Event related brain potentials (ERPs) provide information about cortical processing in severe neurological patients whose cognitive abilities cannot be expressed in their behavior. In coma, ERPs contribute to the prediction of the outcome. In a vegetative state, ERPs uncover the functional state of cortical processes. The significance of ERPs in the neurophysiological study of consciousness is discussed.

Abstract In accounting, enterprise resource planning system is the database software package for supporting all corporations’ operations and processes such as marketing, human resources, finance, manufacturing, and several others. ERPS stores different forms of data for various computerized functions in a single database, user interface, and application. Although ERPS were initially utilized by huge manufacturing corporations, they are currently used by all sizes of businesses. Therefore, there is a need to identify the performance advantages that businesses gain from ERPS together with its impact on the performance of a firm. The goal of the research is to offer insights regarding the implementation of ERPS and their influence on organizational performance. The study will determine the benefits of ERPS, identify if there is a reliable or valid performance measurement system that connects ERPS to the performance of the organization, identify if ERPS have a positive effect on the performance of a company in the time periods after implementation and finally set the success factors accountable for the ERPS benefits. Accordingly, the study will establish the effect of ERPS on the performance of a company. The study will be a quantitative research where questionnaires will be used to collect the primary data. Purposive sampling will be used to obtain 50 answers from accounting experts so that to evaluate the effect of ERPS on financial performance and auditing of Lebanese firms. Moreover, financial performance indicators will be used to assess the overall company performance together with supply-chain operations. Quantitative analysis of data will be done through the use of SPSS based on the research objectives.

Introduction Enhanced recovery programmes (ERPs) reduce patient morbidity and mortality, and provide significant cost savings by reducing length of stay. Currently, no uniform ERP guidelines exist for lower limb arthroplasty in the UK. The aim of this study was to identify variations in ERPs and determine adherence to local policy. Methods Hospitals offering elective total knee arthroplasty (TKA) and total hip arthroplasty (THA) (23 and 22 centres respectively) contributed details of their ERPs, and performed an audit (15 patients per centre) to assess compliance. Results Contrasting content and detail of ERPs was noted across centres. Adherence to ERPs varied significantly (40–100% for TKA, 17–94% for THA). Analysis identified perioperative use of dexamethasone, tranexamic acid and early mobilisation for TKA, and procedures performed in teaching hospitals for THA as being associated with a reduced length of stay. Conclusions This study highlights variation in practice and poor compliance with local ERPs. Given the proven benefits of ERPs, evidence-based guidelines in the context of local skillsets should be established to optimise the patient care pathway.

SummaryOver the past 15 years, researchers have shown an increasing interest in using event-related potentials (ERPs) to study depression. These studies generally fall into four classes: 1), ERPs as a means of detecting depression; 2), ERPs as a tool for distinguishing subtypes of depression; 3), ERPs as a measure of pharmacological effectiveness; 4), ERPs as indicators of defective cognitive operations in depressed subjects. Results from these heterogeneous approaches are often inconsistent and disappointing. Although some ERP components often show increased latencies and diminished amplitudes, these changes seem to reflect principally a variety of non-specific disorders affecting a wide range of cognitive functions rather than a precise and consistent deficit of a particular function. These disappointing results seem to be attributable to methodological problems (heterogeneous patient populations, disproportionate use of the odd-ball paradigm), and do not necessarily call into question the value of studying the ERPs. Furthermore, recent advances in ERP methodology have opened up new perspectives for ERP use in psychopathology.

Streszczenie:

