One standard to rule them all?

It has been argued that an epistemically rational agent's evidence is subjectively mediated through some rational epistemic standards, and that there are incompatible but equally rational epistemic standards available to agents. This supports Permissiveness, the view according to which one or multiple fully rational agents are permitted to take distinct incompatible doxastic attitudes towards P (relative to a body of evidence). In this paper, I argue that the above claims entail the existence of a unique and more reliable epistemic standard. My strategy relies on Condorcet's Jury Theorem. This gives rise to an important problem for those who argue that epistemic standards are permissive, since the reliability criterion is incompatible with such a type of Permissiveness.     

Cornerstones: You’d better believe them

Crispin Wright??s ??Unified Strategy?? for addressing some familiar sceptical paradoxes exploits a subtle distinction between two different ways in which we can be related to a proposition: (full-blown) belief and (mere) acceptance. The importance of the distinction for his strategy stems from his conviction that we cannot acquire any kind of evidence, either empirical or a priori, for the ??cornerstones?? of our cognitive projects, i.e., for those basic presuppositions of our inquiries that we must be warranted to endorse if we are to claim warrant for any of the beliefs formed as a result of such inquiries: regarding the idea of a non-evidential warrant to believe a proposition as a kind of ??conceptual solecism??, he doesn??t set himself the task of showing that we are evidentially warranted to believe such presuppositions, but only that of showing that we are non-evidentially warranted to accept them. In the present paper, I argue that such choice involves a fatal departure from a basic principle governing doxastic commitment??a principle that requires that we regard cornerstones propositions as propositions we are rationally committed to believe, not just entitled to accept. I press the point by presenting the Acceptance Argument, a sceptical paradox whose consideration leads to the conclusion that the Unified Strategy is caught between the Scylla of incoherently invoking a rather dubious form of epistemic alchemy and the Charybdis of placing an unexpected and apparently ad hoc restriction on the doxastic commitments we undertake by believing the things we believe. My final suggestion is that the Unified Strategy might be spared this dilemma only by undergoing a rather radical revision??a revision that would require setting aside the distinction between belief and acceptance to re-conceptualise its goal unabashedly in terms of (non-evidentially) warranted belief.     

Temporary employees in Singapore: what drives them?

In this study the authors provide an empirical analysis of the job attitudes and behavior of temporary workers in Singapore, compiling and categorizing the various reasons individuals choose temporary jobs, in an effort to provide a clear and comprehensive understanding of why people choose this work arrangement. A profile of temporary employees showed that job attitudes are affected by the importance of the various reasons given for being a temporary worker. This exploratory study provides a foundation on which more complex relationships between these variables can be examined.     

How gender-expectancy affects the processing of “them”

How sensitive is pronoun processing to expectancies based on real-world knowledge and language usage? The current study links research on the integration of gender stereotypes and number-mismatch to explore this question. It focuses on the use of them to refer to antecedents of different levels of gender-expectancy (low–cyclist, high–mechanic, known–spokeswoman). In a rating task, them is considered increasingly unnatural with greater gender-expectancy. However, participants might not be able to differentiate high-expectancy and gender-known antecedents online because they initially search for plural antecedents (e.g., Sanford & Filik), and they make all-or-nothing gender inferences. An eye-tracking study reveals early differences in the processing of them with antecedents of high gender-expectancy compared with gender-known antecedents. This suggests that participants have rapid access to the expected gender of the antecedent and the level of that expectancy.     

Meta-insight: do people really know how others see them?

Although people can accurately guess how others see them, many studies have suggested that this may only be because people generally assume that others see them as they see themselves. These findings raise the question: In their everyday lives, do people understand the distinction between how they see their own personality and how others see their personality? We examined whether people make this distinction, or whether people possess what we call meta-insight. In 3 studies, we assessed meta-insight for a broad range of traits (e.g., Big Five, intelligent, funny) across several naturalistic social contexts (e.g., first impression, friends). Our findings suggest that people can make valid distinctions between how they see themselves and how others see them. Thus, people seem to have some genuine insight into their reputation and do not achieve meta-accuracy only by capitalizing on the fact that others see them similarly to how they see themselves.     

What are social groups? Their metaphysics and how to classify them

This paper presents a systematic approach for analyzing and explaining the nature of social groups. I argue against prominent views that attempt to unify all social groups or to divide them into simple typologies. Instead I argue that social groups are enormously diverse, but show how we can investigate their natures nonetheless. I analyze social groups from a bottom-up perspective, constructing profiles of the metaphysical features of groups of specific kinds. We can characterize any given kind of social group with four complementary profiles: its “construction” profile, its “extra essentials” profile, its “anchor” profile, and its “accident” profile. Together these provide a framework for understanding the nature of groups, help classify and categorize groups, and shed light on group agency.

