  1. Mario Bonato, Marco Zorzi & Carlo Umiltà (2013). Difficulty Matters: Unspecific Attentional Demands as a Major Determinant of Performance Highlighted by Clinical Studies. Behavioral and Brain Sciences 36 (6):680-681.
    The cognitive impairments shown by brain-damaged patients emphasize the role of task difficulty as a major determinant for performance. We discuss the proposal of Kurzban et al. in light of our findings on right-hemisphere–damaged patients, who show increasing awareness deficits for the contralesional hemispace when engaged with resource-consuming dual tasks. This phenomenon is readily explained by the assumption of unspecific depletable resources.

  2. Conrad Perry, Johannes C. Ziegler & Marco Zorzi (2013). A Computational and Empirical Investigation of Graphemes in Reading. Cognitive Science 37 (5):800-828.
    It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the graphemes to linguistically meaningful categories such as the onset, vowel, and coda of a syllable. Here, we present a model that learns to do this in English for strings (...)

  6. Ivilin Stoianov, Peter Kramer, Carlo Umiltà & Marco Zorzi (2008). Visuospatial Priming of the Mental Number Line. Cognition 106 (2):770-779.
    It has been argued that numbers are spatially organized along a "mental number line" that facilitates left-hand responses to small numbers, and right-hand responses to large numbers. We hypothesized that whenever the representations of visual and numerical space are concurrently activated, interactions can occur between them, before response selection. A spatial prime is processed faster than a numerical target, and consistent with our hypothesis, we found that such a spatial prime affects non-spatial, verbal responses more when the prime follows a (...)

  9. Gabriella Vigliocco & Marco Zorzi (1999). Contact Points Between Lexical Retrieval and Sentence Production. Behavioral and Brain Sciences 22 (1):58-59.
    Speakers retrieve words to use them in sentences. Errors in incorporating words into sentential frames are revealing with respect to the lexical units as well as the lexical retrieval mechanism; hence they constrain theories of lexical access. We present a reanalysis of a corpus of spontaneously occurring lexical exchange errors that highlights the contact points between lexical and sentential processes.

  10. Marco Zorzi & Carlo Umiltà (1999). Priming in Neglect is Problematic for Linking Consciousness to Stability. Behavioral and Brain Sciences 22 (1):174-175.
    O'Brien & Opie argue that (1) only explicit representations give rise to conscious experience, and (2) explicit representations depend on stable patterns of activation. In neglect patients, the stimuli presented to the neglected hemifield are not consciously experienced but exert causal effects on the processing of other stimuli presented to the intact hemifield. We argue that O'Brien & Opie cannot account for a nonconscious representation that is stable, as attested by the fact that it affects behavior, but is neither potentially (...)

  11. Marco Zorzi & Gabriella Vigliocco (1999). Compositional Semantics and the Lemma Dilemma. Behavioral and Brain Sciences 22 (1):60-61.
    We discuss two key assumptions of Levelt et al.'s model of lexical retrieval: (1) the nondecompositional character of concepts and (2) lemmas as purely syntactic representations. These assumptions fail to capture the broader role of lemmas, which we propose as that of lexical–semantic representations binding (compositional) semantics with phonology (or orthography).

    Dual-mechanism models of language maintain a distinction between a lexicon and a computational system of linguistic rules. In his target article, Clahsen provides support for such a distinction, presenting evidence from German inflections. He argues for a structured lexicon, going beyond the strict lexicon versus rules dichotomy. We agree with the author in assuming a dual mechanism; however, we argue that a next step must be taken, going beyond the notion of the computational system as specific rules applying to a (...)
