Prosocial behaviour mediates the relation between empathy and aggression in primary school children

ABSTRACT

The negative association between empathy and aggression has been widely investigated in the literature. However, the role of potential mediators and the extent to which their effects are gender-specific have been given considerably less attention. The present cross-sectional study was therefore aimed at examining the direct and indirect relations between empathy (differentiated into perspective taking and empathic concern), prosocial behaviour and aggression in a sample of 240 primary school children between 8 and 12 years of age. The results showed that perspective taking and empathic concern had indirect (rather than direct) negative effects on aggression by enhancing prosocial behaviour. These indirect paths applied equally well to boys and girls, although significant gender differences were observed in empathic concern, prosocial behaviour and aggression. Possible explanations and differences with previous studies are discussed.     

Enabling Action: Reflections upon Inclusive Participatory Research on Health with Women with Disabilities in the Philippines

People with disabilities experience health disparities arising from social, environmental, and system-level factors. Evidence from a range of settings suggests women with disabilities have reduced access to health information and experience barriers to screening, prevention, and care services. This results in greater unmet health needs, particularly in relation to sexual and reproductive health. Women with disabilities are also more likely to experience physical and sexual violence than women without disabilities, further undermining their health. Community-based participatory research (CBPR) can generate knowledge and underpin action to address such health disparities and promote health equity. However, the potential and challenges of disability inclusion in CBPR, particularly in contexts of poverty and structural inequality such as those found in low- and middle-income countries, are not well documented. In this paper, we reflect on our experience of implementing and evaluating W-DARE, a three-year program of disability-inclusive CBPR aiming to increase access to sexual and reproductive health and violence-response services for women with disabilities in the Philippines. We discuss strategies for increasing disability inclusion in research and use a framework of reflexive solidarity to consider the uneven distribution of the benefits, costs, and responsibilities for action arising from the W-DARE program.     

Colorblind and multicultural diversity strategies create identity management pressure

Colorblind and multicultural diversity strategies may create identity management pressure, leading minorities to assert or distance from their racial identity. In two experiments (N = 307, 279), Asian and Asian American participants in the United States completed racial identification measures, contemplated employment at a company expressing a multicultural, colorblind, or control strategy, and completed measures assessing ingroup similarity and comfort in the company. In the colorblind condition, participants who were strongly identified with their racial ingroup downplayed similarity to the ingroup and expressed less comfort relative to multicultural and control conditions. Participants who were weakly identified reported more similarity (but inconsistently) and more comfort in the colorblind relative to multicultural and control conditions. Thus, diversity strategies convey different meanings to strongly and weakly identified Asian individuals, with the former responding to colorblindness with identity distancing and the latter with identity assertion. Multiculturalism does not alter the typical pattern expected, with strongly identified asserting their identity more than weakly identified.     

An O(n log n)-Space Decision Procedure for the Relevance Logic B+

In previous work we gave a new proof-theoretical method for establishing upper-bounds on the space complexity of the provability problem of modal and other propositional non-classical logics. Here we extend and refine these results to give an O(n log n)-space decision procedure for the basic positive relevance logic B⁺. We compute this upper-bound by first giving a sound and complete, cut-free, labelled sequent system for B⁺, and then establishing bounds on the application of the rules of this system.     

Anxiety, perceptual and motor skills in an underwater environment

This research has analyzed the perceptual and motor skills in an underwater environment at 30 m of 24 subjects differing in diving experience. The State-Trait Anxiety Inventory, Form X-1, was administered to evaluate possible changes in anxiety associated with hyperbaric conditions during the perceptual and motor task. Analysis indicates that in comparison with experienced divers, less experienced divers showed a performance decrement. No changes in anxiety were observed.     

