Stressed parents: a dyadic perspective on perceived infant temperament

The study employed the actor–partner interdependence model (APIM) to test whether one parent's experiences of recent life events as more stressful (the PSS) are associated with the same parent's own (the actor effect) and the other parent's (the partner effect) perceptions of the infant temperament as more negatively and/or less positively tuned (the IBQ; n=584 parents, 292 dyads). The results indicated that the more stress one parent reported the more negatively tuned were the same parent's own, and the other parent's perceptions of the infant. Perceptions of the infant temperament were least positive for members of parent dyads who were more, relative to less, similar in the experienced stress. The associations were independent of the parent gender and the parent‐reported level of trait anxiety. The findings augment prior knowledge on the factors that steer parental perceptions, and suggest that the dyadic perspective may offer valuable insight into the dynamics of interacting within a family consisting of two biological parents and an infant.

面孔可爱度和客观熟悉度对婴儿面孔注意偏向效应的影响

近年来,研究发现,与成人面孔和其他社会性刺激相比,成人对婴儿面孔表现出更多的注意偏向。本研究利用点探测范式,结合眼动技术,探讨了面孔可爱度和熟悉度对婴儿面孔注意偏向效应的影响。行为结果表明,成人对高可爱度的婴儿面孔的反应时注意偏向更强;眼动结果发现,高可爱度的婴儿面孔的首注视时间偏向和总注视时间偏向更强,表现为注意维持模式,并且,这一效应只出现在低熟悉度条件下;而在可爱度评分上,高熟悉度的婴儿面孔的可爱度评分显著高于低熟悉度的婴儿面孔。结果表明,在低熟悉度条件下,可爱度才会影响成人对婴儿面孔注意偏向效应;在偏好行为上,对婴儿面孔的主观评定和观看行为上可能存在分离的情况。     

The structure of infant temperament: Factor analysis of the revised infant temperament questionnaire

Factor analyses of the Carey and McDevitt (1978) Revised Infant Temperament Questionnaire (RITQ) with a representative sample of 2,443 Australian infants provided limited empirical support for its 9-dimension structure and indicated considerable redundancy in the scale. Of the 9 dimensions, only Rhythmicity and Persistence emerged as relatively pure factors. The other factors were formed from various combinations or divisions of the dimensions. Five infant temperament factors, Approach, Rhythmicity, Cooperation/Manageability, Activity/Reactivity, and Irritability, were chosen for the development of a short form (SITQ). This short form showed good internal consistency and replicability across subsamples of the total group, A 3-factor composite scale was also developed that allowed measurement of an easy to difficult continuum that was strongly related to concurrent behavior problems. Good test-retest reliability was demonstrated for both the 5 separate scales and the composite scale. Although similarities can be shown between the SITQ and various other infant temperament scales, the SITQ has the advantages of parsimony and a firm empirical basis.     

Lip colour affects perceived sex typicality and attractiveness of human faces

The luminance contrast between facial features and facial skin is greater in women than in men, and women's use of make-up enhances this contrast. In black-and-white photographs, increased luminance contrast enhances femininity and attractiveness in women's faces, but reduces masculinity and attractiveness in men's faces. In Caucasians, much of the contrast between the lips and facial skin is in redness. Red lips have been considered attractive in women in geographically and temporally diverse cultures, possibly because they mimic vasodilation associated with sexual arousal. Here, we investigate the effects of lip luminance and colour contrast on the attractiveness and sex typicality (masculinity/femininity) of human faces. In a Caucasian sample, we allowed participants to manipulate the colour of the lips in colour-calibrated face photographs along CIELab L* (light--dark), a* (red--green), and b* (yellow--blue) axes to enhance apparent attractiveness and sex typicality. Participants increased redness contrast to enhance femininity and attractiveness of female faces, but reduced redness contrast to enhance masculinity of men's faces. Lip blueness was reduced more in female than male faces. Increased lightness contrast enhanced the attractiveness of both sexes, and had little effect on perceptions of sex typicality. The association between lip colour contrast and attractiveness in women's faces may be attributable to its association with oxygenated blood perfusion indicating oestrogen levels, sexual arousal, and cardiac and respiratory health.     

Maternal self-efficacy and experimentally manipulated infant difficulty effects on maternal sensory sensitivity: a signal detection analysis

The impact of differences in maternal self-efficacy and infant difficulty on mothers' sensitivity to small changes in the fundamental frequency of an audiotaped infant's cry was explored in 2 experiments. The experiments share in common experimental manipulations of infant difficulty, a laboratory derived measure of maternal efficacy (low, moderate, and high illusory control), and the use of signal detection methodology to measure maternal sensory sensitivity. In Experiment 1 (N = 72), easy and difficult infant temperament was manipulated by varying the amount of crying (i.e., frequency of cry termination) in a simulated child-care task. In Experiment 2 (N = 51), easy and difficult infant temperament was manipulated via exposure to the solvable or unsolvable pretreatment of a learned helplessness task to mirror mothers' ability to soothe a crying infant. In both experiments, only mothers with high illusory control showed reduced sensory sensitivity under the difficult infant condition compared with the easy infant condition.     

