According to the story model of Pennington and Hastie, jurors collect information at trial and modify it with general knowledge to create case stories. Schank and Ableson argue that human memory is organized to tell and understand stories. However, Finkel and Groscup questioned the use of manipulated, experimenter-constructed narratives to demonstrate the existence of multiple prototypical crime stories. We interviewed 76 jury eligible, death qualified citizens and asked them to imagine a first-degree murder scenario, describing the events that led to the killing. We coded the presence of dichotomous variables in the resulting stories and identified at least three shared story prototypes using cluster and profile analysis. We conclude that people do not store crime stories as simple prototypes and comment on the implications of this finding for legal decision-making. 相似文献

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words prompted more activity in left than in right DLPFC. Response speed to pleasant words was correlated with DLPFC activity. These data directly link positive affect, enhanced performance, and prefrontal activity, providing some of the first fMRI evidence supporting models of emotional valence and frontal brain asymmetry based on electroencephalography (EEG). 相似文献

Several recent reports suggest that the behavioral and cortical specificity of face processing may be influenced by experience.
To test this hypothesis, behavioral and electrophysiological data were recorded from adults in response to human and monkey
faces differing in familiarity and orientation. An analysis of event-related potential and behavioral data revealed differentiation
across species, familiarity, and orientation. Behavioral measures were correlated with amplitude and latency measures for
each factor of interest. These analyses revealed that accuracy was positively related to the amplitude of the vertex positive
potential in the human face task but not in the monkey face task. These findings suggest that previous experience with different
categories of faces modulates the link between behavioral and electrophysiological measures of face processing. 相似文献

How should biological behaviour be modelled? A relatively new approach is to investigate problems in neuroethology by building physical robot models of biological sensorimotor systems. The explication and justification of this approach are here placed within a framework for describing and comparing models in the behavioural and biological sciences. First, simulation models--the representation of a hypothesis about a target system--are distinguished from several other relationships also termed "modelling" in discussions of scientific explanation. Seven dimensions on which simulation models can differ are defined and distinctions between them discussed: 1. Relevance: whether the model tests and generates hypotheses applicable to biology. 2. Level: the elemental units of the model in the hierarchy from atoms to societies. 3. Generality: the range of biological systems the model can represent. 4. Abstraction: the complexity, relative to the target, or amount of detail included in the model. 5. Structural accuracy: how well the model represents the actual mechanisms underlying the behaviour. 6. Performance match: to what extent the model behaviour matches the target behaviour. 7. Medium: the physical basis by which the model is implemented. No specific position in the space of models thus defined is the only correct one, but a good modelling methodology should be explicit about its position and the justification for that position. It is argued that in building robot models biological relevance is more effective than loose biological inspiration; multiple levels can be integrated; that generality cannot be assumed but might emerge from studying specific instances; abstraction is better done by simplification than idealisation; accuracy can be approached through iterations of complete systems; that the model should be able to match and predict target behaviour; and that a physical medium can have significant advantages. These arguments reflect the view that biological behaviour needs to be studied and modelled in context, that is, in terms of the real problems faced by real animals in real environments. 相似文献

The topic of organ transplantation is examined from the perspective of three authors: Robert Bellah, Jeremy Rifkin, and Margaret Jane Radin. Introduced by reflections on the development of the justification of organ transplantation within the Roman Catholic community and the various themes raised by the historical study in Richard Titmuss's The Gift Relationship, the paper examines how and in what ways the possible commodification of organs will affect our society and the impacts this may have on the supply of organs. 相似文献

How do we come to recognize and represent different kinds of objects in the world? Some developmental psychologists have hypothesized that learning language plays a crucial role in this capacity. If this hypothesis were correct, then non-linguistic animals should lack the capacity to represent objects as kinds. Previous research with rhesus monkeys (Macaca mulatta) has shown that this species can successfully individuate different kinds of objects - monkeys who saw one kind of object hidden inside a box searched longer after finding a different kind of object. However, in these studies and the infant studies on which they were based, the objects to be individuated differed both in kind and in properties. Thus, subjects in these experiments may not be representing the kinds of objects per se, but instead only their immediate perceptual properties. Here, we show that rhesus monkeys successfully individuate different kinds of objects even when their perceptual properties are held constant. Although these data provide the best evidence to date that language is not necessary to represent kinds, we discuss our findings in terms of possible associative hypotheses as well. 相似文献

Two concurrent criterion‐related validity studies were conducted with blue‐collar workers employed in Australia. The first sample consisted of 77 unskilled and semi‐skilled manufacturing employees. The second sample consisted of 243 stockpeople who worked in piggeries. A range of work‐related criteria was used, and this range differed across the two studies. The results showed that Employment Inventory–Performance was a reasonable predictor of some aspects of supervisor ratings of work performance but unrelated to other aspects. A similar pattern of findings emerged with self‐ratings of work performance. Employment Inventory–Tenure was weakly related to turnover intentions and actual turnover. 相似文献
