Psychological Research Methods and Cognitive Psychology

Welcome

... to the homepage of the "Research Methods and Cognitive Psychology" group at the department of psychology of the University Bremen.

Much of our research deals with human action control and psychomotor, also in the context of multitasking - so if several tasks have to be processed simultaneously. In addition, we deal with the processing of presuppositions in linguistic usage as well as memory psychology questions. These fundamental scientific interests are rounded off by the transfer into the field of human factors and the processing of issues in the field of applied statistics. More about these topics can be found here or for reading in corresponding publications click here.

In teaching, the work group is responsible for student education in the areas of psychological research methods and statistics.

12.02.2024. In an interdisciplinary project with audio engineers and audiologists led by Melissa Ramírez (TH Köln), Heinrich Liesefeld has contributed to the development of a virtual-reality based approach to screen for spatial hearing disorders. The paper reporting on our progress is now accepted for publication in Trends in Hearing. https://doi.org/10.1177/23312165241235463 

26.01.2024: The paper “Building bridges: Visual search meets action control via inter-trial sequence effects” by Dominique Lamy (University of Tel Aviv), Christian Frings (University of Trier) and Heinrich Liesefeld has been accepted for publication in the Review of General Psychology. We selectively review research and theorizing on the as of yet relatively unconnected topics of visual search and action control and link the two research areas based on similarities in task design and a certain class of empirical findings: both research communities have accumulated knowledge on how the preceding trial influences performance on the current trial. We demonstrate how considering mechanisms well-studied in the respective other research community will advance our understanding of cognitive mechanisms in both areas. https://doi.org/10.1177/10892680241232626

18.01.2024: The surprising robustness of visual search against concurrent auditory distraction by Ananya Mandal (LMU Munich), Anna Liesefeld, and Heinrich Liesefeld (see 13.09.2023) has been selected as an Editor’s Choice article. That is, our paper is among the “most exciting new findings in psychological science, selected by APA Journal editors.” (https://www.apa.org/news/editors-choice). The article can be downloaded free of charge for the next 30 days: https://doi.org/10.1037/xhp0001168 The preprint is available here: https://doi.org/10.31234/osf.io/hnvdm

15.11.2023: An essential prerequisite for scientific discourse is that the participants understand each other. Unfortunately, this is often not the case, but researchers from different theoretical camps employ different terms for the same construct or the same term for different constructs. Initiated by the Research Group Handling Visual Distraction (speakers: Hermann J. Müller, LMU München, and Heinrich Liesefeld), an international team of researchers led by Heinrich Liesefeld and Dominique Lamy (Tel Aviv University) has tackled this problem for research on visual distraction. In extensive discussions, we identified and defined the most central terms in the debate. The resulting paper was now accepted for publication in Attention, Perception, & Psychophysics. It is not only a reference work for experts but also provides an easy entry point into the topic for junior researchers. https://doi.org/10.3758/s13414-023-02820-3

10.11.2023: Heinrich Liesefeld conducted a workshop on visual salience at the annual meeting of the DFG Priority Programme 2392 Visual Communication – Theoretical, Empirical, and Applied Perspectives. The goals of this half-day workshop were (a) to convey the basic definition and theoretical background on salience, (b) relate these to modern theories of visual attention, and (c) highlight several influences that were empirically shown to modulate salience effects. Based on this knowledge, stimuli from current studies by the workshop participants were jointly examined for variations in salience.

28.10.2023: The english version of the statistics textbook by Markus Janczyk and Roland Pfister (Trier) has been published with Springer as "Understanding inferential statistics. From A for significance test to Z for confidence interval".

13.9.2023: The article “The surprising robustness of visual attention against concurrent auditory distraction” von Ananya Mandal (LMU München), Anna Liesefeld und Heinrich Liesefeld was accepted for publication in the Journal of Experimental Psychology: Human Perception and Performance.  In this study, we discovered that visual search is not disrupted by auditory distraction except if we force participants to listen more carefully. https://doi.org/10.1037/xhp0001168

12.8.2023: The PD is an ERP component extracted from the EEG that has been associated with the inhibition of distracting stimuli and that plays an important role in the current debate on visual distraction. Initiated by the Research Group Handling Visual Distraction (speakers: Hermann J. Müller, LMU München, and Heinrich Liesefeld), an international team of researchers led by Nick Gaspelin (University of Missouri) and including Heinrich Liesefeld has compiled empirical findings and theoretical positions on the PD. The resulting review paper has now been accepted in the Journal of Cognitive Neuroscience.

12.7.2023: Survival-relevant information are better rememberd than other information. A new paper on the resource requirements of encoding such information written by Meike Kroneisen (Landau), Rika Groß (Mannheim), Edgar Erdfelder (Mannheim) and Markus Janczyk was accepted for publication in Psychonomic Bulletin and Review.

6.7.2023: Heinrich Liesefeld and Hermann Müller (LMU Munich) have published a commentary on a target article by Jan Theeuwes. We highlight once again that a salient distractor can interfere with visual search only if observers expect a salient target, and carve out differences and similarities with Theeuwes' new theory. https://doi.org/gsgdjx

30.6.2023: The 2nd funding phase of the DFG Research Unit FOR 2718 “Modal and Amodal Cognition: Functions and Interactions“ approved (Speaker: Prof. Dr. Barbara Kaup, University of Tübingen) was approved.

26.6.2023: How is the salience of irrelevant stimuli related to action control? The surprising answer is: It depends on the search mode! More information on this study will be available soon in a paper by Philip Schmalbrock, Christian Frings (both at University of Trier) and Heinrich Liesefeld that was accepted for publication in the Journal of Experimental Psychology: Human Perception and Performance.

24.6.2023: How does increasing the relevance of distractors affect Simon and Flanker effects?

27.4.2023: A paper on the persistent effects of visual salience by Martin Constant and Heinrich Liesefeld was published in Journal of Experimental Psychology: General (https://doi.org/10.1037/xge0001420). Disconfirming earlier claims that effects of salience are short-lived and quickly overruled by top-down control, we demonstrate that even after 3s visual-working-memory performance is still affected by salience and that these effects cannot be overruled by various established top-down influences.
