  • 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 semantic matching images relative to color matching images, for example, orient faster to an image of a cookie relative to a yellow cup upon hearing the word 'banana'? The results strongly suggest a prioritization of semantic information over color information in children's word-referent mappings. This indicates that even for natural objects (e.g., food, animals that are more likely to have a prototypical color), semantic knowledge is a more salient aspect of toddler's word meaning than color knowledge. For 24-month-old Dutch toddlers, bananas are thus more edible than they are yellow.

  • Fourteen-month-olds pay attention to vowels in novel words

    Recent research has shown that infants are sensitive to mispronunciations of words when tested using a preferential looking task. The results of these studies indicate that infants are able to access the phonological detail of words when engaged in lexical recognition. However, most of this work has focused on mispronunciations of consonants in familiar and novel words. Very little is known about the role that vowels play in constraining lexical access during the early stages of lexical development. We describe a word learning study with 14- and 18-month-old infants that tests their sensitivity to mispronunciations of word-medial vowels using a preferential looking task. We found that both age groups demonstrated recognition of correctly pronounced tokens of the newly learnt words but not mispronounced tokens. These results indicate that vowels constrain lexical access of novel words by as early as 14 months of age, and add to the growing body of literature indicating that infants exploit detailed phonological information when processing both familiar and newly learnt words.

  • Effects of learning context on the acquisition and processing of emotional words in bilinguals

    Although bilinguals respond differently to emotionally valenced words in their first language (L1) relative to emotionally neutral words, similar effects of emotional valence are hard to come by in second language (L2) processing. We examine the extent to which these differences in first and second language processing are due to the context in which the 2 languages are acquired: L1 is typically acquired in more naturalistic settings (e.g., family) than L2 (e.g., at school). Fifty German–English bilinguals learned unfamiliar German and English negative and neutral words in 2 different learning conditions: One group (emotion video context) watched videos of a person providing definitions of the words with facial and gestural cues, whereas another group (neutral video context) received the same definitions without gestural and emotional cues. Subsequently, participants carried out an emotional Stroop task, a sentence completion task, and a recall task on the words they had just learned. We found that the effect of learning context on the influence of emotional valence on responding was modulated by a) language status, L1 versus L2, and b) task requirement. We suggest that a more nuanced approach is required to capture the differences in emotion effects in the speed versus accuracy of access to words across different learning contexts and different languages, in particular with regard to our finding that bilinguals respond to L2 words in a similar manner as L1 words provided that the learning context is naturalistic and incorporates emotional and prosodic cues.

  • Early word segmentation in naturalistic environments: Limited effects of speech register

    We examined 7.5‐month‐old infants' ability to segment words from infant‐ and adult‐directed speech (IDS and ADS). In particular, we extended the standard design of most segmentation studies by including a phase where infants were repeatedly exposed to target word recordings at their own home (extended exposure) in addition to a laboratory‐based familiarization. This enabled us to examine infants' segmentation of words from speech input in their naturalistic environment, extending current findings to learning outside the laboratory. Results of a modified preferential‐listening task show that infants listened longer to isolated tokens of familiarized words from home relative to novel control words regardless of register. However, infants showed no recognition of words exposed to during purely laboratory‐based familiarization. This indicates that infants succeed in retaining words in long‐term memory following extended exposure and recognizing them later on with considerable flexibility. In addition, infants segmented words from both IDS and ADS, suggesting limited effects of speech register on learning from extended exposure in naturalistic environments. Moreover, there was a significant correlation between segmentation success and infants' attention to ADS, but not to IDS, during the extended exposure phase. This finding speaks to current language acquisition models assuming that infants' individual attention to language stimuli drives successful learning.

