  1. 1. Fishing for Females Sensory Exploitation in the Swordtail Characin

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mirjam Amcoff; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Mate choice; Courtship; Sensory bias; Plasticity; Corynopoma riisei; Mulitiple signalling; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Mate choice plays an important role in sexual selection and speciation. The evolution of mate choice is intriguing in cases where choosy individuals gain little except for genetic material from the mate and where the trait used as a criterion for the choice is costly to its bearer.

  2. 2. Development of functional asymmetries in young infants A sensory-motor approach

    Detta är en avhandling från Umeå : institutionen för psykologi, Umeå universitet

    Författare :Erik Domellöf; Umeå universitet.; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Laterality; development; handedness; human infant; stepping response; placing response; head turning; arm movement; reaching; kinematic parameters; intralimb coordination; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi;

    Sammanfattning : Human functional laterality, typically involving a right-sided preference in most sensory-motor activities, is still a poorly understood issue. This is perhaps particularly true in terms of what underlying mechanisms that may govern lateral biases, as well as the developmental origins and course of events. LÄS MER

  3. 3. The Role of Odor and Sensory Irritation in Human Chemical Sensitivity

    Detta är en avhandling från Stockholm : Department of Psychology, Stockholm University

    Författare :Li Zheng; Stockholms universitet.; [2010]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Odor and irritation detection; recognition; threshold; choice theory; intensity; chemical sensitivity; threshold; and sensitivity index.; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi; Psychology; psykologi;

    Sammanfattning : The main objective of this thesis is to apply complimentary psychophysical theories and methods to investigate human perception of odor and sensory irritation of chemical compounds present in indoor air. Three psychophysical theories: Signal Detection Theory (SDT), Threshold Theory and Luce’s Choice Theory (CT) were applied to measure detection and recognition of odor and sensory irritation of two odorous irritants (pyridine and formaldehyde) by using the method of constant stimuli.

  4. 4. Hand function in children and in persons with neurological disorders aspects of movement control and evaluation of measurements

    Detta är en avhandling från Umeå : Institutionen för samhällsmedicin och rehabilitering

    Författare :Elisabeth Svensson; Umeå universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebellum; disability; hand function; hereditary motor and sensory neuropathies; latency; motor control; reactive control; reproducibility; sensation; strength; INTERDISCIPLINARY RESEARCH AREAS Caring sciences Physiotherapy; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vårdvetenskap Sjukgymnastik fysioterapi;

    Sammanfattning : Hand function is of great importance in the many daily activities that require well-coordinated hand and arm movements. Measurement of hand function is an essential element in the rehabilitation process, in order to facilitate medical diagnosis and determine developmental stages, functional levels, and the efficacy of treatment interventions.

  5. 5. The functional neuroanatomy of emotion regulation in major depressive disorder

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Författare :Teresa Victor; Karolinska Institutet.; Karolinska Institutet.; [2013]

    Sammanfattning : A mood-congruent processing bias toward negative emotional information is a hallmark characteristic of the pathophysiology of major depressive disorder (MDD). Previous neuropsychological studies have provided evidence of this phenomenon in memory and attention paradigms. LÄS MER
