The present paper reflects on some of the hidden obstacles that have to be overcome in order to find unique psychophysiological relationships. These are, among others: (1) the different status of concepts which are defined in the two domains (ontological subjectivity in psychology and ontological objectivity in physiology); (2) the distinct hierarchical levels to which concepts from the two domains may belong; (3) ambiguity of concepts, because-due to limited measurement resolution or definitional shortcomings-they sometimes do not cover unique states or processes; (4) ignored context dependencies. Moreover, it is argued that due to the gigantic number of states and state changes, which are possible in a nervous system, it seems unlikely that neuroscience can provide exact causal explanations and predictions of behavior. Rather, as in statistical thermodynamics the transition from the microlevel of explanations to the macrolevel is only possible with probabilistic uncertainty.}, language = {en} } @article{MikelskisSeifertRoesler1999, author = {Mikelskis, Helmut and Seifert, Silke and Roesler, Frank}, title = {Optik lernen mit der Simulationssoftware phenOpt}, issn = {0025-5866}, year = {1999}, language = {de} } @article{MetznervonderMalsburgVasishthetal.2017, author = {Metzner, Paul and von der Malsburg, Titus Raban and Vasishth, Shravan and Roesler, Frank}, title = {The Importance of Reading Naturally: Evidence From Combined Recordings of Eye Movements and Electric Brain Potentials}, series = {Cognitive science : a multidisciplinary journal of anthropology, artificial intelligence, education, linguistics, neuroscience, philosophy, psychology ; journal of the Cognitive Science Society}, volume = {41}, journal = {Cognitive science : a multidisciplinary journal of anthropology, artificial intelligence, education, linguistics, neuroscience, philosophy, psychology ; journal of the Cognitive Science Society}, publisher = {Wiley}, address = {Hoboken}, issn = {0364-0213}, doi = {10.1111/cogs.12384}, pages = {1232 -- 1263}, year = {2017}, language = {en} } @article{KhaderPachurMeieretal.2011, author = {Khader, Patrick H. and Pachur, Thorsten and Meier, Stefanie and Bien, Siegfried and Jost, Kerstin and Roesler, Frank}, title = {Memory-based decision-making with heuristics evidence for a controlled activation of memory representations}, series = {Journal of cognitive neuroscience}, volume = {23}, journal = {Journal of cognitive neuroscience}, number = {11}, publisher = {MIT Press}, address = {Cambridge}, issn = {0898-929X}, pages = {3540 -- 3554}, year = {2011}, abstract = {Many of our daily decisions are memory based, that is, the attribute information about the decision alternatives has to be recalled. Behavioral studies suggest that for such decisions we often use simple strategies (heuristics) that rely on controlled and limited information search. It is assumed that these heuristics simplify decision-making by activating long-term memory representations of only those attributes that are necessary for the decision. However, from behavioral studies alone, it is unclear whether using heuristics is indeed associated with limited memory search. The present study tested this assumption by monitoring the activation of specific long-term-memory representations with fMRI while participants made memory-based decisions using the "take-the-best" heuristic. For different decision trials, different numbers and types of information had to be retrieved and processed. The attributes consisted of visual information known to be represented in different parts of the posterior cortex. We found that the amount of information required for a decision was mirrored by a parametric activation of the dorsolateral PFC. Such a parametric pattern was also observed in all posterior areas, suggesting that activation was not limited to those attributes required for a decision. However, the posterior increases were systematically modulated by the relative importance of the information for making a decision. These findings suggest that memory-based decision-making is mediated by the dorsolateral PFC, which selectively controls posterior storage areas. In addition, the systematic modulations of the posterior activations indicate a selective boosting of activation of decision-relevant attributes.}, language = {en} } @article{FiehlerBannertBischoffetal.2011, author = {Fiehler, Katja and Bannert, Michael M. and Bischoff, Matthias and Blecker, Carlo and Stark, Rudolf and Vaitl, Dieter and Franz, Volker H. and Roesler, Frank}, title = {Working memory maintenance of grasp-target information in the human posterior parietal cortex}, series = {NeuroImage : a journal of brain function}, volume = {54}, journal = {NeuroImage : a journal of brain function}, number = {3}, publisher = {Elsevier}, address = {San Diego}, issn = {1053-8119}, doi = {10.1016/j.neuroimage.2010.09.080}, pages = {2401 -- 2411}, year = {2011}, abstract = {Event-related functional magnetic resonance imaging was applied to identify cortical areas involved in maintaining target information in working memory used for an upcoming grasping action. Participants had to grasp with their thumb and index finger of the dominant right hand three-dimensional objects of different size and orientation. Reaching-to-grasp movements were performed without visual feedback either immediately after object presentation or after a variable delay of 2-12 s. The right inferior parietal cortex demonstrated sustained neural activity throughout the delay, which overlapped with activity observed during encoding of the grasp target. Immediate and delayed grasping activated similar motor-related brain areas and showed no differential activity. The results suggest that the right inferior parietal cortex plays an important functional role in working memory maintenance of grasp-related information. Moreover, our findings confirm the assumption that brain areas engaged in maintaining information are also involved in encoding the same information, and thus extend previous findings on working memory function of the posterior parietal cortex in saccadic behavior to reach-to-grasp movements.}, language = {en} }
