Traditionally, behavior analysts have studied stimulus equivalence using a matching‐to‐sample (MTS) preparation. Although researchers have shown the utility of MTS to yield equivalence classes, the procedure requires several prerequisite skills for a learner to accurately respond. Previous research with humans and nonhumans has shown that relational responding can be produced via compound stimulus discrimination and successive matching‐to‐sample (S‐MTS). We conducted four experiments with college students to further evaluate the effectiveness of S‐MTS in the establishment of stimulus relations. S‐MTS trials consisted of the presentation of a single sample stimulus followed by one comparison in a fixed location on a computer screen. Depending upon the sample–comparison relation, participants touched (i.e., go) or did not touch (i.e., no‐go) the comparison stimulus. Following training of the baseline relations (AB/BC), we assessed the emergence of symmetry, transitivity, and equivalence performances (i.e., BA/CB and AC/CA). Results support the utility of the S‐MTS procedure as a possible alternative to traditional MTS. This study has direct implications for participants for whom traditional three‐array MTS procedures may be challenging. 相似文献
Beginning from the proposition that doing transdisciplinary child and youth care (CYC) entails an ethic of risk and vulnerability, four graduate students from differing social, spiritual, bodied, and academic locations trace how our research and professional projects encounter, challenge, support, and disrupt one another. Thinking through two concepts critical to the field of CYC in Canada (politics and care), we aim to (a) make visible the possibilities, tensions, and incommensurabilities that emerge when we collectively risk generous, rigorous dialogue between distinct research projects, practice orientations, and lived ontological and epistemological loyalties; and (b) imagine the practices required to enact, and the creative collaborations that might emerge through, transdisciplinary conversations in child and youth care. 相似文献
Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.
Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.
Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.
Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.
Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area. 相似文献
Prior research has shown that exposure to alcohol‐related images exacerbates expression of implicit racial biases, and that brief exposure to alcohol‐related words increases aggressive responses. However, the potential for alcohol cue exposure to elicit differential aggression against a Black (outgroup) relative to a White (ingroup) target—that is, racial discrimination—has never been investigated. Here, we found that White participants (N = 92) exposed to alcohol‐related words made harsher judgments of a Black experimenter who had frustrated them than participants who were exposed to nonalcohol words. These findings suggest that exposure to alcohol cues increases discriminatory behaviors toward Blacks. 相似文献
Realists about universals face a question about grounding. Are things how they are because they instantiate the universals they do? Or do they instantiate those universals because they are how they are? Take Ebenezer Scrooge. You can say that (i) Scrooge is greedy because he instantiates greediness, or you can say that (ii) Scrooge instantiates greediness because he is greedy. I argue that there is reason to prefer the latter to the former. I develop two arguments for the view. I also respond to some concerns one might have about the view defended. I close by showing that analogous views regarding the truth of propositions (that if the proposition that p is true, then it is true because p) and the existence of facts (that if the fact that p exists, then it exists because p) are supported by analogs of one of these arguments. 相似文献
Military spouses often have concerns regarding the impact of their communication on soldiers during deployment. However, literature is mixed regarding how communication between soldiers and spouses may impact soldiers’ self-reported work functioning during deployment, suggesting the need to evaluate moderating factors. In the current study, 3 relationship factors (marital satisfaction, conflictual communication, and proportion of conversation focused on problems) were tested as moderators of communication frequency and negative marriage-to-work spillover for soldiers. Whereas the 3 relationship factors were independently related to negative spillover, none significantly moderated the relationship between communication frequency and spillover. The overall pattern of results suggests that (a) lower marital satisfaction, a focus on problems during communication, and conflictual communication are each strongly linked to spillover for deployed soldiers; and (b) military couples may be self-restricting deployment communication frequency when experiencing less marital satisfaction and higher rates of negative communication. Implications for communication during deployment are discussed. 相似文献
Misinformation can have a negative impact on decision making. Little empirical attention has, however, been given to the effect of rumors, a type of misinformation, on person judgments. Although rumors have been shown to affect other areas of organizational functioning (e.g., corporate reputation, employee morale), there is a lack of research investigating how rumors may influence hiring decisions. This study argues why rumors may influence hiring decisions by drawing from attribution, social judgment, and judgment and decision making theories, and provides an experimental investigation of this argument. Although participants reported not believing and being less likely to use the rumor, rumors were not discounted when determining if an individual should be hired. In short, results suggest that rumors impacted hiring decisions. 相似文献
