Many pre-school children show 'Closing-in behaviour' (CIB) in graphic copying, placing their copy excessively close to, or even on top of the original. This behaviour can also be observed in patients with dementia, though it is unclear whether the superficial similarities between CIB in development and dementia reflect common underlying mechanisms. Two main(More)
The frequency and characteristics of closing-in behavior (CIB) were examined in 797 patients with Alzheimer's disease (AD), 132 of whom were followed up longitudinally. The frequency of CIB increased with the complexity of the graphic copying task and with the severity of Alzheimer's disease. Regression analyses suggested that attentional deficits are(More)
Emotional expressions are important cues that capture our attention automatically. Although a wide range of work has explored the role and influence of emotions on cognition and behavior, little is known about the way that emotions influence motor actions. Moreover, considering how critical detecting emotional facial expressions in the environment can be,(More)
This study explored Closing-in behavior (CIB), the tendency in figure copying to draw very close to or on top of the model, in mild cognitive impairment (MCI). The files of 154 people diagnosed with MCI were reviewed and CIB was identified in 21% of cases. Two approaches were used to explore CIB. First, we capitalized on the diverse cognitive profiles(More)
This study relates two behaviours, each well documented within its own literature but not previously considered together: closing-in behaviour (CIB) and the effect of visual distractors on reaching. CIB is common in typically developing children, and in adults with dementia, and classically manifests as the tendency to perform graphic copying tasks very(More)
"Closing-in behaviour" (CIB) is a phenomenon observed on copying and imitation tasks, in which the copy is made inappropriately close to or on top of the model. CIB is classified clinically as a manifestation of constructional apraxia (CA), but its underlying causes are not understood. Compensation hypotheses propose that CIB is a strategic adaptation to(More)
Normally we can perform a variety of goal-directed movements effortlessly. However, damage to the parietal cortex may dramatically reduce this ability, giving rise to optic ataxia and limb apraxia. Patients with optic ataxia show clear misreaches towards targets when presented in the peripheral visual field, whereas limb apraxia refers to the inability to(More)
Many pre-school children show closing-in behaviour (CIB) in graphic copying tasks: a tendency to place their copy abnormally close to or even on top of the model. Similar phenomena have been studied in patients with dementia, though it is unclear whether the superficial similarities between CIB in development and dementia reflect common underlying cognitive(More)
People's interaction with the social environment depends on the ability to attend social cues with human faces being a key vehicle of this information. This study explores whether directing the attention to gender or emotion of a face interferes with ongoing actions. In two experiments, participants reached for one of two possible targets by relying on one(More)
