Social connectedness as a source and consequence of meaning in life

Multiple studies have shown that the sense of belonging and connectedness contribute to meaning in life, but does meaning also influence social connectedness? The present research examines the reciprocal relationships between meaning and different types of connectedness: intimate, relational, and collective. Analyzing data from a nationally representative longitudinal study (Study 1) with cross-lagged panel models, we found that only collective connectedness was prospectively associated with meaning, whereas meaning was prospectively associated with all three types of connectedness, controlling for life satisfaction. The beneficial effect of meaning extended to behavioral indicators of collective and intimate connectedness (Study 2). Higher levels of meaning in life were prospectively associated with an increased likelihood of joining voluntary associations and getting married, and, for people high in marital satisfaction, with a decreased likelihood of marital separation. Together, these findings suggest that the relationship between social connectedness and meaning in life is bidirectional.     

Human Rights and Religion: A Sociological Perspective

This essay aims to review mainstream literature and research perspectives on the sociology of human rights with the further focus on relationship between human rights and religion. We consider the challenges of late engagement of sociology with human rights and current narratives of the relationship of human rights and religion that encompass normativity as the central category of historically oriented sociology. We discuss the contribution of two empirical research mainstreams on human rights and religion and focus on a new field of study—sociology of religious freedom. A detailed new agenda for sociological research on human rights and religion is explored in the final part of our assessment.     

Pigeons' recognition of partially occluded objects depends on specific training experience

DiPietro et al (2002 Perception 31 1299-1312) reported a dramatic improvement in pigeons' recognition of partially occluded objects after the birds had been trained to recognize objects that were placed on top of another surface. Here, we investigated whether training with partially erased stimuli or with notched stimuli that had a thin gap between the object and another surface would similarly enhance pigeons' recognition of partially occluded objects. We found that erased training had no effect on the birds' recognition of partially occluded objects. Training pigeons to recognize notched objects improved their performance with the same objects when they were partially occluded; but this improvement did not transfer to novel objects, a result that DiPietro et al reported after on-top training. Together, the present results and those of DiPietro et al implicate prior experience as a key factor in pigeons' recognition of partially occluded objects. Training experiences which improve recognition of partially occluded objects may do so because they improve decomposition of complex two-dimensional scenes by pigeons into separate entities.     

“Ridiculous” dream versus social contract: Dostoevskij, Rousseau, and the problem of ideal society

Drawing on the Second Discourse and the Social Contract and Notes from Underground and “The Dream of a Ridiculous Man,” this essay examines the striking similarities and fundamental differences between Dostoevskij’s and Rousseau’s treatment of the problem of individual vs. society and their notions of ideal social relations. The essay investigates Rousseau’s attempt to absorb morality into politics and “to concretize” Diderot’s universal moral man into citizen. It also suggests that Dostoevskij takes Rousseau’s attempt at concretization a step further by exposing humanist conceptions of man and society in general as fiction and creating a model of ideal society that absorbs morality, not into politics (as does Rousseau’s model), but into the sanctity of the Word.     

"I Can Tell You If I'll Really Lose All That Weight": Dispositional and Situated Optimism as Predictors of Weight Loss Following a Group Intervention

Weight loss is difficult to achieve and predict. We used Carver & Scheier's (1998 ) self-regulation theory to investigate the role of dispositional and situated optimism in weight loss following a group intervention. The theory proposes that dispositional optimism is related to persistence in goal pursuit as a result of greater confidence in goal attainment. Findings showed that situated optimism (higher goals, greater confidence in their attainment) predicted greater weight loss; whereas dispositional optimism, perceptions of controllability, timeline, and consequences of the weight problem were unrelated to weight loss. Changes in situated optimism following the intervention were related to weight-loss success/failure. The findings suggest that people possess quite accurate knowledge of their chances of success, which could be used to tailor interventions to participants.     

The influence of working memory on reading growth in subgroups of children with reading disabilities

This 3-year longitudinal study determined whether (a) subgroups of children with reading disabilities (RD) (children with RD only, children with both reading and arithmetic deficits, and low verbal IQ readers) and skilled readers varied in working memory (WM) and short-term memory (STM) growth and (b) whether growth in an executive system and/or a phonological storage system mediated growth in reading performance. A battery of memory and reading measures was administered to 84 children (11-17 years of age) across three testing waves spaced 1 year apart. The results showed that skilled readers yielded higher WM growth estimates than did the RD groups. No significant differentiation among subgroups of children with RD on growth measures emerged. Hierarchical linear modeling showed that WM (controlled attention), rather than STM (phonological loop), was related to growth in reading comprehension and reading fluency. The results support the notion that deficient growth in the executive component of WM underlies RD.     

