What does the new boss think?: How new leaders' cognitive communities and recent “top-job” success affect organizational change and performance

Leader succession often occurs because a performance decline highlights the need for change within an organization. When this need is especially high, successors are likely to be drawn from different cognitive communities than those of the replaced incumbents. Successors representing different cognitive communities carry out more change immediately after succession. This increased, rapid change will be most effective when the new leaders have had successful recent “top-job” experience. When successors lack recent top-job success, too much change too soon will actually hurt performance. We find moderate support for these relationships using panel data from the USA's National Football League.

Secure attachment and social and personality outcomes: The moderating role of emerging adults’ autobiographical memories of parents

Schema-congruent positive autobiographical memories of past experiences with parents, a legacy of secure attachment, may operate jointly with secure attachment to predict social and personality outcomes. The current study examines the moderating role of emerging adults’ autobiographical memories of parents on the relations between maternal and paternal attachment and self-regulation, personal distress, and pathological narcissism. Undergraduates (N = 156, 66.7% female, 53.2% White, M_age = 19.3) completed a battery of measures assessing secure attachment, self-regulation, personal distress, and pathological narcissism (vulnerable and grandiose). Participants were instructed to recall brief autobiographical memories of experiences with their parental figures. Later, they were asked to name the primary emotion associated with each memory. These emotions were coded as positive, negative, or neutral in valence. For the final analysis, a positive emotion index was constructed by subtracting the number of negative memories from the number of positive memories. Regression models simultaneously examining four outcomes (self-regulation, personal distress, and vulnerable and grandiose narcissism) were examined for both female and male parental figures. Interactions between secure attachment and positive memories were only significant for maternal model outcomes. Secure attachment was positively related to self-regulation, and negatively related to personal distress and vulnerable narcissism, when more relative positive memories were recalled. Taken together, this study provides support for the continued influence of secure attachment on social and personality outcomes in emerging adulthood. Further, this influence of secure attachment appears buttressed by readily accessible positive (relative to negative) memories of female attachment figures.     

Rule learning transfer across linguistic and visual modalities in 7-month-old infants

Rule learning (RL) refers to infants’ ability to extract high-order, repetition-based rules from a sequence of elements and to generalize them to new items. RL has been demonstrated in both the auditory and the visual modality, but no studies have investigated infants’ transfer of learning across these two modalities, a process that is fundamental for the development of many complex cognitive skills. Using a visual habituation procedure within a cross-modal RL task, we tested 7-month-old infants’ transfer of learning both from speech to vision (auditory-visual—AV—condition) and from vision to speech (visual-auditory—VA—condition). Results showed a transfer of learning in the AV condition, but only for those infants who were able to efficiently extract the rule during the learning (habituation) phase. In contrast, in the VA condition infants provided no evidence of RL. Overall, this study indicates that 7-month-old infants can transfers high-order rules across modalities with an advantage for transferring from speech to vision, and that this ability is constrained by infants’ individual differences in the way they process the to-be-learned rules.
