The way we perceive ourselves in relation to the rest of the world influences our behaviors and our beliefs. The dynamics of psychology — cognition, perception, learning, emotion, attitudes and relationships — all play a significant role in how humans see themselves and the many elements in their environment.
Psychologists study how human behavior — from interpersonal relationships to recycling — affects our world. They study all aspects of the ways that psychology can improve our interactions with other people, places and things. Their research on human behavior can include issues as wide-ranging as prejudice, romantic attraction, persuasion, friendship, conformity, group interaction, learning, urban and city planning, environmental design, the influence of different environments on loneliness and stress, environmental health, and human responses to natural and technological hazards.
