Five questions from the pack.

0 of 5 answered

Q1Fechner's law states that sensation grows with the

B. Fechner's law is S = k log I. A square or exponent describes Stevens' power law forms, and a reciprocal would decrease sensation as intensity rises.

Q2A person stops noticing a perfume after several minutes. Which process is most directly responsible?

D. Constant stimulation reduces olfactory receptor responding, which is adaptation. Lateral inhibition sharpens contrast, and gate control concerns pain.

Q3Finding a red letter among green letters is fast regardless of how many green letters there are. This indicates

B. A target defined by one feature pops out in parallel, so the time does not scale with the number of distractors. Serial search would slow with more items.

Q4Which fiber type carries slow, dull, burning pain?

D. C fibers are unmyelinated and conduct slowly, so they carry dull, burning pain. A-delta fibers are thin and myelinated and carry the fast, sharp component, A-beta fibers carry touch, and motor neurons are efferent.

Q5Reading a smudged letter as an A in CAT but an H in THE is an example of

B. Context supplies expectations that resolve the ambiguity. Bottom-up detection would give the same reading in both cases.

Those are real questions from the pack, word for word.
