Study guide: Brain and behaviour

In order to prepare for exams, it is important to prepare a "tailor-made" study guide.  A study guide should reflect your own learning and not just what someone tells you is the "best" research to use on an exam.

For the topic "brain and behaviour", you will find an attached study guide.  I recommend that you attempt to fill it in before looking at the responses below.  There is both a paper and digital copy available.

Digital brain and behaviour study guide

Question 1: Discuss one or more techniques used to study the brain in relation to behaviour.

Terms/theories: MRI, fMRI, artifacts, PET.  For whichever technique you choose, you should be able to provide a basic explanation of how the technique works.

Research: Baumgartner et al (2008), HM: Milner (1966), Harris & Fiske (2006), LeVay (1991), Maguire (2000), Sharot et al (2007),  Raine on murderers, Cohen et al on resilience, Fisher on the "love cocktail" - any study can be used that uses brain technology.  Just be sure that you know which study uses which technology.

Critical thinking: Bennett et al's Dead Salmon study on the imprecise nature of fMRIs, the over-interpretation of colour coding, the issue of artifacts, the lack of ecological validity in studies, the problem that cost of running fMRIs often leads to small sample sizes, this technology allows for global researcher triangulation, use of databases is making it easier to obtain samples (eg. Maguire), lack of cause and effect.

Different command terms: SAQs:  Outline, describe and explain; ERQs:  Evaluate

Question 2: Discuss localization of behaviour.

Terms/theories: Localization, lateralization.

Research: HM: Milner (1966), Harris & Fiske (2006), LeVay (1991), Maguire (2000), Sharot et al (2007), Draganski (2004), Warrington and Shallice's study of KF (1970), The Case of Eugene Pauly 

Critical thinking: Localization research is often limited to very specific behaviours, for example, spatial memory, habits, etc. Memory as a whole is distributed throughout the brain.  Most of the research is of two types - animal research, in which direct manipulation of an IV can be carried out through lesioning - or correlational research, such as many of the quasi-experiments that are done.  Some of the studies above also are drawing indirect conclusions - e.g. Draganski and Maguire - about the specific role of certain areas of the brain.

Different command terms: SAQs:  Outline, describe and explain; ERQs: Evaluate research

Question 3: Discuss research on neuroplasticity.

Terms/theories: Plasticity, neural network, long-term potentiation, neural pruning, dendritic branching

Research: Maguire (2000), Draganski (2004), Rosenzweig, Bennet & Diamond (1972) 

Critical thinking: Neuroplasticity can be observed at multiple scales, from microscopic changes in individual neurons to larger-scale changes such as cortical remapping in response to injury. However, when it comes to studying the role of behaviour in the brain, it cannot be observed "live."  Research is generally correlational in nature; some research is also prospective in nature which allows the researcher to observe change over time; however, these studies are often low in internal validity as it is not possible to control for extraneous variables. Animal research tends to be more highly controlled, but this is difficult to generalize to humans. Although the physiological processes are the same, there are differences in the level of cognitive complexity between people and animals.

Different command terms: SAQs:  Outline, describe and explain; ERQs: Evaluate

Question 4: Discuss neurotransmitters and their effect on behaviour.

Terms/theories: Memory consolidation, acetylcholine, antagonist (scopolamine)

Research: Acetylcholine: Antonova (2011), Rogers & Kesner (2003), Troster and Beatty (1989); research on serotonin and depression may be used as well - for example, Rausch et al (1985), Moreno and Delgado (2000), Ansorge et al (2004)

Critical thinking: Attributing complex human behaviours to neurotransmitters is reductionist, this approach has, however, led to drug treatments. Research on animals may not be generalized to humans, but there are clear similarities in the physiological processes.  There are ethical concerns with some of the research. Studies may lack ecological validity, not showing how the neurotransmitter functions in normal human behaviour.

Different command terms: SAQs:  Outline, describe and explain; ERQs: Evaluate research

Question 5: Discuss ethical considerations in the study of the brain and behaviour.

Terms/theories: You should be able to "unpack" each of the ethical considerations that you discuss - e.g. what does "informed consent" mean?

Research:  Any of the studies above could be used to answer this question.

Critical thinking: The complexities of informed consent in the study of HM, the use of animals in research ( Rogers and Kesner); Undue stress or harm ( Rosenzweig et al), the importance of anonymity in HM or KF's case study.

Different command terms: SAQs:  Outline, describe and explain; ERQs: No other command terms may be used.

Question 6: Discuss the use of one or more research methods in the study of the brain and behaviour.

Terms/theories: You should be able to define any research methods that you choose: experiments, observations, interviews, questionnaires or case studies.

Research: Case studies ( HM, KF), experiments ( Rogers and Kesner, Draganski, Maguire, Troster and Beatty)

Critical thinking: Causality; the problems of artificiality and ecological validity; the importance of replication, internal validity and construct validity (aka face validity).

Different command terms: SAQs:  Outline, describe and explain; ERQs: Evaluate, contrast

The following questions will only be asked on the 2020 exam and later - and will only be asked as SAQs.

Explain the role of inhibitory or excitatory synapses in one behaviour.

Terms/theories: Excitatory and inhibitory synapses.

Research:  Studies of inhibitory synapses include studies of serotonin or GABA: Prevot et al (2019), Serotonin hypothesis (1967). Studies of excitatory synapses include studies of dopamine, acetylcholine, or norepinephrine: Rogers & Kesner (2003), Antonova (2011), Troster and Beatty (1989).

Different command terms: Outline, describe, explain. This question may not be asked as an essay question
