Word-list-learning performance in younger and older adults: intra-individual performance variability and false memory

We investigated the word-list-learning performance of younger and older adults over 4 consecutive days at different times of day to study age-related differences in consistency of performance over time and the influence of circadian variation on performance. Eighteen younger (M age, 23.4 years) and 18 older (M age, 73.3 years) men and women participated. The start time of testing alternated between morning and early evening across the 4 days of testing. On each test day, participants learned a different list of 15 unrelated words over four learning trials. As expected, younger adults performed better than older adults on immediate recall, delayed recall, and recognition. Contrary to our expectations, time of day did not significantly influence recall or recognition performance in either the older or younger adults. Older adults did show a greater incidence of false memory (i.e., previously learned list intrusions in free recall and false alarms in recognition) than younger adults. Older adults also exhibited greater intra-individual performance variability on the measures of false memory across test days. This variability was not related to circadian variation. False memory and variability of performance have both been linked to frontal systems dysfunction. The findings presented here are consistent with the notion that changes in cognition with aging in part reflect age-related decline in frontal lobe function.     

Physicalism and sparse ontology

A major stumbling block for non-reductive physicalism is Kim’s disjunctive property objection. In this paper I bring certain issues in sparse ontology to bear on the objection, in particular the theses of priority monism and priority pluralism. Priority pluralism (or something close to it, anyway) is a common ontological background assumption, so in the first part of the paper I consider whether the disjunctive property objection applies with equal force to non-reductive physicalism on the assumption that priority monism is instead true. I ultimately conclude that non-reductive physicalism still faces a comparable problem. In the second part, I argue, surprisingly enough, that what I call ‘fine-grained reductionism’, a particular version of which Kim proposes as an alternative to non-reductive physicalism, may work better in the monist framework than the pluralist one. I conclude that issues in sparse ontology, therefore, are more relevant to the debate about physicalism than one may have thought.

The modal status of materialism

Materialism, as traditionally conceived, has a contingent side and a necessary side. The necessity of materialism is reflected by the metaphysics of realization, while its contingency is a matter of accepting the possibility of Cartesian worlds, worlds in which our minds are roughly as Descartes describes them. In this paper we argue that the necessity and the contingency of materialism are in conflict. In particular, we claim that if mental properties are realized by physical properties in the actual world, Cartesian worlds are impossible.

Which training method works best? A randomized controlled trial comparing three methods of training clinicians in dialectical behavior therapy skills

This study evaluated the efficacy of three methods of training community mental health providers (N = 150) in Dialectical Behavior Therapy skills, including a written treatment manual; an interactive, multimedia online training (OLT); and a two-day instructor-led training workshop (ILT). A hybrid design was utilized that incorporated aspects of efficacy and effectiveness trials. Assessments were completed at baseline, post-training, and 30- and 90-days following training. The results indicate that learner satisfaction with the training was highest in OLT and ILT, and both resulted in significantly higher satisfaction ratings than the manual. OLT outperformed ILT and the manual in increasing knowledge of the treatment, whereas ILT and the manual did not differ. All three training methods resulted in comparable increases in clinicians' ability to apply course content in clinical simulations. Overall, the results provide strong support for the efficacy of technology-based OLT methods in disseminating knowledge of empirically supported treatments to community mental health providers, suggesting that OLT may be a high-quality, easily accessible, and affordable addition to traditional training methods.     

Associations between emotional avoidance,anxiety sensitivity,and reactions to an observational fear challenge procedure

Research has shown that emotional avoidance and anxiety sensitivity are associated with more self-reported fear and distress in response to laboratory fear challenge procedures. The present study aimed to expand upon this work and examined how emotional avoidance and anxiety sensitivity are related to emotional and physiological responses to an observational fear challenge procedure. To accomplish this aim, a carefully screened, non-clinical sample (N = 43) was administered the Acceptance and Action Questionnaire (AAQ), a measure of emotional avoidance, and the Anxiety Sensitivity Index (ASI). Participants then engaged in an observational fear challenge paradigm. During the fear challenge, participants watched mock panic attacks while emotional (e.g., fear and panic) and skin conductance levels were assessed. Consistent with expectation, emotional avoidance and anxiety sensitivity were positively associated with more self-reported fear and more severe panic symptoms to the challenge procedure. However, anxiety sensitivity was more highly associated with self-reported fear and panic symptoms in response to the challenge procedure than emotional avoidance. Emotional avoidance and anxiety sensitivity were not associated with levels of physiological arousal to the observational fear challenge procedure. Discussion focuses on the interplay between emotional avoidance, anxiety sensitivity, and the development of vicarious fear responses and how these constructs may contribute to the pathogenesis of anxiety disorders.     

