Why does the intervention sound different

The above results indicate that the facial expressions of elderly with dementia are affected by the number of intervention days for two of the three sound sources. Therefore, in studying how sound interventions affect the mood of older people with dementia, the number of days of the intervention should be considered.

Changes in valence over 5 days of experiment for different sound interventions. A music, B stream, C birdsong. In a field experiment studying the emotions of elderly with dementia, various factors may affect the facial expressions of the participant, such as vision, smell, and the mood of the care partner.

This makes it somewhat difficult to recognize emotions through only facial expressions. Acknowledging this limitation, the aim of this research was to verify the effectiveness of FER in emotion recognition for older people with dementia. This study proposes FaceReader as a potential method for evaluating the impact of sound interventions on emotions in older people with dementia.

Through field experiments with 35 participants, the following conclusions were drawn. First, FaceReader can identify differences in the emotional responses of older people with dementia using different types of sound interventions. Among the three sound sources, music showed the most positive effects on the mood of older adults with dementia. The effects of music, birdsong, and the sound of a stream were higher than that with no sound source. The facial expression indices of sadness, fear, and disgust also differed significantly between sound sources, while happiness, surprise, and anger did not.

Second, the sound and activity started simultaneously had a more positive influence on the mood of older adults with dementia than when playing the sound before the activity started, especially under the intervention of music and streams.

Regarding intervention days, only music and stream sound showed significant differences in the effect between different dates. Birdsong also had differences in effect, but those differences were not significant. This shows that, when using FaceReader to measure the impact of sound interventions on emotions in elderly with dementia, more than one intervention must be performed to obtain accurate and reliable results.

The comparison of results from FaceReader and the subjective evaluation scale shows that facial expression valence can predict pleasure, arousal, dominance, and acoustic comfort.

In terms of gender, the sound of a stream more easily elevated the emotions in women than in men. In terms of age, only under the intervention of music and stream sound was age related to the emotions of older adults with dementia. Regardless of the sound source, no correlations were found between facial expression valence and MMSE scores. Ethical review and approval was not required for the study on human participants in accordance with the local legislation and institutional requirements.

Re, S. Facial expression in severe dementia. The Intervention is available at level 4, when Create-A-Class is unlocked. The rifle has a low fire rate and high sway, but has high damage multipliers with varying levels of recoil.

Extended Magazines doubles its five round capacity, which is the lowest of all primary weapons. With Stopping Power , the weapon kills in one hit to the head, neck, chest and stomach.

Without it, it loses the one shot kill to the stomach. Targets will require multiple hits when Painkiller , Last Stand or Final Stand is used, or when firing through cover.

However, headshots cancel out Last and Final Stand. With a Silencer , Stopping Power is required for a one-shot-kill. The Intervention is able to get one-shot-kills if the player hits the head, neck or chest. In Hardcore , the weapon will always neutralize targets in one shot anywhere in the body, with or without Stopping Power, regardless of attachments, again unless Last Stand is used by enemies or when firing through cover.

Due to this fact, other sniper rifles are recommended, as the Intervention's low rate of fire lets it down as other rifles can attain one hit kills while having higher rates of fire and lower recoil as well as higher magazine capacities.

The rifle is one of the best suited sniper rifles for attaining the "Perfectionist" challenge due to its low magazine capacity. The WA can be better suited for this task, as it boasts lower recoil, lower damage meaning follow-up shots can be done faster , higher fire rate and lower idle sway and one extra bullet when compared to the Intervention.

The Intervention has a very quick Reload Cancel when reloading an empty magazine - its ammo counter is filled almost as soon as the magazine is taken out. The Intervention is statistically outclassed by the Barrett. Though the Barrett. Because of what the Create-A-Class statistics state, some players believe the Intervention is more accurate than the Barrett, but this is not true; the center of the scope's cross-hairs of every sniper rifle is always where the shot will land, and the higher accuracy is only for the lower recoil.

Despite its drawbacks, the Intervention is one of the most popular sniper rifles online because of its bolt-action nature, which can be more exciting to use than a semi-automatic, and is the weapon of choice among rushing snipers and 'quick-scopers'. Also, the Intervention is very popularly used in montages, as it is believed to require more skill to use, due to its bolt-action nature. This weapon is also very commonly found with the FMJ attachment, mostly because of the popular belief that FMJ adds damage on other players, though this is untrue; it only reduces damage lost when shots are fired through objects, such as wood and metal.

Without FMJ, even with Stopping Power one-shot-kills through cover are entirely impossible unless the opponent was already injured - even if the shot was penetrated through thin glass. However, with said perk and attachment, the player will have one-shot-kill potential to the head, neck and chest.

Sometimes it is attached with an ACOG Scope , making it an assault-type sniper rifle, giving the user peripheral vision at the cost of decreased zoom and the inability to steady the rifle, although the M14 EBR would be a better weapon when equipped with an ACOG, having less recoil, higher magazine capacity, lower reload time, lower sway, and higher rate of fire.

However, unlike the Call of Duty: Modern Warfare 2 version, it now has a 6 round magazine instead of 5. Who remembers when I thought I was the best sniper on this board? How can you and a friend join the same public Match from different machines?
