Demographically Adjusted Normative Standards for New Indices of Performance on the Paced Auditory Serial Addition Task (PASAT)

Logical grammatical structures comprehension is the ability to understand the relations between objects, actions, and qualities in spoken and written sentences. The Logical Grammatical Structures Test (LGST) was especially devised to assess these abilities in children and adolescents. In the present study the LGST was administered to 405 healthy Dutch children and adolescents. The aims of the present study were (i) to evaluate the psychometric properties of the LGST (using an Item Response Theory framework), and (ii) to establish demographically corrected normative data. The results showed that there was a strong curvilinear relationship between age and LGST performance, i.e., the relative improvement in ability level was much more pronounced for younger children (aged below 14 years) than for older children (aged above 14 years). Level of parental education was positively associated with the LGST performance. Normative data that took the relevant demographic variables into account were established, and it was shown that the LGST had sound psychometric properties.     

Episodic memory and self-awareness in Asperger Syndrome: Analysis of memory narratives

Previous findings from researchers on individuals with Asperger Syndrome (AS) suggest peculiarities of autobiographical memory (AM). They have shown a personal episodic memory deficit in the absence of a personal semantic memory impairment. The primary aim of this study was to explore AM in individuals with AS, and more specifically to investigate the link between episodic memory, self-awareness, and autonoetic consciousness through language analysis. We asked fifteen adults with AS and fifteen age- and IQ-matched controls to recall autobiographical memories from three life periods. Recorded interviews were processed using Alceste software. We found that participants with AS recalled fewer and less-detailed episodic memories than did controls. A content analysis revealed that family-related vocabulary as well as possessive pronouns was significantly less frequent in AS interviews than in those of controls. In conclusion, our results support the hypothesis that a deficiency of episodic memory may be due to poor awareness of the self in social relationships. Reduced use of possessive pronouns may also indicate less self-investment in life experiences, which would in turn impact recall.     

Use of alcohol intoxication codes for serious non-fatal hospitalised injury

Aim

To determine the extent to which ICD-10 alcohol intoxication codes are used for serious hospitalised injury and the distribution of these codes according to gender, age, injury mechanism and intent, severity of injury, and whether the patient was treated in an Intensive Care Unit.

Design

Cross-sectional study.

Setting

New Zealand.

Participants

All injury hospital discharges in 2010 that met specified severity criteria.

Measurements

Cases which had a measurement of BAC (Y90) coded, or only a subjective assessment of alcohol intoxication (F10.0).

Findings

2.5% had a blood alcohol recorded (Y90) and a further 3% were coded as being intoxicated but there was no blood alcohol code. All factors investigated were shown to be independently associated with the assignation of codes. Notable findings were the elevated odds of an alcohol code for males, assault and the more severe injuries.

Conclusions

Assessment of alcohol intoxication among seriously injured persons appears to be very uncommon. The development of a standardised instrument for clinical judgement of intoxication would be highly desirable.     

Social cognition and interaction training for patients with stable schizophrenia in Chinese community settings

Accumulated evidence suggests that Social Cognition and Interaction Training (SCIT) is associated with improved performance in social cognition and social skills in patients diagnosed with psychotic disorders. The current study examined the clinical utility of SCIT in patients with schizophrenia in Chinese community settings. Adults with stable schizophrenia were recruited from local community health institutions, and were randomly assigned to SCIT group (n=22) or a waiting-list control group (n=17). The SCIT group received the SCIT intervention plus treatment-as-usual, whereas the waiting-list group received only treatment-as-usual during the period of the study. All patients were administered the Chinese versions of the Personal and Social Performance Scale (PSP), Face Emotion Identification Task (FEIT), Eyes task, and Attributional Style Questionnaire (ASQ) at baseline of the SCIT treatment period and at follow-up, 6 months after completion of the 20-week treatment period. Patients in SCIT group showed a significant improvement in the domains of emotion perception, theory of mind, attributional style, and social functioning compared to those in waiting-list group. Findings indicate that SCIT is a feasible and promising method for improving social cognition and social functioning among Chinese outpatients with stable schizophrenia.     

