Our ability to actively maintain information in visual memory is strikingly limited. There is considerable debate about why this is so. As with many questions in psychology, the debate is framed dichotomously: Is visual working memory limited because it is supported by only a small handful of discrete “slots” into which visual representations are placed, or is it because there is an insufficient supply of a “resource” that is flexibly shared among visual representations? Here, we argue that this dichotomous framing obscures a set of at least eight underlying questions. Separately considering each question reveals a rich hypothesis space that will be useful for building a comprehensive model of visual working memory. The questions regard (1) an upper limit on the number of represented items, (2) the quantization of the memory commodity, (3) the relationship between how many items are stored and how well they are stored, (4) whether the number of stored items completely determines the fidelity of a representation (vs. fidelity being stochastic or variable), (5) the flexibility with which the memory commodity can be assigned or reassigned to items, (6) the format of the memory representation, (7) how working memories are formed, and (8) how memory representations are used to make responses in behavioral tasks. We reframe the debate in terms of these eight underlying questions, placing slot and resource models as poles in a more expansive theoretical space. 相似文献

The MMPI and MMPI-2 validity scales have long been accepted as standard tools in the assessment of feigned mental disorders
(FMD) based on their extensive empirical validation. Studies are now examining MMPI-2-RF with modified validity scales plus
the new Infrequent Somatic Responses Scale (FS) and the recently-adapted Response Bias Scale (RBS). The current investigation used a known-groups design to examine the
effectiveness of the MMPI-2-RF for differentiating FMD and feigned cognitive impairment (FCI) from patients with genuine disorders
for a large civil forensic sample. Criterion measures included the Structured Interview of Reported Symptoms-2 (SIRS-2) for
the FMD group, and below-chance performances on the Victoria Symptom Validity Test (VSVT) and the Test of Memory Malingering
(TOMM) for the FCI group. For FMD, both F-r and FP-r produced very large effect sizes (ds > 2.00). Moreover, the absence of severe elevations (≥80 T) on F-r proved effective at ruling-out most FMD. For the current
study, a FP-r cut score ≥90 T for FMD produced virtually no false-positives (0.01) and only a moderate level of false-alarms. As predicted
by its detection strategies, most MMPI-2-RF validity scales have limited effectiveness with the FCI group. However, FBS-r
and RBS may be useful in conjunction with other clinical data for ruling out FCI for genuine neuropsychological consults.
An entirely separate concern is whether certain diagnostic groups, such as major depression, will have marked elevations on
MMPI-2-RF scales thereby increasing the likelihood of false-positives. On this point, FP-r performed exceptionally well with unelevated scores (Ms < 55 T) consistently across diagnostic categories. 相似文献

In the aftermath of several school shooting incidents in recent years, students’ perceptions of unsafe schools has been a
major concern for parents, teachers, school officials, school practitioners, and policy-makers. Using Bronfenbrenner’s ecological
systems framework, we examined the micro-, meso-, and exosystem level factors associated with perceptions of unsafe school
environments in a nationally representative sample of 10- to 15-year-old youth in the United States. We found that for the
socio-demographic characteristics, students who were older, male, and poor had increased risks of perceiving higher levels
of unsafe school environments. Within the microsystem of the family, our results indicate that parent-youth discussions of
school activities/events decreased the risk of students perceiving unsafe schools. All of the school environment variables—ease
of making friends, teachers’ involvement, observed weapon carrying, and school rule enforcement—were related in the expected
direction to students’ perceiving their schools as unsafe. At the mesosystem level, findings from our study demonstrate that
variables measuring parental school involvement were unrelated to perceptions of school safety. Finally, at the exosystem
level, we found that students’ perceptions of residing in a safer neighborhood and residence in a non-central city metropolitan
area, compared with a central city, decreased the odds of perceiving school environments as unsafe. School policy and practice
implications are discussed. 相似文献

The goal of the study was to examine the dimensionality of the Career Decision Self-Efficacy Scale Short Form (CDSES-SF, Betz et al. 1996). Integrating several previous findings from different cultures, we found that the bifactor structure of the CDSES-SF on a Hungarian sample of 649 respondents showed the best model fit. This structure includes a general CDSE factor covering 15 items and the original five specific factors (self-appraisal, occupational information, goal selection, planning, and problem solving) covering three items each. This short form of CDSES shows an acceptable model fit and appropriate reliability in terms of the Cronbach’s alpha and omega values. Regarding career decision self-efficacy, a large proportion of variance was explained by the general factor and to a smaller extent by the specific factors. These results can be considered as a first step in resolving the paradox of the dimensionality of CDSES-SF. 相似文献

The study examines how demographics, other forms of compulsive behaviour and personality are related to the buying frequency and compulsiveness in lottery tickets and scratch‐cards. An integrative framework is developed and tested in a sample of respondents. Results indicated that the buying compulsivenesses in lottery tickets and scratch‐cards have the same correlates. The buying compulsivenesses in both lottery tickets and scratch‐cards were found to be positively related to cigarette consumption and the extraversion dimension of personality and negatively related to the agreeableness and intellect dimensions of personality.

