Perception Quiz

Sensation is to _ as Perception is to _

• Raw stimulus, representation of the stimulus

• Perception, interpretation of emotions

• Reflex, cognitive processes

• Detection, subjective experience

What is transduction?

• The transformation of neural impulses into motor actions

• The interpretation of sensory information by the brain

• The conversion of physical signs to neural signs sent to the CNS

• The amplification of physical stimuli in the sensory organs

How is Perception measured?

• The absolute threshold and the Just noticeable difference.

• Sensory intensity and signal clarity

• Neural transmission rates and processing speed

• Adaptation levels and contextual cues

The Absolute threshold is to _ as the Just Noticeable Difference is to _ for detection

• Signal clarity, sensory saturation

• Maximum detection level, average difference

• Minimal intensity needed, minimal change needed

• Baseline intensity, heightened perception

What field of psychology measures the relationship between physical characteristics and the observer’s perception?

• Neuropsychology

• Psychophysics

• Behavioral Psychology

• Cognitive Neuroscience

Noah has annoying, noisy roommates. Today, Noah has decided to try his best to study even if his roommates won’t shut up. Noah eventually stops registering any noise and is able to focus, this is due to:

• Selective attention

• Cognitive dissonance

• Annoyance masking

• Sensory adaptation

For the Signal detection theory, sensibility is to _ as decision criterion is to _

• Signal intensity, the observer's reaction speed

• The capacity to detect a stimulus, the internal barrier to acknowledge a stimulus.

• Neural processing, conscious awareness

• Stimulus clarity, environmental interference

According to the signal detection theory; Whether you detect a stimulus or not, it depends on:

• Decision criterion and Sensibility

• Stimulus duration and location

• Neural capacity and sensory accuracy

• Signal intensity and brain processing speed

“For every sense domain, the change in a stimulus that is just noticeable is a constant proportion despite variation of intensities”

• Fechner’s Principle

• Signal Detection Theory

• Weber’s Law

• Threshold Law

Who created Weber’s Law?

• Ernst Weber

• Hermann von Helmholtz

• Wilhelm Wundt

• Gustav Fechner
