Auditory‐motor adaptation is reduced in adults who stutter but not in children who stutter

Previous studies have shown that adults who stutter produce smaller corrective motor responses to compensate for unexpected auditory perturbations in comparison to adults who do not stutter, suggesting that stuttering may be associated with deficits in integration of auditory feedback for online speech monitoring. In this study, we examined whether stuttering is also associated with deficiencies in integrating and using discrepancies between expected and received auditory feedback to adaptively update motor programs for accurate speech production. Using a sensorimotor adaptation paradigm, we measured adaptive speech responses to auditory formant frequency perturbations in adults and children who stutter and their matched nonstuttering controls. We found that the magnitude of the speech adaptive response for children who stutter did not differ from that of fluent children. However, the adaptation magnitude of adults who stutter in response to auditory perturbation was significantly smaller than the adaptation magnitude of adults who do not stutter. Together these results indicate that stuttering is associated with deficits in integrating discrepancies between predicted and received auditory feedback to calibrate the speech production system in adults but not children. This auditory‐motor integration deficit thus appears to be a compensatory effect that develops over years of stuttering.     

Validity of the Short Form of the Parenting Stress Index for Fathers of Toddlers

We examined the psychometric properties of two scales of the parenting stress index-short form (PSI-SF) in a low-income sample of fathers of toddlers. The factor structure, reliability, and validity of the parental distress and parent–child dysfunctional interaction subscales were assessed for 696 fathers in a multi-site study of Early Head Start. Confirmatory factor analyses (CFA) compared the fit of the developer recommended two-factor scales with five-factor scales theoretically derived and supported with mothers. Our results suggested that two subscales from the PSI-SF were reliable and valid for this sample of racially diverse, low-income fathers of toddlers. However, these subscales capture multiple dimensions of parenting stress and results also supported the use of more narrowly defined aspects of parenting stress that included general distress, distress specifically related to parenting demands, problematic interactions of the father–toddler dyad, perceptions of the child, and parental perceptions of self as a parent. These unidimensional scales may prove useful in research and clinical activities by allowing researchers to elucidate the mechanisms through which stress impacts parenting and permitting clinicians information to develop more targeted interventions for young children and their families.     

Emotional display rules in Palestine: Ingroup/outgroup membership,status of interaction partner and gender

This study investigates emotional display rules within the Palestinian context, focusing on the seven basic emotions in a sample of 150 college students from the Gaza Strip and the West Bank. Overall, participants felt that it was more appropriate to express positive emotions (happiness and surprise) than negative powerful (anger, contempt and disgust) or negative powerless (fear and sadness) emotions. They also perceived it to be more appropriate to express positive and negative powerless emotions to ingroup than outgroup members and to express negative powerful emotions to lower status compared to higher status individuals. Gender differences were also found: men endorsed greater expression of both powerful and, surprisingly, powerless emotions than women, but only when interacting with outgroup members. Results are interpreted in terms of the cultural values of individualism–collectivism and power distance as well as cultural differences in emotional expressiveness between collectivistic societies. This study is one of the first to examine emotional display rules in an Arab population, thus expanding our current knowledge base.     

Associations between child physical abuse potential,observed maternal parenting,and young children's emotion regulation: Is participation in Early Head Start protective?

Clinicians working with Early Head Start (EHS) families consider family well-being and positive parent–child relationships as foundational to school readiness. Understanding the links between risk factors and these dimensions of family engagement can inform clinical decision-making, as risk assessments are used to tailoring program services. The current study examined the associations between high risk, or potential, for child physical abuse and both parenting quality and children's emotion regulation (ER) during toddlerhood; EHS participation was examined as a buffer. The sample included EHS-eligible mothers of infants (N = 80) drawn from one site of the EHS Research and Evaluation Project. Associations were tested between mothers’ potential for child physical abuse, measured during infancy, and observed maternal sensitivity, positive regard, harshness, and children's ER skills at child ages 1 and 2 years. Results indicated that high potential for child physical abuse was associated with lower positive regard at age 1 and lower ER skills at age 2. EHS participation operated as a buffer on each of these associations. Implications for screening for child physical abuse potential and the constructs it represents in clinical settings as well as how EHS can promote family engagement are discussed.     

Islam and Christianity between tolerance and acceptance

Basic to the understanding of Christianity and Islam as faith‐identities are their principles of ultimate power or authority. For both, ultimate power belongs to God alone, and human authority must reflect this divine power. In both a tension exists between these two powers which determined the course of their respective histories and interaction with one another. While in both religions tolerance is a fundamental principle based on the imperative of love and respect for human life and dignity, the Qur'an clearly advocates mutual acceptance and cooperation among the people of the Book: Jews, Christians and Muslims. This is evidenced in the term ahl al‐kitab, the family of the Book, which includes all the children of Abraham.     

Maltreated Children Use More Grammatical Negations

Many studies reveal a strong impact of childhood maltreatment on language development, mainly resulting in shorter utterances, less rich vocabulary, or a delay in grammatical complexity. However, different theories suggest the possibility for resilience—a positive adaptation to an otherwise adverse environment—in children who experienced childhood maltreatment. Here, we investigated different measures for language development in spontaneous speech, examining whether childhood maltreatment leads to a language deficit only or whether it can also result in differences in language use due to a possible adaptation to a toxic environment. We compared spontaneous speech during therapeutic peer-play sessions of 32 maltreated and 32 non-maltreated children from the same preschool and equivalent in gender, age (2 to 5 years), home neighborhood, ethnicity, and family income. Maltreatment status was reported by formal child protection reports, and corroborated by independent social service reports. We investigated general language sophistication (i.e., vocabulary, talkativeness, mean length of utterance), as well as grammatical development (i.e., use of plurals, tense, grammatical negations). We found that maltreated and non-maltreated children showed similar sophistication across all linguistic measures, except for the use of grammatical negations. Maltreated children used twice as many grammatical negations as non-maltreated children. The use of this highly complex grammatical structure shows an advanced linguistic skill, which shows that childhood maltreatment does not necessarily lead to a language deficit. The result might indicate the development of a negativity bias in the structure of spontaneous language due to an adaptation to their experiences.     

Nearest in amity: Christians in the Qur'an and contemporary exegetical tradition

This essay seeks to argue the following points: first, tafsir is an important means of understanding not only the Qur'an but also the social situation of the Muslim community in our own time. Second, the Qur'an presents a clearly pluralistic view of religion and culture which allows for religious diversity within the framework of faith in God and the last day and the performance of righteous deeds. Third, the Qur'anic verses discussed in this article illustrate this view; yet Qur'an commentators considered in this essay generally reject this Qur'anic worldview in favour of a much more rigid approach to other religions.     

The relationships between socially prescribed perfectionism,in‐group affect,negative urgency,and disordered eating in women

Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non‐specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female‐dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in‐group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (M_age = 25.12 years, SD = 3.08) using a cross‐sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female‐based SPP and disordered eating, while female‐based in‐group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in‐group (female) affect and DE may be better explained by SPP's link to DE.
