Children Use Nonverbal Cues from an Adult to Evaluate Peers.

J Cogn Dev 2018 9;19(2):121-136. Epub 2018 Mar 9.

University of Wisconsin-Madison.

What factors contribute to children's tendency to view individuals as having different traits and abilities? The present research tested whether young children are influenced by adults' nonverbal behaviors when making inferences about peers. In Study 1, participants (5-6 years) viewed multiple videos of interactions between a 'teacher' and two 'students;' all individuals were unfamiliar to participants. In each clip, the students behaved similarly, but the teacher did not: She either smiled, nodded, touched, or shook her head at one student, and looked at the other student with a neutral expression.

College of Animal Science, Zhejiang University, Hangzhou 310058, Zhejiang, China. Electronic address:

In group I nucleopolyhedrovirus such as Bombyx mori nucleopolyhedrovirus (BmNPV), the biological functions of F-like protein (Bm14) still remain elusive. Here, we found that the deletion of Bm14 reduced the production rate of infectious budded viruses in cell culture, delayed the lethal time of infected larvae by approximately 26 h, and produced less occlusion bodies (OBs). Scanning electron microscopy demonstrated that its disruption affected OB morphogenesis, forming irregular OBs with a pitted surface and irregular profiles. Read More

Bioaccessibility of Drug Residues on Common Police Station Work Surfaces.

J Anal Toxicol 2018 Oct 6. Epub 2018 Oct 6.

School of Agricultural and Wine Sciences, Institute for Land, Water and Society, Charles Sturt University, Wagga Wagga, NSW, Australia.

The fraction of any surface-adsorbed contaminant available for absorption is considered the bioaccessible fraction. Applied previously to contaminants such as pesticides and heavy metals on surfaces such as soil, food and cosmetics, the term may also be used to describe the fraction of drug residue bound to work surfaces which may be mobilized via contact transfer with human skin. Police station work surfaces have been shown to commonly contain low levels of drug residues as thin films; however, no information is available on how readily these residues may be transferred to human skin during direct or glancing contact.

New improved gamma: Enhancing the accuracy of Goodman-Kruskal's gamma using ROC curves.

Behav Res Methods 2018 Sep 27. Epub 2018 Sep 27.

, Cupertino, CA, USA.

For decades, researchers have debated the relative merits of different measures of people's ability to discriminate the correctness of their own responses (resolution). The probabilistic approach, primarily led by Nelson, has advocated the Goodman-Kruskal gamma coefficient, an ordinal measure of association. The signal detection approach has advocated parametric measures of distance between the evidence distributions or the area under the receiver operating characteristic (ROC) curve. Read More

The influence of threat on perceived spatial distance to out-group members.

Psychol Res 2018 Sep 6. Epub 2018 Sep 6.

Social Cognition Center Cologne, University of Cologne, Cologne, Germany.

A classic example of discriminatory behavior is keeping spatial distance from an out-group member. To explain this social behavior, the literature offers two alternative theoretical options that we label as the "threat hypothesis" and the "shared-experience hypothesis". The former relies on studies showing that out-group members create a sense of alertness. Read More

Battle of the Mondrians: Investigating the Role of Unpredictability in Continuous Flash Suppression.

Iperception 2018 Jul-Aug;9(4):2041669518792930. Epub 2018 Aug 22.

Department of Psychology, Vanderbilt University, Nashville, TN, USA.

In continuous flash suppression (CFS), a dynamic sequence of Mondrian patterns presented to one eye suppresses a static target in the other eye for several seconds at a time. Its effectiveness has been linked to low-level properties such as spatial frequency and orientation, but the role of higher order influences remains unstudied. Here, using a tracking paradigm, we asked if the spatial and temporal predictability of the Mondrian sequence affects CFS dynamics. Read More

Scand J Pain 2013 Oct 1;4(4):243-246. Epub 2013 Oct 1.

David Chestnut, M.D., Section on the History of Anesthesia, Department of Anesthesiology, University of Alabama School of Medicine at Birmingham, JT 845, 619 19th Street South, Birmingham, AL 35294, USA.

Background The United States Civil War (1861-1865) pitted the more populous industrialized North (Union) against the mainly agricultural slaveholding South (Confederacy). This conflict cost an enormous number of lives, with recent estimates mentioning a total mortality greater than 700,000 combatants [1]. Although sulfuric ether (ETH) and chloroform (CHL) were available since Morton's use of the former in 1846 and the employment of the latter in 1847, and even though inhalational agents were used in Crimean war (1853-1856) and the Mexican-American War (1846-1848), the United States Civil War gave military surgeons on both sides the opportunity to experience the use of these two agents because of the large number of casualties.

J Exp Psychol Hum Percept Perform 2018 Aug 3;44(8):1258-1267. Epub 2018 May 3.

Rutgers University-Newark.

