Compliance Dynamics Within a Friendship Network II: Structural Positions Used to Garner Social Support

Social networks play a critical role in people's responses to influence attempts, determining whether a person seeks the support of others as an alternative to compliance or as a way to cope with being the target of an influence attempt. In 2 experiments (N = 458 and N = 105), sociograms were used to represent social relationships and to investigate the social network member who would be sought for social support after an influence attempt. Results showed that targets were seen as likely to seek social support in more threatening situations and from more useful (e.g., powerful, connected) network members. Differences found in the 2 experiments appear to represent differences between intergroup and intragroup networks.     

Mechanisms underlying accent accommodation in early word learning: evidence for general expansion

Previous work reveals that toddlers can accommodate a novel accent after hearing it for only a brief period of time. A common assumption is that children, like adults, cope with nonstandard pronunciations by relying on words they know (e.g. ‘this person pronounces sock as sack, therefore by black she meant block’). In this paper, we assess whether toddlers might additionally use a general expansion strategy, whereby they simply accept non‐standard pronunciations when variability is expected. We exposed a group of 24‐month‐old English‐learning toddlers to variability in indexical cues (very diverse voices from native English talkers), and another to variability in social cues (very diverse‐looking silent actors); neither group was familiarized with the target novel accent. At test, both groups succeeded in recognizing a novel word when spoken in the novel accent. Thus, even when no lexical cues are available, variability can prepare young children for non‐standard pronunciations.     

So many options,so little time: The roles of association and competition in underdetermined responding

How do we make decisions when faced with multiple options? In the domain of language, some evidence suggests that we exert cognitive control in order to respond in such underdetermined situations when a good option is hard to find but not when we must select among competing options. However, this conclusion, and conclusions about the neural substrates supporting underdetermined responding, are made on the basis of measures that confound retrieval and selection demands. The present study introduces measures based on latent semantic analyses that better capture the underlying theoretical constructs of association strength and competition. These measures revealed independent effects of retrieval and selection demands on reaction times in verb generation and sentence completion tasks. These results challenge existing accounts of underdetermined responding and highlight the need for unconfounded measures of association strength and competition in studies of localization. We propose a new model governed by both absolute and relative activation levels of alternative responses. 2008 Psychonomic Society, Inc. Author Note     

Infants discriminate manners and paths in non-linguistic dynamic events

Do 14- to 17-month-olds notice the paths and manners of motion events? English- and Spanish-learning infants were habituated to an animated motion event including a manner (e.g., spinning) and a path (e.g., over). They were then tested on four types of events that changed either the manner, the path, both, or neither component. Both English- and Spanish-learning infants attended to changes of manner and changes of path. Thus, infants from two different language communities proved sensitive to components of events that undergird relational term learning.     

Reducing rapid eating in teenagers with autism: use of a pager prompt

This study assessed the effects of a vibrating pager for increasing the duration of meal consumption in 3 teenagers with autism who were observed to eat too quickly. Participants were taught to take a bite only when the pager vibrated at predetermined intervals. A reversal design indicated that the vibrating pager successfully increased the total duration of mealtime, thereby slowing the pace of consumption for all 3 participants.     

Coping with negative social identity: the case of Mexican immigrants

Social identity theory suggests that an individual's self-concept is shaped through group identification and positive social identities are established by favorably comparing the individual's in-group against an out-group. When unfavorable intergroup comparisons occur, individuals perceive a negative social identity. Because of the motivation to maintain a positive self-concept, this perception creates a need to cope. On the basis of face-to-face interviews with Mexican immigrants, the author examined the ways in which negative social-identity perceptions triggered different coping mechanisms. The findings offer support for two coping mechanisms--individual mobility and social creativity, with social creativity used more often than individual mobility.
