Q

Female

A

-better at language skills (left hemisphere)

  • harasty et al (1997) (strengh) - parts of the brain process, produce language are bigger in female - view females better at tasks and use language (weakness) - no strong evidencefemales use both hemispheresfor language tasks

Males

A
  • better at spatial skills (right hemisphere)
  • (riled et ul. (2005)

Q

Laterisation of function

A

(The different jobs that are done by each half of the brain;each hemispheres will have different specialties roles that it performs)

-Idea that two hemisphere of the brain divide specilasim of function
- are not identical
- right br = left Bo
- left br = right bo

Q

Asymmetrical function

A

(Two hemispheres are not equal in terms of what they do)

Difference between two sides of the brain make it asymmetrical (they are not mirror images of themselves)
-The right hemisphere, controls the left side ofthe body
-The left hemisphere controls the right Side of the body
(Corpus callousness helps the hemispheres work together, connects the right and left hemispheres)

Q

Brocas area (left hemisphere)

A

Controls the production of speech
Broca’s area is linked to the control of the nerve cell in the face that help us speak

If damaged problems may be:
-process language based information
-speech fluency ability (struggling to talk)

Q

Corpus callosum

A

(A thick bundle of nerve fibres connecting the two hemispheres of the brain so they can communicate with each other)

Makes it easier to pass messages between the different areas of the brain
Connects right and left together
Allows two sides of the brain to communicate
This allows the whole brain to work as one organ

Q

Strengths of lateralisation as an explanation of sex differences

A

Some studies provided evidence
- Harasty eat al (1997) (females left hemisphere) suggested parts of the brain that produces and processes language are slightly bigger in females then males
-Rilea eat al (2005)(males right hemisphere) found males were better at some special tasks, especially those that use a lot of activity in right hemisphere
Lots of evidence to support difference
-brain scans, lab experiments (scientific methods)
- research is well controlled and evidence is scientific

Q

Weaknesses of lateralisation as explanation of sex differences

A

Some of the research evidence has weaknesses
-rilea el al (2005) males did not always do better in spatial tasks
- few spatial tasks didn’t use the ‘right brain’ activity
Study by Sommer et al (2004)
-females used both hemispheres for language tasks
-not good explanation for girls being better at language skills then boys