Theory of mind deficits in patients with mild symptoms of major depressive disorder

The aim of this study was to investigate theory of mind (ToM) in a sample of depressed patients with mild symptom severity using a measure with varied cognitive processing demands. Patients demonstrated impaired performance on second-order, cognitively demanding ToM scenarios. Reduced ToM ability was associated with poor psychosocial functioning.     

Re-examining the cognitive phenotype in autism: A study with young Chinese children

Deficits consistently found in autism include an impaired “theory of mind”, weak central coherence, and deficits in executive function. The current study examined whether this traditional cluster of symptoms existed in a group of Chinese-speaking children with autism. Sixteen high-functioning, non-retarded children with autism were matched to 16 typically developing (TD) children on gender, non-verbal IQ and age. Non-verbal IQ's of all participants were measured using the Raven Progressive Matrices. Each participant was tested individually on measures of “theory of mind”, central coherence and executive function. Results indicated that most, but not all, participants with autism performed significantly poorer on two standard measures of first-order “theory of mind,” although there was no significant difference on two other measures of that domain. As expected, they performed significantly worse on executive function tasks. However, the hypothesis of weak central coherence in autism was not substantiated. There was no evidence that these three cognitive impairments co-existed in individuals with autism. More likely, each of these deficits appears singly or in pair instead of forming a cluster.     

Vers une psychiatrie énactive et computationnelle

IntroductionPsychiatry is challenged by a plurality of complementary approaches. These challenges stem from the existence of multiple levels of understanding, i.e. systems of representations, tools, methodologies and objectives in psychiatry–ranging from computational approaches and systems dynamics to the multiplicity of emerging nosographies, such as the NIMH Research Domain Criteria project or staging models. In this plurality, a significant number of clinicians have adopted the biopsychosocial model. However, such a model has been widely criticized for more than twenty years. In parallel, science has declined a set of different pluralistic frameworks. Thus, through the challenges of computational modeling in psychiatry, we will see how the enactive approach of psychiatry could respond to this multiplicity. Indeed, such an enactive approach considers that perception is a (predictive) activity, which gives sense to the environment (i.e., sense making). Perception and, by extension, cognitive processes are not internal representations of the outside world, but they are deployed according to the 5E approach, i.e., an embodied, embedded, enacted, emotive and extended approach.MethodsIn this article, we first study the pluralist framework in psychiatry, in order to show its contributions in the clinical practice. Secondly, we analyze the contributions of the enactive approach for clinical practice in psychiatry.ResultsTwo forms of pluralisms can be described: a non-integrative pluralism and an integrative pluralism. The first examines the coexistence of different potentially incompatible or untranslatable systems in the scientific or clinical landscape. The second proposes the development of a general framework, bringing together the different levels of understanding and systems of representations. However, pluralism has many pitfalls and limitations. Especially by allowing computational modeling, the enactive framework, anchored both in cognitive sciences, theory of dynamic systems, systems biology and phenomenology, has recently been proposed as an answer to the challenge of integrative psychiatry.ConclusionsA significant number of mental health professionals are already working accepting such a variety of clinical and scientific approaches. We show that the enactive approach allows psychiatry: (1) to consider the subjectivity and the patient's experience, (2) to articulate different “granularities” within the clinical consultation, (3) to explain the benefits the creation of meaning for the patient, (4) to provide concrete models, (5) to support pedagogy in psychiatry. The enactive approach provides a conception for understanding psychiatric disorders as embodied, embedded, enacted, emotional and extended. In that way, the manifestations experienced by the patients are sense making experiences and can be conceived according to various levels of granularity.

The motivational process for physical activity in young adults with autism spectrum disorder

Background

Many young adults, specifically those with a diagnosis of autism spectrum disorder (ASD), do not meet the national physical activity (PA) guidelines. One way to address this problem may be to examine the factors that motivate individuals to engage in PA. However, the majority of current literature does not consider the unique characteristics of individuals with ASD, which may influence their motivation.
