How parents introduce new words to young children: The influence of development and developmental disorders

This study documents how parents weave new words into on-going interactions with children who are just beginning to speak. Dyads with typically developing toddlers and with young children with autism spectrum disorder and Down syndrome (n = 56, 23, and 29) were observed using a Communication Play Protocol during which parents could use novel words to refer to novel objects. Parents readily introduced both labels and sound words even when their child did not respond expressively or produce the words. Results highlight both how parents act in ways that may facilitate their child's appreciation of the relation between a new word and its referent and how they subtly adjust their actions to suit their child's level of word learning and specific learning challenges.     

Measuring the validity and psychometric properties of a short form of the Hypomanic Personality Scale

The Hypomanic Personality Scale (HPS) is used to investigate hypomanic traits and risk for bipolar spectrum disorders; however, the length of the HPS (48 items) may be prohibitive for clinical research and screening purposes. Meads and Bentall (2008) developed a promising 20-item version of the HPS; however, the psychometric properties and validity of the short form have not been thoroughly examined. The present study investigated the construct validity and psychometric properties of the short HPS. A sample of 2713 non-clinically ascertained young adults was used to assess psychometric properties of the short form relative to the original scale. Two non-overlapping subsamples (n = 522; n = 145) were used to investigate the validity of the short HPS using personality and temperament questionnaires and clinical interviews of bipolar psychopathology and diagnoses. The short and original HPS generally had comparable correlations with measures of temperament, personality, impulsivity, borderline personality, grandiosity, psychosocial functioning, and alcohol use, and comparably predicted DSM bipolar and bipolar spectrum diagnoses. Overall, the short HPS was found to be both reliable and valid. However, the short HPS tended to be more strongly correlated with pathological components of hypomanic personality and less strongly correlated with exuberant and potentially adaptive aspects of the construct.     

孤独症谱系障碍者的情绪韵律识别

情绪韵律识别是从声学线索变化中提取情绪信息,进而推断他人情绪状态的过程。情绪韵律识别缺陷是孤独症谱系障碍者的一种常见表现,此缺陷会受到情绪韵律强度、字面语义、情景语境、心理声学能力和共患疾病的影响。目前,该人群情绪韵律识别缺陷的原因探析集中于心智化能力不足、社会动机缺失和经验匮乏假说等。孤独症谱系障碍者情绪韵律识别的神经机制研究主要集中于与健康人群的比较,相关发现包括情绪韵律识别的右半球优势效应、局部脑区激活增多、大脑网络连接不足和早期注意模式异常。未来,应该进一步提高实验范式的生态效度,注重孤独症个体差异因素,整合相关理论解释,并开发有效的测评工具和干预策略。     

孤独症谱系障碍者的视觉-空间工作记忆缺陷及脑机制

孤独症谱系障碍(ASD)个体存在视觉-空间工作记忆加工缺陷,主要表现在4个方面,即随认知负荷增大而缺陷加重、工作记忆容量不足、工作记忆加工过程中的注意功能失调和对刺激进行整体组织的能力缺乏。神经机制研究显示,ASD个体存在明显的额-顶工作记忆网络激活异常,以及相关脑区的脑结构、白质连接异常。另外,作为基础性的认知加工过程,ASD个体的视觉-空间工作记忆各加工环节与言语工作记忆、执行功能、社会认知等因素均存在交互影响。纵观目前研究成果,未来研究可从研究手段、机制探究和干预训练三方面入手,着眼于研究方法的生态化和多元化,揭示客体和空间工作记忆的机制分离,并着力开发更具针对性的干预训练模式。     

Teaching social play skills to adults and children with autism as an approach to building rapport

Adults with autism spectrum disorder (ASD) and no intellectual disabilities were taught to increase the social play skills of children with ASD as part of a vocational training program. Participants included 3 adults, aged 21 to 27 years, and 6 children with ASD. Probes conducted throughout the study evaluated whether play skills training affected a measure of rapport between the adult and child. Results demonstrated the effectiveness of behavioral skills training for teaching the adult participants the appropriate play skills. In addition, the children's social engagement increased. Finally, rapport probes showed that play skills training increased levels of proximity, our measure of rapport, between the adults and children.     

Emotion processing deficits in the different dimensions of psychometric schizotypy

Schizotypy refers to a personality structure indicating “proneness” to schizophrenia. Around 10% of the general population has increased schizotypal traits, they also share other core features with schizophrenia and are thus at heightened risk for developing schizophrenia and spectrum disorders. A key aspect in schizophrenia‐spectrum pathology is the impairment observed in emotion‐related processes. This review summarizes findings on impairments related to central aspects of emotional processes, such as emotional disposition, alexithymia, facial affect recognition and speech prosody, in high schizotypal individuals in the general population. Although the studies in the field are not numerous, the current findings indicate that all these aspects of emotional processing are deficient in psychometric schizotypy, in accordance to the schizophrenia‐spectrum literature. A disturbed frontotemporal neural network seems to be the critical link between these impairments, schizotypy and schizophrenia. The limitations of the current studies and suggestions for future research are discussed.     

Experiential avoidance in body dysmorphic disorder

Experiential avoidance (i.e., the attempt to avoid certain internal experiences including bodily sensations, thoughts, emotions, memories, and urges) has been studied in various psychological disorders. However, research examining experiential avoidance in individuals with body dysmorphic disorder (BDD) is limited and inconsistent. The present study compared experiential avoidance in individuals with primary BDD (n = 23) to healthy controls (n = 22). Standardized measures were used to assess baseline clinical characteristics as well as experiential avoidance. Compared to healthy controls, individuals with BDD presented with significantly greater experiential avoidance (p < .001, d = −2.51). In BDD, experiential avoidance was positively correlated with depressive symptoms (p < .01) and avoidant coping strategies (p < .01). Clinician sensitivity to experiential avoidance may serve to improve the course of treatment for BDD.     

Presidential Address: Team Science Across Disciplines: Advancing CBT Research and Practice on Hoarding

This presidential address focuses on the recent history of research and practice on hoarding disorder (HD) as a potential model for coordinating interdisciplinary teams of professionals within and outside mental health fields to advance scientific efforts to understand and resolve mental health problems. To identify, assess, and intervene with clients who have HD, psychologists, social workers, psychiatrists, and other service professionals are needed, including those in public health, housing, medicine, aging and protective services, fire, safety, and animal protection. Research findings and practice methods developed by many of my colleagues highlight the various skills of these diverse disciplines and fields. Of particular interest are multimethod assessments and CBT interventions that span individual, group, and family treatments, delivered in the office, at home and via the web by mental health and other professionals, as well as peers. Outcomes are positive, but there remains much work to do to improve understanding and intervention outcomes.
