Both low and high spatial frequencies drive the early posterior negativity in response to snake stimuli.

Previous event-related potential (ERP) studies have shown that snake pictures elicit greater early posterior negativity (EPN) compared to other animal pictures. The EPN reflects early selective visual processing of emotionally significant stimuli. Evidence for the role that high and low spatial frequencies play in the early detection of snakes is still inconsistent.

Investigating Managers' Fine-Grained Evaluation Processes in Organizations: Exploring Two Dual-Process Perspectives.

The dual-process theory is a significant theory in both organizational theory and social psychology and two conjectures about this theory are considered in this manuscript; the default-interventionist vs. parallel-competitive account. Our research goal is to empirically investigate these two views.

Early posterior negativity in humans to pictures of snakes and spiders: effects of proximity.

Snakes have proven to drive early attentional capture due to their evolutionary importance, as reflected by the early posterior negativity (EPN). The EPN snake effect might be partly driven by the proximity of the animal. In this study, by employing full-body (medium shot) and head-focused (close-up) pictures, we investigated whether the relative nearness (proximity) of the animal on the picture affects the snake EPN effect.

The effect of fearful expressions on recognition memory for faces: Behavioral and electrophysiological data.

Facial expressions affect memory for face identity. We tested how fearful expressions modulate recognition memory for faces. In two studies, participants completed a continuous recognition task with fearful and neutral faces while their electroencephalogram was recorded.

Blurring attenuates the early posterior negativity in response to snake stimuli.

Previous event-related potential studies have reported enhanced Early Posterior Negativity (EPN) in response to snake pictures compared to pictures of other animals. This EPN snake effect may be partly driven by specific snake skin patterns. In this study, by using blurred pictures to make these patterns less visible, we explored whether the relative absence of such local features will attenuate the EPN snake effect.

Romantic love and attention: Early and late event-related potentials.

The beloved likely attracts attention. We tested whether the beloved captures early automatic attention, as indicated by an early posterior negativity (EPN) in a typical rapid serial visual presentation (RSVP) task, while replicating previous findings that the beloved receives sustained motivated attention, as indicated by an enhanced late positive potential (LPP) in a standard passive viewing task. Participants viewed beloved, friend, and stranger pictures in RSVP and standard passive viewing tasks.

Event-related potentials in response to feedback following risk-taking in the hot version of the Columbia Card Task.

Given the importance of risk-taking in individuals' personal and professional life, several behavioral tasks for measuring the construct have been developed. Recently, a new task was introduced, the Columbia Card Task (CCT). This task measures participants' risk levels and establishes how sensitive participants are to gains, losses, and probabilities when taking risk.

The effect of mouth opening in emotional faces on subjective experience and the early posterior negativity amplitude.

Previous studies have examined the role of the eye region in emotional expressions, but the mouth region is understudied. The main goal of this study was to examine how mouth opening in emotional faces affects subjective experience and early automatic attentional capture, as measured by the early posterior negativity (EPN) amplitude. Participants in two studies viewed angry, happy, and neutral faces with mouths open and closed while their electroencephalogram was recorded.

Cognitive reappraisal of snake and spider pictures: An event-related potentials study.

Fear of snakes and spiders are common animal phobias. Emotion regulation can change the response to emotional stimuli, including snakes and spiders. It is well known that emotion regulation modulates the late positive potential (LPP), which reflects sustained motivated attention.

Spontaneous resting-state gamma oscillations are not predictive of autistic traits in the general population.

The autism spectrum hypothesis states that not only diagnosed individuals but also individuals from the general population exhibit a certain amount of autistic traits. While this idea is supported by neuroimaging studies, there have been few electrophysiological studies. In particular, there have been no spontaneous resting-state studies yet.

Enhanced early visual processing in response to snake and trypophobic stimuli.

Background: Trypophobia refers to aversion to clusters of holes. We investigated whether trypophobic stimuli evoke augmented early posterior negativity (EPN).

Methods: Twenty-four participants filled out a trypophobia questionnaire and watched the random rapid serial presentation of 450 trypophobic pictures, 450 pictures of poisonous animals, 450 pictures of snakes, and 450 pictures of small birds (1800 pictures in total, at a rate of 3 pictures/s).

Early visual processing of snakes and angry faces: An ERP study.

Snakes and angry faces are common fear stimuli and both elicit an Early Posterior Negativity (EPN) in the event-related potential, which indicates that they capture early automatic visual attention. But because snakes have been a predatory threat for primates since long before communication through facial expressions evolved, we tested the hypothesis that the EPN for snakes would be more pronounced than the EPN for angry faces. We carefully controlled for differences between reptiles and faces by using lizards and neutral faces as control stimuli.

Preferential processing of task-irrelevant beloved-related information and task performance: Two event-related potential studies.

People who are in love have better attention for beloved-related information, but report having trouble focusing on other tasks, such as (home)work. So, romantic love can both improve and hurt cognition. Emotional information is preferentially processed, which improves task performance when the information is task-relevant, but hurts task performance when it is task-irrelevant.

