Quine on Hume and the Analytic/Synthetic Distinction

W. V. O. Quine’s assault on the analytic/synthetic distinction is one of the most celebrated events in the history of twentieth century philosophy. This paper shines a light on Quine’s own understanding of the history of this distinction. More specifically, this paper argues, contrary to what seems to be the received view, that Quine explicitly recognized a kindred subversive spirit in David Hume.     

Categorization and communication in the face of prejudice: when describing perceptions changes what is perceived

In the face of prejudice against an ingroup, common ground for communication exists when people use similar social categories to understand the situation. Three studies tested the hypothesis that describing perceptions of prejudice can fundamentally change those perceptions because communicators account for the common ground in line with conversational norms. When women (Study 1), African Americans (Study 2), and Americans (Study 3) simply thought about suspected prejudice against their ingroup, categorization guided their perceptions: Participants assimilated their views of the prejudiced event toward the perceptions of ingroup members but contrasted away from the perceptions of outgroup members. Conversely, when participants described their perceptions, they contrasted away from the given category information and actually arrived at the opposite perceptions as those who merely thought about the prejudiced event. Study 3 identified an important qualification of these effects by showing that they were obtained only when participants could assume their audience was familiar with the common ground. Implications are discussed for understanding the role of communication in facilitating and inhibiting collective action about prejudice.     

Velocity-based motion categorization by pigeons

To examine if animals could learn action-like categorizations in a manner similar to noun-based categories, eight pigeons were trained to categorize rates of object motion. Testing 40 different objects in a go/no-go discrimination, pigeons were first trained to discriminate between fast and slow rates of object rotation around their central y-axis. They easily learned this velocity discrimination and transferred it to novel objects and rates. This discrimination also transferred to novel types of motions including the other two axes of rotation and two new translations around the display. Comparable tests with rapid and slow changes in the objects' size, color, and shape failed to support comparable transfer. This difference in discrimination transfer between motion-based and property-based changes suggests the pigeons had learned motion concept rather than one based on change per se. The results provide evidence that pigeons can acquire an understanding of motion-based actions, at least with regard to the property of object velocity. This may be similar to our use of verbs and adverbs to categorize different classes of behavior or motion (e.g., walking, jogging, or running slow vs. fast).     

Governing drug use through neurobiological subject construction: The sad loss of the sociocultural

Based on their "drugs as instruments" framework, Müller & Schumann (M&S) propose a staged drug policy that matches well the neoliberal governance scheme. To mend the sad loss of the sociocultural dimension in their model, I propose three such considerations: first, sociocultural interactions with the brain; second, sociocultural context and justice of drug use; and third, sociocultural preparedness for implementing their drug policy.     

Therapeutic alliance and progress in couple therapy: multiple perspectives

Therapeutic alliance research in couple therapy using multiple perspectives and longitudinal data has been sparse. This study used structural equation modelling to explore relationships between changes in alliance and in progress from clients' and therapists' perspective in a fairly large sample of couples (N=195) during the initial stage of therapy at an on‐campus training clinic. Self‐rated alliance was measured after sessions 2 through 4 with the Working Alliance Inventory. There was very little change in alliance over the early sessions of therapy, and changes in alliance did not always account for changes in relationship satisfaction. Husbands' perceptions of satisfaction and alliance seem to play an important role in the dynamics of the therapeutic process. Findings suggest a reciprocal relationship between perceptions of alliance and progress in therapy when combining perceptions of therapists and couple clients. Clinical implications and future research are discussed.     

Essential kinematic information,athletic experience,and affordance perception for others

The present study investigated the role of different types of movement in affordance perception, as well as the influence of sports experience. Perception of another actor’s maximum vertical jumping height and horizontal long-jumping distance was evaluated for basketball players, soccer players, and nonplayer controls after viewing point-light representations of the actors’ movements. Perceptual reports were more accurate after jumping-related movements (walking and squatting) were viewed than after nonrelated movements (standing and twisting). Vertical jump reports were more accurate than horizontal jump reports. Basketball and soccer players demonstrated higher accuracy than did controls. This research establishes that point-light displays contain essential kinematic information sufficient to support accurate affordance perception, and athletes appear better attuned to kinematic information specifying affordances for others as a result of their sports experience.     

On the importance of being first: Serial order effects in the interaction between action plans and ongoing actions

When we plan sequences of actions, we must hold some elements of the sequence in working memory (WM) while we execute others. Research shows that execution of an action can be delayed if it partly overlaps (vs. does not overlap) with another action plan maintained in WM (partial repetition cost). However, it is not known whether all features of the action maintained in WM interfere equally with current actions. Most serial models of memory and action assume that interference will be equal, because all action features in the sequence should be activated to an equal degree in parallel; others assume that action features earlier in the sequence will interfere more than those later in the sequence, because earlier features will be more active. Using a partial repetition paradigm, this study examined whether serial position of action features in action sequences maintained in WM have an influence on current actions. Two stimulus events occurred in a sequence, and participants planned and maintained an action sequence to the first event (action A) in WM while executing a speeded response to the second event (action B). Results showed delayed execution of action B when it matched the first feature in the action A sequence (partial repetition cost), but not when it matched the last feature. These findings suggest that serial order is represented in the action plan prior to response execution, consistent with models that assume that serial order is represented by a primacy gradient of parallel feature activation prior to action execution.
