We examined performance of healthy older and younger adults and individuals with Alzheimer's disease (AD) and Parkinson's disease (PD) on digit cancellation, a task putatively sensitive to cognitive impairment, but possibly affected by visual impairment, particularly in contrast sensitivity. Critical contrast thresholds were established to create custom stimulus arrays that were proximally matched across individuals. Age- and PD-related differences in search were fully accounted for by the sensory deficit. Increased contrast benefited AD patients, but could not override cognitive impairment. We conclude that visually fair neuropsychological testing can effectively compensate for normal age- and PD-related visual changes that affect cognitive performance.

The measurement of parenting behaviors is important to the field of psychology and the goal of remediating problematic parenting
as a means of reducing child problem behaviors. The Parenting Young Children (PARYC) is a self-report measure designed to
address parenting behaviors relevant for the caregivers of young children, and was assessed in sample of 579 high risk families.
The measure assesses the frequency of several parenting behaviors, the perception of the parenting behaviors as problematic,
and the degree to which the caregiver would like to make changes in specific parenting skills. An examination of the validity
of the parenting behavior items revealed three parenting scales: (1) Supporting Positive Behavior (2) Setting Limits, and
(3) Proactive Parenting. Confirmatory factor analysis results corroborate the findings of the exploratory factor analysis,
supporting the measurement structure of these parenting scales. Tests of convergent validity indicate the PARYC scale is a
suitable measure of parenting behaviors. In addition, the self-perception of parenting behaviors as problematic predicted
concurrent levels of service utilization while controlling for simultaneous child behavior problems. 相似文献

Motor learning-dependent synaptogenesis is localized to functionally reorganized motor cortex. 总被引:19,自引:0,他引:19

The regional specificity and functional significance of learning-dependent synaptogenesis within physiologically defined regions of the adult motor cortex are described. In comparison to rats in a motor activity control group, rats trained on a skilled reaching task exhibited an areal expansion of wrist and digit movement representations within the motor cortex. No expansion of hindlimb representations was seen. This functional reorganization was restricted to the caudal forelimb area, as no differences in the topography of movement representations were observed within the rostral forelimb area. Paralleling the physiological changes, trained animals also had significantly more synapses per neuron than controls within layer V of the caudal forelimb area. No differences in the number of synapses per neuron were found in either the rostral forelimb or hindlimb areas. This is the first demonstration of the co-occurrence of functional and structural plasticity within the same cortical regions and provides strong evidence that synapse formation may play a role in supporting learning-dependent changes in cortical function. 相似文献

Analogies help organize, communicate and reveal scientific phenomena. Vision may be the best analogy for understanding moral judgment. Although moral psychology has long noted similarities between seeing and judging, we systematically review the “morality is like vision” analogy through three elements: experience, variability and mechanism. Both vision and morality are experienced as automatic, durable and objective. However, despite feelings of objectivity, both vision and morality show substantial variability across biology, culture and situation. The paradox of objective experience and cultural subjectivity is best understood through constructionism, as both vision and morality involve the flexible combination of more basic ingredients. Specifically, both vision and morality involve a mechanism that demonstrates Gestalt, combination and coherence. The “morality is like vision” analogy not only provides intuitive organization and compelling communication for moral psychology but also speaks to debates in the field, such as intuition versus reason, pluralism versus universalism and modularity versus constructionism. 相似文献

Prevalence of hyperglycemia-related posttraumatic stress (PTS) was assessed in 239 adults with type 1 diabetes using the posttraumatic stress diagnostic scale (PDS; Foa, Posttraumatic stress diagnostic scale manual, National Computer Systems, Inc., Minneapolis, 1995) by an anonymous online survey. Additionally, this study aimed to identify variables related to hyperglycemia-related PTS. Over 30 % of participants reported symptoms consistent with PTSD related to hyperglycemia with standard PDS scoring, and 10 % with more conservative scoring. Hierarchical multiple regression analyses indicated that diabetes self-management behavior and perceived helplessness about hyperglycemia predicted PTSD with standard scoring. Perceived death threat, self-management behavior, helplessness about hyperglycemia, and severity of hypoglycemia in past month predicted PTSD using more conservative scoring. Perceived helplessness, hypoglycemia severity, perceived death-threat, HbA1c, and self-management behavior predicted PTS severity. When fear, helplessness, and perceived death-threat were combined to represent an overall cognitive appraisal factor, this variable was the strongest predictor of PTSD and PTS severity. Scores for PTSD symptom clusters appeared similar to data on hypoglycemia-related PTS. 相似文献

