Q

What is classical conditioning and all of elements of classical conditioning in relation to the three phased model

A

Classical conditioning is a type of learning that occurs through repeated association of two or more stimuli

(Conditioning = learning)

Classical conditioning in relation to the three- phased model refers to the 3 stages of classical conditioning which are
- Before conditioning
- During conditioning
- After conditioning

Q

All relevant sub divisions of classical condition as a 3 phased model

A
  1. Before conditioning
    - UCS (Unconditional stimulus) is the stimulus that consistently triggers a specific natural occurring automatic response
  • UCR(Unconditionel response) Is the response which occurs automatically whenever the UCS is presented (i.e saliva)
  • NS (Neutral stimulus) does not trigger in the before conditioning stage because no learning has taken place
  1. During conditioning (Acquisition phase)
    - NS{aka CS}
    -UCR
    -UC

3.After conditioning
- CS (conditioned stimulus that was neutral at the start of conditioning process and now triggers the desired response (i.e bell)

-CR (conditioned response) The learned response that is produced by CS (i.e salivating)

Q

What is operant condition and the 3 phased model of operant conditioning

A

Operant conditioning is a type of learning where by the consequence of the behaviour determine the likelihood that it will be preformed again the the future. If behaviour will tend to be repeated if there are desirable consequences (getting a treat) or will enable an undersirable consequence

The 3 phased model is

  1. The antecedent (A) a stimulus that occurs before the behavior (the trigger), physical environment
  2. The behavior (B) That occurs because of the antecedent
  3. The consequence (C) to the behavior

Q

What is reinforcement and whats its aim with the 2 types of reinforcement

A

Reinforcement (Aims to repeat behavior)

Positive reinforcement - Occurs from giving / applying a positive reinforcement after the desired response has been made which leads to the behavior being repeated in the future

Negative reinforcement- Is the removal or avoidance of an unpleasant stimulus, it too has effects of increasing the likelihood of a response being repeated

Q

What is punishment and the 2 main types of punishment

A

Punishment is aiming to NOT repeat behavior

Positive punishment- Involves providing a stimulus to decrease the likelihood of a response occurring again e.g. Smacking a child

Negative punishment- Involves the removal of a valued/ desired stimulus which reduces the likelihood of a response being repeated e.g taking an Ipad

Q

Differences between negative reinforcement with forms of punishment

A

Remember reinforcement should be associated with repeating behavior so if we wanna repeat behavior it is negative reinforcement.

Negative reinforcement involves removing/ avoiding something unpleasant/negative (e.g. speeding fine) so behavior of driving the speed limit can be repeated

Punishment involves applying something unpleasant/negative like pepper on somebody tounge or removing something vluble (tacking away phone) so that a behavior is not repeated in the future (wont swear anymore or wont use phone when not allowed)

Q

What is observational learning and the elements of observational learning +all relevant terminology

A

Observational learning occurs when somebody uses observations of another person actions and their consequence to guide their future actions

Attention
Retention
Reproduction
Motivation
Reinforcement

Model=Person being observed
Often a person with status or image is a desired model
At other times the model is not the motivation arises from a need to know
‘Vicarious means learning through observation

Q

What is attention in relation to observational learning, what stage is attention in observational learning

A

Attention is- In order to learn through observation we must closely watch the models behavior in order to recognize the distinctive feature

A couple factors are
- Perceptual capabilitys of the observer (seeing)
- Motivation and intrest of observer
- Sitution in which behaviour is being observed ‘
- distractions

Q

What is retention in relation to observational learning

A

Having observed the model we must be able to remember the models behavior sometimes behavior that is learned through observation is not needed immediately in which case it is stored memory’s until required

Linking a visual image with a verbal description is an efficient strategy to assist the memory process

Q

What is reproduction in reference to observational learning

A

When the models behavior has been closely attended to and retain memory, we can attempt to imitate what has been observed

We must have the ability/ comperity ti put into practice what we have observed (remembered)

Q

Motivation- reinforcement in relation to observational learning and the aspects to reinforcement

A

Learner must also be motivated to preform the behavior unless the behavior is useful or provides a reward, it is unlikely that it is learner will want to learn the behavior in the first place

Aspects to motivation through the following form of reinforcement
- External reinforcement
- Vicarious reinforcement
- self reinforcement

Q

What are songlines

A

(AKA dreaming tracks) are travel routes that consist of a series of locations and/or landmarks, most of which have a story, song, dance or ceremony attached to it

By describing and/or walking the songline, an individual is exposed to each story song dance and ceremony. In turn the individual can acquire a massive amount of info on things like plant life native animals land formations land use, trade, medicine rights and responsibility

Q

What is sensory memory

A

Sensory memory is new sensory information that is in the form of sight, sound ,taste, smell and touch. Therefore sensory information is tge entry point of new information into the memory system . Info is held here just long enough for it to be encoded unto a useable form and then transfer into STM

Q

What are the 2 types of sensory information and the duration of these types of sensory information?

