Bacon and Egeth (1994) have claimed that color singletons do not interfere with search for a shape singleton when, instead of using a singleton detection mode, participants are forced to use a feature search mode. Bacon and Egeth induced a feature search mode by adding different shape singletons to the display so that observers could not simply respond to uniqueness to find the target. We did e...

Bone mineral content of the mid forearm was measured by photon absorptiometry in 73 white singletons (36 boys, 37 girls) born between 18 and 43 weeks' gestation. Results obtained within two weeks of birth for liveborn infants were used to establish bone mineral deposition curves approximating normal in utero development. Results for stillborn infants indicated a retardation of bone mineralisati...

Evidence that salient feature singletons guide attention only when the target and the singleton frequently coincide has been taken to suggest that selection of singletons is under top-down control: Observers strategically use an attentional set sensitive to the singleton being a target. Changing the singleton-target (or singleton-distractor) coincidence also changes the opportunity for facilita...

The question whether attentional capture by salient visual stimuli is driven by bottom-up salience or is contingent on top-down task set is still under dispute. We show that the ability of size singletons to capture attention is determined by current search goals. Participants searched for small or large target singletons among medium-size distractors. Attentional capture by small or large size...

In an ERP experiment, we investigated whether a 'permanent' salient distractor changes the deployment of attention to target and nontarget singletons. Observers searched for a color target in a search array that mainly consisted of black vertical lines, but also always contained a line in a task-irrelevant color. Together with this distractor, a target or nontarget singleton was presented. Nont...

In the present contribution we sketch an interpretation of characterizing aspects processing taking place in Default Mode Network based on a formal logic model psychoanalytic theory. particular, apply logical structural Freudian Unconscious as described so-called Bi-Logic introduced by Chilean psychoanalyst I. Matte Blanco. We ground our proposal original concerning distinction between object a...
