Development of visual working memory precision in childhood 总被引:1,自引:0,他引:1

Visual working memory (VWM) is the facility to hold in mind visual information for brief periods of time. Developmental studies have suggested an increase during childhood in the maximum number of complete items that can simultaneously be stored in VWM. Here, we exploit a recent theoretical and empirical innovation to investigate instead the precision with which items are stored in VWM, where precision is a continuous measure reflecting VWM resolution. Ninety boys aged 7 to 13 years completed one-item and three-item VWM tasks in which stimuli were coloured bars varying in orientation. On each trial, participants used a rotating dial to reproduce the probed stimulus from memory. Results show linear age-related improvement in recall precision for both one-item and three-item VWM tasks. However, even the youngest age group stored a significant amount of information about all three items on the difficult 3-item VWM task. Importantly, the development of VWM precision was not accounted for by development on a sensorimotor control task. Whereas storage of a single complete item was previously thought to be well within the capacity limitations of the current age range, these results suggest protracted development during childhood and early adolescence in the resolution with which single and multiple items are stored in VWM. Probabilistic modelling of response distribution data suggests that improvement in VWM performance is attributable to a specific decrease in variability of stored feature representations, rather than to a decrease in misbinding or random noise. As such, we highlight a novel, potentially developmentally plausible mechanism that may underlie developmental improvement in VWM performance, independent of any alterations in the maximum number of complete items which can be stored. 相似文献

This paper illustrates the value of the individual analyst's deep knowledge of the patient in a couple setting; describes how the analyst informed by many theoretical perspectives decided to work in different modalities (individual, group, couple) with the same patient; and discusses when such additions would have been contraindicated as well as what could have been the consequences if the analyst did not attune to the patient's need for “optimum space” or follow the direction of the patient's creative gestures. 相似文献

Cognitive dysfunction is well known in patients suffering from multiple sclerosis (MS) and has been described for many years. Cognitive impairment, memory, and attention deficits seem to be features of advanced MS stages, whereas depression and emotional instability already occur in early stages of the disease. However, little is known about processing of affective prosody in patients in early stages of relapsing–remitting MS (RRMS). In this study, tests assessing attention, memory, and processing of affective prosody were administered to 25 adult patients with a diagnosis of RRMS at an early stage and to 25 healthy controls (HC). Early stages of the disease were defined as being diagnosed with RRMS in the last 2 years and having an Expanded Disability Status Scale (EDSS) of 2 or lower. Patients and HC were comparable in intelligence quotient (IQ), educational level, age, handedness, and gender. Patients with early stages of RRMS performed below the control group with respect to the subtests ‘discrimination of affective prosody’ and ‘matching of affective prosody to facial expression’ for the emotion ‘angry’ of the ‘Tübingen Affect Battery’. These deficits were not related to executive performance. Our findings suggest that emotional prosody comprehension is deficient in young patients with early stages of RRMS. Deficits in discriminating affective prosody early in the disease may make misunderstandings and poor communication more likely. This might negatively influence interpersonal relationships and quality of life in patients with RRMS. 相似文献

The integration of visual and auditory inputs in the human brain works properly only if the components are perceived in close temporal proximity. In the present study, we quantified cross-modal interactions in the human brain for audiovisual stimuli with temporal asynchronies, using a paradigm from rhythm perception. In this method, participants had to align the temporal position of a target in a rhythmic sequence of four markers. In the first experiment, target and markers consisted of a visual flash or an auditory noise burst, and all four combinations of target and marker modalities were tested. In the same-modality conditions, no temporal biases and a high precision of the adjusted temporal position of the target were observed. In the different-modality conditions, we found a systematic temporal bias of 25–30 ms. In the second part of the first and in a second experiment, we tested conditions in which audiovisual markers with different stimulus onset asynchronies (SOAs) between the two components and a visual target were used to quantify temporal ventriloquism. The adjusted target positions varied by up to about 50 ms and depended in a systematic way on the SOA and its proximity to the point of subjective synchrony. These data allowed testing different quantitative models. The most satisfying model, based on work by Maij, Brenner, and Smeets (Journal of Neurophysiology 102, 490–495, 2009), linked temporal ventriloquism and the percept of synchrony and was capable of adequately describing the results from the present study, as well as those of some earlier experiments. 相似文献

We propose that actors will perceive justice as more important with respect to a target when they experience moderate versus extremely high or extremely low connection with the target. In two studies, we manipulated actors’ connection with (e.g., similarity to) a target and the target's standing on the appropriate justice criterion. Both studies yielded the predicted curvilinear relation between connectedness and the perceived relevance of justice. In Study 2, actors’ decisions were more affected by the justice criterion in the moderate versus extreme connectedness conditions. Our findings have important implications for the interplay between connection with others and moral motivations. 相似文献

Across a series of studies, an effort was made to operationalize optimism in a spiritually nuanced fashion. In the first study, it was proposed and tested that spiritual optimism might consist of two factors: “here and now” and “end of story” optimism. However, a second study suggested that spiritual optimism had more of a unitary quality. The second study also suggested that the construct of spiritual optimism was separate from the construct of hope. The third study confirmed the unitary nature of the spiritual optimism measure and provided evidence for the construct validity of the measure. Spiritual optimism was directly related to a general measure of coping and a measure of religious coping. The relationships between spiritual optimism and different types of religious coping appeared stronger than between spiritual optimism and the more general measures of coping. 相似文献

Self and ego boundary changes critical to the development of depression are hypothesized to have occurred in the second six months of life. An analysis of these changes suggested that persons prone to depression tend to form interpersonal relations combining intense intimacy with sharp separation. Hypotheses concerning the manifestations on the Rorschach test of these relationships and attendant concerns were supported at a satisfactory level of statistical significance. 相似文献

Assessing couple relationships across diverse languages and cultures has important implications for both clinical intervention and prevention. This is especially true for nontraditional relationships potentially subject to various expressions of negative societal evaluation or bias. Few empirically validated measures of relationship functioning have been developed for cross‐cultural applications, and none have been examined for their psychometric sufficiency for evaluating same‐sex couples across different languages and cultures. The current study examined the psychometric properties of an Italian translation of the Marital Satisfaction Inventory – Revised (MSI‐R), a 150‐item 13‐scale measure of couple relationship functioning, for its use in assessing the intimate relationships of gay and lesbian couples in Italy. Results for these couples were compared to data from heterosexual married and unmarried cohabiting couples from the same geographical region, as well as to previously published data for gay, lesbian, and unmarried heterosexual couples from the United States. Findings suggest that, despite unique societal pressures confronting Italian same‐sex couples, these relationships appear resilient and fare well both overall and in specific domains of functioning compared to heterosexual couples both in Italy and the United States. 相似文献
