Using words instead of jumbled characters as stimuli in keyboard training facilitates fluent performance

Keyboarding skill is an important target for adult education programs due to the ubiquity of computers in modern work environments. A previous study showed that novice typists learned key locations quickly but that fluency took a relatively long time to develop. In the present study, novice typists achieved fluent performance in nearly half the time when words rather than jumbled characters were used as stimuli. This suggests that using real words in the keyboarding program can enhance the efficiency of training.     

Task-related functional connectivity of the caudate mediates the association between trait mindfulness and implicit learning in older adults

Accumulating evidence shows a positive relationship between mindfulness and explicit cognitive functioning, i.e., that which occurs with conscious intent and awareness. However, recent evidence suggests that there may be a negative relationship between mindfulness and implicit types of learning, or those that occur without conscious awareness or intent. Here we examined the neural mechanisms underlying the recently reported negative relationship between dispositional mindfulness and implicit probabilistic sequence learning in both younger and older adults. We tested the hypothesis that the relationship is mediated by communication, or functional connectivity, of brain regions once traditionally considered to be central to dissociable learning systems: the caudate, medial temporal lobe (MTL), and prefrontal cortex (PFC). We first replicated the negative relationship between mindfulness and implicit learning in a sample of healthy older adults (60–90 years old) who completed three event-related runs of an implicit sequence learning task. Then, using a seed-based connectivity approach, we identified task-related connectivity associated with individual differences in both learning and mindfulness. The main finding was that caudate-MTL connectivity (bilaterally) was positively correlated with learning and negatively correlated with mindfulness. Further, the strength of task-related connectivity between these regions mediated the negative relationship between mindfulness and learning. This pattern of results was limited to the older adults. Thus, at least in healthy older adults, the functional communication between two interactive learning-relevant systems can account for the relationship between mindfulness and implicit probabilistic sequence learning.     

A randomized trial of employment-based reinforcement of cocaine abstinence in injection drug users

High-magnitude and long-duration abstinence reinforcement can promote drug abstinence but can be difficult to finance. Employment may be a vehicle for arranging high-magnitude and long-duration abstinence reinforcement. This study determined if employment-based abstinence reinforcement could increase cocaine abstinence in adults who inject drugs and use cocaine during methadone treatment. Participants could work 4 hr every weekday in a workplace where they could earn about $10.00 per hour in vouchers; they were required to provide routine urine samples. Participants who attended the workplace and provided cocaine-positive urine samples during the initial 4 weeks were invited to work 26 weeks and were randomly assigned to an abstinence-and-work (n = 28) or work-only (n = 28) group. Abstinence-and-work participants had to provide urine samples showing cocaine abstinence to work and maintain maximum pay. Work-only participants could work independent of their urinalysis results. Abstinence-and-work participants provided more (p = .004; OR = 5.80, 95% CI = 2.03-16.56) cocaine-negative urine samples (29%) than did work-only participants (10%). Employment-based abstinence reinforcement can increase cocaine abstinence.     

Direct and indirect measures of frequency monitoring in young and elderly adults

Memory for frequency of occurrence of novel material (Turkish words) was investigated in young and elderly adults via direct (absolute and relative frequency judgments) and indirect (reading speed) measures. Both young and elderly adults showed increased reading speed as a function of frequency of occurrence (Experiment 1). However, when asked explicitly to identify how often a word occurred (Experiment 1) or which word occurred more often (Experiment 2), elderly subjects were less accurate than young adults. These results support and extend research on age-related dissociations in memory.     

Does a simultaneous memory load affect older and younger adults’ implicit associative learning?

This study investigated the effects of a simultaneous memory load on implicit associative sequence learning using the Triplets Learning Task (TLT). Participants in the Simultaneous condition held a secondary task memory load during the TLT, while those in the Sequential condition also performed both tasks, but successively, rather than simultaneously. Thus, the Simultaneous condition had a memory load during the TLT, while the Sequential condition did not. Probe blocks without the secondary task allowed separation of effects on learning from effects on its expression. Results revealed that the simultaneous memory load affected older, but not younger adults, by suppressing the expression of learning, not learning itself. Thus, older and younger adults can learn probabilistic associations while holding a simultaneous memory load, but the load can limit the extent to which older adults adapt their performance to environmental structure. Results are consistent with theories which propose that implicit associative learning does not call on limited capacity resources, and highlight the importance of distinguishing effects of dual tasks on the expression of learning from those on learning itself.     

“The Test of a Civilization Is the Way that It Cares for Its Helpless Members”: Violence Against Older Women

Violence against women is a major health risk nationally and internationally. However, despite its impact, violence against older women remains an understudied area. Abuse of older women is frequently unrecognized unless encompassed under “elder abuse.” The purpose of this article is to (1) provide a summary of current research on violence against older women, (2) describe methodological biases in research on violence against older women, (3) discuss methodological biases that have kept the problem of violence against older women hidden from view, and (4) propose new directions for feminist research, advocacy, and therapy.     

College students' memory for vocabulary in their majors: evidence for a nonlinear relation between knowledge and memory.

The effect of domain knowledge on students' memory for vocabulary terms was investigated. Participants were 142 college students (94 education majors and 48 business majors). The measure of domain knowledge was the number of courses completed in the major. Students recalled three different lists (control, education, and business) of 20 words. Knowledge effects were estimated controlling for academic aptitude, academic achievement, and general memory ability. Domain-specific knowledge consistently predicted recall, above and beyond the effect of these control variables. Moreover, nonlinear models better represented the relation between knowledge and memory, with very similar functions predicting recall in both knowledge domains. Specifically, early in the majors more classes corresponded with increased memory performance, but a plateau period, when more classes did not result in higher recall, was evident for both majors. Longitudinal research is needed to explore at what point in learning novices' performance begins to resemble experts' performance.     

The influence of gender labels on the sex typing of imaginary occupations

Social scientists have been concerned not only with gender stratification within the occupational labor force but with young peoples' recognition and aspiration toward same-gender careers. In this paper we investigate how gender labels influence individuals' evaluational sex typing of occupations. Four gender-marked booklets were constructed such that six imaginary occupations within the story were performed by persons labeled as women, men, both men and women, or individuals. College, high-school, and fifth-and third-grade students were asked to evaluate whether a gender-marked occupation was a position for women, men, or both sexes and possible for girls and boys. Students were also asked to indicate which occupations they preferred. Not only were the occupations classified in relation to the gender labels, but occupational gender barriers were perceived. In essence, males were restricted from engaging in female-labeled jobs and females were restricted from engaging in male-labeled jobs. However, career aspirations     

Social Anxiety and Specificity of Positive Alcohol Expectancies: Preliminary Findings

This preliminary study examined the relationship between social anxiety and specificity of positive alcohol outcome expectancies (AOE) in a community sample of 62 drinking adults. The sample was divided into subsets of socially anxious (n = 17) and nonsocially anxious (n = 45) men and women. The Drinking Expectancy Questionnaire (DEQ) and Alcohol Expectancies in Social Evaluative Situations Scale (AESES) were used to determine if groups differed in the general positive AOE they hold, or only in AOE specific to social situations. ANOVAs revealed that socially anxious individuals had greater positive AOE specific to social situations (DEQ—Assertion scale and AESES) than nonsocially anxious individuals, with no differences in other positive AOE. Partial correlations controlling for social anxiety revealed that AOE specific to social situations correlated with greater drinking and alcohol dependency levels. Findings indicate that identification of AOE specific to social situations may be useful in classifying socially anxious individuals at risk for alcoholism and as a focus of expectancy challenge strategies for individuals with co-occurring social anxiety and drinking problems.
