As is stressed by Ohala and Feder [37] and summarized by, for example, Kleber et al. [40], sound changes can occur despite a "subtraction mechanism" due to a misalignment between the production and perception of variation [85].
This could add to the perception of variation and result in a higher level of appreciation.
Pedestrians' perception of variation of temperature differs between those in the northern Sweden and those in the central and southern Sweden.
Information was also collected during informal conversation and by asking direct questions referring mainly to the motivation of the respondents for cultivating palms on their land, their perception of variation, their preference of palm traits and their management practices.
Perception of variations in environmental as well as internal developmental cues, transduction and amplification of signals and activation of the response to stimuli is crucial for survival, optimal growth and development.
Perception of variations in auxin homeostasis and downstream signaling events has been analyzed extensively in the model plant Arabidopsis, which led to establishment of pathways specifically required for the transmission of hormonal signals (Boer et al., 2014; Dharmasiri et al., 2005; Kepinski and Leyser, 2005; Paciorek et al., 2005; Ulmasov et al., 1999; Xu et al., 2010).
Perceptions of variation within and among Paleolithic assemblages are strongly biased in favor of the most common or most "important" technological variants.
These findings may also reflect differences in the perception of risk, variation in the likelihood of injury, and gender differentials in care-seeking by parents (Morrongiello and Rennie 1998; National Federation of High Schools 2016).
These findings stress the importance of perception of temporal variation in understanding speech information.
While single cones are used for chromatic tasks in birds, perception of achromatic variation is believed to be mediated by the double cones [ 67].
It is desired for such algorithms to maintain a consistent perception of a scene regardless of illumination variation.
