Understanding The Lateralisation Of Function In The Hemisphere

Question 1

Female

Answer 1

-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

Question 2

Males

Answer 2

• better at spatial skills (right hemisphere)
• (riled et ul. (2005)
  (Strengh) - men are better spatial awareness (weakness) - did notalways do belter on spatial awareness

Question 3

Sperry (1968)

Answer 3

Check studies!

Question 4

Laterisation of function

Answer 4

(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

Question 5

Asymmetrical function

Answer 5

(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)

Question 6

The left hemisphere

Answer 6

Processing language
Control of right hand
Right visual field
Speech
Understanding written language
Understanding what is heard
Logical thinking

Question 7

The right hemisphere

Answer 7

Spatial awareness

Control left hand
Left visual field
Creativity
Recognising faces
Musical ability

Question 8

The hemispheres

Answer 8

-They work together
-Primarily via the carpus callous one of the main bunches of library trying information between the hemispheres

Question 9

Kunal has damaged his left hemisphere. What tasks might kunal struggle with?

Answer 9

-Struggle with language ability’s
-Damage with logic ability’s
-Damage to analytical thinking

Question 10

Brocas area (left hemisphere)

Answer 10

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)

Question 11

Corpus callosum

Answer 11

(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

Question 12

Difference between males and females

Answer 12

Females supposedly like to: gossip, while males tend to do better at things like parking cars

Question 13

Strengths of lateralisation as an explanation of sex differences

Answer 13

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

Question 14

Weaknesses of lateralisation as explanation of sex differences

Answer 14

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
