Can but don’t: olfactory discrimination between own and alien offspring in the domestic cat

Mammalian maternal care usually comes at a large energetic cost. To maximize their fitness, mothers should preferentially care for their own offspring. However, the majority of studies of mother–offspring recognition have focused on herd- or colony-living species and there is little information on maternal discrimination in more solitary-living species. Olfaction has been found to play a major role in mother–offspring recognition across various taxa. Therefore, our aim was to study this in a species evolved from a solitary-living ancestor, the domestic cat. We asked whether cat mothers distinguish between their own and alien offspring when providing maternal care, and whether cat mothers use olfactory cues in the offspring discrimination process. Results of Experiment 1 showed that cat mothers do not discriminate between own and alien young when retrieving them to the nest. They treated own and alien young similarly with respect to latency and order of retrieval. However, the results of Experiments 2 and 3, where we used an olfactory habituation-discrimination technique, showed that mothers were able to distinguish between the odours of their own and alien kittens. We discuss what ecological and/or behavioural factors might influence a mother’s decision when faced with discriminating between own and alien young, and why mothers might not discriminate between them when they are able to do so. Our findings support the view that maternal care alone should not be used as a measure of offspring recognition, and equal maternal care of own and alien young should not be immediately interpreted as an inability to discriminate between them.     

Teacher Job Stress and Satisfaction in Urban Schools: Disentangling Individual-, Classroom-, and Organizational-Level Influences

Schools remain among the most frequent providers of children’s mental health services, particularly in low-income urban settings. Several decades of research have focused on training teachers to implement evidence-based interventions for minimizing disruptive behavior. Studies consistently demonstrate robust improvements in student behavior and learning; however, the impact on teachers’ work-related stress or satisfaction is not well understood. Six urban, high-poverty elementary schools were randomly assigned to a school mental health services model (Links to Learning; L2L) for referred, disruptive students or to services and professional development as usual (SAU). Teachers (n = 71, K-4 general education teachers) in L2L schools participated in professional development and consultation in two universal and two targeted interventions to reduce disruptive behaviors and promote learning. Teachers (n = 65) in SAU schools participated in professional development as usual. Multiple regression models examined teacher reports of individual-level self-efficacy, classroom-level student functioning, and school-level organizational health as predictors of stress and satisfaction. Findings revealed no significant difference between conditions on teacher work-related stress or satisfaction. Organizational health was the strongest predictor of stress and satisfaction. Training on and implementation of evidence-based classroom interventions did not appear to significantly impact teachers’ work-related stress or satisfaction. Instead, findings point to organizational climate and teacher connectedness as potential levers for change, supporting prior work on teacher stress and satisfaction in schools. The significance of targeting organizational factors may be particularly significant in urban school districts.     

Being a Body: Women’s Appearance Related Self-Views and their Dehumanization of Sexually Objectified Female Targets

When sexually objectified, women are reduced to their bodies or sexual body parts and become likely targets of dehumanization. Not only men, but also women engage in this process. In the present research, we tested the link between women’s appearance related self-views and their tendency to dehumanize sexually objectified female targets. Specifically, we test two mediational models and predict that (1) women’s motivation to look attractive to men and (2) their tendency to internalize the sociocultural beauty standards are linked with the dehumanization of sexually objectified female targets, and their level of self-objectification mediates both relations. To test these hypotheses, a sample of 55 heterosexual undergraduate female students from Northern Italy volunteered. Participants’ motivation to look attractive to men, their level of internalization of the sociocultural beauty standards, and their tendency to self-objectify was measured. Results confirmed that only sexually objectified female targets were significantly dehumanized, while their non-objectified counterparts were not. Moreover, both participants’ motivation to look attractive to men and their tendency to internalize the sociocultural beauty standards were positively linked with the dehumanization of sexually objectified female targets. As expected, these relations were mediated by participants’ level of self-objectification. These results show that higher levels of self-objectification among those women who are motivated either to look attractive to men or to internalize the sociocultural beauty standards are linked with their tendency to dehumanize sexually objectified female targets.     

Visual cues of motion that trigger animacy perception at birth: the case of self‐propulsion

Self‐propelled motion is a powerful cue that conveys information that an object is animate. In this case, animate refers to an entity's capacity to initiate motion without an applied external force. Sensitivity to this motion cue is present in infants that are a few months old, but whether this sensitivity is experience‐dependent or is already present at birth is unknown. Here, we tested newborns to examine whether predispositions to process self‐produced motion cues underlying animacy perception were present soon after birth. We systematically manipulated the onset of motion by self‐propulsion (Experiment 1) and the change in trajectory direction in the presence or absence of direct contact with an external object (Experiments 2 and 3) to investigate how these motion cues determine preference in newborns. Overall, data demonstrated that, at least at birth, the self‐propelled onset of motion is a crucial visual cue that allowed newborns to differentiate between self‐ and non‐self‐propelled objects (Experiment 1) because when this cue was removed, newborns did not manifest any visual preference (Experiment 2), even if they were able to discriminate between the stimuli (Experiment 3). To our knowledge, this is the first study aimed at identifying sensitivity in human newborns to the most basic and rudimentary motion cues that reliably trigger perceptions of animacy in adults. Our findings are compatible with the hypothesis of the existence of inborn predispositions to visual cues of motion that trigger animacy perception in adults.     

Early evidence of the Italian validation of the Trait Anxiety Scale of the State-Trait Anxiety Inventory for Children

Anxiety is one of the most widespread disorders in childhood. Researchers claim the need for a tool useful to assess the core constructs common to multiple anxiety disorders, to catch the generalized propensity to be anxious and to assess anxiety stability across the lifespan. The Trait Anxiety Scale of the State-Trait Anxiety Inventory for Children (STAIC-T) seems to fill these gaps. The present study examined STAIC-T validity in a sample of 1324 Italian children aged 8–13 years old. Scalar invariance across gender was established. Internal consistency was good. Results reported higher levels of anxiety in girls, whereas no gender differences were found. The measure demonstrated good convergent validity with the Spence Children Anxiety Scale. Findings support the validity of the STAIC-T as a brief and concise diagnostic tool to assess the anxiety proneness in Italian children.

Avoidant coping in panic disorder: a yohimbine biological challenge study

Abstract

Few studies have addressed whether the use of avoidance-oriented coping strategies is related to the development of panic in patients with panic disorder(PD). Self-report, clinician-rated, and physiological data were collected from 42 individuals who participated in a yohimbine biological challenge study, performed under double-blind, placebo-controlled conditions. Participants included 20 healthy controls and 22 currently symptomatic patients who met DSM-IV-TR diagnostic criteria for PD. Consistent with prediction, patients with PD who had higher perceived efficacy of avoidance-oriented strategies in reducing anxiety-related thoughts reported increased severity in panic symptoms during the yohimbine challenge condition as compared to the placebo. Further, patients with PD who had more fear of cognitive dyscontrol, cardiovascular symptoms, and publicly observable anxiety also reported increased severity in panic symptoms during the challenge. Healthy controls who had more fear of cardiovascular symptoms similarly reported increased severity in panic symptoms during the challenge. No effects were found for heart rate response to the challenge agent. These results provide support for the role of avoidance-oriented coping strategies and fear of anxiety-related symptoms as risk and maintenance factors in the development of panic symptoms, particularly within a biological challenge model.
