  1. Apperceptive agnosia
    A form of visual agnosia marked by the inability to recognize simple shakes such as circles and triangles
  2. Associative agnosia
    A form of visual agnosia marked by the inability to recognize complex objects such as an anchor, even though the patient can recognize simple shapes and can copy drawings of complex objects
  3. Bottom-up processing
    The processing of a stimulus in which information from a physical stimulus, rather than from general context, is used to help recognize the stimulus
  4. Categorical perception
    The perception of stimuli being in distinct categories without gradual variations
  5. Feature analysis
    A theory of pattern recognition that claims that we extract primitive features and then recognize their combinations
  6. Fusiform gyrus
    A region in the temporal cortex involved in recognition of complex patterns like faces and words
  7. Fuzzy logical model of perception (FLMP)
    Massaro's theory of perception, which states that stimulus features and context combine independently to determine perception
  8. Geons
    One of Beiderman's 36 primitive categories of sub objects that we combine to perceive larger objects
  9. Gestalt principals of organization
    Principles that determine how a scene is organized into components. The principles include proximity, similarity, good continuation, closure, and good form
  10. Recognition-by-components theory
    Beiderman's theory stating that we recognize objects by first identifying the geons that correspond to the sub objects
  11. Template-matching
    A theory of pattern recognition stating that an object is recognized as a function of its overlap with various pattern templates stored in the brain
  12. Top-down processing
    The processing of a stimulus in which information from the general context is used to help recognize the stimulus.
  13. Word superiority effect
    The superior recognition of letters presented in a word context than when the letters are presented alone
  14. Central bottleneck
    The inability of central cognition to pursue multiple lines of thought simultaneously.
  15. Dichotic listening task
    A task in which participants in an experiment are presented with two messages simultaneously, one to each ear, and are instructed to repeat back the worlds from only one of them
  16. Executive control
    The direction of central cognition, which is carried out mainly by prefrontal regions of the brain
  17. Stroop effect
    A phenomenon in which the tendency to name a word will interfere with the ability to say the color in which the word is printed
  18. Allocentric representation
    A representation of the environment according to a fixed coordinate system
  19. Cognitive maps
    A mental representation of the locations of objects and places in the environment
  20. Egocentric representation
    A representation of the environment as it appears in a current view.
  21. Epiphenomenon
    A secondary mental event that has no functional role in the information processing
  22. Mental imagery
    The processing of perceptual-like information in the absence of external source for the perceptual information
  23. Mental rotation
    The process of perceptual-like information in the absence of an external source for the perceptual information
  24. Default values
    A typical value for slots in a schema representation
  25. Dual-code theory
    Paivio's theory that there are separate visual and verbal representations for knowledge
  26. Embodied cognition
    The viewpoint that the mind can only be understood by taking into account the human body and how it interacts with the environment
  27. Isa link
    A particular link in a semantic network or schema that indicates the superset of the category
  28. Mirror neuron
    A neuron that fires both when the animal is performing the action and when it observed a other animal performing an action
  29. Pv and Hm
    Both had brain damage, both intelligent, hm had normal STM, pv had stm of 2,
  30. Broca aphasia
    Unable to generate speech But can understand
  31. Conductive aphasia
    Difficulty repeating speech
  32. Wernicke's aphasia
    Can generate meaningful but not grammatical speech
  33. Script
    A schema representation proposed by Shank and Ableson for event concepts
  34. Mnemonic technique
    A method for enhancing memory performance by giving the material to be remembered a meaningful interpretation
  35. Node
    An element of propositional or semantic network
  36. Proposition
    The smallest unit of knowledge that can stand as a separate assertion
  37. Propositional network
    A propositional representation in which the relation and arguments of the proposition are linked in a network
  38. Propositional representation
    A representation of meaning as a set of propositions
  39. Schema
    A representation of members of a category based on the type of objects that they are, the parts that they tend to have, and their typical properties. A slot-value structure is used to represent this information
  40. Long term potentiation
    The increase in responsiveness of a neuron as a function of past stimuli
  41. Method of loci
    A mnemonic technique used to associate items to be remembered with locations along a well-known path
  42. Decay theory
    The theory that forgetting is caused by spontaneous decay of memory traces over time
  43. Encoding specificity principle
    Tulving's principle that memory is better when the encoding of an item at study matched the encoding at test
  44. Interference theory
    The theory that forgetting is caused by other memories interfering with the retention of the target memory
  45. Mood congruence
    The phenomenon that's ones memory is better for studied material whose emotional content matches ones mood at test
  46. Power law of forgetting
    The phenomenon that memory performance deteriorates as a power function of the retention interval
  47. State dependent learning
    The phenomenon that memory performance is better when we are tested in the same emotional and physical state as we were in when we learned the material
  48. What is the difference between episodic, semantic, and procedural memory?
    Episodic is dependent on time, place, and what you were doing. Semantic memory is facts. Procedural is motor skills.
