- very few sexual dreams
- a lot of dreams are straightfoward and not symbolic
- most dreams are negatice
- post truama nightmares, repetitive nightmares, that do not involve wish fulfillment
- dreams reflect the brains attempt to make sense of random and internallt generated neural signals during REM
- pons sends incomplete signals to the thalumus witch then relay to the fore brain to try and turn signals into a story
- random and meaningless to everyday life
- damage to forebrain and parential lobes can eliminate dreams completly even when pons are intact
- dreams are consistant over time and not as random as activation synthesis theory would predict
- dreams are meaingful product of our cognitive capacities, that shape what we dream about

- interpersonal situation in which imaginative suggestions are administered for changes in consciousness
- useful in combination with other thearapys
- unsure if the improvments are hypnosis or relaxation
- contraversal
- approach that hypnotizes and supposedly age-regresses patients to a previous life to identify the source of a present-day problem
- trance state, amazing things happen, doesnt turn people into mindless robots, doesnt have a great impact on suggestibility
- no biological difference between hypnosis and wakefulness
- sleeplike state but not biologically simular
- people are fully aware of their surroundings
- people dont forget what happens unless they expect to foget everything
- increases memory but most of it is not accurate
- substance that contains chemicals similar ro those found naturally in our brains that alter consciousness by changing chemical processes in neurons
- alcohol (most common in women), barbiturates, quaalude, valium

- withdrawl may occur and distressing symptoms can occur
- tolerance is higher the more you use the substance
- physical, related to withdrawals
- psychological, intense cravings
-sociocultural and acceptance, low rates of alcohol consumption where its prohibited (muslims and mormons)
- addictive personality, impulse, sociability, proneness to negative emotions
- tension reduction hypothesis, drink/ do drugs due to anxiety and treat it as a "self medication" cycle
- genetic fsctors link to vulnerability to alcoholism
- genes can determine drug metabolism and experiences
- ALDH2 gene causes an unpleasant response to alcohol, asian flush (facial flushing, heart palpitations and nausea), lower risk of alcholism
- balanced placebo design (punnet square sitch)
- what we expect to happen while drinking plays a role in our social behaviour (aggressions)
- alcohol is more importnant in non social behaviours like reaction time and motor control
- setting is also important as you are more likley to drink more in a bar rather than alone
- healthier
- not nutritionally but better than alcohol
- not recommended for recovering alcohoclics due to simular smell and taste
- sometimes contains lower rates of alcohol
- sedative, calming
- hypnotic, sleep inducing
- assist with anxiety and insomnia
- barbiturates, abuse potential, can produce feelings of being intoxicated

- produce dramatic alterations in perception, mood and thought
- heart rate increase, red eyes, dry mouth
- chronic use can impair cognitive functions
- most used hallucinogenic drug in canada
- legal since 2018
- effects due to THC
- THC binds the same receptors as neurotransmitter anandamine that plays a role in eating, motivation, memory and sleep
- increases heart rate, red eyes and dry mouth
- chronic use can impair cognitive function
- changes perception, consciousness, sensation (synesthesia)
- produces feelings of clear thought
- some mystical experiences
-effects could be due to interference with serotonin system (affects consciousness, arousal, movements, and our readiness to respond to stimuli)
- increases communication amung brain networks that dont usually work together
- multisensory experiences and synesthesia
- decreases self esteem
- mystical experiences (sense of unity or oneness with the world)
- stimulant and hallucinogenic
- realeases serotonin promoting a sense of well-being, self confidence and empathy for others

- potential treatment for depression, drug addiction, PTSD , OCD, anxiety with late cancers
- tend to disappeasr after a few days
- short lived panic, paranoid delusions, confusion, depression and bodily discomfort
- flashbacks, recurrences of elements of a psychedelic experiences and can be disturbing
- change in organisms behaviour or thought as a result of experience
- different kinds
- habituation, decrease in response to stimuli over time and our behavioural response
- sensation, increase in response to stimuli over time
