The effects of work- and family-related transitions on young people’s perception of being adult

Using a nationwide sample of 2656 eighteen- to twenty-nine-year-olds, the first part of the present study addressed the question of how non-traditional as compared to traditional living arrangements related to young people’s self-perception of being either adolescent or adult. Being in a romantic relationship increased the likelihood of feeling adult. Modern adult living arrangements (living alone in a single household or sharing an apartment with peers) increased the likelihood of feeling adolescent. Employing a longitudinal sample of 461 twenty- to twenty-seven-year-olds, changes in job status and sources of income were studied with regard to their connections to the emergence of subjective adulthood or the regression to subjective adolescence, respectively. No association between adult or adolescent self-perception and issues of work and material autonomy was found, but the emergence of subjective adulthood was related to romantic relationships and parenthood. Findings are discussed with reference to young people’s volatile living conditions and transient commitments implied by social change.     

The Michigan infant mental health home visiting model

Selma Fraiberg's pioneering work with infants, toddlers, and families over 40 years ago led to the development of a field in which professionals from multiple disciplines learned to work with or on behalf of infants, very young children, their parents, and the relationships that bind them together. The intent was to promote social and emotional health through enhancing the security of early developing parent–child relationships in the first years of life (Fraiberg, 2018). Called infant mental health (IMH), practitioners from fields of health, education, social work, psychology, human development, nursing, pediatrics, and psychiatry specialize in supporting the optimal development of infants and the developing relationship between infants and their caregivers. When a baby is born into optimal circumstances, to parents free of undue economic and psychological stressors and who are emotionally ready to provide care and nurturing for an infant's needs, an IMH approach may be offered as promotion or prevention, with the goal of supporting new parent(s) in developing confidence in their capacity to understand and meet the needs of the tiny human they are coming to know and care for. However, when parental history is fraught with abandonment, loss, abuse or neglect, or the current environment is replete with economic insecurity, threats to survival due to interpersonal or community violence, social isolation, mental illness, or substance abuse, the work of the IMH therapist may require intervention or intensive treatment and becomes more psychotherapeutic in nature. The underlying therapeutic goal is to create a context in which the baby develops within the environment of a parent's nurturing care without the psychological impingement that parental history of trauma or loss or current stressors such as isolation, poverty, or the birth of a child with special needs, can incur.     

The Adjustment Process of Ex-Buddhist Monks to Life After the Monastery

This study explores the adjustment process of five Western ex-Buddhist monks to life after the monastery, using an in depth case study approach and thematic analysis. Participants discussed their initial experience of leaving, the process of creating a new life and their relationship with the past. The findings indicated that while each case was unique, significant common themes emerged as features of the adjustment process. The adjustment had been multi-dimensional, challenging, difficult, confusing, complex and profound for the participants. They had to contend with issues of grief, delayed development, missing out on life experiences, difficulties with intimacy, money, identity, depression, anxiety and confusion. This was combined with the hope and promise of many newly found freedoms involved in establishing a new life and identity. Parallels are drawn to the experience of Catholic priests and nuns who have departed their Orders, Vietnam veterans, ex-cult members and individuals who have left total institutions where their identity and daily lives were highly prescribed. The adjustment experience of ex-Buddhist monks extends the literature on Buddhist monks and provides an example of a life transition of interest to the helping professions because of its potential relevance to a range of major transitions for which clients may seek assistance.

Arrows of time in infancy: the representation of temporal-causal invariances

Many transformations that take place over time can only occur in one temporal direction, and adults are highly sensitive to the differences between forward and backward presentations of such events. In seven experiments using two selective-looking paradigms, 4- and 8-month-olds were shown forward and backward videotapes of events involving the effects of gravity on liquids and solid objects and of the separation of whole objects into pieces. Four-month-olds showed a significant preference for the forward version of liquid pouring from a beaker to a glass. Eight-month-olds looked longer at the forward versions of this and four other gravity-related events but showed no directional preferences for the separation events. Several experiments indicate that longer looking at the forward versions of the gravity stimuli is not a product of attraction to specific perceptual features of the stimuli. A model based on the development of representations of types of events is presented and evaluated.     

