Quantifying differential stimulus relatedness using the Function Acquisition Speed Test
The current research was focused on the investigation of the effectiveness of a new behaviour-analytic implicit psychological measure, the Function Acquisition Speed Test (FAST) in quantifying differential relatedness between experimental stimuli. Demonstration of the effectiveness of the measure in this regard would provide salient information to implicit measures researchers regarding the specific behavioural processes quantified by these measures, as well as providing stimulus equivalence researchers with a novel, continuous measure of differential relatedness. Experiment 1 (n = 62) investigated the effectiveness of the FAST in quantifying differential stimulus relatedness varied along inter-class parameters (i.e., a differing number of training iterations). Experiment 2 (n = 16) investigated FAST’s efficacy in measuring differential intra-class stimulus relatedness, with subjects completing three FASTs with stimulus pairs of varying nodal distance based on training. The FAST showed effectiveness in both experiments in detecting differences in experimentally-varied relatedness. The findings from the current experiments suggest that the FAST is an effective measure of differential stimulus relatedness, providing an empirical basis for a behaviour-analytic stimulus relatedness account of effects seen in implicit measures. As well as this, the FAST shows promise in quantifying the emergence of stimulus relations during training procedures. Overcoming the conceptual and procedural opacity of other implicit measures, the FAST may be suggested as a functionally-understood, conceptually-coherent implicit psychological measure, with great potential utility in the quantification of stimulus relatedness
The shape of belief : developing a mousetracking-based relational implicit measure
The Propositional Evaluation Paradigm (PEP) has recently shown promise as a relational implicit measure (i.e., an implicit measure which can specify how stimuli are related). Whereas the standard PEP measures response times, mousetracking is becoming increasingly popular for quantifying response competition, with distinct advantages beyond response times. Across four preregistered experiments ( N = 737), we interface the utility of the PEP method with the unique benefits of mousetracking by developing a mousetracking PEP (MT-PEP). The MT-PEP very effectively captured group-level beliefs across domains (Experiments 1–4). It produced larger effects (Experiment 3), exhibited superior predictive validity (Experiment 3), and better split-half reliability (Experiments 3–4) than the standard PEP. Both PEPs appear to be intentionally controllable, particularly the MT-PEP (Experiments 3–4). Nevertheless, the MT-PEP shows strong potential in capturing relational information and may be considered implicit in the sense of capturing fast and unaware (but not unintentional) responding
An inkblot for beliefs : the truth misattribution procedure
An increasing body of evidence shows the importance of accommodating relational information within implicit measures of psychological constructs. Whereas relational variants of the Implicit Association Test (IAT) have been proposed in the past, we put forward the Truth Misattribution Procedure (TMP) as a relational variant of the Affect Misattribution Procedure (AMP) that aims to capture implicit beliefs. Across three experiments, we demonstrate that TMP effects are sensitive to the relational information contained within sentence primes, both in the context of causal stimulus relations of a known truth value (e.g., “smoking causes cancer” vs. “smoking prevents cancer”) , as well as in the domain of gender stereotypes (e.g., “men are arrogant” vs. “men should be arrogant”). The potential benefits of the TMP are discussed
On the role of (implicit) drinking self-identity in alcohol use and problematic drinking : a comparison of five measures
OBJECTIVE: Implicit and explicit drinking self-identity appear to be useful in predicting alcohol-related outcomes. However, there are several different implicit and explicit measures which can be used to assess drinking self-identity. Some of these implicit measures can also capture relational information (e.g., I am a drinker, I should be a drinker), which might provide unique advantages. Despite the importance of having good measures of drinking self-identity, to date there has been little direct comparison of these measures. METHOD: This study (N = 358) systematically compared two commonly-used measures of drinking self-identity (one implicit and one explicit: the IAT and the ASCS) with three relational measures of implicit self-identity (the aIAT, the RRT, and the pCIT) on a range of criteria relevant to experimental and clinical alcohol researchers. RESULTS: Overall, we found mixed performances on the implicit measures. Interestingly, the aIAT which probed should-based drinking identity performed better than the standard IAT. However, the explicit measure exhibited superior performance to all other measures across all criteria. CONCLUSIONS: Our results suggest that researchers who wish to assess drinking-related self-identity and to predict alcohol-related outcomes cross-sectionally should set their focus primarily on the use (and further development) of the ASCS, rather than any of the implicit measures. Future research focusing on the ASCS should seek to investigate the generalisability of our findings to patient populations, and incorporate relational information within that procedure in order to further improve upon its already-strong utility
