This study examined three- to seven-year-old children's abilities to recognize and label their own facial expressions of emotion. Each child posed four facial expressions (Happy, Sad, Angry, and Scared) which were photographed with a Polaroid camera. The child then selected each expression from the array of his/her own photos and labeled the facial expression of each photo. In addition to children's self-evaluations, the photo set's expressive content was evaluated by a panel of adult raters. Happy was the expression easiest for children to pose; Scared was the most difficult. Abilities involved in evaluating one's own facial expression (i.e., recognizing and labeling) appear not to be acquired simultaneously with the ability to pose the expression. Not all children conformed to adult standards in evaluating their own expressions. Nearly one-fifth of the children studied exhibited evidence of an idiosyncratic expressive scheme for at least one of their facial expressions.  相似文献

This study examined whether parental control differentially predicted children's effortful control and adjustment depending on children's levels of executive control and delay ability. Using longitudinal data, the study included 241 preschool-age children and their mothers. Fifty-seven percent of the sample was lower income and included 64% White, 10% Latino/Hispanic, 9% Black, 3% Asian-American, 2% Native or American Indian, and 12% multiple racial/ethnic backgrounds. Interactions between aspects of parental and child control at 3-years-old were tested as predictors of mother-reported child effortful control at 4.5 years and teacher-reported adjustment at 5.5 years. Children's early levels of executive control and delay ability moderated the relations of some forms of parental control with child outcomes, although several hypothesized interactions were nonsignificant. Low parental autonomy respect predicted higher externalizing for children initially high in executive control but predicted lower externalizing for children initially low in executive control. Conversely, high autonomy respect predicted higher impulsivity for children low in delay ability but higher social competence for children high in delay ability. Finally, low maternal negative control predicted higher internalizing for children low in delay ability, whereas it predicted higher internalizing for children high in delay ability. These findings suggest that in some cases the type and degree of parental control should match a child's level of effortful control to support their social, emotional, and behavioral adjustment optimally.  相似文献

Limited research has directly sought the input of parents involved in the child protection system during pregnancy and with their infants. As the focus of these policies and practices, parents have a unique and important insight not available to others, so it is vital to obtain their input. As part of a larger Australian study, qualitative interviews were undertaken with 13 parents asking about their views and experiences. Parents predominantly became involved with child protection services during pregnancy through a prenatal report. Parents who previously had their newborn removed from their care described it as sudden and unexpected, leaving them distressed and unsupported post-removal, with a growing list of requirements for them to see their baby or for restoration to be considered. Domestic violence was a particular issue of concern for some mothers who expressed distress that their partners, perpetrators of violence, were allowed access to their infant with fewer requirements than for them. Improvements recommended by the parents included greater communication and preparation for the removal, better recognition of improvements in their situations and increased supports to be provided to parents both pre- and post-removal. Parental experiences provide an important guide to improving child protection practice with these families.  相似文献

A Scottish national child protection audit has shown that practitioners can have differing understanding of the term ‘disability’ and are variable in their own recording of disabilities. It was apparent from the audit that disability was more likely to be recorded for older children than those under five. The audit found that an abuse allegation is less likely to be substantiated for disabled children by a Child Protection Medical Examination. For disabled children in our sample, there was a ‘substantiation of abuse rate’ of 33%, which was less than the 56% rate for non-disabled children. The differences in rates encourage us to consider what is an appropriate response when disabled children may have experienced harm and abuse. The audit highlights the vulnerability of disabled children to abuse and indicates the need to equip practitioners with the skills, competencies and confidence to engage with and support this vulnerable group.  相似文献

Infants have the highest rate of admission into out-of-home care in Australia, with rising rates of entry to care occurring around the world. Our previous research identified children who entered care as infants as having high levels of developmental vulnerability. The objective of this study was to determine the child protection and developmental trajectories of children who entered care as infants and whether meeting developmental needs through service provision improves trajectories and outcomes for these children. This is a prospective cohort study using three waves (2011–2016) of survey data from the New South Wales Pathways of Care Longitudinal Study which includes standardised assessments (Age and Stages Questionnaire, Brief Infant Toddler Social Emotional Assessment and the Child Behaviour Checklist), as well as linked administrative child protection and health data. Our findings suggest that children who entered care as infants predominantly remained in the care system and had a high level of developmental vulnerability as infants. A large group had positive physical and cognitive developmental trajectories with service provision increasing over time; however, early service provision is needed. Another group was identified as having early social–emotional concerns and displaying worsening social–emotional trajectories. Intervention for this group is an important priority to reduce risk of ongoing poor mental health outcomes.  相似文献

In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios.  相似文献

La gouvernance privée telle qu'elle découle des différentes initiatives prises par les multinationales pour promouvoir le respect de normes sociales et l'égalité hommes‐femmes a eu peu d'effet sur les discriminations fondées sur le genre dans les chaînes d'approvisionnement mondiales. Les auteures soulignent l'intérêt des Principes directeurs des Nations Unies relatifs aux entreprises et aux droits de l'homme en la matière, estimant qu'il est indispensable de recourir à une gouvernance «stratifiée» associant public, privé et acteurs sociaux pour lutter contre cette discrimination et intégrer le souci de l'égalité des sexes dans l'exercice de la diligence raisonnable exigée en matière de droits de l'homme.  相似文献

Although the field of social work is grounded in social justice, the social work educational experience, including classrooms, may not live up to this value, especially for lesbian, gay, bisexual, transgender, and queer (LGBTQ) students. Using a qualitative phenomenological approach, this study examined the experiences of harmful discourse in social work classrooms for LGBTQ students. Findings indicate that students experienced being misgendered, tokenized, and erased through cis-/heteronormative language and classroom teachings. Although social work is guided by frameworks of social justice, microaggressions and discrimination may be vaguely glossed over, if addressed at all. This study highlights the gap between the values social work teaches and how social work education is delivered.  相似文献

In order to make feedback as effective as possible, it is important to understand its function in the three-term contingency (TTC) and the impact of various factors involved in delivering feedback. Timing of feedback is one factor that can affect the impact of feedback on learner’s behavior. An analysis of timing of feeback may help us getting closer to better understanding how feedback functions in the TTC. The purpose of this study was to evaluate the effects of feedback at different temporal locations. Specifically, feedback was provided either immediately (a) after a teaching session or (b) before the following teaching session, on teaching performance of undergraduate psychology students. The results indicated that feedback provided before the teaching session was more effective in improving teaching skills than feedback that was provided after the session. These findings suggest that feedback may function primarily as an antecedent to future performance and not necessarily as a consequence for past performance. However, the behavioral mechanism that explains these results is not yet clear. Future studies should investigate this further by manipulating the content of feedback prior to the teaching performance.  相似文献
