Any leftovers from a discarded prediction? Evidence from eye-movements during sentence comprehension
Gussow, Arella E.; Kapnoula, Efthymia C.; Molinaro, Nicola (Language, Cognition and Neuroscience, 2019)We investigated how listeners use gender-marked adjectives to adjust lexical predictions during sentence comprehension. Participants listened to sentence fragments in Spanish (e.g. “The witch flew to the village on her…”) ... -
Don’t force it! Gradient speech categorization calls for continuous categorization tasks
Apfelbaum, Keith S.; Kutlu, Ethan; McMurray, Bob; Kapnoula, Efthymia C. (ASA, 2022)Research on speech categorization and phoneme recognition has relied heavily on tasks in which participants listen to stimuli from a speech continuum and are asked to either classify each stimulus (identification) or ... -
Dynamic EEG analysis during language comprehension reveals interactive cascades between perceptual processing and sentential expectations
Sarrett, McCall E.; McMurray, Bob; Kapnoula, Efthymia C. (Brain and Language, 2020)Understanding spoken language requires analysis of the rapidly unfolding speech signal at multiple levels: acoustic, phonological, and semantic. However, there is not yet a comprehensive picture of how these levels relate. ... -
Effect of deep brain stimulation on vocal motor control mechanisms in Parkinson's disease
Behroozmand, Roozbeh; Johari, Karim; Kelley, Ryan M.; Kapnoula, Efthymia C.; Narayanan, Nandakumar S.; Greenleef, Jeremy D.W. (Parkinsonism and Related Disorders, 2019)motor symptoms in Parkinson's disease (PD); however, its effect on vocal motor function has yielded conflicted and highly variable results. The present study investigated the effects of STN-DBS on the mechanisms of ... -
Gradient Activation of Speech Categories Facilitates Listeners’ Recovery From Lexical Garden Paths, But Not Perception of Speech-in-Noise
Kapnoula, Efthymia C.; Edwards, Jan; McMurray, Bob (Journal of Experimental Psychology: Human Perception and Performance, 2021)Listeners activate speech-sound categories in a gradient way, and this information is maintained and affects activation of items at higher levels of processing (McMurray et al., 2002; Toscano et al., 2010). Recent ... -
Idiosyncratic use of bottom-up and top-down information leads to differences in speech perception flexibility: Converging evidence from ERPs and eye-tracking
Kapnoula, Efthymia C.; McMurray, Bob (Brain and Language, 2021)Listeners generally categorize speech sounds in a gradient manner. However, recent work, using a visual analogue scaling (VAS) task, suggests that some listeners show more categorical performance, leading to less flexible ... -
Lexical and sublexical effects on visual word recognition in Greek: comparing human behavior to the dual route cascaded modell
Kapnoula, Efthymia C.; Protopapas, Athanassios; Saunders, Steven J.; Coltheart, Max (Language, Cognition and Neuroscience, 2017)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 ... -
Lip-Reading Enables the Brain to Synthesize Auditory Features of Unknown Silent Speech
Bourguignon, Mathieu; Baart, Martijn; Kapnoula, Efthymia C.; Molinaro, Nicola (The Journal of Neuroscience, 2020)Lip-reading is crucial for understanding speech in challenging conditions. But how the brain extracts meaning from, silent, visual speech is still under debate. Lip-reading in silence activates the auditory cortices, but ... -
On the Locus of L2 Lexical Fuzziness: Insights From L1 Spoken Word Recognition and Novel Word Learning
Kapnoula, Efthymia C. (Frontiers in Psychology, 2021)The examination of how words are learned can offer valuable insights into the nature of lexical representations. For example, a common assessment of novel word learning is based on its ability to interfere with other ... -

Reconciling the Contradictory Effects of Production on Word Learning: Production May Help at First, but It Hurts Later
Kapnoula, Efthymia C.; Samuel, Arthur G. (APA American Psychological Association, 2022)Does saying a novel word help to recognize it later? Previous research on the effect of production on this aspect of word learning is inconclusive, as both facilitatory and detrimental effects of production are reported. ... -
Spoken Word Recognition: A Focus on Plasticity
Kapnoula, Efthymia C.; Jevtović, Mina; Magnuson, James S. (Annual Reviews, 2024)Psycholinguists define spoken word recognition (SWR) as, roughly, the processes intervening between speech perception and sentence processing, whereby a sequence of speech elements is mapped to a phonological wordform. ... -
Voices in the mental lexicon: Words carry indexical information that can affect access to their meaning
Kapnoula, Efthymia C.; Samuel, Arthur G. (Journal of Memory and Language, 2019)The speech signal carries both linguistic and non-linguistic information (e.g., a talker’s voice qualities; referred to as indexical information). There is evidence that indexical information can affect some aspects of ... -
Wait long and prosper! Delaying production alleviates its detrimental effect on word learning
Kapnoula, Efthymia C.; Samuel, Arthur G. (Taylor & Francis, 2023)Recent work by Baese-Berk and Samuel (Baese-Berk, M. M., & Samuel, A. G. (2022). Just give it time: Differential effects of disruption and delay on perceptual learning. Attention, Perception, & Psychophysics, 84(3), 960–980.) ...
