The many faces of the Still-Face Paradigm: A review and meta-analysis

The Still-Face Paradigm (SFP) designed by Tronick, Als, Adamson, Wise, and Brazelton (Tronick, E., Als, H., Adamson, L., Wise, S., & Brazelton, T. B. (1978). Infants response to entrapment between contradictory messages in face-to-face interaction. Journal of the American Academy of Child and Adolescent Psychiatry, 17, 1–13) has been used for many different purposes in over 80 empirical studies. In the current paper, the nature and correlates of infant behavior in the SFP were examined in a systematic narrative review and a series of meta-analyses. The results of the meta-analyses confirmed the classic still-face effect of reduced positive affect and gaze, and increased negative affect, as well as a partial carry-over effect into the reunion episode consisting of lower positive and higher negative affect compared to baseline. The still-face effect is very robust as it was found regardless of most sample variations such as infant gender and risk status, and regardless of most procedural variations, such as the length of the SFP episodes and the use of intervals between episodes. The few moderator effects that were found in the meta-analyses tended to put findings from the narrative review in a new perspective. Additional meta-analyses confirmed the narrative review in finding that higher maternal sensitivity predicted more infant positive affect during the still-face. Infants’ higher positive affect and lower negative affect during the still-face were predictive of secure attachment at age 1 year. The meta-analytic results for maternal depression were equivocal. Implications for future research include a need for studies testing the role of the adults’ identity (parent versus stranger, mother versus father) to elucidate the relationship-specificity of the still-face effect. Also, the role of maternal sensitivity and temperament as potential moderators of the still-face effect need to be examined further. On a procedural level, the effects of the timing of the still-face and of the duration of the reunion on infant responses deserve future research attention.     

The bilingual advantage in novel word learning

The present study examined whether bilingualism facilitates acquisition of novel words in adults with different language histories. Word-learning performance was tested in monolingual English speakers, early English—Spanish bilinguals, and early English—Mandarin bilinguals. Novel words were phonologically unfamiliar to all participants, and they were acquired in association with their English translations. At testing, both bilingual groups outperformed the monolingual group. These findings indicate that bilingualism facilitates word-learning performance in adults, and they suggest a general bilingual advantage for novel word learning.     

Some surprising findings on the involvement of the parietal lobe in human memory

The posterior parietal lobe is known to play some role in a far-flung list of mental processes: linking vision to action (saccadic eye movements, reaching, grasping), attending to visual space, numerical calculation, and mental rotation. Here, we review findings from humans and monkeys that illuminate an untraditional function of this region: memory. Our review draws on neuroimaging findings that have repeatedly identified parietal lobe activations associated with short-term or working memory and episodic memory. We also discuss recent neuropsychological findings showing that individuals with parietal lobe damage exhibit both working memory and long-term memory deficits. These deficits are not ubiquitous; they are only evident under certain retrieval demands. Our review elaborates on these findings and evaluates various theories about the mechanistic role of the posterior parietal lobe in memory. The available data point towards the conclusion that the posterior parietal lobe plays an important role in memory retrieval irrespective of elapsed time. However, the available data do not support simple dichotomies such as recall versus recognition, working versus long-term memory. We conclude by formalizing several open questions that are intended to encourage future research in this rapidly developing area of memory research.     

Explanations of success and derailment in upper-level management positions

Using an inventory based on findings from several qualitative studies, this investigation developed eight dimensions distinguishing successful senior managers from those who had derailed. Results showed that bosses' ratings of 86 successful senior managers on the eight dimensions were significantly higher than those of 83 who had derailed, providing empirical support for many of the earlier qualitative findings. Comparing the successful managers to the derailed suggests dimensions otherwise overlooked which are important to consider when assessing managerial talent.     

Resolutions of control episodes between well and affectively ill mothers and their young children

Control interactions between 87 well and affectively ill mothers and their 15- to 51-month-old children were studied. Spontaneously occurring control interventions (conceptualized as episodes of interaction between mother and child) were coded from 90 minutes of videotaped interactions in a naturalistic laboratory apartment setting. The results suggest developmental changes in mother-child interaction in the 2nd to 4th years of life: the increase of the rate of immediate maternal success (p less than .05) and compromise (p less than .05), on the decrease in maternal use of power (ultimate success by enforcement, p less than .01). Well mothers achieved compromise with their children, particularly daughters, more often than did affectively ill mothers (p less than .05). Affectively ill mothers more often than well mothers avoided confrontation with their children (p less than .05). The impairments in control interventions of affectively ill mothers were exacerbated by the severity of the disorder.
