what is the mental impact of video games in younger generation

Research and theory indicate that repeated exposure to violent video games can increase the accessibility of aggressive thoughts and scripts, making hostile responses more likely in the short term. Cognitive priming models explain how imagined or enacted aggression in games activates associated ideas and action patterns; when those mental scripts are more readily available, a child or adolescent may interpret ambiguous situations more aggressively and respond accordingly (Anderson & Bushman, 2001). Experimental studies frequently report small-to-moderate increases in aggressive cognition, affect, and short-term behavior after playing violent games. Beyond immediate priming, repeated simulated violence can blunt emotional and physiological reactions to real-world harm. Laboratory work shows that participants who play violent games later display reduced heart-rate reactivity and lower self-reported empathy when exposed to violent images or scenarios, a pattern consistent with desensitization (Carnagey, Anderson & Bushman, 2007). Over time, this dampening of empathic arousal may lower inhibitory barriers against aggressive acts in some youths, especially those with other risk factors. These effects are neither uniform nor deterministic. Magnitude and persistence depend on dose (frequency and duration of play), the nature of game content (contextualized versus gratuitous violence; competitive framing), individual vulnerabilities (trait aggression, impulsivity), and social environment (parenting, peer norms). Most evidence points to transient effects rather than a simple causal chain from game play to severe real-world violence; nevertheless, the documented short-term increases in aggression-related cognition and the measurable reduction in empathic responding provide a plausible pathway by which heavy, chronic exposure could elevate risk for more aggressive behavior in susceptible young people (Anderson & Bushman, 2001; Carnagey et al., 2007; see also Ferguson, 2015 for qualification).
