title: No evidence for confounding orientation-dependent fixational eye movements under baseline conditions

description: Decoding has become a standard analysis technique for contemporary cognitive neuroscience. Already more than a decade
ago, it was shown that orientation information could be decoded from functional magnetic resonance imaging voxel time series.
However, the underlying neural mechanism driving the decodable information is still under debate. Here, we investigated
whether eye movements and pupil dilation during attempted fixation and passive viewing of visually presented square-wave
grating stimuli could explain orientation decoding. We hypothesized that there are confounding orientation-dependent fixational
eye movements (e.g., microsaccades), which systematically alter brain activity, and hence can be the source of decodable
information. We repeated one of the original orientation decoding studies, but recorded eye movements instead of brain activity.
We found no evidence that stimulus orientation can be decoded from eye movements under baseline conditions, but cannot rule
out the potential confounding effect of eye movements under different conditions. With this study, we emphasize the importance,
and show the implications of such potential confounding eye movements for decoding studies and cognitive neuroscience in
general.

title: Task-dependent responses to muscle vibration during reaching

description: Feedback corrections in reaching have been shown to be task-dependent for proprioceptive, visual and vestibular perturbations, in line with predictions from optimal feedback control theory. Mechanical perturbations have been used to elicit proprioceptive errors, but have the drawback to actively alter the limb's trajectory, making it non-trivial to dissociate the subject's compensatory response from the perturbation itself. In contrast, muscle vibration provides an alternative tool to perturb the muscle afferents without changing the hands trajectory, inducing only changes in the estimated, but not the actual, limb position and velocity. Here, we investigate whether upper-arm muscle vibration is sufficient to evoke task-dependent feedback corrections during goal-directed reaching to a narrow versus a wide target. Our main result is that for vibration of biceps and triceps, compensatory responses were down-regulated for the wide compared to the narrow target. The earliest detectable difference between these target-specific corrections is at about 100 ms, likely reflecting a task-dependent feedback control policy rather than a voluntary response.

title: Vestibular modulation of visuomotor feedback gains in reaching

description: Humans quickly and sophisticatedly correct their movements in response to changes in the world, such as when reaching to a target that abruptly changes its location. The vigor of these movement corrections is time-dependent, increasing if the time left to make the correction decreases, which can be explained by Optimal feedback control (OFC) theory as an increase of optimal feedback gains. It is unknown if corrections for changes in the world are as sophisticated under full-body motion. For successful visually-probed motor corrections during full-body motion not only the motion of the hand relative to the body needs to be taken into account, also the motion of the hand in the world should be considered, because their relative positions are changing. Here, in two experiments, we show that visuomotor feedback corrections in response to target jumps are more vigorous for faster passive full-body translational acceleration than for slower acceleration, suggesting that vestibular information modulates visuomotor feedback gains. Interestingly, these corrections do not demonstrate the time-dependent characteristics that body-stationary visuomotor feedback gains typically show, such that an Optimal feedback control model fell short to explain them. We further show that the vigor of corrections generally decreased over the course of trials within the experiment, as if the sensorimotor system adjusted its gains when learning to integrate the vestibular input into hand motor control.

title: Beyond establishing involvement: quantifying the contribution of anticipatory alpha- and beta-band suppression to perceptual improvement with attention

description: Systems and cognitive neuroscience aim at understanding the neurophysiological mechanisms that underlie cognition and behavior. Many studies have revealed the involvement of many types of neural signals in diverse cognitive and behavioral phenomena. Here, we go beyond establishing such involvement and address two fundamental, yet largely unaddressed, questions: 1) exactly how much does a given neural signal contribute to a cognitive or behavioral phenomenon of interest; and 2) to what extent are distinct neural signals independently related to this phenomenon? We recorded brain activity using magnetoencephalography while human participants performed a cued somatosensory detection task. Using a novel method, we then quantified the contribution (in a predictive but not causal sense) of two well-established neural phenomena to the improvement in perception with attentional orienting. In our sample, the anticipatory suppression of extracranially recorded oscillatory - and -band amplitudes from contralateral primary somatosensory cortex could account for maximally 29

title: Theta oscillations locked to intended actions rhythmically modulate perception

