Variations in Psychological Attributes, Self, and Personality

Psychological Attributes and Individual Differences

• Individual Differences: Variations among individuals regarding single or multiple characteristics, distinguishing one person from another (Carter B. Good, 1959; Anne Anastasi, 1965).

• Main Domains of Attributes:

  • Intelligence: Global capacity to understand the world, think rationally, and use available resources effectively when faced with challenges.

  • Aptitude: Underlying potential for acquiring specific skills if given proper environment and training.

  • Interest: Individual preference for engaging in one or more specific activities relative to others.

  • Personality: Relatively enduring characteristics of a person that make her or him distinct from others.

  • Values: Enduring beliefs about an ideal mode of behaviour.

Assessment Methods

• Psychological Test: 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: In-depth study of an individual in terms of her/his psychological attributes and history in the context of their psychological environment.

• Observation: Employing systematic, organized, and objective procedures to record behavioural phenomena occurring naturally.

• Self-Report: Method in which a person provides factual information about herself/himself and/or beliefs.

Theories of Intelligence

• Definitions of Intelligence:

  • David Wechsler (1944): Aggregate or global capacity of an individual to act purposefully, to think rationally, and to deal effectively with his environment.

  • Howard Gardner (1986): Ability or skill to solve problems or fashion products which are valued within one or more cultural settings.

  • Oxford Dictionary: Power of perceiving, learning, understanding, and knowing.

• Spearman’s Two-Factor Theory (1927):

  • General Factor ($g$): General mental ability involved in almost all intellectual activities.

  • Specific Factor ($s$): Specific abilities required for particular tasks.

  • Total Ability Formula: $g + s_1 + s_2 + s_3 + s_4 + \frac{}{}\text{...} = A$

• Gardner’s Theory of Multiple Intelligences: Eight distinct intelligences: Linguistic, Logical-mathematical, Spatial, Musical, Bodily-kinaesthetic, Interpersonal, Intrapersonal, and Naturalistic.

• Sternberg’s Triarchic Theory (1985):

  • Componential (Analytical): Analysis of information to solve problems (includes knowledge acquisition, meta/higher-order, and performance components).

  • Experiential (Creative): Using past experiences creatively to solve novel problems.

  • Contextual (Practical): Dealing with daily environmental demands ("street smartness" or "business sense").

• PASS Model of Intelligence (J.P. Das, Jack Naglieri, Kirby, 1994):

  • Functional Units: Arousal/Attention, Simultaneous and Successive Processing, and Planning.

  • Assessment Tool: Cognitive Assessment System (CAS) for individuals between $5$ and $18$ years of age.

Assessment & Variations of Intelligence

• Concept of MA & IQ:

  • Alfred Binet & Theodore Simon (1905, 1908): Concept of Mental Age ($MA$). Retardation defined as being $2$ mental age years below Chronological Age ($CA$).

  • William Stern (1912): Devised Intelligence Quotient ($IQ$):     $IQ = \frac{MA}{CA} \times 100$

• Population Distribution of IQ: Bell-shaped normal curve symmetrical around mean $IQ = 100$.

  • Above 130: Very superior ($2.2$

  • 120–130: Superior ($6.7$

  • 110–119: High average ($16.1$

  • 90–109: Average ($50.0$

  • Below 70: Intellectually disabled ($2.2$

• Highest IQ Figures: Young -Hoon Kim ($276$), Terence Tao ($228$), Leonardo da Vinci ($180-220$), Albert Einstein ($160$ and $190$), Isaac Newton ($190$ and $200$).

• Intellectual Disability (AAMD Definition): Manifested between ages $0$ and $18$ with sub-average intellectual functioning ($IQ < 70$) and adaptive deficits.

  • Mild: $IQ$ $55$ to approximately $70$

  • Moderate: $IQ$ $35-40$ to approximately $50-55$

  • Severe: $IQ$ $20-25$ to approximately $35-40$

  • Profound: $IQ < 20-25$

• Intellectual Giftedness: Lewis Terman (1925) studied $1500$ children with $IQ \text{ of } 130$ and above. Involves a combination of high ability, high creativity, and high commitment.

• Types of Intelligence Tests:

  • Individual vs. Group tests; Verbal, Non-Verbal (e.g., Raven’s Progressive Matrices), or Performance tests.

  • Key Scales: WAIS (ages $16-90$, fifth edition WAIS-5), WISC (ages $6-16$), WPPSI (ages $2\text{ years } 6\text{ months}$ to $7\text{ years } 7\text{ months}$), Stanford-Binet.

• Testing in India: S.M. Mohsin (pioneered Hindi test in 1930s), C.H. Rice (standardized Binet in Urdu/Punjabi), Mahalanobis (Bengali). Catalogued by NLEPT at NCERT. Long and Mehta documented $103$ tests. Indian tests include Bhatia’s Battery, Pramila Pathak’s Draw-a-Man Test, R. Ramalingaswamy’s WAIS adaptation, and Malin’s Intelligence Scale.

• Cultural Perspectives: Western technological intelligence focuses on speed, analysis, and achievement. Indian tradition focuses on integral intelligence (Buddhi), emphasizing cognitive, social, emotional, and entrepreneurial competencies (J.P. Das).

Emotional Intelligence, Aptitude, and Creativity

• Emotional Intelligence: Introduced by Salovey and Mayer; processing emotional information accurately and efficiently ($EQ$).

• Aptitude: Specific capacity or potential to acquire skills with training (Bingham, 1937; Traxler, 1957).

  • Independent Tests: Clerical, Mechanical, Numerical, Typing Aptitude.

  • Multiple Test Batteries: Differential Aptitude Tests (DAT, Indian adaptation by J.M. Ojha with $8$ subtests), GATB, ASVAB.

• Creativity: Ability to produce something new and unique; relies primarily on divergent thinking.

  • Indian Creativity Tests: Baqer Mehdi’s tests, Sharma’s divergent production ability test, Saxen’s tests.

Concept of Self

• Definitions:

  • Carl Rogers: Organized, consistent set of perceptions and beliefs about oneself (self-concept vs. ideal self).

  • Defence Mechanisms: Unconscious anxiety-reduction tools — Repression, Projection, Denial, Reaction Formation, Rationalisation.

  • Psychosexual Development: Five stages — Oral, Anal, Phallic (Oedipus/Electra complexes), Latency, Genital. Unresolved issues cause Fixation or Regression.

• Post-Freudian / Neo-Analytic Theorists:

  • Carl Jung: Analytical Psychology; Collective unconscious composed of archetypes.

Behavioural, Cultural, & Humanistic Approaches

• Behavioural Approach: Personality as learned response patterns to environmental stimuli and reinforcement (Pavlov, Skinner, Bandura).

• Cultural Approach: Personality as an adaptation to ecological/economic demands (e.g., Birhor tribe of Jharkhand encouraging autonomy vs. agricultural societies encouraging obedience).

• Humanistic Approach:

  • Carl Rogers: Fully functioning person striving for self-actualisation; congruence between real self and ideal self fostered by unconditional positive regard.

  • Abraham Maslow: Self-actualisation reached through the hierarchy of human needs.
