How "fun/importance" fit affects performance: relating implicit theories to instructions

People experience a regulatory fit when they employ means of goal pursuit that fit their regulatory orientation, and this fit increases motivation that can enhance performance. The present studies extend previous research on regulatory fit to the classic motivational variables of fun and importance. They also examine for the first time the effect on performance of the fit between individuals' implicit theories about a task's fun or importance and their strategic engagement of the task as fun or important as induced by task instructions. In all three studies, task performance was better when the external task instructions "fit" rather than did not fit participants' implicit theory for the task. The implications of these findings for understanding the motivational effects of fun and importance are discussed.     

Effects of experience on fetal voice recognition

Abstract - The ability of human fetuses to recognize their own mother's voice was examined. Sixty term fetuses were assigned to one of two conditions during which they were exposed to a tape recording of their mother or a female stranger reading a passage. Voice stimuli were delivered through a loudspeaker held approximately 10 cm above the maternal abdomen and played at an average of 95 dB SPL. Each condition consisted of three 2-min periods: no stimulus, voice (mother or stranger), and no stimulus. Fetal heart rate increased in response to the mother's voice and decreased in response to the stranger's; both responses were sustained for 4 min. The finding of differential behavior in response to a familiar versus a novel voice provides evidence that experience influences fetal voice processing. It supports an epigenetic model of speech perception, presuming an interaction between genetic expression of neural development and species-specific experience.     

The neuroendocrinology of posttraumatic stress disorder: new directions

Studies of the hypothalamic-pituitary-adrenal (HPA) axis in persons with posttraumatic stress disorder (PTSD) have produced variable findings. This review focuses on the factors likely to have affected the outcome of these studies, including population characteristics and experimental design. Also discussed is a possible role for the adrenal neurosteroid dehydroepiandrosterone (DHEA) as a mediator of HPA axis adaptation to extreme stress and the psychiatric symptoms associated with PTSD. The antiglucocorticoid properties of DHEA may contribute to an upregulation of HPA axis responses as well as mitigate possible deleterious effects of high cortisol levels on the brain in some PTSD subpopulations. The neuromodulatory effects of DHEA and its metabolite DHEAS at gamma-aminobutyric acid and N-methyl-D-aspartate receptors in the brain may contribute to psychiatric symptoms associated with PTSD. The possible importance of other neurohormone systems in modulating HPA axis and symptom responses to traumatic stress is also discussed. Understanding the complex interactions of these stress-responsive neurosteroid and peptide systems may help explain the variability in patterns of HPA axis adaptation, brain changes, and psychiatric symptoms observed in PTSD and lead to better targeting of preventive and therapeutic interventions.     

Fluency disruption in speech and in wind instrument playing

A case of an adult who stutters and complains of a similar fluency problem when playing the trombone is reported. This is the fourth such report, with previous cases involving trumpet, flute, and horn playing.     

Fleeting Signs of the Course of Life: Facial Expression and Personal Adjustment

In this article, we consider whether facial expressions of emotion relate in theoretically interesting ways to personal adjustment. We first consider the conceptual benefits of this line of inquiry. Then, to anticipate why brief samples of emotional behavior should relate to personal adjustment, we review evidence indicating that facial expressions of emotion correspond to intrapersonal processes and social outcomes. We then review studies showing that facial expressions relate in theoretically significant ways to adjustment after the death of a spouse, in long-term relationships, and in the context of chronic psychological disorders.     

Pain and Pain-Related Impairment in Adults with Cystic Fibrosis

The Multidimensional Pain Inventory (MPI) was utilized in a sample of adult outpatients with cystic fibrosis (CF) to assess their perception of pain and its psychosocial consequences. Subsequently, the data were compared to the ratings of pain and pain-related impairment in these patients as perceived by two nurses from the CF treatment team, as well as to a quantitative measure of illness severity. The results of these comparisons demonstrate that the majority of adult outpatients with CF reported experiencing lower levels of pain and pain-related impairment than expected, although the male patients tend to report experiencing significantly less impact in these domains than do the female patients. Additionally, the nurses do not underestimate the degree to which patients, especially males, experience pain and pain-related interference from chronic illness. Finally, there was no significant relationship between patients' self-report of pain severity or pain-related interference and an objective measure of disease severity.     

Differential maturation of fetal responses to vibroacoustic stimulation in a high risk population

Maturation of human fetal response to vibroacoustic stimulation was examined in 163 high risk fetuses from 23 to 36 weeks gestational age (GA). Each fetus received three vibroacoustic trials and three no-stimulus control trials (randomly assigned) while fetal heart rate (FHR) was recorded and body movement was observed on ultrasound scan. For data analyses, fetuses were categorized into preterm compromised (n = 57), preterm healthy (n = 42) and term healthy (n = 64) based on evidence of compromise at birth. Differential maturation was observed among the outcome groups. The term healthy group exhibited a body movement and, on the first stimulus trial, an FHR deceleration response at 27 weeks GA with a shift to an FHR acceleration response at 30 weeks GA. By 33 weeks GA, responding was indistinguishable from that reported for low risk fetuses with response rates of 92% for both movements and FHR accelerations. The preterm healthy outcome group showed a body movement and an FHR acceleration response at 27 weeks GA. Over gestation, there was no maturation of either response. The preterm compromised outcome group showed a body movement response at 24 weeks GA which did not mature. An FHR acceleration response was elicited at 27 weeks GA with the magnitude of the acceleration increasing over gestation; at 33 weeks GA the magnitude was below that observed in the term healthy group. With advancing gestation, the rate of cardiac–movement coupling increased only in the two healthy outcome groups. It was concluded that differential fetal behaviour as a function of fetal/newborn outcome may reflect differential functional development of the fetal nervous system.
