The role of controlled attention on recall in major depression

Information processing biases are hallmark features of major depressive disorder (MDD). Depressed individuals display biased memory and attention for negative material. Given that memory is highly dependent on attention for initial encoding, understanding the interplay of these processes may provide important insight into mechanisms that produce memory biases in depression. In particular, attentional control—the ability to selectively attend to task-relevant information by both inhibiting the processing of irrelevant information and disengaging attention from irrelevant material—may be one area of impairment in MDD. In the current study, clinically depressed (MDD: n = 15) and never depressed (non-MDD: n = 22) participants' line of visual gaze was assessed while participants viewed positive and negative word pairs. For each word pair, participants were instructed to attend to one word (target) and ignore one word (distracter). Free recall of study stimuli was then assessed. Depressed individuals displayed greater recall of negatively valenced target words following the task. Although there were no group differences in attentional control in the context of negative words, attention to negative targets mediated the relationship between depression status and recall of negative words. Results suggest a stronger link between attention and memory for negative material in MDD.     

The Effects of Work-Related and Boundary-Related Stress on the Emotional and Physical Health Status of Ordained Clergy

This research is the second component of a three-part series that explores the relationship between stress and health in the clerical profession. The first article (Wells, Journal of Religion and Health 51(1):215–30, 2012) determined that there is an association between two different sources of stress in the clerical profession (work-related stress and boundary-related stress). This research explores the association between these two sources of stress and two different measures of health (emotional health and physical health). Utilizing the same dataset from the previous research (Wells, Journal of Religion and Health 51(1):215–30, 2012), and simple and multiple regression, this research determined that there is a positive association between the two sources of stress (work-related stress and boundary-related stress) and the two measures of health (physical health and emotional health). African-American and obese clergy exhibited lower levels of physical health as stress increased. Clergy with children and those with higher levels of education exhibited lower levels of emotional health as stress increased. African-American clergy consistently exhibited higher levels of emotional health than their White colleagues did. Finally, age and length of time in ministry are associated with higher levels of emotional health but lower physical health status.     

A multi-dimensional measure of worry: Development and preliminary validation of the anxious thoughts inventory

This paper reports the development of a dispositional self-report measure of multiple dimensions of generalised worry. Factor analyses demonstrated a replicable three factor structure indicating that this measure of worry comprises three basic dimensions: social worry, health worry, and meta-worry. The first two factors reflect different content dimensions whereas the meta-worry factor consists of both content and process dimensions of worry. Individual differences in subscale scores show moderate stability over time, and the subscales possess good psychometric properties. Significant correlations were found between worry subscales and personality dimensions of self-consciousness and EPI scores. The role of multi-dimensional measurement in the exploration of worry is discussed.     

Metacognitive Therapy for Generalized Anxiety Disorder: Nature,Evidence and an Individual Case Illustration

Metacognitive therapy (MCT) is based on over 25 years of research focusing on the processes that contribute to the development and maintenance of psychological disorders. The approach identifies a common set of processes in psychopathology, and MCT shows promising results in effectively treating a range of disorders. This paper presents the central theoretical tenets of MCT and uses a clinical vignette to illustrate the structure and techniques of treatment based on Wells's (2009) manual as they relate to a specific case of generalized anxiety disorder.     

Turing's Analysis of Computation and Theories of Cognitive Architecture

Turing's analysis of computation is a fundamental part of the background of cognitive science. In this paper it is argued that a re-interpretation of Turing's work is required to underpin theorizing about cognitive architecture. It is claimed that the symbol systems view of the mind, which is the conventional way of understanding how Turing's work impacts on cognitive science, is deeply flawed. There is an alternative interpretation that is more faithful to Turing's original insights, avoids the criticisms made of the symbol systems approach and is compatible with the growing interest in agent-environment interaction. It is argued that this interpretation should form the basis for theories of cognitive architecture.     

Myths and Small Groups: Development, Managed Care, and the Year 2000

In this article, the author defines myth and shows that disguised myths of archaic and primitive peoples can be found in the modern world. He discusses the myths that guide the development of small groups. He sketches out mythic aspects of the encounter between group therapy and managed care. Finally, he suggests the mythic significance of the year 2000 for the future of group development and of group therapy.     

What’s in a voice? Dolphins do not use voice cues for individual recognition

Most mammals can accomplish acoustic recognition of other individuals by means of “voice cues,” whereby characteristics of the vocal tract render vocalizations of an individual uniquely identifiable. However, sound production in dolphins takes place in gas-filled nasal sacs that are affected by pressure changes, potentially resulting in a lack of reliable voice cues. It is well known that bottlenose dolphins learn to produce individually distinctive signature whistles for individual recognition, but it is not known whether they may also use voice cues. To investigate this question, we played back non-signature whistles to wild dolphins during brief capture-release events in Sarasota Bay, Florida. We hypothesized that non-signature whistles, which have varied contours that can be shared among individuals, would be recognizable to dolphins only if they contained voice cues. Following established methodology used in two previous sets of playback experiments, we found that dolphins did not respond differentially to non-signature whistles of close relatives versus known unrelated individuals. In contrast, our previous studies showed that in an identical context, dolphins reacted strongly to hearing the signature whistle or even a synthetic version of the signature whistle of a close relative. Thus, we conclude that dolphins likely do not use voice cues to identify individuals. The low reliability of voice cues and the need for individual recognition were likely strong selective forces in the evolution of vocal learning in dolphins.
