Amara, a field biologist, spent months in a quiet, climate-controlled laboratory learning the precise sequence of steps to calibrate a sensitive DNA sequencer. However, when she was out in the humid, noisy tropical rainforest attempting to calibrate the device under pressure, she struggled to remember the correct steps. Instead, she found herself repeatedly performing the calibration steps for a different, older spectrophotometer she had used daily during her undergraduate studies three years ago.