The listener's temperament and perceived tempo and loudness of music

The relationship between the listener's temperament and perceived magnitude of tempo and loudness of music was studied using the techniques of magnitude production, magnitude estimation scaling and cross‐modal matching. Four piano pieces were presented at several levels of tempo and loudness. In Study 1, participants adjusted tempo and loudness of music to their subjective level of comfort. In Study 2, participants estimated these parameters on a numerical scale and matched the length of a line segment to the estimates of these musical features. The results showed significant correlations of selected aspects of perceived tempo with perseveration and endurance as well as of selected aspects of perceived loudness with endurance and emotional reactivity. Perceived tempo and loudness, as measured by magnitude production and cross‐modal matching tasks, do not seem to systematically correlate with the six formal characteristics of behaviour distinguished in the most recent version of the Regulative Theory of Temperament (RTT). Additionally, there is some evidence that they are selectively associated with reactivity and activity, the dimensions of a previous version of the RTT. The study extends the methodology of research on music preferences and the stimulatory value of music. Copyright © 2009 John Wiley & Sons, Ltd.     

Relating early child adjustment to infant and parent temperament

The central question at issue was the role of both infant and parent temperament in determining child adjustment at age 4. Within the conceptual framework of the New York Longitudinal Study (NYLS), both infant and parent temperament were assessed. Factor analyses yielded three comparable infant and parent temperament factors: Mood, Energy, and Consistency. Correlations with teacher ratings of child adjustment indicated the most significant relationship to be with the infant girls' Mood factor (comparable to the NYLS high-risk "difficult" infant factor). No infant factors were found to relate to boys' adjustment, while maternal Mood was significant across sexes. Indices of the temperamental similarity within families also revealed sex differences relative to adjustment, with similarity across all family members significantly related to adjustment for girls and boy-father dissimilarity significant for boys. Discussion centered around continuity-discontinuity issues relevant to sex differences.     

The association of paternal mood and infant temperament: A pilot study

Maternal depression is associated with adverse child development, but little is known about the effects of paternal depression. This pilot study estimated the prevalence of paternal depression and mood state, and assessed the relationship between paternal mood and infant temperament. The participants in the study were 98 fathers of newborn babies. Fathers were initially screened for depressed mood (Hospital anxiety and depression scale, and Edinburgh postnatal depression scale), and at 6 months parental mood, infant temperament, couple relationship quality, alcohol use, adverse life events, parenting, and demographics were recorded. Infant fussiness was analysed in relation to paternal mood and other contextual factors using multiple regression. Of the 98 fathers, 48 (49%) completed depression-screening measures. Of these 48 fathers, 4 (8%) reported depressive symptoms above the cut-off for case definition. A total of 48% (N=19) completed measures at follow-up. In the adjusted model, higher paternal depression scores, more traditional attitudes towards fathering, and increased recent life events were related to higher infant fussiness scores; and better couple relationship quality was related to lower fussiness scores. This study showed that 1 in 12 fathers had depressed mood, and lower mood was associated with negative infant temperament. Since the findings of this feasibility study were based on a small sample size the association of paternal mood and child development merits further study using a larger sample of fathers.     

The influence of gender and temperament on children's interaction with a baby

This study examined gender differences in children's interaction with a baby who visited their day-care center over several weeks. Twenty-two children ranging in age from 47 to 64 months of age participated. The children's teacher filled out a questionnaire assessing each child's extraversion, activity level, and loudness. A female baby visited the day care center from one to three times a week over a two-month period. Each child's interactions with the baby were observed twice. Active, outgoing, loud girls were much more likely to interact with the baby than either quiet girls or any boys. Several of these highly interactive girls had no younger siblings. Children were found to interact with the baby more on their second observation.The research reported here was supported by a grant from the Purdue Research Foundation.

Perceived infant temperament,locus of control,and maternal physiological response to infant gaze

Maternal physiologic response was used as an index of maternal attention to infant eye contact. Thirty-six women, each of whom had a 3-month-old infant, were shown 10-sec silent images of a 3-month-old infant on a videotape monitor. In one condition the en face position offered eye contact, in the other condition eye contact was not possible. Each woman viewed a sequence of six identical episodes of one condition followed by six episodes of the other condition. Heart rate and skin conductance were recorded continuously during the session. Skin conductance response did not differentiate between reciprocated and unreciprocated gaze. Cardiac response elicited by reciprocated gaze viewed first shifted from a predominately orienting response on early trials to an acceleratory response on Trial 6. The acceleratory response was most pronounced in those women identified as Externals by the Locus of Control Inventory (Rotter, J. B. Psychological Monographs, 1966, 80, [No. 609]). Initial viewing of the infant looking away elicited a predominantly deceleratory heart-rate response that did not habituate. Mothers who described their infants as being difficult as assessed by the questionnaire method (Carey, W. B. Journal of Pediatrics, 1970, 77, 188–194) were physiologically less sensitive to the change from the infant's averted gaze to its direct gaze. Results are discussed in terms of the role of direct and averted gaze during social transactions.     

