A large-scale study involving more than 15,000 volunteers has investigated the psychological factors behind why certain hugs are remembered long after the moment has passed. While many hugs are mundane daily greetings or farewells, a subset of embraces holds significant emotional weight. Events such as hugging a partner for the first time or sharing a final embrace with a dying parent are often cited as memories retained for a lifetime. Despite their importance, the specific psychological variables that distinguish these memorable hugs from ordinary ones remained unclear to researchers until recently. [1]
The research, titled “Why we hug: Individual differences predict emotional touch memories” and published in the scientific journal PLoS ONE, was led by Anna Lena Dueren of the University of Bristol in the UK. The team analyzed data from a massive survey distributed through BBC public broadcasting programs and other media outlets, recruiting a diverse group of 15,000-plus participants. Participants, ranging in age from 18 to 92, completed an online questionnaire detailing their habits and attitudes toward physical touch. They were asked to identify specific hugs they remembered for their positive emotional effects. Those who recalled such an instance were then required to select descriptive phrases from a predefined list explaining why the memory persisted. [1]
The survey also collected extensive data on personality traits and psychological factors. Variables assessed included attachment anxiety, avoidance, body acceptance, and body perception. Researchers examined whether participants’ childhood routines involved parental hugs, if they experienced difficulty hugging, or if they actively disliked the gesture. Empathy levels, hugging frequency, and the use of hugging as a standard greeting were also recorded. The results indicated a strong prevalence of positive tactile memory. Approximately two-thirds of the volunteers, totaling 10,457 individuals, reported remembering a specific hug due to its positive emotional impact on their well-being. [1]
When analyzing the reasons for these lasting memories, female volunteers most commonly cited comfort, understanding, and support as the primary factors. These elements underscored the nurturing and stabilizing role that physical embrace plays in female social bonding and emotional processing. Male volunteers displayed a remarkably similar pattern in their responses. The top reasons for remembering a hug positively were also comfort, understanding, and support, indicating that the fundamental emotional utility of hugging transcends gender distinctions. [1]
Advanced statistical modeling revealed that individual differences play a crucial role in how hugs are remembered. Individuals who disliked hugs, struggled with the mechanics of embracing, or exhibited avoidance in attachment were significantly less likely to recall a hug for its positive impact. Conversely, those who frequently used hugs as greetings, scored highly in empathy, or had high attachment anxiety and strong body perception scores were more likely to retain positive tactile memories. The study concludes that nearly seven in 10 people can pinpoint a specific hug because of the feelings it elicited. However, the likelihood of forming such a memory is contingent on a complex interplay of individual factors, including empathy levels, attachment styles, and body perception. These findings emphasize the profound emotional significance of hugging, suggesting that certain embraces become integral parts of an individual's autobiographical memory. The research builds on previous works, including S. Ocklenburg’s “The Psychology and Neuroscience of Hugging,” published by Springer in 2024, which established the multidisciplinary perspective on physical affection. [1]
