5 Matching Questions

  1. image generation
  2. perceptual reference frame
  3. intramodal interference
  4. Indeterminacy
  5. serial processing
  1. a (Kosslyn, Reiser, Farah, Fliegel, 1983)

    -a. Takes longer to construct more detailed images, or those described as having more parts, e.g., "two overlapping rectangles" vs. "five squares in form of a cross"

    Or,
    -----Four columns of dots, 3 per column, vs. Three rows of dots, 4 per row


    -b. The smaller the image size (or smaller the part/detail asked about), the longer the RT

    --does a rabbit have ears, vs.does a rabbit have whiskers? (more obvious in our image generation that a rabbit has ears)

    (also structural equivalence)
  2. b ??
  3. c (part of spatial equivalence)

    -Kosslyn: image & perception share a "visual buffer"
    a. Brooks (1968)
    --Visual/Verbal Task x Visual/Verbal Response

    RT (in sec) as a function of Task x Response Mode
    *table shown with this info*
    *(also implicit encoding of spatial information)*
  4. d -The steps in the processing of sensory information that operate sequentially, an item at a time, on the available sensory information.
  5. e -Images leave out significant details, and cannot be re-analyzed for those details the way that pictures can.
    *E.g., image of a tiger does not specify an exact number of stripes

5 Multiple Choice Questions

  1. **key idea: images can be scanned, in much the same way as physical percepts can be
    - imaginal scanning is functionally equivalent to peceptual scanning

    -Kosslyn's experiment: participants were shown a map of an imaginary island, participants studied until they can reproduce it accurately from memory
    -instructed that on hearing name of an object on the island, they should picture the map, mentally scan directly to the mentioned object, and finally press a key as soon as they arrived at the location of the named object
    • Results: almost perfect linear relationship between the distances separating successive pairs of objects in the mental map and the amount of time it took participants to press the button
    • -in other words, participants seem to have encoded the map in the form of an image
  2. -the structure of Images is like that of actual perceived objects, and can be re-organized & re-interpreted.

    -Images are analogous to 2-1/2 D sketches.
    --Images are assembled; assembly based on description (and interpretation) of component parts
    --more complex images take longer to generate
  3. -imaging is like seeing (with a "mind's eye"); the same 'visual screen' is used
    1. Perky's (1910) tomato/leaf/banana experiment

    2. Farah (1985), like Perky (1910), found that Ss found it easier to perceive a low-contrast letter (an H or a T) if they had been imaging that letter.
  4. States that imagery is like perception, in that images retain some of the sensory qualities of perception.

    -There is a more or less direct relationship between representation and referent.
    -Spatial relationships are also directly captured.
    -Relations represented implicitly.
    -Different kind of representation for each sense.
  5. -spatial relations can be implicitly represented in a picture/ image (without explicit attention ever having been paid to the spatial relations).

5 True/False Questions

  1. transformational equivalencedon't know 2.

          

  2. functional equivalencedon't know 2.

          

  3. mental imagery-A task in which participants are presented with a rotated figure and must discern whether the figure is normal or, say, mirror-reversed. Participants apparently must visualize the figure rotated to an upright position before responding.
    -The response time is linear with how many degrees the subject has to mentally rotate the pictures (i.e., the less necessary the rotation, the quicker the response time)
    - (Shephard)

          

  4. propositions-A task in which participants are presented with a rotated figure and must discern whether the figure is normal or, say, mirror-reversed. Participants apparently must visualize the figure rotated to an upright position before responding.
    -The response time is linear with how many degrees the subject has to mentally rotate the pictures (i.e., the less necessary the rotation, the quicker the response time)
    - (Shephard)

          

  5. neurological equivalence-imaging is like seeing (with a "mind's eye"); the same 'visual screen' is used
    1. Perky's (1910) tomato/leaf/banana experiment

    2. Farah (1985), like Perky (1910), found that Ss found it easier to perceive a low-contrast letter (an H or a T) if they had been imaging that letter.
