UNBC - Call for Grey Literature

The University of Northern British Columbia is requesting grey literature on motor facilitation and interference effects in higher-order cognitive tasks.

Researchers in the department of Psychology at the University of Northern British Columbia are
requesting unpublished findings for a meta-analysis:

“How do dual-tasks that interfere with motor processes influence
memory, conceptual thinking, or higher cognitive processes”


Aim: This meta-analysis aims to establish the directionality and significance of motor-task
interference paradigms in the domains of memory, conceptual thinking, and other higher-order
cognitive processes. In these paradigms, participants perform a primary higher-order cognitive
task (e.g. conceptual judgment, lexical decision, word-list memory, picture naming, etc.) while
also performing a secondary motor-task (gripping an apparatus, performing a simple motor
sequence, etc.). The effects of this dual task on performance are often compared to an active or
passive control condition. Within the dual-task literature there are mixed results, with some
reports that the motor task interferes with higher order cognitive processing, some reports that
the motor task facilitates processing, and some reports of no effects. These results are
especially important for assessing claims related to theories of embodied or grounded
cognition, and have major implications for mechanistic neuroscientific models of higher order
cognition, and therefore are important for our understanding of memory, language, conceptual
knowledge, and imagination.

We are requesting the following:

  • unpublished academic research and theses
  • unpublished non-significant findings
  • complete data sets that have not been prepared for publication
  • data or results that are being prepared for publication or are under review

Submitted projects must have the following features:

  • A motor task must be performed at the same time as a higher-order cognitive task
  • The motor task can be any form of motor interference broadly considered (ex: clapping pattern, flexion of muscles, topical anesthetic, fatiguing muscle groups, etc)
  • The research includes a control condition
  • Means and standard deviations must be available or calculable from provided data
  • Research may have been completed in any year

Please send inquiries or submissions no later than Sept. 1, 2021 to:
