Full-text available
The influence of delayed auditory feedback on action evaluation and execution of real-life action-induced sounds apart from language and music is still poorly understood. Here, we examined how a temporal delay impacted the behavioral evaluation and neural representation of hurdling and tap-dancing actions in a functional magnetic resonance imaging...
Article
Full-text available
Most human actions produce concomitant sounds. Action sounds can be either part of the action goal (GAS, goal-related action sounds), as for instance in tap dancing, or a mere by-product of the action (BAS, by-product action sounds), as for instance in hurdling. It is currently unclear whether these two types of action sounds-incidental or intentio...

While prediction errors have been established to instigate learning through model adaptation , recent studies have stressed the role of model-compliant events in predictive processing. Specifically, so-called checkpoints have been suggested to be sampled for model evaluation , particularly in uncertain contexts. Using electroencephalography (EEG),...

Full-text available
While prediction errors (PE) have been established to drive learning through adaptation of internal models, the role of model-compliant events in predictive processing is less clear. Checkpoints (CP) were recently introduced as points in time where expected sensory input resolved ambiguity regarding the validity of the internal model. Conceivably,...

Article
Recent fMRI findings revealed that impairment in a serial prediction task in patients suffering from Parkinson's disease (PD) results from hypoactivity of the SMA. Furthermore, hyperactivity of the lateral premotor cortex sustained performance after withdrawal of medication. To further explore these findings, we here examined the impact of deep bra...
Article
Full-text available
Parkinson's disease (PD), which is caused by degeneration of dopaminergic neurons in the midbrain, results in a heterogeneous clinical picture including cognitive decline. Since the phasic signal of dopamine neurons is proposed to guide learning by signifying mismatches between subjects' expectations and external events, we here investigated whethe...
Article
Full-text available
Action recognition involves not only the readout of body movements and involved objects but also the integration of contextual information, e.g. the environment in which an action takes place. Notably, inferring superordinate goals and generating predictions about forthcoming action steps should benefit from screening the actor's immediate environm...
Article
Full-text available
Recognizing and understanding the actions of others is usually coupled with perceiving someone else's body movements from a third person perspective (3pp) whereas we perceive our own actions from a first person perspective (1pp). From a neural viewpoint, a recent finding is that perceiving actions from a 3pp as compared to a 1pp activates the tempo...
Article
Prediction errors are deemed necessary for the updating of internal models of the environment, prompting us to stop or assert current action plans and helping us to adapt to environmental features. The aim of the present study was twofold: First, we sought to determine the neural underpinnings of qualitatively different abstract prediction errors i...
Article
Surprising events may be relevant or irrelevant for behavior, requiring either flexible adjustment or stabilization of our model of the world and according response-strategies. Cognitive flexibility and stability in response to environmental demands have been described as separable cognitive states, associated with activity of striatal and lateral...
Article
Full-text available
Actions are recognized faster and with higher accuracy when they take place in their typical environments. It is unclear, however, when contextual cues from the environment become effectively exploited during childhood and whether contextual integration interacts with other factors such as children's perceptual or motor experience with an action. I...
Article
Specific spatial environments are often indicative of where certain actions may take place: In kitchens we prepare food, and in bathrooms we engage in personal hygiene, but not vice versa. In action recognition, contextual cues may constrain an observer's expectations toward actions that are more strongly associated with a particular context than o...
Article
Since everyday actions are statistically structured, knowing which action a person has just completed allows predicting the most likely next action step. Taking even more than the preceding action into account improves this predictability, but also causes higher processing costs. Using fMRI, we investigated whether observers exploit 2nd-order stati...
Article
Animals depend on predictions about the near future to react and act in a timely, situation-appropriate fashion. Prediction is particularly challenged in the face of events: these entail a stimulus whose temporally directed structure is meaningful in itself. Many simple events, e.g. regular motion, can be predicted by means of dynamic-forward extra...

