Infants' Perception of Intonation: Is It a Statement or a Question?

The ability to distinguish phonetic variations in speech that are relevant to meaning is essential for infants' language development. Previous studies into the acquisition of prosodic categories have focused on lexical stress, lexical pitch accent, or lexical tone. However, very little is known about the developmental course of infants' perception of linguistic intonation. In this study, we investigate infants' perception of the correlates of the statement/yes–no question contrast in a language that marks this sentence type distinction only by prosodic means, European Portuguese (EP). Using a modified version of the visual habituation paradigm, EP‐learning infants at 5–6 and 8–9 months were able to successfully discriminate segmentally varied, single‐prosodic word intonational phrases presented with statement or yes–no question intonation, demonstrating that they are sensitive to the prosodic cues marking this distinction as early as 5 months and maintain this sensitivity throughout the first year. These results suggest the presence of precocious discrimination abilities for intonation across segmental variation, similarly to previous reports for lexical pitch accent, but unlike previous findings for word stress.     

Personality at Face Value: Facial Appearance Predicts Self and Other Personality Judgments among Strangers and Spouses

Character judgments, based on facial appearance, impact both perceivers’ and targets’ interpersonal decisions and behaviors. Nonetheless, the resilience of such effects in the face of longer acquaintanceship duration is yet to be determined. To address this question, we had 51 elderly long-term married couples complete self and informant versions of a Big Five Inventory. Participants were also photographed, while they were requested to maintain an emotionally neutral expression. A subset of the initial sample completed a shortened version of the Big Five Inventory in response to the pictures of other opposite sex participants (with whom they were unacquainted). Oosterhof and Todorov’s (in Proc Natl Acad Sci USA 105:11087–11092, 2008) computer-based model of face evaluation was used to generate facial trait scores on trustworthiness, dominance, and attractiveness, based on participants’ photographs. Results revealed that structural facial characteristics, suggestive of greater trustworthiness, predicted positively biased, global informant evaluations of a target’s personality, among both spouses and strangers. Among spouses, this effect was impervious to marriage length. There was also evidence suggestive of a Dorian Gray effect on personality, since facial trustworthiness predicted not only spousal and stranger, but also self-ratings of extraversion. Unexpectedly, though, follow-up analyses revealed that (low) facial dominance, rather than (high) trustworthiness, was the strongest predictor of self-rated extraversion. Our present findings suggest that subtle emotional cues, embedded in the structure of emotionally neutral faces, exert long-lasting effects on personality judgments even among very well-acquainted targets and perceivers.     

Influences of Infant‐Directed Speech on Early Word Recognition

When addressing infants, many adults adopt a particular type of speech, known as infant‐directed speech (IDS). IDS is characterized by exaggerated intonation, as well as reduced speech rate, shorter utterance duration, and grammatical simplification. It is commonly asserted that IDS serves in part to facilitate language learning. Although intuitively appealing, direct empirical tests of this claim are surprisingly scarce. Additionally, studies that have examined associations between IDS and language learning have measured learning within a single laboratory session rather than the type of long‐term storage of information necessary for word learning. In this study, 7‐ and 8‐month‐old infants' long‐term memory for words was assessed when words were spoken in IDS and adult‐directed speech (ADS). Word recognition over the long term was successful for words introduced in IDS, but not for those introduced in ADS, regardless of the register in which recognition stimuli were produced. Findings are discussed in the context of the influence of particular input styles on emergent word knowledge in prelexical infants.     

When Physical and Vocal Attractiveness Differ: Effects on Favorability of Interpersonal Impressions

Previous research has shown that targets whose physical and vocal attractiveness do not match (one channel being high and the other being low in attractiveness) elicit more negative impressions. The present study replicated this result and showed that the mediator and, hence, the reason for this effect is not simply a perception that the face and voice are discrepant but rather some disappointment with the less attractive channel. The finding that perceivers are overly disappointed with the less attractive channel is consistent with a large literature indicating that effects of negative events such as unattractive face or voice are stronger than effects of positive events.     

A study on the influence of headphones in auditory perceptual function

The focus of this study is a human's ability to make full use of listening and hearing. This ability consists of dividing auditory information into a signal and a noise. To evaluate the risk of using headphones, the study investigated the auditory perception when a warning sound is given in the presence of environmental noise.     

