Links with science have been argued to improve the (innovation) performance of firms. Yet we still know comparatively little about the project-level characteristics affecting the organization of such links. Our study, based on a sample of 52 projects carried out by a multinational company in the semiconductor industry, reveals that the knowledge attributes of a project help in predicting how the R&D activities will be organized. In particular, basic projects are likely to be developed through formal cooperative agreements with universities. Such projects also tend to be strategically less important. For strategically more important projects, in contrast, and for those where the knowledge to be developed is particularly novel to the firm, the firm is more likely to resort to formal contracting with a university for a specific component of the R&D project, usually early on in the project. 相似文献

Holistic face processing was investigated in newborns, 3-month-old infants, and adults through a modified version of the composite face paradigm and the recording of eye movements. After familiarization to the top portion of a face, participants (N = 70) were shown 2 aligned or misaligned faces, 1 of which comprised the familiar top part. In the aligned condition, no visual preference was found at any group age. In the misaligned condition, 3-month-olds preferred the face stimulus with the familiar top part, adults preferred the face stimulus with the novel one, and newborns did not manifest any visual preference. Results revealed that both infants' and adults' eye movements may be affected by holistic face information and demonstrated holistic face processing in 3-month-olds. 相似文献

We report a two-year longitudinal study aimed at investigating the rate of access to numerical and non-numerical information in long-term memory and the functioning of automatic and effortful cognitive inhibition processes in children with arithmetical learning disabilities (ALDs). Twelve children with ALDs, of age 9.3 years, and twelve gender–age-matched controls were involved in the study. Rate of access was measured through digit- and letter-naming tasks, automatic cognitive inhibition was measured using a negative priming paradigm, and effortful cognitive inhibition was measured rating intrusion errors in a working memory task. Children with ALDs suffered from a deficit in the speed of activating both numerical and non-numerical information from long-term memory and in effortful inhibition mechanisms. No evidence for dysfunction of the automatic inhibition processes was found. 相似文献

The study uses an orthographic judgment task to evaluate the efficiency of the lexical reading route in Italian dyslexic children.
It has been suggested that Italian dyslexic children rely prevalently on the sub-word-level routine for reading. However,
it is not easy to test the lexical reading route in Italian directly because of the lack of critical items (irregular words),
so visual lexical decision tasks and the comprehension/detection of pseudo-homophones are often used. While the former may
also be solved on the basis of visual familiarity or phonological re-codification, the latter also involves conceptual and
syntactic skills. Eleven dyslexic children participated in the study, performing an orthographic judgment task on stimuli
with two phonologically plausible spellings, of which only one was orthographically correct. Their performance was compared
with those of 11 proficient readers. The dyslexic children showed selective impairment in detecting phonologically plausible
errors, but their performance was normal when required to judge errors inserted in words with regular orthography, i.e., devoid
of orthographic ambiguity, and for which a sub-word-level reading procedure is sufficient to guarantee a good performance.
Overall, data are coherent with a diagnosis of surface dyslexia, with most children showing defective orthographic lexical
processing.

Five experiments examined 79 newborns’ ability to discriminate and categorize a spatial relation, defined by the left–right spatial position of a blinking object‐target with respect to a vertical landmark‐bar. Three‐day‐old infants discriminated the up versus low position of an object located on the same side of the landmark‐bar (Experiment 1) and recognized a basic left–right spatial invariance of the object‐target and the landmark‐bar in conditions of low (Experiment 2) and high (Experiment 3) perceptual variability of the object’s positions. Additional evidence ruled out the possibility that newborns were unable to discriminate the within‐category left–right spatial positions of the object‐target (Experiment 4) or made a categorical distinction based on spatial distance rather than on categorical spatial relations of left of and right of (Experiment 5). 相似文献

A longitudinal study analyzed (a) which lower- and higher-level semantic components uniquely predicted listening text comprehension and (b) the nature of the relation (i.e., direct and indirect) between the predictors and listening text comprehension in preschoolers. One-hundred and fifty-two children participated in the present study (68 females; mean age = 4;10 years/months and 5;5 years/months at Time 1 and Time 2, respectively). Participants were administered measures to evaluate listening text comprehension (Time 1 and Time 2) and (a) expressive and receptive word knowledge (lower-level semantic components), and (b) inferential skills and the ability to use context (higher-level semantic components) (Time 1). Verbal short-term and working memory were also included as control variables. Data were analyzed using path analysis models. Results showed that both types of semantic components (a) accounted for unique variance in listening text comprehension at Time 2, with lower-level semantic components explaining a larger proportion of variance than higher-level semantic components; (b) were related to later listening text comprehension through direct and indirect relations. Memory resources did not significantly contribute to listening text comprehension. The results are discussed in light of their theoretical relevance and educational/practical implications. 相似文献

The development of subjective recollection was investigated in participants aged 6-18 years. In Experiment 1 (N = 90), age-related improvements were found in understanding of the subjective experience of recollection, although robust levels of understanding were observed even in the youngest group. In Experiment 2 (N = 100), age-related differences were found in subjective recollection during a memory task, suggesting development not only in the ability to reflect on memory states, but also in the informational basis of subjective recollection. Lower understanding of memory states was associated with increased propensity to claim recollection. These results indicate that subjective recollection develops considerably during childhood and suggest that the development of metamemory supports this capacity. 相似文献
