Altered negative priming in older subjects : First evidence from behavioral and neural level
Bauer, Eva; Gebhardt, Helge; Gruppe, Harald; Gallhofer, Bernd; Sammer, Gebhard (2012)The impact of aging on the negative priming (NP) effect has been subject of many studies using behavioral measures. Results are inconsistent and corresponding neural data do not exist. We were interested in, whether or not ... -

Kaletsch, Morten; Krüger, Britta; Pilgramm, Sebastian; Stark, Rudolf; Lis, Stefanie; Gallhofer, Bernd; Zentgraf, Karen; Munzert, Jörn; Sammer, Gebhard (2014)Much recent research has shown that personality disorders are associated with an altered emotion perception. Whereas most of this research was conducted with stimuli such as faces, the present study examined possible ... -

Effekte eines postoperativen kognitiven Trainings auf postoperative kognitive Defizite nach herzchirurgischen Operationen
Butz, Marius (2023-05)Hintergrund: Herzchirurgische Operationen gelten als Risikofaktor für postoperative kognitive Defizite (POCD), die die gesundheitsbezogene Lebensqualität beeinträchtigen und die Mortalität erhöhen können. Das Ziel dieser ... -
Der Einfluss von Blickrichtungsreizen auf die Aufmerksamkeitsausrichtung bei Schizophrenie
Lange, Philipp (2021)Die vorliegende Arbeit beschäftigte sich mit der Untersuchung der Aufmerksamkeitsausrichtung bei Schizophrenie unter Verwendung des Gaze-Cueing Paradigmas. Aufgrund des gewählten Studiendesigns konnte für die Schizophrenie ... -
Fractional anisotropy and peripheral cytokine concentrations in outpatients with depressive episode: a diffusion tensor imaging observational study
Sammer, Gebhard; Neumann, Elena; Blecker, Carlo; Pedraz-Petrozzi, Bruno (2022)Over the past few years, evidence of a positive relationship between inflammation and depression has grown steadily. The aim of the current study was to investigate whether such depression-related inflammation could also ... -
Functional connectivity in a monetary and social incentive delay task in medicated patients with schizophrenia
Hanewald, Bernd; Lockhofen, Denise Elfriede Liesa; Sammer, Gebhard; Stingl, Markus; Gallhofer, Bernd; Mulert, Christoph; Iffland, Jona Ruben (2023)Introduction: Numerous studies indicate impaired reward-related learning in individuals with schizophrenia, with various factors such as illness duration, medication, disease severity, and level of analysis (behavioral or ... -
Hemodynamic response pattern of spatial cueing is different for social and symbolic cues
Lockhofen, Denise Elfriede Liesa; Gruppe, Harald; Ruprecht, Christoph; Gallhofer, Bernd; Sammer, Gebhard (2014)Directional social gaze and symbolic arrow cues both serve as spatial cues, causing seemingly reflexive shifts of an observer s attention. However, the underlying neural substrates remain a point at issue. The present study ... -

Neuroimaging evidence for processes underlying repetition of ignored stimuli
Bauer, Eva; Gebhardt, Helge; Ruprecht, Christoph; Gallhofer, Bernd; Sammer, Gebhard (2012)Prolonged response times are observed with targets having been presented as distractors immediately before, called negative priming effect. Among others, inhibitory and retrieval processes have been suggested underlying ... -
Performance Level and Cortical Atrophy Modulate the Neural Response to Increasing Working Memory Load in Younger and Older Adults
Bauer, Eva; Sammer, Gebhard; Toepper, Max (2018)There is evidence that the neural response to increasing working memory (WM) load is modulated by age and performance level. For a valid interpretation of these effects, however, it is important to understand, whether and ... -
