Color Selectivity of the Spatial Congruency Effect: Evidence from the Focused Attention Paradigm

The multisensory response enhancement (MRE), occurring when the response to a visual target integrated with a spatially congruent sound is stronger than the response to the visual target alone, is believed to be mediated by the superior colliculus (SC) (Stein & Meredith, 1993). Here, we used a focused attention paradigm to show that the spatial congruency effect occurs with red (SC-effective) but not blue (SC-ineffective) visual stimuli, when presented with spatially congruent sounds. To isolate the chromatic component of SC-ineffective targets and to demonstrate the selectivity of the spatial congruency effect we used the random luminance modulation technique (Experiment 1) and the tritanopic technique (Experiment 2). Our results indicate that the spatial congruency effect does not require the distribution of attention over different sensory modalities and provide correlational evidence that the SC mediates the effect.     

Heterogeneity of treatment changes after psychodynamic therapy within a one year follow‐up: A replication study

Naturalistic psychotherapy effect studies commonly report effect sizes for the total sample. However, a previous study of SCL‐90 Global Severity Index (GSI) improvement in a large outpatient sample used a cluster analytic strategy and reported clinical relevant outcome trajectories that could be grouped into early within‐treatment improvement, late improvement in the follow‐up period, and deteriorating patients with slight improvement that was lost at follow‐up. We explore GSI outcome trajectories and clinical significant change in a sample of 320 patients at a public psychiatric outpatient psychodynamic group therapy unit, the majority with anxiety, personality, and mood disorders. The study revealed large discharge and follow‐up effect sizes but more than one third of the patients were without measurable improvement. The major clusters described above were confirmed, and revealed unique clinical and socio‐demographic characteristics. Late improvers, as compared with early improvers, were characterized by anxiety symptoms and lack of network support after controlling for GSI at admission. Similarly, deteriorating patients had longer duration of illness and less favourable social characteristics compared with the other two groups. Early improving patients were less likely to have participated in short‐term groups, and only one third participated in additional treatment compared with more than 69% of the other patients. Severe and socially affected psychiatric patients, and patients with anxiety and agoraphobic symptoms may be less optimally treated in short‐term time limited psychodynamic groups. There is an obvious need for diversity of treatment offers, better integration of psycho‐social treatment components, and long‐term open ended treatment.     

Causal conditional reasoning and semantic memory retrieval: a test of the semantic memory framework

This study tested and refined a framework that proposes a mechanism for retrieving alternative causes and disabling conditions (Cummins, 1995) during reasoning. Experiment 1 examined the relation between different factors affecting retrieval. The test revealed high correlations between the number of possible alternative causes or disabling conditions and their strength of association and plausibility. Experiment 2 explored the hypothesis that due to a more extended search process, conditional inferences would last longer when many alternative causes or disabling conditions were available. Affirmation of the consequent (AC) and modus ponens (MP) latencies showed the hypothesized pattern. Denial of the antecedent (DA) and modus tollens (MT) inferences did not show latency effects. The experiment also identified an effect of the number of disabling conditions on AC and DA acceptance. Experiment 3 measured efficiency of disabler retrieval by a limited time, disabler generation task. As predicted, better disabler retrieval was related to lower acceptance of the MP and MT inferences.     

Characterizing belief bias in syllogistic reasoning: A hierarchical Bayesian meta-analysis of ROC data

The belief-bias effect is one of the most-studied biases in reasoning. A recent study of the phenomenon using the signal detection theory (SDT) model called into question all theoretical accounts of belief bias by demonstrating that belief-based differences in the ability to discriminate between valid and invalid syllogisms may be an artifact stemming from the use of inappropriate linear measurement models such as analysis of variance (Dube et al., Psychological Review, 117(3), 831–863, 2010). The discrepancy between Dube et al.’s, Psychological Review, 117(3), 831–863 (2010) results and the previous three decades of work, together with former’s methodological criticisms suggests the need to revisit earlier results, this time collecting confidence-rating responses. Using a hierarchical Bayesian meta-analysis, we reanalyzed a corpus of 22 confidence-rating studies (N =?993). The results indicated that extensive replications using confidence-rating data are unnecessary as the observed receiver operating characteristic functions are not systematically asymmetric. These results were subsequently corroborated by a novel experimental design based on SDT’s generalized area theorem. Although the meta-analysis confirms that believability does not influence discriminability unconditionally, it also confirmed previous results that factors such as individual differences mediate the effect. The main point is that data from previous and future studies can be safely analyzed using appropriate hierarchical methods that do not require confidence ratings. More generally, our results set a new standard for analyzing data and evaluating theories in reasoning. Important methodological and theoretical considerations for future work on belief bias and related domains are discussed.     

