The role of attention during retrieval in working-memory span: a dual-task study

We tested the hypothesis that retrieving target words in operation span (OSpan) involves attention-demanding processes. Participants completed the standard OSpan task and a modified version in which all equations preceded all target words. Recall took place under either full attention or easy versus hard divided-attention conditions. Recall suffered under divided attention with the recall decrement being greater for the hard secondary task. Moreover, secondary-task performance was disrupted more by the standard OSpan task than by the modified version with the hard secondary task showing the larger decrement. Finally, the time taken to start recalling the first word was considerably longer for the standard version than for the modified version. These results are consistent with the proposal that successful OSpan task performance in part involves the attention-demanding retrieval of targets from long-term memory.     

Primary or "specific" language impairment and children learning a second language

We review empirical findings from children with primary or "specific" language impairment (PLI) and children who learn a single language from birth (L1) and a second language (L2) beginning in childhood. The PLI profile is presented in terms of both language and nonlinguistic features. The discussion of L2 learners emphasizes variable patterns of growth and skill distribution in L1 and L2 which complicate the identification of PLI in linguistically diverse learners. We then introduce our research program, designed to map out common ground and potential fault lines between typically developing children learning one or two languages, as compared to children with PLI.     

The relationship between contrast sensitivity, gait, and reading speed in Parkinson's disease

Parkinson's disease (PD) results in reduced walking speed and visual difficulties, including difficulty reading (Davidsdottir, Cronin-Golomb, & Lee, 2005). PD is characterized by a reduction in dopamine, which is instrumental in determining a person's contrast sensitivity (CS). This study assessed the relationship between CS, gait (step length and walking speed), and reading speed in 18 non-demented PD volunteers with normal acuity. We found that CS correlated with walking speed (r = .57, p = .01), step length (r = .53, p = .02), and reading speed (r = .54, p = .02). Visual acuity (which has not been tied to dopamine in the same way) correlated with reading speed (r(s) = -.65, p = .004), but not with gait measures. We also assessed the contribution of age, education, and cognitive status (Shipley Institute of Living Scale) to these variables. We conclude that CS and age both play an important role in determining gait in PD, while reading speed is related to both acuity and CS, but not age.     

From Speechlessness to Presence

Spiritual direction, or the directed art of inner conversation, emerges from a psychological inflection in which we learn that radical inner otherness is the fuel of spirit. Spirit, manifesting between self and other incarnates through and in the subject, as well as through the other encountered as authentic subject. One individuates, then, by relating to the Self as a desiring subject. Moving in the direction of spirit, we push back dimension by dimension to get to one dimension. Eventually, we may encounter a numinous silence, an emptiness that is full.     

Systematic Review and Quality Appraisal of Practice Guidelines for Self‐Harm in Children and Adolescents

This study aimed to systematically identify and appraise clinical practice guidelines (CPGs) relating to the assessment and management of suicide risk and self‐harm in children and adolescents. Our research question is as follows: For young people (under 18 years old) presenting to clinical care with suicide ideation or a history of self‐harm, what is the quality of up‐to‐date CPGs? Using the PRISMA format, we systematically identified CPGs meeting our inclusion and exclusion criteria. Subsequently, two independent raters conducted appraisals of the eligible CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were then classified as “poor quality,” “minimum quality,” and “high quality” using operationally defined criteria developed a priori. We identified 10 eligible CPGs published or renewed between 2005 and May 2017. Only the long‐term management of self‐harm CPGs produced by the National Institute for Health and Care Excellence met “high‐quality” criteria. Despite multiple options of CPGs published to choose from, only one was identified as “high quality,” where bias is adequately minimized. Clinicians are advised to direct resources to implementing the “high‐quality” CPG.
