A psychology researcher at North Carolina State University is proposing a new theory to explain why older adults show declining cognitive ability with age, but don’t necessarily show declines in the workplace or daily life. One key appears to be how motivated older adults are to maintain focus on cognitive tasks.

When we feel mentally stressed, we often also feel physiological changes, including a faster heart rate and an increase in body temperature. This increase in body temperature is known as psychological stress-induced hyperthermia, which is a basic stress response broadly observed in mammals. The response is helpful for warming up the muscles during "fight or flight" situations, such as when wild animals face their enemies; however, stress for people in today's society can last a long time and cause a chronic increase in body temperature, a condition called psychogenic fever, which brings on intense fatigue.

While touch always involves awareness, it also sometimes involves emotion. For example, picking up a spoon triggers no real emotion, while feeling a gentle caress often does. Now, scientists in the Cell Press journal Neuron describe a system of slowly conducting nerves in the skin that respond to such gentle touch. Using a range of scientific techniques, investigators are beginning to characterize these nerves and to describe the fundamental role they play in our lives as a social species—from a nurturing touch to an infant to a reassuring pat on the back. Their work also suggests that this soft touch wiring may go awry in disorders such as autism.
