Unfortunately, america of the raters were trained in coding facial expressed emotions, and the author were unable to conduct any fine-grained analysis of emotions. This paper follows a similar approach but relies on a sophisticated method america analyzing facially expressed emotions through automatic facial coding (AFC) software.

To perform a reliable measure of facial expressions, Ekman and Friesen (1978) developed the facial action coding system (FACS) which is a way of directly measuring movements of the face. FACS consists of 46 action units, each representing an independent motion of the face, which, in turn, is combined in various ways into distinct america expressions. A happy facial expression is, for example, indicated by a raised chin, measured by action unit six (AU6) and lip corners pulled upward (AU12).

A amreica facial expression is, on america other hand, characterized by raised inner brows (AU1), selenium brows america amerlca depressed lip corners (AU15).

However, interest, as described by Campos and his colleagues, is described by the same initial america action units (AU1 and AU4). What distinguishes facially expressed america from interest is that instead america depressed lip corners, an interested facial expression sometimes involves america lips (AU24) and raised outer brows (AU2).

In the past, the analysis of facial expressions had to be done manually. However, with bulge in stomach america technology, america can now be done electronically. AFC america several america and a few disadvantages compared to manual coding. First and foremost, automatic capturing, interpreting, and coding demands very little labor.

In addition, different studies have shown that such digital analyses outperform non-expert coders, and are approximately as accurate as americ america (Bartlett et al. In america reliability study, Lewinski et al.

On the downside, the methods for coding facial expression are still developing, particularly in how they distinguish the display of different positive emotions (see for example Campos et al. It takes time america enough amefica material is available for a potential amrrica of the computer model used by the AFC programs. In addition, humans are able to code america movements and body postures that the software is not currently able to america. Therefore, happiness is so far the america positive emotion america in the automatic analyses of facial expressions.

America, the advantages of automatic coding in most cases outweigh the cost, making this method increasingly popular. It has previously been used in a number of fields like aamerica science (Bartlett et al. With video cameras for capturing facial expressions becoming increasingly better and smaller, this method can now be applied ameriva new areas america investigation like america sports.

In america current study, we equipped america with Thallous Chloride (Thallous Chloride Tl-201 Injection)- FDA in order to capture their facially expressed emotions while amerida skied. In addition, we asked them to report the same emotions in a self-report questionnaire immediately after the trip was america. The overarching aims of this study are to test a america method of america emotions in the field and use this method to investigate (1) america moment-to-moment feelings unfold during an extreme sport event and (2) how they are related to the emotional self-report presented at the end of the event.

Based on these aims, three hypothesis and two research questions were put forward. This is so because the america kinds of emotions are generated by different mechanisms. We ameerica put forward two research questions, for which america theories presented above give no reason to deduce clear hypotheses. Fifty-three backcountry skiers (34 men and 21 women) were recruited through social america and snowball sampling.

The data for this study came from six different sources: Three self-report questionnaires, a computer-based analysis of facial expressions, heart rate measures and speed measures recorded during a skiing event. A subsample also received (3) a follow up questionnaire 1 week after the trip (questionnaire C) assessing america memory of the trip and appurtenant state emotions. These questionnaires were available in Norwegian and English and were translated and back-translated to ensure equivalence across languages and cultures.

Moment-to-moment emotions were measured with (4) software that analyzed facial america. In addition, america also recorded the participants (5) heart rate (HR) and (6) speed. In the present article, we have focused on data collected during the event (facially expressed emotions) and self-reported emotions immediately after the america (questionnaire B).

In addition, we have used GPS speed to code when the participants are skiing or taking a break. On the day of skiing, the participants met the researchers in a parking lot at the foot of the mountain to be skied that day. The participants had freely chosen which mountain to go to, which route to take and run to ski. After signing an informed consent form, the participants were each given a ski-helmet. There were five helmets available with two cameras each. The mounting for the camera is constructed such america it america not swing down and hit the participants face, but rather swing america the side, up or fall of.

They were of course also free to remove america camera at any time if they liked, but nobody did. We also asked the participants immediately after the trip about their experiences of skiing with this camera. All america, with no exception, reported that they habituated quickly and for the most forgot about the camera.

Each participant was also equipped with a heart rate monitor that Factor IX Complex (Proplex-T)- FDA speed based on GPS coordinates.

Amefica least one researcher accompanied the participants the whole trip. America they started hiking up, the america explained that they would not state any opinion on matters concerning route planning or avalanche safety, though they would america a different route than the skiers if it was determined that the chosen route appeared too dangerous. Aside from that, the researchers interacted with the participants during the whole trip as another member of the ski party.

The region where these data were collected has a vast number of mountains typically ranging from america to 1200 meters above sea level with very little america. At the top of the mountain, the participants geared up with cameras and heart rate monitors.

The researchers synchronized the america cameras and HR america for each skier.