The Behavioral Approach System (BAS) hypersensitivity theory of bipolar disorder (BD; Alloy & Abramson, 2010; Depue & Iacono, 1989) suggests that hyperreactivity in the BAS results in the extreme fluctuations of mood characteristic of BD. In addition to risk conferred by BAS hypersensitivity, cognitive and personality variables may play a role in determining risk. We evaluated relationships among BAS sensitivity, risk taking, and an electrophysiological correlate of approach motivation, relative left-frontal electroencephalography (EEG) asymmetry. BAS sensitivity moderated the relationship between risk taking and EEG asymmetry. More specifically, individuals who were high in BAS sensitivity showed left-frontal EEG asymmetry regardless of their level of risk-taking behavior. However, among individuals who were moderate in BAS sensitivity, risk taking was positively associated with asymmetry. These findings suggest that cognitive and personality correlates of bipolar risk may evidence unique contributions to a neural measure of trait-approach motivation. Clinical implications of these findings are discussed. 相似文献

When others disagree with us, we like them more if they shift their attitude toward ours (i.e., engage in attitude alignment), but why? This article examined the effects of partner attitude alignment on dyadic (trust, inferred attraction) and personal (respect, perceived reasoning ability) evaluations. In two experiments, participants received feedback that imagined (Experiment 1) or real (Experiment 2) partners engaged (vs. did not engage) in attitude alignment; rated partners on trust, inferred attraction, respect (Experiments 1 and 2), and perceived reasoning ability (Experiment 2); and reported attraction. Individuals were more attracted to partners who engaged in attitude alignment because they viewed them as more trustworthy and worthy of respect and as possessing greater reasoning ability. The role of inferred attraction was unclear. 相似文献

There is a growing use of noncognitive assessments around the world, and recent research has posited an ideal point response process underlying such measures. A critical issue is whether the typical use of dominance approaches (e.g., average scores, factor analysis, and the Samejima's graded response model) in scoring such measures is adequate. This study examined the performance of an ideal point scoring approach (e.g., the generalized graded unfolding model) as compared to the typical dominance scoring approaches in detecting curvilinear relationships between scored trait and external variable. Simulation results showed that when data followed the ideal point model, the ideal point approach generally exhibited more power and provided more accurate estimates of curvilinear effects than the dominance approaches. No substantial difference was found between ideal point and dominance scoring approaches in terms of Type I error rate and bias across different sample sizes and scale lengths, although skewness in the distribution of trait and external variable can potentially reduce statistical power. For dominance data, the ideal point scoring approach exhibited convergence problems in most conditions and failed to perform as well as the dominance scoring approaches. Practical implications for scoring responses to Likert-type surveys to examine curvilinear effects are discussed. 相似文献

The transition to parenthood is a challenging experience that often strains relationships, but perceiving one’s partner as humble (actor relational humility) and being perceived by one’s partner as humble (partner relational humility) were hypothesized to benefit couples during this transition. Married couples (N = 69) were tracked from the third trimester of pregnancy through 21 months postpartum. Husbands and wives provided ratings of relational humility and dyadic adjustment. Actor–partner interdependence models tested actor and partner effects of relational humility on dyadic adjustment across the transition. Although couples declined in dyadic adjustment over the transition at the same rate regardless of relational humility (counter to Hypothesis 2), those higher in relational humility reported greater dyadic adjustment at each time point during the transition (consistent with Hypothesis 1). These findings support the benefits of relational humility to relationship quality, and we call for further research into humility’s benefits during times of relationship transition. 相似文献
