Protecting Sexual Minority Youth from Research Risks: Conflicting Perspectives

We describe the dilemmas we encountered in the informed consent process for an HIV prevention project targeting Black gay, bisexual, and non-gay identified young men. We highlight the complexities of applying informed parental consent procedures to sexual minority youth and identify some of the challenges that researchers who work with sexual minority youth face when they must balance the needs and rights of this population against the needs and rights accorded to parents by federal guidelines for protecting minor participants in research.     

A note on time-frequency analysis of finger tapping

Finger tapping involves 3 important features: time, spatial amplitude, and frequency. In classical analysis, investigators examine timing parameters; in spectral analysis, they examine frequency parameters. Both types of analysis are based on stationary tap information. The authors propose that time-frequency analysis is a useful tool for analyzing nonstationary finger tapping. They describe the method and give examples of frequency modulation, age difference, and speed transition that demonstrate additional insights one can gain by using this analysis.     

Comparison of alternative estimation methods in confirmatory factor analyses of the General Health Questionnaire

This paper examines the implications of violating assumptions concerning the continuity and distributional properties of data in establishing measurement models in social science research. The General Health Questionnaire-12 uses an ordinal response scale. Responses to the GHQ-12 from 201 Hong Kong immigrants on arrival in Australia showed that the data were not normally distributed. A series of confirmatory factor analyses using either a Pearson product-moment or a polychoric correlation input matrix and employing either maximum likelihood, weighted least squares or diagonally weighted least squares estimation methods were conducted on the data. The parameter estimates and goodness-of-fit statistics provided support for using polychoric correlations and diagonally weighted least squares estimation when analyzing ordinal, nonnormal data.     

Gender differences in unrealistic optimism about marriage and divorce: are men more optimistic and women more realistic?

Two studies (n = 497) examine gender differences in "unrealistic optimism" in beliefs of marriage using a Taiwanese population. Unrealistic optimism is defined as the beliefs that positive (negative) events are more (less) likely to happen to one's self versus others. Although the bias is robust, it has been shown to be lower among people with an interdependent orientation, specifically those from a collectivist culture (e.g., Taiwan). We find that the unrealistic optimism bias is stronger (Study 1) and more resilient to change when base rates are provided (Study 2) for men as compared to women. Results are consistent with the interpretation that men have a less relationally interdependent self-construal than women. Theoretical implications for unrealistic optimism, cross-cultural psychology, as well as gender differences are discussed.     

A Preliminary Investigation of the Relationship Between Fluency and Application for Multiplication

Research suggests component skill performance has a strong positive relationship with composite skill performance. This study examined the association between accuracy and fluency for the component-composite relationship within multiplication. One hundred and fifty-seven fifth-graders did one-minute assessments for single-digit, and multi-digit multiplication problems. The results demonstrated the students achieved high levels of accuracy but low levels of fluency. Strong correlations between the component-composite skill fluency suggest that fluent component skills may have a significant role in composite skill performance. Moderate/low correlations between component and composite skill accuracy indicate that more than one skill component may contribute to composite skill acquisition.     

The Children's Dual Emotion Regulation Strategy scale: An integrated perspective of Western and East Asian cultures

The literature on emotion regulation in general lacks cultural and contextual sensitivity and is mainly focused on adult participants. Therefore, we developed the Children's Dual Emotion Regulation Strategy (CDERS) scale as a scenario-based measurement that integrates Western and East Asian cultural perspectives. In Study 1 (N = 1120), six interpersonal conflict scenarios were generated, and each scenario consisted of four emotion regulation strategies (i.e., expression, forbearance, impulsiveness, and suppression), thereby including 24 items in total. A confirmatory factor analysis confirmed the four-factor structure. Concurrent validity revealed that the four strategies in the CDERS accounted for 18%–20% of the variance in predicting positive self-concept and life adjustment. In Study 2 (N = 319), predictive validity revealed that CDERS accounted for 12%–16% of the variance in predicting six outcomes. Incremental validity showed that the CDERS significantly accounted for an additional 3%–11% of the variance in predicting all outcomes above and beyond the existing Western and East Asian emotion regulation measures. The CDERS subscales showed acceptable internal and test–retest reliability. In summary, these studies suggest that the CDERS is a reliable and valid measure. The implications of the results point out suggestions for culturally sensitive practices.     

