“The Turkish minority in Bulgaria”: A clarification

These short notes are not meant to justify the recent repression of the Muslims in Bulgaria; rather, they try to explain them objectively and in all their aspects, including external conditions and factors. Dr. Michel, the author of the article here examined, has worked on a rich data base in the form of history and chronicle of events. And yet he gives the impression of floating on the surface of things and here and there presents somewhat one‐sided and subjective evaluations. Using and quoting as evidence material mainly from the Turkish side he deprives the article in question of the objectivity and impartiality that are obligatory for scholarly research. I am very grateful for the opportunity of having access to Dr. Michel's article in advance of its publication and for being invited to present and interpret the interrelations of Muslims and Christians of Bulgaria in recent times from my point of view.     

Relationship between the Delay Task and Rating Scale measures of Inattention and Hyperactivity

A group of 187 elementary school children were administered a microcomputer version of the Delay Task (Gordon, 1979) in which responses were reinforced only when they followed the preceding response by at least 6 seconds. They were also rated on the Conners Teacher Rating Scale (CTRS) by their classroom teacher. Performance on the Delay Task was not correlated with any of the CTRS subscales for the overall sample. Sex differences were found in the Conduct, Inattention, and Hyperactivity factors of the CTRS. No sex difference was found for performance on the Delay Task. When performance on the Delay Task was correlated with the four CTRS factors by sex, correlations between the Delay Task and the inattention subscale and hyperactive subscale were significant only for the male subsample. Implications of the findings for assessment of hyperactivity are discussed.The research was supported by an equipment grant from the University of Auckland Research Committee.

The effect of high ambient temperature on timing behavior in rats

The present experiments demonstrated a reliable within-session increase in rectal temperature (T(re)) at 25 degrees C during stable differential-reinforcement-of-low-rate (DRL) performance. The thermal response was found to be independent of the DRL value and reinforced DRL performance, but dependent on the state of the animal's deprivation. Exposure to a 35 degrees -C environment increased the post-session T(re) significantly above the 25 degrees -C post-session T(re) for seven of eight subjects. Response and reinforcement rate at 35 degrees C was found to be independent of DRL value, although it decreased as DRL value increased at 25 degrees C. A discriminative stimulus used to mark the end of the interval increased the reinforcement rate at 25 degrees C but provided no advantage at 35 degrees C. Measurement of the pattern of responding during DRL performance revealed increases in the proportion of long interresponse times at 35 degrees C. Reinforcement rate was found to decrease progressively at 35 degrees C, reaching a minimum within 40 to 50 min of the 90-min session. Visual observation of overt behaviors during DRL performance at 35 degrees C revealed a reduction in the frequency of overt behavior, characteristic of 25 degrees -C performance, and a time-dependent increase in the probability of an alternative set of behaviors.     

Use of Occupational Drawings to Enhance Vocational Development

Missing in the literature regarding the teaching of occupational information are techniques involving the use of materials created by the students themselves. The method of utilizing the students' occupational drawings was compared to the traditional method taught in group guidance classes. The criterion instrument was developed, pre- and post-measures secured for both groups, and the statistical significance at .0005 level was computed between the experimental and the control group, favoring the experimental group.     

Patient Personality and Relational Patterns in Psychotherapy: Factor Structure,Reliability, and Validity of the Psychotherapy Relationship Questionnaire

