A phonetic approach to consonant repetition in early words

The goal of this study was to evaluate movement-based principles for understanding early speech output patterns. Consonant repetition patterns within children's actual productions of word forms were analyzed using spontaneous speech data from 10 typically developing American-English learning children between 12 and 36 months of age. Place of articulation, word level patterns, and developmental trends in CVC and CVCV repeated word forms were evaluated. Labial and coronal place repetitions dominated. Regressive repetition (e.g., [gag] for “dog”) occurred frequently in CVC but not in CVCV word forms. Consonant repetition decreased over time. However, the children produced sound types available reported as being within young children's production system capabilities in consonant repetitions in all time periods. Findings suggest that a movement-based approach can provide a framework for comprehensively characterizing consonant place repetition patterns in early speech development.     

理性-经验加工对不公正情绪和行为反应的影响:公正敏感性的调节作用

基于认知-经验理论,采用行为实验法和情境故事法,探讨了不同信息加工方式对不公正情绪和行为反应的影响,以及受害者敏感性对两者关系的调节作用。结果表明,与理性加工相比,经验加工下个体对不公正有更强烈的负性情绪反应,合作意向更低;受害者敏感性调节加工方式与不公正行为反应之间的关系,即受害者敏感性低时,加工方式与人际公正对合作意向交互作用显著,受害者敏感性高时,加工方式与人际公正对合作意向没有交互作用。     

The Effect of Children's Sleeping Arrangements (Communal vs. Familial) on Fatherhood Among Men in an Israeli Kibbutz

Abstract

The author examined the effect of children's sleeping arrangements (communal vs. familial) on the extent of fathers' involvement in their children's lives and their level of satisfaction from fatherhood. Questionnaires assessing those aspects of fatherhood were administered to 40 fathers living in a kibbutz. Results indicated that the fathers of children sleeping at home were more involved with their children's lives and showed higher levels of satisfaction from fatherhood. Preference for a communal sleeping arrangement for children was expressed among 7 men, all of whom were older than 50 years. These results are discussed in the context of culturally changing concepts of paternal roles in the family and socioeconomic transition in the kibbutz.     

EUTOPIA: THE PROMISE OF BIOTECHNOLOGY AND THE REALIGNMENT OF WESTERN AXIALITY

Abstract. This essay discusses the deep perceptual and social changes that the advanced applications of biotechnology could bring in the West. It examines the probable collapse of a fundamental perceptual bipolarity on which the Western mind and social mobilization have been based since its inception in the West: Athens‐‐Jerusalem. This collapse will quite possibly radically reshape Western perceptions of self and nature and will remodel established constellations and modes of social mobilization and social organization. The radical collapse of the preceding established feature of Western modernity is due to take place in the field of biotechnology, since the latter promises to produce a deliverable perfection of flesh and an equally corporeal personal bliss. I call this promise ``eutopia,'' an actual and tangible utopia‐‐ ``a laboratory on the hill.''     

Relations between 18-month-olds’ gaze pattern and target action performance: A deferred imitation study with eye tracking

Deferred imitation studies are used to assess infants’ declarative memory performance. These studies have found that deferred imitation performance improves with age, which is usually attributed to advancing memory capabilities. Imitation studies, however, are also used to assess infants’ action understanding. In this second research program it has been observed that infants around the age of one year imitate selectively, i.e., they imitate certain kinds of target actions and omit others. In contrast to this, two-year-olds usually imitate the model's exact actions. 18-month-olds imitate more exactly than one-year-olds, but more selectively than two-year-olds, a fact which makes this age group especially interesting, since the processes underlying selective vs. exact imitation are largely debated. The question, for example, if selective attention to certain kinds of target actions accounts for preferential imitation of these actions in young infants is still open. Additionally, relations between memory capabilities and selective imitation processes, as well as their role in shaping 18-month-olds’ neither completely selective, nor completely exact imitation have not been thoroughly investigated yet. The present study, therefore, assessed 18-month-olds’ gaze toward two types of actions (functional vs. arbitrary target actions) and the model's face during target action demonstration, as well as infants’ deferred imitation performance. Although infants’ fixation times to functional target actions were not longer than to arbitrary target actions, they imitated the functional target actions more frequently than the arbitrary ones. This suggests that selective imitation does not rely on selective gaze toward functional target actions during the demonstration phase. In addition, a post hoc analysis of interindividual differences suggested that infants’ attention to the model's social-communicative cues might play an important role in exact imitation, meaning the imitation of both functional and arbitrary target actions.     

