Invisible Gorilla
Gap, methods, IV/DV
Gap: what about experts?
Method: lung-nodule detection task, gorilla 48x the size, eye tracking
IV: Radiologist (Ex.1) or Naïve (ex.2)
DV: % that did not see gorilla, % that detected nodule
Invisible Gorilla
Results/Conclusions
83% Radiologists look at it
Better at nodules, not gorilla
Even experts struggle
Video game Simon
Known, Gap, Methods
Action video games improves various aspects of visual cognition
Playing reduces simon effect, improve response selection
1 hours a day for 10 sessions then retest with Simon
Video Game Simon
IV, DV
COD: Xbox/Nintendo
Visual: Nintendo
Control
Response times before and after on simon test
Video Game Simon
Results and Conclusions
Faster response times in those trained in shooter game. None in controls/visual training.
Visual/controls: no significant change
Nintendo COD: reduction of simon effect
xbox: reduction of simon effect AND increased speed overall
Conclude: attentional control for response selection and execution among those with ADHD
Mike or me?
Known, Gap
Known: Split brain perform better on facial recognition if it goes to RH
Gap: is RH really specialized for self-recognition?
Mike or me?
Methods
10% increments, faces separately presented to each hemisphere
Mike or me?
Results/Conclusions
Left- self bias
Right- others bias
Double dissociation
Self-memory system that guides behavior in a purposive and meaningful manner
WADA test
Known/Gap
Known: hemisphere specialization: left for language shown by WADA
Gap: normal split brained people?
WADA test methods
anesthetic (sodium amytal) in carotid artery on one side, simulate stroke and shut down one hemisphere
WADA test methods results
Left ANESTHETIZED: see self
Right ANESTHETIZED: see celebrity
Conclusions: unclear if hemisphere bias or memory components, WADA not normal condition
