Effects of Performance Criteria during Reading Instruction on Generalized Oral Reading Fluency

Although there is some evidence that setting performance criteria may improve oral reading fluency interventions, little is known about the generalized effects of these criteria. The present study trained two third‐grade students to three different fluency levels on instructional passages and assessed generalized performance in corresponding high word‐overlap passages within an alternating treatments design. Results indicated no discernable differences across experimental conditions. Follow‐up analyses revealed that generalized gains per trial were actually larger in lower criterion conditions, suggesting that performance criteria may not be as helpful as previously thought. The results are discussed in terms of the need to empirically investigate the number of instructional trials necessary to maximize instructional efficiency.

Truthier Than Thou: Truth,Supertruth and Probability of Truth

Different formal tools are useful for different purposes. For example, when it comes to modelling degrees of belief, probability theory is a better tool than classical logic; when it comes to modelling the truth of mathematical claims, classical logic is a better tool than probability theory. In this paper I focus on a widely used formal tool and argue that it does not provide a good model of a phenomenon of which many think it does provide a good model: I shall argue that while supervaluationism may provide a model of probability of truth, or of assertability, it cannot provide a good model of truth—supertruth cannot be truth. The core of the argument is that an adequate model of truth must render certain connectives truth‐functional (at least in certain circumstances)—and supervaluationism does not do so (in those circumstances).     

Motivating the academic mind: High-level construal of academic goals enhances goal meaningfulness,motivation, and self-concordance

How one thinks about or conceptualizes a goal has important consequences for the motivational features of goal pursuit. Two experiments tested the hypothesis, inspired by work on meaning in life, action identification theory, and expectancy-value theory, that high-level construal of an academic goal should enhance motivation to pursue that goal. In each experiment, we manipulated high-level versus low-level construal of an academic goal and assessed several variables related to the goal: the perceived meaningfulness of the goal, motivation to pursue the goal, and goal self-concordance. Supporting the hypothesis, individuals who thought about their academic goal in a high-level manner viewed their goal as more meaningful, reported being more motivated to pursue the goal, and reported the goal to be more self-concordant. Implications and future directions are discussed.     

Estimating the Mental Health Effects of Social Isolation

It is frequently hypothesized that feelings of social isolation are detrimental for an individual’s mental health, however standard statistical models cannot estimate this effect due to reverse causality between the independent and dependent variables. In this paper we present endogeneity-corrected estimates of the mental health consequences of isolation (based on self-assessed loneliness scores) using Australian panel data. The central identification strategy comes from a natural source of variation where some people within our sample are required by work or study commitments to move home. This relocation may break individuals’ social ties, resulting in significantly higher reported feelings of loneliness and consequently may lower mental health scores. The method gives results that are significant, robust and pass a battery of diagnostic tests. Estimates indicate that feelings of isolation have large negative consequences for psychological well-being, and that the effects are larger for women and older people. The results suggest that at current levels, a 10 % reduction applied to all individuals would reduce annual expenditure on mental illness in Australia by approximately $3B AUD, or around $150 AUD per person.
