Effects of Training Goals and Goal Orientation Traits on Multidimensional Training Outcomes and Performance Adaptability

This research examined the effects of mastery vs. performance training goals and learning and performance goal orientation traits on multidimensional outcomes of training. Training outcomes included declarative knowledge, knowledge structure coherence, training performance, and self-efficacy. We also examined the unique impact of the training outcomes on performance adaptability by predicting generalization to a more difficult and complex version of the task. The experiment involved 60 trainees learning a complex computer simulation over 2 days. The research model posited independent effects for training goals relative to goal orientation traits and independent contributions of training outcomes to the performance adaptability of trainees. The findings were consistent with the proposed model. In particular, self-efficacy and knowledge structure coherence made unique contributions to the prediction of performance adaptability after controlling for prior training performance and declarative knowledge. Implications and extensions are discussed. Copyright 2001 Academic Press.     

Applying principles of development to help at-risk preschoolers develop numeracy

In a yoked control design, multicultural Head Start 4-year-olds played numerous games involving either numeracy or the oddity principle and insertions into series. Children showed better mastery of oddity and insertions after playing games directed at those two concepts. Numeracy scores on the McCarthy Scales of Children's Abilities (D. McCarthy, 1972) were equivalent for children who played numeracy games and children who played oddity and insertion games. These results are consistent with other research indicating that the understanding of oddity relations and that of insertions are key transitional thinking abilities that support numeracy at the preschool-kindergarten interface.     

Contrasting effects of phonological priming in aphasic word production

Two fluent aphasics, IG and GL, performed a phonological priming task in which they repeated an auditory prime then named a target picture. The two patients both had selective deficits in word production: they were at or near ceiling on lexical comprehension tasks, but were significantly impaired in picture naming. IG's naming errors included both semantic and phonemic paraphasias, as well as failures to respond, whereas GL's errors were mainly phonemic and formal paraphasias. The two patients responded very differently to phonological priming: IG's naming was facilitated (both accuracy and speed) only by begin-related primes (e.g. ferry-feather), whereas GL benefited significantly only from end-related primes (e.g. brother-feather), showing no more than a facilitatory trend with begin-related primes. We interpret these results within a two-stage model of word production, in which begin-related and end-related primes are said to operate at different stages. We then discuss implications for models of normal and aphasic word production in general and particularly with respect to sequential aspects of the phonological encoding process.     

Mapping the developmental constraints on working memory span performance

This study investigated the constraints underlying developmental improvements in complex working memory span performance among 120 children of between 6 and 10 years of age. Independent measures of processing efficiency, storage capacity, rehearsal speed, and basic speed of processing were assessed to determine their contribution to age-related variance in complex span. Results showed that developmental improvements in complex span were driven by 2 age-related but separable factors: 1 associated with general speed of processing and 1 associated with storage ability. In addition, there was an age-related contribution shared between working memory, processing speed, and storage ability that was important for higher level cognition. These results pose a challenge for models of complex span performance that emphasize the importance of processing speed alone.     

Perceived stress and physiological dysregulation in older adults

We use a population-based representative sample of older Taiwanese to investigate links between respondents' perceived levels of stress and a broad set of biological measures. These biomarkers were collected at a single time (2000) and reflect sympathetic nervous system (SNS)-activity, hypothalamo-pituitary-adrenal (HPA)-activity, immune function, cardiovascular function, and metabolic pathways. We model the relationship between perceived stress and (1) extreme values for each of 16 individual biological indicators; and (2) a measure of cumulative physiological dysregulation based on the full set of biomarkers. We consider two measures of perceived stress, one derived from the 2000 interview and the second based on data from three interviews (1996-2000). Age and sex-adjusted models reveal significant associations between measures of perceived stress and extreme values of cortisol, triglycerides, interleukin-6 (IL-6), dehydroepiandrosterone sulphate (DHEAS) and fasting glucose. Examined individually, numerous biomarkers, including those pertaining to blood pressure and obesity, are not significantly related to perceived stress. Jointly, however, the measure of cumulative physiological dysregulation is associated with both the level of perceived stress at a given time and to a longitudinal measure of perceived stress. Some results suggest that the relationship between level of perceived stress and physiological response is stronger for women than men.     

A prospective study of factors that lead to body dissatisfaction during pregnancy

This study examined changes in body image and predictors of body dissatisfaction during pregnancy. It was expected that higher levels of depression, social comparison tendencies, teasing, societal pressure to be thin and public self-consciousness would predict body dissatisfaction prospectively. Healthy pregnant women (n = 128) completed questionnaires on three occasions during their pregnancies reporting on a total of four time points: 3 months prior to pregnancy (retrospectively reported), in the early to mid-second trimester, the late-second/early-third trimester, and the latter part of the third trimester. For the most part women reported adapting to the changes that occurred in their body; however, women were most likely to experience higher levels of body dissatisfaction in early to mid-second trimester. Findings related to predictors of body dissatisfaction revealed that both social and psychological factors contributed to body image changes in pregnancy. Implications of the findings are discussed.     

Counselling children and adults about AIDS/HIV: The ripple effect on haemophilia care settings

Haemophilia and HIV/AIDS are life-long, life-threatening conditions for which there is treatment but no cure. Both affect not only the patient but all members of the family. This paper focusses on how the counselling of those with AIDS/HIV has been affected by dilemmas such as treatment, infectious aspects, blood donation, sex, the media and having children. The impact of haemophilia and AIDS on the family and the ripple effect on health care staff is addressed.     

Experience-dependent neuropsychological recovery and the treatment of chronic alcoholism

This paper reviews the relationship between cognitive status and treatment outcome in chronic alcoholics, the natural history of recovery, and the role of cognitively oriented remediation programs in facilitating recovery. Seven studies of experience-dependent recovery are described in which behavioral improvement was noted. Various recommendations for treatment over the course of recovery are made, guided by anticipated changes in capacity to process complex information over time.     

A ToolBook computer program to develop course objectives and assessment measures

College courses are generally developed because of current fashion in the field and/or student and faculty interest in some topic without reference to departmental or programmatic goals. Current calls and needs for accountability in higher education demand a more organized approach. A computer program, ToolBook 1.53, which provides information to the instructor about systematic development of courses and assessment of student outcomes, is described. The program supports the construction of outcome-oriented learning objectives and corresponding assessment techniques. Instructors who used this program to learn about how to construct such objectives showed an increase in knowledge and evaluated the program positively. Using the information provided in this program leads to an integrated approach to course design and development in which course objectives are linked to the college mission statement through departmental or program objectives.
