SpaVerb-WN—A megastudy of naming times for 4562 Spanish verbs: Effects of psycholinguistic and motor content variables

Several studies have been carried out in various languages to explore the role of the main psycholinguistic variables in word naming, mainly in nouns. However, reading of verbs has not been explored to the same extent, despite the differences that have been found between the processing of nouns and verbs. To reduce this research gap, we present here SpaVerb-WN, a megastudy of word naming in Spanish, with response times (RT) for 4562 verbs. RT were obtained from at least 20 healthy adult participants in a reading-aloud task. Several research questions on the role of syllable frequency, word length, neighbourhood, frequency, age of acquisition (AoA), and the novel variable ‘motor content’ in verb naming were also examined. Linear mixed-effects model analyses indicated that (1) RT increase in with increasing word length and with decreasing neighbourhood size, (2) syllable frequency does not show a significant effect on RT, (3) AoA mediates the effect of motor content, with a positive slope of motor content at low AoA scores and a negative slope at high AoA scores, and (4) there is an interaction between word frequency and AoA, in which the AoA effect for low-frequency verbs gradually decreases as frequency increases. The results are discussed in relation to existing evidence and in the context of the consistency of the spelling–sound mappings in Spanish.

Analysis of Posters for Informing the Population via Social Media during Covid-19: Ukrainian Network

Objective. This study aims to determine the extent to which psycholinguistic variables are included in the analysis of the quality of directive posters on social media during Covid-19. Methods. The methods used in the study include analysis of the relevant scientific literature on the identification of psycholinguistic categories and variables relevant to the study; expert assessment of qualitative parameters of posters published on Facebook by official organizations; methods of descriptive statistics. Results. The analysis of 298 unique works conducted through Ukrainian network on Facebook revealed that the overall average quality of the publications is on the borderline between medium and high levels – 69.3% (by text parameters – 70.0%, graphic parameters – 68.6%). Conclusions. The study revealed that psycholinguistic variables such as readability, imageability, concreteness, conceptual familiarity, semantic size, name agreement, image agreement, visual complexity, typicality, image variability, authenticity of texts, processing fluency, etc. penetrate deeply related research on the creolized texts in various forms and interpretations. The quality of the posters on Facebook made by the official institutions operating in the field of health care is at the borderline between medium and high levels. These indicators are most in need of improvement on text parameters such as “Emphasis” and “Call to action”, as well as on graphical parameters such as “Presence of interactive graphic links” and “Understandability of illustration message without text”.

Heterogeneity of repetition abilities in logopenic variant primary progressive aphasia

ABSTRACT. The differential diagnosis of primary progressive aphasia (PPA) is challenging due to overlapping clinical manifestations of the different variants of the disease. This is particularly true for the logopenic variant of PPA (lvPPA), in which such overlap was reported with regard to impairments in repetition abilities. In this study, four individuals with lvPPA underwent standard neuropsychological and language assessments. The influence of psycholinguistic variables on their performance of in word, nonword and sentence repetition tasks was also specifically explored. Some level of heterogeneity was found in cognitive functions and in language. The four participants showed impairment in sentence repetition in which their performance was negatively affected by semantic reversibility and syntactic complexity. This study supports the heterogeneity of lvPPA with respect to the cognitive and linguistic status of participants. It also shows that sentence repetition is influenced not only by length, but also by semantic reversibility and syntactic complexity, two psycholinguistic variables known to place additional demands on phonological working memory.

Semantic variables both help and hinder word production: Behavioural evidence from picture naming

This research investigated how word production is influenced by six feature-based semantic variables (number of semantic features, intercorrelational density, number of near semantic neighbours, semantic similarity, typicality, and distinctiveness). We simultaneously investigated effects of the six semantic variables on spoken picture naming in a large group of participants (n = 87), while controlling for other psycholinguistic variables. Across analyses, number of semantic features was the most consistent predictor with a facilitatory effect on naming latency and accuracy. In addition, inhibitory effects were found on naming accuracy for intercorrelational density and on naming latency for distinctiveness. The facilitatory effect of number of semantic features is suggested to stem from stronger semantic activation with an increasing number of semantic features, which results in facilitated selection of the word’s lexical representation. In contrast, the inhibitory effect of intercorrelational density is most easily accounted for by increased competition at the lexical level. The mechanism underlying the inhibitory effect of distinctiveness is unclear. These findings indicate that future research on factors affecting word retrieval should also control for effects of number of semantic features, intercorrelational density, and distinctiveness. They also suggest that effects of the other semantic variables (e.g., semantic neighbours) reported in the literature were potentially overestimated due to insufficient control of other semantic and/or psycholinguistic variables.

