Explain whether or not individual differences play a role in an individual’s behaviour

Assignment Brief

Requirements for Assignment 7 (500 words, APA)

Emotional intelligence (EI) is a component of “social intelligence” that refers primarily to a person’s understanding of their emotions and those of others. This week, you explore the EI concept, which includes self-awareness, mood management, motivation, empathy, and social skills, as well as exploring what we call the narrow personality variables of schizotypy. You may be familiar with the symptoms of schizophrenia, but you might be surprised to learn that the milder versions of those symptoms affect a vast number of “normal” people who continue to function normally in day-to-day life.

What we expect from your Assignment:

1. Analyse how/why tests of emotional intelligence correlate, or do not correlate, with an individual’s performance at school or work.
2. Evaluate whether or not this correlation equates to causation and explain your reasoning.
3. From your position on this debate, explain whether or not individual differences play a role in an individual’s behaviour.
4. Fully state and justify any choices or assumptions that you make using the suggested resources for this unit as well as your own research. Include references to any sources you have used. All sources should be cited using APA style.

Emotional Intelligence, Performance, and Individual Differences

Introduction

Emotional intelligence (EI) refers to the ability to recognise, understand, and manage one’s own emotions, as well as the emotions of others (Goleman, 1995). It encompasses key components such as self-awareness, mood regulation, motivation, empathy, and social skills. Given its social nature, researchers have investigated whether EI correlates with performance outcomes in academic and workplace settings. This essay analyses the relationship between EI and performance, discusses whether correlation implies causation, and evaluates the role of individual differences in shaping behaviour.

EI and Performance: Correlation or Not?

Several studies have found positive correlations between EI and academic or workplace performance. For example, Joseph and Newman’s (2010) meta-analysis reported that EI, particularly when measured using ability-based tests (e.g., Mayer-Salovey-Caruso Emotional Intelligence Test, MSCEIT), is moderately correlated with job performance, especially in roles requiring social interaction. Similarly, higher EI scores are linked to better classroom behaviour, peer relationships, and academic motivation (Petrides et al., 2004).

However, these correlations are often moderate and vary by context. For example, EI may predict success in emotionally demanding jobs (e.g., customer service, healthcare), but not in technical roles where emotional skills are less critical. Some studies argue that cognitive intelligence (IQ) and personality traits (e.g., conscientiousness) are better predictors of academic outcomes than EI alone (O’Boyle et al., 2011).

Does Correlation Equal Causation?

Although a correlation exists between EI and performance, it does not necessarily imply causation. Correlation merely indicates a relationship between two variables, not that one causes the other. For instance, high EI may be associated with better performance, but it could also be that people who perform well tend to develop emotional skills through experience or that a third factor (e.g., social support, personality) influences both EI and performance.

Moreover, longitudinal studies are needed to establish causation. While some experimental interventions show that EI training improves performance (Nelis et al., 2009), these findings must be interpreted cautiously due to variation in EI definitions and measurements. Therefore, we cannot confidently conclude that EI causes better performance; rather, it may be one of many contributing factors.

Role of Individual Differences

Individual differences, such as personality traits and narrow variables like schizotypy, significantly influence behaviour and may affect both EI and performance. For example, introversion may limit social skill development, while high empathy may enhance interpersonal effectiveness. Schizotypy, which includes milder forms of psychotic-like symptoms (e.g., odd beliefs, unusual perceptual experiences), may affect emotional processing but does not necessarily impair daily functioning (Claridge & Beech, 1995).

Therefore, individual differences moderate the impact of EI on behaviour. Not everyone with high EI will perform equally well, and other factors such as motivation, resilience, and contextual support must be considered. This suggests a complex interplay between traits, abilities, and environmental factors.
