16
Q

hierarchal organizations are a type of:

A

semantic network

17
Q

how to test semantic organization: (3)

A
  1. ask them directly
  2. look at the order of their recall (clustering)
  3. response time measurements, such as how quick they respond to a statement
18
Q

typicality effect:

A

finding that the more typical members of a category are classified more quickly than the less typical category

19
Q

spreading activation model:

A

accounts for response times by formulating assumptions about how activation spreads in a semantic network

20
Q

the spreading activation model can account for the:

A

typicality effect that the hierarchal model couldn’t

21
Q

when a concept is processed, activation spreads out along the paths of a network but its effectiveness:

A

decreased as it travels farther

22
Q

people in the Meyer study were ____ to responding to if the:

A

faster; strong of letters was a word if the response prior was related to it

23
Q

problem with spreading activation model:

A

it is not able to be falsified

24
Q

memory schema:

A

an organized cluster of knowledge about a object or event abstracted from pervious experience with the object or event

25
true or false:
a schema is a semantic network
26
aphasia:
loss of ability to understand of express speech caused by brain damage
27
brocas aphasia:
a language disorder that comes from damage in the frontal lobe with an inability to properly use grammar