  • Early word recognition in sentence context: French and English 24-month-olds' sensitivity to sentence-medial mispronunciations and assimilations

    Investigated 24-month-olds' word recognition in sentence-medial positions in two experiments using an intermodal preferential-looking paradigm. In Experiment 1, 33 French toddlers detected word-final voicing mispronunciations and compensated for native voicing assimilations in the middle of sentences. In Experiment 2, 31 English toddlers detected word-final voicing mispronunciations but did not compensate for illicit voicing assimilations. In summary, French and English 24-month-olds can take into account fine phonetic detail even if words are presented in the middle of sentences. In addition, French toddlers show language-specific compensation abilities for pronunciation variation caused by native voicing assimilation.

  • Early word learning

    Early Word Learning explores the overlapping and interactive processes leading to young children learning words and their meanings. Experts in the field review the development of early lexical acquisition, starting with an infant's learning of native speech sounds, to segmenting proto-words from fluent speech, mapping individual words to meanings in the face of natural variability and uncertainty, and developing a structured mental lexicon. Drawing on cutting-edge research in infant eye-tracking, neuroimaging techniques and computational modelling, this book surveys the field covering both established results and the most recent advances in word learning research. The chapters combine empirical, computational and theoretical perspectives, to provide a comprehensive yet coherent and unified representation of early word learning, spanning the first two years of life. It is essential reading for both undergraduate and postgraduate courses in early language development and developmental psycholinguistics as well as researchers in these fields.

  • Does size matter? Subsegmental cues to vowel mispronunciation detection

    Children look longer at a familiar object when presented with either correct pronunciations or small mispronunciations of consonants in the object's label, but not following larger mispronunciations. The current article examines whether children display a similar graded sensitivity to different degrees of mispronunciations of the vowels in familiar words, by testing children's sensitivity to 1-feature, 2-feature and 3-feature mispronunciations of the vowels of familiar labels: Children aged 1;6 did not show a graded sensitivity to vowel mispronunciations, even when the trial length was increased to allow them more time to form a response. Two-year-olds displayed a robust sensitivity to increases in vowel mispronunciation size, differentiating between small and large mispronunciations. While this suggests that early lexical representations contain information about the features contributing to vocalic identity, we present evidence that this graded sensitivity is better explained by the acoustic characteristics of the different mispronunciation types presented to children.

  • Categorizing with gender: Does implicit grammatical gender affect semantic processing in 24-month-old toddlers?

    The current study investigated the interaction of implicit grammatical gender and semantic category knowledge during object identification. German-learning toddlers (24-month-olds) were presented with picture pairs and heard a noun (without a preceding article) labeling one of the pictures. Labels for target and distracter images either matched or mismatched in grammatical gender and either matched or mismatched in semantic category. When target and distracter overlapped in both semantic and gender information, target recognition was impaired compared with when target and distracter overlapped on only one dimension. Results suggest that by 24 months of age, German-learning toddlers are already forming not only semantic but also grammatical gender categories and that these sources of information are activated, and interact, during object identification.

  • Building a lexical network

    The adult lexicon is organized among many representational dimensions that encode phonological, semantic and perceptual links among words. Priming studies that use behavioral, eye-tracking and electrophysiological measurements highlight the interactive and dynamic nature of lexical processing and representation in the adult lexicon. These studies suggest that word recognition routinely involves simultaneous access to other words that overlap with a spoken word on phonological, semantic or other perceptual dimensions. While these studies provide valuable information about the mechanisms guiding lexical retrieval and the factors underlying lexical organization in the lexicons of adult college-educated individuals who know many thousands of words, it is debatable the extent to which these findings can be extended to our understanding of early lexical processing in young children. On the one hand, differences in general cognitive abilities, linguistic experience and language-related knowledge in young children and college-educated adults could imply drastic differences in the way words are linked in developing and mature lexicons. On the other hand, once a word has an entry in the mental lexicon, how many or which other words the child knows may be irrelevant, such that a) the structure of the developing lexicon is a miniature version of the adult lexicon, organized according to similar dimensions; and b) the processes guiding word recognition differ minimally across development. Adjudicating between these two proposals requires examination of the structure of the early lexicon and the processes guiding lexical processing in young children. How does this structure initially develop and change as the child’s knowledge grows over time? Does the organization of the early lexicon influence subsequent word learning and word processing? Understanding these questions has the potential to inform adult theories of psycholinguistic processing and highlight important processes in early vocabulary development. This chapter will attempt to answer these questions against the background of the literature to date whilst also sketching paths for future research on the topic.

