  1. Change detection without awareness: Do explicit reports underestimate the representation of change in the visual system?Diego Fernandez-Duque & Ian Thornton - 2000 - Visual Cognition 7 (1):323-344.
    Evidence from many different paradigms (e.g. change blindness, inattentional blindness, transsaccadic integration) indicate that observers are often very poor at reporting changes to their visual environment. Such evidence has been used to suggest that the spatio-temporal coherence needed to represent change can only occur in the presence of focused attention. In four experiments we use modified change blindness tasks to demonstrate (a) that sensitivity to change does occur in the absence of awareness, and (b) this sensitivity does not rely on (...)

  2. Executive attention and metacognitive regulation.Diego Fernandez-Duque, Jodie A. Baird & Michael I. Posner - 2000 - Consciousness and Cognition 9 (2):288-307.
    Metacognition refers to any knowledge or cognitive process that monitors or controls cognition. We highlight similarities between metacognitive and executive control functions, and ask how these processes might be implemented in the human brain. A review of brain imaging studies reveals a circuitry of attentional networks involved in these control processes, with its source located in midfrontal areas. These areas are active during conflict resolution, error correction, and emotional regulation. A developmental approach to the organization of the anatomy involved in (...)

    An implicit measure of undetected change.Ian Thornton & Diego Fernandez-Duque - 2000 - Spatial Vision 14 (1):21-44.
    b>—Several paradigms (e.g. change blindness, inattentional blindness, transsaccadic integra- tion) indicate that observers are often very poor at reporting changes to their visual environment. Such evidence has been used to suggest that the spatio-temporal coherence needed to represent change can only occur in the presence of focused attention. However, those studies almost always rely on explicit reports. It remains a possibility that the visual system can implicitly detect change, but that in the absence of focused attention, the change does not (...)

    Brain Mechanisms of Cognitive Skills.Michael I. Posner, Gregory J. DiGirolamo & Diego Fernandez-Duque - 1997 - Consciousness and Cognition 6 (2-3):267-290.
    This article examines the anatomy and circuitry of skills that, like reading, calculating, recognizing, or remembering, are common abilities of humans. While the anatomical areas active are unique to each skill there are features common to all tasks. For example, all skills produce activation of a small number of widely separated neural areas that appear necessary to perform the task. These neural areas relate to internal codes that may not be observed by any external behavior nor be reportable by the (...)

  6. Attention metaphors: How metaphors guide the cognitive psychology of attention.Diego Fernandez-Duque & Mark L. Johnson - 1999 - Cognitive Science 23 (1):83-116.
    The concept of attention is defined by multiple inconsistent metaphors that scientists use to identify relevant phenomena, frame hypotheses, construct experiments, and interpret data. (1) The Filter metaphor shapes debates about partial vs. complete filtering, early vs. late selection, and information filtering vs. enhancement. (2) The Spotlight metaphor raises the issue of space‐ vs. object‐based selection, and it guides research on the size, shape, and movement of the attentional focus. (3) The Spotlight‐in‐the‐Brain metaphor is frequently used to interpret imaging studies (...)

  8. Cause and effect theories of attention: The role of conceptual metaphors.Diego Fernandez-Duque - 2002 - Review of General Psychology 6 (2):153-165.
    Scientific concepts are defined by metaphors. These metaphors determine what atten- tion is and what count as adequate explanations of the phenomenon. The authors analyze these metaphors within 3 types of attention theories: (a) --cause-- theories, in which attention is presumed to modulate information processing (e.g., attention as a spotlight; attention as a limited resource); (b) --effect-- theories, in which attention is considered to be a by-product of information processing (e.g., the competition meta- phor); and (c) hybrid theories that combine (...)

    Brain imaging of attentional networks in normal and pathological states.Diego Fernandez-Duque - 2001 - Journal of Clinical and Experimental Neuropsychology 23 (1):74-93.
    The ability to image the human brain has provided a new perspective for neuropsychologists in their efforts to understand, diagnose, and treat insults to the human brain that might occur as the result of stroke, tumor, traumatic injury, degenerative disease, or errors in development. These new ®ndings are the major theme of this special issue. In our article, we consider brain networks that carry out the functions of attention. We outline several such networks that have been studied in normal and (...)

    Explicit mechanisms do not account for implicit localization and identification of change: An empirical reply to Mitroff et al (2000).Diego Fernandez-Duque & Ian Thornton - 2003 - Journal of Experimental Psychology 29 (5).
    Several recent findings support the notion that changes in the environment can be implicitly represented by the visual system. S. R. Mitroff, D. J. Simons, and S. L. Franconeri (2002) challenged this view and proposed alternative interpretations based on explicit strategies. Across 4 experiments, the current study finds no empirical support for such alternative proposals. Experiment 1 shows that subjects do not rely on unchanged items when locating an unaware change. Experiments 2 and 3 show that unaware changes affect performance (...)

    “Feeling more regret than I would have imagined”: Self-report and behavioral evidence.Diego Fernandez-Duque - unknown
    People tend to overestimate emotional responses to future events. This study examined whether such affective forecasting errors occur for feelings of regret, as measured by self-report and subsequent decision-making. Some participants played a pricing game and lost by a narrow or wide margin, while others were asked to imagine losing by such margins. Participants who experienced a narrow loss reported more regret than those who imagined a narrow loss. Furthermore, those experiencing a narrow loss behaved more cautiously in a subsequent (...)

  14. Selective attention in early dementia of alzheimer type.Diego Fernandez-Duque - manuscript
    This study explored possible deficits in selective attention brought about by Dementia of Alzheimer Type (DAT). In three experiments, we tested patients with early DAT, healthy elderly, and young adults under low memory demands to assess perceptual filtering, conflict resolution, and set switching abilities. We found no evidence of impaired perceptual filtering nor evidence of impaired conflict resolution in early DAT. In contrast, early DAT patients did exhibit a global cost in set switching consistent with an inability to maintain the (...)
