Maternal modeling and the acquisition of fear and avoidance in toddlers: influence of stimulus preparedness and child temperament.

The aim of the present study was to investigate the influence of maternal modeling on the acquisition of fear and avoidance towards fear-relevant and fear-irrelevant, novel stimuli in a sample of 71 toddlers. Children were shown a rubber snake or spider (fear-relevant objects) and a rubber mushroom or flower (fear-irrelevant objects), which were alternately paired with either negative or positive expression by their mothers. Both stimuli were presented again after a 1- and a 10-min delay, while mothers maintained a neutral expression. The toddlers showed increased fear and avoidance of the objects following negative reaction from their mothers than following positive maternal expression. This was similarly true for both fear-relevant and fear-irrelevant stimuli. In addition, no association was found between child temperament and behavioral responses and a weak association emerged between child temperament and emotional responses. The results demonstrate that young children can rapidly form conditioned emotional and behavioral responses via maternal reactions regardless of stimulus preparedness or child temperament. It is suggested that early maternal modeling may be relevant to a broad spectrum of fearful reactions.

The Picture Anxiety Test (PAT): a new pictorial assessment of anxiety symptoms in young children.

This study examines the psychometric properties of a newly developed pictorial anxiety assessment, the Picture Anxiety Test (PAT), designed for young children. A sample of 71 5-7-year-old children (clinically anxious and healthy controls) participated in an assessment comparing the PAT to other, established anxiety measures. Children's ratings were also compared to parent ratings of internalizing and externalizing problems. The PAT demonstrated favorable psychometric properties in this sample, including moderate to high internal consistency, high convergent validity with related constructs, and high discriminant validity between diagnostic groups and across pre- and post-treatment. Initial findings suggest that the PAT is a psychometrically sound instrument for assessing child anxiety and avoidance in young children and a valuable addition to existing diagnostic instruments for clinicians working with anxious children.

Forced choice reaction time paradigm in children with separation anxiety disorder, social phobia, and nonanxious controls.

Cognitive distortions refer to cognitive processes that are biased and therefore yield dysfunctional and maladaptive products (e.g., interpretation bias). Automatic aspects of information processing need to be considered and investigating these aspects requires forms of assessment other than self-report. Studies focussing on the specificity of cognitive biases across different types of anxiety disorders in childhood are rare. Thus, a forced choice reaction time paradigm with picture stimuli was used to assess the interpretation bias in anxious children online. The study investigated disorder-specific interpretation bias in 71 children with separation anxiety disorder (SAD), 31 children with social phobia, and 42 children without mental disorders, aged 5-13 years. Results indicated that children with SAD rated ambiguous separation pictures as significantly more unpleasant and more arousing than nonanxious children. However, no support was found that children with SAD and social phobia interpret ambiguous separation or social pictures in a more negative way than nonanxious children. Furthermore, no group differences were found in reaction times to all picture categories.