Article
Prediction and expectation are part of the daily life, but underlying brain mechanisms remain obscure. Recent progress in this area results from a coalescence of computational, theoretical, and neuroscientific approaches that turn some of our concepts of perception and action upside down. Prediction turns out to be an integral principle of cortical...
Article
Action observation is known to trigger predictions of the ongoing course of action and thus considered a hallmark example for predictive perception. A related task, which explicitly taps into the ability to predict actions based on their internal representations, is action segmentation; the task requires participants to demarcate where one action s...
Article
Cognitive impairment in Parkinson's disease (PD) is often attributed to dopamine deficiency in the prefrontal-basal ganglia–thalamo-cortical loops. Although recent studies point to a close interplay between motor and cognitive abilities in PD, the so-called “motor loop” connecting supplementary motor area (SMA) and putamen has been considered solel...
Article
Full-text available
Actions performed by others are mostly not observed in isolation, but embedded in sequences of actions tied together by an overarching goal. Therefore, preceding actions can modulate the observer's expectations in relation to the currently perceived action. Ven-trolateral prefrontal cortex (vlPFC), and inferior frontal gyrus (IFG) in particular, is...
Article
Full-text available
The motor system is engaged when we perceive movement in the environment, even when we have no sensorimotor experience of that movement. It has been suggested that this ability relies on internal models that comprise specific exteroceptive representations, such as audition and vision. It has been shown that, for human movements, the quality of perc...
Article
Full-text available
Objects are reminiscent of actions often performed with them: knife and apple remind us on peeling the apple or cutting it. Mnemonic representations of object-related actions (action codes) evoked by the sight of an object may constrain and hence facilitate recognition of unrolling actions. The present fMRI study investigated if and how action cod...
Article
Full-text available
The present fMRI study investigated whether human observers spontaneously exploit the statistical structure underlying continuous action sequences. In particular, we tested whether two different statistical properties can be distinguished with regard to their neural correlates: an action step's predictability and its probability. To assess these pr...
Article
Actions observed in everyday life normally consist of one person performing sequences of goal-directed actions. The present fMRI study tested the hypotheses that observers are influenced by the actor's identity, even when this information is task-irrelevant, and that this information shapes their expectation on subsequent actions of the same actor....
Article
Not only committing errors, but also observing errors has been shown to activate the dorsal medial prefrontal cortex, particularly BA 8 and adjacent rostral cingulate zone (RCZ). Currently, there is a debate on whether this activity reflects a response to the incorrectness of the committed action or to its unexpectedness. This article reports two s...

Full-text available
Authenticity of vocal emotion expression affects emotion recognition and brain activity in the so-called Theory of Mind (ToM) network, which is implied in the ability to explain and predict behavior by attributing mental states to other individuals. Exploiting the variability of the fundamental frequency (F0 contour), which varies more (higher cont...
Article
Repeated experiences with an event create the expectation that subsequent events will expose an analog structure. These spontaneous expectations rely on an internal model of the event that results from learning. But what happens when events change? Do experience-based internal models get adapted instantaneously, or is model adaptation a function of...
Article
Traditionally, the lateral premotor cortex (PM) is assigned a role in stimulus-driven rather than memory-driven motor control, whereas the opposite holds for the mesial premotor cortex (supplementary motor area, SMA). Consistently, patients with Parkinson's Disease (PD), in which a specific functional degradation of the mesial loop (i.e. SMA-Striat...

Context has been found to have a profound effect on the recognition of social stimuli and correlated brain activation. The present study was designed to determine whether knowledge about emotional authenticity influences emotion recognition expressed through speech intonation. Participants classified emotionally expressive speech in an fMRI experim...

Abstract: Not only committing errors, but also observing errors has been shown to activate the dorsal medial prefrontal cortex, particularly BA 8 and adjacent rostral cingulate zone (RCZ). Currently, there is a debate on whether this activity reflects a response to the incorrectness of the committed action or to its unexpectedness. This article rep...
Article
While neural signatures of breaches of expectancy and their immediate effects have been investigated, thus far, temporally more remote effects have been neglected. The present fMRI study explored neural correlates of temporally remote destabilization of prediction following rare breaches of expectancy with a mean delay of 14 s. We hypothesized temp...

Influential concepts in neuroscientific research cast the brain a predictive machine that revises its predictions when they are violated by sensory input. This relates to the predictive coding account of perception, but also to learning. Learning from prediction errors has been suggested for take place in the hippocampal memory system as well as in...
Article
Full-text available
When we observe an action, we recognize meaningful action steps that help us to predict probable upcoming action steps. This segmentation of observed actions, or more generally events, has been proposed to rely in part on changes in motion features. However, segmentation of actions, in contrast to meaningless movements, may exploit additional infor...
Article
Full-text available
To recognize an action, an observer exploits information about the applied manipulation, the involved objects, and the context where the action occurs. Context, object, and manipulation information are hence expected to be tightly coupled in a triadic relationship (the COM triad hereafter). The current fMRI study investigated the hemodynamic signat...
Conference Paper
Human observers perceive movement with typical human kinematics more sensitively than movement with non-human kinematics, even when its velocity profile is more uniform. In a behavioural experiment and a subsequent fMRI study, we tested the influence of movement kinematics on the accuracy of predicting the time course of another individual’s action...
Article
Full-text available
The aim of the present study was to determine how authenticity of emotion expression in speech modulates activity in the neuronal substrates involved in emotion recognition. Within an fMRI paradigm, participants judged either the authenticity (authentic or play acted) or emotional content (anger, fear, joy, or sadness) of recordings of spontaneous...

