The Lexicon of Emoji? Conventionality Modulates Processing of Emoji.

Emoji have been ubiquitous in communication for over a decade, yet how they derive meaning remains underexplored. Here, we examine an aspect fundamental to linguistic meaning-making: the degree to which emoji have conventional lexicalized meanings and whether that conventionalization affects processing in real-time. Experiment 1 establishes a range of meaning agreement levels across emoji within a population; Experiment 2 measures accuracy and response times to word-emoji pairings in a match/mismatch task. In this experiment, we found that accuracy and response time both correlated significantly with the level of population-wide meaning agreement from Experiment 1, suggesting that lexical access of single emoji may be comparable to that of words, even out of context. This is consistent with theories of a multimodal lexicon that stores links between meaning, structure, and modality in long-term memory. Altogether, these findings suggest that emoji can allow a range of entrenched, lexicalized representations.

The In-Out Effect in the Perception and Production of Real Words.

The in-out effect refers to the tendency that novel words whose consonants follow an inward-wandering pattern (e.g., P-T-K) are rated more positively than stimuli whose consonants follow an outward-wandering pattern (e.g., K-T-P). While this effect appears to be reliable, it is not yet clear to what extent it generalizes to existing words in a language. In two large-scale studies, we sought to extend the in-out effect from pseudowords to real words and from perception to production. In Study 1, we investigated whether previously collected affective ratings for English and Dutch words were more positive for inward-wandering words and more negative for outward-wandering words. No systematic relationship between wandering direction and affective valence was found. In Study 2, we investigated whether inward-wandering words are more likely to occur in positive online consumer restaurant reviews written in English and Dutch, compared to negative reviews, and whether this association was stronger for food ratings than for decor ratings. Again, no systematic relationship between wandering direction and review rating emerged. We suggest that the affective states triggered by different consonantal wandering directions might be used as a cue for forming judgments in the absence of other information, but that wandering direction is too low in salience to drive the shape of words in the lexicon.

The rise and fall of behaviorism: The narrative and the numbers.

The history of 20th-century American psychology is often depicted as a history of the rise and fall of behaviorism. Although historians disagree about the theoretical and social factors that have contributed to the development of experimental psychology, there is widespread consensus about the growing and (later) declining influence of behaviorism between approximately 1920 and 1970. Because such wide-scope claims about the development of American psychology are typically based on small and unrepresentative samples of historical data, however, the question arises to what extent the received view is justified. This article aims to answer this question in two ways. First, we use advanced scientometric tools (e.g., bibliometric mapping, cocitation analysis, and term co-occurrence analysis) to quantitatively analyze the metadata of 119,278 articles published in American journals between 1920 and 1970. We reconstruct the development and structure of American psychology using cocitation and co-occurrence networks and argue that the standard story needs reappraising. Second, we argue that the question whether behaviorism was the "dominant" school of American psychology is historically misleading to begin with. Using the results of our bibliometric analyses, we argue that questions about the development of American psychology deserve more fine-grained answers.

The grammar of emoji? Constraints on communicative pictorial sequencing.

Emoji have become a prominent part of interactive digital communication. Here, we ask the questions: does a grammatical system govern the way people use emoji; and how do emoji interact with the grammar of written text? We conducted two experiments that asked participants to have a digital conversation with each other using only emoji (Experiment 1) or to substitute at least one emoji for a word in the sentences (Experiment 2). First, we found that the emoji-only utterances of participants remained at simplistic levels of patterning, primarily appearing as one-unit utterances (as formulaic expressions or responsive emotions) or as linear sequencing (for example, repeating the same emoji or providing an unordered list of semantically related emoji). Emoji playing grammatical roles (i.e., 'parts-of-speech') were minimal, and showed little consistency in 'word order'. Second, emoji were substituted more for nouns and adjectives than verbs, while also typically conveying nonredundant information to the sentences. These findings suggest that, while emoji may follow tendencies in their interactions with grammatical structure in multimodal text-emoji productions, they lack grammatical structure on their own.

Teachers' monitoring of students' text comprehension: can students' keywords and summaries improve teachers' judgment accuracy?

