Predictive language processing: integrating comprehension and production, and what atypical populations can tell us.

Predictive processing, a crucial aspect of human cognition, is also relevant for language comprehension. In everyday situations, we exploit various sources of information to anticipate and therefore facilitate processing of upcoming linguistic input. In the literature, there are a variety of models that aim at accounting for such ability.

I know how you'll say it: evidence of speaker-specific speech prediction.

Most models of language comprehension assume that the linguistic system is able to pre-activate phonological information. However, the evidence for phonological prediction is mixed and controversial. In this study, we implement a paradigm that capitalizes on the fact that foreign speakers usually make phonological errors.

Foreign and Regional Languages Make You Less Deontological.

Previous studies have shown that foreign languages can change people's responses to moral dilemmas, making them more likely to choose harm (e.g., to kill one individual in order to save a few lives).

Trial-by-trial fluctuations of pre-stimulus alpha power predict language ERPs.

Anticipatory mechanisms are known to play a key role in language, but they have been mostly investigated with violation paradigms, which only consider what happens after predictions have been (dis)confirmed. Relatively few studies focused on the pre-stimulus interval and found that stronger expectations are associated with lower pre-stimulus alpha power. However, alpha power also fluctuates spontaneously, in the absence of experimental manipulations; and in the attention and perception domains, spontaneously low pre-stimulus power is associated with better behavioral performance and with event-related potential (ERPs) with shorter latencies and higher amplitudes.

Aging-related effects on the controlled retrieval of semantic information.

The efficient use of knowledge requires semantic control processes to retrieve context-relevant information. So far, it is well-established that semantic knowledge, as measured with vocabulary tests, does not decline with aging. Yet, it is still unclear whether controlled retrieval-the context-driven retrieval of very specific aspects of semantic knowledge-deteriorates in aging, following the same fate as other forms of cognitive control.

Inefficient speech-motor control affects predictive speech comprehension: atypical electrophysiological correlates in stuttering.

Listeners predict upcoming information during language comprehension. However, how this ability is implemented is still largely unknown. Here, we tested the hypothesis proposing that language production mechanisms have a role in prediction.

Language as a cue for social categorization in bilingual communities.

This registered report article investigates the role of language as a dimension of social categorization. Our critical aim was to investigate whether categorization based on language occurs even when the languages coexist within the same sociolinguistic context, as is the case in bilingual communities. Bilingual individuals of two bilingual communities, the Basque Country (Spain) and Veneto (Italy), were tested using the memory confusion paradigm in a 'Who said what?' task.

Exploring the ventral white matter language network in bimodal and unimodal bilinguals.

We used diffusion magnetic resonance imaging tractography to investigate the effect of language modality on the anatomy of the ventral white matter language network by comparing unimodal (Italian/English) and bimodal bilinguals (Italian/Italian Sign Language). We extracted the diffusion tractography measures of the Inferior Longitudinal fasciculus (ILF), Uncinate fasciculus (UF) and Inferior Fronto-Occipital fasciculus (IFOF) and we correlated them with the degree of bilingualism and the individual performance in fluency tasks. For both groups of bilinguals, the microstructural properties of the right ILF were correlated with individual level of proficiency in L2, confirming the involvement of this tract in bilingualism.

How the hand has shaped sign languages.

In natural languages, biological constraints push toward cross-linguistic homogeneity while linguistic, cultural, and historical processes promote language diversification. Here, we investigated the effects of these opposing forces on the fingers and thumb configurations (handshapes) used in natural sign languages. We analyzed over 38,000 handshapes from 33 languages.

Kinematic Evidence of Root-to-Shoot Signaling for the Coding of Support Thickness in Pea Plants.

Plants such as climbers characterized by stems or tendrils need to find a potential support (e.g., pole, stick, other plants or trees) to reach greater light exposure.

Cracking the code: a comparative approach to plant communication.

The linguistic behavior of humans is usually considered the point of reference for studying the origin and evolution of language. As commonly defined, language is a form of communication between human beings; many have argued that it is unique to humans as there is no apparent equivalent for it in non-human organisms. How language is used as a means of communication is examined in this essay from a biological perspective positing that it is effectively and meaningfully used by non-human organisms and, more specifically, by plants.

The coding of object thickness in plants: When roots matter.

