Automatic morpheme identification in reading development: MEG evidence from Fast Periodic Visual Stimulation

Date: 

October, 2020

Venue: 

Society for the Neurobiology of Language (SNL) Annual Meeting, virtual edition, October 21-24, 2020

Morphemes are the smallest linguistic units that carry meaning (e.g., a complex word such as artist is composed of a stem, art-, and a suffix, -ist).

Implicit Statistical Learning in Fast Periodic Visual Stimulation

October, 2020

Venue: 

Society for the Neurobiology of Language (SNL) Annual Meeting, virtual edition, October 21-24, 2020

Research on the neural underpinnings of linguistic representations has recently received a methodological boost with an approach that capitalises on the principle of neural entrainment by combining Fast Periodic Visual Stimulation (FPVS) and electrophysiological recordings (e.g., Lochy, Van Belle, & Rossion, 2015).

Tracking the pace of reading with finger movements

Date: 

October, 2020

Venue: 

Words in the World (WoW) International Conference, 16-18 October 2020 (online)

This talk presents a preliminary analysis of the data from ReadLET, a project studying reading development in children. It is based on a new paradigm that our colleagues at CNR in Pisa are developing, based on finger tracking on a tablet as children read passages of text, aiming to evaluate children’s reading skills, how they change in development and what plays a role in the process.

A developmental database of eye movement measures during natural reading

Date: 

June, 2020

Venue: 

Summer Neurolinguistics School 2020, Center for Language and Brain at the National Research University Higher School of Economics (HSE), Moscow, Russia - held online 22-24 June 2020

A highly ecological ability such as reading is often investigated through non-ecological experimental paradigms. The present work aims at providing the community with an ecological tool for future research, a developmental database of eye movement measures during natural reading. Eye movements were recorded from a large sample of Italian developing readers (N=140), aged 8–11, as they read 12 multiline passages taken from story-books for children (1566 tokens and 762 distinct types). Eye-tracking data were also recorded from a group of skilled adult readers (N=33), for comparison.

A highly ecological ability such as reading is often investigated through non-ecological experimental paradigms. The present work aims at complementing this approach by providing the community with a developmental database of eye movement measures during natural reading. Eye movements were recorded from a large sample of Italian developing readers (N=140), aged 8–11, as they read 12 multi-lined passages taken from story books for children (1566 tokens and 762 distinct types). Eye-tracking data were also recorded from a group of skilled adult readers (N=33), for comparison.

Form, function, meaning. A study on the distribution of inflectional morphemes in Italian

Date: 

February, 2020

Venue: 

19th International Morphology Meeting - Vienna, Austria - 6-8 February 2020

On the one hand, inflectional morphology can encode semantic features, such as numerosity or sex; on the other, its has a functional role. The agreement of morphological features disambiguates the relations between constituents in sentence parsing, and reduces processing effort by favoring word predictions (Dye et al., 2017; Wicha et al., 2004). Ideally, those processes should be favored by consistency between form and features.

Processing of compound constituents: position-specificity and interpretability

Date: 

February, 2020

Venue: 

19th International Morphology Meeting, Vienna, Austria, 6-8 February 2020

Constituent morphemes within complex words are identified during visual word processing, and likewise the presence of real morphemes slows down pseudoword rejection. Previous studies suggest that the identification of constituents in compound words is, to a certain degree, position-independent, reflecting the fact that constituents can occur in any position within compounds across the language (e.g., boathouse - houseboat). However, some stems occur more often in the first position of a compound (e.g., doorstep, doorstop, doorknob, doorbell vs.

The role of semantics in learning morphological systems. An artificial lexicon experiment

Date: 

February, 2020

Venue: 

19th International Morphology Meeting - Vienna, Austria - 6-8 February 2020

Whereas lexical words can encode potentially any meaning about the referential world, inflectional morphology encodes only a limited set of semantic features. Such features are cross-linguistically consistent and seem closely related to salient aspects of the environment processed by core knowledge systems: Tense encodes time perception, Number encodes numerosity, Gender systems are often based on animacy. Why are some features constantly present across languages grammars? And why are others, such as color, never attested?

Early morphological decomposition: MEG evidence from Fast Periodic Visual Stimulation

Date: 

December, 2019

Venue: 

Workshop on Australiasian Magnetoencephalography (WAM), Sydney, Australia, December 10-13, 2019

Here we investigate the neural representation of morphemes, both stems and suffixes, in a Fast Periodic Visual Stimulation (FPVS) paradigm combined with MEG. We find that the brain automatically detects morphological structure in stimuli that are entirely made up of morphemes, but not in nonwords that contain only a stem, or only a suffix. Further exploration of the neural sources behind these sensor-level data will provide more refined spatial information on the brain mechanisms underlying morpheme identification.

The role of affixes in the visual identification of words and nonwords

Date: 

November, 2019

Venue: 

International Morphological Processing Conference (MoProc), Tübingen, Germany, November 4-7, 2019

The exact mechanisms that govern the visual identification of complex words (e.g., build-er) are not entirely clear. In particular, it is not obvious why the system would identify (pseudo–)morphemes in words that only have an appearance of morphological complexity (e.g., corn–er, iron–y). One hypothesis is that this phenomenon is driven by letter co–occurrence regularity - morphemes are also recurrent clusters of letters.
