Sex differences in emotional intelligence

The Mayer-Salovey-Caruso Emotional Intelligence Test is used to get emotional intelligence IQs (EIQ). The area scores include experiential EIQ and strategic EIQ. Experiential EIQ includes being able to recognize emotions to compare them to other sensations and their connection to the thought process. Strategic EIQ focuses on the meaning behind emotions, how emotions affect relationships, and how to manage emotions. After area scores, branch scores include four different sections: perceiving emotions, using emotions, understanding emotions, and managing emotions.[18] Using these categories, the test analyzes people's ability to perform tasks and solve emotional problems/situations. No self-perceived assessments are used in the test.[18]

Hiearchy of Mayer-Salovey-Caruso emotional intelligence test

A 246 university sample study published in the 2004 journal Personality and Individual Differences found women scored significantly higher than men on all scales of the MSCEIT.[19] Another 330 sample study published in the same year and same journal also found women scored significantly higher in emotional intelligence ability than men.[20] A 2006 sample study of 946 participants involving the University of Málaga and Yale University as well as researcher Peter Salovey found significantly higher scores obtained by women on overall scale and branches.[21] A 2010 meta-analysis published in the Journal of Applied Psychology by researchers Dana L. Joseph and Daniel A. Newman found that women scored higher than men by around half a deviation which amounts to 6–7 points difference.[9] A 2013 study published in the Journal of Personality Assessment by researchers Antonietta Curci and Tiziana Lanciano found that results are in line with those of previous studies showing that women consistently expressed higher emotional intelligence abilities than men (Brackett et al., 2004; Extremera et al., 2006; Salguero et al., 2012).[22] A 2014 study published in the journal PLoS ONE by researchers Jerzy Wojciechowski, and Maciej Stolarski found differences favoring women for performance-based EI ability tests supporting the held common hypothesis that women have higher EI scores than men do.[23] A 2016 study by researcher Tiziana Quarto published in the journal PLoS ONE found women had higher EI abilities among a group of 63 participants.[24]

This test is based on a theory provided by Peter Salovey and John Mayer,[25] which states that emotional intelligence has distinct, yet connected, categories. There are four categories.

1. The first one is called perception of emotions. It consists of being able to perceive, identify, and recognize emotions correctly.
2. Using emotions to facilitate thinking is the second category which means understanding emotions to then think and problem solve.
3. The third category, understanding emotions, includes understanding of emotional triggers and phases of emotional processing.
4. The last of the four categories is managing emotions. This category includes being able to regulate emotions and being able to handle other's as well.[25]

The TIE uses these categories in its structure.

The TIE focuses on measuring people's abilities, being an ecologically valid test, and the scoring being based on judgements by experts (instead of the population statistics). Multiple abilities are tested in theSr TIE, much more than compared to other emotional intelligence tests. These included fluid intelligence, verbal intelligence, personality, perception of emotion, and self-reported emotional intelligence. It can be looked at as valid alternative to the MSCEIT.[26]

A 2014 study plus meta-analysis published in the journal PLoS ONE with a sample size of 8979 participants found higher overall score by females on all facets of ability emotional intelligence. The analysis was conducted by researchers Magdalena Śmieja, Jarosław Orzechowski and Maciej S. Stolarski in various universities across Poland.[3] They also found in another study that although genders were equally adept at detecting consistency with basic emotions, women were superior at detecting deception in both basic emotion and inconsistent emotions conditions or in other words complex and subtle emotions.[23] The deviation size differences were 0.32 and the researchers attributed this to women's greater emotional intelligence.[23]

One example of using a behavioral study was a 2011 study published in the journal Sex Roles by researchers Matthew J. Hertenstein and Dacher Keltner. The study found that within a behavioral experiment study of 212 participants, women shared more emotions, felt more prosocial emotions and communicated much more happiness levels in one on one dyadic interaction.[13] Results also found that 79% of female decoders accurately identified male emotions and 96% accurately identified female emotions (both ps < .01). For male decoders, 70% (p = .052) correctly identified male encoders and 81% (p < .01) correctly identified female encoded emotions. Results conformed with findings from past literature.[13]

Social cognition is what allows people and animals to interpret tone, language, facial expressions, and body language.[27] Everyday, people use social cognition subconsciously as it is part of most modern society. Social cognition is an important part of emotional Intelligence and incorporates social skills such as processing facial expressions, body language and other social stimulus.[28]

