Controlling attention through action: Observing actions primes action-related stimulus dimensions
No full textPrevious findings suggest that planning an action "backward-primes" perceptual dimension related to this action: planning a grasp facilitates the processing of visual size information, while planning a reach facilitates the processing of location information. Here we show that dimensional priming of perception through action occurs even in the absence of active action planning. Subjects watched video clips showing a grasping or reaching action before detecting size- or location-defined deviants in visual stimulus sequences. Size deviants were detected faster after seeing a grasp and location deviants were detected faster after seeing a reach. This supports the assumption that perceptual codes and action plans share a common representational medium, and that "attention to action" controls "attention to stimuli". (C) 2007 Elsevier Ltd.

Too complex for Simon? The influence of stimulus complexity on the Simon effect: A replication of Hommel(1994)
No full textThis study investigates the influence of stimulus complexity onto the Simon effect. The Simon effect describes the correspondence between irrelevant stimulus location and response location (e.g. Hommel (1993)), meaning a spatially compatible response to a stimulus is faster than a spatially incompatible response even if stimulus position is irrelevant.
According to Hommel (1993) the Simon effect is reduced when relevant and irrelevant stimulus features are temporally separated. This is called the temporal overlap account. Hommel(1993) demonstrated this effect across various experimental manipulations, including stimulus onset delay, stimulus eccentricity, and stimulus quality.
In a subsequent study, Hommel (1994) extended this line of research by focussing on the role of stimulus complexity. There are two conditions differing in complexity. The simple condition involves the discrimination of colour stimuli (blue vs. yellow) within a reference frame. The moderately complex condition requires participants to distinguish between shape stimuli, specifically a square and a rectangle, also within a reference frame. According to Hommel (1994), the Simon effect decreases as task complexity increases. To further investigate this claim, we introduce a third, more complex form condition, in which participants respond to a five-pointed star and a six-pointed star.
In contrary to Hommel (1994) we investigate not only the global Simon effect, but also the local Simon effect. Hommel (1994) and Umiltà and Liotti (1987) only mention „the Simon effect“, while we suggest that there are two different types of Simon effects as shown by Baess and Bermeitinger (2025). The global Simon effect arises when the spatial compatibility is determined by the absolute position of the stimulus on the screen (e.g., left vs. right side of a monitor). The local Simon effect emerges when spatial compatibility is defined within a localized frame of reference.
The Stimuli appear either on the left or right of the monitor and always either within the left or right frame. Umiltà and Liotti (1987) observed only a local Simon effect in their delay condition, which led to the emergence of the debate between the Attentional Zooming Theory and the Temporal Overlap Theory. The Attentional Zooming Theory postulates that attention can shift between spatial locations, affecting response times in the Simon effect, based on target congruence. Hommel (1994) adopted the experimental layout used by Umiltà and Liotti (1987), but manipulated the difficulty of the relevant feature (color vs. shape). The aim of our study is to replicate the results of Hommel (1994).
In line with Hommel (1994) we investigate the following hypothesis: We expect to find a global Simon effect in the colour condition and no global Simon effect in the form condition. Additionally, we expect to find no global Simon effect in the complex form condition.
