Response interference between functional and structural actions linked to the same familiar object

Viewing objects with the intention to act upon them may activate task-irrelevant motor responses. Many manufactured objects are associated with two action classes: grasping in accordance with object structure and skillful use consistent with object function. We studied the potential for within-object competition during action selection by comparing initiation latencies for “conflict” objects (with competing structure and function responses) to “non-conflict” objects (with a single response). We demonstrated a novel pattern of within-object interference wherein actions involving conflict objects were slowed when participants skillfully used those objects (grasp-on-use interference) as well as a second pattern of interference when conflict objects were grasped after skillfully using the same objects in previous blocks (long-term use-on-grasp interference). These data suggest that actions to common objects are influenced by competition between rapid but briefly maintained grasp responses and slower but longer-lasting use responses, and advance our understanding of the process and neural substrates of selection for action.     

Repentance and forgiveness: the undoing of time

Mass death resulting from war, starvation, and disease as well as the vicissitudes of extreme poverty and enforced sexual servitude are recognizably pandemic ills of the contemporary world. In light of their magnitude, are repentance, regret for the harms inflicted upon others or oneself, and forgiveness, proferring the erasure of the guilt of those who have inflicted these harms, rendered nugatory? Jacques Derrida claims that forgiveness is intrinsically rather than circumstantially or historically impossible. Forgiveness, trapped in a paradox, is possible only if there is such a thing as the unforgivable. “Thus, forgiveness, if there is such a thing,” can only exist as exempt from the law of the possible. Does this claim not open the way for hopelessness and despair? More troubling for Derrida is his concession that forgiveness may be necessary in the realm of the political and juridical. If so, is not the purity of the impossibility of forgiveness so crucial for him, contaminated? In pointing to some of the difficulties in Derrida’s position, I shall appeal to Vladimir Jankelevitch’s distinction between the unforgivable and the inexcusable. I shall also consider the significance of repentance in the theological ethics of Emmanuel Levinas and Max Scheler. Forgiveness, I conclude, is vacuous without expiation, a position that can be helpfully understood in the context of Judaism’s analysis of purification and acquittal in the Day of Atonement liturgy. I argue that what disappears is Derrida’s assurance of the impossibility of forgiveness, a disappearance that allows for hope.     

The effectiveness of personalized e-mail newsletters and the role of personal characteristics

Personalizing communication means creating persuasive messages that refer to aspects of a person's self. Although the use of personalization is increasing, research on its effectiveness is limited and the results are mixed. This study examined the persuasiveness of personalized e-mail newsletters in terms of increased attention, cognitive activity, evaluation, attitude, intention, and behavior by means of an experiment (n=109). Participants randomly received either a personalized or a generic newsletter advertising a sports center. Personalization triggered a more positive evaluation of the message; however, it did not influence the other effect variables. The effects were moderated by consumers' need for uniqueness, trust, and privacy concerns, suggesting that personalization is a good strategy to increase message evaluation only among individuals who have a high need for uniqueness.     

Elite sport is not an additional source of distress for adolescents with high stress levels

This study examined whether participation in elite sport interacts with stress in decreasing or increasing symptoms of depression and anxiety among adolescents, and further, whether the interplay between participation in high-performance sport and stress is related to the perceived quality of sleep. 434 adolescents (278 girls, 156 boys; age: M = 17.2 yr.) from 15 "Swiss Olympic Sport Classes" and 9 conventional classes answered a questionnaire and completed a 7-day sleep log. Analyses of covariance showed that heightened stress was related to more depressive symptoms and higher scores for trait-anxiety. Moreover, those classified as having poor sleep by a median split cutoff reported higher levels of depressive symptoms. No significant (multivariate) main effects were found for high-performance sport athletes. Similarly, no significant two- or three-way interaction effects were found. These results caution against exaggerated expectations concerning sport participation as a stress buffer. Nevertheless, participation in high-performance sport was not found to be an additional source of distress for adolescents who reported high stress levels despite prior research that has pointed toward such a relationship.
