Localisation, lateralisation & plasticity

The brain contains four lobes.

Briefly describe each of these structures and their basic function.

What is the median for the total anxiety scores for 30 days?

The following scatter diagram also shows the results found by the neuroscientist.

The possible locations of two of the participants’ results are shown by the letters A–F.

Identify the correct locations on the scatter diagram for the results of participant 002 and participant 010.

Shade two boxes.

Name the type of correlation the neuroscientist has found between language difficulties and anxiety levels.

When the neuroscientist saw the results, she claimed to have found the cause of anxiety in people who have had a stroke.

Explain why the results do not show that language difficulties cause anxiety.

Outline how neurological damage from a stroke or injury can affect motor abilities and behaviour.

Refer to localisation of function in the brain in your answer.

Read the following descriptions of two structures of the brain.

Write the correct letter A, B, C, D or E in the box next to each description.

A Cerebellum

B Frontal lobe

C Occipital lobe

D Parietal lobe

E Temporal lobe

Read the following information.

From the information, identify two examples of situations where the parietal lobe was involved and identify two examples of situations where the occipital lobe was involved.

Write your answers in the correct boxes.

This outline of the brain shows the temporal lobe. This is one of four lobes in the brain.

On the outline, sketch the location of the three other lobes. Label these three lobes and the cerebellum.

Briefly describe Penfield’s study of the interpretive cortex.

Evaluate Penfield’s study of the interpretive cortex.

A psychologist researched treatment for stroke patients with damage to the language areas of their brains. She compared the effectiveness of two kinds of speech and language therapy. One therapy was carried out in person by a trained therapist. The other therapy was carried out by a specially programmed computer known as a virtual therapist.

The psychologist timed each participant reading the same paragraph of text before and after six weeks of speech and language therapy. She then worked out how much faster the participants could read the text at the end of the six weeks. The results are shown in Table 1.

Table 1: The decrease in time taken to read a paragraph of text after six weeks of speech and language therapy.

Name one of the lobes of the brain where a language area is located.

What is the mode for the decrease in time taken when the speech and language therapy was provided by the trained therapist?

Calculate the range for the decrease in time taken when the speech and language therapy was provided by the virtual therapist.

What percentage of the twenty participants were able to read the text more than 40 seconds faster after six weeks of therapy?

Describe Penfield’s case study of the interpretive cortex.

Evaluate the research method used in this study.

A neuropsychologist is trying to find out why a patient is suddenly experiencing difficulties moving one side of their body.

Use your knowledge of psychology to:

name which lobe of the brain the neuropsychologist should investigate and explain your answer

suggest a possible cause of the neurological damage that the patient seems to be experiencing.

Lobe of the brain and explanation

Name an appropriate scanning technique that the neuropsychologist could use as part of his investigation. Justify your answer.
