“…Selective activation from LSF stimuli is consistent with anatomical evidence that these brain areas receive substantial magnocellular inputs [9,42,61], possibly as part of a phylogenetically old route specialised for the rapid processing of fear-related stimuli [21,41,50,56,59].…”

ABSTRACTTo investigate the impact of spatial frequency on emotional facial expression analysis, ERPs were recorded in response to low spatial frequency (LSF), high spatial frequency (HSF), and unfiltered broad spatial frequency (BSF) faces with fearful or neutral expressions, houses, and chairs. In line with previous findings, BSF fearful facial expressions elicited a greater frontal positivity than BSF neutral facial expressions, starting at about 150 ms after stimulus onset. In contrast, this emotional expression effect was absent for HSF and LSF faces. Given that some brain regions involved in emotion processing, such as amygdala and connected structures, are selectively tuned to LSF visual inputs, these data suggest that ERP effects of emotional facial expression do not directly reflect activity in these regions. It is argued that higher order neocortical brain systems are involved in the generation of emotion-specific waveform modulations. The face-sensitive N170 component was neither affected by emotional facial expression nor by spatial frequency information.Theme: Neural Basis of Behaviour Topic: Cognition

“…The use of accuracy as a potentially more sensitive measurement than RT has previously been noted by many authors. For instance, Santee and Egeth (1982) suggested that under the Bdata-limited^conditions (Norman & Bobrow, 1975) of briefly presented displays, accuracy measures are more sensitive to perceptual processes (see also Gellatly, Cole, Fox, & Johnson, 2003;Milliken & Tipper 1998;Rafal, Smith, Krantz, Cohen, & Brennan, 1990;Skarratt, Gellatly, Cole, Pilling, & Hulleman, 2014). Empirical support for this has come from Cole, Kuhn, Heywood, and Kentridge (2009), who showed that although color Bsingletons^do not automatically attract attention when RT is used to index capture, they do so when a Bone-shotĉ hange detection method is used.…”

Theory of mind is said to be possessed by an individual if he or she is able to impute mental states to others. Recently, some authors have demonstrated that such mental state attributions can mediate the Bgaze cueing^effect, in which observation of another individual shifts an observer's attention. One question that follows from this work is whether such mental state attributions produce mandatory modulations of gaze cueing. Employing the basic gaze cueing paradigm, together with a technique commonly used to assess mentalstate attribution in nonhuman animals, we manipulated whether the gazing agent could see the same thing as the participant (i.e., the target) or had this view obstructed by a physical barrier. We found robust gaze cueing effects, even when the observed agent in the display could not see the same thing as the participant. These results suggest that the attribution of Bseeing^does not necessarily modulate the gaze cueing effect.

“…On the basis ofvon Skramlik's findings, we would say, in the terms we have adopted, that human subjects are tetrageusic for his salt stimuli. Since forced-choice procedures were not used, however, von Skramlik's work cannot be regarded as conclusive by today's psychophysical standards (for a discussion offorced-choice efficacy, see Rafal, Smith, Krantz, Cohen, & Brennen, 1990). Nonetheless, his work suggests that the total number of neural signals encoding gustatory stimuli is small.…”

Weinvestigated the ability of subjects to discriminate sugars with a whole-mouth forced-choice paradigm, in which a standard solution was compared with a test solution of varied concentration. Discrimination probabilities were U-shaped functions of test concentration: for 6 subjects and pairwise combinations of fructose, glucose, and sucrose, discriminability always declined to chance over a narrow range oftest concentrations. At concentrattons s 100mM,maltose was indiscriminable from fructose but discriminable at higher concentrations for 4 subjects. By analogy with the monochromacy of night vision, whereby any two lights are indiscriminable when their relative intensities are suitably adjusted, we call the gustatory indiscriminability of these sugars monogeusia. The simplest account of monogeusia is that all information about the indiscriminable sugars is represented by a single neural signal that varies only in magnitude. The discriminability of maltose from the other sugars at higher concentrations is consistent with the hypothesis that maltose also activates a second gustatory code.
