“…Instead of imagining themselves in the position of the pictured body, observers would solve same-different tasks by using an "object-based spatial transformation" or object mental rotation to align both the reference and comparison postures. However, although viewer mental rotation is generally at an advantage over object mental rotation (Wraga, Creem, & Proffitt, 1999), this is not the case when imagining physically impossible self-rotations such as a roll motion in the coronal plane (M. Carpenter & Proffitt, 2001;Creem, Wraga, & Proffitt, 2001;Van Lier, 2003), corresponding to the picture-plane rotations investigated by Zacks and colleagues (2001Zacks and colleagues ( , 2002Zacks and colleagues ( , 2003. The latter findings certainly run counter the hypotheses of Zacks and colleagues.…”

The cognitive advantage of imagined spatial transformations of the human body over that of more unfamiliar objects (e.g., Shepard-Metzler [S-M] cubes) is an issue for validating motor theories of visual perception. In 6 experiments, the authors show that providing S-M cubes with body characteristics (e.g., by adding a head to S-M cubes to evoke a posture) facilitates the mapping of the cognitive coordinate system of one's body onto the abstract shape. In turn, this spatial embodiment improves object shape matching. Thanks to the increased cohesiveness of human posture in people's body schema, imagined transformations of the body operate in a less piecemeal fashion as compared with objects (S-M cubes or swing-arm desk lamps) under a similar spatial configuration, provided that the pose can be embodied. If the pose cannot be emulated (covert imitation) by the sensorimotor system, the facilitation due to motoric embodiment will also be disrupted.

“…However, when they were asked the location of a particular item or asked to construct a copy of the transformed array, array rotations were easier. Array rotations also have been found to be easier when the stimuli were simple symmetric line drawings (van Lier, 2003).…”

Transformations of visuospatial mental imagesHere are some simple instructions: "Close your eyes.Imagine you are standing in front of a pedestal facing a bust of William James. Imagine now that you have walked around the pedestal and are now viewing the bust from the side. Now, imagine that a motor is turning the bust, allowing you to view it from a range of angles. Finally, imagine that you reach out, pick up the bust, and turn it upside-down to look at the bottom."Most people report that they can follow such instructions, and doing so often results in phenomenal experiences that are vivid and faithful to reality-though the degree that this is the case varies among individuals (Isaac and Marks, 1994). The experiences evoked by instructions such as these are transformations of visuospatial images. They may not require explicit intentions to produce: Humans and other animals appear to construct and transform visuospatial representations to solve a range of everyday reasoning problems, including navigation, the making and using of tools, and construction. But what is the computational and neurophysiological nature of the representations involved? How are those representations transformed during explicit and implicit visuospatial imagery?There is now a body of theory and evidence speaking to each of these questions. The goals of this article are, first, to introduce a framework for thinking about visuospatial image transformations, and, second, to interpret the available data within that framework to provide current best answers to both questions. To do so, we first provide an overview of the phenomena constituting visuospatial imagery and then describe a framework for relating image transformations to the representations on which they operate. The rest of the article characterizes different types of image transformations and the relations among them. The article's major empirical claim is that two sorts of visuospatial transformations can be dissociated: transformations in which the representations of individual objects are updated relative to other spatial representations and transformations in which one's personal perspective is updated. These visuospatial transformations are characterized by different patterns of behavioral performance, different neural correlates, and different psychometric properties. 96Authors' Note: We would like to thank Ty Fagan for his assistance with the meta-analysis.

“…Phenomenologically, the task-frame in this condition remained static 6 The interpretation of a linear relationship between response time and displacement angle as reflecting physical rotations has been criticised on grounds that many mental imagery tasks are found to be cognitively penetrable [205], and that mental rotation is a visually complex task ( [25; 98]; but see [233]). Regardless of the actual matching process underlying the mental process however, mental rotation for static displays is thought to be based on object orientation, because the viewpoint of the observer always remains the same [266].…”