Two convolution neural network (CNN) models are introduced to accurately classify event-related potentials (ERPs) by fusing frequency, time, and spatial domain information acquired from the continuous wavelet transform (CWT) of the ERPs recorded from multiple spatially distributed channels. The multidomain models fuse the multichannel Z-scalograms and the V-scalograms, which are generated from the standard CWT scalogram by zeroing-out and by discarding the inaccurate artifact coefficients that are outside the cone of influence (COI), respectively. In the first multidomain model, the input to the CNN is generated by fusing the Z-scalograms of the multichannel ERPs into a frequency-time-spatial cuboid. The input to the CNN in the second multidomain model is formed by fusing the frequency-time vectors of the V-scalograms of the multichannel ERPs into a frequency-time-spatial matrix. Experiments are designed to demonstrate (a) customized classification of ERPs, where the multidomain models are trained and tested with the ERPs of individual subjects for brain-computer interface (BCI)-type applications, and (b) group-based ERP classification, where the models are trained on the ERPs from a group of subjects and tested on single subjects not included in the training set for applications such as brain disorder classification. Results show that both multidomain models yield high classification accuracies for single trials and small-average ERPs with a small subset of top-ranked channels, and the multidomain fusion models consistently outperform the best unichannel classifiers.

Online employer review platforms (ERPs) enable employees to evaluate their current and former companies anonymously online. Job-seekers can use the aggregated reviews to obtain information about potentially attractive companies and thus limit the number of suitable companies. However, the matching process between job-seekers and companies can only be effective if the information provided on ERPs is representative and can be trusted. This paper investigates specific characteristics of ERPs using the two large ERPs Kununu and Glassdoor as examples. It is argued that the ERP environment is very different from the well-known and -studied reputation system environment of online marketplaces, and that specific factors can potentially bias reviews on ERPs. Based on a new data set containing the Kununu and Glassdoor reviews of 114 major German employers, it is analyzed if and how design aspects of ERPs and other specific factors affect reviews. Results show that overall (and industry-specific), average review scores on Kununu and Glassdoor differ significantly from each other. Further results indicate that factors such as employees’ awareness of their impact on a company’s reputation also affect reviews. Suggestions are made on how ERPs could reduce the influence of these factors in order to present the aggregated information more effectively.

Intro Electroencephalography (EEG) is a technique for measuring brain activity that is widely used in neuroscience research. Event-related potentials (ERPs) in the EEG make it possible to study sensory and cognitive processes in the brain. Previous reports have shown that aerobic exercise can have an impact on components of ERPs such as amplitude and latency. However, they focused on the measurement of ERPs after exercise. Objectives The aim of this systematic review was to investigate the feasibility of measuring ERPs during cycling, and to assess the impact of cycling on ERPs during cycling. Methods We followed the PRISMA guidelines for new systematic reviews. To be eligible, studies had to include healthy adults and measure ERPs during cycling. All articles were found using Google Scholar and by searching references. Data extracted from the studies included: objectives of ERP studies, ERP paradigm, EEG system, study population data, exercise characteristics (duration, intensity, pedaling cadence), and ERP and behavioral outcomes. The Cochrane Risk of Bias 2 tool was used to assess study bias. Results Twenty studies were selected. The effect of cycling on ERPs was mainly based on a comparison of P3 wave amplitude between cycling and resting states, using an attentional task. The ERP paradigm most often used was the auditory oddball task. Exercise characteristics and study methods varied considerably. Discussion It is possible to measure ERPs during cycling under conditions that are likely to introduce more artifacts, including a 3-h athletic exercise session and cycling outdoors. Secondly, no assessment of the effect of cycling on ERPs was possible, because the methods differed too widely between studies. In addition, the theories proposed to explain the results sometimes seemed to contradict each other. Although most studies reported significant results, the direction of the effects was inconsistent. Finally, we suggest some areas for improvement for future studies on the subject.

Streszczenie:

The recording of brain event-related potentials (ERPs) is a widely used technique to investigate the neural basis of sensory perception and cognitive processing in humans. Due to the low magnitude of ERPs, averaging of several consecutive stimuli is typically employed to enhance the signal to noise ratio (SNR) before subsequent analysis. However, when the temporal interval between two consecutive stimuli is smaller than the latency of the main ERP peaks, i.e., when the stimuli are presented at a fast rate, overlaps between the corresponding ERPs may occur. These overlaps are usually dealt with by assuming that there is a simple additive superposition between the elicited ERPs and consequently performing algebraic waveform subtractions. Here, we test this assumption rigorously by providing a statistical framework that examines the presence of nonlinear additive effects between overlapping ERPs elicited by successive stimuli with short interstimulus intervals (ISIs). The results suggest that there are no nonlinear additive effects due to the time overlap per se but that, for the range of ISIs examined, the second ERP is modulated by the presence of the first stimulus irrespective of whether there is time overlap or not. In other words, two ERPs that overlap in time can still be written as an addition of two ERPs but with the second ERP being different from the first. This difference is also present in the case of nonoverlapping ERPs with short ISIs. The modulation effect elicited on the second ERP by the first stimulus is dependent on the ISI value.

