Strategic influence on the time course of predictive inferences in reading

In the present study, we investigated how reading strategies affect the time course of online predictive inferences. Participants read sentences under instructions either to anticipate the outcomes of described events or to understand the sentences. These were followed by a target word to be named, with stimulus onset asynchronies (SOAs) of 500 or 1,000 msec (50- or 550-msec interstimulus interval, respectively). Sentences either were predictive of events or were lexically matched control sentences. There was facilitation in naming latencies for predictable target words in the strategic-anticipation condition at both SOAs, but not in the read-to-understand condition, with a significant improvement in the former condition in comparison with the latter. This suggests that predictive inferences, which are typically considered to be resource demanding, can be speeded up by specific goals in reading. Moreover, this can occur at no cost to comprehension of explicit information, as was revealed by a comprehension test.     

Detailed analysis of the male copulatory motor pattern in mammals: hormonal bases

Data obtained, using a polygraphic technique, on the characteristics of the motor and genital copulatory responses of male rabbits, rats, mice, hamsters, and guinea pigs are reviewed. This methodology provided detailed information, not accessible to other analyses, on the frequency and dynamic organization of copulatory pelvic thrusting trains of the species studied. This comparative analysis showed that: (1) The male rat may display two types of ejaculatory responses, differing in the dynamic organization of the pelvic thrusting train, and in the duration of the intravaginal thrusting period preceding ejaculation. (2) In the guinea pigs and small rodents, but not in rabbits, pelvic thrusting at ejaculatory responses persists during intromission, and a period of fast intravaginal thrusting is associated with ejaculation. (3) The motor copulatory pattern of the rabbit, but not of the rat, hamster, or guinea pig, is affected by castration and hormone treatment, suggesting that, in rabbits, androgen acts both on motivation and on the spinal neural systems related to copulation.     

Shared, not unique, components of personality and psychosocial functioning predict depression severity after acute-phase cognitive therapy

In a sample of 100 patients with recurrent major depression, we collected depression severity data early and late in acute-phase cognitive therapy, plus a wide range of psychosocial variables that have been studied extensively in depression research, including measures of interpersonal, cognitive, and social functioning, and personality traits using an inventory that is linked with the Big-Three tradition in personality assessment theory. By assessing this broad range of variables in a single study, we could examine the extent to which relations of these variables with depression were due to (a) a common factor shared across this diverse set of constructs, (b) factors shared among each type of construct (personality vs. psychosocial measures), or (c) specific aspects of the individual measures. Only the most general factor shared across the personality and psychosocial variables predicted later depression.     

Predicting individual change in support over time among chronically impaired older adults

Hierarchical linear modeling was used to examine the degree of individual change in friendship and family networks and support over time as a function of sociodemographic characteristics, rehabilitation use, and disability. Participants, 449 older adults, had age-related vision loss, a common, chronic impairment that tends to worsen over time. Three interviews were conducted (baseline and 6- and 18-month follow-ups). All network and support variables showed a decrease over time. Regarding factors predicting individual variation, age (younger) and education (lower) were associated with greater baseline friendship support, rehabilitation was related to maintaining a larger friend network, and disability was positively associated with family network and support. Results supported the importance of examining rates of individual change and factors associated with variability in multiple support components by relationship type.     

Differential item functioning: a bibliometric analysis of journals published in Spanish

Differential item functioning: a bibliometric analysis of journals published in Spanish. This study aims to provide an overview of scientific productivity with respect to articles published in Spanish on the issue of DIF. The documents included in the study were identified using the Psicodoc database, as well as the Science Citation Index and Social Science Citation Index from the Web of Science. The analyses carried out are focused mainly on presenting the frequencies and percentages of publications with respect to various bibliometric indicators. The results reveal that interest in the issue of DIF has increased, and that the universities are the most productive institutions. The majority of articles have been published in the journal Psicothema.     

Preventing clinical deterioration in the course of schizophrenia: the potential for neuroprotection

Schizophrenia, which has both genetic and environmental causes, is associated with persistent symptoms and severe functional disability. The illness lies dormant during the premorbid phase and begins to express itself during adolescence or early adulthood. Clinical progression and deterioration reaches a plateau in which the patient is said to be in the chronic phase of illness and at which point restoration of prior functioning is unlikely. The severe deficits associated with schizophrenia are often the result of progression of illness due to lack of appropriate treatment. However, recent advances in neuropsychiatry have led to very early identification of individuals at risk for psychosis, even during the prodromal stage when psychosis has not yet manifested clinically. While research has demonstrated that the efficacy of antipsychotics is limited when used during the chronic phase of illness, these medications can effectively control symptoms and prevent progression of illness when used during the early stages of illness. The evidence of neural degeneration in the pathophysiology of schizophrenic illness suggests that there may be treatment opportunities through neural protection. Neuroprotection, which refers to treatment that helps maintain central nervous system functionality in response to neurobiologic stress, may be responsible for prevention of disease progression and deterioration. In this monograph, Jeffrey L. Lieberman, MD, introduces the phases of schizophrenic illness in relation to the concepts of progression and deterioration. Next, Dolores Malaspina, MD, reviews the neurodevelopmental and neurodegenerative components of schizophrenia. Finally, L. Fredrik Jarskog, MD, focuses on the neuroprotective aspects of therapeutic interventions in schizophrenia.     

