The Science of Phone Anxiety: Why Watching 'Last Seen' Doesn't Calm You Down

Brunel University London

Tara C. Marshall

Known for:Research linking attachment style to Facebook-related jealousy and partner surveillance

Key findings

  1. 2013

    Across two separate samples, higher attachment anxiety predicted more Facebook surveillance of a partner while higher attachment avoidance predicted less; the anxiety-surveillance link was explained in part by lower trust and greater day-to-day jealousy in a week-long diary study.

The Ohio State University

Jesse Fox

Known for:Research on relational uncertainty, attachment, and partner surveillance on social networking sites

Key findings

  1. 2014

    Relationship uncertainty, more than any confirmed partner behavior, predicted partner surveillance on Facebook; attachment anxiety was what drove that uncertainty upward in the first place, replicating and extending earlier attachment-and-surveillance findings.

University of Michigan (now Arizona State University)

Lauren A. Reed

Known for:Coining 'electronic intrusion' and tracing it to attachment anxiety across college and high-school dating relationships

Key findings

  1. 2015

    Among college students in dating relationships, reading a partner's private messages, tracking their whereabouts, and monitoring who they talk to — all without permission — was predicted by attachment anxiety in both men and women.

  2. 2016

    Extending the same construct to 703 high-school students, higher attachment anxiety again predicted more frequent electronic intrusion — reading messages, monitoring whereabouts, and pressuring a partner for constant contact — for both girls and boys.

Reichman University (Interdisciplinary Center Herzliya)

Mario Mikulincer

Known for:Co-developing (with Phillip Shaver) the regulatory model of adult attachment — mapping how anxious and avoidant hyperactivating and deactivating strategies produce specific cognitive distortions including negative intent attribution and catastrophizing

Key findings

  1. 2003

    With Phillip Shaver, Mikulincer demonstrated experimentally that priming secure-base representations — even subliminally — reduced hostile attributions and increased tolerance toward out-group members, showing that attachment-driven distortions are malleable states rather than fixed traits.

  2. 2007

    With Phillip Shaver, Mikulincer synthesized the adult attachment field in Attachment in Adulthood, cataloguing how the hyperactivating strategy of anxious attachment generates systematic cognitive distortions: hypervigilance to rejection cues, mind reading biased toward negative intent, catastrophizing minor disruptions, and 'people always leave' schemas maintained by confirmation bias.
