Abstract: Most cognitive psychological studies assume that participants in lab-based tasks maintain a single goal based on task instructions. However, people can be motivated by other factors, such as curiosity. We examined if people attend to seemingly ...
Zusammenfassung. In der Sondierreiz-Aufgabe von Posner und Boies (1971) muss mit zwei Fingern einer Hand eine Wahlreaktionsaufgabe (Primäraufgabe) bearbeit werden, während mit der anderen Hand eine Einfachreaktion auf zufällig eingestreute Sondierreize ...
High frequency oscillatory neural activities in the human brainAbstract. Synchronized neural activity in animal visual cortex in the frequency range above 20 Hz, the gamma band, has been proposed as a signature of temporal feature binding. More and more ...
Abstract. Three experiments with an arithmetic working memory task examine the object switch effect first reported by Garavan (1998; Garavan (1998), which was interpreted as evidence for a focus of attention within working memory. Experiments 1a and 1b ...
Abstract. The present study investigates bottom-up effects serving the optimal balance between focusing attention on relevant information and distractibility by potentially significant events outside the focus of attention. We tested whether distraction, ...
Abstract. In a series of event-related functional magnetic resonance studies, we consistently found activation in anterior prefrontal cortex related to visual dimension changes in singleton search tasks. I review these data and discuss possible ...
Abstract. We investigated whether threat words presented in attended (foveal) and in unattended (parafoveal) locations of the visual field are attention grabbing. Neutral (nonemotional) words were presented at fixation as probes in a lexical decision ...
Abstract. A series of distinct event-related potentials (ERPs) have been recorded from the scalp of human subjects as they switch from one task to another. It is possible that task switching may depend on different mechanisms depending on whether the ...
Abstract.Love, Rouder, and Wisniewski (1999) and Ripoll and Marty (2005) showed that subjects could process global properties very quickly in a same/different task on abstract visual scenes for which the conspicuity of local and global properties had ...
Three priming experiments investigated the role of attention and view changes when common objects were rotated in depth. Objects were shown in prime-probe trial pairs. Experiment 1 extended findings by Stankiewicz, Hummel, and Cooper (1998) showing that ...
Color-naming latencies to noncolor words and nonwords were faster when the onset or final phoneme of the displays corresponded to the onset or final phoneme of the color response. For example, for displays printed in red, the word rack and nonword rask, ...
Recent studies have shown that robust affective priming effects can be obtained when participants are required to categorize the targets on the basis of their valence, but not when participants are asked to categorize the targets on the basis of ...
Abstract. Models of attention and emotion have assigned a special status to the processing of threatening information: Facilitated attentional capture by threat and its prioritized processing would allow for swift and adequate action to potentially ...
Abstract. Humans are fundamentally limited in processing information from the outside world. This is particularly evident in the attentional blink (AB), the impaired ability to identify the second of two targets presented in close succession. We report ...
Abstract. This study investigated trial-to-trial modulations of the processing of irrelevant valence information. Participants (N = 126) responded to the frame color of pictures with positive, neutral, or negative affective content - a procedure known as ...
In task switching experiments, comparing performance with bivalent stimuli (affording both tasks) to univalent stimuli (affording one task) confounds the need to change focus between dimensions and stimulus-task binding, because bivalent stimuli require ...
In a visual search task using photographs of real faces, a target emotional face was presented in an array of six neutral faces. Eye movements were monitored to assess attentional orienting and detection efficiency. ...
Six experiments are reported investigating whether a discontinuity in colour can accrue attentional priority. In addition to a standard visual search paradigm, we examined the degree to which colour singletons and nonsingletons are susceptible to change ...
In two experiments, we investigated the hypothesis of Rowland and Shanks (2006a) that sequence learning of relevant information is resistant to variations in perceptual load. Under conditions of increased selection difficulty, participants incidentally ...
Recent evidence suggests that anticipation of negatively valenced pictures strongly increases interference exerted by the actual presentation of these pictures, while anticipation of positively valenced pictures leaves the impact of the actual ...