We studied scalp-recorded auditory event-related potentials (ERPs) of 30 untreated patients with new-onset temporal lobe epilepsy and 30 age-and sex-matched normal controls. This study was designed to eliminate the effects of intractability of seizures and chronic use of antiepileptic drugs on P300 auditory ERPs. There were no statistically significant differences in both latency and amplitude of P300 between the two groups. Similar methods were also used to analyze component latencies and amplitudes of ERPs of 9 patients who had hippocampal sclerosis with comparison to control subjects. There were no statistically significant differences between these two groups as well. Our study evidently does not support temporal lobe sources of P300 scalp-recorded auditory ERPs. We also conclude that the scalp-recorded auditory ERPs procedure is not a useful tool to evaluate temporal lobe epilepsy.

Event-related potentials (ERPs) are direct measures of brain activity that can be leveraged for clinically meaningful research. They can relate robustly both to continuous measures of individual difference and to categorical diagnoses in ways that clarify similarities and distinctions between apparently related disorders and traits. ERPs can be linked to genetic risk, can act as moderators of developmental trajectories and responses to stress, and can be leveraged to identify those at greater risk for psychopathology, especially when used in combination with other neural and self-report measures. ERPs can inform models of the development of, and risk for, psychopathology. Finally, ERPs can be used as targets for existing and novel interventions and prevention efforts. We provide concrete examples for each of these possibilities by focusing on programmatic research on the error-related negativity and anxiety, and thus show that ERPs are poised to make greater contributions toward the identification, prediction, treatment, and prevention of mental disorders.

Electric railway power systems (ERPS) as one of the most critical and high-power end-user loads of utility grids are characterized by outlandish power quality (PQ) problems all over the world. The extension and evolution of different supply topologies for these systems has resulted in significant and various forms of distortions in network voltage and current in all ERPS, the connected power system, and adjacent consumers. During the last years, numerous studies have been offered to investigate various aspects of PQs in a specific supplying topology. Variation in the supply structure of the ERPS and different types of locomotives has propelled the observation of different PQ phenomena. This versatility and development have led to confront considerable types of two-way interactive interfaces as well as reliability and PQ problems in ERPS. In addition, the lack of standards explicitly dedicated to ERPS has added to the ambiguity and complexity of this issue. In this paper, an extensive review of PQ distortions and phenomena in different configurations of ERPS is proposed and a systematic classification is presented. More than 140 scientific papers and publications are studied and categorized which can provide a fast review and a perfect perspective on the status of PQ indexes for researchers and experts.

The purpose of this research was to examine whether the Enterprise Resource Planning System (ERPS) usage by Indonesian companies affected the firm performance based on the balanced scorecard approach directly or moderated by strategic alignment. This research also assessed the performance between companies that applied ERPS with Supply Chain Management (SCM) and the companies applying ERPS without SCM. Data collection was conducted from October 2010 to April 2011 using questionnaires sent to respondents by e-mail and directly to the company. The sampling method used was convenience sampling by visiting companies in the survey. The final number of samples were 63 companies. Data analysis was conducted by using Structural Equation Model (SEM). The results show that ERPS usage directly affects firm performance as measured by the balanced scorecard that includes financial perspective, customer perspective, internal process perspective, and learning and growth perspectives. Moreover, the strategic alignment has been proven as a moderating variable in the relationship between ERPS usage and the firm performance. Finally, the modules addition such as SCM significantly affects the firm performance.

O are estimated simultaneously on the assumption that the system of selected standard stations does not rotate. Longitudes and latitudes of the stations are determined every 2 months. Disagreement of the ERPs with those obtained by the space techniques decreased much compared with the published ERPs of the IPMS. It is expected that the ERPs in the whole period are also improved significantly.

