Speech Prosody in Affective Contexts in Thai Patients with Right Hemisphere Lesions

Lateralization of Prosody during Language Production: A Lesion Study

“…For instance, studies of Thai indicate that while left hemisphere patients show deficits in linguistic prosodic tasks, patients with right-hemisphere damage exhibit a preserved capability for the processing of F0 and time structure information (Gandour, Ponglorpisit, & Dardarananda, 1992;Gandour, Dechongkit, Ponglorpisit, & Khunadorn, 1994). Right-hemisphere-damaged patients, however, show deficits when the task focuses on affective aspects of language processing (Gandour, Larsen, Dechongkit, Ponglorpisit, & Khunadorn, 1995). Taken together, these and other findings suggest a lateralization of prosody that depends on function (Van Lancker, 1980).…”

Gender and the Integration of Acoustic Dimensions of Prosody: Implications for Clinical Studies

“…Previous investigators of the neurological control of prosody through acoustic analysis have examined temporal and spectral dimensions in isolation from each other (Emmorey, 1987;Ryalls et al, 1987;Behrens, 1988;Hird & Kirsner, 1993;Hertrich & Ackermann, 1993;Hird, 1993;Gandour et al, 1995;Dykstra et al, 1995;Ouellette & Baum, 1993;Balan & Gandour, 1999). However, with the expected variation in speaking rates, mean F 0 , and F 0 range between subjects, large study groups may be required to highlight any existing anomalies before unequivocal claims regarding the neurological control of individual acoustic parameters can be made from speech production studies.…”

“…Over the past decade there has been an increased interest in determining the neurological control of prosody through objective acoustic analysis of speech productions from brain-damaged subjects (Emmorey, 1987;Ryalls et al, 1987;Behrens, 1988;Hird & Kirsner, 1993;Hertrich & Ackermann, 1993;Hird, 1993;Gandour et al, 1995;Dykstra et al, 1995;Ouellette & Baum, 1993;Balan & Gandour, 1999). To date no agreement has been reached on the topic, but the prevailing hypotheses are that affective prosody is controlled by the right hemisphere while linguistic prosody is a function of the left hemisphere (Van Lancker, 1980); individual acoustic cues are independently lateralized, with the right hemisphere being responsible for fundamental frequency and the left controlling durational cues (Van Lancker & Sidtis, 1992); and the length of the utterance determines which hemisphere is in control, with the left directing phonemic and lexical level prosody while sentence level is the realm of the right hemisphere (Balan & Gandour, 1999).…”

Affective auditory stimuli: Characterization of the International Affective Digitized Sounds (IADS) by discrete emotional categories

“…The most compelling of these is a study by Scott et al (1997) that describes a brain damaged patient who shows impaired responses on emotional recognition tasks using sounds and prosody, but only when the stimuli were angry or fearful, not when they were happy, sad, or disgusting. Many other studies have shown brain damage or lesion patients to have altered perception of emotional sounds, such as prosody (Adolphs, Damasio, & Tranel, 2002;Adolphs, Tranel, & Damasio, 2001;Baum & Dwivedi, 2003;Gandour, Larsen, Dechongkit, Ponglorpisit, & Khunadorn, 1995;Kujala, Lepist6, Nieminen-von Wendt, Näätänen, & Näätiinen, 2005) and music (Gosselin, Peretz, Johnsen, & Adolphs, 2007). Likewise, it has been shown that virtual lesions created by repetitive transcranial mag -n e t i c s t i m u l a t i o n ( T M S ) c a n s e l e c t i v e l y i m p a i r r e c o g n i t i o n of withdrawal emotions, such as fear and sadness, while leaving responses to approach emotions, such as happiness and anger, unaltered (van Rijn et al, 2005).…”
