PAPER From outcome prediction to action selection: developmental change in the role of action–effect bindings
2015Co-Authors: Stephan A. Verschoor, Szilvia Biro, Bernhard HommelAbstract:Ideomotor Theory considers bidirectional action–effect associations to be the fundamental building blocks for intentional action. The present study employed a novel pupillometric and oculomotor paradigm to study developmental changes in the role of action-effects in the acquisition of voluntary action. Our findings suggest that both 7- and 12-month-olds (and adults) can use acquired action–effect bindings to predict action outcomes but only 12-month-olds (and adults) showed evidence for employing action-effects to select actions. This dissociation supports the idea that infants acquire action–effect knowledge before they have developed the cognitive machinery necessary to make use of that knowledge to perform intentional actions

RUNNING HEAD: AFFECTIVE ACTION CONSEQUENCES Directive and Incentive Functions of Affective Action Consequences:
2014Co-Authors: Andreas B. Eder, Bernhard Hommel, Klaus Rothermund, Jan De Houwer, Address Andreas, B. EderAbstract:Five experiments examined whether affective consequences become associated with the responses producing them, and whether anticipations of positive and negative action outcomes influence action control differently. In a learning phase, one response produced pleasant and another response unpleasant visual effects. In a subsequent test phase, the same actions were carried out in response to a neutral feature of affective stimuli. Results showed that responses were faster when the irrelevant valence of the response cue matched the valence of the response outcome, but only when the responses still produced outcomes. These results suggest that affective action consequences have a directive function in that they facilitate the selection of the associated response over other responses, even when the response outcome is unpleasant (Experiment 4A). Results of another experiment showed that affective action consequences can also have an incentive function in that responses with pleasant outcomes are generally facilitated relative to responses with unpleasant outcomes. However, this motivational effect was seen only in a free-choice test (Experiment 5). The results suggest that behavioral impulses induced by Ideomotor processes are constrained by the motivational evaluation of the anticipated action outcome. A model that integrates motivational factors into Ideomotor Theory is presented

The Functional and Neural Mechanism of Action Preparation: Roles of EBA and FFA in Voluntary Action Control
MIT Press - Journals, 2011Co-Authors: Simone Kühn, André W. Keizer, Serge A. R. B. Rombouts, Bernhard HommelAbstract:Abstract Ideomotor Theory claims that actions are cognitively represented and accessed via representations of the sensory effects they evoke. Previous studies provide support for this claim by showing that the presentation of action effects primes activation in corresponding motor structures. However, whether people actually use action-effect representations to control their motor behavior is not yet clear. In our fMRI study, we had participants prepare for manual or facial actions on a trial-by-trial basis, and hypothesized that preparation would be mediated by the cortical areas that code for the perceptual effects of these actions. Preparing for manual action induced higher activation of hand-related areas of motor cortex (demonstrating actual preparation) and of the extrastriate body area, which is known to mediate the perception of body parts. In contrast, preparing for facial action induced higher activation of face-related motor areas and of the fusiform face area, known to mediate face perception. These observations provide further support for the Ideomotor Theory and suggest that visual imagery might play a role in voluntary action control.

Where Do Action Goals Come from? Evidence for Spontaneous Action–Effect Binding in Infants
Frontiers in psychology, 2010Co-Authors: Stephan Verschoor, Maaike Weidema, Szilvia Biro, Bernhard HommelAbstract:One of the great questions in psychology concerns how we develop to become intentional agents. Ideomotor Theory suggests that intentional actions depend on, and emerge from the automatic acquisition of bidirectional action–effect associations: perceiving an action–effect sequence creates an integrated representation that can be employed for action control in the opposite order, selecting an action by anticipating its effect. We provide first evidence for the spontaneous acquisition of bidirectional action–effect associations in 9- 12-, and 18-month-olds, suggesting that the mechanism underlying action–effect integration is in place at the latest around 9 months of age.

Action-Effect Bindings and Ideomotor Learning in Intention- and Stimulus-Based Actions
Frontiers in Psychology, 2012Co-Authors: Arvid Herwig, Florian WaszakAbstract:According to Ideomotor Theory, action-effect associations are crucial for voluntary action control. Recently, a number of studies started to investigate the conditions that mediate the acquisition and application of action-effect associations by comparing actions carried out in response to exogenous stimuli (stimulus-based) with actions selected endogenously (intention-based). There is evidence that the acquisition and/or application of action-effect associations is boosted when acting in an intention-based action mode. For instance, bidirectional action-effect associations were diagnosed in a forced choice test phase if participants previously experienced action-effect couplings in an intention-based but not in a stimulus-based action mode. The present study aims at investigating effects of the action mode on action-effect associations in more detail. In a series of experiments, we compared the strength and durability of short-term action-effect associations (binding) immediately following intention-as well as stimulus-based actions. Moreover, long-term action-effect associations (learning) were assessed in a subsequent test phase. Our results show short-term action-effect associations of equal strength and durability for both action modes. However, replicating previous results, long-term associations were observed only following intention-based actions. These findings indicate that the effect of the action mode on long-term associations cannot merely be a result of accumulated short-term action-effect bindings. Instead, only those episodic bindings are selectively perpetuated and retrieved that integrate action-relevant aspects of the processing event, i.e., in case of intention-based actions, the link between action and ensuing effect.

