Did depressive symptoms affect recognition of emotional prosody in Parkinson's disease?
Neuropsychiatric Disease and Treatment, 2008
Evaluate the influence of depressive symptoms on the recognition of emotional prosody in Parkinson's disease (PD) patients, and identify types of emotion on spoken sentences. Thirty-five PD patients and 65 normal participants were studied. Dementia was checked with the Mini Mental State Examination, Clinical Dementia Rating scale, and DSM IV. Recognition of emotional prosody was tested by asking subjects to listen to 12 recorded statements with neutral affective content that were read with a strong affective expression. Subjects had to recognize the correct emotion by one of four descriptors (angry, sad, cheerful, and neutral). The Beck Depression Inventory (BDI) was employed to rate depressive symptoms with the cutoff 14. Total ratings of emotions correctly recognized by participants below and above the BDI cutoff were similar among PD patients and normal individuals. PD patients who correctly identified neutral and anger inflections presented higher rates of depressive symptom...
Emotional speech in Parkinson's disease
2008
Patients with Parkinson's disease (PD) tend to speak monotonously with minor modulation of pitch and intensity. The goal of this study was to find out whether these speech changes can be explained mainly by motor impairment, i.e. akinesia and rigidity of the articulatory apparatus, or whether alterations of emotional processing play an additional role. Sixteen patients with mild PD and 16 healthy controls (HC) were compared. Fundamental frequencies (pitch) and intensities (loudness) were determined as (1) maximal upper and lower values achieved in nonemotional speech (phonation capacity), (2) upper and lower values used when speaking "Anna" in emotional intonation (neutral, sad, happy) as requested (pro-duction task), or (3) when imitating a professional speaker (imitation task). Although groups did not significantly differ in their phonation capacity, patients showed a significantly smaller pitch and intensity range than HC in the production task. In the imitation task, however, ranges were again similar. These results suggest that alterations of emotional processing contribute to speech changes in PD, especially regarding emotional prosody, in addition to motor impairment.
Vocal emotion processing in Parkinson's disease: Reduced sensitivity to negative emotions
Brain Research, 2008
To document the impact of Parkinson's disease (PD) on communication and to further clarify the role of the basal ganglia in the processing of emotional speech prosody, this investigation compared how PD patients identify basic emotions from prosody and judge specific affective properties of the same vocal stimuli, such as valence or intensity. Sixteen non-demented adults with PD and 17 healthy control (HC) participants listened to semantically-anomalous pseudo-utterances spoken in seven emotional intonations (anger, disgust, fear, sadness, happiness, pleasant surprise, neutral) and two distinct levels of perceived emotional intensity (high, low). On three separate occasions, participants classified the emotional meaning of the prosody for each utterance (identification task), rated how positive or negative the stimulus sounded (valence rating task), or rated how intense the emotion was expressed by the speaker (intensity rating task). Results indicated that the PD group was significantly impaired relative to the HC group for categorizing emotional prosody and showed a reduced sensitivity to valence, but not intensity, attributes of emotional expressions conveying anger, disgust, and fear. The findings are discussed in light of the possible role of the basal ganglia in the processing of discrete emotions, particularly those associated with negative vigilance, and of how PD may impact on the sequential processing of prosodic expressions.
Decoding emotional prosody in Parkinson’s disease and its potential neuropsychological basis.
Journal of Clinical and Experimental Neuropsychology, 2009
Parkinson’s disease patients may have difficulty decoding prosodic emotion cues. These data suggest that the basal ganglia are involved, but may reflect dorsolateral prefrontal cortex dysfunction. An auditory emotional nback task and cognitive n-back task were administered to 33 patients and 33 older adult controls, as were an auditory emotional Stroop task and cognitive Stroop task. No deficit was observed on the emotion decoding tasks; this did not alter with increased frontal lobe load. However, on the cognitive tasks, patients performed worse than older adult controls, suggesting that cognitive deficits may be more prominent. The impact of frontal lobe dysfunction on prosodic emotion cue decoding may only become apparent once frontal lobe pathology rises above a threshold.
