Optimism facilitates the utilisation of prior cues

It has been shown that optimists tend to rely more on their prior expectations than sensory input when making decisions of an intense nature (Geers & Lassiter, 2002). We investigated the degree to which this tendency persists over a range of discrepancies between prior cues and actual stimuli. Eighty‐seven participants were shown a subset of happy, sad and fearful pictures drawn from the Ekman facial expressions of emotion (Ekman & Oster, 1979). Each picture was preceded by a verbal cue indicating the impending emotional expression and intensity. The displayed pictures were either in agreement, slightly discrepant or very discrepant with the cue. Participants rated the extent to which they agreed/disagreed with the expectation cue. Probit signal detection models were used to produce acquiescence for each subject at each level of discrepancy. Correlation analysis was performed on acquiescence and dispositional optimism scores. There was a significant correlation between all acquiescence scores for levels of discrepancies and dispositional optimism. Optimism appears to be a trait associated with acquiescence. The apparent tendency of optimists to comply may be due to a cognitive style that relies on expectations, such that it takes them longer to recognise the extent of discrepancy between expectations and incoming information.

The magic,the life,the others: how can the imaginative dimension in reflective practice be used with student teachers? A learning experience through a self-study

In this article the author reflects upon the place imagination has in education and argues that imagination for adults is an important part of the reflective practice. The article explores the importance of going beyond the traditional way of thinking to capture the essence of understanding teaching and learning practice. The goal of this self-study is to create a way of professional development as a teacher educator which the author could utilise with teacher students. To accomplish that, the author travels to the three (imaginary) lands of reflective practice, and applies this as a way of reflective learning. The author demonstrates how reflective practices can draw together a dialogue between the embodied experience and understandings based on imaginative meanings. The author argues that reflective practice could benefit from a perspective that focuses on imaginative thoughts and more creative discussion in all aspects of education. Furthermore, to enhance students’ reflective learning one must first and foremost be able to grasp the imaginative element within oneself in order to improve students’ learning through reflective practice.     

The role of psychological defences in moderating between trauma and post‐traumatic symptoms among Palestinian men

Psychological defences are conceptualized as protective processes that help individuals to maintain their integrity in the face of threat and danger. Accordingly, their role in defending trauma victims from post‐traumatic symptoms was examined. The sample consisted of 128 Palestinian male political ex‐prisoners who had reported various degrees of torture and ill‐treatment. The first aim was to analyze the dimensionality and distribution of different defence mechanisms. The second was to examine which defences would moderate the association between the reported torture and ill‐treatment and the post‐traumatic symptoms (PTS). Third, the direct associations between reported torture and ill‐treatment and defences and between the defences and symptoms were explored. Defence mechanisms were assessed by a 40‐item version of the Defense Style Questionnaire (DSQ), and Post‐traumatic symptoms by the Harvard Trauma Questionnaire (HTQ), and experiences of torture and ill‐treatment by a scale developed for that purpose. The results show, first, that the men used predominantly mature defences such as anticipation, sublimation, suppression, and rationalization, but also relatively frequently somatization and dissociation, which are characteristic responses among trauma victims. Second, the principal component analysis revealed four defence dimensions, differentiated by the level of maturity and the approach to reality: the mature reality‐based, the consciousness‐limiting, the immature reality‐escaping, and the immature reality‐distorting defences. Third, against our hypothesis, the moderating analyses indicated that the reported torture and ill‐treatment were relatively more associated with vigilance, avoidance, and intrusion symptoms if men used consciousness‐limiting defences. Yet as expected, the mature reality‐based defences did not show a protective effect. Furthermore, a high level of reported torture and ill‐treatment was associated with a low level of the mature reality‐based defences, but not with a high level of immature defences. Last, similarly to earlier studies, the immature reality‐distorting and immature reality‐escaping defences associated directly with high, and mature reality‐based defences with low, levels of PTS‐symptoms.     

Identification with all humanity—A test of the factorial structure and measurement invariance of the scale in five countries

Identification with all humanity measured as an individual characteristic is an important factor related to social and international relations, such as concern for global issues and human rights, prosocial attitudes, intergroup forgiveness, attitudes toward immigrants, solving global problems, reactions to hate crimes and dehumanisation. We examine the factorial structure, psychometric properties and measurement invariance of the Identification with All Humanity (IWAH) scale in student samples from five countries (the United States, Poland, France, Mexico and Chile; N = 1930). Separate confirmatory factor analyses (CFAs) for each country showed a second-order model of one superordinate factor with two subfactors. The cross-country validation of the scale, based on multigroup CFA, confirmed configural and metric invariance between countries for raw scores, and full metric invariance for “pure” scores. This study showed that the IWAH scale can be successfully used for cross-country research and the results from different countries can be compared and integrated.     

