The capacity to predict what should happen next and to minimize any discrepancy between an expected and an actual sensory input (prediction error) is a central aspect of perception. Particularly in vocal communication, the effective prediction of an auditory input that informs the listener about the emotionality of a speaker is critical. What is currently unknown is how the perceived valence of an emotional vocalization affects the capacity to predict and detect a change in the auditory input. This question was probed in a combined event-related potential (ERP) and time-frequency analysis approach...

Angelman syndrome (AS) is a neurobehavioral and genetically determined condition, which affects approximately 1 in 15,000 individuals. It is caused by various genetic mutations and deletions of the maternally-inherited UBE3A gene, on the 15q11-13 chromosomal region. The UBE3A gene, which encodes E3 ubiquitin ligase, shows tissue-specific imprinting, being expressed entirely from the maternal allele.The diagnosis of AS is confirmed either by methylation test or by mutation analysis. A more severe clinical picture is linked with the deletion phenotype...

In personal accounts, humiliation is often reported as a very intense, painful, negative emotion. We report two scenario studies in which we explored two factors that may contribute to the intense character of humiliation: (1) unwanted, negative public exposure, and (2) a threat to central aspects of one's identity. Study 1 (N = 115) assessed emotional reactions to a public insult when an audience responded with either laughter or not and when someone from the audience offered support after the insult or no support was offered...

Inside and outside of psychoanalysis, laughter has often been thought of as relating to anxiety, with the usual line being that laughter can be a response to anxiety or a way of dealing with it. This article argues that laughter cannot be said to eradicate or 'deal with' anxiety and that laughter is always unsettling precisely because it contains anxiety and indicates its continuing threat. The article discusses Freud and Lacan on anxiety, as well as Charles Mauron, an understudied writer whose Psychocritique du Genre Comique was the only sustained study of psychoanalysis and comedy until very recently...

Emotion characterises learners' feedback experiences. While the failure-to-fail literature suggests that emotion may be important, little is known about the role of emotion for educators. Secondary analyses were therefore conducted on data exploring 110 trainers' and trainees' feedback experiences. Group and individual narrative interviews were conducted across three UK sites. We analysed 333 narratives for emotional talk using textual analysis: Linguistic Inquiry and Word Count. Furthermore, thematic framework analysis was conducted on the trainer narratives to explore aspects of feedback processes that are emotional...

Responding to others' emotional expressions is an essential and early developing social skill among humans. Much research has focused on how infants process facial expressions, while much less is known about infants' processing of vocal expressions. We examined 8-month-old infants' processing of other infants' vocalizations by measuring event-related brain potentials (ERPs) to positive (infant laughter), negative (infant cries), and neutral (adult hummed speech) vocalizations. Our ERP results revealed that hearing another infant cry elicited an enhanced negativity (N200) at temporal electrodes around 200ms, whereas listening to another infant laugh resulted in an enhanced positivity (P300) at central electrodes around 300ms...

Anna E Reinert, James A Simon
INTRODUCTION: The study of the human orgasm has shown a core set of physiologic and psychological symptoms experienced by most individuals. The study of normal sheds light on the abnormal and has spotlighted rare physical and psychological symptoms experienced by some individuals in association with orgasm. These phenomena are rare and, as is typical of rare phenomena, their documentation in the medical literature is largely confined to case studies. AIM: To identify peri-orgasmic phenomena, defined as unusual physical or psychological symptoms subjectively experienced by some individuals as part of the orgasm response, distinct from the usual or normal orgasm response...

Synthetic Cannabinoids (SC) are the widest and most diffused class of Novel Psychoactive Substances. SC are chemically heterogeneous and structurally dissimilar from delta-9-tetrahydrocannabinol, being full agonists of the endocannabinoid system receptors CB1 and CB2. Desired effects include euphoria, talkativeness, feelings of joy and laughter, relaxation. With respect to cannabis, SC intake may also be associated with quicker arise of the effects, shorter duration of action, and larger levels of hangover...

The study aimed to explore the humor processing elicited through the manipulation of artistic drawings. Using the Comprehension-Elaboration Theory of humor as the main research background, the experiment manipulated the head portraits of celebrities based on the independent variables of facial deformation (large/small) and addition of affective features (positive/negative). A 64-channel electroencephalography was recorded in 30 participants while viewing the incongruous drawings of celebrities. The electroencephalography temporal and spectral responses were measured during the three stages of humor which included incongruity detection, incongruity comprehension and elaboration of humor...

