Short answer

When designing for users who report memory fragmentation, focus on supporting their cognitive processes of memory attribution and integration, rather than solely on enhancing recall mechanisms.

Field: User-Centred Design
Source: Data Archiving and Networked Services (DANS) (2003)
Method: Experimental study with a control group simulating DID.
Evidence: Moderate effect

Individuals with Dissociative Identity Disorder (DID) may perceive amnesia between identities due to a cognitive misattribution of retrieved memories, rather than an actual impairment in memory encoding or retrieval. This user-centred design research insight is drawn from a 2003 study published in Data Archiving and Networked Services (DANS). Using Experimental study with a control group simulating did., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for users who report memory fragmentation, focus on supporting their cognitive processes of memory attribution and integration, rather than solely on enhancing recall mechanisms.

Subjective Amnesia in Dissociative Identity Disorder Stems from Cognitive Appraisal, Not Memory Failure

Data Archiving and Networked Services (DANS) · 2003

Key Findings

01Patients with DID did not exhibit objective evidence of amnesia between identities; instead, information transfer between identities was observed.
02The subjective experience of amnesia in DID may arise from a faulty cognitive evaluation of memory recollection, where retrieved memories are misattributed to specific identities.

Application

Design takeaway

When designing for users who report memory fragmentation, focus on supporting their cognitive processes of memory attribution and integration, rather than solely on enhancing recall mechanisms.

How to apply

When designing digital journaling or personal information management systems for individuals with DID, incorporate features that allow users to tag, categorize, and reflect on memories, facilitating a more integrated understanding of their experiences.

Project actions

01When researching user experiences, differentiate between objective performance and subjective perception.
02Consider how cognitive biases or mental states might influence how users interact with a product.

Method & Evidence

AimTo investigate whether objective evidence for interidentity amnesia in Dissociative Identity Disorder (DID) exists under controlled experimental conditions, and to explore the discrepancy between subjective reports of amnesia and objective memory performance.

MethodExperimental study with a control group simulating DID.

ProcedureParticipants with DID and a control group instructed to simulate DID were tested on various encoding and retrieval tasks using neutral and trauma-related information. Memory performance was measured using tasks designed to be difficult to simulate amnesia symptoms on.

ContextPsychological research on dissociative disorders and memory functioning.

Variables

IVPresence of Dissociative Identity Disorder (DID) vs. simulated DID.

DVObjective memory performance on encoding and retrieval tasks; subjective reports of amnesia.

CVType of information (neutral vs. trauma-related), specific encoding and retrieval tasks used, instructions given to the control group.

Strengths & Limitations

Strengths

+Rigorous experimental conditions aimed at minimizing simulation effects.
+Inclusion of a control group instructed to simulate DID.

Limitations

The complexity of DID means that generalizing findings from a specific experimental setup to all individuals with DID is challenging. The control group's simulation might not perfectly replicate the lived experience.

Reliability & validity

Reliability would depend on the consistency of memory performance across repeated administrations of the same tasks. Validity is addressed by using tasks difficult to simulate and by comparing DID patients to a simulated control group, aiming to distinguish genuine effects from simulation.

Think critically

If the amnesia is a cognitive evaluation, what are the implications for designing assistive technologies that aim to 'restore' lost memories versus those that aim to help users contextualize and integrate existing memories?

Design Principles

"Design for cognitive appraisal: Acknowledge that user perception and interpretation of information are as critical as the information itself, especially in contexts of subjective experience."

This insight is crucial for designers developing tools or interfaces for individuals with DID. Understanding that the perceived memory gaps are cognitive evaluations rather than true memory loss can inform the design of supportive technologies that focus on aiding cognitive appraisal and integration of memories, rather than solely on memory recall.

What This Means for Your Design

People with DID often feel like they forget things when another 'part' of them is in charge. But this study found that their memories are actually there, they just misjudge which 'part' the memory belongs to. So, it's more about how they think about their memories than actually forgetting them.

How to use in your project

1.This research can inform the user research phase by suggesting that direct questioning about memory recall might be less fruitful than exploring how users interpret and categorize their experiences.

Paragraph starter

Research by Huntjens (2003) suggests that perceived amnesia in Dissociative Identity Disorder may stem from cognitive appraisal rather than memory impairment. This implies that design interventions should focus on supporting users' interpretation and integration of information, acknowledging that subjective experience can diverge from objective memory retrieval capabilities.
