Abstract
ABSTRACT Drawing a hypothesis from embodied theories of memory, van Dam, Rueschemeyer, Bekkering and Lindemann [(2013). Embodied grounding of memory: Toward the effects of motor execution on memory consolidation. The Quarterly Journal of Experimental Psychology, 66(12), 2310–2328] showed that recognition performance for action words could be modulated by actions performed during the retention interval, suggesting that motor actions during the retention interval affect memory consolidation. The results of 4 experiments from two different laboratories, designed to replicate and extend the van Dam et al. motor consolidation effect, are presented here. Two of the experiments (n = 30 and n = 44) exactly and independently replicated the experimental design and conditions of the original experiment. Yes/No recognition scores plus additional analysis of response times showed no motor consolidation effects. A third experiment (n = 44) manipulating type of processing during encoding also failed to find significant motor consolidation effects. Finally, a fourth experiment (n = 120) following a more standard reconsolidation paradigm, involving 24-hour intervals between learning and motor behaviour, and a 24-hour delayed test, also found null effects. The absence of effects of motor execution on memory consolidation is discussed in terms of the implications of these findings for the embodiment approach to cognition.
