Psychological Androgyny and Children’s Mental Health: A New Look with New Measures

We evaluated Bem’s (1981, 1993) thesis that psychological androgyny—perceiving the self to possess characteristics of both genders—is associated with healthy adjustment and minimal gender-polarizing cognition. Prior studies testing Bem’s ideas have yielded ambiguous results, mainly because self-perceptions of gender-typed attributes have been inferred narrowly from self-perceptions of expressive and instrumental personality traits. We administered measures of gender identity (self-perceived similarity to a gender) that more clearly capture self-perceptions of attributes typical of a gender, and we examined conjoint influences of same-gender typicality and other-gender typicality on children’s self-esteem, internalizing problems, felt pressure for gender differentiation, and sexist ideology. Two studies were conducted with ethnically/racially diverse samples of preadolescent children in the southeastern United States. In Study 1 (N?=?305, M _age?=?10.8 years), androgynous children (i.e., children who saw themselves as similar to both genders) reported high self-esteem, evidenced few internalizing problems, and reported feeling little pressure for gender differentiation. In Study 2 (N?=?236, M _age?=?11.3 years), androgynous boys reported few sexist beliefs. Children with other patterns of gender identity (e.g., high same-gender typicality coupled with low other-gender typicality) sometimes showed similar correlates, but each other pattern of gender identity was associated with poor adjustment or strong gender-differentiating cognition on at least one dependent variable whereas androgyny never was. Results support Bem’s thesis that persons who perceive themselves as possessing characteristics of both genders enjoy mental health advantages over those who perceive themselves as possessing characteristics of only one.     

Identifying Beneficial Physical Activity During School Recess: Utility and Feasibility of the Fitbit

The purpose of the current study was to assess the utility, feasibility, and reliability of Fitbit accelerometers to measure physical activity (via steps) of 15 young children simultaneously during recess. Fitbit-recorded steps per minute (SPM) were used as the primary measure to assess levels of activity in children playing in various structured (i.e., instructed) and unstructured (i.e., free play) recess activities. The results suggested that the number of steps measured by two Fitbits resulted in high levels of agreement, and the Fitbits were successful at identifying differential levels of activity across multiple types of play activities. Across all children, running or walking was associated with the most SPM (M = 89) and highest percentage of moderate-to-vigorous physical activity (MVPA; M = 47%), followed by soccer (M = 58 SPM; M = 12% MVPA), free play (M = 53 SPM; 3% MVPA), and tag (M = 43 SPM; 7% MVPA). The utility of the Fitbit’s minute-by-minute data records was demonstrated, with the use of additional third-party software by Python, as differential levels of physical activity associated with various play behaviors were detected, and all 15 participants were assessed simultaneously with very few observers.     

Attention flexibly trades off across points in time

Sensory signals continuously enter the brain, raising the question of how perceptual systems handle this constant flow of input. Attention to an anticipated point in time can prioritize visual information at that time. However, how we voluntarily attend across time when there are successive task-relevant stimuli has been barely investigated. We developed a novel experimental protocol that allowed us to assess, for the first time, both the benefits and costs of voluntary temporal attention when perceiving a short sequence of two or three visual targets with predictable timing. We found that when humans directed attention to a cued point in time, their ability to perceive orientation was better at that time but also worse earlier and later. These perceptual tradeoffs across time are analogous to those found across space for spatial attention. We concluded that voluntary attention is limited, and selective, across time.     

No Ordinary Life: Complex Narratives of Trauma and Resilience in Under-Resourced Communities

This investigation examines the occurrence and impact of chronic adversity for young adults who grew up amidst poverty and community violence. Young adults in such contexts, particularly those who have been involved with the courts, are not commonly conceptualized through the developmental lens of complex trauma but rather described by maladaptive behaviors and risk to society. This grounded theory analysis explored how participants perceive and make meaning of their experiences. Interview data revealed consistent narratives of childhood neglect and psychological maltreatment, chronic loss, intergenerational trauma exposure, and the resulting survival-based adaptation. We identified 3 primary themes across the participant narratives: (a) lack of need fulfillment; paradoxical experience of self, others, and the world; and persistent sense of purpose and meaning. Findings illuminated the complexity of ongoing struggle, adaptation, and resilience in adult survivors. The need for an increased focus in trauma-informed treatment of adults in underresourced communities is discussed.     

Exploring the relationship between compressed work hours satisfaction and absenteeism in front-line service work

There has been an upsurge of interest in compressed workweek schedules because of the opportunities they provide for enhanced organizational efficiency and more balanced work and life roles for employees. This study tested a moderated mediation model of the effects of compressed work hours satisfaction on absenteeism with the purpose of exploring both the mediation effects of emotional exhaustion and physical health and the moderating effects of sex on this relationship. It utilized data drawn from a sample of 236 contact-centre service workers linked to absenteeism data collected for a period of 12 months following the survey. Results indicated that compressed work hours satisfaction was associated with lower absenteeism and that this relationship was mediated sequentially through emotional exhaustion and physical health. Although the indirect effect of compressed work hours satisfaction on absenteeism through emotional exhaustion and physical health was not significantly different between women and men, the relationship between compressed work hours satisfaction and physical health was positive for women but not for men. The implications of these findings are discussed.     

