Tip

  • Group icons by area to remember them more effectively.
  • Focus on distinctive shapes first rather than memorizing everything at once.

Visual working memory is limited to about 3-4 items. Kim's Game directly measures this capacity limit and is a core paradigm in change detection research.

  • Luck & Vogel (1997) - Capacity of visual working memory for features and conjunctions
