Neurofeedback Outcomes in Clients with Asperger's Syndrome.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This paper summarizes data from a review of neurofeedback (NFB) training with 150 clients with Asperger's Syndrome (AS) and 9 clients with Autistic Spectrum Disorder (ASD) seen over a 15 year period (1993-2008) in a clinical setting. The main objective was to investigate whether electroncephalographic (EEG) biofeedback, also called neurofeedback (NFB), made a significant difference in clients diagnosed with AS. An earlier paper (Thompson et al. 2009) reviews the symptoms of AS, highlights research findings and theories concerning this disorder, discusses QEEG patterns in AS (both single and 19-channel), and details a h...

Evaluating the Interplay Between Spirituality, Personality and Stress.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Spirituality and the big five personality traits may be risk or protective factors for coping with stress. We hypothesized young adults who reported higher spirituality ratings would demonstrate lower sympathetic nervous system arousal and better emotional coping when exposed to a laboratory stressor compared to those who rated themselves lower in spirituality. We also compared spirituality groups on trait anger, neuroticism, conscientiousness, extraversion, agreeableness and openness to experience. Eighty participants completed trait-state anger, personality and spirituality questionnaires and were grouped into low, a...

Electrical Concepts in the Surface Electromyographic Signal.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
There are frequently used electrical terms in the biofeedback literature. Often it is assumed that the reader has detailed knowledge of these terms. The difficulty begins when seemingly familiar terms are used as a basis for an in-depth explanation of the process of electromyography. For example, the concept of impedance is based on three building blocks of electricity: current, voltage and resistance. The term "impedance" is found in every manual for biofeedback equipment with the suggestion that the electrode site be kept "low" and the encoder input "high". A little electrical knowledge can explain why this is so and...

Heart Rate Variability During Sleep Following the Practice of Cyclic Meditation and Supine Rest.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Day time activities are known to influence the sleep on the following night. Cyclic meditation (CM) has recurring cycles. Previously, the low frequency (LF) power and the ratio between low frequency and high frequency (LF/HF ratio) of the heart rate variability (HRV) decreased during and after CM but not after a comparable period of supine rest (SR). In the present study, on thirty male volunteers, CM was practiced twice in the day and after this the HRV was recorded (1) while awake and (2) during 6 h of sleep (based on EEG, EMG and EGG recordings). This was similarly recorded for the night's sleep following the day ti...

Recent Advances in Quantitative EEG as an Aid to Diagnosis and as a Guide to Neurofeedback Training for Cortical Hypofunctions, Hyperfunctions, Disconnections, and Hyperconnections: Improving Efficacy in Complicated Neurological and Psychological Disorders.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Recent advances in QEEG-databases have enabled improvements in interpretation, which in turn have led to more effective neurofeedback interventions. These improvements relate mostly to evaluations conducted in the high frequency beta range (21-30 Hz) evaluation and in single Hz bins, which more specifically address which frequencies need to be trained to most quickly and effectively normalize their dysfunctions and remediate their difficulties. Use of the modular activation/coherence model (Walker et al. in J Neurother 11: 25-44, 2007) provides a framework for correcting the slow or fast modular dysfunctions, as well a...

An Exploratory Study on the Effects of Tele-neurofeedback and Tele-biofeedback on Objective and Subjective Sleep in Patients with Primary Insomnia.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Insomnia is a sleeping disorder, usually studied from a behavioural perspective, with a focus on somatic and cognitive arousal. Recent studies have suggested that an impairment of information processes due to the presence of cortical hyperarousal might interfere with normal sleep onset and/or consolidation. As such, a treatment modality focussing on CNS arousal, and thus influencing information processing, might be of interest. Seventien insomnia patients were randomly assigned to either a tele-neurofeedback (n = 9) or an electromyography tele-biofeedback (n = 8) protocol. Twelve healthy controls were used to compare b...