The rooting reflex as an infant feeding cue

Experts in infant health and development consider the rooting reflex a cue of a baby's hunger and recommend feeding the infant when this reflex occurs. However, the relation between rooting and infant feeding status has not been well established in the literature. In the current study, seven parents documented the occurrence of their newborns' rooting, crying, and a control reflex (palmar grasp) before, after, and between naturally occurring feedings. For all participants, rooting occurred during a greater percentage of reflex checks prior to feedings, whereas the palmar grasp occurred during a similar percentage of checks across these time periods. These results provide empirical support for the rooting reflex as a feeding cue. However, data for only one dyad suggested a high probability of the rooting reflex occurring without crying during prefeeding checks. Thus, our data do not provide evidence that feeding in response to the rooting reflex would preempt infant crying.     

Sex Differences in Mothers' Speech and Play Behavior with 6-, 9-, and 14-Month-Old Infants

In this study, we analyzed mothers' speech and play behavior with their 6-, 9-, and 14-month-old sons and daughters. Thirty-six infant–mother dyads participated in a 10-min free-play session with gender-neutral toys. No sex differences were found in the infants' behavior, but sex differences were found in mothers' verbal behavior and level of engagement. Mothers of daughters made more interpretations and engaged in more conversation with their daughters, whereas mothers of sons made more comments and attentionals, which were typified by instructions rather than conversation. Furthermore, mothers interacted more with their daughters than with their sons across all ages. Overall, these results demonstrate that mothers transmit different messages to their male and female infants, both through language and interaction, which may contribute to infants' gender role development.     

Infant placement and language exposure in daily life

Children's daily contexts shape their experiences. In this study, we assessed whether variations in infant placement (e.g., held, bouncy seat) are associated with infants' exposure to adult speech. Using repeated survey sampling of mothers and continuous audio recordings, we tested whether the use of independence-supporting placements was associated with adult speech exposure in a Southeastern U.S. sample of 60 4- to 6-month-old infants (38% male, predominately White, not Hispanic/Latinx, from higher socioeconomic status households). Within-subject analyses indicated that independence-supporting placements were associated with exposure to fewer adult words in the moment. Between-subjects analyses indicated that infants more frequently reported to be in independence-supporting placements that also provided posture support (i.e., an exersaucer) were exposed to relatively fewer adult words and less consistent adult speech across the day. These findings indicate that infants' opportunities for exposure to adult speech ‘in the wild’ may vary based on immediate physical context.     

Infants’ coding of location in continuous space

The ability to code location in continuous space is fundamental to spatial behavior. Existing evidence indicates a robust ability for such coding by 12 months, but systematic evidence on earlier origins is lacking. A series of studies investigated 5-month-olds’ ability to code the location of an object hidden in a sandbox, using a looking-time paradigm. In Experiment 1, after familiarization with a hiding-and-finding sequence at one location, infants looked longer at an object being disclosed from a location 12 inches (30 cm) away than at an object emerging from the hiding location, showing they were able to code location in continuous space. In Experiment 2, infants reacted with greater looking when objects emerged from locations 8 inches (20 cm) away from the hiding location, showing that location coding was more finely grained than could be inferred based on the first study. In Experiment 3, infants were familiarized with an object shown in hiding-and-finding sequences at two different locations. Infants looked longer at objects emerging 12 inches (30 cm) away from the most recent hiding location than to emergence from the other location, showing that infants could code location even when events had previously occurred at each location. In Experiment 4, after familiarization with two objects with different shapes, colors, and sounding characteristics, shown in hiding-and-finding sequences in two locations, infants reacted to location violations as they had in Experiment 3. However, they did not react to object violations, that is, events in which the wrong object emerged from a hiding location. Experiment 5 also found no effect of object violation, even when the infants initially saw the two objects side by side. Spatiotemporal characteristics may play a more central role in early object individuation than they do later, although further study is required.     