Parent and Nonparent Perception of the Multimodal Infant Cry

This study examined whether perceivers can detect infant distress in the visual and acoustic signals within the cry. Parent and nonparent perceivers rated distress in 3‐, 6‐, 8‐, and 12‐month‐old infants' cries that were manipulated to separate facial, vocal, and bodily action. Mean perceiver ratings differed for high‐ and low‐distress cries at each infant age on the basis of facial and vocal action, but not bodily movement. Perceivers rated the cry sound as more distressed and the cry face as less distressed with increasing infant age. Parents rated the cries as less distressed overall than did nonparents. The results suggest that information about distress is available for perceivers in the crying infant's face and voice.     

Effects of Seeing and Hearing Vowels on Neonatal Facial Imitation

For several decades, many authors have claimed the existence, early in life, of a tight link between perceptual and productive systems in speech. However, the question whether this link is acquired or is already present at birth remains open. This study aimed at investigating this question by employing the paradigm of neonatal facial imitation. We compared imitative responses of newborn infants presented either visual‐only, audiovisual congruent, or audiovisual incongruent models. Our results revealed that the newborns imitated significantly more quickly the movements of the model's mouth when this model was audiovisual congruent rather than visual‐only. Moreover, when observing an audiovisual incongruent model, the newborns did not produce imitative behavior. These findings, by highlighting the influence of speech perception on newborns' imitative responses, suggest that the neural architecture for perception–production is already in place at birth. The implications of these results are discussed in terms of a link between language and neonatal imitation, which could represent a precursor of more mature forms of vocal imitation and speech development in general.     

Effects of preinteraction expectancies on interaction involvement and behavioral responses in initial interaction

The link between preinteraction expectancies and the structure of interaction was examined in initial interaction. Unacquainted dyads were taped having a five minute interaction in which they talked about anything they desired. A 3 × 2 × 5 between-within subjects design was used to determine the impact of preinteraction expectancies on conversational behaviors reflecting friendliness and affiliation. The first between-factor consisted of three levels of expectancy: friendly, unfriendly, and no-expectancy. The second between-factor was sex composition of the dyads (male, female). The within-factor was time interval which acted as a repeated measure across a series of five, one-minute interaction periods. Subjects were designated as perceivers (those who were in one of the expectancy conditions) or targets (no preinteraction expectancy was induced). Results revealed that unfriendly-expectancy perceivers initiated talk more than friendly and no-expectancy perceivers, as well as talking more during the first minute of interaction, compared to no-expectancy perceivers. In addition, unfriendly-expectancy perceivers rated greater effort in compensating for the target's lack of friendliness than did subjects in the other conditions. The results are discussed in terms of an interaction goals perspective of initial interaction in which there is a preference for smooth, friendly interaction.The author would like to thank Dean Hewes, Richard Street Jr., and William Ickes for their comments on an earlier draft of this paper.     

The impact of attitude strength on customer-oriented priority setting by decision-makers: An empirical investigation

A key question in marketing decision-making pertains to what makes decision-makers focus on various types of information in different ways. Particularly in relation to a key marketing and management variable such as customer satisfaction this is an important issue. Costly derived customer satisfaction measures need to provide customer-oriented guidance regarding where to prioritise. Traditional research on intelligence use has mainly focused on objective research attributes, such as research quality. In this article, however, we will adopt the idea that decision-makers weigh information differently based on their perception of its relevance. With respect to crucial customer satisfaction information this represents an exciting, but nevertheless unexplored field of research. The results of latent variable modelling show that the strength of decision-makers’ attitudes toward customer satisfaction leads to a differentiated usage of satisfaction intelligence. By taking this into consideration, management and intelligence providers will be able to more effectively disseminate customer satisfaction information and facilitate a more customer-oriented perspective within firms.     

Developmental Change in Infants' Detection of Visual Faces that Match Auditory Vowels

Infants demonstrate robust audiovisual (AV) perception, detecting, for example, which visual face matches auditory speech in many paradigms. For simple phonetic segments, like vowels, previous work has assumed developmental stability in AV matching. This study shows dramatic differences in matching performance for different vowels across the first year of life: 3‐, 6‐, and 9‐month‐olds were familiarized for 40 sec with a visual face articulating a vowel in synchrony with auditory presentations of that vowel, but crucially, the mouth of the face was occluded. At test, infants were shown two still photos of the same face without occlusion for 1 min in silence. One face had a static articulatory configuration matching the previously heard vowel, while the other face had a static configuration matching a different vowel. Three auditory vowels were used: /a/, /i/, and /u/. Results suggest that AV matching performance varies according to age and to the familiarized vowel. Interestingly, results are not linked to the frequency of vowels in auditory input, but may instead be related to infants' ability to produce the target vowel. A speculative hypothesis is that vowel production in infancy modulates AV vowel matching.     