A
  1. Iconic memory- The name given to visual sensory information
    Visual images in their original form are usually retained in iconic memory for 1/3 of a second. E.g if looking at a flower and you close your eye you can imagine a image of the flower, this will happen for 1/3 of a second for encoding
  2. Echoic memory- The name given to auditory sensory information. (called echoic memory

Echoic memory stores info for 3-4 seconds. So it stores for longer than iconic memory, auditor info must also be held for long enough for long enough for all parts of speech within a list of words to be identified

20
Q

How long does iconic and echoic memory last in duration (quick)

A

Iconic (visual memory) 0.2-0.4 seconds 1/3 of a second

Echoic memory is about 3-4 seconds

21
Q

What is short term memory

A

STM stores a limited amount of info for a brief period unless the information is described as a ‘temporary working memory ‘ in which we manipulate information that is held to preform everyday functions. It holds the information that we are consciously aware of ay any given time (receives information from the sensory register as well as retrieving previously stored info from long term memory)

22
Q

Capacity and duration of STM

A

Capacity- It has a limited capacity and can only hold around 7+2 items (5-9 items) of info at a time

Duration- STM holds info for up to 30 seconds unless a conscious effort is made to keep it there longer. There is achieved through rehearsal and at 18-20 seconds we have almost lost all info

23
Q

What is rehearsal and the 2 types of rehearsal (It can increase STM)

A

Rehearsal- Rehearsal is the process of actively manipulating information so that it can be retained in memory

Maintenace rehearsal- Involves repeating the information being remembered over and over again to retain in short memory

Elaborative rehearsal- Is the process if linking new info in a meaningful way with information already stored in memory or with other new information to aid in it;s storage and retrieval from long term memory e.g. mind mapping

24
Q

Long term memory (LTM)

A

The long term stores hold information relatively permanent in a highly organized way and has essentially an unlimited capacity

information in LTM can be stored forever

25
Q

What are all sub divisons of long term memory

A

The main types of LTM are
1. Explicit memory
- Episodic memory
- semantic memory -

  1. Implicit memory’s (procedural)
    - Procedural memories
26
Q

What are explicit memorys and all the subtypes

A

Explicit memory’s- (or declarative memory’s) are memory’s for factual specific info like names faces and events that have personal significance (e.g first day of school it is conscious memory, knowing that memory

Episodic memory- Episodic memory is the declarative memory system that holds information about specific events or personal events , Like a mental diary e.g recalling b day party

Semantic memory- Is the declarative memory system that stores the information we have about the world

Includes s[ecialised knowledge and expertise you remember the fact itself and it does not remember the place most of the time/ the place is irrelevant, like u don’t remember when you learnt that there was 12 months in a year but u know u remember it

27
Q

What are implicit memory’s and the subdivisions

A

Implicit (procedural) memory- Memorys of learnt actions and skills and does not require conscious or intentional retrieval, you are not aware you are remembering when preforming action and it happens effortlessly E.g playing table tennis

Often referred to as ‘non- declarative memories’ because people often find it difficult to state or describe in words what is being remembered but the memory can be described through behavior e.g knowing a password ‘knowing that memory

Procedural memories- Is memory of motor skills and actions that have been learned previously. It involves memories of ‘how to do something’ e.g how to use tennis racquet, usually demonstrated through behavior/ performance called kill, muscle or body movements little no effort to retrieve memory

28
Q

All of the tools and techniques for accessing info from LTM

A

Free recall- Is trying to retrieve as much information as possible from LTM, in any particular order and without the assistance of a prompt (cue). The stronger the neural pathway (LTP) the easier the recall

Cued recall- Is where we use prompt and/or retrieval cues to access information stored in LTM. Hints pictures and mnemonics are some prompts and/or retrieval cues out there, the more specific the prompt more likely info will be recalled

Recognition-Involves identifying the correct information from among a collection of options

29
Q

What are mnemonics and 3 main types

A

Are techniques/ tools that assist in the storage and retrieval of long term memories., effectiveness stems for ability to link between new info to be remembered and information that we have already stored safely away , they DO NOT simplify info instead they make things more elaborate.

