In recalling a set of previously experienced events, people exhibit striking effects of recency, contiguity, and similarity: Recent items tend to be recalled best and first, and items that were studied in neighboring positions or that are similar to one another in some other way tend to evoke one another during recall. Effects of recency and contiguity have most often been investigated in tasks that require people to recall random word lists. Similarity effects have most often been studied in tasks that require people to recall categorized word lists. Here we examine recency and contiguity effects in lists composed of items drawn from 3 distinct taxonomic categories and in which items from a given category are temporally separated from one another by items from other categories, all of which are tested for recall. We find evidence for long-term recency and for long-range contiguity, bolstering support for temporally sensitive models of memory and highlighting the importance of understanding the interaction between temporal and semantic information during memory search. 相似文献

Some evidence points to an increased rate of cluster B and C personality disorders (PDs) in adult ADHD patients. In order to assess axis II disorders comprehensively we used the diagnostic instrument of the WHO. In sixty adult out-patients with ADHD according to DSM-IV criteria PDs were assessed with the International PD Examination (IPDE) and severity of childhood ADHD with the Wender-Utah-Rating Scale (WURS). We found at least one PD in 25% of cases. Cluster C PDs were most common (36.6%) followed by Cluster B (23.3%) and A (8.3%). Avoidant (21.7%) and borderline (18.3%) were the most frequent single PD entities. ADHD patients with PD suffered from significantly more severe childhood ADHD compared to those without co-occurring PD. Applying the IPDE we confirmed a high number of PDs among adult ADHD patients. Our findings point to a higher vulnerability for the development of PDs in patients with severe childhood ADHD. 相似文献

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed. 相似文献

In many areas of science, research questions imply the analysis of a set of coupled data blocks, with, for instance, each block being an experimental unit by variable matrix, and the variables being the same in all matrices. To obtain an overall picture of the mechanisms that play a role in the different data matrices, the information in these matrices needs to be integrated. This may be achieved by applying a data‐analytic strategy in which a global model is fitted to all data matrices simultaneously, as in some forms of simultaneous component analysis (SCA). Since such a strategy implies that all data entries, regardless the matrix they belong to, contribute equally to the analysis, it may obfuscate the overall picture of the mechanisms underlying the data when the different data matrices are subject to different amounts of noise. One way out is to downweight entries from noisy data matrices in favour of entries from less noisy matrices. Information regarding the amount of noise that is present in each matrix, however, is, in most cases, not available. To deal with these problems, in this paper a novel maximum‐likelihood‐based simultaneous component analysis method, referred to as MxLSCA, is proposed. Being a stochastic extension of SCA, in MxLSCA the amount of noise in each data matrix is estimated and entries from noisy data matrices are downweighted. Both in an extensive simulation study and in an application to data stemming from cross‐cultural emotion psychology, it is shown that the novel MxLSCA strategy outperforms the SCA strategy with respect to disclosing the mechanisms underlying the coupled data. 相似文献

This study examined the efficacy of the written emotional disclosure (WED) procedure with a sample of young adults who met diagnostic criteria for posttraumatic stress disorder (PTSD). Participants were randomly assigned to either WED or a control writing condition and were assessed at baseline and one month following the writing sessions. During each writing session, participants’ heart rate was recorded; participants also provided self-report ratings of emotional responding. Findings indicated no significant group differences for PTSD and depression symptom severity at follow-up assessment. Relative to control participants, WED participants displayed significantly greater heart rate activity and reported greater emotional responding during the first writing session; however, no reduction in emotional responding occurred for either condition from the first to the last writing session. Taken together, these findings indicate that WED may not be an efficacious intervention for PTSD. Suggestions are made for future work in this area. 相似文献

