Two are better than one: comparison influences infants' visual recognition memory

Despite a large literature on infants’ memory for visually presented stimuli, the processes underlying visual memory are not well understood. Two studies with 4-month-olds (N = 60) examined the effects of providing opportunities for comparison of items on infants’ memory for those items. Experiment 1 revealed that 4-month-olds failed to show evidence of memory for an item presented during familiarization in a standard task (i.e., when only one item was presented during familiarization). In Experiment 2, infants showed robust memory for one of two different items presented during familiarization. Thus, infants’ memory for the distinctive features of individual items was enhanced when they could compare items.     

Challenges Faced by Genetics Service Providers’ Practicing in a Culturally and Linguistically Diverse Population: An Australian Experience

This paper explores the perceived challenges facing clinical genetics practitioners in multicultural Australia. Focus groups conducted with 53 practitioners explored: 1) participants’ experiences and definitions of cultural diversity; 2) their use of educational resources with clients; 3) their experiences with culturally diverse groups/individuals in practice; 4) their experiences working with interpreters; and 5) the impact culturally specific educational training and/or experiential learning had on their confidence or practice when dealing with culturally diverse clients. Participants viewed culture as extending beyond traditional definitions such as ethnicity, language and religion. Most respondents had experienced positive results working with health care interpreters, although at times, this was a challenge for the family as they preferred privacy and the use of family members as interpreters. Another commonly reported challenge was the limited availability of reliable, culturally appropriate translated resources. Some participants expressed concern that learning theories about specific cultures may lead to stereotypes and that opportunities for formal cultural competence training were limited. Recommendations for practice include the targeting of educational resources to meet the needs of a diverse community and placing cultural competence on the agenda for ongoing training and maintenance of professional standards for clinical genetics practitioners to avoid the current ad hoc approach.     

关于严重突发事件危机干预的研究评述

对国外关于严重突发事件危机干预的研究作了概览与评述。认为有两点值得关注：其一,危机干预中的评估的重要性。在干预中,评估是进行干预的前提条件,更贯穿干预过程的始终。干预者必须通过不断评估确定危机的严重程度,不断确定当事人的心理状态,才能确定采用相应的应付策略和支持系统等。其二,国外许多不同的干预模式具有3个特征：一是阶段划分技术,将干预过程划分为不同的阶段,针对不同阶段的特点采取不同的措施与策略。二是整合倾向,将不同的干预模式、支持资源加以整合,使干预的效果达到最佳水平。三是特异性发展,即针对不同人群、不同应激情境作深度拓展,发挥干预的特异性效果。“非典”流行对我国的危机干预体系是一个严峻的考验,我国面对严重突发事件的危机干预体系还有待于健全。虽然不能照搬外国的干预模式,但是其思路与技术、经验与教训还是值得我们借鉴的。     

Gender-role orientations in older child-free and expectant couples

Psychosocial aspects of variant fertility decisions were investigated to determine factors that differentiate individuals who chose to become parents for the first time after age 30 and their peers who chose to remain child free. Forty women, aged 30 to 38, half of whom were child free and half expecting their first child, and 34 of their husbands were interviewed and completed the Role Questionnaire. The pattern of data suggests that the relatively traditional gender-role orientations of the expectant individuals may be an important factor that discriminates the two groups. The Rapoports' concept of “identity tension line” is used to integrate the results of the study and to explore findings that indicate different degrees of traditionalism in regard to work and family roles.     

Cross-Sectional Analysis of Longitudinal Mediation Processes

Statistical mediation analysis can help to identify and explain the mechanisms behind psychological processes. Examining a set of variables for mediation effects is a ubiquitous process in the social sciences literature; however, despite evidence suggesting that cross-sectional data can misrepresent the mediation of longitudinal processes, cross-sectional analyses continue to be used in this manner. Alternative longitudinal mediation models, including those rooted in a structural equation modeling framework (cross-lagged panel, latent growth curve, and latent difference score models) are currently available and may provide a better representation of mediation processes for longitudinal data. The purpose of this paper is twofold: first, we provide a comparison of cross-sectional and longitudinal mediation models; second, we advocate using models to evaluate mediation effects that capture the temporal sequence of the process under study. Two separate empirical examples are presented to illustrate differences in the conclusions drawn from cross-sectional and longitudinal mediation analyses. Findings from these examples yielded substantial differences in interpretations between the cross-sectional and longitudinal mediation models considered here. Based on these observations, researchers should use caution when attempting to use cross-sectional data in place of longitudinal data for mediation analyses.     

MEASURING REFLECTIVE SUPERVISION WITHIN HOME VISITING: CHANGES IN SUPERVISORS’ SELF‐PERCEPTION OVER TIME

Despite widespread belief in the early childhood field of the benefits of reflective supervision, there has been limited empirical evidence to support the effectiveness of reflective supervision for home visitors and the children and families they serve. The present study examined the psychometric properties of four adapted self‐report measures assessing supervisors’ reflective supervision capacities; the study also investigated whether these measures captured change in reflective capacity over time as supervisors participated in professional development activities focused on reflective supervision. Results from 33 participants (home visiting supervisors and program managers) suggested that three of the four measures demonstrated acceptable internal consistency, and these three measures were correlated with each other. Two of these measures also captured significant change over time. Finally, there was some evidence that those with less education demonstrated more substantial improvement in their reflective supervision capacities than did those with an advanced degree. Findings provide initial evidence for reliable, efficient, and cost‐effective supervisor self‐report measures that could be used in research and program evaluation to assess change in supervisor reflective capacity over time.     

Nonword repetition stimuli for Vietnamese-speaking children

Nonword repetition (NWR) has been a widely used measure of language-learning ability in children with and without language disorders. Although NWR tasks have been created for a variety of languages, minimal attention has been given to Asian tonal languages. This study introduces a new set of NWR stimuli for Vietnamese. The stimuli include 20 items ranging in length from one to four syllables. The items consist of dialect-neutral phonemes in consonant–vowel (CV) and CVC sequences that follow the phonotactic constraints of the language. They were rated high on wordlikeness and have comparable position segments and biphone probabilities across stimulus lengths. We validated the stimuli with a sample of 59 typically developing Vietnamese–English bilingual children, ages 5 to 8. The stimuli exhibited the expected age and length effects commonly found in NWR tasks: Older children performed better on the task than younger children, and longer items were more difficult to repeat than shorter items. We also compared different scoring systems in order to examine the individual phoneme types (consonants, vowels, and tones) and composite scores (proportions of phonemes correct, with and without tone). The study demonstrates careful construction and validation of the stimuli, and future directions are discussed.     

Detecting random responders with infrequency scales using an error-balancing threshold

Infrequency scales are becoming a popular mode of data screening, due to their availability and ease of implementation. Recent research has indicated that the interpretation and functioning of infrequency items may not be as straightforward as had previously been thought (Curran & Hauser, 2015), yet there are no empirically based guidelines for implementing cutoffs using these items. In the present study, we compared two methods of detecting random responding with infrequency items: a zero-tolerance threshold versus a threshold that balances classification error rates. The results showed that a traditional zero-tolerance approach, on average, screens data that are less indicative of careless responding than those screened by the error-balancing approach. Thus, the de facto standard of applying a “zero-tolerance” approach when screening participants with infrequency scales may be too stringent, so that meaningful responses may also be removed from analyses. Recommendations and future directions are discussed.
