AP Psych Unit 3 Review

The process of converting incoming physical energy into a neural code that can be processed is called:

• sensory threshold

• transduction

• parallel processing

• transferred excitation

A person is asked to listen to a series of tones presented in pairs, and asked to say whether the tones in each pair are the same or different in pitch. In this situation the experimenter is most likely measuring the individual's

• ability to recognize musical notes

• sound localization ability

• ability to identify different musical instruments
• difference threshold

John walks into art class and is overwhelmed by the smell of paint. However, the longer he stays in the room, the less noticeable the smell becomes. Which of the following appears to be operating in this instance?

• Sensory overload
• Sensory deprivation
• Habituation
• Sensory adaptation

A subliminal stimulus is a stimulus that

• is above the threshold of conscious perception
• is a form of auditory stimulus
• is below the threshold of conscious perception
• can only be perceived by certain individuals

All summer Thomas hears the sound of the icecream truck approaching before his brother Oscar hears it. Thomas most likely has which of the following?

• a slower reaction time
• a hearing impairment
• A greater amount of experience with approaching ice-cream trucks than Oscar

• A lower absolute threshold for hearing than Oscar

An individual’s ability to focus on a particular conversation in a noisy and crowded room is called

• selective attention
• inattentive attention
• sustained attention
• divided attention

Observers watch a group of people passing a basketball back and forth. A researcher asks the observers to count the number of passes made. As they count passes, many of the observers fail to notice a person in a gorilla costume walking through the basketball court. Which of the following is the most likely reason many of the observers do not notice the person in the gorilla costume?

• Visual impairment
• Lack of focus
• Inattentional blindness
• Distraction

Feature detectors are neurons that are turned on or off by specific features of visual stimuli like edges and movement. Where in the visual system are these feature detectors located?

• cerebellum
• retina
• hippocampus
• occipital cortex

In vision, transduction occurs within the

• retina
• optic nerve
• cornea
• left eyeball

Which of the following is the best example of the opponent process theory?

• The more time Stanley spends in the dark, the better he can see in the dark.

• When it gets brighter outside, Tyronne's pupils dilate.

• Fred stares at a green book for a minute, and then when he looks at a white page, he sees the color red.
