Beisert, Miriam; Massen, Cristina; Prinz, Wolfgang – Journal of Experimental Psychology: Human Perception and Performance, 2010
In tool use, a transformation rule defines the relation between an operating movement and its distal effect. This rule is determined by the tool structure and requires no explicit definition. The present study investigates how humans represent and apply compatible and incompatible transformation rules in tool use. In Experiment 1, participants had…

Thaler, Lore; Todd, James T. – Journal of Experimental Psychology: Human Perception and Performance, 2010
Visual information can specify spatial layout with respect to the observer (egocentric) or with respect to an external frame of reference (allocentric). People can use both of these types of visual spatial information to guide their hands. The question arises if movements based on egocentric and movements based on allocentric visual information…

Lim, Stephen Wee Hun; Chua, Fook K. – Journal of Experimental Psychology: Human Perception and Performance, 2008
When a target is enclosed by a 4-dot mask that persists after the target disappears, target identification is worse than it is when the mask terminates with the target. This masking effect is attributed to object substitution masking (OSM). Previewing the mask, however, attenuates OSM. This study investigated specific conditions under which mask…

Liepelt, Roman; Cramon, D. Yves Von; Brass, Marcel – Journal of Experimental Psychology: Human Perception and Performance, 2008
Converging evidence has shown that action observation and execution are tightly linked. The observation of an action directly activates an equivalent internal motor representation in the observer (direct matching). However, whether direct matching is primarily driven by basic perceptual features of the observed movement or is influenced by more…

Hsieh, P. -J.; Tse, P. U. – Journal of Experimental Psychology: Human Perception and Performance, 2007
After prolonged viewing of a slowly drifting or rotating pattern under strict fixation, the pattern appears to slow down and then momentarily stop. The authors show that grouping can slow down the process of "motion fading," suggesting that cortical configural form analysis interacts with the computation of motion signals during motion fading. The…

Stanley, James; Gowen, Emma; Miall, R. Chris – Journal of Experimental Psychology: Human Perception and Performance, 2007
Human movement performance is subject to interference if the performer simultaneously observes an incongruent action. It has been proposed that this phenomenon is due to motor contagion during simultaneous movement performance-observation, with coactivation of shared action performance and action observation circuitry in the premotor cortex. The…

Bosbach, Simone; Prinz, Wolfgang; Kerzel, Dirk – Journal of Experimental Psychology: Human Perception and Performance, 2004
To clarify whether motion information per se has a separable influence on action control, the authors investigated whether irrelevant direction of motion of stimuli whose overall position was constant over time would affect manual left-right responses (i.e., reveal a motion-based Simon effect). In Experiments 1 and 2, significant Simon effects…

Kallie, Christopher S.; Schrater, Paul R.; Legge, Gordon E. – Journal of Experimental Psychology: Human Perception and Performance, 2007
Walking without vision results in veering, an inability to maintain a straight path that has important consequences for blind pedestrians. In this study, the authors addressed whether the source of veering in the absence of visual and auditory feedback is better attributed to errors in perceptual encoding or undetected motor error. Three…

Mitra, Suvobrata; Turvey, M. T. – Journal of Experimental Psychology: Human Perception and Performance, 2004
In 3 experiments, the authors investigated changes in hand orientation during a 3-D reaching task that imposed specific position and orientation requirements on the hand's initial and final postures. Instantaneous hand orientation was described using 3-element rotation vectors representing current orientation as a rotation from a fixed reference…

Morein-Zamir, Sharon; Chua, Romeo; Franks, Ian; Nagelkerke, Paul; Kingstone, Alan – Journal of Experimental Psychology: Human Perception and Performance, 2007
Using a continuous tracking task, the authors examined whether stopping is resistant to expectancies as well as whether it is a representative measure of response control. Participants controlled the speed of a moving marker by continuously adjusting their response force. Participants stopped their ongoing tracking in response to auditory signals…

Pinto, Yair; Olivers, Christian N. L.; Theeuwes, Jan – Journal of Experimental Psychology: Human Perception and Performance, 2006
Intuitively, dynamic visual stimuli, such as moving objects or flashing lights, attract attention. Visual search tasks have revealed that dynamic targets among static distractors can indeed efficiently guide attention. The present study shows that the reverse case, a static target among dynamic distractors, allows for relatively efficient…

Creem-Regehr, Sarah H.; Gooch, Amy A.; Sahm, Cynthia S.; Thompson, William B. – Journal of Experimental Psychology: Human Perception and Performance, 2004
In 4 experiments, the authors varied the extent and nature of participant movement in a virtual environment to examine the influence of action on estimates of geographical slant. Previous studies showed that people consciously overestimate hill slant but can still accurately guide an action toward the hill (D. R. Proffitt, M. Bhalla, R.…

Stankiewicz, Brian J.; Legge, Gordon E.; Mansfield, J. Stephen; Schlicht, Erik J. – Journal of Experimental Psychology: Human Perception and Performance, 2006
The authors describe 3 human spatial navigation experiments that investigate how limitations of perception, memory, uncertainty, and decision strategy affect human spatial navigation performance. To better understand the effect of these variables on human navigation performance, the authors developed an ideal-navigator model for indoor navigation…

Soto-Faraco, Salvador; Spence, Charles; Kingstone, Alan – Journal of Experimental Psychology: Human Perception and Performance, 2004
This study investigated multisensory interactions in the perception of auditory and visual motion. When auditory and visual apparent motion streams are presented concurrently in opposite directions, participants often fail to discriminate the direction of motion of the auditory stream, whereas perception of the visual stream is unaffected by the…

Gilroy, Lee A.; Hock, Howard S. – Journal of Experimental Psychology: Human Perception and Performance, 2004
The perception of 2nd-order, texture-contrast-defined motion was studied for apparent-motion stimuli composed of a pair of spatially displaced, simultaneously visible checkerboards. It was found that background-relative, counter-changing contrast provided the informational basis for the perception of 2nd-order apparent motion; motion began where…
