    Study Notes

    Defining Intelligence

    • Intelligence is a hypothetical construct, often linked to higher-level abstract thought processes.
    • People who excel in abstract reasoning, problem-solving, and decision-making are generally considered more intelligent than those who struggle with these mental activities.
    • Intelligence influences our learning, planning, problem-solving, decision-making abilities, and overall capacity to navigate everyday life.
    • Intelligence is not directly observable but is assessed through tests designed to measure it.
    • While no single definition of intelligence is universally agreed upon, a commonly accepted definition describes it as the ability to learn from experiences, acquire knowledge, and utilize resources effectively for adapting to new situations or solving problems.
    • Psychologists now believe the definition of intelligence should include skills valued by the culture in which a person lives, as these skills are essential for navigating and surviving within that culture.
    • Western cultures often prioritize skills like performance, speed, and achievement motivation, while Indian culture emphasizes self-reflection and interpersonal connections.

    Intelligence Quotient (IQ)

    • IQ scores are a measure of intelligence, calculated by dividing mental age by chronological age, then multiplying by 100.
    • When mental age exceeds chronological age, the IQ score is above 100.
    • When chronological age exceeds mental age, the IQ score is below 100.
    • Modern intelligence tests use deviation IQ instead of ratio IQ. Deviation IQ statistically measures a person's score relative to their age group, indicating how far above or below average their score is.

    Distribution of IQ Scores

    • The distribution of IQ scores within a population tends to follow a normal distribution, often referred to as a bell curve.
    • The majority of individuals have IQ scores within the middle range of the distribution, with fewer people having extremely high or low scores.
    • The average IQ score in the population is 100.
    • Individuals with IQ scores between 90 and 110 are considered to have normal intelligence.

    The Influence of Heredity and Environment

    • Studies have shown that adopted children's IQ scores are more closely correlated with their biological parents' IQs than their adoptive parents' IQs.
    • Long-term studies have revealed that the correlation between adopted children's intelligence and their biological parents increases over time, while the correlation with their adoptive parents decreases.
    • These findings suggest that heredity plays a significant role in human intelligence.
    • The concept of heritability of intelligence measures the proportion of intelligence variance within a population attributable to genetic factors. Heritability estimates range from 35% in childhood to 75% in adulthood, with an estimated average heritability of 50%.
    • The increase in heritability with age could be partly explained by the fact that individuals gain more control over their environment as they grow older, reducing the impact of environment on their intelligence.
    • While heredity is influential, environmental factors also play a crucial role in shaping intelligence.
    • Twin studies show that identical twins raised in different environments have less similar IQs than identical twins raised in the same environment, suggesting that environmental influences impact intelligence.
    • Adoption studies similarly indicate a role for environment, as individuals adopted into different families exhibit varying IQ scores, even though they share the same biological parents.

    Theories of Intelligence

    • Gardner’s Theory of Multiple Intelligences: Proposes eight distinct intelligences:
      • Linguistic: skills in language and communication.
      • Logical-mathematical: skills in reasoning, problem-solving, and abstract thinking.
      • Spatial: skills in visualizing and manipulating objects in space.
      • Musical: skills in tasks involving musical rhythms and patterns.
      • Bodily-kinesthetic: skills for using the body flexibly and creatively.
      • Interpersonal: skills in interacting and understanding people, being sensitive to their emotions.
      • Intrapersonal: skills involved in self-understanding.
      • Naturalistic: skills in being sensitive to the features of the natural world.
      • Existential: skills concerning the broader meaning of life.
    • Planning, Attention-Arousal, Simultaneous and Successive (PASS) Model: Developed by J.P. Das, J.A. Naglieri, and J.R. Kirby, this model proposes three functional units of the brain:
      • Attention-Arousal: Related to the brain stem and lower cerebral cortex, this unit involves the ability to selectively attend to stimuli while ignoring distractions.
      • Simultaneous Processing: Associated with the parietal and occipital lobes, this unit involves integrating separate concepts into a cohesive whole.
      • Successive Processing: Linked to the frontal and temporal lobes, this unit enables remembering and integrating information in sequential order.
      • Planning: Associated with the prefrontal lobes, this unit is responsible for planning, self-monitoring, and structuring cognitive abilities.

    Emotional Intelligence

    • Definition: Emotional intelligence refers to the ability to perceive, understand, manage, and utilize emotions effectively.
    • Components: Key components of emotional intelligence include self-awareness, self-regulation, motivation, empathy, and social skills.
    • Importance: Emotional intelligence is crucial for building strong relationships, managing stress, resolving conflicts, and achieving personal and professional success.
    • Measurement: Emotional intelligence can be measured through various tests like the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT).
