So hard to say goodbye? An investigation into the symbolic aspects of unintended disposition practices

Even though disposition is present in the consumer behavior research agenda, most of the studies focus mainly on intentional movements of products leaving the home. The present article describes a less conscious and co‐incidental journey of products into a liminal zone between use and disposal inside homes. A qualitative field study, based on the itinerary method, was undertaken with a group of 26 affluent women in Brazil. The findings show that consumers maintain purgatories – “forgotten” repositories of products no longer in use – as an in‐home disposition practice. The aspects and functioning of purgatory are also detailed, through a typology of purgatories and a discussion of specific strategies to deal with cluttering as a consequence of product accumulation inside homes. Finally, purgatories emerge as a contemporary consumer solution to deal not with individual products but with product collectivities' disposition. Copyright © 2016 John Wiley & Sons, Ltd.     

Adverse Childhood Experiences and Diabetes in Adulthood: Support for a Collaborative Approach to Primary Care

Prior studies have demonstrated an association between retrospective reports of experiencing trauma in childhood and the current incidence of type 2 diabetes in adulthood. Much less is known about this association among low-income minority patients in primary care settings. We replicated the adverse childhood experiences (ACEs) Centers for disease control and prevention (CDC) study with a low-income minority sample of primary care patients (N = 801) at a community-based healthcare center. We conducted a cross-sectional retrospective quantitative survey study to examine the association between participants’ reports of past childhood trauma and their current health care outcomes. Data were analyzed using binary logistic regression to evaluate the hypothesis that low income minority patients who reported more childhood trauma (abuse, neglect, household dysfunction, cumulative adverse childhood experiences [ACEs]) would more likely be diagnosed with type 2 diabetes. Results suggest that the number of ACEs in our sample were considerably higher than the original CDC ACEs study, as almost 50 % of patients surveyed at our clinic reported 4 or more ACEs, confirming that trauma is central in our urban primary care setting. The results of the cumulative ACEs score was in the expected direction and was significant, suggesting that participants who cumulatively reported experiencing more childhood trauma were more likely to be diagnosed with type 2 diabetes in adulthood. These findings have implications for family therapists, primary care providers, researchers, and policy makers to develop more collaborative approaches to primary care that better target the negative sequelae of ACEs.     

Cerebellum and processing of negative facial emotions: Cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

Watching a cursor distorts haptically guided reproduction of mouse movement

Participants moved a mouse along a force-feedback-defined linear path, either without vision or while watching a cursor set to 1 of 3 levels of visual:haptic gain (all >1:1). They attempted to haptically reproduce the movement without visual feedback. Errors increased with gain, reaching 70% overestimation at the highest gain. Forewarning participants about gain variability did not eliminate this effect. The gain level was potentially cued during the movement by the mismatch between visual feedback and kinesthetic feedback. Moreover, because participants did not achieve cursor-speed constancy across gain levels, visual speed was another cue to gain. Collectively, these cues failed to prevent visual distortion of movement reproduction.     

Influence of dorsal hippocampal lesions and MMP inhibitors on spontaneous recovery following a habituation/classical conditioning head–shake task

The present investigation combined a classical conditioning paradigm with a head–shake response (HSR) habituation task in order to evaluate the importance of dorsal hippocampal neural plasticity to spontaneous recovery. In the first experiment animals exhibited rapid HSR habituation (air stimulus to the ear) and an 85% level of spontaneous recovery following a 24 h inter-session interval. The addition of a brief tone prior to the air stimulus produced a similar pattern of habituation during the first session, but the level of spontaneous recovery was reduced (44%) during Session II. In a second experiment dorsal hippocampal lesioned rats placed on this tone/HSR paradigm responded with an 87% level of spontaneous recovery during Session II; while neocortex lesioned control rats indicated significantly reduced levels of spontaneous recovery (55%). In a third experiment bilateral injections of a general MMP inhibitor, FN-439, into the dorsal hippocampus resulted in high levels of spontaneous recovery (81%); while control rats injected with artificial cerebrospinal fluid displayed a significant attenuation of spontaneous recovery (45%). Finally, animals bilaterally injected with a specific MMP-3 inhibitor into the dorsal hippocampus indicated very similar results to those obtained following FN-439 injection. These findings indicate that animals prepared with dorsal hippocampal lesions, or injections with an MMP inhibitor, revealed an impaired association between the tone and air stimulus thus maximum spontaneous recovery was present 24 h later. Thus, it appears that the dorsal hippocampus influences habituation by conserving responses and reducing spontaneous recovery when a temporally contingent signaling cue is present.     

Stages of manual exploration in haptic object identification

In a yes/no identification task using touch alone, subjects indicated whether an object belonged to a named category. Previously, we found that subjects explored in two stages—first grasping and lifting the object, then executing further exploratory procedures (Lederman & Klatzky, 1990b). We proposed that Stage 1 (grasp/lift) was sufficient to extract coarse information about multiple object properties, whereas Stage 2 was directed toward precise information about particularly diagnostic properties. the current study, subjects were initially constrained to grasping and lifting, after which they could explore further. Accuracy was above chance after Stage 1, confirming our assumption that the grasp/lift combination was broadly useful. Stage 2 increased accuracy and confidence. It primarily elicited exploratory procedures associated with object geometry, but exploration was also influenced by diagnostic object properties.     

Body-esteem, body mass index, and risk for disordered eating among adolescents in synchronized swimming

The aim of this study was to examine dimensions of body-esteem, Body Mass Index, and their relations with eating disorder symptoms among 42 elite adolescent athletes engaged in competitive synchronized swimming (M = 15.4 yr., SD = 1.2) and to compare them with 40 athletes in sports with no emphasis on leanness (M = 16.5 yr., SD = .93), and 50 nonathlete college female students (M = 16.3 yr., SD = 1.1). They completed the Body-esteem Scale and the Eating Attitudes Test, and the Body Mass Index was computed. Analysis showed synchronized swimmers reported greater negative feelings about their appearance than the two other groups and low perceptions of how others evaluate their physical appearance. Participants did not differ on the EAT-26. Regression analyses showed that Body Mass Index and Body-esteem Appearance accounted for 38% of the variance in log-transformed Dieting scores of synchronized swimmers. Results are discussed in relation to the literature.