The aim of this study was to examine the factor structure and the psychometric properties of the Psychotherapy Relationship Questionnaire (PRQ; Bradley, Heim, &; Westen, 2005 Bradley, R., Heim, A. K., &; Westen, D. (2005). Transference patterns in the psychotherapy of personality disorders: Empirical investigation. The British Journal of Psychiatry, 186, 342–349. doi:10.1192/bjp.186.4.342[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), a clinician report instrument that measures a wide spectrum of thoughts, feelings, motives, conflicts, and behaviors expressed by patients toward their therapists in psychotherapy. A national sample of psychiatrists and clinical psychologists (N = 314) of different theoretical orientations completed the PRQ, as well as the Shedler–Westen Assessment Procedure–200 (SWAP–200; Westen &; Shedler, 1999a Westen, D., &; Shedler, J. (1999a). Revising and assessing Axis II, Part I: Developing a clinically and empirically valid assessment method. The American Journal of Psychiatry, 156, 258–272.[PubMed], [Web of Science ®] , [Google Scholar], 1999b Westen, D., &; Shedler, J. (1999a). Revising and assessing Axis II, Part I: Developing a clinically and empirically valid assessment method. The American Journal of Psychiatry, 156, 258–272.[PubMed], [Web of Science ®] , [Google Scholar]) to assess the personality of a patient in their care. Factor-analytic procedures identified 6 transference dimensions that showed excellent internal consistencies: (a) hostile, (b) positive/working alliance, (c) special/entitled, (d) anxious/preoccupied, (e) avoidant/dismissing attachment, and (f) sexualized. Factor scores were significantly related to patients’ personality characteristics and psychological functioning, regardless of the clinicians’ orientations. The findings support that the PRQ is a valid and reliable tool for evaluating the patients’ relational patterns emerging in clinical practice in a clinically coherent and psychometrically robust way. Clinicians’ careful understanding of these patterns can be very useful for making accurate diagnostic formulations, as well as for providing a roadmap for effective therapeutic intervention.     

HPA-Axis Activation as a Key Moderator of Childhood Trauma Exposure and Adolescent Mental Health

Individual differences in a child’s sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n?=?121, ages 9–16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child’s trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments.     

Computerized cognitive training during physical inactivity improves executive functioning in older adults

The hippocampus is closely tied to spatial navigation, a central component in cognitive functioning, and critically involved in age-associated cognitive decline and dementia. This study evaluated a novel, cognitive computerized spatial navigation training (CSNT) program targeting the hippocampus, with expectation of mitigating possible cognitive decline with bed rest (BR). During a 14-day BR study with 16 healthy, older men (mean age = 60 ± 3, range = 55–65 years), half received CSNT for 12 days in 50-min sessions and half were controls (watching documentaries). This design uniquely controlled diet, sleep, and other personal and environmental activities. Although there were no cognitive declines in controls post-BR, CSNT participants demonstrated significant increases in executive/attention ability and processing speed, and continued spatial navigation testing showed improvement to 400 days post-BR. This intervention may prove useful to mitigate cognitive declines known to occur in long periods of immobilization and could have broader implications in protecting against age-related cognitive decline.     

Evaluating risk propensity using an objective instrument

Risk propensity is the stable tendency to choose options with a lower probability of success, but greater rewards. Its evaluation has been approached from various perspectives: from self-report questionnaires to objective tests. Self-report questionnaires have often been criticized due to interference from voluntary and involuntary biases, in addition to their lack of predictive value. Objective tests, on the other hand, require resources that make them difficult to administer to large samples. This paper presents an easy-to-administer, 30-item risk propensity test. Each item is itself an objective test describing a hypothetical situation in which the subject must choose between three options, each with a different gain function but equivalent in expected value. To assess its psychometric fit, the questionnaire was administered to 222 subjects, and we performed a test of its reliability as well as exploratory factor analysis. The results supported a three-factor model of risk (Sports and Gambling, Long-term Plans, and Loss Management). After making the necessary adjustments and incorporating a global factor of risk propensity, confirmatory factor analysis was done, revealing that the data exhibited adequate goodness of fit.     

The interplay of spatial attention and memory: evidence for memory-driven spatial compatibility effects, but not for a facilitating role of attention in memory retrieval

The visual indexing theory proposed by Zenon Pylyshyn (Cognition, 32, 65-97, 1989) predicts that visual attention mechanisms are employed when mental images are projected onto a visual scene. Recent eye-tracking studies have supported this hypothesis by showing that people tend to look at empty places where requested information has been previously presented. However, it has remained unclear to what extent this behavior is related to memory performance. The aim of the present study was to explore whether the manipulation of spatial attention can facilitate memory retrieval. In two experiments, participants were asked first to memorize a set of four objects and then to determine whether a probe word referred to any of the objects. The results of both experiments indicate that memory accuracy is not affected by the current focus of attention and that all the effects of directing attention to specific locations on response times can be explained in terms of stimulus-stimulus and stimulus-response spatial compatibility.
