Maternal attachment disturbances in failure to thrive

Psychological characteristics pertaining to attachment relationships were measured in mothers of 25 hospitalized failure-to-thrive (FTT) infants and mothers of 25 hospitalized, normally growing infants. The groups were matched for race, socioeconomic status, maternal education, and infant's age and sex. Results showed that 96% of mothers of FTT infants were classified as insecure with respect to attachment, as assessed by the Adult Attachment Interview (George, Kaplan, & Main, 1985), compared to 60% of control group mothers. Lack of resolution of mourning over the loss of a loved one was found in 52% of the mothers in the FTT group and in 32% of mothers in the control group. Mothers of FTT infants reported receiving less support from their families and rated their current relationship with their partner as less satisfying. These findings provide empirical support for the widely held clinical notion that FTT in infants is often a relationship disorder between infant and caregiver.     

Fathers and fetuses

Harris postulates that in certain instances it would be morally impermissible for a woman to have an abortion because it would be a wrongful harm to the father and a violation of his autonomy. He constructs and analyzes five cases chosen to elucidate the moral issues involved and concludes that, for a man to lay claim to the fetus being his in a sense that the mother is obligated to respect, the fetus must be the result of his having pursued a legitimate interest in procreation in a morally legitimate way. When a man has satisfied the requirements of autonomy both for himself and for his sexual partner in regard to the interest in procreation, the woman has a prima facie obligation to him not to harm the fetus. Therefore, unless there is some contravening moral consideration that overrides this obligation, the abortion of the fetus is morally impermissible.     

Infant-mother attachment in children with failure to thrive

This study may represent an advance in the study of failure to thrive (FTT), as (1) it is the first to use the disorganized/disoriented classification of infant-mother attachment (Main & Solomon, 1990) in a study of children with FTT, and (2) it includes measures of social processes associated with individual differences in attachment. Twenty-six children with FTT (10 “organic,” 16 “nonorganic”) and 28 normally growing children, ages 12 to 25 months, were seen in Ainsworth's Strange Situation. The FTT and control groups were equivalent on age of mother (28.0 and 28.6 years, respectively), annual family income ($37,700 and $24,100), and mother's marital status (56% and 52% married). The sample included African-American, Caucasian, and Latino families. In addition, measures of mother-child interaction and mothers' reports of social support and life stress were included. Children with FTT were less likely to show secure and more likely to show anxious, disorganized attachments than normally growing controls: Only 35% of FTTs were secure, whereas 46% showed disorganized attachments. In contrast, 64% of controls were secure and 7% were disorganized. Comparisons between FTTs and controls also revealed differences in maternal sensitivity and stressful social environments. There were no differences in patterns of attachment, level of acute malnutrition, maternal sensitivity, social support, or life stress between organic and nonorganic FTT groups, further discrediting this as a meaningful distinction. The organic and nonorganic groups differed only on a measure of chronicity of malnutrition. These results support the notion that disrupted parent-child relationships and stressful social environments are common in FTT, regardless of the etiology of growth failure. The findings suggest that treatments of FTT must address psychological, as well as medical, problems in these families.     

Psychopathology in mothers of children with failure to thrive

An association between maternal psychopathology and failure to thrive (FTT) has been reported previously, but no prior investigators have used both operationalized diagnostic criteria for psychopathology and a control group in their studies. Twenty-eight mothers of children with FTT and 22 mothers of normally developing control children were assessed for psychopathology by the Structured Clinical Interview for DSM-III-R–Nonpatient Version (SCID-NP) and the Structured Clinical Interview for DSM-III-R–Personality Disorders (SCID-II). Affective disorders, personality disorders, and the COoccurrence in an indvidual of these two types of disorders were found at higher rates in mothers of children with FTT compared to controls. These results clarify prior reports of an association between failure to thrive and maternal psychopathology and may have implications for treatment approaches to FTT.     

Enabling diverse learners to thrive in the online homiletics classroom

Many early efforts at teaching preaching online incurred disastrous losses in quality. Revamped versions now claim to meet, and in some areas even exceed, classroom learning effectiveness, with potentially significant gains for students from non‐dominant cultures. Students preach in local ethnic and denominational contexts, so a wider range of sermon styles can flourish in indigenous soil. Students hear immediate feedback from their community, and from their online peers and professor. Online discussion formats level the playing field for non‐native speakers. By remaining embedded in their denominational and ethnic environments, student's cultural differences may be simultaneously affirmed and critiqued. This article describes capacities which predict success among preaching students, and how culture may influence the manifestation of these capacities. It details best practices and continuing challenges for professors making the transition to online preaching courses, as they seek to build culturally sustaining learning environments in which diverse students may flourish.     

