The Council of Crete

This article offers a critical assessment of the Holy and Great Council of the Orthodox Church that took place in Crete in 2016. It argues that the situation facing the Orthodox churches after the Council of Crete is far more important than everything that directly preceded it, and that the Orthodox are only at the beginning as far as the important questions and challenges of the world today are concerned.     

Effects of an adult's presence on the social behavior of preschool children

The social behavior of same-sex pairs of nursery school children was observed during two ten-minute play sessions. One half of the pairs played alone during both sessions, and the remaining pairs played in the presence of a passive adult supervisor. Child pairs who played alone were significantly less aggressive and exhibited a moderate but nonsignificant increase in the expression of positive or prosocial behaviors. Unsupervised pairs also tended to verbalize more and engaged in significantly more cooperative play. The absence of adults may encourage children to employ more mature social strategies to achieve a successful relationship with their playmates.     

Logical reasoning in schizotypal personality

It was examined whether psychotic-like personality traits in a sample of 205 college students could predict logical reasoning deficits, akin to those seen in schizophrenia. The participants were tested on their ability to assess the logical validity of premises (Logical Reasoning Task), and completed a multi-dimensional schizotypy inventory (O-LIFE). Low accuracy was associated with increased levels of disorganized schizotypy (‘Cognitive Disorganization’), while elevated errors were associated with increased levels of positive (‘Unusual Experiences’), negative (‘Introvertive Anhedonia’) and impulsive (‘Impulsivity Non-conformity’) schizotypy. Nevertheless, multiple regression analyses revealed that negative schizotypy was retained as the only significant predictor after performance was corrected for random guessing, and the contribution of the average amount of time spent on each premise was controlled. The results suggest that, although most schizotypy dimensions have a detrimental effect on reasoning performance, possibly due to disadvantageous test-taking strategies, negative schizotypy is the most reliable predictor of logical reasoning deficits. It is proposed that social/interpersonal schizotypal traits, like negative symptoms of schizophrenia, are accompanied by deficient executive functions of working memory, which appear to undermine, inter alia, logical reasoning processing.     

Does Motivation Impact OCD Symptom Severity? An Exploration of Longitudinal Effects

Understanding the role of patient motivation in OCD treatment is of clinical importance given the requisite autonomous role of patients in Exposure and Response Prevention. The present study investigated state- and trait-like relations between three variables: two previously established motivational constructs, readiness to change (RTC) and committed action (CA), derived from the University of Rhode Island Change Assessment, and OCD symptom severity as measured by the self-report Yale-Brown Obsessive Compulsive Scale (Y-BOCS-SR). Utilizing a random-intercept cross-lagged panel model (RI-CLPM) design, we assessed autoregressive, within-time correlations, and cross-lagged effects of RTC, CA, and Y-BOCS-SR scores at admission, month 1 of treatment, and discharge from an intensive/residential treatment program for OCD. Results revealed significant autoregressive (i.e., state-like) effects for CA and Y-BOCS-SR, negative within-time correlations between state CA and Y-BOCS-SR across all time points, a positive within-time correlation between state CA and RTC at admission, and a cross-lagged effect between state Y-BOCS-SR at month 1 of treatment and state RTC at discharge. Results also demonstrated that the stability of the RTC variable was attributable to trait-like factors in the present sample. This study is novel in its use of RI-CLPM in an OCD sample and represents an important addition to the literature on the longitudinal impacts of dynamic constructs of motivation. Our findings may provide future researchers with strategies to supplement ERP with CA-driven motivational interviewing.     

Association between substance use disorders and self- and other-directed aggression: An integrated model approach

Our study's objective is to determine whether substance use disorders’ association with aggression differs according to the type of substance and/or the form of aggression, within the same population. We used data from the National Survey on Drug Use and Health across 2008–2014, with a pooled sample of 270,227 adult respondents. We used regression models to estimate the odds ratios for those having alcohol and/or drug use disorder(s) perpetrating (a) each form of aggression compared with no aggression and (b) other-directed compared with self-directed aggression. Alcohol use disorder alone and drug use disorder(s) alone were both associated with significantly increased odds of committing self-directed, other-directed, and combined aggression. Individuals with drug use disorder(s) alone were more likely to commit other-directed than self-directed aggression (adjusted odds ratio = 1.46, 95% CI = 1.04–2.05). Individuals with alcohol use disorder alone were not likely to commit one over the other (adjusted odds ratio = 1.20, 95% CI = 0.90–1.61). In conclusion, the integrated model of aggression based on the stress–diathesis model is a relevant framework to study risk factors for aggression. Further research is needed to identify longitudinal predictors of directionality of aggression.     

