Enhanced cognitive processing by viewing snakes in children with autism spectrum disorder. A preliminary study
There were possible odd color-specific effects in children with ASD when images were presented to the children in green. Implications of the findings are argued with respect to active avoidance or attraction as one of the behavioral characteristics commonly noted in children with ASD
Male replacement and stability of territorial boundary in a group of agile gibbons (Hylobates agilis agilis) in West Sumatra, Indonesia
Soprano singing in gibbons
Diversifications in primate vocalization, including human speech, are believed to reflect evolutionary modifications in vocal anatomy and physiology. Gibbon song is acoustically unique, comprising loud, melodious, penetrating pure tone‐like calls. In a white‐handed gibbon, Hylobates lar , the fundamental frequency ( f 0 ) of song sounds is amplified distinctively from the higher harmonics in normal air. In a helium‐enriched atmosphere, f 0 does n…
Neural Correlates for Numerical Processing in the Manual Mode
This paper reports a study designed to examine the neuronal correlates for comprehending the signs of American Sign Language representing numerals in deaf signers who acquired Japanese Sign Language as their first language. The participants were scanned by functional magnetic resonance imaging (fMRI) twice on the day of the experiment. The results of the measurements revealed that upon learning that the signs actually have numeric meaning, a netw…
Differences in Arithmetic Subtraction of Nonsymbolic Numerosities by Deaf and Hearing Adults
Previous research has demonstrated that both hearing adults and hearing children with no training in arithmetic successfully performed approximate arithmetic on large sets of elements. Here, the possibility is explored that the same phenomenon can be confirmed in deaf adults who have acquired a signed language as their first language. Results reveal that they can perform simple arithmetic subtraction on nonsymbolic numerosities. Their performance…
Pitch modification when interacting with elders
Twenty Japanese-speaking twenty-six- to twenty-seven-year-old women were recorded as they conversed with an infant, an elder, or another young adult. When their utterances were acoustically compared among the three settings with regard to prosodic characteristics, elevated pitch and increased pitch range were found when their speech was directed to both the infant and the elder as compared to when it was directed to the young adult. The degree to…
A variable that may affect individual differences in the child‐directed speech of Japanese women
Sixty‐one single Japanese‐speaking women between the ages of 18 and 26 years were recorded as they read aloud picture books to a young child and as they conversed with another Japanese‐speaking woman. When their utterances were acoustically compared between the two settings with regard to prosodic features, both the average pitch and pitch excursions exhibited a significant increase when interacting with the child in 17 of the 61 women. In 36 of …
Preference for infant-directed singing in 2-day-old hearing infants of deaf parents
L. J. Trainor (1996) reported preferences for infant-directed versus infant-absent singing in English in 4-7-month-old hearing infants of English-speaking hearing parents. In this experiment, the author tested preferences for infant-directed singing versus adult-directed singing in 15 two-day-old hearing infants of deaf parents for a Japanese and an English play song. Using a modified visual-fixation-based auditory-preference procedure, the autho…
Perception of motherese in a signed language by 6-month-old deaf infants
The study explored the possibility that characteristics in perception of speech sounds found in preverbal hearing infants might extend to perception of signed languages in congenitally deaf infants during the same period. Participants were deaf mothers (N = 17) and their deaf infants; 5 of the dyads were used to prepare the stimulus tape later shown to the remaining 12 dyads. To develop the tape, the 5 mothers were observed when reciting identica…
The relation between index-finger extension and the acoustic quality of cooing in three-month-old infants
Fourteen full-term, healthy, three-month-old infants were observed during a total of 15 minutes spontaneous face-to-face interaction with their mothers. Facial and manual actions, gaze direction and vocalizations were coded. The infants' cooing vocalizations were categorized into syllabic and vocalic sounds. Index-finger extension occurred frequently in sequence with syllabic sounds, which are speech-like vocalizations, but rarely occurred in seq…
Vocal communication of tonkean macaques in confined environments
Effects of contingent and noncontingent maternal stimulation on the vocal behaviour of three- to four-month-old Japanese infants
A total of 48 male infants experienced either conversational turn-taking or random responsiveness of their mothers when aged 0;3 and 0;4. In both periods, the infant's rate of vocalizing was not significantly influenced by the contingency of the mother's response, but contingency altered the temporal parameters of the infant's vocal pattern. Infants tended to produce more bursts or packets of vocalizations when the mother talked to the infant in …
Pitch characteristics of Japanese maternal speech to infants
The fundamental frequency F 0 patterns of maternal speech addressed to infants aged 0;3–0;4 were measured quantitatively. Speech samples were recorded when six Japanese-speaking mothers addressed an adult and their own infants. Japanese mothers speaking to adults use a relatively restricted F 0 range, concentrated around the mother's F 0 , which tends to be near the low end of the total range used. These acoustic characteristics are not altered s…
Cortisol Level and Acoustic Features of Cries in Japanese Newborns
The present study was conducted to evaluate cry features and cortisol level in 10 healthy, full-term male newborns. For each of them, a total of 10 10-min vocal recording sessions were undertaken when spontaneous crying was displayed. Simultaneously saliva was collected from the subject. The results indicated that the duration of cries and the amount of dysphonation in cries were highly correlated with cortisol level in every infant. When the cor…
Effect of separation distance on isolation call structure in squirrel monkeys ( Saimiri sciureus )
Isolation calls of captive squirrel monkeys were recorded by separating infants from their natal group members and then permitting vocal contact between the “lost” baby and the group at systematically varied distances. Separated infants gave longer calls at greater separation distances from their natal group members, and responding adults and juveniles similarly extended the length of their vocalizations. In the longer variants, a highfrequency e…
Categorical responses to natural and synthesized alarm calls in Goeldi's monkeys (Callimico goeldii)
Psycholinguistic analyses of alarm calls of Japanese monkeys ( Macaca fuscata fuscata )
Alarm and estrous calls emitted by Japanese macaques were recorded and analyzed in the Arashiyama West and East groups. Their responses to natural calls as well as to synthesized versions varying in the acoustic parameters that defined the vocalizations were studied. The response patterns shown by Arashiyama West group members, which were subject to a distinct change with only a slight difference of a single parameter, appeared to reflect strict …
