ABSTRACT

It has been suggested that increased status that comes from being an award winner can generate enduring advantages that compound over one's career via the Matthew Effect. However, research in this area has yielded conflicting results and has been unable to isolate the unique effect of status on career outcomes from the positive endogenous characteristics of award winners. In the current research, we attempt to address previous research limitations and examine if winning an award is associated with career outcomes (i.e., opportunities and productivity) irrespective of individual productivity levels prior to receiving an award. We examined our research questions using observational data of National Hockey League (NHL) league championship winners and non-winners (N = 427). By using a team award and several different analytic approaches we were able to examine the unique effects of affiliation-based external status, generated from an award win, on career outcomes. Our results generally show support for the Matthew Effect and suggest that affiliation-based external status, achieved by an award win, provides access to increased opportunities, which ultimately results in more productivity. We discuss the importance of incorporating opportunity and investigating its role in the cumulative advantage process and implications of the results.

ABSTRACT

Children's needle-related distress is strongly related to parental verbal behaviors. Yet, empirical data supporting theorized contributors to parent behaviors in this context remain limited. This is the first study to collectively measure biological (heart rate variability; HRV), psychological (catastrophizing, anxiety), and social (child behaviors) contributors to parent verbal behaviors throughout pediatric venipuncture. HRV was used as a measure of emotion regulation capacity and examined as a moderator in the associations between parent psychological factors and their behaviors, and between child and parent behaviors. Sixty-one children aged 7 to 12 years who presented at an outpatient blood lab for venipuncture and a parent participated. Parent baseline HRV, state catastrophizing, and anxiety were measured prior to venipuncture. The procedure was video-recorded for later coding of pairs' verbal behaviors. Strong associations emerged between child behaviors and parent behaviors. Baseline HRV moderated the association between parent catastrophizing and behavior. Social factors remain a strong influence related to parent behaviors. Psychologically, parent negative cognitions differentially related to parent behaviors based on their emotion regulation capacity. Biologically, low baseline HRV may increase the risk that certain parents engage in a constellation of behaviors that simultaneously direct their child's attention toward the procedure and inadvertently communicate parental worry, fear, or concern.

ABSTRACT

Needle procedures are common throughout childhood and often elicit distress in children and parents. Heart rate variability (HRV), as an index of emotion regulation, can inform both self-regulatory and co-regulatory processes. Mindfulness may serve to regulate distress; however, no research has studied mindfulness or parent and child regulatory responding concurrently during venipuncture. Stemming from a randomized controlled trial investigating a mindfulness intervention, this study sought to describe regulatory responding (via HRV) throughout pediatric venipuncture and the role of cognitive-affective factors (mindfulness, parent anxiety, catastrophizing) in 61 parent-child dyads (7-12 years). We examined (1) patterns of parent and child HRV throughout venipuncture and whether a brief, randomly assigned audio-guided mindfulness versus control exercise affected this pattern and (2) the extent to which changes in parent and child HRV were synchronized throughout venipuncture, and whether parent catastrophizing and anxiety moderated this association. HRV differed as a function of procedural phase. Practicing the mindfulness versus control exercise did not consistently affect HRV in dyads. Positive synchrony was observed during the end of the intervention in dyads with high parental catastrophizing. Otherwise, a pattern of nonsynchrony emerged. Results provide foundational knowledge regarding children's internal (self) and external (parent) regulation mechanisms. RCT registration: NCT03941717.

ABSTRACT

One challenge when communicating science to practitioners and the general public is accurately representing statistical results. In particular, describing the meaning of statistical significance to a non-scientific audience is especially difficult given the technical nature of a correct definition. Correct interpretations of statistical significance can be unintuitive, nuanced, and use unfamiliar technical language. As a result, when researchers are tasked with providing short and understandable interpretations of statistical significance it can be tempting to default to convenient but incorrect interpretations. In the current paper, we offer a concise, simple, and correct interpretation of statistical significance that is suitable for communications targeting a general audience.

ABSTRACT

A challenge when interpreting replications is determining whether the results of a replication "successfully" replicate the original study. Looking for consistency between two studies is challenging because individual studies are susceptible to many sources of error that can cause study results to deviate from each other and the population effect in unpredictable directions and magnitudes. In the current paper, we derive methods to compute a prediction interval, a range of results that can be expected in a replication due to chance (i.e., sampling error), for means and commonly used indexes of effect size: correlations and d-values. The prediction interval is calculable based on objective study characteristics (i.e., effect size of the original study and sample sizes of the original study and planned replication) even when sample sizes across studies are unequal. The prediction interval provides an a priori method for assessing if the difference between an original and replication result is consistent with what can be expected due to sample error alone. We provide open-source software tools that allow researchers, reviewers, replicators, and editors to easily calculate prediction intervals.

