Space and Time in the Child's Mind: Evidence for a Cross-Dimensional Asymmetry

What is the relationship between space and time in the human mind? Studies in adults show an asymmetric relationship between mental representations of these basic dimensions of experience: Representations of time depend on space more than representations of space depend on time. Here we investigated the relationship between space and time in the developing mind. Native Greek‐speaking children watched movies of two animals traveling along parallel paths for different distances or durations and judged the spatial and temporal aspects of these events (e.g., Which animal went for a longer distance, or a longer time?). Results showed a reliable cross‐dimensional asymmetry. For the same stimuli, spatial information influenced temporal judgments more than temporal information influenced spatial judgments. This pattern was robust to variations in the age of the participants and the type of linguistic framing used to elicit responses. This finding demonstrates a continuity between space‐time representations in children and adults, and informs theories of analog magnitude representation.     

Psychopathological Symptom Dimensions in Patients with Gastrointestinal Disorders

The current study aims to investigate the factorial validity of a widely used psychopathological rating scale, the Symptom Check List-90-R (SCL-90-R), in a group of patients suffering from gastrointestinal disorders, and to determine the specific psychopathological profiles that characterize the individual patient subgroups. Patients suffering from either irritable bowel syndrome, ulcerative colitis, non-erosive reflux disease or erosive reflux disease completed the SCL-90-R at a tertiary care gastroenterology department. Seven factors were identified, with one major distress factor and six minor factors. Comparison of the gastrointestinal disorder subgroups indicated that irritable bowel syndrome patients exhibited significantly more psychological distress compared to the other groups, and that gastrointestinal patients as a group, compared to healthy controls, were characterized by high levels of irritable depression and somatization. In planning further studies we encourage the use of factors identified in our study. The treatment of substantial irritable depression can be an important factor in improving quality of life in patients suffering from gastrointestinal disorders.     

The Normal,Improving, and Productive Self: Unpacking Neoliberal Governmentality in Therapeutic Interactions

Psychotherapy might be seen as a site of reproduction of neoliberal capitalist ideology. Unpacking therapeutic discourse affords the opportunity to explore neoliberalism in operation. We present a theoretical case for exploring neoliberalism in the therapeutic context. Specifically, we identify and illustrate three neoliberal discourses: the normal self, the improving self, and the productive self. We discuss how therapists might orient to these discourses and identify ways to challenge neoliberal ideology. Doing so will not dismantle power systems that yield oppression; however, it may help clients reclaim and negotiate preferred subjectivities within this system while also working toward broader social justice.     

Scaling questions: asking and answering them in counselling1

Solution-focused counsellors use “scaling questions” to construct understandings of clients’ concerns and solutions to them. We examine how these questions are asked and answered, offering evidence of what is constructed from within counselling discourse. Also, clients and counsellors offer their retrospective accounts of their participation in question and answer sequences in their dialogues. We conclude by speaking to the implications we see from this research as it relates to collaborative and resourceful dialogue between counsellors and clients.     

Constraints on enhanced extinction resulting from extinction treatment in the presence of an added excitor

Three Pavlovian fear conditioning experiments with rats as subjects explored the effect of extinction in the presence of a concurrent excitor. Our aim was to explore this particular treatment, documented in previous studies to deepen extinction, with novel control groups to shed light on the processes involved in extinction. Relative to subjects extinguished on the target CS alone, Experiments 1 and 2 found across a range of parameters that any appreciable effect of facilitated extinction due to the concurrent excitor was submerged by generalization decrement going from extinction to testing. In Experiment 3 we used different durations for the target and concurrent stimuli in order to discourage configuring and an ABC renewal design to increase sensitivity, and observed diminished renewal resulting from extinction in the presence of a second excitor. Our findings suggest that there are distinct limits to the observation of enhanced extinction in the presence of an excitor and identifies some of the sources of these limitations.     

Exploring and Estimating the Revenues and Profits of Participants in Stolen Data Markets

Researchers have begun to explore the problem of mass data breaches, where consumer information is acquired by cybercriminals and sold in open markets on-line. Although studies document the social processes of the market and relationships between buyers and sellers, few have considered the revenues earned from market transactions. This study explored these issues using a sample of threads from 10 Russian language and 3 English language Web forums used to sell stolen data. Estimates were generated on the total number of transactions completed by participants along with the advertised prices for the two most common forms of personal information sold. The findings demonstrated that buyers may earn a range of revenues from the sale of stolen data, although this figure was smaller than the potential profits earned from fraudulent use and identity crimes by data buyers. The implications of this study for cybercrime research and policy are explored in detail.     

A Comparison of Posttraumatic Growth After Acquired Brain Injury or Myocardial Infarction

Posttraumatic growth (PTG) is known to occur following acquired brain injury (ABI). It is not yet known to what extent PTG experiences following ABI are unique to the neurological nature of the injury. We investigated PTG in survivors of ABI or myocardial infarction (MI); MI is comparable to ABI but does not have a primary neurological element. Thirty-three ABI survivors (age M = 51.6, SD = 12.4; 52% male; years since injury M = 5.5, SD = 5.3) and 47 MI survivors (age M = 66.4, SD = 9.9; 79% male, years since injury M = 9.9, SD = 8.6) completed a survey including the Posttraumatic Growth Inventory (PTGI). Unadjusted analyses showed no significant group differences on PTGI total score (ABI M = 54.0, SD = 19.6; MI M = 54.6, SD = 23.6; d = .03, p = .902) or on any of the five subscales, but analyses adjusted for covariates showed that scores on “Relating to others” were higher in participants with ABI (unstandardized coefficient = 5.43; 95% CI .27, 10.60; p = .039). Open-ended comments revealed aspects of growth in both samples that were not directly captured by the five PTGI factors.     

Thermal behaviour of polystyrene/silica composites

The particle-size distribution in silica powder prepared by the sol–gel method has been determined by dynamic light scattering analysis. The average diameter of the particles was found to be 250?nm. Using a low-temperature nitrogen adsorption–desorption technique, it was found that the synthesised powder may be referred to as mesoporous materials. Polystyrene/silica composite films were fabricated by casting from o-xylene solutions. It was found, using thermogravimetry, that incorporation of silica leads to an increase in both the onset temperature of polymer degradation and in the temperature at which the maximum rate of weight loss occurs. Using differential scanning calorimetry, the phase transitions from the glassy state to the elastic one were studied for the polymeric materials. New data relating to the effect of silica on the glass-transition temperature, T_g, of composites with a low weight fraction of SiO₂ were found. Specifically, we found a non-monotonic concentration dependence of the value of T_g. The present results advocate for employing silica as an effective filler for producing polymer composites with enhanced thermal properties.     

Biased perception of overeating in bulimia nervosa and compulsive binge eaters

This study investigated the relationship between caloric intake and perceived overeating in subjects with and without a history of problematic binge eating. Eighty subjects (20 in four groups: bulimia nervosa, compulsive binge eaters, obese, and normal controls) self-monitored eating for 2 weeks. The regression slopes for self-reported overeating as a function of caloric intake were contrasted across the four groups. At higher caloric levels, bulimics and binge eaters reported overeating at a significantly higher rate compared to obese and normal control groups. These data were interpreted as a type of cognitive bias whereby subjects with a history of binge eating distorted their perception of overeating at progressively higher caloric levels. It was proposed that excessive concern about eating and dieting may cause such cognitive biases. A parallel was drawn with body image distortion, which appears to be associated with overconcem with body size and shape.
