Auditory affective norms for German: testing the influence of depression and anxiety on valence and arousal ratings

Background

The study of emotional speech perception and emotional prosody necessitates stimuli with reliable affective norms. However, ratings may be affected by the participants'' current emotional state as increased anxiety and depression have been shown to yield altered neural responding to emotional stimuli. Therefore, the present study had two aims, first to provide a database of emotional speech stimuli and second to probe the influence of depression and anxiety on the affective ratings.

Methodology/Principal Findings

We selected 120 words from the Leipzig Affective Norms for German database (LANG), which includes visual ratings of positive, negative, and neutral word stimuli. These words were spoken by a male and a female native speaker of German with the respective emotional prosody, creating a total set of 240 auditory emotional stimuli. The recordings were rated again by an independent sample of subjects for valence and arousal, yielding groups of highly arousing negative or positive stimuli and neutral stimuli low in arousal. These ratings were correlated with participants'' emotional state measured with the Depression Anxiety Stress Scales (DASS). Higher depression scores were related to more negative valence of negative and positive, but not neutral words. Anxiety scores correlated with increased arousal and more negative valence of negative words.

Conclusions/Significance

These results underscore the importance of representatively distributed depression and anxiety scores in participants of affective rating studies. The LANG-audition database, which provides well-controlled, short-duration auditory word stimuli for the experimental investigation of emotional speech is available in Supporting Information S1.     

EMOTIONAL PROBLEMS IN CHILDREN—The Uses of Drugs in Therapeutic Management

Emotional disturbances in children may be due to an anxiety state, to obsessive-compulsive neurosis, to schizophrenia or to a brain injury causing a behavior disorder. Children in an anxiety state have difficulty in school because anxiety interferes with concentration, impairs memory and makes decisions difficult. Consequently, these children often fear school and express their anxiety by behavior disturbances which alienate them from parents and teachers.There are a number of chemotherapeutic agents physicians can use as a part of the treatment of emotionally disturbed children. Phenobarbital is valuable for short-term therapy for the anxious child. Meprobamate also may be prescribed for anxiety reactions. It is of limited value for the hyperkinetic and obsessive-compulsive child and of no value in the schizophrenic child. Atarax (hydroxyzine dihydrochloride) is beneficial for the neurotic and hyperkinetic brain-injured child. Children with severe anxiety reactions and schizophrenic disorders respond best to chlorpromazine or reserpine.It must be emphasized that drug therapy is a part of the total therapeutic attack on the emotional problems of children.     

Some etiologic factors of speech comprehension disturbances

Disturbances of speech comprehension were analyzed in a prospective study of 97 children, aged from 23 to 77 months. Pregnancy, birth and early psychomotor development were normal for all the children and no focus of neurological deficit was found. A tonal audiometer did not detect any auditory disturbances, and psychological testing with non-verbal tests showed normal mental functioning for the age. In this group of selected subjects, family and personal case histories were taken. In addition, a detailed neurological physical examination, standard EEG and auditory evoked potentials, and a psychiatric examination were performed during several appointments. The results showed that disturbances in speech comprehension were more frequent in boys, and that in 13.4% of cases it was caused by pervasive developmental disturbances and in 41.24% of cases by external stimulating factors of speech development (pedagogy, social and emotional stimulation and growing up in a multilingual community). The study emphasizes the importance of non-verbal methods for the study of speech and the use of auditory evoked potentials.     

Narrative Length and Speech Rate in Battered Women

Narrative length and speech rate of traumatic recollections have been previously associated with different emotions and adjustment trajectories after trauma. However, the evidence is limited and the results are mixed. The present study aimed to evaluate length (i.e., word count) and speech rate (i.e., words per minute) in narratives of events with different valence (i.e., neutral, positive, and negative/traumatic) by 50 battered women (trauma group) and 50 non-traumatized women (controls). The results showed that traumatic narratives by the trauma group were longer than those by the control group. Moreover, they were inversely related to time since the event and anxiety during disclosure, whereas the speech rate was also inversely associated with anxiety, as well as with peritraumatic dissociation and avoidance. The shorter narratives for positive events and a decelerated speech pattern for traumatic experiences predicted psychological symptoms. Additionally, the individual’s emotional state predicted narrative aspects, with bidirectional effects. Our findings showed that linguistic characteristics of traumatic narratives (but also of narratives of positive events) revealed information about how the victims elaborated autobiographical memories and coped with the trauma.     

