In a running memory span task, the participants are presented with a list of items (e.g. numbers or words) of an unknown length, because this length varies from trial to trial. In one variation of the procedure the participants must report a certain fixed number of items (e.g. four) from the end of the list. According to Morris and Jones (British Journal of Psychology, 81, 111-121, 1990), the recalled items must be updated in memory as the presentation of the list progresses. Ruiz, Elosúa and Lechuga (The Quarterly Journal of Experimental Psychology, 5, 887-905, 2005) noted that an active strategy implies an inhibition in memory of the final discarded items, and did not find results which supported this hypothesis. The aim of this study is to check whether or not participants adopt an active processing strategy in extreme conditions. Experiment 1 uses catch trials, which induce the participants not to discard the first items of the lists, and also short lists (of 4, 7, 8, 9 and 10 items); these could be considered optimal conditions for updating. However, it should also be pointed out that with an upper limit of 10 items per list, participants could try to memorise the whole list in most of the trials. One way to discourage this strategy is including lists well over span (e.g. 14-26 items). The purpose of Experiment 2 was to analyse the 10-item lists in two conditions: within a context of much longer lists (well over span) in most of the trials and within a context of shorter lists (data of Experiment 1). Results in both experiments, from the analysis of location errors, indicate that even in these conditions the participants do not seem to carry out the supposed active updating of the memory set. 相似文献

From the neighborhoods we live in to those we marry, other people are a part of our everyday lives. Mounting evidence suggests that these social factors constitute risk and resilience influences for coronary heart disease (CHD). The current aim is to summarize the literature into four representative categories relating to CHD risk: social environments, social roles, social resources, and close relationships. The argument is made that these factors moderate and mediate stress and associated physiological responses constituting a psychosomatic pathway to disease. 相似文献

Both your intention and mine are reflected in the kinematics of my reach-to-grasp movement 总被引:1,自引:0,他引:1
The aim of the present study is to ascertain whether in a social context the kinematic parameters are influenced by the stance of the participants. In particular, we consider two basic modes of social cognition, namely cooperation and competition. Na?ve subjects were asked either to cooperate or to compete with a partner (a professional female actor), whose attitude could be either congruent or incongruent with the task instructions. Thus, on congruent conditions, subjects cooperated or competed with a partner showing a congruent cooperative or competitive attitude. On incongruent trials, the partner assumed an attitude that was manifestly in contrast with the instruction: competitive for the cooperative task, cooperative for the competitive task. We hypothesized that this mismatch between partner's attitude and instruction would produce a sort of unexpected social situation, affecting the kinematics of reach-to-grasp movement performed by the agents. If cooperative and competitive kinematic patterns are sensitive to the partner's attitude, then we should expect that an incongruent attitude have the potency to determine a reversal in kinematic patterning. Results revealed that for the incongruent trials the specific kinematic patterns for cooperation and competition found for the congruent conditions where modified according to the incongruent attitude assumed by the model actor. We suggest that this 'attitude' contagion is part of a sophisticated system that allows us to infer about the intention to act in a social context. 相似文献

Few studies to date have examined the extent to which borderline personality features are best construed as representing an underlying dimension or a discrete class or taxon. The authors conducted taxometric analyses using a large-scale sample of male (n=787) and female (n=368) prison inmates who had completed the Personality Assessment Inventory (L. C. Morey, 2007). Analyses based on the 4 subscales of the Borderline Features Scale offered compelling support for a dimensional structure in both the full sample and the female subsample--even after controlling for the potentially confounding effects of negative response distortion. Theoretical and pragmatic implications of these findings are reviewed. 相似文献

The role of morphology in reading aloud was examined measuring naming latencies to pseudowords and words composed of morphemes (roots and derivational suffixes) and corresponding simple pseudowords and words. Three groups of Italian children of different ages and reading abilities, including dyslexic children, as well as one group of adult readers participated in the study. All four groups read faster and more accurately pseudowords composed of root and suffix than simple pseudowords (Experiment 1). Unlike skilled young and adult readers, both dyslexics and younger children benefited from morphological structure also in reading aloud words (Experiment 2). It is proposed that the morpheme is a unit of intermediate grain size that proves useful in processing all linguistic stimuli, including words, in individuals with limited reading ability (dyslexics and younger readers) who did not fully develop mastering of whole-word processing. For skilled readers, morphemic parsing is useful for reading those stimuli (i.e., pseudowords made up of morphemes), for which a whole-word lexical unit does not exist; where such whole-word lexical units do exist, skilled readers do not need to rely on morphological parsing because they can rely on a lexical (whole-word) reading unit that is larger than the morpheme. 相似文献

