TL;DR: The Whorf thesis on the relationship between language and thought is found to involve the following two propositions: different linguistic communities perceive and conceive reality in different ways and the language spoken in a community helps to shape the cognitive structure of the individual.

TL;DR: There is evidence that early mastery of the phonetic units of language requires learning in a social context, and neuroscience on early language learning is beginning to reveal the multiple brain systems that underlie the human language faculty.
TL;DR: The authors examines how the cognitive notion of attention has been employed in SLA and how it is understood in cognitive science and summarizes recent research on attention from cognitive and neuroscience approaches, and some reformulations of problems raised in SLAs related to attention are proposed.
Abstract: This paper examines how the cognitive notion of attention has been employed in SLA and how it is understood in cognitive science. It summarizes recent research on attention from cognitive and neuroscience approaches. Some reformulations of problems raised in SLA research related to attention are proposed. Current research offers detailed ideas about attention and its component processes. These ideas, elaborated theoretically and empirically in cognitive neuroscience, may help untangle some important but difficult issues in SLA. Early, coarse-grained conceptions of attention, such as the limited-capacity metaphor or the automatic versus controlled processing dichotomy, are recast into an integrated human attention system with three separate yet interrelated networks: alertness, orientation, and detection. This finer grained analysis of attention is employed in a model of the role of attention in SLA.
TL;DR: This paper found that bilinguals look briefly at distractor objects whose name in the irrelevant language was initially phonetically similar to the spoken word more often than they looked at a control distractor object.
Abstract: Bilingualism provides a unique opportunity for exploring hypotheses about how the human brain encodes language. For example, the “input switch” theory states that bilinguals can deactivate one language module while using the other. A new measure of spoken language comprehension, headband-mounted eyetracking, allows a firm test of this theory. When given spoken instructions to pick up an object, in a monolingual session, late bilinguals looked briefly at a distractor object whose name in the irrelevant language was initially phonetically similar to the spoken word more often than they looked at a control distractor object. This result indicates some overlap between the two languages in bilinguals, and provides support for parallel, interactive accounts of spoken word recognition in general.
TL;DR: It is shown that processing the syntax of language elicits the known substrate of linguistic competence, whereas algebraic operations recruit bilateral parietal brain regions previously implicated in the representation of magnitude, arguing against the view that language provides the structure of thought across all cognitive domains.
Abstract: A central question in cognitive science is whether natural language provides combinatorial operations that are essential to diverse domains of thought. In the study reported here, we addressed this issue by examining the role of linguistic mechanisms in forging the hierarchical structures of algebra. In a 3-T functional MRI experiment, we showed that processing of the syntax-like operations of algebra does not rely on the neural mechanisms of natural language. Our findings indicate that processing the syntax of language elicits the known substrate of linguistic competence, whereas algebraic operations recruit bilateral parietal brain regions previously implicated in the representation of magnitude. This double dissociation argues against the view that language provides the structure of thought across all cognitive domains.
