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.

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".
18.10.2023: A paper on whether Backward Crosstalk is due to facilitation or interference authored by Valentin Koob, Carlotta Sauerbier and Markus Janczyk together with Hannes Schröter (DIE Bonn/FernUni Hagen) and Rolf Ulrich (Tübingen) was accepted for publication in the Journal of Experimental Psychology: Human Perception and Performance.
1.10.2023: Jule Kinner joins our group as a new PhD student in Project A2 of the Research Unit "Modal and Amodal Cognition".
17.9.2023: A review paper on modal and amodal representations written by Barbara Kaup and Rolf Ulrich (Tübingen), Markus Janczyk and many other authors was accepted for publication in Psychological Research. The paper summarizes the topic and literature in the context of the Research Unit "Modal and Amodal Cognition" (FOR 2718).
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. Markus Janczyk is PI of the research unit’s projects A2 (“Amodal and modal representations in planning and control of human action“, with Prof. Dr. Volker Franz, University of Tübingen) and A4 ("Executive functions: Are amodal representations involved in proactive control?", with Dr. Carolin Dudschig and Prof. Dr. Hartmut Leuthold, University of Tübingen).
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? A paper addresssing this, written by Victor Mittelstädt and Ian Mackenzie (both Tübingen) and Valentin Koob and Markus Janczyk, was accepted for publication in the Journal of Experimental Psychology: Learning, Memory, and Cognition.
12.6.2023: A new paper by Markus Janczyk and Jeff Miller (U of Otago, Dunedin, NZL) was accepted for publication in Quarterly Journal of Experimental Psychology. According to this paper, action effects must be entirely predictable to yield a consistent advantage. Otherwise there seem to be large interindividual differences in what humans generalize from random variations of action effects.
20.5.2023: Heinrich Liesefeld and Markus Janczyk were granted the project "Validating (easy) measures to combine speed and accuracy" from the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG; 3 years, 100% postdoc position, travel and other funds).

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.
26.2.2023: What are advantages and disadvantages and how efficienct and accurate are different numerical methods to predict the RT distribution for diffusion models with time-dependent parameters?
