Major differences between Broadbent and Triesman's models
1. Broadbent suggests that there is an attentional filter very early in the processing stream, which filters out stimuli based on physical characteristics. Treisman suggests that there is an attenuator that gives processing preference to stimulus based on what we are trying to do at the moment. Each stimulus has a different activation threshold. Attention is goal directed . Broadbent suggests that the filter blocks out all unattended stimuli. The unattended stimuli do not receive any processing if attentional capacity is overloaded. Treisman suggests that the attenuator does not block out processing, it simply gives preference to the attended stimuli. If there is enough cognitive resources, the unattended stimuli can get processed, too.

War of the Ghosts
- 20 participants read the story twice - Tested recall after several minutes, weeks, months and years - Story became SHORTENED, phrases reflected modern concepts and the story became more COHERENT - Transformations were reported to make the story more familiar
STM summary
- Acoustic and verbal encoding - Duration 15 - 30 seconds - Storage capacity 5 - 9 items - Forgetting by decay through displacement - Retrieval by sequential search
Weaknesses of WMM
- Artificial task, lack ecological and task validity - Only explains STM, not transfer to LTM - Central Executive is simplistic and vague, doesn't explain what it does, difficult to design tasks to test it
Weaknesses of episodic/ semantic memory
- Clive Wearing suffered memory impairments that affected LTM recall from episodic storage but he was still able to perform procedural tasks. Suggests a further long-term store for remembering practised skills - Difficult to test as they both work together, so research into separate stores is problematic because they cannot be isolated
How does the concept of the WMM help with understanding dementia?
- Different tasks done at the same time using the same type of processing can be difficult - Avoid such tasks - Use one store at a time
Weaknesses of reconstructive memory
- Does not deal with the process, it is a description rather than an explanation - War of the Ghosts is an unusual story that does not make sense, so it could be argued that there could be demand characteristics where the participants guess what is intended - WMM and MSM
How were the words presented in Baddeley's experiment?
- Each list of 10 words was presented by slide projector - Correct order one at a time for 3 seconds and two second slide changeover

LTM summary
- Semantic encoding - Potentially a lifetime of duration - Limitless capacity - Forgetting through decay and interference - Semantic retrieval
Strengths of MSM
- Supporting evidence - HM case study gives physiological support - Shows they have separate stores - Baddeley conducted an experiment and found that semantic words were more difficult to recall, suggests encoding in STM and LTM were different

implicit memory
- influenced by prior experience on behavior w/o an attempt to remember - expressed by an increase in speed / increased probability of a response.
How does the concept of STM help with understanding dementia?
- may forget what they have been told because memory was not encoded - could ask very specific questions rather than general questions - using pictures and colours can help encoding memories, labelling
Issues and debates - nature/ nurture
- nature= HM and brain function - nurture = reconstructive memory emphasises experiences
types of pictures for experiment
- neutral - negative - scramble
Is the emotion-induced blink an automatic effect? (Can we control it?)
- not completely - attention capture by emotional stimuli can be reduced when resources are limited - however, those subject had knowledge about the task

multiple-factor approach
seeking to describe how concepts are represented in the brain by searching for multiple factors that determine how concepts are divided up within a category
In semantic memory tasks, response time is speeded up or judgements are made more easily when the concepts are closer together in semantic distance-that is, when they are more closely related. The effect is reversed when the comparison is false; that is, RT is longer for the comparison "a whale is a fish" vs. "a whale is a bird." This is an example of
semantic relatedness effect
Category specific deficits in object recognition provide support for the existence of the following stage in object recognition
semantic system
What is the purpose of iconic memory?
serves as a buffer (brief storage) for visual processes
Donald MacKay experiment (messages are processed at a later stage of processing based primarily on their meaning)
shadowed ambiguous sentence in attended ear and biased word was played in unattended ear. Attended ear "They were throwing stones at a bank" Unattended ear: "River" or "Bank" Subjects then had to pick a sentence that most matched what they heard, Based on the biased word heard, subjects chose that sentence
Ch. 4 A different audio message is played to each ear. The task is to repeat back the message as soon as it is heard. This task is most commonly called
shadowing

testing slows down forgetting, and its benefits persist over time
attention
the act or power of carefully thinking about, listening to, or watching someone or something
recollection
the action or faculty of remembering something.
priming effect

Ebbinghaus forgetting curve
the course of forgetting is initially rapid, then levels off with time
learning phase continued
the d subscript is the ones that you drop (such as is you know five then those five you will be dropped the next time you study the cards again) this is repeated test only condition repeated study only condition, you will then study all items in all study cycles. for the test you will drop only the ones that you know, so in test one you got 6 out of 20 right and then the rest cycle you only take a test out of 14 and so on. Won't be retested on it, but will study it. Flash card method: you have 20 in the beginning, you then do the testing phase and get 6 right then the next study session you only study 14 cards and so on..
Ch. 3 Sensation is

What is the finding that memory is better when people actually do something?
the enactment effect
Someone tells you about an event she experienced. Later, you try to remember just what was said. According to research, such as that by Sachs (1967), you are most likely to recall
the general gist of what was said, but not the exact wording

persistence
the tendency to remember facts or events, including traumatic memories, that one would rather forget, that is, failure to forget because of intrusive recollections and rumination
Modal Model
the three-stage memory model that divides memory into 3 areas--sensory, short term, and long term
Topographic map
their is a spatial map of visual stimuli on the visual cortex Each point on a visual stimulus causes activity at a specific location on the visual cortex. This is just passivly looking. However if they kepp looking at the spots on a disc but shift their attention, what happens? Attention enhances activity on the locations of the tomographic map where they are paying attention. "this is the brains way of "taking possesion" Based on this they could create attention maps for subjects and then have them direct attention to a secret spots and researches could know where that spot was based on brian activity! Also did this with moving images of houses and faces
Why was there no testing effect after 21 days
their performances has already bottomed out. All the forgetting has already happened by 21st day. Testing only provides benefits when you take an initial test as soon as possible.

yes, emotion can induce attentional blink (when the lag between distractor and target is short)
What are two (of the three) important factors that contributed to the cognitive revolution?
» A need for practical understanding of mental phenomena » A growing dissatisfaction with behaviorist explanations » Slow accumulating changes in nature of verbal learning research
You have a friend who literally can't walk and talk at the same time; they have no ability to multitask. Bumps into things, falls over. Which approach to attention works best for thinking about this problem?
» Capacity theories (mental resources, cognitive fuel)
The Corteen & Wood experiment that examined how people's galvanic skin response changed as a function of the types of words (shock-associated cities, other cities, random words) read in the unattended channel is a problem for early filter theories of attention. Why can't the early filter theory explain this finding?
» Early filter is based solely on physical characteristics, so the unattended words should not have been processed for meaning. The GSR indicates that they were processed for meaning.
