Grouping illumination frameworks

According to Koffka (1935), the lightness of a target surface is determined by the relationship between the target and the illumination frame of reference to which it belongs. However, each scene contains numerous illumination frames, and judging each one separately would lead to an enormous amount of computing. Grouping those frames that are in the same illumination would simplify the computation. We report a series of experiments demonstrating that nonadjacent regions of the visual field under the same illumination level are perceptually grouped together and function, to some extent, as a single framework. A small coplanar group of patches under its own illumination exhibits compression of perceived range of gray shades. We obtained the reduction in compression in the presence of an identically illuminated 25-patch Mondrian tableau mounted nearby the coplanar group. The influence of the Mondrian display was reduced when it was (a) moved laterally away from the test display, (b) moved farther back in depth from the test display, or (c) rotated to a different orientation.     

How do loss- and restoration-oriented coping change across time? A prospective study on adjustment following spousal bereavement

Background and objectives: According to the Dual Process Model (DPM), shifting between loss-oriented (LO) and restoration-oriented (RO) coping is essential for adjustment following bereavement. Knowledge about how LO and RO coping change over time and how such changes are related to adjustment is missing. With a prospective design this study investigated (1) relations between levels of LO/RO coping and selected outcomes and (2) changes in LO/RO coping across time and their relations to adjustment.

Methods: A sample of 145 spousal bereaved individuals completed questionnaires measuring LO and RO coping, grief symptoms, positive affect, and attachment orientation approximately 2–3 months (baseline) and 7 months (follow-up) post-loss.

Results: High usage of LO coping was associated with poorer outcomes and high usage of RO coping was associated with better outcomes at both baseline and follow-up. Individuals generally shifted towards more RO coping across time and those who exhibited this shift showed lower levels of grief at follow-up compared to individuals who changed towards more LO coping across time.

Conclusions: Individuals showing more RO coping reported better adjustment both early and later in the bereavement process. Changes in coping orientation over time might be useful for understanding complicated grief reactions following loss.

People with physical disability in Serbia: Relationship between internalized stigma,experienced and anticipated discrimination,and empowerment

The aim of present study was to explore relationships between experienced and anticipated discrimination, internalized stigma, and empowerment among people with physical disabilities in Serbia. The convenience sample consisted of persons with different types of physical disabilities. The following scales were administrated: The Discrimination and Stigma Scale, the Internalized Stigma of Mental Illness Scale, and the Boston University Empowerment Scale. An analysis showed that internalized stigma was correlated with experienced and anticipated discrimination and empowerment, while no correlation was found between empowerment and discrimination. People with physical disabilities who experienced and anticipated discrimination are at higher risk of reporting internalized stigma.     

Logical Foundations and Kant's Principles of Formal Logic

The abstract status of Kant's account of his ‘general logic’ is explained in comparison with Gödel's general definition of a formal logical system and reflections on ‘abstract’ (‘absolute’) concepts. Thereafter, an informal reconstruction of Kant's general logic is given from the aspect of the principles of contradiction, of sufficient reason, and of excluded middle. It is shown that Kant's composition of logic consists in a gradual strengthening of logical principles, starting from a weak principle of contradiction that tolerates a sort of contradictions in predication, and then proceeding to the (constructive) principle of sufficient reason, and to a classical-like logic, which includes the principle of excluded middle. A first-order formalisation is applied to this reconstruction, which reveals implicit modalities in Kant's account of logic, and confirms the implementability of Kant's logic into a sound and complete formal system.     

A Prospective Study of High-School Adolescent Sexting Behavior and Psychological Distress

Abstract

Relying on conceptualization of sexting as a deviant behavior, which appear to be related with mental health problems, we examined the relationship between sexting and psychological distress. A one-year longitudinal study was performed among 216 girls and 143 boys, aged from 15 to 17?years (M?=?16.32, SD = .64). Participants completed the Sexting Behavior Questionnaire and the Depression Anxiety and Stress Scale at both time points of the study. The results showed that the prevalence for receiving sexts between the two time points was around 30%, and for sending sexts around 60%. The prevalence rates of receiving and sending sexually explicit context were quite stable over time, though they varied significantly across gender. Participants usually had sexted with a current or (ex)partner or friends. The number of person with whom participants exchange sexts did not exceed five. Anxiety and stress symptoms were more prevalent among sexters who receive sexts at the baseline than follow-up study (p < .05). Stress has been found to be significant predictors of sending sext at the baseline study (p < .05), while depression of receiving and sending at the follow-up study (p < .001). This study confirms that sexting is common among youth, and appears to be associated with negative consequences.     

Listening comprehension in preschoolers: The role of memory

The current study analyzed the relationship between text comprehension and memory skills in preschoolers. We were interested in verifying the hypothesis that memory is a specific contributor to listening comprehension in preschool children after controlling for verbal abilities. We were also interested in analyzing the developmental path of the relationship between memory skills and listening comprehension in the age range considered. Forty‐four, 4‐year‐olds (mean age = 4 years and 6 months, SD =4 months) and 40, 5‐year‐olds (mean age = 5 years and 4 months, SD =5 months) participated in the study. The children were administered measures to evaluate listening comprehension ability (story comprehension), short‐term and working memory skills (forward and backward word span), verbal intelligence and receptive vocabulary. Results showed that both short‐term and working memory predicted unique and independent variance in listening comprehension after controlling for verbal abilities, with working memory explaining additional variance over and above short‐term memory. The predictive power of memory skills was stable in the age range considered. Results also confirm a strong relation between verbal abilities and listening comprehension in 4‐ and 5‐year‐old children.
