Researchers have investigated the consequences of smelling the sorts of odors present in deserts when it rains.  Nabhan, Daugherty, and Hartung found that “Desert dwellers know it well: the smell of rain and the feeling of euphoria that comes when a storm washes over the parched earth. That feeling, and the health benefits that come with it, may be the result of oils and other chemicals released by desert plants after a good soaking. . . .

Hoendervanger’s multi-method dissertation probes who can most effectively use activity-based workplaces (ABW).  He shares that “a clear profile arises of workers who best fit with ABW environments, i.e.: high task variety, job autonomy, external and internal mobility, social interaction . . . low need for privacy; few high-complexity tasks, many non-individual tasks; appropriately using open and closed work settings; frequently switching between work settings; relatively young age.

Radun and colleagues investigated the effects of impulsive sound on cognitive performance.  They report that “Exposure to impulsive sound (65 dB LAeq) was compared with quiet sound (35 dB LAeq) and steady-state sound (65 dB LAeq). . . . Compared to quiet sound, impulsive sound caused more annoyance, workload, and lack of energy, raised cortisol concentrations, reduced systolic blood pressure, and decreased accuracy. . . . Compared with steady-state sound, impulsive sound was experienced as more annoying and causing a higher workload and more lack of energy.

Birman and Ferguson increase our understanding of the cognitive effects of listening to music.  They report that their study participants “were randomly assigned to four different groups: silence (no music), classical music, rock, and the final group could choose any genre they liked. The California Verbal Learning Test—Second Edition (CVLT-II) was administered to assess participant’s memory. Anxiety was also assessed before and after the memory test to see whether the music had any effect.