Gender related differences in quality of life and affective status in patients with inflammatory bowel disease

According to the literature, quality of life has been shown to be reduced in females compared with males with Inflammatory Bowel Disease (IBD). Psychosocial factors are also playing an important role in IBD, especially emotional lability. The aims of study was to investigate the sex differences in general and specific health-related quality of life (HRQoL), anxiety and depression in IBD patients. Hundred and twelve outpatients of the Gastroenterology Division, Clinical Hospital Centre Rijeka, were enrolled in our study and divided in two groups: 50 females (31 with ulcerative colitis, UC and 19 with Crohn disease, CD) and 62 males (30 with UC and 32 with CD), age range 19 to 74 (M = 41.46; SD = 13.06). Most patients have been in long clinical remission or with mild disease according to Clinical Disease Activity Index (CDAI) score for CD and Clinical Activity Index (CAI) score for UC. There were significant differences in physical (F = 13.96, p < .0001) and mental (F = 9.44, p < .001) component of the general HRQoL, emotional domain ((F = 9.26, p < .001) and bowel symptoms (F = 7.04, p < .001) of the Inflammatory Bowel Disease Quality of life (IBDQoL), as well as, in anxiety (F = 7.03, p < .001) and depression (F = 12.09, p < .0001) between men and women with IBD. Women have expressed significantly lower level of the general HRQoL and more emotional disturbances connected with their disease as well as more frequent bowel symptoms compared with men. Effect sizes of those differences were large. Results of this study confirm that women with IBD are more prone to the negative impact of the disease on their HRQoL than men. Women with higher level of depression and anxiety experienced more emotional disturbances, bowel and systemic symptoms and lower general HRQoL. These results should deserve more considerations in the clinical treatment of IBD patients.     

Psychiatric consequences of road traffic accidents.

OBJECTIVE--To determine the psychiatric consequences of being a road traffic accident victim. DESIGN--Follow up study of road accident victims for up to one year. SETTING--Emergency department of the John Radcliffe Hospital, Oxford. SUBJECTS--188 consecutive road accident victims aged 18-70 with multiple injuries (motorcycle or car) or whiplash neck injury, who had not been unconscious for more than 15 minutes, and who lived in the catchment area. MAIN OUTCOME MEASURES--Present state examination "caseness"; post-traumatic stress disorder and travel anxiety; effects on driving and on being a passenger. RESULTS--Acute, moderately severe emotional distress was common. Almost one fifth of subjects, however, suffered from an acute stress syndrome characterised by mood disturbance and horrific memories of the accident. Anxiety and depression usually improved over the 12 months, though one tenth of patients had mood disorders at one year. In addition, specific post-traumatic symptoms were common. Post-traumatic stress disorder occurred during follow up in one tenth of patients, and phobic travel anxiety as a driver or passenger was more common and frequently disabling. Emotional disorder was associated with having pre-accident psychological or social problems and, in patients with multiple injuries, continuing medical complications. Post-traumatic syndromes were not associated with a neurotic predisposition but were strongly associated with horrific memories of the accident. They did not occur in subjects who had been briefly unconscious and were amnesic for the accident. Mental state at three months was highly predictive of mental state at one year. CONCLUSIONS--Psychiatric symptoms and disorder are frequent after major and less severe road accident injury. Post-traumatic symptoms are common and disabling. Early information and advice might reduce psychological distress and travel anxiety and contribute to road safety and assessing "nervous shock."     

P300 component changes of the auditory event-related potential in the patients with typical and atypical panic attacks

84 patients with panic disorders and 36 healthy control subjects with use of clinico-neurologic technique, psychometric, neuropsychological and the neurophysiological method of auditory event-related potentials P300 were examined. Patients with panic disorders were characterized by the raised level of anxiety, depression and cognitive function disturbances in the form of decrease of short-term memory and attention insufficiency in comparison with the healthy control subjects. Patients with atypical panic disorders differed from the patients with typical panic disorders by lower level of anxiety, a greater degree of depression and more expressed cognitive function disturbances. In comparison with the healthy control subjects with atypical panic disorders the decrease of P300 peak amplitude was observed, with typical--its augmentation. It is supposed, that P300 peak change is bound to dysfunction of temporal-limbic-reticular brain structures.     

The effect of fermented-milk bifidumbacterin on the intestinal microflora of test pilots]

Bacteriological study of intestinal microflora in test pilots, regularly exposed to excessive physical, as well as nervous and emotional strain, has revealed changes in the composition of their intestinal microflora. Correction of microflora by means of bifidumbacterin, a curative lactic fermentation alimentary product, was carried out. Rapid and effective restoration of intestinal microflora and improvement of the general state of patients were noted, which made it possible to recommend this product as a prophylactic remedy for subjects at risk of development of dysbiotic disturbances.     

