Sparse coding theories suggest that the visual brain is optimized to encode natural visual stimuli to minimize metabolic cost. It is thought that images that do not have the same statistical properties as natural images are unable to be coded efficiently and result in visual discomfort. Conversely, artworks are thought to be even more efficiently processed compared to natural images and so are esthetically pleasing. This project investigated visual discomfort in uncomfortable images, natural scenes, and artworks using a combination of low-level image statistical analysis, mathematical modeling, and EEG measures. Results showed that the model response predicted discomfort judgments. Moreover, low-level image statistics including edge predictability predict discomfort judgments, whereas contrast information predicts the steady-state visually evoked potential responses. In conclusion, this study demonstrates that discomfort judgments for a wide set of images can be influenced by contrast and edge information, and can be predicted by our models of low-level vision, whilst neural responses are more defined by contrast-based metrics, when contrast is allowed to vary.

Feature-based models of sign language use distinctive features to describe the phonological structure of signs. We use near-minimal pairs and phonological phenomena like productivity and neutralisation in French Sign Language to show that the feature [web], which refers to the webbing part of the fingers, should be (re)introduced into the list of phonologically active features. In discussing potential cases of [web] in other sign languages and the impact on the shape of phonological inventories, we first offer an account of [web] in terms of a location feature in line with most traditional feature-geometry models. We then offer some speculations on why a more uniform characterisation of [web] and the features in the same subclass in terms of the orientation type results in more economical models.

Contrast, adversative and corrective can all be represented by er in Classical Chinese, but they are lexicalized respectively by er, danshi and ershi in Modern Chinese. The two lexicalization systems suggest that the opposition relations have commonalities as well as differences. In the framework of relevance theory and ‘three domains’, this study argues that the three opposition relations are in different cognitive domains, at different representational levels, and trigger different inferences, which accounts for their diverse lexicalizations in Modern Chinese. The opposition relations also have cognitive or metaphorical connections with each other, which justifies their unified actualization in Classical Chinese. The pragmatics-cognitive framework could also account for interlinguistic data.

Much like other social and nonsocial evaluations, estimates of numerical quantities are susceptible to comparative influences. However, numerical representations can take either a nonsymbolic (e.g., a grouping of dots) or a symbolic numerical form (e.g., Hindu–Arabic numerals), which each produce comparative biases in opposite directions. The current work takes a fine-grained curve fitting approach across a wide range of values to the investigation of their potential nonlinear influence in the context of a numerical estimation task. A series of 3 experiments (N = 1,613) showed how nonsymbolic standards produce linear contrastive patterns (Study 1), whereas symbolic numerical anchors show a cubic assimilative effect with a leveling off in strength for more extreme standards (Study 2). Sequential contrast from the previous patterns and assimilation to the previous response were found to be present and additive in the presence of both representations but were larger in absence of the symbolic numerical anchors (Study 3).

Right-Node Raising is generally considered to impose stricter identity conditions than other kinds of ellipsis, such as VP ellipsis, according to Hankamer & Sag 1976 and Hardt 1993. In this paper, we investigate voice mismatch in French Right-Node Raising (RNR) through a corpus study and two experiments. We show that RNR with voice mismatch can be found in a written corpus (frTenTen 2012) and that many examples involve coordination of a reflexive active and a short passive form. We suggest this is because semantic contrast (here, between self and external agent) plays a role according to Hartmann (2000) and Abeillé and Mouret (2010). We ran two acceptability judgement experiments to test voice mismatch and semantic contrast. We did not find any penalty for voice mismatch with VP ellipsis but an interaction with semantic contrast. We also found an effect of semantic contrast when coordinating an active and a passive VP without participle ellipsis. We conclude that voice mismatch is acceptable with RNR and propose a Head-driven Phrase-Structure Grammar (HPSG) analysis, following Chaves (2014) and Shiraïshi et al. (2019).

