Excess Anxiety Impacts Attention to External Environment
A new study at the University of Granada has opined that being of a nervous disposition and being anxious at a given moment negatively impacts our attention to what happens around us even further.

The finding will help improve the treatment of anxiety disorders, so common in our days.

In fact, anxiety has become one of the most common conditions among the population, which can explain the negative connotations usually associated to this term.

Developed by Antonia Pilar Pacheco-Unguetti and colleagues, the study stated that there are two types of anxiety- trait anxiety, which is a quality of personality that indicates a tendency to feel anxiety and restlessness; and state anxiety, which is an emotional reaction raised in response to a stressful situation or context.

Thus, the later it is of a more immediate and ephemeral nature.

However, the difference between trait and state anxiety has not been identified or established for decades, on the grounds that both types of anxiety make individuals more receptive to negative information, to the detriment of positive or neutral information.

The researchers have evaluated whether these subtypes of anxiety affect attention differently.

For the study, an attention test prepared by the researchers was provided to some participants with high and low trait anxiety values, and to other groups of students that had been previously induced to a high state of anxiety or to a positive emotional state.

The results revealed double dissociation in attentional performance.

Cognitive control networks of participants with high trait anxiety values showed a deficient attentional performance.

Cognitive control networks are responsible for conflict resolution and voluntary action control, functions which are related to the prefrontal cortex.

On the other hand, the participants with high state anxiety presented an overfunctioning of the alerting and orienting networks, which are attention networks more heavily influenced by the process of analysis of stimuli.

The results obtained provide first evidence that trait and state anxiety affect attention processes differently.

In addition, the results also indicate that such influence is present in situations where emotional information processing is not required.

This dissociation may help develop specific therapies allowing patients with anxiety disorders to control themselves.

The aim is to help patients reinforce efficient mechanisms to focus on the demands of the situation by inhibiting distracting information.

The study will be published in the next issue of the prestigious journal Psychological Science.