Self-Report and Brain Indicators of Impaired Emotion Regulation in the Broad Autism Spectrum.

Although not used as a diagnostic criterion, impaired emotion regulation is frequently observed in autism. The present study examined self-reported use of emotion regulation strategies in individuals scoring low or high on autistic traits. In addition, the late positive potential, which is sensitive to emotional arousal, was used to examine the effect of one strategy, reappraisal.

Cognitive control in young heavy drinkers: An ERP study.

Substance use disorders have been frequently linked to an impaired cognitive control system. Whether this impaired control is also present in young adults who heavily drink alcohol is still subject to debate. The present study investigated possible impairments in cognitive control in heavy drinkers using behavioral and electrophysiological (EEG) measures.

Snake scales, partial exposure, and the Snake Detection Theory: A human event-related potentials study.

Studies of event-related potentials in humans have established larger early posterior negativity (EPN) in response to pictures depicting snakes than to pictures depicting other creatures. Ethological research has recently shown that macaques and wild vervet monkeys respond strongly to partially exposed snake models and scale patterns on the snake skin. Here, we examined whether snake skin patterns and partially exposed snakes elicit a larger EPN in humans.

Regulation of Romantic Love Feelings: Preconceptions, Strategies, and Feasibility.

Love feelings can be more intense than desired (e.g., after a break-up) or less intense than desired (e.

Implicit emotion regulation in the context of viewing artworks: ERP evidence in response to pleasant and unpleasant pictures.

Presenting affective pictures as a work of art could change perceivers' judgment and strength in emotional reactions. Aesthetic theory states that perceivers of art emotionally distance themselves, allowing them to appreciate works of art depicting gruesome events. To examine whether implicit emotion regulation is induced by an art context, we assessed whether presenting pleasant and unpleasant IAPS pictures as either "works of art comprising paintings, digital renderings, and photographs of staged scenes" or "photographs depicting real events" modulated perceivers' Late Positive Potentials (LPP) and likability ratings.

Curvilinear shapes and the snake detection hypothesis: An ERP study.

Consistent with the snake detection hypothesis, previous ERP studies have established a larger early posterior negativity (EPN) in response to pictures depicting snakes than to pictures depicting other creatures. Here, we examined to what extent the curvilinear shape of the snake's body drives the larger EPN. To this end, we employed pictures of threatening and nonthreatening species with or without typical curvature.

Testing the snake-detection hypothesis: larger early posterior negativity in humans to pictures of snakes than to pictures of other reptiles, spiders and slugs.

According to the snake detection hypothesis (Isbell, 2006), fear specifically of snakes may have pushed evolutionary changes in the primate visual system allowing pre-attentional visual detection of fearful stimuli. A previous study demonstrated that snake pictures, when compared to spiders or bird pictures, draw more early attention as reflected by larger early posterior negativity (EPN). Here we report two studies that further tested the snake detection hypothesis.

"I am resting but rest less well with you." The moderating effect of anxious attachment style on alpha power during EEG resting state in a social context.

We took EEG recordings to measure task-free resting-state cortical brain activity in 35 participants under two conditions, alone (A) or together (T). We also investigated whether psychological attachment styles shape human cortical activity differently in these two settings. The results indicate that social context matters and that participants' cortical activity is moderated by the anxious, but not avoidant attachment style.

Increased attention and memory for beloved-related information during infatuation: behavioral and electrophysiological data.

Emotionally salient information is well attended and remembered. It has been shown that infatuated individuals have increased attention for their beloved. It is unknown whether this attention bias generalizes to information related to the beloved.

Up-regulation of emotional responses to reward-predicting stimuli: an ERP study.

Altered reward processing is a hallmark symptom of many psychiatric disorders. It has recently been shown that people are capable of down-regulating reward processing. Here, we examined whether people are capable of up-regulating emotional responses to reward-predicting stimuli.

Age-related differences in brain electrical activity during extended continuous face recognition in younger children, older children and adults.

To examine the development of recognition memory in primary-school children, 36 healthy younger children (8-9 years old) and 36 healthy older children (11-12 years old) participated in an ERP study with an extended continuous face recognition task (Study 1). Each face of a series of 30 faces was shown randomly six times interspersed with distracter faces. The children were required to make old vs.

Electrophysiology of appetitive taste and appetitive taste conditioning in humans.

The present study examines two novel aspects of appetitive processing and conditioning: the electrophysiological response to (a) the appetitive taste of a sweet fluid and (b) appetitively/taste conditioned visual stimuli. Event-related potentials (ERPs) were recorded from 32 subjects while they performed a taste conditioning task, in which two symbols were paired with a sweet or a neutral fluid. The results show a clear P1/N1/P2 complex, and a late positive potential (P3) with maxima at right fronto-central electrode sites, in response to the taste stimuli.
