Abstract:
The "somatic marker mechanism" (SMM; Damasio 1994) is proposed as the cognitive and neural basis of the theory of mind mechanism. The SMM evolved for evaluating the intentions, dispositions, and relationships of conspecifics; hence, it is adaptive in the social domain. It is predicted that chimpanzees will indeed have theory of mind (ToM) ability, but that this will be socially domain-specific. Domain-general ToM will be found only in primates with abstract, symbolic language (adult humans). Putative ToM tests require revision in the light of these distinctions.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
