Belief in a just world and subjective well-being: mothers of normal and Down syndrome children

A cross-sectional study examined the relationship between three dimensions of the belief in a just world and the subjective well-being of Pakistani mothers of normal and Down syndrome children (n = 100 each). Personal belief in a just world and two dimensions of general belief in a just world-beliefs in immanent and ultimate justice-were assessed along with four dimensions of subjective well-being: life satisfaction, mood, state anxiety, and depression. It was hypothesized that personal belief in a just world and belief in ultimate justice would be positively associated with subjective well-being for both groups of mothers. Results were obtained through moderated regression analyses. In line with our hypothesis, personal belief in a just world positively predicted life satisfaction and mood level and negatively predicted state anxiety and depression in both groups of mothers. In contrast, beliefs in immanent and ultimate justice were not consistently adaptive. In particular, the more the mothers of a Down syndrome child believed in immanent justice, the more anxiety they experienced the previous week. In addition, the more the mothers of normal children believed in ultimate justice, the more they experienced anxiety. The pattern of results persisted when controlled for mothers' education, the total number of their children and marital status. Overall, the results support the role of personal belief in a just world as a personal resource in adverse as well as normal life circumstances.     

Pacifiers Disrupt Adults’ Responses to Infants’ Emotions

Research shows that pacifiers disrupt infants' mimicry of facial expressions. This experiment examines whether pacifiers interfere with caretakers' ability to mimic infants' emotions. Adults saw photographs of infants with or without a pacifier. When infants had pacifiers, perceivers showed reduced EMG activity to infants' smiles. Smiles of infants using a pacifier were also rated as less happy than smiles depicted without a pacifier. The same pattern was observed for expressions of distress: adults rated infants presented with pacifiers as less sad than infants without pacifiers. We discuss deleterious effects of pacifier use for the perceiver's resonance with a child's emotions.     

Suicide ideation and depression in university students in Botswana

The study aimed at exploring suicide ideation and its relationship to depression in university students in Botswana. Data were collected from 122 undergraduate students (68.9% females, 31.1% males) with a mean age of 20.02 years. Depressive symptoms were measured with an adapted version of Beck's Depression Inventory-II. In total, 47.5% of the respondents reported suicide ideation, 28.7% reported previous suicide attempts, and the mean depression score was 19.14. Suicide ideation correlated strongly with total depression scores. The level of depression severity was linearly related to suicide ideation but 14.3% of respondents who scored at the level of minimal depression and 53.8% of those who scored at the level of mild depression had also contemplated suicide. The level of education of respondents’ mothers had an inverse relationship with suicide ideation and with depression in that those whose mothers had a tertiary level education were less likely to engage in suicide ideation and had significantly lower depression scores. The results are discussed from within the specific social ecological context of Botswana.     

Measuring the combined risk to young children's cognitive development: An alternative to cumulative indices

In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development measured at 36 and 58 months of age along with 10 potential risks during this period of development. Comparing a cumulative index of these risks against the previously undocumented alternative of confirmatory factor analysis using formative measurement, this study found differences favouring the factor analysis. The factor analysis procedure demonstrated greater predictive power of children's cognitive development while it systematically tested two of the assumptions implicit in cumulative risk indices.     

Inference in the Wild: A Framework for Human Situation Assessment and a Case Study of Air Combat

Situation awareness is a key construct in human factors and arises from a process of situation assessment (SA). SA comprises the perception of information, its integration with existing knowledge, the search for new information, and the prediction of the future state of the world, including the consequences of planned actions. Causal models implemented as Bayesian networks (BNs) are attractive for modeling all of these processes within a single, unified framework. We elicited declarative knowledge from two Royal Australian Air Force (RAAF) fighter pilots about the information sources used in the identification (ID) of airborne entities and the causal relationships between these sources. This knowledge was represented in a BN (the declarative model) that was evaluated against the performance of 19 RAAF fighter pilots in a low‐fidelity simulation. Pilot behavior was well predicted by a simple associative model (the behavioral model) with only three attributes of ID. Search for information by pilots was largely compensatory and was near‐optimal with respect to the behavioral model. The average revision of beliefs in response to evidence was close to Bayesian, but there was substantial variability. Together, these results demonstrate the value of BNs for modeling human SA.     

The Metaphysics of Causal Models

This paper presents an attempt to integrate theories of causal processes—of the kind developed by Wesley Salmon and Phil Dowe—into a theory of causal models using Bayesian networks. We suggest that arcs in causal models must correspond to possible causal processes. Moreover, we suggest that when processes are rendered physically impossible by what occurs on distinct paths, the original model must be restricted by removing the relevant arc. These two techniques suffice to explain cases of late pre?mption and other cases that have proved problematic for causal models.

Manipulating cues in involuntary autobiographical memory: Verbal cues are more effective than pictorial cues

In two experiments, pictorial cues were compared with their verbal labels to assess their effectiveness in eliciting involuntary autobiographical memories. Cues were relatively complex in Experiment 1 (e.g., relaxing on a beach) and simple objects in Experiment 2 (e.g., a ball). In both experiments, participants went through a vigilance task in which they were presented with frequent nontarget and rare target visual stimuli. Pictures or their corresponding verbal labels were also displayed on both target and nontarget stimuli, but participants were told that these were irrelevant to the task. They were asked to interrupt the vigilance task whenever they became aware of task-unrelated mental contents and to report them. In both experiments, more involuntary memories were elicited in the verbal cue condition, rather than in the pictorial cue condition. This result is discussed in relation to previous work that highlighted the greater effectiveness of verbal cues in memory tasks.     

A multi-factorial framework for understanding reckless driving—appraisal indicators and perceived environmental determinants

The current study adopted an approach, in which reckless driving is perceived as related to both personal and environmental factors. Young drivers (N = 295) reported on reckless driving related threat and challenge appraisals, their perceived control over reckless driving, their disregard for negative consequences of this specific behavior, positive feedback received on their driving, environmental driving-climate and negative driving modeling. The dependent measure was self-reported frequency of reckless driving. Findings indicated that challenge and self-efficacy appraisals, along with negative environmental influences were related to higher frequency of risky driving, whereas threat appraisals, as well as positive feedback, were related to a lower frequency of reckless driving. In addition, whereas for men, self-efficacy in driving strongly predicted reckless driving, disregard for negative consequences was an important predictor for women. The results are discussed in view of an evaluating process of personal cognitive-emotional resources and environmental support proposed by Lazarus. Recommendations are made regarding the potential effectiveness of using positive appeals in prevention interventions.
