Unit 3 AP Psychology - Sensation Quiz

The detection and encoding of stimulus energies by the nervous system is called: 1) subliminal perception. 2) signal detection. 3) accommodation. 4) sensation.

4) sensation.

The fact that fear may increase your sensitivity to an almost imperceptible pain stimulus is of most relevance to 1) the Young-Helmholtz theory. 2) place theory. 3) opponent-process theory. 4) frequency theory. 5) signal detection theory.

5) signal detection theory.

Place theory suggests that: 1) the pitch we hear is related to the place where the cochlea's basilar membrane is stimulated. 2) we can locate the place from which a sound is emitted because of the distance between our ears. 3) we have a system for sensing the position and movement of the various parts of our body. 4) structures in the inner ear provide us with a sense of the position of our bodies in space.

1) the pitch we hear is related to the place where the cochlea's basilar membrane is stimulated.

The semicircular canals are most directly relevant to: 1) the vestibular sense. 2) accommodation. 3) hearing. 4) kinesthesis. 5) parallel processing.

1) the vestibular sense.

The process by which our sensory systems convert stimulus energies into neural messages is called: 1) transduction. 2) accommodation. 3) parallel processing. 4) sensory adaptation

1) transduction.

Giulio's bag of marbles is twice as heavy as Jim's. If it takes 5 extra marbles to make Jim's bag feel heavier, it will take 10 extra marbles to make Giulio's bag feel heavier. This best illustrates: 1) the opponent-process theory. 2) Weber's law. 3) sensory adaptation. 4) frequency theory. 5) accommodation.

2) Weber's law.

During a hearing test, many sounds were presented at such a low level of intensity that Mr. Antall could hardly ever detect them. These sounds were below Mr. Antall's: 1) subliminal threshold. 2) absolute threshold. 3) sensory adaptation threshold. 4) difference threshold.

2) absolute threshold.

Sensory adaptation refers to: 1) the process of selecting, organizing, and interpreting sensory information. 2) diminishing sensitivity to an unchanging stimulus. 3) changes in the shape of the lens as it focuses on objects. 4) the process by which stimulus energies are changed into neural impulses.

2) diminishing sensitivity to an unchanging stimulus.

Bottom-up processing involves analysis that begins with the 1) occipital lobe. 2) sensory receptors. 3) optic nerve. 4) cerebral cortex. 5) feature detectors.

2) sensory receptors.

While a student provided directions to a construction worker, two experimenters rudely interrupted by passing between them carrying a door. The student's failure to notice that the construction worker was replaced by a different person during this interruption illustrates: 1) stroboscopic movement. 2) perceptual adaptation. 3) change blindness. 4) visual capture. 5) retinal disparity.

3) change blindness.

Accommodation refers to the: 1) quivering eye movements that enable the retina to detect continuous stimulation. 2) system for sensing the position and movement of muscles, tendons, and joints. 3) process by which the lens changes shape in order to focus images on the retina. 4) diminishing sensitivity to an unchanging stimulus. 5) process by which stimulus energies are changed into neural messages.

3) process by which the lens changes shape in order to focus images on the retina.

While reading a novel, Raoul isn't easily distracted by the sounds of the TV or even by his brothers' loud arguments. This best illustrates: 1) the cocktail party effect. 2) perceptual adaptation. 3) selective attention. 4) subliminal stimulation. 5) transduction.

3) selective attention.

The amount of light entering the eye is regulated by the: 1) retina 2) optic nerve 3) feature detectors 4) iris 5) lens.

4) iris

With her eyes closed, Sierra can accurately touch her mouth, nose, and chin with her index finger. Sierra's accuracy illustrates the importance of 1) accommodation. 2) sensory interaction. 3) sensory adaptation. 4) kinesthesis. 5) feature detectors.

4) kinesthesis.

Which of the following would play a role in quickly alerting you to a gas leak in your home? 1) feature detectors 2) vestibular sacs 3) cerebellum 4) olfactory receptors

4) olfactory receptors
