Sexual Subjectivity: A Semiotic Analysis of Girlhood, Sex, and Sexuality in the Film Juno

Historical approaches to girlhood provide a basis for understanding changing cultural ideologies of sex, sexuality, and youth. While situating sexual desire, biological possibilities, and social responses to girls’ engagement in sexual intercourse at the center of its plot, the film Juno depicts the transgressive sexual agency of a young girl without substantially disrupting longstanding discourses of femininity. Through an analysis of the semiotics of girlhood within the film, I argue that the girl figure in this representation signifies an amalgam of two traditionally dichotomized conceptions of “femininity.” Juno serves as a particularly intriguing example of the ways in which adolescent female sexuality is conceptualized within popular western culture during the early part of the 21st century.

Cognitive control factors in speech perception at 11 months

The development of speech perception during the 1st year reflects increasing attunement to native language features, but the mechanisms underlying this development are not completely understood. One previous study linked reductions in nonnative speech discrimination to performance on nonlinguistic tasks, whereas other studies have shown associations between speech perception and vocabulary growth. The present study examined relationships among these abilities in 11-month-old infants using a conditioned head-turn test of native and nonnative speech sound discrimination, nonlinguistic object-retrieval tasks requiring attention and inhibitory control, and the MacArthur-Bates Communicative Development Inventory (L. Fenson et al., 1993). Native speech discrimination was positively linked to receptive vocabulary size but not to the cognitive control tasks, whereas nonnative speech discrimination was negatively linked to cognitive control scores but not to vocabulary size. Speech discrimination, vocabulary size, and cognitive control scores were not associated with more general cognitive measures. These results suggest specific relationships between domain-general inhibitory control processes and the ability to ignore variation in speech that is irrelevant to the native language and between the development of native language speech perception and vocabulary.     

Individual differences: Factors affecting employee utilization of flexible work arrangements

This study investigated individual and organizational factors that predict an individual’s choice to use flexible work arrangements (FWAs). Survey data was collected from 144 employees in two different organizations. The results revealed several significant predictors of FWAs: tenure, hours worked per week, supervisory responsibilities, perceptions of workgroup use and personal lifestyle. Individuals with longer tenure in the organization, who had supervisory responsibilities, had coworkers in their immediate workgroup who used FWAs or had personal lifestyle preferences were more likely to use the programs than those with less tenure, who did not have supervisory responsibilities, did not perceive their workgroup used FWAs or did not have personal lifestyle preferences.     

Role ambiguity and self-efficacy: The moderating effects of goal orientation and procedural justice

The present study investigated variables that moderated the relationship between role ambiguity and self-efficacy. Results of a field study found support for the moderating role of learning goal orientation, such that the relationship between role ambiguity and self-efficacy was weaker when learning goal orientation was high. In addition, we found that procedural justice moderated the role ambiguity—self-efficacy relationship, such that the relationship was stronger when procedural justice was high. However, contrary to our prediction, avoiding goal orientation did not interact with role ambiguity to predict self-efficacy. Implications of these findings for theory and practice are discussed.     

The role of stability in the dynamics of learning, memorizing, and forgetting new coordination patterns

According to a dynamic theory of learning, how a new memory is formed depends on the stability of the nearest preexisting memories. To predict retention after practice, the authors analyzed how 15 participants memorized 2 bimanual coordination patterns (45 degrees or 135 degrees relative phase). The authors assessed (a) how participants memorized the required patterns with learning and (b) how the associated memory layout evolved. Results showed that a practiced 45 degrees pattern near a very stable memory (0 degrees ) persisted, whereas a 135 degrees pattern near a less stable memory (180 degrees ) was forgotten. Those findings corroborate the proposition that retention of coordination patterns depends on the stability of the extant motor memories. The authors discuss that proposal in terms of the coevolution of accuracy and stability with learning to predict persistence of required or false memories.     

Depressed Adolescents and Comorbid Psychiatric Disorders: Are There Differences in the Presentation of Depression?

Patterns and correlates of comorbidity, as well as differences in manifest depressive profiles were investigated in a sample of depressed adolescents. A sub-sample of the youth were characterized as belonging to either a Pure depression group, an Internalizing group (depression and co-occurring internalizing disorders), or an Externalizing group (depression and co-occurring externalizing disorders). Item response theory (IRT) and differential item functioning (DIF) were used to assess whether the depressed adolescents from the different comorbidity groups presented with different depressive symptoms. Results indicated that the comorbidity groups were meaningfully distinct in terms of psychosocial correlates as well as showed differences in depressive symptom profiles as informed by DIF analyses. In particular, the comorbidity groups differed in terms of presentation of psychomotor changes and cognitive impairments. Implications for assessment are discussed.

The weckud wetch of the wast: lexical adaptation to a novel accent

Two experiments investigated the mechanism by which listeners adjust their interpretation of accented speech that is similar to a regional dialect of American English. Only a subset of the vowels of English (the front vowels) were shifted during adaptation, which consisted of listening to a 20-min segment of the "Wizard of Oz." Compared to a baseline (unadapted) condition, listeners showed significant adaptation to the accented speech, as indexed by increased word judgments on a lexical decision task. Adaptation also generalized to test words that had not been presented in the accented passage but that contained the shifted vowels. A control experiment showed that the adaptation effect was specific to the direction of the shift in the vowel space and not to a general relaxation of the criterion for what constitutes a good exemplar of the accented vowel category. Taken together, these results provide evidence for a context-specific vowel adaptation mechanism that enables a listener to adjust to the dialect of a particular talker.     

Environmental stimulation, parental nurturance and cognitive development in humans

The effects of environmental stimulation and parental nurturance on brain development have been studied extensively in animals. Much less is known about the relations between childhood experience and cognitive development in humans. Using a longitudinally collected data set with ecologically valid in-home measures of childhood experience and later in-laboratory behavioral measures of cognitive ability, we were able to test hypotheses concerning the effects of environmental stimulation and parental nurturance. A double dissociation was found: On the one hand, there was a selective relation between parental nurturance and memory development, consistent with the animal literature on maternal buffering of stress hormone effects on hippocampal development. On the other hand, there was a selective relation between environmental stimulation and language development. The relevance of these findings to socioeconomic gradients in cognitive ability is discussed.     

Feeling Transparent: On Metaperceptions and Miscommunications

Individuals’ metaperceptions regarding how another person views them tend to be egocentrically biased by their own private self‐knowledge: They overestimate the extent to which their traits, feelings, and intentions are ‘transparent’, perceiving more congruence between their inner self and the other person's impressions than actually exists. In the present article, we examine the factors, such as self‐awareness and feelings of closeness, that increase individuals’ propensity to exaggerate their transparency to others. We also examine the interpersonal consequences of transparency overestimation and the related signal amplification bias, considering how they can reduce the likelihood of relationship formation, derail the seeking and provision of social support in ongoing relationships, and more generally lead to relational conflict. Lastly, we discuss the interventions available to reduce these biases.
