"Previous research has revealed a moderate and positive correlation between procrastination and impulsivity. However, little is known about why these two constructs are related. In the present study, we used behavior-genetics methodology to test three predictions derived from an evolutionary account that postulates that procrastination arose as a by-product of impulsivity: (a) Procrastination is heritable, (b) the two traits share considerable genetic variation, and (c) goal-management ability is an important component of this shared variation. These predictions were confirmed. First, both procrastination and impulsivity were moderately heritable (46% and 49%, respectively). Second, although the two traits were separable at the phenotypic level (r= .65), they were not separable at the genetic level (rgenetic = 1.0). Finally, variation in goal-management ability accounted for much of this shared genetic variation. These results suggest that procrastination and impulsivity are linked primarily through genetic influences on the ability to use high-priority goals to effectively regulate actions."

"Not everyone is destined to follow one misdeed with another, but a new study reveals what type of person is likely to be a “repeat offender”. In a series of experiments, behavioral researcher Shu Zhang of Columbia Business School and her colleagues found that people who derive a sense of security from the status quo are significantly more likely to follow one ethical lapse with another than are people who are comfortable with change."

What causes personality maturation in early adulthood? Some researchers say maturation is determined by genetic factors (five-factor theory); others say it is related to culture-specific expectations for behavior at a certain age (social-investment theory). In the research reported here, Bleidorn et al. (2013) examined Big Five personality data, collected as part of the Gosling-Potter Internet Personality Project from participants in 62 countries, and indices of the timing of a variety of socially normative behaviors — such as marriage, parenthood, and entry into the workforce — for those countries. Although personality did mature as people aged, the faster maturation found in countries with earlier transition to adult roles supports social-investment theory.

Work on synesthesia has predominantly focused on confirming the authenticity of synesthetic experience, but much less research has been conducted to examine the extent to which synesthesia is linked to broader perceptual differences. The research reported here examines whether synesthesia is associated with differences in color and motion processing by comparing these abilities in synesthetes who experience color as their evoked sensation with nonsynesthetic participants.