Using data from the International Social Survey Programme, this research investigated asymmetric attitudes of ethnic minorities and majorities towards their country and explored the impact of human development, ethnic diversity, and social inequality as country‐level moderators of national attitudes. In line with the general hypothesis of ethnic asymmetry, we found that ethnic, linguistic, and religious majorities were more identified with the nation and more strongly endorsed nationalist ideology than minorities (H1, 33 countries). Multilevel analyses revealed that this pattern of asymmetry was moderated by country‐level characteristics: the difference between minorities and majorities was greatest in ethnically diverse countries and in egalitarian, low inequality contexts. We also observed a larger positive correlation between ethnic subgroup identification and both national identification and nationalism for majorities than for minorities (H2, 20 countries). A stronger overall relationship between ethnic and national identification was observed in countries with a low level of human development. The greatest minority‐majority differences in the relationship between ethnic identification and national attitudes were found in egalitarian countries with a strong welfare state tradition. 相似文献

The aim of this work was to examine the psychometric properties of the Spanish version of the "Recovery Experience Questionnaire" developed by Sonnentag and Fritz. The sample was made up of 941 professionals from the security sector. Results from the exploratory factor analysis suggested the possibility of considering a four-factor structure. Confirmatory factor analysis showed that the four-factor model with three correlated items each provided the best fit to the data (CFI=0.97, GFI=0.96, NNFI=0.96, RMSEA=0.05 y AIC=171.76). Therefore, the questionnaire maintains the four recovery experiences -psychological detachment from work, relaxation, mastery experiences and control over leisure time--but with 12 items instead of 16 items as in the original scale. Reliability analysis showed good internal consistency for this scale with Cronbach alpha coefficients for the factors ranging from .75 to .88. Significant correlations were found between the recovery experiences and various external variables, providing evidence of construct validity. Thus, this Spanish version shows adequate psychometric properties and may help to achieve a better understanding of this topic. 相似文献

The movement of defendants through the legal process who have been adjudicated incompetent to proceed is little studied, yet it is important. The purpose of this study was to provide empirical data regarding factors that affected the amount of time defendants adjudicated incompetent to proceed and ordered to undergo hospitalization remained in jail while awaiting transfer to a state hospital. Statewide data collected in Florida between July 2005 and June 2008 were used to determine the lengths of time incompetent defendants spent at certain stages in the legal process. The addition of forensic bed capacity following media attention and litigation resulted in a significant decrease in the amount of time defendants adjudicated incompetent to proceed waited in jail for transfer to a state hospital for treatment. The amount of time it took for completed commitment orders to be submitted to the state mental health authority by the Clerks of Court of each county accounted for a meaningful portion of days defendants spent in jail awaiting transfer to a state hospital, with considerable variation across counties with respect to waiting times. These findings reflect how various stakeholders can affect the amount of time defendants spend in jail while awaiting hospitalization. These issues are discussed in the context of controversy related to Florida's forensic mental health system, as well as issues related to the political process and funding of the state's mental health authority. 相似文献

Studies of human memory often generate data on the sequence and timing of recalled items, but scoring such data using conventional
methods is difficult or impossible. We describe a Python-based semiautomated system that greatly simplifies this task. This
software, called PyParse, can easily be used in conjunction with many common experiment authoring systems. Scored data is
output in a simple ASCII format and can be accessed with the programming language of choice, allowing for the identification
of features such as correct responses, prior-list intrusions, extra-list intrusions, and repetitions. 相似文献

This study investigates the relation between temperament and information processing in 7-month-old infants. Infant temperament was assessed on multiple dimensions, using mothers' ratings on the Infant Behavior Questionnaire (IBQ). Information processing was measured during a paired-comparison visual categorization task. Infants (N=50) were familiarized with five different pairs of visual stimuli from one category, followed by two test trials, each contrasting a novel familiar-category item with a novel out-of-category item (animals vs. vehicles). Drop-out rate in this task was within a normal range (21%). No differences in temperament were found between completers and non-completers, but high reactivity to novelty and low motor activity were positively correlated with the strength of infants' familiarization response. Group comparisons between infants scoring high and low on these two dimensions of temperament confirmed this general finding: infants high on distress to novelty and low on motor activity showed stronger familiarization responses. Furthermore, infants scoring low on motor activity showed a stronger categorization response than highly active infants. This study provides evidence that performance in a cognitive categorization task and dimensions of infant temperament are systematically related during the second half of the first year of life. Implications for cognitive research with infants of this age-range will be discussed. 相似文献
