Blending Theory with Practice: Implementing Kindergarten Transition Using the Interactive Systems Framework

The Interactive Systems Framework (ISF; Wandersman et al. in Am J Commu Psychol 41(3–4):171–181, 2008) was used to implement a kindergarten transition demonstration project collaboratively developed by elementary and early education providers, community‐based family and housing services, parents, and a University intermediary and technical assistance group. First person accounts from stakeholders at all levels provide a complementary and broad perspective on the project's implementation. The practice model blended existing research on kindergarten transition and parent involvement with feedback from stakeholders to create a community‐specific program designed to help all children make a smooth entry into kindergarten. During implementation, evidence‐based approaches needed to be adjusted to fit the specific needs of each community. Using the ISF as a guide, next steps and lessons learned include increasing leadership through a district‐wide plan that is still flexible within each school community, increasing information and supports to individual schools, and improving data collection for continuous program improvement.

Perceived Changes in Well-Being Following Polysaccharide Intake in Middle-Aged Adults

There is increased scientific interest in the effects of nutrition on cognition and well-being. Plant sourced polysaccharides play multiple roles in the biological processes required for health and well-being. This study explored the subjective experiential reports of well-being following intake of a plant derived polysaccharide supplement. The study used a 12 week double-blind, placebo controlled polysaccharide supplementation design. 109 middle-aged adults (45–60 years) took a standardised teaspoon of a combination of plant polysaccharides or a placebo twice daily for 12 weeks (3.6 g per day), and completed three, open-ended interviews at weeks 4, 8 and 12. Participants who took the polysaccharide supplement reported significantly more perceived beneficial changes in both physical and psychological well-being, specifically at week 12, compared to those who received the placebo. This study provides a starting point for understanding the perceived beneficial impact of polysaccharide interventions on aspects of well-being. Importantly, as a health-related application of polysaccharide science, this research supports the relationship that is emerging between the properties and function of polysaccharides. It is essential that future research assesses the effects of polysaccharide intake on a range of physical and psychological well-being outcomes to further the understanding of structure-function relationships with the aim of enhancing the functional health and well-being of individuals.     

Demand characteristics and research into drug use

Abstract

Health research makes frequent use of verbal reports; and such reports are usually assumed to be the surface indicants of measurable entities such as attitudes, beliefs, intentions, etc. which reside inside the person. It is our assertion that verbal reports themselves are motivated and variable; they are functional and context-dependent and their meaning and significance are localised. Consequently discourse cannot be treated as if it were fixed and categorical data to be retrieved from memory by asking questions that appear objective or disinterested. A method is postulated, using a social perception analogy with signal detection (SD) theory. The method allows for the assessment of subject criterion, and permits an examination of signal-strength in terms of the researcher's motivation. Data are evaluated in terms of their “robustness”, a measure which derives from the variability of response in different contexts, and under different elicitation procedures. The method requires few assumptions to be made about the “truth” or “falsity” of verbal reports. It focuses on the types of social activities that are performed by utterances and thus on the contextual variability revealed by asking questions in different situations and in different ways. This procedure does not presume a direct correspondence between verbal reports and mental representations.     

The Seven-Item Short Form of the Dyadic Adjustment Scale: Further Evidence for Construct Validity

Two studies examine psychometric aspects of the seven-item version of the Dyadic Adjustment Scale (DAS) (Spanier, 1976). In Study 1, data from 148 heterosexual clients seeking marital therapy services and 122 heterosexual couples in the community were used to assess the criterion validity of the DAS-7. The measure differentiated between clinic and community participants and between marriages classified as distressed or adjusted based on the full DAS score. In Study 2, the reliability and convergent validity of the DAS7, when administered as a separate scale, was assessed in a community sample of 162 participants who were married or were in cohabiting heterosexual relationships. Obtained values were comparable to those reported in previous research in which the DAS-7 was obtained by extracting items from participants' full DAS. These results demonstrate that the DAS-7 is a psychometrically sound short form for assessing marital adjustment.     

