The fundamental question I consider is the following: What is it that makes one thing a person and another thing not? I do not provide a complete answer; rather I begin to develop a framework for answering the question. In this essay I do the following: (1) distinguish between the powers possessed by persons and the constitutions of persons, and propose some metaphysical conjectures concerning the relationship between persons' powers and their constitutions; (2) propose for Christians, as well as for others, an hylomorphic soul-body alternative to Cartesianism; (3) highlight some prominent differences between the nature of human persons to problems in biomedical ethics concerning the ontological and moral status of human embryos and of the comatose. 相似文献

Toward a theory of individual differences and leadership: understanding the motivation to lead. 总被引:1,自引:0,他引:1
A broad, integrative theoretical framework for understanding the relationship between individual differences and various leader behaviors is presented; it proposes a new individual-differences construct called the motivation to lead (MTL). A large-scale study using 3 samples in different occupational and cultural contexts shows 3 factors underlying MTL, namely, affective-identity, noncalculative, and social-normative MTL. A parsimonious model of antecedents to MTL is developed through hierarchical regression modeling and is cross-validated using confirmatory latent variable modeling. MTL is shown to provide incremental validity over other predictors such as general cognitive ability, values, personality, and attitudes in the prediction of 2 behavioral measures of leadership potential. Findings are discussed with reference to the theoretical framework proposed for understanding individual differences in leader behavior. 相似文献

Psychoanalysis and anesthesiology appear radically different in their clinical practice, yet they share a focus of inquiry: unconscious processes. Despite this common domain, there has been no exploration of the relationship between "the unconscious" as conceived by psychoanalysts and "surgical unconsciousness" as conceived by anesthesiologists. This is likely due to the fact that general anesthesia has been assumed to be a state in which the brain is simply "turned off." More recent neuroscientific data invalidate this assumption by demonstrating that the anesthetized brain is both cognitively dynamic and capable of implicit learning. Current perspectives on anesthetic mechanisms suggest that general anesthesia is characterized not simply by the absence of cognitive activity, but by the disintegration of cognitive activity. The cognitive unbinding paradigm of general anesthesia is discussed and its application to Wilfred Bion's theory of thinking, as well as his concept of attacks on linking, is elucidated. Based on the common structure and function of unconscious processes in psychoanalysis and anesthesiology, the foundation of a general theory is established. 相似文献

The purpose of the present research was to propose and test a motivational process model of academic achievement. The model
posits that parental, teachers, and school administration support for students' autonomy positively influences students' perceived
school competence and autonomy. In turn, perceived school competence and autonomy affect positively self-determined school
motivation which in turn influences academic achievement. Two studies using a prospective design tested the adequacy of the
model. In Study I, participants were 1,623 ninth-grade students. Results from structural equation modeling supported the motivational
model. Participants in Study 2 were 1,098 tenth-grade students. Results from this study corroborated those of Study 1 controlling
for students' prior achievement in the ninth grade. The role of self-determinod school motivation in academic achievement
is discussed and avenues for future research are considered.

This article meta-analytically summarizes the literature on training motivation, its antecedents, and its relationships with training outcomes such as declarative knowledge, skill acquisition, and transfer. Significant predictors of training motivation and outcomes included individual characteristics (e.g., locus of control, conscientiousness, anxiety, age, cognitive ability, self-efficacy, valence, job involvement) and situational characteristics (e.g., climate). Moreover, training motivation explained incremental variance in training outcomes beyond the effects of cognitive ability. Meta-analytic path analyses further showed that the effects of personality, climate, and age on training outcomes were only partially mediated by self-efficacy, valence, and job involvement. These findings are discussed in terms of their practical significance and their implications for an integrative theory of training motivation. 相似文献

Spatial scaling is an integral aspect of many spatial tasks that involve symbol-to-referent correspondences (e.g., map reading, drawing). In this study, we asked 3–6-year-olds and adults to locate objects in a two-dimensional spatial layout using information from a second spatial representation (map). We examined how scaling factor and reference features, such as the shape of the layout or the presence of landmarks, affect performance. Results showed that spatial scaling on this simple task undergoes considerable development, especially between 3 and 5 years of age. Furthermore, the youngest children showed large individual variability and profited from landmark information. Accuracy differed between scaled and un-scaled items, but not between items using different scaling factors (1:2 vs. 1:4), suggesting that participants encoded relative rather than absolute distances. 相似文献

Adhering to the view that emotional reactivity is organized in part by underlying motivational states--defensive and appetitive--we investigated sex differences in motivational activation. Men's and women's affective reactions were measured while participants viewed pictures with varied emotional and neutral content. As expected, highly arousing contents of threat, mutilation, and erotica prompted the largest affective reactions in both men and women. Nonetheless, women showed a broad disposition to respond with greater defensive reactivity to aversive pictures, regardless of specific content, whereas increased appetitive activation was apparent for men only when viewing erotica. Biological and sociocultural factors in shaping sex differences in emotional reactivity are considered as possible mediators of sex differences in emotional response. 相似文献

This paper considers the relation between the development of spatial cognition and children’s use of maps and models. A new theoretical perspective is presented that takes into account the influences of maps on the development of spatial cognition. Maps provide a perspective on spatial information that differs in important ways from the perspective gained from direct experience navigating in the world. Using and thinking about maps may help children to acquire abstract concepts of space and the ability to think systematically about spatial relations that they have not experienced directly. In addition, exposure to maps may help children to think about multiple spatial relations among multiple locations. The results of previous studies that have demonstrated developmental differences in children’s cognition of large‐scale environments are examined from this theoretical perspective. This review suggests that the development of spatial cognition consists partly of the acquisition of models of large‐scale space, and that maps influence the development of the modern Western model. 相似文献

The purpose of this paper is to present a preliminary framework for conceptualizing the caregiving behavioral system. Following Bowlby (1982), we propose that caregiving is organized within a goal-corrected behavioral system that is reciprocal to attachment. The set-goal of the system is to keep dependent offspring close or safe; its adaptive function is protection of the young. The caregiving system is designed to provide changing levels and forms of protection depending upon the developmental and individual requirements of the young. However, the evolutionary interests of the parent are not entirely overlapping with that of the child because the parent's evolutionary fitness depends on the fitness of all her offspring. Caregiving is one of several motivational systems in the parent. Depending upon circumstances, parents may select from a range of caregiving strategies, which are believed to correspond to the continuum of child attachment relationships (secure, avoidant, ambivalent). The adult caregiving system is believed to be guided by an internal representation or mental model of caregiving. This system has its roots in early attachment—caregiver experiences, but is distinct from them. We suggest that the caregiving representational system becomes consolidated initially in adolescence and undergoes change during the transition to parenthood and as a function of interaction with the child. Once this development is complete, situations of danger and safety should activate the caregiving behavioral system. Under normal circumstances, if the parent's own attachment system is aroused she would appeal to her own attachment figures rather than to the child. However, situations that engender feelings of helplessness in the mother (i.e., which cause her to perceive herself as unable to protect the child) may disorganize or disable the caregiving system on both the behavioral and representational levels. 相似文献
