Units 1 and 2 Flashcards
what is the mind body discussion.
the mind body discussion talks about the relationship between the mind and the brain.
what is brain ablation
brain ablation was a method of figuring out what part of the brain control what by removing or damaging it.
what is Phrenology
Phrenology is a way of reading what a persons personality is by feeling their skull and seeing what parts of the brain were bigger
what imaging techniques are used to investigate the structure of the brain
MRI and CT use magnetic fields and radio waves the map the brain
what imaging techniques are used to investigate the function of the brain
MRI and PET scans use haemoglobin and oxygen to form pictures.
what is invasive brain research
invasive brain research involves opening up the brain and looking inside
what is non-invasive brain research
non-invasive brain research is scanning the brain from the outside.
what is the central nervous system
the central nervous system is the brain and spine.
what are the three principal functions of the nervous system
sensory input, integration and motor output
what is sensory input
when the nerve detects a change in environment and send it to the brain
what is integration
Integration is the thought process where the body decides what to do
what is motor output
The response that occurs when your nervous system activates parts of your body
what are the two parts of the nervous system
The central and peripheral
what makes up the central nervous system
The spinal cord and brain
what makes up the peripheral nervous system
all the nervous that branch off from the brain and spinal cord
what are the two jobs of the peripheral nervous system
Sensory detects what is going on in its surroundings and motor moves the body

what is psychology
the scientific study of the human mind and its functions, especially those affecting behaviour in a given context.
who was sperry
Sperry was a psychologist that looked into split brain experiments on cats monkeys and humans to find the functional differences between the two hemispheres.
what are the differences between the left and right hemispheres
language skills are primarily located in the right hemisphere while spatial reasoning and mechanical skills are associated with the left.
what are the different brain areas
there is the hindbrain midbrain and fore brain.
what is the main function of the hindbrain
it is the primitive brain it takes care of breathing, heart beat, balance and sleep.
what is the main function of the midbrain
The midbrain is called the feeling brain it is what makes you feel happy, angry or sad it also makes connections with, images, sounds and situations with emotion. It also connects the hindbrain to the forebrain
what is the main function of the forebrain
The forebrain controls higher order thinking like, problem solving, memory, planning and language.
what are the for lobes and where are they located
frontal, parietal,occipital and temporal. they are all located in the fore brain and going in a clockwise circle in the order listed.
frontal lobe
the frontal lobe handles high order thinking like motor function, problem solving, spontaneity, language and many more.
parietal lobe
The parietal lobes contain the primary sensory cortex which controls sensation (touch, pressure).
occipital lobe
The occipital lobe is the visual processing area of the brain.
temporal lobe
The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception
which hemisphere controls spatial awareness
the right
what does the motor cortex do
The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements.
what is development?
Development refer to the changes that occur over time.
How do we break up a life span.
into 6 different categories infancy, childhood, adolescence, adulthood, middle age and old gae.
what are the four different types of development.
physical, cognitive, social and emotional.
What is the great debate.
the debate of if it’s our environment or our genetics that shape who we are.
does nature shape us or nurture
we now think it’s both, but we don’t know which one does it more.
Qualitative vs quantitative data
Qualitative data is descriptive data eg the level of browns of chocolates where as qualitative data is about numbers eg how many pandas live in china.
what are the different types of sampling
- convenience sampling the most accessible people.
- random sampling everyone in the population has an equal chance of being picked.
- stratified sampling first organised your population into groups then pick, people from the groups to make samples with the same ratio of the groups to the population.
Extraneous and confounding variables
extraneous variables are the ones that the experimenter didn’t account for, confounding variables are more IV’s that affect the DV for example order effects.
Experimenter Effect
what bias does the experiment have on the results, so the placebo but for experimenters. that’s why double blind experiments are a thing.
what are the four stages of development according to piaget.
- Sensorimotor, Birth to 18–24 months old, Object permanence, 2. Preoperational 2 to 7 years old Symbolic thought, 3. concrete operational, 7-11, operational thought, 4. formal operational, 11-21 abstract thought.
what does a stage consist of according to piaget.
an age it takes place in and a goal that you have to complete before you move onto the next one.
what are erikson’s 8 stages of development
trust and mistrust 12-18 months, autonomy vs shame 18-3 years, initiative and guilt 3-5, industry vs inferiority 5-12, identity vs identity confusion 12-18, intimacy vs isolation 18-25, generativity vs stagnation 25-65, integrity vs despair 65+.
study sleep wake disorders
yes
what is the difference between a motor and sensory neuron.

what are synapses
synapses are the gap between neurons that a chemical, neurotransmitter are sent across,
what is the function of a synapses.
they are the messages, between neurons, they are the connections that make us who we are.

