Another look at women in the united states army: A comment on woelfel's article

Woelfel's (1981) article on women in the United States Army is examined from a situation-centered perspective. The assumption implied by military authors that women are liabilities to be accommodated to the existing military structure is challenged, and an alternative view of women as potential contributors to the evolution of androgynous standards of leadership is offered.     

The onset of receding motion captures attention: comment on Franconeri and Simons (2003)

Franconeri & Simons (2003) reported that some but not all types of motion capture attention in a visual search task, ostensibly because some types of motion are behaviorally significant. In the present article, we argue that a more parsimonious explanation of their results is that the onset of motion, but not motion per se, captures attention. This conclusion helps to resolve inconsistencies between the Franconeri and Simons findings and earlier reports from other investigators and is consistent with results that we have recently reported (Abrams & Christ, 2003). The Franconeri and Simons interpretation rests largely on their failure to find attentional capture by one type of motion-simulated receding motion. We report here the results of two experiments that demonstrate that the onset of receding motion does indeed capture attention when the motion is produced using stereo depth cues. As we have argued elsewhere, the capture of attention in displays containing motion appears to be dependent on the onset of the motion, rather than on the mere presence of specific types of motion as suggested by Franconeri and Simons. One possible explanation is that the onset of motion captures attention because it serves as a strong cue to animacy--and the detection of nearby animals can have important consequences for survival.     

Spatial frequencies as a medium for guiding attention: comment on Lamb, Yund, and Pond (1999)

M. R. Lamb, E. W. Yund, and H. M. Pond (1999) question L. C. Robertson's (1996) earlier arguments that attention can be guided by spatial frequencies when searching for a target in complex visual patterns. The 2 major findings they report to argue against Robertson's conclusions are discussed and found inadequate for the purposes of abandoning this hypothesis. Instead, findings reported in the accompanying article in combination with previous findings reported by 2 of the same authors (M. R. Lamb & E. W. Yund, 1996) provide converging evidence to support spatial frequency as a medium for guiding attention.     

Selective attention and distractor frequency in naming performance: comment on Dhooge and Hartsuiker (2010)

E. Dhooge and R. J. Hartsuiker (2010) reported experiments showing that picture naming takes longer with low- than high-frequency distractor words, replicating M. Miozzo and A. Caramazza (2003). In addition, they showed that this distractor-frequency effect disappears when distractors are masked or preexposed. These findings were taken to refute models like WEAVER++ (A. Roelofs, 2003) in which words are selected by competition. However, Dhooge and Hartsuiker do not take into account that according to this model, picture-word interference taps not only into word production but also into attentional processes. Here, the authors indicate that WEAVER++ contains an attentional mechanism that accounts for the distractor-frequency effect (A. Roelofs, 2005). Moreover, the authors demonstrate that the model accounts for the influence of masking and preexposure, and does so in a simpler way than the response exclusion through self-monitoring account advanced by Dhooge and Hartsuiker.     

Meditation and the startle response: a case study

The effects of two kinds of meditation (open presence and focused) on the facial and physiological aspects of the defensive response to an aversive startle stimulus were studied in a Buddhist monk with approximately 40 years of meditation experience. The participant was exposed to a 115-db, 100-ms acoustic startle stimulus under the 2 meditation conditions, a distraction condition (to control for cognitive and attentional load) and an unanticipated condition (startle presented without warning or instruction). A completely counterbalanced 24-trial, single-subject design was used, with each condition repeated 6 times. Most aspects of the participant's responses in the unanticipated condition did not differ from those of a comparison group of 12 age-matched male controls. Both kinds of meditation produced physiological and facial responses to the startle that were smaller than in the distraction condition. Within meditation conditions, open presence meditation produced smaller physiological and facial responses than focused meditation. These results from a single highly expert meditator indicate that these 2 kinds of meditation can differentially alter the magnitude of a primitive defensive response.     

Wisdom as a Meditation on Life: Spinoza on Bacon and Civil History

In letter 37 to Johannes Bouwmeester, Spinoza identifies a historiola mentis à la Bacon as an important tool for distinguishing more easily between adequate and inadequate ideas. This paper contends that Spinoza's advice is to take into account Baconian-style ‘Civil History’ as providing instructive material for contemplating the variety, complexity, and persistency of human passionate behaviour. Specifically, it argues that Baconian civil history forms an integral part of Spinoza's reflections on provisional morality. Although for Spinoza, philosophical beatitude ultimately demands understanding affects through their first causes – the intuitive perception of things sub specie aeternitatis – in the realm of everyday Spinoza allows for a different, more pragmatic approach to morality. This paper argues at this stage that a philosophical understanding of the mind and its affections is not needed. Spinoza, following Bacon, holds that conduct of practical affairs is particularly improved when those so engaged acquire historical knowledge of the human condition and apply it. Specifically, both authors place special emphasis on a history of men's characters, actions, and vices as providing the material basis for concrete, directly applicable moral and civil precepts.     

Occlusion, symmetry, and object-based attention: comment on Behrmann, Zemel, and Mozer (1998)

The validity of M. Behrmann, R. Zemel, and M. Mozer's (1998) finding that object-based attention can be directed toward occluded objects is examined in 3 experiments. In M. Behrmann et al.'s (1998) original study, participants made speeded judgments of whether the numbers of bumps attached to 2 arms of an X shape were the same or different. The 2 sets of bumps belonged either to a single object, 2 different objects, or 2 separated parts of an occluded object. Unfortunately, this objecthood manipulation was confounded by the symmetry of the stimuli. Experiment 1 replicated M. Behrmann et al.'s main results using identical stimuli. Experiments 2a and 2b dissociated objecthood from symmetry. The results suggest that the effects of object-based attention found by M. Behrmann et al. are largely due to symmetry. The stimuli used in M. Behrmann et al. are not appropriate for examining the relation between object-based attention and occlusion.     

Object-based control of attention is sensitive to recent experience

How is attention guided by past experience? In visual search, numerous studies have shown that recent trials influence responses to the current trial. Repeating features such as color, shape, or location of a target facilitates performance. Here we examine whether recent experience also modulates a more abstract dimension of attentional control, object-based and location-based control. Participants performed a cued target discrimination task with stimuli presented on 2 rectangles. Response times to targets appearing in an uncued location on a cued rectangle were faster than to targets on the uncued rectangle, demonstrating an object-based attentional benefit. We investigated the object-based benefit on the current trial contingent on the cue-target relationship on the previous trial. The object-based benefit was significant only when the cued object contained the target on the previous trial, not when the uncued object contained the target. This effect of recent experience was not due to either the repetition of spatial cue-target location or the repetition of the response, but to adaptation to contingencies in the environment. Our results suggest a unifying view of attentional control that spans the concrete dimensions of control (e.g., determining the relative importance of red vs. blue) to the abstract (determining the relative importance of objects vs. locations in space). Attention closely tracks the short time scale structure of the environment and automatically adapts to optimize performance to this structure.

Selective attention and attention switching: towards a unified developmental approach

We review and relate two literatures on the development of attention in children: one concerning flexible attention switching and the other concerning selective attention. The first is a growing literature on preschool children’s performances in an attention‐switching task indicating that children become more flexible in their attentional control during the preschool years. The second literature encompasses a large and robust set of phenomena for the same developmental period that indicates a protracted course of development for selective attention in children. We ask whether developmental changes in processes of selective attention may contribute to more flexible attention switching. We consider the two sets of phenomena with respect to this question and propose an empirical agenda for their joint study that may lead ultimately to a unified account of the development of selective attention and attention switching.
