“…Because of a very low rate of errors in cognitive test (range: 96%-99%) statistical analyses focused on RTs. Social challenges can induce extremely rapid biological effects in animals (e.g., neuropeptides release, Kelly & Wilson, 2019), with potential consequences on behaviour and cognition (see the discussion of Experiment 2 for additional information). We therefore conducted a preliminary analysis of the data and found that RT differences across conditions were mostly found on the very first trials following supplanting behaviour.…”

“…Since the goal of the current paper is mostly methodological, we will not discuss at length the behavioural and brain mechanisms by which the supplanting behaviours can affect RTs but will only briefly suggest three hypotheses that may account for our findings. A first potential mechanism is a release of steroid hormones which are known to occur in animals after social challenges (e.g., for a review see Kelly and Wilson, 2019). Androgens and especially testosterone are known to affect cognitive performance (e.g., Janowsky, 2006) and to enhance spatial abilities.…”

“…In preclinical research, direct administration of AVP into the hypothalamus of hamsters enhanced aggressive responding, while AVP antagonists attenuated aggression (Ferris et al 1997). OT has an important role in the modulation of social behaviors such as affiliation, parental bonding and care of young, social communication, and anxiety-like behaviors (Kelly and Wilson 2019). Preclinical research has demonstrated an antiaggressive role for OT that appears to be complex and strongly influenced by neurobiological systems that also modulate anxiety and stress (Kelly and Wilson 2019).…”

Cortisol and testosterone are steroid hormones that appear to influence aggression in an interdependent manner through the modulation of the amygdala's fear-or-threat neural circuits (Rosell and Siever 2015).…”

Objective: Aggressive behavior is among the most common reasons for referral to psychiatric clinics and confers significant burden on individuals. Aggression remains poorly defined; there is currently no consensus on the best ways to recognize, diagnose, and treat aggression in clinical settings. In this review, we synthesize the available literature on aggression in children and adolescents and propose the concept of impulsive aggression (IA) as an important construct associated with diverse and enduring psychopathology. Methods: Articles were identified and screened from online repositories, including PubMed, PsychInfo, the Cochrane Database, EMBase, and relevant book chapters, using combinations of search terms such as ''aggression,'' ''aggressive behavio(u)r,'' ''maladaptive aggression,'' ''juvenile,'' and ''developmental trajectory.'' These were evaluated for quality of research before being incorporated into the article. The final report references 142 sources, published from 1987 to 2019. Results: Aggression can be either adaptive or maladaptive in nature, and the latter may require psychosocial and biomedical interventions when it occurs in the context of central nervous system psychopathology. Aggression can be categorized into various subtypes, including reactive/proactive, overt/covert, relational, and IA. IA in psychiatric or neurological disorders is reviewed along with current treatments, and an algorithm for systematic evaluation of aggression in the clinical setting is proposed. Conclusions: IA is a treatable form of maladaptive aggression that is distinct from other aggression subtypes. It occurs across diverse psychiatric and neurological diagnoses and affects a substantial subpopulation. IA can serve as an important construct in clinical practice and has considerable potential to advance research.

“…subtypes 143 ; and describe how these behaviors are regulated, 144 are sexually dimorphic, 145 and depend on (social) context. 146 Brain-based models of outbursts can offer clues about their etiology and how certain behaviors might be reinforced, particularly in subpopulations. For example, expression and activation of orexin neurons in the lateral hypothalamus promote male-to-male aggression in mice.…”
