The effect of mindfulness on extinction and behavioral resurgence

In the present experiments, we investigated the effects of mindfulness on behavioral extinction and resurgence. Participants received instrumental training; either they received FI training (Experiment 1), or they were trained to emit high rates and low rates of response via exposure to a multiple VR yoked-VI schedule prior to exposure to a multiple FI FI schedule in order to alter their rates of responding learned during Experiment 2. Participants were then exposed to either a focused- (mindfulness) or an unfocused-attention induction task. All participants were finally exposed to an extinction schedule in order to determine whether a mindfulness induction task presented immediately prior to extinction training affected extinction (Experiment 1) and behavioral resurgence (Experiment 2). During the extinction phase, the rates of responding were higher in the control group than in the mindfulness group, indicating that the mindfulness group was more sensitive to the contingencies and, thus, their prior performance extinguished more readily (Experiment 1). Moreover, rates of response in the extinction components less precisely reflected previous training in the mindfulness group, suggesting less resurgence of past behaviors after the mindfulness induction (Experiment 2).     

Stokingham Sixth Form College: Institutional culture and dispositions to learning

Learning is high on the political agenda for post-compulsory education and training in England. Official discourses about learning assume a predominantly individualist stance, despite the development of theoretical models that stress the contextual and situated nature of learning. In a study following 50 young people through further education over 4 years, it became apparent that the institutional culture of the colleges had a significant impact upon students' dispositions towards their learning. In this paper, we explore the nature and significance of this impact in a case-study sixth form college: an under-researched sector of educational provision. This is followed by a brief discussion of the implications of our analysis for issues of access, widening participation and inequality in relation to current proposals to reform age 16-19 educational provision in England. We conclude by identifying some of the questions about the fine-grained nature of that college culture that our data does not permit us to address directly.     

A Survey into Mainstream Teachers' Attitudes Towards the Inclusion of Children with Special Educational Needs in the Ordinary School in one Local Education Authority

Attitudes of mainstream teachers towards the inclusion of children with special needs in the ordinary school were surveyed soon after the release of the Green Paper. The survey was carried out in one Local Education Authority in the south-west of England and the sample comprised of 81 primary and secondary teachers. The analysis revealed that teachers who have been implementing inclusive programmes, and therefore have active experience of inclusion, possess more positive attitudes. Moreover, the data showed the importance of professional development in the formation of positive attitudes towards inclusion. In particular, teachers with university-based professional development appeared both to hold more positive attitudes and to be more confident in meeting the IEP requirements of students with SEN. The role that training at both pre-service and post-service levels has in the development of teachers' support for inclusion is discussed.     

Child sexual abuse: A study of prevalence in Great Britain

Of 2019 men and women (aged 15 years and over) interviewed as part of a MORI Survey of a nationally representative sample of Great Britain, 10% reported that they had been sexually abused before the age of 16 (12% of females; 8% of males). There was no increased risk associated with specific social class categories or area of residence. For all types of sexual abuse, the mean age of victims when first abused was significantly lower for females. Subjective reports of the effects of sexual abuse indicated that the majority (51%) felt harmed by the experience, while only 4% reported that it had improved the quality of their life. We estimate that there are over 4.5 million adults in Great Britain who were sexually abused as children, and that a potential 1,117,000 children will be sexually abused before they are 15 years of age. At least 143,000 of these will be abused within the family. The social and mental health implications are enormous, and the authors suggest that an effective intervention and prevention policy is urgently required.     

The role of response-reinforcer correlation in signaled reinforcement effects

In three experiments, we examined the effects of signaling reinforcement during operant responding in order to illuminate the factors underlying instrumental overshadowing and potentiation effects. Specifically, we examined whether signaling reinforcement produces an enhancement and attentuation of responding when the response-reinforcer correlation is weak and strong, respectively. In Experiment 1, rats responded on variable-ratio (VR) or variable-interval (VI) schedules that were equated for the number of responses emitted per reinforcer. A signal correlated with reinforcement enhanced response rates on the VR schedule, but attenuated response rates were produced by the signal on the VI schedule. In Experiment 2, two groups of rats responded on a VI schedule while the two other groups received a conjoint VI, negative fixed-ratio schedule in which the subjects lost the availability of reinforcements if they emitted high response rates. A reinforcement signal attenuated responding for the simple VI groups but not for the animals given the negative fixed-ratio component, although the signal improved response efficiency in both groups. In Experiment 3, a poor correlation between responding and reinforcement was produced by a VI schedule onto which the delivery of response-independent food was superimposed. A signal for reinforcement initially elevated responding on this schedule, relative to an unsignaled condition; however, this pattern was reversed with further training. In sum, the present experiments provide little support for the view that signaling reinforcement enhances responding when the response-reinforcer correlation is weak and attenuates responding when this correlation is strong.     

