PAPER 2026 FULL SOLUTION VERIFIED PASS
◉ Split-brain studies. Answer: Corpus callosum cut in patients with
severe epilepsy, allowing researchers to investigate the extent to
which brain function is lateralised.
◉ Describing what you see. Answer: Pictures shown to RVF could be
described but not those to LVF because no language centres in left
hemisphere (connected to RVF).
◉ Recognition by touch.. Answer: Could not describe objects
projected to LVF, but able to select a matching object from a selection
of different objects using their left hand.
◉ fMRI. Answer: Measures brain activity in specific areas by
detecting associated changes in blood flow.
◉ EEG. Answer: A record of the brain wave patterns produced by
millions of neurons, producing characteristic patterns.
◉ ERPs. Answer: Isolating specific responses of neurons to specific
stimuli or tasks.
, ◉ Post mortem examinations. Answer: Correlating behaviours
before death with brain structures after death.
◉ Circadian rhythms.. Answer: Have cycles that generally occur once
every 24hrs.
◉ Infradian rhythms. Answer: Have cycles that occur less than once
every day.
◉ Ultradian rhythms. Answer: Have cycles that occur more than
once every 24 hours.
◉ Biological rhythm. Answer: Distinct patterns of changes in
biological activity that conform to cyclical time periods.
◉ Siffre study. Answer: spent extended periods underground.
Deprived of exposure to natural light and sound, but with access to
adequate food and drink. His biological rhythm settled down to one
that was just beyond the usual 24 hours.
◉ Aschoff and Wever. Answer: Participants spent 4 weeks in a WWII
bunker deprived of natural light. All but one of the participants
displayed a circadian rhythm between 24 and 25 hours.