Synthesis of DBpin using Earth-abundant metal catalysis
The synthesis of DBpin was achieved using (EtBIP)CoCl2 or (tBuPNN)FeCl2 as pre-catalysts activated with NaOtBu. (EtBIP)CoCl2 was used as a pre-catalyst for the hydrogen isotope exchange of HBpin with D2, and (tBuPNN)FeCl2 for deuterogenolysis of B2pin2. The one-pot, tandem hydrogenolysis-hydroboration/deuterogenolysis-deuteroboration reaction of terminal alkenes could be catalysed by (tBuPNN)FeCl2 to give alkyl boronic esters
The Function Acquisition Speed Test (FAST) as a Measure of Verbal Stimulus Relations in the Context of Condom Use
The Function Acquisition Speed Test (FAST) has shown recent evidence as an effective tool for the quantification of stimulus
relatedness. The current study assessed the potential of the FAST in measuring the effects of the presentation of positively or
negatively valenced messages on relatedness between stimulus relations with regard to safe-sex behavior, namely condom use.
Fifty-one participants were assigned to one of three conditions comprised of valenced message interventions regarding the impact
of condom use on the enjoyment of sexual behavior (each condition n = 17): a positive-message condition, a negative-message
condition, or a no-message control condition. A significant Strength of Relation (SoR) score was found across positive and
negative FAST test trials in the positive-message condition only, with no significant differences in SoR scores observed for either
the Negative-message or Control conditions. These data suggest that the FAST may have utility as a sensitive behavioral tool for
measuring changes in stimulus relations concerning safe-sex behavior on the basis of brief message interventions
Regional employment and individual worklessness during the Great Recession and the health of the working-age population: cross-national analysis of 16 European countries
Studies from single countries suggest that local labour market conditions, including rates of employment, tend to be associated with the health of the populations residing in those areas, even after adjustment for individual characteristics including employment status. The aim of this study is to strengthen the cross-national evidence base on the influence of regional employment levels and individual worklessness on health during the period of the Great Recession. We investigate whether higher regional employment levels are associated with better health over and above individual level employment. Individual level data (N = 23,078 aged 15–64 years) were taken from 16 countries (Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Netherlands, Norway, Poland, Portugal, Spain, Sweden and United Kingdom) participating in the 2014 European Social Survey. Regional employment rates were extracted from Eurostat, corresponding with the start (2008) and end (2013) of the Great Recession. Health outcomes included self-reported heart or circulation problems, high blood pressure, diabetes, self-rated health, depression, obesity and allergies (as a falsification test). We calculated multilevel Poisson regression models, which included individuals nested within regions, controlling for potential confounding variables and country fixed effects. After adjustment for individual level socio-demographic factors, higher average regional employment rates (from 2008 to 2013) were associated with better health outcomes. Individual level worklessness was associated with worsened health outcomes, most strongly with poor self-rated health. In models including both individual worklessness and the average regional employment rate, regional employment remained associated with heart and circulation problems, depression and obesity. There was evidence of an interaction between individual worklessness and regional employment for poor self-rated health and depression. The findings suggest that across 16 European countries, for some key outcomes, higher levels of employment in the regional labour market may be beneficial for the health of the local population
A survey of factors associated with the successful recognition of agonal breathing and cardiac arrest by 9-1-1 call takers: design and methodology
