-Enunciate each word


-Use training routines


Evidence for Feature Detection - ANSWER✔✔-Feature detectors, detect stimuli, combine for pattern

recognition


Features


key component of pattern recognition - ANSWER✔✔-Color, motion, overall shape


Geons - ANSWER✔✔-Geometrical shapes used in recognition


Gibson's Study


-Letters Varying in Feature Overlap - ANSWER✔✔-Procedure: Shown a pair of letter -> Respond same or

different as quickly as possible (measure reaction time)


Types of Trials:


- E E -> same or different? (same)


- G W -> same or different? (different - low feature overlap)


- P R -> same or different? (different - high feature overlap)


Results: Low feature overlap - quicker than high feature overlap

To land an aircraft, pilots must make accurate judgments of how far they are from


the ground, as well as how fast and from what angle they are approaching the runway.


The bottom-up perceptual cues provided by the environment in this situation


are numerous and overlapping (Gibson, 1979).


Pattern Recognition Study: Letter Search - ANSWER✔✔-(Neiser article)


Procedure: Shown block of letters -> select target letter and respond when found (reaction time)


Trial:


- 1st: feature dissimilar background


- 2nd: feature similar background


Results:


- 1st: Faster


- 2nd: Slower (detect and analyze features)


Feature detectors operating at lower levels


of the visual system detect features of

incoming stimuli such as those shown in


the center of this figure. Later in the


perceptual sequence, bottom-up processing


might recombine these features to aid in


pattern recognition, as in the examples on


the right.


Physiological Data/Evidence of Pattern Recognition: Single Cell Action Potential Recording - ANSWER✔✔-

(Hubel & Wiesel)


Procedure: Presented lines of different orientations and record number of action potentials


Trails: Horizontal lines, Diagonal lines, Vertical lines


Results:


- Horizontal - minimal firing


- Diagonal - more firing


- Vertical - Maximum firing


bottom up processing
