1. 11. Processing affective information after sleep loss

   Författare :Andreas Gerhardsson; Håkan Fischer; Johanna Schwarz; Daniel Lundqvist; Philippe Peigneux; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sleep deprivation; sleep restriction; affective bias; emotional working memory; positivity effect; sömnbrist; sömnrestriktion; emotionellt bias; arbetsminne; positivitetseffekten; psykologi; Psychology;

   Sammanfattning : It is not fully understood why we need to sleep, although it is evident that sleep loss has consequences for many emotional and cognitive functions. The last couple of decades, sleep researchers have been increasingly devoted to better understand the relationship between sleep and affect. LÄS MER

3. 12. Lost in Translation : Speech recognition and memory processes in native and non-native language perception

   Författare :Lisa Kilman; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Speech perception; perceived disturbance; native; non-native; working memory; language proficiency; episodic long-term memory; Taluppfattning; upplevd störning; modersmål; ett andra språk; arbetsminne; språkfärdigheter; episodiskt långtids-minne;

   Sammanfattning : This thesis employed an integrated approach and investigated intra- and inter-individual differences relevant for normally hearing (NH) and hearing-impaired (HI) adults in native (Swedish) and non-native (English) languages in adverse listening conditions. The integrated approach encompassed the role of cognition as a focal point of interest as well as perceptualauditory and linguistic factors. LÄS MER

4. 13. Cognition Seen Through the Eyes of Hearing Aid Users : Working Memory Resource Allocation for Speech Perception and Recall

   Författare :Andreea Micula; Jerker Rönnberg; Elaine Hoi Ning Ng; Piers Dawes; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Working memory; Free recall; Pupillary responses; Noise reduction; Arbetsminne; Återgivning; Pupillmätning; Brusreducering;

   Sammanfattning : This thesis investigates how hearing aid users allocate working (WM) memory resources under various task demands when listening to and storing speech in memory for later recall. This was done by combining an auditory recall task, the Sentence-final Word Identification and Recall (SWIR) test, with pupillometry. LÄS MER

5. 14. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

   Författare :Sushmit Mishra; Mary Rudner; Stefan Stenfelt; Jerker Rönnberg; Thomas Lunner; Mithell S. Sommers; Linköpings universitet; []
   Nyckelord :Working memory; cognitive spare capacity; updating; inhibition; Arbetsminne; kognitiv reservkapacitet; uppdatering; inhibition;

   Sammanfattning : Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

7. 15. Cognition in Hearing Aid Users : Memory for Everyday Speech

   Författare :Hoi Ning Elaine Ng; Jerker Rönnberg; Mary Rudner; Thomas Lunner; Kevin Munro; Linköpings universitet; []
   Nyckelord :Hearing aid; working memory; free recall; noise reduction; speech recognition; Hörapparat; arbetsminne; återgivning; brusreducering; taluppfattning;

   Sammanfattning : The thesis investigated the importance of cognition for speech understanding in experienced and new hearing aid users. The aims were 1) to develop a cognitive test (Sentence-final Word Identification and Recall, or SWIR test) to measure the effects of a noise reduction algorithm on processing of highly intelligible speech (everyday sentences); 2) to investigate, using the SWIR test, whether hearing aid signal processing would affect memory for heard speech in experienced hearing aid users; 3) to test whether the effects of signal processing on the ability to recall speech would interact with background noise and individual differences in working memory capacity; 4) to explore the potential clinical application of the SWIR test; and 5) to examine the relationship between cognition and speech recognition in noise in new users over the first six months of hearing aid use.
