The role of working memory capacity in multiple-cue probability learning

Multiple-cue probability learning (MCPL) involves learning to predict a criterion when outcome feedback is provided for multiple cues. A great deal of research suggests that working memory capacity (WMC) is involved in a wide range of tasks that draw on higher level cognitive processes. In three experiments, we examined the role of WMC in MCPL by introducing measures of working memory capacity, as well as other task manipulations. While individual differences in WMC positively predicted performance in some kinds of multiple-cue tasks, performance on other tasks was entirely unrelated to these differences. Performance on tasks that contained negative cues was correlated with working memory capacity, as well as measures of explicit knowledge obtained in the learning process. When the relevant cues predicted positively, however, WMC became irrelevant. The results are discussed in terms of controlled and automatic processes in learning and judgement.     

Interaction effects among multiple job demands: an examination of healthcare workers across different contexts

Background and Objectives: Simultaneous exposure to time, cognitive, and emotional demands is a feature of the work environment for healthcare workers, yet effects of these common stressors in combination are not well established. Design: Survey data were collected from 125 hospital employees (Sample 1, Study 1), 93 ambulance service employees (Sample 2, Study 1), and 380 aged care/disability workers (Study 2). Methods: Hierarchical multiple regressions were conducted. Results: In Sample 1, high cognitive demand exacerbated high emotional demand on psychological strain and job burnout, whereas the negative effect of high emotional demand was not present at low cognitive demand. In Sample 2, a similar pattern between emotional demand and time demand on stress-remedial intentions was observed. In Study 2, emotional demand?×?time demand and time demand?×?cognitive demand interactions again revealed that high levels of two demands were stress-exacerbating and low levels of one demand neutralized the other. A three-way interaction on job satisfaction showed the negative impact of emotional demand was exacerbated when both time and cognitive demands were high, creating a “triple disadvantage” of job demands. Conclusions: The results demonstrate that reducing some job demands helps attenuate the stressful effects of other job demands on different employee outcomes.     

Metabolic mapping of the rat cerebellum during delay and trace eyeblink conditioning

The essential neural circuitry for delay eyeblink conditioning has been largely identified, whereas much of the neural circuitry for trace conditioning has not been identified. The major difference between delay and trace conditioning is a time gap between the presentation of the conditioned stimulus (CS) and the unconditioned stimulus (US) during trace conditioning. It is this time gap or trace interval which accounts for an additional memory component in trace conditioning. Additional neural structures are also necessary for trace conditioning, including hippocampus and prefrontal cortex. This addition of forebrain structures necessary for trace but not delay conditioning suggests other brain areas become involved when a memory gap is added to the conditioning parameters. A metabolic marker of energy use, radioactively labeled glucose analog, was used to compare differences in glucose analog uptake between delay, trace, and unpaired experimental groups in order to identify new areas of involvement within the cerebellum. Known structures such as the interpositus nucleus and lobule HVI showed increased activation for both delay and trace conditioning compared to unpaired conditioning. However, there was a differential amount of activation between anterior and posterior portions of the interpositus nucleus between delay and trace, respectively. Cerebellar cortical areas including lobules IV and V of anterior lobe, Crus I, Crus II, and paramedian lobule also showed increases in activity for delay conditioning but not for trace conditioning. Delay and trace eyeblink conditioning both resulted in increased metabolic activity within the cerebellum but delay conditioning resulted in more widespread cerebellar cortical activation.     

Gender-related Needs, Challenges, and Dangers in the Immigration Experience in Israel of Emerging Adults from the Former Soviet Union

In-depth interviews were conducted to examine gender-related patterns of adaptation and maladaptation, and the relationship between adaptation and relationships (parents, friends, and romantic partners) for 34 emerging adult immigrants from the Former Soviet Union in Israel. Qualitative analysis highlighted gender-related needs, difficulties, and challenges following the immigration experience. Women’s adaptation was connected to mutually supportive and empathic relationships with parents, friends, and romantic partners. Maladaption for women was connected to overly close, nonmutual, and enmeshed relationships with parents, which led to feelings of guilt or to distant relationships that lacked support and intimacy. Adaptation for men was connected to inner strengths that enabled achievement and success in acculturative tasks, which led to feelings of mastery, competence, and self-definition combined with respect and valuing the relationship they have with their family. In contrast, maladaption among men was not connected to relationships but to a lack of inner strengths needed to succeed in developmental and immigration-related tasks. Despite the gender-related distinction found among less adaptive individuals, adaptive young immigrants, women and men alike, were more characterized by an ability to balance between needs of self and needs of others in their family relationships. As such, narratives of adaptive emerging adult immigrants emphasized gender similarities, whereas those of less adaptive immigrants emphasized gender differences.     

