Understanding anhedonia in schizophrenia through lexical analysis of natural speech

Anhedonia is a negative prognostic indicator in schizophrenia. However, the underlying nature of this emotional deficit is unclear. Laboratory studies examining patients’ emotional reactions under controlled circumstances have failed to find evidence for a diminished hedonic response, instead finding that patients’ reactions to laboratory stimuli are characterised by high levels of negative emotion. The present study employed lexical analysis of natural speech in 52 patients and 49 non-patient controls while they discussed separate neutral, pleasant and unpleasant autobiographical memories. Patients with clinically rated anhedonia, versus other patients and controls, showed a dramatic increase in negative emotion expression when discussing pleasurable memories, but they showed no corresponding decrease in positive emotion. These findings provide further evidence that “anhedonia” is more reflective of negative emotional states than the absence of positive ones. These findings also raise questions about how positive and negative emotions can be simultaneously co-activated in patients with schizophrenia.     

Some Oedipal problems in work with adopted children and their parents

This paper has two main theses. Firstly that Oedipal material is a particular feature of clinical work with adopted children; secondly, that the concept of developmental deficit, and not only that of psychic defence, is essential to an understanding of this aspect of the work with adopted children and their families. Three levels are distinguished at which Oedipal difficulties are manifest: the first two within the individual child and the third within the triangle formed by the child, his adoptive parents and the child psychotherapist. Some consideration is given to the limitations of a conventional treatment framework for containing the powerful Oedipal dynamic forces at play when an adopted child is a patient in individual psychotherapy. Dieser Artikel hat zwei Hauptthesen. Erstens, dass ödipales Material ein besonderes Merkmal der klinischen Arbeit mit adoptierten Kindern ist; zweitens dass das Konzept eines Entwicklungsdefizit, und nicht nur das eines psychischen Abwehrmechanismus, für das Verstehen dieses Aspekts der Arbeit mit adoptierten Kindern und ihren Familien unerlässlich ist. Es werden drei Stufen differenziert, in denen sich ödipale Schwierigkeiten manifestieren: die ersten zwei innerhalb des Kindes und die dritte innerhalb des Dreiecks, das vom Kind, seinen Adoptiveltern und dem Kindertherapeuten gebildet wird. Es werden überlegungen bezüglich der Grenzen des konventionellen Behandlungsrahmens angestellt, inwieweit er die mächtigen ödipalen dynamischen Kräfte, die im Spiel sind, 'containen' kann, wenn ein adoptiertes Kind Patient in individueller Psychotherapie ist. Dans son texte, l'auteur développe deux thèses principales: d'abord, que le matériel ?dipien est d'une importance particulière dans le traitement d'enfants adoptés; et, ensuite, que le concept de trouble déficitaire du développement, en plus de celui de défense psychique, est essentiel pour comprendre cet aspect de la prise en charge d'enfants adoptés et de leur famille. L'auteur distingue trois niveaux auxquels se manifestent la problématique ?dipienne?:?les deux premiers concernent l'enfant lui-même en tant qu'individu, le troisième renvoie au triangle composé de l'enfant, de ses parents adoptifs et du psychothérapeute. Certaines limitations imposées par le cadre thérapeutique traditionnel sont ensuite explorées, notamment par rapport à la possibilité de contenir la puissante dynamique ?dipienne évoquée dès qu'un enfant adopté est pris en psychothérapie individuelle. Questo articolo sostiene due tesi principali. La prima e' che il materiale edipico e' una caratteristica particolare del lavoro clinico con bambini adottati; la seconda e' che il concetto di deficit evolutivo, e non solo quello di difesa psichica, e' essenziale per capire questo aspetto del lavoro con bambini adottati e le loro famiglie. Vengono distinti tre livelli in cui si manifestano le difficolta' edipiche: i primi due all'interno del singolo bambino, il terzo all'interno del triangolo formato dal bambino, dai suoi genitori adottivi e dallo psicoterapeuta infantile. Vengono fatte alcune considerazioni sulle limitazioni che il contesto terapeutico convenzionale ha nel contenere le potenti forze dinamiche edipiche in gioco quando un bambino adottato diventa paziente in terapia individuale.     

Can Attention Deficit Hyperactivity Disorder and Fetal Alcohol Spectrum Disorder be differentiated by motor and balance deficits?

