Faith,Fact, and Behaviorism

David Hume argued that ought cannot be derived from is. That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume''s words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.     

Modeling Interactions Between Latent Variables in Research on Type D Personality: A Monte Carlo Simulation and Clinical Study of Depression and Anxiety

Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter. In Study 1, we fitted a multivariate interaction model to predict depression and anxiety with Type D personality, operationalized as an interaction between its two subcomponents negative affectivity (NA) and social inhibition (SI). We constructed this interaction according to four approaches: (1) sum score product; (2) single product indicator; (3) matched product indicators; and (4) latent moderated structural equations (LMS). In Study 2, we compared these interaction models in a simulation study by assessing for each method the bias and precision of the estimated interaction effect under varying conditions. In Study 1, all methods showed a significant Type D effect on both depression and anxiety, although this effect diminished after including the NA and SI quadratic effects. Study 2 showed that the LMS approach performed best with respect to minimizing bias and maximizing power, even when item scores were ordinal and skewed. However, when latent traits were skewed LMS resulted in more false-positive conclusions, while the Matched PI approach adequately controlled the false-positive rate.     

Regional brain activity change predicts responsiveness to treatment for stuttering in adults

Developmental stuttering is known to be associated with aberrant brain activity, but there is no evidence that this knowledge has benefited stuttering treatment. This study investigated whether brain activity could predict progress during stuttering treatment for 21 dextral adults who stutter (AWS). They received one of two treatment programs that included periodic H₂¹⁵O PET scanning (during oral reading, monologue, and eyes-closed rest conditions). All participants successfully completed an initial treatment phase and then entered a phase designed to transfer treatment gains; 9/21 failed to complete this latter phase. The 12 pass and 9 fail participants were similar on speech and neural system variables before treatment, and similar in speech performance after the initial phase of their treatment. At the end of the initial treatment phase, however, decreased activation within a single region, L. putamen, in all 3 scanning conditions was highly predictive of successful treatment progress.     

Mommy is only happy! Dutch mothers’ realisation of speech sounds in infant-directed speech expresses emotion,not didactic intent

Exaggeration of the vowel space in infant-directed speech (IDS) is well documented for English, but not consistently replicated in other languages or for other speech-sound contrasts. A second attested, but less discussed, pattern of change in IDS is an overall rise of the formant frequencies, which may reflect an affective speaking style. The present study investigates longitudinally how Dutch mothers change their corner vowels, voiceless fricatives, and pitch when speaking to their infant at 11 and 15 months of age. In comparison to adult-directed speech (ADS), Dutch IDS has a smaller vowel space, higher second and third formant frequencies in the vowels, and a higher spectral frequency in the fricatives. The formants of the vowels and spectral frequency of the fricatives are raised more strongly for infants at 11 than at 15 months, while the pitch is more extreme in IDS to 15-month olds. These results show that enhanced positive affect is the main factor influencing Dutch mothers’ realisation of speech sounds in IDS, especially to younger infants. This study provides evidence that mothers’ expression of emotion in IDS can influence the realisation of speech sounds, and that the loss or gain of speech clarity may be secondary effects of affect.     

How highlighted utensils influence consumption in a dark setting

Abstract

Objective: Previous research has shown that people consume less food in the dark compared to normal vision conditions. While this effect is commonly attributed to increased attention to internal cues, it could also be caused by increased difficulty to maneuver in a dark setting. This study investigated this potential alternative explanation.

Design: A 2 (dark versus normal vision setting)?×?2 (highlighted versus non-highlighted utensils) between-subjects design was employed.

Main outcome measures: Perceived difficulty of maneuvering and consumption of yoghurt were assessed as main outcome measures.

Results: Participants consumed marginally less in dark compared to normal vision conditions, and experienced higher difficulty of maneuvering. Importantly, both effects were qualified by a significant interaction with highlighting, which increased consumption and reduced perceived difficulty compared to no highlights. Difficulty of maneuvering did not mediate the interactive effect of vision and highlighting on consumption.

