Development of manipulatory skills and the deployment of attention

Two independent tasks, object manipulation and auditory-visual matching, were used to examine the relationship between developing manual action skills and attention to intermodal object properties in 3.5- and 5.5-month-olds. Although handling skills improved with age, with older infants demonstrating more varied manipulation, there were no age differences for the matching task. When grouped by handling skills, a significant interaction between skill and event type was found for the two age groups combined and for 5.5-month-olds alone. Auditory-visual matching of social events did not vary with handling skills, whereas auditory-visualmatching of object events did. Infants at higher skill levels responded similarly to social and object events, whereas less skilled infants' matching preferences were weaker for object events. These findings indicate that infants increase their attention to auditory and visual properties of objects as this information becomes useful for guiding new actions. This effect is independent of age due to considerable individual variability in the development of object handling skills.     

Psychometric properties of the Wolpe-Lazarus assertiveness scale with community-dwelling older adults

The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were examined with an older community-dwelling, nonclinical, adult population. Three hundred twenty-seven older adults (ages, 57–96; mean, 75.68) who were not psychiatrically impaired completed a demographic questionnaire and the WLAS. Fifty-seven of the 327 subjects also filled out the WLAS on a repeated basis after 3 or 4 weeks in order to determine the test-retest reliability. Results indicate that the WLAS has an adequate internal consistency (Cronbach's=.75) and test-retest reliability (r=.81). WLAS cutoff scores of 14 and under identify unassertiveness. Older adults who are (1) African-American or (2) of lower SES tend to be significantly less assertive. Also, five factors emerged from a principal-components analysis accounting for 34.7% of the total variance.This research is based on the senior author's doctoral dissertation in partial fulfillment of the Ph.D. under the direction of the second, third, and fourth authors.     

REALISM AND OPENNESS IN SCIENTIFIC INQUIRY

Abstract. Intrinsic to rigorous knowledge of God is the recognition that positive theological concepts and statements about God arising under the compelling claims of God's reality upon the human mind must have an open revisable structure. A similar combination of critical realism and ontological openness is apparent in the profound change that has taken place in the rational structure of rigorous science from the radical dualism and closed causal system of classical mechanics to the unifying world view and open dynamic field-theories of modern physics. It is argued that the intersection of theological and natural science in their epis-temological foundations can enhance their ontological commitment and heuristic thrust.     

Rolston, Lonergan, and the Intrinsic Value of Nature

In recent metaethical debate over ways to justify the notion of intrinsic natural value, some neopragmatists have challenged realist conceptions of scientific and moral truth. Holmes Rolston defends a critical-realist epistemology as the basis for a metaphysics of projective nature and a cosmological narrative—both of which set up a historical ontology of objective natural value. Pure ecological science informs the wilderness experience of Rolston's ideal epistemic subject, the sensitive naturalist. The author argues that Rolston's account of the relation between knowing and valuing can be clarified and strengthened by appropriating Bernard Lonergan's transcendental method. Conversely, Lonergan's view of moral self-transcendence can be developed further in light of Rolston's virtue epistemology, which is embodied in the figure of the sensitive naturalist.

Do teacher instructional practices shape children's academic self-concept and interest in mathematics and science? Evidence from TIMSS 2015

Children possess different beliefs regarding their ability to succeed in math and science, as well as different levels of enjoyment and interest in these topics. These motivational processes are important because they often shape learning-related behaviours which in turn predict academic outcomes, over and above previous performance. But, what are the potential sources of influence that could explain individual differences in children's academic self-concept and interest in math and science? In this registered report, we adopted a situated expectancy-value theory framework to examine the potential role of teacher instructional practices that emphasize conceptual understanding in enhancing these motivational processes. We focused on practices emphasizing conceptual understanding given science-driven recommendations to implement them across the United States. Contrary to our hypotheses, a multilevel analysis of grade 4 U.S. data from the 2015 release of the Trends in International Mathematics and Science Study (TIMSS) revealed that the self-reported frequency of instructional practices emphasizing conceptual understanding were unrelated to math or science self-concept and interest. Our null findings prompt greater attention to other factors, such as the quality and implementation of instructional practices, differences between instructional goals and actual practices, and classroom composition, that could enhance ability beliefs and values in math and science.     

Continuous visual properties of number influence the formation of novel symbolic representations

Numerical symbols are thought to be mapped onto preexisting nonsymbolic representations of number. A growing body of evidence suggests that nonsymbolic numerical processing is significantly influenced by the associated visual properties of continuous quantity (e.g., surface area, density), but their role in the acquisition of novel symbols is unknown. Forty undergraduate students were trained to associate novel abstract symbols with numerical magnitudes. Half of the symbols were associated with nonsymbolic arrays in which total surface area and numerosity were correlated (“congruent”), and the other symbols were associated with arrays in which total surface area was equated across numerosities (“incongruent”). As numbers are represented in multiple formats (words, digits, nonsymbolic arrays), we also tested whether providing auditory nonword labels facilitated symbol learning. Following training, participants engaged in speeded comparisons of the newly learnt symbols. Comparisons were affected by the ratio between the numerosities associated with each symbol, a characteristic marker of numerical processing. Furthermore, comparisons were hardest for large-ratio comparisons of symbols associated with incongruent area and numerosity pairing during learning. In turn, these findings call for the further investigation of visual parameters on the development of numerical cognition.     

A bioinspired model of short-term satiety of hunger influenced by food properties in virtual creatures

The behavior of the human is continually changed as a consequence of various drives which human is predisposed also of your survival instinct. Among the basic drives of the human, there are the physiological needs and is precisely the hunger that motivates the food intake to get the energy that the body requires via food. The regulation of hunger allows to stop the food intake by means of the homeostatic and hedonic control which are influenced by the food properties. The process that consists of ending the food intake is known as short-term satiety and is important because it limits the amount of food intake; Otherwise, an over-consumed affect the organism functioning negatively. In this paper, we propose a conceptual model for the generation of short-term satiety behaviors based on neuroscientific evidence for virtual creatures. The conceptual model proposed is implemented in a distributed system-a virtual creature endowed with this implementation is placed in a virtual environment to analyze its behavior. The analysis shows how the virtual creature modifies its hunger level (behavior) based on food’s properties. The results show the execution of the process when the creature interacts with the environment.     

Reliability and acceptability of web-based administration of Spanish ages and stages questionnaires third edition®

to analyse the reliability of 6 age intervals of Spanish web-based Ages and Stages Questionnaires Third Edition (WB-ASQ-3) and parents' acceptability, in a clinical practice context, during COVID-19 pandemic and lockdown in Chile. Cross-sectional study with a longitudinal component. Internal consistency was analysed by Cronbach's alpha and Pearson product–moment correlation, Pearson's correlations between intervals questionnaires were analysed. Acceptability was determined using a parental satisfaction survey. 1061 children completed 2318 validated questionnaires. Scores were compared with normative sample, except for Gross motor at 8 and 12 months, and Communication at 12, 18 and 24 months, without differences to the previous Chileans sample. In domain analysis, Cronbach's alpha ranged from 0.36 to 0.80 and reached 0.74 to 0.81 for the overall test. Strong positive correlation between the domain and overall score was obtained. Correlation between most questionnaires at different ages was positive and significant. Parental surveys show high satisfaction; parents were thankful for being able to monitor children's development. WB-ASQ-3 is a reliable and feasible screening system, particularly when the test is taken as a whole, rather than by domains. It is remarkably high acceptability among parents, especially in complex times such as the lockdown and the COVID-19 pandemic.
