This study discusses how textbook educational approaches concerning Le Châtelier's principle (LCP) may hinder student comprehension and prediction of chemical equilibrium disturbances. Firstly, after summarising students' LCP erroneous assertions/explanations, a categorisation of the potential barriers that may originate student misunderstandings…

One of the most enduring questions in the field of bilingualism is whether bilingual infants and children initially have one language system or two. Research with adults indicates that, while bilinguals do not represent their languages in two fully encapsulated language systems, they are able to functionally differentiate their languages. This…

In the present article we provide evidence for the occurrence of transfer of conceptualization patterns in narratives of two German-Turkish bilingual groups. All bilingual participants grew up in Germany, but only one group is still resident in Germany (n = 49). The other, the returnees, moved back to Turkey after having lived in Germany for…

Recent research has indicated that conceptual development in a specific domain may not be independent of the way it is mapped linguistically. We explore this claim in the semantic domain of evidentiality by considering various sets of data from Turkish-speaking children between one and a half to six years. We present evidence for (1) the…

Small numbers are spontaneously associated with left space and larger numbers with right space (the SNARC effect), for example when classifying numbers by parity. This effect is often attributed to reading habits but a causal link has so far never been documented. We report that bilingual Russian-Hebrew readers show a SNARC effect after reading…

English, and presumably any natural language, contains a small group of expressions referring to species of things found in nature. These species are defined by their internal structure, determined by genetics in the case of living things and by chemical or physical properties in the case of others. The reference of these terms is determined by…

Previous cognitive science research demonstrates how the Agent-action-Objective (AaO) paradigm controls the cognitive processes of differentiation and integration. The present discussion advances the process to the fourth of five phases. Of the four dependent variables emerging at this stage, two are discussed: zero processing and variations in…

If we want students to read for meaning, we must test patterns based upon both reader and text comprehension. Testing patterns will yield an understanding of the student's conceptualization of linked facts and the student's relative comprehension of those patterns to the text's macro-concepts. (Author/DJD)

The aim of the present study was to determine whether processing of syntactic word information (lemma) is subserved by the same neural substrate as processing of conceptual or word form information (lexeme). We measured BOLD responses in 14 native speakers of German in three different decision tasks, each focussing specifically on one level of…

A discussion of agency looks at cross-linguistic evidence concerning the place of volition, animacy, and person in a model of agentivity. Two views of agentivity are presented as complementary rather than mutually contradictory. Data from Lhasa Tibetan that support a less restrictive notion of agency than is often assumed are presented. In this…

The question of what constitutes a minimal appropriate context for understanding a metaphor is examined through the relative effectiveness of three types of contextual priming for metaphor comprehension. All three produced immediate and automatic metaphor comprehension. The use of context to disambiguate both literal and nonliteral speech messages…

A lexicalist, or direct-mapping, view of the relationship between syntactic functions and surface syntactic relations and a link between semantic features and the assignment of arguments to syntactic functions are advocated. An experiment with 192 undergraduate students examines the issues as problems of language production. (SLD)

The second of three articles on the ways in which people formulate their observations, this paper begins with a discussion of the assumptions underlying analytical and class-based models of cognition. The analytical approach to the measurement of cognition is found to be inappropriate because human cognition, and consequently language processing…

This third of three articles on the ways in which people formulate their observations presents an analysis of the perspective or attitude dominating the discourse of an interview. The analysis is conducted according to a paradigm that views the speaker as the controller of discourse perspective. The relationships found in the analysis are…

A fundamental problem in language acquisition is determining how children learn the formal vocabulary of the adult grammar. A proposed solution is the Semantic Bootstrapping Hypothesis (SBH), which states that children infer the identity of syntactic entities such as "subject" in input based on the presence of semantic entities such as…
