If you want to have a clear understanding of the meaning of "psychologem", you have to understand Carl Jung's notions of "archtype" and "collective unconscious".

According to Jung, the psychologem is "an archetypal psychic structure of extreme antiquity". In his clearest manifestations, he is a faithful copy of an absolutely undifferentiated human consciousness, corresponding to a psyche that has hardly left animal level.

In other words, the psychologem is "the subjective presentation of different aspects of one's present identity". This idea has great relevance in Jung's notion of collective unconscious.

Collective unconscious: In Jungian psychology, a part of the unconscious mind, shared by a society, a people, or all humankind, that is the product of ancestral experience and contains such concepts as science, religion, and morality.
