Key Studies for the IA
A list of good studies to replicate for the IB Psychology Internal Assessment.

Travis Dixon Internal Assessment (IB) 2 Comments

Remember that actually in the new IB Psych curriculum (first exams May 2019) the theory is actually more important than the study. In fact, you could even conduct the IA successfully without replicating a study but by designing your own experiment that tests a theory. However, it is strongly advised that you replicate an original study, simplify it (if necessary) to two conditions and …

Key Study: Leading questions and the misinformation effect – ” the car crash study” (Loftus and Palmer, 1974)

Travis Dixon Cognitive Psychology, Internal Assessment (IB), Key Studies, Studies and Theories Leave a Comment

 Memory is a reconstructive process, which means memories are actively and consciously rebuilt when we are trying to remember certain things. Elizabeth Loftus, her colleagues and others studying this cognitive phenomenon have shown that during the reconstruction phase our memories can be distorted if we are given false information about the event – this is called the misinformation effect. Background Information …

Demand characteristics: What are they really?

Travis Dixon Internal Assessment (IB), Research Methodology, Teaching Ideas Leave a Comment

I was reading another research methods chapter in a new psychology textbook the other day and despite it’s excellent content in research methodology, it still (I think) mis-defined demand characteristics.  The most common definition of demand characteristics out there goes something like, “demand characteristics are when participants are aware of the aim of the research and change their behaviour in a …

Internal Validity: And why I don’t teach it…

Travis Dixon Curriculum, Internal Assessment (IB), Research Methodology Leave a Comment

I’d love to hear how you feel about my rationale for not teaching students how to evaluate studies based on internal validity. There is one exception, however: their IA. I only introduce the concept of internal validity during the analysis of their IA results and procedures, as this is the only study I expect them to be able to make …

This will become important later on when you apply the inferential statistics to your data. The purpose of …

Hypotheses (HL)

Travis Dixon Internal Assessment (IB), Research Methodology 3 Comments

What you need to know…             HL students need to have an experimental and a null hypothesis. They should make note if their experimental hypothesis is one-tailed or two-tailed as this will be important when they come to conduct the statistical tests. When researchers make a prediction it’s only natural to want to “prove” that prediction right. So a null …
