“…More precisely, in agreement with previous experimental studies, the IPS/SPL simulated similar neural processing times to perform both counterclockwise and clockwise rotation [20]. More importantly, and also consistent with the literature, the neural processing time of the IPS/SPL to perform the mental rotation increased linearly with the magnitude of the rotation angle regardless of the rotation direction [20].…”

It has been suggested that the human mirror neuron system (MNS) plays a critical role in action observation and imitation. However, the transformation of perspective between the observed (allocentric) and the imitated (egocentric) actions has received little attention. We expand a previously proposed biologically plausible MNS model by incorporating general spatial transformation capabilities that are assumed to be encoded by the intraparietal sulcus (IPS) and the superior parietal lobule (SPL) as well as investigating their interactions with the inferior frontal gyrus and the inferior parietal lobule. The results reveal that the IPS/SPL could process the frame of reference and the viewpoint transformations, and provide invariant visual representations for the temporo-parieto-frontal circuit. This allows the imitator to imitate the action performed by a demonstrator under various perspectives while replicating results from the literatures. Our results confirm and extend the importance of perspective transformation processing during action observation and imitation.

“…In light of previous studies focusing on mental rotation, the relationship between the rotation angle and the response time was examined [20]. Here, the response time was defined as the required time for the IPS/SPL to successfully transform the observed action including rotation, translation, and scaling.…”

Feature binding is a core concept in many research fields, including the study of working memory (WM). Over the past decade, it has been debated whether keeping the feature binding in visual WM consumes more visual attention than the constituent single features. Previous studies have only explored the contribution of domain-general attention or space-based attention in the binding process; no study so far has explored the role of object-based attention in retaining binding in visual WM. We hypothesized that object-based attention underlay the mechanism of rehearsing feature binding in visual WM. Therefore, during the maintenance phase of a visual WM task, we inserted a secondary mental rotation (Experiments 1-3), transparent motion (Experiment 4), or an object-based feature report task (Experiment 5) to consume the object-based attention available for binding. In line with the prediction of the object-based attention hypothesis, Experiments 1-5 revealed a more significant impairment for binding than for constituent single features. However, this selective binding impairment was not observed when inserting a space-based visual search task (Experiment 6). We conclude that object-based attention underlies the rehearsal of binding representation in visual WM.

“…Although both tasks are usually treated separately in the literature, the majority of OBT- and AIS-studies have in common that they use laterality decisions, i.e., observers have to make left or right judgments about absolute or relative object locations from the figure’s point of view. Recently, the number of behavioral and neurophysiological studies on visual perspective taking has been growing (Blanke et al, 2005; Creem-Regehr et al, 2007; Kessler and Thomson, 2010; Yu and Zacks, 2010; Dalecki et al, 2012 and others reviewed here). Note, that studies on viewpoint-dependent object (Tarr and Bülthoff, 1998) or scene recognition (Diwadkar and McNamara, 1997) are not considered, as their focus is on memory-based identification processes, and not on perspective taking.…”

Perspective taking plays an important role in different areas of psychological and neuroscientific research. Visual perspective taking is an especially prominent approach generally using one of two experimental tasks: in the own-body-transformation task observers are asked to judge the laterality of a salient feature of a human figure (e.g., is the glove on the left or right hand?) from the figure’s perspective. In the avatar-in-scene task they decide about the laterality of objects in a scene (e.g., is the flower on the left or right?) from the avatar’s point of view. Increases in latencies and/or errors are interpreted as originating from additional cognitive processes predominately described as observer-based perspective transformations. A closer look reveals that such an account is disputable on grounds related to the use of laterality judgments. Other transformation accounts, i.e., object or array transformations, as well as non-transformational accounts, i.e., extra processing due to spatial conflicts, have not been adequately considered, tested, or ruled out by existing research. Our review examines visual perspective tasks in detail, identifies problems and makes recommendations for future research.
