The identification of premorbid markers of risk for psychopathology is one of the most important challenges for present-day psychiatric research. This study focuses on behavioral vulnerability factors that contribute to the development of anxiety. Little is known about the role of aversive learning and generalization in the development of pathological(More)
We present a questionnaire – The Emotional Attentional Control Scale (eACS) – An adaptation of the original Attentional Control Scale (ACS) that assesses the voluntary control of attention. A low score on the ACS has been associated with high levels of anxiety and depression. As the ACS items are affectively neutral, some people scoring high on the ACS may(More)
Generalization of acquired responses appears to be a crucial, yet under investigated process in emotional disorders. Generalization occurs when a conditioned response is elicited by a stimulus different from the original conditioned stimulus. The expansion of complaints, often seen in emotional disorders, is at least in part due to processes of(More)
In a sample of adults diagnosed with major depressive disorder (N = 77), we examined the relationship between overgeneral autobiographical memory and childhood physical and sexual abuse. We hypothesised that childhood abuse would be related to retrieving fewer specific autobiographical memories, even after statistically covarying psychopathology-related(More)
Generalization on the basis of prior experience is a central feature of human and nonhuman behavior, and anomalies in generalization can give rise to a wide array of problems. For instance, elevated levels of generalization have been shown in individuals suffering from an anxiety disorder. Identifying the individual difference variables that influence the(More)
Associative learning plays an important role in the development of anxiety disorders, but a thorough understanding of the variables that impact such learning is still lacking. We investigated whether individual differences in autobiographical memory specificity are related to discrimination learning and generalization. In an associative learning task,(More)
The experience sampling method (ESM) is a structured diary method with high ecological validity, in that it accurately captures the everyday context of individuals through repeated measurements in naturalistic environments. Our main objective was to investigate the feasibility of using ESM in individuals with acquired brain injury (ABI). A second goal was(More)
Eye Movement Desensitization and Reprocessing (EMDR) therapy for posttraumatic stress disorder involves making eye movements (EMs) during recall of a traumatic image. Experimental studies have shown that the dual task decreases self-reported memory vividness and emotionality. However valuable, these data are prone to demand effects and little can be(More)
Hypothalamic-pituitary-adrenal (HPA) axis irregularities have been associated with several psychological disorders. Hence, the identification of individual difference variables that predict variations in HPA-axis activity represents an important challenge for psychiatric research. We investigated whether self-reported attentional control in emotionally(More)
