Wisdom and aging: irrational preferences in college students but not older adults

A decision-maker is "irregular" if she would choose B from [A, B, C] but not from [A, B] (for example, preferring vanilla ice cream in a choice between vanilla and chocolate, but chocolate in a choice among vanilla, chocolate and strawberry). Similarly to previous studies we observed irregular choices by college students faced with hypothetical discount cards for supermarkets. However, older adults showed no such tendency. The same pattern was observed in three separate studies. We interpret the results in terms of a choice strategy by older adults that protects them from excessive spending.     

Promotion of social change: a conceptual framework

This paper argues for the need to advance promotion efforts and proposes a conceptual framework for promotion of social change. A brief review is presented of traditional frameworks for the prevention of mental and social disorders and the promotion of wellness and social competencies, with attention to the ways in which promotion of social change extends and departs from these frameworks. In a framework for promoting social change, we advocate for promoting dynamic processes within systems, rather than outcomes within individuals. Systems are viewed as flexible and capable of facilitating multiple adaptive pathways for individuals and groups. Promoting social change also involves careful attention to critical analysis, values, language, and contextual processes. Examples are discussed throughout to illustrate how these principles have been used in the past and can be implemented in future efforts to promote social change.     

Disappearance elicited by contrast decrements

The observation that physically present visual stimuli can sometimes disappear from consciousness has intrigued vision scientists for centuries. Two situations are known to cause such disappearance: stationary peripheral images and images (centrally or peripherally viewed) masked by abrupt contrast increments of stimuli in adjacent retinal areas. Both of these situations require near-image stabilization on the retina. Here, we describe a third way to remove stimuli from conscious awareness. It involves contrast decrements (CDs) of nearly stabilized images in the periphery. Unlike the Troxler effect, with sufficient CD, complete disappearance can be achieved almost instantaneously without significant adaptation periods. Unlike traditional masking effects, CD disappearance does not result in an after-image at or near the locus of stimulation. We report the results of four experiments in which some of the characteristics of this newly discovered phenomenon were examined. The results indicate that CDs produced by changes in the luminance of the target (see Experiment 2) or by changes in background luminance (see Experiment 3) result in an immediate loss of sensitivity to stimuli that would take much longer to fade with Troxler-like adaptation (see Experiment 1). However, the duration of such loss of sensitivity (approximately 2 sec) is comparable for the two paradigms. The frequency of disappearance increased with greater contour eccentricity, but disappearance duration remained fairly constant.     

Tactical differences in coping with rejection sensitivity: the role of prevention pride

Prevention pride reflects a person's subjective history of success in preventing negative outcomes, leading to a strategic avoidance of errors of commission (e.g., explicit mistakes) in new situations. Two studies examined the impact of prevention pride on the strategies that highly rejection sensitive (HRS) people use to cope with the anxiety of anticipated rejection and the negative feelings elicited by perceived rejection. It was hypothesized that prevention pride orientation would lead HRS people toward covert and passive rather than overt and active forms of negative coping. Results indicated that HRS individuals who were also high in prevention pride reported increased use of self-silencing, presumably to prevent rejection. When rejection was perceived, however, they expressed hostility passively, by reducing positive behavior (e.g., withdrawing love and support) while inhibiting direct, active acts of hostility (e.g., yelling).     

Physician-assisted suicide, euthanasia, and Christian bioethics: moral controversy in Germany.

Discussions in Germany regarding appropriate end-of-life decision-making have been heavily influenced by the liberalization of access to physician-assisted suicide and voluntary active euthanasia in the Netherlands and Belgium. These discussions disclose conflicting moral views regarding the propriety of physician-assisted suicide and euthanasia, threatening conflicts within not only the medical profession, but also the mainline churches in Germany, whose membership now entertains views regarding end-of-life decision-making at odds with traditional Christian doctrine. On the surface, there appears to be a broad consensus supporting the hospice movement and condemning physician-assisted suicide and euthanasia. The German Supreme Court has held that treatment decisions should, in absence of known patients' wishes, be made in light of commonly shared values, unless these violate the principle of "in dubio pro vita". The Roman Catholic church and the Evangelical Lutheran church in Germany have developed an advance directive for treatment choices at the end of life, while condemning physician-assisted suicide and euthanasia. This stance is in tension with the strong emerging support for physician-assisted suicide and euthanasia, a development that promises to open up foundational disagreements within mainline German Christianity regarding the appropriate approach to intentionally terminating human life.     

Personality characteristics of ADHD adults assessed with the Millon Clinical Multiaxial Inventory-II: evidence of four distinct subtypes

This study compared the personality characteristics of 104 adults diagnosed with attention deficit hyperactivity disorder (ADHD). Personality features were assessed with the MCMI-II (Millon, 1987). Participants were divided into 4 groups based on the presence of persisting oppositional defiant disorder (ODD) or other comorbid diagnoses (ADHD only, ADHD-comorbid, ADHD-ODD, ADHD-ODD-comorbid). Significant differences between these groups were present for 9 of the 13 MCMI-II personality scales, resulting in 4 modal personality styles. ADHD-only adults evidenced mild histrionic traits, whereas the ADHD-comorbid group was more often avoidant and dependent in personality style. ADHD-ODD adults showed histrionic, narcissistic, aggressive-sadistic, and negativistic traits whereas the ADHD-ODD-comorbid group had a combination of avoidant, narcissistic, antisocial, aggressive-sadistic, negativistic, and self-defeating personality features. Implications for treatment are discussed.