Temporal pattern and spectral complexity as stimulus parameters for eliciting a cardiac orienting reflex in human fetuses

The purpose of this study was to determine whether temporal pattern and/or spectral complexity were important stimulus parameters for eliciting a cardiac orienting reflex (OR) in low-risk human fetuses. Each of 28 term fetuses was exposed to four sounds formed from the four different combinations of temporal pattern (pulsed, continuous) and spectral complexity (sine wave, /a/). The fetal cardiac electrical signal was captured transabdominally at a rate of 1024 Hz, and fetal R-waves were extracted by using adaptive signal-processing techniques. We found that pulsed sounds elicited a significantly greater decrease in heart rate (HR) than did continuous sounds. However, the HR response was relatively unaffected by spectral complexity. For the pure tone and the phoneme used in this study, our results indicate that temporal characteristics were more effective at eliciting a cardiac OR in human fetuses than was spectral complexity.     

Paternal influences in non-organic failure to thrive: Implications for psychosocial management

Clinical experience indicates that fathers have a salient influence on the development of non-organic failure to thrive (NOFT) infants and on the feeding and attachment disturbances that often accompany this pediatric condition. As shown in case examples, fathers influence the origins and outcomes of NOFT through their participation in maladaptive patterns of parenting and/or conflicts with the child's mother, which disrupt maternal emotional adjustment and maternal-child interactions. Clinical assessment of paternal influences through interview and observation can help formulate more realistic treatment planning and family-centered interventions for NOFT children.     

Habituation in normal and down's syndrome fetuses

The ability of ten normal and two Down's syndrome fetuses to habituate to a repeated auditory stimulus was assessed. The normal fetuses were assessed on two separate occasions during the final trimester of pregnancy. The number of trials to habituate and latency to respond were recorded. The results demonstrated that all normal fetuses exhibited a decrement in response to repeated presentations of the stimulus, a 250-Hz sine wave. This was the result of habituation and not fatigue since fetuses recovered responding upon presentation of a new (500 Hz) stimulus and habituated faster on re-presentation of the original stimulus. The performance of fetuses remained stable over the two testing periods. The response of the Down's syndrome fetuses was different to that of normal fetuses rarely overlapping indices of habituation exhibited by normal fetuses. The study concludes that habituation may be a powerful tool to examine the behavioural and sensory development of the fetus and may be of use in the antenatal assessment of the existence and severity of neural abnormality.     

Near-term fetuses process temporal features of speech

The perception of speech and music requires processing of variations in spectra and amplitude over different time intervals. Near-term fetuses can discriminate acoustic features, such as frequencies and spectra, but whether they can process complex auditory streams, such as speech sequences and more specifically their temporal variations, fast or relatively slow acoustic variations, is unclear. We recorded the cardiac activity of 82 near-term fetuses (38 weeks GA) in quiet sleep during a silent control condition and four 15 s streams presented at 90 dB SPL Leq: two piano melodies with opposite contours, a natural Icelandic sentence and a chimera of the sentence--all its spectral information was replaced with broadband noise, leaving its specific temporal variations in amplitude intact without any phonological information. All stimuli elicited a heart rate deceleration. The response patterns to the melodies were the same and differed significantly from those observed with the Icelandic sentence and its chimera, which did not differ. The melodies elicited a monophasic heart rate deceleration, indicating a stimulus orienting reflex while the Icelandic and its chimera evoked a sustained lower magnitude response, indicating a sustained attentional response or more focused information processing. A conservative interpretation of the data is that near-term fetuses can perceive sound streams and the rapid temporal variations in amplitude that are specific to speech sounds with no spectral variations at all.     

Treating fetuses: The patient as person

The medical treatment in utero of human beings raises several ethical questions. I argue that treatment is sufficient to establish the fetus as person; and consider how conflicts between the interests of the fetus and mother are to be resolved when such treatment is proposed. My arguments rest upon a 'relational model' of ethical discourse derived from H. Richard Niebuhr's "ethics of the fitting." I conclude that the limitation of personal autonomy is rarely justified, but may be when direct, grave, harm to others is imminent; and that educative rather than punitive measures are the best prospect for protecting fetal life.     

Aborting abnormal fetuses: the parental perspective

ABSTRACT  This paper focuses on the issue of aborting abnormal fetuses from the standpoint of the prerogatives and obligations of parents. First, two intuitively-based models of parenthood are developed. In the Trustee Model, parental authority is grounded in the obligation of parents to promote the interests of children, while the Artisan Model locates parental authority in the intrinsic value of parenthood as a mode of parental self-expression. Reasons are given for believing that neither of these models, taken individually, contains a complete or adequate picture of parenthood and that both have counterintuitive implications. Under the assumption that there is little hope of developing a master model for parenthood to supplant the two inadequate models, five principles are developed for determining how the two models should be applied in making moral decisions. These principles are then applied to five categories of abnormal fetuses. The conclusion is that abortions are justified in the first three categories (involving severe abnormalities), but not in the fifth category (involving only slight deformities). The fourth category requires parental discretion. Finally, a check on these conclusions is provided by comparing them with a parental action that would generally be considered impermissible, namely the decision of a Jehovah's Witness not to permit a blood transfusion for his or her child in a life-threatening situation.     

