Cortical Processing of Distracting Speech in Noisy Auditory Scenes Depends on Perceptual Demand
No full textSelective attention is essential for the processing of multi-speaker auditory scenes because they require the perceptual segregation of the relevant speech (‘target’) from irrelevant speech (‘distractors’). For simple sounds, it has been suggested that the processing of multiple distractor sounds depends on bottom-up factors affecting task performance. However, it remains unclear whether such dependency applies to naturalistic multi-speaker auditory scenes. In this study, we tested the hypothesis that increased perceptual demand (the processing requirement posed by the scene to separate the target speech) reduces the cortical processing of distractor speech thus decreasing their perceptual segregation. Human participants were presented with auditory scenes including three speakers and asked to selectively attend to one speaker while their EEG was acquired. The perceptual demand of this selective listening task was varied by introducing an auditory cue (interaural time differences, ITDs) for segregating the target from the distractor speakers, while acoustic differences between the distractors were matched in ITD and loudness. We obtained a quantitative measure of the cortical segregation of distractor speakers by assessing the difference in how accurately speech-envelope following EEG responses could be predicted by models of averaged distractor speech versus models of individual distractor speech. In agreement with our hypothesis, results show that interaural segregation cues led to improved behavioral word-recognition performance and stronger cortical segregation of the distractor speakers. The neural effect was strongest in the δ-band and at early delays (0-200ms). Our results indicate that during low perceptual demand, the human cortex represents individual distractor speech signals as more segregated. This suggests that, in addition to purely acoustical properties, the cortical processing of distractor speakers depends on factors like perceptual demand

Data from: Acoustic and higher-level representations of naturalistic auditory scenes in human auditory and frontal cortex
No full textThis data set was analysed for the publication "Acoustic and higher-level representations of naturalistic auditory scenes in human auditory and frontal cortex" by Lars Hausfeld, Lars Riecke and Elia Formisano (10.1016/j.neuroimage.2018.02.065). Anatomical and functional MRI was acquired at 7 Tesla and over the course of 3 sessions for each participant. Participants listened to natural auditory scenes consisting of three sound sources: voice, instrument and pure tone. To reveal effects of selective attention, participants were asked to listen to one of the three sources by performing a task. The dataset is arranged as follows: - MRI data for each participant are contained in the participant-specific folders S[participant id]_MRIdata.zip - Information and design, stimulation protocols and sounds are contained in DesignProtocolsSounds.zip - README files contain necessary information on the MRI acquisition, experimental design and the coding of conditions Please note additional information in the original publicatio
Author Functions in Lars Kepler\u27s The Hypnotist: An Analysis
No full textThis paper examines Foucault\u27s notion of the author function as it pertains to Lars Kepler\u27s bestselling 2011 crime thriller, The Hypnotist. Lars Kepler is the pseudonym of a Swedish husband-wife writing duo, making him the perfect subject for analysis centering on illusory notion of the author. This paper will answer these questions: Who is the true author of The Hypnotist? What factors influence the author function of this bestelling novel? And what can The Hypnotist phenomenon tell us about the relationships between authors and their readers? This paper will demonstrate that no literary works may be ascribed to an individual person, and that authors hold no privileged knowledge of the works they produce, because authors cease to be authors the moment pen is lifted from page
”Lärda nyheter” i Peter Hernquists korrespondens till Carl von Linné och Abraham Bäck - med kommentarer och utvikningar
Full text linkI detta Meddelande nr 55 från Veterinärhistoriska museet har författaren - professor emeritus Lars-Erik Appelgren - gjort ett urval av den korrespondens som Peter Hernquist hade med sina mentorer Carl von Linné och Abraham Bäck under sin vistelse i Frankrike, varvid ”Lärda nyheter” varit en ledstjärna för urvalet. Speciellt har breven till Bäck försetts med författarens personliga kommentarer men även kompletterats med faktaupplysningar från andra källor än breven om berörda nyheter. För att underlätta läsningen har dessa kommentarer omgetts med enkelkonturerad och utvikningarna med dubbelkonturerad ram. Lars-Erik Appelgren har inte bara genom sitt veterinärhistoriska författarskap utan också genom att ställa sina fackliga kunskaper och sin eminenta estetiska läggning till förfogande gjort Veterinärhistoriska museet ovärderliga tjänster. Det är med stor glädje jag noterar att region Uppsala nyligen visat sin uppskattning genom att tilldela Lars-Erik sitt Medicinhistoriska stipendium med motiveringen att de vill ”lyfta fram ett viktigt men ofta förbisett område inom medicinhistorien: veterinärmedicinen”. Med de varmaste gratulationer
Interpreting Wage Bargaining Norms
Full text linkFrom the mid-1990s onwards, Swedish wage bargaining has been characterised by informal co-ordination of the wage claims of big unions and bargaining cartels. In particular, it has been understood that the manufacturing sector should lead by first agreeing on a pay increase, whereafter the service sector and public sector unions choose a similar increase. We analyse his setup with two possible theoretical interpretations: (i) the manufacturing sector as a tackelberg leader and (ii) a normative role for the manufacturing sector’s pay increase, upported either by unmodelled social pressure or a modeled loss aversion (envy) of the heltered sector unions. The conclusion of the analysis is that the normative or leading role of one sector – in the Swedish case the manufacturing sector – can potentially bring big benefits for employment and output. Generalising an idea suggested by Lars Calmfors and Anna Larsson, our analysis also generates a rudimentary theory of why the wage increase norm sometimes binds and sometimes not. A comparison of the model predictions and the observed outcomes of the last five wage bargaining rounds in Sweden suggests that the model is generally consistent with the empirical observations: wage moderation and norm observance are stronger when the manufacturing industry’s initial relative wage is low.wage bargaining; bargaining co-ordination

Representation of female characters in the films of Lars von Trier
No full textOslanjajući se na sličnosti u ženskim likovima Lars Von Triera, detektirani su patrijarhalni i religijski obrasci koji su okosnica radnje filmova Lomeći valove, Dogville i Antikrist. Kroz religijsku i patrijarhalnu optiku autor čita Lars Von Triera kao redatelja koji istu optiku kritizira i preispituje u svom stvaralaštvu.Relying on the similarities in Lars von Trier's female characters, patriarchal and religious patterns have been detected that are the backbone of the plot of the films Breaking the Waves, Dogville and the Antichrist. Through religious and patriarchal optics, the author reads Lars Von Trier as a director who criticizes and questions the same optics in his work
