Emotional Information Processing

Implicit motives play an important role in the regulation of many basic cognitive processes, particularly in the stage of attention. We conducted a study with a sample of 58 college students to examine selective attention to emotional stimuli as a function of individual differences in the implicit need for affiliation (nAff). In an affective oddball paradigm, event-related potentials were recorded while participants viewed positive, neutral, and negative images of people. Results showed that individuals high in nAff elicited larger late positive potential amplitudes to negative images than those low in nAff did. These findings replicate and extend the results of a previous study focused on these relationships and provide additional information on the neural correlates of affiliation-related emotional information processing.

Abstract Background Deficits in event-related potential (ERP) including duration mismatch negativity (MMN) and P3a have been demonstrated widely in chronic schizophrenia (SZ) but inconsistent findings were reported in first-episode patients. Psychotropic medications and diagnosis might contribute to different findings on MMN/P3a ERP in first-episode patients. The present study examined MMN and P3a in first episode drug naïve SZ and bipolar disorder (BPD) patients and explored the relationships among ERPs, neurocognition and global functioning. Methods Twenty SZ, 24 BPD and 49 age and sex-matched healthy controls were enrolled in this study. Data of clinical symptoms [Positive and Negative Symptoms Scale (PANSS), Young Manic Rating Scale (YMRS), Hamilton Depression Rating Scale (HAMD)], neurocognition [Wechsler Adult Intelligence Scale (WAIS), Cattell's Culture Fair Intelligence Test (CCFT), Delay Matching to Sample (DMS), Rapid Visual Information Processing (RVP)], and functioning [Functioning Assessment Short Test (FAST)] were collected. P3a and MMN were elicited using a passive auditory oddball paradigm. Results Significant MMN and P3a deficits and impaired neurocognition were found in both SZ and BPD patients. In SZ, MMN was significantly correlated with FAST (r = 0.48) and CCFT (r = −0.31). In BPD, MMN was significantly correlated with DMS (r = −0.54). For P3a, RVP and FAST scores were significant predictors in SZ, whereas RVP, WAIS and FAST were significant predictors in BPD. Conclusions The present study found deficits in MMN, P3a, neurocognition in drug naïve SZ and BPD patients. These deficits appeared to link with levels of higher-order cognition and functioning.

Benzodiazepines have been used in the pharmacological treatment of anxiety for over four decades. However, very few studies have combined bromazepam and event-related potentials (ERP). The present study aimed at investigating the modulatory effects of this drug on brain dynamics. Specifically, the effects of bromazepam (3mg) on the P300 component of the ERP were tested in a double-blind experiment. The sample, consisting of 15 healthy subjects (7 male and 8 female), was submitted to a visual discrimination task, which employed the "oddball" paradigm. Electrophysiological (P300) and behavioral measures (stroop, digit span, and reaction time) were analyzed across three experimental conditions: placebo 1, placebo 2, and bromazepam. Results suggest that the effects of bromazepam (3mg) on cognitive processes are not apparent. In spite of what seems irrefutable in current literature, bromazepam did not produce evident effects on the behavioral and electrophysiological variables analyzed.

Familial segregation is a norm rather than an exception in psychiatry. Genetic research has failed to provide much anticipated unanimous, if not awaited answers to the complex predispositions to psychiatric disorders. Hence, the concept of endophenotype took birth. Endophenotype is an attribute which is hidden phenotype, which is described as internal phenotypes discoverable by biochemical test or microscopic examination. This concept was immediately picked up by psychiatry, giving a totally new direction to the search for root cause of various psychiatric disorders.Cognitive deterioration is inseparable from psychiatric disorders, known since dawn of psychiatry. However, cognitive deficits in FDRs (First Degree Relatives) of psychiatric patients were one of the first endophenotypes noted. Event Related Potential (ERP), a science known to be electrophysiological counterpart of various cognitive processes, was soon incorporated in search of endophenotypes in psychiatry. In schizophrenia reduced amplitude of MMN(Mismatch negativity), impaired suppression of P50 and reduced amplitude of P300; reduced P300 amplitude, impaired P50 suppression in Bipolar Affective Disorders; reduced P300 amplitude in substance dependence disorders have been reported to have endophenotypic values. Various other ERP waves such as CNV, N400 have been investigated but no conclusive reports are out yet. The ultimate goal of this science is to search for genes governing the cognitive processes responsible for ERP waves identified as Endophenotypes for specific psychiatric disorders, and the search has just started.Keywords : Event Related Potential, Endophenotype, Psychiatric Disorder, Mismatch negativity,P 300, P 50, CNV

