Application of the ex-Gaussian function to the effect of the word blindness suggestion on Stroop task performance suggests no word blindness.
No full textThe aim of the present paper was to apply the ex-Gaussian function to data reported by Parris et al. (2012) given its utility in studies involving the Stroop task. Parris et al. showed an effect of the word blindness suggestion when Response-Stimulus Interval (RSI) was 500 ms but not when it was 3500 ms. Analysis revealed that: (1) The effect of the suggestion on interference is observed in μ, supporting converging evidence indicating the suggestion operates over response competition mechanisms; and, (2) Contrary to Parris et al. an effect of the suggestion was observed in μ when RSI was 3500 ms. The reanalysis of the data from Parris et al. (2012) supports the utility of ex-Gaussian analysis in revealing effects that might otherwise be thought of as absent. We suggest that word reading itself is not suppressed by the suggestion but instead that response conflict is dealt with more effectively
Task conflict in the Stroop task: When Stroop interference decreases as Stroop facilitation increases in a low task conflict context.
No full textIn the present study participants completed two blocks of the Stroop task, one in which the response-stimulus interval (RSI) was 3500 ms and one in which RSI was 200 ms. It was expected that, in line with previous research, the shorter RSI would induce a low Task Conflict context by increasing focus on the color identification goal in the Stroop task and lead to a novel finding of an increase in facilitation and simultaneous decrease in interference. Such a finding would be problematic for models of Stroop effects that predict these indices of performance should be affected in tandem. A crossover interaction is reported supporting these predictions. As predicted, the shorter RSI resulted in incongruent and congruent trial reaction times (RTs) decreasing relative to a static neutral baseline condition; hence interference decreased as facilitation increased. An explanatory model (expanding on the work of Goldfarb and Henik, 2007) is presented that: (1) Shows how under certain conditions the predictions from single mechanism models hold true (i.e., when Task conflict is held constant); (2) Shows how it is possible that interference can be affected by an experimental manipulation that leaves facilitation apparently untouched; and (3) Predicts that facilitation cannot be independently affected by an experimental manipulation
Boston: Quincy Market
No full textQuincy Market is a 19th century granite building in the Greek Revival Style and is part of the Faneuil Hall Marketplace. Quincy Market is American architect Alexander Parris’ most famous building and is made of New England granite. The Quincy Market fell into decline in the 20th century until it was redeveloped in the 1970s by Rouse Company and Benjamin Thompson and Associates.https://digitalcommons.ric.edu/smolski_images/2095/thumbnail.jp

Boston: Quincy Market
No full textBoston’s Quincy Market, a 19th century marketplace built in the Greek Revival style. It is American architect Alexander Parris’ most famous building, and is made almost entirely of granite from New England. The Quincy Market fell into decline in the 20th century until it was redeveloped in the 1970s by Rouse Company and Benjamin Thompson and Associates. It continues to sell food, but also houses retail and entertainment facilities. This photograph dates from the mid 1980s.https://digitalcommons.ric.edu/smolski_images/1627/thumbnail.jp

The Role of Frontal Executive Functions in Hypnosis and Hypnotic Suggestibility
No full textThere is both theoretical and empirical evidence supporting a role for frontal executive functions (FEFs) in hypnosis and hypnotic suggestibility. However, the precise nature of this involvement is debated. While there is clear evidence that FEFs are impaired under hypnosis, the cause of this decreased function is unclear. Theories make differing predictions as to the role of FEFs in hypnotic suggestibility, with some arguing that decreased baseline (normal function outside of the hypnotic context) FEFs lead to greater hypnotic suggestibility and others arguing that increased baseline FEFs lead to greater hypnotic suggestibility. Other theories posit that suggestibility is more a consequence of attitude rather than aptitude. The present work provides a critical review of the involvement of FEFs in hypnosis and hypnotic suggestibility. The review considers behavioral evidence from studies employing putative frontal lobe tasks including tests of fluid intelligence and both task- and nontask-based neuroimaging evidence. It is determined that the evidence to date is inconclusive and that more work is needed to establish a necessary and sufficient role for FEFs in hypnosis or hypnotic suggestibility. Recommendations are made for future research
Two-to-one color-response mapping and the presence of semantic conflict in the Stroop task.
No full textA series of recent studies have utilized the two-to-one mapping paradigm in the Stroop task. In this paradigm, the word red might be presented in blue when both red and blue share the same-response key (same-response trials). This manipulation has been used to show the separate contributions of (within) semantic category conflict and response conflict to Stroop interference. Such results evidencing semantic category conflict are incompatible with models of the Stroop task that are based on response conflict only. However, the nature of same-response trials is unclear since they are also likely to involve response facilitation given that both dimensions of the stimulus provide evidence toward the same-response. In this study we explored this possibility by comparing them with three other trial types. We report strong (Bayesian) evidence for no statistical difference between same-response and non-color word neutral trials, faster responses to same-response trials than to non-response set incongruent trials, and no differences between same-response vs. congruent trials when contingency is controlled. Our results suggest that same-response trials are not different from neutral trials indicating that they cannot be used reliably to determine the presence or absence of semantic category conflict. In light of these results, the interpretation of a series of recent studies might have to be reassessed
Training community health nurses to measure parent–child interaction: a mixed-methods study
No full text© 2019 The Author(s) 2019. Published by Oxford University Press on behalf of the European Public Health Association. Background: This study aims to determine whether the Parental Responsiveness Rating Scale (PaRRiS) completed at child age 24-30 months can be used by community child health nurses (CCHNs) to reliably measure the quality of parent-child interactions in practice. Methods: A mixed-methods design was used involving CCHNs working in public health settings. Five CCHNs recruited from the North-East of England were trained to use PaRRiS. Thirty parent-child dyads attending their routine 24-30-month check were observed. Nurses rated parent-child dyads during 5 min of free-play using PaRRiS. The free-play sessions were video recorded and rated blind by the first author to the nurse observation. Semi-structured phone interviews were conducted with the five CCHNs once observations of parent-child interactions were complete. Interviews were audio-recorded, transcribed, anonymized and thematically analyzed. Results: Two-thirds of participating parents were mothers. Half the families (15/30) were from the 10% most deprived areas based on the English Index of Multiple Deprivation. The average PaRRiS score was 3.03 [standard deviation (SD) = 0.8; all ratings were <5.0]. Reliability between the first author ('gold standard') and CCHNs was excellent [Intra-class correlation coefficient (ICC): 0.85; 95% confidence interval (CI): 0.67-0.93]. CCHNs found PaRRiS aligned well with current practice and was acceptable to parents. There was no evidence of a relationship between social disadvantage and PaRRiS scores. Conclusions: With further development and evaluation work, PaRRiS could potentially be incorporated into existing universal health services to provide child health nurses with an additional tool for identifying families most likely to be in need of parent-child interaction interventions
