Aims and objectives The study provides new insights into how bilingual speakers process semantically complex novel meanings in their native (L1) and non-native language (L2). Methodology The study employs an EEG method with a semantic decision task to novel nominal metaphors, novel similes, as well as literal and anomalous sentences presented in p...

Conference Paper
The paper reports on an experiment conducted to investigate the nature of speech sound perception in terms of cross-modal mappings between vowel sound stimuli and colour spectrum associations. The study is based on the assumptions stemming from research on synaesthesia, sound symbolism and non-modularity of human perception. The findings indicate t...

In this paper, we present a novel context-dependent approach to modeling word meaning, and apply it to the modeling of metaphor. In distributional semantic approaches, words are represented as points in a high dimensional space generated from co-occurrence statistics; the distances between points may then be used to quantifying semantic relationshi...

Individuals with developmental dyslexia have been characterized by problems with attentional orienting. In the current study, we specifically focused on possible changes in endogenous visual orienting that may be reflected in the electroencephalogram. A variant of the Posner cuing paradigm was employed with valid or invalid central cues that preced...

Previous electrophysiological research on human creative cognition has related creative ideation to increased activity in the alpha band, an effect which mainly reflects increased general attentional demands. Research on alpha unrelated to creativity has revealed different functional roles of the upper (semantic processes) and lower (attentional pr...
Article
Novel metaphoric sentences have repeatedly evoked larger N400 amplitudes than literal sentences, while investigations of the late positive complex (LPC) have brought inconsistent results, with reports of both increased and reduced amplitudes. In two experiments, we examined novel metaphor comprehension in Polish, using the same set of literal, nove...

The first and second authors contributed equally to this article and should be considered co–first authors. We regret this omission and any problems it may have caused.
Article
To acquire a new word, learners need to create its representation in phonological short-term memory (STM) and then encode it in their long-term memory. Two strategies can enable word representation in STM: universal segmentation and phonological mapping. Universal segmentation is language universal and thus should predict word learning in any langu...

Event related potentials (ERPs) have frequently been employed to investigate language comprehension. One of the best researched language-related ERP components is the N400, which is sensitive to various linguistic factors (e.g. plausibility, word frequency, predictability, word-level associations), and is therefore commonly referred to as an index...
Article
Full-text available
Though metaphoric language comprehension has previously been investigated with event-related potentials, little attention has been devoted to extending this research from the monolingual to the bilingual context. In the current study, late proficient unbalanced Polish (L1)–English (L2) bilinguals performed a semantic decision task to novel metaphor...
Conference Paper
Full-text available
In this paper, we present a novel application of a computational model of word meaning to capture human judgments of the linguistic properties of metaphoricity, familiarity, and meaningfulness. We present data gathered from human subjects regarding their ratings of these properties over a set of word pairs specifically designed to exhibit varying d...

Irony as a communicative phenomenon continues to puzzle. One of the key questions concerns cognitive and linguistic mechanisms underpinning irony comprehension. Empirical research exploring how much time people need to grasp irony as compared to literal meanings, brought equivocal answers. In view of the timespan-oriented-approach’ inconclusiveness...

Researching metaphor can be approached from various perspectives. Psycholinguistic views offer insight into how metaphoric expressions are comprehended during online tasks and whether online metaphor comprehension differs from literal language under-standing. Early psycholinguistic studies used reaction time methods, which allowed re-searchers to i...

The first psychotic episode is usually preceded by the decline in functioning as well as the occurrence of symptoms, which due to low intensity or short duration do not fulfil the criteria allowing for the recognition of delusions or hallucinations. Early intervention at this stage may prevent the development of psychosis or its onset. It is thus n...

A b s t r a c t Purpose: The present study is a pilot test designed to verify the Figurative Language Battery that we have developed to explore figurative language skills of individuals with aphasia. Material and methods: Eight left brain damaged patients and ten controls were tested using the battery. The battery consists of four parts, each of wh...

Schizophrenia is a complex mental illness which encompasses a wide range of disorders of varied etiology, developmental patterns and effects. Structural and functional brain abnormalities found in people suffering from schizophrenia, which lead to negative symptoms of the disease (Ho et. al 2003), as well as the phenomenon of the deficit of the inh...

An important question in language processing research is to what extent domain-general executive control influences language processing. Modulations of inhibition efficiency have been reported showing that when inhibitory control is heavily involved in one task, participants show a decrease in inhibitory control on a following task (decrease in inhibition efficiency). If the decrease in domain general inhibition efficiency can be experimentally induced and can influence language processing, it should not only be able to affect semantic processing in the native language but also across the native and non-native languages of bilinguals. In the current project, we want to examine whether a non-linguistic executive control task can influence semantic processing in both the within-language context (Study 1, native speakers of Polish) and cross-language context (Study 2, Polish learners of English). To this aims, we will use reaction times measures and electroencephalography (EEG).

A research project aiming at exploring irony processing patterns in the native (L1) and nonnative (L2) language of a language user.

Our aim is to investigate processes involved in conventional and novel metaphor comprehension as indexed by the N400 and LPC.
