چکیده

Previous research has suggested that human perception of mathematical expressions is based on syntactic structure. Here, we extend our understanding of how humans perceive algebraic equations in two ways. First, we examined the hypothesis that the internal representation used by experienced mathematicians is based on the phrasal structure of the parse tree. This was tested using a memory recognition task, and the results supported the hypothesis. Second, we explored how much experience with mathematics is necessary before such representations become established. Participants were young students with very little experience with algebra. Surprisingly, the students appeared to encode equations in a manner similar to experienced mathematicians.

Textuality of Idiomatic Expressions in Cameroon English

The meaning of an idiomatic expression cannot be transparently worked out from the meanings of its constituent words due to its figurative and unpredictable nature. Consequently, the syntactic composition and the structural paradigm of an idiomatic expression are supposed to be the same in every context. However, this is not the case in the institutionalized second language varieties of English...

Clitics in Dependency Morphology

Clitics are challenging for many theories of grammar because they straddle syntax and morphology. In most theories, cliticization is considered a phrasal phenomenon: clitics are affix-like expressions that attach to whole phrases. Constituency-based grammars in particular struggle with the exact constituent structure of such expressions. This paper proposes a solution based on catena-based depe...

Thermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure

The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...

Facial Expression Recognition Based on Anatomical Structure of Human Face

Automatic analysis of human facial expressions is one of the challenging problems in machine vision systems. It has many applications in human-computer interactions such as, social signal processing, social robots, deceit detection, interactive video and behavior monitoring. In this paper, we develop a new method for automatic facial expression recognition based on facial muscle anatomy and hum...

A Linearization-Based Theory of Non-Constituent Focus

In this paper, we argue, mainly on the basis of Japanese data, that we need a theory of focus in which a contiguous sequence of expressions that does not form a morphosyntactic constituent is allowed to serve as a single focus, rather than merely as a sequence of two or more foci, and then present such a theory within the framework of linearization-based HPSG. In the proposed theory, prosodic c...
