Intelligence pt2

1. Gender Differences in Intelligence

• Brain Volume and IQ:

  • Correlation: Brain volume is positively correlated with IQ performance in both males and females. Larger brain volume, particularly in certain regions like the prefrontal cortex, is associated with higher cognitive abilities.

  • Gender Differences: Male and female brains have different structural properties. For example, males tend to have larger brain volumes overall, but females often have thicker cortices in certain areas, which may relate to differences in cognitive processing.

  • Further Reading: Burgaleta et al. (2012) discuss how brain structure differences between genders may contribute to variations in cognitive performance.

• Variability in Intelligence:

  • Men Show Greater Variability: Men tend to have a wider range of IQ scores compared to women. This means that while men are more likely to be found at both the very high and very low ends of the IQ spectrum, women’s scores are more clustered around the average.

  • Implications: This variability may explain why men are overrepresented in both high-achieving fields (e.g., STEM) and in certain cognitive disabilities.

• Different Cognitive Abilities:

  • Spatial vs. Verbal Skills: Men often perform better on tasks requiring spatial reasoning (e.g., mental rotation), while women tend to excel in verbal tasks (e.g., language fluency).

  • Skewed Tests: Intelligence tests can be designed to favor one gender over the other. For example, a test heavy on spatial reasoning may favor men, while a test emphasizing verbal skills may favor women.

2. Measuring Intelligence

• Cattell’s Culture Fair Intelligence Test:

  • Purpose: Designed to minimize cultural and educational biases, this test focuses on measuring the general factor of intelligence (g), which is thought to underlie all cognitive abilities.

  • Components: The test includes non-verbal tasks, such as pattern recognition and logical reasoning, to ensure fairness across different cultural backgrounds.

  • Criticism: While it aims to be culture-fair, some argue that no test can be entirely free of cultural influence.

• High IQ but Poor Multitasking:

  • Neurological Patients: Some individuals with high IQs struggle with everyday tasks, especially if they have damage to the frontal lobes, particularly area 10, which is involved in multitasking and executive functioning.

  • ADHD Connection: Individuals with ADHD often have high IQs but may struggle with tasks requiring sustained attention and multitasking, highlighting the distinction between raw intelligence and practical cognitive functioning.

  • Further Reading: Shallice and Burgess (1991) discuss how damage to the frontal lobes can impair real-world functioning despite high IQ.

3. Creativity and Intelligence

• What is Creativity?:

  • Originality: The novelty of an idea or solution. For example, coming up with a completely new way to solve a problem.

  • Effectiveness: The practical utility of an idea. An original idea is only creative if it is also useful.

  • Convergent vs. Divergent Thinking:

    • Convergent Thinking: Finding a single correct solution (e.g., solving a math problem).

    • Divergent Thinking: Generating multiple possible solutions (e.g., brainstorming ideas for a new product).

• Divergent Thinking Test:

  • Task: Participants are asked to generate 10 words that are as unrelated as possible. This tests their ability to think flexibly and creatively.

  • Scoring: Responses are scored based on fluency (number of ideas), originality (rarity of ideas), elaboration (detail in ideas), and creative strength (diversity of ideas).

• Creativity Decline:

  • Torrance Tests of Creative Thinking: These tests have shown a decline in creativity across multiple dimensions, including fluency, originality, and elaboration.

  • Possible Causes: Increased focus on standardized testing, reduced opportunities for free play, and less encouragement of creative thinking in educational systems.

  • Further Reading: Kim and Pierce (2013) explore the reasons behind the decline in creativity.

• Sawyer’s Stages of the Creative Process:

  1. Find the Problem (Ask): Identifying a problem or question that needs solving.

  2. Acquire Knowledge (Learn): Gathering information and learning about the problem.

  3. Gather Related Information (Look): Researching and exploring related ideas.

  4. Incubation (Play): Letting the mind subconsciously process the information.

  5. Generate Ideas (Think): Brainstorming possible solutions.

  6. Combine Ideas (Fuse): Merging different ideas to create new solutions.

  7. Select the Best Ideas (Choose): Evaluating and choosing the most promising ideas.

  8. Externalize Ideas (Make): Bringing the idea to life in the real world.

• Creativity and Intelligence Correlation:

  • Threshold Theory: Below a certain IQ level (around 120), intelligence and creativity are positively correlated. However, above this threshold, higher intelligence does not necessarily lead to higher creativity.

  • Brain and Creativity: Creativity is not localized to a single brain region but involves a network of areas, including the prefrontal cortex and default mode network.

4. Types of Creativity

• Big-C Creativity: Exceptional creativity seen in geniuses like Einstein or Mozart. This type of creativity often leads to groundbreaking achievements.

• Little-c Creativity: Everyday creativity, such as finding a new way to organize your workspace or solve a household problem.

• Mini-c Creativity: Personal, developmental creativity, often seen in children as they explore and learn about the world.

• Pro-c Creativity: Professional-level creativity, seen in experts who have mastered their field (e.g., a chef creating a new recipe).

• T Factor: General aesthetic taste, which is linked to intelligence, creativity, and personality. People with high T factors tend to have a strong sense of beauty and artistic appreciation.

5. Creativity in the Workplace

• Factors that Foster Creativity:

  • Freedom: Employees need the freedom to explore new ideas without fear of failure.

  • Autonomy: Allowing individuals to take ownership of their work fosters creativity.

  • Good Role Models: Seeing others succeed creatively can inspire employees.

  • Encouragement for Originality: Organizations should reward innovative thinking.

  • Freedom from Criticism: A supportive environment where ideas are not immediately judged encourages risk-taking.

• How to Become More Creative:

  • Study Past Work: Understanding what has been done before can spark new ideas.

  • Work Hard: Creativity often requires persistence and effort.

  • Find a Mentor: Learning from someone experienced can accelerate creative growth.

  • Avoid Overspecialization: Broad knowledge across domains can lead to cross-fertilization of

6. Personality and Intelligence

• HEXACO Model:

  • Honesty-Humility: Tendency to be fair and genuine.

  • Emotionality: Sensitivity to emotional stimuli.

  • Extraversion: Sociability and assertiveness.

  • Agreeableness: Tendency to be cooperative and compassionate.

  • Conscientiousness: Self-discipline and organization.

  • Openness: Willingness to experience new things and think creatively.

  • Sadism: Deriving pleasure from inflicting pain or suffering on others, either physically or intellectually.

7. Emotional Intelligence (EI)

• Definition: The ability to recognize, understand, manage, and utilize one’s own emotions and those of others.

• Importance: EI is crucial for success in personal relationships, professional settings, and overall well-being. It helps in stress management, decision-making, and conflict resolution.

• Measuring EI:

  • Self-Report Measures: Such as the Emotional Intelligence Appraisal or MSCEIT.
