The Varieties of Forgiveness Experience: Working toward a Comprehensive Definition of Forgiveness

The definition of forgiveness was explored in a group of 270 young adults, and the underlying dimensions of their definitions compared with those of philosophers, theologians and psychological researchers. Three dimensions were identified: orientation (self, other), direction (passive letting go of negative experiences, active enhancement of positive experiences) and form (emotion, cognition and behavior). Definitions employing a passive letting go of negative experiences were associated with more state forgiveness. Gender differences were found in state forgiveness and in the employment of passive vs. active dimensions of forgiveness. Dr. Kathleen A. Lawler-Row is Professor of Psychology at East Carolina University. Her work focuses on the physiological and health correlates of forgiveness. Correspondence to Dr. K. A.

Aging holocaust survivors' well-being and adjustment: associations with ambivalence over emotional expression

A sample of 90 older respondents (age range: 78-83 years) composed of 2 Holocaust groups (camp inmates and other survivors) and a comparison group completed questionnaires measuring ambivalence over emotional expression, positive and negative affect, and psychosocial adjustment. The Holocaust groups rated higher than the comparison group on negative affect and ambivalence over emotional expression and lower on psychosocial adjustment. Ambivalence over emotional expression mediated the effects of the Holocaust on negative affect. These data suggest that the effects of the Holocaust are evident 60 years later, highlighting the role of ambivalence over emotional expression in the well-being of Holocaust survivors.     

Delay-dependent working memory impairment in young-adult and aged 5-HT1BKO mice as assessed in a radial-arm water maze

Serotonin (5-HT) plays a modulatory role in mnemonic functions, especially by interacting with the cholinergic system. The 5-HT1B receptor is a key target of this interaction. The 5-HT1B receptor knockout mice were found previously to exhibit a facilitation in hippocampal-dependent spatial reference memory learning. In the present study, we submitted mice to a delayed spatial working memory task, allowing the introduction of various delays between an exposure trial and a test trial. The 5-HT1BKO and wild-type mice learned the task in a radial-arm water maze (returning to the most recent presented arm containing the escape platform), and exhibited a high level of performance at delays of 0 and 5 min. However, at the delay of 60 min, only 5-HT1BKO mice exhibited an impairment. At a delay of 90 min, all mice were impaired. Treatment by scopolamine (0.8 mg/kg) induced the same pattern of performance in wild type as did the mutation for short (5 min, no impairment) and long (60 min, impairment) delays. The 22-month-old wild-type and knockout mice exhibited an impairment at short delays (5 and 15 min). The effect of the mutation affected both young-adult and aged mice at delays of 15, 30, and 60 min. Neurobiological data show that stimulation of the 5-HT1B receptor inhibits the release of acetylcholine in the hippocampus, but stimulates this in the frontal cortex. This dual function might, at least in part, explain the opposite effect of the mutation on reference memory (facilitation) and delay-dependent working memory (impairment). These results support the idea that cholinergic-serotonergic interactions play an important role in memory processes.     

Measurement of Ability in Adaptive Learning and Assessment Systems when Learners Use On-Demand Hints

Adaptive learning and assessment systems support learners in acquiring knowledge and skills in a particular domain. The learners’ progress is monitored through them solving items matching their level and aiming at specific learning goals. Scaffolding and providing learners with hints are powerful tools in helping the learning process. One way of introducing hints is to make hint use the choice of the student. When the learner is certain of their response, they answer without hints, but if the learner is not certain or does not know how to approach the item they can request a hint. We develop measurement models for applications where such on-demand hints are available. Such models take into account that hint use may be informative of ability, but at the same time may be influenced by other individual characteristics. Two modeling strategies are considered: (1) The measurement model is based on a scoring rule for ability which includes both response accuracy and hint use. (2) The choice to use hints and response accuracy conditional on this choice are modeled jointly using Item Response Tree models. The properties of different models and their implications are discussed. An application to data from Duolingo, an adaptive language learning system, is presented. Here, the best model is the scoring-rule-based model with full credit for correct responses without hints, partial credit for correct responses with hints, and no credit for all incorrect responses. The second dimension in the model accounts for the individual differences in the tendency to use hints.     

Relationship Quality among Chronically Ill Children and their Parents

The present study examined the quality of parent–child relationships as reported by 383 parents of chronically ill children. The medical condition category, child’s mobility, education type and childcare assistance were examined. Parents answered the Parent–Child Relationship Inventory (PCRI). In addition, 45 parents of chronically ill children were interviewed. The results indicated a significant difference in most aspects of the PCRI (limit setting, promotion of autonomy, communication, satisfaction and involvement) across medical condition categories. Further child variables (mobility, assistance and education type) had an effect on the PCRI subscales as well. Interview analysis revealed a difference in the reported quality of parent–child relationships between medical conditions categories. Parents of mentally ill children primarily felt anger and guilt in their relationship with their ill children, whereas parents of children with cancer and autoimmune disease primarily felt depressed. Our results suggest the need for further study of parent–child relationships in and between different chronic childhood medical conditions in an attempt to address parents’ and children’s needs in an optimal way.     

The Principle of Summation

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.
