Effects of test anxiety on motor learning: The processing efficiency hypothesis

Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.     

The control of training and transfer effects in the Minnesota Spatial Relations and other tasks

An experiment was carried out to demonstrate transfer of training in preschool children on tasks where transfer had previously been demonstrated in different populations. No evidence for transfer was found in any of the three tasks employed. The possibility that this finding was due to the lack of appropriate controls for the effects of specific training was examined using three groups to provide base-lines for the effects of practice, cognitive stimulation and social intervention. No significant differences were found either at post-test or follow-up between the specific training group and the control groups. A second experiment controlled for the effects of pre-testing. It was found that considerable transfer occurred from the pre-test trial to the first training trial. It appeared that one trial was sufficient to allow subjects to develop a strategy which was appropriate for both the training and transfer materials. Experiments of this type can clearly indicate whether or not some basic processes can be modified by means of short-term intervention and have implications for inducing longer-term benefits.     

Predicting early emotion knowledge development among children of colour living in historically disinvested neighbourhoods: consideration of child pre-academic abilities,self-regulation,peer relations and parental education

ABSTRACT

Emotion knowledge, the ability to accurately perceive and label emotions, predicts higher quality peer relations, higher social competence, higher academic achievement, and fewer behaviour problems. Less is known, however, about predictors of early development of emotion knowledge. This study examines emotion knowledge development among children attending pre-Kindergarten and Kindergarten programmes in high-poverty urban schools. The study considers child pre-academic abilities, self-regulation, peer relations and parental education as predictors of emotion knowledge development over two years. The sample (n?=?1034) of children living in historically disinvested neighbourhoods was primarily Black (85%) and low-income (～61%). The sample was part of a longitudinal follow-up study of a cluster (school) randomised controlled trial in ten public elementary schools. Children’s emotion knowledge was assessed with a series of tasks three times over a two-year period. At baseline, parents and teachers reported on peer relations, children completed a test of pre-academic abilities, independent observers rated child self-regulation, and parents reported on their educational attainment. Results demonstrate that emotion knowledge increases over time, and pre-academic abilities, self-regulation, peer relations, and parent education independently predict children’s emotion knowledge. This study highlights multiple factors that predict emotion knowledge among primarily Black children living in historically disinvested neighbourhoods.     

Greater Intermanual Transfer in the Elderly Suggests Age-Related Bilateral Motor Cortex Activation Is Compensatory

ABSTRACT. Hemispheric lateralization of movement control diminishes with age; whether this is compensatory or maladaptive is debated. The authors hypothesized that if compensatory, bilateral activation would lead to greater intermanual transfer in older subjects learning tasks that activate the cortex unilaterally in young adults. They studied 10 young and 14 older subjects, learning a unimanual visuomotor task comprising a feedforward phase, where there is unilateral cortical activation in young adults, and a feedback phase, which activates the cortex bilaterally in both age groups. Increased intermanual transfer was demonstrated in older subjects during feedforward learning, with no difference between groups during feedback learning. This finding is consistent with bilateral cortical activation being compensatory to maintain performance despite declining computational efficiency in neural networks.     

A test for order relevance in a three-element serial learning task

Rats were trained in a straight runway on a simple three-element series of differing reward quantities. The first trial of the series ended with a two-pellet reward, and the second and third trials ended with a 12-pellet reward and a nonreward, respectively (2-12-0). All animals developed accurate anticipation of the terminal nonreward in the 2-12-0 series before it was rearranged for two test days during which the elements appeared in the order 12-2-0. The rats' anticipation of the terminal nonreward did not transfer to the reordered series, a result taken to mean that anticipation had been based upon interitem associations among memorial representations of the differing reward quantities. A second transfer test to 0-0-0, given after anticipation was reestablished to the 2-12-0 series, gave evidence that the ordinal position of the series elements was also a source of anticipation; the animals continued to run relatively slowly on the third trial in extinction. In neither transfer test was there evidence that the rats employed the strategy of enumerating rewarded trials, because counting is an order-irrelevant process.     

Language functioning after bilateral prefrontal leukotomy

Three groups of patients with orbital frontal lesions secondary to leukotomy were compared to psychiatric and normal control groups on a series of tasks involving language. The results indicated that chronic orbital frontal lesions, at least in the patients in this study, do not affect language as defined by the tasks used in the study. The frontal lobes, when implicated in language, appear to require dorsal-lateral or medial cortical involvement.     

