Q

In Broca’s research, what one word could the patient say?

A

Tan

17
Q

What did Broca’s research show?

A

Language production is localised to one specific brain area

18
Q

Which hemisphere did EB have removed?

A

Left hemisphere

19
Q

What did EB manage to regain despite the loss of the left hemisphere?

A

Some of his language ability

20
Q

What is the problem with the use of case study?

A

Lacks population validity
Hard to generalise findings

21
Q

What has research found that contradicts that language is solely in the left hemisphere?

A

It may not always be in the left hemisphere. It may be in the dominant hemisphere

22
Q

What did Lashley find to contradict localisation of function?

A

No area of the brain was more important than any other in terms of rats learning’s a maze

23
