The influence of the visual surrounding environment in older adults and young adults’ cognitive performance: an alternative paradigm

ABSTRACT

This study investigated how the characteristics of the visual surrounding environment influence older- and young-adults’ cognitive performance. Sixty-four older adults and 64 young adults performed four visual cognitive tasks (attention and memory tasks) in two independent sessions while being exposed to a high-load and a low-load visual surrounding environment. We expected that the high-load environment would hurt the older-adults performance due to typical difficulties in ignoring irrelevant stimuli, whereas no such effect would likely occur for the young-adults whose cognitive abilities are at their best. Overall, our results were consistent with our prediction in three tasks (go/no-go, choice reaction time, and Corsi block-tapping). Additionally, the older adults performed worse than the young adults in all tasks, thus confirming expected age-related differences. Our results are consistent with those obtained when distractors and targets are presented in the same display, now using a paradigm which locates the distractors in the surrounding environment.     

情绪面孔的意识神经相关物及其无意识自动加工：来自事件相关电位的证据

意识的神经相关物尚有争议, 且个体能否无意识自动检测视觉环境变化尚不清楚。本研究采用非注意视盲范式操控视觉意识, 并引入具有社会信息的情绪面孔, 探讨意识的神经相关物以及视觉意识与自动检测变化机制的关系。在A阶段, 部分被试对任务无关的情绪面孔处于无意识水平; 在B阶段, 所有被试对任务无关的情绪面孔处于意识水平; 在C阶段, 所有被试对任务相关的情绪面孔处于意识水平。结果显示, 任务无关的情绪面孔的意识过程诱发视觉意识负波(visual awareness negativity, VAN)、晚期正成分(late positivity, LP)和晚期枕区正成分(late occipital positivity, LOP)。此外, 无意识的情绪面孔能诱发视觉失匹配负波(visual mismatch negativity, vMMN), 且其幅值不受意识影响, 但是受任务相关性调制。这些结果提示对情绪面孔的视觉意识在不同的时间进程上有不同的ERP指标——VAN反映早期知觉经验, 而LP和LOP反映晚期意识过程, 而且面孔情绪信息的自动加工独立于视觉意识, 但是受视觉注意调制。     

The effect of early life stress on the cognitive phenotype of children with an extra X chromosome (47,XXY/47,XXX)

Studies on gene–environment interactions suggest that some individuals may be more susceptible to life adversities than others due to their genetic profile. This study assesses whether or not children with an extra X chromosome are more vulnerable to the negative impact of early life stress on cognitive functioning than typically-developing children.

A total of 50 children with an extra X chromosome and 103 non-clinical controls aged 9 to 18 years participated in the study. Cognitive functioning in domains of language, social cognition and executive functioning were assessed. Early life stress was measured with the Questionnaire of Life Events. High levels of early life stress were found to be associated with compromised executive functioning in the areas of mental flexibility and inhibitory control, irrespective of group membership. In contrast, the children with an extra X chromosome were found to be disproportionally vulnerable to deficits in social cognition on top of executive dysfunction, as compared to typically-developing children. Within the extra X group the number of negative life events is significantly correlated with more problems in inhibition, mental flexibility and social cognition. It is concluded that children with an extra X chromosome are vulnerable to adverse life events, with social cognition being particularly impacted in addition to the negative effects on executive functioning. The findings that developmental outcome is codependent on early environmental factors in genetically vulnerable children also underscores opportunities for training and support to positively influence the course of development.     

From Psychical treatment to psychoanalysis: considerations on the misdating of an early Freud text and on a hitherto overlooked addition to it (here reproduced)

Freud's early paper Psychical (or mental) treatment, first published in a family reference book for educated lay persons, was reproduced in the Gesammelte Werke with a stated publication date of 1905. This date was subsequently called into question owing to certain parts of the subject-matter (the use of hypnosis and suggestion in 'mental treatment'), and the contribution was erroneously assigned, for instance by James Strachey, to the year 1890. This error is corrected in the present paper. Furthermore, the existence of a second edition of this reference book, which contains an addition to Freud's text and appeared in 1918-19, has previously gone unnoticed. The first edition had been published in 1905-6. Freud's contribution must, however, have been written at an appreciably earlier date. The probable time of its genesis is discussed. Freud's new text is reproduced (in English translation) for the first time in an appendix to this paper.     

An investigation into the possibility of an innovative treatment for weight‐related hyperphagia: Towards a more effective combination of physiological and psychological treatment for clinically obese patients who binge‐eat,category DSM IV EDNOS (Eating Disorders Not Otherwise Specified)

This paper describes Phase One of a five‐phase doctoral research inquiry into hyperphagia (eating beyond requirement) as experienced in Binge Eating Disorder (BED). It is a response to the need for a treatment plan which combines the opportunity to explore psychological reasons for overeating, as well as to understand physiological reasons for uncontrollable cravings. Three participants, recruited through local gyms, received twelve sessions of integrative counselling combining cognitive behavioural therapy and physiological information with a person‐centred approach and psychodynamic theory to help participants discover for themselves the emotional causes of their overeating. The results informed Phase Two in which a small group addressed the same issues. The outcome of both phases will be used to design a treatment programme (Phase Three) for a larger group as a pilot study (Phase Four), all phases being part of an action research project which will be evaluated in Phase Five. The study is aimed at promoting a better understanding on the part of health professionals and counsellors of the need for sufferers of BED to address emotional causes of overeating and providing such treatment in primary care. Participants in Phase One self‐reported a steady decrease in Body Mass Index (BMI) during an interval of one year and achieved an awareness of the way in which their complex relationship with food was underpinned by emotionally painful and avoidant relationships with others.     

