Abstract

Although recent studies suggest that the mere presence of a smartphone might negatively impact on working memory capacity, fluid intelligence, and attentional processes, less is known about the individual differences that are liable to moderate this cognitive interference effect. This study tested whether individual differences in emotion-related impulsivity traits (positive urgency and negative urgency) moderate the effect of smartphone availability on cognitive performance. We designed an experiment in which 132 college students (age 18–25 years) completed a laboratory task that assessed visual working memory capacity in three different conditions: two conditions differing in terms of smartphone availability (smartphone turned off and visible, smartphone in silent mode and visible) and a condition in which the smartphone was not available and was replaced by a calculator (control condition). Participants also completed self-reports that assessed their thoughts after the task performance, positive/negative urgency, and problematic smartphone use. The results showed that participants with higher positive urgency presented increased cognitive interference (reflected by poorer task performance) in the “silent-mode smartphone” condition compared with participants in the “turned-off smartphone” condition. The present study provides new insights into the psychological factors that explain how smartphone availability is liable to interfere with high-level cognitive processes.

TL;DR

In a lab experiment with 120 college students, smartphone availability affected visual working memory capacity, and this cognitive interference was moderated by positive urgency but not negative urgency. Higher positive urgency was linked to poorer working memory in the silent-mode smartphone condition than in the turned-off smartphone condition, especially on the most difficult task set size.

Key findings

  • Positive urgency moderated the effect of smartphone condition on visual working memory: condition × positive urgency interaction χ²(2) = 7.22, p = 0.03, d = 0.51; the model including this interaction best fitted the data (AIC = 614.56, Akaike weight = 0.59).
  • Participants higher in positive urgency performed worse in the silent-mode smartphone condition than in the turned-off smartphone condition (χ²(1) = 6.42, p = 0.03, d = 0.49); overall, silent-mode vs. turned-off performance showed B = 0.78, 95% CI [0.15, 1.41], t = 2.05, p = 0.03, d = 0.38.
  • The positive urgency × condition effect was significant only at the most difficult set size (four squares: F(1,114) = 8.36, p = 0.01), not at set size 3 (p = 0.08) or set size 2 (p = 0.07).
  • Negative urgency did not interact with condition; problematic smartphone use was not significantly associated with task performance (χ²(1) = 0.68, p = 0.40), and no differences were found between calculator and turned-off conditions (p = 0.32) or calculator and silent-mode conditions (p = 0.22).

Methods

  • Experimental laboratory study: 132 college students aged 18–25 were recruited; final sample was 120 (65% female, Mage = 22.73, SD = 1.67) after exclusions. Participants were randomly assigned to turned-off smartphone (n = 40), silent-mode smartphone (n = 41), or calculator control (n = 39).
  • Visual working memory was assessed with a single-probe recognition task (240 trials; set sizes of two, three, or four coloured squares; Cowan’s K). Self-reports measured positive urgency and negative urgency (Short UPPS-P), problematic smartphone use (SPAI), and post-task smartphone-related thoughts.
  • Linear mixed-effects models in R (lme4/lmerTest) included condition, positive or negative urgency, their interaction, SPAI as a control, and participant as a random effect; model selection used AIC and Akaike weights, with post hoc tests via the phia package.

Limitations

  • Stated: the convenience sample of college students limits generalizability; self-report measures are partly flawed, especially for potentially stigmatized excessive phone use; emotional states were not manipulated or measured, so explanations involving positive and negative urgency remain tentative; other moderators such as fear of missing out were not tested; and the study was not preregistered.
  • Stated/paper-noted: the calculator condition may not have been an ideal control, because completely restricting smartphone access might have perturbed or distracted participants; the paper suggests future studies not use it as a control condition.
  • Evident: the final sample was predominantly female and restricted to young college students, so the findings may not extend to other age or gender groups.

  • The paper relies on this without support.

    Lower performance on the VWM task in a specific experimental condition indicates cognitive interference from smartphone availability.

    “Given the sensitivity of this measure, we reasoned that it is a relevant variable to test the postulated cognitive interference effect. Indeed, if performance on the VWM task is lower in a specific experimental condition, this would mean that the difference observed can be linked to a cognitive interference effect of smartphone availability.”
  • The paper relies on this without support.

    The three smartphone conditions (silent-mode, turned-off, calculator) validly manipulate smartphone availability as intended (high, low, no availability).

    “participants were exposed to various degrees of availability of their smartphones (high availability, low availability, no availability)”
  • The paper relies on this without support.

    The VWM task validly measures visual working memory capacity and attentional processes.

Statistics that don’t add up

Each reported p-value recomputed from its test statistic and degrees of freedom.

  • Inconsistent p-value: χ2 (2) = 5.12, p = .07

    Minor

    The paper reports p = .07 here; recomputing from the test statistic and its degrees of freedom gives p = .077. The check cannot tell whether the statistic or the p-value is the misprint.

    Reported p = .07 · recomputed p = .077

  • Inconsistent p-value: χ2 (1) = 0.68, p = .40

    Minor

    The paper reports p = .4 here; recomputing from the test statistic and its degrees of freedom gives p = .410. The check cannot tell whether the statistic or the p-value is the misprint.

    Reported p = .4 · recomputed p = .410

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-08.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-08.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
