Hi!
I am trying to segregate different components of verbal working memory and visuospatial working memory.
In order to assess verbal working memory I am using an auditory version of n-back task with a load level from 1 to 2. The task requires the participant to respond when they here the same consonant repeatedly (1-back condition) or when they hear the same consonant at an interval of another consonant (2-back condition)
In order to assess visuopatial working memory I am using a spatial n-back task. The memory load ranges from 1 to 2. A set of cards are shown to the subjects sequentially, each card has a small back color dot on a white background. The position of the dot changes from card-to-card. The subject has to respond when they saw the dot appearing on the same location in comparison to the previous card (1-back condition) or after an interval of one card (2-back condition).
I am not sure whether it can segregate the components of verbal and visuospatial working memory.
Is there an article that might give me a clue as what component is tapped in the 1 n-back load level and 2 n-back load level?
Thanks

Hi Vatsal,
Yes, I think it is possible to discriminate between verbal and visuospatial WM processes with a n-back test. For example, in the attached paper (Luis et al., 2015), a N-back paradigm design which included the combination of four conditions and two memory loads is used to test for such differences.

Hi Vatsal,
Maybe this paper can help too: Pelegrina S, Lechuga MT,
