Purpose The purpose of this study was to investigate the perceptions of speech-language pathologists (SLPs) regarding their academic preparation and current confidence levels for providing dysphagia services, and the relationship between their perceptions of graduate school preparation and their current levels of confidence. Method This study utilized an online survey to gather information from 374 American Speech-Language-Hearing Association–certified SLPs who currently provide dysphagia services in the United States. Surveys were primarily distributed through American Speech-Language-Hearing Association Special Interest Group forums and Facebook groups. The anonymous survey gathered information regarding SLPs' perceptions of academic preparation and current confidence levels for providing dysphagia services in 11 knowledge and skill areas. Results Findings indicated that more than half of respondents did not feel prepared following their graduate academic training in five of the 11 knowledge and skill areas related to dysphagia service delivery. However, about half of respondents indicated they were currently confident about their ability to provide services in eight of the 11 knowledge and skill areas. Findings also indicated that their current confidence levels to provide dysphagia services were significantly higher than their perceptions of preparation immediately following graduate school. However, no significant relationships were found between respondents' self-reported current confidence levels and their perceptions of the adequacy of their academic preparation. Conclusions Despite SLPs' low perceptions of the adequacy of their graduate preparation for providing dysphagia services in specific knowledge and skill areas immediately following graduation, they reported high confidence levels with respect to their actual service delivery. Implications of these findings are discussed.

In a recent issue of this journal (Vol.8 no.2) the paper ‘Record linkage theory and practice: an experiment in the application of multiple pass linkage algorithms’ by Charles Harvey, Edmund Green and Penelope J. Corfield described the advances the authors have made on their previously published work. By using a multiple pass methodology they increased the linkage rate between two successive polls (1784 and 1788) from one-fifth to nearly three-fifths of the voters in the parliamentary elections for the City of Westminster. This critique examines the validity of their claims with regard to the confidence levels attained.

Confidence Ratings

Humans have the metacognitive ability to judge the accuracy of their own decisions via confidence ratings. A substantial body of research has demonstrated that human metacognition is fallible but it remains unclear how metacognitive inefficiency should be incorporated into a mechanistic model of confidence generation. Here we show that, contrary to what is typically assumed, metacognitive inefficiency depends on the level of confidence. We found that, across five different datasets and four different measures of metacognition, metacognitive ability decreased with higher confidence ratings. To understand the nature of this effect, we collected a large dataset of 20 subjects completing 2,800 trials each and providing confidence ratings on a continuous scale. The results demonstrated a robustly nonlinear zROC curve with downward curvature, despite a decades-old assumption of linearity. This pattern of results was reproduced by a new mechanistic model of confidence generation, which assumes the existence of lognormally-distributed metacognitive noise. The model outperformed competing models either lacking metacognitive noise altogether or featuring Gaussian metacognitive noise. Further, the model could generate a measure of metacognitive ability which was independent of confidence levels. These findings establish an empirically-validated model of confidence generation, have significant implications about measures of metacognitive ability, and begin to reveal the underlying nature of metacognitive inefficiency.
