PS123 Psychology in the Real World Flashcards
Define free will
Free will can be defined as the ability to be free from one’s past and yet to simultaneously act in accordance with one’s will
The Compatibilists
Who held the belief that free will is compatible with a deterministic universe
The Libertarians
Who held the belief that free will is compatible with a undeterministic universe
Why is the study of free will important?
Psychology is often the study of people’s biases: what they will do and why
Punishment/blame what should we blame people for?
Self construction is important and understudied - How do I decide who I am?
Narratives influence economics, self-control, self-fufiling prophecies - narratives can be deterministic
Cognitive science
The letter opener
The parable of the letter opener - getting it through airport security?
In the face of adversity - the mind looks for alternatives to solve the issue
Turning the letter opener into a bracelet shape - looking for alternatives
What is determinism?
The belief that the past predicts the future
What are the four different stances philosophers have about free will and determinism?
Hard determinists - no free will and world is deterministic
Compatabilists - free will but the world is deterministic
Hard indeterminists - no free will and the world is indeterministic
Libertarians - free will and the world is indeterministic
The paradox of free will
Free will can be defined as the ability to be free from one’s past and yet simultaneously act in accordance with one’s will
But to have will is to have a historical identity and to be free is to somehow be ahistorical
Release the philosophers (how do we escape from our conditioning?)
Self awareness - “The Real Self view” (Wolf, 1992)
Consciousness, effortful (executive processing) - the worry is that “the casual change leading up to our actions bypasses the self” (Knobe and Nichols, 2011)
Design features of free will
- The capacity to do otherwise
- Wanting what you want
- Rational dileberation - thinking about alternatives
- Self-awareness
- Consciousness - “the casual change leading up to our actions bypasses the self” the worry is how much choice do you have over your decisions
The capacity to do otherwise
When there are less resources organisms will turn and change direction rapidly to reach a favourable environment (kineses)
Thorndike’s puzzle box - the cat’s behaviour becomes more systematic as they find how to escape the box. Initially they use random behaviours to escape by the trial and error method.
Unpredictability in adversarial interactions - how to escape predators
Wasps will fight over a place to lay their eggs - wasps will fight for a certain amount of time and then give up but the time (escalation games) varies to create unpredictability tunable randomness
This is the Hobbesian capacity to do otherwise.
Exploration vs exploitation
An animal initially exploits its original and current environment but then explores when needing new resources. This is why organisms like Caenornabditis Elegan make faster and more unpredictable movements in different directions.
Where does randomness come from?
Channel noise - channel proteins are susceptible to change like temperature they are not always predictable
Neuromodulators - norepinephrine/adrenaline and dopamine
Sensitivity to initial conditions at edge of chaos - sensitive to arbitrary small changes
Quantum fluctuations? - non-deterministic sensitive to differences of ‘arbitary small size’ - if this is true we have libertarian free will
Baddeley - random number generation
Produce a series of random digits
Add a parallel task (cognitive load) remember a sequence of numbers (many distracting tasks will achieve the same thing)
More load more redundancy
Redundancy
A measure of reduction from maximum entropy by repeating transitions between numbers
Vicarious Trial and Error Learning - Tolman and Gleitman (1949)
Puts rat in the maze allows it to explore
It shocks the rat in a dark space
It is put back into the maze and it stays in the light section
In the T maze the rat stays in the middle of the T before making a decision to go to light or dark end
The rat is actually thinking about its future
How do they know rats are thinking about the future?
Record the ventral striatum - which is associated with reward
HC is hippocampal place cell associated with a physical place
They even record rats sleeping and dreaming about the choice point in the T maze the rat dreams about their movements in the maze
Episodic future thinking
Using knowledge you already have in a new context and situation e.g another study shows that the rats are able in a more complex maze to think about paths they haven’t even taken
Hippocamapal damage
Individuals who suffer from hippocampal damage have difficultly recalling recent events and difficulty imagining future events
Cognitive maps and tunable randomness suggest we have free will
The self - reality monitoring
Reality monitoring - do you know what’s real?
“Now I do not know whether I was then a man dreaming I was a butterfly or whether I am now a butterfly, dreaming I am a man” - Chuang-tzu
Reality monitoring - we suffer from it during our dreams, some people suffer from it all the time - older adults have more problems than younger adults but they both have them - age-related deficits in reality monitoring of action memories (McDaniel et al. 2008)
How do we monitor reality?
The self-actuating model - when you think about something you haven’t done you find away to remind yourself of who you are
This model knows the difference between real and imagined events - it knows that the stimulation is not a real experience
True or false patients with hippocampal damage report having a degraded sense of self
True - Hippocampal damage - patients with hippocamal damage struggle remembering the past and imaging the future reported having a degraded sense of self
Do older people become more or less predictable
More - less choice
People with better imaginations are better at reality monitoring
False people with better imaginations have more difficulty with reality monitoring
