Exam 4: Sensation and Perception

In research on signal detection theory,incorrectly "detecting" a stimulus that was not presented in a trial is called a:

The physical properties of a stimulus are translated into neural impulses in a process called:

The taste sensation of umami is a result of the detection of _____,which is a naturally occurring substance found in foods such as meat,some cheeses,and mushrooms.

Prolonged exposure to movement in one direction _____ the motion detectors responsive to that direction.When the movement stops,the baseline firing rate of detectors for the opposite direction of motion will be _____ than the firing rate for the detectors that responded to the prolonged movement,leading to motion aftereffects.

An evolutionary view of the perception of human emotions would hold that in societies with strict power hierarchies,people lower in the hierarchy will read the emotions of people higher in status _____ than they will read the emotions of people at their own level.

Where do molecules of photopigment reside?

As part of an experiment,Amanda is seated in front of a blank computer screen.On each trial,a line appears on the screen and then an object appears above the line.The task is to name the object as rapidly as possible.The object is either presented alone or within a scene.For example,a chicken may be presented alone or in a barnyard.People are significantly faster at naming the object when it is presented in the scene.This result is evidence for:

Cognitive factors,including _____,can close the neural gate in the spinal cord that allows the signals of pain to be sent to the brain.

Zheng and Glenn are talking about ways that when a man first meets a woman he can tell if she likes him.Given your knowledge of sensory systems,you could suggest that the man look to see if the woman:
