“The Tempo Anchoring Effect: A window into the relationship between  
beats, groove, and perceived musical tempo”

Abstract:
In a recent study of tempo perception, London et al. (2016) presented  
participants with R&B songs which had been "time-stretched", that is,  
sped up or slowed down without otherwise altering their pitch or  
timbre.  They found that while participants' relative tempo judgments  
(original versus altered versions) were correct, they no longer  
corresponded to the beat rate of each stimulus, which we called the  
"Tempo Anchoring Effect" (TAE).  Four experiments which further probe  
the relation between beat rate, time stretching, and perceived tempo  
are presented here.  Experiment 1 is a replication of London, et al.  
(2016) using the original stimuli.  Experiment 2 replaces the Motown  
stimuli with disco music, experiment 3 uses looped drum patterns, and  
experiment 4 had participants tapping along with the original stimuli.  
  The TAE was replicated in Experiment 1, present to a lesser degree  
in Experiment 2, and absent in Experiment 3.  The TAE persisted in  
experiment 4, even when participants accurately tapped at the beat  
rate of the stimuli. Experiments 2 and 3 also found that participants  
were able to make tempo judgments in accordance with BPM rates for  
stimuli that were not time-stretched.  These results imply that our  
sense of speed/tempo is a fairly high-level cognitive appraisal, while  
related perceptions (e.g., sensori-motor coupling, energeistic  
assessments, etc.) occur on lower cognitive or pre-cognitive levels.
