Biases in attention, interpretation, memory, and associations in children with varying levels of spider fear: Inter-relations and prediction of behavior

Highlights

  • Cognitive biases each predict unique variance in spider fear-related behavior.

  • Interpretation bias and fear-related associations remained significant predictors.

  • Even when self-reported fear was included as a predictor.

  • The cognitive bias tasks only showed little overlap.

Abstract

Background and Objectives

Cognitive theories suggest that cognitive biases may be related and together influence the anxiety response. However, little is known about the interrelations of cognitive bias tasks and whether they allow for an improved prediction of fear-related behavior in addition to self-reports. This study simultaneously addressed several types of cognitive biases in children, to investigate attention bias, interpretation bias, memory bias and fear-related associations, their interrelations and the prediction of behavior.

Methods

Eighty-one children varying in their levels of spider fear completed the Spider Anxiety and Disgust Screening for Children and performed two Emotional Stroop tasks, a Free Recall task, an interpretation task including size and distance indication, an Affective Priming Task, and a Behavioral Assessment Test.

Results

We found an attention bias, interpretation bias, and fear-related associations, but no evidence for a memory bias. The biases showed little overlap. Attention bias, interpretation bias, and fear-related associations predicted unique variance in avoidance of spiders. Interpretation bias and fear-related associations remained significant predictors, even when self-reported fear was included as a predictor.

Limitations

Children were not seeking help for their spider fear and were not tested on clinical levels of spider phobia.

Conclusions

This is the first study to find evidence that different cognitive biases each predict unique variance in avoidance behavior. Furthermore, it is also the first study in which we found evidence for a relation between fear of spiders and size and distance indication. We showed that this bias is distinct from other cognitive biases.

Participants

The current study was part of a large community-based project on childhood anxiety. After parental consent had been granted, a total of 718 children were screened on anxiety in their regular classroom environment. Approximately two months after initial screening, 95 children were invited to participate in this study. The children who participated in this study also participated in another study about social anxiety and were therefore pre-selected on levels of social anxiety. The data of 14

Emotional Stroop tasks (EST)

The overall number of mistakes was low, for both the EST-picture (0.8%) and the EST-word (0.5%). From the EST-picture card RTs and the EST-word card RTs, two relative scores related to spiders were computed; that is, the EST-picture score (RT-Spider minus RT-Neutral) and the EST-word score (RT-Spider minus RT-Neutral). Higher scores indicate larger distraction by the spider category. Two one-sample t-tests revealed that children did not show significant distraction specifically related to

Discussion

This study is the first to combine attention bias, interpretation bias, memory bias, and fear-related associations, to examine their inter-relations and to test the independent ability of these biases to predict avoidance of spiders in children. The first goal of this study was to replicate the findings of the current study to earlier studies by Klein et al., 2011, Klein et al., 2012. Consistent with our earlier results, we found that spider-fearful children displayed both attention bias and