Event-related potentials (ERPs) electrophysiological technique has been used for decades as a reliable neurophysiological toolfor the study of sensory, motor, and cognitive processes. This technique captures the brain’s electrical activity signalsynchronized with a particular event, such as the appearance of an auditory stimulus, a written word, or an image. Given thehigh temporal resolution offered by ERPs, it is possible to study rigorously the course and temporal dynamics of the neuralprocesses involved in information processing. Furthermore, ERPs are also reliable neurophysiological markers for thediagnosis of sensitive pathways disorders and are useful in the study of brain function disorders such as injuries,neurodegenerative diseases, and neuropsychiatric disorders such as Parkinson's disease, and schizophrenia. Accordingly, weconsider it relevant to carry out a general review of the theoretical and methodological fundamentals of ERPs.

Streszczenie:

ResumenDurante los 15 últimos años, los investigadores han mostrado un interés cada vez mayor por utilizar los potenciales evocados cognitivos (ERPs) para estudiar la depresión. En general, estos estudios se dividen en cuatro clases: 1) los ERPs como medio de detectar la depresión; 2) los ERPs como herramienta para distinguir subtipos de depresión; 3) los ERPs como medida de la efectividad farmacológica; 4) los ERPs como indicadores de operaciones cognitivas defectuosas en sujetos deprimidos. Los resultados de estos enfoques heterogéneos son a menudo inconsistentes y decepcionantes. Aunque algunos componentes del ERP muestran con frecuencia mayores latencias y menores amplitudes, estos cambios parecen reflejar principalmente una variedad de trastornos no específicos que afectan a un amplio conjunto de funciones cognitivas, más que un déficit preciso y consistente de una función particular. Estos resultados decepcionantes parecen ser atribuibles a problemas metodológicos (poblaciones de pacientes heterogéneos, uso desproporcionado del paradigma de “estímulo atípico” [odd-ball]) y no ponen necesariamente en tela de juicio el valor de estudiar los ERP. Además, recientes avances en la metodología de los ERP han abierto nuevas perspectivas para su uso en psicopatología.

Background. While numerous studies have found disturbances in the Event-Related Potentials (ERPs) of patients with schizophrenia linked to task relevant target stimuli (most notably a reduction in P300 amplitude), few have examined ERPs to task irrelevant non-targets. We hypothesize, from current models of dysfunction in information processing in schizophrenia, that there will be less difference between ERPs to targets and non-targets in patients with schizophrenia than in controls.Methods. EEGs were recorded for 40 subjects with schizophrenia and 40 age and sex matched controls during an auditory oddball reaction time task. ERPs to the targets and non-targets immediately preceding the targets were averaged separately.Results. There was a disturbance in ERPs to targets but also to non-targets (reduced N100 amplitude and earlier P200 latency) and the difference between target and non-target ERP components (N100 and P200 amplitude and P200 latency), was significantly reduced in the schizophrenic group compared with controls.Conclusions. These findings suggest a disturbance in processing task relevant and irrelevant stimuli, consistent with Gray's (1998) hypothesis of misattributions in the ‘match[ratio ]mismatch’ of novel (target) and familiar (non-target) sensory input compared with stored information.

Enterprise Resource Planning Systems (ERPs) are of vital importance to all institutions, especially those involved in higher education (HEIs). However, the level of their implementation among these institutions has shown poor results. Currently, higher education institutions in Malaysia have yet to explore factors leading to the successful implementation of ERPs. There is a lack of research on ERP systems implemented in HEIs, especially regarding their success factors. As such, a literature review was conducted on ERPs in higher education institutions, discussing the advantages of different systems; their obstacles to implementation; and their success factors in HEIs. This review concluded with two theories by which to define the most critical and impactful factors to these systems' success. It is hoped that this review will help HEIs to understand the factors that might lead to the successful implementation of ERPs. In addition, implementing ERPs successfully in higher education will help develop a global competitive advantage, as well as affect the satisfaction levels of stakeholders in HEIs. Whilst investments in ERP systems by modern organisations are becoming increasingly common – especially amongst higher education institutions - the lack of previous empirical research in this environment has neglected the potential benefits of these systems.

