141 Beyond the Binding Problem: Toward an Experiential Model of Nested Binding<br />
Levels to Integrate the Components of Experience James Clement Van Pelt<br />
(Initiative In Religion/Science, Yale University, New Haven, CT)<br />
If the binding of sensory components into a single sense (e.g. vision) is mysterious, an<br />
incalculably greater mystery is the means by which all the senses bind together into a unified<br />
sensory totality, i.e. the sensorium – “the array of senses, feelings, and bodily orientations”<br />
through which sentient beings experience the world and themselves. The transformation between<br />
those two binding levels – from sensory components to senses, and from senses to<br />
sensorium – implies a succession of such transformations and levels, each extended from the<br />
previous level and nested within the next. In that progression, the level beyond the binding<br />
that produces the sensorium is the occasion at which the sensorium is bound with its mental<br />
equivalent comprising memories and other associations, thoughts and concepts, and mental<br />
(not physical) sensations. The sensorium and its mental equivalent interact to produce, and<br />
are bound together with, their affective equivalent, i.e. the unified experiential sphere of emotional<br />
and other “feelings’ that are neither purely physical nor purely mental, including states<br />
sometimes called subtle for which no names may exist. The parallel processing of sensory,<br />
mental, and affective components into a unified appearance may suggests that the distinction<br />
usually made between physical/neural binding and metaphysical/ experiential binding may be<br />
false, since (for example) the binding of a shape, a color, and a texture together to present a<br />
single image requires some degree of recognition, and hence experience, to move the process<br />
to the next cognitive step. Likewise, the metaphor of a progression of levels from physical<br />
substrate to experienced appearance could be misleading, since the binding of the senses,<br />
feelings, and mental contents happens simultaneously, interactively, and in parallel such that<br />
patterns and meanings are identified along the full continuum of emerging experience. For<br />
example, the sensation of burning, the feeling of alarm, and the intention of withdrawing one’s<br />
hand from the stove are developed as discrete yet interwoven strands, allowing the protective<br />
reaction to occur prior to the final production of the integrated appearance. This may contradict<br />
the representation model of consciousness asserting that the sensorium must present its<br />
appearance prior to affective or mental responses. Certain questions present themselves. Is<br />
there a “common sense” (sensus communi) into which the discrete senses are translated, as<br />
implied by synesthesia? Is the binding process at each level partly telic, i.e. is the causal direction<br />
entirely “bottom up” or is the binding constrained by prehension of how the components<br />
are related as much as by the components themselves? How many steps altogether compose<br />
the entire binding progression? Is basic sensory binding (e.g. vision) the fundamental level in<br />
the process, or is there an even more fundamental binding prior to that? What does the experience<br />
of unbinding, by volition or fatigue, and the effort required to “hold things together”<br />
between sleep periods, indicate about the separability of experience from the experiencer?<br />
This presentation explores such issues and the first-person techniques that can be employed<br />
to trace the experiential correlates of the underlying neurology toward the development of an<br />
experiential model of the multilevel binding process. P2<br />
2.13 Emotion<br />
142 A Computational Model of Emotions: Anxiety and Fear Peter Raulefs<br />
(QIQCS, Santa Clara, CA)<br />
In studying emotions, we consider [1,2,3]: (1) The phenomenology as described by cognitive,<br />
behavioral, and physiological manifestations of emotional experiences. (2) Mental states<br />
established by neurobiological processes that relate to emotional experiences. (3) Neurobiological<br />
processes that instantiate emotional experiences. We propose a computational framework<br />
used to construct models of emotion to explain what emotions are, how they evolve,<br />
and how they result in observable manifestations. We show how such models provide testable<br />
theories of emotion, and enable simulations of emotional processes with testable predictions<br />
of behavioral responses to sensory and cognitive stimuli evoking emotions. The computational<br />
framework provides (a) Computational primitives that include an abstract state space,<br />
operators to implement state transitions, and combinators to aggregate operators into pro-
