Merging Inference and Conjecture by Information

The intuitive notion of a binary relation on information-bearers, comparingthem with respect to their closeness to the available information, is oftenconstrued in terms of comparing their symmetric difference with, orcompositional similarity to, the available information. This happens forinstance in some treatments of verisimilitude. We expound an abstractmathematical rendering of the relevant data-dependent relation in theframework of Boolean algebras. For every element t of a Boolean algebra B we construct the t-modulated Boolean algebra B_tin which the order relation represents `is at most as compatible with t as' or `is at best as similar to t as'. In the case of Lindenbaum-Tarskialgebras, t expresses the available information, and the compatibilityrelation turns out to be an entwinement of inferential and conjecturalrelations. It is just classical entailment when no information is available(i.e., when t is logically true) and becomes more boldly abductive themore information is available. The rich algebraic structures of a Boolean algebra –- including its Boolean group structures –- play a significant role in this combination of deduction and abduction and also induce cautious anddaring variants of the compatibility relation. Links with the literature onverisimilitude, abduction, and related topics are indicated.     

Multisensory Stimulation to Improve Low- and Higher-Level Sensory Deficits after Stroke: A Systematic Review

The aim of this systematic review was to integrate and assess evidence for the effectiveness of multisensory stimulation (i.e., stimulating at least two of the following sensory systems: visual, auditory, and somatosensory) as a possible rehabilitation method after stroke. Evidence was considered with a focus on low-level, perceptual (visual, auditory and somatosensory deficits), as well as higher-level, cognitive, sensory deficits. We referred to the electronic databases Scopus and PubMed to search for articles that were published before May 2015. Studies were included which evaluated the effects of multisensory stimulation on patients with low- or higher-level sensory deficits caused by stroke. Twenty-one studies were included in this review and the quality of these studies was assessed (based on eight elements: randomization, inclusion of control patient group, blinding of participants, blinding of researchers, follow-up, group size, reporting effect sizes, and reporting time post-stroke). Twenty of the twenty-one included studies demonstrate beneficial effects on low- and/or higher-level sensory deficits after stroke. Notwithstanding these beneficial effects, the quality of the studies is insufficient for valid conclusion that multisensory stimulation can be successfully applied as an effective intervention. A valuable and necessary next step would be to set up well-designed randomized controlled trials to examine the effectiveness of multisensory stimulation as an intervention for low- and/or higher-level sensory deficits after stroke. Finally, we consider the potential mechanisms of multisensory stimulation for rehabilitation to guide this future research.     

The Relationship Between Secondary Traumatic Stress and Personal Posttraumatic Growth: Personality Factors as Moderators

This present study examined the relationship between secondary traumatic stress, personality factors, and personal posttraumatic growth for persons indirectly exposed to traumatic life events. A sample of 162 nurses and physicians completed the self-report measures describing symptoms of secondary traumatic stress, personality factors and vicarious posttraumatic growth. The results indicated that secondary traumatic stress negatively correlated with vicarious posttraumatic growth. Moreover, this relation is moderated by personality factors. A low level of secondary traumatic stress symptoms is associated with a higher level of perceived posttraumatic growth for participants with a high level of openness, agreeability and conscientiousness. These findings emphasize the differences in perceiving posttraumatic growth in the context of secondary exposure to traumatic life events.     

Personality and its links to quality of life: Mediating effects of emotion regulation and self-efficacy beliefs

We investigated the relationship between personality and quality of life (QoL) considering emotion regulation and self-efficacy beliefs as mediating factors. A total of 409 participants from the French-speaking regions of Switzerland and from France completed questionnaires on personality, emotion regulation, self-efficacy beliefs, and QoL. Our findings revealed that specific personality traits have significant direct and indirect effects on QoL, mediated by emotion regulation and self-efficacy. Particularly, neuroticism was strongly and negatively related to emotion regulation and QoL, but not significantly linked to self-efficacy, whereas extraversion and conscientiousness were positively associated with all variables. This is the first study to demonstrate that both emotion regulation and self-efficacy are important mechanisms that link specific personality traits to QoL, suggesting that they channel and modulate the personality effects. However, more work is needed to understand these relationships in more detail (e.g., how the personality traits concurrently influence each other as well as emotion regulation and self-efficacy).     

