Older,wiser, and happier? Comparing older adults’ and college students’ self-defining memories

The present study compared self-defining memories in adults 50 years of age and older to the self-defining memories of college students. Findings are largely congruent with previous memory and ageing research, but shed additional light on how personal memories are employed to achieve a sense of identity and continuity in older adults. Older adults’ self-defining memories, compared to those of younger adults, were more positive in emotional tone, more summarised and less detailed, and more likely to contain integrative meaning. The implications of these findings for assessing normative personal memory in older adults are discussed along with more general observations about narrative identity in older adulthood.     

PARENT EDUCATION INTERVENTION RESULTS IN DECREASED CHALLENGING BEHAVIOR AND IMPROVED TASK ENGAGEMENT FOR STUDENTS WITH DISABILITIES DURING ACADEMIC TASKS

Children with developmental disabilities and attention deficit hyperactivity disorder often engage in challenging behavior when presented with academic demands. Parents of school‐age children with such diagnoses are commonly asked to assist their child with academic tasks but may struggle to do so as a result of challenging behavior. This study evaluated the effects of a parent education intervention on the challenging behaviors and task engagement of three school‐age children with disabilities during academic activities. Parent education consisted of (i) weekly didactic instruction; (ii) modeling; (iii) role‐play; and (iv) in vivo coaching and performance feedback. Using a non‐concurrent multiple baseline across participants with embedded individual multi‐element design, this study demonstrates that a parent education intervention results in decreases in challenging behavior and increases in task engagement. These results suggest that parent education focused on addressing challenging behavior during one‐to‐one instruction may facilitate completion of academic tasks. Implications for practice and suggestions for future research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Prospective Risk Factors for Adolescent PTSD: Sources of Differential Exposure and Differential Vulnerability

There are two types of risk factors for developing PTSD: factors that increase the likelihood of experiencing a potentially traumatizing event and factors that increase the likelihood of developing symptoms following such events. Using prospective data over a two-year period from a large, diverse sample of urban adolescents (n?=?1242, Mean age?=?13.5), the current study differentiates these two sources of risk for developing PTSD in response to violence exposure. Five domains of potential risk and protective factors were examined: community context (e.g., neighborhood poverty), family risk (e.g., family conflict), behavioral maladjustment (e.g., internalizing symptoms), cognitive vulnerabilities (e.g., low IQ), and interpersonal problems (e.g., low social support). Time 1 interpersonal violence history, externalizing behaviors, and association with deviant peers were the best predictors of subsequent violence, but did not further increase the likelihood of PTSD in response to violence. Race/ethnicity, thought disorder symptoms, and social problems were distinctly predictive of the development of PTSD following violence exposure. Among youth exposed to violence, Time 1 risk factors did not predict specific event features associated with elevated PTSD rates (e.g., parent as perpetrator), nor did interactions between Time 1 factors and event features add significantly to the prediction of PTSD diagnosis. Findings highlight areas for refinement in adolescent PTSD symptom measures and conceptualization, and provide direction for more targeted prevention and intervention efforts.     

Discrimination of acoustically similar conspecific and heterospecific vocalizations by black-capped chickadees (<Emphasis Type="Italic">Poecile atricapillus</Emphasis>)

Chickadees produce a multi-note chick-a-dee call in multiple socially relevant contexts. One component of this call is the D note, which is a low-frequency and acoustically complex note with a harmonic-like structure. In the current study, we tested black-capped chickadees on a between-category operant discrimination task using vocalizations with acoustic structures similar to black-capped chickadee D notes, but produced by various songbird species, in order to examine the role that phylogenetic distance plays in acoustic perception of vocal signals. We assessed the extent to which discrimination performance was influenced by the phylogenetic relatedness among the species producing the vocalizations and by the phylogenetic relatedness between the subjects’ species (black-capped chickadees) and the vocalizers’ species. We also conducted a bioacoustic analysis and discriminant function analysis in order to examine the acoustic similarities among the discrimination stimuli. A previous study has shown that neural activation in black-capped chickadee auditory and perceptual brain regions is similar following the presentation of these vocalization categories. However, we found that chickadees had difficulty discriminating between forward and reversed black-capped chickadee D notes, a result that directly corresponded to the bioacoustic analysis indicating that these stimulus categories were acoustically similar. In addition, our results suggest that the discrimination between vocalizations produced by two parid species (chestnut-backed chickadees and tufted titmice) is perceptually difficult for black-capped chickadees, a finding that is likely in part because these vocalizations contain acoustic similarities. Overall, our results provide evidence that black-capped chickadees’ perceptual abilities are influenced by both phylogenetic relatedness and acoustic structure.     