We investigated intra-individual monitoring and regulation in learning from text in sixth-grade students and their teachers. In Experiment 1, students provided judgments of learning (JOLs) for six texts in one of three cue-prompt conditions (after writing delayed keywords or summaries or without a cue prompt) and then selected texts for restudy. Teachers also judged their students' learning for each text, while seeing - if present - the keywords or summaries each student had written for each text, and also selected texts for restudy. Overall, monitoring accuracy was low (.10 for students, -.02 for teachers) and did not differ between cue-prompt conditions. Regulation, indexed by the correlation between JOLs and restudy selections, was significant (-.38 for students, -.60 for teachers), but was also not affected by cue-prompt condition. In Experiment 2, teachers judged students' comprehension of six texts without knowing the students' names, so that only the keywords and summaries, not prior impressions, could inform judgments. Again, monitoring accuracy was generally low (.06), but higher for keywords (.23) than for summaries (-.10). These results suggest that monitoring intra-individual differences in students' learning is challenging for teachers. Analyses of the diagnosticity and utilization of keywords suggest that these may contain insufficient cues for improving teacher judgments at this level of specificity.

Implied motion language can influence visual spatial memory.

How do language and vision interact? Specifically, what impact can language have on visual processing, especially related to spatial memory? What are typically considered errors in visual processing, such as remembering the location of an object to be farther along its motion trajectory than it actually is, can be explained as perceptual achievements that are driven by our ability to anticipate future events. In two experiments, we tested whether the prior presentation of motion language influences visual spatial memory in ways that afford greater perceptual prediction. Experiment 1 showed that motion language influenced judgments for the spatial memory of an object beyond the known effects of implied motion present in the image itself. Experiment 2 replicated this finding. Our findings support a theory of perception as prediction.

Eye movements reveal differences in children's referential processing during narrative comprehension.

Children differ in their ability to build referentially coherent discourse representations. Using a visual world paradigm, we investigated how these differences might emerge during the online processing of spoken discourse. We recorded eye movements of 69 children (6-11 years of age) as they listened to a 7-min story and concurrently viewed a display containing line drawings of the protagonists. Throughout the story, the protagonists were referenced by either a name (e.g., rabbit) or an anaphoric pronoun (e.g., he). Results showed that the probability of on-target fixations increased after children heard a proper name, but not after they heard an anaphoric pronoun. However, differences in the probability of on-target fixation at word onset indicate that the referents of anaphoric pronouns were anticipated by good comprehenders, but less so by poor comprehenders. These findings suggest that comprehension outcomes are related to the online processing of discourse-level cues that regulate the accessibility of entities.

The influence of direct and indirect speech on mental representations.

Language can be viewed as a set of cues that modulate the comprehender's thought processes. It is a very subtle instrument. For example, the literature suggests that people perceive direct speech (e.g., Joanne said: 'I went out for dinner last night') as more vivid and perceptually engaging than indirect speech (e.g., Joanne said that she went out for dinner last night). But how is this alleged vividness evident in comprehenders' mental representations? We sought to address this question in a series of experiments. Our results do not support the idea that, compared to indirect speech, direct speech enhances the accessibility of information from the communicative or the referential situation during comprehension. Neither do our results support the idea that the hypothesized more vivid experience of direct speech is caused by a switch from the visual to the auditory modality. However, our results do show that direct speech leads to a stronger mental representation of the exact wording of a sentence than does indirect speech. These results show that language has a more subtle influence on memory representations than was previously suggested.

Evidence of speckle in extreme-UV lithography.

Based on reflective optics at 13.5 nm, extreme-UV lithography is the ultimate top-down technique to define structures below 22 nm but faces several challenges arising from the discrete nature of light and matter. Owing to the short wavelength, mask surface roughness plays a fundamental role in the increase of speckle pattern contrast, compromising the uniformity of the printed features. Herein, we have used a mask with engineered gradient surface roughness to illustrate the impact that speckle has on the resulting photoresist pattern. The speckle increases the photoresist roughness, but surprisingly, only when the mask surface roughness is well above existing manufacturing capabilities.

Perceptual simulation in developing language comprehension.

We tested an embodied account of language proposing that comprehenders create perceptual simulations of the events they hear and read about. In Experiment 1, children (ages 7-13years) performed a picture verification task. Each picture was preceded by a prerecorded spoken sentence describing an entity whose shape or orientation matched or mismatched the depicted object. Responses were faster for matching pictures, suggesting that participants had formed perceptual-like situation models of the sentences. The advantage for matching pictures did not increase with age. Experiment 2 extended these findings to the domain of written language. Participants (ages 7-10years) of high and low word reading ability verified pictures after reading sentences aloud. The results suggest that even when reading is effortful, children construct a perceptual simulation of the described events. We propose that perceptual simulation plays a more central role in developing language comprehension than was previously thought.
