The Quest for Truth
Much of what children know about the world is learned from information provided by others, and children’s endorsement of this information depends on the social attributes of the person providing the information (e.g., their accent, attractiveness, etc.). Previous work on how the identity of a person providing information (i.e., informant) influences children’s learning has tended to focus on a highly specific, simplified learning context, where c…
It’s Hey Jude, not Hey Jade
A growing literature explores the representational detail of infants’ early lexical representations, but no study has investigated how exposure to real-life acoustic-phonetic variation impacts these representations. Indeed, previous experimental work with young infants has largely ignored the impact of accent exposure on lexical development. We ask how routine exposure to accent variation affects 6-month-olds’ ability to detect mispronunciations.…
Advancements in phonetics in the 21st century
Infant speech perception emerged as a field late in the 20th century. Early work focused on defining the initial state, and documenting the timecourse of changes in speech perception over the first year of life. At the turn of the century, attention shifted from studying when children became attuned to their native language, to asking how children achieved this transformation. Statistical learning became the dominant mechanism to explain language…
In Support of Varying Approaches to the Study of Variation
The acquisition of variation is a fundamental – but poorly understood – part of child language acquisition. We fully endorse Shin and Miller’s call for us to recognize the importance of this core issue, and argue that our understanding could be further enriched by greater reliance on convergent methods. As such, we implore researchers to consider perception as well as production data, and to consider acquisition across different domains and diffe…
Not gone away
Purpose The paper aims to understand how state and non-state domestic terrorism impacts MNEs in foreign markets. Despite the burgeoning literature on terrorism within international business (IB), most research has focused on international terrorism, or terrorism generally. Consequently, there has been limited research examining how domestic or local based terrorism impacts foreign firms. Design/methodology/approach This is a conceptual paper. Fin…
The Influence of Accent Distance on Perceptual Adaptation in Toddlers and Adults
Foreign accents can vary considerably in the degree to which they deviate from the listener’s native accent, but little is known about how the relationship between a speaker’s accent and a listener’s native language phonology mediates adaptation. Using an artificial accent methodology, we addressed this issue by constructing a set of three artificial accents (Near, Far, and Farther), varying in the number and magnitude of pronunciation deviations…
Cross-generational Phonetic Alignment between Mothers and Their Children
Over time, people who spend a lot of time together (e.g., roommates) begin sounding alike. Even over the course of short conversations, interlocutors often become more acoustically similar to one another. This phenomenon – known as phonetic alignment – has been well studied in adult interactions, but much less is known about alignment patterns in intergenerational, adult-child dyads. In the current study, we investigated alignment between mothers…

