Threat Vigilance in Child Witnesses of Domestic Violence: A Pilot Study Utilizing the Ambiguous Situations Paradigm

Research has found that children exposed to family violence exhibit higher rates of maladjustment. We review relevant literature on family violence, marital conflict, and cognitive factors implicated in child behaviour problems. A bias toward perceiving threat in ambiguous contexts has been identified as one factor mediating both aggressive and anxious behaviour disorders. We conducted a study utilizing the ambiguous situations paradigm to assess whether children exposed to violent spousal conflict were more likely than children not exposed to violence (divided into children with an externalizing behaviour disorder and non-clinic children) to perceive threat in two classes of ambiguous situations: Peer and Inter-Parental. The results indicated that children exposed to violent spousal conflict perceived more threat in parental situations than either of the other two groups. A number of considerations were taken into account given the exploratory nature of the study, particularly sample limitations. We conclude with suggestions for improvements to the research design and the further relevance of exploring cognitive factors involved in the adjustment of children from backgrounds of violence.     

Infants and toddlers discriminate amount: are they measuring?

Four experiments that show an early ability to encode and retain information about extent are presented. We found that infants discriminate between the heights of dowels in a habituation task. We also found that toddlers discriminate between heights on a choice task in which a target dowel is presented and removed and they then choose between the target and a foil. Until 4 years of age, however, discrimination occurs only in the presence of a perceptually salient standard. Adults do not require a perceptually present standard; they can assess extent across temporal or spatial gaps by imposing a standard (measure). The present findings indicate that infants and toddlers do not possess an adult ability to establish extent, but that they do possess a skill that provides a start point for this important intellectual achievement.     

Examining predictors and outcomes of a career calling among undergraduate students

The current study examined predictors and outcomes of a career calling among 292 undergraduate students at two time points over a three-month period. Using structural equation modeling, a model was tested that examined the extent to which calling, life meaning, the search for life meaning, vocational clarity, and personal growth at Time 1 would predict these same variables at Time 2. Results showed that calling was a significant predictor of personal growth and life meaning and that life meaning, the search for life meaning, and vocational self-clarity significantly predicted the presence of a calling. Although findings demonstrating calling as a predictor variable are consistent with previous research, these results also demonstrate the potential reciprocal relation of calling to proximal work and well-being variables over time. Implications and future research directions are discussed.     

Examining Moderators of Signature Strengths Use and Well-being: Calling and Signature Strengths Level

This study examined the relation between signature strengths use and satisfaction with a sample of diverse undergraduate students. We measured strengths use and satisfaction in both the life and academic domains and identified two possible moderators of this relation: the level of one’s signature strengths and the presence of calling. Results revealed a three way interaction between signature strengths use, signature strengths level, and calling in the prediction of life satisfaction and a two way interaction between signature strengths use and calling in the prediction of academic satisfaction. Contrary to our hypotheses, people low in calling and high in signature strengths level showed the strongest relation between signature strengths use and life satisfaction. For the academic domain, participants low in calling showed the strongest relation between strengths use and academic satisfaction but those high in calling still benefited from using their strengths. Implications for future research and limitations of the study are discussed.     

Calling and career adaptability among undergraduate students

The present study examined the relation of calling and career adaptability with a sample of 330 undergraduate students. The presence of a calling weakly to moderately correlated with the four components of adaptability — concern, control, curiosity, and confidence. A moderated, multiple mediation model was used to test the potential mediating effects of the four components of career adaptability on career decision self-efficacy (CDSE) and how these relations differed according to strengths use. Using bootstrapping techniques, concern and confidence were found to be significant mediators in the calling–CDSE relation. Additionally, strengths use was found to moderate the relation between curiosity and CDSE, with curiosity being a significant mediator at high levels of strengths use. After including the mediators in the model, the relation of calling to CDSE was weakened, but still significant, indicating partial mediation. These results suggest that calling relates to greater levels of CDSE in part because of increased concern, curiosity (when strengths use is high), and confidence. Directions for future research are discussed.     

