  • Asymmetric Morphological Priming Among Inflected and Derived Verbs and Nouns in Greek 
    Loui, Sofia; Protopapas, Athanassios; Orfanidou, Eleni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The present study examined differences between inflectional and derivational morphology using Greek nouns and verbs with masked priming (with both short and long stimulus onset asynchrony) and long-lag priming. A lexical ...
  • Between‑word processing and text‑level skills contributing to fluent reading of (non)word lists and text 
    van Viersen, Sietske; Altani, Angeliki; De Jong, Peter F.; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Abstract Recent studies have shown that fluent reading of word lists requires additional skills beyond efficient recognition of individual words. This study examined the specific contribution of between-word processing ...
  • Beyond Word Recognition: The Role of Efficient Sequential Processing in Word- and Text-Reading Fluency Development 
    Romero, Sandra; Georgiou, George K; Altani, Angeliki; Gorgun, Guher; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2024)
    Purpose: Previous studies examining the inter-relations between serial and discrete naming with reading have found that the ability to efficiently process multiple items presented in a sequence (indexed by serial naming) ...
  • Cascaded Processing in Naming and Reading: Evidence from Chinese and Korean 
    Georgiou, George K; Cho, Jeung-Ryeul; Deng, Ciping; Altani, Angeliki; Romero, Sandra; Kim, Min-Young; Wang, Lei; Wei, Wei; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    Previous studies have shown that the ability to simultaneously process multiple items when these appear in serial format (called “cascaded” processing) is an important element of reading fluency. However, most evidence in ...
  • Cognitive Control Beyond Single-Item Tasks: Insights from Pupillometry, Gaze, and Behavioral Measures 
    Ziaka, Laoura; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    Cognitive control has been typically examined using single-item tasks. This has implications for the generalizability of theories of control implementation. Previous studies have revealed that different control demands are ...
  • Conflict Monitoring or Μulti-tasking? Tracking Within-Task Performance in Single-item and Multi-item Stroop Tasks 
    Ziaka, Laoura; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Cognitive control is applied in situations that require overriding a habitual and automatic response. The conflict monitoring hypothesis and the Expected Value of Control (EVC) theory as its extension posit a control system ...
  • Derivational suffixes as cues to stress position in reading Greek 
    Grimani, Aikaterini; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Background In languages with lexical stress, reading aloud must include stress assignment. Stress information sources across languages include word-final letter sequences. Here, we examine whether such sequences account ...
  • Development of early morphological awareness in Greek: Epilinguistic versus metalinguistic and inflectional versus derivational awareness 
    Diamanti, Vassiliki; Benaki, Argyro; Mouzaki, Angeliki; Ralli, Asimina; Antoniou, Faye; Papaioannou, Sophia; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    This cross-sectional study examined the development of morphological awareness in Greek children 4–7 years old. A distinction was adopted between epilinguistic control, evidenced in judgment tasks and indicative of elementary ...
  • Dyslexia and word reading problems

  • Dyslexia profiles across orthographies differing in transparency:An evaluation of theoretical predictions contrasting English and Greek 
    Diamanti, Vasiliki; Goulandris, Nata; Campbell, Ruth; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We examined the manifestation of dyslexia in a cross-linguistic study contrasting English and Greek children with dyslexia compared to chronological age and reading-level control groups on reading accuracy and fluency, ...
  • Dyslexia: Still Not a Neurodevelopmental Disorder 
    Protopapas, Athanassios; Parrila, Rauno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    We recently pointed out that there is no evidence to support the commonly held view that there is something wrong with the brains of children who have great difficulty learning to read. In response, it was argued that ...
  • Early rapid naming longitudinally predicts shared variance in reading and arithmetic fluency 
    Hoff, David Armas; Amland, Tonje; Melby-Lervåg, Monica; Lervåg, Arne; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    A number of cognitive factors have been suggested to underlie development in reading and arithmetic skills. Although the two domains are strongly linked, only a few studies have investigated the processes that are shared ...
  • Enhanced design matrix for task-related fMRI data analysis 
    Morante, Manuel; Kopsinis, Yannis; Chatzichristos, C; Protopapas, Athanassios; Theodoridis, Sergios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    In this paper, we introduce a novel methodology for the analysis of task-related fMRI data. In particular, we propose an alternative way for constructing the design matrix, based on the newly suggested Information-Assisted ...
  • Expanding horizons of cross-linguistic research on reading: The Multilingual Eye-movement Corpus (MECO) 
    siegelman, noam; Schroeder, Sascha; Acartürk, Cengiz; Ahn, Hee-Don; Alexeeva, Svetlana; Amenta, Simona; Bertram, Raymond; Bonandrini, Rolando; Brysbaert, Marc; Chernova, Daria; Da Fonseca, Sara Maria; Dirix, Nicolas; Duyck, Wouter; Fella, Argyro; Frost, Ram; Gattei, Carolina; Kalaitzi, Areti; Kwon, Nayoung; Lõo, Kaidi; Marelli, Marco; Papadopoulos, Timothy; Protopapas, Athanassios; Savo, Satu; Shalom, Diego; Slioussar, Natalia; Stein, Roni; Sui, Longjiao; Taboh, Analí; Tønnesen, Veronica; Usal, Kerem Alp; Kuperman, Victor (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    Scientific studies of language behavior need to grapple with a large diversity of languages in the world and, for reading, a further variability in writing systems. Yet, the ability to form meaningful theories of reading ...
  • From Individual Word Recognition to Word List and Text Reading Fluency 
    Altani, Angeliki; Protopapas, Athanassios; Katopodi, Katerina; Georgiou, George (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    This study aimed to examine (a) the developing interrelations between the efficiency of reading individually presented words (i.e., isolated word recognition speed) and the efficiency of reading multiword sequences (i.e., ...
  • How RAN stimulus type and repetition affect RAN’s relation with decoding efficiency and reading comprehension 
    Poulsen, Mads; Protopapas, Athanassios; Juul, Holger (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    Purpose: This study investigated how correlations between rapid automatized naming (RAN) and reading depend on characteristics of the stimuli. RAN tasks using stimuli with high phonological demands were predicted to be the ...
  • Immediate and Sustained Effects of Verbal Labels for Newly-Learned Categories 
    Fotiadis, Fotis A.; Protopapas, Athanassios (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    Labels for the categories have been found to facilitate learning by boosting accuracy. According to the label-feedback hypothesis this facilitation is due to a mechanism selectively sensitizing perceptual dimensions. To ...
