Q

What are the conclusions about MossTalk for NPPA?

A
  • both patients benefitted (to diff degrees) from a computer based treatment for anomia
  • effectiveness of treatment for anomia in NPPA comparable or better to post-stroke anomia (looking at maintenance)

Q

In the treatment of anomia in SPPA, what were the methods of tx?

A

Q

Explain what happened to the words on the control list (words she could comprehend and name but that she wasn’t trained on).

A

-There was a decrease in naming accuracy of words she knew at the start (~25% decrease)

Q

What happened to AK’s naming accuracy scores to words that she could understand and name and that were targeted during treatment?

A

They remained at 100%, indicating that treatment of known words can help prevent loss of words in PPA.

Q

Based on the results from AK’s treatment for SPPA, is it better to work on words that a patient knows but can’t name or words a patient doesn’t understand and can’t name

A
  • words they understand but can’t name
  • you only have to help them relearn the word, compared to teaching comprehension and the name
  • this group of words had higher naming accuracy for AK compared to words she couldn’t understand or name

Q

What 3 factors affect success in therapy of word naming?

A
  • personal familiarity with items (linked to patients autobiographical experience) affects remembering
  • organizing words into semantic categories is more helpful than organizing them alphabetically
  • partially spared semantic knowledge facilitates relearning

Q

Describe what the procedure for errorless learning is in semantic dementia

A

look at the object and tell me its name only if you are 100% sure you are correct. Otherwise listen to the description nada read the written word

17
Q

How was the MossTalk program used with SPPA?

A
  • each picture presented on the screen, accompanied with a written and spoken description
  • the correct name would be displayed after each trial regardless of the outcome
18
Q

In the MossTalk experiment with CST who had SPPA, what were the results on the 3 lists?

A
  • significant improvement post-tx
  • effects maintained 1 month post
  • effects maintained 3 months post
19
Q

T or F: CST (SvPPA) was able to name 100% of the +N+C control words after 4 months of treatment

A

FALSE: his naming accuracy of the control words decreased by 50% as they were not treated

20
Q

What are the theoretical implications of CSTs evidence from computer based errorless retraining of words in SvPPA?

A
  • feasibility of computer-based treatments for anomia in SvPPA established
  • effectiveness of errorless approach in SvPPA in re-teaching lost words
  • justification for including in tx the words that patients with SvPPA still have in their vocal
21
Q

Summarize the positive aspects of errorless learnign

A
  • effective therapeutic technique
  • successfully been applied to anomia in SvPPA
  • effective for people with reduced explicit memory
22
Q

What are some positives of effortful processing

A
  • subject generated (effortful, elaborative) info retained better
  • effortful learning improves recollection
  • Effortful processing may facilitate learning in SvPPA?
23
Q

Explain passive errorful learning

A
  • Experimenter provides a list of things that don’t apply to the certain animal
  • Then asks patient to name the animal
  • Asks them to repeat the correct name (whether they were correct or not)
24
Q

Explain active errorful learning

A
  • Experimenter asks many questions about an animal, which patient has to answer
  • Then asks patient to name the animal
  • Asks them to repeat the correct name (whether they were correct or not)
25
Q

Explain passive errorless learning

A
  • experimenter lists characteristics of an animal (semantic and phonological)
  • experimenter provides name
  • patient repeats name
26
Q

Explain active errorless learning

A
  • experimenter asks questions about the animal (semantic and phonological) to which the answer is always YES
  • experimenter asks “Is it called (correct response)”
  • patient repeats name
27
Q

Subject generated cues involves _____ learning

A

active

28
Q

Experimented provided cues involves _______ learning

A

passive

29
Q

In a true errorful approach, there needs to be _____ wrong answers

A

2-3

30
Q

What type of approach was most effective on word re-learning for individuals with SvPPA?

A

errorless active (subject generated)

31
Q

T or F: errorless active learning also had the best effect on post-tx word comprehension

A

False - no significance between all 4 learning methods and word comp

32
Q

Semantic processing is thought to originate the ___________ in the brain

A

anterior temporal lobe

33
Q

What changes in brain activation may occur as a result of naming tx for SPPA?

A

-increased activity of activation in anterior temporal lobe (occurred only in least impaired participant)

34
Q

What things do you need to remember when providing language tx in SvPPA?

A
  • greater success with personally relevant items
  • semantically based treatment more successful
  • clients involved in item selection
  • more effective with partially spared semantics
  • practice necessary to maintain gains
  • incorporate re-trained vocal into daily language
  • computer based tx is appropriate
  • errorless approach > traditional errorful approach
  • self-generated cues > experiment-provided cues
35
Q

What are the overall benefits of language tx in PPA?

A
  • improvement in naming
  • focused activity
  • possibility of re-learnign words necessary for daily functioning
  • possible generalization to different items and contexts
  • maintenance of gains with practice
  • neuroplasticity?
