Psychology 1301 Discovering Psychology Chapter 3 Review

Sensation is the process by which:

• We interpret sensory information.

• Sensory receptors detect stimuli.

• We organize sensory information into meaningful patterns.

• We become aware of internal bodily states.

Perception is the process by which:

• Sensory receptors convert stimuli into neural signals.

• We assign meaning to sensory information.

• We detect changes in the environment.

• We respond to sensory input.

Transduction is the process of:

• Organizing sensory information.

• Converting sensory stimuli into neural signals.

• Interpreting sensory experiences.

• Detecting sensory stimuli.

The absolute threshold is:

• The minimum amount of stimulation needed to detect a stimulus.

• The maximum amount of stimulation we can tolerate.

• The point at which we can detect a change in stimulation.

• The level of stimulation that always leads to sensation.

A just noticeable difference (JND) is:

• The smallest difference between two stimuli that can be detected.

• The absolute threshold for a particular stimulus.

• The point at which a stimulus becomes painful.

• The minimum amount of stimulation needed to perceive a stimulus.

Weber's Law states that the JND is:

• A constant amount.

• A constant proportion of the original stimulus.

• Dependent on the intensity of the stimulus.

• Both b and c.

Sensory adaptation refers to:

• The decrease in sensitivity to a constant stimulus.

• The increase in sensitivity to a changing stimulus.

• The ability to detect faint stimuli.

• The process of transduction.

The visible spectrum refers to:

• All electromagnetic radiation.

• The range of wavelengths we can see.

• The range of sound frequencies we can hear.

• The range of odors we can smell.

The cornea's primary function is to:

• Focus light onto the retina.

• Control the amount of light entering the eye.

• Convert light into neural signals.

• Protect the eye.

The lens of the eye:

• Focuses light onto the retina.

• Regulates the size of the pupil.

• Contains the photoreceptor cells.

• Transmits visual information to the brain.
