Emotion's Role In Cognitive Function: Understanding The Intricate Link

The relationship between emotion and cognition is a complex one. While cognition is an acquired process that develops through past experiences, thoughts, and senses, emotions are believed to be innate and present since birth. Both emotions and cognition are influenced by extensive interconnections between different regions of the brain. Emotions can impact our decisions and past experiences can affect our emotional health. Research has explored the idea of emotions providing information about one's internal state to the executive system, influencing cognitive functions. On the other hand, cognitive processes can also regulate emotions through strategies like cognitive reappraisal, which involves rethinking the meaning of emotionally charged events to alter their emotional impact. Understanding the interplay between emotion and cognition is crucial for fields like cognitive neuroscience and the development of neurocognitive models of psychopathology.

Emotional influences on decision-making

Emotions are often considered irrational occurrences that may distort reasoning. However, there are theories and research for both rational decision-making and emotional decision-making focusing on the important role of emotions in decision-making and the mental process and logic on the important role in rational decision-making.

Loewenstein and Lerner divide emotions during decision-making into two types: those anticipating future emotions and those immediately experienced while deliberating and deciding. Damasio formulated the somatic marker hypothesis (SMH), that proposes a mechanism by which emotional processes can guide (or bias) behavior, particularly decision-making.

Emotions can be divided into positive and negative emotions. Positive emotions can be further categorised into emotions of happiness and pleasure, while negative emotions can be further categorised into emotions of anger, fear, and sadness.

Anger is an activating emotion that makes people more likely to take risks and minimises how dangerous those risks will be. Angry people are more likely to rely on stereotypes and are more eager to act. Anger simplifies our thinking and makes us switch to rules of thumb instead of carefully considering policy and its implications.

Happiness is not much better at inspiring good decisions. Several studies have shown that people who were in a positive mood put more faith in the length of a message, rather than its quality, or in the attractiveness or likability of the source.

Under certain circumstances, sadness can be good, since it fosters systematic thought. The slightly melancholy, to whom no option appeals very much, will dutifully think, “on the one hand, x, but on the other hand y”. And that’s good! But too much sadness can set off rumination, which is not going to get you any closer to signing on the dotted line (or not!) with satisfaction and relief.

What’s more, sadness might make you more impatient. A 2013 study by Lerner and others found that people who felt sad accepted up to 34% less money in order to get paid now, rather than three months from now. But at least it might make you more generous toward others: She’s also found that sad people allocate more to welfare recipients than angry people would, since the angry would likely blame poor people for their own misfortune.

There appears to be no mood that would put you in the perfect frame of mind for, well, making up your mind. So what’s a decision-maker to do? The best bet might be to accept that you’re going to have emotions, but to try to keep them from influencing your thought process.

First, you could make yourself wait to react—though this can be hard when you have the perfect email retort burning through your drafts folder. You could also try to reappraise the situation, for example by viewing a layoff as a chance to finally pursue a lifelong goal, rather than as a crushing defeat.

Or, you could try to make your emotions irrelevant to your decision. Lerner recommends making a rubric with every element of a decision that’s important to you. For example, those deciding between two houses might list the number of bedrooms, the price, and the quality of the local schools. Next, assign each factor a weight—.2 or .5 and so on—so that all of the factors add up to one. Then score each option based on each dimension, and multiply the weights by the scores. You should end up a score that reflects the total, impartial assessment of each house’s relative merit.

Emotions are an integral part of the cognitive function and play a critical role in decision-making. While emotions can often be seen as irrational occurrences that may distort reasoning, they can also be a source of valuable information that can guide our decision-making.

The impact of emotional context on beliefs and action valuation

Emotions have a significant influence on cognitive control, and research has explored the idea of emotions providing information about one's internal state to the executive system. This suggests that emotions are a crucial part of the information that, along with external stimuli, is integrated to perform controlled actions.

The relationship between emotions and cognitive functions is complex and context-dependent. Emotions can influence cognitive functions in both facilitative and antagonistic ways. For example, emotional states can profoundly impact critical executive faculties such as inhibitory control, with impairments in this area linked to clinical disorders involving pervasive emotional states and difficulty regulating emotions.

