Development of neural responses to hearing their own name in infants at low and high risk for autism spectrum disorder

The own name is a salient stimulus, used by others to initiate social interaction. Typically developing infants orient towards the sound of their own name and exhibit enhanced event-related potentials (ERP) at 5 months. The lack of orientation to the own name is considered to be one of the earliest signs of autism spectrum disorder (ASD). In this study, we investigated ERPs to hearing the own name in infants at high and low risk for ASD, at 10 and 14 months. We hypothesized that low-risk infants would exhibit enhanced frontal ERP responses to their own name compared to an unfamiliar name, while high-risk infants were expected to show attenuation or absence of this difference in their ERP responses. In contrast to expectations, we did not find enhanced ERPs to own name in the low-risk group. However, the high-risk group exhibited attenuated frontal positive-going activity to their own name compared to an unfamiliar name and compared to the low-risk group, at the age of 14 months. These results suggest that infants at high risk for ASD start to process their own name differently shortly after one year of age, a period when frontal brain development is happening at a fast rate

The detection of communicative signals directed at the self in infant prefrontal cortex

A precondition for successful communication between people is the detection of signals indicating the intention to communicate, such as eye contact or calling a person's name. In adults, establishing communication by eye contact or calling a person's name results in overlapping activity in right prefrontal cortex, suggesting that, regardless of modality, the intention to communicate is detected by the same brain region. We measured prefrontal cortex responses in 5-month-olds using near-infrared spectroscopy (NIRS) to examine the neural basis of detecting communicative signals across modalities in early development. Infants watched human faces that either signaled eye contact or directed their gaze away from the infant, and they also listened to voices that addressed them with their own name or another name. The results revealed that infants recruit adjacent but non-overlapping regions in the left dorsal prefrontal cortex when they process eye contact and own name. Moreover, infants that responded sensitively to eye contact in the one prefrontal region were also more likely to respond sensitively to their own name in the adjacent prefrontal region as revealed in a correlation analysis, suggesting that responding to communicative signals in these two regions might be functionally related. These NIRS results suggest that infants selectively process and attend to communicative signals directed at them. However, unlike adults, infants do not seem to recruit a common prefrontal region when processing communicative signals of different modalities. The implications of these findings for our understanding of infants’ developing communicative abilities are discussed

Libraries and Student Retention

Mick Williams presented the workshop “Libraries and Student Retention” at the June 2015 Association of Christian Librarians Conference. This article of the same name encapsulates key points that were shared during the workshop’s PowerPoint presentation on how academic librarians can actively promote student retention at their own institutions of higher learning

Iacopo Sannazaro and the Creation of a Poetic Canon in Early Modern England

This article investigates the circulation and fame of Sannazaro\u2019s Arcadia in early modern England, focusing first on Philip Sidney\u2019s reception of the poem as part of an ongoing pastoral tradition. Sannazaro\u2019s work thus contributed to create a new poetic context and decisively influenced Sidney\u2019s own Arcadia. Significantly enough, after Sidney\u2019s death the name of Sannazaro seems to suffer a deliberate act of ostracism (he does not appear in the works of Sidneian followers and commentators) as if Sidney\u2019s scribal community preferred to exalt the name of their friend and patron by marginalizing one of Sidney\u2019s sources

Atypical neural responding to hearing one’s own name in adults with ASD

Diminished responding to hearing one's own name is one of the earliest and strongest predictors of autism spectrum disorder (ASD). Here, we studied, for the first time, the neural correlates of hearing one's own name in ASD. Based on existing research, we hypothesized enhancement of late parietal positive activity specifically for the own name in neurotypicals, and for this effect to be reduced in adults with ASD. Source localization analyses were conducted to estimate group differences in brain regions underlying this effect. Twenty-one adults with ASD, and 21 age-and gender-matched neurotypicals were presented with 3 categories of names (own name, close other, unknown other) as task-irrelevant deviant stimuli in an auditory oddball paradigm while electroencephalogram was recorded. As expected, late parietal positivity was observed specifically for own names in neurotypicals, indicating enhanced attention to the own name. This preferential effect was absent in the ASD group. This group difference was associated with diminished activation in the right temporoparietal junction (rTPJ) in adults with ASD. Further, a familiarity effect was found for N1 amplitude, with larger amplitudes for familiar names (own name and close other). However, groups did not differ for this effect. These findings provide evidence of atypical neural responding to hearing one's own name in adults with ASD, suggesting a deficit in self-other distinction associated with rTPJ dysfunction

What’s in a Name?

Plenty. This paper analyzes two broad questions: Does your first name matter? And how did you get your first name anyway? Using data from the National Opinion Research Centers (NORC’s) General Social Survey, including access to respondents first names from the 1994 and 2002 surveys, we extract the important “first name features” (FNF), e.g. popularity, number of syllables, phonetic features, Scrabble score, “blackness” (i.e. the fraction of people with that name who are black), etc ... We then explore whether these first name features are useful explanatory factors of a respondent’s exogenous background factors (sex, race, parents’ education, etc...) and lifetime outcomes (e.g. financial status, occupational prestige, perceived social class, education, happiness, and whether they became a parent before 25). We find that first name features on their own do have significant predictive power for a number of these lifetime outcomes, even after controlling for a myriad of exogenous background factors. We find evidence that first name features are independent predictors of lifetime outcomes that are likely related to labor productivity such as education, happiness and early fertility. Importantly, however, we also find evidence based on the differential impacts of gender and race on the blackness of a name and its popularity that suggest that discrimination may also be a factor.names, identity, discrimination

Portrait of Professor Breidenbaugh

People often do not see what is right in front of them; objects that are passed by everyday are often unnoticed. People are not necessarily unobservant, but are probably more absorbed with their own activities. One object that is hidden in plain sight on the Gettysburg College campus is the portrait of Professor Edward S. Breidenbaugh that hangs in the Science Center. The name Breidenbaugh is commonly known amongst the students at Gettysburg because of the building in his name, Breidenbaugh Hall. However, the history behind Breidenbaugh and his portrait is not as commonly known as the name, but is important in understanding his influence at Gettysburg College.

‘Not in My Name’ Claims of Constitutional Right

We have a constitutional right against the state forcing us to be associated with expression with which we do not wish to be associated. The freedom of expressive association is not stated in our Constitution’s text. Rather, it is derived from various provisions of the First Amendment. As the freedom of speech protects, among other things, our right to shape how we present ourselves to the world, so does the freedom of expressive association protect us from the state shaping us by connecting us to ideas not of our choosing. Our freedom of expressive association allows us to claim an idea as our own, and to say “that idea is not mine . . . and you may not say it in my name.” This “not in my name” conception of constitutional right has iterations in several areas of First Amendment law: compelled speech, compelled subsidies for speech, and the Establishment Clause. Compelled support for government speech, though, is valid, because the state speaks in the name of its citizens. The understanding of expressive association as undergirding “not in my name” claims of constitutional right allows us to solve two lingering problems of misattribution in the compelled subsidies for speech and Establishment Clause case law. But whether or not misattribution is present, we maintain a broad presumptive right against the state’s advancing ideas in our name

Narcissism

Excerpt: Narcissism takes its name from the legendary figure Narcissus, who fell in love with his own reflection in a woodland pool and pined away in unrequited love, and has come to refer to self-love. It involves a vain and grandiose selfcentredness, and auto-eroticism, *hedonism, vanity, exhibitionism and arrogant ingratitude are commonly considered to be elements. The late twentieth century has been characterized as the age of narcissism because of its hedonistic self-centred focus