Effect of Parkinson Disease on Emotion Perception Using the Persian Affective Voices Test
Journal of voice : official journal of the Voice Foundation, 2018
Emotion perception plays a major role in proper communication with people in different social interactions. Nonverbal affect bursts can be used to evaluate vocal emotion perception. The present study was a preliminary step to establishing the psychometric properties of the Persian version of the Montreal Affective Voices (MAV) test, as well as to investigate the effect of Parkinson disease (PD) on vocal emotion perception. The short, emotional sound made by pronouncing the vowel "a" in Persian was recorded by 22 actors and actresses to develop the Persian version of the MAV, the Persian Affective Voices (PAV), for emotions of happiness, sadness, pleasure, pain, anger, disgust, fear, surprise, and neutrality. The results of the recordings of five of the actresses and five of the actors who obtained the highest score were used to generate the test. For convergent validity assessment, the correlation between the PAV and a speech prosody comprehension test was examined using a...
Perception of emotional speech in Parkinson's disease
Movement Disorders, 2006
Nonmotor symptoms in Parkinson's disease (PD) involving cognition and emotionality have progressively received attention. The objective of the present study was to investigate recognition of emotional prosody in patients with PD (n = 14) in comparison to healthy control subjects (HC, n = 14). Event-related brain potentials (ERP) were recorded in a modified oddball paradigm under passive listening and active target detection instructions. Results showed a poorer performance of PD patients in classifying emotional prosody. ERP generated by emotional deviants (happy/sad) during passive listening revealed diminished amplitudes of the mismatch-related negativity for sad deviants, indicating an impairment of early preattentive processing of emotional prosody in PD. © 2006 Movement Disorder Society
Recognition of emotions from visual and prosodic cues in Parkinson’s disease
Neurological Sciences, 2008
Objective To assess whether Parkinson Disease (PD) patients are impaired at perceiving emotions from facial and prosodic cues and whether any putative defective performance concerns recognition of a particular emotion. Background Braak et al. [1] demonstrated that in different stages PD pathology involves the nigrostriatal system, the amygdala, and the insular cortex. Discrete brain lesions to these structures can cause selective deficits in recognising facial and prosodic stimuli expressing particular emotions. However, the investigation of facial and prosodic emotional processing in PD patients has lead to conflicting results. Materials and methods We compared 27 cognitively unimpaired PD patients with control subjects by means of the Facial Emotion Recognition Battery and the Emotional Prosody Recognition Battery. Results PD patients were impaired in recognising, selecting, and matching facial affects. In particular, the Facial Emotion Recognition Battery demonstrated a severe impairment in recognising sad and fearful faces. In the Emotional Prosody Recognition Battery PD patients demonstrated a diffuse impairment, including the recognition of emotional and propositional prosody. Conclusions Face emotion processing is impaired in PD patients, with a disproportionate deficit involving fear and sadness. The pattern of face expression processing impairment in PD patients might depend on the regional distribution of the pathology. The widespread involvement of both emotional and propositional prosodic processing parallels the aprosodic characteristics of Parkinsonian speech production.
Psychology of Language and Communication
This study aimed to understand the impact of the prosodic deficit in Parkinson’s disease (PD) on the communicative effectiveness of vocal expression of emotion. Fourteen patients with PD and 13 healthy control subjects (HC) uttered the phrase “non è possible, non ora” (“It is not possible, not now”) six times reading different emotional narrations. Three experts evaluated the PD subjects’ vocal production in terms of their communicative effectiveness. The PD patients were divided into two groups: PD+ (with residual effectiveness) and PD− (with impaired effectiveness). The vocal productions were administered to 30 naïve listeners. They were requested to label the emotion they recognized and to make judgments about their communicative effectiveness. The PD speakers were perceived as less effective than the HC speakers in conveying emotions (especially fear and anger). The PD− group was the most impaired in the expression of emotion, suggesting that speech disorders impact differently ...
Perception of linguistic and emotional prosody in Parkinson's disease - evidence from Slovene
The present study investigated the perception of emotional and linguistic prosodic functions in speakers of Slovene language affected by Parkinson's disease. Eight participants with a diagnosis of Idiopathic Parkinson's disease (PD group) and eight elderly healthy controls (HC), matched for age and years of education, were tested using and identification and a discrimination task for emotional and linguistic prosody. The stimuli for linguistic prosody consisted of sentences uttered as a question or as a statement. The stimuli for emotional prosody consisted of sentences uttered in six different emotional tones: anger, disgust, fear, happiness, sadness and pleasant surprise. Compared to healthy control the overall performance of the PD group was lower in three out of four tasks: linguistic identification, linguistic discrimination, and emotional discrimination. Moreover, the PD group identified less accurately negative emotions, more specifically anger and sadness.