The role of emotions in inhibitory control can be understood through well-established computational aspects of cognition, including beliefs, action valuation, and choice. Emotions can affect inhibitory behaviour by biasing prior expectations and associated changes in internal beliefs about various task-relevant events. For instance, the valence dimension of emotional states (appetitive/aversive) may primarily influence action parameters associated with approach and inhibition, exerting valence-congruent influences on outcome valuation and expectancies.

Furthermore, emotions can be considered additional context available to a decision-maker, which can then inform hypotheses about how such an emotional context may impact behaviour within a decision-making framework. This perspective allows for a direct relationship between emotion and other aspects of cognition, such as beliefs, valuation, and choice.

Recent research has identified areas in the ventral striatum and VTA that specifically encode instrumentally learned values of 'go' and 'no-go' actions, providing potential neural markers for tracking action valuation biases. Additionally, the OFC, involved in reward valuation and integrating motivational attributes of stimuli into decision-making, is likely to play a role in integrating emotional context into valuation biases.

In conclusion, emotions have a significant impact on beliefs and action valuation, influencing inhibitory control and other cognitive functions. By understanding the role of emotions in these processes, we can gain insights into the complex interplay between emotions and cognition.

Cognitive reappraisal as a strategy to regulate emotion

Cognitive reappraisal is a strategy used in cognitive behavioural therapy to regulate emotions. It involves recognising negative thought patterns and changing them into more effective ones. This can be done by altering how you perceive situations, which can help to dial down negative emotions, making it easier to address triggers with skill and maintain emotional balance.

Cognitive reappraisal can have a positive impact on emotional experience, problem-solving, physical health and relationships. It can also be used to improve one's ability to recover from a setback.

The role of the amygdala and insula in emotional responding

The amygdala and the insula are two key brain structures that play a crucial role in emotional responding. Located deep within the brain's temporal lobes, the amygdala is responsible for processing emotions, particularly fear. It connects our emotions to other brain functions, such as memory, learning, and our senses. Research has shown that the amygdala is particularly active during experiences of fear and contributes to a range of emotional responses, including those related to parenting and caregiving. The amygdala also plays a role in social communication and understanding, including interpreting others' intentions from their actions and speech.

The insula, on the other hand, is a folded region of the brain located deep within the cerebral cortex. It is involved in a variety of functions, including emotional responding and conscious perception of emotions. Studies have found that the anterior insula and amygdala play a crucial role in perceiving emotions conveyed through human voices. The insula is also associated with emotional arousal, a complex state that recruits distributed cortical and subcortical structures.

The amygdala and the insula have reciprocal connections and interact closely during emotional experiences. Arousal has been found to modulate the reciprocal connections between these two structures. Emotional arousal states, such as moderate levels of arousal, can facilitate executive function and prefrontal cortical activity, while high arousal states may impair these functions.

The amygdala and the insula, therefore, work together to process and respond to emotional stimuli. They are integral to our ability to perceive, understand, and respond to emotions, whether they are our own or those of others. Their functions are closely intertwined, and their interactions contribute to our overall emotional and cognitive experience.

How inhibitory control is linked to emotional states

Inhibitory control is the ability to inhibit one's prepotent response. It is an aspect of cognition that varies between individuals of the same species. It can be measured using a detour task, which explores whether an individual can inhibit the prepotent response of trying to obtain a reward directly through a transparent barrier and instead obtain it by detouring around the barrier.

Affective states can be perceived as negative or positive. Negative affective states can be measured using a tonic immobility test, which is the time taken by an individual to return to standing after being restrained on their back. Positive affective states can be measured using a cognitive judgement bias test, which is the latency to approach an ambiguous cue between a learnt rewarded and a learnt unrewarded cue.

In younger chicks, individuals with higher inhibitory control had a higher negative affective state and a lower positive affective state. This suggests that inhibitory control is positively linked to negative affective state and negatively linked to positive affective state. However, in older chicks and adults, there was no relationship between inhibitory control and affective states.