Influence of Expertise on the Intentional Transfer of Motor Skill

Intentional transfer of expert knowledge is an important issue in cognitive science and motor skills. How subjects deliberately transfer expertise in karate when learning a closely related motor skill (tai chi) was examined in this study. Subjects (N = 20) learned a videotaped sequence of self-defense movements, evaluated their learning, and then performed the sequence. Self-regulation of learning is believed to be central to effective transfer. The measures of self-regulation were accuracy of self-evaluation, video use, and approach to learning. Results showed that unlike novices, experts used self-regulation, learning strategies, and the video player in more complex ways in self-regulation. Experts, as compared with novices, demonstrated their greater knowledge through the higher quality of their performance and their better comprehension of movement meaning; but both groups recalled an equal number of moments, suggesting that both experts and novices transferred general knowledge about learning.     

Two functional magnetic resonance imaging f(MRI) tasks that may replace the gold standard, Wada testing, for language lateralization while giving additional localization information

Two tasks were used to lateralize and localize language functions noninvasively, using functional magnetic resonance (fMRI BOLD sequences). fMRI images produced during comprehension of the gist of a tale derived from an ordered series of inferential questions were used to lateralize and locate the center of and margins within language dominant hemisphere near posterior temporal-parietal-occipital (TPO) cortical area(s), e.g., Wernicke's. A silent noun-generating task was used to lateralize and localize naming functions within and along superior temporal gyrus (STG) and/or the basal temporal language area (BTLA) in fusiform gyrus. Used within a series of tasks, their purpose was to investigate the reliability and validity of replacing the invasive gold standard for language lateralization, Wada test, with a noninvasive test, BOLD fMRI.     

Socially Shared Regulation in Collaborative Groups: An Analysis of the Interplay Between Quality of Social Regulation and Group Processes

This study extends prior research on both individual self-regulation and socially shared regulation during group learning to examine the range and quality of the cognitive and behavioral social regulatory sub-processes employed by six small collaborative groups of upper-elementary students (n = 24). Qualitative analyses were conducted based on videotaped observations of groups across a series of three mathematics tasks. Variation in the quality of social regulation as a function of group processes (positive and negative socioemotional interactions, collaborative and non-collaborative interactions) was also considered. Findings suggested that the synergy among the social regulatory processes of planning, monitoring, and behavioral engagement was important for differentiating quality variation between groups. Positive socioemotional interactions and collaboration also appeared to facilitate higher quality social regulation. Implications for comprehensively supporting high quality social regulation, alongside positive socioemotional interactions and collaboration, in small group contexts are discussed.     

Analyzing the latent factor structure of self-regulation in preschoolers: New directions regarding a differentiation of cool self-regulation

ABSTRACT

Self-regulation in preschool-aged children is a much-researched topic, but there are still disagreements regarding the dimensionality of the construct. Most studies distinguish between hot and cool self-regulation and consider self-regulation as two-factorial. Hot self-regulation tasks refer to the ability to adapt appropriately to emotional stimuli, while cool self-regulation tasks are emotionally neutral. Our study contributes to the understanding of self-regulation at preschool age and reveals new insights concerning a more differentiated view of cool self-regulation. With a total sample of 434 preschool-aged children, we conducted confirmatory and exploratory factor analyses that demonstrated a three-factorial solution. In accordance with the variables that determined the factor structure, we inferred one hot and two cool self-regulation dimensions. We identified a time component in task scoring as a potential reason for the differentiation in cool self-regulation. The novelty of our findings and study limitations are considered.     

Unstable in more ways than one: reaction time variability and the neuroticism/distress relationship

The authors hypothesized that a greater degree of stimulus-response variability could either serve adaptive or maladaptive control purposes, depending on levels of Neuroticism. Specifically, a more variable relation between stimulus and response may be emotionally beneficial if such flexibility is used to support non-neurotic forms of self-regulation, but costly if it is used to support neurotic forms of self-regulation. To investigate these ideas, the authors asked 232 college undergraduates within three studies to perform several choice reaction time (RT) tasks. On the basis of performance, we could quantify stimulus-response variability in terms of RT variability from trial to trial. Such a measure of stimulus-response variability interacted with Neuroticism in predicting momentary negative affect (Study 1), informant judgments of negative affect (Study 2), and informant judgments of anxious symptoms (Study 3). As hypothesized, greater stimulus-response variability tended to be associated with less distress among individuals low in Neuroticism, but more distress among individuals high in Neuroticism. The results highlight the manner in which Neuroticism may "taint" control functions, in turn reinforcing Neuroticism-linked outcomes.     

