Dissociating mere exposure and repetition priming as a function of word type

The mere exposure effect is defined as enhanced attitude toward a stimulus that has been repeatedly exposed. Repetition priming is defined as facilitated processing of a previously exposed stimulus. We conducted a direct comparison between the two phenomena to test the assumption that the mere exposure effect represents an example of repetition priming. In two experiments, having studied a set of words or nonwords, participants were given a repetition priming task (perceptual identification) or one of two mere exposure (affective liking or preference judgment) tasks. Repetition priming was obtained for both words and nonwords, but only nonwords produced a mere exposure effect. This demonstrates a key boundary for observing the mere exposure effect, one not readily accommodated by a perceptual representation systems (Tulving & Schacter, 1990) account, which assumes that both phenomena should show some sensitivity to nonwords and words.     

Learning in a simple motor system

Motor learning is a very basic, essential form of learning that appears to share common mechanisms across different motor systems. We evaluate and compare a few conceptual models for learning in a relatively simple neural system, the vestibulo-ocular reflex (VOR) of vertebrates. We also compare the different animal models that have been used to study the VOR. In the VOR, a sensory signal from the semicircular canals is transformed into a motor signal that moves the eyes. The VOR can modify the transformation under the guidance of vision. The changes are persistent and share some characteristics with other types of associative learning. The cerebellar cortex is directly linked to the VOR reflex circuitry in a partnership that is present in all vertebrates, and which is necessary for motor learning. Early theories of Marr, Albus, and Ito, in which motor memories are stored solely in the cerebellar cortex, have not explained the bulk of the experimental data. Many studies appear to indicate a site of learning in the vestibular nuclei, and the most successful models have incorporated long-term memory storage in both the cerebellar cortex and the brainstem. Plausible cellular mechanisms for learning have been identified in both structures. We propose that short-term motor memory is initially stored in the cerebellar cortex, and that during consolidation of the motor memory the locus of storage shifts to include a brainstem site. We present experimental results that support our hypothesis.     

The relationship of relatives' attributions to their expressed emotion and to patients' improvement in treatment for anxiety disorders

In a test of Hooley's (1987) attributional model of expressed emotion (EE), attributions for negative behaviors and events in patients' lives were examined in relatives of 74 outpatients with panic disorder with agoraphobia or obsessive-compulsive disorder. Attributions were extracted from 10-minute problem-solving interactions between relatives and patients, whereas EE was assessed during a separate interview with the relative. Consistent with prior findings in relatives of individuals with other disorders, relatives who made greater proportions of attributions of patient responsibility demonstrated significantly higher levels of EE-hostility. In addition, nonspousal relatives (mostly parents) who attributed any negative behaviors or events to a patient's disorder were significantly higher in emotional overinvolvement (EOI); no such relationship was found for spouses. Finally, patients with relatives who made attributions to the patient's disorder received less benefit from behavior therapy than did those whose relatives made no such attributions, even when EE variables were controlled.     

Applying “Place” to Research Ethics and Cultural Competence/Humility Training

Research ethics principles and regulations typically have been applied to the protection of individual human subjects. Yet, new paradigms of research that include the place-based community and cultural groups as partners or participants of environmental research interventions, in particular, require attention to place-based identities and geographical contexts. This paper argues the importance of respecting “place” within human subjects protections applied to communities and cultural groups as part of a critical need for research ethics and cultural competence training for graduate research students. These protections and benefits are extensions of the Belmont Principles and have been included in recent recommendations from research regulatory committees.     

Emotion Regulation in Adolescent Well-Being and Positive Education

Emotion regulation (ER) becomes increasingly important across adolescent development, and promotes psychological flexibility, resilience and well-being in youth. Positive education programs (PEPs) combine academic training with positive psychology interventions (PPIs) to increase well-being and reduce mental ill-health. Despite considerable overlap between PPIs and ER models, the role and relevance of ER to PEPs remains unclear. This review aimed to evaluate the relationship of ER to PEPs targeting adolescents. First, to evaluate the relationship of ER to domains of well-being targeted by school-based PPIs. Second, to examine whether school-based PPIs can improve adolescents’ ER capacity. Third, to evaluate the role of ER in well-being outcomes of PEPs. Results support the relevance of ER to domains of well-being outlined by the revised PERMA model, including positive emotions, engagement, relationships, meaning, and health. ER can influence the degree to which students benefit from PEP participation. It remains to be determined whether ER capacity is improved as a result of exposure to positive education programs. Findings are limited by the small and heterogeneous group of interventions examined, and the use of inconsistent ER measures. Further research of the role of ER in positive education may contribute to greater understanding of the mechanisms underlying their effectiveness and further promote the psychological well-being of adolescents.     

A complex dynamic systems approach to lasting positive change: The Synergistic Change Model

This paper argues that psychological and social functioning is fundamentally complex, and that this complexity is critical to understanding how lasting positive changes can be achieved. Principles from complex systems theory are integrated into an empirical positive psychological framework to propose a domain-based systems model of positive change called the Synergistic Change Model. This model proposes that enduring positive change depends on the formation of mutually supportive interactions across multiple domains of psychological and social functioning. The paper uses the model to explore three types of response to intervention – relapse, spill-over, and synergy – which have been supported in the existing positive psychology literature. Three practical intervention strategies arising from the model are outlined to inform the design of future positive interventions. The model challenges reductionistic approaches to positive change and offers several approaches to embrace the complexities of lasting positive change in future theory and research.
