[Updated: 20200422]

Thank you for finding your way to this place - my research top-page! As homepage mentions, I’m trying to do some long-overdue spring-cleaning of all pages within this website.
For this page of brief project outlines, the main updates have been in relabeling and rearranging some of the projects. However, most of the project pages themselves are likely to remain under (re)construction for some time to come ... ... and currently focus on introducing some of the more relevant papers and presentations within the Output page.
While there is always some danger of it becoming a little muddled along the way (as in life, generally, I find), this page hopes to accomplish two rather modest goals.
The first goal is to introduce the main areas of my research with a collection of suitably longer words that, for the sake of retaining some academic credibility, elusively hint at some deeper and more serious life-stuff significances of my research, beyond merely being a pretty neat activity to engage in on rainy afternoons, although naturally, it is that too!
The second goal is to provide some signposts that might guide the more inquisitive and intrepid explorer on to venture even further along the pathways towards considerably more words about the different parts that, in their individual ways, try quite hard to sum up to be a bigger whole!

Overview
Comfortable in being little more than an advanced organizer, this part is really only listing up a few keywords of some relevance to my research.
The core is essentially just a whole bunch of questions about the nature of the mental lexicon, various aspects of lexical knowledge and visual word recognition, with particular emphasis on two-kanji compound words in the Japanese mental lexicon, touching on some of the quite fiddly stuff, like
mental lexicon, visual word recognition, lexical retrieval and representation of compound words from morphological perspective, Japanese lemma-unit model, connectionist modeling, Japanese lexical properties, Japanese lexicography, kanji instruction, Japanese word associations, lexical association network maps, Japanese writing system, typology of writing systems, writing systems research, human memory, psycholinguistics, cognitive science ... ...

Japanese lemma unit model (JLUM)
The Japanese lemma unit model is a localist connectionist model of the Japanese mental lexicon (Joyce, 1999a; 2002a; 2002b; 2004; Masuda & Joyce, 2018). It is an adaptation for the Japanese mental lexicon of a modified Chinese version of the multilevel interactive-activation framework proposed by Taft, Liu and Zhu (1999). The adaptation was initially proposed to account for the results of a series of constituent-morpheme priming experiments to investigate the lexical retrieval and representation of two-kanji compound words in the Japanese mental lexicon from a morphological perspective.
Once revision complete, the JLUM page will provide outlines of my doctoral research and subsequent studies, but, in the meantime, it lists the main papers of relevance at the Output page.

Japanese lexical properties database (JLPD)
The Japanese lexical properties database project has focused on developing an ontology of Japanese lexical properties (Joyce & Hodošček, 2014) as a framework for constructing a large-scale lexical resource on the Japanese lexicon. As such, it will draw on a number of earlier and current projects to construct various component databases, such as ones of compound word morphology and semantic transparency (Joyce, Masuda, & Ogawa 2014; Masuda & Joyce, 2005, 2019; Masuda et at. 2012).
Once revision complete, the JLPD page will outline the ontology and many of the database components already worked on. The current version continues to make publicly available the Corpus Word Lists, reported on in Joyce, Hodošček & Nishina (2012), which were extracted from the BCCWJ corpus.

Japanese word association database (JWAD)
The word association task is undeniably one of the earliest methods of psycholinguistic research for investigating the nature of lexical knowledge and the structures of the mental lexicon. Its first reported use dates back to 1883, when Francis Galton insightfully recognized its potential for exploring the foundations of human thought. Despite its long tradition, however, it is also probably fair to say that psycholinguistics and cognitive science have yet to fully realize the word association task’s potential in mapping out the rich networks of associations that exist between words.
Once revision complete, the JWAD page will describe the project to construct a large-scale database of word association norms for basic Japanese vocabulary and to develop lexical association network maps as a means of visually representing the association data that can capture important aspects of words and their connectivity. However, for present, it lists the main papers of relevance at the Output page.

Japanese writing system (JWS)
The Japanese writing system is frequently described as being the most complicated, the most complex, the most intricate, hardest, or simply the worst system of writing ever created (Coulmas, 1989; DeFrancis, 1989; Fischer 2001; Robinson, 1995; Sansom, 1928; Smith, 1996; Sproat, 2000; Yamada, 1967).
Although further revisions will be made in due course, the present JWS page briefly (1) traces out my arguments that, most meaningfully, kanji function as a morphographic writing system (Joyce, 2011; which developed out of my doctoral thesis) and (2) outlines initial discussions of orthographic representation and variation within the JWS, based on Joyce, Hodošček & Nishina (2012). As soon as possible, further revisions will also describe the notion of intentionality espoused by Joyce & Masuda (2019) as framework for the motivational factors that underlie both the conventional orthographic and non-conventional, or variant, written representations of the JWS. The page also lists the main papers of relevance at the Output page.

Online research bibliography of written language and literacy (ORBWLL)
The online research bibliography of written language and literacy is an ongoing project to compile a comprehensive research resource for the wide spectrum of interests encompassed within written language and literacy research. Although focused on scripts, orthography, writing systems and written language, the research bibliography seeks to be interdisciplinary in nature, reflecting the diverse perspectives that inform this research, from diachronic studies, linguistic approaches, sociolinguistic considerations, pedagogical questions, technological matters, to psycholinguistic investigations and their related issues and concerns.
The ORBWLL page provides a brief overview of its gradual compilation and a link to the current version of the bibiography hosted within the AWLL’s website.

Writing systems research (WSR)
Writing systems research is about understanding the various ways that writing - as the most consequential invention or technology in human history - has been implemented by the various writing systems of the world. Accordingly, a central aspect of that research is to develop a typology of writing systems as a coherent framework or categorizing writing systems.
Once revision complete, the WSR page will discuss some of the conceptual and terminological issues for typologies (Joyce, 2016; Joyce & Borgwaldt 2011), but, in the meantime, it lists the main papers of relevance at the Output page.
