Perception without attention: results of a new method.

Having found by the use of a new method for examining perception without attention that grouping and texture segregation do not seem to occur (see Mack, Tang, Tuma, Kahn, & Rock (1992) Cognitive Psychology, 24, we go on to ask what is perceived without attention using this new method. Our subjects receive only one inattention trial in a sequence of trials involving a visual distraction task. In addition to the distraction task in the inattention trial, subjects received a stimulus of which they had no prior knowledge or expectation and were questioned or tested directly afterward for their perception of that stimulus. Two subsequent trials containing test stimuli serve as within-subject controls. The results of a series of experiments indicate that the presence of one or more stimulus objects and their locations are preattentively perceived, as is their color, but shape is not. Because individual items are detected without attention, we conclude that perceptual organization is initially based on a principle in which connected regions of uniform stimulation are inferred to be discrete units (the principle of uniform connectedness). One striking, unexpected finding is that without attention many subjects have no awareness at all of the stimulus object, an effect we call inattentional blindness.     

Immediate correction and adaptation based on viewing a prismatically displaced scene

It was shown that when observers view a scene of a room through displacing prisms there is an immediate correction of the prismatic distortion. Objects appear to lie in a direction closer to their true direction than to that produced by the refraction of the prisms. It was also shown that a brief period of exposure to the prismatically viewed scene, without movement or sight of the body, results in substantial adaptation to the displacement.     

The Stress of Organisational Change: A Dynamic Process Model

Plongées dans un marché mondial, les organisations ne cessent de subir de profonds changements. Encore que la plupart de ces changements soient nécessaires et souvent retardés, ils présentent comme inconvénient le risque de coûts élevés en terme d'accroissement des dépenses de santé, de pertes de productivité, de baisse de la satisfaction professionnelle et de chute du moral. Ces coûts peuvent être directement imputés à la détresse qui frappe les salariés d'une organisation confrontée à des changement permanents. Cet article propose un modèle dynamique permettant d'aborder les articulations complexes entre le changement organisationnel et le stress subi par les individus. A partir de ce modèle, des interventions prenant en compte tous les aspects du problème pourront être conçues pour aider les salariés à gérer le stress provoqué par les mutations des organisations.
Organisations in the global marketplace continue to experience tremendous change. Although most of these changes are necessary and long overdue, the downside includes the risk of huge costs in terms of increased health care expenses, lost productivity, lower levels of job satisfaction, and low morale. These costs may be directly attributed to the distress that is created when an organisation's employees encounter constant changes. This paper establishes a dynamic framework from which we can begin to understand the complex interplay between change at the organisational level and stress at the individual level. Using this framework, comprehensive interventions can ultimately be developed to help employees manage the stress of organisational transitions.     

Conceptual deficits and aging: the Category Test

Category Test performance of 41 bright aged normals was compared with the performance of 40 young normals and a group of 43 patients with suspected neurological dysfunction. The aged normals were not only as deficient as the neurologic patients but showed a similar pattern of deficits on Category subtests. The extreme difficulty experienced by aged normals and patients on Subtests III and IV was explained as a function of task complexity rather than of conceptual difficulty of conceptual principles and task complexity in a variety of impaired groups was suggested.     

Perceived movement of the afterimage during eye movements

The question of whether an afterimage viewed in a dark field appears to move during eye movement was studied by comparing recordings of eye movements with recordings of reports of perceived movement. The correlation was found to be quite good even under conditions where the eye movements were spontaneous rather than specifically directed. The results were taken to support the hypothesis that the behavior of the retinal image is “interpreted” by taking into account information concerning what the eyes are doing.     

Carkhuff's Human Technology: A Verification and Extension of Kelly's (1997) Suggestion to Integrate the Humanistic and Technical Components of Counseling

In the May/June 1997 issue of the Journal of Counseling & Development, Eugene Kelly contended that the counseling profession should integrate its theories to combine the strengths of both the humanistic and the technical orientations in the field. Kelly's recommendation is supported by previous efforts that have already advanced the field. Human Technology (HT) as devised by Robert Carkhuff integrated nondirective, psychodynamic, and behavioristic counseling modes. Extensions of HT also demonstrate the continuing growth potential in the integrative strategy. In this article, the authors discuss those endeavors to emphasize the potential contributions to be attained by integrating humanistic and technical orientations.     

Inattentional blindness: looking without seeing

Surprising as it may seem, research shows that we rarely see what we are looking at unless our attention is directed to it. This phenomenon can have serious life-and-death consequences. Although the inextricable link between perceiving and attending was noted long ago by Aristotle, this phenomenon, now called inattentional blindness (IB), only recently has been named and carefully studied. Among the many questions that have been raised about IB are questions about the fate of the clearly visible, yet unseen stimuli, whether any stimuli reliably capture attention, and, if so, what they have in common. Finally, is IB an instance of rapid forgetting, or is it a failure to perceive?