Quiet eye facilitates sensorimotor preprograming and online control of precision aiming in golf putting

An occlusion protocol was used to elucidate the respective roles of preprograming and online control during the quiet eye period of golf putting. Twenty-one novice golfers completed golf putts to 6-ft and 11-ft targets under full vision or with vision occluded on initiation of the backswing. Radial error (RE) was higher, and quiet eye was longer, when putting to the 11-ft versus 6-ft target, and in the occluded versus full vision condition. Quiet eye durations, as well as preprograming, online and dwell durations, were longer in low-RE compared to high-RE trials. The preprograming component of quiet eye was significantly longer in the occluded vision condition, whereas the online and dwell components were significantly longer in the full vision condition. These findings demonstrate an increase in preprograming when vision is occluded. However, this was not sufficient to overcome the need for online visual control during the quiet eye period. These findings suggest the quiet eye period is composed of preprograming and online control elements; however, online visual control of action is critical to performance.     

Attention problems and executive functions in children with spina bifida and hydrocephalus.

This study addressed the incidence of Attention-Deficit/Hyperactivity Disorder (ADHD) subtypes in children with spina bifida meningomyelocele and shunted hydrocephalus (SBH) as well as differences in executive functions among these subtypes. Parent rating scales revealed that 31% of the group with SBH could be identified with AD/HD, mostly the Inattentive type (23%). The group with SBH differed from normal controls on cognitive measures of executive functions, but subtype differences were not significant. Multivariate tests showed that children with SBH were rated with greater difficulties on the Behavior Rating Inventory of Executive Function (BRIEF) compared to controls; those with SBH and any subtype of ADHD differed from those with SBH and no ADHD; and those with ADHD (Combined Type) differed significantly from those with ADHD (Predominantly Inattentive Type). Subtype differences on univariate tests in the latter comparison were significant on the BRIEF Inhibit scale, showing more disinhibition in those with SBH and ADHD (Combined Type), but no significant differences were apparent on the BRIEF Sustain, Shift, and Initiate scales. The results show that the incidence of ADHD in children with SBH exceeds the population rate, is represented by problems with inattention rather than with impulsivity and hyperactivity; and that as with non-brain injured individuals, subtype differences in cognitive function remain to more clearly delineated.     

Distributed and massed practice: from laboratory to classroom

The benefit to memory of spacing presentations of material is well established but lacks an adequate explanation and is rarely applied in education. This paper presents three experiments that examined the spacing effect and its application to education. Experiment 1 demonstrated that spacing repeated presentations of items is equally beneficial to memory for a wide range of ages, contrary to some theories. Experiment 2 introduced ‘clustered’ presentations as a more relevant control than massed, reflecting the fact that massed presentation of material is uncommon in education. The scheduling of clustered presentations was intermediate between massed and distributed, yet recall was no different than for massed. Experiment 3, a classroom‐based study, demonstrated the benefit of distributed over clustered teaching of reading through modification of the scheduling of everyday lessons. Thus, the effectiveness of teaching may be improved by increasing the degree to which lessons are distributed. Copyright © 2004 John Wiley & Sons, Ltd.     

Nicotine trained as a negative feature passes the retardation-of-acquisition and summation tests of a conditioned inhibitor

Nicotine functions as a negative feature in a Pavlovian discriminated goal-tracking task. Whether withholding of responding to the conditional stimulus (CS) reflects nicotine functioning as a conditioned inhibitor is unknown. Accordingly, the present research sought to determine whether nicotine trained as a negative feature passed the retardation-of-acquisition and summation tests, thus characterizing it as a pharmacological (interoceptive) conditioned inhibitor. In the retardation test, rats received either nicotine (0.4 mg/kg) or chlordiazepoxide (5 mg/kg) negative feature training in which the drug state signaled when a 15-sec light CS would not be paired with sucrose; light was paired with sucrose on intermixed saline sessions. Following acquisition of the discrimination, both groups received nicotine CS training in which sucrose was intermittently available on nicotine but not intermixed saline sessions. Acquisition of conditioned responding to the nicotine CS was slower in the nicotine negative feature group than in the chlordiazepoxide negative feature group. In the summation test, rats were assigned to either the nicotine negative feature group or a pseudoconditioning control. In this control, the light CS was paired with sucrose on half the nicotine and half the saline sessions. Both groups also received excitatory training in which a white noise CS was paired with sucrose. The summation test consisted of presenting the white noise in conjunction with nicotine. Conditioned responding evoked by the white noise was decreased in the negative feature but not the pseudoconditioning group. Combined, the results provide the first evidence that an interoceptive stimulus (nicotine) can become a conditioned inhibitor.     

Constraints on infants' musical rhythm perception: effects of interval ratio complexity and enculturation

Effects of culture-specific experience on musical rhythm perception are evident by 12 months of age, but the role of culture-general rhythm processing constraints during early infancy has not been explored. Using a habituation procedure with 5- and 7-month-old infants, we investigated effects of temporal interval ratio complexity on discrimination of standard from novel musical patterns containing 200-ms disruptions. Infants were tested in three ratio conditions: simple (2:1), which is typical in Western music, complex (3:2), which is typical in other musical cultures, and highly complex (7:4), which is relatively rare in music throughout the world. Unlike adults and older infants, whose accuracy was predicted by familiarity, younger infants were influenced by ratio complexity, as shown by their successful discrimination in the simple and complex conditions but not in the highly complex condition. The findings suggest that ratio complexity constrains rhythm perception even prior to the acquisition of culture-specific biases.
