The Way

Person perception research predominantly focuses on faces as stimuli, and less attention is paid to full body, moving, stimuli and how our perceptions of that person might affect the way we observe unknown people. Here, we present two studies and register a third. In Study One, 27 raters observed 12 videos of female targets walking towards camera for 10 seconds and rated how ‘threatening’, ‘attractive’ and ‘masculine’ the target individual was. In Study Two, 30 raters observed 22 male and female targets in the same format with the same ratings. The observation of the targets in both studies was recorded on an eyetracker and the percentage of each second spent watching the head, trunk, and legs was recorded. In both studies time spent observing the targets’ head decreased over time. In Study One perception ratings affected time spent observing the head and ratings interacted with change in observation over time. In Study Two no effects were found. Given these inconsistent findings and methodological differences between the studies, here we register a Study Three using two samples of 30 participants and Study Two’s methodology to attempt to support either of the previous studies.

One of the classic relationships in personality psychology is that extraversion is associated with emerging as an informal leader. However, recent findings raise questions about the longevity of extraverted individuals as emergent leaders. Here, we adopt a social network churn perspective to study the number of people entering, remaining in, and leaving the leadership networks of individuals over time. We propose that extraverted individuals endure as emergent leaders in networks over time, but experience significant changes in the people being led, including the loss of people who once considered them a leader but now no longer do. In Study 1 (N = 545), extraverted individuals had a larger number of new and remaining people in their leadership networks, but also lost more people, above and beyond differences in initial leadership network size. In Study 2 (N = 764), we replicated and extended these results in an organizational sample while controlling for alternative explanations such as formal rank, network size, self-monitoring, and narcissism. Extraversion predicted the number of people entering, remaining in, and leaving leadership networks over time. Our findings suggest that while extraverted individuals tend to emerge as leaders, they are also more likely to experience greater network churn—they tend to lead different people over time and leave people in their wake who once perceived them a leader but now no longer do. We discuss the challenges posed by this network churn perspective for extraverted emergent leaders and highlight its importance for our understanding of extraversion and emergent leadership.

AbstractEvolved dispositions influence, but do not determine, how people think about economic problems. The evolutionary cognitive approach offers important insights but underweights the social transmission of ideas as a level of explanation. The need for asocialexplanation for the evolution of economic attitudes is evidenced, for example, by immense variations in folk-economic beliefs over time and across individuals.

Articulatory generalization of velar cognates /k/, /g/ in two phonologically disordered children was studied over time as a function of sequential word-morpheme position training. Although patterns of contextual acquisition differed, correct responses to the word-medial, inflected context (e.g., "picking," "hugging") occurred earlier and exceeded those to the word-medial, noninflected context (e.g., "bacon," "wagon"). This finding indicates that the common view of the word-medial position as a unitary concept is an oversimplification. Possible explanations for superior generalization to the word-medial, inflected position are discussed in terms of coarticulation, perceptual salience, and the representational integrity of the word.

Purpose This study reports on the treatment fidelity procedures implemented during a 5-year randomized controlled trial comparing intensive and distributed comprehensive aphasia therapy. Specifically, the results of 1 treatment, verb network strengthening treatment (VNeST), are examined. Method Eight participants were recruited for each of 7 consecutive cohorts for a total of 56 participants. Participants completed 60 hr of aphasia therapy, including 15 hr of VNeST. Two experienced speech-language pathologists delivered the treatment. To promote treatment fidelity, the study team developed a detailed manual of procedures and fidelity checklists, completed role plays to standardize treatment administration, and video-recorded all treatment sessions for review. To assess protocol adherence during treatment delivery, trained research assistants not involved in the treatment reviewed video recordings of a subset of randomly selected VNeST treatment sessions and completed the fidelity checklists. This process was completed for 32 participants representing 2 early cohorts and 2 later cohorts, which allowed for measurement of protocol adherence over time. Percent accuracy of protocol adherence was calculated across clinicians, cohorts, and study condition (intensive vs. distributed therapy). Results The fidelity procedures were sufficient to promote and verify a high level of adherence to the treatment protocol across clinicians, cohorts, and study condition. Conclusion Treatment fidelity strategies and monitoring are feasible when incorporated into the study design. Treatment fidelity monitoring should be completed at regular intervals during the course of a study to ensure that high levels of protocol adherence are maintained over time and across conditions.

Abstract The techniques of performing a tracheostomy has transformed over time. Percutaneous tracheostomy is gaining popularity over open tracheostomy given its advantages and as a result the number of bedside tracheostomies has increased necessitating the need for a Percutaneous Tracheostomy Program. The Percutaneous Tracheostomy Program at the Johns Hopkins Hospital is a comprehensive service that provides care to patients before, during, and after a tracheostomy with a multidisciplinary approach aimed at decreasing complications. Education is provided to patients, families, and health-care professionals who are involved in the management of a tracheostomy. Ongoing prospective data collection serves as a tool for Quality Assurance.