Belastungen in der Kindheit und in der Jugend Essgestörter

Depending on definition and sample, a minority of varying size of women with eating disorders report to be victims of sexual and/or physical abuse. These stressful experiences are risk factors for mental disorders in general and not specifically for eating disorders. Parental high expectations and pre-morbid negative self-evaluation seem to be specific risk factors for anorexia nervosa and bulimia nervosa. Probably, patients with bulimia nervosa suffered more childhood adversity than those with restrictive anorexia nervosa. Patients with a history of sexual and/or physical abuse may be more severely ill and more difficult to treat than other patients with eating disorders. Careful questioning about childhood adversity seems advisable. In therapy, maintaining factors—like problems of self-esteem—are more important than predisposing or precipitating factors. For prevention, it is recommended to provide for the safety of children when treating their parents with mental illness—particularly substance use disorders—and to avoid parental high expectations.     

Disengagement in work‐role transitions

The present study examines whether disengagement from previous work‐roles positively predicts adaptation to a new work‐role (here, becoming self‐employed) by reducing negative consequences of psychological attachment to these previous roles. Disengagement involves an individual's effort to release attention from thoughts and behaviours related to the previous work‐role. A three‐wave longitudinal study investigated the relationship between psychological attachment (measured as affective commitment) to a prior work‐role, disengagement from the prior work‐role, and adaptation to a new work‐role [pursuit of learning, fit perceptions with self‐employment, task performance over time]. Participants included 131 persons who recently founded a small business. Results indicated that psychological attachment to the past work‐role was negatively related to pursuit of learning and fit with the new work‐role. Disengagement from the past work‐role was positively related to pursuit of learning in the new work‐role, and buffered the negative relationship between psychological attachment and fit as well as task performance.     

From Intentions to Behavior: Implementation Intention,Commitment, and Conscientiousness1

Implementation intentions are said to transfer control over goal‐directed behavior to situational cues, thereby automating initiation of the behavior ( Gollwitzer, 1999 ). Alternatively, implementation intentions may be effective because they create commitment to the intended behavior. In an empirical study, implementation intentions regarding a simple task (rating TV newscasts) varied in their specificity. In addition, explicit commitment to the task was manipulated, and chronic conscientiousness was assessed. Consistent with the commitment hypothesis, general and specific implementation intentions were equally effective in raising level of task performance, and they were no more effective than asking for an explicit commitment to carry out the task. Also, individuals high in conscientiousness were more likely than individuals low on this trait to enact their intentions.     

Goal‐Derived Categories: The Role of Personal and Situational Goals in Category Representations

Prior research often emphasized a stimulus‐based or bottom‐up view of product category representations. In contrast, we emphasize a more purposeful, top‐down perspective and examine categories that consumers might construct in the service of salient (i.e., highly accessible) goals. Specifically, we investigate how the point of view imposed by salient consumer goals might affect category representations assessed by participants’ similarity judgments of food products. A key factor in our study is that we examine both individual and situational sources of variability in goal salience. In addition, we also vary the surface‐level, visual resemblance of the stimulus pairs of foods used in the study. The results suggest that personal goals (e.g., health) and situational goals (e.g., convenience) act in conjunction and exert a systematic impact on category representations. Both types of goals, when salient, enhanced the perceived similarity of goal‐appropriate products and reduced the similarity of product pairs when only one product was ideal for the particular goal. The similarity‐enhancing effect was most pronounced when the surface resemblance between the products was low, and the similarity‐diminishing effect was more apparent when surface resemblance was high. Implications are discussed for current theoretical assumptions regarding categorization in consumer research.
