Does mediator use contribute to the spacing effect for cued recall? Critical tests of the mediator hypothesis

When study is spaced across sessions (versus massed within a single session), final performance is greater after spacing. This spacing effect may have multiple causes, and according to the mediator hypothesis, part of the effect can be explained by the use of mediator-based strategies. This hypothesis proposes that when study is spaced across sessions, rather than massed within a session, more mediators will be generated that are longer lasting and hence more mediators will be available to support criterion recall. In two experiments, participants were randomly assigned to study paired associates using either a spaced or massed schedule. They reported strategy use for each item during study trials and during the final test. Consistent with the mediator hypothesis, participants who had spaced (as compared to massed) practice reported using more mediators on the final test. This use of effective mediators also statistically accounted for some – but not all of – the spacing effect on final performance.     

Experience of Parental Marital Dissolution Earlier in Life and the Disposition to Forgive Among Older Violent and Non-Violent Prisoners

The purpose of this study was to examine differences in self-reported dispositional forgiveness types among older male prison inmates who experienced parental separation/divorce earlier in life. Participants included a sample of N = 261 incarcerated men, aged 45 and older, residing in state-managed prisons in Oklahoma. IBM/SPSS 22.0 was used to examine mean differences across forgiveness of self, situation, and others. Significant mean differences were evident only for forgiveness of situation. In particular, significant differences emerged relative to depressive affect F (1, 192) = 19.90, p < .001, and social support F (1, 192) = 18.64, p < .001. After controlling for age, race, religiosity, depression, social support, perceived health, crime type, and parental separation/divorce, one significant interaction (crime type X parental separation/divorce) emerged, F (1, 192) = 4.42, p < .05. It appears that the disposition to forgive the situation among older prison inmates depends on criminal offender type as well as whether the older inmate experienced parental dissolution earlier in life. Implications for pastoral counseling programing and forgiveness therapy treatment for older male prison inmates who experienced parental separation/divorce earlier in life are discussed.     

COMT genotype influences prefrontal response to emotional distraction

Early studies of genetic effects on brain activity have been conducted to investigate primarily either the influence of polymorphisms in dopaminergic genes, especially the catechol-O-methyltransferase (COMT) gene, on prefrontal cognitive processes such as working memory, or that of polymorphisms in the serotonin transporter gene on the amygdala response to threatening stimuli. Here, we address genetic influences on the neural systems underlying cognitive-affective interactions. Specifically, we assess the effect of the COMT val¹⁵⁸met polymorphism on frontal regulation of attention under emotional distraction. Healthy volunteers were scanned while performing a house-matching task with affectively negative versus neutral distractors. Effects of val allele load were examined on frontal regions associated with attentional control and emotion regulation, and on parahippocampal regions associated with perception of houses. As we predicted, val load correlated positively with activity in control- and task-related regions during performance under emotional distraction. These findings provide an initial step toward identifying genetic contributions to interindividual variability in recruitment of mechanisms that regulate affective processing.     

Exploring the effect of stress on mood, self-esteem, and daily habits with psychology graduate students

There are few empirical studies on the issues of psychology graduate students beyond dissertation research. Data from a sample of 65 psychology graduate students were analyzed to explore how stress relates to self-esteem, mood, and daily habits (eating, sleeping, smoking, exercise, and alcohol consumption). The results suggest that sleep patterns, exercise habits, and negative mood were significant correlates and predictors of stress. Findings prompt further investigation of the effects of the stress on psychology graduate students, which might aid in developing interventions leading to increased productivity, satisfaction, and global well-being for both graduate students and faculty.     

Adolescent–parent attachment as a mediator of relations between parenting and adolescent social behavior and wellbeing in China

The purpose of this study was to examine links between parenting dimensions (authoritative parenting, psychological control, and parental authority) and adolescent wellbeing (self‐esteem, autonomy, and peer attachments) as mediated by parent–teen attachment, among Chinese families. The sample included 298 Chinese adolescents, ages 15–18 years (M age = 16.36, SD = .68; 60% female). The mediation model was examined using path analyses (one model with parental authority as overprotection, and one with it as perceived behavioral control). To improve model fit a direct path was added from authoritative parenting to autonomy. Authoritative parenting was positively predictive of attachment, while psychological control and overprotection (but not behavioral control) were negative predictors. In turn, adolescent–parent attachment was positively related to the three outcomes. Lastly, the model paths did not differ by adolescent gender. These findings suggest that parenting behaviors may play a crucial role in adolescent social behaviors and wellbeing via adolescent–parent attachment.     

Acceptance and Commitment Therapy for Eating Disorders: Rationale and Literature Review

Empirical studies using Acceptance and commitment therapy (ACT) and its components to treat eating disorders (EDs) were reviewed. Evidence suggests that emotional avoidance is a major component in the onset and maintenance of EDs. Acceptance and commitment therapy targets emotional avoidance and control strategies with six core processes. These core processes have been applied to EDs and demonstrated improvement in subjects’ functioning and reduction in disordered eating. There are several advantages of using ACT for treating EDs: ACT fundamentally equalizes the therapeutic relationship; experiential techniques in ACT may facilitate lasting treatment gains; ACT navigates the ego-syntonic nature of EDs; the ACT conceptualization based on experiential avoidance and cognitive rigidity in EDs is consistent with current literature. The six core processes of ACT can be further modified to fit the challenges of treating EDs. Specifically, concerns about client motivation for treatment can be addressed by emphasizing creative hopelessness and a values construction process earlier in treatment.     

Ideological parsimony

The theoretical virtue of parsimony values the minimizing of theoretical commitments, but theoretical commitments come in two kinds: ontological and ideological. While the ontological commitments of a theory are the entities it posits, a theory’s ideological commitments are the primitive concepts it employs. Here, I show how we can extend the distinction between quantitative and qualitative parsimony, commonly drawn regarding ontological commitments, to the domain of ideological commitments. I then argue that qualitative ideological parsimony is a theoretical virtue. My defense proceeds by demonstrating the merits of qualitative ideological parsimony and by showing how the qualitative conception of ideological parsimony undermines two notable arguments from ideological parsimony: David Lewis’ defense of modal realism and Ted Sider’s defense of mereological nihilism.
