Covariation in conditioned response strength between stimuli trained in compound

Conditioned lick suppression by water-deprived rats was used to elaborate on recent evidence that the attenuated conditioned response elicited by an overshadowed stimulus may be enhanced by extinction of the overshadowing stimulus with which it had been trained in simultaneous compound. Using a modified serial stimulus arrangement in which a light coexisted with the last half of a tone that terminated with footshock, it was found in Experiment 1 that the tone overshadowed the light. Extinction of the tone-shock association resulted in a virtually complete recovery of the response to the overshadowed light. Using this serial overshadowing procedure, the possibility that the strength of a conditioned response to an element trained in compound covaries as a function of the strength of the response to the other element was tested in Experiment 2. Following overshadowing training similar to that of Experiment 1, independent reinforcement of the overshadowed light, that is, associative inflation, was found to have no deleterious effect on the response to the overshadowing tone. This suggests that the effects of postconditioning extinction and inflation of one element do not have symmetrical effects upon responding to the other element. The results of Experiment 2 were replicated in Experiment 3 using a simultaneous compound stimulus as opposed to the serial compound of the previous studies. These results are discussed in terms of various associative and cognitive models of learning and performance.     

Serving two masters: how vocational educators experience marketisation reforms

Contemporary education reforms that draw ideas from the political and economic fields are said to be altering the nature of vocational education. While there are substantial policy studies on the effects of marketisation reforms, fewer analyse the perspectives of vocational educators on such reforms. How vocational educators negotiate the potential clash of values when marketisation reforms are enacted within the sector remains relatively unexplored. This paper aims to incorporate these perspectives in order to explore and help explain the responses of vocational educators to such changes. To do so the paper draws on concepts from Legitimation Code Theory, a sociological framework for analysing practices and beliefs. Specifically, it enacts ‘autonomy codes’, which reveal how external forces impact upon the internal practices of a social field. These concepts are used to analyse the beliefs and perceptions of a group of vocational educators in Australia who are undergoing marketisation reforms. The analysis suggests that many educators are experiencing a growing ‘code clash’ between the goals they attribute to reforms and their own beliefs about public education and the expectations of their students, one which problematises their capacity to reconcile these sets of values and colours their views of changes in the sector.     

On the effects of training inductive reasoning: How far does it transfer and how long do the effects persist?

Using the same program, two training experiments have been conducted in a Dutch and in a German elementary school. The common expectation was that training in inductive reasoning would transfer both on intelligence tests measuring inductive reasoning and on math performance. Furthermore, it was expected that the training effects would persist for at least some months after training had ended. In experiment 1 (N=34), a rather short training period turned out to be effective with respect to the intelligence test performance but not with respect to math performance. In experiment 2 (N=23), the amount of training in inductive reasoning was systematically varied. It could be shown that transfer on intelligence test as well as on math performance was linearly dependent on the amount of prior training. The training effects were found to persist between four and nine months after training.     

Do grades in higher education matter for labour market rewards? A multilevel analysis of all Norwegian graduates in the period 1990–2006

This paper examines the effects of grades from higher education on labour market outcomes. Economic theory predicts that grades are rewarded in the labour market because employers regard them as an expression of valuable skills or a signal of other sought after attributes. Social closure, however, may give reason to expect no effects. Whether good grades are rewarded in the labour market is thus uncertain. This paper addresses this question by examining whether employers tend to reward good grades in the form of employment and higher income. Previous research has demonstrated that the returns to education vary according to structural–institutional labour market settings. We examined the interaction effects between grades and field-specific characteristics and between grades and sector by analysing data on all graduates in these educational programmes at Norwegian universities and university colleges from 1990 through 2006. The education data are linked with multiple other data sources such as the national tax register and the national employment register. We find that good grades have positive effects on both income and employment and that these effects are influenced by both the type of education and sector.     

The Cost-Effectiveness of Increasing Hours Per Week of Early Intervention Services for Young Children with Disabilities

Although there is a widespread belief that increasing the hours of early intervention services for children with disabilities will result in increased benefits for the participating children and their families, there is little research evidence to support this point of view. In this study, young children with disabilities were randomly assigned to receive either one hour per week of early intervention services, or three hours per week. Measures of child and family outcomes over the subsequent five-year period demonstrated no consistent benefits associated with increasing the hours of intervention. Possible reasons for the lack of benefits are discussed in the context of previous research.

Teaching children with autism through task variation in physical education.

The purpose of the study was to determine whether the technique of task variation (with maintenance tasks interspersed) (TV) is more effective in the acquisition of gross motor skills for students with autism than a constant task (CT) condition in a physical education setting. Subjects were 12 male students with autism, ages 11 to 15 years. The study included pretest-posttest administration of the I CAN assessment of Gross Motor Skills to assess skills such as overhand throw, kick, and vertical jump. After a 6-week treatment period, the TV condition was significantly more effective than the CT condition, at the .05 level.     

Mapping inclusion of a child with autism in a mainstream kindergarten: how can we move towards more inclusive practices?

ABSTRACT

This study identify and reflect on barriers to inclusion that children with autism can meet in kindergarten. We use a single case study with participant- and video observation to map inclusion for a single 5-year-old boy with autism, in a mainstream kindergarten in Norway. Analysis identified three modes of inclusion; distance-keeping, maintaining proximity and interacting. The mapping procedure demonstrated that barriers to inclusion continue to operate. The extent of the child's participation seemed to relate to what he was doing and who he was with; overall, limited social inclusion amongst peers being achieved. Results indicated that predictable frameworks and teacher support increased participation. We discuss how participation for children with autism can be promoted. Our study points toward the need to extend current adaptations and support to children with autism within the educational settings, to enable a more inclusive practice.     

Construction and validation of a communication based emotional support scale

A review of the emotional support and social support literature indicates a paucity of instruments which directly measure the phenomena of interest. While many have utilized assessments of “strong” or “weak” links between relational partners, they have not examined the communication modalities specifically. They have also tended to view emotional support as a unilateral product of a source or receiver rather than a product of communicative interactions. In order to examine support more carefully, a unidimensional instrument was developed to measure the communication of emotional support in relationships. As tests of convergent validity, it was suggested that perceptions of emotional support will be positively correlated to perceptions of relational solidarity and relational quality. The final instrument consisted of 13 communication based items with high reliability and evidence of internal, face, and convergent validity.
