Abstract. The ability to identify and communicate emotions is essential to psychological well-being. Yet research focusing exclusively on emotion concepts has been limited. This study examined nouns that represent emotions (e.g., pleasure, guilt) in comparison to nouns that represent abstract (e.g., wisdom, failure) and concrete entities (e.g., flower, coffin). Twenty-five healthy participants completed a lexical decision task. Event-related potential (ERP) data showed that emotion nouns elicited less pronounced N400 than both abstract and concrete nouns. Further, N400 amplitude differences between emotion and concrete nouns were evident in both hemispheres, whereas the differences between emotion and abstract nouns had a left-lateralized distribution. These findings suggest representational distinctions, possibly in both verbal and imagery systems, between emotion concepts versus other concepts, implications of which for theories of affect representations and for research on affect disorders merit further investigation.

Overwhelming Evidence

A great bulk of research in the psycholinguistic literature has been dedicated to hemispheric organization of words. An overwhelming evidence suggests that the left hemisphere is primarily responsible for lexical processing. However, non-words, which look similar to real words but lack meaningful associations, is underrepresented in the laterality literature. This study investigated the lateralization of Turkish non-words. Fifty-three Turkish monolinguals performed a lexical decision task in a visual hemifield paradigm. An analysis of their response times revealed left-hemispheric dominance for non-words, adding further support to the literature. The accuracy of their answers, however, were comparable regardless of the field of presentation. The results were discussed in light of the psycholinguistic word processing views.

Since the study of Meyer and Schvaneveldt (1971), a large number of researches have shown facilitation effect in cognitive processing of a given word when it is preceded by a semantically (i.e. associatively) related word. In this study, we examined influence of association strength between context and target on visual word processing in Serbian language. Primary goal was to test cognitive relevance of the t-value and mutual information (MI) as measures of the association strength. The results showed that the mutual information affects response latencies in the visual lexical decision task: the higher the mutual information for two words (bigram), the shorter the reaction time. Contrariwise, cognitive relevance of the t-value as a measure of the words' association strength was not confirmed.

Bilingual Literature

Language-emotion link has been a subject of interest for several decades. It has been studied extensively both in the monolingual and bilingual literature. However, due to the numerous factors that are at play in bilingualism, i.e. age and context of acquisition, frequency of use, there is conflicting evidence regarding the emotional load of each language of bilinguals. A great bulk of evidence leans towards the L1 as the more emotional language. This study investigates the perceived emotionality in the late learned language. Our participants (N = 57) were late bilinguals who learned their second language (English) in formal contexts after their first language (Turkish). We used a lexical decision task in which the participants determined whether the visually presented emotion words were real words or non-words. In line with the literature, we report faster response times for positive than for negative words in both languages. Also, the results showed L1 superiority in word processing.

The Impact

Good reading comprehension is indispensable in many situations including contract-based transactions that have become so prevalent in our everyday lives. People with dyslexia often exhibit impairments in this important cognitive process. Although the effects of italics — a commonly used style for highlighting important content in a range of documents — and font in general, have been explored with behavioural measures, their impact on human brain dynamics remains poorly understood. Here, we used electroencephalography (EEG) to investigate the specific effects of italics in a sentence reading lexical decision task in adult dyslexics and an age-matched non-dyslexia group. Overall, the performance of dyslexics was worse. Cluster-based event-related potential (ERP) analysis revealed that brain responses within the first 300 ms following the decision stimulus differed in amplitude and spatial distribution between dyslexics and non-dyslexics when processing italicised text. An initial ERP component over occipitotemporal electrode sites started to differ between the groups as early as 167 ms following the onset of short italicised decision words. A subsequent ERP component over centrofrontal electrodes showed differences lasting until about 300 ms post-stimulus onset. Inter-individual amplitude differences in this centrofrontal neural signal were predictive of behavioural performance across participants, further highlighting the role of fast post-sensory linguistic processes in lexical decision making. Crucially, our findings emphasise the importance of choosing font style carefully to optimise word processing and reading comprehension by everyone.

Purpose Cognition and language difficulties are frequently reported in both children and adults with epilepsy. The majority of the existing research has focused on pediatric epilepsy, documenting impairments in learning, academics, and social–emotional functioning. In comparison, language deficits in younger and older adults with epilepsy have received less empirical attention. Given recently identified limitations in the extant literature regarding assessing epilepsy-related language problems in adults ( Dutta et al., 2018 ), the current exploratory study described in this research note investigated the cognitive–linguistic abilities of adults with focal or generalized types of epilepsy. Method Twelve participants with epilepsy and 11 age- and education-matched healthy controls completed a cognitive–linguistic test battery. Event-related potential (ERP) procedures were also employed to assess the integrity of neural activity supporting psycholinguistic processing in both groups using a lexical decision task. Results No significant performance differences between epilepsy and healthy control groups were noted on basic language tasks; however, group differences were evident on the more complex language measures, including spoken discourse. Even though both groups performed the lexical decision task similarly in terms of accuracy, individuals with epilepsy demonstrated longer reaction times and some atypical ERP characteristics compared to controls. Conclusion The cognitive–linguistic assessment and ERP findings suggested that, compared to neurotypical adults, individuals with epilepsy demonstrate slower processing times and greater difficulty with high-level language and spoken discourse production, despite performing within typical limits on basic language tests. Preliminary results from this research are significant in providing new knowledge about language functioning in adults with epilepsy.

Global Pandemic

Due to the global pandemic, behavioral sciences including psychology that have traditionally relied on face-to-face data collection methods are facing a crisis. Given these circumstances, the present study was designed as a web-based replication of the findings reported in Lee et al. (2019) on the relationship between print exposure measured by the Korean Author Recognition Test (KART) and online measures of word processing using the lexical decision task and offline measures of language ability. We used the PsychoPy3 and Pavlovia platform in which participants were presented with a series of tasks in an entirely web-based environment. We found that scores on the KART were correlated with scores on a measure of language skills as well as self-reported reading habits. In addition, KART scores modulated the word frequency effect in the lexical decision task such that participants with higher KART scores tended to have smaller frequency effects. These results were highly consistent with previous lab-based studies including Lee et al. indicating that web-based experimental procedures are a viable alternative to lab-based face-to-face experiments.
