Question 1

Békésy

Answer 1

Empirical studies led to traveling wave theory of pitch perception which, at least partially, supported Helmholtz’s place-resonance theory

Question 2

Berkeley

Answer 2

Developed a list of depth cues that help us to perceive depth

Question 3

Broadbent

Answer 3

Proposed filter theory of attention (selective attention = all or nothing)

Question 4
