kinesthesis

Which of the following play the biggest role in our feeling dizzy and unbalanced after a thrilling roller coaster ride?

semicircular canals

As you look at an apple, its reflected light travels to the eye. The rods and cones absorb the light and help transmit the information to the brain. This process best illustrates

sensation

Which of the following is the process of detecting environmental stimuli and converting them into signals that can be detected by the nervous system?

the cocktail party phenomenon

Kimmie stood on the sidewalk rather than crossing the street because she saw that the approaching car was quite close to her. Which of the following concepts is best illustrated in this example?

depth perception

Which of the following scenarios is the best example of synesthesia?

Anastasia sees swirls of color when she hears music because stimulation of one sensory pathway leads to the experience of another sensation.

Marlene had an infection that led to deafness in her left ear. Which of the following will be the most likely impact of losing her hearing in her left ear?

She will have trouble locating the source of sounds.

Which of the following anatomical structures is involved in the vestibular sense?

(A) semicircular canals

Which of the following examples best illustrates the concept of interposition?

Because the chair partially obscured his view of the sofa, Brendan perceived the chair as being closer than the sofa.

Dr. Ramen recruited 100 adults to participate in her study. The taste buds of each participant were measured, and the participants tasted a number of foods. She found there was a relationship between the size of a participant's taste buds and the number of foods that a participant could taste. What research method did Dr. Ramen use, and what was she most likely studying?

Correlational; the sensitivity of supertasters

Which of the following best illustrates the most predictable effect of schemas on perception?

Grant has more difficulty recognizing a penguin as a bird than he does a blue jay.

Which of the following scenarios best illustrates the opponent-process theory of color vision?

Kayla sees afterimages of opposing colors when she stares at a poster for a long time.

Which of the following is the best definition for absolute threshold?

The lowest strength of a stimulus that a person can detect 50% of the time

Bryan perceived a duck instead of other animals when viewing an ambiguous image because he watched a documentary about ducks the previous night. Which of the following best explains why Bryan perceived a duck?

Top-down processing, because he constructed the image of the duck piece by piece, starting with his sensory receptors.

A researcher wants to study the human sense of taste over a life span. The researcher has a group of participants taste foods that are salty, bitter, sweet, sour, and umami. Which study would best allow the researcher to test the sensation of taste as people age, and what is the likely outcome?

The researcher follows the same group of people over the course of 40 years. The researcher also measures the number of the people's taste buds throughout the 40 years. The researcher finds that as people grow older, their sense of taste diminishes and their number of taste buds decreases.

iris

change blindness.

The ability to pay attention to only one voice at a time is called

coctail party effect

The coiled, fluid-filled tube in which sound waves trigger nerve impulses is called the

cohela

moncular cues

depth cues, such as interposition and linear perspective, available to either eye alone

The organization of two-dimensional retinal images into three-dimensional perceptions is called

depth preception

Imagine your friend walking toward you in the hall at school. As your friend gets closer, the image cast on your retina

gets larger

conduction hearing loss.

hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea

place theory

in hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated

frequency theory

in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch

parallel processing

The process by which we select, organize, and interpret sensory information in order to recognize meaningful objects and events is called

perception

Helena did not recognize her English teacher when she unexpectedly saw him while traveling in Paris, even though she knew him well back in the classroom. The fact that Helena can recognize her teacher back home more easily than in Paris best demonstrates what concept?

precognition

The light-sensitive inner surface of the eye, containing the rods and cones, is the

retina

rods

gate-control theory

the theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows them to pass on to the brain. The "gate" is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain.
