Boosting the Potency of Resistance: Combining the Motivational Forces of Inoculation and Psychological Reactance

The efficacy of inoculation theory has been confirmed by decades of empirical research, yet optimizing its effectiveness remains a vibrant line of investigation. The present research turns to psychological reactance theory for a means of enhancing the core mechanisms of inoculation—threat and refutational preemption. Findings from a multisite study indicate reactance enhances key resistance outcomes, including: threat, anger at attack message source, negative cognitions, negative affect, anticipated threat to freedom, anticipated attack message source derogation, perceived threat to freedom, perceived attack message source derogation, and counterarguing. Most importantly, reactance‐enhanced inoculations result in lesser attitude change—the ultimate measure of resistance.     

Judgments of average magnitude: Analyses in terms of the functional measurement and two-stage models

Subjects made magnitude estimates of the average loudness of pairs of 1,000-Hz tones varying in sound pressure. A test of fit of an averaging model employing an analysis of variance suggested that the judgments were internally consistent. However, estimates of the parameters of a two-stage model based on the assumption that power transformations were imposed in both input and output implied a nonlinear output function, inconsistent with the averaging model. Additional analyses employing a nonmetric scaling solution also suggested that output was nonlinear, indicating that this implication was not an artifact of the strong assumptions of the two-stage model. Large differences were found among the output functions of individual subjects, and it was suggested that these may have inflated the error term in the analysis of variance, reducing its power to detect violations of the additive model. Similar analyses were performed on data from judgments of average grayness collected by Weiss (1972).     

The effect of change in US quality on the blocking effect

If one CS is paired with a US and then that CS together with a “redundant” stimulus is paired with the US, conditioning of that “redundant” stimulus is attenuated or blocked. The present experiment explores the effect upon this blocking of changing the quality of the US coincident with the introduction of the redundant stimulus. Changing US quality disrupted blocking only when the US potency was also increased. Quality changes in which the redundant stimulus was correlated with a lower potency US only increased blocking. These results are taken as supporting the conditioning model of Rescorla and Wagner but inconsistent with a casual informational model of conditioning.     

Chewing Over In Vitro Meat: Animal Ethics,Cannibalism and Social Progress

Despite its potential for radically reducing the harm inflicted on nonhuman animals in the pursuit of food, there are a number of objections grounded in animal ethics to the development of in vitro meat. In this paper, I defend the possibility against three such concerns. I suggest that worries about reinforcing ideas of flesh as food and worries about the use of nonhuman animals in the production of in vitro meat can be overcome through appropriate safeguards and a fuller understanding of the interests that nonhuman animals actually possess. Worries about the technology reifying speciesist hierarchies of value are more troublesome, however. In response to this final challenge, I suggest that we should be open not just to the production of in vitro nonhuman flesh, but also in vitro human flesh. This leads to a consideration of the ethics of cannibalism. The paper ultimately defends the position that cannibalism simpliciter is not morally problematic, though a great many practices typically associated with it are. The consumption of in vitro human flesh, however, is able to avoid these problematic practices, and so should be considered permissible. I conclude that animal ethicists and vegans should be willing to cautiously embrace the production of in vitro flesh.     

Measuring Need Satisfaction and Frustration in Educational and Work Contexts: The Need Satisfaction and Frustration Scale (NSFS)

The satisfaction and frustration of the psychological needs for autonomy, relatedness and competence predict well-being and ill-being outcomes. However, research within educational and work contexts is stifled by the lack of an exhaustively validated measure. Following extensive preparatory and pilot work, the present three studies (total N = 762) aimed to develop such a measure and validate it against the Basic Need Satisfaction at Work Scale (Deci et al. in Personal Soc Psychol Bull 27(8):930–942, 2001) and an adapted version of the Balanced Measure of Psychological Needs (Sheldon and Hilpert in Motivation Emot 36(4):439–451, 2012). The Need Satisfaction and Frustration Scale demonstrated a better factor structure and internal reliability than its predecessors, and good criterion validity. This improvement was due to the exclusion of ambiguous items and items measuring antecedents of need satisfaction and frustration. The results also strengthen current evidence showing that need satisfaction and frustration are distinct but related constructs, and each better predicts well-being and psychological health problems, respectively.     

The effects of ethanol intoxication on phobic anxiety

Behavioral conceptions of alcohol abuse often include the hypothesis that drinking behavior is a negatively reinforced operant, with ethanol intoxication viewed as alleviating aversive environmental and internal states. This hypothesis has not been confirmed or refuted by previous studies which employed mild stressors and limited assessment methodology. In the present experiment, 22 patients with severe phobias approached their phobic animal under two consecutive conditions—first while sober and second after drinking either a placebo or an intoxicating dose of ethanol. The severe anxiety induced was assessed behaviorally, physiologically and by the patient's self-report of fear. The intoxicated patients did not experience decreased anxiety, tachycardia or avoidance, compared to the placebo group. These results have clinical implications and suggest the need to reconsider tension-reduction theories of alcohol abuse.
