From sensory processes to conscious perception

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging (fMRI) was used while testing subjects with a paradigm known as the "attentional blink." In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate (BA 32), medial prefrontal cortex (BA 9), and frontopolar cortex (BA 10) predicted whether or not information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing.     

A model for brief assessment of attachment and its application to women in inpatient treatment for trauma-related psychiatric disorders

We adapted self-report measures of attachment style to the psychological assessment of women in specialized inpatient treatment for trauma-related disorders. The study employed 2 measures of adult attachment style, the Relationship Questionnaire (Bartholomew & Horowitz, 1991) and the Adult Attachment Scale (Collins & Read, 1990) as well as our Current Attachment Relationships questionnaire, which assesses the extent of social support in secure attachments. We administered these measures to 99 patients and to a convenience sample of 154 women in the community. We found modest correspondence between the 2 attachment style measures and substantial relations between attachment styles and range of secure attachment relationships. Women in the trauma sample reported insecure attachment styles and relatively few secure attachment figures. We discuss the implications of these findings for clinical assessment.     

The conversion of Paul

This essay extrapolates from recent psychological data on the phenomena of guilt and splitting to possible implications for the understanding of the experience of the Apostle Paul.     

Eye contact facilitates awareness of faces during interocular suppression

Eye contact captures attention and receives prioritized visual processing. Here we asked whether eye contact might be processed outside conscious awareness. Faces with direct and averted gaze were rendered invisible using interocular suppression. In two experiments we found that faces with direct gaze overcame such suppression more rapidly than faces with averted gaze. Control experiments ruled out the influence of low-level stimulus differences and differential response criteria. These results indicate an enhanced unconscious representation of direct gaze, enabling the automatic and rapid detection of other individuals making eye contact with the observer.     

Coping with challenge and hindrance stressors in teams: Behavioral,cognitive, and affective outcomes

The purpose of this study was to utilize the challenge–hindrance framework to examine the discrete and combined effects of different environmental stressors on behavioral, cognitive, and affective outcomes at the team level. Results from 83 teams working on a command and control simulation indicated that the introduction of a challenge stressor positively affected team performance and transactive memory. The introduction of a hindrance stressor negatively affected team performance and transactive memory and positively affected psychological withdrawal. When the hindrance stressor was combined with the challenge stressor, teams exhibited the lowest levels of performance and transactive memory, and the highest levels of psychological withdrawal. These effects were due to the adoption of specific coping strategies by team members. Implications are discussed, as well as limitations and directions for future research.     

Trauma Exposure in Anxious Primary Care Patients

The present study examined rates of trauma exposure, clinical characteristics associated with trauma exposure, and the effect of trauma exposure on treatment outcome in a large sample of primary care patients without posttraumatic stress disorder (PTSD). Individuals without PTSD (N?=?1,263) treated as part of the CALM program (Roy-Byrne et al., Journal of the American Medical Association 303(19)1921–1928, 2010) were assessed for presence of trauma exposure. Those with and without trauma exposure were compared on baseline demographic and diagnostic information, symptom severity, and responder status six months after beginning treatment. Trauma-exposed individuals (N?=?662, 53 %) were more likely to meet diagnostic criteria for Obsessive Compulsive Disorder and had higher levels of somatic symptoms at baseline. Individuals with and without trauma exposure did not differ significantly on severity of anxiety, depression, or mental health functioning at baseline. Trauma exposure did not significantly impact treatment response. Findings suggest that adverse effects of trauma exposure in those without PTSD may include OCD and somatic anxiety symptoms. Treatment did not appear to be adversely impacted by trauma exposure. Thus, although trauma exposure is prevalent in primary care samples, results suggest that treatment of the presenting anxiety disorder is effective irrespective of trauma history.     

Developmental Changes in Content of Movement Responses

This study examines the relationship between Minnesota Multiphasic Personality Inventory-2 (MMPI-2) measured personality characteristics and marital distress and provides empirical validation for using the MMPI-2 with a marital therapy population. Studied were 150 couples in marital therapy and 841 normal couples who participated in the MMPI-2 restandardization study. The MMPI-2, a biographical form, a partner rating form, and the Dyadic Adjustment Scale (DAS) were administered to all couples. The marital counseling group resembled previous marital counseling samples studied with the MMPI and scored significantly higher than the normative sample on several MMPI-2 scales. Relationships between the DAS and MMPI-2 clinical and content scale scores are reported. The Psychopathic Deviate (Pd) clinical scale and Family Problems (FAM) content scale were the most powerful group discriminators and strongest correlates of the DAS; their use as indices of marital distress is tested. The meaning of Pd as an index in assessing personality factors in marital distress is explored.
