Igt Lab Report

Decent Essays

The aim of this report was to test the direct replicability of the IGT, and see whether it matched the original results. The original study showed that overall, healthy participants in the control category had a strong liking for the “good” decks. The error bars highlight that there is a difference in the frequency of selection between the ‘bad decks’ Deck A and B and the ‘good decks’ Deck C and D. This relationship is the focus of the experiment. As the error bars of the ‘good decks’ do not overlap with the error bars of the ‘bad decks’ the results suggest they are significantly different. Thus, the direct replication provides support for Bechara et al’s findings, namely the assumption that healthy individuals will select the “good” …show more content…

This creates conflict on which results to believe. A limitation of direct replication is confirmation bias, this is where a researcher searches for and or interprets data in a way to confirm their hypothesis. This involves illusory correlation, drawing links between data that are not real. However, research is mostly standardised and controlled thus, in most cases should not impact study replication. To conduct research multiple times is time intensive as well as expensive and thus unrealistic to implement. However, the publishing of research should be taken into more consideration. Practices such as peer review are imperative to prevent false information from being published. Published research has a profound impact on further research and it is difficult to discredit research once it has been published. Another difficulty with research across all disciplines of science is the file drawer problem. This is where research studies across all fields are more likely to be published if they produce positive findings than non-significant or negative ones. This has been suggested to affect the validity of research especially in meta-analysis which use these data. However, in contrast research from (Dan R Dalton, 2012) has shown that the file drawer effect ‘does not produce an inflation bias’ to the extent currently assumed. A dominating question in the replication crisis, is how should researchers tackle the