EEG Correlates of Anxiety and Emotional Stability in Adult Healthy Subjects

We studied peculiarities of the spectral characteristics of EEG in 111 healthy adult subjects of both sexes. The levels of situative anxiety (anxiety state) and personal anxiety were estimated using the Spielberger–Khanin test system. To estimate anxiety-related properties of the personality, Cattel’s technique 16 PF (form А) was used. Estimates of situative anxiety demonstrated only two cases of positive correlation with the spectral power density (SPD) of EEG rhythms (SPDs of the beta2 rhythm in the right-hemisphere temporal and occipital regions; recording with the eyes open). Estimates of personal anxiety positively correlated with the SPDs of the beta1 and (especially) beta2 EEG rhythms. Under conditions with the eyes open, the number of significant correlations was greater, and correlations themselves were tighter than with the eyes closed. The closest correlations of the estimates of personal anxiety with the SPDs of the beta rhythm were found in frontal and central leads of both hemispheres and in parietal and occipital loci of the right hemisphere. Only a single case of correlation of the alpha rhythm SPD with personal anxiety (negative correlation, a parietal lead in the left hemisphere) was found. At the same time, rather numerous correlations of the alpha rhythm expression with an index congeneric to anxiety, the C factor by the Cattel’s questionnaire (emotional stability/instability), were found. Thus, the intense beta EEG rhythm can be considered an electrographic correlate of high situative and personal anxieties. At the same time, the alpha rhythm power correlates with the emotional stability of the individual. We suppose that persons with a well-developed alpha rhythm are characterized by active and stable functioning of the cerebral dopaminergic system; this simultaneously serves as a pre-requisite of high emotional stability and social adaptability.     

Effects of subthalamic nucleus stimulation on emotional prosody comprehension in Parkinson's disease

Background

Although impaired decoding of emotional prosody has frequently been associated with Parkinson''s disease (PD), to date only few reports have sought to explore the effect of Parkinson''s treatment on disturbances of prosody decoding. In particular, little is known about how surgical treatment approaches such as high frequency deep brain stimulation (DBS) affect emotional speech perception in patients with PD. Accordingly, the objective of this study was to evaluate the effect of subthalamic nucleus (STN) stimulation on prosody processing.

Methodology/Principal Findings

To this end the performance of 13 PD patients on three tasks requiring the decoding of emotional speech was assessed and subsequently compared to the performance of healthy control individuals. To delineate the effect of STN-DBS, all patients were tested with stimulators turned on as well as with stimulators turned off. Results revealed that irrespective of whether assessments were made “on” or “off” stimulation, patients'' performance was less accurate as compared to healthy control participants on all tasks employed in this study. However, while accuracy appeared to be unaffected by stimulator status, a facilitation of reactions specific to highly conflicting emotional stimulus material (i.e. stimulus material presenting contradicting emotional messages on a verbal and non-verbal prosodic level) was observed during “on” stimulation assessments.

Conclusion

In sum, presented results suggest that the processing of emotional speech is indeed modulated by STN-DBS. Observed alterations might, on the one hand, reflect a more efficient processing of highly conflicting stimulus material following DBS. However, on the other hand, given the lack of an improvement in accuracy, increased impulsivity associated with STN stimulation needs to be taken into consideration.     

Changes in the tempo parameters of speech in the dynamics of depressions]

The paper is devoted to study of methods for evaluation of the state of depressive patients by the parameters characterizing the rate of their speech. It is found that elongation of mean durations of pauses and decrease of mean durations of clear speech at the height of pathologic process testify to the presence of depressive affect of anguish. Short pauses with long portions of clear speech are typical for the patients with affects of alarm. In the study of psychomotor disturbances of depressive patients it was shown that the motor component was the most reflected in such characteristic of the speech rate as mean duration of clear speech and the ideatory one--in mean duration of pauses. Analysis of speech rate characteristics confirmed the significance of the ideatory inhibition in diagnostics of alarm endogenous depressions and ideatory excitation at psychogenic variants.     