Confucianism defined benevolence with “feelings” and “love.” “Feelings” in Confucianism can be mainly divided into three categories:
feelings in general (seven kinds of feelings), love for one’s relatives, and compassion (Four Commencements). The seven kinds
of feeling in which people respond to things can be summarized as “likes and dislikes.” The mind responds to things through
feelings; based on the mind of benevolence and righteousness or feelings of compassion, the expression of feelings can conform
to the principle of the mean and reach the integration of self and others, and of self and external things. The “relations
between the seven kinds of feelings and the Four Commencements,” however, was not developed into a theoretical idea in Confucianism.
After Confucius, the relationship between the universality of natural sympathies and the gradation of love for relatives gradually
became an important subject in Confucian ideas of benevolence and love. By “refuting Yang Zhu and Mozi,” Mencius systematically
expounded on this issue. Love had two ends: self-love and natural sympathies, between which existed the love for relatives.
These two ends were not the two extremes of Yang’s self-interest and Mozi’s universal love. Love for relatives not only implied
a gradation, but also contained universality and transcendence that came from self-love. Love for relatives, natural sympathies
and self-love had a kind of tension and connectivity between two dynamic ends. The Confucian idea of benevolence and love
hence demonstrated differences and interconnectivity. An accurate understanding of such “feelings” and “love” is important
for us to grasp Confucian thoughts on benevolence and its realization. 相似文献

The study examined whether relationships with extended kin were related to higher levels of mental health and academic functioning among college students. Specifically, the study tested whether perceived emotional support from extended (non-nuclear) family was related to self-esteem, psychological distress, and academic efficacy and dedication above and beyond relationships with one’s primary caregivers, and whether these associations varied by class year in college. The sample consisted of 530 students (average age = 20.82), at a public, four-year university. The results revealed that freshmen and seniors who reported high levels of positive relationships with their extended kin also reported higher levels of academic-efficacy and dedication, as well as lower levels of psychological distress. However, the relation between kin emotional support and these outcomes were not significant for sophomores and juniors. There was also a significant association between kinship support and self-esteem for participants in all four class levels. The study underscores the need to examine extended social support systems among college students, above and beyond those maintained with primary caregivers, as well as the dynamic nature of family support during young adulthood. 相似文献

What are moral principles? In particular, what are moral principles of the sort that (if they exist) ground moral obligations or—at the very least—particular moral truths? I argue that we can fruitfully conceive of such principles as real, irreducibly dispositional properties of individual persons (agents and patients) that are responsible for and thereby explain the moral properties of (e.g.) agents and actions. Such moral dispositions (or moral powers) are apt to be the metaphysical grounds of moral obligations and of particular truths about what is morally permissible, impermissible, etc. Moreover, they can do other things that moral principles are supposed to do: explain the phenomena “falling within their scope,” support counterfactuals, and ground moral necessities, “necessary connections” between obligating reasons and obligations. And they are apt to be the truthmakers for moral laws, or “lawlike” moral generalizations. 相似文献

Prior research has shown that people can learn many nouns (i.e., word–object mappings) from a short series of ambiguous situations containing multiple words and objects. For successful cross‐situational learning, people must approximately track which words and referents co‐occur most frequently. This study investigates the effects of allowing some word‐referent pairs to appear more frequently than others, as is true in real‐world learning environments. Surprisingly, high‐frequency pairs are not always learned better, but can also boost learning of other pairs. Using a recent associative model (Kachergis, Yu, & Shiffrin, 2012), we explain how mixing pairs of different frequencies can bootstrap late learning of the low‐frequency pairs based on early learning of higher frequency pairs. We also manipulate contextual diversity, the number of pairs a given pair appears with across training, since it is naturalistically confounded with frequency. The associative model has competing familiarity and uncertainty biases, and their interaction is able to capture the individual and combined effects of frequency and contextual diversity on human learning. Two other recent word‐learning models do not account for the behavioral findings. 相似文献

This paper describes an attempt at forming and conducting a unique single-gender psychotherapy group with severely disturbed female adolescents on a long-term, psychotherapeutically oriented co-ed inpatient unit. The focus of this group was assisting the female patients in negotiating the tasks and conflicts specific to their gender and developmental stage. The therapeutic approach and the role of female coleaders are described, emphasizing particular modifications made to meet the needs of this group. Clinical examples are offered to high-light salient group themes of identity formation and separation and individuation. Finally, group therapeutic factors specifically enhanced by single gender membership are discussed and observations regarding the group/milieu interface are explored. 相似文献
