An important and vital question, especially as Big Tech seeks to immerse us further and further into "metaverses" and embodied experiences. See my answer here.

There are all kinds of technologies. out there but cybertechnology, in particular, encompasses a wide range of computing and communications devices.

In short, media psychology is the study of how our creation, consumption, and distribution of media — namely through mediated technologies — influences our behavior.

Broadly speaking, interaction design involves designing interfaces for technological products, namely at the level where humans and technology "meet" or interact. The general goal of interaction design is to facilitate seamless and graceful "technology touchpoints" so they are beautiful, emotive, functional, and easily fit into our everyday lives. The other side of the coin, however, is that despite its aesthetic presentations and best functional intentions, interaction designs also make technology (and its inner, computational parts and underpinnings) opaque. The latter is a reality that incurs psychological impact to the user, which is a subject that falls more into the cyberpsychological realm.

Cyberpsychologists aim to (a) impose or maintain "a balance" of sorts between technology and our humanity, one that nurtures and protects human-centeredness; and (b) explore the psychological impact(s) caused by our growing enmeshment with computational technologies.

The short answer is that cyberethics refers to the moral implications of cybertechnologies, but for a more expansive answer, read this.

As a niche of media psychology, social media psychology in particular explores how so much of our everyday lives is played out on social media platforms, and how our social media interactions can impact our identity, wellbeing and relationships.
