Honeybees prefer novel insect-pollinated flower shapes over bird-pollinated flower shapes
2019
AbstractPlant–pollinator interactions have a fundamental influence on flower evolution. Flower color signals are frequently tuned to the visual capabilities of important pollinators such as either bees or birds, but far less is known about whether flower shape influences the choices of pollinators. We tested European honeybee Apis mellifera preferences using novel achromatic (gray-scale) images of 12 insect-pollinated and 12 bird-pollinated native Australian flowers in Germany; thus, avoiding influences of color, odor, or prior experience. Independent bees were tested with a number of parameterized images specifically designed to assess preferences for size, shape, brightness, or the number…
Impact of Demographic Differences on Color Preferences in the Interface Design of e-Services in Latvia
2018
In our study, we test users’ color preferences of interfaces of typical electronic services’ (e-services) environment. The motivation of our study is to explore discrepancy between (a) the high degree of availability of e-services in Latvia, and (b) low usage of these e-services among population. We aim to find the regularities regarding color preferences that could be useful in the development of e-services and that could support the rise of the usage of e-services in future. Although there are several reasons why people avoid using e-services (some of them socio-cognitive, some – technological), we would like to focus on a particular aspect – the colors of e-services interface. In particu…
Krāsu un emociju attiecības vizuālajā komunikācijā: dažādu vecumposmu salīdzinoša analīze
2017
Darba tēma ir ‘’Krāsu un emociju attiecības vizuālajā komunikācijā: dažādu vecumposmu salīdzinoša analīze’’. Pētījuma problēma: Vai dažāda vecuma cilvēkiem atšķiras krāsu un emociju uztvere? Mērķis ir noskaidrot kā krāsu un emociju saistība mainās dažāda vecuma cilvēkiem. Darba uzdevumi ir iepazīties ar teoriju, noskaidrot krāsu un emociju saistību atšķirību dažādiem vecumposmiem, izmantojot aptauju un eksperimentu, apkopot datus un izdarīt secinājumus. Teorijā izmantotas trīs teorijas: vizuālās komunikācijas teorija, ekoloģiskās valences teorija, krāsas un emocijas. Metodoloģijā izmantotas trīs metodes: aptauja, kontentanalīze un eksperiments. Apkopojot rezultātus redzams, ka vecuma atšķir…
