Duties to the Distant: Aid, Assistance, and Intervention in the Developing World

In his classic article, Famine, Affluence, and Morality (Philosophy and Public Affairs 1 (1972), pp. 229–243), Peter Singer claimed that affluent people in the developed world are morally obligated to transfer large amounts of resources to poor people in the developing world. For present purposes I will not call Singers argument into question. While people can reasonably disagree about exactly how demanding morality is with respect to duties to the desperate, there is little question in my mind that it is much more demanding than common sense morality or our everyday behavior suggests. Even someone who disagrees with this might still find some interest in seeing what a demanding morality would imply for well-off residents of the rich countries of the world. I proceed in the following way. First, I survey humanitarian aid, development assistance, and intervention to protect human rights as ways of discharging duties to the desperate. I claim that we should be more cautious about such policies than is often thought. I go on to suggest two principles that should guide our actions, based on an appreciation of our roles, relationships, and the social and political context in which we find ourselves.     

Biases and fallacies, memories and predictions: comment on Roy, Christenfeld, and McKenzie (2005)

Comparative theory testing is a useful method for assessing the value of a new theoretical account such as the memory bias account of optimistic time predictions. However, such comparisons can be misleading when they do not carefully consider the domain limitations of the respective theories. M. M. Roy, N. J. S. Christenfeld, and C. R. M. McKenzie have contrasted the memory bias and planning fallacy accounts in their ability to explain the prevalence and degree of optimistic bias in time predictions. However, the authors argue that many of the points of distinction they draw are actually reflections of the domain limitations of the 2 theories. The authors clarify the definition and scope of the planning fallacy account and show how the apparent contradictions diminish or disappear.     

Trial order and retention interval in human predictive judgment

The influences of order of trial type and retention interval on human predictive judgments were assessed for a cue that was reinforced on half of its training presentations. Subjects observed 10 cue-outcome presentations (i.e., reinforced trials) and 10 cue-alone presentations (i.e., nonreinforced trials) in one of three different orders: all nonreinforced trials followed by all reinforced trials(latent inhibition), reinforced and nonreinforced trials interspersed (partial reinforcement), or al lreinforced trials followed by all nonreinforced trials (extinction). Ratings were based mainly on the most recent event type (i.e., a recency effect) when the test occurred immediately after training but were based mainly on initial event types (i.e., a primacy effect) when the test occurred after a 48-h delay. The subjects tested both immediately and with a long retention interval did not exhibit this shift to primacy (i.e., the recency effect persisted). These results demonstrate noncatastrophic forgetting and the flexible use of trial order information in predictive judgments.     

The emergence of homegrown stereotypes

Homegrown stereotypes are generalizations that groups develop about their own typical characteristics. They are a distinct class of in-group stereotypes in the contexts and processes that give rise to them, as well as in their consequences for individual group members. The authors develop the concept of homegrown stereotypes and locate the origins of these stereotypes in self-presentation processes. They discuss the accuracy of these stereotypes and consider their similarities to and differences from a number of related phenomena. An examination of homegrown stereotypes highlights the importance of taking into account the impact of in-group, as well as intergroup, dynamics on the production of stereotypes.     

Aspiration-Based and Reciprocity-Based Rules in Learning Dynamics for Symmetric Normal-Form Games

Psychologically based rules are important in human behavior and have the potential of explaining equilibrium selection and separatrix crossings to a payoff dominant equilibrium in coordination games. We show how a rule learning theory can easily accommodate behavioral rules such as aspiration-based experimentation and reciprocity-based cooperation and how to test for the significance of additional rules. We confront this enhanced rule learning model with experimental data on games with multiple equilibria and separatrix-crossing behavior. Maximum likelihood results do not support aspiration-based experimentation or anticipated reciprocity as significant explanatory factors, but do support a small propensity for non-aspiration-based experimentation by random belief and non-reciprocity-based cooperation.     

Substance or style? An investigation of the NEO-PI-R validity scales

The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) has been criticized for the absence of validity scales designed to detect response distortion. Recently, validity scales were developed from the items of the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and several studies have used a variety of methods to test their use. However, it is controversial whether these scales are measuring something that is substantive (such as psychopathology or its absence) or stylistic (which might be effortful distortion or less conscious processes such as lack of insight). In this study, we used a multimethod-multitrait approach to examine the validity of these scales in a clinical sample of 668 participants diagnosed with personality disorders or major depression. Using various indicators of both stylistic and substantive variance, confirmatory factor analyses (CFA) suggested that these validity scales measure something that may be conceptually distinct from, yet highly related to, substantive variance in responding.     

Aftereffects of the surprising presentation and omission of appetitive reinforcers on key-pecking performance in pigeons

The reinforcement-omission effect (ROE), also known as frustration effect, refers to greater response strength immediately after nonreinforcement (N) than reinforcement (R). The ROE was traditionally interpreted as transient invigoration after N induced by primary frustration. Pigeons demonstrate similar ROEs whether outcomes are surprising (partial R) or expected (discrimination training) in runway (Experiment 1) and Skinner box situations (Experiments 2-3). Variations in the interval between N and the opportunity to respond indicate that the ROE results from an aftereffect of food consumption (Experiment 4). Increasing reinforcer magnitude increased the after-R effect, without modifying the after-N function (Experiment 5). These results are reviewed in the context of comparative research on spaced-trial successive negative contrast and related phenomena that have failed to appear in experiments involving nonmammalian vertebrates.     

Patterns of impaired verbal,spatial, and object working memory after thalamic lesions

Working memory processes in six individuals with isolated thalamic lesions were assessed. Participants were given a verbal, spatial, and object n-back task, each at three levels of task load (1-back, 2-back, and 3-back). Relative to a control group, the patients were impaired on the verbal and spatial n-back tasks, and possibly on the object n-back task as well. None of the patients showed impaired short-term memory as measured by digit span. Group differences on trials measuring matching, sequencing, and inhibitory abilities were consistent with other reports suggesting that thalamic lesions may impair the operation of executive processes.     

Challenges of Being Simultaneously Gay or Lesbian and Spiritual and/or Religious: A Narrative Perspective

The purpose of this article is to describe the struggle that gays and lesbians face as they incorporate their sexual orientation and identity within the context of an existing religious or spiritual identity. An overview of the religious and spiritual context that makes individuals unique will be followed by how the narrative perspective can help individuals who identify themselves as gay or lesbian with their struggle for identity. Finally, new narrative directions will be suggested for marriage and family therapists and their work with gays and lesbians who are confronted with these issues.     

Alcoholism and the family in peru: The impact of an alcoholic on teenagers' perceptions of the family

Abstract

We studied Peruvian high school students' perceptions of their family environment when a member of their household had a significant problem with alcohol using specialized forms of both the Family Environment Scale (FES) and the Michigan Alcohol Screening Test (SMAST). Of our sample of 218 high school students in Lima, Peru, 91.7% lived in a household in which a member had a significant problem with alcohol as defined by the family form of the SMAST. Also, when the alcoholic individual was a member of the nuclear family, the high school students perceived their families as less cohesive, less well organized, and with a lesser ability to express themselves. These family perceptions are similar to those found in American high school students who live with an alcoholic family member. Possible epidemiologic and family implications of these findings are discussed.