Monitoring Cognitive and Emotional Processes Through Pupil and Cardiac Response During Dynamic Versus Logical Task.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The paper deals with the links between physiological measurements and cognitive and emotional functioning. As long as the operator is a key agent in charge of complex systems, the definition of metrics able to predict his performance is a great challenge. The measurement of the physiological state is a very promising way but a very acute comprehension is required; in particular few studies compare autonomous nervous system reactivity according to specific cognitive processes during task performance and task related psychological stress is often ignored. We compared physiological parameters recorded on 24 healthy subjec...

Heart Rate Recovery Predicts Memory Performance in Older Adults.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The current study examined cardiovascular reactivity and recovery during memory testing in a sample of 28 younger and 28 older adults. Heart rate (HR) levels were measured before, during, and after a memory test (word list recall). Contrary to prediction, older adults did not have a blunted cardiovascular response to memory tasks compared to younger adults. Word list recall performance was predicted by both Age and an Age x HR recovery interaction. As expected, younger adults performed better on the word list task than older adults. In addition, older adults with better posttest HR recovery performed significantly bett...

The Need for Individualization in Neurofeedback: Heterogeneity in QEEG Patterns Associated with Diagnoses and Symptoms.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Very diverse assessment procedures are utilized by neurofeedback practitioners, many of which are not based on careful examination of raw EEG data followed by scientifically objective quantitative EEG (QEEG) database comparisons. Research is reviewed demonstrating the great heterogeneity in the EEG patterns associated with various diagnoses and symptoms. The fact that most patients qualify for dual diagnoses, with co-morbid psychiatric and medical conditions present, complicates the ability of clinicians to estimate what electrophysiological patterns may be associated with symptoms. In such cases treatment planning is ...

We investigated the potential impact of abuse history on autonomic regulation and psychological wellbeing in a sample of women who reported a history of abuse without Post Traumatic Stress Disorder. To measure autonomic regulation, heart rate data was collected before and after the participant rode a stationary bike for one mile. We found that abuse history was associated with less vagal regulation of the heart (i.e., respiratory sinus arrhythmia) and an inability to rapidly re-engage vagal regulation immediately following mild exercise to support a calm physiological state. These findings are consistent with clinical ...

The Concealed Information Test as an Instrument of Applied Differential Psychophysiology: Methodological Considerations.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this interpretative paper, I consider four sets of methodological issues that may be relevant to improving the concealed information test (CIT) as an instrument of applied differential psychophysiology. The first set has to do with psychophysiological measurement in the CIT (e.g., specific sensitivity testing in lab vs. field). Secondly, I consider the relationships between the psychological process of deception and the CIT. Thirdly, I consider the problem of laboratory-to-field generalization of the CIT, a consideration that includes a discussion of whether the lab/field differences are merely quantitative or actua...

Information Gain of Psychophysiological Detection of Deception in Forensic and Screening Settings.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We adapted and applied the Wells and Olson's (2002) Information Gain Analyses to examine the relative usefulness of a common psycho-physiological deception detection (PDD) technique, the Comparison Question Test, in forensic and screening settings as compared to unassisted lay and professional persons. We found that in forensic settings PDD provided substantial improvements in information gain over unassisted laypersons across nearly the complete range of the base rate of guilt. This was true for accuracy estimates based on laboratory and field data. At p(guilt) = 0.9, a benchmark set by critics of PDD, PDD provided 27...

In the second experiment, participants were presented with autobiographical information, alternated with irrelevant stimuli, while instructed to respond based on the case of the stimuli. Results showed that with both familiar faces, and autobiographical informa...

Detecting Concealed Knowledge Using a Novel Attentional Blink Paradigm.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Traditional concealed information paradigms rely on the idea that stimuli that are meaningful to a person (critical items) will draw attentional resources disproportionately, relative to stimuli that are not (irrelevant items), generating detectable differences on a suitable dependent variable (behavioral, psychophysiological, or neural). Here, we introduce a behavioral paradigm that could be used to reveal concealed information by exploiting the link between concealed information and attentional processes more directly. This novel paradigm is based on the attentional blink phenomenon in which detection of a stimulus r...

