Psychological symptoms and competence at three organizational levels of industrial design: the main and moderating role of sense of coherence

This study investigated the role of the sense of coherence in occupational well-being at three organizational positions of industrial designing (top-level designers, designers, and assisting personnel). In a sample of 422 industrial design personnel, sense of coherence was positively related to competence and negatively to psychological symptoms. It also moderated the relation of autonomy to competence and psychological symptoms but more strongly among the designers and the assisting personnel than among the top-level designers. Analysis showed autonomy was beneficial for individuals who also had high scores on sense of coherence. Longitudinal studies are needed on the role of sense of coherence as regards the psychological health of different subgroups.     

Maternal representations and emotional availability among drug‐abusing and nonusing mothers and their infants

Both negative and idealized maternal prenatal representations may constitute a risk for mother–infant interaction. This study analyzed the role of maternal prenatal representations and pre‐ to postnatal representational change in predicting mother–infant emotional availability (EA) among 51 drug‐abusing mothers and their infants who participated in either psychodynamic group therapy (PGT) or received psychosocial support (PSS) and among 50 nonusing comparison dyads. Maternal representations of her child, the child's father, her own mother, self‐as‐mother, and self‐as‐woman were measured during pregnancy and at 4 and 12 months' postpartum with the Interview of Maternal Representations (M. Ammaniti et al., 1992 ; M. Ammaniti, R. Tambelli, & P. Perucchini, 1998). EA was measured with the Emotional Availability Scales, fourth edition (Z. Biringen, 2008 ) at 4 and 12 months. The results showed that drug‐abusing mothers had more negative prenatal representations of the self‐as‐woman and of the child's father. Postnatally, PSS mothers tended to first idealize their child, but later to experience disillusionment of idealization. Both negative and idealized prenatal representations of the self‐as‐mother predicted mother–infant EA problems, but only among the PGT mothers. For all mothers, negative representational change was detrimental for the mother–infant EA whereas for drug‐abusing mothers, also increasing idealization from the prenatal period to the postnatal period was harmful. Clinicians working with drug‐abusing mothers should aim at supporting the development of a realistically positive view of motherhood.     

MATERNAL TRAUMA AFFECTS PRENATAL MENTAL HEALTH AND INFANT STRESS REGULATION AMONG PALESTINIAN DYADS

We examined how diverse and cumulated traumatic experiences predicted maternal prenatal mental health and infant stress regulation in war conditions and whether maternal mental health mediated the association between trauma and infant stress regulation. Participants were 511 Palestinian mothers from the Gaza Strip who reported exposure to current war trauma (WT), past childhood emotional (CEA) and physical abuse, socioeconomic status (SES), prenatal mental health problems (posttraumatic stress disorder and depression symptoms), and perceived stress during their secondtrimester of pregnancy as well as infant stress regulation at 4 months. While all trauma types were associated with high levels of prenatal symptoms, CEA had the most wide‐ranging effects and was uniquely associated with depression symptoms. Concerning infant stress regulation, mothers’ CEA predicted negative affectivity, but only among mothers with low WT. Against hypothesis, the effects of maternal trauma on infant stress regulation were not mediated by mental health symptoms. Mothers’ higher SES was associated with better infant stress regulation whereas infant prematurity and male sex predisposed for difficulties. Our findings suggest that maternal childhood abuse, especially CEA, should be a central treatment target among war‐exposed families. Cumulated psychosocial stressors might increase the risk for transgenerational problems.     

APPARENT WEIGHT DIFFERENCES AS A SOURCE OF AFTER-EFFECTS

Two experiments are reported. In the first, the influence of stimulus size on apparent weight, i.e., the size-weight illusion, was scaled. The relationship between heaviness and size could be described by a simple power function. In the second experiment it was demonstrated that the illusory weight differences give rise to aftereffects. The size of the after-effect increased monotonically with the amount of apparent weight difference.