Conclusion: Difficulty to maneuver should be considered when investigating eating behaviour under dark conditions. In line with an embodied cognition account, results also reveal the necessity of visual information for interaction with objects in the environment and imply that detail-deprived object information may be sufficient for activation of the motor system.     

Type a behaviour pattern as a risk factor after myocardial infarction: A review

Abstract

This paper is a response to Eiser's (1996) call for a unifying theoretical perspective that would bridge the gap between 'individualistic and ‘social’ approaches to studying human social behaviour in general, and health behaviour in particular. While agreeing with Eiser's premise that it makes no sense to study cognition, affect, and behaviour independently of social context, the present paper takes issue with certain features of his argument that a connectionist approach provides the needed unifying theoretical framework. It is suggested that if connectionism can describe the psychological processes underlying social behavior better than non-connectionist theories, this would provide more compelling evidence of its value than claims that it affords new theoretical insights.     

The Developmental Origin of Metacognition

We explain metacognition as a management of cognitive resources that does not necessitate algorithmic strategies or metarepresentation. When pragmatic, world‐directed actions cannot reduce the distance to the goal, agents engage in epistemic action directed at cognition. Such actions often are physical and involve other people, and so are open to observation. Taking a dynamic systems approach to development, we suggest that implicit and perceptual metacognition emerges from dyadic reciprocal interaction. Early intersubjectivity allows infants to internalize and construct rudimentary strategies for monitoring and control of their own and others' cognitions by emotion and attention. The functions of initiating, maintaining, and achieving turns make proto‐conversation a productive platform for developing metacognition. It enables caregiver and infant to create shared routines for epistemic actions that permit training of metacognitive skills. The adult is of double epistemic use to the infant—as a teacher that comments on and corrects the infant's efforts, and as the infant's cognitive resource in its own right.

Toward a Reconstruction of Medical Morality

At the center of medical morality is the healing relationship. It is defined by three phenomena: the fact of illness, the act of profession, and the act of medicine. The first puts the patient in a vulnerable and dependent position; it results in an unequal relationship. The second implies a promise to help. The third involves those actions that will lead to a medically competent healing decision. But it must also be good for the patient in the fullest possible sense. The physician cannot fully heal without giving the patient an understanding of alternatives such that he or she can freely arrive—together with the physician—at a decision in keeping with his or her personal morality and values. In today's pluralistic society, universal agreement on moral issues between physicians and patients is no longer possible. Nevertheless, a reconstruction of professional ethics based on a new appreciation of what makes for a true healing relationship between patient and physician is both possible and necessary.     

Authentic Humor as an Expression of Spiritual Maturity

SUMMARY

Erikson's understanding of ego integrity and Fowler's depiction of conjunctive faith provide theoretical insights into the holistic nature of spiritual maturity. In order to ground the theory in the actual experience of aging persons, this paper demonstrates, how authentic humor represents an expression of spiritual maturity. Authentic humor can articulate the trust, hope and the faith of elders who maintain a sense of meaning and wholeness despite the changes, losses and suffering which often accompany the aging process. Persons who possess the resource of authentic humor experience the paradoxicalities of aging without yielding to despair.     

Let it be: expatriate couples' adjustment and the upside of avoiding conflicts

This research examines the moderating effect of conflict avoidance on the relationship between conflict and psychological adjustment among 45 expatriate couples at two points in time. We propose a model based on the actor–partner interdependence model, which assumes both intrapersonal and interpersonal effects, to address simultaneously the effects of one's own and the other's avoidance behavior. We found substantial support for our model, especially for expatriate spouses. As expected, and only for expatriate spouses, avoidance moderated the conflict–adjustment relationship such that both one's own and one's counterpart's avoidance behavior diminished the negative effect of conflicts. Because these effects were observed only at T2 and psychological adjustment decreased from T1 to T2, our research suggests that the impact of expatriation-associated interaction particularly manifests itself in the long run.
