“…Clearly, there is no evidence that such active control leads to error-free performance, as we had speculated in the Introduction. On the contrary, the magnitude of the errors found in the current study would appear to be on the higher end of the 2-15 min arc range previously estimated for perception alone [De Valois and De Valois 1991;Kerzel et al 2008;Tsui et al 2007]. Indeed, those estimates also include peripherally presented targets, and it is known that illusory displacement scales with eccentricity, increasing by 1-2 min arc per degree [Chung et al 2007;De Valois and De Valois 1991;Fu et al 2004].…”

“…When the sine-wave grating component of a Gabor patch is made to drift locally either to the left or right, the global position of the entire patch appears shifted in that direction, even though the physical position of the patch does not change [De Valois and De Valois 1991;Fu et al 2004]. Although the magnitude of this Gabor-based motion-induced illusory displacement is typically small -ranging between 2 and 15 min arc for centrally presented targets [De Valois and De Valois 1991;Kerzel et al 2008;Tsui et al 2007] -it is highly robust and has proven to be a very useful experimental tool for exploring the relationship between motion and position [Bressler and Whitney 2006;Chung et al 2007;Fu et al 2004;Kerzel and Gegenfurtner 2005;Rider et al 2009;Yamagishi et al 2001].…”

When the sine-wave grating of a Gabor patch drifts to the left or right, the perceived position of the entire object is shifted in the direction of local motion. In the current paper, we explored whether active control of the physical position of the patch can overcome such motion induced illusory displacement. We created a simple computer game and asked participants to continuously guide a Gabor patch along a randomly curving path. When the grating inside the Gabor patch was stationary, participants could perform this task without error. When the grating drifted to either left or right, we observed systematic errors consistent with previous reports of motion-induced illusory displacement. Specifically, when the grating drifted to the right, participants adjusted the global position of the patch to the left of the target line, and when it drifted to the left, errors were to the right of the line. The magnitude of the errors was consistent with previously reported perceptual judgements for centrally presented items, and scaled systematically with the speed of local drift. Importantly, we found no evidence that participants could adapt or compensate for illusory displacement given active control of the target. The current findings could have important implications for interface design, suggesting that local dynamic components of a display could affect perception and action within the more global application environment

“…Our first finding provides yet another example of the robust nature of this illusion. Although the size of the perceived shift during the passive task was relatively small, even for a centrally viewed target (De Valois and De Valois, 1991 ; Tsui et al, 2007 ; Kerzel et al, 2008 ), the influence of motion on position was extremely consistent, showing the same pattern in all 12 participants. In the absence of motion, there was a slight tendency to perceive the patch to the right of center, a tendency that was more apparent during the post-test phase.…”

“…However, if the patch drifts to the left or right within the aperture, the perceived position of the whole aperture is also shifted in the same direction. While the magnitude of this type of illusory position shift is typically quite small—ranging from 2 to 15 min arc for centrally presented targets (De Valois and De Valois, 1991 ; Tsui et al, 2007 ; Kerzel et al, 2008 )—it is highly robust and has proven particularly useful for exploring the level of visual processing that gives rise to MIPS (e.g., Fu et al, 2004 ; Arnold et al, 2007 ; Tsui et al, 2007 ; Mather and Pavan, 2009 ; Kosovicheva et al, 2012 ; Maus et al, 2013a , b ).…”

Local motion is known to produce strong illusory displacement in the perceived position of globally static objects. For example, if a dot-cloud or grating drifts to the left within a stationary aperture, the perceived position of the whole aperture will also be shifted to the left. Previously, we used a simple tracking task to demonstrate that active control over the global position of an object did not eliminate this form of illusion. Here, we used a new iPad task to directly compare the magnitude of illusory displacement under active and passive conditions. In the active condition, participants guided a drifting Gabor patch along a virtual slalom course by using the tilt control of an iPad. The task was to position the patch so that it entered each gate at the direct center, and we used the left/right deviations from that point as our dependent measure. In the passive condition, participants watched playback of standardized trajectories along the same course. We systematically varied deviation from midpoint at gate entry, and participants made 2AFC left/right judgments. We fitted cumulative normal functions to individual distributions and extracted the point of subjective equality (PSE) as our dependent measure. To our surprise, the magnitude of displacement was consistently larger under active than under passive conditions. Importantly, control conditions ruled out the possibility that such amplification results from lack of motor control or differences in global trajectories as performance estimates were equivalent in the two conditions in the absence of local motion. Our results suggest that the illusion penetrates multiple levels of the perception-action cycle, indicating that one important direction for the future of perceptual illusions may be to more fully explore their influence during active vision.

“…La captura atencional propone que estas interacciones pueden estar influenciadas por información biológicamente relevante, por características físicas de los estímulos o por las demandas del individuo. En cual-quiera de los casos, persiste el debate en torno a cuáles categorías de estímulos podrían ser más o menos fáciles de ignorar y si los movimientos oculares son una medida confiable que logre reflejar la captura atencional a los distractores (Hutton, 2008;Kerzel et al, 2008;McSorley & McCloy, 2009). En cuanto a esta última pregunta, se ha encontrado asociación entre los ERP y los movimientos oculares (Weaver et al, 2017), así como los movimientos oculares y la actividad hemodinámica cerebral en áreas asociadas con atención (Kimmig et al, 2001) que parecen reflejar patrones de actividad similares a los encontrados en los estudios de resonancia magnética funcional para los mecanismos de selección y supresión .…”

Conforme pasa la edad, se reportan varios cambios funcionales, anatómicos y conductuales en funciones cognitivas, como la atención y memoria de trabajo. Sin embargo, parece que la valencia emocional de los estímulos tiene un efecto en el procesamiento de información. El objetivo de la presente revisión es exponer la hipótesis de que los mecanismos atencionales de amplificación de información relevante y supresión de información irrelevante repercuten sobre la eficiencia en la memoria de trabajo, y proponer que estos mecanismos pudieran ser vulnerables al efecto de la valencia emocional de los estímulos. En esta revisión se expondrán los diferentes modelos de atención que permitan comprender el concepto de filtrado de la información para realizar tareas de competencia emocional. También, se discutirá el efecto de los distractores neutros y con valencia emocional sobre la eficiencia en la memoria de trabajo, contrastando la evidencia existente entre adultos jóvenes vs. adultos mayores. Finalmente, se plantea la hipótesis de los mecanismos atencionales y su impacto en la memoria de trabajo. Hasta donde es nuestro conocimiento, se desconoce cómo cambian estos mecanismos atencionales a lo largo de la vida adulta, cómo la valencia emocional impacta estos mecanismos y, potencialmente, la eficiencia de la memoria de trabajo. Los adultos mayores presentan una disminución en el mecanismo de supresión en comparación con los jóvenes, efecto no observado para el mecanismo de amplificación. Conforme la edad avanza, la valencia emocional impacta diferencialmente la captura atencional. Se presume que los cambios tanto en los mecanismos atencionales como en la valencia emocional tienen un potencial efecto sobre la memoria de trabajo.
