<jats:title>Abstract</jats:title><jats:p>Linguistic categories can impact visual perception. For instance, learning that two objects have different names can enhance their discriminability. Previous studies have identified a typical pattern of categorical perception, characterized by faster discrimination of stimuli from different categories, a neural mismatch response during early visual processing (100–200 ms), and effects restricted to the right visual field. However, it remains unclear whether language affects perception online or through long‐term changes to mental representations in memory. To address this, we tested the impact of newly learned object categories with and without memory consolidation during sleep. We replicated the canonical pattern of categorical perception for categories that underwent consolidation. Without consolidation, linguistic categories still influenced early visual processing but with distinct neural dynamics. Therefore, we found evidence of both transient and long‐term effects of language on perception and conclude that memory consolidation plays a crucial role in shaping how linguistic categories modulate perception.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Can brief training on novel grammatical morphemes influence visual processing of nonlinguistic stimuli? If so, how deep is this effect? Here, an experimental group learned two novel morphemes highlighting the familiar concept of transitivity in sentences; a control group was exposed to the same input but with the novel morphemes used interchangeably. Subsequently, both groups performed two visual oddball tasks with nonlinguistic motion events. In the first (attentional) oddball task, relative to the control group, the experimental group showed decreased attention (P300) to infrequent changes in the morpheme‐irrelevant dimension (shape) but not the morpheme‐relevant dimension (motion transitivity); in the second (preattentive) oddball task, they showed enhanced preattentive responses (N1/visual mismatch negativity) to infrequent changes in motion transitivity but not shape. Our findings show that increasing attention to preexisting concepts in sentences through brief training on novel grammatical morphemes can influence both attentional and preattentive visual processing.</jats:p>

<jats:title>Abstract</jats:title><jats:p>When learning spoken second language (L2), words overlapping in form and meaning with one's native language (L1) help break into the new language. When nonsigning speakers learn a sign language as L2, such overlaps are absent because of the modality differences (L1: speech, L2: sign). In such cases, nonsigning speakers might use iconic form‐meaning mappings in signs or their own gestural experience as gateways into the to‐be‐acquired sign language. In this study, we investigated how both these phenomena may contribute jointly to the acquisition of sign language vocabulary by hearing nonsigners. Participants were presented with three types of signs in the Sign Language of the Netherlands (NGT): arbitrary signs, iconic signs with high or low gesture overlap. Signs that were both iconic and highly overlapping with gestures boosted learning most at first exposure, and this effect remained the day after. Findings highlight the influence of modality‐specific attributes supporting the acquisition of a signed lexicon.</jats:p>

<jats:title>Abstract</jats:title><jats:p>This study investigates whether audiovisual phonetic training with hand gestures encoding visible or nonvisible articulation features has a differential impact on learning second language sounds. Ninety‐nine Catalan–Spanish bilingual students were trained to differentiate English /æ/ and /ʌ/, which differ in the visible lip aperture and nonvisible tongue position, with training involving no gestures, gestures representing the lip aperture, or gestures representing the tongue position. Before, immediately after, and 1 week after the training, participants’ perception of the targets was assessed through a word‐identification task, and their production was tested through paragraph‐reading, picture‐naming, and word‐imitation tasks. Although all participants improved in perception and production, the lip hand gesture was more effective in adjusting lip aperture than the other two conditions in the paragraph‐reading and picture‐naming tasks. These results suggest that hand gestures encoding visible rather than nonvisible articulation features are more effective for improving second language pronunciation.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Color terms divide the color spectrum differently across languages. Previous studies have reported that speakers of languages that have different words for light and dark blue (e.g., Russian <jats:italic>siniy</jats:italic> and <jats:italic>goluboy</jats:italic>) discriminate color chips sampled from these two linguistic categories faster than speakers of languages that use one basic color term for blue (e.g., English <jats:italic>blue</jats:italic>). This effect has been reported to be disrupted when participants engaged in a verbal interference task, suggesting that active language use can modulate the linguistic category effect. The current study provided a stringent test of this hypothesis by examining color discrimination under verbal interference in bilinguals speaking Lithuanian (two blue categories) and Norwegian (one blue category). The results revealed that the language activated during verbal interference had a significant impact on bilinguals’ color discrimination. Specifically, Lithuanian–Norwegian bilinguals exhibited a color category effect only when performing the task under verbal interference in Lithuanian but not in Norwegian. This demonstrated, within the same individuals, the momentary effect of active language processing on color perception.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Second language acquisition theory has traditionally focused on the cognitive and psycholinguistic processes involved in additional language (L2) learning. In addition, research on learner psychology has primarily centered on learners’ cognitive abilities (e.g., aptitude and working memory) and internal traits or states (e.g., dispositions, motivations, and affect). Language learning behavior, however, has remained largely neglected and under‐theorized. To address this gap, this paper proposes the proactive language learning theory, which delineates the agentic and strategic behaviors that learners employ to learn an additional language. These behaviors include input‐seeking behavior, interaction‐seeking behavior, information‐seeking behavior, and feedback‐seeking behavior. This paper presents theoretical arguments supporting the proposal, describes the four behavioral dimensions of the theory, and outlines general hypotheses concerning the contextual and learner‐related antecedents of these behaviors and their effects on L2 outcomes. Finally, the potential implications of this theory for advancing our understanding of L2 learning and instruction are discussed.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Some listeners exhibit higher sensitivity to subphonemic acoustic differences (i.e., higher speech gradiency). Here, we asked whether higher gradiency in a listener's first language (L1) facilitates foreign language learning and explored the possible sources of individual differences in L1 gradiency. To address these questions, we tested 164 native Spanish speakers with different linguistic profiles. Speech gradiency was assessed via a Visual Analogue Scale task, and foreign language proficiency was assessed via an English vocabulary test. Possible sources of gradiency included domain‐general auditory acuity, overall exposure to spoken language (indexed by age), and exposure to phonological diversity. Control measures were collected to account for variables such as phoneme categorization consistency, working memory, and musical training. The results revealed a positive link between L1 speech gradiency and vocabulary acquisition in a foreign language over and above all other variables. L1 speech gradiency itself was predicted by domain‐general auditory acuity and overall exposure to spoken language.</jats:p>

<jats:title>Abstract</jats:title><jats:p>The temporal focus hypothesis (TFH) entails that individuals who value the past tend to conceptualize it in front, whereas individuals who value the future tend to map the future in front instead (de la Fuente et al., 2014). This varies as a function of culture, individual differences, and context. Here, we extend this line of inquiry by testing a contextual variable, namely COVID‐19 quarantine status, and an individual differences variable, namely future precautionary behavior towards COVID‐19. Contrary to what the TFH would predict, we show that participants map the future to a frontal position, regardless of individual attitudes and quarantine status. However, participants who displayed more future precautionary behavior were also more future‐focused than participants who displayed less such behaviour, but this did not predict their front–back mappings of the future. These findings suggest that individual differences may be stronger determinants of temporal focus than contextual variables.</jats:p>
