Rolls defines emotion as innate reward and punishment. This could not explain our results showing that people learn faster in a negative mood. We argue that what people know about their world affects their emotional state. Negative emotion signals a failure to predict negative reward and hence prompts learning to resolve the ignorance. Thus what you don't know affects how you feel.

Given that Pickering & Garrod's (P&G's) account integrates language production and comprehension, it is reasonable to ask whether it is compatible with embodied cognition. I argue that its dependence on rich intermediate representations of linguistic structure excludes embodiment. Two options are available to supporters of embodied cognition: They can adopt a more liberal notion of embodiment or they can attempt to replace these intermediate representations with robustly embodied ones. Both of these options face challenges.

We agree with Lake et al.'s trenchant analysis of deep learning systems, including that they are highly brittle and that they need vastly more examples than do people. We also agree that human cognition relies heavily on structured relational representations. However, we differ in our analysis of human cognitive processing. We argue that (1) analogical comparison processes are central to human cognition; and (2) intuitive physical knowledge is captured by qualitative representations, rather than quantitative simulations.

The Newell Test as it is proposed by Anderson & Lebiere (A&L) has the disadvantage of being too positivistic, stressing areas a theory should cover, instead of attempting to exclude false predictions. Nevertheless, Newell's list can be used as the basis for a more stringent test with a stress on the falsifiability of the theory.

Some neurotropic enteroviruses hijack Trojan horse/raft commensal gut bacteria to render devastating biomimicking cryptic attacks on human/animal hosts. Such virus-microbe interactions manipulate hosts’ gut-brain axes with accompanying infection-cycle-optimizing central nervous system (CNS) disturbances, including severe neurodevelopmental, neuromotor, and neuropsychiatric conditions. Co-opted bacteria thus indirectly influence host health, development, behavior, and mind as possible “fair-weather-friend” symbionts, switching from commensal to context-dependent pathogen-like strategies benefiting gut-bacteria fitness.

The SIMS model offers an embodied perspective to cognition and behaviour that can be applied to organizational studies. This model enriches behavioural and brain research conducted by social scientists on emotional work (also known as emotional labour) by including the key role played by body-related aspects in interpersonal exchanges. Nevertheless, one could also study a more vocal aspect to smiling as illustrated by the development of “smile down the phone” strategies in organizations. We propose to gather face-to-face and voice-to-voice interactions in an embodied perspective taking into account Lakoff and Johnson's (1980) theory of conceptual metaphors.

Our model of haptic object recognition points to the importance of material, as well as geometric properties of objects. Collectively, these can elicit a recognition response after an initial contact, without sequential exploration. This model suggests a revision of the authors' proposals, which takes into account an individual's intention – whether it is for perception or action – and the extent of exploratory movement.

Van Gelder has presented a position that he ties closely to a broad class of models known as dynamical models. One can support many of his broader claims about the importance of this class (as has been argued by connectionists for quite some time), but there are a number of unique characteristics of his brand of dynamicism. These characteristics engender difficulties for his view.

Intradermal capsaicin in humans causes pain, primary hyperalgesia, and secondary mechanical hyperalgesia and allodynia. Parallel changes occur in the responses of primate spinothalamic tract cells and in rat behavior. Neurotransmitters that trigger secondary mechanical hyperalgesia and allodynia include excitatory amino acids and substance P. Secondary mechanical allodynia is actively maintained by central mechanisms. Our group has investigated mechanisms of central sensitization of nociceptive neurons by examining the responses to intradermal injection of capsaicin. These experiments are pertinent to issues raised by coderre & katz (sect. 2).

Pessoa's (2013) arguments imply that various leading approaches in the social sciences have not adequately conceptualized how emotion and cognition influence human decision making and social behavior. This is particularly unfortunate, as these approaches have been central to the efforts to build bridges between neuroscience and the social sciences. We argue that it would be better to base these efforts on other social theories that appear more compatible with Pessoa's analysis of the brain.

Grodzinsky's Tree-Pruning Hypothesis can be extended to explain agrammatic comprehension disorders. Although agrammatism is evidence for syntactic modularity, there is no evidence for its anatomical modularity or for its localization in the frontal lobe. Agrammatism results from diffuse left hemisphere damage – allowing the emergence of the limited right hemisphere linguistic competence – rather than from damage to an anatomic module in the left hemisphere.

Wegner's tactic of describing the conscious mind as if it inhabited a Cartesian Theater in the brain is a stopgap solution that needs to be redeemed by paying off these loans of comprehension. Just how does Wegner propose to recast his points?
