Explaining Adolescents’ Affect: A Time-Use Study of Opportunities for Support and Autonomy across Interpersonal Contexts

In order to uncover the reason why adolescents generally experience less positive emotional experience in the presence of parents, we compared the association of perceived opportunities for autonomy and support to adolescents’ positive emotional states when they were with their parents vs. in other interpersonal contexts. Thirty-one white, lower socioeconomic status, ninth grade students evaluated the fulfillment of their autonomy and support needs and their emotional experiences at multiple time points within a variety of interpersonal contexts over a one-week period. Hierarchical linear modeling of 1268 surveys showed that, compared to when they were with only their parents, these adolescents experienced relatively more frequent positive emotions when they were with peers, or with other adults in addition to or in the absence of their parents. Moreover, perceived opportunities for autonomy and support were associated with positive emotional experiences at a given time point. Perceived autonomy and support operated differently depending on the interpersonal context; the effects of these opportunities were smaller in the context of parent-only interactions than those involving interactions with other people. This study contributes to the literature on adolescent affect by showing that the moment-by-moment, intra-individual psychological affordances of autonomy and support are differentially associated with emotional experiences depending on the interpersonal context. Furthermore, these findings suggest that individuation-relatedness theory appears to be applicable to a relatively understudied population, namely white adolescents from low-SES families.     

When Parents Refuse: Resolving Entrenched Disagreements Between Parents and Clinicians in Situations of Uncertainty and Complexity

When shared decision making breaks down and parents and medical providers have developed entrenched and conflicting views, ethical frameworks are needed to find a way forward. This article reviews the evolution of thought about the best interest standard and then discusses the advantages of the harm principle (HP) and the zone of parental discretion (ZPD). Applying these frameworks to parental refusals in situations of complexity and uncertainty presents challenges that necessitate concrete substeps to analyze the big picture and identify key questions. I outline and defend a new decision-making tool that includes three parts: identifying the nature of the disagreement, checklists for key elements of the HP and ZPD, and a “think list” of specific questions designed to enhance use of the HP and ZPD in clinical decision making. These tools together will assist those embroiled in complex disagreements to disentangle the issues to find a path to resolution.     

Maternal positive parenting style is associated with better functioning in hyperactive/inattentive preschool children

Many preschoolers are highly inattentive, impulsive, and hyperactive; but only some are impaired in their functioning. Yet factors leading to functional impairment, above and beyond the severity of inattentive and hyperactive symptoms, have not been systematically examined. This study examined a model suggesting that after controlling for attention‐deficit/hyperactivity disorder (ADHD) symptom severity, child temperament is uniquely associated with parenting stress; that parenting stress affects parenting style, above and beyond child characteristics; that parenting style is related to the level of child impairment, above and beyond the effects of child symptoms, temperament, and parenting stress; and finally that parenting style moderates the relationship between ADHD symptom severity and child functioning. Child measures included parent‐ and teacher‐rated ADHD symptom severity, teacher‐rated temperament, and clinician‐rated functioning in a sample of 138 inattentive/hyperactive preschoolers. Maternal self‐ratings of parenting style and parenting stress were obtained. Analyses indicated that, after controlling for symptom severity, child temperament was related to maternal parenting stress, which was additionally related to both maternal parenting style and child functioning. Maternal positive parenting style moderated the relationship between ADHD symptom severity and child impairment, indicating that a positive parenting style plays a protective role in the functioning of hyperactive/inattentive preschoolers.

Emotion Regulation and the Quality of Social Interaction: Does the Ability to Evaluate Emotional Situations and Identify Effective Responses Matter?

We examined self and friends' ratings of social relationship quality and everyday social interactions in 3 studies involving 544 college students in Germany, Spain, and the United States. Scores on a situational judgment test measuring strategic emotion regulation ability (SERA) were negatively related to conflict with others. SERA was more consistently and strongly related to conflict with others than to the positive dimension of relationship quality (support, companionship, and nurturance). The relationship between SERA and conflict was generally not mediated by trait positive or negative affect, and it remained significant or marginally significant controlling for the Big Five personality traits. These findings highlight the importance of the ability to evaluate emotional situations and identify effective responses to these in interpersonal emotion regulation. Furthermore, they suggest that situational judgment and flexible response selection may help people to manage conflicts more than to bond with others.     

The locus of the benefits of repetition-lag memory training

The repetition-lag training procedure developed by Jennings and Jacoby (2003 , Neuropsychological Rehabilitation, 14, 417) has been shown to improve older adults' performance in the recognition memory task used for training, and to improve performance in a variety of other memory and executive function tasks ( Jennings, Webster, Kleykamp, & Dagenbach, 2005 , Aging, Neuropsychology, and Cognition, 12, 278). The present study examined the effects of concurrent interference tasks during the study or test phases of training to localize the source of gains. Overall, the results suggest that training is resilient and resistant to interference, but also that the processes used during the test phases of training are more important to the gains seen in the primary task and in the transfer tasks than those used in the study phases.     

