Characterizing the Nature and Structure of Child Temperament via Observational Laboratory Tasks
… children who completed a battery of standardized laboratory tasks designed to elicit individual differences in emotionality and behaviour. Confirmatory factor analysis supported a five-factor structure of children’s temperament: sociability, positive affectivity/interest, impulsivity versus …

Cardiovascular Activity During Laboratory Tasks in Individuals with High and Low Worry
… reactivity and delayed recovery to laboratory stressors, and to increased risk of cardiovascular disease. This study examined cardiovascular responses in high and low worriers to a range of laboratory tasks. The aim of this study was to determine if there is a task-specific …

Transfer of heart rate feedback training to reduce heart rate response to laboratory tasks
… to reduce HR responses to the three training tasks with no HR feedback was assessed during an immediate post-training period, which followed training on each task. The participants' ability to reduce HR responses to the training tasks and a speech task was assessed during short delay (i.e., …

Cardiovascular Reactivity to and Recovery from Laboratory Tasks in Low and High Worry Women
… reactivity and delayed recovery to laboratory stressors, and to increased risk of cardiovascular disease. Previous research on the anxiety-cardiovascular system relationship, including data from Knepp and Friedman (2008), are included to support this project. Two experiments were …

The Role of Executive and Motivational Laboratory Tasks in the Assessment of Externalizing and Internalizing Problems in ADHD-C and Non-ADHD-C Youth
The current study utilized laboratory tasks (Conners' Continuous Performance Test, CPT; Behavioral Inhibition Task, BIT) to examine the relationships among motivation, executive functioning, and parent and teacher-reported attention, internalizing, and externalizing problems in a clinical sample of …

The ecological validity of prospective memory experimentation
… Discrepancies between performance in standard laboratory tasks versus naturalistic tasks has led to translational concerns to everyday life. Validity concerns surrounding laboratory PM tasks have been raised due to the lack of relationship between PM performance and measures of strategic …

The Role of Caregiver Contingent Responsiveness In Promoting Compliance and Preventing Verbal and Physical Aggression In Preschool-Aged Children
… with their 3-6 year-old children during two laboratory tasks. Parent responses to child bids were classified into four mutually exclusive categories: contingent responses, non-contingent non-negative responses, negative responses, and no response. Hierarchical regression analyses were used to …

Anger and denial as predictors of cardiovascular reactivity in women
… have suggest that women are less reactive to laboratory tasks than men. For the present study, 45 undergraduate women, ages 19-21 were selected from a larger sample of 135 women to represent three discrete groups: (1) low anger/low denial, (2) high anger/low denial, and (3) low anger/high …

Strategies adopted by undergraduate physics students when modelling solutions to hands-on tasks
… been a move away from the use of recipe-style tasks in physics laboratories to inquiry-based problem solving. From the ensuing research, model-based views of physics have emerged which have contributed to the fields of pedagogy as well as epistemology; the contribution depending on whether the …

Laboratory-based tasks in the diagnosis of ADHD in adults: a theoretical and empirical analysis
… utility of the Conners CPT and the P ASAT as a laboratory-based measures of attention, vigilance, working memory, and sustained mental effort in clinic-referred adults with and without ADHD. Moreover, the study was conducted in order to obtain additional evidence in ongoing efforts to clarify …

Cognitive Neurostimulation: Learning to Volitionally Invigorate Mesolimbic Reward Network Activation
… or delivering behavioral incentives in laboratory tasks. A critical open question concerns whether individuals can modulate activation within this system volitionally. That is, can individuals use self-generated thoughts and imagery to invigorate this system on their own? This process …

Attentional and affective mechanisms in worry and rumination
… we examined the utility of new tools (i.e., laboratory tasks, ecological momentary assessment) developed to assess the initiation and termination phases of worry and rumination. Lastly, we investigated which attentional and executive processes, if any, are involved in the initiation and …

Decision-making in autism spectrum conditions
… The behaviour of the ASC group on some of the laboratory tasks of decision-making were consistent with the experiences they reported. Conclusions: The findings suggest that decision-making can be particularly difficult for adults with ASCs and some possible reasons for these difficulties are …

Questioning for appropriate assessment and learning
… formative assessment introduced into a practical laboratory session through the use of pre and post laboratory tasks for first year undergraduate chemistry students. In this study a VLE was used to host a series of pre laboratory quizzes and post laboratory activities which aimed to help encourage …

Experimentally-induced success and failure in bulimic and nonbulimic women: cognitive and affective responses
… condition, in which their ”performance” on laboratory tasks was predetermined by very easy or impossible tasks, respectively. Standardized feedback statements, positive or critical, were issued during the experiments. Before, in the middle of, and after the experiment, subjects completed …

Psychological, cardiovascular and haematological aspects of the type A behaviour pattern in relation to coronary heart disease
… Scales) have been shown to perceive performance tasks as more threatening than Type B's. not only by their enhanced cardiovascular reactivity (heart rate and systolic blood pressure), but also by their superior word recall performance. Dyadic interactive situations, in which combinations of Type …

The Impact of Anterior Cruciate Ligament Reconstruction, Sex, and Sport-specific, Game-like Factors on Limb Stiffness and Limb Stiffness Asymmetry during Landing
… Moreover, game-like, sport-specific landing tasks with a greater horizontal component that load the ACL and those that divert attention away from landing strategies may uncover differences that do not appear in standard, controlled laboratory tasks. The overall goal of this project was to use …

Choking under pressure : attention and motor control in performance situations
… movement sequence. Performance in two different laboratory tasks was assessed with respect to overt performance (the observable result, for example accuracy in the target), covert performance (description of movement execution, for example the acceleration of body segements) and task exploitation …
