The current meta‐analysis was designed to determine the relationship between executive function (EF) and empathy, as well as to identify any moderators. A search of Chinese and English databases yielded 18 studies and 67 effect sizes involving a total of 6006 participants. Results with the random effects model showed that EF was significantly positively correlated with empathy (r = .14, p < .001). Subgroup analysis showed that EF was more strongly related to cognitive empathy (r = .20, p < .001) than to affective empathy (r = .09, p = .03). Looking at the two dimensions of empathy, we further found that cognitive empathy is closely related to subcomponents of EF, including inhibitory control (r = .23, p < .001), working memory (r = .20, p < .001), and cognitive flexibility (r = .15, p = .036), while only affective empathy was closely related to inhibitory control (r = .12, p < .001). Results suggested that future research should consider that the relationship between empathy and EF varies depending on the division of specific subcomponents. This finding may help in explaining possible mechanisms of how EF affects empathy.

Regardless of a large amount of literature, whether empathy closely relates to depression is far from conclusive. The present study collected previous evidence and performed a meta-analysis to investigate the correlation between empathy and depression. By searching databases, 21 studies and 48 effect sizes were collected. Results showed that empathy was not correlated to depression (r = .006, p = .87). However, subgroup analyses showed that while the relationship between affective empathy and depression was significantly positively correlated (r = .108, p < .01), cognitive empathy was not (r = À.03, p = .26). Additionally, the relationship between empathy and depression varied during development, with a positive correlation in adolescence (r = .084, p < .01) and negative correlation in older adults (r = À.191, p < .001). Results implied that affective empathy might be one of the risk factors for depression, and higher affective empathy might mean more vulnerability to depression.Further studies would help by examining when and how this relationship builds, as well as the contributing factors of its development.

The function of empathic concern to process pain is a product of evolutionary adaptation. Focusing on 5- to 6-year old children, the current study employed eye-tracking in an odd-one-out task (searching for the emotional facial expression among neutral expressions, N = 47) and a pain evaluation task (evaluating the pain intensity of a facial expression, N = 42) to investigate the relationship between children’s empathy and their behavioral and perceptual response to facial pain expression. We found children detected painful expression faster than others (angry, sad, and happy), children high in empathy performed better on searching facial expression of pain, and gave higher evaluation of pain intensity; and rating for pain in painful expressions was best predicted by a self-reported empathy score. As for eye-tracking in pain detection, children fixated on pain more quickly, less frequently and for shorter times. Of facial clues, children fixated on eyes and mouth more quickly, more frequently and for longer times. These results implied that painful facial expression was different from others in a cognitive sense, and children’s empathy might facilitate their search and make them perceive the intensity of observed pain on the higher side.

Empathy for pain is evolutionally important and context-dependent. The current study explored the effect of physical cue on 4- to 5-year-old children’s empathy for pain with two experiments. Experiment 1 investigated the effect of valid and invalid physical cue as compared to baseline (without cue) in pain evaluation task (evaluating the pain intensity of a facial expression, N = 28). Experiment 2 employed eye-tracking to investigate the attentional process in valid and baseline conditions (evaluating the pain intensity of a body image with an apparently injured arm or leg, N = 65). We found the evaluation of pain intensity was the highest in the valid condition, and higher in baseline condition than invalid. As for eye-tracking results, children fixated more quickly, had more fixations and longer total fixation duration in valid-cue condition. Of attention allocation, compared with baseline condition, children fixated on arm/leg more quickly, more frequently and for longer time in valid condition. Additionally, eye-tracking results were significantly related to their evaluation of pain intensity.
