Gender word semantic satiation inhibits facial gender information processing: Evidence from behavior and event-related potentials.
This study shows that facial gender information processing is affected by its semantic contextual information. The inhibition effect of gender word semantic satiation on facial gender information processing starts at the attention orientation stage, then continues to the face structural encoding stage, and eventually ends at the advanced cognitive response stage.

“Look at me” – Eye movements during autobiographical retrieval in face-to-face interactions.
There has been a surge in social cognition and social neurosciences research comparing laboratory and real eye movements. Eye movements during the retrieval of autobiographical memories (i.e., personal memories) in laboratory situations are also receiving more attention. We compared eye movements during the retrieval of autobiographical memories using a strict laboratory design versus a design mimicking social interactions. In the first design, eye movements were recorded during autobiographical memory retrieval while participants were looking at a blank screen; in the second design, participants wore eye-tracking glasses ...

A preliminary investigation of ERP components of attentional bias in anxious adults using temporospatial principal component analysis.
Threat-related attention bias is thought to contribute to the development and maintenance of anxiety disorders. Dot-probe studies using event-related potentials (ERPs) have indicated that several early ERP components are modulated by threatening and emotional stimuli in anxious populations, suggesting enhanced allocation of attention to threat and emotion at earlier stages of processing. However, ERP components selected for examination and analysis in these studies vary widely and remain inconsistent. The present study used temporospatial principal component analysis (PCA) to systematically identify ERP components elicited...

Feel thine own self—Mood congruency evaluation of emotional state adjectives: An ERP study.
The goal of the study was to explore event-related potential (ERP) differences during the processing of emotional adjectives that were evaluated as congruent or incongruent with the current mood. We hypothesized that the first effects of congruence evaluation would be evidenced during the earliest stages of semantic analysis. Sixty mood adjectives were presented separately for 1,000 ms each during two sessions of mood induction. After each presentation, participants evaluated to what extent the word described their mood. The results pointed to incongruence marking of adjective’s meaning with current mood during early att...

Pupil constrictions and their associations with increased negative affect during responses to recalled memories of interpersonal stress.
Pupil diameter change is indicative of emotional processing. Most previous findings regarding pupillary response and emotion have reported that the pupil enlarges in response to the presentation of emotional perceptual stimuli (e.g., visual images) within several seconds. It is considered that such stimuli activate the sympathetic nervous system, leading to pupil dilation. In order to examine the effects of emotions similar to daily emotional experiences of mood, the present study examined pupil diameter changes and their relationships with subjective emotional changes while recalling a topic of stressful interpersonal eve...

Evidence for altered neural processing in patients with borderline personality disorder: A review of event-related potential studies.
Borderline personality disorder (BPD) is characterized by difficulties in emotion regulation, self-identity disturbances, self-injurious behavior, and reduced inhibitory control. Event-related potential (ERP) studies have sought to reveal the neural correlates of cognitive distortions and behavioral alterations in BPD. The article presents an overview of the existing ERP literature pertaining to BPD and discusses whether any one of the electrophysiological findings could serve as a reliable and specific marker for BPD. In short, ERP studies investigating P300 tentatively suggest impaired inhibitory control. Moreover, reduc...

Cardiovascular responses to stress utilizing anticipatory singing tasks.
This study examines the viability of an anticipatory sing-a-song task as a method for inducing mental stress and examines the utility of the task with specific reference to measures of cardiovascular reactivity and recovery activity, and standard protocols to examine HRV reactivity and recovery. Participants completed a dual task with a math task and an anticipation of singing component. Responses were examined according to a resting/reactivity/recovery paradigm and the findings indicate that the sing-a-song stimulus is effective in generating a stress response. Significant differences in heart rate and self-reported stres...

