Previous studies have found that bilingual children receive different Give-Number task knower-levels across their languages as subset-knowers. However, recent work reveals that the reliability of Give-Number task is moderate for subset-knower levels. This raises the possibility that the differences found in knower-levels across bilinguals’ languages are explained by a lack of reliability of Give-Number. To address this possibility, we presented bilingual children with Give-Number and a subitizing task that they had to perform in both languages. If differences in knower-levels are due to true differences in children’s understanding of small numbers and not random noise, then differences in subitizing abilities should also be non-random. Data collection is still in progress, but preliminary planned analyses (N=13/64) revealed no differences in subitizing abilities across languages, based on knower-levels classification. We discuss implications of these findings on knowledge transfer across bilinguals’ languages.

Evidence shows comparing events helps children learn verbs (e.g., Childers et al., 2016), but studies are needed to understand whether event type is important. Study 1 examines two types of experiences during learning: seeing similar events than varied, or all varied events. Two½-(n=22), 3½-(n=20) and 4½-year-olds(n=14) learned 4 novel verbs. BS:similar events first or all varied events; pointed at test. A 3(Age: 2,3,4 years) x 2(Condition: similar,varied) univariate ANOVA,dv=proportion correct, showed main effect of Age, F(2, 55)= 7.6, p=.001 only. All children succeeded (one sample t-tests,ps< .03), whereas in a prior study, younger children failed. A second study confirms these results with a different set of video events, and events separated by 1-minute distractors. Here, only 2½- and 3½-year-olds who saw similar events extended verbs,perhaps because events were separated in time. These studies show that verb learners can benefit from comparing events, and comparing similar events can be especially useful.

As time series analysis continues to capture the interest of cognitive and behavioral researchers, it is increasingly important to evaluate these methods and compare their respective insights. Here, we evaluate three popular analyses: vector autoregression, cross-correlation, and cross-recurrence quantification analysis. Using social cohesion data derived from Twitter and daily counts of real-world events during the Arab Spring, we present a case study using these methods and evaluate their benefits, limitations, and differences in results. We propose that researchers interested in time series analysis consider these differences and use multiple methods to assure reliability of their results.

Vector Autoregression, Cross-Correlation, and Cross-Recurrence Quantification Analysis: A Case Study in Social Cohesion and Collective Action

The purpose of this study is to capture the structure of the interactive role-making process and introduce an integrated perspective to view actors’ creativity in the process. In particular, this study focuses on the characteristics of utterances in an acting training, which emphasizes paying attention to a partner and communicating. Statistical analyses are conducted on temporal changes, individual differences, and the granularity of utterances. The influence of attention toward partners on utterances is discussed, as well as the possible internal changes of actors, which reflects a perspective from which to view creative action as is referred to in the five A’s framework. In addition, by applying the theory of constructed emotion, the present study attempts to provide a possible demonstration of how truthful emotion is born under imaginary settings in acting.

Zipf’s Law of Abbreviation (ZLA) states that the more frequently a word is used, the shorter its length tends to be. This arises due to the optimal trade-off between competing pressures for accuracy and efficiency in communication, known as the Principle of Least Effort. Existing research has not focused on how individuals adapt their language use to remain optimal despite language change and whether social factors like common ground affect this. To investigate this, we replicated and extended the artificial language learning paradigm and communication game of Kanwal et al. (2017). We found participants were able to re-optimize their language use according to ZLA after a language change event, but this ability was hampered by common ground. This research identifies common ground as one potential cause for observed sub-optimalities in human languages and may have implications for understanding the dynamics of language change across communities where common ground varies.

Infants have been shown to be particularly adept at extracting so-called non-adjacent dependencies (NADs) from auditory linguistic input (for a review, cf. Mueller, Milne, & Männel, 2018). Mueller, Friederici & Männel (2012) showed that 3-4 month-olds readily learn arbitrary associations between specific non-adjacent syllables from an artificial language (e.g. fikato) and related this ability to individual differences in pitch processing. Here, we addressed the question whether syllables are the building block NAD learning operates on, or whether smaller segmental units also allow for such structural generalizations (Nespor, Peña, & Mehler, 2003). In an oddball paradigm, 8-10-months-olds showed a differential ERP response to standard (e.g. bokäwu, liwase) and deviant (e.g. sogäle, kisüru) exemplars of an exclusively vowel-based NAD, and to an intensity manipulation. Implications of successful rule generalization from this smaller segmental unit and its relation to auditory sensory processing are discussed.

