Relational Turbulence Theory: Explaining Variation in Subjective Experiences and Communication Within Romantic Relationships

This essay extends the relational turbulence model as a framework for understanding communication in romantic relationships. Following the relational turbulence model, relational turbulence theory identifies relational uncertainty and interdependence as parameters that shape subjective experiences, but the theory clarifies the theoretical processes underlying their distinctive effects. In addition, relational turbulence theory articulates causal processes linking cognitive appraisals and emotions to communication. Relational turbulence theory also describes how episodes characterized by biased appraisals, intense emotions, and volatile communication coalesce into global evaluations of relationships as turbulent. In turn, the theory addresses the effect of relational turbulence on personal, relational, and social outcomes. Finally, the theory explains how communication can contribute to the development of both turbulence and resilience in romantic relationships.     

Tests of the ratio rule in categorization.

Many theories of learning and memory (e.g., connectionist, associative, rational, exemplar based) produce psychological magnitude terms as output (i.e., numbers representing the momentary level of some subjective property). Many theories assume that these numbers may be translated into choice probabilities via the ratio rule, also known as the choice axiom (Luce, 1959) or the constant-ratio rule (Clarke, 1957). We present two categorization experiments employing artificial, visual, prototype-structured stimuli constructed from 12 symbols positioned on a grid. The ratio rule is shown to be incorrect for these experiments, given the assumption that the magnitude terms for each category are univariate functions of the number of category-appropriate symbols contained in the presented stimulus. A connectionist winner-take-all model of categorical decision (Wills & McLaren, 1997) is shown to account for our data given the same assumption. The central feature underlying the success of this model is the assumption that categorical decisions are based on a Thurstonian choice process (Thurstone, 1927, Case V) whose noise distribution is not double exponential in form.     

Age, gender, and reasons for living among Australian adults

Reasons for living have been identified as protective factors in relation to suicide, and much research has documented gender differences in reasons for living. In contrast, little research has investigated age differences in reasons for living. In the current study, the relationship of age to reasons for living was investigated, as was whether age and gender interact to influence reasons for living. A community sample of Australian adults (N = 970) aged 18 to 95 years (M = 48.40, SD = 20.85) completed the Reasons for Living Inventory. Results for the main effects indicated that being female was associated with higher total, child-related concerns and fear of suicide (FS) scores, whereas increasing age was associated with higher total, responsibility to family (RF), FS, and moral objections scores. Age and gender interacted to influence RF, FS, and fear of social disapproval. For each of these reasons for living, increasing age was associated with higher scores for men; however, there was no association between age and these reasons for living scores among women. Overall, the results indicate that the influence of age, gender, or the combination of the two varies according to the reason for living being investigated.     

Associative history affects the associative change undergone by both presented and absent cues in human causal learning

R. A. Rescorla (2000) noted that a number of influential theories of associative learning do not take the associative history of cues (i.e., the prior training that they have received) into account when calculating the associative change undergone by those cues. The authors tested this assumption in a human causal learning paradigm and found associative history to be an important determinant of the learning undergone by cues that are presented on a trial. Moreover, associative history was also found to influence the amount of retrospective revaluation undergone by absent cues. These findings conflict with models of causal learning in which the associative change undergone by an element of a cue compound is governed by a summed error term (e.g., R. A. Rescorla & A. R. Wagner, 1972).     

Intradimensional and extradimensional shifts in spatial learning

Animals trained on 2 discriminations learn the 2nd rapidly if the relevant stimuli are from the same dimension as the 1st (an intradimensional or ID shift) but slowly if the relevant stimuli for the 2 problems are from different dimensions (an extradimensional or ED shift). Four experiments examined ID and ED shifts in spatial learning. Rats trained on 2 spatial problems learned the 2nd more rapidly than rats whose 1st problem had been nonspatial. But this difference between ID and ED shifts depended on the spatial relationship between rewarded (S+) and unrewarded (S-) alternatives in the 2 spatial problems. The results imply that rats trained on a spatial discrimination do not learn to attend to all spatial landmarks but only to those that serve to differentiate S+ and S-.     

