ABSTRACT: Associating reward to task performance has been shown to benefit scores of cognitive functions. Importantly, this typically entails associating reward to the execution of a response, hence intertwining action-related processes with motivational ones. However, recently, preparatory action requirements (go/no-go) and outcome valence (reward/punishment) were elegantly separated using a cued orthogonalized go/no-go task. Functional magnetic resonance imaging results from this task showed that typical areas of the ‘reward network’ like the dopaminergic midbrain and the striatum predominantly encode action rather than valence, displaying enhanced activity when preparing for action (go) compared to inaction (no-go). In the current study we used event-related potentials (ERPs) to probe for differences in preparatory state related to cognitive effort in this task, which has similarly been linked to “reward-network” activity. Importantly, the contingent negative variation (CNV), which is linked to effortful cognitive preparation processes during cue-target intervals, was clearly observed in go trials but not in no-go trials. Moreover, target-locked ERP results (N1 and P3) suggested that attention to the target was enhanced when an action had to be performed (go trials), and typical inhibition-related ERP components were not observed in no-go trials, suggesting a lack of active response inhibition. Finally, feedback-P3 results could suggest that correct feedback was valued more in motivated go trials, again implying that more effort was required to correctly perform the task. Together, these results indicate that the anticipation of action compared to inaction simultaneously entails differences in mental effort, highlighting the need for further dissociation of these concepts.Psychophysiology 10/2015;

ABSTRACT: Dyspnea anticipation and perception varies largely between individuals. To investigate whether genetic factors related to negative affect such as the 5-HTTLPR polymorphism impact this variability, we investigated healthy, 5-HTTLPR stratified volunteers using resistive load induced dyspnea together with fMRI. Alternating blocks of severe and mild dyspnea ("perception") were differentially cued ("anticipation") and followed by intensity and unpleasantness ratings. In addition, volunteers indicated their anticipatory fear during the anticipation periods. There were no genotype-based group differences concerning dyspnea intensity and unpleasantness or brain activation during perception of severe vs. mild dyspnea. However, in risk allele carriers, higher anticipatory fear was paralleled by stronger amygdala activation during anticipation of severe vs. mild dyspnea. These results suggest a role of the 5-HTTLPR genotype in fearful dyspnea anticipation. © 2015 Society for Psychophysiological Research.Psychophysiology 02/2015; 52(7). DOI:10.1111/psyp.12417

ABSTRACT: How dimensions of emotion affect respiratory regulation assessed by respiratory variability and sighing is unknown. The present studies aimed to investigate the effects of emotional valence and arousal on respiratory variability and sigh rate. Within subjects, emotions were induced by picture viewing in a first experiment, and script-driven mental imagery in a second experiment. Respiration was measured throughout the experiment, while valence, arousal, and dominance ratings were assessed after each trial. Negative and/or high-arousal emotions increased sigh rates and respiratory variability during picture viewing and imagery. Only depression imagery, however, decreased correlated variability (and only in minute ventilation). Fear imagery particularly increased variability in end-tidal carbon dioxide and expiratory time. These findings show that dimensions of emotion importantly influence respiratory regulation. Copyright © 2014 Society for Psychophysiological Research.Psychophysiology 12/2014; 52(5).