Supporting the self-regulatory resource: does conscious self-regulation incidentally prime nonconscious support processes?

Ego-depletion (depletion of self-regulatory strength) can impair conscious efforts at self-regulation. Research into nonconscious self-regulation has demonstrated that preconscious automaticity and implementation intentions can automatically carry out regulatory tasks during times of ego-depletion. However, preconscious automaticity can only emerge during well-practiced tasks while implementation intentions can only support tasks that have been explicitly planned. Thus, when it comes to supporting the conscious self-regulation of nonroutine and unplanned behaviour during times of ego-depletion these processes should be ineffective. However, it is argued here that because the conscious self-regulation of nonroutine and unplanned behaviour can incidentally prime the underlying mental representations those primed representations can be postconsciously re-activated to support that behaviour during times of ego-depletion. Postconscious self-regulation might, therefore, support a type of self-regulatory behaviour that has, thus far, not been associated with any form of support.     

Improving FASD Children’s Self-Regulation: Piloting Phase 1 of the GoFAR Intervention

ABSTRACT

The initial parent training component of GoFAR, an intervention designed to improve the self-regulation and adaptive living skills of children with Fetal Alcohol Spectrum Disorders (FASDs), was piloted in a small, randomized clinical trial of 28 participants assigned to either a time-lapsed control group or one of two parent training groups who differed on whether the child’s computerized instruction was congruent or incongruent with the parent instruction. Parental compliance and achievement of therapy goals were indicators of improvement in the child’s self-regulation skills. Children who received computerized instruction consistent with the parent training demonstrated greater self-regulation improvements than those receiving incongruent computerized instruction.     

One trial learning and the suppression of interference

An experiment was made to investigate the conditions under which a subject who has learned a series of items in one order can relearn the same items in a different order in one trial. The hypothesis tested was that one-trial learning is ensured in this situation if interference between the two tasks is reduced to zero. It is shown that complete suppression of such interference, obtained by overtraining on the task which is learned first, is not sufficient to ensure the learning of the second in one trial. Comparison of the present experiment with a similar one reported by Mandler and Heinemann (1956) suggests the hypothesis that the discovery of order in the stimulus situation is necessary, in addition to the suppression of interference, if one trial learning is to occur. The relation of the results to the problem of negative transfer is also discussed.     

右侧脑发育不全患者启动效应与智力水平分离

采用 ＷＭＳ－ＣＲ． ＷＩＳＣ－ＣＲ和４项内隐记忆任务（偏好、自由联想、字根补笔和字辨认）观察一例右侧脑发育不全患者和两正常对照组被试的智商、记忆商和启动效应。发现该患者智力发育迟滞、记忆功能严重损伤,但启动效应正常。提示右侧脑发育不全患者启动效应与智力测验结果分离。由于启动效应是人类的一种重要的无意识习得能力,因此该研究表明智力发育迟滞者或脑损伤患者仍可能存在较好的无意识习得能力,这对特殊教育和临床脑损伤患者康复有一定的参考价值;同时该研究提示当前智力测验未能反映大脑功能的无意识方面,提出今后的智力测验应包括无意识习得能力的测量。     

Transfer of training and skill assumptions in tracking tasks

Matched groups of subjects were used to test the learning and transfer effects that follow changes in the display, the muscular reactions and the directional relationship between stimulus and response in a tracking task. Two arrangements were compared in the relationship studies: one arrangement of the stimuli and reactions was similar, and the other was opposed to that used in many every-day skills. The familiar arrangement was easier to learn. There was high positive transfer from the unfamiliar to the familiar, and little transfer from the familiar to the unfamiliar.

