    • Action-related properties of objects shape object representations in the ventral stream 

      Mahon, Bradford Z.; Milleville, Shawn C.; Negri, Gioia A. L.; Rumiati, Raffaella I.; Caramazza, Alfonso; Martin, Alex (Elsevier (Cell Press), 2007)
      The principles driving the organization of the ventral object-processing stream remain unknown. Here, we show that stimulus-specific repetition suppression (RS) in one region of the ventral stream is biased according to ...

    • Affect of the unconscious: Visually suppressed angry faces modulate our decisions 

      Almeida, Jorge; Pajtas, Petra E.; Mahon, Bradford Z.; Nakayama, Ken; Caramazza, Alfonso (Springer Nature, 2012)
      Emotional and affective processing imposes itself over cognitive processes and modulates our perception of the surrounding environment. In two experiments, we addressed the issue of whether nonconscious processing of affect ...

    • Category-Specific Organization in the Human Brain Does Not Require Visual Experience 

      Mahon, Bradford Z.; Anzellotti, Stefano; Schwarzbach, Jens; Zampini, Massimiliano; Caramazza, Alfonso (Elsevier BV, 2009)
      Distinct regions within the ventral visual pathway show neural specialization for nonliving and living stimuli (e.g., tools, houses versus animals, faces). The causes of these category preferences are widely debated. Using ...

    • Concepts and Categories: A Cognitive Neuropsychological Perspective 

      Mahon, Bradford Z.; Caramazza, Alfonso (Annual Reviews, 2009)
      One of the most provocative and exciting issues in cognitive science is how neural specificity for semantic categories of common objects arises in the functional architecture of the brain. More than two decades of research ...

    • Constraining Questions About the Organisation and Representation of Conceptual Knowledge 

      Mahon, Bradford Z.; Caramazza, Alfonso (Taylor & Francis (Routledge), 2003)
      In this article we assume a domain-specific organisation of conceptual knowledge and consider two questions: How does this architecture constrain further assumptions that might be made regarding (1) the organisation of ...

    • The Cumulative Semantic Cost Does Not Reflect Lexical Selection By Competition 

      Navarrete, Eduardo; Mahon, Bradford Z.; Caramazza, Alfonso (Elsevier, 2010)
      The cumulative semantic cost describes a phenomenon in which picture naming latencies increase monotonically with each additional within-category item that is named in a sequence of pictures. Here we test whether the ...

    • Differential Activity for Animals and Manipulable Objects in the Anterior Temporal Lobes 

      Anzellotti, Stefano; Mahon, Bradford Z.; Schwarzbach, Jens; Caramazza, Alfonso (Massachusetts Institute of Technology Press, 2011)
      Neuropsychological evidence has highlighted the role of the anterior temporal lobes in the processing of conceptual knowledge. That putative role is only beginning to be investigated with fMRI as methodological advances ...

    • Grasping with the eyes: The role of elongation in visual recognition of manipulable objects 

      Almeida, Jorge; Mahon, Bradford Z.; Zapater-Raberov, Veronica; Dziuba, Aleksandra; Cabaço, Tiago; Marques, J. Frederico; Caramazza, Alfonso (Springer Nature, 2013)
      Processing within the dorsal visual stream subserves object-directed action, whereas visual object recognition is mediated by the ventral visual stream. Recent findings suggest that the computations performed by the dorsal ...

    • The Role of the Dorsal Visual Processing Stream in Tool Identification 

      Almeida, Jorge Manuel; Mahon, Bradford Z.; Caramazza, Alfonso (Sage Publications, 2010)
      The dorsal visual processing stream subserves object-directed action, whereas the ventral visual processing stream subserves visual object recognition. Little is known about how information computed by dorsal-stream ...

    • Semantic Interference In A Delayed Naming Task: Evidence for the Response Exclusion Hypothesis 

      Janssen, Niels; Schirm, Walter; Mahon, Bradford Z.; Caramazza, Alfonso (American Psychological Association, 2008)
      In 2 experiments participants named pictures of common objects with superimposed distractor words. In one naming condition, the pictures and words were presented simultaneously on every trial, and participants produced the ...

    • The organization of conceptual knowledge: the evidence from category-specific semantic deficits 

      Caramazza, Alfonso; Mahon, Bradford Z. (Elsevier, 2003)
      Questions about the organization of conceptual knowledge in the human brain can be addressed by studying patients with category-specific semantic deficits: disproportionate and even selective impairment of conceptual ...

    • What drives the organization of object knowledge in the brain? 

      Mahon, Bradford Z.; Caramazza, Alfonso (Elsevier, 2011)
      Various forms of category-specificity have been described at both the cognitive and neural levels, inviting the inference that different semantic domains are processed by distinct, dedicated mechanisms. In this paper, we ...

    • The Word Class Effect in the Picture–word Interference Paradigm 

      Janssen, Niels; Melinger, Alissa; Mahon, Bradford Z.; Finkbeiner, Matthew; Caramazza, Alfonso (Taylor & Francis, 2010)
      The word class effect in the picture–word interference paradigm is a highly influential finding that has provided some of the most compelling support for word class constraints on lexical selection. However, methodological ...