Evaluation of the functional state of operators with allowance for individual psychological characteristics

This article deals with the features of the evaluation of changes in the functional state during the professional activity of operators. We estimated the dynamics of the functional state and efficiency of operators under the effect of aircraft noise and individual psychophysiological characteristics. We also investigated changes in the functional state of operators depending on their psychological characteristics. It was found that changes in the functional state of the organism in operators with high levels of anxiety, low degrees of extraversion, and high emotional lability were more pronounced in the modeling of operator activity with exposure to aircraft noise, as evidenced by significant changes in psychophysiological parameters. After 60 minutes of noise stress, the latent period of a simple and a complex sensorimotor reaction in introverts increased by 9.1% (p < 0.05) and 8.1% (p < 0.05), respectively. In the group of subjects with high levels of anxiety, there was a decrease in the general state, activity, and mood by 18.9% (p < 0.01), 20.9%, and 14.9% (p < 0.05), respectively, and a decrease in the accuracy of reaction to a moving object by three times (p < 0.05). The latent period of simple sensorimotor reaction in emotionally labile subjects after the exercise was increased by 15% (p < 0.05), and the reaction time on a moving object was increased by 8.9% (p < 0.05) as compared with the group of emotionally stable subjects. Thus, the data suggest that changes in the functional state of operators depends on the level of extraversion, personal anxiety, and emotional lability, and does not depend on the level of behavioral regulation, which must be taken into consideration during the assessment of functional state.     

Explicit and Implicit Emotional Expression in Bulimia Nervosa in the Acute State and after Recovery

Expression of emotional state is considered to be a core facet of an individual''s emotional competence. Emotional processing in BN has not been often studied and has not been considered from a broad perspective. This study aimed at examining the implicit and explicit emotional expression in BN patients, in the acute state and after recovery. Sixty-three female participants were included: 22 BN, 22 recovered BN (R-BN), and 19 healthy controls (HC). The clinical cases were drawn from consecutive admissions and diagnosed according to DSM-IV-TR diagnostic criteria. Self reported (explicit) emotional expression was measured with State-Trait Anger Expression Inventory-2, State-Trait Anxiety Inventory, and Symptom Check List-90 items-Revised. Emotional facial expression (implicit) was recorded by means of an integrated camera (by detecting Facial Feature Tracking), during a 20 minutes therapeutic video game. In the acute illness explicit emotional expression [anxiety (p<0.001) and anger (p<0.05)] was increased. In the recovered group this was decreased to an intermediate level between the acute illness and healthy controls [anxiety (p<0.001) and anger (p<0.05)]. In the implicit measurement of emotional expression patients with acute BN expressed more joy (p<0.001) and less anger (p<0.001) than both healthy controls and those in the recovered group. These findings suggest that there are differences in the implicit and explicit emotional processing in BN, which is significantly reduced after recovery, suggesting an improvement in emotional regulation.     

Smelling chemosensory signals of males in anxious versus nonanxious condition increases state anxiety of female subjects

The hypothesis of this experiment was that humans in an anxious state compared with a nonanxious state are able to increase anxiety levels in other humans via their body odors. Specifically, we hypothesized that male chemosensory anxiety signals compared with neutral chemosignals increase state anxiety of female subjects. Thirteen male subjects participated in 2 different sweat donation sessions: chemosignals were collected during participation in a high rope course (anxiety condition) and in an ergometer workout (neutral condition). State and trait anxiety were evaluated in 20 female odor recipients using Spielberger's state-trait anxiety inventory in a double-blind design. Comparison of state anxiety of odor donors between control and anxiety condition differed significantly indicating that our model of anxiety induction successfully led to the expected change in emotion. Comparison of state anxiety of odor recipients showed a trend toward higher state anxiety in the anxiety condition compared with the neutral condition after 5 min of odor exposure. After 20 min of odor exposure, state anxiety of female subjects was significantly higher during the perception of sweat collected during the anxiety condition in comparison with the perception of sweat collected during the neutral condition. This experiment gives evidence that male anxiety chemosignals compared with neutral chemosignals are capable of inducing an increased state anxiety in female subjects.     

Psychophysiological indexes of recognition of emotions in speech

A review of experimental and theoretical works upon perception of emotions in speech is introduced. The main approaches to experimental study and different types of stimulation are considered. Clinical research and experiments upon healthy subjects investigate the brain organization of emotional speech recognition. In the works by Rusalova, Kislova integral psychophysiological preconditions for the successfulness of the recognition of speech emotional expression were studied. As a result of the investigation, extreme groups of persons were identified: with high indices of "emotional hearing" and with low level of recognition of emotions. Analysis of EEG included comparison of different EEG parameters between two groups: values of EEG power, the dominating frequencies, percentage of different EEG-bands in the summary EEG power, coherence, values of EEG inter- and intra-hemispheric asymmetry, etc. The subjects with low identification rates showed a higher brain activation and reactivity both during the emotion identification task and at rest as compared to the subjects with high identification rates. The data obtained reveal specific activation within the left frontal regions, as well as the right posterior temporal cortex during nonverbal recognition of emotions.     

