The proposed dynamic systems model of emotion generation indeed appears considerably more plausible and descriptively adequate than traditional linear models. It also comes much closer to the complex interactions observed in neurobiological research. The proposals regarding self-organization in emerging appraisal-emotion interactions are thought-provoking and attractive. Yet, at this point they are more in the nature of promises than findings, and are clearly in need of corroborating psychological evidence or demonstrated theoretical desirability.

A functional interpretation of facial expressions of pain is welcome. Facial expressions of pain may be useful not only for communication, such as inviting help. They may also be of direct use, as parts of writhing pain behavior patterns, serving to get rid of pain stimuli and/or to suppress pain sensations by something akin to hyperstimulation analgesia.

The book contains a masterly review of Rolls's single-neuron research reflecting rewards. It places that research in the context of the neo-behaviorist theory of emotions. That theory provides a useful first approximation to emotion-eliciting conditions but has little to tell about emotions as motivational states or response dispositions: nor does it give a rationale for what are considered to be primary rewarding stimuli.

What are 'emotions'? This book offers a balanced survey of facts and theory.