There is an ongoing debate regarding the diagnostic overlap between Attention Deficit Hyperactivity Disorder (ADHD) and Fetal Alcohol Spectrum Disorder (FASD). Differential diagnosis is important because of treatment implications. Children aged 7–10 years (47 ADHD, 30 FASD, 39 controls) participated. The Movement Assessment Battery for Children (M-ABC) and the Clinical Observations of Motor and Postural Skills (COMPS) were used. Force plate and electromyography data were collected during static balance and balance perturbation. On the M-ABC both children with ADHD and FASD had more motor problems than controls. The ADHD-Combined and the ADHD-Predominantly Inattentive subgroups were similarly affected in their fine motor skills. On the COMPS, the majority of children in both groups performed in the normal range, but for those children clinically affected, it was the children with ADHD who were more likely to be severely impaired. The children with ADHD were characterized by early onset latencies of the tibialis anterior muscles and increased amplitudes of the gastrocnemius muscles. Difficulty scaling muscle force reflecting medial cerebellar involvement may be the key problem in ADHD. Cerebellar involvement in the postural instability in FASD awaits further study.     

The Importance of Parental Attributions in Families of Children with Attention-Deficit/Hyperactivity and Disruptive Behavior Disorders

Presents a social-cognitive model outlining the role of parental attributions for child behavior in parent–child interactions. Examples of studies providing evidence for the basic model are presented, with particular reference to applications of the model in families of children with Attention-Deficit/Hyperactivity Disorder (ADHD) and/or oppositional defiant/conduct disordered behavior. Parent or child factors that may moderate the operation of links within the model are suggested, and evidence of such moderator effects is presented. The conceptualization and measurement of parental attributions also are discussed. The limitations of the model and existing evidence, as well as recommendations for future research in this area are presented throughout the paper. The paper concludes with a summary of the clinical implications of the model and research on parental attributions with regards to improving interventions for families of children with attentional and disruptive behavior problems.     

Appraisal of Memory Functioning and Memory Performance in Healthy Ageing and Early-Stage Alzheimer's Disease

ABSTRACT

Background/Aims: To compare memory evaluations in healthy older people and people with Alzheimer's disease (AD) and present standardised individual and dyadic methods for classifying degree of memory awareness in the participants with dementia. Methods: Cross-sectional study evaluating awareness of memory functioning and performance and providing normative data for healthy individuals and couples, together with comparison data from people with AD. Results: As a group, older people are reasonably accurate raters of their own memory functioning and performance, although considerable individual differences can be observed, and control dyads show good comparative accuracy. Comparing normative data from the control group to data from participants with AD confirms that significant overestimation is a frequent feature among people with dementia, with approximately two-thirds showing this pattern, although significant under-estimation is also reliably observed in a small proportion of people with dementia. Different types of measure elicit different profiles of memory awareness in participants with dementia. Conclusion: Normative data from older individuals and couples provides useful percentile-based indices for determining level of memory awareness in people with dementia.     

Educators' Perceptions of Attention Deficit Hyperactivity Disorder: An Exploratory Study

The study investigated the perceptions of educators about Attention Deficit Hyperactivity Disorder, specifically their views on its incidence, causes and appropriate interventions in school settings. Five purposively selected educators from a private school participated in the study. Ethnographic interview was used to collect and analyze the data. The results revealed that the educators considered ADHD mainly a physiological disorder with primarily genetic and environmental causes. Regardless the educators preferred medication as the intervention method despite being aware of additional intervention methods.     

Overcoming a child's resistance to late adoption: how one new attachment can facilitate another

The paper describes the difficulty which late-adopted children may have in forming attachments to their new parents. It considers the nature of the disorganized attachment pattern which many of these deprived, abused children display and the origin of this pattern in experiences of 'fright without solution'. The psychotherapy of a 9-year-old, late-adopted boy is used to illustrate long-standing resistance to new attachments on account of defences on which security depends, and the persistence of loyalty to prior internal attachment representations. Change becomes possible through psychotherapy in which earlier negative attachment models are externalized together with their associated feelings of 'fright without solution'. For this boy, a long period of rejection of the therapist gave way to a new capacity to play together; this was associated with the development of positive attachments to the boy's adoptive parents.

为什么会出现“舌尖现象”?——TOT现象发生机制之争

舌尖现象(tip-of-the-tongue,TOT)是一种普遍发生的现象,但是发生TOT的对象、情景、机制等却是特殊和复杂的。因此,它引起了研究者的关注,尤其是在其产生机制上更是存在着很多争论。国外研究者提出了部分激活理论、传递缺陷理论、障碍物假说、神经网络模型、元认知理论等。但研究者大多都基于单一条件或情景来探讨TOT的产生,因此提出的理论的使用范围,解释广度等均有局限。关于TOT依然有许多疑惑,同时也存在值得探讨的课题。
