When the pupil dilates, amount of light that falls onto retina increases. However, in daily life, this does not make world look brighter. Here we asked whether size (resulting from active movement) influences subjective brightness absence indirect cues that, support constancy. We measured a tester stimulus relative to referent as function during presentation. In Experiment 1, manipulated through secondary working-memory task (larger pupils with higher load and after errors). found some...

Response inhibition is key to flexible behavior. Importantly, performance in any task, including response tasks, fluctuates on a moment-to-moment basis. Using pupillometry, we investigated the relationship between these behavioral fluctuations and naturally-occurring of norepinephrine (NE) levels brain before given trial has even started. This was motivated by earlier pharmacological work suggesting pivotal role NE inhibition, particular. We specifically used two pupillometry proxies for...

Nicotine has been commonly used in pyschopharmacological studies, showing its benefits as a pharmacological stimulant on cognitive performance. In the current study, we investigated effects of 2 mg (Experiment 1) and 4 2) nicotine performance multiple-object-tracking task. Participants were young non-smoking adults with no pre-existing attentional deficits. placebo administered through nicotine- free taste-matched chewing gum, respectively. Additionally, compared pupil size between...

The present study investigated the effect of background luminance on self-reported valence ratings auditory stimuli, as suggested by some earlier work. A secondary aim was to better characterise pupillary responses, which literature is inconsistent. Participants were randomly presented with sounds different categories (negative, neutral, and positive) obtained from IADS-E database. At same time, computer screen (in blue hue) manipulated across three levels (i.e., low, medium, high),...

ABSTRACT This research aims to analyze the effectiveness of YouTube-based videos as a media in learning daily English conversation for children and identify factors affecting by using media. To obtain aims, this uses six whose ages vary from ten twelve years old lived Asrama Yatim Mizan Amanah located at Jalan Salihara, Pasar Minggu, South Jakarta source data. Descriptive qualitative method is applied design. In collecting data, researchers gather result activities pre-tests, treatments,...