Comparing Phonetic Convergence in Children and Adults
Observations by sociolinguists suggest that when children relocate to a new community, they rapidly learn to imitate their peers, adopting the new local accent faster and more effectively than adults. However, few well-controlled laboratory experiments have been conducted comparing speech or accent imitation across ages. Here, we investigated Canadian English-speaking children’s and adults’ imitation of three model speakers: a Canadian English ta…
The Potential for a ‘Tiger King Effect’
During the COVID-19 pandemic in 2020, Netflix aired the docuseries Tiger King: Murder, Mayhem, and Madness. This aligned with the United States declaring a national emergency and the beginning of stay-at-home orders. Netflixexperienced a significant increase in viewership and a large number of responses to Tiger King’s content from viewers and media outlets (e.g., Stoll 2021). In this article, we present an analysis of social media responses on t…
Targeted adaptation in infants following live exposure to an accented talker
Infants struggle to understand familiar words spoken in unfamiliar accents. Here, we examine whether accent exposure facilitates accent-specific adaptation. Two types of pre-exposure were examined: video-based (i.e., listening to pre-recorded stories; Experiment 1) and live interaction (reading books with an experimenter; Experiments 2 and 3). After video-based exposure, Canadian English-learning 15- to 18-month-olds failed to recognize familiar …
Navigating Accent Variation
Adult processing of other-accented speech is fast, dependent on lexical access, and readily generalizable to new words. But what does children's processing of other-accented speech look like? Although many acquisition researchers have emphasized how other-accented speech presents a formidable challenge to young children, we argue that the field has perhaps underestimated children's early accent processing abilities. In support of this view, we pr…
Resolving the (Apparent) Talker Recognition Paradox in Developmental Speech Perception
The infant literature suggests that humans enter the world with impressive built‐in talker processing abilities. For example, newborns prefer the sound of their mother's voice over the sound of another woman's voice, and well before their first birthday, infants tune in to language‐specific speech cues for distinguishing between unfamiliar talkers. The early childhood literature, however, suggests that preschoolers are unable to learn to identify…
The effect of accent exposure on children’s sociolinguistic evaluation of peers
Language and accent strongly influence the formation of social groups. By five years of age, children already show strong social preferences for peers who speak their native language with a familiar accent (Kinzler, Shutts, DeJesus, & Spelke, 2009). However, little is known about the factors that modulate the strength and direction of children's accent-based group preferences. In three experiments, we examine the development of accent-based frien…
What infant-directed speech tells us about the development of compensation for assimilation
I Don't Like the Tone of Your Voice
Infants can make social judgments about characters by visually observing their interactions with others (e.g., Hamlin, Wynn & Bloom, Nature , 2007, 450 , 557). Here, we ask whether infants can form similar judgments about potential social partners based solely on their tone of voice. In Experiment 1, we presented 10.5‐month‐olds with two visually neutral puppets. One puppet spoke in a positive affect and the other spoke in a negative affect. When…
Toddlers’ Word Recognition in an Unfamiliar Regional Accent
Adults are generally adept at recognizing familiar words in unfamiliar accents. However, studies testing young children’s abilities to cope with accent-related variation in the speech signal have generated mixed results, with some work emphasizing toddlers’ early competence and other work focusing more on their long-lasting difficulties in this domain. Here, we set out to unify these two perspectives and propose that task demands may play a cruci…
Estimating the Development Assistance for Health Provided to Faith-Based Organizations, 1990–2013
BACKGROUND: Faith-based organizations (FBOs) have been active in the health sector for decades. Recently, the role of FBOs in global health has been of increased interest. However, little is known about the magnitude and trends in development assistance for health (DAH) channeled through these organizations. MATERIAL AND METHODS: Data were collected from the 21 most recent editions of the Report of Voluntary Agencies. These reports provide inform…
Constructing a Proto-Lexicon
Infants begin learning the phonological structure of their native language remarkably early and use this information to extract word-sized chunks from the speech signal. While acquiring the language-specific segmentation strategies appropriate for their native language, infants are simultaneously beginning to form word–object pairings and learning which sound contrasts are meaningful in the native language. They are also working out how to assign…
Global, regional, and national incidence and mortality for HIV, tuberculosis, and malaria during 1990–2013
The Developmental Trajectory of Toddlers’ Comprehension of Unfamiliar Regional Accents
Efficient language use involves the capacity to flexibly adjust to varied pronunciations of words. Although children can contend with some accent variability before their second birthday, it is currently unclear when and how this ability reaches its mature state. In a series of five experiments, we examine the developmental trajectory of toddlers’ comprehension of unfamiliar regional accents. Experiments 1 and 2 reveal that Canadian-English-learn…
How yellow is your banana? Toddlers' language-mediated visual search in referent-present tasks
What is the relative salience of different aspects of word meaning in the developing lexicon? The current study examines the time-course of retrieval of semantic and color knowledge associated with words during toddler word recognition: At what point do toddlers orient toward an image of a yellow cup upon hearing color-matching words such as "banana" (typically yellow) relative to unrelated words (e.g., "house")? Do children orient faster to sema…
Gender-marked determiners help Dutch learners' word recognition when gender information itself does not
Dutch, unlike English, contains two gender-marked forms of the definite article. Does the presence of multiple definite article forms lead Dutch learners to be delayed relative to English learners in the acquisition of their determiner system? Using the Preferential Looking Procedure, we found that Dutch-learning children aged 1 ; 7 to 2 ; 0 use articles during sentence comprehension in a fashion comparable to similarly aged English learners. Tha…
Question or tone 2? How language experience and linguistic function guide pitch processing
Developmental Changes in Infants’ Ability to Cope with Dialect Variation in Word Recognition
Toward the end of their first year of life, infants’ overly specified word representations are thought to give way to more abstract ones, which helps them to better cope with variation not relevant to word identity (e.g., voice and affect). This developmental change may help infants process the ambient language more efficiently, thus enabling rapid gains in vocabulary growth. One particular kind of variability that infants must accommodate is tha…

Statistical learning of tone sequences by human infants and adults
Previous research suggests that language learners can detect and use the statistical properties of syllable sequences to discover words in continuous speech (e.g. Aslin, R.N., Saffran, J.R., Newport, E.L., 1998. Computation of conditional probability statistics by 8-month-old infants. Psychological Science 9, 321-324; Saffran, J.R., Aslin, R.N., Newport, E.L., 1996. Statistical learning by 8-month-old infants. Science 274, 1926-1928; Saffran, J.,…

Word Segmentation by 8-Month-Olds
English‐Learning Infants' Representations of Word Forms With Iambic Stress
Retaining detailed representations of unstressed syllables is a logical prerequisite for infants' use of probabilistic phonotactics to segment iambic words from fluent speech. The head‐turn preference study was used to investigate the nature of English‐learners' representations of iambic word onsets. Fifty‐four 10.5‐month‐olds were familiarized to passages containing the nonsense iambic word forms ginome and tupong . Following familiarization, in…
Boundary alignment enables 11-month-olds to segment vowel initial words from speech
Past research has indicated that English-learning infants begin segmenting words from speech by 7·5 months of age (Jusczyk & Aslin, 1995). More recent work has demonstrated, however, that 7·5-month-olds' segmentation abilities are severely limited. For example, the ability to segment vowel-initial words from speech reportedly does not appear until 13·5 to 16 months of age (Mattys & Jusczyk, 2001; Nazzi, Dilley, Jusczyk, Shattuck-Hufnagel & Jusczy…
Clause Segmentation by 6‐Month‐Old Infants
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…
