cognitive

Cards (20)

  • What are the basic assumptions of the cognitive approach?
    • The mind actively processes information from our senses
    • Between stimulus and response are complex mental processes that can be studied scientifically
    • Humans can be seen as data-processing systems
    • The workings of a computer and the human mind are alike - encode + store info and have outputs
  • What is the definition of an inference?
    process of drawing conclusions about general patterns of behaviour from specific observations
  • What is the definition of a schema?
    a cognitive framework or concept that helps organize and interpret information
  • What are the positives of a schema?
    • Increases memory - organize current knowledge
    • Help development
  • What are the negatives of a schema?
    • Contributes to stereotypes
    • Dysfunction leads to emotions such as shame, anger and sadness
  • Outline Bartlett's War of the Ghosts experiment
    The experimenter tells 20 students a Native American ghost story with unusual features and asks them to recall on random occasions
    Results:
    • Shortened story
    • Fabricated details
    • Rationalized
  • What are the weakness' of the Bartlett War of the Ghosts experiment
    • Doesn't use experimental controls - asked to recall on random occasions
    • Subjective to experimenter's opinion
    • Low ecological validity
  • How does Bartlett's War of Ghosts experiment support schemas?
    Highlights how peoples organise memories to rationalise what is stored and interpret it in a way that is understandable even if there are fabricated details
  • What are the differences between theoretical and computer models?
    Theoretical models are diagrammatic representation of steps in internal mental processes whereas computer models are software simulations of internal mental processes
  • What is the definition of internal mental processes?
    information received from our senses is processed by the brain and how we process it affects how we behave
  • What are the 5 mental processes?
    • Perception - process by which we take in + make sense of info
    • Attention - process by which we focus on particular source of info
    • Memory - process by which we retain + recall info
    • Language - use of mental symbols to represent info to help communicate
    • Thinking - process by which we manipulate info in mind to reason, solve problems and make decisions
  • What is the definition of inattention?
    an internal mental process which explains why we miss out on details
  • What is the definition of the theoretical model (and example)?
    An abstract model that states something works that way
    • information-processing model
  • What is the definition of a computer model (and example)?
    concrete programs of inputting and outputting
    • the enigma encoder
  • What is the definition of cognitive neuroscience?
    study of the living brain and biological structures that underpin cognitive processes and form our behaviour
  • How does cognitive neuroscience work?
    the use of non-invasive neuroimaging techniques such as fMRI helps psychologists understand how the brain supports different cognitive activities and emotions by showing what parts of the brain became active in specific circumstances
  • Outline some findings of cognitive neuroscience
    Tulving et al. - found episodic and semantic memories in the prefrontal cortex (prefrontal cortex = memory + response)
    Burnett et al. - found that when people feel guilty, several brain regions are active including the prefrontal cortex (related to social emotions)
  • What is in the future of cognitive neuroscience?
    • Brain mapping - measures brain waves of the subject when experiencing a stimulus previously experienced
    This means criminals will be found to have a memory of the accused stimuli
  • What are the strengths of cognitive approach/neuroscience?
    • Real-life application - AI
    • Credibility - uses experimental methods
  • What are the weaknesses of the cognitive approach/neuroscience?
    • Machine reductionism - ignores the influence of human emotion + motivation by comparing to computers (decreases validity)
    • Lacks external validity - too abstract + theoretical through the use of artificial stimuli that may not represent everyday experience
