''Piensa'' twice: On the foreign language effect in decision making

In this article, we assess to what extent decision making is affected by the language in which a given problem is presented (native vs. foreign). In particular, we aim to ask whether the impact of various heuristic biases in decision making is diminished when the problems are presented in a foreign language. To this end, we report four main studies in which more than 700 participants were tested on different types of individual decision making problems. In the first study, we replicated Keysar et al.s (2012) recent observation regarding the foreign language effect on framing effects related to loss aversion. In the second section, we assessed whether the foreign language effect is present in other types of framing problems that involve psychological accounting biases rather than gain/loss dichotomies. In the third section, we studied the foreign language effect in several key aspects of the theory of decision making under risk and uncertainty. In the fourth study, we assessed the presence of a foreign language effect in the cognitive reflection test, a test that includes logical problems that do not carry emotional connotations. The absence of such an effect in this test suggests that foreign language leads to a reduction of heuristic biases in decision making across a range of decision making situations and provide also some evidence about the boundaries of the phenomenon. We explore several potential factors that may underlie the foreign language effect in decision making.

More than words: the effect of multi-word frequency and constituency on phonetic duration.

There is mounting evidence that language users are sensitive to the distributional properties of multi-word sequences. Such findings expand the range of information speakers are sensitive to and call for processing models that can represent larger chains of relations. In the current paper we investigate the effect of multi-word statistics on phonetic duration using a combination of experimental and corpus-based research. We ask (a) if phonetic duration is affected by multi-word frequency in both elicited and spontaneous speech, and (b) if syntactic constituency modulates the effect. We show that phonetic durations are reduced in higher frequency sequences, regardless of constituency: duration is shorter for more frequent sequences within and across syntactic boundaries. The effects are not reducible to the frequency of the individual words or substrings. These findings open up a novel set of questions about the interaction between surface distributions and higher order properties, and the resulting need (or lack thereof) to incorporate higher order properties into processing models.

The Role of Multiword Building Blocks in Explaining L1–L2 Differences

Why are children better language learners than adults despite being worse at a range of other cognitive tasks? Here, we explore the role of multiword sequences in explaining L1-L2 differences in learning. In particular, we propose that children and adults differ in their reliance on such multiword units (MWUs) in learning, and that this difference affects learning strategies and outcomes, and leads to difficulty in learning certain grammatical relations. In the first part, we review recent findings that suggest that MWUs play a facilitative role in learning. We then discuss the implications of these findings for L1-L2 differences: We hypothesize that adults are both less likely to extract MWUs and less capable of benefiting from them in the process of learning. In the next section, we draw on psycholinguistic, developmental, and computational findings to support these predictions. We end with a discussion of the relation between this proposal and other accounts of L1-L2 difficulty.

The Developmental Trajectory of Children's Auditory and Visual Statistical Learning Abilities: Modality-Based Differences in the Effect of Age.

Infants, children and adults are capable of extracting recurring patterns from their environment through statistical learning (SL), an implicit learning mechanism that is considered to have an important role in language acquisition. Research over the past 20 years has shown that SL is present from very early infancy and found in a variety of tasks and across modalities (e.g., auditory, visual), raising questions on the domain generality of SL. However, while SL is well established for infants and adults, only little is known about its developmental trajectory during childhood, leaving two important questions unanswered: (1) Is SL an early-maturing capacity that is fully developed in infancy, or does it improve with age like other cognitive capacities (e.g., memory)? and (2) Will SL have similar developmental trajectories across modalities? Only few studies have looked at SL across development, with conflicting results: some find age-related improvements while others do not. Importantly, no study to date has examined auditory SL across childhood, nor compared it to visual SL to see if there are modality-based differences in the developmental trajectory of SL abilities. We addressed these issues by conducting a large-scale study of childrens performance on matching auditory and visual SL tasks across a wide age range (5-12y). Results show modality-based differences in the development of SL abilities: while childrens learning in the visual domain improved with age, learning in the auditory domain did not change in the tested age range. We examine these findings in light of previous studies and discuss their implications for modality-based differences in SL and for the role of auditory SL in language acquisition.

More Than Words: The Role of Multiword Sequences in Language Learning and Use

The ability to convey our thoughts using an infinite number of linguistic expressions is one of the hallmarks of human language. Understanding the nature of the psychological mechanisms and representations that give rise to this unique productivity is a fundamental goal for the cognitive sciences. A long-standing hypothesis is that single words and rules form the basic building blocks of linguistic productivity, with multiword sequences being treated as units only in peripheral cases such as idioms. The new millennium, however, has seen a shift toward construing multiword linguistic units not as linguistic rarities, but as important building blocks for language acquisition and processing. This shift-which originated within theoretical approaches that emphasize language learning and use-has far-reaching implications for theories of language representation, processing, and acquisition. Incorporating multiword units as integral building blocks blurs the distinction between grammar and lexicon; calls for models of production and comprehension that can accommodate and give rise to the effect of multiword information on processing; and highlights the importance of such units to learning. In this special topic, we bring together cutting-edge work on multiword sequences in theoretical linguistics, first-language acquisition, psycholinguistics, computational modeling, and second-language learning to present a comprehensive overview of the prominence and importance of such units in language, their possible role in explaining differences between first- and second-language learning, and the challenges the combined findings pose for theories of language.

Can Mimicking Infants’ Early Experience Facilitate Adult Learning? A Critique of Hudson Kam (2017)

ABSTRACT Why do adults seem to struggle more than children in learning a second language, despite being better at a range of other cognitive skills? The source of L1-L2 differences in language learning is one of the most debated topics in the study of language. One hypothesis is that L1-L2 differences are primarily experience-based, with language learning abilities themselves showing a high degree of plasticity. Hudson-Kam (2018) recently presented findings that seem to go against this hypothesis: in five studies, adults failed to show better learning in a more infant-like environment. In this article, I offer a theoretical and empirical critique of these findings and outline some open questions for investigating experience-based explanations for L1-L2 differences. In short, the main critique has to do with how we define what infant-like (or child-like) learning is and how we identify which aspects of children’s experience facilitate which aspects of language learning.

Minding the Gaps: Literacy Enhances Lexical Segmentation in Children Learning to Read.

Can emergent literacy impact the size of the linguistic units children attend to? We examined childrens ability to segment multiword sequences before and after they learned to read, in order to disentangle the effect of literacy and age on segmentation. We found that early readers were better at segmenting multiword units (after controlling for age, cognitive, and linguistic variables), and that improvement in literacy skills between the two sessions predicted improvement in segmentation abilities. Together, these findings suggest that literacy acquisition, rather than age, enhanced segmentation. We discuss implications for models of language learning.

Reading between the words: The effect of literacy on second language lexical segmentation

There is evidence that the ability to segment an utterance into words improves with literacy, yet previous research makes it difficult to disentangle the effect of literacy from that of age or cognitive abilities. We tested the hypothesis that literacy increases lexical segmentation in a second language in a unique sample of adult illiterates learning to read in their second language, controlling for cognitive abilities and using a task that taps language processing rather than only metalinguistic awareness. Participants’ segmentation was correlated with first language reading at the beginning of an intensive literacy course for illiterate adults. At the end of the course, those learning to read for the first time benefited more in terms of their segmentation abilities. We discuss implications for models of second language learning.