Expectation and temperament moderate amygdala and dorsal anterior cingulate cortex responses to fear faces

A chronic tendency to avoid novelty is often the result of a temperamental bias called inhibited temperament, and is associated with increased risk for anxiety disorders. Neuroimaging studies have demonstrated that an inhibited temperament is associated with increased amygdalar blood-oxygenation-level-dependent (BOLD) response to unfamiliar faces that were not expected; however, the effects of variations in expectancy remain unknown. Using functional magnetic resonance imaging (fMRI), we studied BOLD response to infrequently encountered fear faces that were either expected or not expected in 42 adults with an inhibited or an uninhibited temperament. Individuals with an inhibited temperament had greater amygdala, but less dorsal anterior cingulate cortex (dACC), BOLD response when the stimuli were expected. In contrast, those with an uninhibited temperament had a smaller amygdala but larger dorsal anterior cingulate cortex BOLD response when expecting to see fear faces. These findings demonstrate temperament differences in expectancy effects and provide preliminary evidence for the dACC as a neural substrate mediating differences in inhibited temperament. Enhanced amygdala sensitivity coupled with weak inhibitory control from the dACC may form a neural circuit mediating behaviors characteristic of inhibited temperament and risk for anxiety disorders.     

Paternal influences on infant temperament: Effects of father internalizing problems,parenting-related stress,and temperament

Temperament ratings were obtained from 98 fathers when their infants were 4 and 6 months of age to examine effects of paternal characteristics on infant temperament. Parental stress, internalizing symptoms, and father's temperament were considered as factors possibly contributing to differences in their child's temperament.     

Mind the baby: The role of the nanny in infant observation

The influence of nannies and other significant caregivers on a child's psychological and emotional development may be profound and if unrecognized may contribute to psychopathology in adulthood. However, the significance of the nanny has been relatively neglected within the psychoanalytic literature. In this paper I will discuss the impact of early caregivers other than the biological mother on the psychic development of the child, and the role of the nanny within the family dynamics as a figure attracting powerful unconscious phantasies and unwanted projections. These ideas will be illustrated by a detailed account of a year‐long observation of an infant who had a succession of several different nannies in her first three months before her parents employed a more permanent nanny. It is proposed that the baby's emerging attachments to her two primary caregivers, mother and nanny, developed in parallel and influenced each other, with observable impact on her behaviour and developing personality. The paper concludes with a review of the place of infant observation within psychoanalytic training and how the experience of witnessing the earliest infant‐caregiver relationships in an extra‐analytic setting both refines understanding of developmental theory and builds a foundation for psychoanalytic practice.     

Variation in perceived attractiveness: differences between dynamic and static faces

Studies that attempt to define facial attractiveness often do so in terms of structural features of the face (e.g., symmetry, averageness). However, these studies typically use static images of faces that may not be analogous to dynamic faces that are frequently used in other areas of attractiveness research, such as research investigating the impact of attractiveness on social interaction. The current studies investigated similarities and differences in how dynamic and static faces are perceived and evaluated. Study 1 demonstrated that dynamic and static faces are judged by different evaluative standards. Study 2 demonstrated that perceived emotion may be more salient in judging the attractiveness of dynamic faces than in judging the attractiveness of static faces. These findings illustrate the need to more fully explore the differences between dynamic and static faces to facilitate a better understanding of the characteristics underlying perceived attractiveness.     

From early withdrawal reaction to infant depression: A baby alone does exist

Despite the frequent use of the term and although it is a key notion in evaluation, infant depression remains poorly defined and assessed since the initial work of René Spitz. This paper reviews recent aspects of infant depression related to classification, issues in infancy, attachment disorders, relationship disorders, maternal depression, failure to thrive and protein energy malnutrition. The actual scope of depression might include some aspects of protein energy malnutrition, a frequent and severe disease in tropical and developing countries, and some aspects of failure to thrive as observed in some multi-problem families in western countries. There might be a continuum between withdrawal reaction and infant depression. Withdrawal reaction is observed in various organic or psychopathological conditions, and could be used as an alarm symptom to screen infants in well-baby clinics. Infant depression is difficult to recognize, and delay in its recognition may have important developmental consequences. © 1997 Michigan Association for Infant Mental Health