Where Infants Look Determines How They See: Eye Movements and Object Perception Performance in 3‐Month‐Olds

A fundamental question of perceptual development concerns how infants come to perceive partly hidden objects as unified across a spatial gap imposed by an occluder. Much is known about the time course of development of perceptual completion during the first several months after birth, as well as some of the visual information that supports unity perception in infants. The goal of this investigation was to examine the inputs to this process. We recorded eye movements in 3‐month‐old infants as they participated in a standard object unity task and found systematic differences in scanning patterns between those infants whose post‐habituation preferences were indicative of unity perception versus those infants who did not perceive unity. Perceivers, relative to nonperceivers, scanned more reliably in the vicinity of the visible rod parts and scanned more frequently across the range of rod motion. These results suggest that emerging object concepts are tied closely to available visual information in the environment, and the process of information pickup.     

Factors that influence organisational crisis perception from an internal stakeholder’s point of view

This paper starts from the premise that crisis is a perception and that one of the best ways to conquer a crisis is not to allow it to develop in the first place. By detecting or perceiving a crisis before other stakeholders do, an organisation can prevent or mitigate a crisis. Few studies have considered the question of whether organisations put the right people in the right places to be able to see a crisis coming. Within an organisation, managers are usually well placed to take decisions to initiate crisis communication, but they seem to be reluctant to do so or may not wish to see an impending crisis. Communication professionals should have a better perception of a crisis, but they rarely find themselves in a position to have a substantial impact on the management decision to communicate during a crisis. In this paper, we study crisis perception by individuals in a large governmental organisation during various stages of an unfolding crisis and compared perception scores to individual profiles based on study background, professional situation and crisis experience. This study involves a large-scale scenario-driven survey with ‘crisis perception’ as the main dependent variable. The results of this specific case indicate that an academic communication degree, a high hierarchical position in the organisation and crisis experience are positively related to an augmented perception of an impending organisational crisis.     

The rejected voice: towards intersubjectivity in speech language pathology

Speech language pathology needs to be linked with philosophy. Those with communication impairments encounter many problems when engaging in conversation with others. Does only the speaker(s) bear the responsibility to make their speech intelligible? In order to answer this question, I suggest that a Wittgensteinian approach offers original insights into speech as an intersubjective phenomenon. By exploring my experiences of having speech difficulties due to cerebral palsy, I shall argue that the unintelligibility of my voice is not simply my failure to achieve the able-spoken standard(s) of speech, but also the failure of others to recognise my utterance as speech. I hope to offer a different account of the voice that defines the human voice as intelligible speech – one that provides a more appropriate philosophical diversity for understanding the ethics of articulation.     

Does Self-Identifying as Having a Health Problem Precede Medical Contact? The Case of Infertility

ABSTRACT

Studies of medical help-seeking presume that self-identifying as having a health problem precedes medical contact, but this ordering of the identity-behavior relationship has not been systematically examined. We used longitudinal data from the National Survey of Fertility Barriers (2004 to 2010) on 412 women with infertility to document the temporal relationship between self-identifying as having a fertility problem and making medical contact. The symbolic interactionist perspective suggests that infertility will be perceived as identity disruption and that in response women will align self-identity and medical behavior over time. Cross-tabulation analysis indicated that more women do self-identify as having a fertility problem first (24%) as opposed to making medical contact first (5.5 percent). There was also a tendency toward aligning self-identification and behavior over time. Latent class analyses revealed six patterns: 1) consistently involved, 2) early consulters, 3) consistently uninvolved, 4) consistent perceivers, 5) medical dropouts, and 6) early perceivers. Strong fertility intent and primary infertility, two identity-relevant characteristics, had the strongest associations with latent class membership. The relationship between self-identification and medical help-seeking is thus dynamic and complex.     

