1 mark per correct point.
The experimenter/police officer might be seen as an
authority figure.
This makes the child feel intimidated/nervous/stressed.
The child chooses to not get into trouble.
The child might want to ‘please’ the experimenter/police
officer so chooses anyway.
It could be social pressure affecting identification in line-ups
(rather than cognitive).
The mere presentation of a line-up from an adult might make
the child feel like a choice has to be made.
Not selecting might indicate that the child is not willing to
take part and therefore a wrong choice is made.
The child might guess who the experimenter/police officer
thinks is the culprit and choose them.

watching a line-up and having to identify a cartoon character
is not stressful (1 mark: explanation). Also, the children were
already familiar with Dora/Diego so seeing these faces
amongst others would not be seen as psychologically
stressful (1 mark: explanation).
e.g., Tony
The children might have felt some psychological stress in
the target-absent line-up (1 mark: identification). This is
because we know that social pressures can impact on
children, and they may have chosen under cognitive stress
(1 mark: explanation). It can also be argued that there was
no right to withdraw (1 mark: guideline) as participants were
questioned by an adult and they may have felt like they had
to answer (1 mark: explanation).
There are other creditworthy arguments.

Overall, the ill victim was helped more than the drunk victim.

the study or knowledge of mechanisms of technique (e.g.,
mindfulness, meditation).
1 mark for partial/brief reason.
e.g., 2 marks
One result from the study showed that engaging in
mindfulness increased ‘observing’ behaviour so Pavel can
identify and control stressors at work, therefore, reducing
stress.
Meditation allows Pavel to focus on one thing at a time
allowing him to reconnect/make time for himself and not let
work dominate.
There was an increase in grey matter in the MBSR group in
areas that could control stress/emotion.

In the study by Hölzel, the effects of mindfulness were seen

There was an increase in grey matter in the MBSR group.
Meditation helps to clear stressful thoughts.

10 Evaluate the study by Bandura et al. (aggression) in 10
terms of two strengths and two weaknesses.
At least one of your evaluation points must be about
ethics.
Strengths include reliability (standardisation), quantitative
data, validity.
Weaknesses include ecological validity, ethics,
generalisability, quantitative data.
Example: in detail
The study collected quantitative data which makes it easier
to make meaningful comparisons between
groups/conditions. They measured things like number of
times a physical/verbal aggression was imitated. This meant
there could be a direct comparison between
aggressive/nonaggressive models or male/female models.
Example: brief but in context (named issue)
The children may have been psychologically
harmed/stressed by watching an adult beat up a Bobo doll in
front of them.
Example: no context
There was a standardised procedure meaning it could be
replicated/tested for reliability.
