CAN GROUP MEMBERS RECOGNIZE THE EFFECTS OF GROUP DISCUSSION UPON RISK TAKING?

Crows cross-modally recognize group members but not non-group members.

Recognizing other individuals by integrating different sensory modalities is a crucial ability of social animals, including humans. Although cross-modal individual recognition has been demonstrated in mammals, the extent of its use by birds remains unknown. Herein, we report the first evidence of cross-modal recognition of group members by a highly social bird, the large-billed crow (Corvus mac...

Risk-taking in social settings: Group and peer effects☆

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark treatments replicate findings that groups take more risk than individuals in the investment task; con...

Indirect genetic effects on the sociability of several group members

http://dx.doi.org/10.1016/j.anbehav.2016.10.028 0003-3472/© 2016 The Association for the Study of A Indirect genetic effects (IGEs) are a major driver of social evolution, but much of the experimental work pertaining to IGEs on social behaviour has focused on the effect of stimulus individuals on single focal individuals. We extended IGE research to examine how stimulus individuals influence so...

A study of the effects of group discussion with male high school students on their parents’ hypertension control

Hypertension is one of the most important preventable causes of premature morbidity and mortality in developed and developing countries. Raising family knowledge and involvement of family members in care delivery can help to promote positive hypertensive patient behaviors, such as appointment keeping, compliance with therapy, and better hypertension control. The present study seeks to assess th...
