Overview for test 1 Psychology DP24

The learning material for your first summative test in Psychology will be from the areas of biological psychology and research methodology (the experiment).

When revising for the test make sure to use your notes from lessons as what we do in class is directly relevant to the tests and the final exams.

Other material to use is the lesson powerpoints which can be found on google classroom as well as any other handouts or exercises that we have done. You will sometimes be asked to look at the Inthinking Psychology page during class activities and discussions, in that case the link will be provided to you on classroom.

Finally, I have provided the relevant pages in the Oxford textbook below so that you can revise at home.

The test will have two sections as per below:

| Section A: Biological psychology multiple choice questions biological content (5 points-1 per question) Practice questions | Section B: Research methodology (the experiment)