Tendrils are clasping structures used by climbing plants to anchor and support their vines that coil around suitable hosts to achieve the greatest exposure to sunlight. Although recent evidence suggests that climbing plants are able to sense the presence of a potential stimulus in the environment and to plan the tendrils' movements depending on properties such as its thickness, the mechanisms underlying thickness sensing in climbing plants have yet to be uncovered. The current research set out to use three-dimensional kinematical analysis to investigate if and in what way the root system contributed to thickness sensing.

Dimensions of social categorization: Inside the role of language.

The present pre-registration aims to investigate the role of language as a dimension of social categorization. Our critical aim is to investigate whether language can be used as a dimension of social categorization even when the languages coexist within the same sociolinguistic group, as is the case in bilingual communities where two languages are used in daily social interactions. We will use the memory confusion paradigm (also known as the Who said what? task).

Can Plants Move Like Animals? A Three-Dimensional Stereovision Analysis of Movement in Plants.

In this article we adapt a methodology customarily used to investigate movement in animals to study the movement of plants. The targeted movement is circumnutation, a helical organ movement widespread among plants. It is variable due to a different magnitude of the trajectory (amplitude) exhibited by the organ tip, duration of one cycle (period), circular, elliptical, pendulum-like or irregular shape and the clockwise and counterclockwise direction of rotation.

Commonalities in alpha and beta neural desynchronizations during prediction in language comprehension and production.

The present study investigates whether predictions during language comprehension are generated by engaging the language production system. Previous studies investigating either prediction or production highlighted M/EEG desynchronization (power decrease) in the alpha (8-10 Hz) and beta (13-30 Hz) frequency bands preceding the target. However, it is unclear whether this electrophysiological modulation underlies common mechanisms.

On-line control of movement in plants.

At first glance, plants seem relatively immobile and, unlike animals, unable to interact with the surroundings or escape stressful environments. But, although markedly different from those of animals, movement pervades all aspects of plant behaviour. Here, we focused our investigation on the approaching movement of climbing plants, that is the movement they perform to reach-to-climb a support.

Speed-accuracy trade-off in plants.

Speed-accuracy trade-off (SAT) is the tendency for decision speed to covary with decision accuracy. SAT is an inescapable property of aimed movements being present in a wide range of species, from insects to primates. An aspect that remains unsolved is whether SAT extends to plants' movement.

Language can shape the perception of oriented objects.

Seeing an object is a natural source for learning about the object's configuration. We show that language can also shape our knowledge about visual objects. We investigated sign language that enables deaf individuals to communicate through hand movements with as much expressive power as any other natural language.

Foreign language effect in decision-making: How foreign is it?

It has been shown that decisions and moral judgments differ when made using native languages compared to foreign languages. Cross-linguistic differences appeared in foreign languages that monolinguals typically acquired in school and used neither routinely nor extensively. We replicated these differences with two populations of proficient, native bilinguals (Italian-Venetian; Italian-Bergamasque).

Language and motor processing in reading and typing: Insights from beta-frequency band power modulations.

Power modulations of the EEG activity within the beta-frequency band were investigated across silent-reading and copy-typing tasks featuring emotionally negative and neutral words in order to clarify the interplay between language and motor processing. In reading, a single desynchronization surfaced 200-600 ms after target presentation, with a stronger power-decrease in lower beta frequencies for neutral compared to negative words. The typing task revealed two distinct desynchronizations.

Hands show where things are: The close similarity between sign and natural space.

Many of the signs produced across sign languages are iconic, in the sense that they resemble the concepts they represent. We examined whether location, one of basic sign parameters along with handshape and movement, is systematically used for purposes of iconicity. Our findings revealed a mapping of vertical sign space that is exploited in its entirety for encoding typical locations in natural space.

Flexible control of movement in plants.

Although plants are essentially sessile in nature, these organisms are very much in tune with their environment and are capable of a variety of movements. This may come as a surprise to many non-botanists, but not to Charles Darwin, who reported that plants do produce movements. Following Darwin's specific interest on climbing plants, this paper will focus on the attachment mechanisms by the tendrils.

The developmental trend of transposed letters effects in masked priming.

In the current study, we investigated the development of transposed letter (TL) priming effects with masked priming. Recent studies have reported different and contrasting results concerning the age at which TL priming effects first appear and whether they tend to decline or increase with age. One of the aims of this study was to investigate the developmental trend of orthographic mechanisms underlying the TL effects in Italian.

One can be some but some cannot be one: ERP correlates of numerosity incongruence are different for singular and plural.

Humans can communicate information on numerosity by means of number words (e.g., one hundred, a couple), but also through Number morphology (e.
