1.1 Outline principles that define BLOA
and explain how these principles may
be demonstrated in research
#1 There are biological
correlates of behaviour
Annotations:
- The works of neurotransmitters, hormones, specialised brain areas and genes
- REDUCTIONIST APPROACH
Newcomer et al (1999)
Annotations:
Aim: investigate how corisol levels interfere with verbal declarative memory (VDM)
Procedure:
- 51 normal and healthy individuals (recruited through ads) aged 18-30
- randomised, double blind, controlled, 4 days
- consent
- three groups: 1 = 160 mg of cortisol, 2 = 40 mg, 3 = placebo
Results: high level of cortisol group = worse on VDM, low level group (mild stress) no memory decrease
#2 Animal research can provide
insight into human behaviour
Rosenzweig and Bennett (1972)
#3 Human behaviour is, to some
extent genetically based
Bouchard et al (1990)
1.2 Localization of function in the
brain
Case study: Henry Mollaison
Milner (1957)
Corkin et al (1997)
1.3 Explain, using one or more examples, the
effects of neurotransmission on human
behaviour
Example #1 Dopamine
Fisher et al (2003)
Example #2 Acetylcholine
Martinez and Kesner (1991)
1.4 Explain using examples, the
function of two hormones on human
behaviour
Example #1 Cortisol and memory
Newcomer et al (1999)
Example #2 Oxytocin and trust
Baumgartner et al (2008)
1.5 Discuss two effects of the
environment on physiological processes
Effect #1 dendritic branching
(brain plasticity)
Rosenzweig and Bennett (1972)
Effect #2 environmental stressors
and hippocampal damage in PTSD
patients
Bremner et al (2003)
1.6 Examine one interaction between
cognition and physiology in terms of
behaviour (and evaluate)
Attention and physiology (MBSR)
Davidson et al (2004)
Vesterfaard-Poulsen et al (2009)
Case Study: Clive Wearing - Sacks (2007)
Case Study: HM - Scoville and Milner (1957)
1.7 Brain imaging technologies in
investigating the relationship between
biological factors and behaviour
MRI Scan
Maguire et al (2000)
fMRI scan
Harris and Fiske (2006)
1.8 Which genetic inheritance
influence human behaviour
Gene mapping
Caspi et al (2003)
Twin studies
Bouchard et al (1990)
1.9 Examine one evolutionary
explanation of behaviour
Disgust in pregnant women
Fessler et al (2005)
1.10 Ethical considerations in research
into genetic influences on behaviour
1.11 Discuss how and why particular
research methods are used at the BLOA