Learning from explaining: does it matter if mom is listening?

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat the solutions. Generating explanations (to selves or moms) improved problem-solving accuracy at posttest, and explaining to mom led to the greatest problem-solving transfer. The study indicates that explanation prompts can facilitate transfer in children as young as 5 years and reveals that it matters if mom is listening.     

The Moral Virtues and Theological Ethics (second edition). By Romanus Cessario

The call of the Second Vatican Council for the renewal of moral theology has received very divergent responses. This article identifies and compares three such proposals. The underlying presupposition for this analysis is that each proposal begins with a divergent understanding of where the tradition went awry. Hence, the proposed cures ended up irreconcilable. This article seeks to describe ‘as precisely as possible the nature of the confusion and its sources, showing where attention must be directed if a solution is to be discovered.’ ¹ 1 The anonymous referee of the Heythrop Journal.
     

Modal Mereology and Modal Supervenience

David Lewis insists that restrictivist composition must be motivated by and occur due to some intuitive desiderata for a relation R among parts that compose wholes, and insists that a restrictivist??s relation R must be vague. Peter van Inwagen agrees. In this paper, I argue that restrictivists need not use such examples of relation R as a criterion for composition, and any restrictivist should reject a number of related mereological theses. This paper critiques Lewis and van Inwagen (and others) on their respective mereological metaphysics, and offers a Golden Mean between their two opposite extremes. I argue for a novel account of mereology I call Modal Mereology that is an alternative to Classical Mereology. A modal mereologist can be a universalist about the possible composition of wholes from parts and a restrictivist about the actual composition of wholes from parts. I argue that puzzles facing Modal Mereology (e.g., puzzles concerning Cambridge changes and the Problem of the Many, and how to demarcate the actual from the possible) are also faced in similar forms by classical universalists. On my account, restricted composition is rather motivated by and occurs due to a possible whole??s instantiating an actual type. Universalists commonly believe in such types and defend their existence from objections and puzzles. The Modal Mereological restrictivist can similarly defend the existence of such types (adding that such types are the only wholes) from similar objections and puzzles.     

Maternal illusory control predicts socialization strategies and toddler compliance

This study examined the relation between mothers' perception of their capacity for controlling infant crying and a later measure of parent-toddler social interaction-compliance with parental requests. Fifty-seven mothers participated in (a) a laboratory task when their children were 5 months old to assess mothers' perception of control and (b) a toy-cleanup task when their children were 24 months old to assess toddler compliance. Perception-of-control scores on the laboratory task reflected accuracy of perception and ranged from accurate to greatly overestimating control, with an overestimation referred to as an illusion of control. Mothers were categorized into three illusion-of-control groups: low, moderate, and high. Toddlers of mothers in the low and high illusion-of-control groups were more likely to be categorized as highly defiant than were toddlers of mothers in the moderate-illusion group. Mothers with high illusory control were most likely to use a high power-assertion strategy (negative control), and when negotiating, their toddlers' expression of autonomy was most likely to escalate into defiance.     

Assessing African American adolescents' risk for suicide attempts: attachment theory

The threat of separation from a parent theoretically increases the risk of adolescent suicide attempts. The present study evaluated this and other hypothesized risk factors in a sample of adolescent suicide attempters and nonsuicidal controls, using the Psychiatric Consultation Checklist (Lyon, 1987). Stepwise logistic regression was used to predict group membership. It was found that threat of separation from a parental figure, insomnia, neglect, substance abuse, suicidal ideation, and failing grades were the strongest predictors of suicide attempt. Ten predictor variables correctly identified 97% of suicide attempters and 86% of nonattempters. Unexpected findings included high levels of truancy, threatening others, and separation from a parent before the age of 12 among nonattempters.
