Sequential compatibility effects and cognitive control: does conflict really matter?

Although it is widely accepted that control mechanisms are necessary for human behavior to be adapted, very little is known about how such mechanisms are recruited. A suggestion to fill the gap was put forward by M. M. Botvinick, T. S. Braver, C. S. Carter, D. M. Barch, and J. D. Cohen (2001), who proposed the conflict-loop theory. This theory has been successful in accounting for the reduction of compatibility effects after an incompatible trial: The level of conflict being, on average, higher during an incompatible trial, more control occurs after such a trial. The authors have tested this prediction by sorting the trials on the basis of amount of conflict (quantified by the electromyographic activity) they presented. A reduction of the compatibility effect was observed after incompatible trials, but it was independent of the level of conflict on previous trials, suggesting that the conflict does not trigger changes in executive control. Consequences for the conflict monitoring model are discussed.     

Psychological Determinants of Optimism Regarding Consequences of the War

Gazing behavior of 10 three-month-old twin infants (five male and five female) and their mothers during play, bottle feeding, and spoon feeding activities were analyzed. Video-tape equipment was used in the home; data were gathered as naturalistically as possible. Mothers looked at infants for a greater percentage of the total time and for longer durations than infants looked at mothers. A consistency-activation personality theory in which mothers are highly motivated to gaze at infants, but infants seek visual interest by looking away from mother, is suggested to interpret the findings. Both looking and not-looking gazes and mean and median measures of central tendency were shown to be helpful and necessary for the gazing analysis.     

A study of sharing and reciprocity in grey parrots (Psittacus erithacus)

Demonstrations of nonhuman ability to share resources and reciprocate such sharing seem contingent upon the experimental paradigm used (note Horner et al. in PNAS 108:13847–13851, 2011). Here, such behaviour in Grey parrots (Psittacus erithacus) was tested in two experiments, both designed to avoid possible issues involving apparatus complexity, visible reward options, and physical competition and/or limited communication between subjects. In both studies, two birds, working in dyads, took turns in choosing one of four different coloured cups with differing outcomes: empty (null, nonrewarding), selfish (keeping reward for oneself), share (sharing a divisible reward), or giving (donating reward to other). In Experiment 1, each bird alternated choices with a conspecific; in Experiment 2, each bird alternated with the three humans with different specific intentions (selfish, giving, or copying bird’s behaviour). In both experiments, birds could learn to cooperatively reward a partner at little cost to themselves—by sharing—and potentially maximize overall reward by reciprocating such sharing. Experiment 1 results differed depending upon which bird began a session: Only our dominant bird, as follower, was willing to share. In Experiment 2, birds’ responses tended towards consistency with human behaviour. Our dominant bird was willing to share a reward with a human who was willing to give up her reward, was selfish with the selfish human, and tended towards sharing with the copycat human; our subordinate bird tended slightly towards increased sharing with the generous human and selfishness with the selfish human, but did not change behaviour with the copycat.     

Individual Pathways Through the Junior-to-Senior Transition: Narratives of Two Swedish Team Sport Athletes

Athletes frequently describe the junior-to-senior transition (JST) as the most difficult within-career transition, and many athletes have acknowledged that they failed to cope well with it. Athletes’ development in the JST is influenced by narratives existing within relevant contexts and settings. This study served as a follow-up to the quantitative longitudinal study to gain a deeper understanding of individual JST paths through a qualitative narrative approach. The aim was to explore 2 team sport athletes’ (John, the football player, and Anna, the basketball player) JST pathways, emphasizing psychosocial factors that were perceived as facilitating and debilitating the process. Narrative type interviews were conducted, and the holistic-form structural analysis was used. Through their narratives, John and Anna reconstructed their JST paths, attaching meanings to certain events, recounting the people involved, and making personal reflections. John had a performance and family narrative and Anna had an enjoyment and relationship narrative. They perceived their key facilitating persons to be their family members and teammates. The debilitating factors were some coaches’ behaviors. At the time of this study, John and Anna had already terminated their athletic careers and had refocused on getting an education. Although they did not reach elite senior levels in their sports, they found their athletic careers to be meaningful life experiences.

Lay Summary: The aim was to explore two team sport athletes’ junior-to-senior transition (JST) pathways, emphasizing psychosocial factors involved in the transition process. The findings revealed two narratives. John (football player) storied his JST as a performance and family narrative and Anna (basketball player) as an enjoyment and relationship narrative.
