Early gesture selectively predicts later language learning

The gestures children produce predict the early stages of spoken language development. Here we ask whether gesture is a global predictor of language learning, or whether particular gestures predict particular language outcomes. We observed 52 children interacting with their caregivers at home, and found that gesture use at 18 months selectively predicted lexical versus syntactic skills at 42 months, even with early child speech controlled. Specifically, number of different meanings conveyed in gesture at 18 months predicted vocabulary at 42 months, but number of gesture+speech combinations did not. In contrast, number of gesture+speech combinations, particularly those conveying sentence‐like ideas, produced at 18 months predicted sentence complexity at 42 months, but meanings conveyed in gesture did not. We can thus predict particular milestones in vocabulary and sentence complexity at age by watching how children move their hands two years earlier.     

Assessing Emotion Regulation in Social Anxiety Disorder: The Emotion Regulation Interview

Social anxiety disorder (SAD) is thought to involve emotional hyper-reactivity and emotion dysregulation. However, the precise nature of the emotion dysregulation in SAD has not been well characterized. In the present study, the Emotion Regulation Interview (ERI) was developed to quantify the frequency and self-efficacy of five emotion regulation strategies specified by Gross’s (Review of General Psychology 2: 271–299, 1998) process model of emotion regulation. Forty-eight individuals with SAD and 33 healthy controls (HCs) were interviewed about responses during (a) a laboratory speech task and (b) two recent social anxiety-evoking situations. Individuals with SAD reported greater use of avoidance and expressive suppression than HCs, as well as lesser self-efficacy in implementing cognitive reappraisal and expressive suppression. These regulation deficits were not accounted for by differences in emotional reactivity. These findings highlight specific emotion regulation deficits in SAD, and support the idea that the Emotion Regulation Interview may be usefully applied to other clinical disorders.     

Psychometric evaluation of the Fear of Positive Evaluation Scale in patients with social anxiety disorder

The Fear of Positive Evaluation Scale (FPES; J. W. Weeks, R. G. Heimberg, & T. L. Rodebaugh, 2008) was designed to assess fear of positive evaluation, a proposed cognitive component of social anxiety. Although previous findings on the psychometric properties of the FPES have been highly encouraging, only 1 previous study has examined the psychometric profile of the FPES in a sample of patients with social anxiety disorder (T. A. Fergus et al., 2009). The primary purpose of the present study was to conduct a large multisite examination of the psychometric profile of the FPES among patients with a principal diagnosis of social anxiety disorder (n = 226; generalized subtype = 97.8%). Responses of nonanxious control participants (n = 42) were also examined. The factorial validity, internal consistency, test-retest reliability, construct validity, and treatment sensitivity of the FPES were strongly supported by our findings. Furthermore, an FPES cutoff score was identified for distinguishing levels of fear of positive evaluation characteristic of patients with social anxiety disorder from those characteristic of the control group. Results provide additional support for the psychometric properties of the FPES in clinical samples.     

Heng Xian and the Problem of Studying Looted Artifacts

Heng Xian is a previously unknown text reconstructed by Chinese scholars out of a group of more than 1,200 inscribed bamboo strips purchased by the Shanghai Museum on the Hong Kong antiquities market in 1994. The strips have all been assigned an approximate date of 300 B.C.E., and Heng Xian allegedly consists of thirteen of them, but each proposed arrangement of the strips is marred by unlikely textual transitions. The most plausible hypothesis is one that Chinese scholars do not appear to take seriously: that we are missing one or more strips. The paper concludes with a discussion of the hazards of studying unprovenanced artifacts that have appeared during China’s recent looting spree. I believe the time has come for scholars to ask themselves whether their work indirectly abets this destruction of knowledge.
