The Development of Rational Imitation in 9‐ and 12‐Month‐Old Infants

Studies on rational imitation have provided evidence for the fact that infants as young as 12 months of age engage in rational imitation. However, the developmental onset of this ability is unclear. In this study, we investigated whether 9‐ and 12‐month‐olds detect voluntary and implicit as well as nonvoluntary and explicit constraints in the head touch task. Three groups of infants watched video sequences, which displayed a person illuminating a lamp using the head. The hands of the model were either free, occupied by voluntarily holding a blanket, or nonvoluntarily restrained by being tied to the table. An additional control group of infants watched the model turning on the lamp by using the hand. Given that the majority of infants imitated the head touch when the model's hands were free, there was evidence for rational imitation in comparison to the condition in which the model's hands were tied to the table, but not in comparison to the condition in which the hands were occupied by holding a blanket. Nine‐month‐olds showed no differences in their behavior according to the condition. These findings clarify the onset of rational imitation by showing that 12‐month‐olds (but not 9‐month‐olds) take into account a situational constraint only when the constraint is nonvoluntary and explicit.     

Reactions of students to different settings of field experience

The study assessed Israeli students’ emotional–experiential reaction and attitude to different client populations, following a week-long experience in one of five social services settings. The study provides preliminary findings regarding the implications of first year students’ experience on their emphatic skills, a subject that generally has not received adequate scholarly attention. Using a purpose-built, self-administered questionnaire, we found students’ emotional–experiential response to their experience differed by the setting in which they were placed, being lowest in the Bedouin oriented services, intermediate among those placed in juvenile correction services, and highest in mental health, adult and child disability services. Responses were independent of all other explanatory variables, including sex, cognitive ability, previous training experience and perceptual shifts concerning the population served. We discuss possible reasons for these differences.

     

Evidence-based practice: a critical reflection

This article employs the process of critical reflection to uncover and challenge the hegemonic assumptions of evidence-based practice (EBP). The critical reflection process results in a re-conceptualisation of best practices that, while still honouring empirical research, is less hierarchical and more inclusive of a broad spectrum of interests than traditional EBP. Multidimensional Evidence-Based Practice (MEBP) validates consumer wisdom, professional experience, and qualitative research as equal partners to quantitative research in determining current state-of-the art best practices. Furthermore, MEBP incorporates a value-critical analysis of those best practices that can lead to improvements and innovations, so that ‘best practices’ becomes a dynamic rather than a static construct.     

Relation Between Maternal Contingent Responsiveness and Infant Social Expectations

This study investigated the relation between maternal contingent responsiveness and 4‐ and 5‐month‐old infants' (N = 64) social expectation behavior in a still‐face procedure. Mothers were asked to interact with their infants for 2 min (interactive phase), remain still‐faced for 1 min (still‐face phase), and resume interaction for 2 min. Mother and infant behavior was assessed for the frequency of infant and mother smiles, mother smiles that were contingent to infant smiles and infant smiles were contingent to mother smiles during the interactive phase, and infant social bids to mother during the still‐face phase. Hierarchical regression showed that mother contingent smiles during the interactive phase accounted for unique variance in infant social bids during the still‐face phase beyond that accounted for by the frequency of mother and infant smiles during the interactive phase. These results support the view that young infants' social expectations and sense of self‐efficacy are formed within their interactions with their caregivers.     

Infants' Response to Maternal Mirroring in the Still Face and Replay Tasks

Infants' response to maternal mirroring was investigated in 4‐month‐old infants. Mother–infant dyads participated in the still face and replay tasks. Infants were grouped by those whose mothers did and did not mirror their behavior in the interactive phases of the tasks. In the still face task, infants with maternal mirroring showed more attention, smiling, and positive vocalizations across the phases, although both groups of infants demonstrated the still‐face effect with attention and smiling. Infants' social bidding to the mother during the still‐face phase correlated with mothers' mirroring behavior. In the replay task, infants with maternal mirroring demonstrated carryover effects with smiling; infants without maternal mirroring showed no awareness of change in their mothers' behavior. In both the still face and replay tasks, infants with maternal mirroring were more engaged with their mothers. Results suggest that maternal mirroring of infants' behavior affects infants' detection of, and response to, reciprocal interaction.     

Low‐Income Mothers’ Private Safety Nets and Children’s Socioemotional Well‐Being

Using longitudinal data from the Fragile Families and Child Well‐being Study (N = 1,162) and the National Evaluation of Welfare‐to‐Work Strategies (N = 1,308), we estimate associations between material and instrumental support available to low‐income mothers and young children’s socioemotional well‐being. In multivariate OLS models, we find mothers’ available support is negatively associated with children’s behavior problems and positively associated with prosocial behavior in both data sets; associations between available support and children’s internalizing and prosocial behaviors attenuate but remain robust in residualized change models. Overall, results support the hypothesis that the availability of a private safety net is positively associated with children’s socioemotional adjustment.     

Climate,migration, and the local food security context: introducing Terra Populus

Studies investigating the connection between environmental factors and migration are difficult to execute because they require the integration of microdata and spatial information. In this article, we introduce the novel, publically available data extraction system Terra Populus (TerraPop), which was designed to facilitate population–environment studies. We showcase the use of TerraPop by exploring variations in the climate–migration association in Burkina Faso and Senegal based on differences in the local food security context. Food security was approximated using anthropometric indicators of child stunting and wasting derived from Demographic and Health Surveys and linked to the TerraPop extract of climate and migration information. We find that an increase in heat waves was associated with a decrease in international migration from Burkina Faso, while excessive precipitation increased international moves from Senegal. Significant interactions reveal that the adverse effects of heat waves and droughts are strongly amplified in highly food insecure Senegalese departments.     

Relationship Between Household Food Poverty and Vulnerability to Food Poverty: Evidence from Nigeria

Poverty and vulnerability to poverty are major challenges facing developing countries and have attracted the attention of development economists and policy analysts in recent years. This study examined the relationship between household food poverty and vulnerability to food poverty in Nigeria based on data from Nigeria Living Standard Survey (NLSS) (2004) obtained from the National Bureau of Statistics. A least-cost technique associated with the food-energy-intake approach was used to compute zone-specific food poverty lines based on the food baskets common to each geo-political zone; the Foster–Greer–Thorbecke (FGT) poverty index was used in computing food poverty incidence; the three-step feasible generalised least squares (3FGLS) procedure was used in estimating the magnitude of vulnerability to food poverty; cross tabulation and Pearson’s product moment correlation coefficient were utilised for the purpose of analysing the association between household food poverty and vulnerability to food poverty. The food poverty incidence was 50.23 % while the vulnerability to food poverty incidence was 61.68 % and the vulnerability to food poverty/food poverty ratio was 1.228. The food poor were more vulnerable to food poverty than the non food poor. There was significant positive correlation between food poverty incidence and vulnerability to food poverty incidence even though the correlation was not very strong. Thus, policies and programmes that will optimally reduce food poverty and vulnerability to food poverty should be adopted in Nigeria; these should be targeted more on the food poor. This is a major way to break the yoke of underdevelopment in Nigeria.     

Improved randomized response in additive scrambling models

Randomized response models deal with stigmatizing variables appearing in health surveys. Additive and subtractive scrambling in split sample and double response yield unbiased mean and sensitivity estimators of high precision. The split sample method is protective of privacy. The double response method is as protective only conditionally. To achieve the maximum efficiency, the scrambling variables must be similar to each other and the probability of obtaining a true response must be as large as possible. The randomized response procedures yield more efficient estimates of the average total number of classes missed by university students.
