Do older individuals have difficulty processing motion or excluding noise? Implications for safe driving

This study aimed to determine if difficulties extracting signal from noise explained poorer coherent motion thresholds in older individuals, particularly women. In four experimental conditions the contrast of the signal and noise dots used in a random dot kinematogram was manipulated. Coherence thresholds were highest when the signal dots were of a lower contrast than the noise dots and lowest when the signal dots were of a higher contrast than the noise dots. In all conditions the older group had higher coherence thresholds than the younger group, and women had higher thresholds than men. Significant correlations were found between coherence thresholds and self-reported driving difficulties in conditions in which the signal dots had to be extracted from noise only. The results indicate that older individuals have difficulties extracting signal from noise in cluttered visual environments. The implications for safe driving are discussed.     

Welcome to “the Rock”: Service Providers’ Views on Newcomer Youth Integration in Newfoundland and Labrador

This study investigates the needs of newcomer youth in Newfoundland and Labrador, and the services provided to them in the provincial capital, St. John’s, through the lens of service providers. We employ Bronfenbrenner’s bioecological model (1999, 2005) as the conceptual framework to explore how various ecological systems interact with one another to influence the development of newcomer youth. Data were drawn from 33 semi-structured interviews with personnel in various immigrant and refugee support agencies, medical and counseling units, municipal recreational offices, and educational programs, as well as ten observations of their programs. Our findings indicate that the current services and programs provide effective support in a number of areas. However, closer collaboration can be established between schools and community organizations, among different service agencies, and involving the business community. Service gaps identified include a lack of transportation to and from school, insufficient academic bridging programs, and no career counseling catering to newcomer students. We argue that service agencies should consider shifting some of their programs to the newcomer youth’s microsystems of school and family, and that the provincial educational authorities need to look into the transportation issue that infringes upon the rights of these students to appropriate school instruction.

Reading Anxiety: An Early Affective Impediment to Children’s Success in Reading

Learning to read is a critical but often challenging academic task for young children. In the current study, we explore the relation between children’s reading affect-–particularly anxiety-–and reading achievement in the early years of reading acquisition. We hypothesized that reading anxiety would relate to reading achievement across the school year and that boys and girls might show differential patterns in the relation between reading anxiety and achievement due to the common stereotype that boys underperform in reading. A sample of first and second grade students completed measures of reading anxiety, positive reading affect, math achievement, and reading achievement in the fall and spring. Results show that reading anxiety and reading achievement share a bi-directional relation in which fall reading anxiety predicts spring reading achievement and vice versa. Furthermore, the pattern of relation between reading anxiety and achievement differs by gender: boys appear more susceptible to the reciprocal damaging effects of reading anxiety on reading achievement across the school year. Finally, reading achievement shares a stronger relation with reading anxiety than with positive reading affect, perhaps because of the phenomenon in which negative relative to positive experiences have a greater psychological impact.     

Social Validity of a Training and Coaching Program for Parents of Children With Autism Spectrum Disorder on a Waiting List for Early Behavioral Intervention

Due to limited public resources, many children with autism spectrum disorder and their families must wait several months, if not years, to access early behavioral intervention (EBI) services. Service providers must thus develop alternative support models to assist families placed on waiting lists. The present study assessed the social validity of one such initiative, a training and coaching program for parents whose children had been put on a waiting list for EBI services. This program consisted of group training sessions on strategies to cope with their child’s disorder based on applied behavioral analysis and on one-hour, weekly follow-up meetings to support parents’ interventions with their child over the course of 12 months. Social validity was assessed through parental satisfaction with this program and their perception of its effects on themselves, the family, the child, and parental stress. The 94 participants were generally satisfied with the program overall, although they wished for more frequent and intensive interventions. They reported that the program had positive effects on their psychological well-being, their family’s quality of life, and their child’s behavior. However, parenting stress levels were found to have increased over the 12-month period. These results demonstrate that training and individually supporting parents can be beneficial for families of children with ASD who cannot have access to early behavioral intervention immediately upon receiving a diagnosis. Importantly, however, these lower-cost, parent-focused programs cannot be considered a substitute for more intensive and children-driven services.     

Multidimensional assessment of family involvement among urban elementary students

Family involvement in children's education is fundamental for academic success. This study extended the research on the Family Involvement Questionnaire for Early Childhood (FIQ-EC) by further developing the measure and testing its use with low-income urban elementary students. Exploratory and confirmatory factor analyses affirmed three salient and reliable family involvement dimensions for a large sample of urban first- through fifth-grade students: Home-based Involvement, School-based Involvement, and Home–School Communication. Multivariate analyses demonstrated the significance of caregiver educational background, family characteristics, and child gender to involvement dimensions. Caregiver age or children's grade level did not significantly relate to family involvement dimensions. This study contributes to evidence for a multidimensional understanding of family involvement.     

Infants' meaning-making and the development of mental health problems

We argue that infant meaning-making processes are a central mechanism governing both typical and pathological outcomes. Infants, as open dynamic systems, must constantly garner information to increase their complexity and coherence. They fulfill this demand by making nonverbal "meaning"-affects, movements, representations-about themselves in relation to the world and themselves into a "biopsychosocial state of consciousness," which shapes their ongoing engagement with the world. We focus on the operation of the infant-adult communication system, a dyadic, mutually regulated system that scaffolds infants' engagement with the world of people, things, and themselves, and consequently their meaning-making. We argue that infant mental health problems emerge when the meanings infants make in the moment, which increase their complexity and coherence and may be adaptive in the short run, selectively limit their subsequent engagement with the world and, in turn, the growth of their state of consciousness in the long run. When chronic and iterative, these altered meanings can interfere with infants' successful development and heighten their vulnerability to pathological outcomes. Cultural variations in meaning-making and implications for clinical practice are discussed.     

EFFECTS OF MATERNAL DEPRESSION AND PANIC DISORDER ON MOTHER-INFANT INTERACTIVE BEHAVIOR IN THE FACE-TO-FACE STILL-FACE PARADIGM

The present study evaluated the interactive behavior of three groups of mothers and their 3-month-old infants in the Face-to-Face Still-Face paradigm. The mothers had either a clinical diagnosis of major depressive disorder (MDD, n = 33) with no comorbidity, a clinical diagnosis of panic disorder (PD, n = 13) with no comorbidity, or no clinical diagnosis (n = 48). The sample was selected to be at otherwise low social and medical risk, and all mothers with PD or MDD were in treatment. The findings indicated that (a) infants of mothers with PD or MDD displayed the traditional still-face and reunion effects described in previous research with nonclinical samples; (b) the 3-month-old infants in this study showed similar, but not identical, gender effects to those described for older infants; and (c) there were no patterns of maternal or infant interactive behavior that were unique to the PD, MDD, or control groups. These results are discussed in light of mothers' risk status, receipt of treatment, severity of illness, and comorbidity of PD and MDD.