The aim of the present study was to evaluate the occurrence of fear sensitization in rats previously treated with an inhibitor of the NO syntheses and submitted to Trial1/Trial2 plus-maze (PM) procedure. Male Wistar rats received a systemic treatment with N(omega)-nitro-L-Arginine-methyl ester (L-NAME; 5, 10 or 50 mg kg(-1)) and were submitted to PM Trial1. In the following day the animals were re-exposed to the PM with no drug administration (Trial2). Some standards spatial-temporal measures, such as the percentage of entries (% Open arm entries) and time spent (% Open arm time) in the open arms and risk assessment frequency were recorded and used to estimate the animal level of fear sensitization in PM Trial2. The results showed that animals receiving L-NAME (50 mg kg(-1)) displayed increased % Open arm entries and % Open arm time in Trial2 in relation to the group receiving 0.9% saline, which is compatible with impaired fear/anxiety acquisition during Trial1/Trial2 PM procedure. In addition, rats treated with L-NAME (50 mg kg(-1)) exhibited low level of risk assessment in Trial2 in relation to the group treated with 0.9% saline, which indicates low level of fear/anxiety during PM re-exposure. The number of entries into the enclosed arms was not changed by any L-NAME treatment, which suggests no bias of the drug treatments on animal locomotor activity. The data suggest that NO synthesis may mediate the fear sensitization process in the PM. 相似文献

This study investigated the relation between phonological loop functioning and age. Phonological loop is a time-based subsystem of the Working Memory Model of Baddeley and Wilson, which uses rehearsal of information as an active process to avoid phonological decay. Performance differences were examined between young and older adults in two speech-based memory tasks, such as the immediate serial recall of words and the Digit Ordering Task. Analysis showed that performance on both tasks was lower for the older group. Articulation rate was also measured to test the hypothesis that the impairment of some cognitive functions in adults can be associated to their slowness or the greater time needed by older adults for the rehearsal process. A significant negative correlation was found for articulation rate with age. When the effect of articulation rate on Serial Recall and Digit Ordering Tasks was partialled out, the difference between the two groups was eliminated. 相似文献

The relationship between the subjective well-being of parents and their own 12–16-year-old children was explored in a Spanish
sample of N = 266 families. A positive relationship was expected due to both a shared environment and the possibility of the genetic
transmission of subjective well-being ‘set-points’. A positive significant relationship was found for the summated scale of
satisfaction domains forming the Personal Well-being Index, and for the specific domains of health and security for the future.
However, no relationship was found for the other five domains that make up this Index or for satisfaction with life as a whole.
We conclude while these results provide some evidence for the expected influence of a shared environment, they have failed
to provide evidence for high heritability of set-points for subjective well-being. 相似文献

The present work sets out to study the internal structure of the Torrance Test of Creative Thinking (TTCT) and to establish standardised scores that will enable the test to be used in both a diagnostic and educational context. 649 students (319 girls and 330 boys), aged 5 to 12 years from various schools in Murcia and Alicante (SE Spain), took part in the study. The findings suggest that the psychometric characteristics of TTCT are satisfactory, and its internal structure can be attributed to three factors that are responsible for a high percentage of the variance (73.8%). The standardised score tables, which are provided for first time in this context, will be useful in the evaluation of creativity and the identification of students with high intellectual abilities. 相似文献

This work presents a self-help, Internet-based telepsychology program for the treatment of public speaking fears. The system is comprised of 3 parts: The assessment protocol gives the patient information about his or her problem (i.e., amount of interference it creates in his or her life, severity, degree of fear and avoidance). The system also includes a structured treatment protocol, organized into separate blocks, reflecting the patient’s progress. This ensures that the patient does not skip any steps in the treatment (something quite common in traditional self-help manuals), which provides more control over the process. The treatment protocol is a cognitive-behavioral program that provides exposure to the feared situation using videos of real audiences. Finally, the control protocol assesses treatment efficacy, not only at closure, but also at every intermediate step. Efficacy data from 12 social phobia patients are presented from pretreatment to posttreatment and at 1-month follow-up. These preliminary data support the efficacy of our telepsychology program for the treatment of fear of public speaking. This is a preliminary work in a promising research path that examines the possibility of using the Internet for the treatment of psychological disorders. 相似文献