Human activities consisting of multiple component actions require the generation of ordered sequences. This study investigated the scope of response planning in highly serial task, typing, by means of ERPs indexing motor response preparation. Specifically, we compared motor-related ERPs yielded by words typed using a single hand against words that had all keystrokes typed with a single hand, except for a deviant one, typed with the opposite hand. The deviant keystroke occurred either early in the typed sequence, corresponding to the second or third letters, or late, corresponding to the penultimate or last letter. Motor-related ERPs detected before response onset were affected only by deviant keystrokes located at the beginning of the sequence, whereas deviant keystrokes located at the end yielded ERPs that were undistinguishable from unimanual responses. These results impose some constraints on the notion of parallel processing of component actions.

The ability to discriminate phonetically similar speech sounds is evident quite early in development. However, inexperienced word learners do not always use this information in processing word meanings [Stager & Werker (1997). Nature, 388, 381–382]. The present study used event-related potentials (ERPs) to examine developmental changes from 14 to 20 months in brain activity important in processing phonetic detail in the context of meaningful words. ERPs were compared to three types of words: words whose meanings were known by the child (e.g., “bear”), nonsense words that differed by an initial phoneme (e.g., “gare”), and nonsense words that differed from the known words by more than one phoneme (e.g., “kobe”). These results supported the behavioral findings suggesting that inexperienced word learners do not use information about phonetic detail when processing word meanings. For the 14-month-olds, ERPs to known words (e.g., “bear”) differed from ERPs to phonetically dissimilar nonsense words (e.g., “kobe”), but did not differ from ERPs to phonetically similar nonsense words (e.g., “gare”), suggesting that known words and similar mispronunciations were processed as the same word. In contrast, for experienced word learners (i.e., 20-month-olds), ERPs to known words (e.g., “bear”) differed from those to both types of nonsense words (“gare” and “kobe”). Changes in the lateral distribution of ERP differences to known and unknown (nonce) words between 14 and 20 months replicated previous findings. The findings suggested that vocabulary development is an important factor in the organization of neural systems linked to processing phonetic detail within the context of word comprehension.

Alpine grassland is sensitive to climate change, and many studies have explored the trends in alpine vegetation. Most research focuses on the effects of climate warming and increased humidity on vegetation greening. However, less attention has been given to the positive impacts of human activities, particularly ecological restoration projects (ERPs). Our study utilized the CASA (Carnegie Ames Stanford Approach) model to simulate the net primary productivity (NPP) of alpine grasslands on the Tibetan Plateau (TP) from 2000 to 2020. Additionally, a moving window approach was employed to comparatively analyze the changes in the response characteristics of NPP to climate change before and after the implementation of ERPs. Our results indicated: (1) The NPP exhibited a fluctuating upward trend. The NPP growth rates of alpine meadow, alpine grassland, and desert grassland were found to be 2.38, 1.5, and 0.8 g C·m−2·a−1, respectively. (2) The annual average NPP and annual growth rate of alpine grasslands after the implementation of ERPs were both higher than before, indicating that ERPs have intensified the growth trend of NPP in alpine grasslands. (3) ERPs have reduced the responsiveness of alpine grassland NPP to temperature variations and enhanced its responsiveness to changes in precipitation. In detail, ERPs enhanced the responsiveness of NPP in alpine meadow to both temperature and precipitation, reduced the responsiveness of NPP in alpine steppe to temperature while enhancing its responsiveness to precipitation, and mitigated the changes in the response of NPP in desert steppe to temperature and significantly enhanced its responsiveness to precipitation.

