Categorising intersectional targets: An “either/and” approach to race- and gender-emotion congruity

Research on the interaction of emotional expressions with social category cues in face processing has focused on whether specific emotions are associated with single-category identities, thus overlooking the influence of intersectional identities. Instead, we examined how quickly people categorise intersectional targets by their race, gender, or emotional expression. In Experiment 1, participants categorised Black and White faces displaying angry, happy, or neutral expressions by either race or gender. Emotion influenced responses to men versus women only when gender was made salient by the task. Similarly, emotion influenced responses to Black versus White targets only when participants categorised by race. In Experiment 2, participants categorised faces by emotion so that neither category was more salient. As predicted, responses to Black women differed from those to both Black men and White women. Thus, examining race and gender separately is insufficient to understanding how emotion and social category cues are processed.     

First and Fourth Grade Boys' and Girls' Preferences For and Perceptions About Narrative and Expository Text

This investigation focused on elementary-aged (first and fourth grade) children's individual preferences for narrative and expository text and perceptions of what their same-aged peers would like to read. Preferences and perceptions of text were examined through the lenses of social constructivist and engaged reading theories. The overall purpose of this study was to examine elementary students' preferences for and perceptions about narrative and expository text. This study was a systematic replication and extension of Chapman, Filipenko, McTavish, and Shapiro's (2007) research in British Columbia with first graders. Two individually administered book preference (Open and Closed) tasks and interviews were administered to 84 students. Findings revealed gender and grade level profiles in terms of preferences, perceptions, and rationales for their book choices. As expected, both first and fourth grade boys demonstrated a strong preference for expository text, however, the fourth grade boys also showed a growing preference for narrative text as well. In contrast, both first and fourth grade girls demonstrated a strong preference for both narrative and expository text. For both boys and girls, book topic and pictures/illustrations were the two top categories that drew the children's interest and resulted in the most conversations. Results are discussed in light of implications for instruction, assessment, and future research.     

Measuring Parenting in Community and Public Health Research Using Brief Child and Parent Reports

The use of multi-method, multi-informant assessment is a hallmark of research in child development and mental health; however, many research strategies such as population surveys require brief assessment tools. The Alabama Parenting Questionnaire (APQ) is a popular measure of empirically identified aspects of positive and negative parenting styles important to conduct problems in children. A brief version exists, however it does not measure all relevant parenting domains, and it has not been validated for child reports. We evaluated validity of the brief parent and child report version of the complete five subscale version of the APQ in a sample of 208 children aged between 9 and 17, at risk for conduct problems and antisocial behaviour. The results showed that all five dimensions of parenting can be measured using a brief 15 item version; specifically child and parent reports converged as expected and discriminated high from low conduct problem children using parent and teacher reports. Only child reports converged with independent observations of parenting behaviour, supporting previous research showing that child reports of parenting are particularly important. Finally, results did not support the typical methods used for combining child and parent reports into one index.     

Block of glucocorticoid synthesis during re-activation inhibits extinction of an established fear memory

BackgroundThe pharmacology of traumatic memory extinction has not been fully characterized despite its potential as a therapeutic target for established, acquired anxiety disorders, including post-traumatic stress disorder (PTSD). Here we examine the role of endogenous glucocorticoids in traumatic memory extinction.MethodsMale C57BL/6J mice were injected with corticosterone (10 mg/kg, i.p.) or metyrapone (50 mg/kg, s.c.) during re-activation of a contextual fear memory, and compared to vehicle groups (N = 10–12 per group). To ensure that metyrapone was blocking corticosterone synthesis, we measured corticosterone levels following re-activation of a fear memory in metyrapone- and vehicle-treated animals.ResultsCorticosterone administration following extinction trials caused a long-lasting inhibition of the original fear memory trace. In contrast, blockade of corticosteroid synthesis with metyrapone prior to extinction trials enhanced retrieval and prevented extinction of context-dependent fear responses in mice. Further behavioral analysis suggested that the metyrapone enhancement of retrieval and prevention of extinction were not due to non-specific alterations in locomotor or anxiety-like behavior. In addition, the inhibition of extinction by metyrapone was rescued by exogenous administration of corticosterone following extinction trials. Finally, we confirmed that the rise in corticosterone during re-activation of a contextual fear memory was blocked by metyrapone.ConclusionsWe demonstrate that extinction of a classical contextual fear memory is dependent on endogenous glucocorticoid synthesis during re-activation of a fear memory. Our data suggest that decreased glucocorticoids during fear memory re-activation may contribute to the inability to extinguish a fear memory, thus contributing to one of the core symptoms of PTSD.     

