Meta-Analysis of the Effects of Computerized Cognitive Training on Executive Functions: a Cross-Disciplinary Taxonomy for Classifying Outcome Cognitive Factors

The growing prevalence of neurodegenerative disorders associated with aging and cognitive decline has generated increasing cross-disciplinary interest in non-pharmacological interventions, such as computerized cognitive training (CCT), which may prevent or slow cognitive decline. However, inconsistent findings across meta-analytic reviews in the field suggest a lack of cross-disciplinary consensus and on-going debate regarding the benefits of CCT. We posit that a contributing factor is the lack of a theoretically-based taxonomy of constructs and representative tasks typically used. An integration of the Cattell-Horn-Carroll (CHC) taxonomy of broad and narrow cognitive factors and the Miyake unity-diversity theory of executive functions (EF) is proposed (CHC-M) as an attempt to clarify this issue through representing and integrating the disciplines contributing to CCT research. The present study assessed the utility of this taxonomy by reanalyzing the Lampit et al. (2014) meta-analysis of CCT in healthy older adults using the CHC-M framework. Results suggest that: 1) substantively different statistical effects are observed when CHC-M is applied to the Lampit et al. meta-analytic review, leading to importantly different interpretations of the data; 2) typically-used classification practices conflate Executive Function (EF) tasks with fluid reasoning (Gf) and retrieval fluency (Gr), and Attention with sensory perception; and 3) there is theoretical and practical advantage in differentiating attention and working-memory tasks into the narrow shifting, inhibition, and updating EF domains. Implications for clinical practice, particularly for our understanding of EF are discussed.     

Incremental validity of mindfulness-based attention in relation to the concurrent prediction of anxiety and depressive symptomatology and perceptions of health

This investigation evaluated the role of mindfulness-based attention in concurrently predicting anxiety and depressive symptomatology and perceived health functioning in a community sample of 170 young adults (95 females; mean age (Mage) = 22.2 years, SD = 7.6). Partially consistent with prediction, results indicated that, relative to negative and positive affectivity and emotional expression and processing associated with approach-oriented coping, mindfulness-based attention incrementally predicted anhedonic depressive, but not anxious arousal, symptoms. Additionally, consistent with prediction, mindfulness-based attention demonstrated incremental validity in relation to perceived health, and the degree of impairment of health in terms of physical and mental functioning. Results are discussed in relation to the construct development of mindfulness-based attention, and specifically, the role(s) of this factor in emotional and physical health processes.     

Validation of Self-Report Measures of Emotional and Physical Distress Tolerance

The Distress Tolerance Scale (DTS) and Discomfort Intolerance Scale (DIS) are self-report measures developed for the assessment of emotional and physical distress tolerance, respectively. However, little evidence exists for their construct and specifically criterion-related validity. The current study examined the associations of these self-report measures with lab-based assessments of perceived emotional tolerance and physical discomfort tolerance. Undergraduate participants (N?=?166) were administered four film clips intended to induce sadness, disgust, fear, and anger, and a handgrip persistence task intended to elicit physical discomfort. The DTS, but not the DIS, was significantly associated with self-reported emotional tolerance and perceived threat associated with each film after controlling for emotional intensity. Among DTS subscales, the absorption subscale was the only subscale incrementally predictive of negative perceptions of the sad film, the appraisal subscale was incrementally predictive of negative perceptions of the other three films, and little support for the incremental validity of the tolerance and regulation subscales was found. The DTS also incrementally predicted tolerance and perceived threat of film-elicited emotions across films after controlling for anxiety sensitivity. The DIS was only marginally predictive of handgrip task persistence and was unrelated to emotional film perceptions. Overall, these findings uniquely add to the empirical literature on the construct and criterion-related validity of the DTS and DIS.     

Social-Psychological Interventions for Intergroup Reconciliation: An Emotion Regulation Perspective

Intergroup reconciliation is a requirement for lasting peace in the context of intergroup conflicts. In this article, we offer an emotion regulation perspective on social-psychological interventions aimed at facilitating intergroup reconciliation. In the first section of the article, we conceptualize intergroup reconciliation as an emotion-regulation process involving positive affective change and offer a framework that integrates the emotion regulation and intergroup reconciliation literatures. In the sections that follow, we review social-psychological interventions that involve changes in beliefs and identity and assess their effects on specific intergroup emotions pertinent for intergroup reconciliation. More specifically, we focus our discussion on specific reconciliation-oriented intervention strategies and their relation to emotions pertinent for facilitating reconciliation, including intergroup hatred, anger, guilt, hope, and empathy. In the final section, we consider key implications and growth points for the field of intergroup reconciliation.     

