Conceptualising and testing the Narnian Character Virtue Scales: a study among 12- to 13-year-old students

ABSTRACT

This paper sets out to examine and to operationalise 12 key character virtues identified within C. S. Lewis’ Narnian texts: courage, curiosity, forgiveness, fortitude, gratitude, hard work, humility, integrity, justice, love, self-control, and wisdom. A pilot study among 56 year eight students (12–13 years of age) generated nine five-item instruments displaying adequate internal consistency reliability, and suggested ways in which the other three measures (curiosity, integrity, and love) could be enhanced in future work. Construct validity was explored by examining the correlations between these 12 character virtues and sex, self-concept, and empathy, and by locating these 12 character virtues within the three-dimensional psychological space proposed by Eysenck’s model of personality.

Infant Developmental Outcomes: A Family Systems Perspective

The aim of the current study was to examine whether parental mental health, parent–infant relationship, infant characteristics and couple's relationship factors were associated with the infant's development. Forty‐two families took part at three time points. The first, at 3 months postpartum, involved a video recorded observation (CARE‐index) of parent–infant interactions. At 5 months postpartum, in‐depth clinical interviews (the Birmingham Interview of Maternal Mental Health) assessed parental mental health and parental perceptions of their relationship with their infant, their partner and their infant's characteristics. Finally, the Bayley Scales III was carried out 17 months postpartum to assess the infants' cognitive, language and motor development. A higher mother–infant relationship quality was significantly associated with more optimal language development, whilst a higher father–infant relationship quality was associated with more advanced motor development. Additionally, maternal postnatal post‐traumatic stress disorder had a negative impact on the infant's cognitive development, whilst maternal prenatal depression was associated with a less optimal infant's language development. The largest prediction was afforded by parental perceptions of their infant's characteristics. The findings indicate that such perceptions may be crucial for the infant's development and imply that negative internal parental perceptions should be considered when assessing risk factors or designing interventions to prevent negative child outcomes.

Using robots to understand animal cognition

In recent years, robotic animals and humans have been used to answer a variety of questions related to behavior. In the case of animal behavior, these efforts have largely been in the field of behavioral ecology. They have proved to be a useful tool for this enterprise as they allow the presentation of naturalistic social stimuli whilst providing the experimenter with full control of the stimulus. In interactive experiments, the behavior of robots can be controlled in a manner that is impossible with real animals, making them ideal instruments for the study of social stimuli in animals. This paper provides an overview of the current state of the field and considers the impact that the use of robots could have on fundamental questions related to comparative psychology: namely, perception, spatial cognition, social cognition, and early cognitive development. We make the case that the use of robots to investigate these key areas could have an important impact on the field of animal cognition.     

Not all ambiguous words are created equal: An EEG investigation of homonymy and polysemy

Event-related potentials (ERPs) were used to investigate the time-course of meaning activation of different types of ambiguous words. Unbalanced homonymous ("pen"), balanced homonymous ("panel"), metaphorically polysemous ("lip"), and metonymically polysemous words ("rabbit") were used in a visual single-word priming delayed lexical decision task. The theoretical distinction between homonymy and polysemy was reflected in the N400 component. Homonymous words (balanced and unbalanced) showed effects of dominance/frequency with reduced N400 effects predominantly observed for dominant meanings. Polysemous words (metaphors and metonymies) showed effects of core meaning representation with both dominant and subordinate meanings showing reduced N400 effects. Furthermore, the division within polysemy, into metaphor and metonymy, was supported. Differences emerged in meaning activation patterns with the subordinate meanings of metaphor inducing differentially reduced N400 effects moving from left hemisphere electrode sites to right hemisphere electrode sites, potentially suggesting increased involvement of the right hemisphere in the processing of figurative meaning.     

Knowledge and use of memory strategies in amnestic mild cognitive impairment

Despite the inclusion of memory strategy training in many interventions for amnestic mild cognitive impairment (aMCI), little research has directly examined knowledge and use of memory strategies in aMCI and their relationship to memory performance in order to guide the development of targeted interventions. The present study aimed to compare strategy knowledge and use between an aMCI and a healthy older adult (HOA) sample, and to determine the contribution of strategy knowledge and use to memory performance in each of these groups. The sample comprised 37 aMCI and 52 HOA participants aged over 60 years. All participants completed questionnaires to assess strategy knowledge and self-reported use of internal and external strategies in everyday life. In addition, strategy use was observed on the measures of retrospective and prospective memory performance (the CVLT-II and the CAMPROMPT). The aMCI group demonstrated decreased strategy knowledge and observed use of internal strategies, although equivalent observed use of external strategies compared with the HOA group. Furthermore, they reported equivalent use of both internal and external strategies. Observed use of strategies was significantly associated with retrospective memory performance for both groups and prospective memory performance for the aMCI group, supporting the inclusion of strategy training in interventions.
