Studies have suggested that patients with schizophrenia are impaired at recognizing emotions. Recently, it has been shown that the neuropeptide oxytocin can have beneficial effects on social ...behaviors.
To examine emotion recognition deficits in patients and see whether oxytocin could improve these deficits, we carried out two experiments. In the first experiment we recruited 30 patients with schizophrenia and 29 age- and IQ-matched control subjects, and gave them an emotion recognition task. Following this, we carried out a second experiment in which we recruited 21 patients with schizophrenia for a double-blind, placebo-controlled cross-over study of the effects of oxytocin on the same emotion recognition task.
In the first experiment we found that patients with schizophrenia had a deficit relative to controls in recognizing emotions. In the second experiment we found that administration of oxytocin improved the ability of patients to recognize emotions. The improvement was consistent and occurred for most emotions, and was present whether patients were identifying morphed or non-morphed faces.
These data add to a growing literature showing beneficial effects of oxytocin on social-behavioral tasks, as well as clinical symptoms.
This study examined affect as it relates to the identity management (IM) experiences of lesbian, gay, and bisexual (LGB) workers. We integrate IM theories and evidence (Chaudoir & Fisher, 2010; ...Pachankis, 2007) within the framework of affective events theory (Weiss & Cropanzano, 1996) to predict relationships among mood, identity management, and emotion at work. LGB participants rated aspects of positive and negative affect each work morning and immediately following IM situations at work over 3 weeks, making it possible to examine within-person changes and next-day consequences of IM. Our results provided little support for the notion that LGB workers' IM behaviors are driven by affect. However, there do appear to be affective consequences of IM behaviors. After concealment, participants experienced diminished positive affect and increased negative affect; in contrast, revealing was associated with increased positive affect and diminished negative affect. Additionally, these immediate affective consequences of identity management continued into the following day for some facets of affect. We examine these findings as they relate to the identity management and affect literatures, thereby building new insights into their intersections.
Objective: This study tested the interactive relationships between college students' perceived capability of regulating negative emotions and savoring positive emotions on mental health outcomes, ...including anxiety and depressive symptoms. Participants: Participants were healthy undergraduates (n = 167) recruited from two universities in Hong Kong. Methods: Students completed four scales assessing their perceived capability of using strategies to regulate negative and positive emotions and their anxiety and depressive symptoms. Results: Findings revealed that both anxiety and depressive symptoms were negatively linked to perceived capabilities of regulating negative emotions and savoring positive emotions. Furthermore, regulating negative emotions interacted with savoring positive emotions to predict anxiety symptoms. Conclusions: The need to simultaneously perform negative and positive emotion regulation is highlighted. The results suggest the priority of regulating negative emotions over savoring positive emotions in alleviating anxiety symptoms. Nevertheless, enhancing positive emotion shows greater benefits for those who are less adept at regulating negative emotions.

Rationale
There is renewed interest in the therapeutic potential of psychedelic drugs such as lysergic acid diethylamide (LSD). LSD was used extensively in the 1950s and 1960s as an adjunct in ...psychotherapy, reportedly enhancing emotionality. Music is an effective tool to evoke and study emotion and is considered an important element in psychedelic-assisted psychotherapy; however, the hypothesis that psychedelics enhance the emotional response to music has yet to be investigated in a modern placebo-controlled study.
Objectives
The present study sought to test the hypothesis that music-evoked emotions are enhanced under LSD.
Methods
Ten healthy volunteers listened to five different tracks of instrumental music during each of two study days, a placebo day followed by an LSD day, separated by 5–7 days. Subjective ratings were completed after each music track and included a visual analogue scale (VAS) and the nine-item Geneva Emotional Music Scale (GEMS-9).
Results
Results demonstrated that the emotional response to music is enhanced by LSD, especially the emotions “wonder”, “transcendence”, “power” and “tenderness”.
Conclusions
These findings reinforce the long-held assumption that psychedelics enhance music-evoked emotion, and provide tentative and indirect support for the notion that this effect can be harnessed in the context of psychedelic-assisted psychotherapy. Further research is required to test this link directly.
Research on rumination has demonstrated that compared with distraction, rumination intensifies and prolongs negative emotion. However, rumination and distraction differ both in
what
one thinks about ...and
how
one thinks about it. Do the negative outcomes of rumination result from how people think about negative events or simply that they think about them at all? To address this question, participants in 2 studies recalled a recent anger-provoking event and then thought about it in 1 of 2 ways: by ruminating or by reappraising. The authors examined the impact of these strategies on subsequent ratings of anger experience (Study 1) as well as on perseverative thinking and physiological responding over time (Study 2). Relative to reappraisal, rumination led to greater anger experience, more cognitive perseveration, and greater sympathetic nervous system activation. These findings provide compelling new evidence that how one thinks about an emotional event can shape the emotional response one has.
