Cognitive constraints on advance planning of sentence intonation

Pitch peaks tend to be higher at the beginning of longer than shorter sentences (e.g., ‘A farmer is pulling donkeys’ vs ‘A farmer is pulling a donkey and goat’), whereas pitch valleys at the ends of sentences are rather constant for a given speaker. These data seem to imply that speakers avoid dropping their voice pitch too low by planning the height of sentence-initial pitch peaks prior to speaking. However, the length effect on sentence-initial pitch peaks appears to vary across different types of sentences, speakers and languages. Therefore, the notion that speakers plan sentence intonation in advance due to the limitations in low voice pitch leaves part of the data unexplained. Consequently, this study suggests a complementary cognitive account of length-dependent pitch scaling. In particular, it proposes that the sentence-initial pitch raise in long sentences is related to high demands on mental resources during the early stages of sentence planning. To tap into the cognitive underpinnings of planning sentence intonation, this study adopts the methodology of recording eye movements during a picture description task, as the eye movements are the established approximation of the real-time planning processes. Measures of voice pitch (Fundamental Frequency) and incrementality (eye movements) are used to examine the relationship between (verbal) working memory (WM), incrementality of sentence planning and the height of sentence-initial pitch peaks.

Efficiency in shaping grammars

Hawkins (1994, 1999, 2004, 2014a) proposes a performance-grammar correspondence hypothesis, claiming that grammars can be shaped by processing systems with reference to the degree of preference in communication. Given that Hawkins’s proposal mainly highlights the role of efficiency in language comprehension, this paper demonstrates that parsing principles can also be employed to account for language production. Based on an analysis of the production mechanism behind multiple occurrences of the Chinese reflexive ziji ‘self’ in a single clause, it shows that the notion of intersubjectivity can sometimes play a significant role in sentence planning, in the sense that the Chinese reflexive assists speakers to produce an utterance in line with the principle of efficiency, which will in turn help hearers compute the intended meaning by identifying potential referents.

Neural signatures of syntactic variation in speech planning

Planning to speak is a challenge for the brain, and the challenge varies between and within languages. Yet, little is known about how neural processes react to these variable challenges beyond the planning of individual words. Here, we examine how fundamental differences in syntax shape the time course of sentence planning. Most languages treat alike (i.e., align with each other) the 2 uses of a word like “gardener” in “the gardener crouched” and in “the gardener planted trees.” A minority keeps these formally distinct by adding special marking in 1 case, and some languages display both aligned and nonaligned expressions. Exploiting such a contrast in Hindi, we used electroencephalography (EEG) and eye tracking to suggest that this difference is associated with distinct patterns of neural processing and gaze behavior during early planning stages, preceding phonological word form preparation. Planning sentences with aligned expressions induces larger synchronization in the theta frequency band, suggesting higher working memory engagement, and more visual attention to agents than planning nonaligned sentences, suggesting delayed commitment to the relational details of the event. Furthermore, plain, unmarked expressions are associated with larger desynchronization in the alpha band than expressions with special markers, suggesting more engagement in information processing to keep overlapping structures distinct during planning. Our findings contrast with the observation that the form of aligned expressions is simpler, and they suggest that the global preference for alignment is driven not by its neurophysiological effect on sentence planning but by other sources, possibly by aspects of production flexibility and fluency or by sentence comprehension. This challenges current theories on how production and comprehension may affect the evolution and distribution of syntactic variants in the world’s languages.

Planning of active and passive voice in German

This eye-tracking experiment investigated how morphological case affects German speakers’ descriptions of transitive events, specifically whether explicit case marking modulates speakers’ structural choices. To increase the production of non-canonical structures (passive, patient-initial active), we primed patients in event scenes with a red dot. Subject and object case in German are unambiguously marked on masculine nouns but not on feminine nouns. If explicit case marking requires more structural planning, we should find an effect of gender. For feminine nouns, speakers may start with the cued patient and continue with a passive or a patient-initial active sentence. However, analyses of syntactic choice, speech onset times and eye gaze revealed that gender and thus case marking had no effect on sentence planning

Initiation of utterance planning in response to pre-recorded and “live” utterances

In everyday conversation, interlocutors often plan their utterances while listening to their conversational partners, thereby achieving short gaps between their turns. Important issues for current psycholinguistics are how interlocutors distribute their attention between listening and speech planning and how speech planning is timed relative to listening. Laboratory studies addressing these issues have used a variety of paradigms, some of which have involved using recorded speech to which participants responded, whereas others have involved interactions with confederates. This study investigated how this variation in the speech input affected the participants’ timing of speech planning. In Experiment 1, participants responded to utterances produced by a confederate, who sat next to them and looked at the same screen. In Experiment 2, they responded to recorded utterances of the same confederate. Analyses of the participants’ speech, their eye movements, and their performance in a concurrent tapping task showed that, compared with recorded speech, the presence of the confederate increased the processing load for the participants, but did not alter their global sentence planning strategy. These results have implications for the design of psycholinguistic experiments and theories of listening and speaking in dyadic settings.

Early testing and formative evaluation of the Enablers of Change assessment and sentence planning tool for adults with convictions

The Enablers of Change assessment and sentence planning tool has been designed to assess the risks, needs, strengths and protective factors of adults with convictions. Developed by Interserve, a Community Rehabilitation Company (CRC) provider in England, the tool is an innovation. The first of its kind in the United Kingdom (UK) to operationalise the risk needs and responsivity model with the ‘good lives’ model and desistance principles for the general adult population of low to medium risk of harm individuals managed by CRCs. This article reports the development, early testing and formative evaluation of the tool and recommendations for its onward development. Given that such integration is regarded by many as the ‘holy grail’ of probation practice, this article is of international significance and will make an original contribution to the limited evidence base on operationalising desistance in the management of adults with convictions in the UK and other jurisdictions.

Unaccusativity in Sentence Production

Linguistic analyses suggest that there are two types of intransitive verbs: unaccusatives, whose sole argument is a patient or theme (e.g., fall), and unergatives, whose sole argument is an agent (e.g., jump). 1 Past psycholinguistic experiments suggest that this distinction affects how sentences are processed: for example, it modulates both comprehension processes ( Bever and Sanz 1997 , Friedmann et al. 2008 ) and production processes ( Kegl 1995 , Kim 2006 , M. Lee and Thompson 2004 , J. Lee and Thompson 2011 , McAllister et al. 2009 ). Given this body of evidence, it is reasonable to assume, as we do here, that this distinction is directly relevant to psycholinguistic theorizing. However, especially in production, exactly how this distinction affects processing is unknown, beyond the suggestion that unaccusatives somehow involve more complex processing than unergatives (see J. Lee and Thompson 2011 ). Here we examine how real-time planning processes in production differ for unaccusatives and unergatives. We build on previous studies on lookahead effects in sentence planning that show that verbs are planned before a deep object is uttered but not before a deep subject is uttered ( Momma, Slevc, and Phillips 2015 , 2016 ). (We use terms like deep subject in a theory-neutral fashion, with no intended commitment to a specific syntactic encoding.) This line of research sheds light on the broader issue of how the theory of argument structure relates to sentence production.
