Kahneman in his book ‘Thinking fast and slow‘ elucidates the two type of thinking processes involved- a system I consisting of fast, intuitive processing, and a system II consisting of slower, more deliberate processing. Lesser known is the fact that a similar dual process theory of personality that precedes his work is by Seymour Epstien.

Epstien is know for his Cognitive-Experiential Self theory of Personalty (CEST), according to which he reintroduced the concept of unconscious in psychology, in the form of the Experiential system, but his unconscious was not maladaptive and instinct driven, but more adaptive in nature.

Essentially, Epstien acknowledges the massive role Experiential system has on the rational system, postulating that most of the behavior is Experiential driven and only pots hoc rationalized by the Rational system.

The Experiential system, though unconscious is not made up of repressed desires or works on the Pleasure principle, but instead is geared towards satisfying four basic needs. He later added two super-ordinate needs – one related to Valence or positive affcet- negative affect polarity and the other related to Arousal. Its pertinent to note that the Experiential system of CEST is very much affect driven and ‘hot’ rather than ‘cold’ in nature.

Essentially, Epstien himself tacitly split the four needs into eight by claiming that each need can be split around the super-ordinate need of positive affect- negative affect polarity. Here are the four basic needs made explicit.

In classical Freudian theory, the one most basic need before his introduction of a death instinct was the pleasure principle, which refers to the pursuit of pleasure and the avoidance of and pain (Freud, 1924/1960). Some learning theorists such as Thorndike (1927) make a similar assumption in their view of the importance of affective reinforcement. For object-relations theorists, most notably Bowlby (1988), the most fundamental need is the need for relatedness. For Rogers (1951) and other phenomenological psychologists, it is the need to maintain the stability and coherence of a person’s conceptual system. For Allport (1961) and Kohut (1971), it is the need to enhance self-esteem. (For a more thorough discussion of these proposals see Epstein, 1993, 1998b.) From the perspective of CEST, the four proposed basic needs all meet the following criteria for a basic need: the need is universal, the need can dominate the other basic needs, a failure to fulfill the need can destabilize the overall conceptual system.

These four basic needs may be satisfied to various degrees during critical developmental periods and lead to four basic types of beliefs. Even a scale has been created to measure these basic beliefs:

The Basic Beliefs Inventory (BBI). The BBI  (Catlin & Epstein, 1992) is a 102-item measure of beliefs associated with the satisfaction of four basic needs that motivate behavior according to CEST (see Epstein, 1991). The four basic beliefs are (1) the belief that the world is benign versus malevolent; (2) the belief that the world is meaningful (i.e., predictable, controllable, and just) versus chaotic (i.e., unpredictable, uncontrollable, and unjust); (3) the belief that relations with others are supportive versus threatening; and (4) the belief that the self is worthy (i.e., competent, good, and lovable) versus unworthy (i.e., incompetent, bad, and unlovable).

To me this aligns very well with the fundamental four model. To recap , as per the fundamental four model there are four polarities of basic motivations or drives: pleasure/ pain; active/passive; self/other and broad/narrow.

I would like to take this opportunity to expand the CEST and merge it with the fundamental four framework.

As per CEST, we all have beliefs or schema or models about self, others, the inanimate world and these are significantly involved in psychopathology.

I would propose that we have four basic models with 2 sub-models each. The four basic models are related to Life (where self and others or environment is not typically distinguished from each other), a Self model, an Other model and a World model.

Life model:

Life-past-and-present:  How do we view life that has already happened? If the experiences were mostly good, we see life as beautiful or benign; if the experiences were mostly bad, we view life as sucking or malevolent.

Life-yet-to-come: How do expect the future to be like? if we expect life to be full of adventure and hope we feel life is promising;  if we expect life to be mostly downhill, we feel that life is bleak.

Self model:

Self’s-impact-on-Env: How much control do we feel we have over our environment? Are we in control, can we chose our niches and are our efforts rewarded and effective? If yes we have feelings of positive self – esteem, otherwise we feel incompetent.

Env-Impact-on-self: Does our environment allow us any autonomy in regulating our behavior? Does it act for our benefit or to our advantage? If the environment provides unconditional positive regard, we develop positive self-worth and feel competent dealing with life’s curve-balls ; else we end up feeling worthless.

Other model:

Others-same-as-me: Am I part of the In-group? If we are accepted as part of the ingroup, our needs of belonging are satisfied; else we feel lonely.

Others-different-than-me: Can I trust them? Will they trust me? After all they are an outgroup. If we are able to rise above our fears and distrust, our needs for connection are satisfied, else we remain isolated.

World model:

Physical-World:Is the physical universe lawful? is it determined and non-miraculous? If our precepts lead us to believe that we live in a lawful universe, we have a stable overarching schema; whenever we witness something not inline with the laws of nature, that schema goes for a toss.

Social-World: Is the social world predictable? do actions of people make sense or is there too much randomness? If the social world seems predictable and lawful in its own sense, then we can maintain a coherent worldview; else if we encounter too many behaviors or events of which we cannot make sense we risk becoming incoherent.

It is my contention that dysfunctional beliefs at each of these eight sub-models lead to different types of psychopathology. For eg. the Life model that say that life is malevolent/ bleak may lead to anxiety ; a Self model claiming that the self is worthless/ incompetent may lead to depression; while a World model were events/percepts don’t make sense and is incoherent/unstable may lead to psychosis.

And of course this may be mediated by early life experiences/ genetic propensities that give rise to differences in brain neurotransmitter systems. But a detailed model about that should be the subject of a new post.