In line with animal models indicating sexually dimorphic effects of oxytocin (OXT) on social-emotional processing, a growing number of OXT-administration studies in humans have also reported ...sex-dependent effects during social information processing. To explore whether sex-dependent effects already occur during early, subliminal, processing stages the present pharmacological fMRI-study combined the intranasal-application of either OXT or placebo (n = 86–43 males) with a backward-masking emotional face paradigm. Results showed that while OXT suppressed inferior frontal gyrus, dorsal anterior cingulate and anterior insula responses to threatening face stimuli in men it increased them in women. In women increased anterior cingulate reactivity during subliminal threat processing was also positively associated with trait anxiety. On the network level, sex-dependent effects were observed on amygdala, anterior cingulate and inferior frontal gyrus functional connectivity that were mainly driven by reduced coupling in women following OXT. Our findings demonstrate that OXT produces sex-dependent effects even at the early stages of social-emotional processing, and suggest that while it attenuates neural responses to threatening social stimuli in men it increases them in women. Thus in a therapeutic context OXT may potentially produce different effects on anxiety disorders in men and women.
•Oxytocin (OXT) induced sex-dependent effect on BOLD level and functional connectivity.•OXT decreased neural responses to negative faces in men but increased them in women.•Increased ACC activity after OXT was positively linked with trait anxiety in women.•OXT decreased functional connectivity in women.•Sex might be an important factor moderating the putative anxiolytic effects of OXT.
We measured judgments about emotions across time. In Study 1 (N = 254) and Study 2 (N = 162), LGBTQ-Latinx, straight-Latinx, LGBTQ-White, and straight-White emerging adults rated how they would feel ...if a perpetrator acted positively (P) or negatively (N) toward them in single, isolated events. In Study 2, participants also responded to a new emotions across time task where they judged how they would feel interacting with a hypothetical perpetrator across three timepoints: (1) an initial past event, (2) a recent past event, and (3) an uncertain future-oriented event (e.g., seeing the perpetrator again). Participants further predicted their thoughts and decisions in the uncertain future-oriented event. The past emotional events appeared in various sequences (PP, NN, NP, PN). Results indicated that participants judged events as emotionally unambiguous when occurring first in a sequence or in isolation (positive events feel better than negative events). In contrast, initial events shaped emotional reactions to subsequent events: Participants responded more intensely to episodes that were preceded by events of the same valence. In addition to this augmenting effect, initial negative events were especially sticky: Participants rated a positive event following a negative event as feeling less good than when a positive event appeared first or in isolation, but they judged negative events to feel equivalently bad regardless of order. When evaluating future-oriented affective states, participants drew from the prior experiences and prioritized the recent past (more positive emotions, thoughts, and decisions for PP > NP > PN > NN). Effects replicated across all social groups.
Aim
Parents' emotions towards a child are extremely important. The Scale of Parent‐to‐Child Emotions (SPCE) consists of five basic and four self‐conscious emotion domains for assessment of parental ...emotional states. Abridgement of the SPCE is needed for research and clinical settings.
Methods
Our previous investigational data for SPCE development were used in this study. The sample of 2336 fathers and 2264 mothers, whose eldest child's age was up to 12 years old, was analyzed. Total information for each pair (form) of items corresponding to a latent trait (θ) was calculated. The form with the greatest amount of total information was selected as the best for each domain. In addition, relative efficiency for each form and correlations of raw sum scores in classical test theory (CTT) for short forms with factor scores in item response theory (IRT) were calculated.
Results
The SPCE was shortened to 18 items by selecting two items each for nine domains. Correlations of raw sum scores in CTT for short forms with factor scores in IRT were correlated strongly and significantly.
Conclusion
This abridged form of the scale, the SPCE‐18, may be applicable in a busy clinical setting or research works to investigate the trajectory of parent‐to‐child emotions across a long span of time.
•Infants progress from discrimination to recognition of emotion in faces during the first half year of life.•3.5-month-olds in the current study discriminated between body emotions.•But, ...3.5-month-olds failed to recognize emotions as measured by an intermodal matching task.•5-month-olds matched body emotions to vocal emotions.•Development of body emotion perception is similar to development of face emotion perception.
Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is unknown whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants did discriminate between body emotion videos but failed to exhibit an inversion effect, suggesting that discrimination may be based on low-level stimulus features. These results document a developmental change from discrimination based on non-emotional information at 3.5 months to recognition of body emotions at 5 months. This pattern of development is similar to face emotion knowledge development and suggests that both the face and body emotion perception systems develop rapidly during the first half year of life.
