The effects of assessment type on verbal ratings of conditional stimulus valence and contingency judgments: implications for the extinction of evaluative learning

Recent research on causal learning found (a) that causal judgments reflect either the current predictive value of a conditional stimulus (CS) or an integration across the experimental contingencies used in the entire experiment and (b) that postexperimental judgments, rather than the CS's current predictive value, are likely to reflect this integration. In the current study, the authors examined whether verbal valence ratings were subject to similar integration. Assessments of stimulus valence and contingencies responded similarly to variations of reporting requirements, contingency reversal, and extinction, reflecting either current or integrated values. However, affective learning required more trials to reflect a contingency change than did contingency judgments. The integration of valence assessments across training and the fact that affective learning is slow to reflect contingency changes can provide an alternative interpretation for researchers' previous failures to find an effect of extinction training on verbal reports of CS valence.     

Predictions and causal estimations are not supported by the same associative structure

Studies performed by different researchers have shown that judgements about cue-outcome relationships are systematically influenced by the type of question used to request those judgements. It is now recognized that judgements about the strength of the causal link between a cue and an outcome are mostly determined by the cue-outcome contingency, whereas predictions of the outcome are more influenced by the probability of the outcome given the cue. Although these results make clear that those different types of judgement are mediated by some knowledge of the normative differences between causal estimations and outcome predictions, they do not speak to the underlying processes of these effects. The experiment presented here reveals an interaction between the type of question and the order of trials that challenges standard models of causal and predictive learning that are framed exclusively in associative terms or exclusively in higher order reasoning terms. However, this evidence could be easily explained by assuming the combined intervention of both types of process.     

Marxism and Science Studies: A Sweep through the Decades

This article outlines the distinctive contribution of Marxism to science studies. It traces the trajectory of Marxist ideas through the decades from the origins of Marxism to the present conjuncture. It looks at certain key episodes, such as the arrival of a Soviet delegation at the International History of Science Congress in London in 1931, as well as subsequent interactions between Marxists and exponents of other positions at later international congresses. It focuses on the impact of several generations of Marxists who have engaged with science in diverse ways. It examines the influence of Marxism on contemporary trends in science studies. It concludes that Marxism survives in circuitous and complex ways. It argues not only for a positive interpretation of its contribution in the past but for its explanatory and ethical power in the present and future.     

“Flash” dance: How speed modulates perceived duration in dancers and non-dancers

Speed has been proposed as a modulating factor on duration estimation. However, the different measurement methodologies and experimental designs used have led to inconsistent results across studies, and, thus, the issue of how speed modulates time estimation remains unresolved. Additionally, no studies have looked into the role of expertise on spatiotemporal tasks (tasks requiring high temporal and spatial acuity; e.g., dancing) and susceptibility to modulations of speed in timing judgments. In the present study, therefore, using naturalistic, dynamic dance stimuli, we aimed at defining the role of speed and the interaction of speed and experience on time estimation. We presented videos of a dancer performing identical ballet steps in fast and slow versions, while controlling for the number of changes present. Professional dancers and non-dancers performed duration judgments through a production and a reproduction task. Analysis revealed a significantly larger underestimation of fast videos as compared to slow ones during reproduction. The exact opposite result was true for the production task. Dancers were significantly less variable in their time estimations as compared to non-dancers. Speed and experience, therefore, affect the participants' estimates of time. Results are discussed in association to the theoretical framework of current models by focusing on the role of attention.     

Family Cohesion and Health-Related Quality of Life of Children with Type 1 Diabetes: The Mediating Role of Parental Adjustment

Despite the increasing number of studies on the health-related quality of life (HRQOL) of children with type 1 diabetes (T1D), little is known about the influence of family and parental factors on this outcome. This study aimed to explore whether family cohesion and children’s HRQOL were connected through three indicators of parental psychological adjustment (parenting stress, depressive symptoms, and anxious symptoms) as well as whether these links varied according to the child’s age. Levels of family cohesion, parenting stress, and depression/anxiety symptoms of parents of children with T1D and parents of healthy children were compared. The sample included 88 child–parent dyads composed of children/adolescents (8–18 years old) with T1D and one of their parents and 121 dyads composed of healthy children/adolescents and one of their parents. The parents completed self-report measures of family cohesion, parenting stress, and emotional adjustment, and the children completed measures of HRQOL. Testing of the hypothesized moderated mediational model showed that higher HRQOL ratings in children were associated with higher levels of cohesion through lower levels of parental stress, regardless of the child’s age. Parents of children with T1D perceived less cohesion and felt more anxiety and stress about parenting tasks compared to parents of healthy children. Our findings suggest that parents of children with T1D are at an increased risk of psychological maladjustment. Moreover, this study highlights the interrelation between family/parental functioning and child adjustment and makes an innovative contribution by identifying a mechanism that may account for the link between family and child variables.     

