Psychology 101: Attention and Perception

Attention

• Definition: A process where an individual selects specific stimuli based on their interests and attitudes from a variety of stimuli in their environment.
• Types: Voluntary (volitional) and Involuntary (non-volitional).
• Voluntary Attention: Requires conscious effort, for example, solving a math problem or answering an exam question.
• Involuntary Attention: Aroused without conscious effort, for example, reacting to loud sounds, bright lights, or strong odors.

Distraction

• Definition: Any stimulus which interferes with attention or diverts focus from the desired object of attention.
• Sources: External factors (noise, music, lighting, seating, temperature, ventilation, teaching methods, teacher’s voice) and Internal factors (emotional disturbances, ill health, boredom, lack of motivation, fatigue).

Perception

• Inaccurate Perception: Misinterpretation of a stimulus leading to an illusion. For example, a rope appearing as a snake in the dark.
• Hallucination: Imaginary perceptions experienced by an individual, not shared by others. For example, an alcoholic seeing 'pink elephants.' More common in mentally ill individuals.
• Causes for Inaccurate Perception:
  • Defective functioning of sense organs (myopia, deafness, anesthesia).
  • Inadequate stimulus (weak light, soft sound).
  • Too many stimuli at one time.
  • Poor health.
  • Limited attention.
  • Figure merges in the ground (difficulty perceiving an object resembling its surroundings).
  • Lack of guidance on what to perceive. The nurse learns to perceive signs of illness or wellness by understanding those signs.

Learning

• Definition: A relatively lasting change in behavior due to practice (Hilgard & Atkinson).
• Nature:
  • A continuous process.
  • Leads to behavioral changes, both positive and negative.
  • Involves acquiring, changing, or discontinuing behaviors.
  • Facilitates adjustment and adaptation.
  • Purposeful and goal-oriented.
  • Universal and ongoing.
  • Contributes to a balanced development of personality.

Types of Learning

• Classical Conditioning: Association between two stimuli: unconditioned stimulus (US) and conditioned stimulus (CS).
• Instrumental Conditioning: Association between a response and a stimulus, allowing an organism to adapt behavior based on consequences (positive or negative reinforcement, punishment).
• Perception Learning: Knowledge gained through sensory perception (sight, hearing, taste, smell, touch).
• Verbal Learning: Acquisition of knowledge through signs, symbols, words, figures, sounds, or voices.
• Motor Learning: Involves primarily the use of muscles, such as learning to walk, swim, play ball, or play the piano.
• Concept Learning: Forming a generalized mental image of things, persons, or events.
• Problem Solving: Higher-order learning requiring cognitive abilities like thinking, reasoning, observation, imagination, and generalization.
• Attitude Learning: Learning based on favorable or unfavorable responses to objects, persons, or situations, influenced by attitudes.

Factors Influencing Learning

• General Factors:
  • Maturation (readiness to learn).
  • Age (patience with learning).
  • Nature of learning material (difficulty).
  • Practice.
  • Environment (stress-free, quiet, well-ventilated, comfortable seating, good lighting).
  • Gender (no difference in learning ability).
  • Previous experience.
• Physiological Factors:
  • Sense perception (weak perception affects learning).
  • Physical health (illness affects perception).

Laws of Learning

• Law of Association: Ideas are linked through association, explaining the flow of thoughts. For example, thinking of thunder automatically leads to thinking of lightning.

Theories of Learning

• Environmental influences: Associations, reinforcements, punishments, and observations.
• Main Theories:
  • Trial and Error Theory of Learning: (Edward Thorndike) - Learning by trial and error, selecting the correct response from multiple possibilities.
  • Learning by Conditioning: (Ivan Pavlov) - Association between a neutral stimulus and a natural stimulus, creating a learned response.
  • Theory of Operant Conditioning: (B.F. Skinner) - Learning occurs through natural consequences of actions. Reinforcement strengthens behavior, while punishment weakens it.
  • Theory of Insightful Learning: (Wolfgang Köhler) - Sudden understanding of a solution without trial and error.
  • Observational Learning: (Albert Bandura) - Learning through observing a model's behavior: paying attention, remembering, reproducing, and being motivated to perform the behavior.

Methods of Learning

• Learning by Understanding the Meaning: Comprehending the material.
• Space Vs Unspaced Learning:
  • Unspaced (Massed) Learning: Learning without intervals.
  • Spaced Learning: Learning with intervals between sessions.
• Part Vs. Whole Learning:
  • Part Learning: Learning in parts.
  • Whole Learning: Learning the entire material at once.
