1

What is sensation?

The stimulus detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain

2

What is perception?

The active process of organising the stimulus output and giving it meaning

3

Explain the difference between top-down and bottom-up processing.

Bottom-up processing = a process that consists of recognising and processing information from individual components of a stimulus and constructing a perception of the whole
Top-down processing = prior knowledge, expectations or thoughts act on this information to influence our final perceptual state

4

What are perceptual schemas?

A component of top-down processing – schemas provide mental templates that allow us to identify and classify sensory input, as each of our perceptions is essentially a hypothesis about the meaning of the sensory information

5

What is assimilation?

Incorporating new experiences into existing schema

6

What is accommodation?

The difference made by the process of assimilation

7

Visual perceptual analysis (knowing it is something)

Visual object recognition (describing what the object is)
Semantic system (purpose of object)
