Efforts to bridge emotion theory with neurobiology can be facilitated by dynamic systems (DS) modeling. DS principles stipulate higher-order wholes emerging from lower-order constituents through bidirectional causal processes – offering a common language for psychological and neurobiological models. After identifying some limitations of mainstream emotion theory, I apply DS principles to emotion–cognition relations. I then present a psychological model based on this reconceptualization, identifying trigger, self-amplification, and self-stabilization phases of emotion-appraisal states, leading to consolidating traits. The article goes on to describe neural structures and functions involved in appraisal and emotion, as well as DS mechanisms of integration by which they interact. These mechanisms include nested feedback interactions, global effects of neuromodulation, vertical integration, action-monitoring, and synaptic plasticity, and they are modeled in terms of both functional integration and temporal synchronization. I end by elaborating the psychological model of emotion–appraisal states with reference to neural processes. Key Words: appraisal; bidirectional causality; cognition; dynamic systems; emotion; neurobiology; part–whole relations; self-organization.

The aim of appraisal theory in the psychology of emotion is to identify the features of the emotion-eliciting situation that lead to the production of one emotion rather than another². A model of emotional appraisal takes the form of a set of dimensions against which potentially emotion-eliciting situations are assessed. The dimensions of the emotion hyperspace might include, for example, whether the eliciting situation fulfills or frustrates the subject’s goals or whether an actor in the eliciting situation has violated a norm. Richard Lazarus’s well-known model of emotional appraisal has six dimensions, and the regions of the resulting hyperspace that correspond to particular emotions are summarized by Lazarus as the ‘core relational themes’ of those emotions. Anger, for examples, is elicited by the core relational theme ‘a demeaning offence against me and mine’, sadness by ‘having experienced an irrevocable loss’ and guilt by ‘having transgressed a moral imperative’ (Lazarus, 1991).

Emotional appraisal happens at more than one level. Low-level appraisals involve representations that are semantically coarse-grained, fuse the functional roles of belief and desire and have impoverished inferential roles, making it best to think of them as sub-conceptual. Multi-level theories of emotional appraisal are thus best conceived, not as theories of the actual conceptual content of emotional appraisals, but as ecological theories that identify the aspects of the environment that appraisal processes are tracking using diverse cognitive means. These aspects of the environment are what the environment ‘affords’ the organism. Some of these affordances are ‘goal-affordances’ - possibilities for future action. This perspective on emotional appraisal lends support to the idea that emotional appraisal is in part ‘Machiavellian’ or ‘strategic’. Organisms take into account the payoffs resulting from an emotional response when determining whether the eliciting situation ‘warrants’ that emotion.

Appraisal theories of emotion generally presuppose that emotions are “directed at” various items. They also hold that emotions have motivational properties. However, although it coheres well with their views, they have yet to seriously develop the idea that the function of emotional direction is to guide those properties. I argue that this “guidance hypothesis” can open up a promising new field of research in emotion theory. But I also argue that before appraisal theorists can take full advantage of it, they must drop their further assumption that to determine an emotion's direction, one need only retrace the process that caused it. Contrary to this “retracing view,” I argue for an “independence thesis”: directed emotions are produced by two functionally independent sub-processes. The first, “affect-causation,” functions in part to produce a state with certain motivational properties given certain representations. The second, “affect-direction,” has the function of optimally guiding those motivational properties by associating them with representations that may properly be quite dissimilar from the causal ones. By provisionally adopting the independence thesis and empirically testing the guidance hypothesis, I argue that appraisal theorists stand a good chance of significantly increasing the explanatory power of their theories.

This commentary makes three points: (1) There may be no clear-cut distinction between emotion and appraisal “constituents” at neural and psychological levels. (2) The microdevelopment of an emotional interpretation contains a complex microdevelopment of affect. (3) Neurophenomenology is a promising research program for testing Lewis's hypotheses about the neurodynamics of emotion-appraisal amalgams.

Considered in relation to the component brain systems of appraisal-emotion interactions, dynamical systems theory blurs the divisions that seem obvious in a psychological analysis, such as between arousal, emotion, and appraisal. At the same time, the component brain mechanisms can themselves be seen to be incomplete as units of analysis, making sense only in the context of the whole organism.

Emotion theories in present philosophical discussion propose different models of relationship between feeling and appraisal. The multicomponent model considers appraisal as separate component and distinguishes it from feeling and physiological body changes thus presupposing what may be called 'disembodied' and 'disembedded' appraisal as representational. The recently emerged concept of enactment, in contrast, argues that appraisal is closely linked to feeling and physiological body changes presupposing what can be called 'embodied' and 'embedded' appraisal as relational. The aim of the paper is to investigate which concept of appraisal, the 'disembedded' or the 'embedded' one, is better compatible with current neuroimaging data on emotion processing and thus neurophilosophically more tenable. The 'disembodied' and 'disembedded' concept implies distinct and independent brain regions underlying feeling and appraisal whereas 'embodied' and 'embedded' appraisal implies overlapping and dependent brain regions. Recent neuroimaging studies demonstrate that medial and lateral prefrontal cortical regions are involved in both feeling and appraisal and that there seems to be reciprocal modulation between these regions. Though preliminary, these data suggest that feeling and appraisal are associated with different patterns of neural activity across overlapping and interdependent brain regions. I therefore conclude that current neuroscientific evidence is rather in favor of the 'embodied' and 'embedded' concept of appraisal as relational than the one of 'disembodied' and 'disembedded' appraisal as representational that is presupposed in current multicomponent theories of emotions.

The issues addressed in this commentary include: (1) the appropriate conceptualization of “appraisal”; (2) the nature and unfolding of emotional episodes over time; (3) the interrelationships between the dynamic elements of the appraisal process and their effects on other emotion components, as well as repercussions on ongoing appraisal in a recursive process; and (4) the use of brain research to constrain and inform models of emotion.

For many years, emotion theory has been characterized by a dichotomy between the head and the body. In the golden years of cognitivism, during the 1960s and ’70s, emotion theory focused on the cognitive antecedents of emotion, the so-called “appraisal processes.” Some saw bodily events largely as by-products of cognition, and as too unspecifi c to contribute to the variety of emotion experience. Cognition was conceptualized as an abstract, intellectual, “heady” process separate from bodily events. Although current emotion theory has moved beyond this disembodied stance by conceiving of emotions as involving both cognitive processes (e.g., perception, attention, and evaluation) and bodily events (e.g., arousal, behavior, and facial expressions), the legacy of cognitivism persists in the tendency to treat cognitive and bodily events as separate constituents of emotion.

Although current emotion theory has moved beyond this disembodied stance by conceiving of emotions as involving both cognitive processes (perception, attention, and evaluation) and bodily events (arousal, behavior, and facial expressions), the legacy of cognitivism persists in the tendency to treat cognitive and bodily events as separate constituents of emotion. Thus the cognitive aspects of emotion are supposedly distinct and separate from the bodily ones. This separation indicates that cognitivism’s disembodied conception of cognition continues to shape the way emotion theorists conceptualize emotion.
