Attentional capture in serial audiovisual search tasks

The phenomenon of attentional capture has typically been studied in spatial search tasks. Dalton and Lavie recently demonstrated that auditory attention can also be captured by a singleton item in a rapidly presented tone sequence. In the experiments reported here, we investigated whether these findings extend cross-modally to sequential search tasks using audiovisual stimuli. Participants searched a stream of centrally presented audiovisual stimuli for targets defined on a particular dimension (e.g., duration) in a particular modality. Task performance was compared in the presence versus absence of a unique singleton distractor. Irrelevant auditory singletons captured attention during visual search tasks, leading to interference when they coincided with distractors but to facilitation when they coincided with targets. These results demonstrate attentional capture by auditory singletons during nonspatial visual search.     

Well-Being and Pluralism

It is a commonly expressed sentiment that the science and philosophy of well-being would do well to learn from each other. Typically such calls identify mistakes and bad practices on both sides that would be remedied if scientists picked the right bit of philosophy and philosophers picked the right bit of science. We argue that the differences between philosophers and scientists thinking about well-being are more difficult to reconcile than such calls suggest, and that pluralism is central to this task. Pluralism is a stance that explicitly drives towards accommodating and nurturing the richness and diversity of well-being, both as a concept and as an object of inquiry. We show that well-being science manifests a contingent pluralism at the level of methodology, whereas philosophy of well-being has largely rejected pluralism at the conceptual level. Recently, things have begun to change. Within philosophy, conceptual monism is under attack. But so is methodological pluralism within science. We welcome the first development, and bemoan the second. We argue that a joined-up philosophy and science of well-being should recognise the virtues of both conceptual and methodological pluralism. Philosophers should embrace the methodological justification of pluralism that can be found in the well-being sciences, and scientists should embrace the conceptual reasons to be pluralist that can be found in philosophical debate.

     

Families created through surrogacy: mother-child relationships and children's psychological adjustment at age 7

Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 surrogacy, 32 egg donation, and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity, or child adjustment, although the surrogacy and egg donation families showed less positive mother-child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years.     

Informational determinants of females' self-attributions and observers' judgments of them in an achievement situation.

A female (A) received feedback about both her own and a male or female other's (B's) performance on an achievement task, and then estimated the likelihood that she and B possessed each of several attributes related to competence, likeableness, and physical attractiveness. The situation was witnessed by a male or female observer who then judged B's attributes and predicted A's and B's ratings of one another. A formulation of social inference processes developed by Gollob was used to identify and compare the informational cues used by actors and observers in making these attributions. The contributions of these cues depended substantially on the type of attribute being inferred, the judge (A or the observer), and whether the judgment was made of A or of B. A's behavior (i.e., her performance on the achievement task) contributed less to her self-attributions than it did either to her predictions of how B would rate her or to observers' actual judgments of her attributes. A's self-attributions tended to be relatively more influenced by her experiences before participating in the experiment. Whereas A appeared to use B's performance as a comparative standard when judging her own competence and expected B to do likewise, observers did not use B's performance in this manner when judging A. Moreover, A did not use her own performance as a standard when judging attributes of B. The article discusses theoretical implications of these results for attribution and self-perception processes.     

Effects of naloxone on acquisition and extinction of jump-up avoidance behavior in rats

Two experiments were carried out to assess the effects of the opioid antagonist, naloxone, on the acquisition and extinction of shock avoidance by rats in the jump-up apparatus. In Experiment 1 naloxone pretreatment facilitated acquisition but had no effect on extinction of avoidance behavior. In the second experiment the effect of naloxone on acquisition was replicated and in addition, it was shown that naloxone enhanced freezing when a response prevention or flooding procedure was introduced. Again naloxone failed to alter the course of extinction, nor did it interact with the effects of flooding which, by itself, facilitated extinction. The results suggest that naloxone's effects are limited to increasing the functional intensity of the US, and provide further support for the dissociation between extinction of avoidance behavior and other indices of fear.     

Conditional handedness: Handedness changes in multiple personality disordered subject reflect shift in hemispheric dominance

This study investigates whether the host personality (Pe) and the primary alterpersonality (Pa) of a woman with multiple personality disorder are controlled by the left and right hemispheres, respectively. Results support the hypothesis. Behavioral and preference measures indicate that Pe is strongly right handed and Pa is left handed. Verbal and musical dichotic tests show significantly greater accuracy for stimuli presented to the left ear for Pa and to the right ear for Pe. It is concluded that shifts in hemisphericity involve redistribution of attentional resources and callosal suppression. “Conditional handedness” is proposed as a handedness subtype, characterizing persons who alternate personalities and consistently display alternate hand preferences linked to specific personality characteristics.     

promoting employability in a “flat” world

T. L. Friedman (2005) described a “flat” world platform where competition and collaboration take place in real time among people all over the planet. Implications exist for people to assume responsibility for managing their own careers and ensuring their own security in a global economy. This article addresses those challenges from both the individual's and the career counselor's perspectives. It proposes the “intelligent career” framework—comprising 3 “ways of knowing” and interdependencies among them—as a helpful basis for effective career development. People can use the framework to navigate their careers in order to develop new skills, develop broader reputations, and in turn sustain employability.     

Psynteract: A flexible,cross-platform,open framework for interactive experiments

We introduce a novel platform for interactive studies, that is, any form of study in which participants’ experiences depend not only on their own responses, but also on those of other participants who complete the same study in parallel, for example a prisoner’s dilemma or an ultimatum game. The software thus especially serves the rapidly growing field of strategic interaction research within psychology and behavioral economics. In contrast to all available software packages, our platform does not handle stimulus display and response collection itself. Instead, we provide a mechanism to extend existing experimental software to incorporate interactive functionality. This approach allows us to draw upon the capabilities already available, such as accuracy of temporal measurement, integration with auxiliary hardware such as eye-trackers or (neuro-)physiological apparatus, and recent advances in experimental software, for example capturing response dynamics through mouse-tracking. Through integration with OpenSesame, an open-source graphical experiment builder, studies can be assembled via a drag-and-drop interface requiring little or no further programming skills. In addition, by using the same communication mechanism across software packages, we also enable interoperability between systems. Our source code, which provides support for all major operating systems and several popular experimental packages, can be freely used and distributed under an open source license. The communication protocols underlying its functionality are also well documented and easily adapted to further platforms. Code and documentation are available at https://github.com/psynteract/.     

Truth and consequences

In his 1987 paper “Truth or Consequences,” Dan Brock describes a deep conflict between the goals and virtues of philosophical scholarship and public policymaking: whereas the former is concerned with the search for truth, the latter must primarily be concerned with promoting good consequences. When philosophers are engaged in policymaking, he argues, they must shift their primary goal from truth to consequences—but this has both moral and methodological costs. Brock’s argument exemplifies a pessimistic, but not uncommon, view of the possible shape and nature of applied philosophy. The present paper paints a richer and more optimistic picture. It argues that the difference between theoretical philosophy and applied philosophy is not best understood as a choice between truth and consequences. On the contrary, applied philosophers engage in forms of truth-seeking that are properly concerned with consequences—including the consequences of philosophical practice itself.
