Co‐development of child‐mother gestures over the second and the third years

This study looks at whether there is a relationship between mother and infant gesture production. Specifically, it addresses the extent of articulation in the maternal gesture repertoire and how closely it supports the infant production of gestures. Eight Spanish mothers and their 1‐ and 2‐year‐old babies were studied during 1 year of observations. Maternal and child verbal production, gestures and actions were recorded at their homes on five occasions while performing daily routines. Results indicated that mother and child deictic gestures (pointing and instrumental) and representational gestures (symbolic and social) were very similar at each age group and did not decline across groups. Overall, deictic gestures were more frequent than representational gestures. Maternal adaptation to developmental changes is specific for gesturing but not for acting. Maternal and child speech were related positively to mother and child pointing and representational gestures, and negatively to mother and child instrumental gestures. Mother and child instrumental gestures were positively related to action production, after maternal and child speech was partialled out. Thus, language plays an important role for dyadic communicative activities (gesture–gesture relations) but not for dyadic motor activities (gesture–action relations). Finally, a comparison of the growth curves across sessions showed a closer correspondence for mother–child deictic gestures than for representational gestures. Overall, the results point to the existence of an articulated maternal gesture input that closely supports the child gesture production. Copyright © 2006 John Wiley & Sons, Ltd.     

Sensitivity to amplitude envelope rise time in infancy and vocabulary development at 3 years: A significant relationship

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination of amplitude envelope rise times could be expected to relate to individual differences in language acquisition. A group of 50 infants taking part in a longitudinal study contributed rise time discrimination thresholds when aged 7 and 10 months, and their vocabulary development was measured at 3 years. Experimental measures of phonological sensitivity were also administered at 3 years. Linear mixed effect models taking rise time sensitivity as the dependent variable, and controlling for non‐verbal IQ, showed significant predictive effects for vocabulary at 3 years, but not for the phonological sensitivity measures. The significant longitudinal relationship between amplitude envelope rise time discrimination and vocabulary development suggests that early rise time discrimination abilities have an impact on speech processing by infants.     

Hand Switching Costs are not Uniform Across Response Components

We investigated the extent to which a complex finger sequence impacts on hand switching costs in a sequential action. Response component latencies (premotor, motor, and movement) were compared in no-switch (same finger performed the action of pressing and reaching) and switch conditions (pressing with one finger and completing the reaching action with the homologous finger from the other hand). Results showed that the switch condition presented longer latency for premotor and movement components. For the motor component, however, switch condition was faster. This expands the previous literature investigating switching costs using simple finger movements in more complex tasks. A mechanical explanation of the interplay between response subcomponents is provided to explain the inversion of response pattern for the motor component.

The Anatomy of a Philosophical Hoax

This article reflects upon the state of the philosophical profession vis‐à‐vis a close reading of the hoax perpetrated against the International Journal of Badiou Studies in 2016. This hoax is not a subversive act of disciplinary criticism (as the hoaxers contend). Rather, it is a poorly disguised attempt to enforce a partisan and myopic conception of philosophy and to delegitimize an entire subfield of philosophical production—namely, continental philosophy. The hoax is symptomatic of a deeper problem that plagues the profession today: the willingness exhibited by many philosophers to police the boundaries of the discipline by engaging in what we call “acts of force.” The prevalence of acts of force demonstrates that professional philosophy is shaped not only by the giving and taking of reasons but also by shopworn disciplinary tribalisms (for example, continental versus analytic) and asymmetrical power relations involving agents with unequal amounts of social, professional, and philosophical capital.     

Psychometric properties of the cyberbullying triangulation questionnaire: A prevalence analysis through seven roles

This study explores the psychometric properties of the Cyberbullying Triangulation Questionnaire (CTQ), which measures and triangulates the roles of cybervictimization, cyberaggression, and cyberbystanding. The study sample was composed of 5,036 Spanish students with a mean age of 14.19 years (SD = ±1.7; range = 10–23 years). Confirmatory factor analysis of the three correlated‐factor model yielded a high goodness of fit. Reliability as measured by Omega coefficients was adequate (>0.94). The measurement model was invariant for the two age groups (10–14 years and 15–23 years). Cybervictimization and cyberaggression correlated with offline victimization and aggression (r = 0.49; p < 0.001; r = 0.57; p < 0.001, respectively). The results show that the most prevalent cyberbystanding subrole was that of the Defender of the Victim (54.6%), and that cyberaggression and cyberbystanding were more prevalent among male adolescents (p < 0.001). The lack of parental control over children's use of the mobile phone was associated with cyberaggression (p < 0.001).     

Minority Stress,Activism, and Health in the Context of Economic Precarity: Results from a National Participatory Action Survey of Lesbian,Gay, Bisexual,Transgender, Queer,and Gender Non‐Conforming Youth

Lesbian, gay, bisexual, transgender, queer, and gender non‐conforming (LGBTQ & GNC) youth experience more economic hardship and social stress than their heterosexual and cisgender peers. However, the ways that LGBTQ & GNC youth resist these damaging social factors and the corresponding implications for their health have not been addressed. Data were analyzed from a national participatory survey of LGBTQ & GNC youth ages 14–24 (N = 5,860) living in the United States. Structural equation models indicated that economic precarity was associated with experiences of health problems. This association was mediated by the negative influence of minority stress on health as well as by activism, which had a positive association with health. Findings suggest that minority stress explanations of health inequalities among LGBTQ & GNC youth can benefit from including a focus on economic precarity; both in terms of its deleterious impact on health and its potential to provoke resistance to structural oppression in the form of activism.

Mediterranean diet and wellbeing: evidence from a nationwide survey

Objective: Although there is some evidence of the association between specific food groups, such as plant foods, and subjective wellbeing, this is the first study to assess the relationship between adherence to the Mediterranean dietary pattern and subjective wellbeing. Design: Data were collected in 2014–2015, within the Edad con Salud project, a follow-up study of a multistage clustered survey on a representative sample of the population of Spain. The final sample comprised 2397 individuals with ages ranging from 21 to 101 years. Main outcome measures: Experienced wellbeing (positive and negative affect) was measured using the Day Reconstruction Method, and evaluative wellbeing was assessed with the Cantril Self-Anchoring Striving Scale. Results: A higher adherence to the Mediterranean diet showed a small but statistically significant inverse relationship with negative affect (β?=??0.076, p=.001), and direct with evaluative wellbeing (β?=?0.053, p=.015), whereas it was not related to positive affect. Several components of the Mediterranean diet were independently associated with wellbeing. Conclusion: The results suggest that adherence to a dietary pattern such as the Mediterranean diet, and not only the isolated consumption of its components, is associated with a better subjective wellbeing.