Assigned Versus Random, Countermeasure-Like Responses in the P300 Based Complex Trial Protocol for Detection of Deception: Task Demand Effects.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We recently introduced an accurate and countermeasure resistant P300-based deception detection test called the complex trial protocol (Rosenfeld et al. in Psychophysiology 45(6):906-919, 2008). When subjects use countermeasures to all irrelevant items in the test, the probe P300 is increased rather than reduced (as it was in previous P300-based deception protocols), allowing detection of countermeasure users. The current experiment examines the role of task demand on the complex trial protocol by forcing the subject to make countermeasure-like response to stimuli. Subjects made either a simple random button response to...

The effects of physical and mental countermeasures on the accuracy of the concealed information test (CIT) were examined in a mock crime experiment with 64 participants. To combat countermeasures, two covert respiration measures, hidden in the seat and back of the examination chair, were used in addition to the standard physiological measures (SCR, FPWL, RLL). Some guilty participants were trained to use either physical or mental countermeasures and apply them to distort the outcomes of the CIT. In the second phase of the experiment participants were detached from the standard polygraph devices and examined solely with...

Time and Encoding Effects in the Concealed Knowledge Test.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Although the traditional "lie detector" test is used frequently in forensic contexts, it has (like most test of deception) some limitations. The concealed knowledge test (CKT) focuses on participants' recognition of privileged knowledge rather than lying per-se and has been studied extensively using a variety of measures. A "guilty" suspect's interaction with and memory of crimescene items may vary. Furthermore, memory for crimescene items may diminish over time. The interaction of encoding quality and test delay on CKT efficiency has been previously implied, but not yet demonstrated. We used a response-time based CKT ...

Differentiating Orienting and Defensive Responses to Concealed Information: The Role of Verbalization.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Using physiological measures, concealed information can be validly assessed. Orienting theory has been proposed to account for concealed information testing. As orienting is characterized by heart rate deceleration, one would expect this type of heart rate response to concealed information. However, with some exceptions, an initial heart rate acceleration to concealed information is typically observed. In the present paper, we examine the role of verbalization to explain the mixed pattern of heart rate changes. Using a within-subjects design, 30 participants were asked to either remain silent or to give an overt verbal...

EEG and SCR were recorded during a five task assessment session, including: (1) pre-baseline, (2) eyes open at rest, (3) eyes closed at rest, (4) sensory attentiveness (listening to an audio book clip), and (5) cognitive effort (a higher level cognitive flexibility task). A...

Psychophysiological Profile in Dyssynergic Defecation Patients: An Individual and Situational Response Specificity Analysis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The aim of this study was to evaluate the temporal stability and the situational specificity of the intra-anal EMG-activity, as well as the individual specificity of this response in dyssynergic defecation patients. With this purpose, 26 individuals (13 with dyssynergic defecation and 13 without anorectal pathology) participated in two sessions of psychophysiological assessment, with an inter-session period of 1 week. At each session, the EMG-activity of external anal sphincter was recorded under four different conditions (baseline, voluntary contraction, reflex contraction and simulated defecation). The findings provi...

The Effect of Biofeedback on Function in Patients with Heart Failure.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Decreased HRV has been consistently associated with increased cardiac mortality and morbidity in HF patients. The aim of this study is to determine if a 6-week course of heart rate variability (HRV) biofeedback and breathing retraining could increase exercise tolerance, HRV, and quality of life in patients with New York Heart Association Class I-III heart failure (HF). Participants (N = 29) were randomly assigned to either the treatment group consisting of six sessions of breathing retraining, HRV biofeedback and daily practice, or the comparison group consisting of six sessions of quasi-false alpha-theta biofeedback a...

Psychophysiological Patterns During Cell Phone Text Messaging: A Preliminary Study.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study investigated the psychohysiological patterns associated with cell phone text messaging (texting). Twelve college students who were very familiar with texting were monitored with surface electromyography (SEMG) from the shoulder (upper trapezius) and thumb (abductor pollicis brevis/opponens pollicis); blood volume pulse (BVP) from the middle finger, temperature from the index finger, and skin conductance (SC) from the palm of the non-texting hand; and respiration from the thorax and abdomen. The counter-balanced procedure consisted of a 2 min pre-baseline, 1 min receiving text messages, 2 min middle baseline, 1 m...