Full-text available
Predicting the actions of other individuals is crucial for our daily interactions. Recent evidence suggests that the prediction of object-directed arm and full-body actions employs the dorsal premotor cortex (PMd). Thus, the neural substrate involved in action control may also be essential for action prediction. Here, we aimed to address this issue...
Article
This chapter examines the role of the inferior ventral premotor cortex in rhythm prediction. It discusses the results of studies which used functional magnetic resonance imaging (fMRI) technique to understand the neural basis for rhythm prediction. These studies analysed brain activation during the prediction of upcoming stimuli and the moment of s...
Article
Action observation engages higher motor areas, possibly reflecting an internal simulation. However, actions considered odd or unusual were found to trigger additional activity in the so-called theory of mind (ToM) network, pointing to deliberations on the actor's mental states. In this functional magnetic resonance imaging study, the hypothesis was...
Article
Most every day actions take place in domestic rooms that are specific for certain classes of actions. Contextual information derived from domestic settings may therefore influence the efficiency of action recognition. The present studies investigated whether action recognition is modulated by compatibility of the context an action is embedded in. T...
Article
Behavioral studies suggest that preference for a beat rate (tempo) in auditory sequences is tightly linked to the motor system. However, from a neuroscientific perspective the contribution of motor-related brain regions to tempo preference in the auditory domain remains unclear. A recent fMRI study (Kornysheva et al. [2010]: Hum Brain Mapp 31:48-64...
Article
Full-text available
Integrating auditory and motor information often requires precise timing as in speech and music. In humans, the position of the ventral premotor cortex (PMv) in the dorsal auditory stream renders this area a node for auditory-motor integration. Yet, it remains unknown whether the PMv is critical for auditory-motor timing and which activity increase...
Article
Many studies have shown the involvement of the premotor cortex in action observation, recognizing this region as the neural marker of action simulation (i.e., internal modeling on the basis of the observer's own motor repertoire). So far, however, we have remained unaware of how action simulation differs from more general action representation in t...
Article
Full-text available
The striatum has been established as a carrier of reward-related prediction errors. This prediction error signal concerns the difference between how much reward was predicted and how much reward is gained. However, it remains to be established whether general breaches of expectation, i.e., perceptual prediction errors, are also implemented in the s...
Article
Identifying and evaluating events which are novel in a particular environment is crucially important for adaptive behavior. These events are often not just novel, as they typically violate expectations which may be formulated based on numerous features of our surroundings, one of which includes the ordinal structure (temporal order) of relevant sti...
Chapter
Long-term planning and prediction have been suggested to be human faculties that we do not share with other species. Here, evidence for a neurofunctional gradation of prediction and planning functions is reviewed that is located in the frontal lobes and reflects a more or less continuous time scale. It shows that those parts of the gradation that r...

Zusammenfassung. Imitieren oder im Wortsinne nach-vollziehen können wir weder unbelebte Ereignisse, wie etwa anbrandende Meereswellen, noch nicht-humane belebte, wie einen vorbeilaufenden Hund. Wir können aber antizipieren, wie sie sich entwickeln, und neuere Studien zeigen, dass dabei unser motorisches System aktiv ist. Diese Phänomene sind erklär...

The lateral premotor cortex (PM) of the macaque monkey is an anatomically multifaceted area, which serves multiple sensorimotor and cognitive functions. While evidence for the functional organization of human premotor cortex accumulates, much less is known about the underlying anatomical properties of this brain region. We used diffusion tractograp...

Full-text available
The term "predictive brain" depicts one of the most relevant concepts in cognitive neuroscience which emphasizes the importance of "looking into the future", namely prediction, preparation, anticipation, prospection or expectations in various cognitive domains. Analogously, it has been suggested that predictive processing represents one of the fund...
Article
Identifying novel or unexpected events which violate predictions based on the regularities extracted from our environment is crucially important for adaptive behavior. However, the exact dynamics of processing such events is not well understood. Furthermore, it is not known in which degree the process of deviant detection differs across contexts an...
Article
Processing perceptual sequences relies on the motor system, which is able to simulate the dynamics of the environment by developing internal representations of external events and using them to predict the incoming stimuli. Although it has previously been demonstrated that such models may incorporate predictions based on exact stimulus properties a...

Listening to music can induce us to tune in to its beat. Previous neuroimaging studies have shown that the motor system becomes involved in perceptual rhythm and timing tasks in general, as well as during preference-related responses to music. However, the role of preferred rhythm and, in particular, of preferred beat frequency (tempo) in driving a...

With the aim of understanding how different mental or intentional states are processed in the brain, the present functional magnetic resonance imaging (fMRI) study examined the brain correlates during the ascription of belief intentional states relative to desire intentional states as well as the effect of incongruent relative to congruent intentio...
Article
Sequence processing has been investigated in a number of studies using serial reaction time tasks or simple artificial grammar tasks. Little, however, is known about higher-order sequence processing entailing the hierarchical organization of events. Here, we manipulated the regularities within sequentially occurring, non-linguistic visual symbols b...

Processing of relational information is a prerequisite underlying a number of higher cognitive faculties. Different brain regions within the frontal cortex have been implicated in supporting this function. The present study aimed at differentiating the roles of two frontal areas - anterior prefrontal cortex (aPFC) and premotor cortex (PMC) - in rel...

Lateralized processing of speech is a well studied phenomenon in humans. Both anatomical and neurophysiological studies support the view that nonhuman primates and other animal species also reveal hemispheric differences in areas involved in sound processing. In recent years, an increasing number of studies on a range of taxa have employed an orien...
