  1. 1. Cognitive Abilities and their Influence on Speech-In-Noise Information Processing : a Study on Different Kinds of Speech Support and Their Relation to the Human Cognition

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Elin Sjöström; [2017]
    Nyckelord :Cognitive Hearing Science; Speech-In-Noise; Speech perception; Cognitive functions; Top-down processing; Bottom-up processing; TMT; PASAT; LIT; Divided attention; Executive function; Semantic comprehension;

    Sammanfattning : In this paper, top-down and bottom-up processing were studied regarding their effect on speech-in-noise. Three cognitive functions were also studied (divided attention, executive functioning, and semantic comprehension), and the effect they have on the speech processing and on each other. LÄS MER

  2. 2. Visual Attentional Capture Resists Modulation in Singleton Search under Verbal Working Memory Load

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Martin Johansson; [2016]
    Nyckelord :singleton search; visual attention; attentional orienting; selective attention; attentional capture; top - down; bottom - up; verbal working memory; AVGP; trait anxiety;

    Sammanfattning : Visual attentional capture is a form of visual attentional selection that is automatic and involuntary in nature, and is of high adaptive value as it allows visual attention to be oriented in a reflexive manner towards visual information without necessarily being guided by pre-existing knowledge, goals, and plans. According to the load-hypothesis (Lavie & De Fockert, 2005), attentional capture of salient stimuli increases under load on working memory due to disruption of stimulus-processing priorities.

  3. 3. The role of semantic context and attentional resource distribution in semantic comprehension in Swedish pre-schoolers

    Kandidat-uppsats, Stockholms universitet/Institutionen för lingvistik

    Författare :Johanna Renate Schelhaas; [2016]
    Nyckelord :Semantic context; attention; resource distribution; N400; dichotic listening task; preschool children; Swedish; Semantisk kontext; fördelning av hjärnresurser; uppmärksamhet; N400; diktotisk lyssningstest; svenska förskolebarn;

    Sammanfattning : Research on semantic processing focused mainly on isolated units in language, which does not reflect the complexity of language. In order to understand how semantic information is processed in a wider context, the first goal of this thesis was to determine whether Swedish pre-school children are able to comprehend semantic context and if that context is semantically built up over time.

  4. 4. Smaken av en god recension : En studie i hur konsumenters smakupplevelsepåverkas av experters utlåtande

    Kandidat-uppsats, Södertörns högskola/Institutionen för samhällsvetenskaper

    Författare :Conny Berg; [2014]
    Nyckelord :marknadsföring; vin; smaktest; påverkan; opinion former; CIP; consumer information process;

    Sammanfattning : Consumer Information Processing (CIP) handlar om hur vi som konsumenter tar till ossoch påverkas av den information som ständigt omger oss vid en beslutssituation. Ämnethar länge varit i fokus för forskning inom marknadsföring då detta naturligtvisintresserar företagen i hög grad. LÄS MER

  5. 5. Unsupervised Spatio-Temporal Activity Learning and Recognition in a Stream Processing Framework

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystemLinköpings universitet/Tekniska högskolan

    Författare :Mattias Tiger; [2014]
    Nyckelord :Activity learning; Activity recognition; Activity prediction; Unsupervised On-line learning; Artificial Intelligence; Spatio-temporal; Stream processing; Sparse Gaussian process;

    Sammanfattning : Learning to recognize and predict common activities, performed by objects and observed by sensors, is an important and challenging problem related both to artificial intelligence and robotics.In this thesis, the general problem of dynamic adaptive situation awareness is considered and we argue for the need for an on-line bottom-up approach.