description: Ongoing brain oscillations are known to influence perception, and to be reset by exogenous stimulations. Voluntary action is also accompanied by prominent rhythmic activity, and recent behavioral evidence suggests that this might be coupled with perception. Here, we reveal the neurophysiological underpinnings of this sensorimotor coupling in humans. We link the trial-by-trial dynamics of EEG oscillatory activity during movement preparation to the corresponding dynamics in perception, for two unrelated visual and motor tasks. The phase of theta oscillations (~4 Hz) predicts perceptual performance, even >1 s before movement. Moreover, theta oscillations are phase-locked to the onset of the movement. Remarkably, the alignment of theta phase and its perceptual relevance unfold with similar non-monotonic profiles, suggesting their relatedness. The present work shows that perception and movement initiation are automatically synchronized since the early stages of motor planning through neuronal oscillatory activity in the theta range.

title: Natural rewards, learning and risk-taking in psychopathy

description: Among the most extensively studied impairments observed in individuals with psychopathy are those related to the disturbed processing of reward and punishment in relation to different forms of learning and decision making. In general, research shows deficient responding to (predictors of) punishment, especially when facing a competing reward, as well as impaired learning and decision making following reward. However, a possibly crucial limitation of these studies is that the experimental rewards that were used may not have been ecologically valid, and consequently not relevant or motivationally significant for participants with psychopathy, particularly for those that were incarcerated. Therefore, in the current project two experimental tasks were employed using individualized rewards and their subjective values to study (1) passive avoidance and reversal learning (PasRev dataset), and (2) risky decision making (WoF dataset) in offenders with and without psychopathy, as well as healthy controls. The results showed that sufficient subjective value of reward facilitates acquisition but not response reversal in psychopathic offenders. However, although we did find psychopathic offenders to be guided more by pay-off sizes than probabilities, we did not find any effects of subjective reward value on overall risky decision making. These findings suggest that specific reinforcement learning impairments often found in individuals with psychopathy can be reduced with the use of personalized rewards.

Raw data files of each individual participant contain behavioral output from both experiments, either labeled PW or WP, depending on the order in which the two tasks were administered (PasRev-WoF, or WoF-PasRev). Data from each experimental task can be separated on different tabs using the appropriate VBA script that is also provided (see session nr and task order). For the PasRev dataset, raw EEG-data files of each individual participant are provided for each of the three experimental runs separately. In addition, spreadsheets with all behavioral and ERP data on which the reported analyses have been conducted are provided for each task separately. For the main analyses, the applied SPSS syntax is also provided.

title: Production Validation

description: Copy of abstract from: "Communicative intent modulates production and comprehension of actions and gestures: a Kinect study" Cognition, 2018
Actions may be used to directly act on the world around us, or as a means of communication. Effective communication requires the addressee to recognize the act as being communicative. Humans are sensitive to ostensive communicative cues, such as direct eye gaze (Csibra & Gergely, 2009). However, there may be additional cues present in the action or gesture itself. Here we investigate features that characterize the initiation of a communicative interaction in both production and comprehension.

We asked 40 participants to perform 31 pairs of object-directed actions and representational gestures in more- or less- communicative contexts. Data were collected using motion capture technology for kinematics and video recording for eye-gaze. With these data, we focused on two issues. First, if and how actions and gestures are systematically modulated when performed in a communicative context. Second, if observers exploit such kinematic information to classify an act as communicative.

Our study showed that during production the communicative context modulates space-time dimensions of kinematics and elicits an increase in addressee-directed eye-gaze. Naïve participants detected communicative intent in actions and gestures preferentially using eye-gaze information, only utilizing kinematic information when eye-gaze was unavailable.

Our study highlights the general communicative modulation of action and gesture kinematics during production but also shows that addressees only exploit this modulation to recognize communicative intention in the absence of eye-gaze. We discuss these findings in terms of distinctive but potentially overlapping functions of addressee directed eye-gaze and kinematic modulations within the wider context of human communication and learning.

title: L2 sentence processing

description: In sentences like “the mouse that chased the cat was hungry”, the syntactically correct interpretation (the mouse chases the cat) is contradicted by semantic and pragmatic knowledge. Previous research has shown that L1 speakers sometimes base sentence interpretation on this type of knowledge (so-called “shallow” or “good-enough” processing). We made use of both behavioral and ERP measurements to investigate whether L2 learners differ from native speakers in the extent to which they engage in “shallow” processing. German learners of Dutch as well as Dutch native speakers read sentences containing relative clauses (as in the example above) for which the plausible thematic roles were or were not reversed, and made plausibility judgments.