     

Words: what are they, and do animals have them?

Since the word is not a well-defined entity like the sentence, one looks for findings that may help to clarify it. The effect of nonsense words on the young child's sorting of taxonomic versus thematic alternatives is said to be such a finding. A young child given, say, duck as a sample, goose and nest as alternatives, picks nest (thematic alternative), whereas the older child picks goose (taxonomic). However, if told the duck is called "ZLT" in Croatian, and asked to "find another ZLT", the young child shifts to goose. Markman and Hutchinson (1984) claim this demonstrates that young children know that words are "names of object categories" (and that this knowledge protects them against false hypotheses, facilitating their acquisition of words). In the present study, we applied the Markman et al. procedure to young "language-trained" chimpanzees. The animals were at an early stage of training, having used "words" solely in the function "X goes with Y", or "if shown X, get Y". Although these functions are notably weaker than "X is the name of a category", the animals showed a thematic-taxonomic shift, thus behaving like young children. The Markman-Hutchinson interpretation of the shift effect is unsatisfactory in two respects: (1) the shift effect can be explained without attributing any knowledge of what a word is to either creature, child or ape; more important (2), the interpretation does not address the main question: what is a "name" and what does a child think it is? We conclude with a discussion of what a word is, appealing to information retrieval on the one hand, and intention to refer on the other.     

Multiple cues for quantification in infancy: is number one of them?

A review and synthesis of the literature on quantification in infancy and early childhood is provided. In most current conceptualizations, early quantification is assumed to be number based. However, the extant literature provides no clear-cut evidence that infants use number to perform quantitative tasks. Instead, new research suggests that quantification is initially based on nonnumerical cues, such as area and contour length, whether or not a task involves discrete items. The authors discuss the implications of these findings with respect to early quantification and its relation to later numerical development.     

Neuromotor profiles: what are they and what can we learn from them?

Eye movements, alternating movements, rapid pointing movements, and various tremors were measured on patients with Parkinson's disease (n = 21), on Cree subjects exposed to methylmercury (n = 36), and on healthy control subjects (n = 30). Neuromotor profiles were created according to thirty characteristics extracted from test results of four subgroups matched for age and composed of six subjects each. Z scores were calculated with respect to the mean and standard deviation of the control group for each of the 30 characteristics. The subgroup with the lower methylmercury blood level had larger z scores than the control subgroup and with a few positive values above one standard deviation. The subgroup with the higher methylmercury blood level had several z scores above two standard deviations. Interestingly, the abnormal values for the subgroup with Parkinson's disease were mostly limited to static tremor recorded with no visual feedback and reached up to 5 standard deviations. These results indicate that neuromotor profiles can be used to summarize information extracted from different neuromotor tests and to differentiate neurological conditions.     

Tests improve memory – no matter if you feel good or bad while taking them

ABSTRACT

Based on studies demonstrating that testing promotes better long-term retention than restudying (i.e., the testing effect), testing has been recommended as a powerful tool to boost knowledge acquisition in educational settings. However, a factor ubiquitous in real-life learning contexts has been ignored to date: the learner's affective state. To examine whether the learner's affective state influences the testing effect, we conducted two experiments. We employed a standard testing-effect paradigm consisting of an initial study phase and a subsequent restudy/testing phase, and induced negative, neutral, or positive affective states either before participants initially studied short expository texts (Experiment 1) or before they restudied or were tested on them (Experiment 2). After one week, memory for the texts was tested. In both experiments, previously tested material was better remembered than previously restudied material. However, in none of the experiments, did the memory advantage of testing over restudying vary as a function of affect condition. Hence, the present results suggest that testing seems to benefit long-term retention independently of the learner's affective state.     

