Wrinkle: Moving Wet Objects with Wrinkled Fingers
In Stat2Data: Datasets for Stat2

Results from an experiment to move wet/dry objects with wrinkled/dry fingers

A data frame with 80 observations on the following 7 variables.

Participant: Participant ID (p1 to p20)
Time: Time to move objects (seconds)
Condition: non-wrinkled/dry, non-wrinkled/wet, wrinkled/dry, or wrinkled/wet
Fingers: Status of fingers (non or wrinkled)
Objects: Status of objects (dry or wet)
WrinkledThenNon: Wrinkled first? (1=yes or 1=no)
DryThenWet: Dry first? (1=yes or 1=no)

Each of 20 participants were measured doing a "transfer task" several times under each of four conditions. The transfer task was to pick up an item with the right hand thumb and index finger, pass the item through a small hole and grab it with the left hand, and then put the item into a box that had a hole in the lid. Sometimes the participant's fingers were wrinkled; sometimes the items were sitting in water.
