Top1. Introduction
Cognitive performance (
) is a mental capacity that is affected by inhibitory control and executive functions, which are factors responsible for the planning, intellectual organization and behavior control (Diamond., 2013; Ruiz-Ariza et al., 2017). Memory, visual acuity, concentration and numeric-linguistic reasoning abilities appear among the most important components of 
(Ruiz et al., 2010; Diamond., 2013; Esteban-Cornejo et al., 2015; Ruiz-Ariza et al., 2017). It has been observed that young people with high 
have greater self-esteem and self-concept (Fati-Ashtiani et al., 2007), and they show less risk of chronic widespread pain (Gale et al., 2012). However, low 
has been associated with anxiety disorder (Martin et al., 2007), depression (Jaycox et al., 2009), and psychological distress (Gale et al., 2008). Therefore, to ensure a better living of mankind, it’s necessary to find an effective mean of 
improvement as well as rehabilitation.
Brain games (
) have been enormously being considered for a long time as one of the most cost-effective, entertaining and compelling means for the progressive improvement of 
(Lowery & Knirk., 1982; Dorval & Pepin., 1986; Drew & Waters., 1986; McClurg & Chaille., 1987; Dustman et al., 1992; Okagaki & Frensch., 1994; Subrahmanyam & Greenfield., 1994; Greenfield et al., 1996; Yuji., 1996). Recently, scholars also proposed several 
that mostly offer single-player gaming mode in this regard (Chuang & Chen, 2009; Byun & Park, 2011; Foukarakis et al., 2011; Vasconcelos et al., 2012; Belchior et al., 2013; Navarro et al., 2013; Cecilia et al., 2014; Lopez-Samaniego et al., 2014; Matsushima et al., 2014). However, in order to achieve their ultimate goal, a challenge is to keep players committed to undertake 
playing activity on regular bases for a longer period of time (Roschelle et al., 2000; Aison et al., 2002; Garris et al., 2002; Melenhorst., 2002; Eggermont at al., 2006; Ijsselsteijn et al., 2007; Pearce., 2008; O’Donovan., 2012). Single-player games, especially of serious nature such as 
, normally lack in this regard. To overcome this issue, Faizan et al., 2017 designed a cooperative yet competitive multiplayer gaming environment for the 
of “BrainStorm” game suite, which triggers the psychosocial factors of motivation among the players to achieve their long-term commitment with 
playing activity. However, the proposed solution didn’t delineate against the following contradictory facts about players’ 
that potentially induce due to the psychosocial factors during the multiplayer mode of 
play.
