Ideomotor response and the neural representation of implied crying in the human brain
We describe an fMRI study demonstrating that, when an onomatopoeic word highly suggestive of implied crying is heard, significant activation occurs in the left inferior frontal gyrus, the left inferior parietal lobule close to the supramarginal gyrus, the left dorsolateral prefrontal cortex, the middle frontal gyrus close to the right premotor cortex, and the visual cortex. Hearing pronounceable nonwords that do not imply crying does not appear t…
Early mechanism of negativity bias
The negativity bias is the perceptual phenomena whereby an emotionally negative stimulus is processed faster than a positive or neutral stimulus. We used the attentional blink paradigm to investigate whether attentional resources are required to obtain the negativity bias. Positive, negative or neutral words were used as a preceding target (T1) and/or a subsequent target (T2). Experiment 1 showed that the negativity bias occurred, because the att…
Susceptibility of spatial and verbal working memory to demands of the central executive 1
We used a dual‐task paradigm to examine the degree to which domain‐specific spatial and verbal subsystems depend on the domain‐general central executive. Forty participants were asked to retain spatial or verbal information while performing a concurrent secondary task related to simple arithmetic. The secondary tasks consisted of three cognitive processes: single‐digit addition, a digit‐carrying operation, and digit reading. The single‐digit addi…
Long-Term Drifts in Individual Observers' Unique-Hue Spectral Loci
Unique-hue spectral loci were measured under conditions of neutral adaptation as part of a study of hue-response recovery following chromatic adaptation. Four observers adjusted the wavelength of the test-field until it appeared to be neither yellow nor blue (unique green) or neither red nor green (unique yellow and blue) in randomized sessions. The results showed that there were marked individual differences and long-term drifts in the unique-hu…
Visual Reaction Time as a Function of Target Size and Retinal Eccentricity in the Peripheral Visual Field
Using 2 well practiced Ss, visual reaction times were measured to targets of 4 sizes between 18 and 116 min of arc at a fixed luminance level of 93 log cd/m2. The targets were presented to 11 retinal loci: fovea and 10°, 20°, 30°, 40°, and 50° on both the nasal and the temporal side of the fovea along the horizontal meridian of the right eye. Reaction time decreased as a function of increasing target size and increased as a function of increasing…
