The third wave of cognitive behavior therapy is a general term for a group of psychotherapies that arose in the 1980s, inspired by acceptance and commitment therapy (ACT).
To me, third wave therapies seem more realistic than older therapies because they accept emotions as they are and pay close attention to how they function in the moment.
The link above is well-worth reading. The frames of these therapies are also well-worth considering.
FIML, which I am calling a “fourth wave cognitive behavior therapy,” differs from third wave therapies in that FIML does not use a professional therapist. Instead, partners become their own therapists.
Moreover, how FIML partners frame their psychologies or generalize their behaviors is entirely up to them. Similarly, their psychological goals and definitions are entirely in their own hands.
At its most basic, FIML “removes wrong interpretations of interpersonal signs and symbols from the brain’s semiotic networks.”
This process of removal, in turn, shows partners how their minds function in real-time real-world situations. And this in turn provides the tools and perspectives to reorganize their psychologies in whichever ways they like.
FIML is based on semiotics because semiotics are specific and with practice can be clearly identified and understood. They give partners “solid ground” to stand on. Words, tone of voice, gestures, and facial expressions are some of the major semiotics partners analyze.
Using real-world semiotics as an analytical basis frees FIML from predetermined frameworks about personality or what human psychology even is. With the FIML tool, partners are free to discover whatever they can about how their minds communicate interpersonally (and internally) and do whatever they like with that.
