Family Risk and Externalizing Problems in Chilean Children: Mediation by Harsh Parenting and Emotional Support

Latent class analysis and multigroup mediation were used with 8,860 families in Chile to identify risk groups varying in socioeconomic status, family structure, and maternal depression, to determine whether profiles differed in children’s development of externalizing problems (EP) from 35 to 61 months, and maternal parenting that predicted EP. Four groups were identified: one no-risk profile and three risk profiles, impoverished and undereducated, depressed and impoverished, and father-absent and impoverished. All classes differed in EP. Maternal emotional support and harsh parenting were differentially associated with the development of EP across the three risk groups, relative to the low-risk group. Thus, specific constellations of adversities differentially predicted children’s EP and socialization processes mediating links between risk and EP. Implications are discussed.     

‘Family comes in all forms,blood or not’: disrupting dominant narratives around the patriarchal nuclear family

ABSTRACT

After nearly 25 years of democracy, lives of young South Africans are still profoundly shaped by the legacies of apartheid. This paper considers how these differences are produced, maintained and disrupted through an exploration of changing narratives developed by a small group of South African pre-service teachers, with a particular focus on the narratives developed around discourses of fatherhood generally and absent fathers in particular. We draw on interviews conducted with three students in which we discussed their digital stories and literature reviews. In this paper, we draw attention to the limitations of digital storytelling and the risks such autobiographical storytelling presents of perpetuating dominant narratives that maintain and reproduce historical inequalities. At the same time, in highlighting ways in which this risk might be confronted, the paper also aims to show the possibilities in which these dominant narratives may be challenged.     

Arithmetic education and learning disabilities in Italy

In the first part of this article, we briefly present the context of mathematics education in Italy and its specific programs, teaching and assessment methods, use of psychological concepts, and policies in favor of pupils with difficulties. We illustrate the importance and the role of mathematics teachers' associations. In the second part, we focus more directly on the issue of arithmetic learning and learning disabilities in Italy. Despite the absence of a specific strong tradition in the field, new perspectives regarding mathematics education are evident in Italy. The preparation of new assessment tools has proceeded together with an effort toward the identification of subtypes of arithmetic learning disabilities. A basic distinction has been made between difficulties in number processing/calculation and problem-solving tasks. Within the area of calculation, a finer distinction between numerical knowledge, speed, and accuracy seems critical, but a more articulated differentiation of subcomponents relying on modern cognitive-neuropsychological models can be used also.     

Making Sense of Number Words and Arabic Digits: Does Order Count More?

The ability to choose the larger between two numbers reflects a mature understanding of the magnitude associated with numerical symbols. The present study explores how the knowledge of the number sequence and memory capacity (verbal and visuospatial) relate to number comparison skills while controlling for cardinal knowledge. Preschool children’s (N = 140, M_{age-in-months} = 58.9, range = 41–75) knowledge of the directional property of the counting list as well as the spatial mapping of digits on the visual line were assessed. The ability to order digits on the visual line mediated the relation between memory capacity and number comparison skills while controlling for cardinal knowledge. Beyond cardinality, the knowledge of the (spatial) order of numbers marks the understanding of the magnitude associated with numbers.     

Empowering visuo-spatial ability in primary school: results from a follow-up study

The current study was primarily aimed at verifying the effect of a combined computer-assisted and pencil-and-paper training that was developed to empower visuo-spatial abilities in primary school pupils. One hundred and twenty third grade (mean average: eight years old) and fourth grade (mean age: nine years old) students attending several Italian primary schools were presented with several tests of the Primary Mental Abilities (PMA) battery by Thurstone and Thurstone. Of these, 64 children underwent the training “Recovery in visuo-spatial abilities” developed by Fastame and Antonini for 15 weekly sessions. The remaining students were assigned to the control group. Post-test scores and a follow-up assessment after six months by the end of the training highlight the positive impact of the intervention in enhancing visuo-spatial abilities.     

Development of gender constancy and selective attention to same-sex models.

4 developmental levels of gender constancy were identified in 55 preschool-age children on the basis of a reproducible Guttman scale of answers to sets of questions pertaining to gender identity, gender stability over time, and gender consistency across situations. Children's developmental level of gender constancy was predictive of the amount and the proportion of time they attended to an adult male and an adult female film model. As boys developed gender constancy, their relative preference for watching the male model increased significantly; as girls developed gender constancy, their relative preference for watching the female model increased, though not significantly. At the more advanced levels of gender constancy, boys watched the male model more than did girls. It was suggested that same-sex social learning may develop as a function of children's cognitive understanding of gender as an identifiable, stable and consistent human attribute.     

Second-order conditioning: Different outcomes in fear and eyelid conditioning

Second-order conditioning has been frequently observed with the fear response but not with the eyelid response. The present experiments manipulated the temporal relationship between the second-order and first-order stimulus on second-order conditioning trials. Our results indicated that a trace second-order procedure is not effective with either response system. Second-order fear conditioning was most prominent when the second-order CS terminated at the onset of the first-order CS. This arrangement, however, did not produce second-order eyelid CRs. In eyelid conditioning, the second-order CS appears to inhibit responding to the first-order CS which immediately follows it.

Effects of inspiratory muscle training in professional women football players: a randomized sham-controlled trial

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players.
