Effects of Spikes in the Price of Gasoline on Behavioral Intentions: A Mental Accounting Explanation

In recent years, gasoline prices have spiked in response to world events, only to fall again within weeks or months. Anecdotal evidence suggests that these price fluctuations have a substantial impact on consumers' planned spending and their overall perceptions of financial well‐being. We propose that consumers' behavioral intentions in response to these spikes are driven in part by how consumers mentally account for the fluctuations in gasoline prices. Specifically, we contend that people allocate sharp increases in the price per gallon of gasoline to a comprehensive mental account. As a result, such increases affect consumers' perceptions of their overall cost of living and have far‐reaching effects on their planned spending. These predictions are tested in three experiments. The paper concludes with the discussion of a theoretical and applied implications of the results. Copyright © 2011 John Wiley & Sons, Ltd.     

Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C): A Review of Molecular and Clinical Literature

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is heritable cardiomyopathy that may result in arrhythmia, heart failure, and sudden cardiac death (SCD). Approximately 50-60% of ARVD/C patient will have an identifiable pathogenic mutation in one of seven genes associated with the cardiac desmosome and other cardiac pathways. Genetic counseling remains complicated, however, because of great variable expressivity and reduced penetrance, even within members of the same family. Diagnosis of ARVD/C is made by meeting a set of major and minor diagnostic criteria, revised in 2010. Despite this, misdiagnosis is a chronic problem. Management of ARVD/C is aimed at reducing risk of sudden death/arrhythmias and preventing progression of disease. Strenuous physical activity is increasingly recognized as a significant risk factor in disease presentation and progression and is an important factor in preventative management. Anticipation of the psychosocial implications of this disease is also an important aspect of patient management. This review presents an overview of the clinical diagnosis, management, as well as disease mechanism and genetics of this rare cardiomyopathy.     

Spatial coordinates and reading: Comments on Monk (1985)

Subjects are able to process some texts when they are presented, word-by-word, in a single physical location. As differential spatial information is not available in this task, Monk (1985a) argues that it need not be derived in normal reading. We suggest this conclusion is unwarranted, because subjects make large and very accurate regressive saccades to regions of previously fixated text. Without a representation of spatial coordinates this should not occur.     

Neurocognitive Function and Suicide in U.S. Army Soldiers

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk.     

Mental Disorders,Comorbidity, and Pre‐enlistment Suicidal Behavior Among New Soldiers in the U.S. Army: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS; N = 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts.     

Children's judgments about their own self‐knowledge: The role of disclosure to other

Previous research has suggested that children of 5/6 years fail to understand that they are the authority on their own self‐knowledge. That is, when asked questions like, ‘Who knows best when you are feeling tired?’, they tend to cite their mother rather than themselves. Here we report a study that, rather than asking about generalities (‘Who knows best what you are thinking?’), presented 5‐, 7‐ 9‐ and 11‐year‐children with hypothetical vignettes about specific circumstances in which they were described as either disclosing or not disclosing a specified state to their mother. Children were subsequently asked to judge who would best know the state. Over all age groups children were significantly more likely to identify themselves as authorities on their own self‐knowledge when states had not been disclosed to mother than when they had. However, in the case of disclosed states, young children (though not older ones) asserted that, ‘mum knows best’. These findings are interpreted as suggesting not that young children entirely fail to understand first person authority, but instead that they make the relatively sophisticated assumption that mothers' interpretive competence is greater than their own.