Abstract In the last decade, many studies have tried to define the neural correlates of attention deficit hyperactivity disorder (ADHD). The main aim of this study is the comparison of the ERPs independent components in the four QEEG subtypes in a group of ADHD adults as a basis for defining the corresponding endophenotypes among ADHD population. Sixty-seven adults diagnosed as ADHD according to the DSM-IV criteria and 50 age-matched control subjects participated in the study. The brain activity of the subjects was recorded by 19 channel quantitative electroencephalography (QEEG) system in two neuropsychological tasks (visual and emotional continuous performance tests). The ICA method was applied for separation of the independent ERPs components. The components were associated with distinct psychological operations, such as engagement operations (P3bP component), comparison (vcomTL and vcom TR), motor inhibition (P3supF) and monitoring (P4monCC) operations. The ERPs results point out that there is disturbance in executive functioning in investigated ADHD group obtained by the significantly lower amplitude and longer latency for the engagement (P3bP), motor inhibition (P3supF) and monitoring (P4monCC) components. Particularly, the QEEG subtype IV was with the most significant ERPs differences comparing to the other subtypes. In particular, the most prominent difference in the ERPs independent components for the QEEG subtype IV in comparison to other three subtypes, rise many questions and becomes the subject for future research. This study aims to advance and facilitate the use of neurophysiological procedures (QEEG and ERPs) in clinical practice as objective measures of ADHD for better assessment, subtyping and treatment of ADHD.

P300 event-related potentials (ERPs), objective measures related to cognitive processing, have not been studied in Sydenham’s chorea (SC) patients. Purpose: To assess cognitive impairment with P300 ERPs. Method: Seventeen patients with SC and 20 unaffected healthy children were included. Stanford–Binet test was used for psychometric assessment, and odd-ball paradigm was used for auditory ERPs. Results: There was no significant difference in P300 latencies between the SC-pretreatment group, SC-posttreatment group and control group (p>0.05). Mean interpeak latencies in SC-pretreatment group and SC-posttreatment group showed significant prolongation compared with the control group (p<0.05). Mean interpeak latencies in SC-posttreatment group were significantly decreased compared with SC-pretreatment group (p<0.05). Compared to controls, patients did not show significant difference in Stanford-Binet intelligence examination. Conclusion: This report suggests that interpeak latencies and amplitudes of P300 ERPs could be useful for detecting and monitoring cognitive impairment in SC patients.

Objective: Enhanced Recovery Protocols (ERPs) have been shown in many different settings to lead to quicker recovery for most patients, with a significantly reduced average length of post-operative stay (LOS). A less studied impact of ERPs has been their effect on hospital profitability. While these protocols are resource-intensive and expensive to implement, we argue that they can lead to significantly improved margins. This can be attributed to fewer complications and, more significantly, reductions in LOS resulting in increased patient capacity.Methods: Our ERP was implemented in June of 2014. The protocol was initially used only for colo-rectal cases, both elective and emergent. It contained over 20 pre-, intra-, and post-operative elements of surgical care. One year of data from the ERP cases was compared to contemporaneous controls that did not go through the ERP. Financial data was obtained from the hospital cost accountant. Average LOS was obtained from the EHR.Results: Patients who underwent colo-rectal procedures and participated in the ERP had an average LOS of 5.60 days, while controls stayed for an average of 8.51 days. Financial analysis determined that a full year of compliance with Enhanced Recovery After Surgery (ERAS) protocols added over 2 million dollars to the margin for a return on investment (ROI) of over 10 to 1, mainly by increasing hospital capacity and allowing more admissions.Conclusions: The results demonstrate that ERPs significantly reduce LOS, increasing hospital patient capacity. The higher patient load more than recoups ERP costs. Further collection and analysis of data aims to determine the effect on complications, which also have cost saving potential.

Literacy is a complex and multidimensional phenomenon that has been well studied in psychology and pedagogy. Neurophysiologists try to understand the mechanisms of writing and reading acquisition by analyzing different linguistic processes. In this paper, we review the data that were revealed by using the event-related potentials (ERPs) method in the light of spelling, lexical, semantic and syntactic aspects of literacy, as well as changes in the components of ERPs in children and adults during language acquisition and in dyslexia, the most studied reading disorder. The ERPs method can help to understand both the general, universal neural underpinnings of literacy development and the unique features of different languages.