The aim of this study was to identify the challenges encountered by dental assisting students, especially those from underrepresented racial and ethnic groups (UREG), that affected their achieving academic success. In 2016, directors of the nine northern California dental assisting programs were contacted via email to explain the study and request an opportunity to administer the 26-item survey to their currently enrolled students. Student responses were entered into a survey research program, which tabulated the data and calculated the frequency of responses to each item...

The longitudinal posttraumatic stress responses and resilient factors after the Fukushima Daiichi Nuclear Power Plant are yet unknown. Here we attempted to quantify the patterns of the course of posttraumatic stress disorder (PTSD) symptoms and we explored the factors associated with psychological recovery. The subjects were 12 371 residents in the municipalities categorized as the forced evacuated area. We categorized the subjects' PTSD symptoms into 4 groups: Chronic, Resistant, Recovered, and Non-recovered...

Treatment of painful internal snapping hip via arthroscopic release of the iliopsoas tendon is becoming the preferred option over open techniques because of the benefits of minimal dissection and fewer complications. However, complications do occur with arthroscopic techniques as well. We present the case of a 33-year-old woman who presented with painful internal snapping of her right hip and underwent arthroscopic release of the iliopsoas tendon. Following the procedure she continued to complain of pain in her groin and was therefore investigated further with a magnetic resonance imaging (MRI) which revealed a swelling near the femoral circumflex vessels...

The infection control (IC) practices of dental hygienists, who were practicing in states with and without mandatory continuing education (CE) related to IC, were compared using a nationwide survey approach. The percentages of respondents from states with mandated IC CE, who reported compliance with 8 practices described in the current IC guidelines and acquiring more CE units and taking more recent IC CE, were greater (P < .005) than the percentages of respondents from states without the requirement.

BACKGROUNDS: The purpose of the study was to assess the clinical outcome of patients with situational syncope (SS) compared to patients with vasovagal syncope (VVS). METHODS: We assessed the prevalence, patients' characteristics, and outcome of consecutive patients with SS and VVS who presented to the Faint and Fall Clinic (University of Wisconsin) between January 2013 and December 2015. RESULTS: SS was found in 55/1,401 (4.0%) syncope patients with follow-up data available in 47 patients: defecation (n = 16), micturition (n = 15), cough (n = 10), swallow (n = 3), laughter (n = 1), sneeze (n = 1), and cough plus laughter (n = 1)...

Gelastic seizures (GS) describe ictal laughter and are associated with hypothalamic lesions, as well as other cortical areas. Dacrystic seizures (DS), characterized by ictal crying, also have been reported in hypothalamic lesions and focal epilepsy. We describe a young girl with drug resistant focal dyscognitive seizures associated with gelastic and dacrystic features. However, neither laughter nor crying was correlated with a stereotyped electroencephalographic (EEG) pattern or involvement of a particular brain region...

BACKGROUND: We performed an observational study of laughter during seminaturalistic conversations between patients with dementia and familial caregivers. Patients were diagnosed with (1) behavioural variant frontotemporal dementia (bvFTD), (2) right temporal variant frontotemporal dementia (rtFTD), (3) semantic variant of primary progressive aphasia (svPPA), (4) non-fluent variant primary progressive aphasia (nfvPPA) or (5) early onset Alzheimer's disease (eoAD). We hypothesised that those with bvFTD would laugh less in response to their own speech than other dementia groups or controls, while those with rtFTD would laugh less regardless of who was speaking...

The ways in which humour can be used are related to the manifold interpersonal functions humour can serve, some of which are positive, and some negative. In the present study, phasic changes in the functional coupling of prefrontal and posterior cortex (EEG coherence) during other people's auditory displays of happy and sad mood were recorded to predict people's typical use of humour in social interactions. Greater use of benevolent humour, the intentions of which are in keeping with the characteristics of "laughing-with" humour, was associated with greater decreases of prefrontal-posterior coupling during the processing of happy laughter...

Cataplexy is a hallmark of narcolepsy characterized by the sudden uncontrollable onset of muscle weakness or paralysis during wakefulness. It can occur spontaneously, but is typically triggered by positive emotions such as laughter. Although cataplexy was identified >130 years ago, its neural mechanism remains unclear. Here, we show that a newly identified GABA circuit within the central nucleus of the amygdala (CeA) promotes cataplexy. We used behavioral, electrophysiological, immunohistochemical, and chemogenetic strategies to target and manipulate CeA activity selectively in narcoleptic (orexin(-/-)) mice to determine its functional role in controlling cataplexy...