<p>Abstract</p> <p>Background</p> <p>Cardiac arrest victims most often collapse at home, where only a modest proportion receives life-saving bystander cardiopulmonary resuscitation. As many as 40% of all sudden cardiac arrest victims have agonal or abnormal breathing in the first minutes following cardiac arrest. 9-1-1 call takers may wrongly interpret agonal breathing as a sign of life, and not initiate telephone cardiopulmonary resuscitation instructions. Improving 9-1-1 call takers' ability to recognize agonal breathing as a sign of cardiac arrest could result in improved bystander cardiopulmonary resuscitation and survival rates for out-of-hospital cardiac arrest victims.</p> <p>Methods/Design</p> <p>The overall goal of this study is to design and conduct a survey of 9-1-1 call takers in the province of Ontario to better understand the factors associated with the successful identification of cardiac arrest (including patients with agonal breathing) over the phone, and subsequent administration of cardiopulmonary resuscitation instructions to callers. This study will be conducted in three phases using the Theory of Planned Behaviour. In Phase One, we will conduct semi-structured qualitative interviews with a purposeful selection of 9-1-1 call takers from Ontario, and identify common themes and belief categories. In Phase Two, we will use the qualitative interview results to design and pilot a quantitative survey. In Phase Three, a final version of the quantitative survey will be administered via an electronic medium to all registered call takers in the province of Ontario. We will perform qualitative thematic analysis (Phase One) and regression modelling (Phases Two and Three), to determine direct and indirect relationship of behavioural constructs with intentions to provide cardiopulmonary resuscitation instructions.</p> <p>Discussion</p> <p>The results of this study will provide valuable insight into the factors associated with the successful recognition of agonal breathing and cardiac arrest by 9-1-1 call takers. This will guide future interventional studies, which may include continuing education and protocol changes, in order to help increase the number of callers appropriately receiving cardiopulmonary resuscitation instructions, and save the lives of more cardiac arrest victims.</p> <p>Trial registration</p> <p>Clinicaltrials.gov NCT00848588</p
Do obesity-promoting food environments cluster around socially disadvantaged schools in Glasgow, Scotland?
Increase in the consumption of food and drinks outside the home by adolescents and young people and associations with rising levels of obesity is a significant concern worldwide and it has been suggested that the food environment around schools may be a contributory factor. As few studies have explored this issue in a UK setting, we examined whether different types of food outlets are clustered around public secondary schools in Glasgow, and whether this pattern differed by social disadvantage. We found evidence of clustering of food outlets around schools but a more complex picture in relation to deprivation was observed. Across all schools there were numerous opportunities for pupils to purchase energy dense foods locally and the implications for policy are discussed
Creative destruction in science
Drawing on the concept of a gale of creative destruction in a capitalistic economy, we argue that initiatives to assess the robustness of findings in the organizational literature should aim to simultaneously test competing ideas operating in the same theoretical space. In other words, replication efforts should seek not just to support or question the original findings, but also to replace them with revised, stronger theories with greater explanatory power. Achieving this will typically require adding new measures, conditions, and subject populations to research designs, in order to carry out conceptual tests of multiple theories in addition to directly replicating the original findings. To illustrate the value of the creative destruction approach for theory pruning in organizational scholarship, we describe recent replication initiatives re-examining culture and work morality, working parents\u2019 reasoning about day care options, and gender discrimination in hiring decisions.
Significance statement
It is becoming increasingly clear that many, if not most, published research findings across scientific fields are not readily replicable when the same method is repeated. Although extremely valuable, failed replications risk leaving a theoretical void\u2014 reducing confidence the original theoretical prediction is true, but not replacing it with positive evidence in favor of an alternative theory. We introduce the creative destruction approach to replication, which combines theory pruning methods from the field of management with emerging best practices from the open science movement, with the aim of making replications as generative as possible. In effect, we advocate for a Replication 2.0 movement in which the goal shifts from checking on the reliability of past findings to actively engaging in competitive theory testing and theory building.
