Replacement of event-generated memories of nonreinforcement with signal-generated memories of reinforcement during partial reinforcement training: Effect on resistance to extinction

Event-generated memory refers to the memory of a reinforcement (R) or nonreinforcement (N) event from an immediately preceding trial;signal-generated memory refers to the memory of a temporally remote R or N, retrieval of which is generated by presentation of a signal with which the memory is associated (Haggbloom, 1988). In each of three experiments, Group Signal-R received runway discrimination training in Phase 1 to establish a stimulus as a signal for R, and partial reinforcement training in Phase 2. An extinction test measured learning about the memory of nonreward (S^N)—learning that occurs when S^N is retrieved on R trials that follow N trials. In Group Signal-H, those R trials were accompanied by the signal for R, a treatment we hypothesized would generate retrieval of the memory of reinforcement (S^R) so that signal-generated S^R would replace event-generated S^N as the operative memory, thereby eliminating the increased resistance to extinction normally produced by PRF training. In each experiment, Group Signal-R was less resistant to extinction than was a control group conditioned to respond to-event-generated S^N. Extinction was as rapid in Group Signal-R as it was in a consistent reinforcement control group (Experiment 1) and in a group given intertrial reinforcements to interfere with learning about S^N (Experiment 3). Experiment 2 tested two alternative interpretations of the failure to learn about S^N in Group Signal-R. Those alternatives were found to be less viable than the hypothesis that the signal for R actively recruited retrieval of a competing memory.     

The ‘Employer Engagement Cycle’ in Secondary Education: analysing the testimonies of young British adults

Work experience placements are mandatory in the UK for all young people aged 16–18 in education, and their employability effects and associated wage premia are well noted in the literature. Through Bourdieu’s lens, this article analyses and conceptualises a unique data set of reflective testimonies submitted in response to a YouGov survey of over one thousand young people. Different capitals are detected, their distributions are observed, and correlations with key variables such as social background and school type are reported. Emerging through young people’s perceptions of employer engagement is a complex web of human, social and cultural capital accumulation. Overlaps are frequent, with newly acquired forms of capital often activating others. We argue that because of the cyclical nature of employer engagement gains, benefits accumulate exponentially for some young people while leaving others increasingly detached from the capitals that are most important for labour market success.     

Design Dynamics of a Leadership Assessment Academy: Principal Self-Assessment Using Research and Technology

This article describes and analyzes the design dynamics of a school principal self-assessment process, provided through a three-day, state-approved Leadership Assessment Academy, which allows principals to experience and reflect on important self-assessment data that leads to a personal professional growth plan. Designing and implementing such an academy is complex and requires careful consideration of all aspects of the principalship and the requirements set forth by the state regarding principal assessment and professional growth plans. A primary challenge of this leadership academy is in providing principals with a self-assessment experience that is meaningful and accurate using carefully designed assessment techniques and technology, and that can serve as a viable alternative to the traditional paper and pencil assessment tools that require very little personal involvement in defining and producing the principal's professional growth plan.     

PARENT‐TEACHER COMMUNICATION ABOUT CHILDREN WITH AUTISM SPECTRUM DISORDER: AN EXAMINATION OF COLLABORATIVE PROBLEM‐SOLVING

Effective parent‐teacher communication involves problem‐solving concerns about students. Few studies have examined problem‐solving interactions between parents and teachers of children with autism spectrum disorder (ASD), with a particular focus on identifying communication barriers and strategies for improving them. This study examined the problem‐solving behaviors of parents and teachers of children with ASD. Participants were 18 teachers and 39 parents of children with ASD. Parent‐teacher dyads were prompted to discuss and provide a solution for a problem that a student experienced at home and at school. Parents and teachers also reported on their problem‐solving behaviors. Results showed that parents and teachers displayed limited use of the core elements of problem‐solving. Teachers displayed more problem‐solving behaviors than parents. Both groups reported engaging in more problem‐solving behaviors than they were observed to display during their discussions. Our findings suggest that teacher and parent training programs should include collaborative approaches to problem‐solving.     

