Perceptual learning: Insight in sight
The Hebbian synapse and Hebb learning rule are familiar to those working on biological and machine learning. But Hebb's insights from over fifty years ago carry many other lessons in learning and may contribute to a more parsimonious taxonomy of the mechanisms involved.
متن کاملTowards cytokine insight in sight.
Commentary Towards cytokine insight in sight In a recent paper in the Lancet,' antibodies that neutralise the cytokine, tumour necrosis factor a (TNF-a), were reported to produce marked and somewhat sustained relief of symptoms in the immune mediated disease rheumatoid arthritis. This report lends hope that the neutralisation of cytokines may eventually be of therapeutic value in inflam-matory ...
متن کاملNew insight puts CRAF in sight as a therapeutic target.
By selectively depleting components of the RAF-MEK-ERK pathway in transgenic mice, it is now shown in 2 studies that CRAF is critical for signaling to MEK downstream of oncogenic Kras and that BRAF is not required.
متن کاملThe Role of Insight in Perceptual Learning: Evidence from Illusory Contour Perception
The distinction between gradual and abrupt improvement in performance is commonly made in behavioral studies of learning. The learning of perceptual and motor skills is often characterized by gradual, incremental improvement and is found not to generalize over stimulus manipulations such as change in retinal size or location. In contrast, marked improvement in performance can occur suddenly—a p...
متن کاملPerceptual Learning in Humans
Chapter 2 reports two experiments that examine perceptual learning in humans. In Experiment 1, participants received intermixed exposure to two similar compounds (AX, BX, AX, BX ...) and blocked exposure to a second pair of similar compounds (CY, CY... DY, DY...). Aversions established to AX and CY generalized less to BX than to DY. This confirms that intermixed exposure results in greater perc...
