Implicit learning of new verbal associations

Implicit learning of a series of new verbal associations was studied in four experiments. The first two experiments demonstrated that learning of a repeating sequence of verbal stimuli may occur without awareness, but only when the stimulus-response mapping requires an attention-demanding activity: Subjects who were unaware of the sequence learned when instructed to categorize the stimuli, but not when instructed simply to read them. However, in both situations, unaware subjects performed no better than untrained control subjects in expressing their knowledge of the sequence explicitly. In Experiments 3 and 4, subjects showed implicit learning when the task involved either motor responses to verbal stimuli or verbal responses to spatially arranged stimuli. These findings are discussed in terms of the conditions under which implicit learning can be obtained. First, they demonstrate implicit learning of a set of new associations in the verbal domain. Second, the data suggest that attention is important in implicit learning. Finally, the degree of interitem organization that is familiar preexperimentally seems to partially determine the amount of implicit learning.     

Adult Age Differences in the Access and Deletion Functions of Inhibition

ABSTRACT

This study examined age differences in working memory using a delayed-matching-to-sample (DMTS) task. Based on the inhibitory decline hypothesis, which posits that older adults are more susceptible to interference, age differences were expected to be greater for older adults when irrelevant information was present during encoding. Two experiments tested both the access and deletion functions of inhibition. In both experiments, performance was equated for older and younger participants on a no-interference version of the DMTS task to control for age differences in encoding information into working memory. Results consistently showed equivalent effects of distraction for older and younger adults regardless of the difficulty of the perceptual discrimination of targets and distractors, the degree of processing of the distractors, or the semantic relationship between targets and distractors. These results support theories that propose age differences in encoding to explain age differences in working memory, and are inconsistent with theories that propose that older adults are more susceptible to interference than younger adults.     

Sex and Sociocultural Correlates of Urinary Incontinence in Israeli Preschool Children

Urinary incontinence in children aged 2 to 6 years whose mothers varied in ethnic descent, in level of education, and in immigration status was studied in Israel. Mothers of 302 children were interviewed in well-baby clinics regarding primary and secondary urinary incontinence of their children. A significant age trend was found for attaining primary urinary continence. However, various interactions between mothers' ethnic descent, mothers' level of education, and mothers' immigration status were associated with different rates of primary and secondary urinary incontinence in their children. Moreover, sex differences in rates of primary and secondary urinary incontinence were also associated with mothers' ethnic descent and level of education. It is suggested that different levels of maternal emotional availability to the child in the various subgroups can account for most of the findings.     

Incremental Validity of Situational Judgment Tests for Task and Contextual Job Performance

This paper has three goals. First, it responds to calls for additional research on subgroup differences in situational judgment tests. Second, it expands the cumulative knowledge on the incremental validity of situational judgment tests beyond cognitive ability and personality. Third, it examines the validity and incremental validity of various predictors for both task and contextual performance.     

Moral luck and the unfairness of morality

Philosophical Studies - Moral luck occurs when factors beyond an agent’s control positively affect how much praise or blame she deserves. Kinds of moral luck are differentiated by the source...
