Cookson, S. L., D’Esposito, M. (2022) HBM :: Brain network definitions typically assume nonoverlap or minimal overlap, ignoring regions’ connections to multiple networks. However, new methods are emerging that emphasize network overlap. Here, we investigated the reliability and validity of one assignment method, the mixed membership algorithm, and explored its potential utility for identifying gaps […]

Connectivity-defined subdivisions of the intraparietal sulcus respond differentially to abstraction during decision making
Newton, M., Cookson, S. L., D’Esposito, M., Kayser, A. (2022) J Neurosci :: The intraparietal sulcus (IPS) has been implicated in numerous functions that range from representation of visual stimuli to action planning, but its role in abstract decision-making has been unclear, in part because low-level functions often act as confounds. Here, we address this […]
Dissociating the neural correlates of planning and executing tasks with nested task sets
Cookson, S. L., Schumacher, E. H. (2022) JOCN :: Task processing (e.g., the preparation and execution of responses) and task representation (e.g., the activation and maintenance of stimulus–response and context information) are two facets of cognitive control supported by lateral frontal cortex (LFC). However, the mechanistic overlap (or distinction) between these two facets is unknown. […]
Centering inclusivity in the design of online conferences – An OHBM – Open Science perspective.
Levitis, E., Gould van Praag, C., Gau, R., … Cookson, S. L. … Maumet, C. (2021). Gigascience :: As the global health crisis unfolded, many academic conferences moved online in 2020. This move has been hailed as a positive step towards inclusivity in its attenuation of economic, physical, and legal barriers and effectively enabled many […]
Task sets serve as boundaries for the congruency sequence effect
Grant, L. D., Cookson, S. L., Weissman, D. H. (2020) JEPHPP :: Cognitive control processes that enable purposeful behavior are often context-specific. A teenager, for example, may inhibit the tendency to daydream at work but not in the classroom. However, the nature of contextual boundaries for cognitive control processes remains unclear. Therefore, we revisited an […]
Task structure boundaries affect response preparation
Cookson, S. L.*, Hazeltine, E., Schumacher, E. H. (2019) Psychological Research :: Does cognitive control operate globally (across task sets) or locally (within a task set)? Recently, two of the current co-authors (Hazeltine and Schumacher 2016; Schumacher and Hazeltine 2016) proposed that humans represent tasks as task files: hierarchically structured, compartmentalized subsets of our current […]
Dual-task processing with identical stimulus and response sets: Assessing the importance of task representation in dual-task interference
Schumacher, E. H., Cookson, S. L.*, Smith, D. M., Nguyen, T. V. N., Sultan, Z., Reuben, K. E., Hazeltine, E. (2018). Frontiers in Psychology :: Limitations in our ability to produce two responses at the same time – that is, dual-task interference – are typically measured by comparing performance when two stimuli are presented and […]
Neural representation of stimulus-response associations during task preparation
Cookson, S. L.*, Hazeltine, E., Schumacher, E. H. (2016). Brain Research :: A partially informative cue presented before a stimulus can facilitate the production of the response. Prior information about an upcoming target can increase brain activity in both stimulus (c.f., Desimone and Duncan, 1995) and response (c.f., Leuthold et al., 1996) processing regions; however, […]
