“Second-Guessing” Is a Hard-Wired Behavior, Study Suggests

Copy-cat? Youth with Few Friends Conform to Stay in a Friend’s ‘Good Graces’
What gives one friend influence over another? Considerable attention has focused on who influences whom; much less is known about why one partner is prone to be influenced by the other. A study tested the hypothesis that within a friend dyad, having fewer friends than one’s partner increases susceptibility to influence, because it reduces dissimilarity and promotes compatibility. Results showed that partners with fewer friends were influenced by children with more friends. In each case, the partner with fewer friends became more similar to the partner with more friends. Academic engagement was the only domain where partners with fewer friends also influenced partners with more friends.

Rare Human Gene Variant in ADHD, Autism Exposes Fundamental Sex Differences
Key differences in male and female mice brains provide new insights into how sex determines the mechanisms by which distinct synapses monitor and regulate dopamine signaling. The impact of sex differences is particularly pronounced when the mice express a human genetic variant found in boys with either ADHD or autism. Behavioral generalizations across the sexes may limit diagnosis of mental illness, especially if one sex translates alterations into outward signs such as hyperactivity and aggression vs. more internal manifestations such as learning, memory and mood, even when the same molecular pathology is at work.

‘Octo Girl’ Takes a Deep Dive to Discover How Diverse Octopus Species Coexist
A first in situ, long-term study explored how the common octopus, a medium-sized octopus widely distributed in tropical and temperate seas worldwide and the Atlantic longarm octopus, a small species of octopus found in the Atlantic Ocean and elsewhere, coexist by examining their foraging habits and tactics, diet, behaviors and when they are active or inactive. Results show that their very different behaviors and habits is exactly how these two species coexist in a shallow Florida lagoon- even at high densities.
Massive Study Links Nearly 600 Genomic Regions to Self-Regulating Behaviors

Do Passengers Want Self-driving Cars to Behave More or Less Like Them?
Researchers asked participants about their personal driving behaviors such as speed, changing lanes, accelerating and decelerating and passing other vehicles. They also asked them the same questions about their expectations of a self-driving car performing these very same tasks. The objective of the study was to examine trust and distrust to see if there is a relationship between an individual’s driving behaviors and how they expect a self-driving car to behave.
