Intelligence, Personality and Health (PSYL10101)

Aims and objectives:

  • to describe and evaluate research on the role that intelligence and personality traits may play in determining health across life.
  • to review research in the new field of cognitive epidemiology that shows that higher intelligence in youth is associated with a lower risk of premature death.
  • to consider evidence on various pathways through which higher intelligence might be linked to lower mortality, namely via socioeconomic advantage, improved disease or injury prevention, better disease or injury management, better mental health or ‘body system integrity’.
  • to evaluate research on the links between major personality traits and specific health outcomes and consider by what means personality might influence health.

Learning methods and resources

Each session will include a lecture but time will also be set aside for group discussion of issues raised in the lecture and course reading.  You may be asked to give a short presentation on a research paper during the session and will be expected to prepare one or two questions in response to other students’ presentations. A list of recommended reading for each lecture is given below.  

Tuesdays 11:10 - 13:00
Semester 1, Block 1
7 George Square, Room S.1
1
Introduction to cognitive epidemiology. Intelligence as a predictor of death
This session will introduce students to the field of cognitive epidemiology and to some basic concepts and methods of epidemiological research. We will consider the evidence that lower intelligence is a risk factor for earlier death and examine potential explanations for this link.
7 George Square, Room S.1
17/09/2018 - 2:10pm to 4:00pm
2
Intelligence and physical health
In this session we will consider whether intelligence is linked with specific somatic health outcomes and look at the evidence that intelligence might be a risk factor for unintentional injury. We will discuss potential mechanisms that might help to explain these associations.
7 George Square, Room S.1
24/09/2018 - 2:10pm to 4:00pm
3
Intelligence and mental health
In this session we will examine the evidence on the relationship between intelligence and various manifestations of mental distress, including diagnosed mental disorders, symptoms of anxiety and depression, attempted suicide, and somatization.
7 George Square, Room S.1
01/10/2018 - 2:10pm to 4:00pm
4
Personality, disease and mortality
In these sessions we will examine research on whether personality traits are linked to risk of death and other health outcomes (physical and mental) and explore the mechanisms that might underlie any associations.
7 George Square, Room S.1
08/10/2018 - 2:10pm to 4:00pm
5
Personality, disease and mortality
In these sessions we will examine research on whether personality traits are linked to risk of death and other health outcomes (physical and mental) and explore the mechanisms that might underlie any associations.
7 George Square, Room S.1
15/10/2018 - 2:10pm to 4:00pm
Learning Outcomes: 

By the end of the course students should be able to:

  • demonstrate understanding of some basic epidemiological concepts, such as causation and confounding.
  • describe and appraise evidence linking intelligence and risk of specific health outcomes.
  • describe and appraise evidence linking major personality traits and risk of specific health outcomes.
  • evaluate some hypothesised mechanisms underlying these findings, drawing on relevant evidence.
