The temporal order judgment paradigm: subcortical attentional contribution under exogenous and endogenous cueing conditions.
The role of subcortical attentional processing was investigated under exogenous and endogenous cueing conditions. As retinotectal projections arise predominantly from the nasal retina i.e., temporal hemifield, subcortical attention should be distributed asymmetrically under monocular viewing conditions with a temporal hemifield advantage. We compared the results of monocular and binocular viewi...
متن کاملExogenous attentional capture by subliminal abrupt-onset cues: evidence from contrast-polarity independent cueing effects.
In the present study, we tested whether subliminal abrupt-onset cues capture attention in a bottom-up or top-down controlled manner. For our tests, we varied the searched-for target-contrast polarity (i.e., dark or light targets against a gray background) over four experiments. In line with the bottom-up hypothesis, our results indicate that subliminal-onset cues capture attention independently...
متن کاملEndogenous superantigens shape response to exogenous superantigens.
Endogenous superantigen-mediated thymic negative selection resulted in a paucity of mature T cells bearing T-cell receptor (TCR) Vbeta8 in the periphery. Consequently, the magnitude of immune response to exogenous superantigen staphylococcal enterotoxin B, which activates TCR Vbeta8(+) T cells, was significantly reduced and conferred protection from superantigen-induced mortality.
متن کاملVisible propagation from invisible exogenous cueing.
Perception and performance is affected not just by what we see but also by what we do not see-inputs that escape our awareness. While conscious processing and unconscious processing have been assumed to be separate and independent, here we report the propagation of unconscious exogenous cueing as determined by conscious motion perception. In a paradigm combining masked exogenous cueing and appa...
متن کاملA Unified Theory of Exogenous and Endogenous Attentional Control
Although diverse, theories of visual attention generally share the notion that attention is controlled by some combination of three distinct strategies: (1) exogenous cueing from locallycontrasting primitive visual features, such as abrupt onsets or color singletons (e.g., Itti & Koch, 2001); (2) endogenous gain modulation of exogenous activations, used to guide attention to task relevant featu...