ABSTRACT

OBJECTIVE: The aim of this longitudinal study was to examine gender differences in children's hazard-directed behaviors when the parent was absent and determine whether parent reactions when present differentially influences boys' and girls' subsequent behaviors. METHOD: Children and parents were video recorded in their home when a contrived burn hazard ('Gadget') was within view and reach of the child and the parent was sometimes present and absent. Videos were coded for teaching- and discipline-focused reactions by parents when children approached the Gadget in the parent's presence and children's hazard-directed behaviors when the parent was absent. Data were gathered monthly for a period of up to 6 months. RESULTS: Multilevel regression analyses examining temporal relationships between parents' reactions (teaching, discipline) and children's hazard-directed behaviors when the parent was absent revealed significant gender differences. For boys, reductions in hazard-directed behaviors over time were predicted from high teaching or low discipline reactions, with low teaching and high discipline reactions maintaining injury-risk behaviors over time. For girls, reductions in hazard-directed behaviors over time were predicted from low teaching or high discipline reactions, with high teaching and low discipline reactions maintaining injury-risk behaviors over time. CONCLUSION: To moderate young boys' injury-risk behaviors, caregivers should avoid frequent discipline-focused reactions in favor of frequent teaching when the child engages in injury-risk behaviors. For girls, however, frequent discipline-focused reactions reduced injury-risk behaviors over time more effectively than frequent teaching-focused reactions that sustained girls' interest in the hazard. Implications for injury prevention are discussed. (PsycINFO Database Record

ABSTRACT

OBJECTIVE: The aim of this longitudinal study was to determine how children's participation in swim lessons impacts parents' appraisals of children's drowning risk and need for supervision. METHOD: Parents with 2-5-year old children enrolled in community swim lessons completed the same survey measures up to 4 times over an 8-month period. RESULTS: Multilevel regression analyses examining temporal relationships between parents' perceptions of their child's swim ability, supervision needs around water, and children's ability to keep themselves safe in drowning risk situations revealed that as children progressed through swim lessons, parents' perceptions of their child's swim ability and their belief that children are capable of keeping themselves safe around water increased. Further, the relation between parents' perceptions of swim ability and judgments of children's supervision needs was mediated through parents' judgment about their child's ability to secure their own safety near water. CONCLUSIONS: As parents perceive their child to be accumulating swim skills, they increasingly believe that children are capable of keeping themselves from drowning, and as a result, that less active parent supervision of their child is necessary. Implications of these findings for intervention efforts to counter this unwelcome way of thinking that may arise through continued participation in swim lessons are discussed. Incorporating a parent-focused component into children's learn-to-swim programs to promote more realistic appraisals of children's supervision needs and drowning risks may further enhance the positive benefits that swim lessons have for children's safety.

ABSTRACT

Failures to replicate published psychological research findings have contributed to a "crisis of confidence." Several reasons for these failures have been proposed, the most notable being questionable research practices and data fraud. We examine replication from a different perspective and illustrate that current intuitive expectations for replication are unreasonable. We used computer simulations to create thousands of ideal replications, with the same participants, wherein the only difference across replications was random measurement error. In the first set of simulations, study results differed substantially across replications as a result of measurement error alone. This raises questions about how researchers should interpret failed replication attempts, given the large impact that even modest amounts of measurement error can have on observed associations. In the second set of simulations, we illustrated the difficulties that researchers face when trying to interpret and replicate a published finding. We also assessed the relative importance of both sampling error and measurement error in producing variability in replications. Conventionally, replication attempts are viewed through the lens of verifying or falsifying published findings. We suggest that this is a flawed perspective and that researchers should adjust their expectations concerning replications and shift to a meta-analytic mind-set.

ABSTRACT

Centrosomes nucleate and organize interphase microtubules and are instrumental in mitotic bipolar spindle assembly, ensuring orderly cell cycle progression with accurate chromosome segregation. We report that the multifunctional structural protein 4.1R localizes at centrosomes to distal/subdistal regions of mature centrioles in a cell cycle-dependent pattern. Significantly, 4.1R-specific depletion mediated by RNA interference perturbs subdistal appendage proteins ninein and outer dense fiber 2/cenexin at mature centrosomes and concomitantly reduces interphase microtubule anchoring and organization. 4.1R depletion causes G(1) accumulation in p53-proficient cells, similar to depletion of many other proteins that compromise centrosome integrity. In p53-deficient cells, 4.1R depletion delays S phase, but aberrant ninein distribution is not dependent on the S-phase delay. In 4.1R-depleted mitotic cells, efficient centrosome separation is reduced, resulting in monopolar spindle formation. Multipolar spindles and bipolar spindles with misaligned chromatin are also induced by 4.1R depletion. Notably, all types of defective spindles have mislocalized NuMA (nuclear mitotic apparatus protein), a 4.1R binding partner essential for spindle pole focusing. These disruptions contribute to lagging chromosomes and aberrant microtubule bridges during anaphase/telophase. Our data provide functional evidence that 4.1R makes crucial contributions to the structural integrity of centrosomes and mitotic spindles which normally enable mitosis and anaphase to proceed with the coordinated precision required to avoid pathological events.
