Happy thoughts: Enhancing well-being in the classroom with a positive events diary

Positive psychology interventions (PPIs) are effective in increasing well-being across the population. Whilst educators are recognising the importance of well-being in the classroom and of its long-term impact on life trajectory, the transformative potential of PPIs in educational settings is yet to be fully realised. This study investigates, for the first time, the effects of a PPI in school children by means of a daily dairy. Self-report questionnaires were used to measure well-being in school children aged 8–11 years. Across two studies, children kept a positive events diary, recording three experiences every day for a week. The intervention led to an increase in happiness and a decrease in depressive symptoms immediately following the intervention and at a three-month follow-up. Children who had unhappier baseline scores benefitted more from the intervention. This study demonstrates significant scope, in school settings, for targeted light-touch interventions to promote well-being in those with the greatest need.     

“Feeling my Sister’s Pain”: Perceived Victim Suffering Moderates the Impact of Sexualized Music Videos on Fijian Women’s Responses to Men’s Intimate Partner Violence against Women

To better understand how sexualized music videos affect women’s responses to intimate partner violence (IPV), we examined the role of individual variability in perceived victim pain and perceived victim culpability in moderating and mediating (respectively) the priming effects of sexual music videos on women. Female Fijian college students (n?=?243) were randomly assigned to one of three viewing conditions: stereotyped sexual music videos, non-stereotyped/non-sexual music videos, or neutral videos. All participants then read a portrayal of a male-toward-female IPV episode and their perceptions of the female victim and male perpetrator were assessed. Only women who minimized the victim’s pain were adversely affected by exposure to the stereotyped sexual videos. Specifically, for women who perceived low victim pain, those in the stereotyped video condition perceived the victim as more culpable and reported greater perpetrator-directed favorable responding than those in the other two conditions. For these women who perceived low victim pain, perceptions of victim culpability mediated the impact of video type on perpetrator-favorable responding. The findings help us better understand susceptibility to the negative impact of stereotypical sexual videos and highlight areas, such as emphasizing the suffering of victims and reducing myths about victim culpability, which may be worthy of particular emphasis in interventions.

     

Predictors of post-event rumination related to social anxiety

Post-event processing is the cognitive rumination that follows social events in cognitive models of social anxiety. The aim of this study was to examine factors that may predict the extent to which individuals engage in post-event processing. Anxious rumination, social anxiety, anxiety sensitivity and post-event processing related to a recent anxiety-provoking social event were assessed in a college student sample (n = 439). Social anxiety and anxious rumination, but not anxiety sensitivity, significantly predicted the extent to which the participants engaged in post-event processing related to an anxiety-provoking social event. Factors that appear to impact on the post-event period include the nature of the social situation and the ethnicity of the participant. It appears that both general rumination over anxious symptoms, and specific rumination related to social events are relevant for cognitive models of social anxiety.     

Enriching the environment of alphaCaMKIIT286A mutant mice reveals that LTD occurs in memory processing but must be subsequently reversed by LTP

alphaCaMKII(T286A) mutant mice lack long-term potentiation (LTP) in the hippocampal CA1 region and are impaired in spatial learning. In situ hybridization confirms that the mutant mice show the same developmental expression of alphaCaMKII as their wild-type littermates. A simple hypothesis would suggest that if LTP is a substrate for learning, then enriching the environment should cause learning-dependent changes in wild-type mice that have LTP. Such changes would not be seen in LTP-deficient alphaCaMKII(T286A) mutants. Excitatory synaptic currents in CA1 neurons, recorded with patch clamp in brain slices, revealed that enrichment induces an increase in glutamate release probability and a decreased miniature current amplitude. Confocal microscopy also showed dendritic spine density to be reduced. However, contrary to the hypothesis above, these enrichment-induced changes occur only in the mutant mice and are not detectable in wild-type littermates. We suggest that enrichment induces alphaCaMKII-independent changes in both wild-type and mutant mice. Such changes may be subsequently reversed in wild-type animals via alphaCaMKII-dependent mechanisms, such as LTP. Reversal of plasticity has long been hypothesized to be essential for the hippocampus to maintain its role in memory processing. The inability to reverse plasticity in alphaCaMKII(T286A) mutant mice would then result in impairment of spatial learning.     

