The cart before the horse: When cognitive neuroscience precedes cognitive neuropsychology

When prognosis precedes diagnosis: putting the cart before the horse.

Cognitive Neuroscience and Neuropsychology

NeuroReport 5, 2381-2384 (1994) WHEN two concurrent sensorimotor tasks require separate responses, selection of the first response generally delays selection of the second. Dual-task performance was examined in four patients who had undergone surgical transection of the forebrain commissures including the corpus callosum. One light flash was presented to each visual field in succession, and pat...

Cognitive Neuroscience and Neuropsychology

The neural basis of auditory perception can be investigated non-invasively by recording event-related brain potentials (ERPs) during auditory stimulation.1 ERPs can be conceptualized as a sequence of components each with its own set of neural generators and reflecting different psychological functions.2 The ERP component termed the mismatch negativity (MMN) reflects a pre-attentive auditory dev...

Cognitive Neuroscience and Neuropsychology

In event-related potentials (ERPs) studies, recognition memory is associated with two positivities: one over parietal regions, and one over frontal regions. With nameable neutral stimuli, such as words or common objects, the parietal effect is usually left lateralized, and the frontal effect is usually right lateralized. We investigated the lateralization of these effects for nonnameable emotio...

structure. All three groups displayed negative transfer to random material in block 7, and positive transfer to block 8, which is constructed as blocks 1–6. The crucial test of transfer involves new material with different surface structure but the same abstract structure in blocks 9 and 10. The schizophrenic group showed no evidence of use of the abstract information in blocks 9 and 10, as was...
