  1. 1. Memory Distortions Induced by Fluency : Behavioural and Electrophysiological Investigations

    Författare :Anne-Cécile Treese; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory distortions; recall-to-reject; celebrity; fluency; emotion; attractiveness; memory control;

    Sammanfattning : The investigation of memory distortions provides insights into how memory normally works. Adopting a cognitive neuroscience perspective, the present thesis aimed at investigating memory distortions and the neural correlates of processes contributing to successful control of memory interference in healthy participants.

  3. 2. Memory Illusions and Memory Attributions : Behavioural and Electrophysiological Data

    Författare :Mikael Johansson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory illusion; false memory; misattribution; episodic memory; neurofysiologi; familiarity; recollection; source monitoring; event-related potentials; Neurology; neuropsychology; neurophysiology; neuropsykologi; Neurologi;

    Sammanfattning : Although memory often serves us well, it can also prove highly unreliable. The study of illusions and distortions of memory unveils important information about the nature of human memory functioning and, moreover, factors affecting memory accuracy. LÄS MER

  4. 3. Behavioral and Electrophysiological Correlates of Inhibition in Episodic Memory

    Författare :Gerd Waldhauser; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory control; inhibition; EEG; ERP; forgetting;

    Sammanfattning : Forgetting can be highly functional when unwanted or irrelevant memory representations interfere with cognitive or motivational goals. Current theory assumes that forgetting can be brought about by the intentional or unintentional inhibition of interfering memory representations. LÄS MER

  5. 4. Human motor control, autonomic and decision processes under physical and psychological stress. Instinctive, reflexive and adaptive aspects

    Författare :Johan Bertilsson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neuroendocrine stress response; Pepper spray; Police officer involved shootings; Memory distortions; Motor control;

    Sammanfattning : The stress response is governed by automatic neurological and hormonal processes that occur before we become consciously aware of a dangerous situation. If stress ensues for 15-30 seconds, the hormonal processes may have progressed so far that recovery takes an hour or longer instead of minutes. LÄS MER

  7. 5. Characterization and Compensation of Hardware Impairments in Transmitters for Wireless Communications

    Författare :Zain Ahmed Khan; Peter Händel; Magnus Isaksson; Mikko Valkama; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power amplifier; RF transmitters; SISO; MIMO; crosstalk; Volterra series; Volterra kernels; behavioral modeling; DPD; Ramanujan sums; multitone signals; I Q Imbalance; non-linearity; memory polynomial; density estimation; hardware impairments; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Increasing demands for data rate, energy efficiency and reliability in wireless communications have resulted in the introduction of radio frequency (RF) multiple input multiple output (MIMO) transmitters. However, MIMO transmitters suffer from additional crosstalk impairments along with the power amplifier (PA) and I/Q imbalance distortions observed in single input single output (SISO) transmitters.
