Cognitive Load and Peace Attitude Influence Cooperative Choices in the Iterated Prisoner's Dilemma Game.

Human society and its development are based on the principle of cooperation. The choice of a cooperative strategy in a context of uncertainty, such as the iterated Prisoner's Dilemma game, can be influenced by many factors, both individual and situational. However, there is limited evidence regarding how these factors affect strategic choices when players are subjected to cognitive load conditions.

No Evidence of Perceptual Pseudoneglect in Alexithymia.

Neuroscience research links alexithymia, the difficulty in identifying and describing feelings and emotions, with left hemisphere dominance and/or right hemisphere deficit. To provide behavioral evidence for this neuroscientific hypothesis, we explored the relationship between alexithymia and performance in a line bisection task, a standard method for evaluating visuospatial processing in relation to right hemisphere functioning. We enrolled 222 healthy participants who completed a version of the 20-item Toronto Alexithymia Scale (TAS-20), which measures alexithymia, and were asked to mark (bisect) the center of a 10-cm horizontal segment.
