Omission bias in vaccination decisions: Where’s the “omission”? Where’s the “bias”?

Several studies have reported that parents are often reluctant to vaccinate their own or other people’s children, even when the balance of health risks and benefits clearly favors vaccination. This reluctance has been interpreted as a manifestation of “omission bias”, a general tendency to prefer inactive to active options even when inaction leads to worse outcomes or greater risks. The research raises significant public health concerns as well as worries about human decision biases in general. In this paper we argue that existing research on vaccination decisions has not convincingly demonstrated any general reluctance to vaccinate nor has it made the case that such a tendency, if found, would constitute a bias. We identify several conceptual and methodological issues that, we argue, cloud interpretation of earlier studies. In a new questionnaire-based study (Experiment 1) we examined the vaccination decisions of undergraduate students (N=103) and non-student adults (N=192). In both groups a clear majority chose to vaccinate when disease and vaccination risks were balanced. Experiments 2 and 3 identify several problems associated with the measures used in earlier studies, and show how these problems could have led to the misleading appearance of majority anti-vaccination preferences. In our data, vaccination intentions appear to be less a function of generalized preferences for action or inaction than they are of the regret respondents expect to feel if vaccination or non-vaccination were to lead to a poor outcome. Regret-avoiding choices led some respondents to favor vaccination, others to oppose it. In two follow-up studies, few respondents mentioned action or inaction per se in explaining their choices. We conclude that there is no convincing evidence that a generalized “omission bias” plays any important role in vaccination decisions.     

What’s the Harm in Asking About Suicidal Ideation?

Both researchers and oversight committees share concerns about patient safety in the study-related assessment of suicidality. However, concern about assessing suicidal thoughts can be a barrier to the development of empirical evidence that informs research on how to safely conduct these assessments. A question has been raised if asking about suicidal thoughts can result in iatrogenic increases of such thoughts, especially among at-risk samples. The current study repeatedly tested suicidal ideation at 6-month intervals for up to 2-years. Suicidal ideation was measured with the Suicidal Ideation Questionnaire Junior, and administered to adolescents who had previously received inpatient psychiatric care. Change in suicidal ideation was tested using several analytic techniques, each of which pointed to a significant decline in suicidal ideation in the context of repeated assessment. This and previous study outcomes suggest that asking an at-risk population about suicidal ideation is not associated with subsequent increases in suicidal ideation.     

Language switching in the bilingual brain: What’s next?

Recent work using functional neuroimaging with early bilinguals has found little evidence for separate neural systems for each language during picture naming (Hernandez, A. E., Dapretto, M., Mazziotta, J., & Bookheimer, S. (2001). Language switching and language representation in Spanish–English bilinguals: An fMRI study. Neuroimage, 14, 510–520). However, switching between languages in early bilinguals during picture naming shows increased activity in the Dorsolateral Prefrontal Cortex (DLPFC) suggesting the importance of maintaining goal related information in order to bias subsequent response selection (Braver, T. S., Barch, D. M., Kelley, W. M., Buckner, R. L., Cohen, N. J., Miezin, F. M., et al. (2001). Direct comparison of prefrontal cortex regions engaged by working and long-term memory tasks. Neuroimage, 14, 48–59; Cohen, J. D., Braver, T. S., & O’Reilly, R. C. (1996). A computational approach to prefrontal cortex, cognitive control and schizophrenia: Recent developments and current challenges. Philosophical Transactions of the Royal Society of London Series B-Biological Sciences, 351, 1515–1527; O’Reilly, R. C., Braver, T. S., & Cohen, J. D. (1999). A biologically based computational model of working memory. In E. Akira Miyake, E. Priti Shah & et al. (Eds.), Models of working memory: Mechanisms of active maintenance and executive control. (pp. 375–411): New York, NY, USA). The current study set out to test early bilinguals using a picture naming paradigm. Results revealed increased activity in the DLPFC and the superior parietal lobule during language switching compared to naming of pictures in a single language. Increased activity was also observed between early learned first and second languages. The results from single language conditions revealed differences in areas devoted to language processing such as the Superior Temporal Gyrus. However, increased activity in brain areas devoted to memory, somatosensory processing and emotion were also observed. Taken together these results replicate previous studies on language switching. They also extend studies on the neural bases of bilingualism by suggesting that early bilinguals’ representation of the two languages may be mediated by neural systems not typically associated with language. The article ends by considering future directions in understanding the brain bases of language switching and single language processing in bilinguals.     

What’s in a name? Lexical knowledge drives infants’ visual preferences in the absence of referential input

Seventeen-month-old infants were presented with pairs of images, in silence or with the non-directive auditory stimulus ‘look!’. The images had been chosen so that one image depicted an item whose name was known to the infant, and the other image depicted an image whose name was not known to the infant. Infants looked longer at images for which they had names than at images for which they did not have names, despite the absence of any referential input. The experiment controlled for the familiarity of the objects depicted: in each trial, image pairs presented to infants had previously been judged by caregivers to be of roughly equal familiarity. From a theoretical perspective, the results indicate that objects with names are of intrinsic interest to the infant. The possible causal direction for this linkage is discussed and it is concluded that the results are consistent with Whorfian linguistic determinism, although other construals are possible. From a methodological perspective, the results have implications for the use of preferential looking as an index of early word comprehension.

