Children's intuitive sense of number develops independently of their perception of area,density, length,and time

Young children can quickly and intuitively represent the number of objects in a visual scene through the Approximate Number System (ANS). The precision of the ANS – indexed as the most difficult ratio of two numbers that children can reliably discriminate – is well known to improve with development: whereas infants require relatively large ratios to discriminate number, children can discriminate finer and finer changes in number between toddlerhood and early adulthood. Which factors drive the developmental improvements in ANS precision? Here, we investigate the influence of four non‐numeric dimensions – area, density, line length, and time – on ANS development, exploring the degree to which the ANS develops independently from these other dimensions, from inhibitory control, and from domain‐general factors such as attention and working memory that are shared between these tasks. A sample of 185 children between the ages of 2 and 12 years completed five discrimination tasks: approximate number, area, density, length, and time. We report three main findings. First, logistic growth models applied to both accuracy and Weber fractions (w; an index of ANS precision) across age reveal distinct developmental trajectories across the five dimensions: while area and length develop by adolescence, time and density do not develop fully until early adulthood, with ANS precision developing at an intermediate rate. Second, we find that ANS precision develops independently of the other four dimensions, which in turn develop independently of the ANS. Third, we find that ANS precision also develops independently from individual differences in inhibitory control (indexed as the difference in accuracy and w between Congruent and Incongruent ANS trials). Together, these results are the first to provide evidence for domain‐specific improvements in ANS precision, and place children's maturing perception of number, space, and time into a broader developmental context.     

Body Shame and Disordered Eating in Adolescents

This study aimed to examine the predictive utility of body shame on eating behaviors in adolescents, while controlling for age, sex and body mass index (BMI). Participants were 400 Croatian adolescent girls and boys who completed self-report questionnaires assessing body shame and eating behaviors. Results showed that the mean eating behaviors score and the mean body shame score were significantly higher in females compared to males. Body shame explained statistically significant amount of eating behaviors variance after controlling for age, sex and BMI. Participants’ age and BMI did not play a role as significant predictors of eating behaviors. Implications for future research, including the importance of prospective longitudinal designs, are discussed.     

Information Needs and Behavior of Catholic Priests in Croatia

This article presents a segment of the results gathered in a doctoral study that investigated information needs and behavior of Catholic priests in Croatia. The study focused on parish priests in particular and their information needs and behavior in the liturgy and care-giving role. The research was conducted with the help of quantitative and qualitative methodology. Print questionnaires were filled out by 327 respondents, while in the follow-up interviews 20 respondents took part. Research results show that respondents, in the care-giving role and liturgy, require information about theology, general culture, psychology, and pedagogy. More than half of respondents find information for liturgy on religious websites and in their personal parish libraries. However, in their care-giving role they seek information most often from their parishers, members in parish pastoral and economic boards, and from colleagues at their regular meetings organized by the (arch)diocese. Both in liturgy and care-giving role, respondents use religious publications to a much larger degree than secular books, magazines, or newspapers. The respondents explained that in liturgy they consult colleagues and parishers in order to exchange advices and ideas, while in the care-giving role some respondents also prefer to seek an advice from an expert in specific field. The results of this study can help Catholic Church and theological faculties when preparing the information literacy courses for future parish priests.     

A Developmental Vocabulary Assessment for Parents (DVAP): Validating Parental Report of Vocabulary Size in 2- to 7-Year-Old Children

Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to 37 months of age. Here, we test the validity of a new assessment to fill this gap: the Developmental Vocabulary Assessment for Parents (DVAP). In 4 experiments, we assess the reliability of this measure and its concurrent and predictive validity in samples of 2- to 7-year-old children. We found that the DVAP provides a rapid, cost-effective alternative to experimenter-administered vocabulary tests for children.     

Authorship in a small medical journal: A study of contributorship statements by corresponding authors

The authorship criteria of the International Committee of Medical Journal Editors (ICMJE) are widely accepted in biomedical journals, but many studies in large and prestigious journals show that a considerable proportion of authors do not fulfill these criteria. We investigated authorship contributions in a small medical journal outside the scientific mainstream, to see if poor adherence to authorship criteria is common in biomedical journals. We analyzed statements on research contribution, as checked by the corresponding author, for individual authors of 114 research articles, representing 475 authors, submitted to the Croatian Medical Journal (CMJ) from 1999 to 2000. Only 40% of authors fulfilled the ICMJE authorship criteria. The authors listed first on the by-line were more likely to fulfill the authorship criteria than all other authors on the by-line. The percentage of authors fulfilling the ICMJE criteria of authorship decreased with the increase in the number of authors listed on the by-line. These results indicate that poor adherence to ICMJE authorship criteria is poor across biomedical journals, regardless of the size of the scientific community. Authorship and contributorship in biomedical journals, as well as editorial ethical responsibilities towards authorship criteria need critical redefinition and education of both editors and authors.     

