We investigated the effect of correlation in background noise on the ability of participants to detect a kinaesthetic target on the index fingers of their hands. Participants had to judge whether the target (a smoothed ramp with quarter-sine onset and offset), was on the left or right finger (experiments 1 and 2). These targets were embedded in noise generated by pseudo-random up-down movements of both the left and right fingers. Positive correlation between the noise on the left and right fingers aided discrimination of the target signal relative to when the noise was uncorrelated. However, this benefit of positive correlation was subject to temporal limitations and diminished with increasing lag between the noise on the fingers (experiment 2). Tests of explicit detection of correlation in kinaesthetic noise (experiment 3) showed a similar pattern, with detection of correlation decreasing with the temporal lag between the noise on the fingers. The results suggest that kinaesthetic signal detection involves sensory integration across the fingers within a limited temporal window.
