Cross-cultural differences in maternal perceptions of cries of low- and high-risk infants

The tape-recorded cries of low- and high-risk newborn infants were rated by 150 inner-city Anglo-American, Black-American, and Cuban-American mothers during the hospital lying-in period following childbirth. Half of each cultural group was primiparous and half was multiparous. The mothers rated the cries along 4 perceptual and 6 caregiving response scale items. Reliable differences were found between low- and high-risk infant cries on all perceptual responses with the effects of culture and parental experience affecting the degree of differences. Generally, Anglo-American mothers found the cries more distressing, urgent, arousing, and sick sounding than Black-American mothers, while Cuban-American mothers showed similarities to both Black- and Anglo-American mothers depending on the scale items. The ratings on the caregiving response scale items paralleled cultural differences found on the perception scale items and previous reports of the mother-infant interaction patterns of other Anglo-, Black-, and Cuban-American samples. The results are discussed as being important in developing nonethnocentric views of the functional significance of the behaviors of the infant at risk, yet as providing evidence of the cross-cultural significance of the cry sound of the infant at risk.     

Acoustic Characteristics of Naturally Occurring Cries of Infants with "Colic"

Although infantile colic has long been defined by a perceived excessive amount of crying, acoustic attributes of the cry sound may also contribute to perceptions that this early social behavior is excessive or problematic. From an original sample of 76 infants (38 infants referred to physicians for problematic crying, or "colic," and 38 pair-matched comparison infants), 48 infants who produced naturally occurring cry bouts both before and after an evening feeding were studied: 11 infants with Wessel's colic, 15 infants with non-Wessel's colic, and 22 comparison infants. Standard and vociferous cry segments were selected from up to 2 min of tape-recorded crying for spectrum analysis. Vociferous cry segments had a longer duration, a higher fundamental frequency, and a greater percentage of dysphonation than did standard segments. No differences between infant groups were found in cries before feeding. After feeding, infants who were problematic criers, independent of Wessel's criteria, showed a greater percentage of dysphonation in the vociferous cry segment than did comparison infants. This finding resulted from a decrease in dysphonation in the cries of comparison infants after feeding and an increase in those of infants with non-Wessel's colic. The dominant frequency also increased after feeding in the vociferous cries of infants with Wessel's colic, resulting in these infants having higher-pitched cries after feeding than infants in the other 2 groups. Results indicate that infants who are perceived to have problematic crying have objectively different acoustic features in their cry sounds that are particularly aversive, and that complaints about excessive crying cannot be accounted for simply on the basis of reporting bias in overly concerned or emotionally labile parents.     

The effects of within-group and between-group methodologies in the study of perceptions of infant crying

Recent studies have indicated that various infant cry patterns can be reliably distinguished when directly compared with other infant cry patterns. The purpose of this study was to compare the effects of this within-group method of cry presentation (in which listeners are exposed to 2 types of cry patterns) with the effects of a between-group methodology (in which listeners are exposed to only 1 type of infant cry pattern). 4 groups of adult listeners rated the tape-recorded cries of low- and high-risk infants on 4 Likert-type scale items during experimental phases. In phase 1, subjects were exposed to either the cries of low-risk or high-risk infants but not both. In phase 2, subjects were exposed to both low-risk and high-risk infant cries. In phase 3, subjects were exposed to the cries they heard in phase 1. Whereas all scale items differentiated the low- and high-risk infant cries during the within-group analyses of phase 2, all scale items did not differentiate low- and high-risk infant cries during the between-group phase of the experiment. The specific pattern of results indicate that within-group methods of cry presentation accentuate the perceptual distance among cry types and may actually create many reliable differences that would not be found in between-group comparisons.     

Chinese Business Process Re-engineering

The popularity of business process re-engineering (BPR) and its international diffusion from the United States make it important to understand the influence of cultural factors on this concept. The global economic prominence of the Chinese and their distinctive cultural characteristics prompted our study of Chinese business process re-engineering. This article addresses a large gap in the Chinese management literature and is intended to help those who are managing organizations or marketing information technology (IT) products and related services in Greater China. We systematically compare IT-enabled change in the American and Chinese business cultures. Informal planning and process modelling, highly interdependent social and organizational relationships with ingrained hierarchies, and the prevailing attitudes towards information management and organizational change will shape the preparation for IT-enabled process innovation efforts as well as the design and implementation of IT-enhanced business process models in Chinese organizations.     

Psychophysiological and perceptual responses to infant cries varying in pitch: comparison of adults with low and high scores on the Child Abuse Potential Inventory.

Based on their scores on the Child Abuse Potential (CAP) Inventory, 30 nonparent adults were classified as either having high CAP scores (n = 15) or low CAP scores (n = 15). Subjects' heart rate and skin conductance were assessed as they listened to audio-taped presentations of four "normal" phonated infant cries and four high-pitched, hyperphonated infant cries. Subjects also rated the cries on several perceptual items. Results showed that both groups of subjects found hyperphonated cries more aversive, distressing, urgent, arousing, and sick than phonated cry sounds. Similarly, all listeners' showed higher skin conductance levels (SCL) in response to hyperphonated than phonated cries. SCL became attenuated over time in response to phonated, but not hyperphonated, cries. Adults in the high-CAP group, showed marginally higher heart rates than low-CAP adults following presentation of all infant cry sounds and responded to phonated cries with marginally higher skin conductance levels than low-CAP adults. The responses of high-CAP nonparent adults are similar to those of parents with histories of physically abusive interactions with their infants.     

Adult perceptions of pain and hunger cries: a synchrony of arousal

180 male and female nonparent adults rated tape-recordings of the initial, middle, and final 10-sec segments of pain and hunger cries on 4 7-point Likert-type scale items describing how urgent, arousing, aversive, and sick the cry segments sounded. Multivariate analyses of variance showed that the final segment of the pain cry was perceived as less urgent, arousing, and aversive than the initial and middle segments. The hunger cry was perceived as increasingly more urgent, arousing, and aversive from the initial to the middle to the final cry segments, with the final segment receiving higher ratings than the final segment of the pain cry. The middle segment of both cries was the most sick sounding. While females were more aroused than males as the hunger cry intensified, and females were less aroused than males as the pain cry subsided, the initial segments of the pain cry were particularly potent stimuli to both males and females. These results suggest that different segments of cries resulting from the same stimulus provide different messages that communicate the presumed level of infant arousal.
