Attentional Bias
The selective allocation of attention toward certain types of information (especially threat-related stimuli) at the expense of other information.
Forty marks, one distinct — your eye reached it first, and your memory will too.
Why the standout sticks
Attentional bias in anxiety is thought to reflect automatic orienting toward threat-relevant stimuli, possibly driven by amygdala activity. The dot-probe task measures relative speeding to probes at threat locations, which may indicate either faster engagement with threat or slower disengagement from it. Beck's cognitive model posits that anxious individuals have threat-relevant schemas that direct attentional resources toward schema-congruent stimuli. The bias appears to operate at both pre-conscious (subliminal) and conscious (supraliminal) levels.
Competing account — There is debate about whether the dot-prope bias index reflects vigilance (orienting toward threat), difficulty disengaging from threat, or both. Some evidence suggests these components can be separated.
What the trials measured
GAD patients were faster to respond to probes replacing threat words than neutral words, indicating an attentional bias toward threat. Control participants showed no such bias.
MacLeod, Mathews & Tata · 1986 · n = 24 (12 GAD patients, 12 controls)
Participants trained to attend to neutral stimuli showed reduced anxiety reactivity to stress compared to those trained to attend to threat, suggesting attentional bias causally influences anxiety vulnerability.
MacLeod, Rutherford, Campbell, Ebsworthy & Holker · 2002 · n = 80 undergraduate students
Overall post-intervention effect size was g = 0.26 (small). Effect was moderated by anxiety type: GAD showed g = 0.61 (moderate), social anxiety g = 0.24 (small), and phobias/PTSD g = 0.16 (non-significant).
Mogoase, David & Koster · 2014 · 22 studies meta-analyzed
Distinctiveness — mixed. The basic finding that anxious individuals show attentional bias toward threat has been replicated hundreds of times and confirmed by meta-analysis. However, attentional bias modification (ABM) training as a clinical intervention has shown inconsistent results: a 2014 meta-analysis found a small overall effect moderated by anxiety type, and some registered replications have failed to find significant effects.

Anxiety disorders clinical assessment using dot-probe
The dot-probe task is routinely used in clinical psychology to assess attentional bias in anxiety disorders. Patients with GAD, social anxiety, PTSD, and panic disorder consistently show threat-related biases, which are targeted in cognitive-behavioral therapy.

Cognitive-behavioral therapy for anxiety modifies attentional patterns
CBT for anxiety, which has strong evidence of efficacy, includes techniques to redirect attention away from threat cues. Studies show that successful CBT can reduce attentional bias scores on the dot-probe task.
To weight it fairly
Attentional Bias Modification (ABM) training using the dot-probe task to redirect attention away from threat and toward neutral stimuli. Also, mindfulness and cognitive restructuring can help redirect attention.
Meta-analyses show small but significant effects of ABM on anxiety symptoms, with larger effects for generalized anxiety. However, replication is mixed and ABM is not yet standard clinical practice.
Catch it in the act
A person with social anxiety finds their eyes drawn to critical faces in a crowd and misses neutral or friendly expressions; a smoker notices cigarette packs more than non-smokers; a worried patient fixates on rare side-effects mentioned by a doctor.

- Confirmation BiassiblingBoth involve selective information processing, but confirmation bias operates at the level of belief evaluation while attentional bias operates at the pre-conscious allocation of attention.
- Probability Neglectmechanistically-linkedBoth are linked to anxiety; attentional bias involves what information is selected, while probability neglect involves distorted weighting of risk magnitude.
