Study Notes
Biological Approach
- Behaviour, cognition, and emotions are influenced by brain function, hormones, genetics, and evolution.
- Biological factors interacting with other influences shape similarities and differences between people.
Sleep and Dreaming
- Dement and Kleitman investigated biological processes of sleep and dreaming, specifically the REM (Rapid Eye Movement) stage.
- REM stage is strongly linked to dreaming, and waking from REM sleep often leads to more vivid dream reports.
- Sleep cycle comprises four stages: three NREM (non-rapid eye movement) and one REM.
- Laboratory experiment was conducted at the University of Chicago with 9 adult participants (7 male, 2 female).
- Variables: REM/NREM sleep, REM duration before waking, eye movement direction, number of dreams recalled, correct dream length estimations, and subjective dream reports.
Mindfulness and Brain Changes
- MBSR program led to structural brain changes in memory and emotion regions.
- Improved mindfulness correlated with increased grey matter.
Strengths and Weaknesses of the Study
- Strengths: Use of FFMQ, a highly reliable questionnaire, and a control group to improve validity.
- Weaknesses: Small sample size, lack of randomization, and self-selection of participants.
Ethics and Debates
- Ensured participant safety, informed consent, and the right to withdraw.
- Control group was offered MBSR after the study.
- Supports both nature and nurture perspectives.
- Highlights applications of mindfulness practices in reducing stress and improving well-being.
Hassett et al. Study
- Studied monkey toy preferences to explore the debate between nature and nurture influences.
- Findings could inform improvements in legal practices regarding children's testimonies.
Learning Approach
- Conditioning and social learning help explain changes in behaviour.
- Bandura et al. study: Children copy behaviour they see, even in new settings without the model present.
- Aim: Explore whether children copy aggressive behaviour when the person they observed isn't present, and if there are differences between boys and girls in learning aggression.
- Experimental design: Lab experiment at Stanford University's nursery school, with 72 children aged 3 to 6, evenly split by gender.
- Variables: Exposure to aggressive or non-aggressive models, and the model's gender; aggressive and non-aggressive behaviours observed in children.
