The role of the clinical psychologist on a burn unit in a general teaching hospital

This paper reviews the core skills that a clinical psychologist brings to a burn unit and suggests a model for optimal psychological management of burn patients, families, and staff. Recovery from a burn injury involves three stages that comprise (a) acute treatment of severe medical complications, (b) adjustment to hospitalization, and (c) long-term rehabilitation. Each stage contains numerous issues that the clinical psychologist should monitor and manage. Assessment of patients at risk, early intervention, and specialist management are highlighted as critical components of effective psychological management of burn injury in a multidisciplinary team context.     

Primes, contingent attention, and training: effects on a child's motor behavior

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.     

An analysis of public posting in reducing speeding behavior on an urban highway

The effects of public posting on speeding behavior on an urban highway were assessed using a reversal design. During baseline the percentage of drivers speeding was measured with a concealed radar unit. During the daily posting condition a highway sign was installed which provided feedback on the percentage of drivers not speeding yesterday and the best record to date. This sign was then covered and reintroduced. Results indicated that the sign was effective in reducing speeding behavior. Furthermore, the effects were most pronounced in reducing the speeds of the faster drivers. Next, daily and weekly postings were compared with the sign alone without numerical feedback: results revealed that the weekly posting condition was as effective as the daily posting condition, but that the sign had no influence when numbers were not posted. Finally, the weekly posting procedure remained effective during a 6-month follow-up condition.     

INCREASING SPELLING ACHIEVEMENT: AN ANALYSIS OF TREATMENT PROCEDURES UTILIZING AN ALTERNATING TREATMENTS DESIGN

Two studies which examine the effectiveness of spelling remediation procedures are reported. In both studies, an alternating treatment design was employed. In the first study, positive practice overcorrection plus positive reinforcement was compared to positive practice alone and a no-remediation control condition. In the second study, positive practice plus positive reinforcement was compared to a traditional corrective procedure plus positive reinforcement and a traditional procedure when used alone. Results of both studies indicated that the combined positive practice plus positive reinforcement procedure was more efficient and that it was preferred by the children. Following brief training under this combined procedure, all children demonstrated 100% spelling accuracy.     

Varying Problem Effort and Choice: Using the Interspersal Technique to Influence Choice Towards More Effortful Assignments

College students were exposed to two pairs of mathematics assignments. Assignment Pair A included a high-effort assignment containing 18 long three-digit × two-digit (3×2) multiplication problems with all numerals in each problem being equal to or greater than four and a moderate-effort assignment that contained nine long problems and nine interspersed moderate 3×2 problems with numerals less than four. Assignment Pair B contained similar assignment sheets, the exception being that the high-effort assignment contained six additional one-digit × one-digit (1×1) problems interspersed following every third 3×2 problem. After working on each assignment pair, students ranked assignments and chose a new assignment for homework. Analysis of Assignment Pair A revealed that students overwhelmingly preferred the moderate-effort assignment. Analysis of interaction effects showed that when additional brief problems were added to the high-effort assignments, the proportion of students who chose the high-effort assignment for homework and ranked it as being less difficult, time consuming, and effortful increased significantly. Results support previous research on effort and choice and the hypothesis that a completed discrete problem may serve a reinforcing stimulus.     

Preterm newborn pain research review

This narrative review is based on a literature search of PubMed and PsycINFO for research on preterm newborn pain published during the last ten years. The high prevalence of painful procedures being performed with preterm newborns without analgesia (79%), with a median of 75 painful procedures being received during hospitalization and as many as 51 painful procedures per day highlights the importance of this problem. This review covers the pain assessments that have been developed, the short-term effects of the painful procedures, the longer-term developmental outcomes and the pharmacological and alternative therapies that have been researched. The most immediate effects reported for repeated painful procedures include increased heart rate, oxidative stress and cortisol as well as decreased vagal activity. Lower body weight and head circumference have been noted at 32 weeks gestation. Blunted cortisol reactivity to stressors has been reported for three-month-olds and thinner gray matter in 21 of 66 cerebral regions and motor and cognitive developmental delays have been noted as early as eight months. Longer-term outcomes have been reported at school age including less cortical thickness, lower vagal activity, delayed visual– perceptual development, lower IQs and internalizing behavior. Pharmacological interventions and their side effects and non-pharmacological therapies are also reviewed including sucrose, milk and nonnutritive sucking which have been effective but thought to negatively affect breast-feeding. Full-body interventions have included tucking, swaddling, kangaroo care and massage therapy. Although these have been effective for alleviating immediate pain during invasive procedures, research is lacking on the routine use of these therapies for reducing long-term pain effects. Further, additional randomized controlled replication studies are needed.     

Juvenile prostitution and community rehabilitation: an exploratory analysis of beliefs and values

A community, juvenile prostitution rehabilitation programme in Bogotá, Colombia, South America is described; and beliefs and values of the residents were explored. Multiple sorting procedures and multi‐dimensional scaling analysis elicited qualitative, structured, self‐report data, and investigated cognitive constructs. Participants discriminated between belief‐statements along two global dimensions: street‐life and prostitution; and rehabilitation. These were comprised of qualitatively different elements. Clinical implications for interventions with this group and the rehabilitation programme are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Termination of logic programs with imperfect information: applications and query procedure

A general logic programming framework allowing for the combination of several adjoint lattices of truth-values is presented. The language is sorted, enabling the combination of several reasoning forms in the same knowledge base. The contribution of the paper is two-fold: on the one hand, sufficient conditions guaranteeing termination of all queries for the fix-point semantics for a wide class of sorted multi-adjoint logic programs are presented and related to some well-known probability-based formalisms; in addition, we specify a general non-deterministic tabulation goal-oriented query procedure for sorted multi-adjoint logic programs over complete lattices. We prove its soundness and completeness as well as independence of the selection ordering. We apply the termination results to probabilistic and fuzzy logic programming languages, enabling the use of the tabulation proof procedure for query answering.     

An evaluation of in vivo desensitization and video modeling to increase compliance with dental procedures in persons with mental retardation

Fear of dental procedures deters many individuals with mental retardation from accepting dental treatment. This study was conducted to assess the effectiveness of two procedures, in vivo desensitization and video modeling, for increasing compliance with dental procedures in participants with severe or profound mental retardation. Desensitization increased compliance for all 5 participants, whereas video modeling increased compliance for only 1 of 3 participants.     

认知压力与建构主义数学教学的关系

与通常在消极意义上使用的“精神压力”概念不同,“认知压力”是学习环境促使学习者进行不同类型认知活动的积极力量。根据这种环境导致学习者使用一级还是二级程序性知识达成目标,可将认知压力分成一级认知压力和二级认知压力。本研究以325名小学高年级和初中一二年级学生为被试,采用问卷法考察了数学课堂上认知压力的现状及其与建构主义教学的关系。结果表明：（1）对于数学课堂而言,被试报告的一级和二级认知压力处于中等偏上水平,而且二级认知压力显著高于一级认知压力;（2）建构主义数学教学有助于产生认知压力,特别是二级认知压力;（3）修订后的认知压力问卷有良好的信度和效度。
