Multidimensional Signals and Analytic Flexibility: Estimating Degrees of Freedom in Human-Speech Analyses

Abstract Recent empirical studies have highlighted the large degree of analytic flexibility in data analysis that can lead to substantially different conclusions based on the same data set. Thus, researchers have expressed their concerns that these researcher degrees of freedom might facilitate bias and can lead to claims that do not stand the test of time. Even greater flexibility is to be expected in fields in which the primary data lend themselves to a variety of possible operationalizations.

Protocol for a Remote Webcam-based Eye-Tracking Experiment for Examining Visual Attention to Tobacco Marketing Materials

Abstract Background: Eye-tracking provides an objective way to measure attention, which can advance researchers’ and policymakers’ understanding of tobacco marketing influences. The development of remote webcam-based eye-tracking technology, integrated with online crowdsourcing studies, may be a cost-effective and time-efficient alternative to laboratory-based eye-tracking methods. However, research is needed to evaluate the utility of remote eye-tracking methods. Objective: To detail the process of designing a remote webcam-based eye-tracking experiment and provide data on associations between participant characteristics and the outcomes of completing the experiment.

The effects of group counseling and self-affirmation on stigma and group relationship development: A replication and extension.

Abstract The stigma of seeking counseling and negative attitudes about counseling are primary barriers to its use. In the only known study examining the utility of attending a group counseling session to ameliorate stigma (no control group), participation was associated with reductions in self-stigma (Wade et al., 2011). Self-affirmation interventions have shown promising results in reducing stigma and promoting positive expectations about counseling, but no research has examined its effects on a counseling session.

Validation of the Iowa test of consonant perception

Abstract Speech perception (especially in background noise) is a critical problem for hearing-impaired listeners and an important issue for cognitive hearing science. Despite a plethora of standardized measures, few single-word closed-set tests uniformly sample the most frequently used phonemes and use response choices that equally sample phonetic features like place and voicing. The Iowa Test of Consonant Perception (ITCP) attempts to solve this. It is a proportionally balanced phonemic word recognition task designed to assess perception of the initial consonant of monosyllabic consonant-vowel-consonant (CVC) words.

Intracranial EEG evidence of functional specialization for taxonomic and thematic relations

Abstract The dual-hub account posits that the neural organization of semantic knowledge is segregated by the type of semantic relation with anterior temporal lobe (ATL) specializing for taxonomic relations and inferior parietal lobule (IPL) for thematic relations. This study critically examined this account by recording intracranial EEG from an array of depth electrodes within ATL, IPL, and two regions within the semantic control network, inferior frontal gyrus (IFG) and posterior middle temporal gyrus (pMTG), while 17 participants with refractory epilepsy completed a semantic relatedness judgment task.
