Individual working memory capacity is uniquely correlated with feature-based attention when combined with spatial attention

A growing literature suggests that working memory and attention are closely related constructs. Both involve the selection of task-relevant information, and both are characterized by capacity limits. Furthermore, studies using a variety of methodological approaches have demonstrated convergent working memory and attention-related processing at the individual, neural and behavioral level. Given the varieties of both constructs, the specific kinds of attention and WM must be considered. We find that individuals' working memory capacity (WMC) uniquely interacts with feature-based attention when combined with spatial attention in a cuing paradigm (Posner, 1980). Our findings suggest a positive correlation between WM and feature-based attention only within the spotlight of spatial attention. This finding lends support to the controlled attention view of working memory by demonstrating that integrated feature-based expectancies are uniquely correlated with individual performance on a working memory task.     

Speaking rate from proximal and distal contexts is used during word segmentation

A series of eye-tracking and categorization experiments investigated the use of speaking-rate information in the segmentation of Dutch ambiguous-word sequences. Juncture phonemes with ambiguous durations (e.g., [s] in 'eens (s)peer,' "once (s)pear," [t] in 'nooit (t)rap,' "never staircase/quick") were perceived as longer and hence more often as word-initial when following a fast than a slow context sentence. Listeners used speaking-rate information as soon as it became available. Rate information from a context proximal to the juncture phoneme and from a more distal context was used during on-line word recognition, as reflected in listeners' eye movements. Stronger effects of distal context, however, were observed in the categorization task, which measures the off-line results of the word-recognition process. In categorization, the amount of rate context had the greatest influence on the use of rate information, but in eye tracking, the rate information's proximal location was the most important. These findings constrain accounts of how speaking rate modulates the interpretation of durational cues during word recognition by suggesting that rate estimates are used to evaluate upcoming phonetic information continuously during prelexical speech processing.     

Initial relationship goal and couple therapy outcomes at post and six-month follow-up

The purpose of this study was to investigate the relationship between client initial goal for couple therapy (i.e., improve the relationship or clarify the viability of the relationship) and the outcomes (including their relationship status, i.e., separated or together) at posttreatment as well as at 6-month follow-up. Two hundred forty-nine couples (N = 498 individuals) seeking treatment for relationship distress in a naturalistic setting were treated by 20 therapists. Client initial relationship goal was attained by intake paperwork protocol, which included client initial goal for couple therapy and client perception of partner goal. Clients who reported that their goal was to improve the relationship reported better outcomes at post. Couples who reported their goal was to improve the relationship were less likely to break up at a 6-month follow-up. Of the 115 couples stating they wanted to improve the relationship, only nine (7.8%) couples were separated at 6 months. In contrast, of the 16 couples in which both partners wanted to clarify the relationship prior to therapy, nine (56%) were separated at follow-up. Therapist awareness of each individual's relationship goal prior to couple therapy could enhance outcomes, and treatment tailored according to initial goals could set the stage for positive outcomes however defined.     

Fast thought speed induces risk taking

In two experiments, we tested for a causal link between thought speed and risk taking. In Experiment 1, we manipulated thought speed by presenting neutral-content text at either a fast or a slow pace and having participants read the text aloud. In Experiment 2, we manipulated thought speed by presenting fast-, medium-, or slow-paced movie clips that contained similar content. Participants who were induced to think more quickly took more risks with actual money in Experiment 1 and reported greater intentions to engage in real-world risky behaviors, such as unprotected sex and illegal drug use, in Experiment 2. These experiments provide evidence that faster thinking induces greater risk taking.     

What Makes a Quality Therapy? A Consideration of Parsimony,Ease, and Efficiency

Evaluations of psychotherapy have traditionally focused on symptom reduction as the primary standard by which their value is determined. This has contributed to the appearance of equivalence between many therapies that may differ considerably in complexity, feasibility, amount of homework and therapist contact required, expected cost, speed of symptom decline, and transdiagnostic utility. In the current paper, I make the case that these are fundamental features related to quality that should be considered in psychotherapy development, randomized controlled trials, and dissemination efforts. Empirically supported treatments for different disorders are evaluated based on these criteria, and special consideration is given to cognitive-behavioral treatments for anxiety disorders. Specific recommendations for a quality-oriented clinical research agenda are also provided.     

The Necessities of Perfect Freedom

This article is a reflection on Augustine's suggestion that Christians have significant theological reasons to accept that freedom need not be correlated with having choices. Following his lead, I explore questions about freedom and agency raised by the perfect freedom of the saints in heaven, Jesus' sinless earthly life and the freedom with which the triune God is eternally blessed. My thesis is that those who worship the triune God and praise the sinless perfection of Christ and the heavenly saints have reason to accept a ‘normative’ conception of freedom, according to which certain kinds of necessity are not merely compatible with perfect freedom but intrinsic to it.     

Slope estimation and viewing distance of the observer

The overestimation of geographical slant is one of the most sizable visual illusions. However, in some cases estimates of close-by slopes within the range of the observer’s personal space have been found to be rather accurate. We propose that the seemingly diverse findings can be reconciled when taking the viewing distance of the observer into account. The latter involves the distance of the observer from the slope (personal space, action space, and vista space) and also the eye-point relative to the slope. We separated these factors and compared outdoor judgments to those collected with a three-dimensional (3D) model of natural terrain, which was within arm’s reach of the observer. Slope was overestimated in the outdoors at viewing distances between 2 m and 138 m. The 3D model reproduced the errors in monocular viewing; however, performance was accurate with stereoscopic viewing. We conclude that accurate slant perception breaks down as soon as the situation exits personal space, be it physically or be it by closing one eye.     

Revisiting the factor structure of the 12-item Disgust Propensity and Sensitivity Scale – Revised: Evidence for a third component

The 12-item Disgust Propensity and Sensitivity Scale – Revised (DPSS-12) is widely used to assess the tendency for an individual to respond with disgust (i.e., disgust propensity) and how bothered an individual is by the experience of disgust (i.e., disgust sensitivity). However, heterogeneous items included in the DPSS-12 call into question the adequacy of its two-factor structure. The current study examined the factor structure of the DPSS-12 using two large, nonclinical student samples. Exploratory factor analyses revealed three lower order factors: (1) disgust propensity, (2) disgust sensitivity, and (3) self-focused/ruminative disgust. Confirmatory factor analyses supported the three-factor solution and demonstrated that the model fit better than a unidimensional or two-factor model. Further, a modified two-factor model that excluded the third factor provided a better fit than the original two-factor model. Additionally, the third domain explained a significant portion of the total variance, and evidenced a distinctive pattern of association with relevant constructs including obsessional symptoms. These data suggest the need to refine our knowledge about the latent structure of disgust reflected by this measure.     

Lost in the crowd: Entitative group membership reduces mind attribution

This research examined how and why group membership diminishes the attribution of mind to individuals. We found that mind attribution was inversely related to the size of the group to which an individual belonged (Experiment 1). Mind attribution was affected by group membership rather than the total number of entities perceived at once (Experiment 2). Moreover, mind attribution to an individual varied with the perception that the individual was a group member. Participants attributed more mind to an individual that appeared distinct or distant from other group members than to an individual that was perceived to be similar or proximal to a cohesive group (Experiments 3 and 4). This effect occurred for both human and nonhuman targets, and was driven by the perception of the target as an entitative group member rather than by the knowledge that the target was an entitative group member (Experiment 5).
