Jesse Prinz has argued that a proxy type theory of concepts provides what he calls the 'intentionality' and 'cognitive content' desiderata better than any current competitor, and that the hybrid nature of proxytypes allows his theory to combine the informational component of informational atomism with the view that concepts are semantically structured entities. In response, I argue that the hybrid character of proxytypes, far from delivering the advantages Prinz claims, generates a threatening dilemma: either his theory is novel but fails to deliver the intentionality and cognitive content desiderata, or it delivers these desiderata but is not novel. 相似文献

The present study examines source memory for actions (e.g., placing items in a suitcase). For both young and older adult participants, source memory for actions performed by the self was better than memory for actions performed by either a known (close) or unknown other. In addition, neither young nor older adults were more likely to confuse self with close others than with unknown others. Results suggest an advantage in source memory for actions performed by the self compared to others, possibly associated with sensorimotor cues that are relatively preserved in aging. 相似文献

When trained to peck a selected position in a sagittally-oriented series of identical food containers, and then required to generalize to an identical series rotated by 90°, chicks identify as correct only the target position from the left end, while choosing the right one at chance. Here we show that when accustomed to systematic changes in inter-elements distances during training or faced with similar spatial changes at test, chicks identify as correct both the target positions from left and right ends. However, ordinal position is spontaneously encoded even when inter-element distances are kept fixed during training (in spite of the fact that distances between elements suffice for target identification without any numerical computation). We explain these findings in terms of intra-hemispheric coupling of bilateral numerical (ordinal) representation and unilateral (right hemispheric) spatial representation of the number line, producing differential allocation of attention in the left and right visual hemifields. 相似文献

One of the procedures used most recently with longitudinal data is linear mixed models. In the context of health research the increasing number of studies that now use these models bears witness to the growing interest in this type of analysis. This paper describes the application of linear mixed models to a longitudinal study of a sample of Spanish adolescents attending a mental health service, the aim being to investigate their knowledge about the consumption of alcohol and other drugs. More specifically, the main objective was to compare the efficacy of a motivational interviewing programme with a standard approach to drug awareness. The models used to analyse the overall indicator of drug awareness were as follows: (a) unconditional linear growth curve model; (b) growth model with subject-associated variables; and (c) individual curve model with predictive variables. The results showed that awareness increased over time and that the variable 'schooling years' explained part of the between-subjects variation. The effect of motivational interviewing was also significant. 相似文献

Several subjects with Specific Language Impairment (SLI) show communicative and pragmatic problems. In this study, we suggested that mentalistic comprehension tasks would help us to find a deteriorated pragmatic profile among the population with SLI. To achieve this goal, a group of participants with conventional SLI (n=11) was compared to a group of SLI with more pragmatic problems (n=9) and their respective control group with typically developed language (n=13), of ages between 4 and 7 years. Results revealed that all the groups were able to attribute mental states in tasks where the context was structured. However, the subjects with predominant pragmatic SLI showed poorer performance than those with conventional SLI when tasks were communicative-oriented and they needed to process non-explicit information from the context. These findings suggest that it is possible to isolate a SLI subtype with more pragmatic problems and also that we can use mentalistic tasks to assess these difficulties more accurately. 相似文献

Visual scenes contain many statistical regularities such as the likely identity and location of objects that are present; with experience, such regularities can be encoded and can ultimately facilitate the deployment of spatial attention to important locations. Memory-guided attention has been extensively examined in adults with the 'contextual cueing' paradigm and has been linked to specific neural substrates – a medial temporal lobe (MTL)-frontoparietal network. However, it currently remains unknown when this ability comes 'online' during development. Thus, we examined the performance of school-aged children on an age-appropriate version of the contextual cueing paradigm. Children searched for a target fish among distractor fish in new displays and in 'old' displays on a touchscreen computer. Old displays repeated across blocks of trials and thus provided an opportunity for prior experience with the invariant configuration of the stimuli to guide attentional deployment. We found that over time children searched old displays significantly faster than new displays, thus revealing intact memory-guided attention and presumed function of an MTL-frontoparietal network in 5- to 9-year-olds. More generally, our findings suggest that children are remarkably sensitive to the inherent structure of their visual environment and this enables attentional deployment to become more efficient with experience. 相似文献

The main objective of this study is to investigate the abstract-concrete dichotomy by introducing a new variable: the mode
of acquisition (MoA) of a concept. MoA refers to the way in which concepts are acquired: through experience, through language,
or through both. We asked 250 participants to rate 417 words on seven dimensions: age of acquisition, concreteness, familiarity,
context availability, imageability, abstractness, and MoA. The data were analyzed by considering MoA ratings and their relationship
with the other psycholinguistic variables. Distributions for concreteness, abstractness, and MoA ratings indicate that they
are qualitatively different. A partial correlation analysis revealed that MoA is an independent predictor of concreteness
or abstractness, and a hierarchical multiple regression analysis confirmed MoA as being a valid predictor of abstractness.
Strong correlations with measures for the English translation equivalents in the MRC database confirmed the reliability of
our norms. The full database of MoA ratings and other psycholinguistic variables may be downloaded from http:// brm.psychonomic-journals.org/content/supplemental

Chicks were trained to discriminate small sets of identical elements. They were then tested for choices (unrewarded) between sets of similar numerosities, when continuous physical variables such as spatial distribution, contour length, and overall surface were equalized. In all conditions chicks discriminated one versus two and two versus three stimulus sets. Similar results were obtained when elements were presented under conditions of partial occlusion. In contrast, with sets of four versus five, four versus six, and three versus four elements chicks seemed unable to discriminate on the basis of number, although nonnumerical discrimination based on perceptual cues was observed. This adds to increasing evidence for discrimination of small numerosities of up to three elements in human infants and nonhuman animals. 相似文献

Three experiments investigated functional asymmetries related to self-recognition in the domain of voices. In Experiment 1, participants were asked to identify one of three presented voices (self, familiar or unknown) by responding with either the right or the left-hand. In Experiment 2, participants were presented with auditory morphs between the self-voice and a familiar voice and were asked to perform a forced-choice decision on speaker identity with either the left or the right-hand. In Experiment 3, participants were presented with continua of auditory morphs between self- or a familiar voice and a famous voice, and were asked to stop the presentation either when the voice became "more famous" or "more familiar/self". While these experiments did not reveal an overall hand difference for self-recognition, the last study, with improved design and controls, suggested a right-hemisphere advantage for self-compared to other-voice recognition, similar to that observed in the visual domain for self-faces. 相似文献

The objective of the current study was to evaluate disease-related beliefs, adherence to treatment, quality of life, coping
strategies and cognitive status in a group of Brazilian patients with Temporomandibular Disorder (TMD). Thirty patients were
evaluated with a semi-directed interview, the Coping Strategies Inventory, and a Mini-Mental State Examination. Although half
(50%) of the patients had known their diagnosis long term, 40% of the sample were not correctly following proposed treatment.
All patients had a similar pattern of pain behavior related to TMD, while disease-related beliefs, quality of life and coping
strategies were variable. Expectations about treatment also had significant association with treatment adherence. The findings
of this study suggest that a more thorough understanding of individual differences in TMD is warranted. 相似文献
