“…Other researchers have found that the details of the mental simulation exercise influence performance (e.g., Intons-Peterson & Roskos-Ewoldsen, 1989;Taylor et al, 1998). For example, Intons-Peterson and Roskos-Ewoldsen asked people to mentally travel specified routes and to press a button when they arrived at the destinationpoint.…”

Mental simulation inflates performance estimates for physical abilities

In five experiments, we examined how mental simulation of physical activities affected estimates of one's ability to perform the same activities. In Experiment 1, participants who simulated lifting a heavy object estimated that they could lift more weight than did participants who did not perform the simulation. In Experiment 2A, the frequency with which participants performed the simulation exercises was manipulated. In Experiments 2B and 2C, we manipulated the amount of weight that people simulated lifting in order to address potential alternative explanations of the inflation effect. In Experiment 3, mental simulations were manipulated within subjects. In all the experiments, the simulated events showed inflated estimates,as compared with nonsimulated events. These results were interpreted in the context of the misattribution-of-familiarity account of imagination inflation.

“…To see the basis for the dispute, suppose that subjects in an experiment take a specific amount of time to infer how long it will take them to walk 30 yards. Also suppose that when subjects are told they will be carrying a heavy backpack, it takes them longer to make their inference (Decety, Jeannerod, & Prablanc, 1989;Intons-Peterson & Roskos-Ewoldsen, 1989). An analog characterization of this backpack effect might be that people incorporate weight information into their imagery.…”

Physical Imagery: Kinematic versus Dynamic Models

Physical imagery occurs when people imagine one object causing a change to a second object. To make inferences through physical imagery, people must represent information that coordinates the interactions among the imagined objects. The current research contrasts two proposals for how this coordinating information is realized in physical imagery. In the traditional kinematic formulation, imagery transformations are coordinated by geometric information in analog spatial representations. In the dynamic formulation, transformations may also be regulated by analog representations of force and resistance. Four experiments support the dynamic formulation. They show, for example, that without making changes to the spatial properties of a problem, dynamic perceptual information (e.g., torque) and beliefs about physical properties (e.g., viscosity) affect the inferences that people draw through imagery. The studies suggest that physical imagery is not so much an analog of visual perception as it is an analog of physical action. A simple model that represents force as a rate helps explain why inferences can emerge through imagined actions even though people may not know the answer explicitly. It also explains how and when perception, beliefs, and learning can influence physical imagery. © 1999 Academic PressPeople solve spatial problems about shape, position, change of perspective, and navigation. People also solve physical problems about forces, resistances, and how one object causes changes to another. To a large extent, research on physical problem solving has emphasized people's beliefs and qualitative theories about physical behaviors, and research on spatial problem solving has emphasized people's analog representations of visual perception. As a consequence, research relevant to analog representation has generally investigated spatial and visual issues but not physical and haptic issues. This seems like an omission. Imagine, for example, running wall-towall in a breezy room and then imagine running wall-to-wall in waist deep water. Even though many of the spatial relations are identical, the effect of imagined resistance is introspectively compelling. Less introspectively, Sashank Varma was an invaluable source of ideas. I thank John Rieser and Howard Sandler for many productive conversations. I also thank several anonymous reviewers for their patience and detailed commentary.

“…This explanation has much in common with the knowledge-weighting model proposed by Intons-Peterson and her colleagues (Intons-Peterson & McDaniel, 1991;Intons-Peterson & Roskos-Ewoldsen, 1989), though they assume that the information retrieved from memory is in a canonical form. Relying on previous work (Hubbard et aI., 1989), we favor an explanation that has subjects retrieving memories of specific episodes from the past, more along the lines envisioned by Tulving (1983).…”
