Capuchins (<Emphasis Type="Italic">Cebus apella</Emphasis>) fail to show an asymmetric dominance effect

The asymmetric dominance effect (ADE) occurs when the introduction of a partially dominated decoy option increases the choice share of its dominating alternative. The ADE is a violation of regularity and the constant-ratio rule, which are two derivations of the independence of irrelevant alternatives axiom, a core tenant of rational choice. The ADE is one of the most widely reported human choice phenomena, leading researchers to probe its origins by studying a variety of non-human species. We examined the ADE in brown capuchin monkeys (Cebus apella), a species that displays many other decision biases. In Experiment 1, we used a touchscreen method to elicit choice-based preferences for food rewards in asymmetrically dominated choice sets. In Experiments 2 and 3, we distinguished between different types of judgments and used a free selection task to elicit consumption-based preferences for juice rewards. However, we found no evidence for the ADE through violations of regularity or the constant-ratio rule, despite the similarity of our stimuli to other human and non-human experiments. While these results appear to conflict with existing literature on the ADE in non-human species, we point out methodological differences—notably, the distinction between value-based and perception-based stimuli—that have led to a collection of phenomena that are difficult to understand under a unitary theoretical framework. In particular, we highlight key differences between the human and non-human research and provide a series of steps that researchers could take to better understand the ADE.     

Are parrots poor at motor self-regulation or is the cylinder task poor at measuring it?

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self-control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was challenged when three Corvus species (corvids) were found to parallel great apes despite having much smaller absolute brain sizes. However, new analyses suggest that it is the number of pallial neurons, and not absolute brain size per se, that correlates with levels of motor inhibition. Both studies used the cylinder task, a detour-reaching test where food is presented behind a transparent barrier. We tested four species from the order Psittaciformes (parrots) on this task. Like corvids, many parrots have relatively large brains, high numbers of pallial neurons, and solve challenging cognitive tasks. Nonetheless, parrots performed markedly worse than the Corvus species in the cylinder task and exhibited strong learning effects in performance and response times. Our results suggest either that parrots are poor at controlling their motor impulses, and hence that pallial neuronal numbers do not always correlate with such skills, or that the widely used cylinder task may not be a good measure of motor inhibition.     

Together towards Life,Missional Formation,and Transforming Discipleship

Adoption of Together towards Life as a new mission statement of the World Council of Churches was a moment pregnant with possibility. Will this ground‐breaking document have a transformative impact on individual lives, on community life, on national life, on international life? The answer, to a great extent, will depend on how far it comes to be used as a resource in education and formation. For it to be used in a relevant and effective way, it will need to be considered contextually. A project has been under way to create a pedagogical guidebook to support the deployment of Together towards Life in missional education and formation. This will promote academic rigour, but will also go further to engage the spiritual level and the challenge of discipleship.     

Developmental trajectories to heroin dependence: Theoretical and clinical issues

We have built up a great deal of insight into the early developmental trajectories that lead to heroin use. These cluster under five domains: social disadvantage, parental drug use/psychopathology, childhood abuse and neglect, early onset psychopathology and antisocial behaviors, and a developmental sequence of drug onsets. While not all heroin users have these risk factors, the broad clinical picture shows these early correlates to be the predominant presentation. We discuss each of the early psychosocial correlates of heroin dependence, as well as possible early interventions. Given the chronicity of heroin dependence, interventions to prevent heroin use emerging would reduce the considerable burden of disease associated with the disorder.     

Meta‐Analysis of Counseling Outcomes for Youth With Conduct Disorders

Twenty‐one clinical trials were synthesized using a random‐effects model, which substantiated that counseling generally produces a medium effect in treating conduct disorder in youth at termination (d + = 0.30 to 0.57; k = 28). However, the lasting effects at follow‐up were unclear because few follow‐up studies (k = 13) have been conducted (d + = ?0.53 to 0.58), and only 2 randomized controlled follow‐up studies were located. No effects of moderating variables were evident. Implications for counseling practice and outcome research are addressed.     

