In diesem Semester werden Sie in Kleingruppen jeweils ein eigenes Experiment planen, durchführen, auswerten und schließlich darüber berichten (in Form eines wissenschaftlichen Papers sowie über ein Poster).
Group 1 (Baess): This expra group will focus on the Simon effect as one kind of spatial compatibility effects. Based on one prominent theory (Hommel, B. (1993). The Relationship between Stimulus-Processing and Response Selection in the Simon Task - Evidence for a Temporal Overlap. Psychological Research-Psychologische Forschung, 55(4), 280-290. https://doi.org/Doi 10.1007/Bf00419688), several factors are suggested to modulate the size of the Simon effect. In a nutshell, any experimental factor that influences the presentation of the task-relevant and task-irrelevant stimulus information should accordingly modulate the size of the Simon effect. However, several data from our own work speak against this theory. We also recently replicated the whole experiments of this study and could not find the suggested effects. Therefore, in order to support our claim further that early stimulus-related factors are not modulating the size of the Simon effect, this expra group will conduct further research on early stimulus-related factors. Students are encouraged to think about further experimental manipulations in order to test our claim.
Group 2 (Baess): This expra group will focus on task sharing as a form of joint action using the Simon task. Based on the seminal study by Sebanz and colleagues (Sebanz, N., Knoblich, G., & Prinz, W. (2003). Representing others' actions: just like one's own? Cognition, 88, B11-B21.), it was suggested that partner's actions are processed like own action promoting the idea of action co-representation. Recent evidence has shown (Dolk, T., Hommel, B., Prinz, W., & Liepelt, R. (2013). The (Not So) Social Simon Effect: A Referential Coding Account. Journal of Experimental Psychology: Human Perception and Performance. https://doi.org/10.1037/a0031031) that the observed joint Simon effect might not be social in nature but rather is based on spatial coding of the environment. Thus, the observed joint Go/NoGo effects are differently explained by the two theoretical accounts. But what happens when three persons sitting next to one another share the Simon task? We recently gained evidence on the cognitive representations underlying the Simon task with three persons. In the expra, we want to expand on this research by investigating the role of the seating alignment and the spatial references further. Students are encouraged to think about experimental manipulations in order to investigate the joint Simon effect with three participants further.
Group 3 (Hackländer): This ExPra group will focus on olfactory associative memory. Specifically, we will be investigating how previously information associations interfere with the learning of new associations (and/or vice versa) and whether this differs between odors and other types of stimuli. This ExPra group will likely work with extra equipment (an olfactometer) and a large emphasis of the class will be on choosing the correct method and stimuli for testing our research question. Please make sure to sign up for the LearnWeb course. In preparation for this seminar, please read the following article: https://academic.oup.com/chemse/article/27/3/191/362372 *Note - there are NO GOOD articles on this topic up to this point, so keep this in mind while reading. The article is confusing, so do not get discouraged - we will use do things much simpler in our experiment.
Group 4 (Hackländer): In our research group we will be investigating the Event Horizon Model of memory. This theory is concerned with how a continuous stream of events at perception is seemingly converted to a series of discrete events in memory. We will develop an experiment to test a single hypothesis from this theory and assess the theory in light of the new evidence that we have found. Please make sure to sign up for the LearnWeb course. Please read the following two articles before class: https://journals.sagepub.com/doi/pdf/10.1177/0963721412451274 AND https://pmc.ncbi.nlm.nih.gov/articles/PMC5734104/pdf/nihms903261.pdf
Group 5 (Hackländer): In this ExPra group we will investigate collaborative memory. In other words, we will be interested in how learning information in a group, and discussing the information with that group, influences what is later remembered. Note - the study for this group will focus on a replication of previous research, and much of the methods are already set. Therefore, a greater proportion of the work for this group will be put into the data collection and data analyses than may be the case in other groups. Please make sure to sign up for the LearnWeb course. Before joining the group, please read the following article: https://www.sciencedirect.com/science/article/pii/S0749596X15000716
Group 6 (Bogenschütz): This ExPra group will investigate involuntarily retrieved odor-evoked autobiographical memoriy using a vigilance task. Together we will come up with experiments that will test whether the typical vigilance task can be applied for olfactory stimuli, or how odor-evoked involutarily retrieved AMs differ from other cue types. Please read the following article in preparation for the first class and sign up in the LearnWeb course. https://link.springer.com/content/pdf/10.3758/MC.36.5.920. Please note: the class will be tought by Luisa Bogenschütz until June 2nd. Afterwards, Ryan Hackländer will take over.
Group 7 (Fenske): In this ExPra group, we will investigate how the body position influences action control. We will most likely use the task switching paradigm while participants sit down or stand up.
Group 8 (Majer): In this ExPra, we will investigate why negotiation parties often make suboptimal compromises, although better agreement options would have been readily available. In addition, we seek to test an intervention that can help parties regain agency in the resolution of interdependent conflict situations to improve their long-term outcomes and create mutually satisfying solutions. Please make sure to sign up for the LearnWeb course.
Group 9 (Sandhagen): In this ExPra group we will investigate digital detox and well-being. Building on previous studies showing that less time spent on smartphone leads to more well-being (https://psycnet.apa.org/doiLanding?doi=10.1037%2Fxap0000430) we will explore whether short-term effects can be generated. Students are encouraged to think about experimental manipulations on time spent on smartphone vs alone vs in social action.
Group 10 (Pakai-Stecina): This research group will focus on attentional biases toward negative stimuli, such as threatening or disgusting images, and the mechanisms that inhibit these responses. Building on previous studies showing that negative distractors are difficult to suppress — and that shape-similar neutral distractors can capture attention in a similar way — we will explore how emotional and visual properties influence attentional control. Using methods like reaction time measurements, visual search tasks, and the Vernier task, we will design an experiment to investigate the factors that shape attentional bias and inhibition.
