Assembling Agency: Expression,Action, and Ethics in Deleuze and Guattari’s A Thousand Plateaus

In response to several problems identified in the primary and secondary literature, this article advances an “expressive” conception of action and agency that (i) is consistent with the metaphysics of Deleuze and Guattari’s A Thousand Plateaus, (ii) can underpin the ethical dimensions of this text, and (iii) meets some of the general requirements of a philosophy of action. This conception will be distinguished from standard theories in the philosophy of action, to the extent that these latter conceptualize and explain action with reference to intentions taken as psychological causes that are specifiable in advance and independently of the resultant activity. But it will also be distinguished from commentaries that, after rightly identifying the standard conception of intentional action as incompatible with Deleuze and Guattari’s metaphysics, fail to substitute a viable conception of action and agency in its stead. In short, drawing on a notion of expression, this article will advance a conception of intentions that does not treat them as prior and independently specifiable causes of action, but rather as “immanent” causes whose intelligible content is inseparable from—that is, dynamically assembled and specified within—the ecologically and socially situated, temporally extended and reality-transforming actions they animate.     

The effect of shopping channel (online vs. offline) on message framing of naturalness

Naturalness is a significant driver of food-related choices. However, there is scarce knowledge of how textual cues could be utilised to enhance the effectiveness of naturalness claims. Drawn from construal level theory, we attempted to examine how different methods of framing naturalness affect consumers in online vs. offline shopping contexts. Study 1 employed a 2 (abstract vs. concrete) × 2 (online vs. offline) experiment with 127 respondents and demonstrated that concrete framing heightens positive attitudes via increased perceived concreteness of the message, especially in offline shopping situations. Study 2 employed a 4 (abstract vs. control vs. concrete without mentioning natural vs. concrete mentioning natural) × 2 (online vs. offline) experiment with 173 respondents and replicated findings from Study 1. Furthermore, Study 2 ruled out alternative explanations of message authenticity, transparency and credibility and indicated that the effect of message framings is truly driven by the congruency between consumers' construal level and message framings. Interestingly, no significant effect of abstractly framed naturalness claims was observed in online shopping situations, contradicting existing studies. This suggests that other psychological mechanisms may interplay and hinder the effectiveness of abstract framing in our study. Taken together, the current research demonstrate that consumers' mental representation varies across shopping platforms and how it affects their evaluation of different methods of message framing.     

Infants and toddlers discriminate amount: are they measuring?

Four experiments that show an early ability to encode and retain information about extent are presented. We found that infants discriminate between the heights of dowels in a habituation task. We also found that toddlers discriminate between heights on a choice task in which a target dowel is presented and removed and they then choose between the target and a foil. Until 4 years of age, however, discrimination occurs only in the presence of a perceptually salient standard. Adults do not require a perceptually present standard; they can assess extent across temporal or spatial gaps by imposing a standard (measure). The present findings indicate that infants and toddlers do not possess an adult ability to establish extent, but that they do possess a skill that provides a start point for this important intellectual achievement.     

Reliability,stability, and factor structure of the Bulimia Test-Revised and Eating Disorder Inventory-2 scales in adolescence

The Eating Disorder Inventory-2 (EDI-2) and Bulimia Test-Revised (BULIT-R) have demonstrated strong reliability and validity in college students and adults. Although used in adolescent samples, little is known about the psychometric properties of these measures for adolescents. The reliability, factor structure, and mean levels of five EDI-2 scales and the BULIT-R were evaluated over 3 years. Data were collected yearly from two samples of adolescent females, one recruited from three public middle schools (n = 239, mean baseline age = 12.8) and one from two public high schools (n = 119, mean baseline age = 15.9). Results provide strong evidence for the reliability and stability of these measures. Mean levels of both measures appeared remarkably consistent over the 3 years. These results provide evidence of good psychometric performance for these scales in adolescence. The lack of change in these measures raises questions about the developmental trajectory of these variables through adolescence.     

Potential moral stigma and reactions to sexually transmitted diseases: evidence for a disjunction fallacy

Five experiments demonstrate how potential moral stigma leads people to underplay their susceptibility to sexually transmitted diseases (STDs) and dampens their interest in getting tested. After adding unprotected sex to a list of otherwise innocuous possible vectors for a disease, the authors found that infected people were perceived to be less moral (Experiment 1a), and individuals believed that if they had the disease, others would see them as less moral too (Experiment 1b). Adding this stigmatized vector also reduced reported testing intentions (Experiment 2) and perceived risk of exposure (Experiment 3)--a disjunction fallacy because adding a potential cause reduced estimated likelihood, in violation of basic probability rules. Finally, the authors replicated the effect in a computer virus analog (Experiment 4) and showed that it did not result from simply knowing that one has not engaged in the stigmatized behavior. Results suggest that avoidance of potential stigma can have dramatic health consequences, both for an individual's health decision and for health policy.     

Driving after use of alcohol and marijuana in college students.

Driving after use of marijuana is almost as common as driving after use of alcohol in youth (P. M. O'Malley & L. D. Johnston, 2003). The authors compared college students' attitudes, normative beliefs and perceived negative consequences of driving after use of either alcohol or marijuana and tested these cognitive factors as risk factors for substance-related driving. Results indicated that youth perceived driving after marijuana use as more acceptable to peers and the negative consequences as less likely than driving after alcohol use, even after controlling for substance use. Results of zero-inflated Poisson regression analyses indicated that lower perceived dangerousness and greater perceived peer acceptance were associated with increased engagement in, and frequency of, driving after use of either substance. Lower perceived likelihood of negative consequences was associated with increased frequency for those who engage in substance-related driving. These results provide a basis for comparing how youth perceive driving after use of alcohol and marijuana, as well as similarities in the risk factors for driving after use of these substances.     

Coming Full Circle: A Reciprocal-Engagement Model of Genetic Counseling Practice

As genetic health care and genetic testing expand from primarily addressing conditions that are exclusively genetic in nature to common diseases with both genetic and environmental components, the scope of genetic counseling has grown. Identification and utilization of a normative model of practice defined by members of the profession is critical as genetic services become more commonplace in medical care. The purpose of this paper is to describe the results of a consensus conference convened to define a model of genetic counseling practice based on the guidance of educators and leaders in the profession. Twenty-three program directors or their representatives from 20 genetic counseling graduate programs in North America listened to presentations and participated in group discussions aimed at determining the elements of a model of practice, including tenets, goals, strategies, and behaviors for addressing patients’ genetic concerns. Their discussion is summarized, training implications and research recommendations are presented, and a model of practice that extends their ideas is proposed.
