With the advent of brain computer interfaces based on real-time fMRI rtfMRI-BCIthe possibility of performing neurofeedback based on brain hemodynamics has become a reality, biological psychology research papers. In the early stage of the development of this field, studies In the early stage of the development of this field, studies have focused on the volitional control of activity in circumscribed brain regions. However, based on the understanding that the brain functions by coordinated activity of spatially distributed regions, there have recently been further developments to incorporate real-time feedback of functional connectivity and spatio-temporal patterns of brain activity.
The present article reviews the principles of rtfMRI neurofeedback, its applications, benefits and limitations. A special emphasis is given to the discussion of novel developments that have enabled the use of this methodology to achieve self-regulation of the functional connectivity between different brain areas and of distributed brain networks, anticipating new and exciting applications for cognitive neuroscience and for the potential alleviation of neuropsychiatric disorders.
The role of working memory capacity in cardiovascular monitoring of cognitive workload. The orienting response and information processing within an anticipated paradigm.
Preventing distraction: Assessing stimulus-specific and general effects of the predictive cueing of deviant auditory events. Effects of lateralized cues on the processing of lateralized auditory stimuli. We examined the influence of auditory spatial cues on the processing of subsequently presented lateralized auditory target stimuli. In three experiments, effects of the position of the cue on event-related potentials ERPs and reaction In three experiments, effects of the position of the cue on event-related potentials ERPs and reaction times RTs to the target, which could occur at the same or at a different position to the biological psychology research papers, were examined.
In Experiments I and II, stimulus-pairs were delivered via loudspeakers 13 degrees to the right or left of fixation. The cue was task-irrelevant in the sense that it never required a response, whereas the target was task-relevant. In Experiment I, the cue was not informative about the position of the succeeding target, that is, the target was presented at the same or at a different position to the cue with equal probability.
In Experiment II, the cue predicted a target with high validity, occurring at the position opposite to the cue. In both experiments, the ERPs to targets presented at the same position as the preceding cue were negatively modulated compared with the ERPs to targets presented at a different position. This negative difference Nd between the ERPs to same and different position stimuli occurring between ms relative to target onset was also obtained in situations where no overt behavior was required.
Effects of cue position on RTs to the target were only observed in Experiment II, being shorter for validly predicted targets. These Nd effects either reflect refractoriness of location-specific exogeneous ERP components or involuntary attentional selection. In order to decide between these alternatives, a third experiment was performed, in which stimulus-pairs were presented via headphones to the left and right ear in attend and ignore condition.
An Nd effect was obtained in the attend condition only, biological psychology research papers. The absence of Nd effects in the ignore condition suggests that the Nd obtained in attend condition cannot completely be explained by refractoriness of exogeneous ERP components and thus reflects attentional processes.

Domestic violence and vagal biological psychology research papers to peer provocation. Neurophysiological correlates of error monitoring and inhibitory processing in juvenile violent offenders. Performance monitoring is crucial for well-adapted behavior. Offenders typically have a pervasive repetition of harmful-impulsive behaviors, despite an awareness of the negative consequences of their actions.
However, the link between However, the link between performance monitoring and aggressive behavior in juvenile offenders has not been closely investigated.
Event-related brain potentials ERPs were biological psychology research papers to investigate performance monitoring in juvenile non-psychopathic violent offenders compared biological psychology research papers a well-matched control group. Two ERP components associated with error monitoring, error-related negativity ERN and error-positivity Peand two components related to inhibitory processing, the stop-N2 and stop-P3 components, biological psychology research papers, were evaluated using a combined flanker-stop-signal task.
The results showed that the amplitudes of the ERN, the stop-N2, the stop-P3, and the standard P3 components were clearly reduced in the offenders group. Remarkably, biological psychology research papers, no differences were observed for the Pe. At the behavioral level, slower stop-signal reaction times were identified for offenders, which indicated diminished inhibitory processing.
