VEP latency and some properties of simple motor reaction-time distribution

Summary The median of simple motor reaction (RT) to a flash parallels the latencies of visually evoked potential (VEP) deflections if flash intensity is varied. However, mean and median reaction times are not equal because of the skewness of RT distribution. It therefore seemed plausible that the mean reaction time — intensity relationship would be steeper than that for VEP latency. Such divergence would account for the intensity-dependent motor component of RT revealed by other psychophysical studies. The latencies of VEP deflections were measured as a function of intensity and the results were compared with mean and median RTs. The difference between mean and median RT is constant and independent of flash intensity. Moreover, both values are parallel to VEP latency. The general pattern of results remains the same after a change in the distribution from which the foreperiod is sampled.     

Three contributions to the two-valued propositional calculus

Summary Three chapters contain the results independent of each other. In the first chapter I present a set of axioms for the propositional calculus which are shorter than the ones known so far, in the second one I give a method of defining all ternary connectives, in the third one, I prove that the probability of propositional functions is preserved under reversible substitutions. This paper appeard orginally under the title “Trois contributions an calcul des propositions bivalent” inStudia Societatis Scientiarum Torunensis, Toruń, Polonia, Sectio A, vol. I (1948), pp. 3–15.     

Is the Association of ADHD with Socio-Economic Disadvantage Explained by Child Comorbid Externalizing Problems or Parent ADHD?

It has been unclear whether an associations of child ADHD with socio-economic disadvantage (SES) could be accounted for by (a) parental ADHD explaining both low SES and child ADHD, and/or (b) the joint overlap of ODD or CD with low SES and ADHD. Study 1 used a community-recruited case-control sample with detailed evaluation of SES indicators, child ADHD, child externalizing, and parent ADHD symptoms (n = 931 children, 521 ADHD, 577 boys, 354 girls) in a path modeling analysis with latent variables. Study 2 evaluated ADHD and externalizing behavior in a regression model using a poverty index for SES, in 70,927 children (48.2% female) aged 5–17 years from the US 2011–2012 National Survey of Children’s Health (NSCH). In Study 1, lower SES was related to the ADHD latent variable, β = ?.18, p < .001; 95%CI [?.25,-.12]. This effect held when parent ADHD and child ODD and CD were in the model, β = ?.11, p < .01, 95% CI [?.09,-.03], equivalent to OR = 1.50, 95% CI[1.12–2.04]). In Study 2, these results replicated. Adjusting only for age and sex, children from families who were below 200% of the federal poverty line were more likely to have moderate or severe ADHD than no ADHD, versus children above that line, OR = 2.13, 95% CI[1.79,2.54], p < .001. The effect held after adjusting for disruptive/externalizing problems, OR = 1.61, p < .01, 95%CI [1.32,1.96]. The effect size for comparable models was similar across both studies, lending higher confidence to the results. It is concluded that the SES association with child ADHD is not explained by artifact and requires a mechanistic explanation.     

What Matters Most to the Left-Behind Children’s Life Satisfaction and School Engagement: Parent or Grandparent?

This study compared the role of the parent and grandparent in the adjustment of children who had, and who had not, been left behind when their parents moved to urban areas for work, and tested whether self-esteem mediated the association between these family relationships and child adjustment. The sample included 428 middle school students in central China, 204 of whom were left-behind children who were cared for by grandparents and 224 of whom were not left behind. The students responded to five questionnaires measuring parent–child relationships, grandparent–child relationships, self-esteem, life satisfaction and school engagement. Regression analyses showed that self-esteem mediated the association between parent–child and grandparent–child relationships and children’s adjustment, but there were different patterns of association for the non-left-behind children and left-behind children groups. Furthermore, the unique effect of parent–child relationships was higher than that of grandparent–child relationships for the non-left-behind children, but for the left-behind children, grandparent–child relationships played a more important role than grandparent–child relationships in predicting their school engagement, and parent–child relationships played a more important role in predicting their life satisfaction. Parents who are far away and grandparents who are close at hand can shape different psychological and behavioral development outcomes of left-behind children.     

Factors Influencing Adolescents’ Self-control According to Family Structure

We compared factors influencing adolescents’ self-control according to their family structure. Participants were 944 adolescents in five cities in South Korea (115 from single-parent families, 65 from grandparent-led families, and 764 from two-parent families). Data were collected using self-report questionnaires containing items on self-control, stress, parenting attitude, parent–adolescent communication, and family cohesion. Data were analyzed using stepwise multiple regressions with SPSS program. The factors influencing adolescents’ self-control differed across the three family structure groups. For single-parent families, stress and parental attitudes were significantly related to adolescents’ self-control (adjusted R²?=?0.37, p?<?0.001). In contrast, for grandparent-led families, family cohesion and parental attitude were significantly related to adolescents’ self-control (adjusted R²?=?0.31, p?<?0.01), while for two-parent families, stress, parental attitude, and parent–adolescent communication were related to the outcome (adjusted R²?=?0.24, p?<?0.001). Parental attitude was thus a common factor relating to self-control, regardless of family structure. On the other hand, the main factors influencing adolescents with low self-control were gender and stress. Our results confirm that adolescents’ self-control is not only affected by personal factors but also by parental and family factors. It is important to improve individual program to improve adolescents’ self-control according to family structure. The results of study may act as a base for improving individual intervention programs aimed at promoting adolescents’ self-control by factoring in family structure.
