Study Notes
Unit 2: Psychology for Physiotherapists
- Main focus: Sensation and Perception
Sensation
- Sense organs act as transducers, converting environmental energy into neural impulses
- Basic sensations: touch, taste, smell, hearing, and sight
- Excludes: hunger, thirst, fatigue, and pain
Attention
- Involuntary attention: no conscious effort required, e.g., loud sounds, bright colors, sharp pain
- Factors influencing attention: intensity, size, movement, novelty, and sudden change
- Selective attention: focusing on specific stimuli while ignoring others
- Capacity of attention: limited, maximum amount of material that can be attended to in one period
Perception
- Definition (R.E.Silverman): the process of interpreting and making sense of sensations
- Involves: sensation and interpretation
- Incorrect perception: illusion (false interpretation of stimuli)
Perceptual Disorders
- Agnosia: inability to identify objects through one or more senses, despite normal senses and memory
- Astereognosis: inability to recognize objects by touch
