Sensation & Perception

Question 2

Describe how a pattern is recognised when faced with a sensory stimulus

Answer 2

1. Simulus event is detected and stored in the sensory register(memory)
2. An analysis component extracts the information from register
3. A comparison component compares the extracted data and known patterns stored in LTM
4. A decision component decides which is the best match

Question 3

Types of processing for pattern recognition

Answer 3

Bottom-up processing: info flows from sensory store to LTM

Top-down processing: info flows from LTM to sensory store

Question 4

Capacity and duration of sensory store

Answer 4

Large, 0.25-0.3s

Question 5

Theories for object recognition

Answer 5

Template theory
Feature theory
Structural theory
