Mark scheme

Marking points from the official mark scheme (Oct/Nov 2019). The mark or mark type is shown in brackets.

[1] 1 mark for correct answer. Keeping the situation/procedure the same for all participants = 1 mark Making sure that each person is treated the same way except for the IV = 1 mark Keeping everything the same = 0 marks Reducing differences between the levels of the IV = 0 marks
[3] 1 mark per correct standardised feature relating to the lab to max 3 marks. Standardisation before arriving at the lab is irrelevant. Same fitting of electrical equipment: ∞ Electrodes near eyes ∞ Electrodes on scalp ∞ Wires gathered into 'pony tail' Participants in bed Quiet room Dark room Woken by doorbell There was a voice recorder
