Humans, like other animals, are exposed to a continuous stream of signals, which dynamic, multimodal, extended, and time varying in nature. This complex input space must be transduced sampled by our sensory systems transmitted the brain where it can guide selection appropriate actions. To simplify this process, it's been suggested that exploits statistical regularities stimulus space. Tests idea have largely confined unimodal signals natural scenes. One important class multisensory for...
In the social world, multiple sensory channels are used concurrently to facilitate communication. Among human and nonhuman primates, faces voices primary means of transmitting signals (Adolphs, 2003; Ghazanfar Santos, 2004). Primates recognize correspondence between species-specific facial vocal expressions (Massaro, 1998; Logothetis, Izumi Kojima, 2004), these visual auditory can be integrated into unified percepts enhance detection discrimination. Where how such communication at neural...
X-ray analyses of macaque vocal tract movements show that monkeys’ inability to speak is not due limitations peripheral anatomy.
Marmosets learn to talk baby-talk As human infants grow, their vocalizations change from cries, babbles, words. This pattern has been presumed be absent other primates. Indeed, the development of bird song is often regarded as a closer approximation language development. Takahashi et al. , however, observed that marmoset cries and calls in first 2 months after birth mature much same way they do humans (see Perspective by Margoliash Tchernichovski). Calls changed infants' vocal structures...
Multiple neuron ensemble recordings were obtained simultaneously from both the primary somatosensory (SI) cortex and ventroposterior medial thalamus (VPM) before during combined administration of reversible inactivation SI a subcutaneous block peripheral trigeminal nerve fibers. This procedure was performed to quantify contribution descending corticofugal projections on ( i ) normal organization thalamic receptive fields ii plastic reorganization that immediately follows deafferentation....
The existence of multiple nodes in the cortical network that integrate faces and voices suggests they may be interacting influencing each other during communication. To test hypothesis multisensory responses auditory cortex are influenced by visual inputs from superior temporal sulcus (STS), an association area, we recorded local field potentials single neurons both structures concurrently monkeys. functional interactions between STS, as measured spectral analyses, increased strength...
Vocal-tract resonances (or formants) are acoustic signatures in the voice and related to shape length of vocal tract. Formants play an important role human communication, helping us not only distinguish several different speech sounds [1], but also extract information physical characteristics speaker, so-called indexical cues. How did formants come such communication? One hypothesis suggests that ancestral formant perception--a might be present extant nonhuman primates--was provide cues...
Very realistic human-looking robots or computer avatars tend to elicit negative feelings in human observers. This phenomenon is known as the "uncanny valley" response. It hypothesized that this uncanny feeling because synthetic characters concept of "human," but fail live up it. That is, failure generates unease due character traits falling outside expected spectrum everyday social experience. These unsettling emotions are thought have an evolutionary origin, tests hypothesis not been...
Between 6 and 10 months of age, infants become better at discriminating among native voices human faces worse nonnative other species’ faces. We tested whether these unisensory perceptual narrowing effects reflect a general ontogenetic feature systems by testing across sensory modalities. showed pairs monkey producing two different vocalizations to 4-, 6-, 8-, 10-month-old asked they would prefer look the corresponding face when heard one vocalizations. Only youngest groups exhibited...
In humans, vocal turn-taking is a ubiquitous form of social interaction. It communication system that exhibits the properties dynamical system: two individuals become coupled to each other via acoustic exchanges and mutually affect other. Human develops during first year life. We investigated development in infant marmoset monkeys, New World species whose adult behaviour same universal features human turn-taking. find infants undergo trajectory change for as do so life-history stage.
