To represent the world, we must detect physical energy (stimulus) from the environment and convert it into neural signals, a process called ______.

• absolute threshold

• sensation
• perception
• difference threshold

When we select, organize, and interpret our sensations, the process is called ________.

• interpretation
• sensation
• perception
• observation

______________ begins with the senses, such as vision, hearing, smell, touch, and taste, which receive and relay external stimuli.

• Bottom Up Processing

• Top Down Processing

Which definition best matches ABSOLUTE THRESHOLD?

• The threshold at which a stimulus becomes painful.
• The minimum intensity of a stimulus that can be detected.
• The average intensity of a stimulus that is perceived.
• The maximum intensity of a stimulus that can be ignored.

what are factors that may lead to someone's absolute threshold changing over time?

• Age

• Health

• Environmental Changes

• All of the above

What is difference threshold?

• The difference threshold is the minimum detectable difference in stimulus intensity.
• The difference threshold is the total amount of stimulus intensity present.
• The difference threshold is the maximum detectable difference in stimulus intensity.
• The difference threshold refers to the average intensity of a stimulus.
