Life and teleology

A comprehensive definition of the phenomenon called life led to the addition of many dimensions to the natural sciences, and especially the conscious mental dimension. Historical attention is paid not only to those employing the natural philosophical paradigms, but also to evolutionary theories and to the Kantian teleological philosophy. The belief that science can solve the riddle of life is a category of purposal thinking. A revised version of critical teleology is essential for comprehension of life.     

PREVENTING SCHOOL VANDALISM AND IMPROVING DISCIPLINE: A THREE-YEAR STUDY

Vandalism is a major problem facing educators and taxpayers alike. The present investigation analyzed how vandalism costs and student disruption were related to the implementation of a training and consultation package designed to increase the reinforcing ambience of the school. A positive environment, it was posited, would displace previous events that may have set the occasion for vandalism, with cues to promote productive school performance. Eighteen elementary and junior high schools were involved over a 3-year period. Using a delayed treatment control design, treatment was delivered following either 4 or 13 months of baseline. During treatment, teams of school personnel attended training workshops in behavioral strategies for reducing vandalism and disruption by students in school. Each team also met regularly on its campus to plan and implement programs on a schoolwide basis. To demonstrate that reinforcing procedures were actually implemented and accompanied by change in student performance, these variables were periodically probed throughout the study. Project staff also provided consultation. Vandalism costs decreased significantly (p < .05) more in treatment than control schools, with an average reduction of 78.5% for all project schools. Rates of praise delivered by project teachers and other randomly selected teachers in the school increased significantly (p < .05), and rates of off-task behavior by students decreased significantly (p < .05) following treatment. The staff development model used in this study appeared to be both feasible and economical.     

Principles and Problems in the Assessment of Quality of Life in Health Care

A remarkable surge in efforts to assess the quality of life of patients has occurred in recent years in medical research. Philosophical discussions of these developments have focused, on the one hand, on epistemological reservations about the plausibility of measuring quality of life and, on the other hand, on moral and ethical qualms about the meaning of life conveyed in such assessments. Whilst providing an important note of caution, such critiques fail to recognise two basic principles of quality of life in medical research. Firstly it is intended to provide understanding about groups and categories of patients rather than individuals. Secondly the purpose of such research is to produce generalisations about the relative costs and benefits of specific health care interventions rather than absolute judgements regarding the quality of life of patients per se. Selecting a good quality of life measure for a clinical trial requires balancing criteria such as validity with practical feasibility. Such measures will play an increasingly central role in providing research evidence to improve health care.     

SELF-MAINTENANCE AS A RELIGIOUS CONCERN

Abstract. Human concern with problems of being and becoming promotes conceptions of ideal states of being, exemplified by paragons and heroes and projected as Utopias or visions of salvation; it leads to regimens for cultivating and maintaining individual ability to meet social expectations; and it produces fantasies, as in myth and popular literature, that rehearse the problems and that offer escape from them and roles to emulate in dealing with them. Many of these regimens and fantasies appear in the rituals and teachings of organized religion. Many also figure in private devotions apart from established religions. The many forms they take constitute much of the religious life of ordinary people. From this viewpoint, there is much to examine in American life.     

Aiming at Happiness: How Motivation Affects Attention to and Memory for Emotional Images

Socioemotional Selectivity Theory (Carstensen, L. L., Isaacowitz, D. M., & Charles, S. T. (1999). American Psychologist, 54, 155–181) posits that older adults, and anyone else who perceives their time as limited, show a motivational shift toward emotion regulation which causes them to exhibit a positivity bias and negativity avoidance in attention and memory. We tested whether such a motivational shift can indeed cause changes in emotional processing by manipulating motivation in a sample of young adults. After the manipulation, participants looked at real-world images while their eye movements were tracked. It was found that participants motivated to regulate emotion attended less to negative than positive images and showed less looking time to all stimulus types compared to the other two conditions. No evidence was found linking the motivational manipulation to emotional memory.

Children's suggestibility for an instance of a repeated event versus a unique event: the effect of degree of association between variable details

Are children who experience an event repeatedly more suggestible about an instance of the event than children who experience it once? Researchers have answered this question both in the affirmative and in the negative. In this study, we hypothesized that the degree of association between details that changed across instantiations of the event would help to explain the discrepancy. Preschoolers (4- and 5-year-olds) and first graders (6- and 7-year-olds) participated in either a single play session or four repeated play sessions, each of which contained 16 critical details. Across play sessions in the repeat-event condition, half of the critical details were associated and half were not associated. During a biasing interview 2 weeks later, children were misinformed about half of the critical details. The next day, children answered free and cued recall questions about the target play session. Among older children, repeat-event participants were more suggestible than single-event participants, especially for high-association details. Among younger children, repeat-event participants were more suggestible than single-event participants for low-association details. Consistent with some current theories of children's memory, older children were more suggestible than younger children.     

The influence of the immediate visual context on incremental thematic role-assignment: evidence from eye-movements in depicted events

Studies monitoring eye-movements in scenes containing entities have provided robust evidence for incremental reference resolution processes. This paper addresses the less studied question of whether depicted event scenes can affect processes of incremental thematic role-assignment. In Experiments 1 and 2, participants inspected agent-action-patient events while listening to German verb-second sentences with initial structural and role ambiguity. The experiments investigated the time course with which listeners could resolve this ambiguity by relating the verb to the depicted events. Such verb-mediated visual event information allowed early disambiguation on-line, as evidenced by anticipatory eye-movements to the appropriate agent/patient role filler. We replicated this finding while investigating the effects of intonation. Experiment 3 demonstrated that when the verb was sentence-final and thus did not establish early reference to the depicted events, linguistic cues alone enabled disambiguation before people encountered the verb. Our results reveal the on-line influence of depicted events on incremental thematic role-assignment and disambiguation of local structural and role ambiguity. In consequence, our findings require a notion of reference that includes actions and events in addition to entities (e.g. Semantics and Cognition, 1983), and argue for a theory of on-line sentence comprehension that exploits a rich inventory of semantic categories.     

When the ordinary seems unexpected: evidence for incremental physical knowledge in young infants

According to a recent account of infants' acquisition of their physical knowledge, the incremental-knowledge account, infants form distinct event categories, such as occlusion, containment, support, and collision events. In each category, infants identify one or more vectors which correspond to distinct problems that must be solved. For each vector, infants acquire a sequence of variables that enables them to predict outcomes within the vector more and more accurately over time. This account predicts that infants who have acquired only a few of the variables in a sequence should err in two ways in violation-of-expectation tasks: (1) they should view impossible events consistent with their incomplete knowledge as expected (errors of omission), and (2) they should view possible events inconsistent with their incomplete knowledge as unexpected (errors of commission). Many reports have shown that infants who have not yet identified a variable in an event category produce errors of omission: they fail to view impossible events involving the variable as unexpected. However, there has been no report revealing errors of commission in infants' responses to possible events. The present research examined whether 3- and 2.5-month-old infants, whose knowledge of occlusion events is very limited, would produce errors of commission as well as errors of omission when responding to these events. At 3 months of age, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its upper edge. At 2.5 months, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its lower edge. These findings provide a new kind of evidence for the incremental-knowledge account, and more generally for the notion that infants, like older children and adults, engage in rule-based reasoning about physical events.