The physical dimensions of the display were varied to give two tasks with different stimuli. The initial learning times were equal for both tasks, and the transfer between them was high, positive, and equal. Two further tasks varied in the extent, speed and force of the required muscular movements. One task proved more difficult to learn initially, and there was greater transfer from the difficult to the easy task than from the easy to the difficult. A further experiment tested the effects of changing the difficulty of a tracking course, and it was found that learning was more rapid on the more difficult course. A difference in difficulty between two tasks, therefore, determined both the amount of transfer between them and the rate of learning the tasks.

New measures were developed to test the transfer between tasks of unequal content, and the effect of such inequalities upon the rate of learning. The findings are discussed, as are their possible implications for transfer measurement and their bearing upon existing theories of transfer.     

ANALYSIS OF WORK GROUP PRODUCTIVITY IN AN APPLIED SETTING: APPLICATION OF A TIME SERIES PANEL DESIGN

We provide a demonstration of a time series panel analysis applied under typical field research conditions characterized by (a) a small number of groups (b) all of which experience an intervention (thus there is no traditional control group), and (c) perform noncomparable tasks. The time series techniques allow a direct test of Naylor, Pritchard, and Ilgen's (1980) theory of behavior in organizations applied to work group productivity in a large-scale study of work groups conducted by Pritchard and colleagues (1989). The responses of 5 work groups to priority scores for 37 indicators of productivity over 23 months were used to predict month-by-month changes in productivity for each of the 37 group products. The results show that group productivity improvements can be explained by feedback including priority scores derived from nonlinear contingency functions of the productivity indicators. Furthermore, groups differed in their response to priority feedback. Goal setting positively affected productivity gain consistently across work groups, after the effects of priority feedback and the interaction of work groups with priority feedback were accounted for. Implications for group performance strategies and appropriate applications of the time series panel analysis are discussed.     

Self-recognition and self-regulation: the relationship with socialization trajectories and children's sex

The initial process of self development involves interaction with others and the establishment of relationships taking different paths depending on the socio-cultural context. Self-recognition and self-regulation are considered manifestations of this development between 18 and 24 months of age. This study aimed at analyzing the relationship between these two aspects, maternal beliefs about autonomy and relatedness, as well as identifying differences between boys and girls in this developmental stage. Participants were 94 mothers of different educational levels and their children of 17-22 months of age in two Brazilian cities. Socialization Goals Inventory and Parental Practices in the First Year Inventory were used to collect data on mothers' beliefs. Children performed tasks related to self-recognition (the mirror test) and self-regulation (compliance to requests). The group of mothers studied valued both autonomy and interdependence. Children's responses are consistent with a perspective of relational autonomy, which value both independence and interdependence. Differences were found in relation to sex in both self-recognition and self-regulation, and baby girls showed superior performance than boys in both tasks.     

The moderating role of internalising negative emotionality in the relation of self-regulation to social adjustment in Italian preschool-aged children

The purpose of this study was to examine the moderating role of internalising negative emotionality (i.e., anxious, concerned, and embarrassed displays) in the association between children's self-regulation and social adjustment. Seventy-four Italian children (44 girls, 30 boys; M age?=?35.05 months, SD?=?3.57) were assessed using two self-regulation tasks. Internalising negative emotionality was assessed through observations of children's emotion expressions during the tasks. Teachers evaluated children's social competence and internalising and externalising problems. Results demonstrated that among children who exhibited internalising negative emotionality, self-regulation was positively associated with social competence and negatively related to externalising problems. Our results suggest that self-regulation may play a crucial role for social adjustment when children show emotions such as anxiety and embarrassment during challenging situations.     

Exploration and avoidance in rats with lesions in amygdala and piriform cortex

Lesions localized to specific areas of the amygdala and overlying cortex in rats produced differential effects in several behavioral tasks. Three different types of lesions were tested: central, basolateral, and cortex lateral to the amygdala. Lesions restricted to the central nucleus produced increased activity on all parameters studied in an open-field test, but the other two groups were not changed. In one-way active avoidance all three groups with lesions showed deficits. The most pronounced change was observed in the central group. All groups showed the same degree of retention loss, but in forced extinction of one-way active avoidance after retraining, the cortical and basolateral groups were most defective. A fear-reduction hypothesis is proposed for the central lesion. The basolateral and cortical areas may be more specifically involved in passive avoidance behavior.