Do Threats Galvanize Authoritarians or Mobilize Nonauthoritarians? Experimental Tests from 19 European Societies

Authoritarian predispositions and contextual threats are both thought to result in intolerance and prejudice towards immigrants and other minorities. Yet there is considerable dispute as to how authoritarianism and threat interact to produce an “authoritarian dynamic.” Some scholars argue that threats increase intolerance by “galvanizing” authoritarians. Others claim that authoritarians are always intolerant toward outgroups, with threat instead “mobilizing” nonauthoritarians. Using experimental manipulations of immigrant cultural threat embedded in nationally representative samples from 19 European societies, this study offers a test of these competing hypotheses. While we find some evidence for the “galvanizing” hypothesis, we find no evidence for the “mobilizing” hypothesis. The effects vary considerably across national samples however, with immigrants from Muslim societies being particularly likely to activate authoritarian predispositions. These findings show how the migration of culturally distinctive groups has the potential to activate authoritarian dispositions, thereby pushing the issue of immigration to the center of political debates.     

Advancing cognitive behaviour therapy for older adults with comorbid insomnia and depression

Insomnia and depression are two of the most common mental health problems that negatively impact older adults. The burden associated with these highly comorbid conditions requires an innovative approach to treatment. There have been significant advancements in the field of cognitive behaviour therapy for insomnia (CBT-I) over recent years. CBT-I has evolved from targeting homogenous insomnia samples to now showing promising results for comorbid insomnia. CBT-I is not only effective at treating comorbid insomnia, but can also have a positive impact on depression severity. Despite these important clinical developments, limited research has explored whether modifying CBT-I programmes to specifically target comorbid depression could improve outcomes for older populations. This paper reviews recent literature and provides therapeutic recommendations to advance CBT-I for older adults with comorbid insomnia and depression.     

Factors Influencing Clinical Correlates of Chronic Traumatic Encephalopathy (CTE): a Review

Chronic traumatic encephalopathy (CTE) is a neuropathologically defined disease reportedly linked to a history of repetitive brain trauma. As such, retired collision sport athletes are likely at heightened risk for developing CTE. Researchers have described distinct pathological features of CTE as well a wide range of clinical symptom presentations, recently termed traumatic encephalopathy syndrome (TES). These clinical symptoms are highly variable, non-specific to individuals described as having CTE pathology in case reports, and are often associated with many other factors. This review describes the cognitive, emotional, and behavioral changes associated with 1) developmental and demographic factors, 2) neurodevelopmental disorders, 3) normal aging, 4) adjusting to retirement, 5) drug and alcohol abuse, 6) surgeries and anesthesia, and 7) sleep difficulties, as well as the relationship between these factors and risk for developing dementia-related neurodegenerative disease. We discuss why some professional athletes may be particularly susceptible to many of these effects and the importance of choosing appropriate controls groups when designing research protocols. We conclude that these factors should be considered as modifiers predominantly of the clinical outcomes associated with repetitive brain trauma within a broader biopsychosocial framework when interpreting and attributing symptom development, though also note potential effects on neuropathological outcomes. Importantly, this could have significant treatment implications for improving quality of life.     

Elemental associability changes in human discrimination learning

Participants initially completed a discrimination task (D1) involving categorization of patterns with multiple common features, each feature being partly predictive of the correct response. In a subsequent target discrimination task (D2), these features were redistributed across new discriminative stimuli. The relative predictiveness of the features in D1 was either maintained in D2 (i.e., features were equally informative in D1 and D2) or switched (i.e., more informative features in D1 were made less informative in D2, and vice versa). Differential performance on D2 suggested that features most predictive of the correct D1 responses became more highly associable than features that were less predictive in D1. This finding suggests that the associability of individual stimulus elements changes as a consequence of their role in discrimination learning.     

Enhancing learning through strategy instruction and group interaction: is active generation of elaborations critical?

We examined strategic intervention when learners were actively engaged in group discussion to assess the impact of peer interaction. In addition, memory performance was compared between students who generated or evaluated elaborations when using the elaborative interrogation strategy, as well as between a supported strategy where learners were provided with explanatory elaborations and a self‐study condition. Introductory psychology students (N=263) in groups of 3 to 5 members studied sixty facts about familiar and unfamiliar animals. Overall, the potency of elaborative interrogation was confirmed regardless of whether students studied interactively or independently. The contribution of group members in facilitating knowledge when the group was able to share sophisticated strategic information also was highlighted. Most critically, when background knowledge was sufficient to promote connections between existing and new material, it was the active generation of elaborations that maximized learning.
