The utility and accuracy of oral reading fluency score types in predicting reading comprehension

This study used data from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) oral reading fluency (ORF) probes to examine variation among different ORF score types (i.e., the median of three passages, the mean of all three passages, the mean of passages 2 and 3, and the score from passage 3) in predicting reading comprehension as a function of student reading fluency level and to compare the screening accuracy of these score types in predicting student reading comprehension. The results revealed that the relation between oral reading fluency and reading comprehension varied as a function of students' oral reading fluency and that different score types had varying predictive validity for year-end reading comprehension. The mean of all three passages demonstrated a marginally better balance in screening efficiency from September to December of grade one (especially for low-performing students), whereas in grades two and three, the median score was the best predictor. Furthermore, across all grades, increasing reading rates were observed for the three administered passages within an assessment period. The observed patterns mimicked previous experimental studies (Francis et al., 2008; Jenkins, Graff, & Miglioretti, 2009), suggesting that practice effects are an important consideration in the administration of multiple passages assessing oral reading fluency.     

Silicon in ‘pure gold’? Theoretical contributions and observations on teleanalysis by videoconference

Ideas about psychoanalysis via videoconference—videoconference teleanalysis (VT)—are presented with the general understanding that these settings produce a twofold split between various degrees of recognition/negativisation of the absence of the other, on one hand, and the expectation of physical co‐presence, on the other. This split has been put forward as dismantling the here, now, with me pre‐reflexive unity of the analytic experience. This article suggests that both members of the analytic dyad will seek to reappropriate the experience through a forced ego integration that interferes with accessing states of unintegration in the analytic treatment and produces subtle alterations to symbolisation work. The effort to overcome this condition is illustrated with clinical vignettes and therapists’ comments about feelings of inauthenticity and discontent when trying to sustain evenly‐suspended attention, as well as in the perception of a form of flattening of the alive nature of speech. However, this is not a constant for all VT, and mutual understanding can be an important mitigating feature. The focus of the discussion should be on the capacity of the analytic dyad to overcome such a split and not on a direct extrapolation of the perceptual limitations of VT to possible effects on transference / countertransference.     

Speed and Rhythm Affect Temporal Structure of Variability in Reaching Poststroke: A Pilot Study

Temporal structure reveals the potential adaptive strategies employed during upper extremity movements. The authors compared the temporal structure of upper extremity joints under 3 different reaching conditions: preferred speed, fast speed, and reaching with rhythmic auditory cues in 10 individuals poststroke. They also investigated the temporal structure of these 3 reaching conditions in 8 healthy controls to aid in the interpretation of the observed patterns in the poststroke cohort. Approximate entropy (ApEn) was used to measure the temporal structure of the upper extremity joints. ApEn was similar between conditions in controls. After stroke, ApEn was significantly higher for shoulder, elbow, and wrist both at fast speed and with rhythmic cues compared with preferred speed. ApEn at index finger was significantly higher only with rhythmic cues compared with preferred speed. The authors propose that practice reaching at faster speed and with rhythmic cues as a component of rehabilitation interventions may enhance adaptability after stroke.     

Concurrent and longitudinal dyadic polynomial regression analyses of Big Five traits and relationship satisfaction: Does similarity matter?

Being with a well-matched partner seems essential for a happy relationship. However, past research on personality similarity in couples has reported inconsistent findings. The current study employs a dyadic polynomial regression approach to take into account linear and curvilinear associations between similarity and satisfaction. The concurrent results based on data of 237 couples suggest that beyond actor effects for neuroticism, agreeableness, and conscientiousness and partner effects for agreeableness, similarity plays a negligible role for relationship satisfaction. Longitudinally, two similarity effects emerged. First, if partners reported dissimilar neuroticism levels, male partner reported lower relationship satisfaction. Second, if both partners reported modest levels in openness, female partners reported higher relationship satisfaction. Implications for couples are discussed.     

A circle of traits: A perceptual mapping of the NEO-PI-R

The five factor model, a dominant model of personality today, is based on the pre-structuring of test-components and factor analytic (FA) interpretations. These procedures have been criticised, especially FA’s limitation to accurately identify the underlying structure of constructs. This paper examined whether the NEO-PI-R revealed the same trait structures when analysed through alternative statistical procedures. Non-metric multidimensional scaling (NMDS) was employed alongside FA techniques (N = 384). FA indicated the presence of five factors, but NMDS suggested a more parsimonious arrangement, comprising three (similar to Eysenck’s PEN model), or even two “super structures”. Furthermore, a circular trait arrangement was a reasonable alternative, suggesting that traits can be meaningfully (re)classified based on their kind and their integrative centrality. Over-reliance on FA models might not be the most appropriate approach for a better understanding of personality.     

试论骨科辐射效应的线性与非线性关系

放射界对于辐射效应一直沿用线性无阈理论,但近年来,低剂量辐射效应却让其表现出非线性特征。而且对于骨折以及骨科其他疾病来说不同剂量辐射所产生的效应是不同的,即其在骨科中也存在线性与非线性的对立统一,只有认清这两者的辩证关系,才能抓住其本质,最终产生深远的意义和临床应用。     

When should clinicians switch treatments? An application of signal detection theory to two treatments for women with alcohol use disorders

Statistical application of signal detection theory has been used to study the clinical utility of early treatment response in a range of treatments and psychiatric disorders. The current study sought to examine the predictive value of weekly within-treatment drinking using receiver operator curves (ROCs) and zero-inflated Poisson (ZIP) regression in 102 women with alcohol use disorders (AUDs) randomized to either alcohol behavioral individual treatment (ABIT; n = 52) or alcohol behavioral couples treatment (ABCT; n = 50). ROC analyses indicated that failure to achieve or sustain abstinence by the end-of-treatment and one-year follow-up was predicted with reasonable accuracy by week 4 percent days abstinent (PDA) in ABIT. ZIP models yielded similar results with evidence for within-treatment PDA with week 6 PDA predicting both the abstinence as well as percent days drinking at the end-of-treatment and one-year follow-up. Within-treatment PDA was a significantly better predictor of outcomes for ABIT than ABCT, despite a better overall treatment response for ABCT. Implications for stepped care models of alcohol treatment are discussed and recommendations for future research made.

线索呈现位置对概率类别学习的影响

当前概率类别学习中主要存在多系统和单系统两种观点之争, 而持不同观点的研究者在其实验中分别采用了不同的线索位置呈现方式, 因此本研究采用经典的天气预测任务通过操纵线索位置的呈现方式来进一步探讨其对概率类别学习的影响。本研究包括2个实验：实验1考察所有线索位置固定和随机对概率类别学习系统的影响; 实验2通过单线索模式下线索位置固定考察概率类别学习的策略。结果发现, 当所有线索的呈现位置固定时, 概率类别学习是外显学习; 而当所有线索的呈现位置随机时, 概率类别学习是内隐学习; 而当只在线索单独出现时固定其位置, 概率类别学习仍是内隐学习。结果表明, 线索位置的不同呈现方式会影响概率类别学习中外显和内隐学习系统的竞争, 研究支持了多系统观点, 且概率类别学习的主要策略可能是多线索策略而不是单模式策略。
