For Higher Psychology, the topic you choose will depend on the SQA 'research brief' which is published every year - we can't do topics that don't fit with their guidance. However, if the choice is reasonably flexible (as in the past), then the following would be suitable options:
- A study of highlighting - does the use of a highlighter pen help people to remember key facts? See for example Yue, Storm, Kornell and Bjork (2014), but Dunlosky and Rawson (2015) have a different view.
- Spacing as we learn - a replication of Kornell's (2009) flashcards study.
- Suppressing the white bears - can we prevent unwanted thoughts? A study based on the work of Wegner.
- A study of the testing effect - compare doing a test with re-reading, keeping other factors constant. Refer to the work of Roediger and Karapicke (2006).
- Attentional processes - the 'Stroop' effect.
- Beliefs about learning - how well do student beliefs about learning and memory fit with what is known to work? A survey study based on e.g. Kornell and Bjork (2007).
- Evolutionary aspects of memory - do people remember risky things better than neutral objects? Comparison of objects and various types of objects and animals. Could include both short-term and long-term tests. See work of Nairne and colleagues e.g. Nairne (2013).
- Perception of art: how quickly can we learn to categorise different types of artwork? What about maths or science problems? Interleaving could play a role here - see Kornell and Bjork (2008); Rohrer et al (2015).
- The role of simple repetition when learning language vocabulary - is rehearsal enough? Classic research by Craik and Watkins (1973) suggests not, but more recent studies have shown that it does have an important role. Design a suitable experiment.
- Correlation study of IQ v's exam results. It would be important to disentangle IQ and WM, and to consider social factors in educational attainment.
Whatever you choose to do, ensure that it follows ethical guidelines - your participants should be over 16, and you shouldn't harm or stress them in any way. Ensure that they give informed consent, and are aware of their right to withdraw at any point. Debrief them afterwards, and keep all data confidential.