Working memory and spatial judgments: Cognitive load increases the central tendency bias

Previous work demonstrates that memory for simple stimuli can be biased by information about the distribution of which the stimulus is a member. Specifically, people underestimate values greater than the distribution’s average and overestimate values smaller than the average. This is referred to as the central tendency bias. This bias has been explained as an optimal use of both noisy sensory information and category information. In largely separate literature, cognitive load (CL) experiments attempt to manipulate the available working memory of participants in order to observe the effect on choice or judgments. In two experiments, we demonstrate that participants under high cognitive load exhibit a stronger central tendency bias than when under a low cognitive load. Although not anticipated at the outset, we also find that judgments exhibit an anchoring bias not described previously.     

An ERP investigation of regional and foreign accent processing

This study used event-related potentials (ERPs) to examine whether we employ the same normalisation mechanisms when processing words spoken with a regional accent or foreign accent. Our results showed that the Phonological Mapping Negativity (PMN) following the onset of the final word of sentences spoken with an unfamiliar regional accent was greater than for those produced in the listener’s own accent, whilst PMN for foreign accented speech was reduced. Foreign accents also resulted in a reduction in N400 amplitude when compared to both unfamiliar regional accents and the listener’s own accent, with no significant difference found between the N400 of the regional and home accents. These results suggest that regional accent related variations are normalised at the earliest stages of spoken word recognition, requiring less top-down lexical intervention than foreign accents.     

Calling and Life Satisfaction Among Undergraduate Students: Investigating Mediators and Moderators

The present study examined the relation of calling and life satisfaction among a diverse group of undergraduate students. In line with previous research, the presence of a calling weakly correlated with life satisfaction and moderately correlated with meaning in life. Three potential moderators of the calling-life satisfaction relation were tested: religiousness, living one??s calling, and core self-evaluations. The relation of calling and life satisfaction was not different based on levels of religiousness or experiences of living one??s calling. However, the relation of calling to life satisfaction was stronger for students with low core self-evaluations. Additionally, using a multiple mediation model, academic satisfaction and life meaning were found to fully mediate the calling-life satisfaction relation. Participants more likely to view their career as a calling were more satisfied in life because of attaining greater life meaning and satisfaction within the academic domain. Implications for future research and practice are discussed.     

Maimon’s Theory of Differentials As The Elements of Intuitions

Abstract

Maimon’s theory of the differential has proved to be a rather enigmatic aspect of his philosophy. By drawing upon mathematical developments that had occurred earlier in the century and that, by virtue of the arguments presented in the Essay and comments elsewhere in his writing, I suggest Maimon would have been aware of, what I propose to offer in this paper is a study of the differential and the role that it plays in the Essay on Transcendental Philosophy (1790). In order to do so, this paper focuses upon Maimon’s criticism of the role played by mathematics in Kant’s philosophy, to which Maimon offers a Leibnizian solution based on the infinitesimal calculus. The main difficulties that Maimon has with Kant’s system, the second of which will be the focus of this paper, include the presumption of the existence of synthetic a priori judgments, i.e. the question quid facti, and the question of whether the fact of our use of a priori concepts in experience is justified, i.e. the question quid juris. Maimon deploys mathematics, specifically arithmetic, against Kant to show how it is possible to understand objects as having been constituted by the very relations between them, and he proposes an alternative solution to the question quid juris, which relies on the concept of the differential. However, despite these arguments, Maimon remains sceptical with respect to the question quid facti.     

Possible Environmental Causes of Stages in Moral Reasoning

Both children (6-, 10-, and 14-year-olds) and their mothers were interviewed. The children's responses to moral dilemmas were classified into Kohlberg's three main categories—preconventional, conventional, and postconventional. The mothers were presented with a variety of hypothetical situations—e.g., they had just found out that their child had stolen something, and were asked to tell what they would say or do to their child in each situation. The mothers' hypothetical responses to such situations were divided into either the preconventional, conventional, or postconventional category depending on the level or moral reasoning such responses would imply to their children. The results indicated that as the age of the children increased, both the level of moral reasoning used by the children and the level of moral reasoning implied by the mothers' treatment of the children increased. Even with age partialed out, there was a significant positive relationship between the mothers' implied level of moral reasoning and the children's level of moral reasoning. Thus, although causality cannot be established, the results indicate that there is at least the possibility that environmental changes—i.e., changes in the way the mother treats the child—may be responsible for the appearance of stages in the child's development of moral reasoning.
