Are attentional momentum and representational momentum related

Journal of experimental psychology. Learning, memory, and cognition, 2009

Effects of a spatial cue on representational momentum were examined. If a cue was present during or after target motion and indicated the location at which the target would vanish or had vanished, forward displacement of that target decreased. The decrease in forward displacement was larger when cues were present after target motion than when cues were present during target motion. If a cue was present during target motion, high-relevant cues (that indicated the final location of the target) led to larger decreases in forward displacement than did low-relevant cues (that indicated only the horizontal coordinate of the final location of the target). If a cue was present after target motion, there was a trend for low-relevant cues to lead to larger decreases in forward displacement than did high-relevant cues. Possible explanations involving displacement of the cue or landmark attraction are considered. Implications for the relationship of attention and representational momentum, and ...

Memory for the final location of a moving target is often displaced in the direction of target motion, and this has been referred to as representational momentum. Characteristics of the target (e.g., velocity, size, direction, and identity), display (e.g., target format, retention interval, and response method), context (landmarks, expectations, and attribution of motion source), and observer (e.g., allocation of attention, eye movements, and psychopathology) that influence the direction and magnitude of displacement are reviewed. Specific conclusions regarding numerous variables that influence displacement (e.g., presence of landmarks or surrounding context), as well as broad-based conclusions regarding displacement in general (e.g., displacement does not reflect objective physical principles, may reflect aspects of naive physics, does not solely reflect eye movements, may involve some modular processing, and reflects high-level processes) are drawn. A possible computational theory of displacement is suggested in which displacement (1) helps bridge the gap between perception and action and (2) plays a critical part in localizing stimuli in the environment.

Cognition can exhibit biases consistent with future expectations, and some of these biases result in momentum-like effects and have been linked with the idea of an internalization of the effects of momentum. These momentum-like effects include representational momentum, operational momentum, and attentional momentum. Similarities and differences between these different momentum-like effects are considered. Hubbard's (2005) review of representational momentum is updated to include studies published since that review appeared, and the first full reviews of operational momentum and attentional momentum are provided. It is suggested that (1) many variables that influence one of these momentum-like effects have a similar influence on another momentum-like effect, (2) representational momentum, operational momentum, and attentional momentum reflect similar or overlapping mechanisms, and operational momentum and attentional momentum are special cases of representational momentum, and (...

The influence of a moving target on memory for the location of a briefly presented stationary object was examined. When the stationary object was aligned with the final portion of the moving target's trajectory, memory for the location of the stationary object was displaced forward (i.e., in the direction of motion of the moving target); the magnitude of forward displacement increased with increases in the velocity of the moving target, decreased with increases in the distance of the stationary object from the final location of the moving target, and increased and then decreased with increases in retention interval. It is suggested that forward displacement in memory for a stationary object aligned with the final portion of a moving target's trajectory reflects an influence of representational momentum of the moving target on memory for the location of the stationary object. Implications of the data for theories of representational momentum and motion induced mislocalization are discussed. Memory for the final position of a previously-viewed moving target is often displaced forward in the direction of target motion, and this has been referred to as representational momentum (e.g., Freyd & Finke, 1984; for review, see Hubbard, 2005). Although there have been numerous studies of the influence of a nearby stimulus on the representational momentum of a moving target (e.g.

Our visual experience of the world often takes the form of events in which objects and/or other aspects of a scene (e.g., the layout) move or change over time. Understanding how the brain processes such "dynamic events" poses a major challenge for theories of perception, memory, and cognition. This Special Issue presents a series of papers related to one topic in this arearepresentational momentum-the systematic tendency for observers to remember an event as extending beyond its actual ending point. For example, when observers view a moving target, that target is typically remembered as having travelled a little farther than it actually did. Representational momentum was first documented by Freyd and Finke (1984), and in their original paradigm, observers viewed three discrete presentations of a rotating rectangle. A brief retention interval (e.g., 250 ms) followed this inducing display and then a fourth, probe, rectangle was presented. Observers were asked to judge if the probe was at the same orientation as the third inducing rectangle. As long as the inducing display implied rotation in a consistent direction, observers were more likely to judge "same" when the probe was actually rotated a little further in the direction of motion. Using a different paradigm, Hubbard and Bharucha (1988) presented smooth continuous motion of a target travelling either vertically or horizontally. The target would vanish without warning and observers indicated the judged

Perception, 2014

Effects of the contrast of target luminance and background luminance, and of the absolute level of target luminance, on representational momentum for the remembered final location of a previously viewed moving target were examined. Targets were high in contrast or luminance, decreasing in contrast or luminance, increasing in contrast or luminance, or low in contrast or luminance; the background was black or white. Representational momentum for target location was larger if targets were high or increasing in contrast or luminance and smaller if targets were low or decreasing in contrast or luminance. Representational momentum for target location was larger if targets were presented on a white background than on a black background. Implications for theories of localization and for theories of representational momentum are discussed.

Cognition and behavior exhibit biases consistent with future expectations, and some of these biases result in momentum-like effects and have been linked with the idea of momentum. These momentum-like effects include representational momentum, operational momentum, attentional momentum, behavioral momentum, and psychological momentum. Effects of numerous variables involving characteristics of the target, display, context, or observer on each momentum-like effect are considered, and similarities of different momentum-like effects are considered. It is suggested that representational momentum, operational momentum, and attentional momentum reflect similar or overlapping mechanisms based on a perceptual timescale and extrapolation primarily across space, and that behavioral momentum and psychological momentum reflect similar or overlapping mechanisms based on a longer timescale and extrapolation primarily across time. It is further suggested that all 5 forms of momentum-like effect could reflect a more general extrapolation mechanism that anticipates the future action, behavior, or outcome of a given target, person, or process. A list of properties characterizing momentum-like effects is proposed, and constraints and issues relevant to future models of momentum-like effects are discussed.

The spatial memory for the last position occupied by a moving target is usually displaced forward in the direction of motion. Interpreted as a mental analogue of physical momentum, this phenomenon was coined representational momentum (RM). As momentum is given by the product of an object's velocity and mass, both these factors came to be under scrutiny in RM studies, the goal being to provide support for the internalization hypothesis. Although velocity was found to determine RM's magnitude, possible effects of mass were more elusive. Recently, an effect of target size on RM was reported, adding to previous findings that bigger targets were more mislocalized downward in the direction of gravity (via perceived heaviness and representational gravity; RG). The aim in the present research was to test that those outcomes reflect an internalization of momentum by excluding oculomotor factors. The results showed that an effect of target size, when it emerged, could be accounted for by a foveal bias such that bigger targets were more displaced toward gaze than were smaller ones. Specific contingencies between eye movements and target size seem to account for previous reports regarding the alleged effects of perceived mass on both RM and RG. This phenomenon seems furthermore to be modulated by the presence of other visual elements (fixation point) and the range of target velocities. These outcomes are taken as a rebuttal to the claim that cognitive analogues of mass or heaviness are responsible for previously reported effects of target size on both RM and RG.