Trace and contextual fear conditioning are impaired following unilateral microinjection of muscimol in the ventral hippocampus or amygdala, but not the medial prefrontal cortex

Trace fear conditioning, in which a brief empty "trace interval" occurs between presentation of the CS and UCS, differs from standard delay conditioning in that contributions from both the hippocampus and prelimbic medial prefrontal cortex (PL mPFC) are required to form a normal long term memory. Little is currently known about how the PL interacts with various temporal lobe structures to support learning across this temporal gap between stimuli. We temporarily inactivated PL along with either ventral hippocampus or amygdala in a disconnection design to determine if these structures functionally interact to acquire trace fear conditioning. Disconnection (contralateral injections) of the PL with either the ventral hippocampus or amygdala impaired trace fear conditioning; however, ipsilateral control rats were also impaired. Follow-up experiments examined the effects of unilateral inactivation of the PL, ventral hippocampus, or amygdala during conditioning. The results of this study demonstrate that unilateral inactivation of the ventral hippocampus or amygdala impairs memory, while bilateral inactivation of the PL is required to produce a deficit. Memory deficits after unilateral inactivation of the ventral hippocampus or amygdala prevent us from determining whether the mPFC functionally interacts with the medial temporal lobe using a disconnection approach. Nonetheless, our findings suggest that the trace fear network is more integrated than previously thought.     

Intra-amygdala infusion of the protein kinase Mzeta inhibitor ZIP disrupts foreground context fear memory

Protein kinase Mzeta has been the subject of much recent interest, as it is the only molecule currently identified to maintain memory. Despite the wealth of studies investigating PKMζ in memory, questions remain about which types of memory PKMζ supports. Further, it is unclear how long the inhibitor of PKMz, ζ-pseudosubstrate inhibitory peptide (ZIP) remains in the brain after infusion. Here, we demonstrate that foreground context fear memory requires PKMζ activity in the amygdala. We also show that ZIP is fully cleared from the brain by 24h after infusion. These data contribute to a growing body of literature that demonstrates that PKMζ plays a key role in maintaining amygdala-dependent memory and provides new information about the degradation timecourse of the most commonly used inhibitor of PKMζ, ZIP.     

Are head cues necessary for goats (Capra hircus) in recognising group members?

In this study, we investigated whether goats can distinguish a member of their own group from one belonging to a different group even when the head of the goat in question cannot be seen. In the experiment, a total of 45 adult female goats (walkers) were trained to walk along a passageway at the end of which they learnt to expect food (trial run). Walking down this corridor, they passed another adult female goat (stimulus goat) whose trunk and hind legs alone were visible. Using 19 individuals, ten pairs of stimulus goats consisting of one goat from the walker's group and one from a different group were matched in terms of body size, constitution, colour and coat length. In addition, the stimulus goat from the same group as the walker had to be higher ranking than the latter to avoid being attacked. The walkers completed two, four or six trial runs depending on the number of pairs suitable for a given walker. The walker's exploratory behaviour (observing and sniffing at the stimulus goat) was recorded. Data from 109 trial runs were analysed using generalised linear mixed-effects models with crossed random effects. On average, the walker spent a total of 8.7?s exploring the stimulus goat visually and olfactorily if the latter was from a different group and only about half as long (4.2?s) if it was from her own group. In particular, the time a walker spent observing a stimulus goat whilst approaching the latter was significantly longer if the stimulus goat belonged to a different group than to her own (2.5?s as opposed to 1.4?s). Moreover, a stimulus goat from a different group was sniffed at significantly longer (4.6?s) than one from the same group (1.9?s). Results suggest that goats can easily discriminate between members of their own group and those of a different group even when the latter's heads are hidden. Olfactory and visual cues are probably important for identifying group members.     

Comparing implementation intention interventions in relation to young adults’ intake of fruit and vegetables

This study tests whether the effectiveness of implementation intention-based interventions to increase fruit and vegetable intake in a young adult population can be enhanced using additional pre-intervention instructions and alternative formats; namely, an ‘if-then’ implementation intention versus a more general, ‘global’ plan that does not explicitly link a situational cue with a goal-directed response. Participants (N?=?557) completed pre-test measures of planning, motivation and behaviour with respect to increasing their fruit and vegetable intake before being randomised to a 3 (intervention format: control vs. ‘if-then’ vs. ‘global’ implementation intentions)?×?2 (pre-intervention instruction vs. no pre-intervention instruction) between-participants design. Results revealed a significant intervention format by time interaction, such that intake significantly increased by 0.50 portions in the if-then format condition compared with 0.31 in the global format and 0.01 in the control condition. These results suggest that ‘if-then’ manipulations are superior in promoting behaviour change in an applied setting. The use of pre-intervention instructions had no additional effect on behaviour, providing evidence for the efficacy of implementation intentions even when experimenter demand is reduced. Evidence is also presented to suggest that reported increases in intake are not related to demand characteristics.     

Dimensionality of the Beck Anxiety Inventory in a Polytrauma Sample of OEF/OIF/OND Veterans: Findings From Exploratory and Confirmatory Factor Analysis

The Beck Anxiety Inventory (BAI) is commonly used as a screening instrument for symptoms of anxiety in clinical settings. The factor structure has been researched in a variety of different clinical settings with results ranging from a 2- to 5-factor structure. The purpose of this study was to explore the factor structure of this instrument in a polytrauma veteran sample. A sample of 304 veterans was used for this study. All subjects were administered the BAI screening measure as part of an evaluation in an outpatient polytrauma clinic. Exploratory factor analysis was conducted for half of the sample, followed by confirmatory factor analysis for the remaining sample to determine the best model. Factor analyses revealed that a 5-factor model provided a best fit. It is interesting to note that previously identified models of the BAI with other types of samples did not provide the best fit for this polytrauma sample. The BAI may provide additional information for clinicians when examining the 5-factor model with veterans in polytrauma settings. The factor structure of the BAI includes 1 factor (i.e., personal safety) that may be unique for veterans who have served in combat zones.