Treatment of depression in low-income older adults

The purpose of this study was to compare cognitive-behavioral group therapy (CBGT), clinical case management (CCM), and their combination (CBGT + CCM) to treat depression in low-income older adults (60+). Sixty-seven participants with major depressive disorder or dysthymia were randomly assigned and entered into 1 of the 3 treatment conditions for 6 months. They were followed for 18 months after treatment initiation on depression and functional outcomes. CCM and CBGT + CCM led to greater improvements in depressive symptoms than CBGT, but CBGT led to greater improvements in physical functioning. All 3 conditions resulted in similar reduction of needs. Findings suggest that disadvantaged older adults with depression benefit from increased access to social services either alone or combined with psychotherapy.     

Are cognitive symptoms of schizophrenia mediated by abnormalities in emotional arousal?

We tested 28 individuals with schizophrenia (SZ) and 16 healthy individuals on a test of logical reasoning and "cognitive gating," defined as the ability to discriminate between relevant and irrelevant information in confirming or disconfirming a given belief. The Logical Reasoning and Cognitive Gating Task tests both processes under neutral and affect-laden conditions. This is done by presenting formally identical constructs using benign and emotionally arousing language. When separated by symptom profiles, we found statistically significant differences for performance and arousal response between patients with delusions, patients with formal thought disorder, and patients with neither delusions nor formal thought disorder, as well as between patients and healthy controls. When analyzed by error type, we found that nearly all errors by delusional patients were caused by overly restrictive information choice, a pattern that may be related to a delusional patient's tendency to "jump to conclusions" on Bayesian probabilistic tasks. This is in contrast to patients with formal thought disorder, whose low performance resulted also from overly extensive information choice. The tendencies towards restriction were exacerbated by arousal, which is consistent with studies on cognition and arousal in healthy individuals. After briefly examining research on emotional arousal and SZ, and the interaction between emotional arousal and restriction of perceptual cues in healthy individuals, we conclude by suggesting a model which accounts for the distinctive cognitive characteristics of delusional patients by their possessing distinct vulnerabilities to emotional arousal. Specifically, these results suggest the possibility that delusional patients process information in a manner that is essentially intact. However, delusional patients may possess an acute vulnerability to emotional arousal that might cause delusional individuals to behave cognitively as if they were healthy individuals under significantly more severe forms of stress.     

Psychometric Properties of the Social Phobia and Anxiety Inventory, the Social Anxiety Scale for Adolescents, the Fear of Negative Evaluation Scale, and the Social Avoidance and Distress Scale in an Adolescent Spanish-Speaking Sample

The relationship among several social anxiety measures and a semistructured interview in an adolescent Spanish-speaking sample is examined. Construct validity and test-retest reliability were tested. A principal axis factor analysis was also explored. Results revealed good construct validity and alpha coefficients for the assessment instruments such as the Social Phobia and Anxiety Inventory (SPAI), the Social Anxiety Scale for Adolescents (SAS-A), the Fear of Negative Evaluation Scale (FNES) and the Social Avoidance Distress Scale (SADS). Among these, data strongly support the validity of the Social Phobia and Difference measures of the SPAI and Total SAS-A score as assessment measures in the adolescent population even in non-American cultures and languages. Furthermore, results appear to support the presence of a single higher-order dimension, social anxiety, as measured by the instruments used in this study.     

Appreciation of Beauty and Excellence: Relationship with Personality,Prosociality and Well-Being

Appreciation of beauty and excellence (ABE) is one of the least studied character strengths. Therefore, this study aims at advancing the knowledge in this area by (1) developing a scale that measures the three categories of appreciation (i.e., beauty, moral excellence, and non-moral excellence), (2) assessing many of its psychometric properties, and (3) examining the relationship of ABE with personality, prosociality, and well-being. In Study 1, we create and assess an initial set of items measuring ABE. In Study 2, we examine the dimensionality of ABE, and test the internal consistency and validity of the scale. Moreover, we assess the relationships between ABE and personality, prosociality and well-being. In Study 3, we test the temporal stability of the scale. Results revealed that a three-dimensional model of ABE showed the best fit to the data. The scale showed good validity (construct, factorial, incremental) and reliability (internal and temporal). Finally, ABE yielded positive associations with prosociality and well-being, and demonstrated to be more than a linear combination of the Big Five factors of personality.
