Chapter 1: Variations in Psychological Attributes

Introduction

• People differ in how they perceive, learn, and think, as well as in their performance on various tasks.  
• These differences are called individual differences.  
• The study of individual differences has been a major concern of modern psychology since the time of Galton.  

Individual Differences in Human Functioning

• Individual variations are common within and across all species.  
• People vary in terms of physical characteristics (height, weight, etc.) and psychological dimensions (intelligence, personality, etc.).  
• Individual differences refer to the distinctiveness and variations among people’s characteristics and behaviour patterns.  
• Some psychologists believe that our behaviours are influenced by our personality traits, while others believe that situational factors play a larger role.  
• Situationism is the view that situations and circumstances influence our behaviour more than personality traits.  

Assessment of Psychological Attributes

• Psychological attributes are involved in various phenomena, from simple reaction times to complex emotions like happiness.  
• Assessment is the measurement of psychological attributes and their evaluation, often using multiple methods in terms of certain standards of comparison.  
• Formal assessment is objective, standardized, and organized, while informal assessment is subjective and varies from case to case.  
• Some important domains of psychological attributes include:
  • Intelligence: The global capacity to understand the world, think rationally, and use resources effectively.  
  • Aptitude: The underlying potential for acquiring skills.  
  • Interest: An individual’s preference for engaging in one or more specific activities.  
  • Personality: Relatively enduring characteristics that make a person distinct from others.  
  • Values: Enduring beliefs about an ideal mode of behaviour.  

Assessment Methods

• Psychological Test: An objective and standardized measure of an individual’s mental and/or behavioural characteristics.  
• Interview: Seeking information from a person on a one-to-one basis.  
• Case Study: An in-depth study of an individual in terms of their psychological attributes and history. 
• Observation: Employing systematic procedures to record behaviour occurring naturally in real-time. 
• Self-Report: A method in which a person provides factual information about themselves and/or their opinions and beliefs.  

Intelligence

• Intelligence is a key construct used to understand how individuals differ from one another.  
• Early intelligence theorists defined intelligence as the power of perceiving, learning, understanding, and knowing.  
• Alfred Binet defined intelligence as the ability to judge well, understand well, and reason well.  
• David Wechsler defined intelligence as the global and aggregate capacity to think rationally, act purposefully, and deal effectively with the environment.  
• Gardner and Sternberg suggested that an intelligent individual not only adapts to the environment but also actively modifies or shapes it.  

Theories of Intelligence

• Psychometric/structural approach: Considers intelligence as an aggregate of abilities and expresses performance in terms of a single index.  
• Information-processing approach: Describes the processes people use in intellectual reasoning and problem-solving.  

Specific Theories:

• Binet’s Uni-factor Theory: Intelligence is a single, similar set of abilities used to solve any problem.  
• Spearman’s Two-factor Theory: Intelligence consists of a general factor (g-factor) and specific factors (s-factors).  
• Thurstone’s Theory of Primary Mental Abilities: Intelligence consists of seven primary abilities: verbal comprehension, numerical abilities, spatial relations, perceptual speed, word fluency, memory, and inductive reasoning.  
• Jensen’s Hierarchical Model: Intelligence consists of abilities operating at two levels: Level I (associative learning) and Level II (cognitive competence).  
• Guilford’s Structure-of-Intellect Model: Classifies intellectual traits among three dimensions: operations, contents, and products.  
• Gardner’s Theory of Multiple Intelligences: There are eight distinct types of intelligence: linguistic, logical-mathematical, spatial, musical, bodily-kinaesthetic, interpersonal, intrapersonal, and naturalistic.  
• Sternberg’s Triarchic Theory: There are three basic types of intelligence: componential (analytical), experiential (creative), and contextual (practical).  
• Das, Naglieri, and Kirby’s PASS Model: Intellectual activity involves the interdependent functioning of three neurological systems: arousal/attention, coding/processing (simultaneous and successive), and planning.  

Individual Differences in Intelligence

• Nature vs. Nurture: Intelligence is a product of the complex interaction of heredity (nature) and environment (nurture).  
• Assessment of Intelligence:
  • Mental Age (MA): A measure of intellectual development relative to people of the same age group.  
  • Chronological Age (CA): Biological age from birth.  
  • Intelligence Quotient (IQ): MA divided by CA and multiplied by 100.  
  • Normal Curve: The distribution of IQ scores approximates a bell-shaped curve.  
  • Intellectual Disability: IQ below 70.  
  • Intellectual Giftedness: IQ above 130.  

Variations of Intelligence

• Intellectual Deficiency:
  • Significant sub-average intellectual functioning (IQ below 70) existing concurrently with deficits in adaptive behaviour and manifested during the developmental period (0-18 years).  
  • Levels: mild, moderate, severe, and profound.  
• Intellectual Giftedness:
  • Exceptional general ability shown in superior performance in a wide variety of areas.  
  • Characteristics: advanced logical thinking, high speed in processing information, superior generalization and discrimination ability, advanced level of original and creative thinking, high level of intrinsic motivation and self-esteem, independent and non-conformist thinking, and preference for solitary academic activities.  

Types of Intelligence Tests

• Individual vs. Group Tests: Individual tests are administered to one person at a time, while group tests can be administered to several people simultaneously.  
• Verbal vs. Non-Verbal vs. Performance Tests: Verbal tests require verbal responses, non-verbal tests use pictures or illustrations, and performance tests require subjects to manipulate objects.  
• Culture-Fair vs. Culture-Biased Tests: Culture-fair tests do not discriminate against individuals belonging to different cultures, while culture-biased tests may favor one culture over another.  

Culture and Intelligence

• Culture provides a context for intelligence to develop.  
• Vygotsky argued that culture provides a social context in which people live, grow, and understand the world.  
• Different cultures may value different skills and qualities as intelligent.  
• Technological Intelligence: Valued in technologically advanced societies; emphasizes skills of generalization, abstraction, speed, and mental manipulation.  
• Integral Intelligence: Valued in Indian tradition; emphasizes connectivity with the social and world environment, as well as the integration of cognitive and non-cognitive processes.  

Emotional Intelligence

• Emotional Intelligence: A set of skills that underlie accurate appraisal, expression, and regulation of emotions.  
• Emotional Quotient (EQ): Used to express emotional intelligence.  
• Characteristics of Emotionally Intelligent Persons:
  • Perceive and be sensitive to their feelings and emotions.  
  • Perceive and be sensitive to emotions in others.  
  • Relate emotions to thoughts.  
  • Understand the influence of emotions.  
  • Control and regulate emotions.  

Special Abilities

• Aptitude:
  • Refers to special abilities in a particular field of activity.  
  • A combination of characteristics that indicates an individual’s capacity to acquire knowledge or skills after training.  
  • Can be assessed through specialized or multiple aptitude tests.  
• Creativity:
  • The ability to produce ideas, objects, or problem solutions that are novel, appropriate, and useful.  
  • Can be expressed in various forms and levels.  
  • Is influenced by both heredity and environment.

  • Can be assessed through open-ended tests that permit divergent thinking.
