Stress and productivity patterns of interrupted, synergistic, and antagonistic office activities.

We describe a controlled experiment, aiming to study productivity and stress effects of email interruptions and activity interactions in the modern office. The measurement set includes multimodal data for n = 63 knowledge workers who volunteered for this experiment and were randomly assigned into four groups: (G1/G2) Batch email interruptions with/without exogenous stress. (G3/G4) Continual email interruptions with/without exogenous stress.

Absence of Stressful Conditions Accelerates Dexterous Skill Acquisition in Surgery.

The negative impact of strong sympathetic arousal on dexterous performance during formal surgical training is well-known. This study investigates how this relationship might change if surgical training takes place as a hobby in an informal environment. Fifteen medical students volunteered in a 5-week training regimen and weekly performed two standardized microsurgical tasks: circular cutting and simple interrupted suturing.
