this paper is a commentary to the article entitled :  are we overpathologizing everyday life ? a tenable blueprint for behavioral addiction research  , by billieux , schimmenti , khazaal , maurage and heeren ( 2015 ) .

backgroundthis paper is a commentary to the article entitled :  are we overpathologizing everyday life ? a tenable blueprint for behavioral addiction research  , by billieux , schimmenti , khazaal , maurage and heeren ( 2015).methods and aimsin this manuscript , we commented on two aspects developed by the authors . 
 billieux et al . 
 ( 2015 ) propose that the recent development of propositions of behavioral addiction is driven by an unwise application of an addiction model to excessive behaviors and rests on a confirmatory research strategy that does not question the psychological processes underlying the development of the conduct . 
 they also show that applying a process driven strategy leads to a more appropriate description of the reality of the behavior and conduct , in particular by describing a variety of motivations for the excessive behavior , which is central to understanding the nature of the conduct . 
 we believe that this new approach , which is fruitful to the emerging domain of behavioral addictions , could also apply to the domain of addictions in general . 
 the latter is characterized by the application of a generic biological model , largely influenced by animal models , focusing on neurophysiological determinants of addiction . 
 this approach may have decreased the attention paid to dimensions of addictions that are more specifically human . 
 we will firstly briefly argue on the limitation of this neurophysiological addiction model for the field of excessive behavioral conducts . 
 secondly , we will argue for an approach centered on the differentiation of motivations and on the adaptive dimension of the behavior when it first developed and on the evocation of a transition where the conduct became independent of its original function.conclusionsthe emerging domain of behavioral addictions , where no animal model has been developed so far , may bring a new reflection that may apply to the domain of addictions in general , 
 with a specific attention to human questions .
