“…These findings support the position that pointing with the index finger is a milestone in social-cognitive development (Liszkowski & Tomasello, 2011) and the development of conventional communication (Leung & Rheingold, 1981). The index finger shape of pointing thus reflects advances in the child's communication and readiness for successful language acquisition which in turn results in better linguistic skills.…”

“…The predictive value of the index finger shape compared to whole-hand pointing has remained understudied, but there is some indication that index finger pointing involves more complex communicative skills compared to whole-hand pointing. For example, whole-hand pointing emerges earlier in ontogeny (Lock, Young, Service, & Chandler, 1990), presents a nonconventionalized form of communication (Leung & Rheingold, 1981), and is shared with other nonhuman primates (Leavens & Hopkins, 1999). Furthermore, 12-month-olds who point with their index finger-compared to infants who only point with the whole hand-understand communicative intentions better, point more frequently, and accompany their pointing more often by communicative vocalizations (Liszkowski & Tomasello, 2011).…”

In Infants' Hands: Identification of Preverbal Infants at Risk for Primary Language Delay

et al. 2016

Early identification of primary language delay is crucial to implement effective prevention programs. Available screening instruments are based on parents' reports and have only insufficient predictive validity. This study employed observational measures of preverbal infants' gestural communication to test its predictive validity for identifying later language delays. Pointing behavior of fifty-nine 12-month-old infants was analyzed and related to their language skills 1 year later. Results confirm predictive validity of preverbal communication for language skills with the hand shape of pointing being superior compared to the underlying motives for pointing (imperative vs. declarative). Twelve-month-olds who pointed only with their open hand but never with their index finger were at risk for primary language delay at 2 years of age.

“…Moreover, during this time, the proportion of unreciprocated eye gaze makes up 94.02% of the total amount of the mother's eye gaze directed towards Eva. Although we do expect that with increased mobility Eva starts to explore the environment (Leung & Rheingold, 1981;Adamson, 1995;Swisher, 1992), we also expect the dyad to be able to 'coordinate or systematically divide attention between objects and social partners' which would allow mother and child 'to establish a joint focus on an object or event while also allowing the infant to receive communicative information produced by the mother' (Waxman & Spencer, 1997: 105). However, this is not the case for Eva and Sophia.…”

The language development of a deaf child with a cochlear implant

et al. 2013

Hearing parents of deaf or partially deaf infants are confronted with the complex question of communication with their child. This question is complicated further by conflicting advice on how to address the child: in spoken language only, in spoken language supported by signs, or in signed language. This paper studies the linguistic environment created by one such mother (language input and parental behaviour) and her child's language production longitudinally during the first two years of life of the infant to discover possible relationships. The mother-child dyad was observed when the child was seven, nine, twelve, eighteen, and twenty-four months old. Changes in the mother's approach to communication with her child and their consequent effects on the child's language development will be highlighted. The infant concerned has a hearing loss of more than 90dB on both ears, which qualified her for cochlear implantation. At the age of ten months she was implanted on her left side (30/04/2010). Five months later she received a second implant (24/09/2010). By means of several assessments instruments the created linguistic environment, the language development of the infant in question and possible causal relationships were investigated before and after implantation. These instruments include: Pragmatics Profile of Everyday Communication; Profile of Actual Linguistic Skills; video-images of interaction analysed in ELAN; MacArthur-Bates Communicative Development Inventory for spoken Dutch and Flemish Sign Language (from nine months onwards). Results for each individual assessment moment are given as well as an overarching interpretation of evolution in the language development. The child seems to be profiting from a bimodal/bilingual approach to communication up to nine months of age. She is progressing considerably in both spoken Dutch and Flemish Sign Language, with a possible onset of functional code-switch. However, a setback is evidenced in the child's language development, mirrored in a setback in the mother's sensitive behaviour as she moves to a more monolingual approach after cochlear implantation. Highlights: This paper presents a study of communication between hearing mother and deaf child.  This will be done longitudinally before and after cochlear implantation (CI).  Benefit from bimodal/bilingual approach is apparent up to 0;9 before CI.  After CI (0;10) there seems to be a setback in linguistic behaviour of the dyad.

People use gestures to give verbal communication more expression and also to replace the speech. One of the most concise and expressive gestures is the pointing gesture. Pointing gesture can be observed in the early childhood. In these early years, it is used to point at objects or people. Later, people use pointing gestures even for more complex things such as to visualize directions. Increasing pointing gestures are also used for interacting with computers. For example, gestures can be used to remotely interact with a display, without using an input tool. In this work we investigated how people point to objects and how the recognition accuracy can be improved by using a gesture recognition system. We performed a user study, where participants had to point on projected pointing targets. These gestures were recorded as reference data with the help of motion capture system. We used a variety of starting positions in which the study was carried out. For this the participants were placed with a distance of 2 to 3 meters to the pointing targets. At these two positions the participants had to sit and stand while pointing to the targets. From the recorded reference data we derived a pointing vector. Each vector describes the direction in which the gesture is directed. We generate these vectors out of different body parts. This is done to show that there are different ways to create these vectors but they behave all the same. In the optimal case, this vector would describe the path of the person pointing to the object, in this case, the projected point. By mathematical analyzes we show that in average over several experiments and over several participants a systematic deviation from this optimal vector can be detected. We specify models, which can compensate the systematic deviation. These models shift the pointing vector in the direction of the average distance between optimum and average study vector. Products of the consumer market can be used to detect pointing gestures. There gestures can be improved with the generated models. The focus here is, for example, products like the Kinect.
