Practise IB Psychology SL 3.3.7 questions by evaluating how biological factors and chemical messengers influence personal relationships.
To what extent do biological factors influence human relationships?
Refer to the paper 2 assessment criteria when awarding marks.
The command term "to what extent" requires candidates to consider the contributions of biological factors in human relationships. Candidates may argue the extent of this influence by also addressing the influence of cognitive and/or sociocultural factors on human relationships. In addition cognitive and or sociocultural factors may be legitimately considered if they are shown to influence, or be influenced by, biological factors. However, answers should be supported with appropriate evidence and sound argument and the conclusion should clearly indicate the extent to which biological factors influence human relationships.
Responses may refer to evolutionary theories as well as physiological factors, such as hormones, neurotransmitters and the result of brain damage or brain disease. Evidence may be provided from any area of the option, for example:
- evolutionary explanations of pro-social behaviour and altruism
- hormonal influence on attraction, violence, trust and bonding
- Capgras' syndrome.
Candidates may consider a smaller number of biological factors and/or types of human relationships in order to demonstrate depth of knowledge, or may consider a larger number of biological factors and/or types of human relationships in order to demonstrate breadth of knowledge. Both approaches are equally acceptable. Marks should be awarded based on the quality of the consideration presented.
