6-6 Psych
Biological, Cultural, and Psychological Factors in Learning
Contributions to Learning
- Albert Einstein's Talents
- Combined creativity with analytic ability, leading to significant insights in physics.
- Exceptional intellectual skills attributed to both biological (genetic endowments) and cultural (education, environment) factors.
- Raises the question of whether Einstein could have thrived in a less favorable environment.
Biological Constraints on Learning
Physical and Structural Limitations
- Different species have unique biological traits that both enable and inhibit learning.
- Examples:
- Humans cannot breathe underwater.
- Fish cannot ski, indicating species-specific abilities.
- Chimpanzees cannot speak human languages due to lack of vocal equipment.
Instinctive Drift
- Defined as the tendency of animals to revert to instinctive behaviors that interfere with learned behaviors.
- Example: Keller and Marion Breland's training experiments (1961) with pigs and raccoons:
- Pigs dropped wooden nickels on the ground, showing rooting behavior instead of placing them in a bank.
- Raccoons retained coins instead of depositing them, demonstrating instinctual food washing behaviors.
These examples highlight how instinct can override learned behavior despite reinforcement efforts.
Preparedness in Learning
Definition: Preparedness
- A species-specific biological predisposition to learn in certain ways.
- Some associations are learned more quickly than others due to biological factors.
Taste Aversion Learning:
- Research by Garcia and colleagues (1989) highlights how a single trial can create a lasting aversion to a food that caused nausea after low radiation exposure.
- Long-term aversion contradicts classical conditioning, which implies repeated pairings are needed for lasting learning.
- This type of preparedness is evident in both animals and humans when choosing food based on taste and smell.
Fear and Conditioning:
- Studies show both monkeys and humans have a natural predisposition to fear snakes, indicating preparedness for associating certain stimuli with fear (Oz et al., 2018; Burtles et al., 2018).
- In classical conditioning settings, snakes (CS) paired with electrical shocks (US) led to strong fear responses (CR), demonstrating rapid learning.
- Observational learning: Lab-raised monkeys learned to fear snakes by observing others who expressed fear, even without prior experience with snakes (Omen et al., 2003).
Evolutionary Implications:
- Preparedness for fear of snakes likely evolved as a survival mechanism, emphasizing the danger posed by reptiles in ancestral environments.
Cultural Influences on Learning
- Understanding Cultural Context:
- Traditionally underappreciated in animal learning studies, it raises the question of culture's impact on human learning.
- Learning content is influenced by cultural experiences, as one cannot learn about things they have not encountered.
- Example: A child from the Kalahari Desert may not learn to use a knife and fork, while a Chicago child may lack skills in tracking animals.
- Skill Development:
- Children’s skills often reflect the practices prevalent in their culture. For example:
- Balinese children are often dancers by age six.
- Norwegian children may excel in skiing and skating at the same age.
Psychological Constraints on Learning
Mindset Theory (Carol Dweck, 2006)
- Defines mindset: beliefs about one's abilities influence goals and learning outcomes.
- Fixed vs. Growth Mindset:
- Fixed mindset: Belief that abilities are static and unchangeable; failure is seen as a reflection of inherent inability.
- Growth mindset: Belief that abilities can develop through effort; failure is viewed as a learning opportunity.
- Implications for success in academic settings, particularly in challenging subjects.
Effects of Mindset on Academic Performance:
- Study on first-year pre-med students showed those with a growth mindset achieved higher grades compared to fixed mindset peers, recovering better after setbacks.
- Fixed mindset students typically resorted to rote memorization and often gave up on challenging subjects like chemistry, whereas growth mindset students engaged more actively with the content.
Mindset Interventions:
- Research by Dweck and colleagues aimed at improving student motivation and achievement, emphasizing a growth mindset.
- Effectiveness of mindset interventions showed improvement in math achievement when students understood the brain's capacity to grow and change with effort (Blackwell et al., 2007).
Effective Strategies for Developing a Growth Mindset
- Acknowledge that intelligence and skills can change over time with effort and commitment.
- Foster a passion for learning, embracing challenges as opportunities for growth.
- When facing obstacles, focus on persistence and the development of new strategies for success.
- Reflect on the journeys of accomplished individuals, recognizing the hard work behind their achievements.
- Begin the transition from a fixed mindset to a growth mindset by planning actionable steps towards change.
