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.     

Assisting At-Risk College Students With Attributional Retraining and Effective Teaching1

Attributional retraining appears to be an effective remedial intervention for college students. However, the potential moderating effects of student and classroom characteristics have not yet been investigated systematically. In two studies, attributional retraining was provided to low- and high-risk students, followed by a videotaped lecture presented by either an ineffective or effective instructor. Attributional retraining enhanced achievement on a lecture-based achievement test only when combined with effective teaching, improving the achievement of students who had previously performed poorly (Experiment l), and of low-achieving externals (Experiment 2). The intervention provided no advantage for previously successful students and low-achieving internals. Moreover, attributional retraining induced a more internal attribution profile in students with an external locus, and increased expectations of future success in both externals and internals, but again only when students also received effective instruction. These results suggest that contextual factors related to the classroom, such as quality of instruction, and individual differences have to be considered when developing attributional retraining programs.

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. Special thanks are extended to the dissertation sponsor, Edward Mysak, and committee members, Lois Bloom and Mary Parlee, for their generous guidance and support. Appreciation is also expressed to Mark Kesselman, Owen Whitby, Eleanor Morrison, Chester Mazur, Charles Elliott, Fred Maulucci, and Anthony Robinson for their suggestions and participation.

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.     

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.     

Negative priming effects in children engaged in nonspatial tasks: evidence for early development of an intact inhibitory mechanism

Three experiments are reported that examined conceptual negative priming effects in children 5 to 12 years of age. Experiment 1 used a negative priming variant of a flanker task requiring the naming of a central color blob flanked by irrelevant distractors. Experiment 2 used a negative priming variant of the Stroop color-word task. Experiment 3 used a same-different matching task with novel 3-D shapes. Results revealed significant and equivalent magnitudes of negative priming across the tested age groups for all 3 tasks. It is concluded that the inhibitory mechanism underlying conceptual (i.e., identity or semantic) negative priming in visual selective attention tasks is intact in young children. Because the findings and conclusions diverge from the developmental literature on negative priming, the authors attempt to reconcile the contradictions by pinning down the reasons for the discrepancies.
