Organizational self-evaluation: An emerging frontier for organizational improvement

The authors have been working to improve clients’ institutional performance through a framework for institutional assessment and self-assessment. In this framework, performance is defined in terms of mission fulfillment, efficiency, and ongoing relevance (the extent to which the organization adapts to changing conditions in its environment). The framework implies that certain contextual forces drive performance: the internal capacities and motivation of an organization and its external environment. The article presents the framework as well as case studies of several institutions that are using the framework to assess themselves.     

Convenient fixation location within isolated words of different length and structure

When a word is visually presented in a naming or comparison task in such a way that the eye is initially fixated at different locations within the word, a very strong effect of fixation location is found. The effect appears as a U-shaped curve. Naming time and total fixation time (gaze duration) have a minimum for an initial fixation location between the third and fifth letter of the word (for words that are 5-11 letters long). When initial fixation location deviates from this optimum position, times increase at the surprisingly fast rate of 20-30 ms per letter of deviation. By manipulating the internal lexical structure of the words, we show that at least part of the fixation location effect is caused by mechanisms related to ongoing lexical processing. This is demonstrated by the fact that the fixation location effect takes a different form when the most informative part of a word (as determined by dictionary counts) occurs at the beginning or the end of the word.     

Effects of post-trial administration of naloxone and beta-endorphin on shock-induced fighting in rats

To study the involvement of endogenous opioid peptides in the development of shock-induced fighting, naloxone (2 mg/kg) or beta-endorphin (10 micrograms/kg) was administered subcutaneously immediately after the session and during nine consecutive daily sessions to rats repeatedly exposed to electric shocks. beta-Endorphin blocked the development of shock-induced fighting while naloxone facilitated it but only when shock-induced fighting occurred at a low rate. The effects of beta-endorphin were time dependent since when beta-endorphin was injected 90 min after the shock session instead of immediately after, its impairing effect disappeared. In addition, naloxone blocked the impairment produced by beta-endorphin. Differential postsession treatment of each member of pairs of rats with naloxone and beta-endorphin resulted in a higher probability of rats treated with naloxone to be dominant over rats treated with beta-endorphin in the test situation. These results are discussed in relation with the possible involvement of endogenous opioids in the modulation of the physiological consequences of defensive behavioral responses to shock.     

Phonological priming in spoken word recognition: Task effects

In two experiments, we examined the role of phonological relatedness between spoken items using both the lexical decision task and the shadowing task. In Experiment 1, words were used as primes and overlaps of zero (control), one, two, or all four or five (repetition) phonemes were compared. Except for the repetition conditions, in which facilitation was found, phonological overlap resulted in interference on word responses. These effects occurred in both tasks but were larger in lexical decision than in shadowing. The effects that were evident in shadowing can be attributed to an attentional mechanism linked to the subjects' expectancies of repetitions. The extra effects obtained in lexical decision can be interpreted by taking into account both activation of the response corresponding to the prime's lexical status and postlexical processes that check for phonological congruency between prime and target. In Experiment 2, some modifications were introduced to prevent the involvement of strategic factors, and pseudowords were used as primes. No effect at all was observed in shadowing, whereas in lexical decision interference effects occurred, which is consistent with the hypothesis that lexical decision may be negatively affected by finding a phonological discrepancy at the same time as the primed response is reactivated. Neither experiment provided evidence for the occurrence of phonological priming in the perceptual processing of words.     

Identity and sociocultural change: Comparing young indigenous people in Chiapas who have different sociodemographic trajectories

One of the most commonly used distinctions in cross‐cultural studies is the one between individualism and collectivism. One of the criticisms levelled at this distinction is that it fails to incorporate the differences that may exist when comparing people from a rural context with little formal education to people from the same group who live in an urban context where formal education is the norm. Bearing in mind these sociodemographic factors, we have compared the self‐concepts among 104 young indigenous people in Chiapas (Mexico), having divided them into three groups: “rural‐traditional,” “rural–urban” and “urban.” These people's self‐concepts were analysed using a task that contrasts personal self‐concept with social self‐concept and a technique in which participants draw themselves along with the things and people they consider most important to them. The results reveal significant differences between the three groups. The personal categories are given a higher value in the “urban” group while the social categories score higher in the “rural‐traditional” group. Regarding the results of the indigenous self‐portraits, from the content analysis of the drawings, 16 categories emerged. These findings are discussed in the light of Greenfield's theory of social change and human development.     

Predictors of childhood trajectories of overt and indirect aggression: An interdisciplinary approach

The aim of this study was to advance our understanding of the development of aggression in boys and girls by testing a model combining insights from both evolutionary theory and developmental psychology. A sample of 744 children (348 girls) between six and 13 years old was recruited in schools with high deprivation indices. Half of the sample (N = 372; 40.1% girls) had received special educational services for behavioral and/or socio‐emotional problems. Two trajectories for overt aggression and two trajectories for indirect aggression were identified and binomial logistic regressions were used to identify environmental predictors and sex‐specific patterns of these trajectories. Results indicated that peer rejection predicted overt aggression and indirect aggression and that extraversion and male sex predicted overt aggression. The results also showed that interaction between parental practices and some child temperament traits predicted overt aggression (coercion and lack of supervision associated with extraversion or low effortful control) or indirect aggression (coercion and neglect associated with negative affect or low effortful control), and the absence of a father figure predicted high indirect aggression in girls.
