Individual differences in adult decision-making competence 总被引:1,自引:0,他引:1
Bruine de Bruin W Parker AM Fischhoff B 《Journal of personality and social psychology》2007,92(5):938-956
The authors evaluated the reliability and validity of a set of 7 behavioral decision-making tasks, measuring different aspects of the decision-making process. The tasks were administered to individuals from diverse populations. Participants showed relatively consistent performance within and across the 7 tasks, which were then aggregated into an Adult Decision-Making Competence (A-DMC) index that showed good reliability. The validity of the 7 tasks and of overall A-DMC emerges in significant relationships with measures of socioeconomic status, cognitive ability, and decision-making styles. Participants who performed better on the A-DMC were less likely to report negative life events indicative of poor decision making, as measured by the Decision Outcomes Inventory. Significant predictive validity remains when controlling for demographic measures, measures of cognitive ability, and constructive decision-making styles. Thus, A-DMC appears to be a distinct construct relevant to adults' real-world decisions. 相似文献

Revisions of common associative learning models incorporate a within-compound association mechanism in order to explain retrospective cue competition effects (e.g., [Dickinson, A., & Burke, J. (1996). Within-compound associations mediate the retrospective revaluation of causality judgements. Quarterly Journal of Experimental Psychology, 49B, pp. 60-80.]). These models predict a correlation between memory for compounds (as a measure for the strength of within-compound associations) and retrospective cue competition but not forward cue competition. This was indeed found in a study of [Melchers, K. G., Lachnit, H., & Shanks, D. (2004). Within-compound associations in retrospective revaluation and in direct learning: A challenge for comparator theory. Quarterly Journal of Experimental Psychology, 57B, pp. 25-54.]. We argue that a higher-order reasoning account of causal learning can also explain the evidence for the role of within-compound associations in cue competition. Moreover, this account predicts that if making inferences during the learning stage is impeded, a correlation between memory for compounds and forward cue competition should be found as well. The results of a new study confirmed this prediction. 相似文献

This study analyses the data obtained from a sample of 220 healthy full-term neonates evaluated with the Neonatal Behavioral Assessment Scale, NBAS, 3rd edition. Standard scores were obtained for each of the 35 behavioral items and analysis of the main components of all the clusters was performed. Similarly to the original scale, the five following factors were obtained: Autonomic and Motor Systems, Habituation, State Organization, State Regulation, and Social Interactive. The analysis of the reliability of these groupings reveals that it is between moderate and high (the average Cronbach's alpha coefficient was .78). 相似文献

Research approaches leading to the understanding of the terrorist phenomenon are suggested. Seven principles explaining terrorism are analysed from a psychosocial approach: They could complete the explanations of terrorism focused in socio-structural and psychological variables, the latter being insufficient and often erroneous. Thus, terrorism is presented as a strategy of political influence, and the psychological attributes of terrorists are explained as the result of several influential social processes. We considered that terrorist attacks and campaigns correspond to strategic reasons, but we also assume that the rationality of the terrorists perspective is limited. As far as the organisational parameters are concerned, we propose an analogy with ordinary social movements, especially relating to their ideological frameworks of legitimisation and resource mobilization processes. 相似文献

The auditory cortex of nonhuman primates is comprised of a constellation of at least twelve interconnected areas distributed across three major regions on the superior temporal gyrus: core, belt, and parabelt. Individual areas are distinguished on the basis of unique profiles comprising architectonic features, thalamic and cortical connections, and neuron response properties. Recent demonstrations of convergent auditory-somatosensory interactions in the caudomedial (CM) and caudolateral (CL) belt areas prompted us to pursue anatomical studies to identify the source(s) of somatic input to auditory cortex. Corticocortical and thalamocortical connections were revealed by injecting neuroanatomical tracers into CM, CL, and adjoining fields of marmoset (Callithrix jacchus jacchus) and macaque (Macaca mulatta) monkeys. In addition to auditory cortex, the cortical connections of CM and CL included somatosensory (retroinsular, Ri; granular insula, Ig) and multisensory areas (temporal parietal occipital, temporal parietal temporal). Thalamic inputs included the medial geniculate complex and several multisensory nuclei (suprageniculate, posterior, limitans, medial pulvinar), but not the ventroposterior complex. Injections of the core (A1, R) and rostromedial areas of auditory cortex revealed sparse multisensory connections. The results suggest that areas Ri and Ig are the principle sources of somatosensory input to the caudal belt, while multisensory regions of cortex and thalamus may also contribute. The present data add to growing evidence of multisensory convergence in cortical areas previously considered to be 'unimodal', and also indicate that auditory cortical areas differ in this respect. 相似文献

When accepting a parcel from another person, we are able to use information about that person’s movement to estimate in advance
the weight of the parcel, that is, to judge its weight from observed action. Perceptual weight judgment provides a powerful
method to study our interpretation of other people’s actions, but it is not known what sources of information are used in
judging weight. We have manipulated full form videos to obtain precise control of the perceived kinematics of a box lifting
action, and use this technique to explore the kinematic cues that affect weight judgment. We find that observers rely most
on the duration of the lifting movement to judge weight, and make less use of the durations of the grasp phase, when the box
is first gripped, or the place phase, when the box is put down. These findings can be compared to the kinematics of natural
box lifting behaviour, where we find that the duration of the grasp component is the best predictor of true box weight. The
lack of accord between the optimal cues predicted by the natural behaviour and the cues actually used in the perceptual task
has implications for our understanding of action observation in terms of a motor simulation. The differences between perceptual
and motor behaviour are evidence against a strong version of the motor simulation hypothesis.

Bloomfield''s “Linguistics as a Science” (1930/1970), Language (1933/1961), and “Language or Ideas?” (1936a/1970), and Skinner''s Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two authors were found. In particular both asserted that (a) the study of language must be carried out through the methods of science; (b) the main function of language is to produce practical effects on the world through the mediation of a listener; and (c) a physicalist conception of meaning. Their differences concern the subject matter of their disciplines and their use of different models for the analysis of behavior. Bloomfield''s linguistics and Skinner''s functional analysis of verbal behavior are complementary approaches to language. 相似文献
