Spontaneous helping behavior of autistic and non-autistic (Pre-)adolescents: A matter of motivation?

ABSTRACT: Young autistic people have a range of social difficulties, but it is not yet clear how these difficulties can be explained. In addition, emerging research is suggesting that autistic girls may differ from boys in terms of their social behaviors, but yet unknown is if they differ in terms of their pro-social behavior, such as helping. The present study investigated spontaneous helping behavior using an in vivo paradigm and related this to participants' levels of social motivation (based on parent reports). Participants were 233 autistic and non-autistic (pre-)adolescents (M = 12.46?years, SD = 15.54?months). Our results demonstrated that autistic girls and boys have lower levels of social motivation compared to their non-autistic peers, but social motivation was unrelated to helping behavior in both groups. Furthermore, when the experimenter needed help, the autistic boys and girls looked and smiled to the same extent as their peers of the same gender, but they actually helped significantly less than their non-autistic peers. However, most autistic youngsters did help, highlighting the great individual differences in autistic individuals. We discuss the possibility that lower levels of helping behavior are due to difficulty initiating action in a social context, rather than lower social motivation.

LAY SUMMARY: This study examined the helping behavior of autistic boys and girls (aged 9-16). Many autistic young people did help, but compared to non-autistic individuals, autistic people did not help as much. This study also showed that when people did/did not help, it was not related to their interest in social relationships. It is important to teach young autistic people when and how to help others, to support them making friends.

Project description:Despite decades of research with humans, the biological mechanisms that motivate an individual to help others remain poorly understood. In order to investigate the roots of pro-sociality in mammals, we established the helping behavior test, a paradigm in which rats are faced with a conspecific trapped in a restrainer that can only be opened from the outside. Over the course of repeated test sessions, rats exposed to a trapped cagemate learn to open the door to the restrainer, thereby helping the trapped rat to escape (Ben-Ami Bartal et al., 2011). The discovery of this natural behavior provides a unique opportunity to probe the motivation of rodent helping behavior, leading to a deeper understanding of biological influences on human pro-sociality. To determine if an affective response motivates door-opening, rats receiving midazolam, a benzodiazepine anxiolytic, were tested in the helping behavior test. Midazolam-treated rats showed less helping behavior than saline-treated rats or rats receiving no injection. Yet, midazolam-treated rats opened a restrainer containing chocolate, highlighting the socially specific effects of the anxiolytic. To determine if midazolam interferes with helping through a sympatholytic effect, the peripherally restricted beta-adrenergic receptor antagonist nadolol was administered; nadolol did not interfere with helping. The corticosterone response of rats exposed to a trapped cagemate was measured and compared to the rats' subsequent helping behavior. Rats with the greatest corticosterone responses showed the least helping behavior and those with the smallest responses showed the most consistent helping at the shortest latency. These results are discussed in terms of their implications for the interaction between stress and pro-social behavior. Finally, we observed that door-opening appeared to be reinforcing. A novel analytical tool was designed to interrogate the pattern of door-opening for signs that a rat's behavior on one session influenced his behavior on the next session. Results suggest that helping a trapped rat has a greater motivational value than does chocolate. In sum, this series of experiments clearly demonstrates the fundamental role of affect in motivating pro-social behavior in rodents and the need for a helper to resonate with the affect of a victim.

Project description:Empathy is the ability to (a) be affected by and share the emotional state of another; (b) assess the reasons for the other's state; and (c) identify with the other, adopting their perspective. This phenomenon has been shown to exist in several species and is proposed as a motivator for prosocial behavior. The experimental study of this feature in laboratory rodents is a more viable alternative in comparison to wild animals. A recent report showed that rats opened a door to free their cage mate from a restraint box. Although this behavior has been suggested to be motivated by empathy, this fact has been questioned by several studies that proposed other motivators for the releasing behavior. In the present study, we use an adaptation of the protocol of releasing behavior to investigate aspects of empathy and pro-sociality such as familiarity and reciprocity. In addition, we addressed some potential motivational factors that could influence this behavior. The main results showed that (1) rats opened the restraint box to free conspecifics most of the time; (2) direct reciprocity or past restriction experience did not improve releasing performance, probably due to a ceiling effect; (3) after a series of trials in the presence of a restricted conspecific, the free rat continues to open the restraint box even if it is empty; (4) in general, the opening performance improves across trials and phases, resembling learning curves; (5) if the first series of trials occurs with the empty box, the opening behavior does not occur and is modest in subsequent trials with a trapped animal; (6) the exploratory drive toward the restraint box and desire for social contact do not seem to function as key motivators for releasing behavior. In conclusion, our findings do not support that the opening behavior is exclusively related to empathic motivation. While multiple factors might be involved, our study suggests that task learning triggered (and possibly reinforced) by the presence of the restricted rat can function as a motivator. Further investigations are required to fully understand the mechanisms and motivation factors guiding the releasing behavior.
