Double dissociations are typically used to examine the modularity of the brain, and its effect on behaviour. This double dissociation method has typically been used within one modality. Tresch, Sinnamon & Seamon [1] found double dissociations in participants’ ability to recognize the form or location of an object. We adapted the paradigm of Tresch et al. to become a crossmodal task. In Experime...

The paper makes three points about the role of double dissociation in cognitive neuropsychology. First, arguments from double dissociation to separate modules work by inference to the best, not the only possible, explanation. Second, in the development of computational cognitive neuropsychology, the contribution of connectionist cognitive science has been to broaden the range of potential expla...

Double dissociated tachycardias: isorhythmic A-V dissociation at rapid atrial and ventricular rates" (2005).

Two cases of a dissociation between prosopagnosia and impaired capacity to match familiar faces were studied. Recognition of familiar faces recovered in the first patient, whereas prosopagnosia persisted in the second patient despite recovery of matching unfamiliar faces and other visuoperceptive skills. This double dissociation is discussed in relation to current views of prosopagnosia.

The electron capture dissociation (ECD) of metallo-supramolecular dinuclear triple-stranded helicate Fe(2)L(3)(4+) ions was determined by Fourier transform ion cyclotron resonance mass spectrometry. Initial electron capture by the di-iron(II) triple helicate ions produces dinuclear double-stranded complexes analogous to those seen in solution with the monocationic metal centers Cu(I) or Ag(I). ...
