Mechanisms of verbal memory impairment in four neurodevelopmental disorders

Profiles of verbal learning and memory performance were compared for typically developing children and for four developmental disorders characterized by different patterns of language functioning: specific language impairment, early focal brain damage, Williams Syndrome, and Down Syndrome. A list-learning task was used that allowed a detailed examination of the process of verbal learning, recall, and recognition (California Verbal Learning Test--Children's Version). Distinct patterns of performance characterized the four disorders. These patterns were consistent with the language deficits typically seen in the disorders, with the exception of a dissociation seen in Williams Syndrome.     

Sex and personality traits influence the difference between time taken to tell the truth or lie

A necessary component of lying is the withholding of a truthful response. Hence, lying may be conceptualised as involving the inhibition of an initial, automatic response (the truth) while an alternative response (the lie) is generated. We investigated response times to visually and auditorially presented questions probing recent episodic memory, when subjects answered questions truthfully or with lies. We also investigated whether the absolute response times or difference between time taken to tell the truth or lie was affected by participants' sex or correlated with personality scores on the Eysenck Personality Questionnaire Revised-Short Scale. 61 subjects answered the same 36 questions five times. The first time involved answering all questions truthfully, which allowed post hoc analysis of whether subjects had been consistent in their lying and truth-telling on the following four occasions. These latter four occasions involved answering all questions (one each with 'truth' or 'lie') for both types of presentation. Regardless of type of presentation or subjects' sex, subjects took approximately 200 msec. longer to lie than to tell the truth in response to each question (p<.001). There were significant correlations between truthful response times to auditorially presented questions and Eysenck 'Neuroticism' scores. There was also a significant correlation for women between mean individual lie-minus-truth time to auditorially presented questions and Eysenck 'Lie' scores. These preliminary data suggest that response time is systematically longer when telling a lie and that personality variables may play a part in this process.     

The influence of job familiarity and impression management on self-report measure scale scores and response latencies

Two studies were conducted to examine the effects of job familiarity and impression management on response latencies and scale scores for measures of personality and situational judgment. In a laboratory study using university students and a field study using U.S. Border Patrol Agent applicants, impression management was generally associated with faster personality item responses when job familiarity was high and with slower responses when job familiarity was low. Both impression management and job familiarity were associated with personality item responses that were more likely to lead to a job offer. The field study revealed a similar pattern of results for situational judgment scale response latencies, although only impression management was associated with item responses that were more likely to lead to a job offer. The implications for using response latencies to detect impression management on self-report measures are discussed.     

The role of local context in autoshaping

Three experiments used an autoshaping procedure with pigeons to examine the effects of nonreinforced, nontarget stimuli (ITI-fillers) during the intertrial interval on responding to a reinforced target CS. Experiment 1 replicated a previous demonstration that an ITI-filler that occupied a substantial portion of the ITI attenuated responding to the target CS relative to a group trained with a similar ITI but lacking the ITI-filler. Experiment 2 found that the superiority of responding typically found with a long ITI relative to a short ITI, that is, the trial-spacing effect, can be reversed by imposing a filler stimulus during the ITI in the former condition. Experiment 3, using a within-subject design, found that when one background stimulus condition occupied a majority of the interreinforcement interval, pairings of one target CS with reinforcement that were embedded within this background condition, that is, a long duration local context occurred for this CS, yielded better performance that a second, reinforced, target CS paired with reinforcement in the shorter duration background condition. These results confirmed predictions derived from a local context view of cycle time. Comparator theories of classical conditioning require incorporation of this notion into their conceptualization of effective cycle time in order to explain the present findings.     

Sexual harassment of university students

The sexual harassment of junior, senior, and graduate student women and men by male and female professors, graduate assistants, and staff was investigated to determine students' personal experiences in the classroom, outside the classroom, and in job-related settings. Usable survey responses were returned by 393 students, and incidents were detailed by 38 women and 9 men who noted their responses to the harassment and its effects. Attitudes toward and acceptance of sexually harassing behaviors were measured by a 10-item Tolerance for Sexual Harassment Inventory (TSHI). The frequency of initiation of sexual behaviors was also assessed. More women than men reported being sexually harassed. Male and female perceptions of classroom behaviors were in agreement for most items. Men and women differed significantly on the TSHI, with men more tolerant of sexual harassment than women, and highly significant age differences were found, indicating a greater acceptance of sexual harassment by younger students. There was little difference between male and female students in the frequency of their initiating sexual behaviors. The TSHI was assessed; reliability coefficients and a factor analysis are presented.This research was supported by a grant from the College of Arts and Sciences.

Sex Differences in Visual Recognition Memory: Support for a Sex-Related Difference in Attention in Adults and Children

The selectivity hypothesis of Meyers-Levy (1989) proposes that cognitive sex differences reflect underlying differences in information processing between males and females. Males are considered to be more likely to organize information in a self-related manner, whereas females are more likely to adopt a comprehensive approach to information processing. We tested this hypothesis in children (10–15 years) and adults using recognition memory tasks. Tests were devised which employed male-oriented objects, female oriented objects, or random objects. In both the child and adult samples, females performed significantly better than males on tests using random and female-oriented objects. Males performed at the level of females only when tested for recognition of male-oriented objects. These results demonstrate that this sex difference is present prior to puberty and support the concept of sex differences in information processing.     

Inter‐confessional relations in nineteenth‐century Syria: Damascus,Homs and Hama compared

This article examines relations between Muslims and Christians in Syria during the later Ottoman period in light of social science literature on ethnicity and ethnic conflict. It argues that the social science literature illuminates the historiography of this question by bringing to the fore historians’ underlying assumptions about religion and ethnicity. By comparing three Syrian towns with contrasting histories of inter‐communal relations, the article argues that religious consciousness in Syria ought not to be understood in strictly primordialist terms. Rather, a more circumstantialist approach is needed where specific conditions transform an otherwise unproblematic situation of religious diversity into one of inter‐confessional hatred and strife.