The Development of Infants' Spatial Categories

ABSTRACT— Early theories of how infants develop spatial concepts focused on the perceptual and cognitive abilities that contribute to this ability. More recent research, however, has centered on whether experience with spatial language might also play a role. The present article reviews how infants learn to form spatial categories, outlining the perceptual and cognitive abilities that drive this learning, and examines the role played by spatial language. I argue that infants' spatial concepts initially are the result of nonlinguistic perceptual and cognitive abilities, but that, as infants build a spatial lexicon, spatial language becomes an important tool in the spatial categories infants learn to form.     

Giant electrocaloric effect of highly (1 0 0)-oriented 0.68PbMg1/3Nb2/3O3–0.32PbTiO3 thin film

PbZr_0.95Ti_0.05O₃ thin film has the highest electrocaloric properties of all the oxide thin films (0.48?K?V^?1). Here, it is shown giant electrocaloric properties in 200?nm (1?0?0)-oriented PMN–PT 68/32 film near the ferroelectric Curie temperature of 146?°C. The results indicate the significance of this system to achieve electrocaloric entropy change and temperature change, up to 32.21?J/kg?°C and 14?K, respectively, in 12?V (i.e. 1.155?K?V^?1) near the Curie point. This exceeds the previous best results obtained in PbZr_0.95Ti_0.05O₃ thin film.     

Infant temperament and performance on the Bayley Scales of Infant Development at 4, 8, and 12 months of age

Infants were assessed with the Rothbart Infant Behavior Questionnaire (an objective measure of infant temperament based on maternal reports) and the complete Bayley Scales of Infant Development (BSID) at 4, 8, and 12 months of age. Activity level was related to BSID performance at each age with babies who obtained higher scores rated as more active. Activity level was also related to the infants' behavior during the test administration at 8 and 12 months. A negative relation was found between smiling and laughter and the mental development index at 8 and 12 months. These data suggest that aspects of infant temperament as assessed by maternal report share a small amount of variance with BSID performance and the amount of shared variance increases with age.     

The effects of antecedent interventions and extinction on toddlers' compliance during transitions

We compared the effects of two antecedent strategies commonly used in early childhood settings to increase compliance during activity transitions: a warning condition, in which children were informed of the transition 2 min before it began, and a condition in which children were allowed access to a toy during the transition. Both antecedent interventions were ineffective when implemented alone; however, when these strategies were combined with extinction, improvements in compliance were observed for all children.     

Mathematical Models of Central Pattern Generators in Locomotion

Possible neural connective patterns and functions with respect to interlimb coordination are studied theoretically with a mathematical model of the central pattern generating system for cat locomotion. Activities in populations of neurons controlling limb joint flexors and extensors in all four limbs are represented by a system of nonlinear differential equations. Solutions of the system for various parameter values simulate various gaits of the cat. The model is shown to be capable of generating all gaits of the cat and accounting for corresponding phase changes in interlimb coordination. The model also exhibits smooth changes of gait, and smooth initiation and termination of stepping. Further, within each limb, muscle sequencing, step cycle phases, and flexor-extensor interactions can be studied. The model suggests that one of the simplest mechanisms for a central command system to change the gait is via inhibition of specific interlimb propriospinal pathways. In a final section, properties of both proposed single limb and interlimb models are reviewed with specific reference to planning future experimental and theoretical studies.     

The role of speed and incline in the spontaneous choice of technique in classical roller-skiing