Emotional Tone, Analytical Thinking, and Somatosensory Processes of a Sample of Italian Tweets During the First Phases of the COVID-19 Pandemic: Observational Study (Preprint)

BACKGROUND The COVID-19 pandemic is a traumatic individual and collective chronic experience, with tremendous consequences on mental and psychological health that can also be reflected in people’s use of words. Psycholinguistic analysis of tweets from Twitter allows obtaining information about people’s emotional expression, analytical thinking, and somatosensory processes, which are particularly important in traumatic events contexts. OBJECTIVE We aimed to analyze the influence of official Italian COVID-19 daily data (new cases, deaths, and hospital discharges) and the phase of managing the pandemic on how people expressed emotions and their analytical thinking and somatosensory processes in Italian tweets written during the first phases of the COVID-19 pandemic in Italy. METHODS We retrieved 1,697,490 Italian COVID-19–related tweets written from February 24, 2020 to June 14, 2020 and analyzed them using LIWC2015 to calculate 3 summary psycholinguistic variables: emotional tone, analytical thinking, and somatosensory processes. Official daily data about new COVID-19 cases, deaths, and hospital discharges were retrieved from the Italian Prime Minister's Office and Civil Protection Department GitHub page. We considered 3 phases of managing the COVID-19 pandemic in Italy. We performed 3 general models, 1 for each summary variable as the dependent variable and with daily data and phase of managing the pandemic as independent variables. RESULTS General linear models to assess differences in daily scores of emotional tone, analytical thinking, and somatosensory processes were significant (F_6,104=21.53, <i>P</i>&lt;.001, R²= .55; F_5,105=9.20, <i>P</i>&lt;.001, R²= .30; F_6,104=6.15, <i>P</i>&lt;.001, R²=.26, respectively). CONCLUSIONS The COVID-19 pandemic affects how people express emotions, analytical thinking, and somatosensory processes in tweets. Our study contributes to the investigation of pandemic psychological consequences through psycholinguistic analysis of social media textual data.

Animacy norms for 224 European Portuguese concrete words

Words are frequently used, for example, as stimuli in cognitive and linguistic research. Consideringthat there are various psycholinguistic variables known to influence word processing (e.g., frequency,concreteness), it is important to control for those variables. Recently, it has been reported that animacy(the characteristic of being a living/animate or a non-living/inanimate entity) also affects variouscognitive and linguistic processes. In fact, animacy has been found to be one of the best predictors offree recall. However, animacy is still an uncontrolled variable in most studies and information aboutthis variable is still, for the most part, absent. In this study, we provide animacy norms for a set of224 European Portuguese concrete words. Such data should provide Portuguese researchers a helpfultool to start considering this dimension in a systematic way in their research.

Greek word recognition by Greek readers and the DRC model

We evaluated the dual route cascaded (DRC) model of visual word recognition using Greek behavioural data on word and nonword naming and lexical decision, focusing on the effects of syllable and bigram frequency. DRC was modified to process polysyllabic Greek words and nonwords. The Greek DRC and native speakers of Greek were presented with the same sets of word and nonword stimuli, spanning a wide range on several psycholinguistic variables, and the sensitivity of the model to lexical and sublexical variables was compared to the effects of these factors on the behavioural data. DRC pronounced correctly all the stimuli and successfully simulated the effects of frequency in words, and of length and bigram frequency in nonwords. However, unlike native speakers of Greek, DRC failed to demonstrate sensitivity to word length and syllabic frequency. We discuss the significance of these findings in constraining models of visual word recognition.
