Gathering and combining discrete bits of (visual) information

 

While cognitive decision-making studies often address how people

combine many different cues, perceptual studies are usually limited to

how people combine just two or three cues. A major benefit of perceptual

psychophysics studies over cognitive decision-making studies is that

behavior could be analyzed much more rigorously. In this talk I will go

over optimal cue-combination and present two experiments that are

perceptual analogs of cognitive decision-making tasks. The first looks

at how people combine seven sequential bits of (visual) information. The

second looks at how people go about sampling costly information to

reduce (visual) uncertainty.