What’s Wrong With Infinite Regresses?

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.     

Children’s spatial thinking: does talk about the spatial world matter?

In this paper we examine the relations between parent spatial language input, children's own production of spatial language, and children's later spatial abilities. Using a longitudinal study design, we coded the use of spatial language (i.e. words describing the spatial features and properties of objects; e.g. big, tall, circle, curvy, edge) from child age 14 to 46 months in a diverse sample of 52 parent-child dyads interacting in their home settings. These same children were given three non-verbal spatial tasks, items from a Spatial Transformation task (Levine et al., 1999), the Block Design subtest from the WPPSI-III (Wechsler, 2002), and items on the Spatial Analogies subtest from Primary Test of Cognitive Skills (Huttenlocher & Levine, 1990) at 54 months of age. We find that parents vary widely in the amount of spatial language they use with their children during everyday interactions. This variability in spatial language input, in turn, predicts the amount of spatial language children produce, controlling for overall parent language input. Furthermore, children who produce more spatial language are more likely to perform better on spatial problem solving tasks at a later age.     

Is transference the ‘total situation’?

This paper examines through the detailed explication of analytic material the author's experience of a psychoanalytic and a Jungian way of understanding the interactions between him and his patient. This comparative approach considers where the differences lie with respect to timing and content of interpretations and where the differences are essentially tactical rather than theoretical.     

Autism,early narcissistic injury and self‐organization: a role for the image of the mother’s eyes?

Holland elucidated the new paradigm of self-organization in complex adaptive systems. This paradigm holds for all living systems, including the personality. In conjunction with the theory of archetypes, self-organization suggests two radical hypotheses, one about early development, the other about the origins of autism. Autism is associated with several medical conditions, with genetic markers, and with infant visual deprivation. However none of these factors is either necessary or sufficient to cause autism. It is hypothesized that each of these factors increases the likelihood of a primary psychological deficit: failure to acquire, or retain, the image of the mother's eyes. This hypothesis was initially derived from analytic work with patients who have early narcissistic injury and with patients who have mild autistic traits. Both diagnoses may arise from the same initial disturbance: Symington argued that autism is an extreme form of infantile narcissism. Indirect evidence for the image-of-the-eyes hypotheses comes from the evolution of primates, from infant-mother observations, from observations of infant vision, and from experiments on vision in other vertebrates. Byrd recently confirmed that the incidence of autism is increasing dramatically. The image-of-the-eyes hypotheses suggest that this increase may be linked to increased use of non-maternal childcare for young infants.     

Extracurricular activities in young applicants’ résumés: What are the motives behind their involvement?

Applicants use résumés to demonstrate their knowledge, skills, abilities, and other personal characteristics (KSAOs) to recruiters, through education and job‐related or non‐job‐related experiences. But research suggests that the situation for young applicants is especially competitive, since they increasingly enter the labour market with similar educational credentials and limited job‐related experience. They may thus use non‐job‐related experiences, such as participation in extracurricular activities (ECAs) during their studies, to demonstrate KSAOs to recruiters, but also to add distinction and value to their credentials. ECAs may therefore become more important in the selection of young applicants. Yet few studies have undertaken a comprehensive and systematic analysis of the relationships students have with these activities. The purpose of this study was to investigate to what extent students’ involvement in ECAs is due to internal (e.g., passion) or external (e.g., résumé‐building) motives, and what factors influence these motives. Results from a study with 197 students suggest that students engage in ECAs mainly out of internal motives. But external motives are stronger for activities started closer to entering the labour market, for students active in associative or volunteering activities (as compared to sports or artistic activities), and for students holding leadership positions in their activities. Our results suggest that labour market pressure may be a key component of applicants’ involvement in ECAs. Also, organizations and recruiters may want to consider that students tend not to engage in ECAs purely out of internal motives, but also to add value to their credentials and match employers’ expectations.     

Internal objects' or ‘chimerical monsters’?: the demonic ‘third forms’ of the internal world

The concept of 'object' whether internal or external, is a hold-over from the Enlightenment and from the positivistic certainty of nineteenth- and early twentieth-century science, Its use in current psychoanalytic theory and practice is now obsolete because of the contributions of post-modernism and their emphasis on subjectivity and relativity. In plate of the word 'object', the author favors a return to pre-Enlightenment psychology in order to address the presence and clinical manifestation of what the term 'object' screened, i.e., demons, monsters, chimerae, ghosts, spirits, etc. In terms of external 'objects', he favors such terms as 'persons' or 'subjects', which also reflects an adjustment to the post-modem emphasis on the ineffability of the Other.     

The Trinity as our Ecclesial Program? Assessing Miroslav Volf’s Trinitarian Theology of the Church

This article argues that while there are missteps in Mirolsav Volf’s proposal of a trinitarian theology of the church, his impulse to coordinate these doctrines is to be commended and built upon. Specifically it argues that Volf falters by moving from intra‐trinitarian relations to an ethical‐structural orientation for the church too quickly, but that alternative models of coordination can succeed to the extent that they follow a proper progression of dogmatic grounding from God’s triune processions through the triune missions to a constitution of the church’s being, then to an orientation of the church’s mission and, finally, to a determination of the church’s organization and ethics.