HIV-positive pregnant women attending the prevention of mother-to-child transmission of HIV/AIDS (PMTCT) services in Ethiopia: economic productivity losses across urban-rural settings

HIV/AIDS impacts significantly on pregnant women and on children in Ethiopia. This impact has a multiplier effect on household economies and on productivity losses, and is expected to vary across rural and urban settings. Applying the human capital approach to data collected from 131 respondents, this study estimated productivity losses per HIV-positive pregnant woman–infant pair across urban and rural health facilities in Ethiopia, which in turn were used to estimate the national productivity loss. The study found that the annual productivity loss per woman–infant pair was Ethiopian birr (ETB) 7,433 or United States dollar (US$) 378 and ETB 625 (US$ 32) in urban and rural settings, respectively. The mean patient days lost per year due to inpatient admission at hospitals/health centres was 11 in urban and 22 in rural health facilities. On average, urban home care-givers spent 20 (SD = 21) days annually providing home care services, while their rural counterparts spent 23 days (SD = 26). The productivity loss accounted for 16% and 7% of household income in urban and rural settings, respectively. These high and varying productivity losses require preventive interventions that are appropriate to each setting to ensure the welfare of women and children in Ethiopia.     

Tactile gap detection and language lateralization

Recent work suggests that hemispheric language lateralization might be related to the fine-grained temporal discriminations that are required for linguistic processing (Nicholls, 1996). Studies concerning tactile processing have also shown a significant left-hemisphere (L-H) advantage for tactile gap detection (Nicholls & Whelan, 1997). We hypothesized that language and tactile processing are both preferentially processed by the left hemisphere because it is specialized for tasks requiring fine-grained temporal resolution. Thirty-two participants (16 right and 16 left handers) were tested for both linguistic processing (using the Fused Dichotic Words Test (FDWT)) and tactile gap detection. Both right and left handers showed a significant L-H advantage for both language processing and tactile gap detection. The present study supports recent claims that language lateralization is attributable to the left hemisphere's better suitability to process tasks that require fine-grained temporal resolution.     

A cognitive-behavioral analysis of parental facilitation of children's social-cognitive problem solving

The present study used a case study framework to examine ways in which parental belief systems and parental teaching strategies interact to enhance children's social-cognitive problem solving and school adjustment. The focus of the investigation was to examine the robustness of several postulated typologies of interrelationship among the key variables, as well as antecedents and consequences of means-ends problem solving exhibited by children. Four intact families with second grade children were observed in the home as they participated in discussion and decision making concerning problematic social situations. The data suggested these major points: Parental behavior was generally consistent with their beliefs; parents could most effectively elicit means-ends verbalizations from children through direct questioning; families differed in the extent to which children's inputs into family decision making were valued and the degree of interparental discord concerning beliefs and strategies. The latter points suggest a reconceptualization of how parental variables can be linked to the development of social-cognitive and behavioral competence in children. Specific implications for theory and recommendations for research are discussed.     

The importance of ‘mass’ in line drawings of faces

Previous research (Davies, Ellis and Shepherd, 1978; Rhodes, Brennan and Carey, 1987) has shown that accurate line drawings of familiar faces are identified rather poorly. However, artists can produce lifelike portraits with pen and ink, and Pearson and Robinson (1985) described an automatic method for producing computer-drawn sketches (‘cartoons’) of faces which appear very similar to those produced by a human artist. In this paper we show that subjects can identify famous faces depicted in such computer-drawn ‘cartoons’ almost as well as full grey-scale images. The cartoon algorithm comprises two components. One component draws lines at the locations of intensity changes corresponding to luminance valleys and edges (the ‘valledge’ detector). The other component applies a ‘threshold’ to the original intensity distribution, and replaces any area darker than threshold with black. Thus the full cartoon contains both ‘line’ and ‘mass’. Neither the valledges nor the threshold components alone were as well identified as full cartoons containing both components. The results suggest that the addition of the threshold component adds significantly to the identifiability of line drawings of faces.
