E-nabled for E-Learning? The Moderating Role of Personality in Determining the Optimal Degree of Learner Control in an E-Learning Environment

This paper investigates the moderating role of specific Big Five personality traits on the relationship between learner control and training performance in an e-learning environment. Specifically, we examined the role of openness to experience, conscientiousness, and extraversion. Participants completed a video-based e-learning program with either a high or low level of learner control. Results demonstrated that the personality traits of openness to experience and extraversion moderated the relationship between learner control and training performance. Specifically, training performance was higher for trainees higher in openness and extraversion when they were in an environment with high learner control versus low learner control. Conversely, for trainees lower in these traits, performance was higher with low learner control versus high learner control. Future research and practical applications are discussed.     

An Inventory of Affective Tolerance

The two dimensions of personality, extraversion (E) and neuroticism (N) as measured by the Eysenck Personality Inventory (EPI), were tested for their social desirability response set and their independence. Results from a collegiate sample (N = 282) show that E and N scales were susceptible to social desirability response bias for males and females, respectively. This bias could not be overcome by eliminating Ss who reported higher scores on the lie scale included in the EPI. The dimensionality of the two scales for the male Ss is questionable.     

Individual differences in pathogen disgust predict men’s,but not women’s,preferences for facial cues of weight

Previous research suggests that people who score higher on measures of pathogen disgust demonstrate (1) stronger preferences for healthy individuals when assessing their facial attractiveness and (2) stronger negative attitudes about obese individuals. The relationship between pathogen disgust and attractiveness judgments of faces differing in cues of weight has yet to be investigated, however. Here we found that men’s, but not women’s, pathogen disgust was positively correlated with their preference for facial cues of lower weight. Moreover, this effect of pathogen disgust was independent of the possible effects of moral and sexual disgust. These data implicate pathogen disgust in individual differences in preferences for facial cues of weight, at least among men, and suggest that the sex-specific effects of pathogen disgust on preferences for facial cues of weight may be different to those previously reported for general negative attitudes about obese individuals.     

Animals,humans and x-men: Human uniqueness and the meaning of personhood

Research in animal intelligence suggests to some that humans are different only in degree from animals, possibly eroding the traditional theological doctrine of the imago dei. In this paper, several critical boundary areas between humans and animals are examined for scientific evidence about human distinctiveness. These include communication and language capacity, cultural creativity, spirituality, and ethical capacity. Chimpanzee language studies and research in Neanderthal mentality are examined as the closest known natural approximations to human communication and intelligence. The implications of the findings are explored in relation to human culture, ethics, and spirituality in a context consistent with evolutionary continuity. Aspects of human uniqueness are apparent, can be fruitfully encompassed in the idea of personhood, and are coherent with Trinitarian theology's anthropological focus.     

Televised Sexual Content and Parental Mediation: Influences on Adolescent Sexuality

Little research has been conducted to examine the influence of exposure to televised sexual content on adolescent sexuality or how parental intervention may reduce negative effects of viewing such content. This study uses self-report data from 1,012 adolescents to investigate the relations among exposure to sexually suggestive programming, parental mediation strategies, and three types of adolescent sexuality outcomes: participation in oral sex and sexual intercourse, future intentions to engage in these behaviors, and sex expectancies. As predicted, exposure to sexual content was associated with an increased likelihood of engaging in sexual behaviors, increased intentions to do so in the future, and more positive sex expectancies. Often, parental mediation strategies were a significant factor in moderating these potential media influences.     

Transfer of motor learning engages specific neural substrates during motor memory consolidation dependent on the practice structure

The authors investigated how brain activity during motor-memory consolidation contributes to transfer of learning to novel versions of a motor skill following distinct practice structures. They used 1 Hz repetitive Transcranial Magnetic Stimulation (rTMS) immediately after constant or variable practice of an arm movement skill to interfere with primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC). The effect of interference was assessed through skill performance on two transfer targets: one within and one outside the range of practiced movement parameters for the variable practice group. For the control (no rTMS) group, variable practice benefited delayed transfer performance more than constant practice. The rTMS effect on delayed transfer performance differed for the two transfer targets. For the within-range target, rTMS interference had no significant affect on the delayed transfer after either practice structure. However, for the outside-range target, rTMS interference to DLPFC but not M1 attenuated delayed transfer benefit following variable practice. Additionally, for the outside-range target, rTMS interference to M1 but not DLPFC attenuated delayed transfer following constant practice. This suggests that variable practice may promote reliance on DLPFC for memory consolidation associated with outside-range transfer of learning, whereas constant practice may promote reliance on M1 for consolidation and long-term transfer.     

2.5-year-olds use cross-situational consistency to learn verbs under referential uncertainty

Recent evidence shows that children can use cross-situational statistics to learn new object labels under referential ambiguity (e.g., Smith & Yu, 2008). Such evidence has been interpreted as support for proposals that statistical information about word-referent co-occurrence plays a powerful role in word learning. But object labels represent only a fraction of the vocabulary children acquire, and arguably represent the simplest case of word learning based on observations of world scenes. Here we extended the study of cross-situational word learning to a new segment of the vocabulary, action verbs, to permit a stronger test of the role of statistical information in word learning. In two experiments, on each trial 2.5-year-olds encountered two novel intransitive (e.g., "She's pimming!"; Experiment 1) or transitive verbs (e.g., "She's pimming her toy!"; Experiment 2) while viewing two action events. The consistency with which each verb accompanied each action provided the only source of information about the intended referent of each verb. The 2.5-year-olds used cross-situational consistency in verb learning, but also showed significant limits on their ability to do so as the sentences and scenes became slightly more complex. These findings help to define the role of cross-situational observation in word learning.
