BACKGROUND AND PURPOSE Autopsy studies suggest that cerebral amyloid angiopathy (CAA) is associated with cognitive impairment and risk for dementia. We analyzed neuropsychological test data from a prospective cohort study of patients with CAA to identify the prevalence of cognitive impairment and its associations with brain magnetic resonance imaging features and the apolipoprotein E genotype. ...

We present a system to comprehend natural language that combines cognitive linguistics with known properties of human language processing. It is built on Embodied Construction Grammar (ECG) and the Soar cognitive architecture. Its core is a novel grounded semantic parser. Experiments show the system produces actionable meanings and fulfills ten cognitive criteria we set out.

BACKGROUND A number of studies have examined clinical factors linked to worse neuropsychological performance in late life depression (LLD). To understand the influence of LLD on cognition, it is important to determine if deficits in a number of cognitive domains are relatively independent, or mediated by depression- related deficits in a basic domain such as processing speed. METHODS Patients...

This paper presents a data-driven investigation of phonesthemes, phonetic units said to carry meaning associations, thus challenging the traditionally assumed arbitrariness of language. Phonesthemes have received a substantial amount of attention within the cognitive science literature on sound iconicity, but nevertheless remain a controversial and understudied phenomenon. Here we employ NLP te...

In sensorimotor activities, learning requires efficient information processing, whether in car driving, sport activities or human-machine interactions. Several factors may affect the efficiency of such processing: they may be extrinsic (i.e., task-related) or intrinsic (i.e., subjects-related). The effects of these factors are intimately related to the structure of human information processing....

Three discussion points are addressed from two perspectives: that of an anthropological tradition in cognitive science, and that of application--oriented natural language processing. From the cognitive perspective, knowledge of the world is not as influenced by linguistic semantics as we are tempted to think. From the applied NLP perspective, the distinction between world and lexical knowledge ...

The rhythmogram is the visual output of an algorithm developed by Todd and Brown which is characterised as a “multi-scale auditory model” consisting of a number of stages that are meant to emulate the response of the lower levels of the auditory system. The aim of the current study is to continue the author’s SIAM approach of employing a cognitive model, in combination with signal processing te...
