2 psychologists who criticised EPs and EZs - Answer-Damiola
Miles
/.4 common neurotransmitters - Answer-- Acetylcholine
- Noradrenaline
- Dopamine
- Serotonin
/.Acetylcholine - Answer-Stimulates muscle contractions...
/.Acetylcholine - Answer-Stimulates muscle contractions, key function in motor control
and movement. Memory, attention and alertness. Expressions of anger and sexuality.
/.Amygdala - Answer-- Limbic system
- Self-preservation, flight/fight response
- Centre for emotions and motivation
- Combines all sensory modality to give an instinctive feeling or reaction
- Identifying threat
/.Amygdala (Raine) - Answer-Associated with aggressive behaviour. Reduced activity
associated with fearlessness
/.Animal studies involving amygdala - Answer-If amygdala is stimulated using electrical
current, the animal shows aggression. If amygdala is removed, animal becomes passive
and unresponsive and doesn't respond to fear.
/.Apparatus in your practical - Answer-- Questionnaires
- Brief and debrief
- Pen
- Stopwatch
- Standardised procedures
/.Aschoff and Weber - Answer-Ps in bunker changed sleep wake cycle to 25-27 hours.
/.Beeman (1947) Castrated male mice - Answer-Castrated male mice had reduced
aggression. Later, injected the mice with testosterone which re-established aggression.
/.circadian rhythms - Answer-bodily rhythms that last around 24 hours
/.Closed question in your practical - Answer-In general, would you say that you are a
stressed or relaxed person?
Stressed / relaxed
,/.Conclusion in your practical - Answer-Raw data shows there is a relationship between
stress and aggression, but statistical test shows no significance. Does not support
previous data.
/.Concorance rate - Answer-The extent to which the same behaviour is the same
between twins. An agreement rate when both twins have got a characteristic.
/.Controlled variables in your practical - Answer-- Same questionnaire with same
questions
- Done at the same time in the same place
- 5 minutes to complete the questionnaire
/.Corpus callosum - Answer-Section that joins the two hemispheres
/.Corpus callosum dysfunction (Raine) - Answer-Associated with predisposition to
violence.
/.Correlations - Answer-A way of looking at relationships between two variables, not
causes. If two variables are correlated, you can predict one from the other.
/.Cortex - Answer-Outer layer of the brain
/.Dabbs (1987) testosterone in the saliva of 89 male prisoners - Answer-- Measured
levels of testosterone in the saliva of 89 male prisoners involved in violent/ non-violent
crime
- Level of testosterone was higher in those who had been involved in violent crimes
- Higher levels of testosterone were also rated by peers as being tough (correlational)
/.Damiola criticised EPs and EZs - Answer-Influences other than SCN affect sleep wake
cycle. Changing feeding patterns of mice altered circadian rhythms of liver cells by 12
hours whilst SCN unaffected
/.Decoursey's research of SCN - Answer-Destroyed the SCN connections in a chipmunk
which removed the sleep wake cycle and caused large proportion to be killed by
predators
/.Define: Dizygotic - Answer-Twins that come from two separate zygotes (fertilised
eggs) so share only 50% of DNA, just like a normal brother and sister.
/.Define: Gene - Answer-A piece of DNA that codes for a specific characteristic.
/.Define: Hormone - Answer-A (usually slower, but long term) chemical messenger
which is transported in the bloodstream to trigger and regulate certain processes.
EG Testosterone, Cortisol, Oestrogen, Androgens.
Secreted by the endocrine system.
, /.Define: Monozygotic - Answer-Twins that come from the same zygote (fertilised egg),
so share 100% of DNA.
/.Define: Neurotransmitters - Answer-A chemical that is stored in the axon terminal in
vesicles, and is transmitted across the synaptic cleft, transferring messages from
neuron to neuron.
EG Serotonin, Dopamine, GABA.
/.Define: Synapse - Answer-A junction between two neurons, where impulses are
passed along by neurotransmitters.
/.Describe Brendgan et al. (2005) - Answer-Twin Study
Aims:
To see if social aggression is genetic or environmental.
To see if physical aggression is genetic or environmental.
To see if one type of aggression leads to another.
Procedure:
234 pairs of MZ/DZ, M/F/Mix twins from Quebec, Canada. Longitudinal study that
continued until twins were 6 years old. Teachers rated twins on preschool behaviour
scale and indirect aggression scale. Peers identified classmates with certain attributes,
eg 'Gets into lots of fights'.
Results:
Link between both type of aggression.
MZ twins had a higher levels of physical aggression than DZ twins, suggesting physical
aggression is genetic.
MZ and DZ twins had similar levels of aggression suggesting social aggression is
environmental.
Conclusion:
Physical has a strong genetic component.
Social has a strong environmental component.
Physical aggression leads to social aggression as genes interact with the environment.
/.Describe CAT scans. - Answer-Computerised Axial Tomography.
X-rays used to create a detailed image of brain sructure, which can be layered together
to produce a 3D image.
Used to detect infraction, tumour, haemorrhage and trauma etc.
/.Describe fMRI scans. - Answer-Functional Magnetic Resonance Imaging.
A magnetic field causes oxygen in the brain to align, and the oxygen is shown on a
computer screen as 'voxels'. More active areas have more oxygenated haemoglobin for
respiring tissues.
Used to detect diseased tissue, monitor tumours and observe brain function.
/.Describe PET scans. - Answer-Positron Emission Tomography.
