When gift-giving produces dissonance: Effects of subliminal affiliation priming on choices for one's self versus close others

Past research on cognitive dissonance indicated that people from independent (e.g. European-American) and interdependent (e.g. East-Asian) cultural backgrounds show different patterns of choice justification: whereas choice made for oneself affirms the independent view of the self, choice made for close others affirms the interdependent view of the self. We hypothesized that interpersonal choice considerations may be temporally accessible even among habitually independent European-Americans. The present research provides the first experimental evidence that choice justification varies as a function of both subliminal affiliation priming and the target of choice (self vs. close others). Results from three studies indicate that subliminal priming of affiliation increases justification of a choice European-Americans made for a close other, while decreasing justification of a choice made for the self. Implications for theories related to cognitive dissonance, subliminal processing and cultural meaning systems are discussed.     

Chasin’ choppers: using unpredictable trajectories to test theories of object interception

Three theories of the informational basis for object interception strategies were tested in an experiment where participants pursued toy helicopters. Helicopters were used as targets because their unpredictable trajectories have different effects on the optical variables that have been proposed as the basis of object interception, providing a basis for determining the variables that best explain this behavior. Participants pursued helicopters while the positions of both pursuer and helicopter were continuously monitored. Using models to predict the observed optical trajectories of the helicopter and ground positions of the pursuer, optical acceleration was eliminated as a basis of object interception. A model based on control of optical velocity (COV) provided the best match to pursuer ground movements, while one based on segments of linear optical trajectories (SLOT) provided the best match to the observed optical trajectories. We describe suggestions for further research to distinguish the COV and SLOT models.     

Identity and similarity

The standard approach to the so-called paradoxes of identity has been to argue that these paradoxes do not essentially concern the notion of identity but rather betray misconceptions on our part regarding other metaphysical notions, like that of an object or a property. This paper proposes a different approach by pointing to an ambiguity in the identity predicate and arguing that the concept of identity that figures in many ordinary identity claims, including those that appear in the paradoxes, is not the traditional philosophical concept but one that can be defined in terms of relevant similarity. This approach to the paradoxes will be argued to be superior to the standard one.     

The role of testimony in young children's solution of a gravity-driven invisible displacement task

Previous research has shown that young children make a perseverative, gravity-oriented, error when asked to predict the final location of a ball dropped down an S-shaped opaque tube (Hood, 1995). We asked if providing children with verbal information concerning the role that the tubes play, in determining the ball's trajectory would improve their performance. Experiment 1 showed that performance of 3.5-year-olds improved after hearing testimony about the movement of the ball. Experiment 2 showed that the specific content of the testimony – rather than any accompanying non-verbal cues – helped children improve. These findings suggest that other people's testimony can be a valuable source of information when young children learn about the physical world. Indeed, under some circumstances children seem to benefit more from verbal than visual information. An educational implication is that it may sometimes be ineffective to focus on the impact of first-hand experience while marginalizing the role of verbal information.     

Between Academic Pimping and Moral Harassment in Higher Education: an Autoethnography in a Brazilian Public University

It is shocking to notice that universities still research few of what daily happens inside their walls. Even though knowledge amount to just a small part of the numerous things that are produced in/between academic relations, it is rare to find investigations in which academic modus operandi is the research focus. The text relies on references like Foucault, Deleuze and Guattari to investigate the subjectivities produced in Academia’s daily routines. With attention to experiences, to what many times is naturalized and said only in the corridors and behind the scenes, this paper uses autoethnography as its method with the aim of analysing academic relations in the context of a Brazilian public university. The narratives constructed here are traversed by songs, lived situations, and affectations. Stories that deal with trajectories of a professor since his arrival at a new workplace. E-mails, threats, exoneration. What is considered to be normal in Academia? What still shocks and affect us? The paper draws on concepts like moral harassment and academic pimping to guide the written narratives and to deepen analyses built throughout the paper. How is it possible to de-naturalize what we daily do in universities? Without predefined or definite answers, the text questions the ways how we relate to each other in Academia and stimulates reflections on the impacts of our academic relations, not only to work itself, but also to the lives of the involved ones.     

Visual search for changes in scenes creates long-term,incidental memory traces

Humans are very good at remembering large numbers of scenes over substantial periods of time. But how good are they at remembering changes to scenes? In this study, we tested scene memory and change detection two weeks after initial scene learning. In Experiments 1–3, scenes were learned incidentally during visual search for change. In Experiment 4, observers explicitly memorized scenes. At test, after two weeks observers were asked to discriminate old from new scenes, to recall a change that they had detected in the study phase, or to detect a newly introduced change in the memorization experiment. Next, they performed a change detection task, usually looking for the same change as in the study period. Scene recognition memory was found to be similar in all experiments, regardless of the study task. In Experiment 1, more difficult change detection produced better scene memory. Experiments 2 and 3 supported a “depth-of-processing” account for the effects of initial search and change detection on incidental memory for scenes. Of most interest, change detection was faster during the test phase than during the study phase, even when the observer had no explicit memory of having found that change previously. This result was replicated in two of our three change detection experiments. We conclude that scenes can be encoded incidentally as well as explicitly and that changes in those scenes can leave measurable traces even if they are not explicitly recalled.

Engagement in Activities Is Associated With Affective Arousal in Alzheimer's Caregivers: A Preliminary Examination of the Temporal Relations Between Activity and Affect

The primary purpose of this study was to examine the synchronous and temporal relations between engagement in activities and the two primary dimensions of affect—namely, positive and negative affect—using an intensive time-series design called concomitant time series analysis (CTSA). Twenty-four dementia caregivers completed 56 diary measures (4 times per day for 2 weeks) assessing their experience of positive and negative affect as well as engagement in a variety of activities. Total number of activities was significantly correlated with positive affect (r = .40), but not negative affect (r = -.12). Obtained pleasure from activities was significantly correlated with both positive (r = .42) and negative affect (r = - .17). These results may help further develop behavioral models of depression by suggesting that behavioral or self-reinforcing activities are associated primarily (or more saliently) with one's experience of positive affect. Future research examining the effect of behavioral interventions on both positive and negative affect is suggested, as is the examination of factors that may be more strongly associated with negative affect.