The light reaching the eye from a surface does not indicate the black-gray-white shade of a surface (called lightness) because the effects of illumination level are confounded with the reflectance of the surface. Rotating a gray paper relative to a light source alters its luminance (intensity of light reaching the eye) but the lightness of the paper remains relatively constant. Recent publications have argued, as had Helmholtz (1866/1924), that the visual system unconsciously estimates the direction and intensity of the light source. Read More

Department of Psychology, University of Massachusetts Boston, 100 Morrissey Blvd., Boston, MA 02125.

What drives infants' attention in complex visual scenes? Early models of infant attention suggested that the degree to which different visual features were detectable determines their attentional priority. Here, we tested this by asking whether two targets - defined by different features, but each equally salient when evaluated independently - would drive attention equally when pitted head-to-head. In Experiment 1, we presented 6-month-old infants with an array of gabor patches in which a target region varied either in color or spatial frequency from the background. Read More

How distinct are visual memory representations from visual perception? Although evidence suggests that briefly remembered stimuli are represented within early visual cortices, the degree to which these memory traces resemble true visual representations remains something of a mystery. Here, we tested whether both visual memory and perception succumb to a seemingly ubiquitous neural computation: normalization. Observers were asked to remember the contrast of visual stimuli, which were pitted against each other to promote normalization either in perception or in visual memory. Read More

Explaining recollection without remembering.

J Exp Psychol Learn Mem Cogn 2018 Dec 1;44(12):1921-1930. Epub 2018 Feb 1.

Department of Human Development and Human Neuroscience Institute, Cornell University.

Recollection without remembering is a counterintuitive phenomenon that violates a traditional assumption of source memory models-namely, that accurate item memory is a necessary precondition for remembering source details that accompanied an item's presentation. The dual-recollection model explains recollection without remembering as a by-product of the contrasting effects of target and context recollection on item tests versus source tests. We pitted that explanation against 2 others that preserve the traditional assumption, one based on hypothesized testing artifacts and the other derived from multivariate signal detection theory.

An Experimental Evaluation of Competing Age-Predictions of Future Time Perspective between Workplace and Retirement Domains.

Front Psychol 2017 9;8:2316. Epub 2018 Jan 9.

Quantitative Psychology, Georgia Institute of Technology, Atlanta, GA, United States.

Future time perspective (FTP) is defined as "perceptions of the future as being limited or open-ended" (Lang and Carstensen, 2002; p. 125). The construct figures prominently in both workplace and retirement domains, but the age-predictions are competing: Workplace research predicts decreasing FTP age-change, in contrast, retirement scholars predict increasing FTP age-change.

A Computational Account of Optimizing Social Predictions Reveals That Adolescents Are Conservative Learners in Social Contexts.

J Neurosci 2018 Jan 18;38(4):974-988. Epub 2017 Dec 18.

Autism and Neurodevelopmental Disorders Institute, George Washington University and Children's National Health System, Washington, DC 20052.

As adolescents transition to the complex world of adults, optimizing predictions about others' preferences becomes vital for successful social interactions. Mounting evidence suggests that these social learning processes are affected by ongoing brain development across adolescence. A mechanistic understanding of how adolescents optimize social predictions and how these learning strategies are implemented in the brain is lacking. Read More

A meta-analysis of work-family conflict and social support.

Psychol Bull 2018 Mar 14;144(3):284-314. Epub 2017 Dec 14.

Department of Psychology, University of Georgia.

The relationship between social support and work-family conflict is well-established, but the notion that different forms, sources, and types of social support as well as contextual factors can alter this relationship has been relatively neglected. To address this limitation, the current study provides the most comprehensive and in-depth examination of the relationship between social support and work-family conflict to date. We conduct a meta-analysis based on 1021 effect sizes and 46 countries to dissect the social support and work-family conflict relationship. Read More

The Primary Role of Flow Processing in the Identification of Scene-Relative Object Movement.

J Neurosci 2018 Feb 11;38(7):1737-1743. Epub 2017 Dec 11.

Neural Science Program, NYU-ECNU Institute of Brain and Cognitive Science, New York University Shanghai, Shanghai, People's Republic of China

Retinal image motion could be due to the movement of the observer through space or an object relative to the scene. Optic flow, form, and change of position cues all provide information that could be used to separate out retinal motion due to object movement from retinal motion due to observer movement. In Experiment 1, we used a minimal display to examine the contribution of optic flow and form cues. Read More

Successful treatment of facial milia in an infant with orofaciodigital syndrome type 1.

Pediatr Dermatol 2018 Jan 3;35(1):e88-e89. Epub 2017 Dec 3.

Department of Dermatology and Dermatologic Surgery, Medical University of South Carolina, Charleston, SC.

We report the successful treatment of multiple facial milia with manual extraction and tretinoin in a child with orofaciodigital syndrome type 1. Treatment with topical medications may be insufficient in individuals with orofaciodigital syndrome type 1, and pitted scarring is often a sequala. This case demonstrates that manual extraction is well tolerated and effective in the treatment of multiple milia. Read More
