Information processing and negative affect: evidence from the 2003 Health Information National Trends Survey.

OBJECTIVE: Health communication can help reduce the cancer burden by increasing processing of information about health interventions. Negative affect is associated with information processing and may be a barrier to successful health communication. DESIGN AND MAIN OUTCOME MEASURES: We examined associations between negative affect and information processing at the population level. Symptoms of depression (6 items) and cancer worry (1 item) operationalized negative affect; attention to health information (5 items) and cancer information-seeking experiences (6 items) operationalized information processing. RESULTS: Higher cancer worry was associated with more attention to health information (p<.01) and worse cancer information-seeking experiences (p<.05). More symptoms of depression were associated with worse information-seeking experiences (p<.01), but not with attention. CONCLUSIONS: We found population-level evidence that increased cancer worry is associated with more attention to health information, and increased cancer worry and symptoms of depression are associated with worse cancer information-seeking experiences. Results suggest that affect plays a role in health information processing, and decreasing negative affect associated with cancer communication may improve experiences seeking cancer information.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

Assessing the costs and benefits of production in recognition

The production effect is a memory advantage for items studied aloud over items studied silently. Although it typically is found within subjects, here we also obtained it between subjects in a recognition task—providing new evidence that production can be an effective study strategy. Our experiment, and a set of meta-analyses, also evaluated whether the within effect reflects costs to silent items and/or benefits to aloud items. Contrary to a strong distinctiveness account, we found little evidence that aloud items show an additional within-subjects benefit. Instead, silent items suffered an additional within-subjects cost. Blocking silent and aloud items eliminated this cost, suggesting that the cost was due to mixing silent and aloud items. Our discussion focuses on implications for distinctiveness and strength accounts of the production effect and on how to implement production as an encoding strategy depending on the learner’s goals.     

Service Learning in Light of Emmanuel Levinas

Emmanuel Levinas, a twentieth century French Continental philosopher, proposed an original understanding of ethics which has serious implications for the particular activities within higher education designated as service learning and community service. First I will define service learning and community service and briefly review the theoretical and philosophical justifications typically employed to substantiate and ground these activities within higher education. Next, I will explicate key aspects from Levinas’ ethical philosophy important for reconceptualizing service learning, and discuss their significance for related concerns in higher education about language and justice. Finally, in light of these considerations, I will suggest the profound implications of a Levinasian conception of service for higher education.     

Reducing the Misinformation Effect Through Initial Testing: Take Two Tests and Recall Me in the Morning?

Initial retrieval of an event can reduce people's susceptibility to misinformation. We explored whether protective effects of initial testing could be obtained on final free recall and source‐monitoring tests. After studying six household scenes (e.g., a bathroom), participants attempted to recall items from the scenes zero, one, or two times. Immediately or after a 48‐hour delay, non‐presented items (e.g., soap and toothbrush) were exposed zero, one, or four times through a social contagion manipulation in which participants reviewed sets of recall tests ostensibly provided by other participants. A protective effect of testing emerged on a final free recall test following the delay and on a final source‐memory test regardless of delay. Taking two initial tests did not increase these protective effects. Determining whether initial testing will have protective (versus harmful) effects on memory has important practical implications for interviewing eyewitnesses. © 2015 The Authors.

Psychological Predictors of Neurobehavioral Symptoms in a Polytrauma Veteran Sample

Given the high prevalence of comorbid conditions found in polytrauma settings, effective screening measures are needed. Several screening tools are commonly used in polytrauma clinics within the Department of Veterans Affairs (VA). This study examined the use of three screening measures—the Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and PTSD Checklist–Civilian Version (PCL-C)—to predict scores on the Neurobehavioral Symptom Inventory (NSI). Research suggests that the presence of mental health conditions, such as PTSD, shares a significant amount of variance with postconcussive symptoms. The investigators hypothesized that the PCL-C would be the best predictor of scores on the NSI. All subjects were administered the screening measures as part of an evaluation in an outpatient Level III polytrauma clinic. Regression analysis was used to determine which instrument might serve as the best predictor of NSI total scores. Regression analysis revealed that BAI, BDI-II, and PCL-C total scores were good predictors of NSI total scores, with the BAI accounting for the majority of the variance. Mental health conditions can account for higher scores on the NSI, and screening of other mental health conditions should be taken into account when reviewing the NSI for individuals in polytrauma settings.