The Importance of Demographic, Social, and Political Context for Estimating Policy Impacts: Comment on “Implementing New York's Universal Pre-Kindergarten Program”

Morrissey, Leikes, and Cochran (this issue) raise concerns about potential negative effects of state pre-kindergarten (pre-K) on the early care and education system. To put their study in context, I reviewed national demographic and enrollment trends. I found little evidence of negative effects from state pre-K policy. One reason may be that population growth and child care policies mitigated potential negative impacts of pre-K expansion. However, national averages could conceal important local variations or even nationwide variations when there are offsetting gains and losses. Children under age 5, their families, and their teachers all likely gained from increases in public pre-K. Infant/toddler care in private programs expanded as quickly as public pre-K. Morrissey and colleagues' small data set from New York has serious limitations, but some of the most salient findings are consistent with the national picture. The study offers lessons and suggests topics for future research on the influence of pre-K policy on the early care and education system.     

A Comparison of Self-Adapted and Computerized Adaptive Tests

According to item response theory (IRT), examinee ability estimation is independent of the particular set of test items administered from a calibrated pool. Although the most popular application of this feature of IRT is computerized adaptive (CA) testing, a recently proposed alternative is self-adapted (SA) testing, in which examinees choose the difficulty level of each of their test items. This study compared examinee performance under SA and CA tests, finding that examinees taking the SA test (a) obtained significantly higher ability scores and (b) reported significantly lower posttest state anxiety. The results of this study suggest that SA testing is a desirable format for computer-based testing.     

Conditioned and unconditioned stress-induced analgesia: Stimulus preexposure and stimulus change

Aversive events such as electric shock lead to analgesia. There have been differing views with regard to whether the aversive event itself can lead to analgesia as a direct unconditioned reaction, or whether the analgesia is instead a reaction to fear conditioned to cues present during shock or to other associative processes initiated by the aversive event. Maier (1989, 1990) has argued that aversive events such as shock lead to both types of analgesia, with the type observed depending on test conditions. Unconditioned analgesia was argued to be present soon after shock, with conditioned analgesia replacing the unconditioned form if the subject is allowed to remain in the shock environment. Consistent with this argument, the experiments reported here show that (1) preexposure to the environment in which shock later occurs has no effect on the analgesia soon after shock, but eliminates the later analgesia; (2) the initial postshock analgesia is unaffected by removing the subject from the shock environment to a different environment, but the later reaction is prevented by such a change; (3) returning the subject to the shock environment after confinement in a nonshock environment rearouses an analgesic reaction; and (4) this rearousal does not occur if the subject has first been confined to the shock environment without shock.     

Mapping the development of a new MA programme in higher education: comparing privately held perceptions of a public endeavour

After spending a year working on the development of a new online Master’s programme in higher education, members of the development team were interviewed to reveal their thoughts about the nature of the programme. The dialogue of each interview was summarised as a concept map. Analysis of the resulting maps included a modified Bernsteinian analysis of the focus of the concepts included in terms of their semantic gravity (i.e. closeness to context) and the degree of resonance with the underpinning regulative discourse of the programme. Data highlight a number of potential issues for programme delivery that centre around the use of appropriate language to manage student expectations in relation to the process of learning and the emotional responses this can stimulate, as well as the tensions that can be foregrounded between the demands of teaching and research within a university environment.     

Policy mobilities and methodology: a proposition for inventive methods in education policy studies

ABSTRACT

The argument of this paper is that new methodologies associated with the emerging field of ‘policy mobilities’ can be applied, and are in fact required, to examine and research the networked and relational, or ‘topological’, nature of globalised education policy, which cuts across the new spaces of policymaking and new modes of global educational governance. In this paper, we examine the methodological issues pertaining to the study of the movement of policy. Informed by contemporary methodological thinking around social network analysis and the ethnographic notion of ‘following the policy’, we discuss the limitations of these approaches to adequately address presence in policy network analysis, and the problem of representing speed and intensity of policy mobility, even while these attempt to solve the problem of relationality and territoriality. We conclude that the methodologies of policy mobility are inexorably intertwined with the (constantly) changing phenomena under examination, and hence require what Lury and Wakeford describe as ‘inventive methods’.
