Competition during the processing of quantifier scope ambiguities: Evidence from eye movements during reading

We investigated the processing of sentences containing a quantifier scope ambiguity, such as Kelly showed a photo to each critic, which is ambiguous between the indefinite phrase (a photo) having one or many referents. Ambiguity resolution requires the computation of relative quantifier scope, with either a photo or each critic taking wide scope, thereby determining the number of referents. Using eye tracking, we established that multiple factors, including the grammatical function and surface linear order of quantified phrases, along with their lexical characteristics, interact during the processing of relative quantifier scope, with conflict between factors incurring a processing cost. We discuss the results in terms of theoretical accounts attributing sentence-processing difficulty to either reanalysis (e.g., Fodor, 1982) or competition between rival analyses (e.g., Kurtzman & MacDonald, 1993).     

Children’s sequential information search is sensitive to environmental probabilities

We investigated 4th-grade children’s search strategies on sequential search tasks in which the goal is to identify an unknown target object by asking yes–no questions about its features. We used exhaustive search to identify the most efficient question strategies and evaluated the usefulness of children’s questions accordingly. Results show that children have good intuitions regarding questions’ usefulness and search adaptively, relative to the statistical structure of the task environment. Search was especially efficient in a task environment that was representative of real-world experiences. This suggests that children may use their knowledge of real-world environmental statistics to guide their search behavior. We also compared different related search tasks. We found positive transfer effects from first doing a number search task on a later person search task.     

Fibromyalgia: Predicting openness to counselling referrals

Fibromyalgia (FM) is a chronic pain condition that can negatively impact on all aspects of patients’ lives. The purpose of this study was: first, to explore the biopsychosocial factors that may contribute to adjustment to FM symptoms; second, to investigate how referrals to counselling related to patients’ ratings of their relationship with their physicians; and, last, to examine if self-reports of illness distress, emotional problems, and practical problems can predict who will be open to counselling referrals. For this cross-sectional study, data from 190 people were collected through an online survey. Statistical analysis revealed that emotional problems reported were the best predictor of variance in illness distress and contentment scores. Further, results indicated that referrals made in accord with patients’ perceptions that they would benefit from counselling may have a positive influence on how patients rate their relationships with their physicians. Finally, self-reported scores of illness distress, number of emotional problems, and number of practical problems accurately predicted who would be open to counselling referrals in 67% of cases. Research results provide support for addressing emotional issues to facilitate adjustment to FM symptoms, and for use of psychosocial measures to determine when patients with FM will be open to counselling referrals.     

Predicting parental sunscreen use: Disentangling the role of action planning in the intention–behavior relationship

Structural equation modeling was used to examine antecedents of parental sunscreen use (N = 436) in a longitudinal design. The influence of a volitional planning cognition was assessed in several path models, investigating potential mediation and moderation of the intention–behavior relationship. Premotivational and motivational variables accounted for 55.1% of the variance in intention to use sunscreen. Intention emerged as the most powerful predictor of behavior, followed by action planning and self-efficacy expectations, together explaining 35.4% of parental sunscreen use after five months. Strong support was found for both mediating and moderating influences of action planning on the intention–behavior relationship. Action planning also partially mediated the impact of self-efficacy on behavior. The results support theoretical considerations to add postintentional cognitions to current health behavior models. Although action planning is an important component in the transition from intention to behavior, the impact of intention and of other premotivational and motivational variables should not be overlooked when developing health educational interventions.     

Changes over time from baseline poor self-rated health: For whom does poor self-rated health not predict mortality?

The aim of this study was to understand for whom and why poor self-rated health (SRH) is a less valid predictor of longevity or future health by examining the predictors of decline in health among people with poor baseline SRH. The sample included 409 participants in the Cross-Sectional and Longitudinal Study of the old–old (75+) in Israel, who were self-respondents and rated their health as poor at baseline and their status was known at follow-up 3.5 years later: deceased/moved to proxy interview/remained in poor SRH/or improved SRH. Baseline measures included self-reported medical status, physical, cognitive, psychological and social functioning. Findings showed that less decline in health was predicted by less difficulty in physical and cognitive functioning at baseline and by a more active physical and social life, after controlling for socio-demographics. Most of the predictors retained a unique contribution in a multivariate model, suggesting that engagement in meaningful activities serves as an indicator of better health and longer survival even within a group of old–old people in poor health. It may reflect greater social support, contribute to fitness and/or provide a sense of mastery, which could explain similar findings regarding gender and race/ethnicity groups for whom SRH is a less potent predictor of mortality.

Cluster formulae for alloy phases

Composition formulae for alloy phases are developed using first-neighbour coordination polyhedra plus their connections. The resultant cluster formulae [cluster](glue atom) _x , similar to molecular formulae for chemicals, contain key structural and composition information on the alloy phases. As examples, Al–Ni–Zr alloy phases are analysed with the objective of revealing cluster formula properties such as the principal cluster, the cluster phase and the definition of complex alloy phases.     

Microstructure and martensitic transformation behaviors of a Ti–Ni–Hf–Cu high-temperature shape memory alloy ribbon

The Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon undergoes a B2 ? B19′ transformation upon cooling and heating. When the Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon is annealed at 873 K for 1 h, the spherical (Ti, Hf)₂Ni particles with a diameter of 20–40 nm precipitate in the grain interior. The fine (Ti, Hf)₂Ni precipitates improve the stability of phase transformation temperatures and cause martensite domains, with (001) compound twins in three orientations dominant instead of (011) type I twins. {111}-, {113}- and (001)//{111}-type boundaries are observed among these martensite domains. When the (Ti,Hf)₂Ni precipitates coarsen, (011) type I twins become main martensite structures in the ribbon annealed at 973 K for 1 h.     

Microstructure evolution of Al-15% Si alloy during hot rolling

ABSTRACT

A direct chill (DC) cast Al-15% Si alloy was processed by hot rolling with a single pass at a temperature of 520°C with a thickness reduction of 80%. Scanning electron microscopy (SEM), electron backscattering diffraction (EBSD) and transmission electron microscopy (TEM) were used to investigate the evolution of the sample’s microstructure. After hot rolling, silicon particles homogeneously distributed in the Al matrix with fine equiaxed grains of average size ～ 0.95?μm. High-angle boundaries (HABs) (about ～75.8% in percentage) dominate in the Al matrix structure. There is evidence for Si-particle-stimulated continuous dynamic recrystallization (CDRX) during hot rolling.     

Mechanism of formation of aligned two-phase microstructure in a Fe-0.25wt%C alloy under high magnetic field gradients

The effect of a magnetic force on creating an aligned two-phase microstructure in a Fe-0.25wt%C alloy under magnetic field gradients has been investigated. Through the changes in the heating temperature, both dipolar interactions and magnetic forces work together during the austenite to ferrite transformation. The results showed that the aligned two-phase microstructure is not observed under the influence of the magnetic force alone. The ferrite grains are elongated due to dipole interactions at the early stages of their nucleation and growth and then the magnetic force turns the elongated ferrite grains, whose major axis is not parallel to the direction of magnetic force, to the direction of the field in the presence of magnetic field gradients.
