Altered working memory capacity for social threat words in high versus low social anxiety

ABSTRACT

Background and objectives: Differences in working memory capacity (WMC) have been suggested in individuals with high levels of social anxiety (SA). Specifically, these individuals may preferentially maintain socially threatening material in working memory.

Design and methods: We adapted the digit span task to a series of word span tasks. We assessed WMC for lists of words that varied in terms of their threat-relatedness, in individuals either high or low in SA.

Results: Experiment 1 revealed reduced WMC for socially threatening words in those with high compared to low SA. Importantly, this relative reduction in WMC was driven by the low SA group showing expanded capacity for socially threatening words relative to neutral or generally threatening words. Furthermore, reductions in WMC for social threat were uniquely predicted by SA, and not by other theoretically related constructs such as state general anxiety, trait general anxiety, or depression. Experiment 2 showed that the semantic similarity of the words within each list was not responsible for the differences in WMC between list type or SA group.

Conclusions: Our findings suggest that individuals high in SA may fail to upregulate WMC for social information due to the activation of, or rumination upon, socially threatening concepts.     

What’s left? An eye movement study of the influence of interword spaces to the left of fixation during reading

In English and other alphabetic systems read from left to right, the useful information acquired during each fixational pause is generally reported to extend 14–15 character spaces to the right of each fixation, but only 3–4 character spaces to the left, and certainly no farther than the beginning of the fixated word. However, this leftward extent is remarkably small and seems inconsistent with the general bilateral symmetry of vision. Accordingly, in the present study we investigated the influence of a fundamental component of text to the left of fixation—interword spaces—using a well-established eyetracking paradigm in which invisible boundaries were set up along individual sentence displays that were then read. Each boundary corresponded to the leftmost edge of a word in a sentence, so that as the eyes crossed a boundary, interword spaces in the text to the left of that word were obscured (by inserting a letter x). The proximity of the obscured text during each fixational pause was maintained at one, two, three, or four interword spaces from the left boundary of each fixated word. Normal fixations, regressions, and progressive saccades were disrupted when the obscured text was up to three interword spaces (an average of over 12 character spaces) away from the fixated word, while four interword spaces away produced no disruption. These findings suggest that influential information from text is acquired during each fixational pause from much farther leftward than is generally realized and that this information contributes to normal reading performance. Implications of these findings for reading are discussed.     

Frequency and Impact of Interpersonal Trauma in Older Women

Interpersonal violence impacts the lives of many women in society. However, despite the proliferation of research in this area, there is limited information about the frequency and impact of interpersonal trauma experiences in late life. This study investigated the relationship between a history of interpersonal trauma and subsequent adjustment difficulties, including psychological distress and physical health, in women over the age of 60. Findings demonstrate that interpersonal trauma has a significant impact on later-life functioning. Additionally, the presence of multiple traumatization experiences was a critical factor in determining which individuals manifested long-term trauma symptoms.     

Modification of Cognitive-Behavioral Techniques in the Treatment of a Five Year-Old Girl with Social Phobia

Social phobia is a debilitating anxiety disorder that often goes undetected in young children, but can be effectively treated with cognitive-behavioral interventions. For children and adolescents, treatment usually includes education, social skills training, cognitive restructuring, relaxation training, and exposure. However, for very young children who present with social phobia, it is necessary to adapt treatment to the developmental level of the child. A case illustration demonstrates the way in which cognitive behavioral treatment (CBT) was modified for the treatment of a five year-old girl with social phobia. Several modifications were made, including utilizing novel exposure techniques and emphasizing parent management training in order to promote generalization of treatment gains outside of session.
