  1. 1. Driver Interaction : Informal Rules, Irritation and Aggressive Behaviour

    Författare :Gunilla Björklund; Lars Åberg; Ralf Risser; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driver interaction; Informal traffic rules; Driver irritation; Aggressive behaviour; Attributional biases; False consensus; Actor-observer effect; Psykologi; Psychology; Psykologi;

    Sammanfattning : On a daily basis drivers have to share the roads with a great number of other road users. To make the driving task possible every driver has to take the intentions and behaviours of other road users into account. In other words, the road users have to interact with each other. LÄS MER

  3. 2. Sex and violence in lobsters - a smelly business

    Författare :Malin Skog; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dominance; urine signals; recognition; Aggressive behaviours; intermoult mating; sexual dimorphism; European lobster; chemical communication; Homarus gammarus; aesthetasc morphology;

    Sammanfattning : The aim of this thesis was to study the chemical communication involved in aggressive and reproductive behaviours in the European lobster (Homarus gammarus). Both male and female H. gammarus established and maintained dominance, but the sexes used different strategies for dominance maintenance. LÄS MER

  4. 3. Anabolic Androgenic Steroids and the Brain : Studies of Neurochemical and Behavioural Changes Using an Animal Model

  5. 4. The Monoamine Oxidase A Gene and Antisocial Outcomes : An Examination of Genetic, Epigenetic, and Environmental Factors

    Författare :David Checknita; Kent W. Nilsson; Lars Westberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epigenetics; Antisocial; Genotype; Maltreatment;

    Sammanfattning : Background. Antisocial behaviour involves violation of the basic rights of others or social norms or rules. Such behaviours are indexed in diagnoses such as conduct disorder (CD) in adolescence and antisocial personality disorder (ASPD) in adulthood, which are typified by comorbidity with mood, anxiety, and substance misuse disorders.

  7. 5. Genetic Structuring and the Evolution of Lekking Behaviour in the White-bearded Manakin, Manacus manacus

    Författare :Lisa Shorey; David McDonald; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Lek Evolution; Manacus manacus; White-bearded Manakin; Genetic Relatedness; Mating Success; Male Characteristics; Behaviour; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

    Sammanfattning : Genetic structuring is common in natural populations. It is important to identify and consider population structure when studying evolutionary processes. Recently, the discovery of genetic structuring in some lekking bird species has opened up new perspectives on our understanding of the evolution of lek mating systems. LÄS MER
