Psychometric Validation of the Preschool Outcome Questionnaire: A Preschool Treatment Outcome Instrument

Developing normed treatment outcome measures is important to research addressing treatment effectiveness and to improved clinical care. The Preschool Outcome Questionnaire (POQ) is a new measure designed for use with preschool children aged two to six. Designed in collaboration with parents and clinicians, the POQ is brief, easy to administer, score and interpret. This study reports on the instrument’s psychometric evaluation, contains preliminary normative data, and provides a clinical cut-off and a reliable change index to facilitate clinical use of the instrument. Results show that the POQ has acceptable test–retest and internal reliability, concurrent validity and criterion validity. Importantly, results also show that the instrument is sensitive to clinically relevant change. Clinical implications are discussed as well as suggestions for further research.     

Addressing Cultural Variables in Parent Training Programs With Latino Families

There has recently been increased attention given to understanding how cultural variables may have an impact on the efficacy of treatments with Latino families seeking psychological services. Within parent training programs, understanding the extent to which culture can affect parenting practices is vital to providing quality care. The focus of this article is to discuss how different cultural variables such as respeto, personalismo, machismo, marianismo, and acculturation can impact the efficacy of parent training programs for Latino families. Recommendations for addressing these cultural variables in parent training programs are provided.     

《上帝:一切虚构作品中最令人不快的形象》

正作者从基督教福音派牧师转变为坚定的无神论者,被认为比很多基督徒和无神论者能更好地理解《圣经》。上帝的形象是怎样的?仁慈,公正,宽容?本书通过圣经《旧约》和《新约》的文本考察,却详细论证了:他妒忌(jealous)、不公正(urimjust)、残忍(malevolent)……并没有多少令人羡慕的品格。在英美,一些人信仰基督教多年却并未读过圣经,读过此书,认为:基督徒应该自己阅读圣经,更应该阅读此书,     

Peer support critical elements and experiences in supporting the homeless: A qualitative study

Peer supporters are individuals with lived experience and are an integral part of health care systems, providing support to those affected by various phenomena such as homelessness and addictions. However, little is known about the critical elements that underpin peer support interventions. This qualitative study sought to understand the critical elements of intentional peer support with a homeless population, voiced by those who provide and/or receive this support. Twenty‐nine participants from 4 different homeless charities in England were interviewed about their experiences of providing/receiving peer support and what they felt were critical factors to its success. Participants defined peer support as an experience‐based relationship, built upon mutual understanding, empathy, and support. Thematic analysis was utilised to in developing 6 themes. Results identified peers' persistence in developing unique experience‐based relationships, providing social support, role modelling recovery, and peers' motivations were perceived as important factors involved in peer support. It was also found that peers described benefitting from helping, such as, undergoing transformative identity developments that helped them to escape homelessness. Through the retelling of their stories, they create meaning and restructure their autobiography, attributing experiences of homelessness as a catalyst for positive changes in their lives. Limitations and future research are discussed.     

A standardized list of affect-related life events

In experimental contexts, affect-related word lists have been widely applied when examining how cognitive processes interact with emotional processes. These lists, however, present limitations when studying the relation between emotion and cognitive processes such as time and number processing because affective words do not inherently contain time or quantity information. Live events, in contrast, are experienced by an observer and therefore inherently carry affect information. Unfortunately, existing life-event lists and inventories have been largely applied within clinical contexts as diagnostic tools, and therefore are not suitable for many experimental contexts because they do not contain a balanced number of reliably positive, negative, and neutral life events. In Experiment 1, we create a standardized affect-related life-events list with 171 positive, negative, and neutral affect-related life events. In Experiment 2, we show that strength of affect and significance of the event are integral dimensions, suggesting that these two features are difficult to separate perceptually. The implications of these findings and some potential future applications of the created life-events list are discussed.     

Reperfusion of Specific Brain Regions by Raising Blood Pressure Restores Selective Language Functions in Subacute Stroke

We report a series of six single subject studies examining the effects of pharmacological blood pressure elevation on regional brain perfusion and language function. Previous reports indicate that hypoperfusion of specific brain regions, as delineated by magnetic resonance perfusion weighted imaging (PWI), is associated with disruption of selective lexical functions. On this basis, we hypothesized that reperfusion of the same regions, in the absence of infarct in that region, would restore the associated lexical function. We present five patients with impaired lexical-semantics associated with poor perfusion, but not infarction, of Brodmann's area 22 (BA 22), and one patient with impaired lexical-semantics and a superimposed deficit in retrieving the phonological representations of words, associated with poor perfusion Brodmann's area 37 (BA 37) as well as BA 22. Each patient was treated with induced blood pressure elevation to increase perfusion of the ischemic and dysfunctional tissue. Daily testing of naming and comprehension, with stimulus sets matched for frequency, familiarity, and length, showed improved lexical-semantics in the patients who showed reperfusion of BA 22 and improved oral naming (but not lexical-semantics) in the patient who showed reperfusion of BA 37. These cases illustrate that loss of function with hypoperfusion of a circumscribed area of the brain, and recovery of the same function with improved perfusion of that brain region, can reveal brain/language relationships prior to reorganization after brain injury.     

Statistical modelling of gaze behaviour as categorical time series: what you should watch to save soccer penalties

Previous research on gaze behaviour in sport has typically reported summary fixation statistics thereby largely ignoring the temporal sequencing of gaze. In the present study on penalty kicking in soccer, our aim was to apply a Markov chain modelling method to eye movement data obtained from goalkeepers. Building on the discrete analysis of gaze employed by Dicks et al. (Atten Percept Psychophys 72(3):706–720, 2010b), we wanted to statistically model the relative probabilities of the goalkeeper’s gaze being directed to different locations throughout the penalty taker’s approach (Dicks et al. in Atten Percept Psychophys 72(3):706–720, 2010b). Examination of gaze behaviours under in situ and video-simulation task constraints reveals differences in information pickup for perception and action (Attention, Perception and Psychophysics 72(3), 706–720). The probabilities of fixating anatomical locations of the penalty taker were high under simulated movement response conditions. In contrast, when actually required to intercept kicks, the goalkeepers initially favoured watching the penalty taker’s head but then rapidly shifted focus directly to the ball for approximately the final second prior to foot-ball contact. The increased spatio-temporal demands of in situ interceptive actions over laboratory-based simulated actions lead to different visual search strategies being used. When eye movement data are modelled as time series, it is possible to discern subtle but important behavioural characteristics that are less apparent with discrete summary statistics alone.     

The Cognitive Structure of Scientific Revolutions

For historical epistemology to succeed, it must adopt a defensible set of categories to characterise scientific activity over time. In historically orientated philosophy of science during the twentieth century, the original categories of theory and observation were supplemented or replaced by categories like paradigm, research program and research tradition. Underlying all three proposals was talk about conceptual systems and conceptual structures, attributed to individual scientists or to research communities, however there has been little general agreement on the nature of these structures. Recent experimental research in cognitive science has considerably refined the theory of concepts. Drawing upon the results of that research, philosophers can construct more concrete and empirically defensible representations of conceptual systems. I will suggest that this research supports a modest and useful sense of both normal and revolutionary science, not as epistemological continuities or discontinuities, but as particular patterns of conceptual change.     

Towards closure on closure

Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories of knowledge.