A psychophysiological examination of the mutability of type D personality in a therapeutic trial.
Identifying the associations between health and personality has been a focus for psychophysiological research. Type D personality is associated with predisposition to physical and psychological ill-health. This statistician-blind parallel-group controlled trial (intervention group vs. waiting list control group) examined the impact of Havening Techniques on the Type D constituents of negative affect (NA) and social inhibition (SI). One hundred twenty-five adult (18+ years) participants in the United Kingdom (72 females, 53 males) completed the Type D Scale-14 (DS14) measure of Type D personality at baseline (T1), 24-hours ...

Respiratory sinus arrhythmia correlates with depressive symptoms following mild traumatic brain injury.
In this study, we investigated if these patterns were observed throughout the typical timeframe of sub-acute mTBI recovery. Although RSA did not differ between mTBI (n = 50) and control (n = 27) groups, depressive symptoms were reliably correlated with RSA only in the mTBI group. This pattern was consistent 2 weeks, 2 months, and 4 months post-injury. Furthermore, resting RSA shortly following injury predicted the trajectory of depressive symptoms 2 months later. These findings generalize the connection between RSA and depression to a clinical population where depressive symptoms are common but often difficult to parse fro...

Circadian rhythms, sleep, and aging.
Circadian mechanisms and the sleep-wakefulness rhythms guarantee survival, adaptation, efficient action in everyday life or in emergencies and well-being. Disordered circadian processes at central and/or cellular levels, sleep disorders, and unhealthy wakefulness/sleep rhythms can impair the physiological circadian organization and result in subjective, professional, or behavioral changes ranging from functional inadequacy to higher risks at work or on the road to medical relevance. Circadian rhythms and the sleep organization change ontogenetically; major changes result from normal aging and from the multiple diseases tha...

Intraocular pressure reactivity to social stressors: The role of self-efficacy, perceived threat, and aversiveness of non-contact tonometry.
A field study was carried out in an optometry clinic, aimed at assessing the role of perceived control and aversiveness of non-contact tonometry in intraocular pressure (IOP) reactivity to psychosocial stressors, and analyzing the covariation with cardiovascular and affective reactivity. Forty-four customers volunteered to participate in the study. Perceived control (self-efficacy and threat) was assessed at the onset. IOP, systolic and diastolic blood pressure, heart rate, affect, and aversiveness of the IOP measurement procedure were assessed throughout five phases with a mean duration for each phase of 9 min: arrival, o...

Unraveling the electrophysiological activity behind recognition memory: An exploratory event related potential (ERP) study.
Traditionally, most event related potential (ERP) studies of memory retrieval have been reported during item-recognition tasks. Those studies lead to two well-known ERP memory components termed FN400 (familiarity) and LPC (recollection). Nevertheless, some critics have raised concerns regarding the actual meaning of that activity since it emerges as the result of contrasting two different memory traces (previously studied vs. seen for the first time), and it is registered after the target presentation. Therefore, they possibly depict operations not related to memory itself but some cognitive processes associated with recog...

Error processing during the online retrieval of probabilistic sequence knowledge.
Adaptive behavior involves rapid error processing and action evaluation. However, it has not been clarified how errors contribute to automatic behaviors that can be retrieved to successfully adapt to our complex environment. Automatic behaviors strongly rely on the process of probabilistic sequence learning and memory. Therefore, the present study investigated error processing during the online retrieval of probabilistic sequence knowledge. Twenty-four healthy young adults acquired and continuously retrieved a repeating stimulus sequence reflected by reaction time (RT) changes on a rapid forced-choice RT task. Performance ...

Induced positive affect reduces the magnitude of the startle response and prepulse inhibition.
The startle response is a reflex that represents a form of adaptation to environmental changes potentially relevant to survival. Startle magnitude can change depending on a number of factors such as the affective state of the organism during the presentation of the startle-inducing stimulus, or the so-called Prepulse Inhibition (PPI) that occurs when the startling stimulus (or Pulse) is preceded by a low-intensity stimulus (or Prepulse). This paper describes an experiment designed to analyze the impact of an induced positive affect on the magnitude of the startle response and PPI in adult humans. Specifically, each partici...
