Few phenomena in childhood are as compelling—and mystifying—as play. We review five proposals about the relationship between play and development. We believe each captures important aspects of play across species; however, we believe none of them accounts for the extraordinary richness of human play or its connection to distinctively human learning...
Developmental machine learning studies how artificial agents can model the way children learn open-ended repertoires of skills. Such agents need to create and represent goals, select which ones to pursue and learn to achieve them. Recent approaches have considered goal spaces that were either fixed and hand-defined or learned using generative model...

Objective This study was performed to compare the outcomes of laparoscopic common bile duct exploration (LCBDE) after failed endoscopic retrograde cholangiopancreatography (ERCP) versus primary LCBDE for managing cholecystocholedocholithiasis. Methods We retrospectively analyzed data from 59 patients who underwent LCBDE during laparoscopic cholecys...

Aging in women is associated with low estrogen, but also with cognitive decline and affective disorders. Whether low estrogen is causally responsible for these behavioral symptoms is not clear. Thus, we aimed to examine the role of estradiol in anxiety-like behavior and memory in rats at middle age. Twelve-month old female rats underwent ovariectom...
Scanning in football (soccer) denotes an active head movement where a player’s face is temporarily directed away from the ball to gather information in preparation for subsequently engaging with the ball. The aim of this study was to learn more about the ways that 27 elite professional football players in an English Premier League club use scanning...

Animal behaviour can lead to varying levels of risk, and an individual's physical condition can alter the potential costs and benefits of undertaking risky behaviours. How risk-taking behaviour depends on condition is subject to contrasting hypotheses. The asset protection principle proposes that individuals in better condition should be more risk ...

Angelman syndrome is a neurodevelopmental disorder presenting with severe deficits in motor, speech, and cognitive abilities. The primary genetic cause of Angelman syndrome is a maternally transmitted mutation in the Ube3a gene, which has been successfully modeled in Ube3a mutant mice. Phenotypes have been extensively reported in young adult Ube3a ...
On considère le problème de l'exploration d'une grille infinie par un nombre fini de robots. Ces robots ont une visibilité finie et exécutent tous le même algorithme de manière synchrone. Les robots ne possèdent pas de système de coor-données commun, mais sont chiraux (ils savent distinguer leur droite de leur gauche). Les robots possèdent une lumi...

Developmental scientists describe the role confusion that can occur for adolescents as they are forming a personal identity. Clinical psychologists describe low self-worth, lack of self-clarity, feelings of emptiness, and dissociation as the key elements of identity disturbance, and they link these to borderline personality disorder. In this study,...

Unconventional oil and gas exploitation, which has developed in the UK since 2009, is regulated by four main agencies: The Oil and Gas Authority, the Environment Agency, the Health and Safety Executive and local Mineral Planning Authorities (usually county councils). The British Geological Survey only has an advisory role, as have ad hoc expert com...