Multiple family therapy for Chinese families of children with attention deficit hyperactivity disorder (ADHD): treatment efficacy from the children’s perspective and their subjective experiences

This paper reports the results of our study that assessed the treatment efficacy of multiple family therapy (MFT) from the perspective of participating Chinese children with attention deficit hyperactivity disorder (ADHD) and identified their subjective experiences. Forty‐three children with ADHD in the experimental group (EG) completed a forty‐two‐hour MFT, whilst forty‐five children with ADHD in the control group (CG) had attended two writing classes scheduled three months apart that were similar to those of the MFT. Data from the outcome study were gathered using standardized questionnaires and data from the qualitative study were drawn from thirteen children with ADHD who had completed the MFT and attended the focus group interviews (n = 5) or individual interviews (n = 8) conducted in the post‐treatment phase. The results of the Paired sample t‐test and MANOVA indicated no significant changes on the scores for the four measures adopted (perception of competence, hopefulness, parent‐child relationship and perceived social support) in the pre‐ and post‐treatment for the EG and the CG. Five themes emerged from the narratives of children with ADHD, which revealed the children’s subjective experiences with the MFT: (a) full of fun; (b) building friendships through common experiences; (c) a happy family time; (d) safe space; and (e) positive parental responses and communications.     

Evaluation of The Practitioner Online Referral and Treatment Service (PORTS): the first 18 months of a state-wide digital service for adults with anxiety,depression, or substance use problems

ABSTRACT

The Practitioner Online Referral and Treatment Service (PORTS) is a new digital mental health service (DMHS) providing assessment, treatment, and consultation across Western Australia, for adults with anxiety, depression, or substance use problems, and experiencing financial hardship or geographical disadvantage. From July 2017 to December 2018, a total of 2,527 individuals were referred to PORTS. Of these, 150 (6%) did not give consent for their results to be analysed. Of the remaining 2,377 patients, 615 (26%) could not be contacted to confirm the referral, 596 (25%) received assessment or information from PORTS, 427 (18%) were referred to another service, and 739 (31%) commenced treatment at PORTS. Almost half (47%) of patients were from areas with significant socio-economic disadvantage. Those referred by another mental health service were more likely to engage in treatment than those referred by a General Practitioner (GP). Overall outcomes were excellent, with large effect sizes (Cohen’s d: 1.1–1.4), from assessment to post-treatment and 3-month follow-up, reliable deterioration was low, and GP and patient satisfaction was high. These results indicate that the PORTS DMHS model is a promising method for engaging primary care patients with anxiety and depression, including those experiencing financial and geographical disadvantage.     

An illness-specific version of the Revised Illness Perception Questionnaire in patients with atrial fibrillation (AF IPQ-R): Unpacking beliefs about treatment control,personal control and symptom triggers

Objective: This study modified the Revised Illness Perception Questionnaire (IPQ-R) in patients with persistent atrial fibrillation (AF).

Design: Qualitative interviews and think-aloud techniques informed modification of the IPQ-R to be specific to AF patients. Confirmatory Factor Analysis (CFA) (n = 198) examined the validity of the modified IPQ-R (AF-IPQ-R). Exploratory factor analysis (EFA) examined the new AF-triggers scale. Construct validity examined associations between the AF-IPQ-R, quality of life (QoL) and beliefs about medicines. Test–retest and internal reliability were examined.

Results: Interviews indicated that patients viewed triggers of AF rather than initial causes of illness as more applicable. Patients believed specific behaviours such as rest could control AF. Treatment control beliefs related to pharmacological and procedural treatments. These data were used to modify the IPQ-R subscales and to develop a triggers of AF scale. CFA indicated good model fit. EFA of the triggers scale indicated three factors: emotional; health behaviours; and over-exertion triggers. Expected correlations were found between the AF-IPQ-R, QoL and treatment beliefs, evidencing good construct validity.

Conclusion: The AF-IPQ-R showed sound psychometric properties. It provides more detailed specification than the IPQ-R of beliefs that may help to understand poor QoL in AF patients, and guidance for future interventions in this area.     

Ensuring an independent future for young people with special educational needs and disabilities (SEND): a critical examination of the impact of education,health and care plans in England

This article examines the implications of the new education, health and care (EHC) planning process for career professionals in England. The new process comes in the wake of a succession of legislation relating to young people with special educational needs and disabilities (SEND) in England. There is much to recommend the new process as it represents a shift to a more holistic and person-centred approach. However, there are four main criticisms which can be made of the new process: (1) the policy has an excessive focus on paid work as an outcome which is unrealistic (for some young people); (2) the resourcing in local authorities is too limited to successfully operationalise the policy; (3) there is a lack of clarity about the professional base delivering EHC planning (especially in relation to the career elements); and (4) the policy is too narrowly targeted. While the new legislation offers some major opportunities, realising these will be difficult. In this paper, questions are raised about the resources required to deliver these services; the responsibilities relevant to such services; and the role and scope of these services in supporting the transitions of vulnerable young people into learning and work in an environment where universal careers provision has been substantially diminished.