Associations between attachment‐related symptoms and later psychological problems among international adoptees: Results from the FinAdo study

We examined the associations between attachment‐related symptoms (symptoms of reactive attachment disorder (RAD), symptoms of disinhibited social engagement disorder (DSED), and clinging) and later psychological problems among international adoptees. The study population comprised internationally adopted children (591 boys and 768 girls, 6–15 years) from the ongoing Finnish Adoption (FinAdo) study. Data were gathered with self‐administered questionnaires both from adoptive parents and from adoptees aged over 9 years. Attachment‐related symptoms were measured using of a short (8‐item) questionnaire and later behavioral/emotional problems were assessed using the Child Behavior Checklist (CBCL) and the Five to Fifteen (FTF) scale for attention‐deficit/hyperactivity disorder (ADHD) symptoms. RAD and DSED symptom subscales were associated with an increased risk of emotional and behavioral problems and ADHD. Especially the mixed type of attachment‐related symptoms was strongly associated with later emotional and behavioral problems.     

Costs and Benefits of Newcomer Adjustment Tactics

Research on information seeking, feedback seeking, and newcomer proactive behavior reveals that employees use various criteria in deciding how to act. This article investigates an integrative framework for such criteria proposed by Cooper‐Thomas and Wilson, comprising three domains (performance, ego, social) and two factors (cost, benefit). Three independent scenario‐based studies were used to test their model. The results supported some propositions of the model, such as the primacy of performance concerns, yet failed to support other propositions, with benefits consistently predominating over costs. Factors that might underlie the contradictory results were systematically controlled for, namely the sample, hypothetical scenario, and initial asset position. Theoretical and practical implications are discussed.     

Narrative Practices and Positive Aging: A Reflection about Life Celebration in a Group of Old Women

The main objective of this article is to address the impact of narrative practices in life celebration after the age of 80 and in the co-construction of a community-positive future. We share here an exploratory reflection about the narratives of a group of older women integrated in a community project. The Wednesday Tea Project (Chá das Quartas) has been ongoing for 4 years, and involves a group of old women experiencing high levels of loneliness and isolation in their small village in Portugal. The Wednesday Tea Project is based on positive psychology methodologies and consists of ritualized sessions that encourage participatory group dynamics. To describe how this project has highlighted the benefits of narrative practices, we utilized a series of scaffolding questions. Some of the most relevant outcomes of this project are: (a) the deconstruction of the dominant social discourse; (b) the publication of a book; (c) the reduction of loneliness feelings by re-membering significant figures; and (d) new levels of action both to women and the community as a consequence of a re-authoring process. Narrative practices seem to have contributed to the consolidation of all time dimensions, giving these women the opportunity to celebrate life after the age of 80, while also allowing the community to be part of and to benefit from the process. A reflection about the contributions of this article to a paradigm change toward positive aging is presented.     

‘Infinity Means it Goes on Forever’: Siblings' Informal Teaching of Mathematics

Sibling‐directed teaching of mathematical topics during naturalistic home interactions was investigated in 39 middle‐class sibling dyads at two time points. At time 1 (T1), siblings were 2 and 4 years of age, and at time 2 (T2), siblings were 4 and 6 years of age. Intentional sequences of sibling‐directed mathematical teaching were coded for (i) topics (e.g., number), (ii) contexts (e.g., play with materials/toys), and (iii) type of knowledge (conceptual and procedural). Siblings engaged in teaching number, geometry, and measurement at T1 and demonstrated preliminary evidence of teaching of grouping, relations, and operations at T2. Regarding context, at T1, mathematical teaching occurred most frequently during play with materials/toys, while at T2, games with rules were prominent. Teaching of conceptual or procedural knowledge varied over time and by topic and context. Findings are discussed in light of recent work on understanding children's mathematical knowledge as it develops in the informal family context. Copyright © 2015 John Wiley & Sons, Ltd.