  • Bilinguals implicitly name objects in both their languages: An ERP study

    Examined whether bilinguals implicitly generate picture labels in both of their languages when tested in their first language (L1) with a cross-modal event-related potential (ERP) priming paradigm. The results extended previous findings by showing that not only do bilinguals implicitly generate the labels for visually fixated images in both of their languages when immersed in their L1, but also that these implicitly generated labels in one language could prime recognition of subsequently presented auditory targets across languages (i.e., L2-L1). Thus, support is provided for cascaded models of lexical access during speech production as well as a new priming paradigm for the study of bilingual language processing.

  • Audiovisual speech perception in infancy: The influence of vowel identity and infants’ productive abilities on sensitivity to (mis)matches between auditory and visual speech cues

    Recent studies suggest that infants’ audiovisual speech perception is influenced by articulatory experience (Mugitani et al., 2008; Yeung & Werker, 2013). The current study extends these findings by testing if infants’ emerging ability to produce native sounds in babbling impacts their audiovisual speech perception. We tested 44 6-month-olds on their ability to detect mismatches between concurrently presented auditory and visual vowels and related their performance to their productive abilities and later vocabulary size. Results show that infants’ ability to detect mismatches between auditory and visually presented vowels differs depending on the vowels involved. Furthermore, infants’ sensitivity to mismatches is modulated by their current articulatory knowledge and correlates with their vocabulary size at 12 months of age. This suggests that—aside from infants’ ability to match nonnative audiovisual cues (Pons et al., 2009)—their ability to match native auditory and visual cues continues to develop during the first year of life. Our findings point to a potential role of salient vowel cues and productive abilities in the development of audiovisual speech perception, and further indicate a relation between infants’ early sensitivity to audiovisual speech cues and their later language development.

  • Activation of phonological and semantic codes in toddlers

    What are the processes underlying word recognition in the toddler lexicon? Work with adults suggests that, by 5-years of age, hearing a word leads to cascaded activation of other phonologically, semantically and phono-semantically related words (Huang & Snedeker, 2010; Marslen-Wilson & Zwitserlood, 1989). Given substantial differences in children’s sensitivity to phonological and semantic relationships between words in the first few years of life (Arias-Trejo & Plunkett, 2010; Newman, Samuelson, & Gupta, 2009; Storkel & Hoover, 2012), the current set of experiments investigated whether children younger than five also show such phono-semantic priming. Using a picture-priming task, Experiments 1 and 2 presented 2-year-olds with phono-semantically related prime-target pairs, where the label for the prime image is phonologically related (Experiment 1 – onset CV overlap, Experiment 2 – rhyme VC overlap) to a semantic associate of the target label. Across both experiments, toddlers recognised a word faster when this was preceded by a phono-semantically related prime relative to an unrelated prime. Overall, the results provide strong evidence that word recognition involves cascaded processing of phono-semantically related words by 2-years of age.

  • “Proactive” in many ways: Developmental evidence for a dynamic pluralistic approach to prediction.

