History Assessments of Thinking: A Validity Study

This article reports a validity study of History Assessments of Thinking (HATs), which are short, constructed-response assessments of historical thinking. In particular, this study focuses on aspects of cognitive validity, which is an examination of whether assessments tap the intended constructs. Think-aloud interviews with 26 high school students were used to examine the thinking elicited by 8 HATs and multiple-choice versions of these tasks. Results showed that although both HATs and multiple-choice items tapped historical thinking processes, HATs better reflected student proficiency in historical thinking than their multiple-choice counterparts. Item format also influenced the thinking elicited, with multiple-choice items eliciting more instances of construct-irrelevant reasoning than the constructed-response versions. Implications for history assessment are discussed.     

Psychometric Status and Clinical Utility of the MAYSI-2 with Girls and Boys in Juvenile Detention

This study replicates and extends studies of the Massachusetts Youth Screening Instrument, Version 2 (MAYSI-2) in a sample of 479 urban, rural, and suburban 12–16 year old youths (68% boys; 41% African American, 23% Latino) consecutively admitted to juvenile detention centers. Six principal components replicated the MAYSI-2 factor-analytically-derived subscales except for Depression/Anxiety, and suggested modifications of specific items in each sub-scale. Findings supported the internal consistency and validity of the modified MAYSI-2 sub-scales. Few gender differences emerged, except that girls reported higher levels of hopelessness and trauma than boys. Five sub-groups were identified based on component profiles: (1) non-clinical, (2) addiction, somatic problems, and suicidality, (3) anger problems, (4) thought disturbance, and (5) addiction and traumatic stress. The findings support the validity of the MAYSI-2 for juvenile justice mental health screening while highlighting possible refinements in scoring in order to identify delinquent youths with distinctive psychosocial risks and needs.     

社交焦虑个体对正性面孔刺激的解释偏差

本研究分别在短时（60ms）和长时（无时间限制）条件下呈现匹配的正性和中性面孔,要求高、低社交焦虑被试选择更具威胁性的面孔,以验证两者对正性刺激是否存在主观解释偏差,并考察该偏差产生于认知加工的哪一阶段。结果发现,长时条件下,高焦虑组选择正性面孔的比例显著高于低焦虑组;短时条件下无显著差异。提示高社交焦虑个体对正性刺激存在主观、外显的解释偏差,他们更倾向于对正性刺激做出消极解释,并且这种偏差产生于认知加工的后期。     

Daily Behavior Report Cards and Systematic Direct Observation: An Investigation of the Acceptability,Reported Training and Use,and Decision Reliability Among School Psychologists

More than ever, educators require assessment procedures and instrumentation that are technically adequate as well as efficient to guide data-based decision making. Thus, there is a need to understand perceptions of available tools, and the decisions made when using collected data, by the primary users of those data. In this paper, two studies that surveyed members of the National Association of School Psychologists with regard to two procedures useful in formative assessment, (i.e., Daily Behavior Report Cards; Systematic Direct Observation), are presented. Participants reported greater overall levels of training and use of Systematic Direct Observation than Daily Behavior Report Cards, yet both techniques were rated as equally acceptable for use in formative assessment. Furthermore, findings supported that school psychologists tend to make similar intervention decisions when presented with both types of data. Implications, limitations, and future directions are discussed.     

Preschool Behavioral and Emotional Rating Scale (PreBERS): Test–Retest Reliability and Inter-Rater Reliability

The Preschool Behavioral and Emotional Rating Scale (PreBERS) is a standardized, norm-referenced instrument that assesses the emotional and behavioral strengths of preschool children. Two studies that investigated the test–retest and inter-rater reliability of the PreBERS are reported. In the first study, teachers rated preschool children (N = 96) on two occasions with 1 month between ratings. Reliability coefficients for the four subscales and total score of the PreBERS were all at or above 0.86. In the second study teachers and paraprofessionals rated the same preschool children (N = 88). All of the correlations were over 0.72. In both studies the magnitude of correlations were large indicating that the PreBERS is a stable measure across time and raters. Based on the data the PreBERS appears to be a psychometrically sound instrument appropriate for use with preschool children. Recommendations for use with preschool children as well as future research are discussed.

