Predicting posttraumatic growth among Hurricane Katrina survivors living with HIV: the role of self-efficacy,social support,and PTSD symptoms

Abstract

The study tested the model of adaptation after trauma by Benight and Bandura (2004) indicating that posttraumatic recovery may be predicted directly by coping self-efficacy (CSE) and indirectly by social support. These relations were investigated in the context of posttraumatic growth (PTG) among Hurricane Katrina survivors living with HIV. Additionally, it was hypothesized that among individuals with more intensive Posttraumatic Stress Disorder (PTSD) symptoms, those with strong CSE would experience the strongest PTG. Cross-sectional data were collected among 90 patients with HIV who reinitiated care at the HIV outpatient clinic. Questionnaires were administered approximately 14 months after the hurricane. Higher CSE was related to higher PTG among the survivors who suffered from more intensive PTSD symptoms. Received social support was directly related to only one index of PTG, relating to others. Furthermore, although there was a significant relationship between social support and CSE, the indirect conditional effect of received social support on PTG was not confirmed. Similar results were obtained across the indices of PTG, controlling for the level of exposure to hurricane-related trauma. Cross-sectional design and convenience character of the sample warrants replications.     

Attributions for Different Types of Traumatic Events and Post-Traumatic Stress Among Women

This study investigated the relationship of attributions to post-traumatic stress symptoms among women exposed to different types of traumatic events. Participants were 424 female undergraduates who previously experienced a serious accident, natural disaster, child abuse, or adult interpersonal violence. Path analysis indicated a significant indirect pathway from event type to post-traumatic stress through global attributions. Interpersonal-violence survivors exhibited the highest levels of global attributions and post-traumatic stress symptoms. Regression analyses revealed significant interactions between event type and attributions in predicting post-traumatic stress. Stable attributions were associated with increased symptoms in sexual-assault survivors and decreased symptoms in natural-disaster survivors. These findings have implications for improving cognitive interventions for survivors of different types of traumatic events.     

Iconic memory for natural scenes: Evidence using a modified change-detection procedure

ABSTRACT

Change blindness for the contents of natural scenes suggests that only items that are attended while the scene is still visible are stored, leading some to characterize our visual experiences as sparse. Experiments on iconic memory for arrays of discrete symbols or objects, however, indicate observers have access to more visual information for at least several hundred milliseconds at offset of a display. In the experiment presented here, we demonstrate an iconic memory for complex natural or real-world scenes. Using a modified change detection task in which to-be changed objects are cued at offset of the scene, we show that more information from a natural scene is briefly stored than change blindness predicts and more than is contained in visual short-term memory. In our experiment, a cue appearing 0, 300, or 1000?msec after offset of the pre-change scene or at onset of the second scene presentation (a Post Cue) directed attention to the location of a possible change. Compared to a no-cue condition, subjects were significantly better at detecting changes and identifying what changed in the cue condition, with the cue having a diminishing effect as a function of time and no effect when its onset coincided with that of the second scene presentation. The results suggest that an iconic memory of a natural scene exists for at least 1000?msec after scene offset, from which subjects can access the identity of items in the pre-change scene. This implies that change blindness underestimates the amount of information available to the visual system from a brief glance of a natural scene.     

The influence of situational and personal variables on the effectiveness of social support during childbirth

Abstract

This study examined the proposition that the efficacy of social support depends upon situational and personality variables. Specifically, it was hypothesized that women high on trait anxiety or undergoing their first experience of childbirth, would profit more from the presence of the husband during delivery than women low on trait anxiety or who had previously given birth. One hundred and twenty new mothers were asked to rank the level of state anxiety, state anger, tension and pain they had experienced during childbirth. Changes in their blood pressure and the amount of tranquilizing medication they had received were also measured. Results obtained with negative affectivity measures almost fully confirmed the hypotheses. Hypotheses regarding blood pressure were confirmed in part, but no support was found when using pain level and amount of tranquilizing medication as dependent variables. The findings are discussed in relation to the stress-buffering hypothesis and the manner in which trait anxiety might mediate the relationship between level of social support and individuals' stress reactions.     

Translating Cognition Into Action

This experiment examined the role of two forms of visual guidance in facilitating the translation of cognitive representations into action. Subjects matched a modeled action pattern either concurrently with the model or after the modeled display. They then either did or did not visually monitor their actions during tests of production accuracy in the model’s absence. Acquisition of the cognitive representation was assessed periodically. Concurrent matching of modeled actions or visual monitoring of productions both increased the level of observational learning. The more accurate the cognitive representation, the more skilled were subsequent reproductions of the modeled actions. After acquiring proficiency in converting cognition to action, subjects maintained their level of performance accuracy even though modeled and visual-monitoring guidance were withdrawn. These results are in accordance with the theory that cognitive representation mediates response production and that corrective adjustments through visual guidance aid in the translation of conception into action.     

Reconsidering the concept of theodicy in the context of the post-2011 Japanese earthquake and tsunami

Has the 2011 Tohoku Earthquake given rise to theodicy in Japan? This question would puzzle many scholars of religion for two major reasons. First, theodicy has generally been regarded as an outdated concept, and it is rare to see a lively discussion of it in today's academia except for in theology. Second, typical theodicean questions are unlikely to be asked publicly in Japan, where less than 2 percent of the population follow monotheistic traditions. Despite these assumptions, this article not only reports that ‘apparently’ theodicean public discourses have emerged since the 11 March earthquake, but also attempts to employ the typology of theodicy to analyze them in a thought-provoking and critical manner. It argues that the post-3/11 Japanese voices, which regard the disaster as a divine punishment, use a reverse logic of traditional Western theodicy. Rather than signaling a sudden turn to monotheism, the voices are inclined to imply nativism.     

Theological Influences in Scientific Research Programs: Natural Theology “in Reverse”

The Boyle Lectures were created to promote natural theology, where science leads to belief in God. Russell's 2017 Boyle Lecture moves in the ‘opposite’ direction, showing how theological convictions held, often implicitly, by research scientists can play a creative role in both the construction of scientific theories and the choice between existing theories. As examples, Russell explores the conflicts over Big Bang versus Steady-State cosmologies, and between Einstein and Bohr about quantum mechanics. Against the claim that these influences die off once the conflict is over, Russell shows that they continue to be inherited by successive generations of scientists.     

Naturalisms: Scientific? Religious? Theological?

Is nature all there is? Or, is there more? If nature is the only reality, is it ultimate or sacred? Differing answers to these questions determine the different brands of naturalism on the religious shelf. What virtually all of today’s naturalists agree on is this: science provides the means for revealing reality, the sole reality which is material, physical, and cosmic. Naturalists also agree that supranaturalism should be rejected. What naturalists differ on whether nature is divine or not. This article sorts out the issues and differing positions taken on each issue. The author contends that a post-Newtonian worldview remains open to a concept of God wherein divine action in nature’s world influences creativity and transformation.
