An experimental psychologist investigated motor skill acquisition using a high-precision haptic feedback glove. Participants had to trace a complex 3D curve projected in virtual space. Every time they successfully completed the trace within a tolerance threshold, a soft audio-chime indicated success.
Each participant completed one 15-minute training session per day for 4 days in a sound-proofed laboratory environment. The researcher recorded the number of successful traces completed by a participant, Patient J, during each session.
The recorded frequencies are shown in Table 1 below.
Table 1: Frequency of successful 3D traces over four daily training sessions
| Day 1 | Day 2 | Day 3 | Day 4 | |
|---|---|---|---|---|
| Number of successful traces | 2 | 9 | 18 | 31 |
