- Research suggests that visual impressions of natural compared with urban environments facilitate recovery after psychological stress. To test whether auditory stimulation has similar effects, 40 subjects were exposed to sounds from nature or noisy environments after a stressful mental arithmetic task. Skin conductance level (SCL) was used to index sympathetic activation, and high frequency heart rate variability (HF HRV) was used to index parasympathetic activation. Although HF HRV showed no effects, SCL recovery tended to be faster during natural sound than noisy environments. These results suggest that nature sounds facilitate recovery from sympathetic activation after a psychological stressor.

- Family relations may constitute a risk for developing eating problems. Not enough is known about parent-child relationship quality and upbringing in food situations. Self-report data from 80 high school students (45 males) showed that females had more eating problems than males, and their problems were related both to insecure mother attachment, controlling for body/weight dissatisfaction, and to more memories of childhood food rules. Secure mother attachment was related to decreased eating problems, via increasing body/weight satisfaction. Especially the mother- daughter relationship seems to affect adolescent girls' eating habits and can either protect against or enhance the risk for eating problems.

- Decision-makers tend to change the psychological attractiveness of decision alternatives in favour of their own preferred alternative after the decision is made. In two experiments, the present research examined whether such decision consolidation occurs also among individual group members in a large group decision-making situation. High-school students were presented with a decision scenario on an important issue in their school. The final decision was made by in-group authority, out-group authority or by majority after a ballot voting. Results showed that individual members of large groups changed the attractiveness of their preferred alternative from a pre- to a post decision phase, that these consolidation effects increased when decisions were made by in-group members and when participants identified strongly with their school. Implications of the findings for understanding of group behavior and subgroup relations are discussed.

- Much of identity formation processes nowadays takes place online, indicating that intergroup differentiation may be found in online communities. This paper focuses on identity formation processes in an open online xenophobic, anti-immigrant, discussion forum. Open discussion forums provide an excellent opportunity to investigate open interactions that may reveal how identity is formed and how individual users are influenced by other users. Using computational text analysis and Linguistic Inquiry Word Count (LIWC), our results show that new users change from an individual identification to a group identification over time as indicated by a decrease in the use of “I” and increase in the use of “we”. The analyses also show increased use of “they” indicating intergroup differentiation. Moreover, the linguistic style of new users became more similar to that of the overall forum over time. Further, the emotional content decreased over time. The results indicate that new users on a forum create a collective identity with the other users and adapt to them linguistically.

- Empirical studies have indicated that listeners value music primarily for its ability to arouse emotions. Yet little is known about which emotions listeners normally experience when listening to music, or about the causes of these emotions. The goal of this study was therefore to explore the prevalence of emotional reactions to music in everyday life and how this is influenced by various factors in the listener, the music, and the situation. A self-administered mail questionnaire was sent to a random and nationally representative sample of 1,500 Swedish citizens between the ages of 18 and 65, and 762 participants (51%) responded to the questionnaire. Thirty-two items explored both musical emotions in general (semantic estimates) and the most recent emotion episode featuring music for each participant (episodic estimates). The results revealed several variables (e.g., personality, age, gender, listener activity) that were correlated with particular emotions. A multiple discriminant analysis indicated that three of the most common emotion categories in a set of musical episodes (i.e., happiness, sadness, nostalgia) could be predicted with a mean accuracy of 70% correct based on data obtained from the questionnaire. The results may inform theorizing about musical emotions and guide the selection of causal variables for manipulation in future experiments.

- Introduction: Schizophrenia patients show decreased ability to identify emotion based upon tone of voice (voice emotion recognition), along with deficits in basic auditory processing. Interrelationship among these measures is poorly understood. Methods: Forty-one patients with schizophrenia/schizoaffective disorder and 41 controls were asked to identify the emotional valence (happy, sad, angry, fear, or neutral) of 38 synthesized frequency-modulated (FM) tones designed to mimic key acoustic features of human vocal expressions. The mean (F0M) and variability (F0SD) of fundamental frequency (pitch) and absence or presence of high frequency energy (HF500) of the tones were independently manipulated to assess contributions on emotion identification. Forty patients and 39 controls also completed tone-matching and voice emotion recognition tasks. Results: Both groups showed a nonrandom response pattern (P < .0001). Stimuli with highest and lowest F0M/F0SD were preferentially identified as happy and sad, respectively. Stimuli with low F0M and midrange F0SD values were identified as angry. Addition of HF500 increased rates of angry and decreased rates of sad identifications. Patients showed less differentiation of response across frequency changes, leading to a highly significant between-group difference in response pattern to maximally identifiable stimuli (d = 1.4). The differential identification pattern for FM tones correlated with deficits in basic tone-matching ability (P = .01), voice emotion recognition (P < .001), and negative symptoms (P < .001).Conclusions: Specific FM tones conveyed reliable emotional percepts in both patients and controls and correlated highly with deficits in ability to recognize information based upon tone of voice, suggesting significant bottom-up contributions to social cognition and negative symptom impairments in schizophrenia.

