Contemporary Intelligence Models: Gardner, Sternberg, PASS Model & Creativity

1. The Cognitive Shift in Intelligence Research

Classical psychometric theories treated intelligence as a static, numeric trait ($g$). In the late 20th century, cognitive psychology triggered a major paradigm shift: $\textbf{From Psychometrics (What factors compose intelligence?)} \longrightarrow \textbf{Cognitive Processing (How does the mind process information?)}$

Contemporary theories conceptualize intelligence as dynamic, multi-dimensional, information-processing systems embedded within sociocultural contexts.

2. Howard Gardner: Theory of Multiple Intelligences (1983, 1999)

In Frames of Mind (1983), Howard Gardner rejected the monolithic concept of IQ, defining intelligence as: $\text{Intelligence} = \text{A biopsychological potential to process information that can be activated in a cultural setting}$ $\text{to solve problems or create products that are of value in a culture.}$

(9th candidate intelligence proposed in 1999: Existential Intelligence—the capacity to confront ultimate cosmic questions regarding life, death, and human existence).

Gardner’s Eight Scientific Criteria for an Independent Intelligence:

To prevent the arbitrary addition of random skills, Gardner established that any candidate intelligence must meet 8 strict empirical benchmarks:

1. Potential Isolation by Brain Damage: Specific brain lesions impair the intelligence while sparing others (e.g., Broca’s aphasia damages linguistic intelligence but preserves musical and spatial abilities).
2. The Existence of Prodigies and Savants: Exceptional performance in one isolated domain alongside severe intellectual impairment in others (e.g., Savant Syndrome).
3. An Identifiable Core Operation / Information-Processing Mechanism: Each intelligence has unique neural computational subroutines (e.g., pitch detection in musical; syntax parsing in linguistic).
4. A Distinct Developmental History: Unique trajectory of acquisition, peak performance, and decline.
5. Evolutionary Plausibility: Evolutionary survival value in ancestral environments.
6. Support from Experimental Psychological Tasks: Demonstrable autonomy on cognitive interference tests.
7. Support from Psychometric Findings: Modest or low correlation with other domain test batteries.
8. Susceptibility to Encoding in a Culturally Valued Symbol System: Words (linguistic), numbers (logical), musical notation (musical).

3. Robert J. Sternberg: Triarchic Theory of Successful Intelligence (1985, 1999)

Robert Sternberg defined Successful Intelligence as the ability to achieve one’s personal goals in life, within one’s sociocultural context, by capitalizing on strengths and compensating for or correcting weaknesses.

The Triarchic Theory comprises three interactive subtheories:

A. The Componential (Analytical) Subtheory

Deals with the internal mental mechanisms of information processing. Contains three distinct components:

1. Metacomponents (Executive Control): Higher-order processes used to plan, monitor, allocate mental resources, and evaluate problem-solving strategies. (The "executive director" of cognition).
2. Performance Components: Lower-order execution processes that carry out the commands dictated by the metacomponents (e.g., encoding stimuli, retrieving memory representations, executing calculations).
3. Knowledge-Acquisition Components: Processes utilized in learning new information:
   • Selective Encoding: Distinguishing relevant from irrelevant incoming sensory data.
   • Selective Combination: Synthesizing isolated pieces of relevant information into a coherent whole.
   • Selective Comparison: Relating newly acquired information to previously stored knowledge structures in LTM.

B. The Experiential (Creative) Subtheory

Deals with how an individual applies intelligence across varying degrees of task familiarity:

1. Ability to Deal with Novelty: Generating novel, creative responses and synthetic insights when confronted with unique, unprecedented problems.
2. Ability to Automatize Information Processing: Converting newly mastered cognitive sequences into rapid, unconscious, automatic routines (freeing up working memory resources for higher processing).

C. The Contextual (Practical) Subtheory

Deals with the pragmatic application of intelligence to everyday real-world environments ("street smarts" and Tacit Knowledge—action-oriented, unwritten knowledge acquired through personal experience). Involves three behavioral strategies:

1. Adaptation: Modifying one’s own behavior or internal states to fit harmoniously into the current environment.
2. Shaping: Actively transforming, modifying, or changing the external environment when adaptation is unsatisfactory or unacceptable.
3. Selection: Deciding to abandon the existing environment entirely and selecting a completely new environment that better accommodates one's values and capabilities.
