Aversion-related changes in the call structure of Squirrel monkey vocalizations
No full textIt is generally assumed that the variation in primate calls is, to a certain extent, correlated with the internal state of a caller. However, it remains difficult to describe this relationship because it is difficult to get reliable information of the internal state of a caller. Therefore, the vocalizations given by Squirrel monkeys were analyzed in a self‐stimulation study done by Uwe Jürgens (1978). In this study it was measured how certain intracerebral stimulations were experienced by the subject. The Squirrel monkeys were in a cage with two compartments. Presence in one compartment was followed by a stimulation, whereas presence in the other compartment was stimulus free. As the animals were free to move from one compartment to the other, they could decide whether they wanted to avoid the stimulus or not. The multiparametric analysis revealed significant correlations between call parameters and the degree of aversion. Whereas single call types showed partly different parameter correlations, a shift in call pitch was found for all call types. In other words, the more intense the aversion was, the higher the frequency parameters (e.g., peak frequency or frequency range) were. =2
Responses of Redfronted Lemurs to Experimentally Modified Alarm Calls: Evidence for Urgency‐Based Changes in Call Structure
No full textThe aim of this study was to investigate how information about the affective state is expressed in vocalizations. Alarm calls can serve as model systems with which to study this general question. Therefore, we examined the information content of terrestrial predator alarm calls of redfronted lemurs (Eulemur fulvus rufus), group-living Malagasy primates. Redfronted lemurs give specific alarm calls only towards raptors, whereas calls given in response to terrestrial predators (woofs) are also used in other situations characterized by high arousal. Woofs may therefore have the potential to express the perceived risk of a given threat. In order to examine whether different levels of arousal are expressed in call structure, we analysed woofs given during inter-group encounters or in response to playbacks of a barking dog, assuming that animals engaged in inter-group encounters experience higher arousal than during the playbacks of dog barks. A multivariate acoustic analysis revealed that calls given during group encounters were characterized by higher frequencies than calls given in response to playbacks of dog barks. In order to examine whether this change in call structure is salient to conspecifics, we conducted playback experiments with woofs, modified in either amplitude or frequencies. Playbacks of calls with increased frequency or amplitude elicited a longer orienting response, suggesting that different levels of arousal are expressed in call structure and provide meaningful information for listeners. In conclusion, the results of our study indicate that the information about the sender's affective state is expressed in the structure of vocalizations
Responses of squirrel monkeys to their experimentally modified mobbing calls
No full textPrevious acoustic analyses suggested emotion-correlated changes in the acoustic structure of squirrel monkey (Saimiri sciureus) vocalizations. Specifically, calls given in aversive contexts were characterized by an upward shift in frequencies, often accompanied by an increase in amplitude. In order to test whether changes in frequencies or amplitude are indeed relevant for conspecific listeners, playback experiments were conducted in which either frequencies or amplitude of mobbing calls were modified. Latency and first orienting response were measured in playback experiments with six adult squirrel monkeys. After broadcasting yaps with increased frequencies or amplitude, squirrel monkeys showed a longer orienting response towards the speaker than after the corresponding control stimuli. Furthermore, after broadcasting yaps with decreased frequencies or amplitude, squirrel monkeys showed a shorter orienting response towards the speaker than after the corresponding manipulated calls with higher frequencies or amplitude. These results suggest that changes in frequencies or amplitude were perceived by squirrel monkeys, indicating that the relationship between call structure and the underlying affective state of the caller agreed with the listener’s assessment of the calls. However, a simultaneous increase in frequencies and amplitude did not lead to an enhanced response, compared to each single parameter. Thus, from the receiver’s perspective, both call parameters may mutually replace each other
Políticas de la mirada : Identidades y territorios en pugna en Gerónima (1986) y La nave de los locos (1994)
No full textLa relación entre cine y realidad está mediada por la experiencia de la imagen/sonido, ya que esta forma parte del campo de batalla por el sentido. Así, "[r]econocerlo, criticarlo, intentar conocerlo con la mayor precisión posible: esa sea tal vez una primera responsabilidad política cuyos riesgos deben asumir con paciencia el historiador, el filósofo o el artista" (DidiHuberman 2014: 19). Inscribimos la interrogación que da origen a este artículo en la noción de hegemonía cultural, ya que, como el resto de las prácticas culturales, la cinematográfica puede pensarse en términos de lo que Williams (1980) distinguió como dominante, residual y emergente para pensar la convivencia en el tiempo de discursos heterogéneos asociados a diferentes proyecciones sobre la organización social, que implican disputas en torno a las memorias e identidades de los pueblos.Fil: Escobar, María de la Paz.

ARCOSUR Vortragsreihe „Argentinien und Chile im interdisziplinären Fokus“ (Sommersemester 2016)
No full textEl Centro Internacional de Estudios Interdisciplinarios Argentina / Cono Sur -ARCOSUR- de la Friedrich Schiller Universität Jena surge en 2015 por la iniciativa de la Prof. Dra. Claudia Hammerschmidt, como un espacio para estudios interdisciplinarios desde un concepto innovador intra e interterritorial y, a su vez, intra e interinstitucional.
La visión de ARCOSUR es rescatar saberes de diversos actores sociales y económicos, construir puentes entre territorios cercanos y distantes, y conectar mediante redes a los actores académicos con los actores del entramado socio económico de esos territorios.
La misión de ARCOSUR es promover proyectos de investigación transnacionales, que partiendo de un concepto de innovación social, tengan como objetivo la transferencia de conocimientos tanto al mundo de las instituciones sociales como hacia el mundo de las empresas
