School Refusal Behaviors: The Roles of Adolescent and Parental Factors.

School refusal behaviors in adolescents have deleterious immediate and long-term consequences and are associated with mental ill-health such as anxiety and depression. Understanding factors that place youth at higher risk of school refusal behavior may assist in developing effective management approaches. We investigated parental and adolescent factors that may be associated with school refusal behaviors by specifically focusing on the role of parental and adolescent emotion dysregulation, their anxiety and depression, and parental rearing style.

The receiver operating characteristic area under the curve (or mean ridit) as an effect size.

Several authors have recommended adopting the receiver operator characteristic (ROC) area under the curve (AUC) or mean ridit as an effect size, arguing that it measures an important and interpretable type of effect that conventional effect-size measures do not. It is base-rate insensitive, robust to outliers, and invariant under order-preserving transformations. However, applications have been limited to group comparisons, and usually just two groups, in line with the popular interpretation of the AUC as measuring the probability that a randomly chosen case from one group will score higher on the dependent variable than a randomly chosen case from another group.

Understanding Australian Government Risk Communication Early in the COVID-19 Pandemic: Sociodemographics, Risk Attitudes and Media Consumption.

Effective risk communication is essential for government and health authorities to effectively manage public health during the Coronavirus disease (COVID-19) pandemic. Understanding the factors that influence people's perceptions of crisis-related risk messages is critical to identify gaps and inequalities in population risk communication. Using a longitudinal survey of a representative adult sample, we examined risk communication about COVID-19 during April-June 2020 in Australia across sociodemographic groups especially the at-risk groups, accounting for and exploring the effects of risk attitudes and media engagement.

Risk tolerance and changes in coronavirus disease (COVID) related health behaviors: A longitudinal study.

Objective: The present study examined behavioral responses during the coronavirus disease 2019 (COVID-19) pandemic and the role of dispositional risk tolerance in the Australian context.

Method: The study involved a six-wave longitudinal investigation with a nationally representative sample of Australians ( = 1,296). Dispositional risk tolerance was measured at Wave 1 and participants' anxiety level and self-report implementation of 10 COVID actions was assessed in each wave.

The Psychological Benefits of an Uncertain World: Hope and Optimism in the Face of Existential Threat.

We examine how prior mental health predicts hopes and how hopes predict subsequent mental health, testing hypotheses in a longitudinal study with an Australian nation-wide adult sample regarding mental health consequences of the COVID-19 outbreak during its initial stage. Quota sampling was used to select a sample representative of the adult Australian population in terms of age groups, gender, and geographical location. Mental health measures were selected to include those with the best psychometric properties.

Compositional data analysis tutorial.

This article presents techniques for dealing with a form of dependency in data arising when numerical data sum to a constant for individual cases, that is, "compositional" or "ipsative" data. Examples are percentages that sum to 100, and hours in a day that sum to 24. Ipsative scales fell out of fashion in psychology during the 1960s and 1970s due to a lack of methods for analyzing them.

Cause or symptom? A longitudinal test of bidirectional relationships between emotion regulation strategies and mental health symptoms.

Previous work has generally conceptualized emotion regulation as contributing to mental health outcomes, and not vice versa. The present study challenges this assumption by using a prospective design to investigate the directionality of underlying relationships between emotion regulation and mental health in the context of a major population-level stressor. We surveyed a large nationally representative sample of adults (18-91 years, = 704) at three 1-month intervals across the acute lockdown phase of the COVID-19 pandemic in Australia, using standardized measures of depression and anxiety symptoms.

The Effect of COVID-19 on Mental Health and Wellbeing in a Representative Sample of Australian Adults.

There is minimal knowledge about the impact of large-scale epidemics on community mental health, particularly during the acute phase. This gap in knowledge means we are critically ill-equipped to support communities as they face the unprecedented COVID-19 pandemic. This study aimed to provide data urgently needed to inform government policy and resource allocation now and in other future crises.

Measuring children's auditory statistical learning via serial recall.

Statistical learning (SL) has been a prominent focus of research in developmental and adult populations, guided by the assumption that it is a fundamental component of learning underlying higher-order cognition. In developmental populations, however, there have been recent concerns regarding the degree to which many current tasks reliably measure SL, particularly in younger children. In the current article, we present the results of two studies that measured auditory statistical learning (ASL) of linguistic stimuli in children aged 5-8 years.

Impact of uncertainty and ambiguous outcome phrasing on moral decision-making.

The literature has shown that different types of moral dilemmas elicit discrepant decision patterns. The present research investigated the role of uncertainty in contributing to these decision patterns. Two studies were conducted to examine participants' choices in commonly used dilemmas.

Caricaturing can improve facial expression recognition in low-resolution images and age-related macular degeneration.

Previous studies of age-related macular degeneration (AMD) report impaired facial expression recognition even with enlarged face images. Here, we test potential benefits of caricaturing (exaggerating how the expression's shape differs from neutral) as an image enhancement procedure targeted at mid- to high-level cortical vision. Experiment 1 provides proof-of-concept using normal vision observers shown blurred images as a partial simulation of AMD.

