Phrasing Effects in Comprehending PP Constructions

The role of prosodic phrasing in sentence comprehension was investigated by means of three different tasks, namely auditory word monitoring (Experiment 1), self-paced reading (Experiment 2) and cross-modal comparison (Experiment 3). In all three experiments a critical prosodic unit or frame comprising a determiner, a noun and a Prepositional Phrase (PP) was preceded or surrounded by two context prosodic units (frames) whose length was varied. The participants’ tendency to interpret the critical sequence as forming a single syntactic constituent (noun–complement interpretation of the PP) as opposed to two distinct syntactic constituents (verb–complement interpretation of the PP) was found to depend on the relative length of the critical and context prosodic units (frames). As a whole these results are consistent with the notion that phrasing effects occur in a retroactive way, after part of the utterance has been processed.     

Relationship Quality of Aggressive Children and Their Siblings: A Multiinformant, Multimeasure Investigation

Sibling influence on the learning and enactment of aggressive behavior has been consistently demonstrated in studies of sibling relationships. Available evidence suggests that, compared with nonaggressive children's sibling interactions, the sibling interactions of aggressive children are marked by more frequent, intense, and prolonged aggressive behaviors. Although research on normative and aggressive children's sibling interactions has increased recently, a number of limitations in this literature were addressed in this study by: (1) including both an aggressive and nonaggressive comparison group, (2) examining both positive and negative features of sibling relationships, (3) employing a multimethod/multiinformant approach to data collection, and (4) utilizing an improved self-report method. In support of our hypotheses and consistent with previous research, results showed that aggressive children's sibling relationships were marked by higher levels of observed conflict and lower levels of self-reported positive features. When gender was examined, results showed that older brother/younger sister dyads were characterized by higher levels of negative features and lower levels of positive features.     

Open source standardization: The rise of linux in the network era

To attract complementary assets, firms that sponsor proprietary de facto compatibility standards must trade off control of the standard against the imperative for adoption. For example, Microsoft and Intel in turn gained pervasive adoption of their technologies by appropriating only a single layer of the standards architecture and encouraging competition in other layers. In reaction to such proprietary strategies, the open source movement relinquished control to maximize adoption. To illustrate this, we examine the rise of the Linux operating system from 1995–2001, particularly the motivations of organizational buyers and suppliers of complementary assets, and Microsoft’s reaction to its success.     

More accurate size contrast judgments in the Ebbinghaus Illusion by a remote culture

The Ebbinghaus (Titchener) illusion was examined in a remote culture (Himba) with no words for geometric shapes. The illusion was experienced less strongly by Himba compared with English participants, leading to more accurate size contrast judgments in the Himba. The study included two conditions of inducing stimuli. The illusion was weaker when the inducing stimuli were dissimilar (diamonds) to the target (circle) compared with when they were similar (circles). However, the illusion was weakened to the same extent in both cultures. It is argued that the more accurate size judgments of the Himba derive from their tendency to prioritize the analysis of local details in visual processing of multiple objects, and not from their impoverished naming.     

Age differences in item manipulation span: the case of letter-number sequencing

The authors report 2 experiments in which they examined age differences in working memory tasks involving complex item manipulation (i.e., letter-number sequencing). In Experiment 1, age differences on tasks involving item manipulation were not greater than age differences on tasks requiring recall of items in the order in which they appeared, suggesting that older adults do not have difficulty with item manipulation per se. In Experiment 2, slower presentation rates increased age differences in item manipulation spans, although age differences at the fastest rate may be attributed to differences in strategy use. In both experiments, age differences were largest when participants were most likely to be remembering familiar sequences, suggesting that older adults may have difficulties dampening the representations of such sequences once they are activated.
