aggressive behavior?
    • ooThere’s a lot of research that says yes
  • Does violent media increase violent behavior?
    • ooYES! YES! YES!
  • Violent media leads to long-term and short-term aggressive behavior (Anderson et al., 2003)

  • Even short periods of exposure to violent media lead to desensitization (Carnagey, Anderson, & Bushman, 2007)

  • Viewing habits at age 8 predict criminal activity and violent behavior at age 30 (Eron, 1987)

  • A meta-analysis of such studies suggests that, indeed, violent media increases the likelihood of aggression (Gentile, Saleem, & Anderson, 2007)
    • ooA lot of evidence that it impacts behavior
  • Does violent media increase violent behavior?
    • ooNO! NO! NO!
  • Competition, not violence, may have the greatest influence on aggressive behavior (Adachi & Willoughby, 2011)
  • Cooperative gameplay decreases aggressive cognitions (Schmierbach, 2010)
  • Cooperative gameplay also produces less physiological arousal (Carnagey, Anderson, & Bushman, 2007)
    • ooYou become less agitated when playing with others than by yourself
  • Gamers scored better on several measures of adjustment and risk-taking than non-gamers (Durkin & Barber, 2002)

Chapter 7 (part 1)

Thinking and intelligence

  • How would you define “thinking”
    • ooBookmark added at 27:20 in Audio 1
  • The field of psychology that focuses on thought is called cognitive psychology
  • Two components
    • ooBrain represents information
    • oo Thinking is the mental manipulation of these representations
  •  Cognition includes thinking and the understandings that result from thinking
  • Our thoughts consist of mental representations
  •  Analogical representations
    • ooMental representations of objects (caricatures, maps, etc)
  •  Symbolic representations
    • ooMost frequently used symbolic representations are concepts
    • oo Concept
      • Mental representation
      • Musical instruments
        • Guitar
          • Has six strings
        • Violin
          • Has four strings
        • Trumpet
          • Is blown into

All of these are played

Defining attributes

  • In this way of thinking about concepts, a category is characterized by a list of features that determine whether an object is a member
  • Bachelor
    • ooUnmarried and male
  • Not always clear
    • ooA sixteen year old boy
    • ooA man in his 30s who goes on several dates each week
    • ooA man in a relationship of 35 years who has never married
    • ooAre the above bachelors?

Prototype

  • Within each category, there is a best example - a prototype - for that category
  • Some category are more prototypical than others
    • ooThe prototypes are simply members we have encountered more often
