Zinacantec Family Homesign is a new sign language emerging spontaneously over the past three decades in a single family in a remote Mayan Indian village. Three deaf siblings, their Tzotzil-speaking age-mates, and now their children, who have had contact with no other deaf people, represent the first generation of Z signers. I postulate an augmented grammaticalization path, beginning with the adoption of a Tzotzil cospeech holophrastic gesture—meaning “come!”—into Z, and then its apparent stylization as an attention-getting sign, followed by grammatical (...) regimentation and pragmatic generalization as an utterance initial change of speaker or turn marker.

This paper introduces a manual movement performed recurrently by German children in the age range of four to six. Based on the movement gestalt and its meaning, we termed it the Slapping movement. All forms identified in the data were performed with a communicative function, yet they showed different degrees of “gesturality.” To be more precise, we observed versions that clearly count as actions or gestures, but we also observed transitional forms between them. Based on a thorough analyses of form, (...) meaning, and context we determined variations of the Slapping gesture that showed different degrees of abstraction from action to gesture in a semiotic sense. These degrees are distinguished by modifications in the execution of the movement and different levels of form stability, environmental coupling, and representational complexity. (shrink)

Pointing is a cornerstone of human communication, but does it take the same form in all cultures? Manual pointing with the index finger appears to be used universally, and it is often assumed to be universally preferred over other forms. Non-manual pointing with the head and face has also been widely attested, but it is usually considered of marginal significance, both empirically and theoretically. Here, we challenge this assumed marginality. Using a novel communication task, we investigated pointing preferences in the (...) Yupno of Papua New Guinea and in U.S. undergraduates. Speakers in both groups pointed at similar rates, but form preferences differed starkly: The Yupno participants used non-manual pointing numerically more often than manual pointing, whereas the U.S. participants stuck unwaveringly to index-finger pointing. The findings raise questions about why groups differ in their pointing preferences and, more broadly, about why humans communicate in the ways they do. (shrink)