In this randomized, double-blind, three-period crossover trial, 24 healthy volunteers without migraine received zolmitriptan 5 mg, dexfenfluramine 15 mg or placebo orally. At 2, 6, and 24 h postdose, auditory stimuli of 1000 Hz (nontarget tone) and 2000 Hz (target tone) were randomly and binaurally presented in an active oddball paradigm (4:1 ratio). Cortical auditory evoked responses were recorded for 500 msec poststimulus. Plasma concentrations of zolmitriptan and a 17-lead quantitative EEG were assessed at the same timepoints. Relative to placebo, zolmitriptan reduced the maximum absolute amplitude, amplitude difference (from nontarget tone noise) and area under the curve of the cortical auditory target tone event-related potential (P300 ERP). The most dramatic effect of zolmitriptan was to diminish the point estimate of noise during the 200-400 msec poststimulus epoch. The effect of zolmitriptan appeared concentration dependent. The latency of the P300 ERP was unaffected by zolmitriptan and there was no clinically significant effect on the EEG. Modification by zolmitriptan of the cortical electrical activity evoked by auditory stimuli confirms a central action of this drug in humans, which appears to affect cortical information processing without global alteration of the quantitative EEG.

We do not know enough about the cognitive background of creativity despite its significance. Using an active oddball paradigm with unambiguous and ambiguous portrait paintings as the standard stimuli, our aim was to examine whether: creativity in the figural domain influences the perception of visual stimuli; any stages of visual processing; or if healthy aging has an effect on these processes. We investigated event related potentials (ERPs) and applied ERP decoding analyses in four groups: younger less creative; younger creative; older less creative; and older creative adults. The early visual processing did not differ between creativity groups. In the later ERP stages the amplitude for the creative compared with the less creative groups was larger between 300 and 500 ms. The stimuli types were clearly distinguishable: within the 300–500 ms range the amplitude was larger for ambiguous rather than unambiguous paintings, but this difference in the traditional ERP analysis was only observable in the younger, not elderly groups, who also had this difference when using decoding analysis. Our results could not prove that visual creativity influences the early stage of perception, but showed creativity had an effect on stimulus processing in the 300–500 ms range, in indexing differences in top-down control, and having more flexible cognitive control in the younger creative group.

Purpose: This study was to determine the effects of response tasks, such as button pressing and mental counting, and handedness on N100, N200, and P300 auditory event-related potential (AERP).Methods: A total of 50 normal-hearing young adults with the average age of 21.6 (±1.5) years participated in this study. Among them, 15 men and 15 women were right-handed and 10 men and 10 women were left-handed. An oddball paradigm was used to deliver 30 stimuli of 2 kHz target tone bursts and 120 stimuli of 1 kHz nontarget tone bursts. The stimuli were presented at 70 dB sound pressure level with the rate of 1/s.Results: The button pressing task elicited significantly smaller N100 and larger P300 amplitudes than the mental counting task. N200 latency was significantly lower and P300 amplitude was higher in left-handed participants than those who are right-handed. Appearance percentages of right-/left-handed participants for N100, N200, and P300 were 80/95%, 85/85%, and 75/75% for the button pressing task and 80/90%, 80/80%, and 70/70% for mental counting task, respectively.Conclusion: The significant difference in appearance percentage between response tasks supported that P300 was a strong endogenous potential. N100 and N200 were thought to have both endogenous and exogenous characteristics. A more sensitive approach in selecting the task of response for the target stimuli and careful consideration for the handedness is necessary for AERP recordings.