In defence of the concept of ‘spiritual education’: a reply to Roger Marples

In a paper published in Volume 11, no. 2, of this journal, Roger Marples argued that the term ‘spiritual education’ is at most superfluous and at worst entirely meaningless. He suggested that the use of the term is unhelpful and will continue to be so unless and until we can identify some body of spiritual knowledge and understanding, linked to experience, which is distinct from, and in some sense ‘beyond’, those of moral, aesthetic and other forms of experience.

This paper critique's Marples's thesis. It examines his ploy of admitting only certain forms of knowledge and understanding, and of privileging certain languages, when determining the rules of engagement with the concept of ‘the spiritual’. It is further argued that to require some empirical evidence in the form of personal experience before the words ‘spiritual’ and ‘spiritual education’ can be meaningful is fundamentally misguided. In conclusion, it is suggested that a willingness to embrace the spiritual as concept, experience and awareness is essential to the education of the child as a whole person.     

Accuracy of effect size estimates from published psychological research

A Monte-Carlo simulation was used to model the biasing of effect sizes in published studies. The findings from the simulation indicate that, when a predominant bias to publish studies with statistically significant results is coupled with inadequate statistical power, there will be an overestimation of effect sizes. The consequences such an effect size overestimation will then have on meta-analyses and power analyses are highlighted and discussed along with measures which can be taken to reduce the problem.     

Development of Phonological Constancy: Toddlers' Perception of Native- and Jamaican-Accented Words

ABSTRACT— Efficient word recognition depends on detecting critical phonetic differences among similar-sounding words, or sensitivity to phonological distinctiveness , an ability evident at 19 months of age but unreliable at 14 to 15 months of age. However, little is known about phonological constancy , the equally crucial ability to recognize a word's identity across natural phonetic variations, such as those in cross-dialect pronunciation differences. We show that 15- and 19-month-old children recognize familiar words spoken in their native dialect, but that only the older children recognize familiar words in a dissimilar nonnative dialect, providing evidence for emergence of phonological constancy by 19 months. These results are compatible with a perceptual-attunement account of developmental change in early word recognition, but not with statistical-learning or phonological accounts. Thus, the complementary skills of phonological constancy and distinctiveness both appear at around 19 months of age, together providing the child with a fundamental insight that permits rapid vocabulary growth and later reading acquisition.     

Homeless women and their families: Characteristics,life circumstances,and needs

This study investigated the needs of a sample of 100 women from shelters for the homeless in Richmond, Virginia. The women's responses to a 117-item interview were used to obtain information regarding their domicilary status, work history, educational background, family and health history, social support, reasons for homelessness, and social service needs. The results indicated that a significant number of the women had moved as many as six times within the past five years for various reasons, including domestic violence, interpersonal conflict, overcrowding, and eviction. Many women were high school graduates and had job skills in the health care, educational, and clerical fields. Most women were raised by their natural or extended family and the majority of them had a friend or family member who provided social support. Identified needs included housing, food, clothing, and transportation. The needs of homeless women and their children were different from the needs of the homeless chronically mentally ill and require specialized services as well as an increase in the available number of low-income housing units.     

Disrupting the conditioned stimulus preexposure effect in flavor-aversion learning: effects of interoceptive distractor manipulations

Rats exposed to a flavor prior to a conditioning trial involving that stimulus learn a significantly diminished flavor aversion relative to nonpreexposed control animals. A series of four experiments investigated the ability of the conditioned stimulus (CS) preexposure effect to be disrupted by the introduction of a distractor flavor stimulus between the preexposure and conditioning episodes. Experiment 1 demonstrated that the preexposure effect could be reduced by a distractor presented immediately following the preexposure. In Experiment 2, it was discovered that a novel distractor was more effective than a familiar distractor, even though both stimuli were sensorily equivalent. Experiment 3 further analyzed the distractor effect and demonstrated that the magnitude of disruption was more pronounced with immediate than with delayed (3 hr) distractor manipulations. Finally, Experiment 4 assessed the effects of the distractor in the absence of CS preexposure. The relation of the results from these experiments to general information theory is discussed.
