Pursuit gain and saccadic intrusions in first-degree relatives of probands with schizophrenia

Oculomotor functioning of 26 probands with schizophrenia, 12 spectrum and 46 nonspectrum first-degree relatives, and 38 nonpsychiatric control subjects was evaluated. Spectrum relatives had more anticipatory saccades (ASs) and lower pursuit gain than nonspectrum relatives, who had more ASs and lower pursuit gain than control subjects. Probands also had lower pursuit gain than nonspectrum relatives and control subjects but did not differ from other groups on AS frequency. Control subjects had more globally accurate pursuit tracking (root mean square [RMS] error deviation) than both relative groups, whereas probands had the poorest RMS scores. Square wave jerk frequency did not differentiate the groups. Attention enhancement affected the frequency of ASs but did not affect either the other intrusive saccadic event or RMS scores. These results offer evidence that eye-movement dysfunction may serve as a biological marker for schizophrenia.     

Partner influences on sex-associated spoken language of children

Sex-associated features of spoken language were studied in 24 normal White middle-class children ages 4, 8, and 12 years. One hundred utterance units for each subject in conversations of same-sex and mixed-sex dyads of peers were recorded and transcribed. In same-sex dyads, boys talked significantly more about sports and location; girls referred significantly more to school, identity, and wishing and needing. In mixed-sex dyads, girls laughed significantly more, and were significantly more verbally compliant. Boys used significantly more direct requests and sound effects, and talked significantly more about sports in this situation. Major conclusions were that sex of speaker and sex of dyadic partner influence the spoken language of children.This article is based on the author's doctoral dissertation at Teachers College, Columbia University.

Perinatal positive parenting: A follow-up evaluation

In an earlier article (Boger, Richter, & Weatherston, 1983) the Perinatal Positive Parenting Program (PPP) was outlined. The basic tenets of the PPP program were discussed, and an overview of the in-hospital, at-home, and parents' support group components was provided. This article presents the results of a 15-month follow-up evaluation of treatment and control participants in the initial PPP demonstration.     

Extending the search for folk personality constructs: the dimensionality of the personality-relevant proverb domain

College students (95 men and 264 women) rated how well 211 familiar proverbs described their behavior and beliefs. A factor analysis of these data yielded 7 major dimensions; many of the factors were similar to recognized lexical personality factors. Big Five Conscientiousness and Neuroticism were each strongly associated with a single proverb dimension (interpreted as Restraint and Enjoys Life, respectively). Big Five Agreeableness, Extraversion, and Intellect/Imagination were all associated with several proverb dimensions. Agreeableness was most strongly associated with proverb dimensions representing Machiavellian behavior and strong Group Ties, and both Extraversion and Intellect showed particularly notable associations with an Achievement Striving dimension. The 2 remaining proverb dimensions, which represented a belief that Life is Fair and an attitude of Cynicism, could not be accounted for by the Big Five.     

Nonconscious influence of masked stimuli on response selection is limited to concrete stimulus-response associations

A pattern-masked arrow negatively biased the "free choice" between 2 manual responses or between 2 vocal responses. This apparently nonconscious influence occurred only when the free-choice trials were intermixed randomly with other trials that terminated in fully visible arrows, which directed a response of the same modality (manual vs. vocal) as that involved in the free-choice test trials. This indicates that recent conscious processing of the association between specific stimuli and specific responses is needed to activate the nonconscious influence of masked arrows on response selection. Because this influence occurred only when a concrete association was activated, it appears not to be based on deep comprehension of the stimuli and instead is attributable to simple stimulus-response bonds.     

Hope as a Moderator of the Associations Between Common Risk Factors and Frequency of Substance Use Among Latino Adolescents

Ample research suggests that delinquency, depressive symptoms, and peer substance use are common risk factors associated with adolescent substance use. However, the factors that may help to buffer the deleterious effects of these risk factors on adolescent substance use, such as hope, have yet to be examined. The current study evaluated hope as a moderator of the associations between these common risk factors and frequency of substance use (alcohol, tobacco, and marijuana) in a sample of Latino high school students (M _age ?=?16.14 years, SD?=?1.30; 55 % female). Findings indicated that the influence of delinquency on frequency of tobacco and marijuana use depended on levels of hope, with delinquency only positively associated with frequency of use when levels of hope were low. Additionally, hope moderated the association between depressive symptoms and alcohol use, such that depressive symptoms were only positively associated with frequency of alcohol use when levels of hope were low. Results and their implications for intervention are reviewed.     

An empirical solution to the puzzle of weakness of will

This paper presents an empirical solution to the puzzle of weakness of will. Specifically, it presents a theory of action, grounded in contemporary cognitive neuroscientific accounts of decision making, that explains the phenomenon of weakness of will without resulting in a puzzle.     

The cycle of schizoaffective disorder, cognitive ability, alcoholism, and suicidality

In this study we investigated the putative role of cognitive dysfunction, diagnosis (schizoaffective versus schizophrenia disorder), and alcoholism as risk factors for suicidal behavior among individuals with DSM-TV schizophrenia or schizoaffective disorders. Subjects received cognitive tests and medical records were reviewed for evidence of a history of suicide attempts or suicidal ideation. Discriminant analysis was used to identify cognitive test performance measures that distinguished those with versus those without suicidal behavior. None of the cognitive measures discriminated between the two groups. The rates of suicidal behavior (suicidal ideation and suicide attempts) did not differ between participants with versus those without comorbid alcohol use. An association was found between suicidal behavior and the diagnosis of schizoaffective disorder. It was concluded that the history of prominent mood syndromes characteristic of schizoaffective disorder contributes to increased risk of suicidal behaviors. Cognitive dysfunction and/or alcoholism did not contribute additionally to risk in this study.
