examine an emotion episode from its elicitation to the differentiation into affective processes. An affective-conceptual spaces model is proposed as a framework for representing affective information on the conceptual level.

Keywords: surprise, affective-conceptual spaces model, affective
concepts, affective representation.

Panksepp (1998) proposed seven neural affective systems of which the SEEKING system, a generalized approach-seeking
system, motivates organisms to pursue resources needed for survival. When an organism is presented with a novel stimulus, the dopamine (DA) in the nucleus accumbens septi (NAS) is released. The DA circuit outlines the generalized mesolimbic dopamine-centered SEEKING system and is especially responsive when there is an element of unpredictability in forthcoming rewards. We propose that when the outcome of this interaction is unexpected or unanticipated then Panksepp’s “cognitive or expectancy reset” mechanism involving the cognitive dissonance would yield the subjective emotion of surprise. In order to appropriately react to the environment’s stimuli one needs fundamental processes that would enable one to distinguish between what is novel and what has been already experienced, as well as the different degrees of novelty. Novel events are those whose essential features of the representation (visceral and perceptual) are altered and being discrepant provoke more sustained attention. Novelty arises from salient and arousing events and the organism experiences surprise, as coming out of a habitual state. In this framework, we shall look at established theories of emotions and propose a different approach to their taxonomy.

Keywords: habituation, change, novelty, arousal, taxonomy of affective processes,SEEKING system.
