Discussion
The study aimed to investigate the relationship between empathy and prosocial behaviour in young children with ASD and typically developing children. It also looked at how other social factors might mediate or moderate the relationship between the study variables.
The study found that children with ASD were less empathetic than their TD peers, more specifically in terms of overall empathy and its two dimensions: attention to others’ feelings and prosocial empathy. No differences were found in emotional contagion. This is consistent with previous research findings based on parental reports (Li et al.,
2023). The results show that children with autism have difficulty paying attention to other people’s emotions and engaging in prosocial actions towards another person. When exposed to someone’s emotional expressions, autistic children may feel stressed because they have difficulty understanding the emotions being conveyed. To cope with this stress, individuals with ASD may shift their focus elsewhere (Markram & Markram,
2010; Li et al.,
2023).
Children with ASD were assessed by their parents as less prosocial than TD children, which is in line with the previous findings (Li et al.,
2023). Prosocial behaviour requires three social-cognitive abilities: recognising the negative experiences of others, knowing how to respond, and being motivated to act (Ryan-Enright et al.,
2022). Therefore, children with ASD may have more difficulty understanding and predicting the emotions or behaviours of others, and they may be less motivated to act prosocially. Moreover, prosocial behaviour have been defined as comforting, helping, and sharing behaviours. Children with autism may express their prosocial behaviour differently. Instead of comforting, they may show care and support by quietly and attentively listening to others (Crompton et al.,
2020).
Children with autism spectrum disorder engaged in social interactions significantly less frequently compared to their TD peers. On the other hand, children with ASD had significantly higher levels of externalising symptoms and attention difficulties compared to their TD peers. This is consistent with the findings of other researchers (Mingins et al.,
2021; Tsou et al.,
2021) suggesting that children with ASD stand an increased risk of challenging behaviours and decreased adaptive behaviours.
The present study has found that levels of internalising symptoms, i.e., levels of anxiety, did not differ between the two groups of children. These findings are contrary to other studies (Mingins et al.,
2021; van Steensel & Heeman,
2017), that examined older children with ASD. The reason for this may be that the study involved parents evaluating very young children (aged 1.5-4 years) experiencing separation anxiety, which caused both groups of parents to observe anxiety in their children. It is possible that these differences may increase with age (anxiety decreases in TD children, while it increases in children with ASD), as this was confirmed in the study of older children with ASD (Mingins et al.,
2021).
The results of this study confirmed gender differences only in the group of typically developing children: the girls had higher levels of prosocial empathy and behaviour, while the boys had a higher level of externalising symptoms. This is consistent with previous research showing that girls and women often outperform boys and men on standardised tests measuring empathy, social sensitivity and emotion recognition (Mingins et al.,
2021). No gender differences were observed in the group of children with ASD, which is in contrast to previous findings (Baron-Cohen,
2010; McChesney & Toseeb,
2018). The explanation is perhaps to be found in the age of the children studied and their attendance of a nursery or kindergarten, where all children undergo the same process of socialisation regardless of gender. Although many studies confirm that TD boys and boys with ASD face lower social pressures and expectations regarding empathic and prosocial behaviour compared to girls (Smith,
2009), these findings have shown that such gendered social expectations and stereotyped social roles are not yet transparent in young children, especially those attending a nursery or kindergarten (Lasota,
2023). Perhaps the presence of siblings (Ben-Itzchak et al.,
2016) and natural contact with other children in the family or at a nursery contributes to better functioning in young children with ASD, irrespective of their gender. This is consistent with the social learning theory, which posits that prosocial behaviour develops when (neurotypical) children learn social norms of reciprocity and social responsibility (Ryan-Enright et al.,
2022).
The results confirmed that empathy was directly related to prosocial behaviour in children with autism as well as in their neurotypical peers. However, only prosocial empathy was a significant predictor of prosocial behaviour. The other two dimensions of empathy, emotional contagion, and attention to others’ feelings, were not directly related to the level of prosocial behaviour observed by the parents. This finding should not be surprising, as prosocial empathy involves emotions that lead a person to engage in helping or comforting behaviours. Experiencing prosocial empathy requires understanding others’ emotions and social roles. As children begin to recognise the basic emotions, they simultaneously develop prosocial behavioural intentions (Tsou et al.,
2021).
