Reality monitoring in anosognosia for hemiplegia

Anosognosia for hemiplegia (AHP) is a lack of awareness about paralysis following stroke. Recent explanations use a ‘forward model’ of movement to suggest that AHP patients fail to register discrepancies between internally- and externally-generated sensory information. We predicted that this failure would impair the ability to recall from memory whether information is internally- or externally-generated (i.e., reality monitor). Two experiments examined this prediction. Experiment 1 demonstrated that AHP patients exhibit a reality monitoring deficit for non-motor information (i.e., perceived vs. imagined drawings), whilst hemiplegic controls without anosognosia (nonAHP) perform like age-matched healthy volunteers (HVs). Experiment 2 explored if this deficit occurs when AHP patients discriminate performed, imagined, or observed movement. Results showed impaired reality monitoring for movements in AHP and nonAHP patients relative to HVs. Findings suggest that reality monitoring processes not directly related to movement, together with a failure to reality monitor movements, contribute to the pathogenesis of AHP.     

The effectiveness of feedback in multiple-cue probability learning

How effective are different types of feedback in helping us to learn multiple contingencies? This article attempts to resolve a paradox whereby, in comparison to simple outcome feedback, additional feedback either fails to enhance or is actually detrimental to performance in nonmetric multiple-cue probability learning (MCPL), while in contrast the majority of studies of metric MCPL reveal improvements at least with some forms of feedback. In three experiments we demonstrate that if feedback assists participants to infer cue polarity then it can in fact be effective in nonmetric MCPL. Participants appeared to use cue polarity information to adopt a linear judgement strategy, even though the environment was nonlinear. The results reconcile the paradoxical contrast between metric and nonmetric MCPL and support previous findings of people's tendency to assume linearity and additivity in probabilistic cue learning.     

Effects of Maternal Depression Symptoms and Alcohol Use Problems on Child Internalizing and Externalizing Behavior Problems

Empirical evidence suggests maternal behavioral health problems are significant predictors of child behavioral health difficulties, but it is unclear of the specific relation of maternal alcohol use problems and depression symptoms with child internalizing and externalizing behavior problems. The purpose of the study is to examine the impact of maternal depression symptoms and alcohol use problems on children’s internalizing and externalizing behavior problems over a period of 5 years. Implications for intervention may differ depending on which type of maternal behavioral health concerns predicts which child behavior problem. A total of 1874 families eligible for Early Head Start participated. Maternal depression symptoms and alcohol use problems were assessed when children were in preschool, and internalizing and externalizing behavior problems were assessed when children were in fifth grade. Clinical internalizing behavior problems was best predicted by maternal depression symptoms, whereas clinical externalizing behavior problems was best predicted by maternal alcohol use problems. Children were almost twice as likely to have clinical internalizing behavior problems when mothers exhibited very elevated depression symptoms compared to when mothers displayed minimal symptoms. A similar relation was found with maternal alcohol use problems and clinical externalizing behavior problems. Our findings highlight the importance of understanding and treating various kinds of behavioral health concerns in mothers of young children.     

Can psychological interventions increase optimism? A meta-analysis

Greater optimism is related to better mental and physical health. A number of studies have investigated interventions intended to increase optimism. The aim of this meta-analysis was to consolidate effect sizes found in randomized controlled intervention studies of optimism training and to identify factors that may influence the effect of interventions. Twenty-nine studies, with a total of 3319 participants, met criteria for inclusion in the analysis. A significant meta-analytic effect size, g = .41, indicated that, across studies, interventions increased optimism. Moderator analyses showed that studies had significantly higher effect sizes if they used the Best Possible Self intervention, provided the intervention in person, used an active control, used separate positive and negative expectancy measures rather than a version of the LOT-R, had a final assessment within one day of the end of the intervention, and used completer analyses rather than intention-to-treat analyses. The results indicate that psychological interventions can increase optimism and that various factors may influence effect size.     

Compassion at the mirror: Exposure to a mirror increases the efficacy of a self-compassion manipulation in enhancing soothing positive affect and heart rate variability

We tested whether a mirror could enhance the efficacy of a self-compassion manipulation in increasing soothing positive affect and heart rate variability (HRV). Eighty-six participants generated four phrases they would use to soothe and encourage their best friend. Second, they described an episode where they criticized themselves and were assigned to one of three conditions: (a) repeat the four phrases to themselves while looking at the mirror; (b) repeat the four phrases to themselves without the mirror; (c) look at themselves in the mirror without repeating the phrases. Participants in condition (a) reported higher levels of ‘soothing’ positive affect and HRV compared to participants in conditions (b) and (c). The effect of the ‘phrases at the mirror’ manipulation on soothing affect was mediated by increased common humanity. The mirror enhances the efficacy of this self-compassion manipulation in activating the soothing affect system connected with parasympathetic nervous system activity.     

Same-sex parent families in Italy: Validation of the Coparenting Scale-Revised for lesbian mothers and gay fathers

Even though Italy is still struggling to establish equal rights and access to assisted reproduction techniques for sexual minorities, an increasing number of lesbian women and gay men are now becoming parents. There are only a few studies that have evaluated coparenting in same-sex couples. However, these addressed adoptive couples and not the lesbian and gay parent families through donor insemination or surrogacy, respectively. This study examined the psychometric properties of the Coparenting Scale-Revised and its relationship with dyadic adjustment, discipline management, and internalized sexual stigma in Italian same-sex-planned families. The factor structure showed a satisfactory internal consistency and criterion validity with correlates of coparenting behaviours. While Family Integrity factor was confirmed, Disparagement and Reprimand dimensions collapsed into Conflict factor. Non-genetic parents showed lower levels of conflict than genetic parents. Most importantly, coparenting emerged as a significant function not shaped by gender, but influenced by parental status and internalized sexual stigma.     

Imitation of causally opaque versus causally transparent tool use by 3- and 5-year-old children

We investigated whether the tendency to imitate or emulate is influenced by the availability of causal information, and the amount of information available in a display. Three and 5-year-old children were shown by either a live or video model how to obtain a reward from either a clear or an opaque puzzle box. Some of the actions in the sequence were causally relevant to retrieving the reward, whereas others were irrelevant. The clear box made the causally irrelevant actions visible, whereas the opaque box prevented them from being seen. Results indicated that both 3- and 5-year-old children imitated the irrelevant actions regardless of the availability of causal information following a live demonstration. In contrast, the 3-year-olds employed an emulative approach, omitting irrelevant actions, when the information available was degraded in a video demonstration. However, the 5-year-olds were unaffected by the degraded information and employed an imitative approach. We suggest that imitation develops to be such an adaptive human strategy that it may often be employed at the expense of task efficiency.