Rumination-focused cognitive behaviour therapy for residual depression: a case series

The treatment of chronic and recurrent depression is a priority for the development of new interventions. The maintenance of residual symptoms following acute treatment for depression is a risk factor for both chronic depression and further relapse/recurrence. This open case series provides the first data on a cognitive-behavioural treatment for residual depression that explicitly targets depressive rumination. Rumination has been identified as a key factor in the onset and maintenance of depression, which is found to remain elevated following remission from depression. Fourteen consecutively recruited participants meeting criteria for medication--refractory residual depression [Paykel, E.S., Scott, J., Teasdale, J.D., Johnson, A.L., Garland, A., Moore, R. et al., 1999. Prevention of relapse in residual depression by cognitive therapy--a controlled trial. Archives of General Psychiatry 56, 829-835] were treated individually for up to 12 weekly 60-min sessions. Treatment specifically focused on switching patients from less helpful to more helpful styles of thinking through the use of functional analysis, experiential/imagery exercises and behavioural experiments. Treatment produced significant improvements in depressive symptoms, rumination and co-morbid disorders: 71% responded (50% reduction on Hamilton Depression Rating Scale) and 50% achieved full remission. Treating depressive rumination appears to yield generalised improvement in depression and co-morbidity. This study provides preliminary evidence that rumination-focused CBT may be an efficacious treatment for medication--refractory residual depression.     

The Product of Self-Deception

I raise the question of what cognitive attitude self-deception brings about. That is: what is the product of self-deception? Robert Audi and Georges Rey have argued that self-deception does not bring about belief in the usual sense, but rather “avowal” or “avowed belief.” That means a tendency to affirm verbally (both privately and publicly) that lacks normal belief-like connections to non-verbal actions. I contest their view by discussing cases in which the product of self-deception is implicated in action in a way that exemplifies the motivational role of belief. Furthermore, by applying independent criteria of what it is for a mental state to be a belief, I defend the more intuitive view that being self-deceived that p entails believing that p. Beliefs (i) are the default for action relative to other cognitive attitudes (such as imagining and hypothesis) and (ii) have cognitive governance over the other cognitive attitudes. I explicate these two relations and argue that they obtain for the product of self-deception.

Development of the coordination between posture and manual control

Studies have suggested that proper postural control is essential for the development of reaching. However, little research has examined the development of the coordination between posture and manual control throughout childhood. We investigated the coordination between posture and manual control in children (7- and 10-year-olds) and adults during a precision fitting task as task constraints became more difficult. Participants fit a block through an opening as arm kinematics, trunk kinematics, and center of pressure data were collected. During the fitting task, the precision, postural, and visual constraints of the task were manipulated. Young children adopted a strategy where they first move their trunk toward the opening and then stabilize their trunk (freeze degrees of freedom) as the precision manual task is being performed. In contrast, adults and older children make compensatory trunk movements as the task is being performed. The 10-year-olds were similar to adults under the less constrained task conditions, but they resembled the 7-year-olds under the more challenging tasks. The ability to either suppress or allow postural fluctuations based on the constraints of a suprapostural task begins to develop at around 10 years of age. This ability, once developed, allows children to learn specific segmental movements required to complete a task within an environmental context.     

Number of Children Associated with Mothers’ Perceived Need for Behavior Support: Implications for Parenting Interventions

Researchers acknowledge mothers’ contributing role in influencing children’s behavioral displays of emotion, but there is a dearth in the literature on mothers’ emotion-related behaviors, beliefs, and needs. Urban, Head Start Mothers (n = 114) participated in a quantitative, exploratory investigation to examine child, maternal and community factors that may be associated with level of expressiveness, perceived role in emotional development, and receptivity to behavior support. Findings suggested that, compared to mothers raising two or more children, those raising only one child were significantly less positive in self-reported expressiveness, less supportive of the suggested role of mothers in the literature, and less receptive to parent-focused behavior support. Implications for acknowledging possibly distinct needs of Head Start mothers of singletons as well as seeking input from more experienced Head Start mothers in devising parenting interventions will be discussed.
