Question

what is a perception? *
1 po
o a change in the environment to which an organism responds
o the minimum amount of stimulus necessary for a person to sense it
o the organization of sensory information into meaningful experiences

if a machine is flashing a light that is too weak for a person to see, that light * 1 poin has not reached the
o absolute threshold
o difference threshold

Explanation:

• First question:
• Perception is about organizing sensory information. A change in the environment an organism responds to is more about a stimulus - response. The minimum amount of stimulus to sense is the absolute threshold (related to the second question).
• Second question:
• The absolute threshold is the minimum intensity of a stimulus (like light intensity) that a person can detect. The difference threshold is about detecting a change in a stimulus (e.g., detecting a change in light intensity, not the initial detection of light).

Answer:

• First question: the organization of sensory information into meaningful experiences
• Second question: absolute threshold