Toddlers' self-regulation development from 14 to 26 months: The unique role of paternal discipline

Toddlerhood is a critical period for children's self-regulation development during which parenting is undoubtedly a key influencing factor. The role that parents especially fathers play in shaping the emergence of self-regulation is still under investigation. This longitudinal study was carried out in 38 families in China, in which toddlers and both parents participated in two waves of observations during home visits, one performed when the toddlers were around 14 months old and another one 12 months later. Children's self-regulation was measured by behaviour control and Stroop tasks. Parental positive and negative discipline was coded by videotaped parent–child interactions. Results indicated that the mothers showed more positive discipline than the fathers at child 14 months, and there were no significant differences in positive and negative discipline between the fathers and mothers at child 26 months, neither in their negative discipline at child 14 months. Only the fathers' positive and negative discipline at child 14 months both significantly predicted toddlers' behaviour control at 26 months—over and above maternal discipline. This study reveals fathers' unique and irreplaceable contributions to children's early self-regulation development.     

Contributions of linguistic,quantitative, and spatial attention skills to young children's math versus reading: Same,different, or both?

The study used Bayesian and Frequentist methods to investigate whether the roles of linguistic, quantitative, and spatial attention skills are distinct in children's acquisition of reading and math. A sample of 175 Chinese kindergarteners was tested with measures of linguistic skills (phonological awareness and phonological memory), quantitative knowledge (number line task, symbolic digit comparison, and non-symbolic number estimation), spatial attention skills (visual span, mental rotation, and visual search), word reading, and calculation. After statistically controlling for age and nonverbal intelligence, phonological awareness and digit comparison performance explained unique variance in both math and reading. Moreover, number line estimation was specifically important for math, while phonological memory was specifically essential for reading. These findings highlight the possibility of developing early screening tools with different cognitive measures for children at risk of learning disabilities in reading and/or math.     

Risk perception and conspiracy theory endorsement predict compliance with COVID-19 public health measures

Public health measures such as spatial distancing and physical hygiene have been found effective in mitigating the spread of the coronavirus. However, there is considerable variability in individual compliance with such public health measures and factors contributing to these interindividual differences are currently still understudied. The present study set out to determine the role of risk perception and conspiracy theory endorsement on compliance with COVID-19 public health measures and explored variations in these associations across participant age and the developmental status of a country, leveraging a large multi-national data set (N = 45,772) across 66 countries/territories, collected via online survey during the early phase of the COVID-19 pandemic (between April and May 2020). Human Development Index (HDI), developed by the United Nations Development Program, was used as a proxy of a country's achievement in key dimensions of human development. Overall, higher risk perception was associated with greater compliance, particularly in individuals with greater conspiracy theory endorsement. Specifically, people from more developed countries who perceived themselves less at risk but showed stronger conspiracy theory endorsement reported the lowest compliance with COVID-19 public health measures. Findings from this study advance understanding of the interplay between risk perception and conspiracy theory endorsement in their effect on compliance with COVID-19 public health measures, under consideration of both individual-level and country-level demographic variables and have potential to inform the design of tailored interventions to fight the current and future global pandemics.     

Spatial attention based on 2D location and relative depth order modulates visual working memory in a 3D environment

The attentional effect on visual working memory (VWM) has been a heated research topic in the past two decades. Studies show that VWM performance for an attended memory item can be improved by cueing its two-dimensional (2D) spatial location during retention. However, few studies have investigated the effect of attentional selection on VWM in a three-dimensional setting, and it remains unknown whether depth information can produce beneficial attentional effects on 2D visual representations similar to 2D spatial information. Here we conducted four experiments, displaying memory items at various stereoscopic depth planes, and examined the retro-cue effects of four types of cues – a cue would either indicate the 2D or depth location of a memory item, and either in the form of physical (directly pointing to a location) or symbolic (numerically mapping onto a location) cues. We found that retro-cue benefits were only observed for cues directly pointing to a 2D location, whereas a null effect was observed for cues directly pointing to a depth location. However, there was a retro-cue effect when cueing the relative depth order, though the effect was weaker than that for cueing the 2D location. The selective effect on VWM based on 2D spatial attention is different from depth-based attention, and the divergence suggests that an object representation is primarily bound with its 2D spatial location, weakly bound with its depth order but not with its metric depth location. This indicates that attentional selection based on memory for depth, particularly metric depth, is ineffective.
