Difficulties in emotion regulation, particularly in using adaptive regulation strategies such as cognitive reappraisal, are a commonly observed correlate of paranoia. While it has been suggested that poor implementation of cognitive reappraisal in dealing with aversive events precedes the onset of subclinical paranoid thinking, there is little empirical research on neural activation patterns during cognitive reappraisal efforts that might indicate vulnerability towards paranoid thinking. Prefrontal EEG alpha asymmetry changes were recorded while n = 57 participants were generating alternative appraisals of anger-eliciting events, and were linked to a behavioral measure of basic cognitive reappraisal capacity and self-reported paranoia proneness (assessed by personality facets of hostility and suspiciousness; Personality Inventory for DSM-5)...

Bilingual experience alters brain structure and enhances certain cognitive functions. Bilingualism can also affect mathematical processing. Reduced accuracy is commonly reported when arithmetic problems are presented in bilinguals' second (L2) vs. first (L1) language. We used MEG brain imaging during mental addition to characterize spatiotemporal dynamics during mental addition in bilingual adults. Numbers were presented auditorally and sequentially in bilinguals' L1 and L2, and brain and behavioral data were collected simultaneously...

R Rachel Weintraub-Brevda, Elizabeth F Chua
Previous research suggests that the left VLPFC is involved in working memory, whereas right VLPFC is involved with subsequent episodic memory. High-Definition Transcranial Direct Current Stimulation (HD-tDCS) was used to test whether excitation of the left or right VLPFC would show differential effects of negative and neutral stimuli on working memory and episodic memory tasks. While receiving HD-tDCS over the left or right VLPFC or sham stimulation, participants completed a working memory task with negative and neutral distractors followed by a surprise recognition test for the distractors...

Sleep loss has a major effect on cognitive tasks that are dependent on the maintenance of active sustained attention. This study examines the effects of sleep deprivation on automatic information processing, more specifically, its effect on processes leading to involuntary auditory attention capture by task-irrelevant auditory events. Two experiments were run. In the first, 13 participants were totally sleep-deprived (TSD); in the second, 16 participants were partially sleep-deprived (PSD), sleeping only four hours...

Reinforcer pathology theory stipulates that individuals with both (a) high preference for smaller, immediate over larger, delayed rewards; and (b) high demand for unhealthy commodities are uniquely susceptible to poor health outcomes. Specifically, two behavioral economic tasks (delay discounting, assessing preference for smaller, immediate or larger, delayed rewards; and purchasing, assessing purchases of commodities over changes in price) have been independently associated with conditions such as overweight/obesity and problem substance use...

Intra-Subject Variability (ISV), a potential index of catecholaminergic regulation, is elevated in several disorders linked with altered dopamine function. ISV has typically been defined as reaction time standard deviation. However, the ex-Gaussian and spectral measures capture different aspects and may delineate different underlying sources of ISV; thus reflecting different facets of the construct. We examined the impact of factors associated with dopamine metabolism, namely, Catechol-O-Methyltransferase Val158Met (COMT) genotype and Working Memory (WM) and response-switching on ISV facets in young healthy adults...

Bilateral eye movements (EMs) have been associated with enhancements in episodic memory and creativity. We explored the influence of EMs on behavior and event related potential (ERP) responses during the Attention Network Test (ANT). Participants completed ANT trials after bilateral EMs or a center-fixation control manipulation. We examined condition (EM, control) and handedness (consistent, inconsistent) differences for overall task performance, as well as alerting, orienting, and executive attention networks...

We studied the electrophysiological correlates of verbal humor comprehension by comparing Event Related Potentials (ERPs) and time-frequency representations recorded while 50 participants read humorous and non-humorous passages. Using linear mixed models on single trials we showed that humorous target words elicited a larger Left Anterior Negativity (LAN), sustained in time and followed by a positive shift involving P600 and Late Positive Complex (LPC) components. In the time-frequency domain, humor was associated with a power decrease in the beta-band of the EEG...

Acute stress influences reward-seeking tendencies and risky decision-making. However, it is unclear how acute stress influences decision-making in situations in which individuals must learn to either maximize long-term or immediate rewards from experience. Consequently, this study sought to investigate whether acute stress enhances salience of small, immediate or large, delayed rewards on decision-making under uncertainty. The Socially Evaluated Cold Pressor Task (SECPT) was used to induce acute stress. Participants in Experiment 1 (N = 50) were exposed to either the SECPT or a warm-water control condition and then completed a decision-making task in which participants needed to learn to forego immediate rewards in favor of larger delayed rewards...

