Linking metaphor comprehension with analogical reasoning: Evidence from typical development and autism spectrum disorder

We examined the relationship between metaphor comprehension and verbal analogical reasoning in young adults who were either typically developing (TD) or diagnosed with Autism Spectrum Disorder (ASD). The ASD sample was highly educated and high in verbal ability, and closely matched to a subset of TD participants on age, gender, educational background, and verbal ability. Additional TD participants with a broader range of abilities were also tested. Each participant solved sets of verbal analogies and metaphors in verification formats, allowing measurement of both accuracy and reaction times. Measures of individual differences in vocabulary, verbal working memory, and autistic traits were also obtained. Accuracy for both the verbal analogy and the metaphor task was very similar across the ASD and matched TD groups. However, reaction times on both tasks were longer for the ASD group. Additionally, stronger correlations between verbal analogical reasoning and working memory capacity in the ASD group indicated that processing verbal analogies was more effortful for them. In the case of both groups, accuracy on the metaphor and analogy tasks was correlated. A mediation analysis revealed that after controlling for working memory capacity, the inter-task correlation could be accounted for by the mediating variable of vocabulary knowledge, suggesting that the primary common mechanisms linking the two tasks involve language skills.     

Predicting others' actions via grasp and gaze: evidence for distinct brain networks

During social interactions, how do we predict what other people are going to do next? One view is that we use our own motor experience to simulate and predict other people's actions. For example, when we see Sally look at a coffee cup or grasp a hammer, our own motor system provides a signal that anticipates her next action. Previous research has typically examined such gaze and grasp-based simulation processes separately, and it is not known whether similar cognitive and brain systems underpin the perception of object-directed gaze and grasp. Here we use functional magnetic resonance imaging to examine to what extent gaze- and grasp-perception rely on common or distinct brain networks. Using a 'peeping window' protocol, we controlled what an observed actor could see and grasp. The actor could peep through one window to see if an object was present and reach through a different window to grasp the object. However, the actor could not peep and grasp at the same time. We compared gaze and grasp conditions where an object was present with matched conditions where the object was absent. When participants observed another person gaze at an object, left anterior inferior parietal lobule (aIPL) and parietal operculum showed a greater response than when the object was absent. In contrast, when participants observed the actor grasp an object, premotor, posterior parietal, fusiform and middle occipital brain regions showed a greater response than when the object was absent. These results point towards a division in the neural substrates for different types of motor simulation. We suggest that left aIPL and parietal operculum are involved in a predictive process that signals a future hand interaction with an object based on another person's eye gaze, whereas a broader set of brain areas, including parts of the action observation network, are engaged during observation of an ongoing object-directed hand action.     

Exploring the Effectiveness of a Mixed-Diagnosis Group Cognitive Behavioral Therapy Intervention Across Diverse Populations

Depression and anxiety are the most common mental health disorders seen in clinical practice and they are highly comorbid. Cognitive behavioral therapy (CBT) has been demonstrated as an effective treatment for both depression and anxiety but is often not available to all individuals who could benefit from it. This paper investigates the effectiveness of a mixed-diagnosis group CBT intervention that incorporates mindfulness meditation for individuals presenting with depression and/or anxiety: CBT Basics II. This intervention was evaluated across two distinct mental health programs to determine both if it can demonstrate positive results and if it is feasible to implement in these types of programs. Sample 1 (n = 42 completers) consisted of higher-functioning individuals in a general mental health program. Sample 2 (n = 53 completers) consisted of individuals with more chronic and severe mental health diagnoses. Overall, intent-to-treat analyses revealed improvements in psychiatric symptoms, and increases in CBT knowledge and mindfulness skill across both programs. This indicates that CBT Basics II is effective across diverse mental health populations and shows promise for improving access to CBT.     

Pyrrhonism in the Political Philosophy of Thomas Hobbes

The importance of Pyrrhonism to Hobbes's political philosophy is much greater than has been recognized. He seems to have used Pyrrhonist arguments to support a doctrine of moral relativity, but he was not a sceptic in the Pyrrhonist sense. These arguments helped him to develop his teaching that there is no absolute good or evil; to minimise the purchase of natural law in the state of nature and its restrictions on the right of nature; virtually to collapse natural law into civil law; and to make the sovereign the political, moral and theological epicenter of his political system.     

