The topics treated in The brain and emotion include the definition, nature, and functions of emotion (Ch. 3); the neural bases of emotion (Ch. 4); reward, punishment, and emotion in brain design (Ch. 10); a theory of consciousness and its application to understanding emotion and pleasure (Ch. 9); and neural networks and emotion-related learning (Appendix). The approach is that emotions can be considered as states elicited by reinforcers (rewards and punishers). This approach helps with understanding the functions of emotion, with (...) classifying different emotions, and in understanding what information-processing systems in the brain are involved in emotion, and how they are involved. The hypothesis is developed that brains are designed around reward-and punishment-evaluation systems, because this is the way that genes can build a complex system that will produce appropriate but flexible behavior to increase fitness (Ch. 10). By specifying goals rather than particular behavioral patterns of responses, genes leave much more open the possible behavioral strategies that might be required to increase fitness. The importance of reward and punishment systems in brain design also provides a basis for understanding the brain mechanisms of motivation, as described in Chapters 2 for appetite and feeding, 5 for brain-stimulation reward, 6 for addiction, 7 for thirst, and 8 for sexual behavior. Key Words: amygdala; brain evolution; consciousness; dopamine; emotion; hunger; orbitofrontal cortex; punishment; reward; taste. (shrink)

Rolls shares important data on hunger, thirst, sexuality, and learned behaviors, but is it pertinent to understanding the fundamental nature of emotionality? Important as such work is for understanding the motivated behaviors of animals, Rolls builds a constructivist theory of emotions and primary-process affective consciousness without considering past evidence on specific types of emotional tendencies and their diverse neural substrates.

The article presents two studies based on the assumption that the effectiveness of cognitive control depends on the subject’s type of emotional state. Inhibitory control is taken into account, as the basic determinant of the antisaccade reactions and the emotional Stroop effect. The studies deal with differentiation of emotions on the basis of their origin: automatic vs. reflective. According to the main assumption, automatic emotions are diffusive, and decrease the effectiveness of cognitive control. The hypothesis predicted that performance level of (...) both the Antisaccade Task and the Emotional Stroop Test would be lower in the automaticemotion eliciting condition than in the reflective-emotion eliciting condition. In two experimental studies, positive and negative emotions were elicited. The results support the predictions, regardless of the valence of emotions. (shrink)

Certain emotional processes “bypass the will” and even awareness, whereas others arise due to the deliberative evaluation of objects, states, and events. It is important to differentiate between the automatic versus reflective origins of emotional processes, and sensory versus conceptual bases of diverse negative and positive emotions. A taxonomy of emotions based on different origins is presented. This taxonomy distinguishes between negative and positive automatic versus reflective emotions. The automatic emotions are connected with the (a) homeostatic and (b) hedonistic regulatory (...) mechanisms. The reflective emotions—uniquely human—are described in reference to deliberative processes and appraisals based on two types of conceptual and verbalized evaluative standards: (a) ideal self-standards and (b) general, axiological standards of good and evil.
