Change Detection Paradigm

Question 1

What is change detection paradigm?

Answer 1

• STM test that prevents chunking strategies via meaningful units
• It uses non-meaningful units to prevent chunking and linking information to existing memories

Question 2

What do the results of the CDP show?

Answer 2

True memory capacity = “amount of information” rather than number of items > few complex units of unconnected information may fill up as much capacity as many units of meaningful information

Question 3

Alvarez & Cavanagh 2004

Answer 3

• True STM capacity (without chunking) is likely around 4 for most people
• The more complex the items, the lower the performance
• Simple items are colour geometrical shapes, faces and animals are more complex

Question 4

What are the three units of the triangle model of the lexicon?

Answer 4

Orthographic
Phonological
Semantic

Question 5

How do we know that these representations are independent from each other? (3)

Answer 5

• You can read & understand a word without voicing it
• Tip of the tongue phenomenon
• You can say or hear a word without processing its meaning (but are able to recognise it)

Question 6

What is tip-of-the-tongue phenomenon?

Answer 6

When you know what you want to say but can’t remember the phonological structure automatically

Question 7

What are ERPs or EEG components?

Answer 7

Waves that regularly can be observed after a certain type of stimulus

Question 8

How are ERPs categorised? (4)

Answer 8

• Polarity
• Latency (how long after onset)
• Amplitude
• Topographic distribution