Dispositional Affectivity and Work-Related Outcomes: A Meta-Analysis

This study meta-analytically reviews the influence of individuals' dispositional negative affectivity (NA) and positive affectivity (PA) on a broad range of work-related outcomes grouped into 3 categories: (a) work attitudes; (b) workplace experiences; and (c) work behavior. Across cumulative studies, it was found that NA and PA demonstrated significant effects on most of these outcomes. Moreover, we found some interesting differences in NA's and PA's relationships with work outcomes. Specifically, while NA had more influence on variables pertinent to work stressors (e.g., role problems), PA demonstrated a stronger effect on variables related to positive job and organizational context (e.g., job autonomy, procedural justice). Implications for theory advancement and future research in this area are discussed.     

Activating event knowledge

An increasing number of results in sentence and discourse processing demonstrate that comprehension relies on rich pragmatic knowledge about real-world events, and that incoming words incrementally activate such knowledge. If so, then even outside of any larger context, nouns should activate knowledge of the generalized events that they denote or typically play a role in. We used short stimulus onset asynchrony priming to demonstrate that (1) event nouns prime people (sale-shopper) and objects (trip-luggage) commonly found at those events; (2) location nouns prime people/animals (hospital-doctor) and objects (barn-hay) commonly found at those locations; and (3) instrument nouns prime things on which those instruments are commonly used (key-door), but not the types of people who tend to use them (hose-gardener). The priming effects are not due to normative word association. On our account, facilitation results from event knowledge relating primes and targets. This has much in common with computational models like LSA or BEAGLE in which one word primes another if they frequently occur in similar contexts. LSA predicts priming for all six experiments, whereas BEAGLE correctly predicted that priming should not occur for the instrument-people relation but should occur for the other five. We conclude that event-based relations are encoded in semantic memory and computed as part of word meaning, and have a strong influence on language comprehension.     

The Body of Christ has AIDS: The Catholic Church Responding Faithfully to HIV and AIDS in Papua New Guinea

Using the example of the Catholic Church in Papua New Guinea (PNG), I detail how, through praxis, it has brought to life a living theology of HIV and AIDS. In this way, the Catholic Church in PNG is responding faithfully to the epidemic. As a Christian country with a generalised HIV epidemic, where the body of an individual is reconstituted through the liturgical practices of baptism and Eucharist, theologically, in PNG the body of Christ has AIDS. In order to examine the ways in which the Catholic Church in PNG has responded faithfully to the Christian body with AIDS, I do so in relation to the three theological virtues of faith, hope and love.

Re-conceptualizing the Factor Structure of the Brief Multidimensional Measure of Religiousness/Spirituality

Rationale This study attempted to differentiate statistically the spiritual and religious factors of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS), which was developed based on theoretical conceptualizations that have yet to be adequately empirically validated in a population with significant health disorders. Participants One hundred sixty-four individuals with heterogeneous medical conditions [i.e., brain injury, spinal cord injury (SCI), cancer, stroke, primary care conditions]. Methods Participants completed the BMMRS as part of a pilot study on spirituality, religion, and physical and mental health. Results A principal components factor analysis with varimax rotation and Kaiser normalization identified a six-factor solution (opposed to the expected 8-factor solution) accounting for 60% of the variance in scores, labeled as: (1) Positive Spiritual Experience; (2) Negative Spiritual Experience; (3) Forgiveness; (4) Religious Practices; (5) Positive Congregational Support; and (6) Negative Congregational Support. Conclusions The results suggest the BMMRS assesses distinct positive and negative aspects of religiousness and spirituality that may be best conceptualized in a psychoneuroimmunological context as measuring: (a) Spiritual Experiences (i.e., emotional experience of feeling connected with a higher power/the universe); (b) Religious Practices (i.e., prayer, rituals, service attendance); (c) Congregational Support; and (d) Forgiveness (i.e., a specific coping strategy that can be conceptualized as religious or non-religious in context).     

Associations between Maternal Physical Discipline and Peer Victimization among Hong Kong Chinese Children: The Moderating Role of Child Aggression

This study examines the relation between maternal physical discipline and victimization by peers, as moderated by child aggression. The sample consisted of 211 Hong Kong Chinese children (98 boys, 113 girls; average age of 11.9). Physical discipline was assessed with a questionnaire completed by mothers, and victimization by peers and aggression were measured using a peer nomination inventory. Latent variable models revealed a moderately strong link between children’s experiences with maternal physical discipline and peer victimization, but this effect held only for children who were also high on aggression. These results highlight the interplay between harsh home environments and child aggression and their contributions to the child’s adjustment in the peer group.