The relationship between apparent motion and object files

Object files (OFs) play an important role in theories of mid-level vision. On some influential views, OFs operate and persist only via spatiotemporal continuity. One open question concerns what occurs when direct spatiotemporal continuity is absent: Do OFs move in accordance with any motion correspondence ultimately resolved? Specifically, do OFs accord with apparent motion (AM) correspondences, which arise despite a lack of continuous spatiotemporal stimulation? In Experiment 1, subjects were presented with an AM display consisting of two circles that, across two frames, were seen as moving between two noncontiguous locations. The two objects were primed with two symbols and were then moved in a single step; a third symbol appeared, and could either match the symbol from the closer or the further object. We found a robust object specific preview benefit (OSPB) for the shorter path, in other words, the path along which AM was perceived. In order to control for the possibility that priming occurs at any nearby object, in Experiment 2, the original two objects never disappeared, but two new objects appeared in the would-be AM locations. No AM was perceived, and no OSPB obtained. In the third experiment the OSPB effect persisted even when motion along the shorter path included an unlikely featural transformation (circles turning into squares). In Experiment 4, which was nearly identical to Experiment 2, no OSPB obtained despite unique featural matches between the initial and new objects, seemingly because no AM was perceived. In Experiment 5, we failed to find an effect of featural priming, even when distance between the objects was equated. Finally, we extended the OSPB effect to two additional kinds of AM—line motion (Experiment 6) and phi motion (Experiment 7), supplying strong evidence that AM correspondences and OF correspondences are controlled by the same basic rules.     

Medical Students’ Decisions About Authorship in Disputable Situations: Intervention Study

In medicine, professional behavior and ethics are often rule-based. We assessed whether instruction on formal criteria of authorship affected the decision of students about authorship dilemmas and whether they perceive authorship as a conventional or moral concept. A prospective non-randomized intervention study involved 203s year medical students who did (n = 107) or did not (n = 96) received a lecture on International Committee of Medical Journal editors (ICMJE) authorship criteria. Both groups had to read 3 vignettes and answer 4 questions related to the distinction between conventional and moral domains. Written justification of student’ choices whether the authorship in a vignette was right or wrong was rated by 4 independent raters as based on justice or a rule. Formal instruction had no effect on students’ decisions on authorship in the vignettes (44, 34 and 39% ICMJE-consistent answers for 3 vignettes, respectively, by students receiving instruction vs. 38, 42 and 30% for those without instruction; P > 0.161 for all vignettes). For all dilemmas, more students decided contrary to ICMJE criteria and considered their decisions to be a matter of obligation and not a choice and to be general across situations and sciences. They were willing to change their decision if a rule was different only for peer situations but not for mentor–mentee situations. The number of students who used rule-based justification of their ICMJE criteria-consistent decisions was significantly higher in the instructed than in the uninstructed group. Instruction about formal authorship criteria had no effect on student’s decisions about authorship dilemmas and their decisions were related to the moral rather than a conventional domain. Teaching about authorship and other professionalism and integrity issues may benefit from interventions that bring intuitive processes into awareness instead of those fostering rule-based reasoning.     

Spiritual Well-Being, Cortisol, and Suicidality in Croatian War Veterans Suffering from PTSD

We present our preliminary results of work that aims to observe the relationship between the cortisol level, the level of spiritual well-being, and suicidal tendencies in Croatian war veterans suffering from PTSD. The survey was conducted on 17 PTSD veterans who completed the Spiritual Well-Being Scale and the Beck Hopelessness Scale. The plasma cortisol level was obtained by venepuction at 8.00, 12.00, 13.00, 16.00, and 22.00 h. Results showed that veterans with higher spiritual well-being scores had lower cortisol levels, and evening cortisol levels showed significant correlation with suicidal risk. The results of the present study could be a stimulus for further investigation into spiritually based interventions, exploring their impact both on mental status and physical health.