Cardiovascular Response to Interpersonal Provocation and Mental Arithmetic among High and Low Hostile Young Adult Males.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
To examine the relation between hostility and cardiovascular reactivity to stress, 42 undergraduate men were categorized into high and low hostile groups based on responses to the Cook Medley Hostility Scale. Participants engaged in two laboratory tasks: a Cognitive Task (mental arithmetic) and a Social Task (confrontation role-play). Cardiovascular measures of heart rate and blood pressure were obtained throughout rest and task periods and participants provided ratings of state anger and forgiveness following task completion. Results revealed that low hostile participants exhibited greater systolic blood pressure (SBP...

Traumatic Brain Injury Rehabilitation: QEEG Biofeedback Treatment Protocols.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Interventions for improvement of cognitive problems in patients with traumatic brain injury (TBI) include electroencephalography biofeedback, also known as neurofeedback. Quantitative electroencephalography (QEEG) patterns are assessed in TBI patients and then compared to a database obtained from a normative population. Deviations in QEEG patterns from the normative group are the basis for an intervention plan. While QEEG patterns, obtained under an eyes closed, resting condition, provide information about deviations at rest, QEEG patterns obtained while the patient engages in cognitive tasks reflect specific deficienc...

Event-related Potential Study of Novelty Processing Abnormalities in Autism.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
To better understand visual processing abnormalities in autism we studied the attention orienting related frontal event potentials (ERP) and the sustained attention related centro-parietal ERPs in a three stimulus oddball experiment. The three stimulus oddball paradigm was aimed to test the hypothesis that individuals with autism abnormally orient their attention to novel distracters as compared to controls. A dense-array 128 channel EGI electroencephalographic (EEG) system was used on 11 high-functioning children and young adults with autism spectrum disorder (ASD) and 11 age-matched, typically developing control subj...

Effects of Inspiratory Strength Training on the Detection of Inspiratory Loads.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Pressure-threshold loads (DeltaPT) are inspiratory force-related loads, which contrast with resistive loads (DeltaR), are airflow-dependent loads. If detection of respiratory loads is a function of the background load, then pressure-threshold type inspiratory muscle strength training (IMST) would affect the detection of DeltaPT but have less effect on detection of DeltaR. DeltaR and DeltaPT detection and ventilatory responses were measured in healthy volunteers. IMST consisted of 4 sets of 6 breaths per day for 4 weeks, at 75% of maximal inspiratory pressure (MIP). MIP increased and a measure of inspiratory dirve, the ...

Rhythmic Oscillations in Quantitative EEG Measured During a Continuous Performance Task.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective of the present investigation was to determine if cyclic variations in human performance recorded during a 30 min continuous performance task would parallel cyclic variations in right-hemisphere beta-wave activity. A fast fourier transformation was performed on the quantitative electroencephalogram (qEEG) and the performance record of each participant (N = 62), producing an individual periodogram for each outcome measure. An average periodogram was then produced for both qEEG and performance by combining (averaging) the amplitudes associated with each periodicity in the 62 original periodograms. Periodicities ...

Changes in pCO(2), Symptoms, and Lung Function of Asthma Patients During Capnometry-assisted Breathing Training.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In a recent pilot study with asthma patients we demonstrated beneficial outcomes of a breathing training using capnometry biofeedback and paced breathing assistance to increase pCO(2) levels and reduce hyperventilation. Here we explored the time course changes in pCO(2), respiration rate, symptoms and lung function across treatment weeks, in order to determine how long training needs to continue. We analyzed in eight asthma patients whether gains in pCO(2) and reductions in respiration rate achieved in home exercises with paced breathing tapes followed a linear trend across the 4-week treatment period. We also explored...
