This paper examines the association of cardiovascular reactivity with thermal thresholds (detection and unpleasantness). Heart period (HP), systolic (SBP) and diastolic (DBP) blood pressure of 42 health young males were recorded during a cardiovascular reactivity task (a videogame based upon Sidman's avoidance paradigm). Thermal sensitivity, assessing detection and unpleasantness thresholds with radiant heat in the forearm was also estimated for participants. Participants with differential scores in the cardiovascular variables from base line to task > or = P65 were considered as reactors and those how have differential scores < or = P35 were considered as non-reactors. Significant differences were observed between groups in the unpleasantness thresholds in blood pressure (BP) but not in HP. Reactors exhibited significant higher unpleasantness thresholds than non-reactors. No significant differences were obtained in detection thresholds between groups. 相似文献

The quality of infant-mother attachment has been linked to competence in different domains of child development. Research indicates that early intervention can enhance the quality of infant-mother attachment, though its efficacy in a group format has yet to be evaluated. The current study is aimed at examining the usefulness of a group intervention in enhancing infant-mother attachment. An intervention aimed at addressing aspects such as maternal responsivity, sensitivity and childrearing behaviour was developed by the researchers and experienced psychologists. The intervention spanned a period of 14 months starting from the third quarter of pregnancy. The intervention was evaluated among 24 mothers from the Basque region of Spain. The sample consisted of children of both genders in a similar proportion: 45.8% were boys and 54.2% were girls. The children in this sample were full-term born and did not present symptoms of any serious pre- or postnatal complications. The intervention had a statistically non-significant medium effect. Infants whose mothers had received the intervention showed higher rates of secure attachment compared to children from the control group, as assessed by the Strange Situation observation procedure. A potentially significant confounding variable, maternal attachment, was balanced across the intervention and comparison groups. We can tentatively point out that a group intervention may enhance the quality of infant-mother attachment. Nevertheless, because the study design was not randomized, the results of this study remain preliminary and need replication in a full randomized controlled trial designed study. 相似文献

The aim of this paper was to develop an instrument to assess levels of stress experienced by Latin-American immigrants in their acculturative process in Spain. A sample of 692 immigrants from Latin America, aged 20 to 63 years, took part on this study (54.9% males and 45.1% females). A 24-item questionnaire with high reliability (.92) was elaborated. Six factors related to acculturative stress were found: 1) discrimination and rejection; 2) differences with the out-group (native Spaniards); 3) citizenship problems and legality; 4) problems concerning social relationships with other immigrants; 5) nostalgia and longing; and 6) family break-up. Our findings show that participants have a high level of stress related to nostalgia and longing, family break-up, and the perception of discrimination and rejection by natives. The usefulness of the instrument and its applications and restrictions are discussed. 相似文献

The purpose of this paper is to analyse the Spanish mobile phone industry to determine how mobile phone companies and certain
institutions can improve protection for children who use mobile phones. We carried out a multivariate statistical analysis
using anonymous primary data from mobile phone companies, and institutions and associations that protect children, to compare
these stakeholders’ opinions and to put forward solutions. We proved that, even though some European countries have made an
effort to provide safer ICT services, all stakeholders still need to cooperate and agree on solutions to the commercial problems
associated with children using mobile phones. This can be done by signing codes of conduct. We found that even though some
companies implement measures to protect children from accessing harmful content via their mobile phones, they do so for reasons
of legal and not social responsibility. 相似文献

Great apes can use multiple tools to extract food embedded in substrates and can invent new ways to exploit those resources.
We tested five bonobos, five chimpanzees, and six orangutans in a task in which they had to use (and modify) a tool as a straw
to drink the juice located inside a container. Experiment 1 showed that four orangutans and one chimpanzee invented the use
of a piece of electric cable to get the juice. Experiment 2 investigated whether subjects could transform a non-functional
hose into a functional one by removing blockages that impeded the free flow of juice. Orangutans outperformed chimpanzees
and bonobos by differentially removing those blockages that prevented the flow of juice, often doing so before attempting
to extract the juice. In Experiment 3, we presented chimpanzees and orangutans with four 3-tool sets (each tool set contained
a single straw-like tool) and allowed them to select one tool. Unlike chimpanzees, orangutans succeeded in selecting the straw-like
tool above chance levels without having to physically manipulate it. We suggest that orangutans’ superior performance is related
to their greater reliance on mouth actions during foraging. Experiment 4 investigated whether orangutans were also capable
of selecting the suitable tool not by its appearance, but by the effects that it produced. After witnessing the experimenter
blow bubbles or absorb liquid with a functional tool but fail to accomplish the same thing with the non-functional tool, orangutans
failed to select the functional tool above chance levels. 相似文献

