Verges Psychonomics2008 Verges Psychonomics2008 Presentation Transcript

  • Perceptual Simulation of Verbs and Pictures Michelle Verges Indiana University, South Bend Sean Duffy Rutgers University
  • Research Question: Do object images and motion words direct one’s spatial attention in mental imagery?
    • Interplay between language and perception
    • Representational processes between symbols and referents
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Perceptual Symbol Systems Barsalou (1999, 2008)
    • Sensorimotor representations that simulate perceptual, motor, and introspective processes
    • Integrate constituent features and orientations to form a single, multimodal representation
    • Contrasted with amodal symbol systems
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Perceptual-Interference Effects: Mental imagery can interfere with the direct perception of another stimulus
    • If mental image and physical stimulus overlap spatially (Craver-Lemley & Arteberry, 2001)
    • If mental image and physical stimulus activate different perceptual representations (Estes, Verges, & Barsalou, 2008)
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Spatial Cuing Paradigm
    • Richardson, Spivey, Barsalou, & McRae (2003) horizontal/vertical sentences
    • Bergen, Lindsay, Matlock, & Narayanan (2007) up/down sentences
    • Estes, Verges, & Barsalou (2008) up/down nouns
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions o + cue (ISI) Prior Research Cue
  • Experiment 1 (N = 28) Object Images and Words
    • 32 object images and corresponding labels denoted up or down spatial prime
    • Up: cloud, flag, hat
    • Down: foot, whale, snake
    • Non-spatial: cake, lemon, comb
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Experiment 1 (N = 28) Object Images and Words
    • 32 object images and corresponding labels denoted up or down spatial prime
    • Primes presented centered of computer screen
    • Target letter (X, O) shown at top of bottom of display
    • Picture/word conditions counterbalanced
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Procedure Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions Fixation (250 ms) hat Prime (100 ms) ISI (50 ms) x Target (respond)
  • Results: Object Words Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions Spatial Prime
  • Results: Object Images Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions Spatial Prime
  • Experiment 2 (N = 48) Do perceptual-interference effects occur for motion words?
    • Verbs require holistic representations found in literal sentences (Bergen et al., 2007)
    • But maybe not (Richardson et al., 2003)
    • Verbs serve as the backbone of sentences (Pulverm ü ller, 2005)
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Experiment 2 (N = 48)
    • 32 verbs denoted up or down spatial prime
    • Up: climb, lift, rise
    • Down: dig, dive, fall
    • Non-spatial: choose, draw, tickle
    • Procedure identical to Experiment 1
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Results: Motion Words Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions Spatial Prime
  • Conclusions
    • Object and motion words automatically orient attention to their typical location
    • Interference effects due to sensorimotor representations (Barsalou, 2008; Pulverm ü ller, 2005)
    • Object images do not automatically elicit perceptual simulations in mental imagery
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Implications
    • Spatial representations elicit dual-coding effects in mental imagery (Paivio 1971, 1986, 2007)
    • Developmental processes associated with children’s reading ability
    • Long-term effects of perceptual simulation and mental imagery
    Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
  • Thanks for your attention! Perceptual Simulation Spatial Cuing Experiment 1 Experiment 2 Conclusions
