Facial expressions of basic emotions have been widely used to investigate the neural substrates of emotion processing, but little is known about the exact meaning of subjective changes provoked by perceiving facial expressions. Our assumption was that fearful faces would be related to the processing of potential threats, whereas angry faces would be related to the processing of proximal threats...

Attention is believed to be biased toward threatening objects or faces. Therefore, we tested whether angry face stimuli would capture attention even when they are irrelevant to the task. Observers searched for a neutral face with a tilted nose. On some trials, the target was shown together with an irrelevant angry or happy face and we measured the N2pc (an electrophysiological marker of attenti...

INTRODUCTION Vocal anger is a salient social signal serving adaptive functions in typical child development. Despite recent advances in the developmental neuroscience of emotion processing with regard to visual stimuli, little remains known about the neural correlates of vocal anger processing in childhood. This study represents the first attempt to isolate a neural marker of vocal anger proces...

Social phobia has been associated with abnormal processing of angry faces, which directly signal disapproval--a situation that social phobics fear. This study investigated the electrophysiological correlates of emotional face processing in socially phobic and non-phobic individuals. Subjects identified either the gender (modified emotional Stroop task) or the expression of angry, happy, or neut...

BACKGROUND Recently, emotion recognition has become a hot topic in human-computer interaction. If computers could understand human emotions, they could interact better with their users. This paper proposes a novel method to recognize human emotions (neutral, happy, and angry) using a smart bracelet with built-in accelerometer. METHODS In this study, a total of 123 participants were instructed...

An experiment employing a factorial arrangement of three levels (0, 8 and 16%) of canola meal (CM), two levels (0.15 and 0.25%) of nonphytate phosphorus (NPP), and two levels (0 and 450 unit/kg; as fed basis) of microbial phytase was conducted using 216 Hy-Line W36 laying hens from 39 to 47 weeks of age. The birds receiving CM consumed more (P < 0.05) feed than birds receiving corn-soybean meal...

The Kapiti and D’Urville Islands populations of little spotted kiwi (Apteryx owenii) are the only two long-standing populations of this species that have survived the decline of kiwi in the 20th century. The populations were compared to determine their conservation status and to provide a basis for management decisions for the two surviving birds from D’Urville Island. Measurements, voice, ecto...

I. Chicks were reared in germ-free and conventional environments on diets devoid of one of each of the following vitamins: riboflavine, pantothenic acid, vitamin Be, vitamin B,,, folic acid, nicotinic acid, thiamine or biotin. When marked signs of deficiency began to appear the birds were killed. The livers and caecal contents were removed and assayed microbiologically for the vitamin omitted f...
