A case for a duty to feed the hungry: GM plants and the third world

This article is concerned with a discussion of the plausibility of the claim that GM technology has the potential to provide the hungry with sufficient food for subsistence. Following a brief outline of the potential applications of GM in this context, a history of the green revolution and its impact will be discussed in relation to the current developing world agriculture situation. Following a contemporary analysis of malnutrition, the claim that GM technology has the potential to provide the hungry with sufficient nourishment will be discussed within the domain of moral philosophy to determine whether there exists a moral obligation to pursue this end if and only if the technology proves to be relatively safe and effective. By using Peter Singer's duty of moral rescue, I argue that we have a moral duty to assist the third world through the distribution of such GM plants. I conclude the paper by demonstrating that my argument can be supported by applying a version of the Precautionary Principle on the grounds that doing nothing might be worse for the current situation.     

Compensating for Innovation: Extreme Product Incongruity Encourages Consumers to Affirm Unrelated Consumption Schemas

New products are often extremely incongruent with expectations. The inability to make sense of these products elevates anxiety and leads to negative evaluations. Although scholars have predominantly focused on combating the negative response to extreme incongruity, we propose that extreme incongruity may have implications that extend beyond the category. We base our predictions on the concept of fluid compensation, which suggests that when people struggle to make sense of something, they will nonconsciously reinforce highly accessible schemas in unrelated domains. Four studies confirm that extreme incongruity encourages fluid compensation, such that it elevates preference for dominant brands (study 1), green consumption (studies 2 and 4), and ethnocentric products (study 3). We isolate the causal role of anxiety using moderation tasks and biometric feedback. Furthermore, we demonstrate that compensation has an immediate dampening effect on arousal intensity. Thus, if consumers can compensate before explicitly evaluating an extremely incongruent product, their evaluations tend not to be negative. Taken together, we document that extreme innovations encourage compensation, and in compensating, consumers can become more receptive to extreme innovations.     

The Impact of Stimuli Color in Lexical Decision and Semantic Word Categorization Tasks

In two experiments, we examined the impact of color on cognitive performance by asking participants to categorize stimuli presented in three different colors: red, green, and gray (baseline). Participants were either asked to categorize the meaning of words as related to the concepts of “go” or “stop” (Experiment 1) or to indicate if a neutral verbal stimulus was a word or not (lexical decision task, Experiment 2). Overall, we observed performance facilitation in response to go stimuli presented in green (vs. red or gray) and performance inhibition in response to go stimuli presented in red. The opposite pattern was observed for stop‐related stimuli. Importantly, results also indicated that color might also be used to categorize neutral stimuli. Overall, these findings provide support to the green‐go and red‐stop color associations and test the potential functional autonomy acquired by these colors and the boundary conditions to their effects on stimuli categorization.     

Seeing the world through GREEN‐tinted glasses: Green consumption values and responses to environmentally friendly products

The primary goal of this research is to conceptualize and develop a scale of green consumption values, which we define as the tendency to express the value of environmental protection through one's purchases and consumption behaviors. Across six studies, we demonstrate that the six-item measure we develop (i.e., the GREEN scale) can be used to capture green consumption values in a reliable, valid, and parsimonious manner. We further theorize and empirically demonstrate that green consumption values are part of a larger nomological network associated with conservation of not just environmental resources but also personal financial and physical resources. Finally, we demonstrate that the GREEN scale predicts consumer preference for environmentally friendly products. In doing so, we demonstrate that stronger green consumption values increase preference for environmentally friendly products through more favorable evaluations of the non-environmental attributes of these products. These results have important implications for consumer responses to the growing number of environmentally friendly products.     

Cutting the silence: initial,impulsive self-cutting in adolescence

The paper explores initial, impulsive self-cutting in adolescence and conceives of early cutting as having the most potential for a communicative function, as the adolescents themselves and those around them may be most shocked at their self-harm. The author also conceives of the symptom of early, initial cutting as an effort to ‘cut through’ an emotional and familial circumstance that has been silent, suggesting that cutting generally implies a failure in containment and symbolisation. Using Green’s (1975) discussion of the original word symbol as ‘an object cut in two, constituting a sign of recognition when those who carry it can assemble the two pieces’ (Dictionnaires Le Robert), the author demonstrates that cutting has the potential to elicit intense feelings in the analyst who can have (in Green’s terms) a homologous experience to that of the patient. This elaboration within the analyst’s feelings returns a part to the patient. The meeting of the two communications (the patient’s cutting and the elaboration in the analyst’s mind) can create a potential space between them. The paper uses clinical vignettes and extended clinical material from a 16-year-old girl to elucidate the relationship between cutting – an emotionally inarticulate state – and the development of communication, containment and symbolisation through homologous experiences in the analyst.     

Preference as a function of the correlation between stimuli and reinforcement outcomes

Pigeons' preferences for stimuli that were to varying degrees correlated with outcomes were studied in two experiments using a concurrent-chain procedure. The pigeons chose between two terminal links, each ending with food reinforcement and with blackout on half of the trials. In the first experiment, one terminal link (nonpredictive or unreliable link) provided stimuli completely uncorrelated with the outcomes while the other terminal link (predictive or reliable link) provided stimuli that were, to varying degrees, correlated with these outcomes. All pigeons showed increasing preferences for the predictive link as the reliability of the stimuli in that link increased. In the second experiment, stimuli in both terminal links were differentially correlated with the outcomes. The pigeons again preferred the more reliably correlated terminal link. The relation between these results and the delay-reduction hypothesis and conditioned reinforcement account is noted. The behavioral value of predictive stimuli may lie in their permitting the organism to more effectively apportion its time between interim activities and terminal responses.     

Perceptual similarity of mirror images in infancy

Perception of mirror images by three-to four-month infants was studied in five experiments using habituation paradigms. In the first experiment, babies discriminated right profiles of two different faces but not the left and right profile of the same face. In the second, babies discriminated a 45° oblique from a vertical line, but not the oblique from its mirror image. In the third, babies discriminated oblique lines that differed by 50° and were not mirror images. In the final experiments. 90° rotations of a ?-shape were discriminated but not 180° rotations that formed lateral or vertical mirror images. These results demonstrated that although babies were able to discriminate differences in orientation (even among obliques) they tended to view mirror images, especially lateral mirror images, as equivalent stimuli. We propose that the perceptual equivalence of mirror images reflects an adaptive mode of visual processing; mirror images in nature are almost always aspects of the same object, and they usually need not be discriminated. The relations of the perceptual similarity of mirror images to the ontogeny of the object concept and to the development of reading are discussed.
