Q

What is memory?

A

Memory is a mental capacity to encode, store and retrieve information. It represents our unique perceptions of events rather than being accurate or objective.

Q

What is Encoding?

A

the initial processing of information that leads to representation in memory. Its the act of getting info into our memory system through AUTOMATIC or EFFORTFUL processing. requires selection of stimulus event and making a classification of it.

Q

How do we form memories?

A

these three stages work together to transform sensory experience into a lasting record that has a pattern or meaning. It has to be processed by three stages: Sensory memory, Working memory and Long term memory.

Q

What is Sensory memory?

A

most fleeting, holds sights, smells, sounds, textures for a maximum of a few seconds. Sensory memory can hold far more information than it ever reaches the consciousness.

Q

Sensory memory into working memory

A

Visual stimulation ——> Iconic memory
Auditory Stimulation —–> Echoic memory
Tactile Stimulation (touch) —–> Tactile sensory memory
Olfactory Stimulation (smell)—–>Olfactory sensory memory
Gustatory Stimulation (taste)—->Gustatory sensory memory

Working memory

Q

What is working memory?

A

second stage of processing, takes info from sensory registers and makes connections with items already in long-term storage. holds information up to 20 to 30 seconds. originally called short-term memory (STM).

Q

Memory span

A

George Miller said that seven (plus or minus two) was the “magic number” that characterized people’s performance on random lists of letters, words…

Q

A model of Working memory

A

1) Stimulation => Sensory Memory
2) Central Executive (Working memory)
3) results in behavior.
4) devided into 1️⃣Episodic buffer(events) 2️⃣Sketchpad (visual image) 3️⃣Phonological loop( sounds) they are all LTM

Q

details of Sensory Memory

A

Function: briefly holds information awaiting entry into working memory.
Encoding: no meaningful encoding.
Storage capacity: 12-16 items.
Duration: from 1/4 to a few seconds.
Structure: a separate sensory register for each sense
Biological basis: Sensory pathways

Q

details of Working memory

A

Function: Involved in control of attention attaches meaning to stimulation makes associations among ideas and events.
Encoding: Encodes information to make it acceptable for LTM
Storage capacity: 7±2 chunks
Duration: About 20 seconds unless repeatedly rehearsed
Structure: Central executive, Phonological loop, Sketchpad, Episodic buffer.
Biological basis: involves the hippopotamus and frontal lobes.

Q

details of Long-term memory

A

Function: Long-term storage of information
Encoding: Stores information in meaningful mental categories
Storage capacity: Unlimited
Duration: Unlimited
Structure: Procedural and declarative memory (further subdivided into semantic and episodic memory)
Biological basis: Involves various parts of the cerebral cortex.

Q

What is Long-term memory?

A

final stage of processing. stores information from working memory for long periods of time or forever. all the experiences, rules, skills, words. LTM contains total knowledge of the world and ourselves.

Q

Memory disorders

A

Amnesia - a failure of memory caused by physical injury, disease, drug use or psychological trauma

Anterograde amnesia - inability to form explicit memories for events that occur after the physical damadge to the brain.

Retrograde Amnesia - An inability to retrieve memories from the time before physical damage to the brain.

17
Q

Types of Memory

A

Sensory (<1sec)
Working (<1min)
Long-Term ( life-time)
/ \
Explicit (conscious) Implicit (unconscious)
| |
Declarative Procedural
(facts,events) (tasks,skills)
/ \
Episodic Semantic
experiences facts
events concepts

18
Q

What is Implicit memory

A

availability of information through memory process without conscious effort to encode or recover info. also known as UNCONSCIOUS or AUTOMATIC memory which is unintentionally memorized)

19
Q

What is Explicit Memory

A

Explicit memory is conscious effort to encode or recover information through memory process. it’s declarative memory because we consciously try to recall specific event or a piece of information.

20
Q

What are retrieval cues?

A

Retrieval cue- internally or externally generated stimulus available to help with rhetorical retrieval of memory. Elaborative rehearsal is a technique for improving memory by enriching rhetorical encoding of information.

21
Q

What is Primming?

A

Primming in the assessment of implicit memory, the advantage conferred by a prior exposure to a word or situation.

22
Q

What is Recall and Recognition?

A

Recall - a method of retrieval in which an individual is required to remember the information previously presented.

Recognition - a method of retrieval in which an individual is required to identify stimuli as having been experienced before.

23
Q

Context and Encoding

A

Encoding specificity principle - memories emerge most efficiently when the context of retrieval matches and the context of encoding.

24
Q

Mood and Memory

A

Our moods can affect what we remember, a phenomenon called mood-congruent memory. for example depression.

25
Q

What is Prospective Memory?

A

Prospective memory is a ability to remember to carry out intended actions in the future. remembering to remember. e.g going to lunch with a friend.

26
Q

Why do we forget?

A

Transience - Memories degrade with the passing of time. study was pioneered by German psychologist Herman Ebbinghaus

27
Q

What is interference?

A

3 main factors:
1) The more similar the two sets of material to be learned, the greater the likelihood of interference.

2) Meaningless material is more vulnerable to interference than meaningful material.

3) Emotional material can be especially powerful cause of interference.

28
Q

What is the Serial position effect?

A

Serial position effect - characteristic of a memory retrieval in which the recall of beginning and the end items on the list is better then recall of items in middle.
The primacy effect - refers to the relative ease of remembering the first items in the series.
The recency effects - refers to the strength of memory for most recent items.

29
Q

What is level of Processing?

A

A theory that suggests that the deeper the level which information was processed the more likely it is to be retained in the memory.

30
Q

The seven sins of memory

A

1️⃣Transience - decreasing accessibility of memory over time.
2️⃣Absent-mindedness - lapses of attention that result in forgetting.
3️⃣Misattribution - Memories are attributed to an incorrect source.
4️⃣Suggestibility - Implanted memories about the things that never occurred.
5️⃣Bias - Current knowledge and beliefs distort our memories of the past.
6️⃣Blocking - Information is present but temporarily accessible.
7️⃣Persistence - Unwanted recollections that we can never forget.

31
Q

What are Mnemonics?

A

Mnemonic strategies help us encode new information by associating it with long- term memory. 1) The method of loci (locations+items)
2) natural language mediators