Lose One Another ... and Find One Another in Nanospace. ‘Nanotechnologies for Tomorrow’s Society: A Case for Reflective Action Research in Flanders (NanoSoc)’

The main objective of the Flemish research project ‘Nanotechnologies for tomorrow’s society’ (NanoSoc) is to develop and try out an interactive process as a suitable methodology for rendering nanoresearchers aware of underlying assumptions that guide nanotech research and integrating social considerations into the research choices they face. In particular, the NanoSoc process should sustain scientists’ capacities to address growing uncertainties on the strategic, scientific and public acceptance level. The article elaborates on these uncertainties and involved dilemmas scientists are facing and proposes a process approach which addresses strategic uncertainty by alternating between ‘visioning’ and ‘technology assessment’; a process design which manages complexity by promoting reflexivity among scientists by exposing them to deliberations in civil society (social experts, stakeholders, citizens) on plausible futures with nanotechnologies; and as an answer to societal ambivalence, certain process quality requirements such as an attitude of perplexity or openness towards ‘plurality’ and an attitude of ‘temporary closure’, both in support of understanding and learning from differences.

A preliminary comparison of functional analysis results when conducted in contrived versus natural settings

A preliminary evaluation of the correspondence between functional analysis outcomes across settings was conducted with 2 children who had been diagnosed with autism and who engaged in challenging behavior. Differences across settings (a therapy room and a classroom) were demonstrated in ABAB reversal designs. Three potential patterns of results that may occur when comparing functional analyses across environments are described, and one possible explanation for the occurrence of discrepancies between environments (differing learning histories within separate environments) is offered.     

Distributed skill functions and the meshing of knowledge structures

The scope of knowledge space theory was extended by bringing into the picture the underlying skills and capabilities that are relevant to solving the problems in a knowledge domain. A major challenge to this approach comes from the need to aggregate distributed information on (partially) overlapping domains and skill sets. The notion of a distributed skill function is introduced for formalizing the integration of several skill functions that represent the assignment of skills to problems. It is shown that their consistency is captured by the meshability of the delineated knowledge structures. This result draws upon a characterization of the meshing of finite or infinite collections of knowledge structures, which extends and generalizes previous results on the binary case. The discussion covers implications for knowledge assessment and for practical applications, such as integrating skill assignments coming from different experts or distributed resources in technology-enhanced learning.     

Rapid acquisition of preference in concurrent chains: effects of d-amphetamine on sensitivity to reinforcement delay

The purpose of this study was to examine effects of d-amphetamine on choice controlled by reinforcement delay. Eight pigeons responded under a concurrent-chains procedure in which one terminal-link schedule was always fixed-interval 8 s, and the other terminal-link schedule changed from session to session between fixed-interval 4 s and fixed-interval 16 s according to a 31-step pseudorandom binary sequence. After sufficient exposure to these contingencies (at least once through the pseudorandom binary sequence), the pigeons acquired a preference for the shorter reinforcement delay within each session. Estimates of the sensitivity to reinforcement immediacy were similar to those obtained in previous studies. For all pigeons, at least one dose of d-amphetamine attenuated preference and, hence, decreased estimates of sensitivity to reinforcement immediacy; in most cases, this effect occurred without a change in overall response rates. In many cases, the reduced sensitivity to reinforcement delay produced by d-amphetamine resulted primarily from a decrease in the asymptotic level of preference achieved within the session; in some cases, d-amphetamine produced complete indifference. These findings suggest that a reduction in the sensitivity to reinforcement delay may be an important behavioral mechanism of the effects of psychomotor stimulants.
