The study examined viewing behaviour and learning outcome during multimedia learning in order to explore split‐attention processes in modality and spatial contiguity effects. Fourty students viewed a computer instruction depicting the process of lightning. Exploratory text was spoken, written near or written far from accompanying animations. Students who received spoken text outperformed students who received written text in recalling the major steps (retention) and in identifying correct solutions to problems (transfer), replicating a modality effect. Differences between near and far written text presentation in retention (d = 0.51) and transfer (d = 0.68) tests failed statistical significance. Two major characteristics concerning the learners' viewing behaviour were identified: (a) in written text presentation, learning was largely text directed and (b) learning success was related to the time learners' spent looking at animations, indicating that the processing of animations is a crucial factor in explanations of modality and spatial contiguity effects.

How can one discover the ethical issues associated with nanotechnologies? One heuristic is to tend closely to the ethical reflections of lay publics and the ways in which these are informed by experience with technological innovation, technology governance, and the (broken) promises of visionary science and technology. A close collaboration between social scientists and philosophers took this heuristic to its limits: On the one hand, it achieved remarkably fine–grained insights into public reflection about nanotechnologies. On the other hand, a philosophical analysis of these reflections makes apparent that there is a profound disconnect between the lay ethics rooted in public talk and the ethical and normative commitments that are embedded in nanotechnological research programs and practices. Accordingly, critical engagement with the ways in which ordinary people try to make sense of nanotechnologies constitutes a novel heuristic for the discovery of ethical issues. This introduction and the subsequent four papers show this heuristic at work.  相似文献

This article distinguishes among and examines three different kinds of argument for the thesis that moral responsibility and free action are each incompatible with the truth of determinism: straight manipulation arguments; manipulation arguments to the best explanation; and original-design arguments. Structural and methodological matters are the primary focus.  相似文献

Motor programming at the self-select paradigm was adopted in 2 experiments to examine the processing demands of independent processes. One process (INT) is responsible for organizing the internal features of the individual elements in a movement (e.g., response duration). The 2nd process (SEQ) is responsible for placing the elements into the proper serial order before execution. Participants in Experiment 1 performed tasks involving 1 key press or sequences of 4 key presses of the same duration. Implementing INT and SEQ was more time consuming for key-pressing sequences than for single key-press tasks. Experiment 2 examined whether the INT costs resulting from the increase in sequence length observed in Experiment 1 resulted from independent planning of each sequence element or via a separate "multiplier" process that handled repetitions of elements of the same duration. Findings from Experiment 2, in which participants performed single key presses or double or triple key sequences of the same duration, suggested that INT is involved with the independent organization of each element contained in the sequence. Researchers offer an elaboration of the 2-process account of motor programming to incorporate the present findings and the findings from other recent sequence-learning research.  相似文献

Abstract: This critical examination of Roderick Chisholm's agent causal brand of libertarianism develops a problem about luck that undermines his earlier and later libertarian views on free will and moral responsibility and defends the thesis that a modest libertarian alternative considerably softens the problem. The alternative calls for an indeterministic connection in the action‐producing process that is further removed from action than Chisholm demands. The article also explores the implications of a relatively new variant of a Frankfurt‐style case for Chisholm's views of free will and moral responsibility and for libertarianism in general. It is suggested that Chisholm's efforts will and should continue to offer important assistance to libertarians who are determined to succeed where he apparently fell short.  相似文献

Essentially the seventies – keen on experimenting – have given birth to the audiovisually supported psychoanalytical system of IS-TDP,developed by Habib Davanloo,Montreal. His unusual active and systematic challenge to the patient's resistances voids the absorbing complications of a transferenceneurosis by initiating three psychodynamic changes: intensification and cristallization of the defenses,prominent rise of mixed transference feelings, revival of an unconscious therapeutic coalition.This leads to a highly compressed transference-dynamic that finally discharges into an unresisting breakthrough of deeply repressed feelings: components of primitive rage, tenderness and pain.The patient's intrapsychic process itself replaces the therapist by an important person of the past.Repeatedly working through the emerging guilt is the most determinant factor now and during the whole therapy.The initial-interview already creates valuable connections to the unconscious and designates the further process until the pathogenic core structure is melted.Thus shortness of therapy is a methodical result.  相似文献

The efficiency of traditional levers and of modern touchscreen technology for training rats on a computerized visual discrimination was studied in a series of observations. When compared with a lever-based discrimination procedure, the use of touchscreens supported the faster development of signal tracking behavior and acquisition of a two-stimulus simultaneous visual discrimination. It did not affect the final level of accuracy. Factors related to spatial proximity of the responses with the stimuli, sign-tracking, and increased ease of touchscreen motor responses were suggested as possible reasons for the touchscreen training advantage. This increased efficiency allows large numbers of animals to be tested quickly, a necessary requirement for studies involving genetic and physiological interventions.  相似文献

To what extent should an analysis of an agent’s being morally responsible for an action that he performed—especially a compatibilist analysis of this—be sensitive to the agent’s history? In this article, I give the issue a clearer focus than it tends to have in the literature, I lay some groundwork for an attempt to answer the question, and I motivate a partial but detailed answer.  相似文献

The film “Slumdog Millionaire” when viewed together with the earlier “Salaam Bombay!” penetrates into the cultural psychology of urban India, revealing continuity with traditional Indian esthetic theories and commonality with psychoanalytic self psychologies. In films where plot is secondary and character is everything, we are led deep into the essence of the heroes’ feelings and learn to appreciate how being loyal to affect points the way to selfhood. Both films explore the psyches of boys struggling to hold on to fundamental “blueprints” of selfhood in the face of environments which seem to deny them any chance of fulfillment. While “Salaam Bombay!” presents a tragic and depressive response to the trauma and deprivation of slum life, “Slumdog Millionaire” appears grandiose and manic. Beneath the surface, both films sustain faith that these children can and will find the families they need to flourish. While hope is deferred in “Salaam!” it is ultimately achieved in “Slumdog.”  相似文献

The combined effects of testosterone and social experience from the time of hatching on development of aggressive behaviors in Cyprinodon variegatus were investigated. Social experience was defined as a rearing condition allowing visual, tactile, chemosensory, and auditory contact with zero, three, or 15 additional conspecifics. Behaviors were videotaped once weekly from 3 weeks to 4 months post-hatching, using the focal animal method, and an ethogram was constructed. At 3 months post-hatching, half the fish were injected once with testosterone propionate (2 μg/g b. w., i. p., vehicle-Ringer's solution) and the other half were injected with Ringer's isotonic saline solution. Testosteronetreated subjects showed significantly greater frequencies and durations of behaviors that may be related to aggression than did saline controls. Two weeks after the treatments, a round-robin tournament was conducted between testosterone- and saline-treated fish from each rearing condition. Testosterone-treated fish won significantly more encounters than did saline-treated subjects over all rearing conditions. Furthermore, significantly more aggressive acts were displayed by fish raised in the groups of 16 and the groups of four than did the Isolates. Although the number of aggressive acts exhibited by the group of 16 was greater than the group of four, the difference was not statistically significant.  相似文献
