Abstract: Miller’s (1956, The magical number seven, plus or minus two: Some limits on our capacity for processing information. Psychological Review 63(2). 81–97) working memory (WM) capacity of around seven items, plus or minus two, was never found by usage-based linguists to be a recurrent pattern in language. Thus, it has not figured prominently in cognitive models of grammar. Upon reflection, this is somewhat unusual, since WM has been considered a fundamental cognitive domain for information processing in psychology, so one might have reasonably expected properties such as capacity constraints to be reflected in language use and structures derived from use. This paper proposes that Miller’s (1956) number has not been particularly productive in usage-based linguistics because it turns out to have been an overestimate. A revised WM capacity has now superseded it within cognitive science, a “magic number four plus or minus one” (Cowan 2001, The magical number 4 in short-term memory: A reconsideration of mental storage capacity. Behavioral and Brain Sciences 24(1). 87–185). This paper suggests, drawing on evidence from spoken language corpora and multiple languages, that a range of linguistic structures and patterns align with this revised capacity estimate, unlike Miller’s (1956), ranging from phrasal verbs, idioms, n-grams, the lengths of intonation units and some abstract grammatical properties of phrasal categories and clause structure.

Abstract: This paper introduces the Corpus of the Canon of Western Literature (Version 1.0), accompanied by a demonstration of its potential uses. The canon of western literature has been an important construct in the study of literature, long standing and long contested. It has been argued to represent many of the greatest works produced in the history of western literature. This corpus operationalizes the western canon based on Harold Bloom’s The Western Canon: The Books and School of the Ages (1994). The paper describes the development of the corpus, its organization and source material. Corpus procedures are applied to the corpus, such as word frequency analysis, lemmatization and keyness, to demonstrate its potential uses in culturomics and corpus stylistics, two interdisciplinary fields between the traditional and digital humanities, and the linguistic and literary approaches to literature. Culturomics is the study of culture and social psychology via the investigation of corpora of literature as cultural artefacts, while corpus stylistics is the application of corpus linguistics to traditional literary scholarship. The corpus introduced in this paper is open source and freely available.

Abstract: The oral language proficiency of students in early education is crucial as teachers draw on this as a resource when developing literacy. There is a need to better understand what this oral language resource consists of at school entry, particularly the ersity amongst children so as to address inequalities. This article reports a study on a key component of oral language, namely productive vocabulary. It profiles the oral language vocabulary in approximately 3.6 million words produced by a large s le of almost 800 children under the age of five. The results are reported in a productive vocabulary resource, structured as a list of 2767 vocabulary targets. This profile represents highly productive vocabulary presumably known by most children as well as more advanced vocabulary not part of every child’s oral language. The article demonstrates the pedagogical implications of this research in the context of the National Literacy Learning Progressions of the Australian National Curriculum.

Abstract: There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during tertiary education, a vocabulary of minimally 10,000 words is recommended, along with proficiency in academic vocabulary. A recent study of three universities in the United Kingdom concluded pedagogical intervention was required, since estimates indicated undergraduates knew fewer than 10,000 words. A subsequent study of a New Zealand university found students knew 16,000 words and pedagogical intervention was not required. The current study investigates 433 tertiary students at an Australian university to determine if students required vocabulary support. It contributes to a research record allowing for comparisons internationally, nationally, and over time. Methods employed included the Vocabulary Size Test/VST and Academic Vocabulary Test/AVT. Results indicate an average vocabulary size of 16,117 words, with academic vocabulary well-known.

Abstract: This article presents cpb - lex , a large-scale database of lexical statistics derived from children’s picture books (age range 0–8 years). Such a database is essential for research in psychology, education and computational modelling, where rich details on the vocabulary of early print exposure are required. C pb - lex was built through an innovative method of computationally extracting lexical information from automatic speech-to-text captions and subtitle tracks generated from social media channels dedicated to reading picture books aloud. It consists of approximately 25,585 types (wordforms) and their frequency norms (raw and Zipf-transformed), a lexicon of bigrams (two-word sequences and their transitional probabilities) and a document-term matrix (which shows the importance of each word in the corpus in each book). Several immediate contributions of cpb - lex to behavioural science research are reported, including that the new cpb - lex frequency norms strongly predict age of acquisition and outperform comparable child-input lexical databases. The database allows researchers and practitioners to extract lexical statistics for high-frequency words which can be used to develop word lists. The paper concludes with an investigation of how cpb - lex can be used to extend recent modelling research on the lexical ersity children receive from picture books in addition to child-directed speech. Our model shows that the vocabulary input from a relatively small number of picture books can dramatically enrich vocabulary exposure from child-directed speech and potentially assist children with vocabulary input deficits. The database is freely available from the Open Science Framework repository: este73c .