-sensory adaptation is more involuntary whereas habituation can involve deliberate control
- when we associate 2 stimuli together
- simple associations provide mental building blokcs for more complex ideas
- classical (pavlovian) conditioning, -> a form of learning in which animals come to respond to a previously neutral stimulus which has been paired with another stimulus that elicits an automatic response
- a stimulus that does not elicit a particular response
- metronome
- a stimulus that elicits a unconditional response (UCR)
- meat powder (UCS) and salvation (UCR)
- in classical confitioning we pair the neural stimuli with UCS (metronome woth meat powder)
- neural stimulus (NS) becomes a conditioned stimulus (CS) eliciting a conditioned response (CR)
- after training the metronome elicits salvation
- the organism reacts the same way to the conditioned stimulus as it did to the unconditioned stimulus
- acuisition, phase during which a conditioned response is established
- extinction, reduction of the conditional response after the conditioned stimulus is presented repeatedlt without unconditional stimulus
- after extinction, spontaneous recovery and renewal may be evident
- spontaneous reconvery, the conditional response after time passed ( no UCS-CS repairing required)
- renewal, the conditional response retuns in a novel setting different from the one in which the response was aquired (or extinquished)
- when simular conditional stimulus elicit the same conditional response
- response to tunging forks that makes the same sound
- when we exhibit a conditional response only to certain stimulius
- response to tornandos is different in movies rather than real life
- pigeons can be trained to discriminate paintings by Monet vs. Picasso
- someone scared of stinging insects (wasps/bees) may not show fear response to other insects (house fly)
- developing a conditional response that is accosuated with another conditional stimulus
- the conditional response becomes weaker farther away from the orginal conditional stimulus
- CR1 strongest C3 weakest
- flashlight (CS2)- metronome (CS1) - meat poweder (USC)- salvation (CR/UCR)
- advertisers repeatedly paur their products woth the stimuli that elicit positive emotions
- a stimulus often experienced alone may be resisitant to conditioning
- familiar stimulus more difficult to condition that an unfamiliar stimulus
- helps to explain how and why we acquire some fears and fobias (extreme, irrational fear or aversion)
- Little albert
- not afraid of animals and rats
- paired loud noises (UCS) with rats (CS)
- developed intense fear of rats
- fear response transfered to other stimuli (rabbits, dogs, furry coat, santa mask)
- treat phobias
- little peter phobia of rabbits
- paired candy (UCS) with rabbit
- eventuallt rabbit (CS) started to elicit feelings of pleasure (CR)
- treatments of phobias often pair feared stimulus with relaxation
- a conditional response that is opposie of the unconditional response and serves to compensate for the unconditional response
- heroine decreases blood pressure (UCR), therefore in anticipation of taking herion your body compensates by increasing blood pressure
- important to understand drug response
- if you always take the drug in the same room that room acts as a cue that signals drug delivery
- being in the room with initiate a defensive response ( a CCR) that prepares you to for the drugs effect
- drug overdose can occur if one injects heroine in a different place from lack of CCR
- sexual attraction to non living things
- seems to be partly due to classical condition
- trained in japanese quails
- terrycloth cylinders (CS) paired with mating (UCS)
- quails tried mating with the terrycloth cylinders (CR)
- eg, before, partner (UCS) in thier undies (CS) -> arousal (UCS)
- eg, after, undies (CS) on clothing rack cause arousal (CR) aswell
- learning wherein the frequency of a behavior is controlled its consequences (reward and punishment)
- the organism gets something because of its response (food, avoids punishments)
- target behaviour is,
classical, elicited automatically
oparent, emitted voluntarily
- behaviour is a function of,
classical, stimuli that precede the behaviour
oparent, consequences that follow the behaviour
-behaviour depends primarly on
classical, automatic nervous system
oparent, skeletal muscles
- if we are rewarded for a particular response to a stimulus, we are more likley to repeat that response to the stimulus in the future
- if rewarded most likley to do that behaviour again
- learning involves an association between a stimulus and response (S-R) with the reward establishing the connection
