Examine one interaction between cognition and physiology in terms of behaviour. Evaluate 2 relevant studies Flashcards
What is cognitive neuroscience? What does it investigate? What has been the case in recent years? (3)
- the scientific study of biological correlates of mental processes (cognition)
- how various brain areas are involved in cognitive processes (e.g. how brain damage affects memory)
- researchers have also investigated how cognition and physiological processes may interact in people who meditate
What are a number of neuroscientists examining now? (2)
- how meditation or mindfulness-based stress reduction (MBSR) may influence brain functions
- the effect of meditation on attention, emotional reactivity and stress
Where can ‘interaction of cognition and physiology’ be seen? (1)
- in the self-regulation of attention (MBSR) which seems to have physiological benefits (stress reduction)
What are 2 relevant studies to examine one interaction between cognition and physiology in terms of behaviour? (2)

Aim: to investigate whether meditation can change brain activity
Method:
- eight monks who had practised meditation for many years and a control group of 10 students who had one week of training participated in the study
- cognitive activities (inc meditation) produce electrical activity why the neurons fire = recorded by the EEG (electroencephalograph which records electrical activity as brain waves)
- participants asked to meditate on ‘unconditional compassion’ i.e. open the mind for feelings of love and compassion for short periods
- control group participated in a training session where they were asked to think of someone they cared about and to let their mind be invaded by love and compassion
- after initial training the participants were asked to generate an objective feeling of compassion without focusing on anyone in particular
Findings:
- EEG of monks’ brains showed greater activation + better organisation + coordination of gamma waves = positive correlation between hours of practice and level of gamma waves
Conclusion:
- results support idea that attention and affective processes are skills that can be trained
Evaluation:
- but more research is needed to establish if the change in brain waves is caused by hours of training and not individual differences before training
What did Vestergaard-Poulsen et al. (2009) find? What were these things specifically? (2)
More (4)
- found that extensive practice of meditation involving sustained attention could lead to changes in brain structure
- structural changes in lower brain stem of participants engaged in LT practice of meditation compared with age-matched non-meditators
- MRI scans of two groups of participants = meditators + non-meditators
- study found changes in brainstem regions concerned with control of respiration and cardiac rhythm (autonomic nervous system) = connection of neurons seemed more complex in people who meditated = could explain some of the beneficial effects found in research on stress reduction techniques such as MBSR because cortisol levels are reduced and the cardiac and breathing rhythm slow down
- meditative practices have already been applied in health psychology e.g. Davidson et al. (2003) found that Mindfulness meditation could increase positive emotion and immune responses
- MBSR also found to alleviate pain (Grant et al. 2010)