Children typically do not spontaneously recognize accented productions of known words until approximately 19 months. In 15-month-olds, however, this ability is correlated with vocabulary size. Vocabulary size may support cross-accent accommodation by decreasing the likelihood that a variant production is considered to be an unknown word. We simulated a cross-accent word identification experiment, with word tokens generated from a two-dimensional Gaussian space, and accented productions simulated via linear transforms. Simulated participants were Bayesian classifiers with large or small vocabularies. Our large vocabulary group accurately classified more accented tokens and were less likely to classify an accented token as an unknown word. Thus, one way a growing vocabulary size may foster cross-accent accommodation is through increasing infants’ propensity to fit accented variants to known words, rather than treating them as unknown words.

A considerable amount of cognition is, in some way, social. Here we consider one example: our reliance upon experts for information about phenomenon within a particular domain. Novices and experts share some knowledge within a domain in question which is crucial for knowing when to seek expert advice and how to evaluate that advice. Just when we decide to relinquish our own knowledge or skill in deference to an expertise remains an important question for cognitive scientists. Here we explored some conditions that might influence when we choose to defer to experts. In two experiments (N=570) we demonstrated that participants have a greater willingness to defer when experts have provide descriptive information (i.e., facts) about their domain of expertise, than when they provide prescriptive advice about what we ought to do with those facts. We interpret these results from the perspective that individuals exercise greater vigilance when given prescriptive advice in the form of normative statements. From this perspective individuals feel threatened, and therefore are less deferential, when experts tell them what to do, rather than share knowledge with them.

What we ought to do is…’: Are we More Willing to Defer to Experts who Provide Descriptive Facts Than Those who Offer Prescriptive Advice?

Language acquisition is supported by an ability called phonological awareness, which allows children to become intentionally aware of phonological units. It is known that erroneous pronunciation appears during the formation of phonological awareness. To clarify children's internal processes during this formation, this research aims to examine the factors that correct an erroneous phonological generation process. To do this, we utilized the innate and experiential factors of the memory retrieval mechanism in the cognitive architecture ACT-R. Specifically, we performed simulations to examine the interaction tasks that contribute to the acquisition of phonological awareness. As a result, it was shown that repeating a single task causes incorrect convergence and that this convergence can be prevented by performing other kinds of learning between tasks. In the future, it will be necessary to examine learning between tasks that can be associated with real situations and to confirm the overall process of phonological awareness formation.

How many rhymes are possible in English? How much alliteration or assonance? This paper explores the space of common phonologically driven poetic devices. I investigate instances of these poetic devices across unique words in the dictionary, assuming perfect matching in relevant corresponding elements of word pairs. Documenting the frequencies of poetic device matches across words provides a baseline for understanding the diversity and use of these forms in the wild. It also allows us to describe the distribution of words across these patterns within each poetic device. We show that certain devices, such as alliteration and stress, support a relatively small number of unique phonological patterns, providing more consolidated and predictable resources than other devices. Forms like masculine and feminine rhyme, assonance, and consonance display relatively more sound patterns respectively, and unique words are distributed across them differently. These results are discussed in terms of their poetic and cognitive implications.

Bilinguals are reported to have language learning advantages. One possible pathway is a language-specific transfer effect, whereby sensitivity to structural regularities in known languages can be brought to novel languages that share features. To test for specific linguistic feature transfer, we designed a task for bilinguals with homogeneous language exposure (bilingual in same languages) and heterogeneous feature representation (differing proficiencies). As Hindi and Mandarin have retroflexion in phoneme contrasts, we conducted a pre-registered study with a statistical learning task of a Hindi dental-retroflex contrast on parallel English-Mandarin bilinguals with varied Mandarin proficiency. Unlike the pilot study (N = 15), the main study (N = 50) found no evidence for a learning effect, and language-experience did not explain learning variance. As these stimuli have shown learning effects in children, learning effects for this feature may be fragile in this adult population, and language-specific neural commitments may prevent learning of the contrast.
