Question 1

Comparing the two topographical tasks to the film tasks REVEALED?

Answer 1

the network of brain regions showing increased activation during semantic topographical memory retrieval are entirely different from those activated during retrieval of nontopographical semantic memory.

There was increased activation of the bilateral medial parietal regions, the posterior cingulate cortices,
during topographical relative to nontopographical memory retrieval.

Question 2

Ethics?

Answer 2

1. Pro - all participants gave consent for scans

2. Con - scans may be uncomfortable.

Question 3

Strengths?

Answer 3

1. Controls
   a. The sample consisted of all experienced taxi drivers

   c. This was a physiological study which implies the use of scientific equipment which is seen as reliable.
   d. The same machine was used throughout the experiment

Question 4

Validity?

Answer 4

the measure of rCBF (regional cerebral blood flow)allows them to make statistical inferences to compare results.

Question 5

Strengths about Reductionism?

Answer 5

Reductionist, that is it allows for simple explanations of a behavior. In this case the right hippocampus is involved in these type of topographical tasks.
