Aging and the perception of depth and 3-D shape from motion parallax

The ability of younger and older observers to perceive 3-D shape and depth from motion parallax was investigated. In Experiment 1, the observers discriminated among differently curved 3-dimensional (3-D) surfaces in the presence of noise. In Experiment 2, the surfaces' shape was held constant and the amount of front-to-back depth was varied; the observers estimated the amount of depth they perceived. The effects of age were strongly task dependent. The younger observers' performance in Experiment 1 was almost 60% higher than that of the older observers. In contrast, no age effect was obtained in Experiment 2. Older observers can effectively perceive variations in depth from patterns of motion parallax, but their ability to discriminate 3-D shape is significantly compromised.     

Were the “Pioneer” Clinical Ethics Consultants “Outsiders”? For Them,Was “Critical Distance” That Critical?

“Clinical ethics consultants” have been practicing in the United States for about 50 years. Most of the earliest consultants—the “pioneers”—were “outsiders” when they first appeared at patients' bedsides and in the clinic. However, if they were outsiders initially, they acclimated to the clinical setting and became “insiders” very quickly. Moreover, there was some tension between traditional academics and those doing applied ethics about whether there was sufficient “critical distance” for appropriate reflection about the complex medical ethics dilemmas of the day if one were involved in the decision making. Again, the pioneers deflected concerns by identifying and instituting safeguards to assure professional objectivity in clinical ethics consultation services. One might suggest that in moving inside and establishing normative practices, the pioneer clinical ethics consultants anticipated adoption of their routines and professionalization of the field.     

Effects of a Workplace Intervention on Parent–Child Relationships

This study tested whether effects of a workplace intervention, aimed at promoting employees’ schedule control and supervisor support for personal and family life, had implications for parent–adolescent relationships; we also tested whether parent–child relationships differed as a function of how many intervention program sessions participants attended. Data came from a group randomized trial of a workplace intervention, delivered in the information technology division of a Fortune 500 company. Analyses focused on 125 parent–adolescent dyads that completed baseline and 12-month follow-up home interviews. Results revealed no main effects of the intervention, but children of employees who attended 75 % or more program sessions reported more time with their parent and more parent education involvement compared to adolescents whose parents attended <75 % of sessions, and they tended to report more time with parent and more parental solicitation of information about their experiences compared to adolescents whose parents were randomly assigned to the usual practice condition.     

Cancer Worry,Perceived Risk and Cancer Screening in First-Degree Relatives of Patients with Familial Gastric Cancer

Currently, there is a lack of evidence evaluating the psychological impact of cancer-related risk perception and worry in individuals at high risk for gastric cancer. We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants’ high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.     

Posttraumatic Growth and Sexual Violence: A Literature Review

Posttraumatic growth (PTG) is the positive psychological growth that a person might experience after enduring a traumatic event. PTG is a relatively new area of research identified by researchers because it represents a shift in thinking. Rather than focusing on the negative consequences of trauma, it explores the potential for positive outcomes associated with trauma. Although PTG is well documented across different types of traumas, it is unclear how this kind of growth stems from sexual violence, specifically. This review provides an overview of the literature concerning PTG that is associated with sexual violence. Results across the literature indicate that sexual violence is consistently associated with PTG. However, given the inconsistency in research designs, assessment, and operational definitions used to study PTG, many researchers suggest that it might be difficult to determine how and when PTG occurs. This study provides a literature review of the research on PTG in the aftermath of sexual violence. Important implications for future directions and trauma-based therapy are discussed and include the identification of relevant predictors, the importance of context, and how service providers might benefit from a better understanding of PTG.     

Enhancing Parenting Skills Among Nonresident African American Fathers as a Strategy for Preventing Youth Risky Behaviors

This study evaluated the effectiveness of a theoretically based, culturally specific family intervention designed to prevent youth risky behaviors by influencing the parenting attitudes and behaviors of nonresident African American fathers and the parent–child interactions, intentions to avoid violence, and aggressive behaviors of their preadolescent sons. A sample of 158 intervention and 129 comparison group families participated. ANCOVA results indicated that the intervention was promising for enhancing parental monitoring, communication about sex, intentions to communicate, race-related socialization practices, and parenting skills satisfaction among fathers. The intervention was also beneficial for sons who reported more monitoring by their fathers, improved communication about sex, and increased intentions to avoid violence. The intervention was not effective in reducing aggressive behaviors among sons. Findings are discussed from a family support perspective, including the need to involve nonresident African American fathers in youth risky behavior prevention efforts.     

Psychologists and the Ethical Use of Enhanced Interrogation Techniques to Save Lives

Arrigo, DeBatto, Rockwood, and Mawe (2015) take issue with a number of arguments in our previous article (O’Donohue et al., 2014). We respond in four major ways: (a) pointing out that they never really take on, let alone refute, the key argument in our article—that utilitarian, deontic, and virtue ethical theories are not only consistent with the use of enhanced interrogation and torture in the ticking time bomb scenario but these prescribe it; (b) there are numerous other exegetical problems in their article; (c) they make unsubstantiated claims about the ineffectiveness of EITSLs techniques that we argue are much too strong; and (d) they conflate the ethical with the legal and but even in doing so miss many important issues regarding the legality of EITSLs in the war on terrorism.
