Evidence and Inference

I articulate a functional characterisation of the concept of evidence, according to which evidence is that which allows us to make inferences that extend our knowledge. This entails Williamson's equation of knowledge with evidence.     

A Method for Universal Screening of Elementary School Students: Development of the Social Challenges Screening Questionnaire

Schools regularly screen students for hearing and vision impairments because they present impediments to academic progress. For the same reason, schools should consider adding a universal screening for social challenges, which may also impede the learning process. This study reports on the development of the Social Challenges Screening Questionnaire (SCSQ), an efficient teacher-report screening questionnaire that identifies students with challenges who may benefit from a psychological evaluation. Further, the questionnaire may help identify students with Autism Spectrum Disorder who were previously undiagnosed. The SCSQ was administered to 549 general education students in the third and fourth grades. Internal consistency was.85. A smaller sample of students (n = 50) was selected for additional follow up assessment using the Social Responsiveness Questionnaire, Second Edition. Scores on the two instruments were strongly correlated (r =.87, p <.01), and sensitivity (.94) and specificity (.88) indicate the SCSQ can efficiently detect students with social challenges in need of a formal evaluation.     

A Below‐Average Effect with Respect to American Political Stereotypes on Warmth and Competence

The “above‐average effect” is the phenomenon that people tend to judge themselves above average on desirable traits. Based on social identity theory, we propose that a “below‐average effect” may arise when individuals rate themselves and the average ingroup member on traits stereotypically associated with the ingroup. In two studies, Republican and Democrat participants rated themselves and the average political ingroup member on possession of desirable traits related to warmth and competence. Current political stereotypes in America associate the former dimension with Democrats and the latter with Republicans. Consistent with our hypothesis, the above‐average effect was moderated by political group and dimension in interaction. In particular, Democrats rated themselves below the average Democrat on warmth and Republicans rated themselves below the average Republican on competence.     

“Reading” Paintings: Evidence for Trans-Symbolic and Symbol-Specific Comprehension Processes

Art-based reading instruction and interventions for elementary and middle school students are growing in popularity despite scant theoretical rationale and empirical research support. This study explored the degree to which painting comprehension processes map onto text comprehension processes in this population. In particular, we used think aloud protocols to examine the painting comprehension processes used by 35 fourth-grade and 34 eighth-grade students and compared the manifest processes to the literature on text comprehension. Protocol analysis revealed six painting comprehension processes—observing, activating prior knowledge, inferring and interpreting, elaborating, evaluating and responding, and monitoring—comprising 23 subprocesses. Of the identified painting comprehension subprocesses, 17 are commonly associated with text comprehension. These findings suggest that compositions—be they encoded visually, linguistically, or in another symbol system—may entail comprehension processes that transcend symbol systems, as well as processes that are particular to a given symbol system.     

The importance of autonomy support and the mediating role of work motivation for well‐being: Testing self‐determination theory in a Chinese work organisation

We examine relations between perceived organisational autonomy support and different types of work motivation and well‐being outcomes in 266 teachers from two government schools in China. We hypothesised that greater autonomy support would be associated with more autonomous forms of employee motivation, and that teacher motivation would in turn mediate the effects of autonomy support on indicators of work well‐being (i.e., job satisfaction, work stress and physical ill symptoms). Results generally supported the hypothesised relations between perceived autonomy support and SDT's five types of motivations. Findings also showed that perceived autonomy support predicted job satisfaction directly and indirectly through the mediating roles of intrinsic motivation, identified regulation, introjected regulation and external regulation. Perceived autonomy support predicted work stress directly and indirectly through the mediating roles of external regulation and amotivation. Autonomy support also predicted illness symptoms via the mediating roles of intrinsic motivation, introjected regulation and amotivation. The current findings highlight how perceived organisational support for autonomy relates to motivational differences in a Chinese work context, and the potential relevance of autonomy support for employee well‐being.
