| Annotation | The Stroop effect is one of the best-known effects in cognitive psychology. Research participants typically take much longer to name the ink colour of a colour word depicting a different colour to the ink colour (i.e., the word `green' printed in red) than to name the colour of a patch of colour. In this meta-analysis, data from 20 studies comparing younger and older adults on the Stroop interference effect, contained in 15 articles, were analysed. No significant difference was found in the Stroop interference effect between the two age groups. Moderator variables were present but did not produce age differences. Brinley analysis showed that a single regression line with a slowing factor of 1.9 described the data well and confirmed that no age x condition interaction was present in the data. Similarly, no age x condition interaction was found when the data were fitted to the information loss model; the age ratio of decay rates was estimated to be 1.4. The study concluded that the apparent age-sensitivity of the Stroop interference effect appears to be an artefact of general slowing. (AKM). |
