ATTACKS ON LINKING OR A DRIVE TO COMMUNICATE? TOLERATING THE PARADOX

The notion of attacks on linking, as described by Bion, may depict a patient's drive to communicate the internalization of a destructive relationship between a primary object and an infant. This may be enacted between patient and analyst in the here and now of the analysis, whereby fragmentation and numbing of thinking may point to a primitive catastrophe relived in the psychoanalytic setting. The patient's material may seem incoherent, but incoherence might be the communication the patient is unconsciously trying to convey. Thus, the notion of attacks on linking depicts a paradoxical, caesural experience in which the attack on linking is itself a link.     

The Swedish Hayling task,and its relation to working memory,verbal ability,and speech‐recognition‐in‐noise

Cognitive functions and speech‐recognition‐in‐noise were evaluated with a cognitive test battery, assessing response inhibition using the Hayling task, working memory capacity (WMC) and verbal information processing, and an auditory test of speech recognition. The cognitive tests were performed in silence whereas the speech recognition task was presented in noise. Thirty young normally‐hearing individuals participated in the study. The aim of the study was to investigate one executive function, response inhibition, and whether it is related to individual working memory capacity (WMC), and how speech‐recognition‐in‐noise relates to WMC and inhibitory control. The results showed a significant difference between initiation and response inhibition, suggesting that the Hayling task taps cognitive activity responsible for executive control. Our findings also suggest that high verbal ability was associated with better performance in the Hayling task. We also present findings suggesting that individuals who perform well on tasks involving response inhibition, and WMC, also perform well on a speech‐in‐noise task. Our findings indicate that capacity to resist semantic interference can be used to predict performance on speech‐in‐noise tasks.     

2～3.5岁儿童执行功能发展特点及其言语能力的影响

2~3.5岁是婴儿成长到幼儿的重要发展转折期,也是儿童执行功能及言语能力的发展萌芽期。研究通过测查北京市81名2~3.5岁儿童在固定盒子任务、搭积木任务、A非B任务和皮博迪图片词汇测验上的表现,探究了该年龄段儿童执行功能的发展特点、各成分间的内部关系、以及言语能力对执行功能的影响。结果发现:(1)在2~3.5岁期间,除认知灵活性外,儿童的工作记忆与抑制控制均快速发展,其中,2.5岁前后是工作记忆与抑制控制的重要发展时期;(2)在2~3岁期间,认知灵活性与工作记忆之间相关密切,在3~3.5岁期间,认知灵活性与抑制控制的相关密切,3岁是儿童执行功能内部成分关系的重要发展转折期;(3)在2~3.5岁期间,儿童言语能力呈现快速发展,并且言语能力对该年龄段执行功能各成分间关系产生一定的影响,但不同言语能力的儿童在执行功能各成分的表现并没有显著差异。     

‘Put Your Money Where Your Mouth Is!’: Effects of Streaks on Confidence and Betting in a Binary Choice Task

Human choice under uncertainty is influenced by erroneous beliefs about randomness. In simple binary choice tasks, such as red/black predictions in roulette, long outcome runs (e.g. red, red, red) typically increase the tendency to predict the other outcome (i.e. black), an effect labeled the “gambler's fallacy.” In these settings, participants may also attend to streaks in their predictive performance. Winning and losing streaks are thought to affect decision confidence, although prior work indicates conflicting directions. Over three laboratory experiments involving red/black predictions in a sequential roulette task, we sought to identify the effects of outcome runs and winning/losing streaks upon color predictions, decision confidence and betting behavior. Experiments 1 (n = 40) and 3 (n = 40) obtained trial‐by‐trial confidence ratings, with a win/no win payoff and a no loss/loss payoff, respectively. Experiment 2 (n = 39) obtained a trial‐by‐trial bet amount on an equivalent scale. In each experiment, the gambler's fallacy was observed on choice behavior after color runs and, in experiment 2, on betting behavior after color runs. Feedback streaks exerted no reliable influence on confidence ratings, in either payoff condition. Betting behavior, on the other hand, increased as a function of losing streaks. The increase in betting on losing streaks is interpreted as a manifestation of loss chasing; these data help clarify the psychological mechanisms underlying loss chasing and caution against the use of betting measures (“post‐decision wagering”) as a straightforward index of decision confidence. © 2014 The Authors.

Knowledge of memory functions in European and Asian American adults and children: The relation to autobiographical memory

This study investigated explicit knowledge of autobiographical memory functions using a newly developed questionnaire. European and Asian American adults (N = 57) and school-aged children (N = 68) indicated their agreement with 13 statements about why people think about and share memories pertaining to four broad functions—self, social, directive and emotion regulation. Children were interviewed for personal memories concurrently with the memory function knowledge assessment and again 3 months later. It was found that adults agreed to the self, social and directive purposes of memory to a greater extent than did children, whereas European American children agreed to the emotion regulation purposes of memory to a greater extent than did European American adults. Furthermore, European American children endorsed more self and emotion regulation functions than did Asian American children, whereas Asian American adults endorsed more directive functions than did European American adults. Children's endorsement of memory functions, particularly social functions, was associated with more detailed and personally meaningful memories. These findings are informative for the understanding of developmental and cultural influences on memory function knowledge and of the relation of such knowledge to autobiographical memory development.     

禀赋效应的心理机制及其影响因素

禀赋效应是指个体在拥有某物品时对该物品的估价高于没有拥有该物品时的估价的现象。这一现象在行为经济学中普遍存在。禀赋效应的研究范式包括经典研究范式与物物交换范式。禀赋效应的心理机制主要包括损失规避与查询理论。禀赋效应的影响因素主要包括认知角度、动机、情绪、交易物品的特征、研究设计的选择等。未来的研究需要从禀赋效应的适用条件、产生根源、研究范式的改进等方面进一步探讨。     

Why Me? Why Not Me?

The decision to undergo BRCA testing is very complex and emotionally laden. This decision can be further complicated by the loss of a mother at an early age. The following personal account by a genetic counselor discusses the testing process and the struggle to accept the results and reframe one’s self-identity. The sensitive nature of this testing and the implications for other family members is explored.     

A Bizarre Property Equivalent to the -Fan Theorem

It is shown, with intuitionistic logic, that if every locallyconstant function from to has a property akinto constancy, then the fan theorem for -bars holds, and conversely.
