One specific question we address in this paper is what makes cross-representational interplay possible? We offer two distinct theoretical scenarios: according to the first scenario, co-activated knowledge representations interact with the help of an interface established between them via congruent activation in a mediating third-party general cognitive mechanism, e.g., attention. According to the second scenario, co-activated knowledge representations interact due to an overlap between their features, for example when they share a magnitude component. First, we make a case for cross representational interplay based on grounded and situated theories of cognition. Second, we discuss interface-based interactions between distinct (i.e., non-overlapping) knowledge representations. Third, we discuss how co-activated representations may share their architecture via partial overlap. Finally, we outline constraints regarding the flexibility of these proposed mechanisms.}, language = {en} } @misc{MyachykovFischer2019, author = {Myachykov, Andriy and Fischer, Martin H.}, title = {A hierarchical view of abstractness}, series = {Physics of life reviews}, volume = {29}, journal = {Physics of life reviews}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1571-0645}, doi = {10.1016/j.plrev.2019.04.005}, pages = {161 -- 163}, year = {2019}, language = {en} } @article{MyachykovEllisCangelosietal.2013, author = {Myachykov, Andriy and Ellis, Rob and Cangelosi, Angelo and Fischer, Martin H.}, title = {Visual and linguistic cues to graspable objects}, series = {Experimental brain research}, volume = {229}, journal = {Experimental brain research}, number = {4}, publisher = {Springer}, address = {New York}, issn = {0014-4819}, doi = {10.1007/s00221-013-3616-z}, pages = {545 -- 559}, year = {2013}, abstract = {Two experiments investigated (1) how activation of manual affordances is triggered by visual and linguistic cues to manipulable objects and (2) whether graspable object parts play a special role in this process. Participants pressed a key to categorize manipulable target objects copresented with manipulable distractor objects on a computer screen. Three factors were varied in Experiment 1: (1) the target's and (2) the distractor's handles' orientation congruency with the lateral manual response and (3) the Visual Focus on one of the objects. In Experiment 2, a linguistic cue factor was added to these three factors-participants heard the name of one of the two objects prior to the target display onset. Analysis of participants' motor and oculomotor behaviour confirmed that perceptual and linguistic cues potentiated activation of grasp affordances. Both target- and distractor-related affordance effects were modulated by the presence of visual and linguistic cues. However, a differential visual attention mechanism subserved activation of compatibility effects associated with target and distractor objects. We also registered an independent implicit attention attraction effect from objects' handles, suggesting that graspable parts automatically attract attention during object viewing. This effect was further amplified by visual but not linguistic cues, thus providing initial evidence for a recent hypothesis about differential roles of visual and linguistic information in potentiating stable and variable affordances (Borghi in Language and action in cognitive neuroscience.

Tropic representational features reflect constraints of the physical world on the agent's ability to form, reactivate, and enrich embodied (i.e., resulting from the agent's bodily constraints) conceptual representations embedded in situated contexts. The proposed hierarchy entails that representations can, in principle, have tropic features without necessarily having situated and/or embodied features. On the other hand, representations that are situated and/or embodied are likely to be simultaneously tropic. Hence, although we propose tropism as the most general term, the hierarchical relationship between embodiment and situatedness is more on a par, such that the dominance of one component over the other relies on the distinction between offline storage versus online generation as well as on representation-specific properties.}, language = {en} } @article{MyachykovCangelosiEllisetal.2015, author = {Myachykov, Andriy and Cangelosi, Angelo and Ellis, Rob and Fischer, Martin H.}, title = {The oculomotor resonance effect in spatial-numerical mapping}, series = {Acta psychologica : international journal of psychonomics}, volume = {161}, journal = {Acta psychologica : international journal of psychonomics}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0001-6918}, doi = {10.1016/j.actpsy.2015.09.006}, pages = {162 -- 169}, year = {2015}, abstract = {We investigated automatic Spatial-Numerical Association of Response Codes (SNARC) effect in auditory number processing. Two experiments continually measured spatial characteristics of ocular drift at central fixation during and after auditory number presentation. Consistent with the notion of a spatially oriented mental number line, we found spontaneous magnitude-dependent gaze adjustments, both with and without a concurrent saccadic task. This fixation adjustment (1) had a small-number/left-lateralized bias and (2) it was biphasic as it emerged for a short time around the point of lexical access and it received later robust representation around following number onset. This pattern suggests a two-step mechanism of sensorimotor mapping between numbers and space a first-pass bottom-up activation followed by a top-down and more robust horizontal SNARC Our results inform theories of number processing as well as simulation-based approaches to cognition by identifying the characteristics of an oculomotor resonance phenomenon.
