Assessing complex problem-solving skills with multiple complex systems

In this paper we propose the multiple complex systems (MCS) approach for assessing domain-general complex problem-solving (CPS) skills and its processes knowledge acquisition and knowledge application. After defining the construct and the formal frameworks for describing complex problems, we emphasise some of the measurement issues inherent in assessing CPS skills with single tasks (i.e., fixed item difficulty, low or unknown reliability, and a large impact of random errors). With examples of the MicroDYN test and the MicroFIN test (two instances of the MCS approach), we show how to adequately score problem-solving skills by using multiple tasks. We discuss implications for problem-solving research and the assessment of CPS skills in general.     

Residual Normality Assumption and the Estimation of Multiple Membership Random Effects Models

While conventional hierarchical linear modeling is applicable to purely hierarchical data, a multiple membership random effects model (MMrem) is appropriate for nonpurely nested data wherein some lower-level units manifest mobility across higher-level units. Although a few recent studies have investigated the influence of cluster-level residual nonnormality on hierarchical linear modeling estimation for purely hierarchical data, no research has examined the statistical performance of an MMrem given residual non-normality. The purpose of the present study was to extend prior research on the influence of residual non-normality from purely nested data structures to multiple membership data structures. Employing a Monte Carlo simulation study, this research inquiry examined two-level MMrem parameter estimate biases and inferential errors. Simulation factors included the level-two residual distribution, sample sizes, intracluster correlation coefficient, and mobility rate. Results showed that estimates of fixed effect parameters and the level-one variance component were robust to level-two residual non-normality. The level-two variance component, however, was sensitive to level-two residual non-normality and sample size. Coverage rates of the 95% credible intervals deviated from the nominal value assumed when level-two residuals were non-normal. These findings can be useful in the application of an MMrem to account for the contextual effects of multiple higher-level units.     

Using Interdependent Group Contingencies with Randomly Selected Criteria and Paired Reading to Enhance Class-Wide Reading Performance

ABSTRACT

An intact second-grade class of 13 African-American students had completed few chapter-book reading assignments. A consultant worked with their teacher to develop an intervention that consisted of paired readings and two interdependent group contingencies. Following the implementation of the program, all students began reading chapter-books and the number of chapter-book quizzes passed increased from an average of less than 0.70 per week during baseline to 7.5 per week during the intervention phase. Discussion focuses on using interdependent group contingencies when targeting academic performance.     

Alarm Signals and Prompts to Eliminate Large Urinary Accidents in a Woman with Multiple Disabilities

Urine-triggered alarm signals and prompts were used to help a woman with multiple disabilities halt wetting episodes and walk to the toilet (thus avoiding large urinary accidents). Data indicated that the woman had a mean frequency of 1 large accident nearly every 2 days during the baseline phases and every 20 days during the intervention phases. During the latter phases, large accidents were replaced by small accidents (i.e. only a disposable tissue inside the underwear was wet), which did not cause environmental disruptions and did not require changes of clothes. Implications of the findings are discussed.     

Cognitive-Behavioural Treatment Package for Teaching Grooming Skills to a Man with an Intellectual Disability

A combination of health education, use of picture cues based on task analyses, a system of least prompts and social reinforcement was applied to teach various grooming skills to a man with a moderate intellectual disability. A multiple baseline design across behaviours was employed to show the effects. The results indicated rapid learning of lacking skills such as tooth brushing, shaving, showering and washing of arms and face.     

集体心理所有权、地位晋升标准与团队创造力

基于动机性信息加工理论, 本文首次实证探讨了集体心理所有权对团队创造力的影响机制。一项来自国内企业91个工作团队数据的统计分析发现, 集体心理所有权正向影响团队创造力; 信息深加工中介集体心理所有权与团队创造力的关系; 地位晋升标准显著性调节集体心理所有权与信息深加工之间的关系, 其中刻度型晋升标准增强集体心理所有权对信息深加工的正向影响, 而竞赛型晋升标准则减弱集体心理所有权对信息深加工的正向影响。     

A multi-informant study of the influence of targets’ and perceivers’ social desirability on self-other agreement in ratings of the HEXACO personality dimensions

In the current research we evaluated the impact of socially desirable responding on the strength of self-other agreement in personality judgments. We used a multi-informant design with self- and other-reports of HEXACO personality dimensions as well as self-reported and other-reported social desirability. Analyses were based on 305 primary participants and 709 informants. As shown by the results, neither self-other agreement nor other-other agreement regarding the personality dimensions was affected by social desirability. Furthermore, significant correlations between self-rated and other-rated social desirability emerged. The results are discussed as further evidence that most social desirability scales seem to measure substantive personality traits instead of response styles.     

Effects of Temporal Lobe Lesions on Retrograde Memory: A Critical Review

Scientific interest in retrograde memory has grown considerably over the last two decades. Studies have demonstrated that several brain regions, including the temporal lobes, participate in the formation, maintenance and storage of past memories. Different patterns and extents of retrograde memory deficits have been recorded in patients with temporal lobe lesions. It has been argued that the pattern of retrograde memory deficits is determined not only by the side and specific location of lesion within this region, but also by methodology, medical variables (such as etiology or seizure history), and coexisting cognitive deficits. In this paper we will review published case and group studies of patients with temporal lobe lesions to evaluate the impact of these factors on retrograde memory.     

Prototype awareness enhancing and monitoring device for trichotillomania

Trichotillomania is an impairing condition that involves repetitive hair pulling. Habit reversal therapy is helpful for many persons with this disorder. Unfortunately, habit reversal therapy is not helpful for everyone and maintenance of gains is often problematic. Successful habit reversal therapy requires the individual to be aware of hair pulling and handling. Unfortunately, most people with trichotillomania report that much of their plucking occurs outside of awareness. Monitoring of trichotillomania behaviors is also problematic. The present project involved a pilot study of a prototype awareness enhancing and monitoring device aimed at increasing the effectiveness of habit reversal therapy. The device included a watch, bracelet, magnetic necklace, and a pager that was hard-wired for remote activation of a vibrating alert when hair pulling behaviors occurred. Following structured diagnostic assessment, three female participants were randomly assigned to be initially observed for varied lengths of time without the device followed by observation with the device in place. The results indicated a marked reduction in trichotillomania behaviors when the device was in place. Semi-structured interviews revealed that the device was very effective in enhancing awareness and monitoring of trichotillomania related behaviors and enthusiastic acceptance of the device was provided by all participants.
