The automatic orienting of attention to goal-relevant stimuli

It is often assumed that attention is automatically allocated to stimuli relevant to one’s actual goals. However, the existing evidence for this idea is limited in several ways. We investigated whether words relevant to a person’s current goal influence the orienting of attention even when an intention to attend to the goal-relevant stimuli is not present. In two experiments, participants performed a modified spatial cueing paradigm combined with a second task that induced a goal. The results of the experiments showed that the induced goal led to the orientation of attention to goal-relevant words in the spatial cueing task. This effect was not found for words semantically related to the goal-relevant words. The results provide evidence for motivational accounts of attention, which state that the automatic allocation of attention is guided by the current goals of a person.     

Domestic violence against women: Understanding social processes and women's experiences

The prevalence of domestic abuse against women has been estimated as high as one in four. The risk is particularly high for women who are younger, economically dependent, unemployed and with children. Research about the factors that maintain situations of abuse has generally focused separately on the coping strategies of women, barriers to leaving the relationship and the perpetrators' means of abuse. In this study we used a community psychology perspective to seek a broader understanding of what maintains situations of abuse, in order to suggest interventions in a rural County in the North of England. Twelve women who had experienced domestic abuse and had used voluntary sector services agreed to be interviewed about their experiences and the resources and strategies available to them. Using grounded theory we generated four themes: (1) Commonalities and contradictions in the experience of abuse; (2) living with abuse; (3) the response of systems reinforced or challenged the abuse and (4) dealing with abuse beyond the relationship. These findings illustrate how situations of domestic abuse can be prolonged by limited options available to victims for support and protection, and a lack of active public acknowledgement that domestic abuse is unacceptable.

Perceptual simulation in developing language comprehension

We tested an embodied account of language proposing that comprehenders create perceptual simulations of the events they hear and read about. In Experiment 1, children (ages 7–13 years) performed a picture verification task. Each picture was preceded by a prerecorded spoken sentence describing an entity whose shape or orientation matched or mismatched the depicted object. Responses were faster for matching pictures, suggesting that participants had formed perceptual-like situation models of the sentences. The advantage for matching pictures did not increase with age. Experiment 2 extended these findings to the domain of written language. Participants (ages 7–10 years) of high and low word reading ability verified pictures after reading sentences aloud. The results suggest that even when reading is effortful, children construct a perceptual simulation of the described events. We propose that perceptual simulation plays a more central role in developing language comprehension than was previously thought.     

Libertarianism vs. Marxism: Reflections on G. A. Cohen‘s Self-Ownership, Freedom and Equality

Self-Ownership, Freedom and Equality is G.A. Cohens attempt to rescue something of the socialist outlook on society from the challenge of libertarianism, which Cohen identifies with the work of Robert Nozick in his famous book, Anarchy, State, and Utopia. Sympathizing with the leading idea that a person must belong to himself, and thus be unavailable for forced redistribution of his efforts, Cohen is at pains to reconcile the two. This cannot be done – they are flatly contrary. Moreover, equality is a nonsense principle, calling for such things as equal distribution of natural resources. But resources, as goods, are not natural: all require work to utilize. The only thing exchanged on markets is services, and estimates of value received are relevantly made only by those party to the exchanges in question. Imposition from above on voluntary exchange can only be socially counterproductive.     

Absolute localization of vibrotactile stimuli on the torso

Vibrotactile mobility systems present spatial information such as the direction of a waypoint through a localized vibration on the torso. Using these systems requires the ability to determine the absolute location of the stimulus. Because data are available only on the ability to determine the relative location of stimuli on the torso, we developed a novel method for measuring absolute localization on the basis of triangulation. For 15 observers, we calculated the subjective location of visual and tactile stimuli on the frontal half of the torso. The size of the 95% confidence intervals around the subjective tactile locations is about the size of the stimuli (1.66 cm) and is slightly larger than that around the subjective visual locations (mean difference, 0.17 cm). The error in tactile judgments over and above that in the visual judgments is present only for locations near the body midline. When the subjective visual and tactile locations are not co-located, the difference can best be described by a shift along the radius from the body midaxis. The same holds for the differences between the veridical and the subjective locations. Therefore, the difference between the veridical and the subjective directions of a stimulus is small. The results make us believe that stimulus locations on the torso are coded in polar coordinates of which the angle is perceptual invariant and the distance is less important, probably because it varies with changes in, among other things, posture and breathing.     

Empathy or Intersubjectivity? Understanding the Origins of Morality in Young Children’

This article is about young children’s morality and their concern for others’ wellbeing. Questions of what the value of others’ wellbeing can signify, how this value becomes visible to children and how it is expressed in their interaction will be posed. In this analysis, children’s commitment to others’ wellbeing is discussed in terms of two theories, namely the philosopher Maurice Merleau-Ponty’s (1962, 1964) theory of intersubjectivity and the psychologist Martin Hoffman’s (1984, 1987, 2000) theory of empathy. The interaction between children and adults in pre-school, drawn from different studies of morality (Johansson, 1999, 2001, 2002, 2003), constitutes the empirical basis. In the discussion, it is claimed that children’s care for others’ wellbeing can be understood in a fruitful way as experiences of, approaches to and ways of being involved in the other’s life-world rather than as expressions of empathy.

Execution architectures for program algebra

We investigate the notion of an execution architecture in the setting of the program algebra PGA, and distinguish two sorts of these: analytic architectures, designed for the purpose of explanation and provided with a process-algebraic, compositional semantics, and synthetic architectures, focusing on how a program may be a physical part of an execution architecture. Then we discuss in detail the Turing machine, a well-known example of an analytic architecture. The logical core of the halting problem—the inability to forecast termination behavior of programs—leads us to a few approaches and examples on related issues: forecasters and rational agents. In particular, we consider architectures suitable to run a Newcomb Paradox system and the Prisoner's Dilemma.

Associations Between Clinic-Referred Boys and Their Fathers on Childhood Inattention-Overactivity and Aggression Dimensions

The question asked in this study of 70 clinically referred 6- to 12-year-old boys with behavior problems was whether or not childhood inattention-overactivity and aggression are transmitted specifically from biological fathers to sons. Fathers' self-reported childhood inattention-overactivity on a retrospectively valid measure was exclusively associated with parents' ratings of their sons' current attention problems on the Mothers' Operational Measure for Sub-grouping (MOMS), the Revised Child Behavior Checklist (RCBCL), and an approximated DSM-IV inattention dimension. Fathers' self-reported childhood aggression was not associated with ratings of their sons' aggression on the MOMS or DADS (a parallel instrument for fathers), nor on DSM-III oppositional or conduct disorder dimensions, but it was exclusively associated with RCBCL ratings of sons' aggressive and delinquent behavior. None of the nonspecific correlations (father inattention-overactivity with son aggression or father aggression with son inattention-overactivity) was significant.
