Consequences of brain tumour resection on emotion recognition

Emotion processing impairments are common in patients undergoing brain surgery for fronto-temporal tumour resection, with potential consequences on social interactions. However, evidence is controversial concerning side and site of lesions causing such deficits. This study investigates visual and auditory emotion recognition in brain tumour patients with the aim of clarifying which lesion sites are related to impairments in emotion processing from different modalities. Thirty-four patients were evaluated, before and after surgery, on facial expression and emotional prosody recognition; voxel-based lesion–symptom mapping (VLSM) analyses were performed on patients’ post-surgery MRI images. Results showed that patients’ performance decreased after surgery in both visual and auditory modalities, but, in general, recovered 3 months after surgery. In facial expression recognition, left brain-damaged patients showed greater post-surgery deterioration than right brain-damaged ones, whose performance specifically decreased for sadness and fear. VLSM analysis revealed two segregated areas in the left hemisphere accounting for post-surgery scores for happy (fronto-temporo-insular region) and surprised (middle frontal gyrus and inferior fronto-occipital fasciculus) facial expressions. Our findings demonstrate that surgical removal of tumours in the fronto-temporal region produces impairment in facial emotion recognition with an overall recovery at 3 months, suggesting a partially different representation of positive and negative emotions in the left and right hemispheres for visually – but not auditory – presented emotions; moreover, we show that deficits in specific expression recognition are associated with discrete lesion locations.     

Prosody instruction intervention as a means to improved reading comprehension

The relationship between prosody and comprehension, previously demonstrated in K–12 students, was examined in university students enrolled in first‐year writing classes. Students completed the Gray Oral Reading Test‐5 both before and after an expressive reading intervention (ER) or no oral reading instruction (NI). Throughout the semester, the ER students marked an excerpt of text for prosodic signals and read it aloud with a partner. Training and practice in expressive reading led to a significant improvement in the normed Oral Reading Index score. Specifically, ER participants demonstrated improved accuracy, fluency, and reading comprehension in comparison with NI participants. The significant relationship between accuracy and comprehension in the ER condition suggests that expressive reading instruction strengthened student ability to read words accurately and, in turn, comprehend the material better than students in the NI condition. Expressive reading practices are recommended to engage students more deeply with the text.     

语境情绪韵律对新异词汇学习过程的影响

模拟自然学习语境,探讨情绪韵律对具体和抽象词学习的调节作用及其产生原因。被试在高兴、愤怒、中性语境情绪韵律条件下学习抽象和具体词,记录学习过程及测试过程中的行为与脑电反应。结果发现在愤怒韵律背景下学习的抽象词加工的正确率更低、反应时更长;并且诱发了更为显著的脑电成分。表明愤怒韵律对词汇学习尤其是抽象词学习有显著的消极作用。此外,情绪韵律对词汇学习的调节作用是在学习过程中对词汇语义提取及晚期语义整合产生影响而形成的。     

SPEECH EVENTS, LANGUAGE DEVELOPMENT, AND THE CLINICAL SITUATION

Psychoanalysis brings about psychic change by the mediation of speech. This paper reflects upon the significance of the structure and developmental organisation of the speech event as a verbal and non-verbal unit composed of semantically and prosodically encoded messages, interactions and emotional contact between partners. Spoken words communicate semantic meanings and the affects of a given speech event. Words carry personal emotional meanings which are inseparable from their referential significance. Such emotional meanings are very hard to articulate in words. They are conveyed by the ineffable but essential feelings present in their sound and pronunciation. Speech is an intentionally object-related and emotionally engaging social activity resulting from a child having been spoken to early in life by an adult wanting to establish affective verbal contact. The early organisation and later transformation of the structure of the speech event carries private meanings for each person's listening and speaking stance. A refined understanding of the structural and emotional complexities of verbal communicative exchanges during analysis may enhance the analyst's ability to understand the patient'smanner of participation in the analytic process.     

言语情绪韵律加工的时间进程

有关情绪韵律加工的时间进程,现在的研究采用ERP技术在词汇和句子水平上进行探讨：在词汇水平,韵律情绪信息和语义情绪信息都存在自动加工,前者可在300ms内得以识别,受到性别、注意等因素的调节;在句子水平,语义情绪加工可能“制约”韵律情绪加工,二者具有交互作用。未来研究应进一步探索情绪韵律加工的时间进程以及与其他信息加工的相互时间关系等。     

Perceiving speech rhythm in music: Listeners classify instrumental songs according to language of origin

Recent evidence suggests that the musical rhythm of a particular culture may parallel the speech rhythm of that culture’s language (Patel, A. D., & Daniele, J. R. (2003). An empirical comparison of rhythm in language and music. Cognition, 87, B35-B45). The present experiments aimed to determine whether listeners actually perceive such rhythmic differences in a purely musical context (i.e., in instrumental music without words). In Experiment 1a, listeners successfully classified instrumental renditions of French and English songs having highly contrastive rhythmic differences. Experiment 1b replicated this result with the same songs containing rhythmic information only. In Experiments 2a and 2b, listeners successfully classified original and rhythm-only stimuli when language-specific rhythmic differences were less contrastive but more representative of differences found in actual music and speech. These findings indicate that listeners can use rhythmic similarities and differences to classify songs originally composed in two languages having contrasting rhythmic prosody.     

Knock,Knock–Who’s Scared?: The Knockout Game as a Short-lived Crime Problem

ABSTRACT

The “knockout game”--youths assaulting strangers at random with the goal of knocking them unconscious with a single blow—attracted intense attention in the United States for a brief period near the end of 2013. This paper examines the history of a set of claims about similar behaviors preceded that knockout game’s eventual celebrity. It demonstrates the difficulty of successfully constructing a new crime problem; it took decades before a combination of elements—location, the characterization of offenders and victims, an emphasis on technology, and a prominent media venue willing to promote the story—brought these claims to prominence.     

Selective attention to emotional prosody in social anxiety: a dichotic listening study

The majority of evidence on social anxiety (SA)-linked attentional biases to threat comes from research using facial expressions. Emotions are, however, communicated through other channels, such as voice. Despite its importance in the interpretation of social cues, emotional prosody processing in SA has been barely explored. This study investigated whether SA is associated with enhanced processing of task-irrelevant angry prosody. Fifty-three participants with high and low SA performed a dichotic listening task in which pairs of male/female voices were presented, one to each ear, with either the same or different prosody (neutral or angry). Participants were instructed to focus on either the left or right ear and to identify the speaker’s gender in the attended side. Our main results show that, once attended, task-irrelevant angry prosody elicits greater interference than does neutral prosody. Surprisingly, high socially anxious participants were less prone to distraction from attended-angry (compared to attended-neutral) prosody than were low socially anxious individuals. These findings emphasise the importance of examining SA-related biases across modalities.     

Emotional prosody effects on verbal memory in older and younger adults

Prosody, or the way things are said, can modify the meaning of utterances making qualitatively different affective prosodies useful for understanding how auditory affective information is processed and remembered. In this study, we collected behavioral data from 225 younger (M age = 20.8 years, SD = 2.5 years; 119 males) and 225 older adults (M age = 71.6 years, SD = 6.5 years; 119 males) in order to examine age differences in emotional prosody effects on verbal memory. Participants were randomly divided into three subgroups according to different prosody listening conditions (positive, negative, and neutral) and prosody effects on a yes–no recognition memory task were investigated. The results showed how older adults who listened to the story read with a neutral prosody remembered more words than those who listened to the same story with a positive or negative prosody. Younger adults showed no valence effects. Our findings highlighted an age and affective prosody interaction that affects remembering in older adults alone.
