Planning your course effectively – the biological approach and development

Overlaps Dev_Bio green

The biological approach to children’s cognitive development is well-established, as it seems obvious that learning must be directly related to neurogenesis (growth of new synapses connecting neurons) and neural pruning (‘cutting back’ of synapses no longer needed).  But of course this development through neuroplasticity requires not only good nutrition and nurturing to prevent injury, but also social stimulation, so a lot of research has looked at how trauma and deprivation may affect the cognitive development of the child, by delaying or preventing brain development in crucial areas like the hippocampus and amygdala.

The techniques used to study the brain and neuroplasticity topics under the biological approach can be successfully taught using material from the developing as a learner and the influences on social and cognitive development topics within the developmental psychology option. Recommended studies are Chugani’s (1998) PET scans of children from birth to late adolescence; Gotgay et al’s (2004) longitudinal study mapping brain development using MRI scanning; Luby et al’s (2013) research into the effects of poverty on the brain and the mediating effect of caregiving.

More help with planning is coming in the following weeks!

Planning your course effectively – the sociocultural approach and health


The sociocultural approach is increasingly used in health psychology, as it became obvious that not all disorders could be explained through a biological etiology.  For example, addiction can be caused and sustained through our position in social groups, and treated through the support of social networks. Pegg et al. (2018) conducted a survey that investigated social identity and alcohol use in teens and found that higher levels of exposure to alcohol-related content on social networking sites was associated with higher levels of alcohol use, as the online social identity was maintained through an alignment of behaviour with other members of the online social group. Many health promotion programmes are underpinned by social cognitive theory, with its focus on the interaction of behaviour, internal personal factors (biology and individual cognition) and environmental influences and the key concepts of agency, self-efficacy, vicarious reinforcement and motivation.

Planning your course effectively – more overlaps

Cog blue corrected

Similarly to the biological approach, there are many overlaps between the cognitive approach and the options of abnormal psychology, development, health and human relationships.  For example, the psychology of cognitive processes and their reliability can explain clinical biases in diagnosis of disorders, debates regarding the etiology of  disorders and also inform their treatment.

Watch out for more of these!

Planning your course effectively – exploiting the overlaps

Bio_HR Image - green

Here is some support when planning for the new school year. This is one of the most useful exercises I have ever done before teaching a course on psychology. Using a table, or a simple Venn diagram, as above, identify the overlaps between the core approaches and the options. Putting these posters around your class, sharing them with students, and using them for your own planning can clarify and structure your thinking and theirs. This is so useful when it comes to revision.

For example, as we can see, the biological approach to human relationships comprises mainly evolutionary psychology arguments. The same overlaps mapped between biology and abnormal psychology would identify brain neurochemistry as a key conceptual argument. The biological approach to childhood development looks at brain development and neuronal networking.

Doing this helps immensely with understanding the big picture, and also minimising the studies one needs to cover. If teaching the human relationships option later in your course, when students are learning about evolutionary psychology in the biological approach earlier in your course – here are their examples.

I will be mapping more of these over the following weeks, so watch out for them before term starts!
