This book focuses on the latest developments in psychology research. Chapter One reviews literature regarding sleep, nutrition, and weight status, addresses the dearth of research related to the interplay of these topics, and discusses interventions. Chapter Two studies frequent and recent aggression in individuals with high and low trait anger. Chapter Three presents a new, developmentally-oriented and integrative model of the factors that might lead to personality change. Chapter Four focuses on the attentional biases in bipolar depression. Chapter Five reviews recent research about the theoretical basis of attentional training and examines the evidences about its efficacy in the treatment of depression. Chapter Six presents research on the exclusion and inclusion of people with mental suffering in the territorialization processes of the national politics concerning mental health in Brazil. Chapter Seven discusses discursive strategies in the hands of media manipulators. Chapter Eight examines certain components of environmental psychology and argues that insufficient attention has been paid to their role in the understanding of human wildlife relations, taking the example of El Salvador, in the Meso-American Biodiversity Hotspot.