ABSTRACT: Elevated inflammatory levels are linked to poorer cognition, but experimental confirmation is lacking. This report examined associations between cognitive performance and inflammation induced by exercise and vaccination. Thirty-six (exercise N = 18, vaccination N = 18) healthy males completed a paced auditory serial addition test (PASAT), which is a multifaceted measure of cognitive function. The task was completed in placebo and elevated inflammation states. Improvements in PASAT performance were related to inflammation. In the exercise study, IL-6 during the first PASAT negatively correlated with PASAT improvement (p = .022). In the vaccination study, increases in C-reactive protein between PASATs correlated with reduced PASAT improvement (p < .001). Inflammation was linked to reduced improvements in cognitive performance. Further research should identify the specific cognitive functions affects and the underlying mechanisms.Psychophysiology 11/2014; 52(3). DOI:10.1111/psyp.12360
Article: Attenuation of auditory[Show abstract] [Hide abstract]
ABSTRACT: The event‐related potential (ERP) correlates of sound detection are attenuated when eliciting sounds coincide with our own actions. The role of attention in this effect was investigated in two experiments by presenting tones separated by random intervals. In the homogeneous condition of Experiments 1 and 2, the same tone was repeated, whereas in the mixed condition of Experiment 1, tones with five different frequencies were presented. Participants performed a time‐interval production task by marking intervals with keypresses in Experiment 1, and tried to produce keypress‐tone coincidences in Experiment 2. Although the auditory ERPs were attenuated for coincidences, no modulation by the multiplicity of tone frequencies in Experiment 1, or by the task‐relevancy of tones and coincidences in Experiment 2, was found. This suggests that coincidence‐related ERP attenuation cannot be fully explained by voluntary attentional mechanisms.Psychophysiology 01/2013; 50(3).
Article: Overcoming limitations of the[Show abstract] [Hide abstract]
ABSTRACT: The usefulness of the event‐related potential (ERP) method can be compromised by violations of the underlying assumptions, for example, confounding variations of latency and amplitude of ERP components within and between conditions. Here we show how the ERP subtraction method might yield misleading information due to latency variability of ERP components. We propose a solution to this problem by correcting for latency variability using Residue Iteration Decomposition (RIDE), demonstrated with data from representative go/no‐go experiments. The overlap of N2 and P3 components in go/no‐go data gives rise to spurious topographical localization of the no‐go–N2 component. RIDE decomposes N2 and P3 based on their latency variability. The decomposition restored the N2 topography by removing the contamination from latency‐variable late components. The RIDE‐derived N2 and P3 give a clearer insight about their functional relevance in the go/no‐go paradigm.Psychophysiology 01/2013; 50(3).
Article: Reliability of the[Show abstract] [Hide abstract]
ABSTRACT: Event‐related potential (ERP) studies of error‐processing have characterized the error‐related negativity (ERN) as a negative deflection occurring after the commission of an error at frontocentral sites. The ERN has frequently been examined in the context of individual differences and has been proposed as a neurobehavioral risk marker. Given this, it is important to characterize the psychometric properties of the ERN across multiple tasks as a function of increasing trial numbers in order to establish task‐specific psychometric properties for efficient assessments in clinical or applied settings. The current study examines the internal reliability of the ERN across the flankers, Stroop, and go/no‐go tasks as a function of error number. Results suggest that although the tasks all elicit the ERN reliably, important psychometric differences emerged indicating that the flankers task might be prioritized when assessing the ERN.Psychophysiology 01/2013; 50(12).
Article: Proactive and reactive control in[Show abstract] [Hide abstract]
ABSTRACT: We investigated how proactive and reactive control facilitates performance in mixed stimulus–response compatibility (SRC) tasks. SRC effects were eliminated in mixed tasks and reversed following incompatible trials. In mixed tasks, early preferential response activation was present in stimulus‐locked lateralized readiness potentials (LRPs) but reduced following incompatible trials. In event‐related potentials (ERPs), stimulus‐locked N2 was enhanced in all mixed trials but was not significantly influenced by the preceding trial. A response‐locked fronto‐central negative component (N‐120), peaking just before the response, was largest for mixed compatible trials preceded by incompatible trials. This N‐120 was paired with an enhancement to the peak of the response‐locked LRP. Proactive control is involved in selection of an S‐R mapping via the indirect route of a dual‐route model. Reactive control corrects the S‐R mapping, particularly when alternating between S‐R mappings.Psychophysiology 01/2012; 49(6).

ABSTRACT: We aimed to investigate whether fear of suffocation predicts healthy persons' respiratory and affective responses to obstructed breathing as evoked by inspiratory resistive loads. Participants (N = 27 women, ages between 18 and 21 years) completed the Fear of Suffocation scale and underwent 16 trials in which an inspiratory resistive load of 15 cmH2O/l/s (small) or 40 cmH2O/l/s (large) was added to the breathing circuit for 40 s. Fear of suffocation was associated with higher arousal ratings for both loads. Loaded breathing was associated with a decrease in minute ventilation, but progressively less so for participants scoring higher on fear of suffocation when breathing against the large load. The present findings document a potentially panicogenic mechanism that may maintain and worsen respiratory discomfort in persons with fear of suffocation.Psychophysiology 01/2012; 49(6).
Article: Combining the[Show abstract] [Hide abstract]
ABSTRACT: Despite the P300‐Concealed Information Test's validity in detecting concealed memory when it is conducted immediately after the mock crime, whether the P300‐CIT's detection efficiency is moderated by time delay remains unknown. Here, we conducted a mock crime study in which guilty participants were tested immediately after the mock crime or 1 month later. An innocent group was also tested. Assuming that the autobiographical Implicit Association Test (aIAT) and the P300‐CIT rely on nonoverlapping mechanisms for memory detection, participants were tested using both the P300‐CIT and the reaction time (RT)–based aIAT. Results suggested that the sensitivity of both tests remains even after the 1‐month delay. The indicators from the RT‐aIAT and P300‐CIT were uncorrelated, thus combining P300‐CIT and aIAT data further increased the efficiency of memory detection.Psychophysiology 01/2012; 49(8).
