Social network composition and attitude strength: Exploring the dynamics within newly formed social networks

Recent evidence suggests that people who are embedded within attitudinally congruent social networks have stronger attitudes than those embedded in attitudinally diverse networks. The current research examines the causal processes responsible for this relation. Two studies capitalized on naturally occurring experiments whereby college students are quasi-randomly assigned to social contexts containing varying levels of attitudinal diversity. Replicating past research, individuals in attitudinally diverse social networks exhibited less resistance to attitude change and less attitude stability than those in more attitudinally congruent networks. Although there was evidence of attitude projection and selective network construction, neither of these processes could account for the relation between social network composition and attitude strength. These findings corroborate and extend previous results, reinforcing the notion that the social context in which people are embedded has important implications for the durability of their attitudes.     

Two Steps Forward,One Step Back: The Presence of Female Characters and Gender Stereotyping in Award-Winning Picture Books Between the 1930s and the 1960s

Since the late 1960s, there has been steady, progressive change in the depiction of gender in award-winning picture books for children (e.g., Clark, Almeida, Gurka, & Middleton, 2003). Female characters in Caldecott winners and runners-up have become increasingly visible and gender stereotyping has become decreasingly evident. In this article we consider whether this steady change can be projected back into the decades before the 1960s, or whether local, temporal variation in gender norms affected less monotonic change. We found that Caldecotts of the late 1940s and the late 1960s had fewer visible female characters than Caldecotts of the late 1930s and the late 1950s, but that characters in the 1940s and 1960s were less gender stereotyped than the characters of the 1930s and 1950s. We interpret these findings in terms of the greater level of conflict over gender roles that existed in the 1940s and 1960s, as well as the relatively greater status enjoyed by American women in those decades.     

Modeling the Role of Child Ethnicity and Gender in Children's Differential Response to Teacher Expectations1

This study examined the relationship between fall teacher expectations and year‐end achievement among 561 children in 1st, 3rd, and 5th grades. Specifically, we hypothesized that children from academically stigmatized groups (African Americans generally and girls in mathematics) are more likely to be responsive to negative teacher expectancies than are children from nonstigmatized groups. Controlling for prior achievement and class membership, moderator effects were tested with hierarchical linear models in the whole sample and with loglinear models in a subsample of children who were targets of extreme teacher over‐ and underestimates of ability. Among targets of extreme teacher over‐ and underestimates, in 3rd and 5th grade, ethnicity moderated expectancy effects in reading; and in 5th grade, gender moderated expectancy effects in math but not reading. Members of stigmatized groups were more susceptible to teacher underestimates of ability. Implications are discussed in terms of differential response to teacher expectations and in terms of how susceptibility to teacher expectations is conceptualized and inferred.

Market mavenism and consumer self‐confidence

• The purpose of this study was to test hypothesized associations between market mavenism and consumer self‐confidence (CSC). A survey of 190 US consumers provided the data. The results showed significant relationships between mavenism and several dimensions of CSC, and regression analysis emphasized the relationships with two of these: information acquisition (confidence in the ability to obtain and use marketplace information) and social outcomes decision making (confidence in obtaining positive reactions from others). These findings both enrich our knowledge of the psychology of market mavenism by suggesting some motivations for these behaviors and suggest marketing strategies can be fine‐tuned to appeal more effectively to this important segment of consumers.

Visuomotor tracking abilities of speakers with apraxia of speech or conduction aphasia

This investigation examined the visuomotor tracking abilities of persons with apraxia of speech (AOS) or conduction aphasia (CA). In addition, tracking performance was correlated with perceptual judgments of speech accuracy. Five individuals with AOS and four with CA served as participants, as well as an equal number of healthy controls matched by age and gender. Participants tracked predictable (sinusoidal) and unpredictable signals using jaw and lip movements transduced with strain gauges. Tracking performance in participants with AOS was poorest for predictable signals, with decreased kinematic measures of cross-correlation and gain ratio and increased target-tracker difference. In contrast, tracking of the unpredictable signal by participants with AOS was performed as well as for other groups (e.g. participants with CA, healthy controls). Performance of the subjects with AOS on the predictable tracking task was found to strongly correlate with perceptual judgments of speech. These findings suggest that motor control capabilities are impaired in AOS, but not in CA. Results suggest that AOS has its basis in motor programming deficits, not impaired motor execution.     

Multi-limb coordination and rhythmic variability under varying sensory availability conditions in children with DCD

Children with Developmental Coordination Disorder (DCD) have sensory processing deficits; how do these influence the interface between sensory input and motor performance? Previously, we found that children with DCD were less able to organize and maintain a gross motor coordination task in time to an auditory cue, particularly at higher frequencies [Whitall, J., Getchell, N., McMenamin, S., Horn, C., Wilms-Floet, A., & Clark, J. (2006). Perception-action coupling in children with and without DCD: Frequency locking between task relevant auditory signals and motor responses in a dual motor task. Child: Care, Health, and Development, 32, 679-692]. In the present study, we examine the same task (clapping in-phase to marching on a platform) under conditions involving the removal of vision and hearing. Eleven children with DCD (mean=7.21, SD=0.52 years), 7 typically developing (TD) children (mean=6.95+/-0.72 years), and 10 adults performed continuous clapping while marching under four conditions: with vision and hearing, without vision, without hearing, and without both. Results showed no significant condition effects for any measure taken. The DCD group was more variable in phasing their claps and footfalls than both the adult group and the TD group. There were also significant group effects for inter-clap interval coefficient of variation and inter-footfall interval coefficient of variation, with the DCD group being the most variable for both measures. Coherence analysis between limb combinations (e.g., left arm-right arm, right arm-left leg) revealed that the adults exhibited significantly greater coherence for each combination than both of the children's groups. The TD group showed significantly greater coherence than the DCD group for every limb combination except foot-foot and left hand-right foot. Measures of approximate entropy indicated that adults differed from children both with and without DCD in the structure of the variability across a trial with adults showing more complexity. Children with DCD are able to accomplish a self-initiated gross-motor coordination task but with increased variability for most but not all measures compared to typically developing children. The availability of visual and/or auditory information does not play a significant role in stabilizing temporal coordination of this task, suggesting that these are not salient sources of information for this particular task.     

Structures of Personality and Their Relevance to Psychopathology: II. Further Articulation of a Comprehensive Unified Trait Structure

ABSTRACT There is increasing agreement that the current categorical system of personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV; American Psychiatric Association, 2000) should be replaced by a trait dimensional scheme in DSM‐V. In particular, the consensus appears to be converging on a hierarchical Big Four model. The broad factors that form the apex of this hierarchy are essentially maladaptive variants of the Big Five traits of normal personality, minus Openness. We argue that this Big Four model is incomplete, however, in that it fails to model characteristics related to the “odd or eccentric” Cluster A PDs adequately. We report the results of three studies that examine these odd, eccentric characteristics in relation to basic dimensions of normal and abnormal personality. The results of these studies establish the existence of an Oddity factor that is (a) broader than the Cluster A traits and (b) distinct from Openness and the other Big Five dimensions. Consequently, its addition yields an alternative five‐factor model of personality pathology (considering only abnormal traits) and an expanded, integrated Big Six taxonomy that subsumes both normal and abnormal personality characteristics.     

Continuous and discontinuous drawing: high temporal variability exists only in discontinuous circling in young children

The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.
