Selective attention and threat: quick orienting versus slow disengagement and two versions of the dot probe task.
نویسندگان
چکیده
The dot probe task is often used to assess attentional bias in anxiety, but some aspects need clarification. First, the results, which are traditionally summarized in an attentional bias index, do not allow for distinguishing between different selective attention processes; orienting and disengagement. Second, different versions of the dot probe task have been used with unknown relative merits. Participants (N=133) completed two versions of the dot probe task: the detection task (i.e. is there a probe?) and the differentiation task (i.e. what sort of probe is it?). The analysis carried out allowed for a differentiation between orienting and disengagement. The main finding was that trait anxiety is related to disengagement difficulties and not to speed of orienting. Concerning the relative merits of the two dot probe task versions, the results suggest that the detection task may be superior to the differentiation task. Implications for past and future research are discussed.

The orienting of spatial attention to backward masked fearful faces is associated with variation in the serotonin transporter gene.
Threat signals facilitate spatial attention, even when awareness of these signals has been restricted through the use of backward masking. However, unrestricted/unmasked threat cues tend to delay the disengagement of attention, whereas restricted/masked threat facilitates orienting, suggesting different underlying mechanisms. Within the general population, the serotonin transporter gene polymor...
متن کاملSelective attention to threat in the dot probe paradigm: differentiating vigilance and difficulty to disengage.
The dot probe task [J Abnorm Psychol 95 (1986) 15] is an often-used paradigm to investigate selective attention to threat. A facilitated response to probes that appear at the same location of threat information in comparison with responses to probes at the opposite location of threat information is interpreted as vigilance for threat. We argue that the findings in the dot probe paradigm are amb...
متن کاملSelective attention to threat versus reward: meta-analysis and neural-network modeling of the dot-probe task.
Two decades of research conducted to date has examined selective visual attention to threat and reward stimuli as a function of individual differences in anxiety using the dot-probe task. The present study tests a connectionist neural-network model of meta-analytic and key individual-study results derived from this literature. Attentional bias for threatening and reward-related stimuli is accou...
متن کاملAttending to the fear in your eyes: facilitated orienting and delayed disengagement.
Fearful facial expressions convey threat-related information and automatically elicit modulations in spatial attention. The eye-region appears to be a particularly important feature for recognising and responding to fearful faces. However, it is unknown as to whether or not fearful eyes initiate modulations in spatial attention. In the current study, three dot-probe experiments with fearful and...
متن کاملStimulus-Driven Attention, Threat Bias, and Sad Bias in Youth with a History of an Anxiety Disorder or Depression.
Attention biases towards threatening and sad stimuli are associated with pediatric anxiety and depression, respectively. The basic cognitive mechanisms associated with attention biases in youth, however, remain unclear. Here, we tested the hypothesis that threat bias (selective attention for threatening versus neutral stimuli) but not sad bias relies on stimulus-driven attention. We collected m...
