An fMRI study on conceptual, grammatical, and morpho-phonological processing

The aim of the present study was to determine whether processing of syntactic word information (lemma) is subserved by the same neural substrate as processing of conceptual or word form information (lexeme). We measured BOLD responses in 14 native speakers of German in three different decision tasks, each focussing specifically on one level of lexical processing (conceptual, syntactic, and morpho-phonological). The test parameters were natural gender, grammatical gender, and word form derivation, respectively. Discrimination between words played backwards and complex sounds served as control task. Complex contrasts revealed a functional fractionation of the left inferior frontal gyrus for each level of lexical processing.     

Examining mental health symptoms in male and female incarcerated juveniles

Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders.     

Dimensions in scales for measuring exploratory tendencies and stimulation levels in consumers: a cross‐cultural comparison of the USA and Spain

Current scales to assess the exploratory tendency are mainly composite measures of psychological characteristics of the consumers concerning their personality. The cultural environment in which they were developed and tested is also a major factor that could affect their validity across different cultural scenes. In this paper the relevant scales measuring exploratory tendencies are reviewed and compared in two different cultural settings: USA and Spain. The main conclusion is that the scales are not equally valid; nor do the items included in them have the same relevance in different cultural setting. Copyright © 2005 John Wiley & Sons, Ltd.     

The Toronto Alexithymia Scale (TAS-20): A measure of general psychological distress

The Toronto Alexithymia Scale (Bagby, R. M., Parker, J. D. A., & Taylor, G. J. (1994). The twenty-item Toronto Alexithymia Scale-I. Item selection and cross-validation of the factor structure. Journal of Psychosomatic Research, 38, 23–32.) is the most commonly used measure of Alexithymia (= difficulties identifying and describing one’s own feelings). Sixty-three persons (34 psychiatric inpatients, 29 healthy controls) first filled in the TAS-20 and were then interviewed about their interpersonal relationships. Two raters coded the emotional experiences that the participants reported during these interviews. Contrary to expectations, participants with higher TAS-20 scores reported more emotions (particularly negative ones), and more different emotions, questioning the validity of the TAS-20 as a measure of Alexithymia. Based on correlation patterns and a joint factor analysis with two well-established measures of psychopathology, it is concluded that the TAS-20 assesses a general psychological distress factor.     

Educational therapy for the failing and frustrated student offender

Methods of treatment are described for meeting the needs of the failing and frustrated student offender. Attention is given to both the public school and juvenile justice setting for the following areas of treatment: classroom management systems, curriculum and instructional adjustment, counseling and support services, and alternative educational programming.     

The effects of movement direction and hemispace on estimates of distance traveled

BACKGROUND/HYPOTHESIS: The degree of attention directed to a stimulus and the presence of anisometric representations can alter the perception of the magnitude of a stimulus. We wanted to learn if normal right-handed subjects' estimates of distance traveled are influenced by the right-left direction or hemispace of movements. METHODS: We had blindfolded participants estimate the distance their arm was moved in a rightward or leftward direction, in right and left hemispace. Since we wanted subjects to estimate the distance traveled rather than compute the distance between the start and finish points, the subjects' arms were passively moved in sinusoidal trajectories at a constant speed. RESULTS: Subjects estimated leftward movements as longer than rightward movements, but there was no effect of hemispace. COMMENTS/CONCLUSIONS: People often attend more to novel than routine conditions and therefore participants might have overestimated the distance associated with leftward versus rightward movement because right-handed people more frequently move their right hand in a rightward direction and learn to read and write using rightward movements. Thus, leftward movements might be more novel and more attended than rightward movements and this enhanced directional attention might have influenced estimates of magnitude (distance).     

Identifying illness perception schemata and their association with depression and quality of life in cardiac patients

The purpose of this paper is to identify groups of cardiac patients who share similar perceptions about their illness and to examine the relationships between these schemata and psychosocial outcomes such as quality of life and depression. A total of 190 cardiac patients with diagnoses of myocardial infarction, stable angina pectoris or chronic heart failure, completed a battery of psychosocial questionnaires within four weeks of their admission to hospital. These included the Brief Illness Perceptions Questionnaire (BIPQ), Beck Depression Inventory II (BDI II) and The MacNew Health-related Quality of Life instrument (MacNew). BIPQ items were subjected to latent class analysis (LCA) and the resulting groups were compared according to their BDI II and MacNew scores. LCA identified a five-class model of illness perception which comprised the following: (1) Consequence focused and mild emotional impact, n?=?55, 29%; (2) Low illness perceptions and low emotional impact, n?=?45, 24%; (3) Control focused and mild emotional impact, n?=?10, 5%; (4) Consequence focused and high emotional impact, n?=?60, 32%; and (5) Consequence focused and severe emotional impact, n?=?20, 10%. Gender and diagnosis did not appear to reflect class membership except that class 2 had a significantly higher proportion of AMI patients than did class 5. There were numerous significant differences between classes in regards to depression and health-related quality of life. Notably, classes 4 and 5 are distinguished by relatively high BDI II scores and low MacNew scores. Identifying classes of cardiac patients based on their illness perception schemata, in hospital or shortly afterwards, may identify those at risk of developing depressive symptoms and poor quality of life.     

Habituación a largo plazo y claves ambientales en humanos

Resumen

Con objeto de comprobar si, como el modelo de Wagner (1976, 1978) postula, durante la habituación a largo plazo se establece una asociación entre el estímulo habituador y las claves ambientales, se llevaron a cabo dos experimentos en humanos. En el experimento I el cambio de contexto ambiental produjo una rehabituación más rápida y una tendencia a una menor recuperación de la respuesta en la segunda situación (empleando un tono de 105 dbs., comienzo súbito y veinticuatro horas de intervalo entre sesiones). En el experimento II (empleando un tono de 80 dbs., comienzo gradual y cuarenta y ocho horas de intervalo entre sesiones), el cambio de contexto ambiental produjo una menor recuperatión de la respuesta y una tendencia a una mayor tasa de habituación. Las instrucciones «informativas» no produjeron habituación diferente de las «normales». Se consideran estos resultados como acordes con una interpretación atencional tradicional de la habituación más que con el modelo de Wagner.     

The Use of the MacAndrew Alcoholism Scale in Detecting Substance Abuse and Antisocial Personality

We evaluated the hypothesis that characterological factors, particularly antisocial personality, influence scores on the MacAndrew Alcoholism Scale (MAC). Using the Washington University research criteria to establish diagnoses, the following subgroups were defined: subjects who received no psychiatric diagnoses; subjects who received diagnoses other than alcoholism, drug dependence, or antisocial personality; and subjects who received a diagnosis of alcoholism, drug dependence, and/or antisocial personality, alone or in combination with other psychiatric diagnoses. The highest MAC scores were obtained by subjects diagnosed as having antisocial personality without alcoholism or drug dependence and subjects diagnosed with antisocial personality, drug dependence, and alcoholism. Alcoholics without antisocial personality or drug dependence, and subjects with other psychiatric diagnoses scored lowest. Although higher MAC scores were obtained by males, MAC scores greater than 24 correctly classified the greatest number of males and females as alcoholic, drug dependent and/or antisocial. These findings are interpreted as consistent with MacAndrew's reinterpretation of the scale as assessing a dimension of personality, rather than solely a tendency to addiction.
