Report: Haptic Test Series "Felix the Attacking Goalkeeper" in the Context of Children's 1-on-1 Soccer Games Under Atmospheric Stress

Experimental Setup & Setting:
As part of an exploratory haptic study, the behavior of a child subject named Felix in the role of an active goalkeeper was examined. The test environment consisted of an improvised soccer field with 1-on-1 rules, set up on the grounds of a temporary container shelter. The immediate environment was characterized by atmospheric remnants of an architecturally and symbolically charged past (presumably from the Nazi era, e.g., crumbling concrete fragments, faded military emblems, archaic loudspeaker remnants), whose smell and visual presence represented a non-trivial sensory influence on the participants.

Aim of the test:
Investigate tactile and proprioceptive stimulus processing under stress and memory induction, as well as the role of spontaneous childhood aggression in a sporting context. Particular attention was paid to:

• tactile self-perception during physical contact (e.g., catching the ball, impact with an opponent)

• sensory filtering performance under disruptive odor and environmental influences

• aggressive goal orientation as a haptic-somatic action unit

Observations:
Felix demonstrated highly impulsive defensive behavior with strong physical effort. Particularly striking was his willingness to break out of the typical goal-scoring position and offensively push into the opponent's path – This was assessed as a "haptically aggressive expansion of the goalkeeper zone."

Upon direct contact with the ball, Felix reacted with a fan-like hand spread and a strong buildup of pressure—typical signs of compensatory sensory overload strategies. The container walls reflected the voices of bystanders, leading to auditory and thus secondary haptic irritation (movement toward the sound source instead of toward the ball).

The aromatic backdrop—musty-metallic, mixed with children's sweat, plastic turf, and waste oil—created a paradoxical memory field that briefly prolonged Felix's reaction time when catching the ball. In interviews, he later described this as "a strange feeling on the nose—like being in grandpa's basement, but you still have to run."

Interpretation:
The aggressive goalkeeping tactic can be interpreted as a haptic-emotional gesture of demarcation—a "territorial echo" of the cramped and historically burdened container environment. Here, tactile defense becomes self-protection in a symbolic battlefield, with the child's nervous system oscillating between athletic play and diffuse historical unease.

Conclusion:
Felix serves as an example of the fusion of bodily memory, present-day stimuli, and spatial-cultural atmosphere. Here, haptics is not just a sensorium of touch, but an active modulator in the interplay between the past, the instinct to play, and identity construction.

Recommendation:
Further studies with multisensory support (e.g., thermal cameras, feedback vests, olfactory filters) are recommended to more precisely capture the dynamics of children's body perception in a semi-traumatic setting.