Approaching Homelessness: An Integral Re-Frame

This article explores a metaview of the many faces of homelessness. It analyzes an evolutionary meaning of home and suggests that ever-complexifying life conditions influence how societies enforce conformity to the status quo of homefulness. It goes on to describe how homelessness might be reframed as a complex adaptive form of survival for diversity generators who cannot or will not conform to the status quo. The article proposes an integral framework on which intervention strategies could be structured to provide evolutionary, appropriate, and flexible approaches to homelessness.

Abstract

The aim of this paper is to identify what I take to be the main conceptual problem in Lewis’ semantics for counterfactuals when the Limit Assumption (LA) is not satisfied, what I call the Discrimination Problem (DP), and to present and discuss a modification of Lewis’ semantics that aims at solving DP. First, I outline Lewis’ semantics, highlighting the aspects that will be relevant for our discussion. Second, I present DP and discuss it with a heuristic example. Third, I present the new proposal and comment some formal consequences and the objections they give rise to. Fourth, I present an allegedly equivalent version of the proposal and discuss the difference between counterfactuals and strict conditionals. Finally, I defend that the two proposals are different and argue for the first one as the best way of capturing two intuitions that seem in conflict when the LA is not satisfied. I conclude with a dilemma: either the proposal here defended works or LA is inescapable. Thus, if the proposal doesn’t work, the paper must then be considered as an indirect defense of the Limit Assumption.     

Therapeutic Assessment With Children: A Pilot Study of Treatment Acceptability and Outcome

Therapeutic Assessment (TA) with children is a hybrid of psychological assessment and short-term intervention. It uses the ongoing process and results of psychological assessment to enhance parents' understanding of their child and to facilitate change. Clinical reports and single case studies suggest that TA with children is an acceptable and effective brief intervention. However, no aggregate data have been published to support this claim. This pilot study investigated the acceptability and preoutcome–postoutcome of TA with 14 clinically referred children with emotional and behavior problems and their parents. Results indicated high treatment acceptability as well as significantly decreased child symptomatology and enhanced family functioning as reported by children and mothers. In addition, mothers demonstrated a significant increase in positive emotion and a significant decrease in negative emotion pertaining to their children's challenges and future. The findings, although limited due to the design and small sample size, support assertions from published single case studies that TA is possibly an efficacious child and family intervention for children with emotional and behavioral problems and should be studied in a larger, comparison design.     

Predicting Psychologists' Intentions to Integrate Complementary and Alternative Therapies Into Their Practice

Drawing on an extended Theory of Planned Behaviour (TPB) framework, we employed a cross‐sectional design study to investigate psychologists' intentions to integrate complementary and alternative therapies (CAT) into their practice via recommending CAT to clients or referring clients to CAT practitioners. Participants were registered practicing psychologists from a range of therapeutic orientations (e.g., narrative, cognitive behavioural, psychodynamic). The psychologists were either recruited by phone, following a search of the Internet, or were contacted through their place of employment (hospitals, university counselling service). Those who agreed to participate (N = 122; n = 88 females, n = 34 males) completed a questionnaire that included standard TPB items of attitude, subjective norm, and perceived behavioural control, along with items measuring perceived risk, past behaviour, CAT knowledge, and gender. The outcome variables of interest were (a) intention to recommend CAT to clients and (b) intention to refer clients to CAT practitioners. Structural equation modelling revealed that the extended model was a good fit, explaining 69% (recommending CAT) and 51% (referring to CAT practitioners) of the variance in intentions. For both behaviours, direct paths from attitude and subjective norm to intentions were observed, with perceived risk and past behaviour influencing the TPB predictors of attitudes, subjective norm, and perceived behavioural control. The findings illustrate the role that cognitive and risk factors have on psychologists' decisions to integrate CAT into their practice. Understanding psychologists' cognitions and decisions about CAT integration forms an important basis on which to consider future changes in policy or practice.