Objectives: We investigated the auditory cognitive and behavioral functions during 2nd and 3rd trimesters of pregnancy using event-related potentials (ERPs) and different neuropsychology tests, respectively. Methods: The ERPs were studied by using a 128-sensor net, and PAS/COWA, WCST, ZCT, RAVLTIM/RAVLTDR/RAVLTTS, and BDI were tested for neuropsychology assessment. Total 39 subjects were recruited for control group (G1, n=15, non-pregnant), 2nd trimester group (G2, n=12, 13-26 weeks gestation), and 3rd trimester group (G3, n=12, 26- 40 weeks gestation). Auditory oddball paradigm was used during ERP study. Subjects silently counted only the target stimuli with attention by ignoring standard stimuli. Value of the mean differences of the target and standard stimuli were measured across groups in 10-20 electrode systems. Results: The P50, N100, and P300 ERP components were analyzed. The G3 (at F7 and C3) and G2 (at T4) groups evoked the highest significant amplitudes in P50, and G3 (at Cz and Pz) and G1 (at F8 and T4) evoked the highest significant amplitudes of N100 with significantly prolonged latencies at Cz and O1 (in G1) and F8 (in G2). However, significantly higher amplitudes of P300 were found at Fz (in G3) and FP1 (G2) (G2>G3). On the other hand, neuropsychology tests revealed that G2 possessed the highest significant score in WCST and G1 in ZCT. The G3 performed poorly in all tests. Conclusion: We concluded that pregnant groups performed better in auditory (attention/memory) and executive function assessment. Moreover, the 2nd trimester group has better auditory cognitive function compared to the 3rd trimester group due to the effect of hormonal changes during pregnancy, which might be a positive influence during the pregnancy period.

Potential Component

Nicotine is a psychoactive substance that is commonly consumed in the context of music. However, the reason why music and nicotine are co-consumed is uncertain. One possibility is that nicotine affects cognitive processes relevant to aspects of music appreciation in a beneficial way. Here we investigated this possibility using Event-Related Potentials. Participants underwent a simple decision-making task (to maintain attentional focus), responses to which were signalled by auditory stimuli. Unlike previous research looking at the effects of nicotine on auditory processing, we used complex tones that varied in pitch, a fundamental element of music. In addition, unlike most other studies, we tested non-smoking subjects to avoid withdrawal-related complications. We found that nicotine (4.0 mg, administered as gum) increased P2 amplitude in the frontal region. Since a decrease in P2 amplitude and latency is related to habituation processes, and an enhanced ability to disengage from irrelevant stimuli, our findings suggest that nicotine may cause a reduction in habituation, resulting in non-smokers being less able to adapt to repeated stimuli. A corollary of that decrease in adaptation may be that nicotine extends the temporal window during which a listener is able and willing to engage with a piece of music.

Neural Marker

Purpose This study explored the neural marker indexing deficits in discriminating lexical tone changes in Mandarin-speaking children with developmental language disorders (DLDs) using mismatch negativity, an event-related potential component for auditory change detection. Mandarin has four lexical tones characterized by a high-level tone (T1), high-rising tone (T2), low-dipping tone (T3), and high-falling tone (T4), in which the T2/T3 contrast is acoustically less discriminable in developmental groups. Therefore, this study further examined how deficits in children with DLD would vary with tonal contrasts' acoustic saliency. Method Event-related potentials were measured using the multideviant oddball paradigm described by Lee et al. (2012), who used Mandarin syllables [i] in T3 as the standard sound (80%), T1 as the large deviant (10%), and T2 as the small deviant (10%). Twelve children with DLD aged between 4 and 6 years participated in this study, and 12 age-matched children with typical development were selected from the data set of Lee et al. (2012) as the controls. Results The T1/T3 change elicited adultlike mismatch negativity in both the DLD and control groups, while no group difference was revealed. The T2/T3 change elicited a robust positive mismatch response (P-MMR) in children with DLD, while the P-MMR was less significant in the control group. The group comparisons revealed a larger P-MMR in children with DLD than in the control group. Furthermore, children with lower scores in language assessments tend to reveal larger P-MMRs. Conclusions This study demonstrated that deficits in children with DLD in discriminating subtle lexical tone changes reflect greater positivity of P-MMR to T2/T3 change. This implies that MMR to T2/T3 may serve as a neural marker for evaluating language delay in preschoolers.

Target Words

Pseudowords (words without semantic meaning) are often used as a control condition in linguistic cognitive experiments, with the expectation that such words, unlike real words, do not activate higher cognitive processes in the brain. However, other theories assume that pseudowords are perceived as new words, leading to an even higher cognitive response. The aim of this study was to investigate the cognitive load of processing a pseudoword by observing event-related potentials in a 3-stimulus oddball paradigm using real target words, real non-target words, and pseudowords as oddball stimuli. The results show a clear task-related P3b triggered by target words, but also a prominent P600 component triggered by pseudowords, indicating difficulty in the classification task due to unknown words. Surprisingly, N400 was decreased for pseudowords compared to target and non-target words at the locations where P3b and P600 were observed, suggesting that task-related effects might inhibit other aspects of cognitive processing. These results could lead to better understanding of the components that may overlap temporally and topographically, and to the more precise control of different cognitive generators involved in event-related potential experiments in pseudowords.