Emotion appraisal dimensions can be inferred from vocal expressions
- 2012

- Vocal expressions are thought to convey information about speakers’ emotional states but may also reflect the antecedent cognitive appraisal processes that produced the emotions. We investigated the perception of emotion-eliciting situations on the basis of vocal expressions. Professional actors vocally portrayed different emotions by enacting emotion-eliciting situations. Judges then rated these expressions with respect to the emotion-eliciting situation described in terms of appraisal dimensions (i.e., novelty, intrinsic pleasantness, goal conduciveness, urgency, power, self- and other responsibility, and norm compatibility), achieving good agreement. The perceived appraisal profiles for the different emotions were generally in accord with predictionsbased on appraisal theory. The appraisal ratings also correlated with a variety of acoustic measures related to pitch, intensity, voice quality, and temporal characteristics. Results suggest that several aspects of emotion-eliciting situations can be inferred reliably and validly from vocal expressions which, thus, may carry information about the cognitive representation of events.

Exploring the determinants of the graded structure of vocal emotion expressions
- 2012

Tidskriftsartikel (refereegranskat)abstract
- We examined what determines the typicality, or graded structure, of vocal emotion expressions. Separate groups of judges rated acted and spontaneous expressions of anger, fear, and joy with regard to their typicality and three main determinants of the graded structure of categories: category members’ similarity to the central tendency of their category (CT); category members’ frequency of instantiation, i.e., how often they are encountered as category members (FI); and category members’ similarity to ideals associated with the goals served by its category, i.e., suitability to express particular emotions. Partial correlations and multiple regression analysis revealed that similarity to ideals, rather than CT or FI, explained most variance in judged typicality. Results thus suggest that vocal emotion expressions constitute ideal-based goal-derived categories, rather than taxonomic categories based on CT and FI. This could explain how prototypical expressions can be acoustically distinct and highly recognisable but occur relatively rarely in everyday speech.

Neurofunctional correlates of expressed vocal affect in social phobia

- We investigated the neural correlates of expressed vocal affect in patients with social phobia. A group of 36 patients performed an anxiogenic public-speaking task while regional cerebral blood flow (rCBF) was assessed using oxygen-15 positron emission tomography. The patients’ speech was recorded and content masked using low-pass filtering (which obscures linguistic content but preserves nonverbal affective cues). The content-masked speech samples were then evaluated with regard to their level of vocally expressed nervousness. We hypothesized that activity in prefrontal and subcortical brain areas previously implicated in emotion regulation would be associated with the degree of expressed vocal affect. Regression analyses accordingly revealed significant negative correlations between expressed vocal affect and rCBF in inferior frontal gyrus, putamen, and hippocampus. Further, functional connectivity was revealed between inferior frontal gyrus and (a) anterior cingulate cortex and (b) amygdala and basal ganglia. We suggest that brain areas important for emotion regulation may also form part of a network associated with the modulation of affective prosody in social phobia.

Konferensbidrag (refereegranskat)abstract
- We introduce the Vocal Expressions of Nineteen Emotions across Cultures (VENEC) corpus and present results from initial evaluation efforts using a novel method of annotating emotion appraisals. The VENEC corpus consists of 100 professional actors from 5 English speaking cultures (USA, India, Kenya, Singapore, and Australia) who vocally expressed 19 different affects/emotions (affection, amusement, anger, contempt, disgust, distress, fear, guilt, happiness, interest, lust, negative surprise, neutral, positive surprise, pride, relief, sadness, serenity, and shame), each with 3 levels of emotion intensity, by enacting finding themselves in various emotion-eliciting situations. In all, the corpus contains approximately 6,500 stimuli offering great variety of expressive styles for each emotion category due to speaker, culture, and emotion intensity effects. All stimuli have further been acoustically analyzed regarding pitch, intensity, voice quality, and durational cues. In the appraisal rating study, listeners rated a selection of VENEC-stimuli with regard to the characteristics of the emotion eliciting situation, described in terms of 8 emotion appraisal dimensions (novelty, intrinsic pleasantness, goal conduciveness, urgency, power, self- and other-responsibility, and norm compatibility). First, results showed that the inter-rater reliability was acceptable for all scales except responsibility. Second, the perceived appraisal profiles for the different vocal expressions were generally in accord with predictions based on appraisal theory. Finally, listeners’ appraisal ratings on each scale were significantly correlated with several acoustic characteristics. The results show that listeners can reliably infer several aspects of emotion-eliciting situations from vocal affect expressions, and thus suggest that vocal affect expressions may carry cognitive representational information.