The internal anticipation of sensory action effects: when action induces FFA and PPA activity
Frontiers in Human Neuroscience, 2010Co-Authors: Simone Kühn, Ruth Seurinck, Wim Fias, Florian WaszakAbstract:Voluntary action - in particular the ability to produce desired effects in the environment - is fundamental to human existence. According to Ideomotor Theory we can achieve goals in the environment by means of anticipating their outcomes. We aimed at providing neurophysiological evidence for the assumption that performing actions calls for the activation of brain areas associated with the sensory effects usually evoked by the actions. We conducted an fMRI study in which right and left button presses lead to the presentation of face and house pictures. We compared a baseline phase with the same phase after participants experienced the association between button presses and pictures. We found an increase in the parahippocampal place area (PPA) for the response that has been associated with house pictures and fusiform face area (FFA) for the response that has been coupled with face pictures. This observation constitutes support for Ideomotor Theory.

The impact of subliminal effect images in voluntary vs. stimulus-driven actions
Elsevier, 2016Co-Authors: Le Bars Solène, Hsu Yi-fang, Waszak FlorianAbstract:International audienceAccording to the Ideomotor Theory, actions are represented in terms of their sensory effects. In the current study we tested whether subliminal effect images influence action control (1) at early and/or late preparatory stages of (2) voluntary actions or stimulus-driven actions (3) with or without Stimulus-Response (S-R) compatibility. In Experiment 1, participants were presented at random with 50% of S-R compatible stimulus-driven action trials and 50% of voluntary action trials. The actions' effects (i.e. up-or down-pointing arrows) were presented subliminally before each action (i.e. a keypress). In voluntary actions, participants selected more often the action congruent with the prime when it was presented at long intervals before the action. Moreover they responded faster in prime-congruent than in prime-incongruent trials when primes were presented at short intervals before the action. In Experiment 2, participants were only presented with stimulus-driven action trials, with or without S-R compatibility. In stimulus-driven action trials with S-R compatibility (e.g., left-pointing arrow signaling a left keypress), subliminal action-effects did not generate any significant effect on RTs or error rates. On the other hand, in stimulus-driven action trials without S-R compatibility (e.g., letter ''H" signaling a left keypress), participants were significantly faster in prime-congruent trials when primes were presented at the shortest time interval before the action. These results suggest that subliminal effect images facilitate voluntary action preparation on an early and a late level. Stimulus-driven action preparation is influenced on a late level only, and only if there is no compatibility between the stimulus and the motor response, that is when the response is not automatically triggered by the common properties existing between the stimulus and the required action

Representational precision in visual cortex reveals outcome encoding and reward modulation during action preparation
2017Co-Authors: Van Steenbergen H., Kuhn S., De Wit S., Wiers R.w., Warren C.m., Hommel B.Abstract:According to Ideomotor Theory, goal-directed action involves the active perceptual anticipation of actions and their associated effects. We used multivariate analysis of fMRI data to test if preparation of an action promotes precision in the perceptual representation of the action. In addition, we tested how reward magnitude modulates this effect. Finally, we examined how expectation and uncertainty impact neural precision in the motor cortex. In line with our predictions, preparation of a hand or face action increased the precision of neural activation patterns in the extrastriate body area (EBA) and fusiform face area (FFA), respectively. The size of this effect of anticipation predicted individuals' efficiency at performing the prepared action. In addition, increasing reward magnitude increased the precision of perceptual representations in both EBA and FFA although this effect was limited to the group of participants that learned to associate face actions with high reward. Surprisingly, examination of representations in the hand motor cortex and face motor cortex yielded effects in the opposite direction. Our findings demonstrate that the precision of representations in visual and motor areas provides an important neural signature of the sensorimotor representations involved in goal-directed action

Limits of Ideomotor action-outcome acquisition
'Elsevier BV', 2015Co-Authors: Watson P., Van Steenbergen H., De Wit S., Wiers R.w., Hommel B.Abstract:Ideomotor Theory proposes that goal-directed action emerges from the implicit, incidental acquisition of bi-directional associations between actions and their outcomes. In line with this idea, a simple two-stage priming paradigm has provided evidence that presentation of outcomes primes previously associated actions. In the current study we compare the standard priming paradigm with two actions and two unique outcomes (Experiment 1) with two more complex, but otherwise identical versions (Experiment 2: two vs. four actions with four outcomes). Our results show stronger evidence of action-outcome learning in the simple compared to the more complex versions. We suggest that, when using the classic two-stage paradigm, action-outcome acquisition is limited to just a few action-outcome associations that can be concurrently learned—at least if learning is not supported by discriminative stimuli and outcomes are not salient or motivationally relevant
