Choosing an inferior alternative

We show how decision makers can be induced to choose a personally inferior alternative, a strong violation of rational decision making. First, the inferior alternative is installed as the leading option by starting with information that supports this alternative. Then, the decision maker uses the natural process of distorting new information to support whichever alternative is leading. This leader-supporting distortion overcomes the inherent advantages of the superior alternative. The end result is a tendency to choose the self-identified inferior alternative. We trace the choice process to reveal the amount of distortion and its influence on preference. Self-reported awareness of distortion to support the inferior alternative is not related to the amount of distortion. The absence of valid awareness suggests that the manipulation that produces this preference violation is unlikely to be detected and that the distortion is unlikely to be corrected by the decision maker. As expected, given the lack of awareness, final confidence is just as high when the inferior alternative is chosen as when the superior one is. The discussion considers how to prevent an adversary from manipulating one's decisions using this technique.     

Tracking the what and why of speakers’ choices: Prosodic boundaries and the length of constituents

The rational speaker hypothesis (Clifton, Carlson, & Frazier, 2002) claims that speakers are selfconsistent, employing intonation in a manner consistent with their intended message. Preceding a constituent by a prosodic boundary that is not required by the grammar often signals that this constituent is not part of the immediately preceding phrase. However, speakers tend to place prosodic boundaries before and after long constituents. The question is whether prosodic boundaries will have a larger influence on listeners’ choice of an analysis when they flank short constituents than when they flank long ones. The results of two listening experiments indicate that they do, suggesting that listeners attend not just to properties of the input signal, but also to the reasons why speakers produce those properties.     

Developmental changes in perceptions of attractiveness: a role of experience?

In three experiments, we traced the development of the adult pattern of judgments of attractiveness for faces that have been altered to have internal features in low, average, or high positions. Twelve-year-olds and adults demonstrated identical patterns of results: they rated faces with features in an average location as significantly more attractive than faces with either low or high features. Although both 4-year-olds and 9-year-olds rated faces with high features as least attractive, unlike adults and 12-year-olds, they rated faces with low and average features as equally attractive. Three-year-olds with high levels of peer interaction, but not those with low levels of peer interaction, chose faces with low features as significantly more attractive than those with high-placed features, possibly as a result of their increased experience with the proportions of the faces of peers. Overall, the pattern of results is consistent with the hypothesis that experience influences perceptions of attractiveness, with the proportions of the faces participants see in their everyday lives influencing their perceptions of attractiveness.     

Prosodic phrasing is central to language comprehension

Words, like musical notes, are grouped together into phrases by their rhythmic and durational properties as well as their tonal pitch. This 'prosodic phrasing' affects the understanding of sentences. Many processing studies of prosody have investigated sentences with a single, grammatically required prosodic boundary, which might be interpreted strictly locally, as a signal to end the current syntactic unit. Recent results suggest, however, that the global pattern of prosodic phrasing is what matters in sentence comprehension, not just the occurrence or size of a single local boundary. In this article we claim that the impact of prosodic boundaries depends on the other prosodic choices a speaker has made. We speculate that prosody serves to hold distinct linguistic representations together in memory.     

Less is more: executive function and symbolic representation in preschool children

Executive function is recognized as a critical component of children's cognitive and social development. In two studies, a measure of executive function that had been used in research with chimpanzees was adapted for preschoolers. On this task, called Less Is More, children must point to a smaller reward (two candies) to receive a larger reward (five candies). In Study 1 (N= 101), performance was significantly related to age (3 vs. 4), verbal ability, and established measures of executive function. In Study 2 (N= 128), symbolic representations substituted for real candies in this task. Three-year-olds' performance improved significantly as a function of symbolic distancing. This research has implications for the role of symbol systems in the development of executive control over thought and action.     

Temperament, relationships, and young children's receptive cooperation with their parents

The authors studied receptive cooperation--a willing, eager stance toward parents--in 15-month-old children (N = 101) in broadly ranging contexts. Children's anger proneness and parents' responsiveness (both observed at 7 months) and children's attachment security (assessed in Strange Situation at 15 months) were examined as predictors of children's receptive cooperation at 15 months. In mother-child dyads, secure attachment was strongly associated with children's higher receptive cooperation. Maternal responsiveness in infancy also promoted children's future receptive cooperation, but its impact was moderated by child anger: Responsiveness had a positive effect for children who as infants were highly anger prone. In father-child dyads, the negative effect of anger proneness on receptive cooperation with father was significantly amplified for insecure children. Mother's responsiveness and child's secure attachment to the mother promoted child receptive cooperation with the father, but there were no similar effects for fathers.     

Etiologic connections among substance dependence,antisocial behavior,and personality: modeling the externalizing spectrum

A hierarchical biometric model is presented of the origins of comorbidity among substance dependence, antisocial behavior, and a disinhibited personality style. The model posits a spectrum of personality and psychopathology, united by an externalizing factor linked to each phenotype within the spectrum, as well as specific factors that account for distinctions among phenotypes within the spectrum. This model fit self-report and mother-report data from 1,048 male and female 17-year-old twins. The variance of the externalizing factor was mostly genetic, but both genetic and environmental factors accounted for distinctions among phenotypes within the spectrum. These results reconcile evidence for general and specific causal factors within the externalizing spectrum and offer the externalizing factor as a novel target for future research.     

Inhibition of attended processing during saccadic eye movements

People are unable to perform some, but not all, cognitive tasks while moving their eyes. A possible common denominator among disrupted processes is the use of attention. The present research proposes and tests an attentional suppression hypothesis to evaluate this claim. This hypothesis states that because attention is obligatorily allocated to a to-be-fixated location prior to the onset of a saccade, during saccadic events attentional resources are unavailable to direct processing associated with higher order cognitive tasks. Subjects were engaged in a task that combined saccades and shifts of attention across global and local levels of hierarchical figures. When the eyes did not move, this shift took place between stimulus presentations. When saccades intervened between the stimuli, the global-local shifts of attention were interrupted, suggesting that saccades suppress cognitive processes requiring attention.     

Ukrainian Application of the Children's Somatization Inventory: Psychometric Properties and Associations With Internalizing Symptoms

This paper examines the psychometric properties of the Children's Somatization Inventory (CSI) in 600 10–12-year old children in Kyiv, Ukraine, replicating and extending the original findings from a sample in Nashville, Tennessee (J. Garber et al. 1991). The Kyiv children had significantly lower CSI total scores and reported significantly fewer symptoms than the American children. The Kyiv mothers, however, reported significantly more somatization symptoms in their children than did the American mothers. A factor analysis of the children's data yielded four similar factors encompassing pseudoneurologic, cardiovascular, gastrointestinal, and pain/weakness symptoms. Consistent with the findings from the Nashville study, the CSI was significantly related to the children's self-reports of health and depressive and anxiety symptoms and to maternal reports of child depression and anxiety symptoms. In addition, although more children with the highest CSI scores (25+) reported various illness experiences than those with 0–1 symptoms, no differences were found in the school absentee records. Thus, the results were congruent with the findings of the Nashville study, indicating that the CSI reliably measured somatization in this Ukrainian sample.     

Disappointment for others

Two studies examined when and why people experience disappointment for others. Study 1 demonstrated that participants reported disappointment for another's outcome only when the outcome had strong personal implications. Study 2 demonstrated that self-image concerns rather than empathy or resource concerns mediated the experience of disappointment for others. Collectively, these findings suggest that people experience disappointment for others when those outcomes implicate the self-image.
