Effects of stimulus dimension and of trial and intertrial illumination on acquisition of a match/mismatch task by pigeons

Birds were trained on a higher order conditional discrimination task, one that required birds to match samples and comparisons on some trials and to mismatch on other trials. Which task component was in effect was indicated by the level of chamber illumination (houselight-on and houselight-off instructions). Acquisition of the components of a color (red and green) match/mismatch task in the first half of the experiment was not differentially affected by the level of illumination associated with each task component, by houselight changes per se, or by the level of illumination during the intertriai interval (ITI). However, when shapes (plus and circle) were used to train the task in the second half of the experiment, performance on the houselight-cued task component exceeded performance on the dark-cued task component, and ITI illumination facilitated performance on both task components. These results suggest that attention to shape stimuli, but not to colors, may vary systematically as a function of chamber illumination level.     

Norm-referenced,Criterion-referenced,and Dynamic Assessment: What exactly is the point?

Assessment of individual children and young people has remained a major focus of professional activity for educational psychologists (EPs) and one surrounded by continuing controversy. Despite the arguments of the 'reconstructing movement' of the 1970s, and ensuing debates, individual assessment has survived seemingly as strong as ever. Subsumed within arguments concerning the prominence given to individual assessment, another set of discussions has concerned the paradigms from which such professional activity might derive. Located among constructs contrasting environment with individual and static with interactive perspectives, the particular debate within individual assessment has centred on the relative merits of norm-referenced, criterion-referenced, curriculum-based and dynamic methods. This article presents a taxonomy of purposes and procedures deriving from these major assessment paradigms. This collection is illustrated by examples taken from EP reports, and the relative familiarity and use of each approach by one major audience group is evaluated through examining questionnaire responses from 59 Special Educational Needs Coordinators within one Local Education Authority.     

An Online Course to Prepare Preservice Teachers to Promote Movement Integration

Previous research has not explored the potential of distance learning to prepare preservice teachers (PCTs) for promoting children’s physical activity. The purpose of this study was to (a) examine the perceptions and experiences of PCTs, inservice classroom teachers, university instructors, and elementary students who were involved in a semester-long distance delivery course that included a service-learning (SL) component with an emphasis on classroom movement integration (MI). Using a qualitative single case study design, interviews, observations, and artifacts (e.g. PCTs’ reflections and academic work) were thematically analyzed. Findings produced three themes including student-centered approach, benefit/importance of physical activity, and connect and reflect. These themes showed that participants’ perceptions and experiences support constructivist-guided SL using a distance delivery design. This study adds to the emerging research base on school-university partnerships to support schools in the implementation of comprehensive school physical activity programming.     

Dermatoglyphics and the persistence of 'Mongolism'

In 1961, a prestigious group of medical researchers called on their colleagues to stop using the language of 'Mongolism' to describe people with what we now call 'Down's syndrome' (or Trisomy 21). This call responded to new knowledge about the biological basis of Down's syndrome: rather than the product of racial degeneration, as had been hypothesized in the 19th century, the condition was the result of an extra chromosome, dubbed '21'. Yet, despite this plea, the terms 'Mongol' and 'Mongolism' continued in scientific use through the 1960s. Drawing on published and archival materials, I argue that the new knowledge about chromosomes did not rupture older patterns of scientific practice or interpretation, and with them, older terminological habits. The persistence of the language of Mongolism reflects the continuity of a network of older approaches to interpreting the condition within the community of human and medical geneticists, including an enduring diagnostic and interpretive technology, dermatoglyphics. Old networks were not supplanted; they were re-aligned.     

Contributions of Maternal Attention-Deficit Hyperactivity and Oppositional Defiant Disorder Symptoms to Parenting

Objective. The goal of the current study was to examine the impact of maternal attention-deficit hyperactivity disorder and oppositional defiant disorder symptoms on several dimensions of parenting. Design. One-hundred seven mothers of young adolescents provided ratings of their own attention-deficit hyperactivity disorder, oppositional defiant disorder, depressive symptoms, and parenting behavior, as well as their adolescents’ aggressive behaviors. Results. Hierarchical regression analyses examined the relative contributions of attention-deficit hyperactivity disorder and oppositional defiant disorder symptoms to parenting. Greater levels of maternal attention-deficit hyperactivity disorder symptomatology were associated with poorer monitoring, whereas more oppositional defiant disorder symptoms were associated with lower levels of parenting involvement and positive reinforcement and higher levels of overreactivity and use of corporal punishment. Conclusions. Maternal oppositional defiant disorder behaviors were particularly associated with negative, affective dimensions of parenting. Understanding the impact of maternal attention-deficit hyperactivity disorder symptoms on parenting may require consideration of concomitant maternal oppositional defiant disorder symptoms.     

Emotion regulation in context: the jealousy complex between young siblings and its relations with child and family characteristics

Jealousy is a social emotion that has received little attention by developmental researchers. The current study examined sibling jealousy and its relations to child and family characteristics in 60 families with a 16-month-old toddler and an older preschool-age sibling. Sibling jealousy was elicited in social triads consisting of a parent (mother or father) and the two siblings. Positive marital relationship quality (i.e., love and relationship maintenance) was a particularly strong predictor of the older siblings' abilities to regulate jealousy reactions in the mother sessions. Younger siblings' jealous affect with mothers was linked to the child's temperament, whereas older siblings' jealous affect with mothers was related to the child's emotional understanding. Younger siblings displayed more behavioral dysregulation in the mother-sibling triads if there was greater sibling rivalry reported by mothers. Session order (i.e., which sibling was challenged first in the jealousy paradigm) had a strong effect on both the affect and behavioral dysregulation displayed by the older and younger siblings. Results are discussed with respect to the need for future research to consider social relationships as developmental contexts for young children's emotion regulation.     

Issues in the sexual molestation of deaf youth

An overview is provided of issues involved in sexual abuse in schools (as well as the general problem of child molestation in society), some characteristics of pedophiles and hebephiles, and data on how sexual molesters are dealt with by the criminal justice system. Specific information is provided on how sexual abuse becomes an issue in schools for children who are deaf, what can be done to prevent it, and symptoms to look for in identifying deaf children who are being victimized.     

‘Whatever Else May Be Going On:’ Sharing Books in Bechdel’s Fun Home

ABSTRACT

In Fun Home, Alison Bechdel recounts a version of her family’s history through moments of meaningful textual exchange. This paper takes up one such moment, when Alison’s father Bruce offers his daughter a queer text, which she uses both to understand her own sexuality and to broach the the queer connection she has just learned they have. I read this exchange as a case study for considering what happens when we share our meaningful books with others. Here I map the way literary works function in this text both developmentally, following Grumet’s reading of Winnicott, and erotically, following Bechdel’s own narration. I read the act of sharing books as an act of love that helps build the world worth noticing, core relationships, and individual identities, reading too how literature functions as ‘currency’ in the difficult father-daughter relationship at hand in this graphic memoir.     

Student assessment of teaching in higher education

Plans to introduce campus-wide assessments of college or university teaching which are largely dependent on student ratings are seen as a threat to academic freedom in those institutions with little or no experience of this form of evaluation. While regular student evaluations of teaching are very common in North America, their introduction is only now being considered in colleges and universities in a number of other countries. Research on the reliability and validity of student ratings indicate that they are capable of providing valuable information about the quality of teaching. Depending on the survey used, this type of evaluation may be used to provide evidence of teaching ability to staffing committees or to suggest ways of improving teaching. The paper concludes with a set of recommendations for higher education institutions which are considering the regular assessment of all teachers by their students.     

Reminder-induced attenuation of the effect of relative stimulus validity

The roles of deficient acquisition and deficient expression of learned information in the effect of relative stimulus validity were examined using rats in a conditioned lick suppression paradigm. Recovery from the effect without further pairings of the conditioned stimulus (CS) and the unconditioned stimulus (US) would favor an interpretation of the relative validity effect based on a latent CS-US association as distinct from a failure to acquire the CS-US association. As a potential recovery manipulation, “reminder” treatments, consisting of the US alone (Experiment 1) or the CS alone (Experiment 2), were administered following relative validity training. In both cases, subjects for which the CS target was of low relative predictive validity exhibited enhanced responding relative to appropriate controls. Additionally, Experiment 2 showed that the amelioration of the relative validity deficit was stimulus specific. Thus, the results of these experiments support previous suggestions that the performance deficit resulting from low relative stimulus validity is due, at least in part, to a failure to express acquired information (Cole, Barnet, & Miller, 1995a).
