Programming generalization and maintenance of treatment effects across time and across settings

Effects of three experimental and one control strategy were investigated in facilitating generalization and maintenance of treatment effects after two months in a token-economy classroom. At the conclusion of treatment, subjects were randomly assigned to one of three maintenance strategies or a control group and returned to their regular classrooms. The maintenance strategies were peer reprogramming, equating stimulus conditions between the experimental and regular classrooms, and teacher training in behavior management techniques. The maintenance strategies were implemented in the regular classroom for a two-month period and then terminated. Results indicated a powerful treatment effect produced by the token economy. Behavior maintenance effects following treatment were also obtained. The mean per cent appropriate behavior for the peer reprogramming and equating stimulus conditions strategies was significantly greater than the mean for the control subjects. The teacher training and control group means were not significantly different.     

Teaching students with autism spectrum disorder to tolerate haircutting

We describe intervention with 2 adolescent male students who had autism spectrum disorder (ASD) and resisted haircutting performed by care providers at a residential school. The students were exposed to a graduated hierarchy of steps including the presence of hair clippers, and increased duration of hair clippers against their scalp and hair. Edible reinforcement was presented contingent on completion of a step without interfering behavior. Both students learned to tolerate all of the steps in the graduated hierarchy and a full haircut with maintenance at 2-, 4-, and 6-month follow-up. The study supports previous tolerance-training research with children and youth who have intellectual and developmental disabilities and resist personal care and hygiene routines.     

Contrast Effects in Performance Ratings: Another Look Across Time

Récemment, Murphy, Balzer, Lockart et Eisenman (1985) rapportèrent que les effets de contraste dans une comparaison intra-personnelle disparaissent subséquemment à un court délai d'évaluation d'un stimulus-cible. Les deux expérimentations que nous décrivons indiquent que les effets de contraste dans une comparaison inter-personnelle résistérent même après un délai de trois semaines entre l'évaluation d'un stimulus de référence et d'un stimulus-cible. Dans l'expérience 1, 270 étudiants furent répartis en neuf groupes expérimentaux ( n = 30) qui représentent toutes les combinaisons possibles de trois indices de performance (élevé, bas, moyen) en deux temps différents. Un effet de contraste significatif fut observé chez ceux des participants qui visèrent et obtinrent une performance moyenne au Temps 2 (omega au carré= 0.16). Dans l'expérimentation 2, 270 étudiants MBA (avec un minimum d'expérience de deux années d'assistanat) répétèrent les résultats de l'expérimentation 1 (omega au carré= 0.18). Ces résultats groupés indiquent que les effets de contraste résistent au temps et valorisent les projets de recherche dans ce domaine.     

Responses to the AAR‐Teagle White Paper: “The Religious Studies Major in a Post‐9/11 World”

In October 2008 The American Academy of Religion published the findings of an eighteen month study (conducted with funding from the Teagle Foundation) on “The Religious Studies Major in a Post–9/11World: New Challenges, New Opportunities.” Re‐published here, this AAR‐Teagle White Paper provides the opportunity for four respondents to raise issues and questions about the teaching of religion in their own institutional contexts. First, Jane Webster describes how the White Paper's “five characteristics of the religion major” find expression in her biblical literature course. Then James Buckley suggests some of the general level teaching issues provoked by the study and analyzes how well the White Paper aligns with how the teaching of religion is conceived in his Catholic university context. Tim Jensen draws comparisons between the White Paper and the higher education structures and goals from his university context in Denmark, raising questions about what motivates students to major in religious studies, the “utility” of a religious studies major, and whether students' religious and spiritual concerns ought to enter the classroom. And finally Stacey Floyd‐Thomas finds surprising similarities between the state of the religion major and the various crises facing contemporary North American theological education.     

The impact of school connectedness on violent behavior, transport risk-taking behavior, and associated injuries in adolescence

Adolescents engage in many risk-taking behaviors that have the potential to lead to injury. The school environment has a significant role in shaping adolescent behavior, and this study aimed to provide additional information about the benefits associated with connectedness to school. Early adolescents aged 13 to 15 years (N = 509, 49% boys) were surveyed about school connectedness, engagement in transport and violence risk-taking, and injury experiences. Significant relations were found between school connectedness and reduced engagement in both transport and violence risk-taking, as well as fewer associated injuries. This study has implications for the area of risk-taking and injury prevention, as it suggests the potential for reducing adolescents' injury through school based interventions targeting school connectedness.     

Spatial navigational impairments in hydrocephalus

Whilst much is known about the neuropathological consequences of hydrocephalus, there have been comparatively few studies of the cognitive impairments associated with it. Studies using standardised tests of cognitive function have identified a general pattern of impairments, with patients exhibiting particular difficulty on tests of spatial memory and executive function. A strong prediction is that these deficits are likely to affect daily wayfinding behaviour, and we report a study of spatial and navigational abilities in a group of patients with hydrocephalus but without spina bifida. Participants completed a range of experimental tasks assessing spatial cueing behaviour, landmark memory and route-learning, and idiothetic path integration. This patient group was compared to a control sample matched on verbal, spatial, and intelligence measures, and hydrocephalus was found to be associated with relative impairments in each of the tasks. Patients exhibited reduced sensitivity to spatial cueing, less accurate route-learning, poorer memory for landmark objects, and less accurate spatial updating (with particular impairments in the calculation of heading). Overall, these data represent the first empirical demonstration of navigational impairments in hydrocephalus, and we suggest some of the cognitive, neural, and individual differences factors that may contribute to the pattern of performance reported.     

Providing feedback to organizational members: A reconsideration

Feedback frequency is identified as a critical issue in the administration of feedback in organizations. Current assumptions in the literature concerning feedback frequency are critically discussed and areas for future research are identified. Suggestions are made pertaining to the subsequent treatment of feedback in the organizational literature and the appropriate role of an organization in the feedback process. Implications from this research area for practitioners are suggested.     

The use of positive reinforcement in conditioning attending behavior

Individual conditioning techniques were applied in a controlled setting to increase attending behavior of an underachieving 9-yr-old male subject. The procedure involved: (1) determining a stable response pattern, (2) introducing a treatment variable to establish a high rate of task-attending behavior, (3) measuring the effect of withdrawal of the treatment variable after attaining criterion performance, and (4) transferring control to the classroom. The interval of attending behavior required for reinforcement was systematically increased from 30 sec to 600 sec as the behavior came under experimental control. Manipulating the reinforcing contingencies measurably changed the proportion of attending behavior and the frequency and duration of non-attending events. Once the behaviors were under experimental control, procedures were established to program generalization and to maintain the behavior outside the experimental setting.