Cross-country skiers change technique depending on terrain (incline) and effort (work rate; speed at a particular incline or resistance). The literature is not unequivocal about the influence of incline or speed on the choice of technique, i.e., which of these act as a ‘control parameter’. Identifying task related control parameters for spontaneous technique shifts assists elucidating which mechanisms are active for triggering technique transitions. The aim of this study was to investigate whether speed or incline acted as such control parameter for technique shifts during classic style roller skiing. In this study, we kept the exercise intensity constant while changing two potential control parameters (speed and incline). Thus, any effect of work rate was excluded.Eight male competitive cross-country skiers performed roller skiing on a treadmill while incline was altered from 3 to 11% and back to 3% each minute by 1% and speed changed accordingly to obtain a constant work rate. This protocol was performed at three submaximal work rates (170, 200, and 230 W) to obtain various combinations of speed and incline.The athletes were free to choose their technique (double poling, double poling with kick and diagonal stride), which was identified using continuous phase analysis on the motion of the skis. Physiological response (heart rate, oxygen uptake) was recorded continuously.The incline seemed to affect choice of technique shift more than speed: the ANOVA for repeated measures on all work rates showed no significant effect of incline (p > 0.2) and an effect for speed (p < 0.001). No effect of protocol order (increasing versus decreasing incline) was found for transitions. The physiological response was lowest for conditions of steep incline-low speed and was affected by protocol order. Cycle rate was affected by incline only in the double poling technique.Possible mechanisms related to the triggering of technique transitions are discussed.     

Semiotic transformations in psychoanalysis with infants and adults

The author addresses issues that emerge when we compare psychoanalytic experiences with adults and with infants. Two analyses-one with a 35 year-old woman and one with a 2 week-old boy and his mother-illustrate that infant psychoanalytic experiences help us understand and handle adult transference. However, we cannot extrapolate infant experiences to adult work. Truly, witnessing the baby's communication widens our sensitivity to non-verbal layers of the adult's communication. Infant work also offers a direct encounter with the container and the contained personified by a mother with her baby. But we need to conceptualize carefully the links between clinical experiences with babies and adults. When we call an adult transference pattern 'infantile', we imply that primeval experience has been transformed into present behaviour. However, if we view the analytical situation as one in which infantile invariants have transformed into adult symptoms, we face the impossible task of indicating the roots of the present symptoms. The author rather suggests that what is transformed is not an invariant infantile essence but signs denoting the patient's inner reality. He proposes we define transformation as a semiotic process instead of building it on an essentialist grounding. If we view the analytic situation as a map of signs that we translate during our psychoanalytic work, we can proceed into defining containment as a semiotic process. This idea will be linked with a conceptualization of the mother-infant relation in semiotic terms.     

The development of infants' preference for motherese

Generally, infants prefer infant-directed (ID) to adult-directed (AD) speech. Mostly, researchers have used unfamiliar female voices in these studies. We investigated preferences for maternal ID speech in 1- and 4-month-olds. Using a procedure in which infants controlled access to voices by fixating a visual display, infants listened to recordings of natural female ID and AD speech. In Experiment 1, 1-month-olds heard recordings of maternal ID and AD speech, but these infants showed no preference for maternal ID speech. In Experiment 2, 1-month-olds heard the same ID and AD speech tapes but were not familiar with the speakers. Contrary to Experiment 1, these infants preferred ID speech. In Experiment 3, 4-month-olds heard recordings of maternal ID and AD speech and showed a significant preference for ID speech. Collectively, these results suggest that infant attention to ID speech depends on both speaker-general and speaker-specific characteristics, with interesting developmental changes occuring during early infancy.     

Expectations and perceptions at school transitions: The role of peer status and aggression

This study integrated research on aggression, peer status, and social and academic functioning across the middle- and high-school transitions. We examined how peer status and aggression are related to adolescents' expectations about their academic and social functioning in a new school system before the transition into that system, and their perceived academic and social functioning after the transition. Social preference, perceived popularity, overt and relational aggression, and social and academic expectations were assessed in Grades 5 and 8; identical peer status and aggression constructs and perceived social and academic functioning were assessed in Grades 6 and 9. Results indicated moderate correlations between adolescents' social and academic expectations and perceived functioning across both school transitions. Girls reported higher social and academic functioning than boys did in most cases. Perceived popularity was consistently positively associated with academic and social expectations for middle and high school, whereas social preference was associated with perceived social functioning in both middle school and high school. The link between aggression and outcome variables varied by age and was moderated by gender and peer status.
