Exam 5: Sensation and Perception

Elena perceives the hills in Leonardo da Vinci's painting as being in the background because they are painted somewhat blurry and with a bluish tint.Leonardo da Vinci made use of the monocular depth cue:

Discuss how psychophysicists can use signal detection procedures to define absolute thresholds for sensory experience and explain why several types of information are required to make an accurate assessment of sensory limits.

The receptive field of a ganglion cell refers to:

The amplitude of sound is measured in decibels.

Outline the key principles of perceptual organization that were described by Gestalt psychologists.

Eleanor placed her left hand in a pan of cold water and her right hand in a pan of hot water for several minutes.She then moved both hands into a pan of lukewarm water.Based on what is known about the perception of temperature, you should predict that the lukewarm water will initially feel:

According to psychologists, bottom-up processing occurs when we use our knowledge, beliefs, and expectations about the world to interpret and organize what we see.

Our increasing sensitivity to light in reduced illumination is due to:

The laws of proximity, similarity, and closure are all examples of the ____________________ principles of organization.

Imagine that the human eye only had cones, and no rods.Based on what is known about the differing functions of the visual receptors, you should predict that under these conditions, people would have:

The small part of the electromagnetic spectrum that is processed by the visual system is:

The physical distance from one cycle of electromagnetic energy to the next determines the:

Based on the relationship between perception and the physical properties of light, you should infer that if the human nervous system were not wired to respond to differences in the wavelengths of reflected light, people would not be able to:

After the neural signals from each visual field separate at the optic chiasm, the majority of the neurons from the optic nerve travel to the:

Modern stringed instruments are tuned to a higher pitch than they were in the 18ᵗʰ century.This means that stringed instruments in the 18ᵗʰ century produced sounds that were of:

The theory of pitch perception that is best able to explain why older people have difficulty hearing high-pitched sounds is known as the:

The gating action proposed in the gate-control theory of pain apparently relies on:

The vestibular sense refers to the ability to sense the position and movement of one's own body parts.

There appear to be four basic tastes: sweet, bitter, ____________________, and sour.

Evidence that some cells in the lateral geniculate nucleus of the thalamus fire with an increased frequency when the eye is stimulated by red light, and fire with a decreased frequency when the eye is stimulated by green light, most directly supports the theory of color vision known as the:
