1. 1. Processing of task-irrelevant sounds while performing a visual task : A study of auditory steady-state evoked potentials

   University essay from Stockholms universitet/Psykologiska institutionen

   Author : Jenny Arctaedius; [2020]
   Keywords : Attention; Auditory Processing; Perceptual load; ASSRs; Filtering; EEG;

   Abstract : Perceptual capacity and selection in attention have for long been an interest in cognitive science, with early theories of early selection to late selection. Hearing is an important subject to investigate when it comes to attention and early auditory processing can be investigated by using auditory steady state responses (ASSRs). READ MORE

3. 2. An ROI-analysis of Activation in FG2, Amygdala lb and dlPFC : How are they Functionally Organized in a Face Working Memory task

   University essay from Linköpings universitet/Psykologi

   Author : Jonathan Mira; Kalle Österman; [2020]
   Keywords : Functional Magnetic Resonance Imaging; ROI-analysis; Face Working Memory; n-back; FG2; Amygdala lb; dlPFC;

   Abstract : Working memory (WM) for facial identity and WM for facial expressions of emotions is important in everyday functioning and seems to have different neurobiological correlates. We investigated the level of neural activation in three regions of interest (ROI): the fusiform face area (FFA), dorsolateral prefrontal cortex (dlPFC), and amygdala; and how they are related to behavioral performance during an n-back task involving face stimuli with a complex background figure within an fMRI-paradigm.

4. 3. Effect of Visual Load on Auditory Steady-State Response and Subjective Workload

   University essay from Stockholms universitet/Psykologiska institutionen

   Author : Sandra Challma; [2019]
   Keywords : EEG; ASSR; Workload;

   Abstract : Attention can be directed to different modalities such as vision and hearing. Crossmodal attention perspective consider the distribution of simultaneous attention through different senses. It is unclear to which degree task-irrelevant sounds are processed during crossmodal attention. READ MORE

5. 4. Does working memory capacity correlate with processing of auditory distractors under low versus high visual load?

   University essay from Stockholms universitet/Psykologiska institutionen

   Author : Rasmus Skarp; [2018]
   Keywords : working memory capacity; perceptual load; processing; ASSR; auditory steady state responses; EEG;

   Abstract : Individuals with high working memory capacity (WMC) appear to be particularly good at focusing their attention (McCabe, Roediger, McDaniel, Balota, & Hambrick, 2010). Therefore, we studied the correlation between WMC and the ability to suppress neurological activity from a task-irrelevant stimulus. READ MORE

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

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

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

   Abstract : 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.
