Where There is Smoke There is Fear-Impaired Contextual Inhibition of Conditioned Fear in Smokers
2016
The odds-ratio of smoking is elevated in populations with neuropsychiatric diseases, in particular in the highly prevalent diagnoses of post-traumatic stress and anxiety disorders. Yet, the association between smoking and a key dimensional phenotype of these disorders—maladaptive deficits in fear learning and fear inhibition—is unclear. We therefore investigated acquisition and memory of fear and fear inhibition in healthy smoking and non-smoking participants (N=349, 22% smokers). We employed a well validated paradigm of context-dependent fear and safety learning (day 1) including a memory retrieval on day 2. During fear learning, a geometrical shape was associated with an aversive electric…
The development of facial emotion recognition: The role of configural information
2007
International audience; The development of children's ability to recognize facial emotions and the role of configural information in this development were investigated. In the study, 100 5-, 7-, 9-, and 11-year-olds and 26 adults needed to recognize the emotion displayed by upright and upside-down faces. The same participants needed to recognize the emotion displayed by the top half of an upright or upside-down face that was or was not aligned with a bottom half that displayed another emotion. The results showed that the ability to recognize facial emotion develops with age, with a developmental course that depends on the emotion to be recognized. Moreover, children at all ages and adults e…
‘Ain't nothin' like the real thing’. Motivation and study processes on a work-based project course in information systems design
2007
Background. Advocates of the project method claim that project-based learning inspires student learning. However, it has been claimed that project-based learning environments demand quite a bit of self-regulation on the part of the learner. Aims. Consequently, it was tested whether students scoring low in self-regulation of learning experienced ‘friction’, an incompatibility between student self-regulation and the demands posed by the learning environment. This would be manifest in cognitive processing and motivation. Samples. The target group consisted of 58 mainly third-year Finnish university students taking a mandatory project course in information systems design. During the project cou…
Is the go/no-go lexical decision task an alternative to the yes/no lexical decision task?
2002
In the go/no-go lexical decision task (LDT), participants are instructed to respond as quickly as they can when a word is presented and not to respond if a nonword is presented. By minimizing part of the response selection process in the experimental task, the impact of response decision time on the obtained lexical decision time is probably reduced relative to the standard yes/no LDT (Gordon, 1983). Experiments 1 and 2 show that the go/no-go LDT is sensitive to the effects of word frequency and associative priming--the magnitude of these effects is similar with the two tasks. More important, the go/no-go LDT has a number of advantages with respect to the "standard" yes/no LDT: It offers fa…
Standardization and validation of a parallel form of the verbal and non-verbal recognition memory test in an Italian population sample.
2017
In the neuropsychological assessment of several neurological conditions, recognition memory evaluation is requested. Recognition seems to be more appropriate than recall to study verbal and nonverbal memory, because interferences of psychological and emotional disorders are less relevant in the recognition than they are in recall memory paradigms. In many neurological disorders, longitudinal repeated assessments are needed to monitor the effectiveness of rehabilitation programs or pharmacological treatments on the recovery of memory. In order to contain the practice effect in repeated neuropsychological evaluations, it is necessary the use of parallel forms of the tests. Having two parallel…
Prenatal exposure to organochlorine compounds and neuropsychological development up to two years of life
2012
Polychlorinated biphenyls (PCB), hexachlorobenzene (HCB), and dichlorodiphenyl dichloroethylene (pp′DDE) are persistent, bioaccumulative, and toxic environmental pollutants with potential neurotoxic effects. Despite a growing body of studies investigating the health effects associated with these compounds, their specific effects on early neuropsychological development remain unclear. We investigated such neuropsychological effects in a population-based birth cohort based in three regions in Spain (Sabadell, Gipuzkoa, and Valencia) derived from the INMA [Environment and Childhood] Project. The main analyses in this report were based on 1391 mother–child pairs with complete information on mat…
Arrival-time judgments on multiple-lane streets: the failure to ignore irrelevant traffic
2014
How do road users decide whether or not they have enough time to cross a multiple-lane street with multiple approaching vehicles? Temporal judgments have been investigated for single cars approaching an intersection; however, close to nothing is known about how street crossing decisions are being made when several vehicles are simultaneously approaching in two adjacent lanes. This task is relatively common in urban environments. We report two simulator experiments in which drivers had to judge whether it would be safe to initiate street crossing in such cases. Matching traffic gaps (i.e., the temporal separation between two consecutive vehicles) were presented either with cars approaching o…
Rifle-balancing in precision shooting:behavioral aspects and psychophysiological implication
2007
This study investigated sharpshooters' strategies to control their rifle stability during the aiming period. Six elite and six pre-elite shooters completed a simulated realistic shooting task (laser rifle), and their performance was evaluated from behavioral and psychophysiological perspectives. The analysis of the rifle's barrel movement, indexing the shooter's behavioral performance, supported the view that rifle-balancing is an essential determinant of superior shooting performance. The psychophysiological data, i.e. the brain slow potentials, suggested that the shooters applied different rifle-hold strategies; the elite shooters concentrated primarily on achieving a stable rifle positio…
Attitude and knowledge of pain management among Italian nurses in hospital settings
2015
Pain is multidimensional, and, as such, the chief reason patients seek urgent healthcare services. If inadequately assessed and untreated, pain may negatively impact on the quality of life of the patient. Treating pain is an important step in regaining control over quality of life. The objective of the present study is to examine the level of knowledge and types of approach among Italian nurses who deal with pain assessment and management. The Ferrell and McCaffery's Knowledge and Attitudes Survey Regarding Pain (KASRP) was distributed to 286 nurses employed in one of the biggest specialized hospitals in Rome, Italy. The interviewed staff work at three different settings, according to the h…
Facilitating holistic continuity of care for older patients: Home care nurses' experiences using checklists.
2019
Aims and objectives To explore home care nurses' experiences of implementation and use of checklists developed for improving continuity of care for older patients (65+ years). Background The Norwegian Coordination Reform was implemented to improve coordination between hospitals and communities and facilitate a quicker return to home community after hospital discharge. To follow-up, national learning networks were initialised to improve pathways for chronically ill older patients, including the development and use of standardised checklists. Design An explorative qualitative design was chosen. Methods Three focus group interviews were conducted, including 18 registered nurses from eight muni…
