Infant Proneness-to-Distress Temperament, Maternal Personality, and Mother-Infant Attachment: Associations and Goodness of Fit

66 mother-infant pairs were examined when the infants were 9 and 13 months. The purpose of this report was to examine relations between infant proneness-to-distress temperament, maternal personality characteristics, and mother-infant attachment. There were no main-effect relations between infant proneness-to-distress temperament as assessed at 9 months and infant attachment classification at 13 months. This was true whether security of attachment (A and C vs. B) or proposed temperament (A1-B2 vs. B3-C2) groupings of attachment classifications were examined. Infant proneness-to-distress temperament, however, was associated with maternal behavior and personality. Furthermore, security of attachment could be predicted by an interaction between maternal personality and infant proneness-to-distress. The importance of considering goodness-of-fit relations in predicting attachment security is discussed.     

Second-order conditioning: Different outcomes in fear and eyelid conditioning

Second-order conditioning has been frequently observed with the fear response but not with the eyelid response. The present experiments manipulated the temporal relationship between the second-order and first-order stimulus on second-order conditioning trials. Our results indicated that a trace second-order procedure is not effective with either response system. Second-order fear conditioning was most prominent when the second-order CS terminated at the onset of the first-order CS. This arrangement, however, did not produce second-order eyelid CRs. In eyelid conditioning, the second-order CS appears to inhibit responding to the first-order CS which immediately follows it.     

Let the (Board) Games Begin: Creative Ways to Enhance Teaching and Learning

Gaming, in its many forms, is becoming a more active force in classrooms. To prepare preservice candidates for this trend, one teacher education program asked candidates (n = 60) to develop games in varied curricular fields tied to curriculum standards. This article describes the development of a model game, assignment requirements, provides a content review of eight games (geography and novels), their features, and highlights benefits and lessons learned from this experience.     

Faculty Learning Matters: Organizational Conditions and Contexts that Shape Faculty Learning

This study explored the relationships between faculty scholarly learning, faculty teaching learning, institutional support, faculty demographics, disciplinary groups, working conditions, and career outcomes such as retention, productivity, satisfaction, and career agency. We found that the stronger the scholarly learning faculty members reported, the more institutional and unit support they perceived for learning, the more satisfied they were, the less likely they were to intend to leave their institution, and the more career agency they reported. Similarly, we found that faculty members who reported more learning related to teaching reported a decreased intent to leave the institution and increased career agency. We draw implications for the development of work environments that support scholarly and teaching learning.     

Changing roles and identities in the construction of a community of mathematical inquiry

In the current shifts in mathematics classrooms, teachers are challenged to use effective pedagogy to develop inquiry communities in which all participants are offered opportunities to engage in the reasoning discourse of proficient mathematical practices. The challenge for teachers is to know how to implement these pedagogical changes. This article outlines how a teacher and researcher worked together in a collaborative partnership using a purposely designed communication and participation framework as a tool to scaffold development of collective reasoning in the inquiry community. The findings illustrate the interconnections between the teacher’s beliefs, past experiences, and current, and future expectations for her diverse students. Explanations are provided of how different, often conflicting, voices emerged including one that drew on the teacher’s cultural knowledge. This provided many learning opportunities for the researcher as the teacher developed her students’ voices in culturally appropriate ways.     

Relationship between performance-based and laboratory tests for lower-limb muscle strength and power assessment in healthy older women

Abstract

The aim of the study was to assess the relationship between performance-based and laboratory tests for muscular strength and power assessment in older women. Thirty-two women aged 68.8 ± 2.8 years were recruited. All participants were asessed for: (a) two performance-based tests – the box-stepping test (mean 296 ± 51 J) and two-revolution maximum test (mean 7.1 ± 2 kg) performed while pedalling on a cycle ergometer; and (b) muscular function tests – maximal instantaneous peak power jumping on a force platform (mean 1528 ± 279 W); maximal voluntary contraction (MVC) during knee extension (mean 601 ± 571 N) and leg press (mean 626 ± 126 N), and leg press power (mean 483 ± 98 W) on a dynamometer. Using univariate analysis, performance-based tests were compared with laboratory muscle strength and power measurements. Muscle power correlated most strongly with the performance-based tests for both jumping and leg press power (r-values between 0.67 and 0.75; P < 0.01). The correlation with muscle strength measures ranged between 0.48 and 0.61 (P < 0.01). The proposed tests may have particular relevance in geriatric and rehabilitation environments as they represent an easy, practical, and inexpensive alternative for the assessment of muscular strength and power.
