A proposed scheme for coding infant initiatives during feeding

The conceptual and methodological framework of an observational method designed to measure the interconnectedness between individual development and early relationships is presented. This model is based on our growing understanding of the intense participation of the baby in determining his or her own development. Research on the manifestations of initiatives, environmental responses, and interactive happenings (confrontations, negotiations, encounters) has yielded an instrument defined in several different ways. Twenty-eight mother-infant pairs are presented in this paper. Initiative is considered an important manifestation of the expression of the infant as a differentiated being. It is anticipated that the method presented in this paper will be adequate to measure the development of the infant's self in relationship to his or her environment. It is proposed that the progressive constitution of the self will depend upon an adequate resolution of the basic formula preserving spontaneity/compliance during development. Specific interactive phenomena including negotiation and occurrence of encounters will allow for the identification of particular features of each dyad. An objective of the research is to make predictions about the future development of both the infant as an individual and the dyad.     

Gender segregation in childhood: a test of the interaction style theory.

The authors investigated the play/interaction-style theory of gender segregation with a sample of 39 children aged 2 to 5 years (primarily Caucasian). According to this theory, children prefer playmates with styles of play or interaction that are similar to their own. Because such styles are sex differentiated, same-sex playmate preference (i.e., gender segregation) results. The authors observed children during free play to determine preferred playmates and gender segregation level, and they used teacher ratings to derive play/interaction-style scores. The authors used a multiple regression approach to path analysis to analyze effects of sex of participant, participants' play/interaction-style scores, playmates' play/interaction-style scores, and degree of gender segregation to determine their effects on one another. The authors observed significant levels of gender segregation, with highly aggressive or active children displaying less segregation than their peers did. However, gender segregation was not associated with a preference for playmates with similar play or interaction styles.     

Anticipated action effects affect the selection, initiation, and execution of actions

This study investigated the impact of contingent action effects on response production. In Experiment 1 responses of varying intensity were initiated faster when contingently followed by auditory effects of corresponding rather than of noncorresponding intensity. This response-effect (R-E) compatibility influence was robust with respect to practice, and it was not due to persisting influences of preceding R-E episodes. These results support the conclusion that R-E compatibility reflects the impact of anticipatory effect representations in response production. Experiment 2 showed that anticipatory effect codes have an impact on early processes of response production (response selection) as well as on processes that immediately precede overt responding (response initiation). Finally, they also influence the way the actions are physically performed (response execution). The results support and specify ideo-motor theories of action control that assume movements to be controlled by anticipations of their sensorial effects.     

Levels of Emotional Awareness Scale-Computer

Alexithymia is an important concept in both psychosomatic medicine and emotion research. A valid instrument for the assessment of alexithymia is the Levels Of Emotional Awareness Scale (LEAS; English version by R. Lane, German version by C. Subic-Wrana). Subjects are asked to evaluate in their own words the emotional content of briefly depicted interpersonal situations. Wide use of the LEAS has so far been hampered by a relatively complex evaluation procedure of answers that could not easily be automated. This was the motivation to create a digital version of the LEAS that allows subjects to give their answers directly to the computer and evaluates them automatically (LEAS-C). A custom-made algorithm for text analysis assesses the level of emotional awareness of each answer based on a valid glossary of emotionally relevant words. First data of the application of the LEAS-C in a sample of 187 healthy subjects are reported here. With its high interrater reliability (r=0.86–0.90) compared with human raters, the LEAS-C can be considered a reliable means of assessing alexithymia.     

Examining the Effects of Family and School Social Capital on Delinquent Behavior

In this article we evaluate and compare the effects of social capital at home and social capital at school on the frequency of involvement in delinquent behavior in the previous year. Using data from the first wave of the National Longitudinal Study of Adolescent Health (Add Health, 1994–95; N = 8,100), a nationally representative survey of youth in the United States, we find that social sources of capital in the family exert a stronger negative influence on delinquency than school-based sources of capital, net the effects of other common correlates of this type of adolescent behavior.     

Conscious control over the content of unconscious cognition

Visual stimuli (primes) presented too briefly to be consciously identified can nevertheless affect responses to subsequent stimuli - an instance of unconscious cognition. There is a lively debate as to whether such priming effects originate from unconscious semantic processing of the primes or from reactivation of learned motor responses that conscious stimuli afford during preceding practice. In four experiments we demonstrate that unconscious stimuli owe their impact neither to automatic semantic categorization nor to memory traces of preceding stimulus-response episodes, but to their match with pre-specified cognitive action-trigger conditions. The intentional creation of such triggers allows actors to control the way unconscious stimuli bias their behaviour.
