Major memory for microblogs

Online social networking is vastly popular and permits its members to post their thoughts as microblogs, an opportunity that people exploit, on Facebook alone, over 30 million times an hour. Such trivial ephemera, one might think, should vanish quickly from memory; conversely, they may comprise the sort of information that our memories are tuned to recognize, if that which we readily generate, we also readily store. In the first two experiments, participants’ memory for Facebook posts was found to be strikingly stronger than their memory for human faces or sentences from books—a magnitude comparable to the difference in memory strength between amnesics and healthy controls. The second experiment suggested that this difference is not due to Facebook posts spontaneously generating social elaboration, because memory for posts is enhanced as much by adding social elaboration as is memory for book sentences. Our final experiment, using headlines, sentences, and reader comments from articles, suggested that the remarkable memory for microblogs is also not due to their completeness or simply their topic, but may be a more general phenomenon of their being the largely spontaneous and natural emanations of the human mind.     

Magnitude and determinants of behavioral risk reduction: Longitudinal analysis of a cohort at risk for AIDS

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction.     

Development of decisional balance and self-efficacy measures for adolescent sedentary behaviors

Writing about traumatic events can produce health benefits, yet emotionally non-expressive or cognitively avoidant individuals may be unwilling or unable to express their emotions. This study examined non-expression, cognitive avoidance, response to writing, and subsequent health. As part of a larger study, participants ( N = 71) with asthma or rheumatoid arthritis (RA) wrote about traumatic experiences for 20 min on three consecutive days. Alexithymia, denial, behavioral disengagement, mental disengagement, focus on/venting of emotions, avoidant thoughts, and health status were assessed at baseline, health status again 4 months after writing. Essays were coded for how personal and how emotional they were, and for narrative structure. Non-expression and cognitive avoidance were neither related to how personal or emotional essays were, nor to affective response to writing. High levels of denial or avoidant thoughts predicted less narrative structure. Avoidant thinking marginally predicted health improvements in RA patients. Results suggest that non-expression and cognitive avoidance do not interfere with writing in terms of emotional engagement, but may influence narrative use.     

Relationship between the number of life events and memory capacity in children

Stressful life events can result into declined memory performance at later age. One hypothesis suggests that stress affects the hippocampus, a brain area important for memory functioning. This study explored a potential relationship between the number of negative stressful life events and hippocampus-dependent declarative but not hippocampus-independent procedural memory performance in a community sample of 255 children, aged 6–12 years. The findings revealed that negative stressful life events were negatively related to verbal declarative memory, but not to nonverbal declarative and procedural memory. The memory impairments could not be accounted for by attention and sleep disturbances, and parenting characteristics as perceived by the child did not influence the vulnerability for the stress-related memory impairments. These findings provide further insight into the deleterious effects of negative stressful life events on learning in school-aged children.     

Women Experiencing Psychological Abuse: Are They a Homogenous Group?

Dichotomizing women as “abused” versus “not abused” assumes that any psychological maltreatment results in similar outcomes. A national sample of women in conflictual relationships completed an online survey. Women with no incidence (N = 33), the lowest quartile (N = 86), and the top quartile (N = 81) of psychological maltreatment demonstrated significant differences in reactions to the maltreatment, mental health indicators, personality variables, perceived harm, problematic relationship schemas, and response styles. Women with no psychological abuse and women in the lowest quartile produced similar scores that were typically distinct from the top-quartile women. Effective treatment of women with lower amounts of psychological abuse might not require a unique intervention likely necessary for women experiencing much psychological abuse.     

Testing Posttraumatic Stress as a Mediator of Childhood Trauma and Adult Intimate Partner Violence Victimization

This study examined whether potential posttraumatic stress disorder (PTSD) mediated the relationships between different forms of childhood trauma (sexual abuse, physical abuse, violence between caregivers) and intimate partner violence (IPV) victimization (psychological, physical, sexual). Participants were 1,150 female nurses and nursing personnel. Path analytic findings revealed potential PTSD partially mediated the relationships between childhood sexual abuse and psychological IPV and childhood sexual abuse and sexual IPV. Potential PTSD did not mediate the relationship between other types of childhood trauma and IPV. This study adds to the literature indicating PTSD as a risk factor for revictimization in the form of adult IPV among women. Screening for and treatment of PTSD among female child sexual abuse survivors could prevent future IPV victimization.     

Gender Differences in Reporting Psychological Abuse in a National Sample

Understanding the nature and impact of psychological abuse for males and females is crucial because it might be the precursor of other forms of violence. This study examines reported gender differences in psychologically abusive acts using a national sample of U.S. citizens. The data were collected anonymously from an online administration of the Measure of Psychological Abuse (MPAB). Other measures were included to assess outcomes that might occur due to psychological abuse. Results indicate that there are more similarities than differences in the gender reports of psychological abuse. Compared to males' reports, differences include female reports of certain behaviors leading to more negative emotional and behavioral impact and more negative outcomes due to being in a psychologically abusive relationship.     

Understanding Patients' Reactions to Services: The Role of Personal Service Values in Heart Patient Satisfaction and Wellness

This study proposed an individual-difference perspective on heart patients' customer-service satisfaction. We hypothesized that heart patients' satisfaction with service is positively related to wellness and that instrumental care, expressive care, and communication effectiveness are positively related to satisfaction and wellness. We also hypothesized that patients' values for services would moderate the relationship between service provision and outcomes. A survey of 217 heart patients provided support for these hypotheses. Of particular interest were findings that: (a) the service provision-service outcomes relationship was moderated by service values for some patient groups but not for others; and (b) the service provision-outcomes relationship differed across patient subgroups. We discuss the implications for patient satisfaction research and for planning individualized treatment strategies.     

Measurement of newcomer socialization: Construct validation of a multidimensional scale

A construct validation approach was taken to develop a primary measure of newcomer socialization that addresses shortcomings with a prior scale (Chao, Kelly, Wolf, Klein, & Gardner, 1994). Three separate groups of subject matter experts reviewed items to ensure the content validity of the Newcomer Socialization Questionnaire (NSQ). Studies 1 and 2 examined the NSQ’s psychometric properties using employed students and organizational newcomers as participants, respectively. Results illustrate scale reliability, factor structure, convergent and discriminant validity, and correlations with criterion variables. The NSQ measures three dimensions or domains of newcomer socialization: the organization, the group and the job/task. In addition, both factual knowledge and knowledge of expected role behaviors are assessed within each domain. Thus, the NSQ provides a useful measurement tool for researchers and practitioners interested in examining direct outcomes of being socialized.