Attractive memory: High destination memory for attractive faces

Research has demonstrated that destination memory (i.e., the ability to remember to whom information was previously told) can be influenced by characteristics (e.g., emotional expressions and age) of the destination. Building on this literature, we investigated whether destination memory can be influenced by the attractiveness of the destination. We invited participants to give information on attractive faces, unattractive faces, or neither‐attractive‐nor‐unattractive faces. On a recognition test, they were invited to decide to whom each piece of information had been previously told. Results demonstrated higher destination memory (1) for attractive faces than for neither‐attractive‐nor‐unattractive faces, and (2) for unattractive faces than for neither‐attractive‐nor‐unattractive faces. We attribute the higher destination memory for attractive and unattractive destinations to their distinctiveness compared with neutrally attractive destinations. We also provide some attentional explanations for the high memory for attractive and unattractive destinations.     

OBSERVATION AND COMPARISON OF MEALTIME BEHAVIORS IN A SAMPLE OF CHILDREN WITH AVOIDANT/RESTRICTIVE FOOD INTAKE DISORDERS AND A CONTROL SAMPLE OF CHILDREN WITH TYPICAL DEVELOPMENT

Despite widespread use of behavioral observations to evaluate child feeding behaviors in research and clinical practice, few studies have comprehensively characterized mealtimes or identified features that differentiate children with and without disordered feeding; these were the aims of the current study. Mealtime observations were conducted for 18 children with avoidant restrictive food intake disorder (ARFID) and 21 typically developing children. Observations were coded inductively, and associations between disorder and observed mealtime actions were examined. Most behaviors were observed across both clinical and nonclinical mealtimes, and many did not differ in frequency between children with and without ARFID. However, significant group differences were observed in the frequencies of behaviors relating to food intake, visual and physical engagement with feeding, and movement during mealtimes. The comparability of behaviors across clinical and nonclinical groups suggests that eating behaviors exist on a continuum from “normal” to “abnormal,” with group differences relating to frequency rather than type of behavior. The behavioral differences observed in this study suggest that identification of children with ARFID should focus on child engagement with food and restlessness during mealtimes. Reliance on emotional and escape‐maintained behaviors will lead to underrecognition of families in need of clinical support.     

Do we need visual subjects?

It is widely accepted within contemporary philosophy of perception that the content of visual states cannot be characterized simply as a list of represented features. This is because such characterization leads to the so-called ‘Many Properties’ problem, that is, it does not allow us to explain how the visual system is able to distinguish between scenes containing different arrangements of the same features. The usual solution to the Many Properties problem is to characterize some basic elements of content as subjects, to which features are attributed by a predication-like relation. In this paper, I reconsider this solution and claim that the Many Properties problem can be solved without postulating such subjects. What is more, I argue that an alternative approach has stronger justification given the empirical data concerning human vision.     

The first signs of prospective memory

We conducted a study to examine the impact of motivation and length of delay on performance on prospective memory (PM) tasks in 2-year of children. A total of 158 children aged exactly 24 months were asked to perform a naturalistic PM task. Length of delay (10?min; 35?min) and motivation (high; very high) were between-subjects factors. Two thirds of children had to be excluded from the analysis because of poor retrospective memory for the PM task instructions which were no longer remembered at the end of the session. For the children who did remember the instructions, both motivation and delay had significant effects on PM. Also, their PM performance was reliably above zero, even after the long delay. The findings indicate that when children as young as 24 months are able to remember the PM task instructions they can reliably succeed in PM tasks that are intrinsically motivating for them.     

Pure Modal Logic of Names and Tableau Systems

By a pure modal logic of names (PMLN) we mean a quantifier-free formulation of such a logic which includes not only traditional categorical, but also modal categorical sentences with modalities de re and which is an extension of Propositional Logic. For categorical sentences we use two interpretations: a “natural” one; and Johnson and Thomason’s interpretation, which is suitable for some reconstructions of Aristotelian modal syllogistic (Johnson in Notre Dame J Form Logic 30(2):271–284, 1989; Thomason in J Philos Logic 22(2):111–128, 1993 and J Philos Logic 26:129–141, 1997. In both cases we use Johnson-like models (1989). We also analyze different kinds of versions of PMLN, for both general and singular names. We present complete tableau systems for the different versions of PMLN. These systems enable us to present some decidability methods. It yields “strong decidability” in the following sense: for every inference starting with a finite set of premises (resp. every syllogism, every formula) we can specify a finite number of steps to check whether it is logically valid. This method gives the upper bound of the cardinality of models needed for the examination of the validity of a given inference (resp. syllogism, formula).
