What is it about?

This study delves into human cognitive abilities, particularly focusing on how we retrieve information from memory (referred to as Gr). We explored whether the time we take to retrieve information affects how we measure this ability. Additionally, we examined if tasks involving different types of retrieval, like verbal or visual, affect our understanding of Gr. Our findings suggest that regardless of retrieval time or type, Gr remains a distinct and important factor in cognitive abilities. We found that 62% of the variation in Gr could be explained by factors like memory and intelligence, highlighting its significance. However, there's still 38% of individual differences in Gr that aren't accounted for, indicating more research is needed. In summary, our study enhances our grasp of Gr's dimensionality and its role in cognitive abilities.

Why is it important?

This study advances our comprehension of cognitive abilities by elucidating the structure of retrieval ability. It underscores that time limits in retrieval tasks don't change what's measured, aiding efficient assessment methods in practical settings like neuropsychological assessments, offering potential savings in time and costs.


Conducting this study was a great pleasure for me, as I was able to work with amazing and knowledgeable colleagues on it. This article has been the last manuscript of my dissertation and is the first study to be published from a larger set of studies within the given project. I hope that this article highlights the relevance of taking a multivariate view of psychological variables and I am looking forward to further research regarding retrieval ability.
