Social anxiety

Summary

Social anxiety is the anxiety and fear specifically linked to being in social settings (i.e., interacting with others). Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations. Some feelings of anxiety in social situations are normal and necessary for effective social functioning and developmental growth. Cognitive advances and increased pressures in late childhood and early adolescence result in repeated social anxiety. Adolescents have identified their most common anxieties as focused on relationships with peers to whom they are attracted, peer rejection, public speaking, blushing, self-consciousness, panic, and past behavior. Most adolescents progress through their fears and meet the developmental demands placed on them. More and more children are being diagnosed with social anxiety, and this can lead to problems with education if not closely monitored. Part of social anxiety is fear of being criticized by others, and in children, social anxiety causes extreme distress over everyday activities such as playing with other kids, reading in class, or speaking to adults.

In vivo neurochemistry of the ventral striatum and social competition in Homo sapiens

Alina Veronika Irene Strasser

Ventral striatal function and trait anxiety have been shown to influence reward-seeking behaviour and social competition in humans. Moreover, social status perceptions have been shown to modulate ventral striatal function. The neurochemical underpinnings of these associations have not been investigated in humans so far. Studies in rodents have previously shown that ventral striatal neurochemistry is associated with these concepts. In humans, objective and perceived social hierarchy position show some links to physical and mental health. Trait anxiety is understood as a predisposing factor underlying neuropsychiatric disorders and is associated with social anxiety. Fear and avoidance of social interactions, both inherent to environmental contexts of direct social competition, are hallmarks of social anxiety. Lost economic productivity due to anxiety and social status associated decrements in physical and mental health renders this scientific topic of high relevance to public health policies. Moving towards a deeper understanding of these associations might constitute an important part in ensuring public health. We combine proton magnetic resonance spectroscopy with personality profiling and an incentivised handgrip motivation task in a socially competitive context to investigate the neurochemical underpinnings of these associations in young adult men. We chose the occipital lobe as a control region. In addition, we have measured the salivary biomarkers cortisol, testosterone and alpha-amylase. We found that trait anxiety is negatively linked to taurine and positively to the excitation-inhibition balance. State anxiety was positively linked to lactate. The salivary biomarker alpha-amylase was found to be associated with both state anxiety and lactate. Social anxiety was positively linked to the excitation-inhibition balance. We also show links between reward-seeking task performance and ventral striatal glutamine, phosphorylethanolamine, GABA, choline, glutathione, myo-inositol, the excitation-inhibition balance and the ratio of glutamine to glutamate. These associations were observed in the ventral striatum but not the occipital lobe. Our methodological approach allowed us to gain a deeper understanding of the neuroscience underlying the links between ventral striatal function, anxiety and motivated behaviour. Thereby, we have extended the literature on the links between personality traits, social status and motivated behaviour in socially competitive contexts and the underlying neurobiology. These new findings pave the way for future experimental investigations to further elucidate the links between neurochemistry, mental health and socially competitive behaviour. A deep understanding of the neuroscience underlying personality traits and performance allow for effective interventions with the goal to ensure public health.

Sensory processing sensitivity

Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social and emotional stimuli". The trait is characterized by "a tendency to 'pause to check' in novel situations, greater sensitivity to subtle stimuli, and the engagement of deeper cognitive processing strategies for employing coping actions, all of which is driven by heightened emotional reactivity, both positive and negative".

Social anxiety disorder

Social anxiety disorder (SAD), also known as social phobia, is an anxiety disorder characterized by sentiments of fear and anxiety in social situations, causing considerable distress and impairing ability to function in at least some aspects of daily life. These fears can be triggered by perceived or actual scrutiny from others. Individuals with social anxiety disorder fear negative evaluations from other people. Physical symptoms often include excessive blushing, excessive sweating, trembling, palpitations, and nausea.

Glossophobia

Glossophobia or speech anxiety is the fear of public speaking. The word glossophobia derives from the Greek γλῶσσα glossa (tongue) and φόβος phobos (fear or dread.) The causes of glossophobia are uncertain but explanations include communibiology and the illusion of transparency. Further explanations range from nervousness produced by a lack of preparation to, one of the most common psychiatric disorders, Social anxiety disorder (SAD). Its symptoms include one or more of physiological changes, mental disruptions, and detrimental speech performance.