Transitivity,Space, and Hand: The Spatial Grounding of Syntax

Previous research has linked the concept of number and other ordinal series to space via a spatially oriented mental number line. In addition, it has been shown that in visual scene recognition and production, speakers of a language with a left‐to‐right orthography respond faster to and tend to draw images in which the agent of an action is located to the left of the patient. In this study, we aim to bridge these two lines of research by employing a novel method that measures the spatial bias produced by transitive sentences that use a wide variety of abstract and concrete verbs. Across four experiments, participants read sentences and then responded to probe words appearing on either the left or right sides of the screen. Probe words consisted of agents, patients, other words in the sentence, or newly encountered words. We found consistent lateral biases to responding to agents and patients, which appears to be independent of order of mention in the sentence but which does reflect a correspondence between position in the sentence and role in the causal sequence of the action. Our results also show that this spatial bias is driven by the use of the hands in two different ways: The left hand shows a greater sensitivity to the spatial effect than the right hand, and vocal responses produce no spatial effect.     

Paying a price: culture, trust, and negotiation consequences

Three studies contrasting Indian and American negotiators tested hypotheses derived from theory proposing why there are cultural differences in trust and how cultural differences in trust influence negotiation strategy. Study 1 (a survey) documented that Indian negotiators trust their counterparts less than American negotiators. Study 2 (a negotiation simulation) linked American and Indian negotiators' self-reported trust and strategy to their insight and joint gains. Study 3 replicated and extended Study 2 using independently coded negotiation strategy data, allowing for stronger causal inference. Overall, the strategy associated with Indian negotiators' reluctance to extend interpersonal (as opposed to institutional) trust produced relatively poor outcomes. Our data support an expanded theoretical model of negotiation, linking culture to trust, strategies, and outcomes.     

The role of higher order image statistics in masking scene gist recognition

In the present article, we investigated whether higher order image statistics, which are known to be carried by the Fourier phase spectrum, are sufficient to affect scene gist recognition. In Experiment 1, we compared the scene gist masking strength of four masking image types that varied in their degrees of second- and higher order relationships: normal scene images, scene textures, phase-randomized scene images, and white noise. Masking effects were the largest for masking images that possessed significant higher order image statistics (scene images and scene textures) as compared with masking images that did not (phase-randomized scenes and white noise), with scene image masks yielding the largest masking effects. In a control study, we eliminated all differences in the second-order statistics of the masks, while maintaining differences in their higher order statistics by comparing masking by scene textures rather than by their phase-randomized versions, and showed that the former produced significantly stronger gist masking. Experiments 2 and 3 were designed to test whether conceptual masking could account for the differences in the strength of the scene texture and phase-randomized masks used in Experiment 1, and revealed that the recognizability of scene texture masks explained just 1% of their masking variance. Together, the results suggest that (1) masks containing the higher order statistical structure of scenes are more effective at masking scene gist processing than are masks lacking such structure, and (2) much of the disruption of scene gist recognition that one might be tempted to attribute to conceptual masking is due to spatial masking.     

Why does language interfere with vision-based tasks?

Conversation with a remote person can interfere with performing vision-based tasks. Two experiments tested the role of general executive resources and spatial attentional resources in this interference. Both experiments assessed performance in vision-based tasks as participants engaged in a language task involving a virtual remote speaker. In both experiments, the language task interfered with the vision task more when participants were speaking or planning what to say next than when they were listening. In Experiment 1, speaking or planning what to say next were also associated with higher interference from a visual distractor than listening, indicating that preparing to speak and speaking pose higher executive requirements than listening. In both experiments, localizing the voice of the remote speaker to the front of participants slightly reduced interference in comparison to other directions. This suggests that remote conversation requires spatial attention resources for representing the position of the remote person.     

Anxiety Sensitivity Moderates Relations Among Tobacco Smoking,Panic Attack Symptoms,and Bodily Complaints in Adolescents

The present study evaluated associations among smoking and anxiety sensitivity (fear of anxiety and anxiety related sensations) in predicting panic attack symptomatology, somatic complaints, and depressive symptomatology in a community sample of adolescents (ages 12 to 17 years; N=206). As predicted, the combination of high levels of anxiety sensitivity and being a current smoker predicted panic symptomatology and somatic complaints, but not depressive symptomatology. These findings suggest anxiety sensitivity may moderate the relation between smoking and prototypical panic psychopathology variables (panic attacks and somatic complaints) even after controlling for gender and negative affectivity, and that these associations are specific to panic-relevant processes. The primary implication of the study findings is that there may be segments of the adolescent population who are at relatively greater risk for panic-related problems by virtue of individual differences in AS and smoking status.