The finding revealed that social interactions correlated with empathy and prosocial behaviour only in typically developing children. Attention to others’ feelings and prosocial empathy were positively associated, while emotional contagion was negatively associated with social relationships in TD children. Social interactions were a significant mediator that strengthened the relationship between empathy and prosocial behaviour in neurotypical children. However, in children with autism spectrum disorder, the relationship between empathy and prosociality was not mediated by positive social interactions. This result can be explained by the fact that impaired social attention ultimately deprives the child of relevant social learning experiences, causing an imbalance in the reception of social and non-social stimuli, and subsequently disrupting their social and cognitive development (Wang et al.,
2022).
These findings confirmed that early psychopathological symptoms mediate the relationship between empathy and prosociality in young children. In typically developing children, two out of three dimensions of empathy were found to be associated with psychopathological symptoms. Emotional contagion was positively and prosocial empathy negatively associated with all negative socialisation behaviours. This means that typically developing children who have difficulty regulating their own emotional arousal and understanding other people’s emotions are more likely to experience externalising symptoms. Moreover, externalising behaviour emerged as a significant mediator weakening the relationship between empathy and prosocial behaviour.
In children with autism spectrum disorders, a completely different relationship was found. Interestingly, and in contrast to previous findings in older children with ASD (Fitzpatrick et al.,
2016; Montiel-Nava & Peña,
2011), empathy was not correlated with externalising behaviour or attention difficulties in this study. Social interaction was a positive and attention difficulties a negative predictor of prosocial behaviour in children with ASD. The mediator of the relationship between empathy and prosocial behaviour was found to be internalising behaviour. The negative association between empathy and anxiety was in line with previous research (Sönmez,
2020), but in contrast to others (Gambin & Sharp,
2018). On the other hand, these findings show that children with ASD who felt anxious exhibited more prosocial behaviour.
Furthermore, anxiety was found to act not only as a mediator, but also as a moderator in the relationship between empathy and prosocial behaviour in children with ASD. This relationship between empathy and prosociality was the strongest at higher level of anxiety. Perhaps anxiety is a motivator for children with ASD to observe and imitate the behaviour of other children. Tibi-Elhanany and Shamay-Tsoory (
2011) have found that autistic individuals with high social anxiety showed greater sensitivity and attentiveness to other people’s states of mind. High levels of anxiety may make children with autism more attentive to others’ emotions. Children with ASD who have higher levels of anxiety may also have better mentalising and empathising skills, leading to more prosocial behaviour. The findings are also consistent with those of Rosen and Lerner (
2016), who confirmed that in adolescents with ASD, improvement in facial emotion recognition was enhanced by internalising symptoms but attenuated by externalising symptoms. The results of this study confirm that the relationship between empathy, prosocial behaviour and anxiety in children with ASD is not clear-cut and is much more complex.
Limitations
This study has some potential limitations that should be considered. First, it was a cross-sectional study based solely on parental reports. The results should be interpreted cautiously because empathy traits and prosocial behaviour in daily life were parent-reported, indicating the potential measurement error. Second, 14% of the children in the ASD group were under 30 months old and had not yet been clinically diagnosed. Third, the researchers did not have access to a full diagnosis of the children with autism spectrum disorders, which limited the inclusion of other variables in the analyses, such as intelligence or communication levels of the children with ASD and TD group. It is also likely that there were differences in general developmental and language skills between the groups, making it difficult to conclude how much of the findings are specific to autism and how much is due to broader developmental delays. Moreover, this study considered prosocial behaviour as a total variable. Including of three dimensions of prosocial behaviour may have revealed additional interesting relationships. Finally, a limitation of the study is that the sample consisted only of Polish parents and therefore the results cannot be generalised.
Despite these limitations, these findings represent one of few studies that have examined the relationship between empathy and prosocial behaviour while additionally considering social interactions and early psychopathological symptoms in children with ASD compared to their TD peers. This study found that in early childhood, the relationship between empathy and prosocial behaviour differs between children with ASD and neurotypical children, based on their behavioural and social-emotional functioning. This study may have practical implications for social skills training programmes based on behavioural interventions. The findings suggest that intervention programmes to develop emotional-social skills should target a specific group of children in early childhood. To strengthen the link between empathy and prosociality, the focus should be on reducing externalising behaviours in typically developing children, and on reducing internalising behaviours in children with ASD.