Clause Segmentation by 6‐Month‐Old Infants: A Crosslinguistic Perspective

Each clause and phrase boundary necessarily aligns with a word boundary. Thus, infants' attention to the edges of clauses and phrases may help them learn some of the language‐specific cues defining word boundaries. Attention to prosodically well‐formed clauses and phrases may also help infants begin to extract information important for learning the grammatical structure of their language. Despite the potentially important role that the perception of large prosodic units may play in early language acquisition, there has been little work investigating the extraction of these units from fluent speech by infants learning languages other than English. We report 2 experiments investigating Dutch learners' clause segmentation abilities. In these studies, Dutch‐learning 6‐month‐olds readily extract clauses from speech. However, Dutch learners differ from English learners in that they seem to be more reliant on pauses to detect clause boundaries. Two closely related explanations for this finding are considered, both of which stem from the acoustic differences in clause boundary realizations in Dutch versus English.     

Online amplification of air pollution risk perception: the moderating role of affect in information

This study investigates the amplification effect of the Internet on Chinese people’s air pollution risk perception. Analyses are based on data collected from a sample of Internet users in Beijing, Shanghai, and Guangzhou (N?=?328). This study assumes that the characteristics of online information ? availability of information and affect in information ? will significantly contribute to the increase in air pollution risk perception. Results of path analysis indicated marginal significance of the effect of information availability on air pollution risk perception. Regarding the influence of affect in information, results showed that information including appeals to affect significantly increased perceived risk of air pollution; meanwhile, it also functioned as a moderator that significantly increased the strength of the causal relationship between information availability and risk perception. Findings of this study suggest that strategies for appropriately amplifying risk perception such as using heuristics may contribute to promoting public awareness of risks as well as encouraging public participation in the social effort to tackle risks.     

Infants’ Discrimination of Familiar and Unfamiliar Accents in Speech

This study investigates infants’ discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head‐turn preference procedure, 5‐month‐old infants demonstrated that they were able to distinguish between their own South‐West English accent and an unfamiliar Welsh English accent. However, this distinction was not seen when two unfamiliar accents (Welsh English and Scottish English) were presented to the infants, indicating they had not acquired the general ability to distinguish between regional varieties, but only the distinction between their home accent and unfamiliar regional variations. This ability was also confirmed with 7‐month‐olds, challenging recent claims that infants lose their sensitivity to dialects at around that age. Taken together, our results argue in favor of an early sensitivity to the intonation system of languages, and to the early learning of accent‐specific intonation and potentially segmental patterns. Implications for the development of accent normalization abilities are discussed.     

Helping Dutch Neighborhood Watch Schemes to Survive the Rainy Season: Studying Mutual Perceptions on Citizens’ and Professionals’ Engagement in the Co-Production of Community Safety

Despite the growing research interest in co-production, some important gaps in our knowledge remain. Current literature is mainly concerned with either the citizens or professionals being involved in co-production, leaving unanswered the question how co-producers and professionals perceive each other’s engagement, and how this is reflected in their collaboration. This study aims to answer that question, conducting an exploratory case study on neighborhood watch schemes in a Dutch municipality. Empirical data are collected through group/individual interviews, participant observations, and document analysis. The results show that the perceptions citizens and professionals hold on their co-production partner’s engagement indeed impact on the collaboration. Moreover, for actual collaboration to occur, citizens and professionals not only need to be engaged but also to make this engagement visible to their co-production partner. The article concludes with a discussion of the practical implications of these findings.     

The effects of target attractiveness on men's sexual arousal in response to erotic auditory stimuli

Previous research on sexual arousal resulting from auditory stimuli indicates that visual imagery acts as a mediator between stimulus input and resulting arousal. This leads to the question of whether imagery, and subsequent arousal, can be manipulated by providing differing information to hold in semantic memory. This research hypothesizes that attractive images held within semantic memory and pattern-matched with an erotic auditory stimulus facilitate higher self-reported arousal, and at a more rapid rate, than unattractive images. Participants in an "Unattractive" condition experienced slower rates and lower mean levels of arousal in response to an auditory stimulus, compared to participants in an "Attractive" or "No Picture" condition. No differences existed between groups in maximum arousal scores or the tendency to visualize the target during the listening task. Implications for the role of imagery in sexual response, possible measurement issues, and suggestions for future research are addressed in the discussion.