Military personnel and emergency responders perform cognitively-demanding tasks during periods of sustained physical exertion and limited caloric intake. Cognitive function is preserved during short-term caloric restriction, but it is unclear if preservation extends to combined caloric restriction and physical exertion. According to the "reticular-activating hypofrontality" model, vigorous exertion impairs prefrontal cortex activity and associated functions. This double-blind, placebo-controlled, crossover study examined cognitive function during sustained exertion while volunteers were calorically-deprived...

Inhibitory control deficits represent a key aspect of the cognitive declines associated with aging. Practicing inhibitory control has thus been advanced as a potential approach to compensate for age-induced neurocognitive impairments. Yet, the functional brain changes associated with practicing inhibitory control tasks in older adults and whether they differ from those observed in young populations remains unresolved. We compared electrical neuroimaging analyses of ERPs recorded during a Go/NoGo practice session with a Group (Young; Older adults) by Session (Beginning; End of the practice) design to identify whether the practice of an inhibition task in older adults reinforces already implemented compensatory activity or reduce it by enhancing the functioning of the brain networks primarily involved in the tasks...

Older adults demonstrate greater susceptibility to high-confidence memory distortions. Cognitive processes underlying memory errors in older adults remain unclear. Here, in a categorized pictures paradigm, we used the event-related potential (ERP) to examine the electrophysiological correlates of false recognition. Young and older participants were presented with categorized pictures during study and subsequently completed an old/new recognition memory task that included studied pictures, lure pictures from studied categories, and new pictures...

The n-back task is a classical paradigm for functional neuroimaging studies of working memory (WM). The frontal and parietal cortical regions are known to be activated during the task. We used activation likelihood estimation (ALE) to conduct a quantitative meta-analysis of 96 primary studies of n-back task variants based on four conditions: memory loads (1-back, 2-back), object (identity, location), age (younger, older) and gender (male, female). Six cortical regions were consistently activated across all the studies: bilateral middle frontal gyrus (BA 10); bilateral inferior parietal lobule (BA 40); bilateral precuneus (BA 7); left superior frontal gyrus (BA 6); left anterior insula (aI) (BA 13); bilateral thalamus...

This study investigates the mental rotation performance of right- and left-handers on a chronometric mental rotation task. Hand preference as well as different types of hand performance were measured. Previous studies have reported slightly better mental rotation performance in right-handers compared with left-handers. However, different forms of hand performance were not considered in these studies. In this research, 61 participants completed a chronometric mental rotation task with cube figures. Handedness was measured using the Edinburgh Handedness Inventory, finger tapping, grip strength and the Grooved Pegboard Test...

Biomarkers indicating characteristic alterations in the brains of pain patients would in comparison to behavioral examinations allow for earlier diagnoses of pain disease development, a more immediate monitoring of pain disease progression, and for the development of interventions to reverse or compensate for the alterations. To reveal causal relations between an observed alteration and the pain disease longitudinal examinations are essential. Resting-state fMRI examinations can readily be included in large longitudinal cohorts allowing to achieve sufficiently large patient samples even for rare diseases...

This study investigated electroencephalography (EEG) correlates of prediction error during probabilistic learning in pre-adolescents. The detection of prediction errors, the discrepancies between experienced and anticipated outcomes, is thought to be a critical mechanism that drives new learning. Thirty-three typically developing pre-adolescents (mean age = 10.62 years) participated in an associative learning task in which they learned the probabilistic relationships between cues and outcome stimuli in the absence of explicit feedback...

The purpose of this study was to investigate the occurrence of an endogenously-evoked no-go N2b. Previous literature focused on the N2b being evoked by exogenous auditory stimuli. In this study, no-go stimuli were the absence of a gap in a 1000-ms noise burst (i.e., no-gap trials). ERPs were measured from 35 participants while performing a gap-detection task and passively listening to the same stimuli. Participants were asked to press a button when they heard a gap in the noise burst (go trials) and to withhold their button press when they did not perceive a gap in the noise burst (no-go trials)...

Recent research has focused on measuring neural correlates of metacognitive judgments in decision and post-decision processes during memory retrieval and categorization. However, many tasks (e.g., stimulus detection) may require monitoring of earlier sensory processing. Here, participants indicated which of two intervals contained an 80-ms pure tone embedded in white noise. One frequency (e.g., 1000 Hz) was presented on ∼80% of all trials (i.e., 'primary' trials). Another frequency (e.g., 2500 Hz) was presented on ∼20% of trials (i...

Listeners remember vocal melodies better than instrumental melodies, but the origins of the effect are unclear. One explanation for the 'voice advantage' is that general perceptual mechanisms enhance processing of conspecific signals. An alternative possibility is that the voice, by virtue of its expressiveness in pitch, simply provides more musical information to the listener. Individuals with congenital amusia provide a unique opportunity to disentangle the effects of conspecific status and vocal expressiveness because they cannot readily process subtleties in musical pitch...
