Collaborative mother–toddler communication and theory of mind development at age 4

Focusing on social pragmatics, this longitudinal study investigated the contribution of mother–toddler collaborative communication to theory of mind (ToM) development at age 4. At age 2½, 78 toddlers (42 boys) and their mothers were observed during pretend play. At age 4, children were tested using 4 false belief understanding tasks. Both mothers and toddlers engaged in more collaborative (inform, guide/request, and support/confirm) than non-collaborative communication acts. Other-focused collaborative acts of support/confirm by mothers and toddlers predicted children's false belief understanding, even after controlling for 5 covariates. In addition, as active agents in their own ToM development, the contribution of toddlers' collaborative acts to false belief understanding was independent of their mother's. Finally, the way toddlers and their mothers co-constructed their communication mattered. Only when toddlers engaged in high levels of collaborative acts, the mothers' high levels of collaborative acts demonstrated a positive effect on children's ToM development. The applied implications of these findings are discussed.     

医学影像学见习应用PACS教学法与传统读片教学法的对比研究

将中南大学湘雅医学院2010级临床医学五年制197名学生随机分成两组,在医学影像学见习教学过程中分别应用影像存储及传输系统（PACS）教学法（98人）及传统读片教学法（99人）,学期结束时对两组学生考试成绩进行分析,并对PACS组学生进行问卷调查及结果分析.统计数据显示,PACS组学生读片测验及卷面考试中,病例分析题成绩显著高于传统读片组,问卷调查显示PACS组学生大多数认可该教学方法.因此,应用PACS教学有助于提高学生的临床分析能力及主动学习的能力,是学生欢迎的教学方式.但对医学影像学基本知识的传授,应用PACS法较传统读片法并无明显优势.     

Constructive criticism: An evaluation of Buller and Hardcastle's genetic and neuroscientific arguments against Evolutionary Psychology

David Buller and Valerie Hardcastle have argued that various discoveries about the genetics and nature of brain development show that most “central” psychological mechanisms cannot be adaptations because the nature of the contribution from the environment on which they are based shows they are not heritable. Some philosophers and scientists have argued that a strong role for the environment is compatible with high heritability as long as the environment is highly stable down lineages. In this paper I support this view by arguing that the discoveries Buller and Hardcastle refer to either do not show as strong a role for the environment as they suggest, or these discoveries show that the brain's developmental process depends in many cases on input from the environment that is highly stable across generations.     

Attachment and Mother-Child Communication in Adjustment to the Death of a Father Among Cambodian Adolescents

This study examined quality of attachment to the mother and child-mother communication in adolescents' adjustment to the death of a father. Forty-eight Cambodian adolescents whose father had died within the previous 3 years completed a set of measures that included attachment, communication, grief, and self-esteem. Results showed that quality of attachment to the mother and whether the adolescent communicated with the mother about the father and found this to be helpful were positively related to adaptive grief and self-esteem. Moreover, support was shown for an indirect effect of quality of attachment to the mother on adaptive grief as mediated by communication. Implications of the findings for quality of attachment in adjustment to bereavement in a non-Western cultural context are discussed.     

Non-verbal expressivity in alexithymia: A study on emoji use in text messaging across varying levels of alexithymia

The present study examined whether emoji use would be quantitatively and/or qualitatively altered in alexithymia. 646 individuals (Mean Age = 23.11, SD = 7.03; 424 Female) with varying levels of alexithymia took part in a series of vignettes where they were positioned as senders of hypothetical text messages. Participants were tasked to opt in or out of tagging an emoji onto positive and negative text messages. Emoji use frequency was diminished at the high end of the alexithymic continuum, relative to the middle and low spectrums. However, emoji for positive and negative text messages were used with similar patterns of frequency across alexithymic groups of varying severity, suggesting that emoji use is quantitatively but not qualitatively altered in alexithymia.     

How did I get here? Individual differences in perceived retrospective personality change

People's beliefs about their own past personality development are associated with current and future self-concepts. Here, we report on 2 studies designed to elucidate the way people think about retrospective changes to their own personality. We found that incremental theories of personality were associated with greater perceived retrospective personality change and that perceived retrospective personality change was associated with the belief that specific volitional and situational causes were involved. In addition, we found that across all Big-5 personality traits and agency, higher current standing (in the socially desirable direction) was positively associated with greater perceived retrospective personality change. This research demonstrates how people vary in their beliefs about retrospective personality change.     

Going virtual in the early years: 30-month-old toddlers recognize commonly used emojis

People nowadays do not only display facial expressions in face to face communication but also in on-line communication using graphical symbols named emojis. The present study explored 30-month-old toddlers’ ability to recognize emojis that represented six basic human emotions. In the study, 38 toddlers first saw scenarios that elicited different emotions in an actor and were asked to visually identify the matching emoji in the presence of a distractor. Eye-tracking results showed that toddlers could correctly identify the emoji that represented the emotion in each scenario. Toddlers then heard different emotion words and were again found to be able to identify the matching emoji. These findings provide preliminary evidence that the ability to recognize and understand the emotional value of emotion symbols in the virtual world emerges early in development.     

Factors influencing career maturity in the South African National Defence Force: A diagnostic approach

This study investigated factors influencing the career maturity of young members of the South African National Defence Force (SANDF). A sample of 310 young SANDF members (females=35%, blacks=90%) completed the following measures: career maturity inventory-revised, the career decision self-efficacy scale, the military hardiness scale, and the seven habits profile. They also completed a biographical information form. Data were analysed using multiple regression to predict career maturity from career decision self-efficacy, self-appraisal, occupational information, goal selection, planning, problem solving, hardiness, control, challenge, commitment, conscientiousness, life balance, pro-active behaviour, life goals, self-management, mutual-benefit thinking, listening, teamwork, continuous improvement and life skills. Findings suggest self-efficacy, occupational information, self-appraisal, commitment, challenge, emotional intelligence and continuous improvement have the strongest influence on career maturity. The results indicated that self-efficacy, life skills and personal drive empower young members to seek employment.     

‘You have to treat the person,not the mouth only’: UK dentists’ perceptions of communication in patient consultations

Effective communication between patients and health professionals is a key component of patient-centred care. Although there is a large body of literature focusing on doctor-patient communication, there has been limited research related to dentist-patient communication, especially presented from the dentists’ perspective. The aim of our study was to explore UK dentists’ perceptions of communication in their consultations, and the factors they perceive may influence this. We conducted semi-structured interviews with eight dentists in UK dental NHS practices. Thematic analysis revealed three themes (‘Treating the whole person’, ‘Barriers to patient-centred communication’ and ‘Mutuality of communication’), which reflected the dentists’ perceptions of their own communication during consultations, the patients’ interaction skills, attitudes (and characteristics that may affect them), and external factors, such as time constraints, that can influence dentist-patients’ encounters. These in-depth accounts are valuable, in that we see what dentists perceive is important, obstructive and facilitative. They report using a patient-centred approach in their everyday dental practice; however this is often difficult due to factors such as time constraints. Although they emphasized that the patient has an active role to play in the communication process, it may be the case that they also need to play their part in facilitating this.
