Does genetics completely determine behavior?
Genetic Determinism vs. Free Will
Genetics can predispose certain behaviors, but they don’t determine everything.
The environment, life experiences, and choices also shape behavior.
No, genetics predispose behaviors, but environment and choices also play a role.
It’s difficult to identify exactly how much each factor contributes.
Example:
A person may have high IQ genes, but without education, they won’t reach their full potential.
Nature vs. Nurture: The Combination of Genetics and Environment
Some traits are a mix of both:
Intelligence: Has a genetic basis but can be enhanced with enriched environments and cognitive stimulation.
Addiction: Has a genetic component, but social pressure and access to substances also play a role.
Mental Health: Conditions like depression and anxiety may have genetic roots, but stress and social relationships can trigger or modulate them.
Key Idea: Free Will vs. Determinism
Genetic Determinism = “You are what your genes say you are.”
Free Will = “You can shape your destiny.”
Reality? Both interact. Genetics may set limitations, but the brain’s plasticity and adaptability allow us to change.
What is brain plasticity?
The brain’s ability to adapt and change, even when damaged.
Example:
If the left brain is damaged, the right brain may take over some of its functions.
What is elicited behavior?
A behavior that is triggered by a stimulus.
Example:
Dust in the nose → Sneezing.
What is a reflex?
A fast, automatic response to a stimulus.
Reflexes follow a Stimulus → Response (S-R) pattern.
Example:
Touching fire → Pulling hand away immediately.
What are the three parts of the reflex arc?
Sensory neuron – Detects stimulus.
Interneuron – Passes signal to motor neuron.
Motor neuron – Activates muscles for response.
Example:
Step on a sharp object → Reflex arc pulls foot away instantly.
How is learning like sculpting a wooden statue?
Learning is easier and more effective when it works with natural tendencies, just like a sculptor must follow the natural shape and grain of the wood instead of carving against it.
Example:
Teaching a child to speak a language is easier at a young age because their brain is naturally wired to absorb language.
What are key survival reflexes in babies and mothers?
🔹 Feeding Reflex (Rooting & Sucking) – Baby turns toward touch and sucks to find milk.
🔹 Breathing Reflex – Baby moves head and cries if airflow is blocked. (RESPIRATORY OCCLUSION REFLEX)
🔹 Milk-Letdown Reflex – Mother’s body releases milk when baby suckles or cries.
📌 Key idea: These reflexes help babies feed and breathe automatically.
What are Modal Action Patterns (MAPs)?
Instinctive behaviors that are unique to a species and triggered by specific stimuli.
Example:
Gull chicks automatically peck at a red spot on their parent’s beak to get food.
What is a sign stimulus?
A specific external cue that triggers an automatic behavior.
Example:
A mother duck moving makes ducklings follow her (imprinting).
A newborn baby automatically starts sucking when something touches its lips.
This ensures that babies get food without needing to learn how to suckle.
What is a supernormal stimulus?
A stronger-than-normal version of a sign stimulus that causes an exaggerated response.
Supernormal stimuli are like junk food for the brain—they trigger extreme responses by exaggerating what we naturally like.
Example:
Fast food is loaded with sugar and fat, making it more tempting than natural food.
Artificially bright eggs make birds prefer them over their real eggs.
What did Tinbergen & Perdeck discover about gull chicks?
The key stimulus was a long, thin, downward-pointing object with a red spot.
The color of the bill (yellow), head shape, and parent’s sounds DIDN’T matter—only the red spot triggered pecking.
💡 Think of it like this:
Just as a vending machine only works when you insert the right coin, gull chicks only peck when they see the correct beak pattern
What is sequential organisation of behaviour?
Actions happen in structured steps to achieve a goal.
Actions don’t occur randomly—they follow a specific order.
These sequences are often automatic and predictable.
Example:
Squirrels follow steps to find and eat nuts.
What is the difference between appetitive and consummatory behaviour?
Appetitive = Finding/Preparing (Flexible).
Behaviours that bring an organism in contact with a goal or stimulus.
🔹 Characteristics:
More flexible and shaped by learning.
Can change based on the environment or situation.
Consummatory = Doing/Finishing (Instinctive).
Behaviours that complete a goal, often instinctive.
🔹 Characteristics:
More fixed and less flexible.
Happens the same way in all members of a species.
(seen as the end of a sequense)
Example:
A tiger stalks prey (appetitive), then bites and eats it (consummatory).
How is making coffee an example of sequential behaviour?
It follows a step-by-step process to reach the goal.
Example:
1️⃣ Get a cup.
2️⃣ Add coffee & water.
3️⃣ Brew, pour, stir, and drink.
Why do appetitive behaviours change more than consummatory behaviours?
Appetitive behaviours depend on the situation and can be learned, while consummatory behaviours are instinctive and stay the same.
Example:
Finding food varies, but eating food does not.
A human may hunt, farm, or go to a grocery store to find food (appetitive).
But no matter how they get the food, they still chew and swallow it the same way (consummatory).
📌 Key idea: The way you search for food may change, but the way you eat is always the same.
What happens to behavior when we experience the same thing repeatedly? Habituation
It changes—it can either decrease (habituation = We stop reacting as much.) or increase (sensitization = we react even more).
What is habituation?
A decrease in response after repeated exposure to the same stimulus. The opposite is sensitization where it increases.
Example: Birds stop reacting to a scarecrow over time.
What is sensitization?
An increase in response to a repeated stimulus.
Example: A dripping faucet gets more annoying the longer you hear it.
How did Epstein et al. (1992) study habituation?
People salivated less after repeated exposure to lemon/lime juice (habituation), but salivation returned when the flavor changed.
Example:
First bite of chocolate is amazing, but the 10th bite isn’t as exciting.
What is (hedonic rating)
How much they liked the taste
How do babies show habituation?
They look at new objects longer but lose interest in repeated ones.
Example:
A baby stares at a new toy but ignores it after seeing it many times.
What did Bashinski’s study on visual attention in infants find?
Babies lost interest in simple patterns faster than complex ones.
Example:
A baby stares longer at a colorful picture than a plain white wall.