A 2012 review published in the journal Neuropsychologia found that women are better at recognizing facial effects, expression processing and emotions in general.[14] Men were only better at recognizing specific behaviour which includes anger, aggression and threatening cues.[14] A 2012 study published in the journal Neuropsychology with a sample of 3500 individuals from ages 8–21, found that females outperformed males on face memory and all social cognition tests.[29] Another 2014 study published in the journal Cerebral Cortex found that females had larger activity in the right temporal cortex, an essential core of the social brain connected to perception and understanding the social behaviour of others such as intentions, emotions, and expectations.[30]

In 2014, a meta-analysis of 215 study sample by researcher A.E. Johnson and D Voyeur in the journal Cognition and Emotion found overall female advantage in emotional recognition.[10] Other studies have also indicated greater female superiority to discriminate vocal and facial expression regardless of valence, and also being able to accurately process emotional speech.[31] Studies have also found males to be slower in making social judgements than females.[32] Structural studies with MRI neuroimaging has also shown that women have bigger regional grey matter volumes in a number of regions related to social information processing including the inferior frontal cortex and bigger cortical folding in the Inferior frontal cortex and parietal cortex.[32] Researchers supposed that these sex differences in social cognition predisposes to high rates of autism spectrum disorders among males which is characterized by lower social cognition.[32] Two 2015 reviews published in the journal Emotion review also found that adult women are more emotionally expressive,[33][34] but that the size of this gender difference varies with the social and emotional context. Researchers distinguish three factors that predict the size of gender differences in emotional expressiveness: gender-specific norms, social role and situational constraints, and emotional intensity.[34]

Empathy is the ability to read emotional cues from others and to create an emotional connection during different social situations.[35] Empathy allows the user to organize their emotions in a way that allows them to broadcast what they feel, by what they say.[35]

A 2006 meta-analysis by researcher Rena A Kirkland in the North American Journal of Psychology found significant sex differences favoring females in "Reading of the mind" test. "Reading of the mind" test is an advanced ability measure of cognitive empathy in which Kirkland's analysis involved 259 studies across 10 countries.[36] Another 2014 meta-analysis in Cognition and Emotion, found overall female advantage in non-verbal emotional recognition across 215 samples.[10]

In a study published in 2006, neuroscientist Tania Singer showed that empathy-related neural responses are significantly lower in males when observing an "unfair" person experiencing pain.[37] Another 2014 study by researchers Chiyoko Kobayashi Frank, Simon Baron-Cohen and Barbara L. Ganzel found that on average women use networks in the brain associated with both cognitive empathy ( higher activity in mPFC) and emotional empathy (non-activity in the vmPFC) more than men, in which they inferred can somewhat explain why women have better performance in theory of mind or cognitive empathy skills.[12]

A 2014 analysis from the journal Neuroscience & Biobehavioral Reviews also found that there are sex differences in empathy from birth,[11] growing larger with age and which remains consistent and stable across lifespan. Females, on average, were found to have higher empathy than males at all ages, and children with higher empathy regardless of gender continue to possess high empathy throughout development in life. Further analysis of brain tools such as event related potentials found that females who viewed human suffering had higher ERP waveforms than males, an indication of greater empathetic response. Another investigation with similar brain tools such as N400 amplitudes found higher N400 in females in response to social situations which then positively correlated with self-reported empathy. Structural fMRI studies have also found females to have larger grey matter volumes in posterior inferior frontal and anterior inferior parietal cortex areas which have been correlated with mirror neurons indicated by the fMRI literature. Mirror neurons are crucial for many if not most aspects of empathy. Females were also found to have a stronger link between emotional and cognitive empathy. The researchers use The Primary Caretaker Hypothesis to explain the stability of these sex differences in development. According to the hypothesis, prehistoric males did not have the same selective pressure as women and this led to sex differences in emotion recognition and empathy.[11]

Another research, from PLOS One, found that sex differences in empathy vary dramatically depending on the method of assessment. While experimental and neuropsychological measures show no consistent sex effect, self-report data steadily indicates greater empathy in women. In a large-scale study (n = 10,802) the researchers measured empathy with an experimental empathy-for-pain task (EPT). Results showed some sex differences, but with minuscule effect sizes. In the second study, a subsample (n = 334) completed a self-report empathy questionnaire. Contrastingly to the first study, significant sex differences were found in self-reported empathy. Authors argue that self-reports may induce biases leading individuals to assume gender-role stereotypes.[7] The research from Developmental Cognitive Neuroscience compared age-related sex differences in both self-report and neurophysiological measures of empathic arousal in sixty-five 4–17-year-old children. Self-report indicated greater responsivity by females, which increased with age, while implicit hemodynamic and physiological measures did not demonstrate any gender-related patterns.[8]