She's supporting them; who's supporting her? Preschool center-level social-emotional supports and teacher well-being

Preschool teachers across the country have been charged to prepare children socially and emotionally for kindergarten. Teachers working in preschool centers are supporting children's social and emotional learning (SEL) within a rich ecology of emotion and social relationships and the present study considers how the supports implemented for children's SEL at the center-level are associated with teachers' psychological health and workplace experiences. Hierarchical linear models were constructed using data from the Head Start Family and Child Experiences Survey 2009 cohort. Results indicate that although teachers work in individual classrooms, they share common perceptions at the center-level of their workplace climate, access to support, and, although to a lesser extent, experience commonalities in psychological health and job satisfaction. Furthermore, in centers that had implemented more supports for children's SEL (including access to mental health consultants, classroom curriculum, and training and resources for teachers) teachers were less depressed, more satisfied with their jobs, felt more supported in managing challenging behavior, and viewed the workplace climate of their center as more positive. Findings are discussed in light of the national efforts to increase and retain a high-quality early childhood workforce.     

The silent voices of research: What can we do to help them speak?1

The authors challenge the legitimacy of making commissioning decisions based solely upon the current outcome research for the psychological treatments. They argue that this outcome data does not represent the treatment needs of the patient who fails to complete a therapy. They call for a shift in the focus of research in order to right this oversight.     

Models of verbal working memory capacity: what does it take to make them work?

Theories of working memory (WM) capacity limits will be more useful when we know what aspects of performance are governed by the limits and what aspects are governed by other memory mechanisms. Whereas considerable progress has been made on models of WM capacity limits for visual arrays of separate objects, less progress has been made in understanding verbal materials, especially when words are mentally combined to form multiword units or chunks. Toward a more comprehensive theory of capacity limits, we examined models of forced-choice recognition of words within printed lists, using materials designed to produce multiword chunks in memory (e.g., leather brief case). Several simple models were tested against data from a variety of list lengths and potential chunk sizes, with test conditions that only imperfectly elicited the interword associations. According to the most successful model, participants retained about 3 chunks on average in a capacity-limited region of WM, with some chunks being only subsets of the presented associative information (e.g., leather brief case retained with leather as one chunk and brief case as another). The addition to the model of an activated long-term memory component unlimited in capacity was needed. A fixed-capacity limit appears critical to account for immediate verbal recognition and other forms of WM. We advance a model-based approach that allows capacity to be assessed despite other important processing contributions. Starting with a psychological-process model of WM capacity developed to understand visual arrays, we arrive at a more unified and complete model.     

Which social needs are important for subjective well-being? What happens to them with aging?

In this study the authors investigated how satisfaction levels of affection, behavioral confirmation, and status, as three human social needs, relate to age, physical loss, and subjective well-being. Results (N=883, aged 65 to 98 years) revealed that (a) affection was relatively high and status was relatively low in all age and loss groups; behavioral confirmation showed negative age and loss effects but was better predicted by loss; (b) the three needs relate differentially to indicators of subjective well-being: affection and behavioral confirmation relate positively to life satisfaction; status and behavioral confirmation relate positively to positive affect and negatively to negative affect. It is concluded that the need for behavioral confirmation is more difficult to satisfy with high physical loss, but none of the three social needs becomes less important with advancing age.     

Do worksite stress management programs attract the employees who need them and are they effective?

Employees who planned to attend a worksite stress management program (volunteers), those who planned not to attend (nonvolunteers), and those who had participated in worksite stress management training were assessed on the variables of work stressors, perceived stress, and organizational spontaneity (extrarole) behavior. Twelve hundred hospital employees were randomly selected from seven VA hospitals that had been offering a stress management program for at least 5 years. Participants received questionnaire packets in the mail and 461 (38%) of the employees responded. The results showed that volunteers reported significantly more perceived stress than the nonvolunteers. However, volunteers did not report greater frequency or intensity of work stressors. Also, respondents who had participated in past stress training reported less perceived stress than volunteers and significantly more organizational spontaneity behavior than respondents who had not participated in past stress training. These findings suggest that employees who plan to attend stress training have the greatest need and that the stress intervention reduces perceived stress levels and, possibly, affects work behavior.     

Individuals with intellectual and developmental disabilities: Do educators assign them a fully human status?

The present research investigates the humanity attributions to individuals with intellectual and developmental disabilities (IDD). In three studies, professional educators, who worked in day‐care or community centers, were examined. Humanity attributions were assessed using emotion‐based and trait‐based measures. As expected, individuals with IDD were denied a fully human status: they were perceived as having more non‐uniquely than uniquely human attributes. Furthermore, a lower human status was assigned to individuals with IDD in relation to educators. We also discovered that humanity attributions, but not attitudes, were related to approach/avoidance responses. Altogether, findings show the importance of considering humanity perceptions in the study of social relationships of individuals with IDD. Dehumanizing perceptions can explain the differential treatment these individuals face in various social settings.
