Explicit memory in anxiety disorders

Two experiments were conducted to study selective memory bias favoring anxiety-relevant materials in patients with anxiety disorders. In the 1st experiment, 32 patients with generalized anxiety disorder (GAD), 30 with social phobia (speaking anxiety), and 31 control participants incidentally learned GAD-relevant words, speech anxiety-relevant words, strongly pleasant words, and words with a neutral valence. Participants did not show any explicit memory bias for threatening materials. Thirty patients suffering from panic disorder (PD) with agoraphobia and 30 controls took part in the 2nd experiment. The design was similar to the 1st experiment. This time a highly specific selective memory bias for threatening words was found. Words describing symptoms of anxiety were better recalled by PD patients. Results are consistent with previous findings but are inexplicable by existing theories.     

Working memory(s).

Working memory is variously defined as a set of linked and interacting information processing components that maintain information in a short-term store (or retrieve information into that store) for the purpose of the active manipulation of the stored items. The purpose of the this Special Issue is to present data relevant to the question of the functional organization of working memory. In this Introduction we review the two models of working memory and suggest that some of the similarities may be more apparent than real. We further suggest that the two models describe different systems that are specialized for different kinds of stimuli and for different kinds of information processing.     

Maternal Control Behavior and Locus of Control: Examining Mechanisms in the Relation Between Maternal Anxiety Disorders and Anxiety Symptomatology in Children

This study tested components of a proposed model of child anxiety and examined the mediational roles of (1) maternal control behavior, (2) maternal external locus of control, and (3) child external locus of control in the association between maternal and child anxiety. Thirty-eight clinically anxious mothers and 37 nonanxious mothers participated along with one of their children aged 6 to 14 (52.0% female; 78.7% Caucasian). Path analysis indicated that the overall model fit the data very well. Analyses also indicated that child external locus of control mediated the associations between (1) maternal and child anxiety and (2) maternal control behavior and child anxiety. Maternal anxiety was not related to maternal control behavior and maternal external locus of control was not associated with child anxiety. Findings are discussed in the context of theoretical models (e.g., Chorpita and Barlow 1998) regarding the transmission of maternal anxiety to their children and the specific roles of maternal behavior and child locus of control.