Previous experimental work on the processing of clausal ellipsis with contrastive remnants shows a Locality preference – DP remnants are preferentially paired with the most recently encountered DP correlate in the antecedent clause, even in the presence of contrastive prosody or semantic bias favouring a non-local correlate. The Locality effect has been argued to arise from the language processor consulting (default) information-structural representations when pairing remnants and correlates, yet direct evidence for the information structure hypothesis for Locality has been difficult to obtain. Estonian is a flexible word order language that optionally marks Contrastive Topics (CTs) syntactically, while allowing for the linear distance between a CT subject correlate and remnant to be held constant, in order to rule out a Recency explanation for the Locality effect. In an eye-tracking during reading experiment with case-disambiguated subject and object remnants in Estonian, we see asymmetries in the Locality preference (i.e. object advantage) following canonical Verb-second antecedent clauses and subject CT-marking Verb-third clauses. This provides novel evidence for fine-grained information-structural representations guiding the processing of contrastive ellipsis.

According to regulatory fit theory (Higgins, 2000), when people make decisions with strategies that sustain their regulatory focus orientation, they “feel right” about what they are doing, and this “feeling-right” experience then transfers to subsequent choices, decisions, and evaluations. The present research was designed to link the concept of regulatory fit to functional accounts of counterfactual thinking. In the present study, participants generated counterfactuals about their anagram performance, after which persistence on a second set of anagrams was measured. Under promotion framing (i.e., find 90% or more of all the possible words) upward counterfactual thinking in general elicited larger increases in persistence than did downward counterfactual thinking in general, but under prevention framing (i.e., avoid failing to find 90% or more of all the possible words) upward evaluation (comparing reality to a better reality) elicited larger increases in persistence than did upward reflection (focusing on a better reality), whereas downward reflection (focusing on a worse reality) elicited larger increases in persistence than did downward evaluation (comparing reality to a worse reality). In all, the present findings suggest that the generation of counterfactuals enhances the likelihood that individuals will engage in courses of action that fit with their regulatory focus orientation.

Young children often make pragmatic assumptions when learning new words. For example, they assume that a speaker who uses different words intends to refer to different things – the so-called principle of contrast. We used a standard disambiguation task to explore whether children’s assumptions about contrast depend on how much words differ. Three- to 6-year-olds heard pairs of words that differed in terms of the number, position, and types of phonological contrasts. Results indicate that children were less likely to disambiguate words differing by one phoneme than words differing by two or more phonemes, particularly when those one-phoneme differences were located at the beginning or end of the words (as in fim/vim). Overall, the findings suggest that children’s pragmatic assumptions about two contrasting words depend not only on if words differ, but also on how they differ.

We present two studies exploring how participants respond when a speaker contrasts two ideas, then expresses an ambiguous preference towards one of them. Study 1 showed that, when reading a speaker’s preference as text, participants tended to choose whatever was said last as matching the speaker’s preference, reflecting the recent-mention bias of anaphora resolution. In Study 2, we asked whether this pattern changed for audio versions of our stimuli. We found that it did not. We then asked whether observers used gesture to disambiguate the speaker’s preference. Participants watched videos in which two statements were spoken. Co-speech gestures were produced during each statement, in two different locations. Next, an ambiguous preference for one option was spoken. In ‘gesture disambiguating’ trials, this statement was accompanied by a gesture in the same spatial location as the gesture accompanying the first statement. In ‘gesture non-disambiguating’ trials, no third gesture occurred. Participants chose the first statement as matching the speaker’s preference more often for gesture disambiguating compared to non-disambiguating trials. Our findings add to the literature on resolution of ambiguous anaphoric reference involving concrete entities and discourse deixis, and we extend this literature to show that gestures indexing abstract ideas are also used during discourse comprehension.

This article examines a turning point in the history of the theory of phonological distinctive features. In Morris Halle’s (1959) The Sound Pattern of Russian, features are organized into a contrastive hierarchy designed to minimize the number of specified features. Redundancy rules, however, ensure that the resulting underspecification has no real phonological consequences and, in subsequent generative approaches to phonology, contrastive hierarchies were largely abandoned. We explore how Halle’s hierarchy would have been different if it had been based on phonological patterns such as voicing assimilation, and show that this reorganization makes plausible predictions about other aspects of Russian phonology. We conclude by pointing to recent work in which the concept of a contrastive hierarchy has been revived, illustrating the range of phenomena that this theoretical device can account for if minimizing specifications is not the primary concern.
