Electrophysiological indices of brain activity to "the" in discourse

In a first experiment, we recorded event-related-potentials (ERPs) to "the" followed by meaningful words (Story) versus "the" followed by nonsense syllables (Nonse). Left and right lateral anterior positivities (LAPs) were seen from the onset of "the" up to 200 ms in both conditions. Later than 200 ms following the onset of "the", the left and right LAPs continued for "the" in the Story, but were replaced by a negativity in the Nonse Condition. In a second experiment, ERPs were recorded to "the" in the Story and Nonse contexts mixed together under two different task instructions (attend to the auditory stimuli versus ignore the auditory stimuli). The same pattern of findings as Experiment 1 were observed for the Story and Nonse contexts when the participants attended to the auditory stimuli. Ignoring the auditory stimuli led to an attenuation of the right LAP, supporting the hypothesis that it is an index of discourse processing.     

Involvement in Meaningful Activities and Self-Reported Aggression and Delinquency Among Inner-City Teenagers

Ninth grade students from an inner-city high school (n = 163) completed self-report measures assessing their participation in meaningful activities, behavioral problems, and locus of control. In multivariate analyses, Gender × Activity Level interaction effects were shown: males with higher levels of meaningful activity had significantly lower scores on aggression and delinquent behavior subscales than males with lower levels of meaningful activity. However, this relationship was not shown for females. Of youth who reported clinically significant levels of aggression and/or delinquency, females reported significantly higher levels of meaningful activities than males. Gender differences in findings and future research directions are discussed.     

A test of foreign language acquisition: paired‐association learning

This experiment investigated college student difficulties with foreign language acquisition. We developed a word‐sound, paired‐associates learning test that discriminated 92% of the control participants and 95% of the experimental participants. The results are interpreted in terms of an associative model of foreign language learning disability. We discuss how to integrate the test into a larger diagnostic battery for predicting the facility with which a person will be able to learn a foreign language.

A note on stove and adding machine arrangement preferences as a function of sex and handedness

Some stove and adding machine arrangements chosen by our subjects were influenced by both their sex and handedness.     

Relation of the Big Five to Biodata and aspects of the self

Two studies examined McCrae and Costa’s system model of personality. Their model suggests the Big Five should have relatively strong associations with life history (measured in Study 1 by Biodata) and with Self-Concept (measured in Study 2 by various Self questionnaires). Study 1—210 participants (143 females) completed Bipolar Big Five Markers and a Biodata inventory. Factor Analyses confirmed the Big Five and revealed seven viable Biodata factors. Multiple regression revealed that most Biodata factors were predicted well by 2 or more Big Five traits. Study 2—199 participants (125 females) completed Bipolar Big Five Markers and an omnibus Self inventory consisting of six previously developed scales. Factor Analyses confirmed the Big Five and revealed eight viable Self factors. Multiple regression revealed that the Self factors were also predicted fairly well by two or more Big Five traits.Both studies found relatively strong associations between the Big Five and the Biodata and Self factors, which lends support to McCrae and Costa’s system model of personality. A consistent pattern of both a primary and secondary trait as joint predictors of Biodata and Self factors suggests that these areas are systematically influenced by multiple traits rather than only single traits.