Age differences in the distractor-ratio effect as a function of contrast level

Latencies (RT) and eye movement measures were used to examine the effects of age and contrast on the distractor-ratio effect (DRE) in visual search. Younger and older adults performed a contrast x orientation conjunction search task where the ratios of white to black distractors and luminance contrast levels were varied. The distractor-ratio manipulation had similar effects for older and younger adults on both RT and the number of fixations required to find the target. Both measures were largely independent of distractor ratio on target-present trials, while both RTs and the fixation number increased with the number of items sharing the target's contrast polarity on target-absent trials. A more detailed analysis of eye movements suggested that younger adults were a bit more adept at attending to the smaller set of distractors, which presumably facilitated both overt and covert search. Generalized slowing can account for the age differences in RT, but the fixation number data speak to another mechanism, perhaps increased cautiousness on the part of the elderly when signal strength is low.     

Effects of stimulus duration and choice delay on visual categorization in pigeons

We [Lazareva, O. F., Freiburger, K. L., & Wasserman, E. A. (2004). Pigeons concurrently categorize photographs at both basic and superordinate levels. Psychonomic Bulletin and Review, 11, 1111-1117] previously trained four pigeons to classify color photographs into their basic-level categories (cars, chairs, flowers, or people) or into their superordinate-level categories (natural or artificial). Here, we found that brief stimulus durations had the most detrimental effect on the basic-level discrimination of natural stimuli by the same pigeons. Increasing the delay between stimulus presentation and choice responding had greater detrimental effect on the basic-level discrimination than the superordinate-level discrimination. These results suggest that basic-level discriminations required longer stimulus durations and were more subject to forgetting than were superordinate-level discriminations. Additionally, categorization of natural stimuli required longer stimulus durations than categorization of artificial stimuli, but only at the basic level. Together, these findings suggest that basic-level categorization may not always be superior to superordinate-level categorization and provide additional evidence of a dissociation between natural and artificial stimuli in pigeons’ categorization.     

Regression I. Experimental approaches to regression

The concept of regression is considered with an emphasis on the differences between the positions of Freud and Jung regarding its significance. The paper discusses the results of experimental analyses of individual experience dynamics (from gene expression changes and impulse neuronal activity in animals to prosocial behaviour in healthy humans at different ages, and humans in chronic pain) in those situations where regression occurs: stress, disease, learning, highly emotional states and alcohol intoxication. Common mechanisms of regression in all these situations are proposed. The mechanisms of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the representation of low-differentiated (older) systems in the actualized experience. In all of the cases of dedifferentiation mentioned above, the complexity of the systemic organization of behaviour significantly decreases.     

Sequential congruency effects: disentangling priming and conflict adaptation

Responding to the color of a word is slower and less accurate if the word refers to a different color (incongruent condition) than if it refers to the same color (congruent condition). This phenomenon, known as the Stroop effect, is modulated by sequential effects: it is bigger when the current trial is preceded by a congruent condition than by an incongruent one in the previous trial. Whether this phenomenon is due to priming mechanisms or to cognitive control is still debated. To disentangle the contribution of priming with respect to conflict adaptation mechanisms in determining sequential effects, two experiments were designed here with a four-alternative forced choice (4-AFC) Stroop task: in the first one only trials with complete alternations of features were used, while in the second experiment all possible types of repetitions were presented. Both response times (RTs) and errors were evaluated. Conflict adaptation effects on RTs were limited to congruent trials and were exclusively due to priming: they disappeared in the priming-free experiment and, in the second experiment, they occurred in sequences with feature repetitions but not in complete alternation sequences. Error results, instead, support the presence of conflict adaptation effects in incongruent trials. In priming-free sequences (Experiment 1 and complete alternation sequences of Experiment 2) with incongruent previous trials there was no error Stroop effect, while this effect was significant with congruent previous trials. These results indicate that cognitive control may modulate performance above and beyond priming effects.
