Explaining efficient search for conjunctions of motion and form: Evidence from negative color effects

Dent, Humphreys, and Braithwaite (2011) showed substantial costs to search when a moving target shared its color with a group of ignored static distractors. The present study further explored the conditions under which such costs to performance occur. Experiment 1 tested whether the negative color-sharing effect was specific to cases in which search showed a highly serial pattern. The results showed that the negative color-sharing effect persisted in the case of a target defined as a conjunction of movement and form, even when search was highly efficient. In Experiment 2, the ease with which participants could find an odd-colored target amongst a moving group was examined. Participants searched for a moving target amongst moving and stationary distractors. In Experiment 2A, participants performed a highly serial search through a group of similarly shaped moving letters. Performance was much slower when the target shared its color with a set of ignored static distractors. The exact same displays were used in Experiment 2B; however, participants now responded “present” for targets that shared the color of the static distractors. The same targets that had previously been difficult to find were now found efficiently. The results are interpreted in a flexible framework for attentional control. Targets that are linked with irrelevant distractors by color tend to be ignored. However, this cost can be overridden by top-down control settings.     

Health Related Quality of Life and Social Support in Pediatric Patients with Pacemakers

Prior research evaluating health-related quality of life (HRQOL) among pediatric patients with internal cardiac devices has primarily focused on children with cardiac defibrillators, with scant attention devoted to pacemaker recipients. Social support has been conceptualized as a protective factor that partially accounts for differences in HRQOL. This study compares the HRQOL of children with pacemakers with that of healthy children, and examines associations between HRQOL and social support. Twenty-seven pediatric pacemaker recipients completed measures of HRQOL and social support. Their parents also completed measures of child HRQOL. High concordance was found for child and parent-proxy reports of child HRQOL. Children with pacemakers and their parents both reported relatively low child HRQOL when compared to published normative data for healthy children and parents of healthy children. Family and friends emerged as the sources of support positively associated with the greatest number of HRQOL domains. In conclusion, these findings suggest that pediatric pacemaker recipients experience lower levels of HRQOL compared to healthy peers, and that social support from those closest to the child is associated with their perceived HRQOL.     

Revealing human inductive biases for category learning by simulating cultural transmission

We explored people’s inductive biases in category learning—that is, the factors that make learning category structures easy or hard—using iterated learning. This method uses the responses of one participant to train the next, simulating cultural transmission and converging on category structures that people find easy to learn. We applied this method to four different stimulus sets, varying in the identifiability of their underlying dimensions. The results of iterated learning provide an unusually clear picture of people’s inductive biases. The category structures that emerge often correspond to a linear boundary on a single dimension, when such a dimension can be identified. However, other kinds of category structures also appear, depending on the nature of the stimuli. The results from this single experiment are consistent with previous empirical findings that were gleaned from decades of research into human category learning.     

Restorative effects of virtual nature settings

Previous research regarding the potential benefits of exposing individuals to surrogate nature (photographs and videos) has found that such immersion results in restorative effects such as increased positive affect, decreased negative affect, and decreased stress. In the current experiment, we examined whether immersion in a virtual computer-generated nature setting could produce restorative effects. Twenty-two participants were equally divided between two conditions, while controlling for gender. In each condition, participants performed a stress-induction task, and were then immersed in virtual reality (VR) for 10 minutes. The control condition featured a slide show in VR, and the nature experimental condition featured an active exploration of a virtual forest. Participants in the nature condition were found to exhibit increased positive affect and decreased stress after immersion in VR when compared to those in the control condition. The results suggest that immersion in virtual nature settings has similar beneficial effects as exposure to surrogate nature. These results also suggest that VR can be used as a tool to study and understand restorative effects.     

British-English norms and naming times for a set of 539 pictures: The role of age of acquisition

In the present study, we presented picture-naming latencies along with ratings for a set of important characteristics of pictures and picture names: age of acquisition, frequency, picture-name agreement, name agreement, visual complexity, familiarity, and word length. The validity of these data was established by calculating correlations with previous studies. Regression analyses show that our ratings account for a larger amount of variance in RTs than do previous data. RTs were predicted by all variables except complexity and length. A complete database presenting details about all of these variables is available in the supplemental materials, downloadable from http://brm.psychonomic-journals.org/content/supplemental.     

