Mean scores in survey responses, grouped by experience level

Question	Mean Score (± Standard Deviation)
Question	All Subjects (n = 19)	Experts (n = 5)	Novices (n = 14)
Tactile Feedback helped me perform the task	3.84 (±0.69)	3.60 (±0.89)	3.93 (±0.62)
Tactile feedback had no effect on my performance	2.37 (±1.01)	2.80 (±1.10)	2.21 (±0.97)
With tactile feedback, I grasped tissue with less force	4.11 (±0.81)	3.80 (±0.84)	4.21 (±0.80)
The balloon inflations were easy to feel	4.37 (±0.76)	4.40 (±0.55)	4.36 (±0.84)
I found myself ignoring the balloon inflations	1.84 (±0.76)	2.00 (±0.00)	1.79 (±0.89)
The balloon inflations were intuitive	3.79 (±0.79)	3.80 (±0.84)	3.79 (±0.80)
The inflations became more difficult to feel over time	2.00 (±0.75)	2.00 (±0.71)	2.00 (±0.78)
Avoiding drops was my highest priority	2.84 (±1.01)	2.80 (±0.84)	2.86 (±1.10)
Delicate grasping was my highest priority	3.53 (±0.84)	3.60 (±0.55)	3.50 (±0.94)
