Self-presentation is an intricate cognitive-behavioral process by which a person tries to influence her public appearance, i.e., the way she is perceived and experienced by other people, in order to create the best possible impression of herself. The phenomenon has come into the focus of scientific interest after the publication of Ervin Goffman’s seminal work The Presentation of Self in Everyday Life (1959.) in which the author metahporically explains the self-presentational behavior by comparing it to the behavior of actors on a stage. People use self-presentation in order to either be more liked by other people or to achieve specific goals. This process can take place either at the conscious or at the unconscious level, either spontanously or intentionally. Depending on individual differences, in different situations people use different means of self-presentation. In addition to the ordinary (“face-to-face”) method, people nowadays often use cyberspace to boost their self-image. For instance, social network users create their “profiles” by which they initially present themselves to other users. Different authors use different taxonomies to scrutinize self-presentational behavior, depending on the features they see as important. Regardless of these differences, it has become common to discriminate between several basic means and tactics of self-presentation. According to the mostly accepted taxonomy, the tactics of self-presentation can be classified into two elementary types: assertive (ingratiation, intimidation, self-promotion, and exemplification) involving proactive behavior of the self-presenter, and defensive tactics (excuses, justifications and self-handicapping) which are aimed at correcting the previously damaged self-image. In the final chapter of the thesis, the previously explicated tactics are illustrated by four original examples from everyday life: the job interview, the first date, the fare-dodging in public transport, and the self-presentation on a social network.
