Psychology Chapter on Perception and Distractions

Distractions

• Distractions in the work area can interfere with attention.
• Continuous distractions are consistent, like the sound of a radio. Adjustment to these distractions is quick.
• Discontinuous distractions are irregular, like hearing a voice now and then. They are harder to adjust to and can interfere with work.
• To minimize distractions, focus on your work, ignore distractions, and incorporate them into your work if possible.

Perception

• Perception involves interpreting information from our senses to understand objects, events, and relationships.
• Sense organs and the brain are essential for perception; a lack of functioning in either can affect it.
• Memory images of past experiences help us understand present stimuli.
• Personal interests, acquired interests, needs, desires, beliefs, opinions, and cultural ideals can influence our perception.

Errors in Perception

• Illusions are misinterpretations of real perceptions. For example, mistaking a rope for a snake in the dark.
• Hallucinations are imaginary perceptions not shared by others. For example, an alcoholic seeing "pink elephants."

Causes of Inaccurate Perception

• Defective sense organs: Myopia, deafness, or other sensory issues can cause inaccurate perception.
• Inadequate stimulus: Weak or vague stimuli might be difficult to perceive correctly.
• Too many stimuli at once: It's challenging to accurately perceive one stimulus when multiple stimuli are present.
• Poor health: Illness can impair the functioning of sense organs, leading to inaccurate perceptions.
• Limited attention: Trying to process more than our capacity can result in inaccurate perception.
• Figure merges with the ground: Objects resembling their surroundings are more challenging to perceive, like a white patch on a white wall.
• Lack of guidance: Without knowledge of what to perceive, perception can be inaccurate.

Learning

• Learning involves a relatively permanent change in behavior due to practice.
• It is a process that leads to both positive and negative changes in behavior and involves acquiring, changing, or discontinuing existing behaviors.
• Learning helps individuals adapt and adjust, and is goal-oriented, universal, continuous, and contributes to a balanced personality.

Types of Learning

• Classical conditioning: Association between two stimuli: an unconditioned stimulus (US) and a conditioned stimulus (CS).
• Instrumental conditioning: Association between a response and a stimulus. It allows individuals to adjust behavior based on consequences, including positive and negative reinforcement and punishment.
• Perception learning: Knowledge gained through the five senses: sight, hearing, taste, smell, and touch.
• Verbal learning: Using signs, pictures, symbols, words, figures, sounds, and voices to learn.
• Motor learning: Primarily involving muscle use, like learning to walk, swim, or play instruments.
• Concept learning: Forming mental images representing generalized ideas about things, people, or events.
• Problem-solving: Utilizing cognitive abilities like thinking, reasoning, and imagination to find solutions.
• Attitude learning: Developing favorable or unfavorable responses to objects, people, or situations, influencing how we learn a subject.

Factors Influencing Learning

• General Factors:*
• Maturation: The individual's developmental stage influences their readiness to learn.
• Age: Older children tend to have more patience for learning.
• Nature of learning material: Easy or difficult material influences learning.
• Practice: Practice enhances learning.
• Environment: A stress-free, quiet environment with good ventilation, seating, and lighting is conducive to learning.
• Gender differences: There are no significant gender differences in learning ability.
• Previous experience: Prior knowledge impacts learning.
• Physiological Factors:*
• Sense perception: Weaker senses can limit learning.
• Physical health: Poor health (fever, cold, pain) interferes with learning.

Law of Association

• We learn through associating ideas, leading to one idea triggering another. For example, thinking of thunder automatically brings to mind lightning.

Theories of Learning

• Learning theories focus on environmental influences like associations, reinforcements, punishments, and observations.
• Trial and Error Theory (Edward Thorndike): Learning occurs through trying different strategies, with incorrect responses decreasing over time.
• Learning by Conditioning (Ivan Pavlov ): This theory involves associating a neutral stimulus with an unconditioned stimulus to create a conditioned response.
• Theory of Operant Conditioning (B.F. Skinner): Learning occurs through consequences of actions. Positive consequences reinforce behaviors, while negative consequences deter them.
• Theory of Insightful Learning (Wolfgang Kohler): Learning through sudden understanding, without trial and error, like a "flash of insight."
• Observational Learning (Albert Bandura): Learning by observing and imitating the behavior of others.

Methods of Learning

• Learning by understanding the meaning: Focuses on comprehension rather than rote memorization.
• Spaced vs. Unspaced Learning: Spaced learning involves studying with time intervals, while unspaced learning is massed learning without breaks.
• Part vs. Whole Learning: Part learning involves breaking down material into smaller parts, while whole learning focuses on learning the entire material at once.
