The nested states model: a phenomenologically grounded model of the mind

THE NESTED STATES MODEL: A PHENOMENOLOGICALLY-GROUNDED MODEL OF THE MIND

The nested states model proposes linking phenomenological findings to clinical practice and dynamic models at the nervous system level by describing the layered structure of experience and its changes across different timescales.

The aim is to present a model of the mind that organizes findings from phenomenological psychopathology in a form usable in everyday clinical practice and connects them with biological research. The poster presents a theoretical model; no sample or empirical data are reported. According to the model, experiential states are layered (thought/image/sensation, emotional state, existential feeling, motivational state, level of arousal, lived body); each layer changes on its own timescale, and background states constrain the probability of foreground states emerging. This flow is illustrated through transition probabilities using the example of hunger-induced irritability (hanger): the motivational state of hunger facilitates an impatient existential feeling with a probability of 0.9, whereas the probability of a serene feeling is 0.1; impatience facilitates anger with a probability of 0.8 and joy with a probability of 0.2, while anger facilitates a rude remark with a probability of 0.9; when the constraints loosen, serenity has a probability of 0.6, shame 0.7, and a thought of regret 0.9. The framework was used to structure the description of the lived experience of depression by Fusar-Poli and colleagues (2023, World Psychiatry), with symptoms assigned to the layers. The model can be formulated as a recurrent neural network in which each state is an attractor state of the network; in depression, the range of states the system moves through is proposed to narrow predominantly to negative moods and emotions. In conclusion, brain states are also proposed to exhibit a nested structure comprising layers with different timescales of persistence. By establishing a structural homology between phenomenological and neural taxonomies, the model proposes integrating experiential and neural processes at a comparable level of granularity.
