Exudates as Landmarks Identified through FCM Clustering in Retinal Images

2020

The aim of this work was to develop a method for the automatic identification of exudates, using an unsupervised clustering approach. The ability to classify each pixel as belonging to an eventual exudate, as a warning of disease, allows for the tracking of a patient&rsquo

Constituent priming effects: Evidence for preserved morphological processing in healthy old readers

2009

How elderly adults process morphologically complex words is still a matter of controversy. The present study explored whether compound word recognition is affected by ageing. A group of young adults and a group of older healthy adults were tested on a lexical decision task. Compound words were presented primed by their first constituent (book-BOOKSHOP), their second constituent (shop-BOOKSHOP), or by an unrelated word (house-BOOKSHOP). Results revealed that morphological processing is fully preserved in advanced age and that the magnitude of the constituent priming effect was similar for young and older adults.

Prefix Stripping Re-Re-Revisited: MEG Investigations of Morphological Decomposition and Recomposition

2019

We revisit a long-standing question in the psycholinguistic and neurolinguistic literature on comprehending morphologically complex words: are prefixes and suffixes processed using the same cognitive mechanisms? Recent work using Magnetoencephalography (MEG) to uncover the dynamic temporal and spatial responses evoked by visually presented complex suffixed single words provide us with a comprehensive picture of morphological processing in the brain, from early, form-based decomposition, through lexical access, grammatically constrained recomposition, and semantic interpretation. In the present study, we find that MEG responses to prefixed words reveal interesting early differences in the la…