Mental rotation is an important psychological process for identifying rotated or misoriented objects. In this study, ERPs were recorded while 18 participants responded to two types of two-dimensional (2D) pictures. The participants matched the pictures of a blank Task without using mental rotation, but used mental rotation to match the pictures of Task A. The ERPs data were analyzed using spatial complexity analysis. The results showed: a) the rotation-related negativity of the ERPs data was shown when mental rotation was performed; b) the EEG data showed a significantly greater synchronization in the fast frequency bands (> 20 Hz) when the participants used their mental rotation ability.

Event-related brain potentials (ERPs) to words, pseudowords, and nonwords were recorded in three different tasks. A letter search task was used in Experiment 1. Performance was affected by whether the target letter occurred in a word, a pseudoword, or a random nonword. ERP results corroborated the behavioral results, showing small but reliable ERP differences between the three stimulus types. Words and pseudowords differed from nonwords at posterior sites, whereas words differed from pseudowords and nonwords at anterior sites. Since deciding whether the target letter was present or absent co-occurred with stimulus processing in Experiment 1, a delayed letter search task was used in Experiment 2. ERPs to words and pseudowords were similar and differed from ERPs to nonwords, suggesting a primary role of orthographic and phonological processing in the delayed letter search task. To increase semantic processing, a categorization task was used in Experiment 3. Early differences between ERPs to words and pseudowords at left posterior and anterior locations suggested a rapid activation of lexico-semantic information. These findings suggest that the use of ERPs in a multiple task design makes it possible to track the time course and the activation of multiple sources of linguistic information when processing words, pseudowords, and nonwords. The task-dependent nature of the effects suggests that the language system can use multiple sources of linguistic information in flexible and adaptive ways.

Although biases toward signals of fear may be an evolutionary adaptation necessary for survival, heightened biases may be maladaptive and associated with anxiety or depression. In this study, event-related potentials (ERPs) were used to examine the time course of neural responses to facial fear stimuli (versus neutral) presented overtly (for 500 msec with conscious attention) and covertly (for 10 msec with immediate masking to preclude conscious awareness) in 257 nonclinical subjects. We also examined the impact of trait anxiety and depression, assessed using psychometric ratings, on the time course of ERPs. In the total subject group, controlled biases to overtly processed fear were reflected in an enhancement of ERPs associated with structural encoding (120–220 msec) and sustained evaluation persisting from 250 msec and beyond, following a temporo-occipital to frontal topography. By contrast, covert fear processing elicited automatic biases, reflected in an enhancement of ERPs prior to structural encoding (80–180 msec) and again in the period associated with automatic orienting and emotion encoding (230–330 msec), which followed the reverse frontal to temporo-occipital topography. Higher levels of trait anxiety (in the clinical range) were distinguished by a heightened bias to covert fear (speeding of early ERPs), compared to higher depression which was associated with an opposing bias to overt fear (slowing of later ERPs). Anxiety also heightened early responses to covert fear, and depression to overt fear, with subsequent deficits in emotion encoding in each case. These findings are consistent with neural biases to signals of fear which operate automatically and during controlled processing, feasibly supported by parallel networks. Heightened automatic biases in anxiety may contribute to a cycle of hypervigilance and anxious thoughts, whereas depression may represent a “burnt out” emotional state in which evaluation of fear stimuli is prolonged only when conscious attention is allocated.

Streszczenie:

EEG (electroencephalography), as a noninvasive and inexpensive method, is widely used to measure brain function and make inferences about regional brain activity. The stationarity of EEG has been investigated by many researchers, while the stationarity of EEG segment with ERPs (Event-related Potentials) has hardly been concerned about. It is necessary to analyze the stationarity of this kind of EEG. In this paper, we concentrate on the stationarity of the EEG with ERPs by testing the stationarity of 500ms EEG segments with ERPs recorded from six subjects in two types of experiments. The results suggest that selected EEG segment whose length is larger than 190ms remains to be stationarity and all epochs duration less than 40ms is considered to be stationary, whichever channel the data is from and whatever type of cognitive task is performed in the experiment. This is an obvious difference between the stationarity of EEG with ERPs and that of EEG, which is reported to be stationary as long as its length is less than 12s.
