Psych Chapter 6

Studying the impact of boredom and fatigue on people's _____ thresholds would involve research based on signal detection theory.

absolute

is the minimum stimulation needed to detect a particular sensory stimulus (e.g., light, sound, pressure, and taste) 50 percent of the time.

absolute threshold

In terms of vision, _____________ is the ability to adjust to an artificially displaced or inverted visual field.

perceptual adaptation

Drivers sometimes overestimate the distance between their own vehicles and pedestrians who are short, because they rely on the distance cue known as:

relative size

The minute Antonio walks into his mother-in-law's house to visit, he is struck by the strong smell of her perfume. However, after about 10 minutes, he no longer notices the smell. This is probably the result of sensory _____.

adaptation

San Jose police fatally shot a 19-year-old girl who was holding a power drill in 2014. The officer was likely _____ at the time of the encounter.

A neutral facial expression may be perceived as sadder at a funeral than at a party. This best illustrates a(n) _____ effect.

context

The size of the _____ threshold is greater for heavier objects than for lighter ones. This best illustrates Weber's law.

difference

Our tendency to organize stimuli into coherent groups is known as:

grouping

_______occurs when one object partially blocks our view of another, and we perceive the former as closer

interposition

Dr. Kahn studies the relationships between the physical characteristics of stimuli (e.g., intensity) and the psychological experience of them. This field is known as:

psychophysics

Mary-Beth stubbed her toe. All day, she's keenly felt pain in it. She says,"This is so weird! I never think about my toe." This is an example of

sensory adaptation

Two TSA officers are scanning bags at the airport. One of the officers lets a bag go through, but the other officer yells, "Wait, didn't you see that?" Why one officer saw a weapon and the other did not is best explained by:

signal detection theory
