New Resource: LaDEC: Large database of English compounds

Words in the World collaborators Christina Gagne, Thomas Spalding, and Daniel Schmidtke announce the Large Database of English Compounds (LaDEC).

This open access paper presents the Large Database of English Compounds (LaDEC) which consists of 8000+ English compound words as well as various analyses using the database to examine various theoretical questions concerning the influence of semantics, orthography, morphology, and sentiment on compound word processing.

Upcoming Talk: There is a big gap in our understanding of reading fluency and the study of serial naming can help address it

On Monday July 22, 2019, Dr. Athanassios Protopapas (University of Oslo) will be giving a talk on word reading fluency at McMaster University in Hamilton, Ontario. This invited talk is hosted by The Reading Lab and the Centre for Advanced Research in Experimental and Applied Linguistics at McMaster. See the abstract below for more information.

All are welcome to attend!


Date: July 22, 2019

Time: 12 – 2pm

Location: LRW 4018 (through ARiEAL entrance at LRW 4020), McMaster University


Word list reading fluency is theoretically expected to depend mainly on single word reading speed. Yet the correlation between the two diminishes with increasing fluency, while fluency remains strongly correlated to serial digit naming. This suggests that multi-element sequence processing is an important component of fluency. When multiple stimuli to be named are presented simultaneously, the total naming time is shorter than when they are presented individually (termed “serial advantage”). Presumably, this occurs because one or more stimuli can be processed simultaneously, for example by one stimulus being mapped to its phonological representation while the previous one is articulated and the next one is visually perceived. This temporal overlap, termed “cascaded” processing, amounts to the parallel processing of multiple sequential stimuli along a serial pipeline.

I will present data from serial and discrete naming and reading tasks in different orthographies supporting the hypotheses that (a) these tasks pattern along distinct dimensions of performance concerning sequential vs. single-entity processing; (b) stimuli are amenable to cascaded processing to the extent they are individually processed as unmediated single chunks; and (c) the serial advantage is limited by the slowest processing component. The first hypothesis suggests that a distinct skill domain, beyond single word processing, underlies efficient processing of word sequences (i.e., fluency). The second hypothesis distinguishes between alphanumeric and nonalphanumeric naming and sets the context for the study of word reading fluency development. The third hypothesis suggests that as long as articulation is faster than the preceding cognitive steps then the serial advantage is largely determined by the duration of the spoken words, but articulation goes on to become the rate-limiting factor as word recognition speeds up during reading development.

Serial word reading aligns increasingly with the serial naming factor at higher grades, suggesting that word reading fluency is gradually dominated by skill in simultaneously processing multiple successive items (“cascading”), beyond automatization of individual words. This explains why discrete word reading is decreasingly correlated with word reading fluency as reading skill increases and why serial digit naming (i.e., RAN) is such a strong concurrent and longitudinal predictor of word reading fluency.

ICYMI: EEG Analysis Workshop & STEP@CCP 2019 Registration Competitions

May 2019 is a busy month for Words in the World co-sponsored events!

The Brock & SHARCNet EEG Analysis Workshop (May 6 – 10), held in St. Catharines, ON, and Spring Training in Experimental Psycholinguistics at the Centre for Comparative Psycholinguistics (May 13 – 18), held in Edmonton, AB, are both coming up fast.

We are pleased to once again be offering registration competitions for both events to eligible trainees. If you are a trainee of a Words in the World partner or collaborator, you are eligible to participate. Up to five (5) trainees will have their registration costs covered for each competition.

Please note, there are two separate competitions, one for each event. Eligible trainees can apply to both competitions.

The deadline to apply for both competitions is April 30, 2019. For competition rules and submission details, follow the links below:

2019 ERP Workshop Registration Competition

2019 STEP Registration Competition


Upcoming workshop: Brock University & SHARCNet: EEG Analysis Workshop

Brock University & SHARCNet’s annual EEG Analysis Workshop will be held at Brock University from May 6 – May 10, 2019. Words in the World is a proud co-sponsor of this event.

Join Sid Segalowitz, James Desjardins, and Stefon van Noordt for a week of lectures and hands-on experience with both traditional and cutting-edge EEG analysis. Time will also be available to discuss individual research projects.

The cost of registration is $150 for students and postdoctoral researchers, and $250 for faculty and professionals. The deadline to register is May 2, 2019, so don’t delay!

Students and postdoctoral researchers who are working with Words in the World partners and collaborators are eligible to participate in the EEG Analysis Registration Competition, which covers registration costs.