Ambiguity and Conflict Aversion When Uncertainty Is in the Outcomes.

We argue that the way ambiguity has been operationalized throughout the literature on ambiguity effects has an important limitation, insofar as ambiguity in outcomes has been neglected. We report two studies where judges do encounter ambiguity in the sampled outcomes and find evidence that ambiguity aversion is not less than when judges are given a range of outcomes without reference to ambiguous outcomes themselves. This result holds regardless of whether people are presented with a sample all at once or sample outcomes sequentially.

Can body temperature dysregulation explain the co-occurrence between overweight/obesity, sleep impairment, late-night eating, and a sedentary lifestyle?

Purpose: Overweight/obesity, sleep disturbance, night eating, and a sedentary lifestyle are common co-occurring problems. There is a tendency for them to co-occur together more often than they occur alone. In some cases, there is clarity as to the time course and evolution of the phenomena.

Groupness in Preverbal Infants: Proof of Concept.

Infant sociability is generally conceived in terms of dyadic capacities and behaviors. Recently, quantitative evidence has been published to support arguments that infants achieve a criterion for groupness: the capacity to interact simultaneously with two others. Such studies equate this capacity with alternating dyadic acts to the two other members of an interacting trio.

CDF-quantile distributions for modelling random variables on the unit interval.

This paper introduces a two-parameter family of distributions for modelling random variables on the (0,1) interval by applying the cumulative distribution function of one 'parent' distribution to the quantile function of another. Family members have explicit probability density functions, cumulative distribution functions and quantiles in a location parameter and a dispersion parameter. They capture a wide variety of shapes that the beta and Kumaraswamy distributions cannot.

Perceived time slows during fleeting fun or fear.

Previous psychophysical studies at durations greater than 1000 ms have confirmed the anecdotal reports of an increase in the perceived duration of both positively and negatively valenced emotive stimuli; however, the results of studies at durations less than 1000 ms have been inconsistent. This study further investigated the effect of valence on the perception of durations less than 1000 ms. We used both positively and negatively valenced stimuli in order to compare their effects on the distortion of duration, and we tested multiple data points within the sub-one-second range.

Asymmetries in Responses to Attitude Statements: The Example of "Zero-Sum" Beliefs.

While much has been written about the consequences of zero-sum (or fixed-pie) beliefs, their measurement has received almost no systematic attention. No researchers, to our awareness, have examined the question of whether the endorsement of a zero-sum-like proposition depends on how the proposition is formed. This paper focuses on this issue, which may also apply to the measurement of other attitudes.

Moderator effects differ on alternative effect-size measures.

This paper discusses largely ignored issues regarding moderation of effect-sizes. We show that, under commonly-occurring conditions, popular alternatives for effect-size measures in ANOVA and multiple regression are not moderated identically across independent samples. Effects may appear to be unmoderated according to one effect-size measure but not according to another, or may even be moderated in opposite directions.

Neural Correlates of Decision-Making Under Ambiguity and Conflict.

HIGHLIGHTS We use a simple gambles design in an fMRI study to compare two conditions: ambiguity and conflict.Participants were more conflict averse than ambiguity averse.Ambiguity aversion did not correlate with conflict aversion.

Adapting to an Uncertain World: Cognitive Capacity and Causal Reasoning with Ambiguous Observations.

Ambiguous causal evidence in which the covariance of the cause and effect is partially known is pervasive in real life situations. Little is known about how people reason about causal associations with ambiguous information and the underlying cognitive mechanisms. This paper presents three experiments exploring the cognitive mechanisms of causal reasoning with ambiguous observations.

When Is Group Membership Zero-Sum? Effects of Ethnicity, Threat, and Social Identity on Dual National Identity.

This paper presents an investigation into marginalizing racism, a form of prejudice whereby ingroup members claim that specific individuals belong to their group, but also exclude them by not granting them all of the privileges of a full ingroup member. One manifestation of this is that perceived degree of outgroup membership will covary negatively with degree of ingroup membership. That is, group membership may be treated as a zero-sum quantity (e.

Probability judgments under ambiguity and conflict.

Whether conflict and ambiguity are distinct kinds of uncertainty remains an open question, as does their joint impact on judgments of overall uncertainty. This paper reviews recent advances in our understanding of human judgment and decision making when both ambiguity and conflict are present, and presents two types of testable models of judgments under conflict and ambiguity. The first type concerns estimate-pooling to arrive at "best" probability estimates.

Effects of question formats on causal judgments and model evaluation.

Evaluation of causal reasoning models depends on how well the subjects' causal beliefs are assessed. Elicitation of causal beliefs is determined by the experimental questions put to subjects. We examined the impact of question formats commonly used in causal reasoning research on participant's responses.

Reasoned Decision Making Without Math? Adaptability and Robustness in Response to Surprise.

Many real-world planning and decision problems are far too uncertain, too variable, and too complicated to support realistic mathematical models. Nonetheless, we explain the usefulness, in these situations, of qualitative insights from mathematical decision theory. We demonstrate the integration of info-gap robustness in decision problems in which surprise and ignorance are predominant and where personal and collective psychological factors are critical.