Weight ratings of others: The effects of multiple target and rater features

The present study investigated factors that affect the subjective analysis of the weight of other individuals. Three hundred and thirty-three participants viewed figures varying in muscularity, adiposity, gender, and race. For each of the eighteen figures (targets), a 2 (rater gender: male, female) × 3 (rater race/ethnicity: Caucasian, African American, Hispanic) × 3 (target race/ethnicity: Caucasian, African American, Hispanic) repeated measures ANCOVA was conducted (BMI was covaried). Overall, there were few significant effects, however, for some of the figural stimuli, African American raters assigned lower weight ratings than did Caucasian and Hispanic raters. The findings offer support for further investigation of ethnic differences in weight ratings as a potential factor that might inform ethnic differences in overweight and obesity prevalence.     

Referrals to chaplains: The role of religion and spirituality in healthcare settings

Given the increasing importance of understanding how healthcare workers interact with the principal person designated to meet patients’ spiritual needs— the chaplain— the current study provides an inter-disciplinary perspective of the role of chaplains (and spirituality) in patients’ emotional, physical, and spiritual health. The study surveyed a randomly selected national sample of hospital directors in four disciplines: medicine (n?=?278), nursing (n?=?230), social services (n?=?229), and pastoral care (n?=?470). Participants rated the importance of referring patients to chaplains for four different areas: pain/depression, anxiety/anger, treatment issues, and loss/death/meaning. Results revealed significant differences in referral patterns for type of hospital, professional discipline, the hospital's religious affiliation, and self-reported spirituality. Results are discussed in relation to historical views of spirituality and religion within the different disciplines.     

Self-Efficacy for Affect Regulation as a Predictor of Future Life Satisfaction and Moderator of the Negative Affect—Life Satisfaction Relationship

Life satisfaction is an important index of mental health and also predicts other important outcomes such as longevity and decreased mortality. Negative affect has a unique inverse relationship with life satisfaction across the life span. Therefore, determining psychological factors that uniquely predict future life satisfaction and that reduce the trait negative affect—life satisfaction relationship is theoretically and clinically important. In light of recent evidence from long-term longitudinal studies that self-efficacy for regulation of negative emotions (SERN) predicts higher future life satisfaction, as well as evidence from a cross-sectional study that a subtype of SERN—self-efficacy for regulating anger—buffers the relationship between trait negative affect and life satisfaction, we tested whether SERN and subtypes of SERN predicted higher life satisfaction and buffered the negative affect—life satisfaction relationship longitudinally over short time periods. After controlling for time 1 life satisfaction, higher time 1 self-efficacy for regulating despondency and distress (SEDes) predicted higher future life satisfaction over average time periods of 17 days (N = 127), 32 days (N = 83), and 41 days (N = 65) among college students. However, in post hoc exploratory regressions that included self-efficacy for experience and expression of positive emotions (SEPos), SEDes predicted higher time 2 life satisfaction, but only SEPos uniquely predicted higher time 3 and time 4 life satisfaction.     

The Automaton Self: Defensive organisation,psychodynamics and treatment approaches

Abstract

This paper is not primarily concerned with the content of theory and what we then, in the light of this and of our own experience, say to our clients. Rather, it is concerned with the nature of this knowledge that we are using and that the client in turn uses and experiences in the counselling.

How, or the way in which, we know, defines our knowledge as much as the actual content of that knowledge. The paper delineates two fundamental ways of knowing. One is our ordinary practical and rational way of understanding reality and is usually about achieving some goal – this is what I am calling the product side of counselling: the other is concerned with our more immediate first-hand experiential knowing of ourselves and our world.

The paper opens with a definition of these two kinds of knowledge, product and process, and presents some clinical material to show how these different ways of knowing can have a real effect on the counselling. It then moves on to the question of why counselling trainings are becoming increasingly concerned with product knowledge, and ends with a discussion of how Freud himself was constantly using both ways of knowing as if they were the same, without understanding the implications of this for therapeutic practice.
