Different coordination and flexibility of the spine and pelvis during lateral bending between young and older adults

This study examined coordination of the spine and pelvis during lateral bending of the trunk in older adults. Thirty-four healthy subjects (17 young and 17 older adults) demonstrated lateral bending at a controlled speed while holding a bar at approximately 180 degrees of shoulder flexion. Kinematic data collection was completed on the thoracic spine, lumbar spine, and pelvis. The coupling angle was calculated to examine the thorax–lumbar, lumbar–pelvis, and thorax–pelvis coordination patterns. The older adults demonstrated a reduced range of motion (ROM) of the lumbar spine, while both groups revealed similar ROM in the thorax and in the pelvis. The coupling angle between the straightening and bending phases was different only for the older adults in the thorax–lumbar (23.4 ± 8.0 vs. −1.6 ± 4.4, p = 0.004) and the lumbar–pelvis (65.4 ± 7.2 vs. 86.1 ± 7.8, p = 0.001) coordination. However, there was no group difference in the thorax–pelvis coordination. These findings indicate that age-related changes in the lumbar region affect coordination patterns only during the bending phase. The older adults preserved a similar pattern of movement to the young adults during the straightening phase, but the coordination variability of the coupling angles was greater for the older adults than for the young adults. This movement pattern suggests that the older adults lacked consistent trunk control in an attempt to optimize lateral bending coordination.     

Effect of consonant/vowel letter organisation on the syllable counting task: evidence from English

Recent studies in alphabetic writing systems have investigated whether the status of letters as consonants or vowels influences the perception and processing of written words. Here, we examined to what extent the organisation of consonants and vowels within words affects performance in a syllable counting task in English. Participants were asked to judge the number of syllables in written words that were matched for the number of spoken syllables but comprised either 1 orthographic vowel cluster less than the number of syllables (hiatus words, e.g., triumph) or as many vowel clusters as syllables (e.g., pudding). In 3 experiments, we found that readers were slower and less accurate on hiatus than control words, even when phonological complexity (Experiment 1), number of reduced vowels (Experiment 2), and number of letters (Experiment 3) were taken into account. Interestingly, for words with or without the same number of vowel clusters and syllables, participants’ errors were more likely to underestimate the number of syllables than to overestimate it. Results are discussed in a cross-linguistic perspective.     

A Review and Taxonomy of Choice Architecture Techniques

We present a taxonomy of choice architecture techniques that focus on intervention design, as opposed to the underlying cognitive processes that make an intervention work. We argue that this distinction will facilitate further empirical testing and will assist practitioners in designing interventions. The framework is inductively derived from empirically tested examples of choice architecture and consists of nine techniques targeting decision information, decision structure, and decision assistance. An inter‐rater reliability test demonstrates that these techniques can be used in an intersubjectively replicable way to describe sample choice architectures. We conclude by discussing limitations of the framework and key issues concerning the use of the techniques in the development of new choice architectures.

Timing of Early Maternal Mental Health and Child Cortisol Regulation

Maternal mental health problems can negatively impact children's physiological stress regulation. Yet, little is known of their long‐term effects, especially related to the timing of maternal symptoms. We examined how maternal mental health problems during pregnancy versus in the early postpartum period predict children's cortisol levels and diurnal patterns at 10–12 years. Participants were a selection (N = 102) of an original sample of 805 Finnish families, who were followed from the second trimester of pregnancy (T1) to child's age of 2 months (T2) and 12 months (T3), and again at child's age of 10–12 years (T4). Based on the timing of psychological distress and depressive symptoms (T1–T3), the mothers could be assigned to three distinct mental health trajectory groups: mothers with prenatal mental health problems (n = 15), mothers with early postpartum mental health problems (n = 15) and mothers without mental health problems (n = 72). Children's cortisol (T4) was measured by saliva samples through five within‐1‐day assessments. The results show that maternal prenatal mental health problems predicted a relatively steep increase of child cortisol from awakening to 1 h later, indicating an intensified cortisol awakening response (CAR). Mothers' early postpartum mental health problems instead predicted a reduced CAR. Both maternal prenatal and postnatal mental health problems thus predicted children's later stress regulation, but in unique ways. We discuss the specific roles of direct biochemical effects during pregnancy and postpartum mother–infant interaction quality as modifiers of the hypothalamic–pituitary–adrenal system.

Thinking about seeing: Perceptual sources of knowledge are encoded in the theory of mind brain regions of sighted and blind adults

Blind people’s inferences about how other people see provide a window into fundamental questions about the human capacity to think about one another’s thoughts. By working with blind individuals, we can ask both what kinds of representations people form about others’ minds, and how much these representations depend on the observer having had similar mental states themselves. Thinking about others’ mental states depends on a specific group of brain regions, including the right temporo-parietal junction (RTPJ). We investigated the representations of others’ mental states in these brain regions, using multivoxel pattern analyses (MVPA). We found that, first, in the RTPJ of sighted adults, the pattern of neural response distinguished the source of the mental state (did the protagonist see or hear something?) but not the valence (did the protagonist feel good or bad?). Second, these neural representations were preserved in congenitally blind adults. These results suggest that the temporo-parietal junction contains explicit, abstract representations of features of others’ mental states, including the perceptual source. The persistence of these representations in congenitally blind adults, who have no first-person experience with sight, provides evidence that these representations emerge even in the absence of relevant first-person perceptual experiences.     

The spatial metaphor of Utopia in Russian culture and in analysis

The spatial metaphor of Utopia is considered from a Jungian perspective along with its role in Russian culture and in analysis. Such post‐Jungian concepts as the cultural complex and the archetypal story pattern of a victim are used in considering the desperate longing for a rescuer in patients' narratives and in Russian society. A clinical vignette is provided to illustrate these ideas.     

Childhood experiences of parental rearing patterns reported by Chinese patients with borderline personality disorder

The primary purposes of this study were to (1) compare the characteristics of childhood experiences of parental rearing patterns in China reported by patients with borderline personality disorder (BPD), patients with other personality disorders and patients without personality disorders; (2) identify the reported parental rearing patterns associated with BPD in China; and (3) determine whether these patterns differ for males and females. One hundred and fifty‐two patients with BPD, 79 patients with other personality disorders and 55 patients without Axis II diagnoses were administered the Chinese version of the McLean Screening Instrument for BPD and completed the Egna Minnen av Barndoms Uppfostran (EMBU), a self‐report measure of childhood parental rearing patterns. Parental rearing patterns reported by the BPD group were characterized by less emotional warmth, and greater punishment, rejection and control than patterns reported by the other two groups. Within the BPD group, males were more likely than females to report parental punishment, rejection and control. Paternal punishment, low maternal emotional warmth and female gender predicted BPD diagnosis. Negative parental rearing patterns appear to contribute to the development of BPD in China and vary with the gender of the child. Maternal emotional warmth may be a protective factor against BPD.