Judgmental relativism as a validity threat to standardized psychiatric rating scales

Judgemental relativism is a threat to the replicability and validity of measures of client behavior from direct rating scales whenever raters are exposed to different levels of client functioning since the internal standards, or anchor points, used to judge dimensional continua may vary on the basis of prior experience. Traditional interrater reliability indexes fail to identify such effects. The influence of judgmental relativism on summated ratings from the Nurses Observational Scale for Inpatient Evaluation (NOSIE-30) for 1040 adult mentally ill clients was examined with clinical staff raters from 24 treatment units in which the Time-Sample Behavioral Checklist (TSBC) provided full-week objective measures of actual client functioning via hourly direct observational coding (DOC). Regression analyses found that the same level of objective performance received higher or lower ratings across treatment units dependent on the raters'exposure to client groups that differed in level of functioning. Analyses of rating errors found that clients with better levels of functioning relative to others within treatment units were rated even higher than performance warranted. The operation of halo and contrast effects is explored and guidelines are provided for determining when judgmental relativism may produce or nullify significant differences. DOC assessments should be used instead of retrospective ratings to support most decisions in residential settings. Specific recommendations for the application of rating scales and improving data quality are provided.This study was the basis of a master's thesis at the University of Houston by Betty E. Rich under the direction of Gordon L. Paul and Marco J. Mariotto. Richard M. Rozelle, to whom appreciation is expressed for helpful comments, served on the examination committee.

Multiple mechanisms for recency with vowels and consonants

Three experiments were conducted to test the hypothesis that the difference in recency effect between vowel-contrasting and stop-contrasting lists of syllables in immediate ordered recall can be explained by item discriminability and regular short-term memory mechanisms, without any recourse to echoic memory or precategorical acoustic storage (PAS). In Experiment 1, the short-term memory mechanisms were manipulated by reducing amount of output interference and length of retention interval. The partial-report technique was used. The most important finding was the usual final-position recency effect (difference in recall between the fifth and sixth serial positions) for the vowel lists but not for the stop lists, regardless of the type of report. Thus the PAS theory could not be rejected. In Experiments 2 and 3, the last item was differentiated from the other items of the list, either by lengthening the interstimulus interval between the last and the next-to-last (Experiment 2) or by increasing the intensity of the last item (Experiment 3). In both cases, an increase of the final-position recency effect was found even for stop lists. Since a drop in recall errors was also obtained for the fourth item when its intensity was increased (von Restorff effect), this final-position recency effect for stop lists is likely to be due to item discriminability, and not to echoic memory for the last item. Item discriminability appeared to be the critical factor.     

Recall of mental sleep experience with or without prior verbalization.

We investigated whether verbalization of contents of mental sleep experience (MSE), just after awakening provoked during rapid eye movement (REM) sleep, facilitates subsequent recall in the morning. Twelve subjects were awakened four times in each of two experimental nights and alternately asked to recall, with or without concurrent verbalization, MSE contents preceding the awakening. In the morning, the subjects were asked to report MSEs both verbalized and nonverbalized during the night. If subjects were unable to provide a spontaneous morning report, they were prompted using a probe, which was the title given by the subjects to each MSE at the end of its verbalization or covert recall at night. Frequencies of spontaneous reports were high, regardless of whether MSEs had been previously verbalized or not. The proportions of spontaneous and probed reports were similar for verbalized and nonverbalized MSEs, but spontaneous morning reports were longer than probed ones, regardless of their previous verbalization. Spontaneous and probed morning reports corresponding to night reports shared similar linguistic structures (i.e., length of sentences and proportions of waking-related utterances, which are indicative of difficulty of retrieval for MSE contents) and had similar percentages of contents common to night and morning reports. These findings support the hypothesis that verbalization does not directly influence the further accessibility of MSE contents.     

Characterizations of Negative Definability in Modal Logic

Negative definability ([18]) is an alternative way of defining classes of Kripke frames via a modal language, one that enables us, for instance, to define the class of irreflexive frames. Besides a list of closure conditions for negatively definable classes, the paper contains two main theorems. First, a characterization is given of negatively definable classes of (rooted) finite transitive Kripke frames and of such classes defined using both traditional (positive) and negative definitions. Second, we characterize the negatively definable classes of rooted general frames.