Abstract: The aim of this study is to explore the relationship between the forms of clause combination and their systematic patterns of explicit inter-clausal coherence. The study is conducted within the theoretical framework of the Adaptive Approach. The Adaptive Approach conceives of combined clauses as a hierarchy of conventionalized units for discourse coherence management. The grammatical properties of the different combined clauses determine their position on the hierarchy, and these properties are claimed to correlate with whether the construction is more, or less, of a cohesive unit for packaging multiple propositions. The study pursues the hypothesis that clauses higher on the hierarchy, being the more cohesive grammatical constructions, should tend to manage coherence between the propositions they combine (i.e. the clausal constituents) through fewer explicit discourse-pragmatic ties than the clauses considered less cohesive grammatical constructions. An analysis of cohesive ties in 450 combined clauses, representing 9 different English clause types, bears out these expectations. This is a significant result indicating that an inverse relationship exists between the level of grammatical integration and the frequency of inter-clausal cohesive ties. It is argued to be a quantifiable consequence of grammatical hierarchy, reflecting a continuum of coherence management from discourse to grammar.

Abstract: The recently discovered Chile Niño/Niña is an intrinsic coupled climate mode in the southeast Pacific, which influences both regional climate and marine ecosystem. Using Scale Interaction Experiment‐Frontier version 2 seasonal prediction system, it is shown that the Chile Niño/Niña can be skillfully predicted up to 3‐month lead. Although the occurrences and related climate impacts of the Chile Niño/Niña are captured by the prediction system, the predicted magnitudes are weaker than observations in the ensemble mean. Further analyses of the inter‐member relationships indicate that the Chile Niño/Niña predictability depends on how well the coastal ocean‐atmosphere‐land positive feedback among alongshore surface winds, coastal upwelling and the sea surface temperature anomalies is captured. The insufficient reproduction of this essential feedback is responsible for the underestimated magnitude. Therefore, accurately predicting the Chile Niño/Niña remains a challenge. Improving model resolution and ensemble size may be a key to enhancing prediction skills of the coastal climate modes along the eastern boundary upwelling systems.

Abstract: As a dominant climate mode of the southeast Indian Ocean, Ningaloo Niño/Niña has paramount impacts on regional climate and marine ecosystems. Using outputs from the latest phase of Coupled Model Intercomparison Project (CMIP6), we have systematically evaluated the simulation of Ningaloo Niño/Niña in the state‐of‐the‐art coupled models. Eighteen out of 28 CMIP6 models well reproduce the spatial pattern and seasonality of Ningaloo Niño/Niña, whereas the simulated litudes show large spread across the models. Main processes of the oceanic and atmospheric El Niño‐Southern Oscillation teleconnections and the coastal Bjerknes feedback are successfully captured by most of the CMIP6 models, but their uncertainties in the simulation are responsible for the inter‐model difference in litude. The CMIP6 models are also skillful in reproducing the regional climate impacts of Ningaloo Niño/Niña. Compared to Coupled Model Intercomparison Project Phase 5, a larger fraction of models in CMIP6 well reproduce the Ningaloo Niño/Niña, which provides a good hope for projecting its future changes.

Abstract: Australia has experienced increasing number of heatwave events (HWEs) in recent decades. This study aims to examine key synoptic features of austral summer HWEs over Australia during 1950/1951–2019/2020. Based on ERA5‐reanalysis and rotated empirical orthogonal functions, HWEs in Australia are categorized into four types according to where they often occur together: East Australia (EA), North Australia (NA), West Australia (WA) and Southeast Australia (SEA). Our results reveal that while anomalous anticyclones at 500 hPa level are the typical synoptic circulations responsible for HWEs of each subregion, their specific mechanisms differ between subregions. The atmospheric heat budget at 850 hPa level shows that anomalous diabatic heating promotes the onset of HWEs in each subregion. While anomalous vertical advection and adiabatic heating due to the anomalous subsidence play an important role in maintaining HWEs till their demise in NA, they only help trigger HWEs in EA, SEA and WA. Our results also suggest that anomalous advection of climatological mean temperature is important to both the onset and persistence of HWEs in EA and SEA, while it only helps sustain (trigger) HWEs in NA (WA). The advection of anomalous temperature also acts to trigger HWEs in EA, SEA and WA. On the surface, upward long‐wave radiation and sensible heat flux contribute to the development of HWEs, whereas both of them are reduced in SEA due to the enhanced anomalous cyclones near the surface and the decreased land–air temperature difference. These findings help improve understanding of the synoptic characteristics and distinctive mechanisms of HWEs in different subregions of Australia.

Abstract: Currently, the Arctic is undergoing a significant warming, which has exerted widespread impacts on global climate. Although many mechanisms responsible for the Arctic warming have been proposed, the impacts of the multi‐decadal change of tropical sea surface temperature receive little attention. Here we use numerical experiments to elucidate that the Indian Ocean (IO) warming may contribute to the Arctic warming. Through enhancing the Atlantic Meridional Overturning Circulation, the IO warming remotely induces more ocean heat transport from the North Atlantic to the Arctic. The resulted upper ocean warming dominates the surface warming in the Arctic. Additionally, despite the net negative contribution of the atmospheric heat transport, more warm air is conveyed into the Kara Seas, North Eurasia, and North America sectors, contributing to the local warming. The results propose a new mechanism to interpret the Arctic warming and indicate the important remote impacts of the tropical IO warming.