Sensory, cognitive, and linguistic factors in the early academic performance of elementary school children: The Benton-IU project

Standardized sensory, perceptual, linguistic, intellectual, and cognitive tests were administered to 470 children, approximately 96% of the students entering the first grade in the four elementary schools of Benton County, Indiana, over a 3-year period (1995--1997). The results of 36 tests and subtests administered to entering first graders were well described by a 4-factor solution. These factors and the tests that loaded most heavily on them were reading-related skills (phonological awareness, letter and word identification); visual cognition (visual perceptual abilities, spatial perception, visual memory); verbal cognition (language development, vocabulary, verbal concepts); and speech processing (the ability to understand speech under difficult listening conditions). A cluster analysis identified 9 groups of children, each with a different profile of scores on the 4 factors. Within these groups, the proportion of students with unsatisfactory reading achievement in the first 2 years of elementary school (as reflected in teacher-assigned grades) varied from 3% to 40%. The profiles of factor scores demonstrated the primary influence of the reading-related skills factor on reading achievement and also on other areas of academic performance. The second strongest predictor of reading and mathematics grades was the visual cognition factor, followed by the verbal cognition factor. The speech processing factor was the weakest predictor of academic achievement, accounting for less than 1% of the variance in reading achievement. This project was a collaborative effort of the Benton Community School Corporation and a multidisciplinary group of investigators from Indiana University.     

The influence of brief stimuli uncorrelated with reinforcement on choice between variable-ratio schedules

Experiment 1 investigated the behavior of rats trained to leverpress on a concurrent variable ratio (VR) 30 VR-30 schedule with a brief, 500-msec, light occurring at the midpoint of the ratio on one of the levers. Higher response rates were recorded on the lever associated with this stimulus, a finding that paralleled the effect produced by inserting primary reinforcement at the midpoint (i.e., by training on a concurrent VR-30 VR-15 schedule). Similar results were found in Experiment 2 using a concurrent VR-20 VR-20 schedule with a 2-sec visual stimulus presented midway through one of the components. In addition, a brief stimulus inserted midway through the VR-20 component of a concurrent VR-20 VR-10 schedule retarded the development of a difference in response rates between the components relative to a VR-20 VR-10 group lacking the signal. In Experiment 3, multiple VR VR schedules were used. Again, the response rate was higher in the component that had the added stimulus or, for a second group of subjects, on the component with the smaller response requirement. Probe-choice trials revealed a preference for the component that generated the higher rate in both groups. Presenting a stimulus partway through a ratio appears to reduce the effect on response rate and choice of a large ratio value.     

Meaning-led learning for pupils with severe and profound and multiple learning difficulties

This paper proposes that learning and teaching for pupils with severe and profound and multiple learning difficulties could be enhanced by a closer focus on emotional factors and on the careful identification of what is meaningful for them. Phil Goss, senior lecturer in counselling and psychotherapy at the University of Central Lancashire draws on understandings about emotional development gleaned from child psychiatry and psychotherapy to inform our awareness of the deep-seated factors that may influence the complex needs of these pupils. He describes a research study in which he analysed findings from interviews with parents and carers about their perceptions of what is meaningful for their children. These outcomes are elaborated using findings from a pilot study on one pupil in which perceptions about what is meaningful for him were used to inform the ongoing planning of his learning. Phil Goss then uses the implications of this study to argue for fuller and more systematic involvement by parents and carers in planning for pupils with severe, and profound and multiple learning difficulties. Finally he suggests ways in which access to learning could be rendered more fruitful by adopting a meaning-led approach.     

The Development of Perspective Taking: Understanding Differences in Information and Weighting

2 separate aspects of perspective taking are that judgments attributed to another should depend on the information available to the other (Information effect) and on how the other's use of information differs from one's own (Weighting effect). These 2 aspects of perspective taking were studied in a moral judgment task with preschoolers, and second and fifth graders. Subjects were read a series of stories about a little boy transgressing and asked to make judgments from both their own perspective and that of a mother character in the stories. The mother story character had either the same information as the subject or only partial information. Valence of intention and consequence and the amount of mother's knowledge varied factorially. Subjects were clustered using scores derived from the judgements. 3 clusters were found that showed different levels of perspective-taking ability. There was a developmental progression in the 3 levels of perspective taking. Subjects in the Harshness cluster attributed harsher judgments to the mother perspective. Subjects in the Weighting cluster weighted information differently depending on the perspective from which they judged. Subjects in the Information-and-Weighting cluster weighted information differently depending on perspective, and also considered the amount of information available to the mother character in attributing judgments. The findings are compared to current theory on the development of perspective taking. Future research and theory need to consider the influence of both information and weighting differences on performance in perspective-taking tasks.
