Key Topics to Revise

1

Sensory Processes

  • We have seven sense organs: five external (eyes, ears, nose, tongue, skin) and two internal (kinesthetic and vestibular systems)
  • Each sense organ detects specific types of stimuli and converts them into neural impulses
  • Sensation is the immediate basic experience of stimulus attributes like 'hard', 'warm', 'loud', 'blue'
2

Attention

  • Attention is the process of selecting certain stimuli from many available options
  • Has four main properties: selection, alertness, concentration, and search
  • Attention has focus (center of awareness) and fringe (vague awareness)
3

Theories of Selective Attention

  • Filter Theory (Broadbent): Stimuli create bottleneck, selective filter allows only one through
  • Filter-Attenuation Theory (Triesman): Filter weakens rather than blocks unselected stimuli
  • Multimode Theory (Johnston & Heinz): Selection possible at three stages with varying mental effort
4

Perception

  • Perception is the process of recognizing, interpreting, and giving meaning to sensory information
  • Involves construction of reality from individual's perspective
  • Bottom-up processing: recognition starts from parts to whole