Throughout adolescence, children begin to develop their life story: a coherent account of their experiences and selfhood. Although the nature of this development is still being uncovered, one promising direction for research is the examination of factors that could encourage life story development. Here the authors explore the idea that exposure to the literary arts (i.e., poetry and fictional literature) might promote the formation of a coherent autobiographical narrative. Taking a critical look at both theoretical proposals along with the current empirical research, they provide a brief survey of this intriguing hypothesis. 相似文献

Wild capuchin monkeys select stone tools to crack open nuts on the basis of their weight and friability, two non-visual functional
properties. Here, we investigated whether they would select new stick-like tools on the basis of their rigidity. In Experiment
1, subjects faced an out-of-reach reward and a choice of three unfamiliar tools differing in color, diameter, material, and
rigidity. In order to retrieve the reward, capuchins needed to select the rigid tool exemplar. Capuchins gathered information
regarding tools’ pliability either by (1) manipulating the tools themselves (manipulation condition), (2) observing a human
demonstrator repeatedly bending the tools (observation condition), or (3) seeing the tools placed on a platform without any
manipulation taking place (visual static condition). Subjects selected the rigid tool above chance levels in both the manipulation
and observation conditions, but not in the visual static condition. In Experiment 2, subjects needed to select and use a flexible
tool to access a liquid reward (as opposed to the rigid tool, as in previous experiment). Again, capuchins selected above
chance levels the appropriate tool (i.e., flexible), thus demonstrating a good appreciation of the relation between the tool
properties and the task requirements. 相似文献

Earlier studies have demonstrated that spatial cueing differentially reduces stimulus-stimulus congruency (e.g., spatial Stroop) interference but not stimulus-response congruency (e.g., Simon; e.g., Lupiá?ez & Funes, 2005). This spatial cueing modulation over spatial Stroop seems to be entirely attributable to object-based attention (e.g., Luo, Lupiá?ez, Funes, & Fu, 2010). In the present study, two experiments were conducted to further explore whether the cueing modulation of spatial Stroop is object based and/or space based and to analyse the "locus" of this modulation. In Experiment 1, we found that the cueing modulation over spatial Stroop is entirely object based, independent of stimulus-response congruency. In Experiment 2, we observed that the modulation of object-based attention over the spatial Stroop only occurred at a short cue-target interval (i.e., stimulus onset asynchrony; SOA), whereas the stimulus-response congruency effect was not modulated either by object-based or by location-based attentional cueing. The overall pattern of results suggests that the spatial cueing modulation over spatial Stroop arises from object-based attention and occurs at the perceptual stage of processing. 相似文献

Abstract Evidence over the last 15 years has suggested that dual (imagery and verbal) coding explanations of concreteness effects in memory for word lists do not generalise well to memory for sentences and paragraphs. In contrast, an alternative framework based on relative differences in relational and distinctive processing has been shown to account for the effects of imagery and concreteness in these contexts and others. This paper describes recent research on free and cued recall of word lists and evaluates it with respect to the two models. The evidence suggests that whereas dual processing systems may be involved in the encoding of verbal materials, dual memory codes are insufficient to explain concreteness effects in recall. Better memory for high-as compared to low-imagery words depends on the use of paradigms that facilitate inter-item relational processing, independent of whether or not imagery is involved. 相似文献

Abstract Three experiments explored concreteness effects in memory for words following imagery-related orienting tasks. Predictions from dual coding and relational-distinctive explanations of concreteness and imagery effects were contrasted. Of particular interest were differences in the magnitudes of concreteness effects in an item-specific imagery task (timed image generation) and a relational imagery task (rating of relative imageability). The effects of restricted-range (high and medium-imagery) versus full-range (high, medium and low-imagery) materials were also considered as a means to evaluate the effects of relative item distinctiveness on concreteness effects. The results demonstrated the importance of relational information in the production of concreteness effects and indicated that imagery alone is an insufficient explanation of concreteness effects. At the same time, they revealed the need for a more comprehensive theoretical account of the role of mental imagery in memory, as neither model under consideration could account for all of the present findings. 相似文献