Spiritual Distress and Depression in Bereavement: A Meaning-Oriented Contribution

One key focus of a meaning reconstruction model of bereavement concerns spiritual meanings attributed to the death, whether consoling or troubling. Specifically, previous studies in our research program suggest that religiously inclined violent death survivors are at risk for elevated levels of both bereavement distress and complicated spiritual grief, a crisis of faith following loss that refers to the erosion of the mourner’s relationship to God and/or the religious community. However, more research is needed to understand the convergence of depression and spiritual struggle in the context of violent and natural loss. In this study of a diverse sample of 59 American Christians bereaved less than 5 years, we sought to: (1) determine if individuals bereaved by homicide, suicide or fatal accident differed from those bereaved by natural causes in their levels of depression and spiritual coping; (2) investigate the relation between the latter constructs; and (3) ascertain if cause of death mediates the effect of religious coping on depression. We found that: (a) violently bereaved individuals endorsed more negative religious coping, and (b) depression was associated with greater spiritual struggle, particularly a sense of disrupted relationship with God. Contrary to expectations, positive religious coping was unrelated to post-loss depression, and cause of death did not mediate the relationship between spiritual coping and depressive symptomatology. A clinical case study concludes the article, illustrating the interweaving of spiritual and psychological distress in tragic bereavement, and their implications for a meaning-oriented grief therapy.     

Between Luxury and Need: The Idea of Distance in Philosophical Anthropology

Abstract

This paper offers a critical analysis of the use of the idea of distance in philosophical anthropology. Distance is generally presented in works of philosophical anthropology as the ideal coping strategy, which rests in turn on the thesis of the instinct deficiency of the human species. Some of the features of species life, such as its sophisticated use of symbolic forms, come to be seen as necessary parts of this general coping strategy, rather than a merely expressive outlet, incidental to the ultimate goal of life preservation. The paper analyses the arguments used in support of the thesis of instinct deficiency in Hans Blumenberg and considers their implications for the status of symbolic expression in species life. It contrasts the approach this thesis involves with one that proceeds by presenting and arguing from biological evolutionary evidence. The contrast is used to examine the questions: in what sense instinct deficiency is specifically anthropological, and in what precise sense philosophical anthropology is ‘philosophical’.     

Genetic Counseling Assistants: an Integral Piece of the Evolving Genetic Counseling Service Delivery Model

This study explores the potential impact of the genetic counseling assistant (GCA) position on the efficiency of the genetic counseling field, evaluates attitudes regarding expansion of the genetic counseling field to include the GCA, and presents data on GCA endeavors and GCA job tasks as reported by GCAs, certified genetic counselors (CGCs), and program directors (PDs). Data on GCA roles and attitudes toward different aspects of the GCA position were collected via surveys of CGCs who have worked with GCAs, PDs who have and have not had experience with GCAs in their programs, and GCAs. We analyzed responses from 63 individuals: 27 PDs, 22 CGCs, and 14 GCAs. GCAs’ impact on efficiency was calculated via internal analysis of genetic patient volume per genetic counselor within the University of Texas Southwestern (UTSW) patient database prior to, and since the addition of, a GCA to the practice. The response rates for PDs, CGCs, and GCAs were 27 %, 79 %, and 61 %, respectively. Every CGC stated the GCA increased their efficiency. CGCs with a GCA reported a 60 % average increase in patient volume. This figure was congruent with internal data from the UTSW cancer genetics program (58.5 % increase). Appropriate responsibilities for GCAs as reported by CGCs and PDs (>90 %) include: data entry, shipping tests, administrative tasks, research, and ordering supplies. Regarding GCAs delivering test results, there was response variation whether this should be a job duty: 42 % of CGCs agreed to GCAs delivering negative results to patients, compared to 22 % of program directors. Twenty-two percent of PDs expressed concern about the job title “Genetic Counseling Assistant.” Ninety percent of CGCs felt that GCA was a career path to becoming a CGC, compared to 42 % of PDs. Eighty-three percent of GCAs who decided to apply to CGC graduate programs were accepted. We conclude the addition of a GCA to a genetic counseling practice contributes to increased efficiency and is one way to expand the reach of the profession.