Implicit Processing of Visual Emotions Is Affected by Sound-Induced Affective States and Individual Affective Traits

The ability to recognize emotions contained in facial expressions are affected by both affective traits and states and varies widely between individuals. While affective traits are stable in time, affective states can be regulated more rapidly by environmental stimuli, such as music, that indirectly modulate the brain state. Here, we tested whether a relaxing or irritating sound environment affects implicit processing of facial expressions. Moreover, we investigated whether and how individual traits of anxiety and emotional control interact with this process. 32 healthy subjects performed an implicit emotion processing task (presented to subjects as a gender discrimination task) while the sound environment was defined either by a) a therapeutic music sequence (MusiCure), b) a noise sequence or c) silence. Individual changes in mood were sampled before and after the task by a computerized questionnaire. Additionally, emotional control and trait anxiety were assessed in a separate session by paper and pencil questionnaires. Results showed a better mood after the MusiCure condition compared with the other experimental conditions and faster responses to happy faces during MusiCure compared with angry faces during Noise. Moreover, individuals with higher trait anxiety were faster in performing the implicit emotion processing task during MusiCure compared with Silence. These findings suggest that sound-induced affective states are associated with differential responses to angry and happy emotional faces at an implicit stage of processing, and that a relaxing sound environment facilitates the implicit emotional processing in anxious individuals.     

Stress-induced hormonal and mood responses in scuba divers: a field study

The majority of injuries in scuba-divers are attributable to inappropriate behavior under stressful diving conditions, predominantly involving panic reactions emerging from elevated levels of anxiety. Divers with an elevated level of anxiety and poor coping are at higher risk of developing panic reactions than those possessing more adequate stress-coping-mechanisms. In the comparison of two extreme groups of seven divers each with opposite stress coping strategies, prolactin was found to be a hormonal marker with a significant increase in the sub-group of the stress-controllers. This hormonal response was observed in a recreational and a stressful dive, and in the latter with a more distinct elevation. Along with the self-reported emotional conditions under immersion, these data suggest that an increased prolactin level reflects a state of elevated physical and mental activation and vigilance. Facing a stressful situation subjects with more emotional concern and the tendency to surrender react by "blunted responses" and show significantly lower elevations of the prolactin levels in contrast to subjects with the very opposite psychological features. The other observed somatic parameters (epinephrine, norepinephrine) showed significant increases during and after dives (with the exception of saliva cortisol), however without any significant group difference.     

Emotional speech perception unfolding in time: the role of the basal ganglia

The basal ganglia (BG) have repeatedly been linked to emotional speech processing in studies involving patients with neurodegenerative and structural changes of the BG. However, the majority of previous studies did not consider that (i) emotional speech processing entails multiple processing steps, and the possibility that (ii) the BG may engage in one rather than the other of these processing steps. In the present study we investigate three different stages of emotional speech processing (emotional salience detection, meaning-related processing, and identification) in the same patient group to verify whether lesions to the BG affect these stages in a qualitatively different manner. Specifically, we explore early implicit emotional speech processing (probe verification) in an ERP experiment followed by an explicit behavioral emotional recognition task. In both experiments, participants listened to emotional sentences expressing one of four emotions (anger, fear, disgust, happiness) or neutral sentences. In line with previous evidence patients and healthy controls show differentiation of emotional and neutral sentences in the P200 component (emotional salience detection) and a following negative-going brain wave (meaning-related processing). However, the behavioral recognition (identification stage) of emotional sentences was impaired in BG patients, but not in healthy controls. The current data provide further support that the BG are involved in late, explicit rather than early emotional speech processing stages.

Prepartum nausea and vomiting; a new approach to treatment

A controlled study of 101 patients indicated that a combination of amphetamine and Rauwolfia was effective in the treatment of prepartum nausea and vomiting. Good to excellent results were obtained in 53 (83 per cent) of 64 patients who received the combination. Five patients reported fair results; six were not benefited by the treatment. Only five of a control group of 37 patients who received placebos reported good results. In addition to relief of the symptoms of nausea and vomiting, concomitant emotional disturbances, notably anxiety and depression, were alleviated by the drug combination.
