Normative data for elderly adults: the Maine-Syracuse study.

The primary objective of this study was to provide supplementary normative data on aging and cognition from an ongoing community-based study. This dementia- and stroke-free sample (age range = 70-89; mean = 77.5) consisted of 228 women and 155 men participating in the Maine-Syracuse Longitudinal Study at waves 6 to 7 (2001-2009).

Synesthesia affects verification of simple arithmetic equations.

To investigate the effects of color-digit synesthesia on numerical representation, we presented a synesthete, called SE, in the present study, and controls with mathematical equations for verification. In Experiment 1, SE verified addition equations made up of digits that either matched or mismatched her color-digit photisms or were in black. In Experiment 2A, the addends were presented in the different color conditions and the solution was presented in black, whereas in Experiment 2B the addends were presented in black and the solutions were presented in the different color conditions.
