    • Parsing a cognitive task : a characterization of the mind’s bottleneck 

      Sigman, Mariano; Dehaene, Stanislas (2005-02-08)
      Parsing a mental operation into components, characterizing the parallel or serial nature of this flow, and understanding what each process ultimately contributes to response time are fundamental questions in cognitive ...

    • Dynamics of the central bottleneck : dual-task and task uncertainty 

      Sigman, Mariano; Dehaene, Stanislas (2006-06-27)
      Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently ...

    • Delays without mistakes : response time and error distributions in dual-task 

      Kamienkowski, Juan Esteban; Sigman, Mariano (2008-09-12)
      Background: When two tasks are presented within a short interval, a delay in the execution of the second task has been systematically observed. Psychological theorizing has argued that while sensory and motor operations ...

    • The Spatial and Temporal Construction of Confidence in the Visual Scene 

      Graziano, Martín; Sigman, Mariano (2009-03-17)
      Human subjects can report many items of a cluttered field a few hundred milliseconds after stimulus presentation. This memory decays rapidly and after a second only 3 or 4 items can be stored in working memory. Here we ...

    • The brain’s router : a cortical network model of serial processing in the primate brain 

      Zylberberg, Ariel (2010-04-29)
      The human brain efficiently solves certain operations such as object recognition and categorization through a massively parallel network of dedicated processors. However, human cognition also relies on the ability to perform ...

    • Collective behavior in the spatial spreading of obesity 

      Gallos, Lazaros K.; Barttfeld, Pablo; Havlin, Shlomo; Sigman, Mariano; Makse, Hernán A. (2012-06-12)
      Obesity prevalence is increasing in many countries at alarming levels. A difficulty in the conception of policies to reverse these trends is the identification of the drivers behind the obesity epidemics. Here, we implement ...

    • Neural processing of emotional facial and semantic xxpressions in euthymic bipolar disorder (BD) and its association with theory of mind (ToM) 

      Ibañez, Agustín; Urquina, Diego; Petroni, Agustín; Baez, Sandra; Lopez, Vladimir; Nascimento, Micaela do; Herrera, Eduar; Guex, Raphael; Hurtado, Esteban; Blenkmann, Esteban; Beltrachini, Leandro; Gelormini, Carlos; Sigman, Mariano; Lischinsky, Alicia; Torralva, Teresa; Torrente, Fernando; Cetkovich, Marcelo; Manes, Facundo (2012-10-08)
      Background: Adults with bipolar disorder (BD) have cognitive impairments that affect face processing and social cognition. However, it remains unknown whether these deficits in euthymic BD have impaired brain markers of ...
