A Gabbay-Rule Free Axiomatization of T×W Validity

The semantical structures called T×W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, _O, which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator . However, these structures are also suitable for interpreting an extended language, _SO, containing a further possibility operator ^s which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history simultaneity operator. In the present paper we provide an infinite set of axioms in _SO, which is shown to be strongly complete forT ×W-validity. Von Kutschera (1997) contains a finite axiomatization of T×W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions.     

Temporal integration and segregation of brief visual stimuli: Patterns of correlation in time

Two brief sequential displays separated by a brief interstimulus interval (ISI) are often perceived as a temporally integrated unitary configuration. The probability of temporal integration can be decreased by increasing the ISI or (counterintuitively) by increasing stimulus duration. We tested three hypotheses of the relative contributions of stimulus duration and ISI to the breakdown of temporal integration (the storage, processing, and temporal correlation hypotheses). In the first of two experiments, stimulus duration and ISI were varied factorially, and estimates of temporal integration were obtained with a form-part integration task. The second experiment was a replication of the first at two levels of stimulus intensity. The outcomes were inconsistent with the storage and processing options, but confirmed predictions from the temporal correlation hypothesis. Whether two sequential stimuli are perceived as temporally integrated or disjoint depends not on the availability of visible persistence, but on the emergence of a neural code that is based on the temporal correlation between the two visual responses.     

The settler colonial roots and neoliberal afterlife of Problem Behavior Theory

Problem Behavior Theory (PBT) is an influential psychosocial theory that has shaped—and continues to shape—much research on adolescent development in the United States and abroad. It is the product of over a half-century of research conducted by psychologists-cum-behavioral scientists Lee and Richard Jessor. This article engages two striking features of the history of PBT. First, it tracks how, and to what effect, a theory elaborated to explain the so-called “deviant behavior” of a group of Native Americans was extended to explain the “problem behavior” of white, middle-class, settler youth, before coming to circulate as a universal theory of adolescent behavior. Second, it explores how a theory that was meant to explain individual behaviors by connecting them to their larger social contexts came to be embraced by researchers who have been criticized for doing precisely the opposite. To do so, this article draws from Indigenous and Settler Colonial Studies scholarship and sheds light on how the logics of settler colonialism and neoliberalism have participated in the coproduction of PBT and its reception.     

Critical stages in mental development: Childhood breath holding spells (BHS)

The authors present the first part of a study on children with BHS (Breath Holding Spells) syndrome. These children were chosen in order to examine a “pathological” situation in infancy that was as close as possible to a “normal” one, and in which obvious somatic symptoms were associated with emotional states. Children with BHSS are not considered to have serious psychological disturbances, even if they are constantly referred to as intolerant of separation, stubborn, oppositional, or easy to temper tantrum. A reduced ability to tolerate frustration is evident in these children both from the patients' history and clinical observation. Parents usually relate BHS to situations in which the child is denied something or gets scolded. The children were observed during three sessions, both with and without the mother, according to a grid used at our Center. Patients are presented to illustrate certain recurrent features in play and interaction with mother. The data suggest that these children stagnate in an area of incomplete mental representation; something makes them oscillate between two states; in one of them, the mental representation of the object and of the bond with it is possible; in the other, the mental representation of the separation, which entails the recognition of the object, is felt as dangerous.     

The impact of prestimulus EEG frequency on auditory evoked potentials during sleep onset.

Auditory evoked potentials were recorded during wakefulness, Stage 1, and Stage 2 non-REM sleep using a three-tone auditory oddball paradigm. Stage 1 sleep was divided into trials preceded by alpha and those preceded by theta. A negative wave peaking at about 100 ms, N1, displayed a significant decrease in amplitude with the onset of Stage 2 sleep. A later N2 peaked at about 250 ms in the waking state. This changed into a sleep-specific negative wave peaking at 300 ms (N300) at the alpha-theta transition within Stage 1. The P300 displayed a similar shift to become a P450 in Stage 2 sleep. N550 was specific to Stage 2, and was larger in response to rare, rather than frequent stimuli. There was no evidence of any enhancement to relevant rare stimuli compared with irrelevant rare stimuli.     

Are Religious Women More Traditionalist? A Cross-National Examination of Gender and Religion

Does national context shape the relationship between religious attendance and women's gender ideologies? Although previous studies have examined gender and religion within a single national context (and often in a single faith community), few have done so using a cross-national comparative perspective. This has left a significant gap in our understanding of how gender and religion operate in distinctive national contexts. Relying on survey data collected in 37 countries, this study analyzes how the relationship between religious attendance and women's gender ideologies is conditioned by their country's gender inequality. The findings indicate that while women's religious attendance is, on average, negatively related to egalitarian gender ideologies, this association is conditioned by religious affiliation. The relationship is also contingent on the level of gender inequality experienced, and grows weaker in countries with more prominent gender inequality. This study reveals the mechanisms that contextualize the intersection of gender and religion.     

Pain appraisal and quality of life in 108 outpatients with rheumatoid arthritis

Individual differences in emotional functioning, pain appraisal processing, and perceived social support may play a relevant role in the subjective experience of pain. Due to the paucity of data regarding individuals with Rheumatoid Arthritis (RA), the present study aimed to examine pain intensity, emotional functioning (psychological distress and alexithymia), pain appraisal (pain beliefs, pain catastrophizing, and pain-related coping strategies) and social support, and their relationships with the health-related quality of life (HRQoL) in patients with RA. Data were collected from 108 female patients diagnosed with RA. Clinically relevant levels of depressive and anxiety symptoms assessed by the HADS subscales were present in 34% and 41% of the patients, respectively, and about 24% of them exhibited the presence of alexithymia. The results of hierarchical multiple regression analyses showed that pain intensity, alexithymia, the maladaptive beliefs regarding the stability of pain and the coping strategy of guarding explained 54% of the variance in the physical component of HRQoL (p < 0.001). Depression subscale of the HADS, alexithymia, the coping strategy of resting, and the rumination factor of pain catastrophizing significantly explained 40% of the variance in the mental component of HRQoL (p < 0.001). The present findings provide evidence regarding the importance of emotional functioning and pain appraisal in the negative impact of RA on patients’ quality of life. These findings provide additional evidence for the biopsychosocial model of chronic pain, further supporting the complex interaction between emotional, cognitive, and behavioral processes in patients with chronic pain.

Pilot randomised controlled trial of counselling in a community mental health setting: Pitfalls and learnings

The establishment of counselling and psychotherapy as “evidence‐based” interventions is contingent on the effective implementation of randomised controlled trials (RCTs) in real‐world clinical settings. This paper identifies some of the pitfalls that led to the termination of a practical RCT in a community mental health setting. It reflects upon the significance of the lessons learned by drawing on similar challenges that are documented in the wider literature. Issues surrounding staff turnover, counsellor engagement and procedural clarity are discussed, as is the conflict between the time required for research procedures and counsellors’ clinical time constraints. In our recommendations, we recognise the decisive role of collaboration and counsellor motivation in research partnerships, and the significance of clinical relevance, communication, training and research co‐production in achieving them. Time commitment is identified as the pivotal challenge in the formation and maintenance of collaborative research, but one that also must be overcome for the advancement of the counselling and psychotherapy field.
