Exercise as a buffer of life stress: a prospective study of adolescent health

The hypothesis that physical exercise provides benefits to individuals under periods of life stress has rarely been subject to empirical verification. This article presents the results of a longitudinal study of stress and well-being in adolescence in which the ability of exercise to buffer stress-induced deteriorations in physical health was examined. In accordance with predictions, prospective analyses revealed that the negative impact of stressful life events on health declined as exercise levels increased. These findings suggest that exercise may be a valuable resource for combating life stress. Discussion centers on possible mediating mechanisms and on the practical implications of the results.     

The associative basis of contingent color aftereffects.

According to a conditioning analysis of the orientation-contingent color aftereffect (McCollough effect, ME), orientation stimulus (grids) become associated with color. Contrary to this interpretation are reports that simple forms cannot be used to elicit illusory color and that the ME is not degraded by decreasing the grid-color correlation. The present results indicate: (a) Form stimuli can contingently elicit color aftereffects; (b) even a non-patterned stimulus--the lightness of a frame surrounding a colored area--can contingently elicit color aftereffects; (c) this frame lightness-contingent aftereffect, like the ME, persists for at least 24 hr; and (d) the frame lightness-contingent aftereffect can be used to demonstrate that correlational manipulations affect the ME, as they affect other types of conditional responses.     

Information processing abilities and performance on two perceptual-motor tasks

The purpose of this study was to investigate whether the hypothesized information-processing mechanisms, thought to be reflected by the slope and intercept of the regression of choice reaction time on stimulus information or information transmitted could account for performance on two novel laboratory tasks. In addition, analyses were performed to determine whether these theorized mechanisms represent stable within individual abilities or task specific capabilities. Analysis indicated that the slopes obtained from two different choice reaction time paradigms were unrelated while intercepts were moderately correlated. Examination of the pattern of zero-order correlations further showed that regression components were not meaningfully related to performance on either novel task, suggesting that knowledge of information-processing mechanisms, as assessed in choice RT paradigms, did not enhance the understanding of performance in more complex tasks.     

Deep dyslexia in childhood?

Deep dyslexia is an acquired reading disorder in which semantic substitutions (e.g., city read as town) are made in reading single isolated words. In this paper, evidence for deep dyslexic-type errors is presented from the word-recognition responses of six children, aged 7 years and 0 month to 8 years and 9 months, with severe reading disorders. These semantic substitutions occur in the absence of phonological skills. Therefore, it appears that there exists a small subset of developmental dyslexics who at the beginning of acquisition of reading skills are able to engage in semantic processing, but who show severe impairment of phonological processing. The existence of these reading errors indicate that the use of a phonological code is not necessary to extract meaning from the printed word.     

Mediation in custody disputes

This article summarizes the results of an evaluation of mediation services in three court-based programs. Among the issues considered are client evaluations of the mediation experience and their assessments of immediate and long-term effects. Two comparison groups are utilized: parents who contested custody without the offer of court-based mediation and parents who divorced but did not contest custody. Results of the research indicate that mediation provides a valuable compliment to the existing domestic relations court processes. Mediation enjoys high user satisfaction and helps promote compliance with the agreement, a sense of equity, and continued cooperation. Thus, while the expectations of the process should not be overstated, it appears that even a brief mediation with a troubled population can produce modest but positive benefits.     

Effects of family therapy for substance abuse: A systematic review of recent research

One of the most serious psychosocial problems worldwide is substance abuse because of its repercussions not only on the physical and psychological health of the abuser but also on their relational functioning. Among the well-established therapeutic approaches for the treatment of substance abuse is family therapy, which, in addition to influencing personal variables, promotes changes in family dynamics. The main objective of this study is to review the scientific literature published from 2010 to the present on the efficacy and effectiveness shown by family-based treatment approaches for substance use problems both in adolescent and adult samples. In addition, the effect on secondary variables such as family functioning and behavioral problems is evaluated. The empirical evidence accumulated in the last decade and reviewed in the present study indicates that the incorporation of family members in the treatment of substance abuse produces benefits by diminishing consumption and improving family functioning. Limitations of this study and of the research reviewed are discussed and directions for future research are provided.     

Seeing in the Dark: A View into Dissociation and Healing

In this paper, I will explore the role of art-making, the experience of trauma and dissociation, and the process of working with self-states from an analytic and creative frame. Relevant literature on dissociation, trauma, and the use of art will be discussed. A case involving my work with an adolescent girl who had experienced sexual abuse from a family member will be shared, with an emphasis on the meaningful role images played during the therapeutic process. Both Jungian and psychoanalytic models of conceptualizing and working with dissociation are included, following Donald Kalsched’s (2013) recommendation for a “binocular stance” to treatment, including both a focus on the inner, intrapsychic world and the interpersonal, relational realm, and how art images both illuminated and expressed these realms. Within the therapeutic process, art images allowed the therapist a view into the client’s unconscious process, and created a meeting ground for dissociative barriers to be gradually seen, felt and known, by both therapist and client. The experience of dissociation, in images and in session, provided a reference point for myself and my client, Taylor, to develop a shared understanding and a framework for growth.     

Mathematical Practice,Fictionalism and Social Ontology

From the perspective of mathematical practice, I examine positions claiming that mathematical objects are introduced by human agents. I consider in particular mathematical fictionalism and a recent position on social ontology formulated by Cole (2013, 2015). These positions are able to solve some of the challenges that non-realist positions face. I argue, however, that mathematical entities have features other than fictional characters and social institutions. I emphasise that the way mathematical objects are introduced is different and point to the multifaceted role that relations and interconnections play in this context. Finally, I argue that mathematical entities can be considered to be pragmatically real.

     

Perceived brand authenticity: Examining the effects of inferred dedication and anticipated quality on consumers' purchase intentions and actual choices

This research investigates both the downstream effect of perceived brand authenticity on consumers' actual, consequential choice and the important role of inferred brand dedication in the relationship between perceived brand authenticity, anticipated quality, and purchase intentions. We also investigate the interactive effect of two source-related factors—intrinsic motivation and congruity—on consumers' brand authenticity perceptions. We present findings from three studies using different product categories (utilitarian/consumable: hand sanitizer; hedonic/consumable: chocolate; hedonic/non-consumable: sunglasses). Study 1 shows that consumers use information regarding the intrinsic motivation of those behind the brand and congruity between the brand's actions and what it represents to consumers when forming brand authenticity perceptions and that intrinsic motivation and congruity interact to increase authenticity perceptions. We anticipate that consumers' positivity toward brands perceived as authentic will extend to actual choice through anticipated quality. Study 2 demonstrates that consumers choose authentic brands over inauthentic brands above what chance would dictate and anticipated quality can forecast this choice. Next, we extend our collective process knowledge by exploring an underlying reason why consumers anticipate that brands presented through marketing communications as authentic will have higher quality. We suggest that when managers present brands as authentic, consumers infer greater dedication of those behind the brand and inferred dedication influences anticipated product quality. Study 3 provides support and uncovers a serial mediation process, highlighting the importance of inferred dedication. Specifically, perceived brand authenticity increases consumers' brand dedication inferences, which in turn increases anticipated product quality, and ultimately purchase intentions.