Intentional self-regulation, ecological assets, and thriving in adolescence: a developmental systems model

The positive youth development (PYD) perspective emphasizes that thriving occurs when individual ?context relations involve the alignment of adolescent strengths with the resources in their contexts. The authors propose that a key component of this relational process is the strength that youth possess in the form of self-regulatory processes; these processes optimize opportunities to obtain ecological resources that enhance the probability of PYD. They use the selection, optimization, and compensation (SOC) model of intentional self-regulation to discuss the role of self-regulation in the PYD perspective among diverse youth.     

What Matters for Well-Being: Individual Perceptions of Quality of Life Before and After Important Life Events

In recent decades, what matters for individual quality of life (QoL) has increasingly been the focus of empirical social science research. However, individuals are rarely asked directly what is important for their quality of life as part of large-scale surveys. The present analysis studies perceptions of what matters for QoL in a large-scale longitudinal dataset—the British Household Panel Survey—which includes an open-ended question on QoL in three waves spanning ten years. We find that concepts of QoL change over the life course and differ between men and women. We hypothesize that changes in perceptions of QoL are related to important life events, such as the birth of a first child and retirement. These life events constitute ’turning points’ after which individuals often shift their priorities of what matters for their QoL. We further explore whether such shifts in priorities are stable or disappear more than five years after the life event.     

A Pilot Study of Psychotherapist Trainees' Alpha-Amylase and Cortisol Levels During Treatment of Recently Suicidal Clients With Borderline Traits

Psychotherapists often experience stress while providing psychotherapy, in particular when working with difficult presentations such as suicidality. As part of a larger study on the treatment of recently suicidal college students with borderline traits, 6 therapists in training collected their own salivary samples for alpha-amylase (AA) and cortisol (C) analyses immediately before and after sessions with 2 selected clients. On average, samples were collected for the same therapist-patient dyad throughout the year-long study to ensure that data reflected therapist responses across stages of treatment. Therapists also completed a working alliance questionnaire and rated perceived session difficulty immediately after each selected session. Contrary to expectations, therapists demonstrated elevated levels of stress as measured by AA and C at presession relative to postsession levels. Greater session difficulty was related to more pronounced declines in AA, whereas a stronger working alliance was linked to more pronounced reductions in C. Results suggest that physiological stress responses while working with recently suicidal clients with borderline traits occur primarily in terms of session anticipatory anxiety, whereas AA and C changes may be affected differently by factors such as session difficulty and working alliance. This is a pilot study, limited by its sample size, but the design, findings, and inclusion of physiological measures present an initial step in an essential line of research.

Neural enhancement and pre-emptive perception: the genesis of attention and the attentional maintenance of the cortical salience map

One of the stable hypotheses in systems neuroscience is the relationship between attention and the enhancement of visual responses when an animal attends to the stimulus in its receptive field (Goldberg and Wurtz, 1972 Journal of Neurophysiology 35 560-574). This was first discovered in the superior colliculus of the monkey: neurons in the superficial layers of the superior colliculus responded more intensely to the onset of a stimulus during blocks of trials in which the monkey had to make a saccade to it than they did during blocks of trials in which the monkey had to continue fixating a central point and not respond to the stimulus. This enhancement has been found in many brain regions, including prefrontal cortex (Boch and Goldberg, 1987 Investigative Ophthalmology 28 Supplement, 124), V4 (Moran and Desimone, 1985 Science 229 782-784), and lateral intraparietal area (Colby et al, 1996 Journal of Neurophysiology 76 2841-2852; Colby and Goldberg, 1999 Annual Review of Neuroscience 22 319-349), and even V1 (Lamme et al, 2000 Vision Research 40 1507-1521). In these studies the assumption has been that the monkey attended to the stimulus because the stimulus evoked an enhanced response. In the experiments described here we show that for abruptly appearing stimuli, attention is not related to the initial response evoked by the stimulus, but by the activity present on the salience map in the parietal cortex when the stimulus appears. Attention to the stimulus may subsequently, by a top down signal, sustain the map, but stimuli can as easily be suppressed by top down features as they can be enhanced.
