The Rhythm Method: A New Method for Measuring Cognitive Load—An Experimental Dual‐Task Study 下载免费PDF全文
The present study joins a series of studies that used the dual‐task paradigm to measure cognitive load while learning with multimedia instruction. The goal of the current work was to develop a secondary task, to measure cognitive load in a direct and continuous way using intra‐individual, behavioral measures. The new task is achieved by utilizing internalized cues. More specifically, a previously practiced rhythm is executed continuously by foot tapping (secondary task) while learning (primary task). Precision of the executed rhythm was used as indicator for cognitive load—the higher the precision, the lower cognitive load. The suitability of this method was examined by two multimedia experiments (n1 = 30; n2 = 50). Cognitive load was manipulated by seductive details (Experiment 1: with vs. without) and modality (Experiment 2: on‐screen text vs. narration). Learners who learned under low cognitive load conditions (Experiment 1: without seductive details; Experiment 2: narration) showed significantly higher rhythm precision. These results provide evidence that rhythm precision allows for a precise and continuous measurement of cognitive load during learning. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Relations between virtues and positive mental health in a Korean population: A Multiple Indicators Multiple Causes (MIMIC) model approach 下载免费PDF全文
Young‐Jin Lim 《International journal of psychology》2015,50(4):272-278
A Multiple Indicators Multiple Causes (MIMIC) approach was applied to investigate the relationship between virtues and positive mental health as determined using the Character Strength Test and the Mental Health Continuum‐Short Form. The study participants were 876 college students (54% women; overall mean age [SD] 21.50 years [2.35]) recruited from introductory psychology courses at two universities in Seoul. Findings revealed that the intellectual virtues of college students predicted subjective well‐being according to all emotional, social and psychological measures. Results are discussed in the context of previous work using the Values in Action classification of virtues and character strengths. In addition, implications regarding understanding the nature and possible origins of positive mental health are outlined. 相似文献

Impulsive behaviour in interpersonal encounters: Associations with quarrelsomeness and agreeableness 下载免费PDF全文

Associations between impulsivity and interpersonal behaviours have rarely been examined, even though impulsivity may disrupt the flow of social interactions. For example, it is unknown to what extent the commonly used Barratt Impulsiveness Scale (BIS‐11) predicts impulsive behaviour in social situations, and how behaving impulsively during interpersonal encounters might influence levels of quarrelsomeness and agreeableness. In this study, 48 healthy working individuals completed the BIS‐11 and recorded their behaviour in social situations using event‐contingent recording. Record forms included items representing quarrelsome, agreeable, and impulsive behaviours. BIS‐11 motor impulsiveness scores predicted impulsive behaviour in social situations. Impulsive behaviour was associated, in different interactions, with both agreeableness and quarrelsomeness. Behaving impulsively in specific interactions was negatively associated with agreeableness in participants with higher BIS‐11 motor impulsiveness and positively associated with agreeableness in participants with lower BIS‐11 motor impulsiveness. Impulsive quarrelsome behaviour may cause interpersonal problems. Impulsive agreeable behaviour may have positive effects in individuals with low trait impulsivity. The idea that there are between‐person differences in the effects of state impulsivity on the flow of social interaction deserves further study. 相似文献

This study aimed to explore health professionals' views and practice regarding the provision of information about health-protective behaviors (e.g., exercise, alcohol consumption, diet) during genetic consultation for breast cancer. Ten genetic counselors participated in three focus groups, and seven medical specialists were interviewed in a focus group or individually. Data was analyzed using the constant comparative method. Findings suggested that health professionals held differing, often opposing, views about the value of health-protective behaviors for women at increased risk of breast cancer. The content and extent of information provided about health-protective behaviors varied widely, and participants expressed a need to form consensus regarding information provision both within and across clinics. The main barriers to providing information regarding health-protective behaviors included the lack of research evidence regarding the impact of these factors and higher priority of other information need to be provided in the limited consultation time. Participants generally did not consider it their role to promote health-protective behaviors, and were concerned about the psychological impact of providing information about behavioral risk factors during genetic consultations. 相似文献

The majority of computationally specified models of recognition memory have been based on a single-process interpretation,
claiming that familiarity is the only influence on recognition. There is increasing evidence that recognition is, in fact,
based on two processes: recollection and familiarity. This article reviews the current state of the evidence for dual-process
models, including the usefulness of the remember/know paradigm, and interprets the relevant results in terms of the source
of activation confusion (SAC) model of memory. We argue that the evidence from each of the areas we discuss, when combined,
presents a strong case that inclusion of a recollection process is necessary. Given this conclusion, we also argue that the
dual-process claim that the recollection process is always available is, in fact, more parsimonious than the single-process
claim that the recollection process is used only in certain paradigms. The value of a well-specified process model such as
the SAC model is discussed with regard to other types of dual-process models. 相似文献

There is resurgent interest in the psychiatric literature in endophenotypes, variables thought to more strongly reflect the
effects of candidate genes than do manifest disorders. In a sample of 176 children with attention deficit hyperactivity disorder
(ADHD) and 52 of their siblings, we examined the validity of several putative endophenotypes for ADHD that represent commonly
used clinical measures of multiple cognitive/neuropsychological domains of executive functions (EFs). We review their distributional
normality, their relations to ADHD symptoms in probands and unaffected siblings relative to nonADHD controls, and their correlation
in siblings. We also tested the EF measures’ associations with the ADRA2A gene and whether they mediated or moderated the associations between ADHD and ADRA2A. Several EF measures showed association with ADRA2A, as well as moderation, but not mediation, of its association with ADHD. Implications of the results for evaluating the validity
and utility of putative endophenotype measures and for finding candidate gene effects on ADHD are discussed. 相似文献

Behavioral research suggests that Westerners focus more on objects, whereas East Asians attend more to relationships and contexts.
We evaluated the neural basis for these cultural differences in an event-related fMRI study. East Asian and American participants
incidentally encoded pictures of (1) a target object alone, (2) a background scene with no discernable target object, and
(3) a distinct target object against a meaningful background. Americans, relative to East Asians, activated more regions implicated
in object processing, including bilateral middle temporal gyrus, left superior parietal/angular gyrus, and right superior
temporal/supramarginal gyrus. In contrast to the cultural differences in object-processing areas, few differences emerged
in background-processing regions. These results suggest that cultural experiences subtly direct neural activity, particularly
for focal objects, at an early stage of scene encoding. 相似文献

A simple instance of coupling behavior to the environment is oscillating the hands in pace with metronome beats. This environmental coupling can be weaker (1 beat per cycle) or stronger (2 beats per cycle). The authors examined whether strength of environmental coupling enhanced the stability of in-phase bimanual coordination. Detuning by manipulanda that produced different left and right eigenfrequencies shifted the relative phase angle from 0 degrees, with the size of the shift larger for higher movement frequencies. Stronger environmental coupling was found to decrease this relative-phase shift, with accompanying increase and reduction, respectively, in recurrence quantification measures related to coordination stability and coordination noise. Stronger environmental coupling also increased oscillation amplitude. Results are considered from the perspective of parametric stabilization. 相似文献
