Attitudes refer to the opinions and responses we have to a variety of circumstances, to others and to us. They include physical and emotional positions, either conscious or unconscious, that are present, especially while interacting with others.
These attitudes are active in daily life and can affect others and ourselves in positive or negative ways.
Perceptions in this context refer to the worldviews of individuals. They consider the way we gain, construct and mediate knowledge, and how we understand situations, events and peoples.
Personal histories affect attitudes and perceptions, so too attitudes and perceptions affect personal histories.
