Recruitment of lateral rostral prefrontal cortex in spontaneous and task-related thoughts

Behavioural and neuroimaging studies suggest that spontaneous and task-related thought processes share common cognitive mechanisms and neural bases. Lateral rostral prefrontal cortex (RPFC) is a brain region that has been implicated both in spontaneous thought and in high-level cognitive control processes, such as goal/subgoal integration and the manipulation of self-generated thoughts. We therefore propose that the recruitment of lateral RPFC may follow a U-shaped function of cognitive demand: relatively high in low-demand situations conducive to the emergence of spontaneous thought, and in high-demand situations depending on processes supported by this brain region. We used functional magnetic resonance imaging to investigate brain activity while healthy participants performed two tasks, each with three levels of cognitive demands, in a block design. The frequency of task-unrelated thoughts, measured by questionnaire, was highest in the low cognitive demand condition. Low and high cognitive demand conditions were each compared to the intermediate level. Lateral RPFC and superior parietal cortex were recruited in both comparisons, with additional activations specific to each contrast. These results suggest that RPFC is involved both when (a) task demands are low, and the mind wanders, and (b) the task requires goal/subgoal integration and manipulation of self-generated thoughts.     

Imprisoned by the past: Unhappy moods lead to a retrospective bias to mind wandering

Evidence suggests that mind wandering is a frequent accompaniment to an unhappy mood. Building on such work, two laboratory experiments used mood induction to assess whether the greater frequency of mind wandering in a low mood is also accompanied by a shift towards a focus on events from the past. Experiment 1 induced moods via video and induction of an unhappy mood was associated with a greater tendency for past-related mind wandering as measured by a post-task questionnaire. In Experiment 2, negative and positive moods were induced in a group of participants using the Velten mood-induction procedure and the temporal focus of mind wandering was measured using experience sampling probes. Analyses indicated that induction of an unhappy mood led to an increase in past-related mind wandering and the magnitude of this change increased with scores on a measure of depressive symptoms. Together these experiments suggest that when the mind wanders in an unhappy mood it is drawn to events from its past.     

信任：父母的代内相似和亲子的代际传递

以往研究指出, 信任有其家庭根源。以116个家庭中的子女及其父母为研究对象考察在家庭中, 父母信任水平是否相似, 父母和子女之间是否存在人际信任的代际传递现象。研究采用投资博弈问卷分别测量了子女和父母的信任水平, 并以送出数量和估计返还数量作为信任的测量指标。结果发现：(1)子女和父母在投资博弈中均表现出一定水平的信任, 且父母的信任表现出相似性; (2)在估计返还数量上, 信任表现出代际传递, 且传递存在性别差异：父亲和母亲的信任水平不能预测女孩的信任水平, 能预测男孩信任水平; 父亲对男孩的影响呈J型曲线, 母亲与男孩的信任水平呈倒U型曲线关系。     

Perspective tracking in progress: Do not disturb

Two experiments tested the hypothesis that indirect false-belief tests allow participants to track a protagonist’s perspective uninterruptedly, whereas direct false-belief tests disrupt the process of perspective tracking in various ways. For this purpose, adults’ performance was compared on indirect and direct false-belief tests by means of continuous eye-tracking. Experiment 1 confirmed that the false-belief question used in direct tests disrupts perspective tracking relative to what is observed in an indirect test. Experiment 2 confirmed that perspective tracking is a continuous process that can be easily disrupted in adults by a subtle visual manipulation in both indirect and direct tests. These results call for a closer analysis of the demands of the false-belief tasks that have been used in developmental research.     

PC-Based Game Features That Influence Instruction and Learner Motivation

PC-based games are currently being used for military training, but the instructional and motivational features of such technology are not well understood. To identify features of training games that influence instruction and motivation, a popular first-person-perspective game with a military theme was analyzed empirically. Twenty-one participants played the “basic training” portion of the game, which included Army background information, virtual marksmanship training, an obstacle course, virtual weapons familiarization, and an urban terrain training mission. The results of this research provide useful information to individuals developing training games, desktop simulations, and interactive multimedia courseware to meet optimal training objectives and strategies.     

Walking in the lost child's tracks: revisiting the therapeutic nature of reclaiming

