which psychological perspective is concerned with how the unconscious conflicts and drives shape thought and behavious

The Psychodynamic perspective is concerned about this.

Explanation:

The Psychodynamic Approach developed from Freud's Psychoanalytical Approach, which centers on the idea that an individual's behaviors are mainly driven by his/her unconscious.

One's behaviors and conducts are driven by past experiences, which leave a mark even if the individual is not aware, this is what we understand as the unconscious. As Freud believed, an individual's first years of life and first interactions shape all of his/her future interactions.
