Q

Is Inattentional blindness in the eyes or brain?

A

In the brain.

Eye tracking can show where people are directing their eyes - People who didn’t see unexpected item looked at it as often as those who did!!!

Q

What is a conjunction search?

A
  • May be primitive features
  • When you are combining features together, to find those items you need to use your selective attention
  • Have to look around in a serial manner to find the bit that changed.

Q

What is the Feature Integration Theory?

A

Certain basic features are processed automatically (don’t have to think about it) and in parallel (process the entire visual field at once, not one object at a time)

Q

What is the cocktail party effect?

A

We can pay attention to one conversation in a noisy room, and seemingly “tune out” the others…except we’ll usually hear if someone says our name!

Q

What is the dot-probe task and what does it study?

A
  • Dots shown on left & right of screen, participants need to say which side, responses as fast as possible (speeded)
  • Before dot appears there are 2 images (one emotional, one neutral)
  • Most drawn to emotional image
  • Measures attentional bias

Q

What is attentional bias?

A

Bias toward emotionally threatening over neutral images in people with anxiety

(People with anxiety: faster to notice negative emotions (like anger or fear), slower to stop looking at them or shift attention away)

Q

What is encoding/recording?

A

The process of taking in information and converting it into a form the brain can store and later retrieve.
It’s the first step in creating a memory.

22
Q

What is storage?

A

The process of keeping encoded information in the brain over time, so it can be used later.

23
Q

What is retrieval?

A

The process of accessing and bringing stored information back into conscious awareness when you need it.

24
Q

Three stage model of memory (TSMOM) - Explain sensory memory

A

The first stage — where information from the environment enters through the senses (sight, sound, etc.)

A brief, high capacity, representation of what is being sensed:

  • Iconic: visual sensory memory (lasts about 1⁄4 of a second)
  • Echoic: auditory sensory memory (lasts about 2-4 seconds)
25
TSMOM - Explain working memory
A limited capacity system that temporarily stores and processes information Information will last about 20-30 seconds if not being used/actively processed
26
Examples of working memory
(Luck & Vogel, 1997) - show dots, take it away, is it in the same spot? Rehearsal helps keep information in working memory (repeating information to yourself)
27
What is Amnesia?
Amnesia is a memory disorder that involves partial or total loss of memory, typically caused by damage to the brain, trauma, or psychological factors.
28
TSMOM - Explain long term memory
Has no known capacity, transfers memory into long-term storage
29
Explain the primacy effect
Items that were made their way into long term memory store (first one on a list you are trying to remember usually
30
Explain therecency effect
Working memory, usually last words show on a list you are trying to remember
31
Explain the Serial position effect
People tend to remember the first and last items in a list better than the middle items.
32
What is explicit memory and an example
Requires conscious or intentional memory retrieval - Things you know, you know Example: Recalling the date of your friend's birthday.
33
What is declarative memory and an example
Factual knowledge and includes two subcategories: - episodic (personal experiences) - semantic (general factual knowledge) Example: Knowing that the Earth orbits the Sun.
34
What is implicit memory and an example
Influences our behaviour without conscious awareness. Example: Automatically feeling nervous when walking into an exam room, without consciously thinking about past experiences.
35
What is procedural memory and an example
Involves skills and actions and classically conditioned response Example: Riding a bicycle without needing to think about the movements.
36
What is a semantic network?
A semantic network is a structure of nodes and links where: - Nodes represent concepts or ideas (e.g., "dog," "animal," "pet"). - Links represent the relationships or associations between those concepts (e.g., "a dog is an animal").
37
Explain 'depth of processing' and give an example.
Using elaboration * “Is the word presented in uppercase letters?” * “Does the word rhyme with ‘cloud’?” * Information with personal meaning & distinctive properties are also better remembered. Example: if you live on 'plant' street you will likely remember it.
38
Explain 'Context-dependent memory' and give an example
Memory is improved when retrieval occurs in the same environment as encoding. Environmental cues present during learning can trigger memory during recall. Example: If you study in a library, you may recall the information better in the library.
39
Explain 'State-dependent & Mood -congruent recall' and give an example
Easier to recall information when your internal state or mood at retrieval matches that during learning. Examples: State: Being caffeinated or sober Mood: Sad mood leads to recalling sad memories Retrieval Cues: State, mood, and environment all help trigger related memories.
40
What is a 'Flashbulb memory' and an example
A vivid recollection of where you were and what you were doing when something emotional occurred; often high confidence in accuracy of memory Knowing exactly what you were doing when 9/11 happened.
41
Explain long-term potentiation
* Memories are formed by a series of biochemical events that occur between and within neurons: synaptic change. * Long-term potentiation (LTP): Enduring increase in synaptic strength
42
What is a hippocampus and what does it do?
Heavily involved in forming new memories Critical for spatial memory and navigation
43
Explain how parts of the brain are involved in long term memory Include: Cortex,
44
What is retrograde amnesia?
Memory loss for events that took place before the onset of amnesia.
45
What is anterograde amnesia?
Memory loss for events that occur after the initial onset of amnesia. Still have memories from before but cannot make or store new ones.
46
What is infantile amnesia?
Memory loss for early experiences. An exception is traumatic events (e.g. a car accident).
47
Who is Clive Wearing and what happened to him? What type of amnesia did he have?
A musician who contracted a type of herpes that severely damaged his brain. Retrograd and anterograde amnesia. - He can remember playing piano (procedural) & only remembers his wife and that he has kids. - He has an intact procedural memory but very compromised explicit memory.
48
Who is H.M (Henry Molaison) and what happened?
One of the most famous patients in the history of neuroscience and psychology - Suffered severe epilepsy, most of hippocampus & surrounding brain tissue removed. - Retrograd and anterograde amnesia. - His performance showed he was still able to store implicit, procedural memories (gain new procedural memories - learn new skills) EXPERIMENT - gave him task: shaped outline by 2 lines (close together) - he had to draw b/w lines not go over, look through a mirror. - did it over a no. of days, improving. - by 3rd day he forgot it again but made almost no errors. - a skill he has been able to learn even though having no memory of doing it before.
49
What is dementia?
Impaired memory and other cognitive deficits caused by brain degeneration that interfere with normal daily functioning.
50
What is Alzheimer’s disease?
A progressive brain disorder that is the most common cause of dementia.
51
What is Hyperthymestic Syndrome? Give an example.
A rare condition in which a person has an extraordinary ability to recall personal past events in vivid detail, often referred to as highly superior autobiographical memory (HSAM). Example: Jill Price - can remember every day of her life since she was 14 years old. - more episodic.