This paper outlines the research methodology used as part of a professional doctorate in psychoanalytic psychotherapy. The project researched the maternal state of mind following the loss of an infant or small child and the birth of the next baby. Three mothers were seen for psychoanalytic psychotherapy on a weekly basis as part of this research. They were encouraged to bring their new baby to sessions. The author describes how an interest in this area of research developed as a result of working as a child psychotherapist with 'replacement children' (Cain and Cain, 1964). An argument is made to show that the psychoanalytic method is unique and that the psychoanalytic setting may be considered an 'ideal laboratory' (Fonagy and Moran, 1993) for psychoanalytic psychotherapeutic research. Clinical material is used from one case study to show how material can be analysed and demonstrates the research methodology used within the project. The material explores the developing therapeutic relationship and focuses on the way one mother in the research group experienced the loss of a small child prior to the birth of her next baby. Cet article décrit brièvement la méthodologie de recherche employée dans le cadre d'un doctorat professionnel en psychothérapie psychanalytique. Le projet de recherche porte sur l'état psychique maternel à la suite de la perte d'un nourrisson ou d'un enfant en bas âge lorsque un nouveau bébé vient à naître. Dans le cadre de cette recherche, trois mères ont bénéficié d'une psychothérapie psychanalytique à raison d'une séance hebdomadaire. Il leur était proposé d'amener leur bébé aux séances. L'auteur décrit comment son intérêt pour ce champ de recherche s'est développé à partir de son travail de psychothérapeute d'enfants auprès d'"enfants de remplacement" [A. Cain & B. Cain 1964]. Elle affirme que la méthode psychanalytique à sa propre valeur et que le cadre psychanalytique peut être considéré comme un "laboratoire idéal" [P. Fonagy & G. Moran 1993] pour la recherche en psychothérapie psychanalytique. Le matériel clinique d'une étude de cas montre comment l'analyser et illustre la méthodologie de la recherche employée dans ce projet. Ce matériel explore l'évolution de la relation thérapeutique et traite en détail de la façon dont une des mères de l'échantillon a vécu la perte d'un enfant en bas âge avant la naissance de son bébé actuel. Questo articolo mette in rilievo la metodologia di ricerca utilizzata come parte di un dottorato professionale in psicoterapia psicoanalitica. Il progetto di ricerca studiava lo stato mentale materno conseguente la perdita di un neonato o bambino piccolo e la nascita del bambino successivo. Come parte della ricerca tre madri furono seguite una volta alla settimana in psicoterapia psicoanalitica, ed incoraggiate a portare alle sedute i loro nuovi bebe'. L'autore descrive come il suo interesse in questa area si e' sviluppato conseguentemente al suo lavoro come psicoterapeuta infantile con 'bambini sostituti' (Cain e Cain, 1964. Si cerca di mostrare l'unicita' del metodo psicoanalitico e come esso possa essere considerato un 'laboratorio ideale' (Fonagy e Moran, 1993) per la ricerca in psicoterapia psicoanalitica. Viene usato il materiale clinico di un caso per mostrare come esso possa essere analizzato e illustrare il metodo di ricerca usato nel progetto. Il materiale esplora la relazione terapeutica nel suo evolversi e si concentra sul modo in cui una madre nel gruppo di ricerca visse la perdita di un bambino piccolo precedente la nascita dell'altro bebe'. Dieser Artikel umreisst die Forschungsmethodik, die als Teil einer Doktorarbeit in psychoanalytischer Psychotherapie verwendet wurde. Das Projekt erforschte den müterlichen Gemütszustand nach dem Verlust eines Babys oder kleinen Kindes und der Geburt des nächsten Babys. Als Teil dieser Forschung wurden drei Mütter einmal wöchentlich in Psychotherapie gesehen. Sie wurden ermuntert, ihr Neugeborenes zu den Stunden mitzubringen. Die Autorin beschreibt, wie das Interesse in diesem Forschungsbereich sich als Folge ihrer Arbeit als Kinderpsychotherapeutin mit 'Ersatzkindern' entwickelt hatte. (Cain und Cain 1964). Es wird argumentiert, dass die psychoanalytische Methode einzigartig ist und das psychoanalytische Setting als ein 'ideales Labor' (Fonagy und Moran,1993) für psychoanalytische psychotherapeutische Forschung angesehen werden kann. Es wird klinisches Material einer Fallstudie benutzt, um zu zeigen, wie das Material analysiert werden kann und es demonstriert die Forschungsmethodik, die im Projekt benutzt wird. Das Material erforscht die sich entwickelnde therapeutische Beziehung und legt den Schwerpunkt auf die Art und Weise, wie eine Mutter in der Forschungsgruppe den Verlust eines kleinen Kindes vor der Geburt ihres nächsten Babys erlebte.     

Do the right thing: The assumption of optimality in lay decision theory and causal judgment

Human decision-making is often characterized as irrational and suboptimal. Here we ask whether people nonetheless assume optimal choices from other decision-makers: Are people intuitive classical economists? In seven experiments, we show that an agent’s perceived optimality in choice affects attributions of responsibility and causation for the outcomes of their actions. We use this paradigm to examine several issues in lay decision theory, including how responsibility judgments depend on the efficacy of the agent’s actual and counterfactual choices (Experiments 1–3), individual differences in responsibility assignment strategies (Experiment 4), and how people conceptualize decisions involving trade-offs among multiple goals (Experiments 5–6). We also find similar results using everyday decision problems (Experiment 7). Taken together, these experiments show that attributions of responsibility depend not only on what decision-makers do, but also on the quality of the options they choose not to take.     

Private Investigations of White‐Collar Crime Suspicions: A Qualitative Study of the Blame Game Hypothesis

The activity of private investigations by fraud examiners is a business of lawyers, auditors, and other professionals who investigate suspicions of financial crime by white‐collar criminals. This paper presents results from an empirical study of investigation reports. The available sample consists of 28 reports written mostly by auditing firms such as Deloitte, Ernst & Young, and PwC. The blame game can occur at two stages in a private investigation. First, the mandate formulated by a client may point investigators in a specific direction. Next, investigators sometimes suffer from a tunnel view of predetermined opinions. In the sample of 28 investigations reports, more than half of them involve potential blame game victims.
