Figure 1 with 1 supplement
Experimental methods, hypotheses, and results of Experiment 1 (n=30).
(A) In the contact condition (magenta), participants tapped with their right index finger ‘R’ on a force sensor placed above the probe that delivered a test force of 2N to their left index finger …
Figure 1—figure supplement 1
Fitted logistic models based on the participants’ responses under each condition of Experiment 1.
Figure 2 with 1 supplement
Experimental methods, hypotheses, and results of Experiment 2 (n=30).
(A) The contact (magenta) and no-contact (green) trials were identical to those of Experiment 1, with the only difference that in 50% of the trials, the participants had to inhibit their movement (NO…
Figure 2—figure supplement 1
Fitted logistic models based on the participants’ responses under each condition of Experiment 2.
Figure 3 with 3 supplements
Experimental methods, hypotheses, and results of Experiment 3 (n=30).
(A) The contact (magenta) and no-contact (green) conditions were identical to those of Experiment 1, with the only difference being their relative proportion (contact trials 80%, no-contact trials …
Figure 3—figure supplement 1
Fitted logistic models based on the participants’ responses under each condition of Experiment 3.
Figure 3—figure supplement 2
Distance between the fingers (contact condition minus no-contact condition) for each experiment at the time of the test force for each experiment (n=30).
Box plots show the median and interquartile ranges, raincloud plots show individual participant values and their distribution. Values below zero indicate that the fingers were closer together for …
Figure 3—figure supplement 3
Forces exerted on the left index finger (Test force) and on the force sensor by the right index finger (Peak active force) (n=30).
(A–C) Average test forces (mean ± SEM) exerted on the participants’ left index finger for the contact (magenta traces), no-contact (green traces), and baseline (blue traces) across all experimental …
