When do women respond against discrimination? Exploring factors of subtlety,form, and focus

We examined the personal‐group discrimination discrepancy (PGDD), the tendency for women to recognize that others encounter sexism while simultaneously minimizing their own personal experiences with sexism, and the degree to which it (a) applies to all manifestations of discrimination, and (b) extends beyond perceptions of discrimination to taking action against it. Our findings replicated the PGDD when it comes to perceptions of discrimination, but this effect was reversed for behavioral action such that women were more likely to take action against discrimination when it was directed at them personally. We also disentangled the factors of subtlety (subtle vs. overt) and form (formal vs. interpersonal) by showing that women can reliably distinguish between these factors when determining their reactions to discrimination.     

Evidence for altered Fragile-X mental retardation protein expression in response to behavioral stimulation

The Fragile-X mental retardation protein, the protein absent in Fragile-X syndrome, is synthesized near synapses upon neurotransmitter activation. Humans and mice lacking this protein exhibit abnormal dendritic spine lengths and numbers. Here we investigated Fragile-X protein levels in animals exposed to behavioral paradigms that induce neuronal morphological change. Fragile-X protein immunoreactivity was examined in visual cortices of rats reared in a complex environment for 10 or 20 days, motor cortices of rats trained on motor-skill tasks for 3 or 7 days, and either visual or motor cortices of inactive controls. Rats exposed to a complex environment for 20 days or trained for 7 days on motor-skill tasks exhibited increased Fragile-X protein immunoreactivity in visual or motor cortices, respectively. These results provide the first evidence for a behaviorally induced alteration of Fragile-X protein expression and are compatible with previous findings suggesting synaptic regulation of its expression. These results also strengthen the association of Fragile-X mental retardation protein expression with the alteration of synaptic structure.     

Fragile X mental retardation protein levels increase following complex environment exposure in rat brain regions undergoing active synaptogenesis

Fragile X mental retardation protein (FMRP), which is absent in fragile X syndrome, is synthesized in vitro in response to neurotransmitter activation. Humans and mice lacking FMRP exhibit abnormal dendritic spine development, suggesting that this protein plays an important role in synaptic plasticity. Previously, our laboratory demonstrated increased FMRP immunoreactivity in visual cortex of rats exposed to complex environments (EC) and in motor cortex of rats trained on motor-skill tasks compared with animals reared individually in standard laboratory housing (IC). Here, we use immunohistochemistry to extend those findings by investigating FMRP levels in visual cortex and hippocampal dentate gyrus of animals exposed to EC or IC. Rats exposed to EC for 20 days exhibited increased FMRP immunoreactivity in visual cortex compared with animals housed in standard laboratory caging. In the dentate gyrus, animals exposed to EC for 20 days had higher FMRP levels than animals exposed to EC for 5 or 10 days. In light of possible antibody crossreactivity with closely related proteins FXR1P and FXR2P, FMRP immunoreactivity in the posterior-dorsal one-third of cerebral cortex was also examined by Western blotting following 20 days of EC exposure. FMRP levels were greater in EC animals, whereas levels of FXR1P and FXR2P were unaffected by experience. These results provide further evidence for behaviorally induced alteration of FMRP expression in contrast to its homologues, extend previous findings suggesting regulation of its expression by synaptic activity, and support the theories associating FMRP expression with alteration of synaptic structure both in development and later in the life-cycle.     

The developmental course of processing speed in children with and without learning disabilities

This study contrasted the development of processing speed in children with and without learning disabilities. We examined whether the same global mechanism presumed to be responsible for the normal developmental improvement in processing speed might also be associated with the processing speed deficiencies observed in children with learning impairments. One hundred and twenty-two children with learning disabilities in reading and/or math and 206 non-disabled community controls participated. There were no differences in relation of age to the development of processing speed for children with and without learning disabilities. We interpreted these results as suggesting that the underlying etiologies for the normal developmental change in processing speed and for the relative deficiencies in processing speed seen among children with learning disabilities were different.     

