Waste Aversion Reduces Inequity Aversion Among Chinese Children.

Child Dev 2021 May 13. Epub 2021 May 13.

Hebrew University of Jerusalem.

An underlying aspect of the development of fairness is the aversion to unequal treatment toward equally deserving parties. By middle childhood, children from Western cultures are even willing to discard resources to avoid inequity. Here, a series of four studies were conducted to assess the robustness of inequity aversion in a culture that emphasizes the value of "Thrift" (i. Read More

Authors:
Alynda N Wood

J Neurophysiol 2021 May 12. Epub 2021 May 12.

Emory University, United Statesgrid.189967.8.

Motor learning is a core aspect of human life, and appears to be ubiquitous throughout the animal kingdom. Dopamine, a neuromodulator with a multifaceted role in synaptic plasticity, may be a key signaling molecule for motor skill learning. Though typically studied in the context of reward-based associative learning, dopamine appears to be necessary for some types of motor learning. Read More

Micro-Hole Generation by High-Energy Pulsed Bessel Beams in Different Transparent Materials.

Micromachines (Basel) 2021 Apr 18;12(4). Epub 2021 Apr 18.

Istituto di Fotonica e Nanotecnologie (IFN)-CNR, Udr di Como, Via Valleggio 11, 22100 Como, Italy.

Micro-drilling transparent dielectric materials by using non-diffracting beams impinging orthogonally to the sample can be performed without scanning the beam position along the sample thickness. In this work, the laser micromachining process, based on the combination of picosecond pulsed Bessel beams with the trepanning technique, is applied to different transparent materials. We show the possibility to create through-apertures with diameter on the order of tens of micrometers, on dielectric samples with different thermal and mechanical characteristics as well as different thicknesses ranging from two hundred to five hundred micrometers.

The feeling of "kiki": Comparing developmental changes in sound-shape correspondence for audio-visual and audio-tactile stimuli.

J Exp Child Psychol 2021 Apr 26;209:105167. Epub 2021 Apr 26.

Department of Psychology, Developmental and Brain Sciences, University of Massachusetts Boston, Boston, MA 02125, USA. Electronic address:

Sound-shape crossmodal correspondence, the naturally occurring associations between abstract visual shapes and nonsense sounds, is one aspect of multisensory processing that strengthens across early childhood. Little is known regarding whether school-aged children exhibit other variants of sound-shape correspondences such as audio-tactile (AT) associations between tactile shapes and nonsense sounds. Based on previous research in blind individuals suggesting the role of visual experience in establishing sound-shape correspondence, we hypothesized that children would show weaker AT association than adults and that children's AT association would be enhanced with visual experience of the shapes.

Front Mol Biosci 2021 12;8:643004. Epub 2021 Apr 12.

Department of Pharmacology, Institute of Pharmacy, Nirma University, Ahmedabad, India.

As of September 19, 2020, about 30 million people have been infected with the novel corona virus disease 2019 (COVID-19) globally, and the numbers are increasing at an alarming rate. The disease has a tremendous impact on every aspect of life, but one of the biggest, related to human health and medical sciences, is its effect on cancer. Nearly 2% of the total COVID-19 patients prior to May 2020 had cancer, and the statistics are quite frightening as the patient can be referred to as "doubly unfortunate" to suffer from cancer with the added misery of infection with COVID-19.

Does mercury emission from small-scale gold mining cause widespread soil pollution in Ghana?

Environ Pollut 2021 Mar 22;284:116945. Epub 2021 Mar 22.

Aarhus University, Department of Bioscience, Velsoevej 25, 8600, Silkeborg, Denmark. Electronic address:

The use of mercury in small-scale gold mining is globally the largest anthropogenic source of mercury in the environment. In countries like Ghana, where small-scale gold mining is a highly important economic sector, the activity is also expected to cause local pollution. This study is based on a hypothesis that the mining activity in Ghana is causing more widespread soil pollution also outside active mining sites, and that the main part of regional differences in soil concentrations of mercury might come from pollution.

The contribution of sluggish cognitive tempo to processing speed in survivors of pediatric brain tumors.

Child Neuropsychol 2021 Apr 18:1-13. Epub 2021 Apr 18.

Kennedy Krieger Institute Neuropsychology Department.

Sluggish Cognitive Tempo (SCT) describes a pattern of under-activity, poor initiation, and slowness. It was first reported within the Attention Deficit Hyperactivity Disorder (ADHD) literature and found to be positively associated with the inattentive symptoms of ADHD and negatively or not significantly associated with the hyperactivity/impulsivity symptoms of ADHD. SCT has since been considered applicable to the pediatric oncology population given the emergence of inattentive, sluggish symptoms secondary to cancer treatment. Read More

Teaching comprehension of double-meaning jokes to young children.

J Appl Behav Anal 2021 Apr 12. Epub 2021 Apr 12.

California State University, Fresno.

Various forms of humor are an important aspect of social interactions, even at an early age. Humor comprehension is a repertoire that is said to emerge between the ages of 7 and 11 years, and this is primarily attributed to a child's level of cognitive development. The behavioral literature has suggested that various forms of complex verbal behavior, including the use and comprehension of humor, are learned operants that can be taught using systematic teaching procedures.