Observed Attachment and Self-Report Affect Within Romantic Relationships

Adult attachment provides unique insights that help researchers and clinicians understand the complexities of individuals and relationships. In romantic relationships, individual attachment can explain partners' abilities for closeness and autonomy as well as how they experience affect within the relationship. These affective experiences during couple interactions have been shown to influence both proximal and distal relationship outcomes. Thus, the authors explore the impact of partners' observed attachment behaviors—coded using the AABQ—on continuous reports of their affective experiences during both difficult and positive marital conversations. Variables examining couple affective negativity and flexibility were developed using state space grids, and data were analyzed using GridWare. Results showed that observed female attachment behaviors significantly impacted a couple's affective experiences of negativity and flexibility during conversations, while there were no significant associations between male observed attachment behaviors and the couple affective experience. Clinical implications and suggestions for future research are discussed.     

Examining School Attachment,Social Support,and Trauma Symptomatology Among Court-Involved,Female Students

Court-involved youth (i.e., youth in the foster care and/or juvenile justice systems), and particularly those in residential placement facilities, often present with trauma histories that can impede various areas of development and functioning. These traumatic histories can negatively impact academic performance and school success, leading to poorer outcomes later in life. In particular, female youth in these systems exhibit unique responses to traumatic experiences that further complicate healthy development. This study assesses female, court-involved students (n?=?141), exploring the relationship between school attachment and school involvement, school social support (from peers, teachers, and other staff), and trauma symptomatology among a sample of residential placement students exposed to a trauma-informed teaching intervention over the course of a school year. It was hypothesized that higher school attachment/involvement and social support would be associated with lower student trauma symptomatology. As expected, findings demonstrated that students in the sample had experienced high trauma exposure, as indicated by their high trauma symptomatology. Unexpectedly, they also had high school attachment. Furthermore, higher school attachment was associated with lower trauma symptoms among students. On the other hand, students reported lower levels of social support from classmates, which was associated with significantly higher trauma symptomatology. Implications for future research are addressed.     

Top-down knowledge modulates onset capture in a feedforward manner

How do we select behaviourally important information from cluttered visual environments? Previous research has shown that both top-down, goal-driven factors and bottom-up, stimulus-driven factors determine which stimuli are selected. However, it is still debated when top-down processes modulate visual selection. According to a feedforward account, top-down processes modulate visual processing even before the appearance of any stimuli, whereas others claim that top-down processes modulate visual selection only at a late stage, via feedback processing. In line with such a dual stage account, some studies found that eye movements to an irrelevant onset distractor are not modulated by its similarity to the target stimulus, especially when eye movements are launched early (within 150-ms post stimulus onset). However, in these studies the target transiently changed colour due to a colour after-effect that occurred during premasking, and the time course analyses were incomplete. The present study tested the feedforward account against the dual stage account in two eye tracking experiments, with and without colour after-effects (Exp. 1), as well when the target colour varied randomly and observers were informed of the target colour with a word cue (Exp. 2). The results showed that top-down processes modulated the earliest eye movements to the onset distractors (<150-ms latencies), without incurring any costs for selection of target matching distractors. These results unambiguously support a feedforward account of top-down modulation.     

Cascading effects: the influence of attention bias to threat on the interpretation of ambiguous information

Both attention bias to threat and negative interpretive bias have been implicated in the emergence and maintenance of anxiety disorders. However, relations between attention and interpretive biases remain poorly understood. The current study experimentally manipulated attention bias to threat and examined the effects of attention training on the way ambiguous information was interpreted. Results suggest that the preferential allocation of attention towards threat affects the manner in which ambiguous information is interpreted. Individuals trained to attend to threat were more likely than individuals in a placebo training group to interpret ambiguous information in a threat-related manner. These data suggest that perturbations in the initial stages of information processing associated with anxiety may lead to a cascade of subsequent processing biases.     

Accuracy, confidence, and calibration: how young children and adults assess credibility

Do children and adults use the same cues to judge whether someone is a reliable source of information? In 4 experiments, we investigated whether children (ages 5 and 6) and adults used information regarding accuracy, confidence, and calibration (i.e., how well an informant's confidence predicts the likelihood of being correct) to judge informants' credibility. We found that both children and adults used information about confidence and accuracy to judge credibility; however, only adults used information about informants' calibration. Adults discredited informants who exhibited poor calibration, but children did not. Requiring adult participants to complete a secondary task while evaluating informants' credibility impaired their ability to make use of calibration information. Thus, children and adults may differ in how they infer credibility because of the cognitive demands of using calibration.     

Categorical perception of emotional facial expressions in preschoolers

Adults perceive emotional facial expressions categorically. In this study, we explored categorical perception in 3.5-year-olds by creating a morphed continuum of emotional faces and tested preschoolers’ discrimination and identification of them. In the discrimination task, participants indicated whether two examples from the continuum “felt the same” or “felt different.” In the identification task, images were presented individually and participants were asked to label the emotion displayed on the face (e.g., “Does she look happy or sad?”). Results suggest that 3.5-year-olds have the same category boundary as adults. They were more likely to report that the image pairs felt “different” at the image pair that crossed the category boundary. These results suggest that 3.5-year-olds perceive happy and sad emotional facial expressions categorically as adults do. Categorizing emotional expressions is advantageous for children if it allows them to use social information faster and more efficiently.