Does my daughter like math? Relations between parent and child math attitudes and beliefs

As early as age six, girls report higher math anxiety than boys, and children of both genders begin to endorse the stereotype that males are better at math than females. However, very few studies have examined the emergence of math attitudes in childhood, or the role parents may play in their transmission. The present study is the first to investigate the concordance of multiple implicit and explicit math attitudes and beliefs between 6- and 10-year-old children and their parents. Data from implicit association tasks (IATs) reveal that both parents and their children have implicit associations between math and difficulty, but only parents significantly associated math with males. Notably, males (fathers and sons) were more likely than females (mothers and daughters) to identify as someone who likes math (instead of reading), suggesting gender differences in academic preferences emerge early and remain consistent throughout adulthood. Critically, we provide the first evidence that both mothers’ and fathers’ attitudes about math relate to a range of math attitudes and beliefs held by their children, particularly their daughters. Results suggest that girls may be especially sensitive to parental math attitudes and beliefs. Together, data indicate that children entering formal school already show some negative math attitudes and beliefs and that parents’ math attitudes may have a disproportionate impact on young girls.     

The discourse of being ‘triggered’: Uses and meanings among counselling students

Despite the initial understanding of the word ‘triggered’ as relating to the clinical phenomenon of post-traumatic stress disorder (PTSD), this language has become a common part of the vernacular today, used by many people to apply to a wide variety of experiences and events. Counselling students are particularly sensitised to trauma, as well as identity politics, and are familiar with trigger warnings at college. They themselves have experienced trauma at high rates. Therefore, we were interested to understand how they might be using the word and interpreting the experience of being ‘triggered’, whether different sources of being triggered are related to emotional reactions, and whether a discourse analysis might indicate how and why the term has become useful and for what other experiences it might be serving as a stand-in. In this mixed-methods study, 79 counselling students from around the country shared their definitions and experiences of being ‘triggered’. Participants completed surveys and wrote narratives, which, via thematic qualitative analysis, were coded into five themes. The quantitative analysis focused on the relationship of feelings to themes and the relationship between anger suppression and coping with each theme. Discourse analysis explored how individuals wrote about responsibility and anger. It was discovered that those who wrote about being triggered from a past sexual assault did not discuss anger, nor the responsibility of others to protect them (as those who wrote about microaggressions did), but positioned themselves as overreactors. Results are discussed with regard to training and practice.     

Processing speed in children with attention deficit/hyperactivity disorder, inattentive type.

Attention Deficit/Hyperactivity Disorder (ADHD) is among the most common and most often reconceptualized neurobehavioral disorders of childhood. In the most recent DSM-IV, a primarily inattentive subtype of ADHD (AD) has again been identified. This study explores the neuropsychological profile of this group of children. Eighty-two children referred for school-related problems participated. Twenty-five met criteria for AD; 52 met criteria for reading disability (RD); 9 were comorbid for RD and AD. AD children performed poorly on measures of information processing speed. Children with comorbid AD/RD were distinguishable from those with RD on speed of processing measures only. Vulnerability to information processing load may be at the root of many of the behavioral manifestations of AD.     

Establishing arbitrary comparative relations and referential transformations of stimulus function in individuals with autism

Relational Frame Theory posits that complex language develops through arbitrarily applicable relational networks, with potential implications for individuals with autism. Responding relationally based on comparison occurs when participants respond to any number of comparative properties, such as “bigger” or “faster.” Experiment 1 established two 3-member comparative networks, in which a stimulus A was conditioned as “bigger” or “faster” than a stimulus B, and the stimulus B was conditioned as “bigger” or “faster” than a stimulus C in 2 children with autism. Both participants met the mastery criterion for the trained relations and demonstrated the emergence of the untrained combinatorially entailed A–C and C–A relations. The participants could also match the arbitrary A stimuli with larger or faster objects and the C stimuli with smaller or slower objects. The results were replicated in Experiment 2 with the same participants, where a 5-member relational network was established for the bigger/smaller relation.
