EPISTEMOLOGICAL CONTEXTUALISM: PROBLEMS AND PROSPECTS

Epistemological contextualism has become one of the most important and widely discussed new proposals in the theory of knowledge. This special issue contributes to the debate by bringing together some of the main participants to provide a state-of-the-art discussion of the proposal. Here we offer a brief overview of the contextualist position, describe some of the main lines of criticism that have been levelled against the view, and present a summary of each of the contributions to this collection.     

Some Worries about Normative and Metaethical Sentimentalism

In this response I raise a number of problems for Michael Slote's normative and metaethical sentimentalism. The first is that his agent–based account of rightness needs be qualified in order to be plausible; any such qualification, however, leaves Slote's normative ethics in tension with his metaethical views. The second is that an agent–based ethics of empathic caring will indeed struggle to capture our common–sense understanding of deontological constraints, and that appeal to the notion of causal immediacy will be of little help here. Finally, it seems to me that Slote's metaethical account will turn out to be much less externalist (and hence, by his own lights, much less plausible) than he suspects.     

Valuing, Desiring and Normative Priority

Judgement internalism claims that our evaluative judgements will motivate us to act appropriately, at least in so far as we are rational. I examine how this claim should be understood, with particular focus on whether valuing enjoys a kind of 'normative priority' over desiring. I consider and reject views according to which valuing something provides one with a reason to be moved; this claim of normative priority and the readings of internalism it suggests are too strong. I also reject an interpretation which eschews claims of normative priority, whilst maintaining that valuing nevertheless rationally commits or requires one to be motivated; this rejection of normative priority and the reading of internalism it supports are too weak. In the final sections I sketch the understanding of judgement internalism I favour, and defend it against objections.     

‘Sleeping beauties’: succession problems of adolescence

The author explores the succession problems of adolescence. She uses the Brothers Grimm’s fairy tale Sleeping Beauty to consider various characters and narratives possible in the analytic field during the succession process. Use of the characters in a fairy tale allows an analyst to play with the different roles the patient unconsciously assigns her. The author conceives of the avoidance of adolescent turbulence as a common reaction to adolescence, but one that can also become entrenched, and result in a restriction of emotional growth. The paper explores the psychic isolation of adolescence and the splitting required to manage the conflicting desires of the phase. The persistent absence of passion, including in the analytic process, constitutes a psychic retreat from developmental turbulence. The analyst of such an adolescent may need to allow them to be ‘somnolent’ for some time, but may eventually need to wake them (metaphorically) or even pierce the somnolent, avoidant state. The author uses clinical vignettes of late adolescents to demonstrate such transitions, exploring her countertransference experience as well as the reaction of adults to the succession process of adolescence.     

The contextual interference effect and sport skills

During the last twenty-five years, the contextual interference effect has been thoroughly studied. This review finds that the effect is relatively robust in basic research, but considerably weaker in applied settings. Motor learning scholars have urged practitioners to develop instructional strategies based upon the inferences of the contextual interference effect. The smaller effects seem to indicate that the concept may have more limited use for the physical educator. It appears that the generalization of procedures from other domains may not adequately accommodate the complexity of motor skills. Manipulating the task difficulty, both nominal and functional, and the contextual continuum may be a promising route for the practitioner.     

Statistical learning using real-world scenes: extracting categorical regularities without conscious intent

ABSTRACT— Recent work has shown that observers can parse streams of syllables, tones, or visual shapes and learn statistical regularities in them without conscious intent (e.g., learn that A is always followed by B). Here, we demonstrate that these statistical-learning mechanisms can operate at an abstract, conceptual level. In Experiments 1 and 2, observers incidentally learned which semantic categories of natural scenes covaried (e.g., kitchen scenes were always followed by forest scenes). In Experiments 3 and 4, category learning with images of scenes transferred to words that represented the categories. In each experiment, the category of the scenes was irrelevant to the task. Together, these results suggest that statistical-learning mechanisms can operate at a categorical level, enabling generalization of learned regularities using existing conceptual knowledge. Such mechanisms may guide learning in domains as disparate as the acquisition of causal knowledge and the development of cognitive maps from environmental exploration.     

Mind the gap: Misdirection, inattentional blindness and the relationship between overt and covert attention

The present commentary addresses two issues arising from Memmert’s (2010) paper. First, can the ‘misdirection’ and ‘inattentional blindness’ paradigms provide important insights into the relationship between ‘overt’ and ‘covert’ attentional processes? Second, what are the most fruitful directions for research that seeks to combine these attentional paradigms in ecologically valid settings? We argue that although Memmert’s (2010) paper postulates several important differences between the misdirection and inattentional blindness paradigms, it may not emphasise sufficiently strongly the significant insights into attention that have been yielded by the former approach. To illustrate, we discuss the utility of the misdirection paradigm in providing an ecologically valid method to investigate the relationship between overt and covert attentional processes. Such naturalistic methods are required to ensure optimal integration of the misdirection and inattentional blindness paradigms within a general theory of attention.     

Extinction of drug cue reactivity in methamphetamine-dependent individuals

Conditioned responses to drug-related environmental cues (such as craving) play a critical role in relapse to drug use. Animal models demonstrate that repeated exposure to drug-associated cues in the absence of drug administration leads to the extinction of conditioned responses, but the few existing clinical trials focused on extinction of conditioned responses to drug-related cues in drug-dependent individuals show equivocal results. The current study examined drug-related cue reactivity and response extinction in a laboratory setting in methamphetamine-dependent individuals. Methamphetamine cue-elicited craving was extinguished during two sessions of repeated (3) within-session exposures to multi-modal (picture, video, and in-vivo) cues, with no evidence of spontaneous recovery between sessions. A trend was noted for a greater attenuation of response in participants with longer (4-7 day) inter-session intervals. These results indicate that extinction of drug cue conditioned responding occurs in methamphetamine-dependent individuals, offering promise for the development of extinction- based treatment strategies.
