Summary

Photography was once a rare and deliberate act. Today, the smartphone has transformed it into an almost automatic gesture: a reflex, a habit, a way of outsourcing memory to a device. We photograph everything, yet revisit almost nothing. Thousands of images accumulate silently within our phones, forming vast personal archives that remain only partially connected to conscious recollection.

This thesis examines a fundamental paradox at the heart of contemporary memory practices: while digital technologies enable the preservation of more moments than ever before, they may simultaneously weaken the depth and intentionality of personal recollection. In delegating the act of remembering to an external device, we risk eroding the very capacity we are trying to protect.

The central question driving this research is: in what ways do visual memory and digital storage influence our relationship to personal recollection?

The thesis draws on three bodies of inquiry. First, an extensive literature review spanning cognitive psychology, media studies, and digital memory research, bringing together scholarship on cognitive offloading, the photo-taking impairment effect, collective memory, and the algorithmic organization of personal archives.

Second, a field study conducted through semi-structured interviews with twelve participants across three generations, from teenagers to elderly individuals who witnessed the entire arc of photographic history. Their testimonies reveal a rich and contradictory landscape: fear of forgetting, the comfort of sensory triggers, the ambivalence of nostalgia, the emotional weight of physical prints, and the strange experience of losing years of memories when a phone dies.

Third, a design research dimension that opens onto future practice, identifying three key challenges for designers: how to reintroduce hierarchy and intentionality into digital memory; how to enrich digital records with sensory and emotional dimensions that pure images cannot capture; and how to design systems that balance external storage with the active exercise of human memory.

01

The Digital, an Infinite Memory Box

An exploration of digital storage as external memory, the history and cultural impact of photography, and the proliferation of platforms and mediums through which images are now produced and shared.

02

Field Research

Semi-structured interviews with twelve participants across three generations. Key findings: the universality of the fear of forgetting, the primacy of sensory triggers over photographic ones, the emotional superiority of physical albums, and the paradox of photographs that make us forget faster.

03

Digital Technology and Human Memory: a Profound and Ambivalent Impact

A critical analysis of digital amnesia, the Google Effect, collective memory in the digital age, and emerging practices that seek to reconnect individual fragments to shared cultural narratives, from The Anonymous Project to Beijing Silvermine.