Habituation in normal and Down's syndrome fetuses.

The ability of ten normal and two Down's syndrome fetuses to habituate to a repeated auditory stimulus was assessed. The normal fetuses were assessed on two separate occasions during the final trimester of pregnancy. The number of trials to habituate and latency to respond were recorded. The results demonstrated that all normal fetuses exhibited a decrement in response to repeated presentations of the stimulus, a 250-Hz sine wave. This was the result of habituation and not fatigue since fetuses recovered responding upon presentation of a new (500 Hz) stimulus and habituated faster on re-presentation of the original stimulus. The performance of fetuses remained stable over the two testing periods. The response of the Down's syndrome fetuses was different to that of normal fetuses rarely overlapping indices of habituation exhibited by normal fetuses. The study concludes that habituation may be a powerful tool to examine the behavioural and sensory development of the fetus and may be of use in the antenatal assessment of the existence and severity of neural abnormality.     

An electrophysiological study of school-aged children with a history of failure to thrive during infancy

Sixty-five subjects, ages 8 to 12, participated in a visual electrophysiological study. Twenty-two of the subjects had received a diagnosis of nonorganic failure-to-thrive (FTT) before the age of three. The remaining 43 subjects had no history of FTT and served as Controls. IQs were obtained with the abbreviated WISC-III, and the Controls were split into two groups, LO IQ and HI IQ, to provide a LO IQ Control group with an average IQ equivalent to the FTT group. Event-related brain potentials (ERPs) were recorded from five scalp locations during a cued continuous performance task (CPT). Subjects had to press a button every time they saw the letter “X” following the letter “A” (50 targets out of 400 stimuli). During the CPT, the FTT subjects made marginally more errors of omission to targets than the LO IQ Control group and significantly more errors of omission than the HI IQ Control subjects. The groups did not differ significantly on errors of commission (false alarms) or reaction times to targets. ERP averages revealed a group difference in amplitude in a late slow wave for the 50 non-X stimuli (false targets) that followed the letter A. This difference was greatest over frontal sites, where the FTT group had a more negative going slow wave than each control group. Late frontal negativity to No Go stimuli has been linked with post-decisional processing, notably in young children. Thus, the FTT subjects may have less efficient inhibitory processes, reflected by additional late frontal activation. *** DIRECT SUPPORT *** A31BB040 00006

Happy people thrive on adversity: Pre-existing mood moderates the effect of emotion inductions on creative thinking

Past research on the relationship between affect and creativity has yielded contradictory results. Most of the evidence has tended to show that brief positive emotions as well as more enduring positive moods enhance creativity. No study to date, however, has attempted to determine whether the influence of momentary emotions on creativity depends on pre-existing moods. In the present study, 96 undergraduates completed one of two creative tasks (generating or evaluating captions for photographs) on three occasions, after watching videos designed to induce positive, neutral, or negative emotions. Participants also completed a questionnaire assessing depressed mood. Results confirmed that the effect of emotion inductions on creativity depended on pre-existing mood. Participants low in depression wrote more creative captions and rated captions more accurately with induced negative emotion than with induced positive emotion. In contrast, participants high in depression appeared impervious to the effect of emotion inductions.     

Young managers’ drive to thrive: A personal work goal approach to burnout and work engagement

This study approaches young managers’ occupational well-being through their work-related goal pursuit. The main aim was to identify content categories of personal work goals and investigate their associations with background factors, goal appraisals, burnout, and work engagement. The questionnaire data consisted of 747 young Finnish managers (23-35 years; M = 31 years) who were mostly men (85.5%). Seven work-related content categories were found on the basis of qualitative data analysis: (1) competence goals (30.5%), (2) progression goals (23.7%), (3) well-being goals (15.2%), (4) job change goals (13.7%), (5) job security goals (7.4%), (6) organizational goals (5.6%), and (7) financial goals (3.9%). ANCOVA analyses, where goal appraisals and significant background factors were controlled for, indicated that organizational goals were related to low burnout and the highest level of work engagement, whereas well-being and job change goals were related to higher burnout and lower work engagement. The study shows that the contents of young managers’ work-related goals can contribute to the understanding of individual differences in occupational well-being.