Perspective taking and theory of mind in hide and seek

Does theory of mind play a significant role in where people choose to hide an item or where they search for an item that has been hidden? Adapting Anderson’s "Hide-Find Paradigm" Anderson et al. (Action, Perception and Performance, 76, 907–913, 2014) participants viewed homogenous or popout visual arrays on a touchscreen table. Their task was to indicate where in the array they would hide an item, or to search for an item that had been hidden, by either a friend or a foe. Critically, participants believed that their sitting location at the touchtable was the same as—or opposite to—their partner's location. Replicating Anderson et al., participants tended to (1) select items nearer to themselves on homogenous displays, and this bias was stronger for a friend than foe; and (2) select popout items, and again, more for a friend than foe. These biases were observed only when participants believed that they shared the same physical perspective as their partner. Collectively, the data indicate that theory of mind plays a significant role in hiding and finding, and demonstrate that the hide-find paradigm is a powerful tool for investigating theory of mind in adults.     

Paulo Freire and Philosophy for Children: A Critical Dialogue

This paper is an attempt to connect the Brazilian Paulo Freire’s well known educational thinking with the “philosophy for children” movement. It considers the relationship between the creator of philosophy for children (P4C), Matthew Lipman and Freire through different attempts to establish a relationship between these two educators. The paper shows that the relationship between them is not as close as many supporters of P4C have claimed, especially in Latin America. It also considers the context of Educational Policies in our time and why Freire’s understanding of the politics of education makes it impossible to be Freirean and at the same time be neutral or favorable to the actual status quo. Finally, after presenting Lipman’s understanding of the relationship between philosophy, education and democracy and their connection to capitalism, it proposes ways to begin the political path of philosophizing with children inspired by Paulo Freire’s educational thinking. As a result, a more politically committed path to doing philosophy with children is offered.     

A force of change: Chris Peterson and the US Army’s Global Assessment Tool

The US Army launched the Global Assessment Tool (GAT) – a 105-item psychometric instrument taken by approximately one million soldiers annually – in October, 2009 in support of a population-wide resilience development initiative known as the Comprehensive Soldier and Family Fitness (CSF2) program. The lead developer of the GAT was Chris Peterson, and his work on this project – along with that of Nansook Park and Colonel Carl Castro – will likely leave an important and indelible mark on not only the Army, but also the field of military psychology. In this paper, we provide more detail on the history and components of the GAT. In addition, we demonstrate the practical utility of the GAT by showing that high-performing soldiers (soldiers who attained Ranger status) have relatively high GAT scores, and that soldiers with behavioral problems generally evidence low GAT scores. We conclude by discussing future directions of GAT methodology and usage in support of research.     

Deeds that Help and Words that Hurt: Helping and Gossip as Moderators of the Relationship Between Leader–Member Exchange and Advice Network Centrality

We examine the relationship between leader–member exchange (LMX) quality and advice network centrality using multisource data from a sample of 250 retail employees and their respective managers in Turkey to test our hypothesized model of value and costs of being sought out for advice. Drawing upon the tenets of network generation theory (Nebus, 2006 ), we predict that the tendency of focal actors to help others and their own tendency to gossip would be behavioral moderators of the relationship between LMX quality and their advice network centrality. Consistent with network generation theory, our results reveal that LMX quality is positively related to centrality only for those actors with a high tendency to help coworkers and a low tendency to gossip about coworkers, suggesting that behaviors indicating helpfulness and discretion are necessary for high LMX members to maintain a central position in their work group's advice network. Implications and future research directions are discussed.
