Trajectory of risky decision making for potential gains and losses from ages 5 to 85

The ability to make advantageous decisions in the face of uncertainty is an essential human skill, yet the development of such abilities over the lifespan is still not well understood. In the current study, from childhood through older adulthood, we tracked the developmental trajectory of risk taking for gains and losses, and expected value (EV) sensitivity in risky choices. In the gain domain, risk‐taking decreased consistently across the lifespan. In the loss domain, risk‐taking was relatively constant across ages, a result we attribute to the pervasiveness of loss aversion. EV sensitivity showed an inverted‐U‐shaped function, increasing from childhood to adulthood but then decreasing for the elderly, which occurred for both risky gains and risky losses. This finding is consistent with neuropsychological and neuroanatomical evidence concerning the role of the frontal lobe in decision making, which is relatively late to develop during childhood but may degrade earlier in the later years.

Meaning and object in Freud's theory of language

This article sets out to challenge the interpretation of Freud's views on the origins of the meaning of language according to which meaning always originates from an act of naming. In Freud's terms, word‐presentations would originally denote object‐ or thing‐presentations and gain meaning through this reference. This interpretation claims that this view was already expressed in Freud's On Aphasia (1891) and influenced all his later theory of language. To oppose this claim, three conceptions proposed by Freud are discussed that strongly suggest the participation of language in the construction of the field of objects: a metapsychological hypothesis (the concepts of word‐, thing‐, and object‐presentation), the explanation of a psychopathological phenomenon (the genesis of a fetishistic object‐choice), and a concept concerning the foundations of the psychoanalytic method of dream interpretation (secondary elaboration). As a conclusion, it is argued that Freud's early views in On Aphasia (1891) can be alternatively understood such as to allow for a different view of language and its relationship with objects.     

Theory of Mind and Executive Functions in Young Bilingual Children

Few studies have explored the relationship between theory of mind (ToM), executive function (EF), and bilingualism at the same time. In this study 14 young bilingual children were compared with monolingual children on a test battery composed of 5 ToM tests, 5 EF tests, and 1 test of general language ability. The result showed that despite significantly lower verbal ability, the bilingual children outperformed the monolingual ones on tests of EF. There were no differences in ToM performance. The authors argue that there is a strong relationship between bilingualism and EF, but, contrary to results from earlier studies, they could not find any relationship between bilingualism and ToM. EF did not predict ToM performance. Lack of a significant relationship could be due to the children's young age and consequently their low scores on the ToM tasks.     

Is positive thinking in anticipation of a performance situation better than distraction? An experimental study in preadolescents

The current study compares the effects of experimentally induced positive anticipatory thinking and distraction in preadolescents aged 12–13. Eighty‐seven participants were instructed to either engage in positive anticipatory thoughts or perform a distraction task while preparing to perform a sporting activity in front of their peers. Results revealed that trait social anxiety was associated with more negative estimates of sport performance and catastrophic thoughts relating to the impending sport activity. Additionally, compared to children who distracted, children in the positive anticipation condition showed significantly increased anxiety levels, more catastrophic thoughts and more negative predictions of sport performance and appearance, although these effects did not appear to interact with trait social anxiety. Finally, no significant manipulation effect on participants’ observable behavior was found. The findings further highlight the utility of distracting from an impending, anxiety‐provoking situation to keep anxious feelings to a low level.     

Child psychotherapy with looked after and adopted children: a UK national survey of the profession

Relatively little empirical data is available about the range of work undertaken by child psychotherapists in the UK; however, previous surveys have shown high levels of complexity amongst children referred to child psychotherapists and an increasing proportion of work with children in foster or adoptive placements. Aims: We sought to examine child psychotherapists’ working practices with looked after and adopted children (LAAC), including the types of activities undertaken and their views on this work. Method: An online survey was designed to elicit this information from the members of the Association of Child Psychotherapists (ACP), the regulatory body for child psychotherapists in the UK. The survey included a number of categorical and open-ended questions, which were analysed quantitatively and qualitatively. Findings: 215 responses were received (24.5% of the eligible ACP membership). The vast majority of the sample were working with LAAC in some context (87.9%). Respondents were conducting a range of work: the most frequently conducted activities were assessment (83.7%), direct psychotherapy (82.3%), work with foster carers and adoptive parents (80.9%) and consultation with the professional network (76.7%). Thematic analysis of qualitative data suggested the complexity of problems amongst the children attending psychotherapy, as well as the perceived need for long-term work with these children. Many respondents placed emphasis on the importance of working with the professional network around the child, including foster carers and adoptive parents, despite feeling that this was often an under-resourced area of child and adolescent mental health services. The implications of the survey for practice and future research are discussed.     

Implicit learning and emotional responses in nine-month-old infants

To study the interplay between motor learning and emotional responses of young infants, we developed a contingent learning paradigm that included two related, difficult, operant tasks. We also coded facial expression to characterise emotional response to learning. In a sample of nine-month-old healthy Chinese infants, 44.7% achieved learning threshold during this challenging arm-conditioning test. Some evidence of learning was observed at the beginning of the second task. The lowest period of negative emotions coincided with the period of maximum movement responses after the initiation of the second task, and movement responses negatively correlated with the frequency of negative emotions. Positive emotions, while generally low throughout the task, increased during peak performance especially for learners. Peak frequency of movement responses was positively correlated with the frequency of positive emotions. Despite the weak evidence of learning this difficult task, our results from the learners would suggest that increasing positive emotions, and perhaps down-regulating negative emotional responses, may be important for improving performance and learning a complex operant task in infancy. Further studies are necessary to determine the role of emotions in learning difficult tasks in infancy.     

Generalisation of the Clark and Wells cognitive model of social anxiety to children's athletic and sporting situations

Research has shown that social anxiety generalises to sporting and athletic situations. The present study explored the applicability of the Clark and Wells model of social anxiety – and its metacognitive extension – to sport anxiety. Participants were 290 students aged 11–13 years, who completed measures of sport anxiety, social anxiety, depression and cognitive variables implicated by the model. Hierarchical regression analysis indicated that performance attitudes, performance cognitions, anticipatory and post-event processing were predictive of sport anxiety, after controlling for social anxiety and depression. In addition, the association between performance attitudes and sport anxiety was stronger at higher levels of anticipatory and post-event processing. These results suggest that the Clark and Wells cognitive model – and its metacognitive extension – is applicable to children with sport anxiety.     

影响动作图片命名的因素

图片是研究词汇习得与加工的重要材料, 而名词和动词是最主要的两类实词。然而, 目前较少有研究考察汉语中的动词加工过程, 也没有标准化的动词图片库。本研究通过成人图片命名和评定任务, 获得了265张动词图片的中文名称、命名反应时, 以及H值、命名一致性、熟悉性、视觉复杂性、表象一致性和口语习得年龄等指标, 同时也探索了影响动作图片命名反应时的因素。逐步回归分析结果发现, H值、熟悉性和视觉复杂性这三个变量可解释动词图片命名反应时72.4%的变异。此外, 本研究根据图片命名反应时将动词图片加工难度分成了五个等级。研究发现, 与名词图片相比, 动词图片的视觉复杂性更高、命名一致性更低、命名反应时更长。本研究获得的各项心理语言学指标有望为后续关于动词加工的实验研究提供重要的参考资料。
