Understanding the effects of one's actions upon hidden objects and the development of search behaviour in 7‐month‐old infants

Infants' understanding of how their actions affect the visibility of hidden objects may be a crucial aspect of the development of search behaviour. To investigate this possibility, 7‐month‐old infants took part in a two‐day training study. At the start of the first session, and at the end of the second, all infants performed a search task with a hiding‐well. On both days, infants had an additional training experience. The ‘Agency group’ learnt to spin a turntable to reveal a hidden toy, whilst the ‘Means‐End’ group learnt the same means‐end motor action, but the toy was always visible. The Agency group showed greater improvement on the hiding‐well search task following their training experience. We suggest that the Agency group's turntable experience was effective because it provided the experience of bringing objects back into visibility by one's actions. Further, the performance of the Agency group demonstrates generalized transfer of learning across situations with both different motor actions and stimuli in infants as young as 7 months.     

Gender Role Attitudes across the Transition to Adolescent Motherhood in Mexican‐Origin Families

Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families.     

Constructions of Mexican American family grief after the death of a child: an exploratory study

Using a collective case study ethnographic approach, nine individuals comprising three Mexican American families were interviewed about their family bereavement experiences after the death of a child. All families were Catholic, had surviving siblings, and had had three or more years to grieve their loss when interviewed. The deceased children ranged in age from 3 to 14, and all experienced sudden, traumatic, nonsuicide deaths. To provide a broader, contextual picture of their grief experiences, four individuals who supported these family members after the loss were also interviewed. Unique grief experiences were identified, and eight common themes emerged, reflecting the ways in which family members maintained their bond to the deceased: dreams, storytelling, keepsakes, sense of presence, faith-based connections, proximity connections, ongoing rituals, and pictorial remembrances. The cultural implications of family bereavement are highlighted.     

Choosing among alternative parties to be sponsored for supporting brand strategies,based upon emotional responses

• In recent years, much research has been concerned with the effects of sponsorships and the possible advantages a company can gain from engaging in sponsoring activities. Recently focus has been on the role, that sponsoring plays in branding strategy. Here it becomes important to understand exactly what a potential party to be sponsored contributes to the perception of a brand or a company. In this paper, the aim has been reversed to focus on the sponsored party. We propose a number of measurements to determine emotional responses and overall evaluations associated with a sponsored party who is a part of a sponsorship agreement with a company. Four different groups of parties to be sponsored are investigated: social aid organisations, culture, sport and TV‐programmes. Several interesting results emerged from this study; the parties to be sponsored were evaluated very differently on the dimensions used in the study and it is shown that a company can gain very different results depending on the type of object to choose to sponsor. Furthermore, it was shown that the overall evaluation of a party to be sponsored to a large extent is determined by emotions. Copyright © 2006 John Wiley & Sons, Ltd.

     

Can cognitive processes be inferred from neuroimaging data?

There is much interest currently in using functional neuroimaging techniques to understand better the nature of cognition. One particular practice that has become common is 'reverse inference', by which the engagement of a particular cognitive process is inferred from the activation of a particular brain region. Such inferences are not deductively valid, but can still provide some information. Using a Bayesian analysis of the BrainMap neuroimaging database, I characterize the amount of additional evidence in favor of the engagement of a cognitive process that can be offered by a reverse inference. Its usefulness is particularly limited by the selectivity of activation in the region of interest. I argue that cognitive neuroscientists should be circumspect in the use of reverse inference, particularly when selectivity of the region in question cannot be established or is known to be weak.     

Learning words: children disregard some pragmatic information that conflicts with mutual exclusivity

Children tend to infer that when a speaker uses a new label, the label refers to an unlabeled object rather than one they already know the label for. Does this inference reflect a default assumption that words are mutually exclusive? Or does it instead reflect the result of a pragmatic reasoning process about what the speaker intended? In two studies, we distinguish between these possibilities. Preschoolers watched as a speaker pointed toward (Study 1) or looked at (Study 2) a familiar object while requesting the referent for a new word (e.g. ‘Can you give me the blicket?’). In both studies, despite the speaker's unambiguous behavioral cue indicating an intent to refer to a familiar object, children inferred that the novel label referred to an unfamiliar object. These results suggest that children expect words to be mutually exclusive even when a speaker provides some kinds of pragmatic evidence to the contrary.     

Lateralized scratching in chimpanzees (Pan troglodytes): Evidence of a functional asymmetry during arousal

This study evaluated laterality in scratching by chimpanzees (n = 89) during socially arousing circumstances. Hand use and the side of the body scratched was recorded during a baseline and experimental condition. In the experimental condition, chimpanzees were shown a video of other conspecifics sharing, fighting over, and consuming a watermelon. Self-touches were categorized as either rubs or scratches. The chimpanzees showed a significant right hand bias for rubbing and also significantly directed the rubs to the right side of the body. For scratching, the chimpanzees showed no hand preference but a significant bias for scratching on the left side of the body. These results support the view that the right hemisphere regulates the autonomic nervous system during arousal.     

Language and the perception of emotion

Three studies assessed the relationship between language and the perception of emotion. The authors predicted and found that the accessibility of emotion words influenced participants' speed or accuracy in perceiving facial behaviors depicting emotion. Specifically, emotion words were either primed or temporarily made less accessible using a semantic satiation procedure. In Studies 1 and 2, participants were slower to categorize facial behaviors depicting emotion (i.e., a face depicting anger) after an emotion word (e.g., "anger") was satiated. In Study 3, participants were less accurate to categorize facial behaviors depicting emotion after an emotion word was satiated. The implications of these findings for a linguistically relative view of emotion perception are discussed.
