Inverse reference in subtraction performance: An analysis from arithmetic word problems

Studies of elementary calculation have shown that adults solve basic subtraction problems faster with problems presented in addition format (e.g., 6?+?_?=?13) than in standard subtraction format (e.g., 13 – 6?=?_). Therefore, it is considered that adults solve subtraction problems by reference to the inverse operation (e.g., for 13 – 6?=?7, “I know that 13 is 6?+?7”) because presenting the subtraction problem in addition format does not require the mental rearrangement of the problem elements into the addition format. In two experiments, we examine whether adults' use of addition to solve subtractions is modulated by the arrangement of minuend and subtrahend, regardless of format. To this end, we used arithmetic word problems since single-digit problems in subtraction format would not allow the subtrahend to appear before the minuend. In Experiment 1, subtractions were presented by arranging minuend and subtrahend according to previous research. In Experiment 2, operands were reversed. The overall results showed that participants benefited from word problems where the subtrahend appears before the minuend, including subtractions in standard subtraction format. These findings add to a growing body of literature that emphasizes the role of inverse reference in adults' performance on subtractions.

Perceptions of Liver Transplant Candidates with or Without an Alcohol Use History

Cirrhosis secondary to alcohol use is a primary cause of liver disease and a medical condition for which liver transplantation is a viable treatment option. However, there remains considerable debate within both the lay and the medical communities regarding the distribution of a scarce medical resource to adults with alcoholism. This study examined college students' perceptions toward an adult, presented in a written vignette, for whom liver transplantation was medically indicated. The influence of gender (female and male) and alcohol use history (no alcohol history, alcoholism history with long-term abstinence, alcoholism history with current use) on these ratings was examined. Subjects rated the adult presented with no alcohol history more positively than they did the adults presented with a history of alcoholism. Also, the adult with no alcohol history was more likely to be offered transplantation and was given higher priority ratings for transplantation by subjects. While subjects' own alcohol use history and organ donor registration status were not associated with ratings, having a family member with an alcohol problem and personally knowing a transplant recipient were related to more favorable ratings toward the adult presented in the vignette. Implications of these findings as well as limitations of the study are discussed.     

Long Term Outcomes to Family Caregiver Empowerment

The Vanderbilt Caregiver Empowerment Project evaluated a training program designed to enhance empowerment of caregiver and their subsequent involvement in the mental health treatment of their children. The intervention utilized a multi-component parent training curriculum that was designed to enhance: (a) knowledge of the service system; (b) skills needed to interact with the mental health system; and (c) the caregiver' s mental health services self-efficacy designed to improve caregivers beliefs in their ability to collaborate with service providers. The resulting increased empowerment was hypothesized to increase caretaker involvement, which should affect service use and ultimately the mental health status of the child. A randomized design was used to test the effectiveness of this model with caregivers of children receiving mental health services. The results one-year after the training replicated the intermediate outcomes of the project conducted 3-months after the training. The initial training continued to significantly influence the parent's knowledge and mental health services self-efficacy. However, the intervention had no effect on caregiver involvement in treatment, service use or the mental health status of the children.     

THE USE OF THE ANALYST AND THE SENSE OF BEING REAL: THE CLINICAL MEANING OF WINNICOTT'S “THE USE OF AN OBJECT”

“The Use of an Object and Relating through Identifications” (1968) represents Donald Winnicott's theoretical and clinical legacy. The author develops this concept from a clinical point of view, through the analysis of a woman with psychotic functioning. He reflects upon the dramatic quality of risks inherent in the processes linked to the use of the object with seriously disturbed patients. He explores different meanings of the analyst's survival, linking it to the analyst's response. The processes of the use of the object—that is, the encounter between the patient's potential destructiveness and the analyst's capacity to respond through his own judicious subjectivity—let the patient experience the analyst's capacity to keep his own subjectivity, authenticity, and creativity alive. It is starting from the traces of this live object that patients gradually form their own personal sense of being real.     

Best Practices Start With Screening: A Closer Look at Screening,Brief Intervention,and Referral to Treatment in Adolescent,Military, and LGBTQ Populations

Screening, brief intervention, and referral to treatment (SBIRT) is a flexible, evidence‐based approach to assessing risk and providing brief interventions for individuals with alcohol use disorders. This article identifies 3 diverse populations that could benefit from universal screening—a foundation of SBIRT—and provides resources and support for implementation across a broad range of settings.     

School Substance Use Norms and Racial Composition Moderate Parental and Peer Influences on Adolescent Substance Use

Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid‐western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school‐level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School‐level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school‐level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use.     

Drugs,Sex, and Condoms: Identification and Interpretation of Race‐Specific Cultural Messages Influencing Black Gay and Bisexual Young Men Living with HIV

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being.     

Tool use in left brain damage and Alzheimer's disease: What about function and manipulation knowledge?

Tool use disorders are usually associated with difficulties in retrieving function and manipulation knowledge. Here, we investigate tool use (Real Tool Use, RTU), function (Functional Association, FA) and manipulation knowledge (Gesture Recognition, GR) in 17 left‐brain‐damaged (LBD) patients and 14 AD patients (Alzheimer disease). LBD group exhibited predicted deficit on RTU but not on FA and GR while AD patients showed deficits on GR and FA with preserved tool use skills. These findings question the role played by function and manipulation knowledge in actual tool use.