Infant directed speech and the development of speech perception: Enhancing development or an unintended consequence?

Infant directed speech (IDS) is a speech register characterized by simpler sentences, a slower rate, and more variable prosody. Recent work has implicated it in more subtle aspects of language development. Kuhl et al. (1997) demonstrated that segmental cues for vowels are affected by IDS in a way that may enhance development: the average locations of the extreme “point” vowels (/a/, /i/ and /u/) are further apart in acoustic space. If infants learn speech categories, in part, from the statistical distributions of such cues, these changes may specifically enhance speech category learning. We revisited this by asking (1) if these findings extend to a new cue (Voice Onset Time, a cue for voicing); (2) whether they extend to the interior vowels which are much harder to learn and/or discriminate; and (3) whether these changes may be an unintended phonetic consequence of factors like speaking rate or prosodic changes associated with IDS. Eighteen caregivers were recorded reading a picture book including minimal pairs for voicing (e.g., beach/peach) and a variety of vowels to either an adult or their infant. Acoustic measurements suggested that VOT was different in IDS, but not in a way that necessarily supports better development, and that these changes are almost entirely due to slower rate of speech of IDS. Measurements of the vowel suggested that in addition to changes in the mean, there was also an increase in variance, and statistical modeling suggests that this may counteract the benefit of any expansion of the vowel space. As a whole this suggests that changes in segmental cues associated with IDS may be an unintended by-product of the slower rate of speech and different prosodic structure, and do not necessarily derive from a motivation to enhance development.     

Profile of urban vs rural drivers detected drink driving via Roadside Breath Testing (RBT) in Queensland,Australia, between 2000 and 2011

ProblemIn Australia, as in many other countries, a disproportionate number of drink driving crashes occur on rural roads.Aims and methodThe study used Queensland Police Random Breath Testing (RBT) data from 2000–2011 to (a) comparing drink driving rates and RBT efficacy in areas of increasing remoteness (b) compare drink driver factors and the circumstances of apprehensions in rural and urban areas.ResultsGenerally, rural areas had a higher detection rate per RBT intercepts and a greater number of apprehensions per licensed drivers than the state average. Main effects showed that rural drivers were more likely to be male and to be a reoffender but less likely to be apprehended between midnight and 5.59 am and after visiting a licensed venue. Urban drivers were more likely to be aged 17–49 years and to be apprehended with a BAC < 0.15%.ConclusionDifferences in RBT effectiveness and drink driving factors and circumstances exist between rural and urban areas.Practical applicationThe greater number of drink drivers in rural areas signal a need for targeted interventions in these areas. To increase the effectiveness of such interventions, further research should examine the mechanisms responsible for these observed differences between rural and urban drink driver.     

Urban–rural differences in children's earliest memories

The purpose of the present study was to address the effects of urban vs. rural upbringing on earliest autobiographical memories. We asked children (aged 10–13) brought up in an urban vs. in a rural setting to report their earliest memories. Earliest memories of children from rural areas were a year later than those of children from urban areas. Moreover, memories of children from rural areas were more likely to contain social interactions and tended to be less detailed compared to those from urban areas. The groups, however, were not different in specificity, autonomous orientation, or emotion. Results are discussed in the context of a social cultural developmental approach.     

高低情感开放性者概率内隐序列学习进程差异

大五人格情感开放性子量表(openness/feeling)能否预测内隐序列学习的问题存在争议。本研究采用概率性内隐序列学习范式, 比较高低情感开放性者在各反应刺激间隔(response stimulus interval, 即RSI)的差异。发现：(1) RSI = 0 ms和250 ms, 高分组在转移组块后习得高概率序列, RSI = 500 ms及以上在其之前习得; 所有RSI点低分组都在其之前习得。每个RSI点只有高分组习得低概率序列。证明随RSI增加两者内隐进程有本质差异, openness/feeling子量表可预测内隐序列学习个体差异。(2)低概率序列可作为测量概率性内隐序列学习及个体差异的新指标, 经典转移组块、再认、生成任务的测量效果却十分有限。
