  1. 21. Operant betingning vid hästträning

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Magdalena Wärn; [2010]
    Keywords : Operant betingning; Hästträning; Positiv förstärkning; Negativ förstärkning; Förstärkare; Klickerträning; Primär förstärkare; Sekundär försträkare; Shejping; Targeting; Utsläckning; Bestraffning; Klicker;

    Abstract : En litteraturstudie inom området för operant betingning vid hästträning har genomförts. Vid operant betingning lär man djuret att svara på signaler genom att använda sig av förstärkningar eller bestraffningar. Den operanta betingningen används ofta inom hästträningen då antingen negativ eller positiv förstärkning tillämpas. READ MORE

  2. 22. Olfactory sensitivity in CD-1 mice for six L- and D amino acids

    University essay from Institutionen för fysik, kemi och biologi

    Author : Helena Wallén; [2010]
    Keywords : Amino acid; Olfaction; CD-1 mice; olfactory receptor genes and sulphur- containing group.;

    Abstract : The olfactory sensitivity of five male CD-1 mice (Mus musculus) for six amino acids was determined using an operant conditioning paradigm. All animals significantly distinguished dilutions as low as 0.01 mM L-cysteine, 3.3 mM L-methionine, 10 mM L-proline, 0. READ MORE

  3. 23. Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Marie Eisersiö; [2010]
    Keywords : etologi; häst; inlärning; tygeltryck; ridning;

    Abstract : This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. READ MORE

  4. 24. Olfactory performance and neuropathology in the Tg6799 strain of Alzheimer’s disease model mice

    University essay from Institutionen för fysik, kemi och biologi

    Author : Hanna Österman; [2010]
    Keywords : 5xFAD; Alzheimer’s disease; amyloid precursor protein; amyloid β; cognitive impairment; olfactory deficit.;

    Abstract : The present study evaluated olfactory and cognitive abilities of the Tg6799 (also called 5xFAD) strain of Alzheimer’s disease (AD) model mice of two different age groups (2-3 and 8-10 months of age), and one group of healthy control mice (9-10 months). Employment of an operant conditioning paradigm using an automated olfactometer, an olfactory habituation/dishabituation test and a spatial learning test with non olfactory cues resulted in data showing that the 5xFAD mice develop olfactory impairments already at 2-3 months of age.

  5. 25. Operant conditioning in a self controlling test with a reinforcement delay in Pygmy Hippos (Hexaprotodon liberiensis)

    University essay from Institutionen för fysik, kemi och biologi

    Author : Laila Nauman; [2010]
    Keywords : ;

    Abstract : The curiosity whether or not animals have the characteristics of long term planning skills is fairly new. Some researchers agree that certain species have a form of episodic-like memory, in the terms of where, when and what. READ MORE