    The anticipation of the forthcoming behaviour of social interaction partners is a useful ability supporting interaction and communication between social partners. Associations and prediction based on the production system (in line with views that listeners use the production system covertly to anticipate what the other person might be likely to say) are two potential factors, which have been proposed to be involved in anticipatory language processing. We examined the influence of both factors on the degree to which listeners predict upcoming linguistic input. Are listeners more likely to predictbookas an appropriate continuation of the sentence “The boy reads a”, based on the strength of the association between the wordsreadandbook(strong association) andreadandletter(weak association)? Do more proficient producers predict more? What is the interplay of these two influences on prediction? The results suggest that associations influence language-mediated anticipatory eye gaze in two-year-olds and adults only when two thematically appropriate target objects compete for overt attention but not when these objects are presented separately. Furthermore, children's prediction abilities are strongly related to their language production skills when appropriate target objects are presented separately but not when presented together. Both influences on prediction in language processing thus appear to be context dependent. We conclude that multiple factors simultaneously influence listeners’ anticipation of upcoming linguistic input and that only such a dynamic approach to prediction can capture listeners’ prowess at predictive language processing.

  • When mistakes affecting one's own group result in compensation: Evidence of a compensatory own goal effect

    Objectives Although sports team members often value their teams highly, they sometimes make mistakes and thereby unintentionally put their teams at a disadvantage. Thus, they should be motivated to compensate for their mistake to resolve this discrepancy. To test this hypothesis, we studied whether professional soccer players compensate for their own goals by scoring regular goals in the same game (Study 1) and possible processes underlying such compensation efforts (Study 2). Design In Study 1, we compared how frequently prior own goal scorers scored a regular goal in the same game to (a) their expected goal scoring frequencies and (b) their probabilities to score a regular goal following a regular goal by the opposing team. In Study 2, we investigated four possible processes underlying the expected compensatory efforts. Method We analyzed all own goals from the first fifty years of the German Bundesliga (N = 889) and possible ensuing regular goals by the own goal scorer. Moreover, we surveyed amateur soccer players about four motives: group performance, individual performance, individual public image, and group public image. Results Following their own goals, professional soccer players are particularly likely to score regular goals in the same game (i.e., a compensatory own goal effect). Presumably, they primarily do so to secure a good group performance, but the other motives also play a role. Conclusions Group members who make highly visible mistakes are motivated to compensate for the disadvantage they caused. Presumably, they mainly do so to secure a good team Performance.

  • Biased information search in group decision making.

    Research has shown that people prefer supporting to conflicting information when making decisions. Whether this biased information search also occurs in group decision making was examined in three experiments. Experiment 1 indicated that groups as well as individuals prefer supporting information and that the strength of this bias depends on the distribution of the group members' initial decision preferences. The more group members had chosen the same alternative prior to the group discussion (group homogeneity), the more strongly the group preferred information supporting that alternative. Experiment 2 replicated these results with managers. Experiment 3 showed that the differences between homogeneous and heterogeneous groups reflect group-level processes. Higher commitment and confidence in homogeneous groups mediated this effect. Functional and dysfunctional aspects of biased information seeking in group decision making are discussed.

  • Tax decisions are more conflicting under legitimate than coercive tax authority- an ERP study
  • The impact of powerful authorities and trustful taxpayers: Evidence for the extended slippery slope framework from Austria, Finland and Hungary

    Tax authorities utilize a wide range of instruments to motivate honest taxpaying ranging from strict audits to fair procedures or personalized support, differing from country to country. However, little is known about how these different instruments and taxpayers’ trust influence the generation of interaction climates between tax authorities and taxpayers, motivations to comply, and particularly, tax compliance. The present research examines the extended slippery slope framework (eSSF), which distinguishes tax authorities’ instruments into different qualities of power of authority (coercive and legitimate) and trust in authorities (reason-based and implicit), to shed light on the effect of differences between power and trust. We test eSSF assumptions with survey data from taxpayers from three culturally different countries ( N  = 700) who also vary concerning their perceptions of power, trust, interaction climates, and tax motivations. Results support assumptions of the eSSF. Across all countries, the relation of coercive power and tax compliance was mediated by implicit trust. The connection from legitimate power to tax compliance is partially mediated by reason-based trust. The relationship between implicit trust and tax compliance is mediated by a confidence climate and committed cooperation. Theoretical and practical implications are discussed.