Specifically, we determined that different aspects of executive function were affected in the studied offenders, including error processing reduced ERN and response inhibition reduced N2 and P3. However, error awareness and compensatory post-error adjustment processes error correction were unaffected. The current pattern of results highlights the role of performance monitoring in the acquisition and maintenance of externalizing harmful behavior that is frequently observed in juvenile offenders.
Specific coping strategies of Africans during urbanization: Comparing cardiovascular responses and perception of health data.
Specific coping mechanisms of Africans during urbanization were compared to and correlated with cardiovascular responses and perception of health data. The COPE questionnaire classified The COPE questionnaire classified subjects as active AC or passive PC copers and the General Health Questionnaire measured subjective perception of health.
The Finapres recorded blood pressure continuously before and during application of a handgrip test. Analyses adjusting for age, body mass index and resting cardiovascular data revealed that AC rural subjects showed predominantly cardiac responses and PC rural subjects predominantly vascular responses, biological psychology research papers. All urbanized African men and women showed higher resting blood pressure, vascular responsiveness and hypertension prevalences than their rural counterparts.
All rural AC subjects, especially women, and all urban PC subjects, especially men, reported a poorer perception of health. In conclusion, subjects with a PC style showed a predominantly vascular response in rural and urban areas whereas subjects with an AC style seem to shift from a predominant cardiac output response to a predominant vascular resistance response when moving from a rural to an urban area.
ERPs differentiate the sensitivity to statistical probabilities and the learning of sequential structures during procedural learning. Procedural learning facilitates the efficient processing of complex environmental stimuli and contributes to the acquisition of automatic behaviors. Although earlier findings suggest different temporal trajectories of the multiple Although earlier findings suggest different temporal trajectories of the multiple learning processes within procedural learning, biological psychology research papers, this has not been clarified at the level of neurocognitive correlates.
Therefore, we investigated whether two prominent learning processes - statistical learning and biological psychology research papers learning - can be distinguished using event-related brain potentials ERPs within the same experimental setting. Both RT and N2 effects reflected the rapid acquisition of statistical probabilities. At the same time, these effects reflected the gradual learning of sequential structures.
The amplitude change of the P3 reflected only gradual sequence learning.

Salivary alpha-amylase response to acute psychosocial stress: The impact of age. Recent evidence A behavioral disassociation was found - compared to CT, ET showed more difficulty in inhibiting surrounding stimuli but had less day-to-day inhibitory issues measured by BRIEF.
There was no significant group difference on response inhibition, biological psychology research papers. Elevated TBR may be an inhibitory biomarker; further studies are needed to explore the behavioral implications in patients without elevated TBR.
Real-Time Adaptive Automation System Based on Identification of Operator Functional State in Simulated Process Control Operations. Behavioural and electrodermal measures of lateralization for music perception in musicians and nonmusicians.
Two groups of students, musicians and nonmusicians were tested on a dichotic listening forced choice recognition task with concurrent recording of bilateral electrodermal activity.
Stimuli were excerpts of Bach 4-part chorales; probes Stimuli were excerpts of Bach 4-part chorales; probes were the soprano, bass, harmony or the chorale excerpt, biological psychology research papers or without changed notes. Laterality effects in recognition and the GSR were obtained only in musicians as a function of the complexity of the task. It was concluded that styles of information processing assumed by the hemispheres are the consequence of an interaction between the stimulus and the state of the organism at the moment, such that the direction of laterality can change within a subject performing the same task depending upon its perceptual demand.
Biosocial models of deviant behavior among male army veterans. Measures of hormones testosterone, cortisol and thyroxin and of deviant or antisocial behavior are examined in a sample of Vietnam veterans. Biosocial models, combining hormonal variables with social background variables, tended to explain more variance in deviance than did traditional models based on social background alone.
Several propositions regarding hormones and behavior were assessed. While the role of hormones in causing deviance remains unclear, it is argued that hormones should be included in models of deviant behavior. Related Topics.