3 main types
1. Acronyms
2. Acrostics
3. Method of Loci

30
Q

Define the 3 main mnemonics

A

Acronyms- The mnemonics involved creating words and/or sentences from a collection of letters, usually the starting letters of the information we are trying to remember e.g ANZAC

Acrostics- An acrostic is a sentence where the starting letter of each word match’s the starting letters of the items to be remembered strangely enough the quicker the sentence to more likely to be remembered

Method of loci- Involves linking/ tagging the items to be remembered with a specific position or location in a well known area, area could be small or large

31
Q

What are songlines (dreaming tracks)

A

Are navigational routes that consist of a sequence of locations and/or landmarks most of which have a story, song, dance ect

NOTE: Oral memory system

By describing and/or walking the route an individual is exposed to story song ect and can learn massive amounts of info

32
Q

All various structures of the brain

A
  • Neocortex
  • Amygdala
  • Hippocampus
  • Cerebrum
  • Basal ganglia
33
Q

What does the neocortex to and what is it

A

The neocortex (aka cerebral cortex) is the thin outer layer of the cerebrum.

Long term explicit memory’s (semantic and episodic) are stored widely throughout the neocortex. Each fragment of a memory tends to be stored in the area(s) where it was processed. Complex neuropathways allow us to experience memory’s within the neocortex

34
Q

What does the hippocampus do and where is it located , + does it store long term memory’s and role

A

The hippocampus is located deep within the brain in an area called the medial temporal lobe

The hippocampus has a vitial role in the consolidation of explicit memory’s (semantic and episodic), consolidation is making a newly formed memory stable and enduring after learning

NOTE: The hippocampus DOES NOT store memory’s long term, the consolidation process enables information and memories to be successfully stored in neocortex

Damaged hippocampus DOES NOT prevent the creation of procedural or classically conditioned memory’s, evidently these memories are created and stored in other section

35
Q

What is the amygdala

A

A small structure sitting just above the hippocampus. It communicates with the hippocampus and other areas of the brain, also involved with processing and regulating emotional reactions, heavily involved in creation of emotions memories including classically conditioned fear

36
Q

What happens if the amygdala is damaged

A

Individuals tend to have difficulties processing, regulating and recalling emptions such as fear anger and aggression

There is also considerable research evidence that a damaged amygdala can leave an individual unable to learn to fear or feel threatened by dangerous things

37
Q

What is the basal ganglia

A

Basal ganglia is a set of structures near the amygdala and hippocampus

It is involved in encoding and storage of procedural memories such as habits and well practiced voluntary movements

It also accounts for why we become less responsibile to atimuli that we are repeatedly exposed to e.g getting used to loud noise in city

38
Q

What are some symptoms of a damaged basal ganglia

A
  • Difficulty starting and sustaining movement
  • Involuntary movements
  • slowed movements
39
Q

What does the cerebellum do

A

The cerebellum is located at the base of the brin and looks like another mini brain. It contains more neurons than the rest of the brain combined (high condensity)

Known to be involved in encoding and temporary storage of procedural memories that require fine muscles ,movements, balance, posture and/or sequence of movements, long term storage is held within the neocortex

DOES NOT store explicit memories

40
Q

What are some symptoms of a damaged cerebellum

A
  • Difficulty timing and controlling muscle movements
  • Poor posture
  • Balance problems
  • Difficulties getting words out
  • Loss of conditional responses piked up from classical conditioning
  • Inability to judge distance and when to stop
41
Q

What is an imagined future

A

The ability to construct an imagined futures the ability to predict what will happen or what is needed in the future

42
Q

What types of memory’s are needed to make imagined futures

A

We rely heavily on episodic and semantic memories to help construct imagined futures

43
Q

What is aphantasia

A

When somebody cannot form a mental image in there head.

44
Q

What are some reasons for aphantasia

A

Some cases on aphantasia is from birth while other reports say aphantasia happens because of brain injury or depression

Another reason could be because people with aphantasia have weaker neural pathways

45
Q

What is Alzheimer’s and what are some effects of Alzheimer’s

A

Is a neurogenerative disease characterized by the gradual and widespread degeneration ( damaged or dying)

Some effects of Alzheimer’s are memory decline, personality changes and deterioration of cognitive and social skills as the neurons die the affected brain areas will shrink and waste

46
Q

What are some of the main steps of Alzheimer’s what is effected first ect ect

A

Diseases tends to start slowly and in the early stages symptoms are subtle including confusion, irritability and STM difficulties

As the disease progresses LTM (episodic) are increasingly impaired, it is common for people to experience significant change in personality and struggle to imagine themself in hypothetical situations (no imagined futures)

Autopsy’s helped us to understand that 3/4 of neurons in the medial temporal lobe and/or hippocampus are typically lost in extreme Alzheimer’s disease

47
Q

What are the 2 structures that cause Alzheimer’s

A
  • Amyloid plaques- Hard clumps of protein that build up around the neuron impairing synapse and inhibiting communication between neurons
  • Neurofibrillary tangle Are twisted fibers that build up within a neuron and inhabit the transport of essential substances throughout the neuron
