Explain the important human characteristics.

Important human characteristics are :

1. Perception:
   • Definition: It’s how we understand and become aware of our surroundings using our senses like sight, sound, and smell.
   • Key points:
     • Proximity: Things close to each other seem connected.
     • Similarity: Similar traits make us see things as related.
     • Matching patterns: Same shapes have the same meaning.
     • Succinctness: Simple shapes are easier to remember.
     • Closure: Our brain completes incomplete shapes.
     • Unity: Closed shapes are seen as a group.
     • Continuity: Lines can be mentally extended.
2. Memory:
   • Definition: Our ability to recall information.
   • Components:
     • Short-term memory: Processes information for a short time.
     • Long-term memory: Stores our knowledge.
   • Key points:
     • Short-term memory processes one thing at a time.
     • Information in short-term memory lasts 10-30 seconds.
     • Long-term memory is where our knowledge is stored.
     • Learning involves transferring info from short-term to long-term.
     • Repetition helps in learning.
3. Sensory Storage:
   • Definition: The automatic processing of information collected from our senses.
   • Key points:
     • Unconscious and constantly replaced by new information.
     • Acts like radar, scanning the environment for important things.
4. Visual Acuity:
   • Definition: The eye’s ability to see details.
   • Key points:
     • Objects become clearer as we look at them and less clear when we look away.
     • Optimum visual acuity on a screen is in a small area.
5. Foveal and Peripheral Vision:
   • Definition: Foveal focuses directly on something, while peripheral senses surroundings.
   • Key points:
     • Cooperative: Peripheral vision can guide the eye in a visual search.
     • Competitive: It can distract and compete with foveal vision for attention.