title: Task-dependent vestibular feedback responses in reaching

description: When reaching for an earth-fixed object during self-rotation, the motor system should appropriately integrate vestibular signals and sensory predictions to compensate for the intervening motion and its induced inertial forces. While it is well established that this integration occurs rapidly, it is unknown if vestibular feedback is processed dependent on the behavioral goal. Here, we studied whether vestibular signals evoke fixed responses with the aim to preserve the hand trajectory in space or are processed more flexibly, correcting trajectories only in task-relevant spatial dimensions. We used galvanic vestibular stimulation (GVS) to perturb reaching movements toward a narrow or a wide target. Results show that the same vestibular stimulation led to smaller trajectory corrections to the wide than the narrow target. We interpret this reduced compensation as a task-dependent modulation of vestibular feedback responses, tuned to minimally intervene with the task-irrelevant dimension of the reach. These task-dependent vestibular feedback corrections are in accordance with a central prediction of optimal feedback control theory and mirror the sophistication seen in feedback responses to mechanical and visual perturbations of the upper limb.

title: Tracking Syntactic Conflict Between Languages over the Course of L2 Acquisition:  A Cross-Sectional ERP Study

description: One challenge of learning a foreign language (L2) in adulthood is the mastery of syntactic structures that are implemented differently in L2 and one’s native language (L1). Here, we asked how L2 speakers learn to process syntactic constructions that are in direct conflict between L1 and L2, in comparison to structures without such a conflict. To do so, we measured EEG during sentence reading in three groups of German learners of Dutch with different degrees of L2 experience (from three to more than 18 months of L2 immersion) as well as a control group of Dutch native speakers. They read grammatical and ungrammatical Dutch sentences that, in the conflict condition, contained a structure with opposing word orders in Dutch and German (sentence-final double infinitives), and in the no-conflict condition, a structure for which word order is identical in Dutch and German (subordinate clause inversion). Results showed, first, that beginning learners showed N400-like signatures instead of the expected P600 for both types of violations, suggesting that in the very early stages of learning, different neuro-cognitive processes are employed compared to native speakers, regardless of L1-L2 similarity. In contrast, both advanced and intermediate learners already showed native-like P600 signatures for the no-conflict sentences. However, their P600 signatures were significantly delayed in processing the conflicting structure, even though behavioral performance was on a native level for both these groups and structures. These findings suggest that L1-L2 word order conflicts clearly remain an obstacle to native-like processing, even for advanced L2 learners.

title: Language selection errors in switching

description: Although bilingual speakers are very good at selectively using one language rather than another, sometimes language selection errors occur. We examined the relative contribution of top-down cognitive control and bottom-up language priming to these errors. Unbalanced Dutch-English bilinguals named pictures and were cued to switch between languages under time pressure. We also manipulated the number of same-language trials before a switch (long vs. short runs).

title: Enhanced self-reported affect and prosocial behaviour without differential physiological responses in mirror-sensory synesthesia

description: Mirror-sensory synesthetes mirror the pain or touch that they observe in other people on their own bodies. This type of synesthesia has been associated with enhanced empathy. We investigated whether the enhanced empathy of people with mirror-sensory synesthesia influences the experience of situations involving touch or pain and whether it affects their prosocial decision making. Mirror-sensory synesthetes (N=18, all female), verified with a touch-interference paradigm, were compared with a similar number of age-matched control individuals (all female). Participants viewed arousing images depicting pain or touch; we recorded subjective valence and arousal ratings, and physiological responses, hypothesizing more extreme reactions in synesthetes. The subjective impact of positive and negative images was stronger in synesthetes than in control participants; the stronger the reported synesthesia, the more extreme the picture ratings. However, there was no evidence for differential physiological or hormonal responses to arousing pictures. Prosocial decision making was assessed with an economic game assessing altruism, in which participants had to divide money between themselves and a second player. Mirror-sensory synesthetes donated more money than non-synesthetes, showing enhanced prosocial behaviour, and also scored higher on the Interpersonal Reactivity Index as a measure of empathy. Our study demonstrates the subjective impact of mirror-sensory synesthesia and its stimulating influence on prosocial behaviour.
