Fear potentiation of the acoustic startle reflex using noises of various spectral frequencies as conditioned stimuli

The effectiveness of noise of various intensities and frequencies in modulating the amplitude of the acoustic startle reflex was evaluated, as a preliminary test of the capacity of these noises to produce consistent and reliable fear-potentiated startle in rats. It was determined that bands of noise containing high frequencies (greater than 10 kHz) tend to unconditionally reduce acoustic startle responses, probably by masking the high-frequency startle-eliciting stimulus. Noise containing high frequencies produced reliable fear-potentiated startle only when its estimated unconditioned startle suppression was subtracted from the enhancement obtained after pairing it with footshocks. Noises devoid of high frequencies produced modest-unconditioned startle enhancements and the most robust and reliable fear-potentiated startle when they were paired with footshocks. A nonmonotonic relationship between training shock intensity and the level of fear-potentiated startle was also exhibited when a low-frequency noise was used as a conditioned stimulus, a finding consistent with previous studies in which a visual stimulus was used. Finally, a differential Pavlovian conditioning procedure indicated that rats could readily discriminate between two different low-frequency bands of noise. The outcome of these experiments indicates that it is easier to employ low-frequency bands of noise to obtain auditory fear-potentiated startle with high-frequency startle-eliciting stimuli.     

Deaf college students' comprehension of relational language in arithmetic compare problems

In this study of deaf college students' performance solving compare word problems, relational statements were either consistent or inconsistent with the arithmetic operation required for the solutions. The results support the consistency hypothesis Lewis and Mayer (1987) proposed based on research with hearing students. That is, deaf students were more likely to miscomprehend a relational statement and commit a reversal error when the required arithmetic operation was inconsistent with the statement's relational term (e.g., having to add when the relational term was less than). Also, the reversal error effect with inconsistent word problems was magnified when the relational statement was a marked term (e.g., a negative adjective such as less than) rather than an unmarked term (e.g., a positive adjective such as more than). Reading ability levels of deaf students influenced their performance in a number of ways. As predicted, there was a decrease in goal-monitoring errors, multiple errors, and the number of problems left blank as the reading levels of students increased. Contrary to expectations, higher reading skills did not affect the frequency of reversal errors.     

Using Early Learning Standards to Provide High-Quality Education for All Children: The Early Learning Guidelines Toolkit

Today with the rise in the number of 3- to 6-year-old children enrolled in center-based early childhood programs, and a focus on program quality, it becomes imperative for educators to have a better understanding of the role research plays in establishing high-quality programs as these programs provide much of the foundation that supports early learning and development (Child Trends, 2014). Although psychology, and the role of child development research in particular, has always been integral to the field of early childhood education beginning with the seminal works of Piaget, Bronfenbrenner, Bruner, and others (Lickona,1971), the field had never fully embraced the use of research to inform practice, until the 1990s. This had been, in part, because the field of early childhood education originally viewed itself as a field of practitioners that provided for the everyday care and needs of young children, whereas it viewed child development researchers as scientists who paid little attention to the practical needs of classroom teaching (Takanishi, 1981 Takanishi, R. (1981). Early childhood education and research: The changing relationship. Theory into Practice, 20, 86–92.[Taylor & Francis Online] , [Google Scholar]). Although, today, there is no longer this ideological divide between the two areas, with the child development research being used to inform educational practice and policy (Center for the Developing Child, 2007), nevertheless there still remains a gap in the ability of educators to effectively implement evidence-based practices. Given the increased focus on providing young children with access to high-quality education, and the need for teachers to implement evidence-based practices the present paper attempts to bridge the gap by providing a brief overview of the science of early childhood development, its importance for development of early learning standards, and an overview of the Early Learning Toolkit which was developed to provide early learning educators guidance and resources to support the implementation of early learning standards within their own states as well as well across the nation. The goal of this article is to bridge theory and practice in early childhood education.     

Using student norms to create positive learning environments

Ever since brash young students goaded one another to race chariots through the streets of the ancient world, elders have tried to understand and harness the energy of late adolescent normative group behavior. John Braxton and Timothy Caboni introduce a perspective and survey instrument that may help today's educators do just that.

Secondary school educational practitioners’ experiences of school attendance problems and interventions to address them: a qualitative study

School attendance problems are associated with a range of adverse consequences, and educational practitioners play a role in identifying and responding to attendance problems. This qualitative study explored educational practitioners’ experiences of working with students with attendance problems and interventions to address them. Focus groups were conducted with sixteen practitioners across three secondary schools. Data were analysed using thematic analysis. Attendance problems were considered resource-intensive and emotionally challenging. Practitioners expressed difficulty understanding causes, although individual/family factors were emphasised over school factors. A range of interventions were described, including adaptations to school context and providing emotional support. Views on punitive approaches were mixed. Individualised interventions implemented at the first sign of problems, and a team approach, were considered important. Findings highlight the important role of educational practitioners in identifying attendance problems and implementing interventions. Recommendations include early intervention, team-work, and emotional support for students with, and staff responding to, attendance problems.
