Luck and interests

Recent work on the nature of luck widely endorses the thesis that an event is good or bad luck for an individual only if it is significant for that individual. In this paper, I explore this thesis, showing that it raises questions about interests, well-being, and the philosophical uses of luck. In Sect. 1, I examine several accounts of significance, due to Pritchard (2005), Coffman (2007), and Rescher (1995). Then in Sect. 2 I consider what some theorists want to ‘do’ with luck, taking important examples from epistemology (explaining Gettier-style examples) and political philosophy (offering a rationale for the just distribution of resources in society), while suggesting implications for significance. Drawing together lessons from Sects. 1 and 2, I develop a new account of significance in Sect. 3 before concluding with reflections on the debate in Sect. 4.     

ECOBEHAVIORAL CHARACTERISTICS OF A PEDIATRIC BURN INJURY UNIT

Behavioral observations were conducted on 40 children admitted consecutively to an inpatient pediatric burn care unit (PBCU) over a 6-month period. Children's responses to the PBCU environment as well as adult responses to patients were assessed. Data indicated that children most frequently (a) were oriented and alert, (b) emitted vocalizations or verbalizations, (c) were environmentally engaged, (d) and demonstrated positive or neutral affective responding. Adult-child interactions occurred during the majority of observations. Age was found to be significantly related to the type of distress response exhibited. Positive responses indicative of patient well-being were found to be associated with environmental engagement and the presence of other patients. In general, little evidence emerged to support the notion of a PBCU response pattern which resembles that observed in pediatric intensive care units (i.e., ICU syndrome). The use of observational methods for studying the behavioral adaptation of children in medical settings and the implications of the data for the design of interventions on PBCUs are discussed.     

Developmental differences in visual processing: strategy versus structure

The present study was an examination of two contrasting explanations for the finding that young children tend to classify objects according to similarity relations whereas adults emphasize dimensional structure. Subjects from three different age groups were given tasks that tapped different aspects of the visual process: Feature search, Conjunction search, and Restricted Classification tasks. In addition, three different stimulus objects (a highly separable, a highly integral, and an intermediate dimensional combination) were studied to explore the contribution of stimulus structure in dictating the nature of the processing mode. The results provided evidence against the view that children perceive objects according to a more primitive holistic structure. Rather, the results can be taken with past research to suggest that less efficient visual processing may lead the younger subjects to adopt a classification strategy that emphasizes similarity relations. In addition, the current research supported Garner's (1974, The processing of information and structure, Potomac, MD: Erlbaum) suggestion that the nature of the processing mode is stimulus-driven.     

A CRT graphics system for experimental research

A graphics system to create, display, store, and print stimuli in a hardware-enhanced, microcomputer-driven CRT environment is described. This graphics system is compared with other computer-based systems, as well as with systems requiring the use of tachistoscopes.     

Child abuse: Prognostic factors in therapy effectiveness

We have attempted to define the problem of child abuse by separating the abusers into two categories. Pattern abusers seem to be primarily a social issue in that the abuse is an outgrowth of the parental charge to control her/his child. However, another abuser is seen as a borderline or psychotic individual when the abuse is an outgrowth of a transferential distortion on the part of the parent. It was suggested that family therapy for the latter may be the preferential mode of intervention.     

Pattern alternation: Effects of spatial frequency and orientation

Campbell and Howell (1972) reported an effect called “monocular pattern alternation.” They found that a pattern composed of two orthogonal sinusoidal gratings, one horizontal and the other vertical, underwent rivalry when viewed monocularly for a period of time. In the present study, it has been shown that monocular pattern alternation depends upon the orientation of the pattern and the spatial frequency of its components. Fewer reversals were found for an obliquely oriented pattern than for a pattern with components in the horizontal and vertical meridians. Alternation rate was higher when the gratings were similar in frequency but differed in orientation than when the components of the pattern differed in both dimensions. It was concluded that pattern alternation reflects an antagonistic interaction between interdependent channels in the human visual system that respond to orientation and spatial frequency.     

Family patterns leading to learning disability: A cognitive approach

Traditional treatment of the learning disabled child seeks to offer an individualized remediation. The authors offer as an alternative the innovative use of the family therapy modality for treatment of the learning dysfunction. This approaches the source of the learning dysfunction embedded in the faulty communication patterns within the family. The child has the opportunity to experience and more accurately comprehend the communication patterns, become more adept at interpretation of implicit meanings, and to transfer these developing skills to the formal learning situation.
