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.     

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。     

Pushing mom away: Embodied cognition and avoidant attachment

The objective of this research was to examine embodied psychological defense—the way in which defensive processes are manifest in basic motor responses. Forty-one participants were instructed to physically push or pull a lever in response to lexical stimuli presented on a computer display. Participants who were relatively avoidant with respect to attachment were faster to push the lever away from themselves when presented with the word “mom.” These results suggest that basic avoidant motives are automatically primed when attachment-related stimuli are processed, and that these tendencies manifest themselves in basic, motor-specific ways.     

个人-组织匹配的概念、测量策略及应用:基于互动性与灵活性的反思

个人-组织匹配(Person-Organization Fit,简称P-O匹配)的提出契合了组织行为学中人与情境双向互动的研究趋势,同时也符合组织及其成员灵活应对动态格局的现实要求。这种以双边互动性和匹配灵活性为出发点和立足点的研究是P-O匹配的特色所在。然而,目前该领域考察呈现出淡化原有独特立意的倾向。为此,我们在梳理P-O匹配学术背景和社会背景的基础上,强调将互动性和灵活性这两点基本要求融入其概念界定、测量策略的选取及应用课题当中,是为P-O匹配特色的重拾。

Psychological threat and extrinsic goal striving

Although people generally endorse intrinsic goals for growth, intimacy, and community more than extrinsic goals for money, appearance, and popularity, people sometimes over-emphasize extrinsic goals, to the potential detriment of their well-being. When and why does this occur? Results from three experimental studies show that psychological threat increases the priority that people give to extrinsic compared to intrinsic goals. This was found in the case of existential threat (Study 1), economic threat (Studies 2), and interpersonal threat (Study 3). Discussion focuses on the possible reasons why threat breeds extrinsic orientations.
