Study Notes
Perception, Attention and Memory: Perception
- Perception is more complex than reality, exceeding the projected image (e.g., image of a cube).
- Sensation: the initial, direct contact with reality; the pure and immediate capture of a sensory object through the senses, without any construction.
- Perception: a process where the brain selects, organizes, and assigns meaning/sense to received information. It transforms the sensations caused by a stimulus into a mental representation of an object with meaning—a constructive process.
- Cognition: a process that involves manipulating perceptions.
Sensory Systems Characteristics
- Specific sensory organs, specific receptors, and specific cortices are specialized.
- They function with activation/response thresholds:
- Absolute threshold: minimum stimulus intensity for sensation.
- Differential threshold: minimum difference needed in two stimuli's intensity for a person to perceive them as different.
- Input from sensory organs: environmental energy.
- Output from sensory organs: nervous impulses.
- Sensory systems vary among species.
- Habituation: adaptation to stimuli.