- performance only changes once an organism "grasps" the underlying nature of the problem
- cats time to escape from the puzzle box decreases gradually over 60 trials
- cats were learning by trial and error through the bulidup of S-R associations
- cat never abruptly realized what it needed to do to escape
- no "AHA" moment
- cats dont learn by insights (graspinf the underlying nature of the problem)
- to observe oparant behaviour unsupervised
- outcomes the stregthen the probability of a response
- positive, giving a stimulus (rat getting food from a lever press, getting A on a test, putting money in a vending machine)
- negative, involves taking away a stimulus (rat pressing a level to stop an electrical shock, cleaning your room so your paretns dont nag you, studying for a test to reduce your anxiety)
- doesnt mean good or bad
- any outcome that weakens the probability of a response
- positive, adding an (typically undesirable) stimulus to reduce behaviour
- spraying a dog with a spray bottle when it barks
- spanking a child for bad behaviour
- assigning extra homework for talking in class
- negative, removing a (typically desirable) stimulus to reduce behaviour
- taking away a childs toys for bad behaviour
- taking away marks for plagiarism
- silent treatment (removing affection/ social interaction) for partying/ drinking
- disciplinary actions are punishments only if they decrease the chance of the behaviour happening again
- Positive Reinforcement
Presenting a stimulus
Increases target behaviour
Giving a gold star on homework, resulting in a student studying more
- Negative Reinforcement
Removing a stimulus
Increases target behaviour
Static on phone subsides when you stand in a specific spot in your room, causing you to stand there more often
- Positive Punishment
Presenting a stimulus
Decreases target behaviour
Scolding by a pet owner, reducing a dog’s habit of chewing on shoes
- Negative Punishment
Removing a stimulus
Decreases target behaviour
Confiscating a favourite toy, stopping a child from throwing future tantrums
- not aswell as reinforcement
- several disadvantages
- tells a person what not to do, but doesnt tell then what they should do
- creates anxiety
- encourages subversive behaviour
- makes people more sneaky about doing unwanted behaviour
- may provide a model for aggressive behaviour
- discriminative stimulus, signals the presence of reinforcement
- light in skinner box, friends wave
- acquisition, extinction, spontaneous recovery, stimulus generalization and stimulus discrimination all apply to oparent condition
- shortly after withdrawing reinforcement the behaviour increases in intensity before decreasing
- stop reinforcing a childs crying with attention, child may initilly cry even louder to get attention
- falling vending machines, after reinforcement is removed, person may ramp up their behavior by pressing more buttons, pushing buttons harder, tilting or shaking the machine
- refers to the pattern of delivering reinforcers
- the response is rewarded everytime
- occurs when we reinforce responses only some of the time
- more resistant to extinction
- very along two dimensions
- consisitanct of administering reinforcement
- fixed, reinforcemtn after a set of number responses or time
- variable, reinforcement after an average number of responses or average time
- the basis of administering reinforcement
- fixed ratio, buy 7 coffees get one free
- variable ratio, gambling, roll up the rim, video game item drops, swiping on a dating app
- fixed interval, writing a test every 2 weeks
- variable intervalm checking an email, checking if grades are on moodle
- train a new behaviour by reinforceing behaviours that get progeressively closer to the target behaviour
- baby learning to walk, reinforce crawling first, then standing, then a step then a few steps ect
- link several behaviours together
- learning to wash hands
- reinforceing turning on a faucet, apply soap, put hands under faucet, turn off faucet, dry hands
- used to teach animals complex tricks
- dolphin to jump through a hoop
- pigeon to play ping pong
- positively reinforce an infrequent behavior with a frequent behavior
- don’t watch your favourite TV show (frequent behavior) until after you do homework (infrequent behavior)
- to shape desired behaviours in clinical setting
- primary reinforcer, things that natuarally increase target behaviour (food)
- secondary reinforcer, neutral objects that become associated with primary reinforcers (money)
- applied behaviour analysis in autism, provide food and other primary reinforcers to individuals with autism as they reach closer approximations to certain words and eventually complete sentences