what does the retina do
the retinal changes the light into electrochemical signals so that your brain can interpret them as sight
what does the optic nerve do
the optic nerve sends the electrochemical signals to your brain.
what does the lens do
the lens helps bend to light onto your retina so that you can focus.
what does the Pupil do
it lets light enter the eye
what does the cornea do
the cornea focus some of the light and is the protective layer for the eye
what does the the aqueous humor dor
it is the liquid that fill the eye and give it the round shape.
label the eye

what is gestalts first principal.
proximity, how we group object because of the proximity to each other.
what is gestalts second principal
similarity, stuff that looks alike are put together.
what is gestalts third principal
common fate, things that move together are grouped together.
what is gestalts fourth principal
good continuation, it’s weird but our eyes follow curded lines.
what is gestalts fifth principal
closure, our brains finish the image
what is gestalts sixth principal
relativity and figure ground, relativity is the difference between one types of space and another, figure ground is our ability to distinguish the figure from the background
what is gestalts seventh principal
law of pragnanz, our brain seeing the most stable shape, so square not x’s also watch https://www.youtube.com/watch?v=yadmpXUQ68A&feature=emb_title&ab_channel=StopConfusionAnimations
sensation vs perception
sensation is what is out there and perception is how we see it.
what is the first step of sensation.
reception, when our eye detect something
what is the second step of sensation
Transduction, when the eye turns light into an electrochemical signal
what is the third step of sensation
transmission, when the electrochemical signal is sent to the brain.
what is the first process of perception
selection, feature detectors in the optic nerve filter the information
what is the second step of perception
organisation, when your brain organises the electrochemical signals into meaningful image.
what is the third step of perception
when our brain process what we see and give it meaning.
what is the ames illusions
an illusion that only lets you use one eye to look at a room with a slanted floor and ceiling, it gives the perception of changing an object’s size.
what is bullying
an unwanted, inappropriate use of power over another person, repeated over time.
what are the four types of bullying.
direct physical, when you get punched, direct verbal when you get insulted, covert when someone lies about you and cyberbullying anything mean said online about you.
what are the effects of bullying
physical, social and psychological
what is the tri-component model
a model of our attitude
what does the tri-component model include
affective, what you feel, cognitive, what you know and behavioural, how you act
what is the error of the tri-component model
people sometimes act differently to how they feel or what they know.
what is prejudice and discrimination
prejudice and discrimination is disliking someone because they’re different.
what is the difference between prejudice and discrimination
prejudice is a feeling while discrimination is an act
what was the stanford prison experiment
was an experiment conducted by philip zimbardo he looked into the power dynamic between inmates and guard and if power turned guard brutal or if humans were just brutal, he also looked into if it was the conditions the guards were in or the personality of the guards.
what is the muller effect
the muller effect is an optical illusion that makes lines look different sizes because of the direction of the arrow on it’s head and tail.
what are the five pictorial depth cues
linear perspective, interposition, texture gradient, relative size and height in the visual field.
what is linear perspective
is the convergence of parallel lines eg as train tracks get closer together they look further away.
what is interposition
when one object obscures another, the one being obscured seems further away. you can’t tell how far apart they are.
what is texture gradient
the more defined an object is the closer they seem
what is relative size
the smaller an item seems further away, this only works if all the objects are the same size when lined up next to each other.
what is height in visual field.
the higher up an object is the further away it seems.
what is perceptual set
perceptual set is our predisposition to perceive things based on our previous experiences. our expectations of what an object will be affects the outcome as well.
what are the five factors affecting of perception
contexts, motovation, emotional state, past experience and culture
what is context
the setting or environment in which the perception is made, you can identify a teacher at school but madye not at the shops.
what is motivation
motivation is what you want to see, so if you go to a game where your team is winning then it might be a fair and good game but to the losing team it isn’t.
what is emotional state
how we are feeling, so if you are scared of ghosts you might see ghosts in the dark but if you aren’t you might not.
what is past experience.
what you have seen in the past, this was explored by the rat man experiment, people were should four facing then an ambiguas shape and they said it was a face, then another group of people where should animals then the same shape they said it as a rat.
what is culture
culture is a way of life for a group of people that make them different to others, some culture have experienced western technology like photographs so they can’t recognise objects in photographs.
what was milgram’s experiment
milgram’s experiment was an experiment that looked into obedience, this experiment involves an experiment posing as a learner that gets shocked by the teacher for every wrong answer, later in the test the learner stops answering and the teacher continues to shock them 50% of the time. this experiment makes you wound how far people would go under the guidance of an authority figure.