- two process theory of anxiety, anxiety begins with classical conditioning but is maintianed by negatvie reinforcement
- i am stung by a bee (conditional stimuli), resulting in fear (conditional response) to bees and wasps
- avoiding bees and wasps one sees, decreases anxiety (negative reininforcement)
- reinforces avoident behaviour
- face the fear
- exposure therapy, exposes people to feared stimuli
- early belivers did not believe thinking played much of a role in learning (radical behaviour)
- argued that thinking and emotions are behaviours, just convert ones
- today most psychologist acknowledge at least some role for cognition in learning
- the way an organism responds to a stimuli depends on how that organiams interprets the stimulus (meaning)
- most scientist now believe that classical conditioning and oparetn conditioning depend on thinking
- learning that is not directly observable
- difference between competence (what we know) and performance (showing what we know)
- implies that reinforcement is not necessary for learning to occur
- rats could learn a maze without reinforcement
- rats didnt show thier learning until they got their reinforcement
- rats developed cognitive maps (mental representation of how a physical spacpe is laid out) once their was a reinforcer
- challenges radical behaviourism and implies that thinking plays a role in some forms of learning
- learning by watching others (no direct experience required)
- dont have to engage in trial and error
- observing aggression
- experimental condition, children watched an adult model punch, kick and insult bobo dall
- control condition, children watched an adult play and ignore bobo doll
- when children in the experimental condition were left alone with the doll, they were more likely to perform similar aggressive acts, including using some of the same insults the adult model’s did
- many types of research have examined the impact of violent media behaviour
- results suggest media violence impacts real- world aggession in some cases
- some issues with establishing causality
- however, fair bit of converging evidence across different study designs
- differs amongst cultures (strongest relationship for white people, weaker for Asians, and nonsignificant for Latinx people)
- link is more controversial for video games
- however, media violence is only one small contributor to real-world aggression
- most people that watch violent media don’t show aggressive behavior
- become activated when an animal observes or performs an an action
- in monkeys, a group of neurons in pre-frontal cortex near motor cortex
- may play a role in observational learning and having empathy for other
- may help to feed other peoeple emotional states
- insight, grasping the underlying nature of the problem
- placed chimpanzee in cage with two bamboo sticks
- placed bananas outside the cage just out of reach of a single bamboo stick
- “sultan” (one of the chimpanzees) found the solution -> sticking one bamboo stick into the other
- “aha! moment” -> Chimps didn’t learn by trial-and-error like the cat’s in Thorndike’s puzzle box
- once chimps solved the problem, they could get it right every time
- suggests humans and some other animals may gain insight
- conditioned taste aversion
- develops after only one trial
- learning is still possible even with very long delays (6-8 hours)
- shows little stimulus generalization
- contradicts equipotentiality -> the claim that we can classically condition all controlled stimulus equally well to all uncontrolled stimulus
- for certain phobias contradict equiptentiality
- evolutionary predisposition to be more afraid of certain things
- snakes and spiders vs. cars and guns
- may make us more likely to form certain illusory correlations
- people more likely to associate "prepared" stimuli (snakes) with aversive stimuli
- instictive drift, tendancy for animals to innate behaviours following repeated reinforcement
- raccoons were reinforced to drop coins into a piggy banks, but raccoons began rubbing the coins together (rinsing, an innate behaviour)
- biological influences, place limits on what kind. of behaviours we can train through reinforcement
- much easier to trains pigeons to peck rather than dance
- many techniques are purported to make you learn better or faster
- sleep assisted learning
- accelerated learning
- discovery learning
- non seem to be more effective than traditional learning
- direct instuction is almost always better
- been used to refer to an individuals preferred or optimal method of acquiring new information
- tailoring teaching to peoples learning styles does not result in improved learning
