Emotional enhancement effect of memory: removing the influence of cognitive factors

According to the modulation hypothesis, arousal is the crucial factor in the emotional enhancement of memory (EEM). However, the multifactor theory of the EEM recently proposed that cognitive characteristics of emotional stimuli, e.g., relatedness and distinctiveness, also play an important role. The current study aimed to investigate the individual contribution of arousal to the neural correlates of the EEM by controlling for these additional cognitive factors. We observed the characteristic neuronal correlates of the EEM, in particular enhanced activity in the amygdala and hippocampus, which provides evidence for an arousal-driven EEM in the amygdala as proposed by the modulation hypothesis.     

When the half-full glass is appraised as half empty and memorised as completely empty: mood-congruent true and false recognition in depression is modulated by salience

Since the 1980s a large body of empirical effort has been devoted to mood-congruent memory (MCM) biases in clinical depression. Whereas there is broad, albeit not unequivocal, evidence that depressive patients retain negative-valenced memory items better than neutral material, few studies have investigated false memories in depression. In a pilot study we gathered support for both enhanced true and false memory for emotional material in depression. The present study aimed to extend these preliminary findings. In view of investigations suggesting that arousing and meaningful stimuli have facilitated access to memory, personal salience was considered a moderator for MCM. In the present study 21 depressed and 22 healthy participants were presented six false memory lists dealing with neutral, negative, and positive themes. At recognition, each item had to be appraised for its degree of valence subsequent to an old-new judgement. Pre-categorised and subjective valence did not discriminate groups. However, relative to controls depressed patients showed both more veridical as well as false recognition for items that concurrently elicited higher salience ratings in patients. In contrast, group differences in recognition performance did not significantly affect salience ratings. Results indicate that salience modulates MCM and may account for discrepancies in the literature.     

A Case Study of Cognitive-Behavioral Conjoint Therapy for Combat-Related PTSD in a Same-Sex Military Couple

Military deployments to Iraq and Afghanistan are associated with increased risk for posttraumatic stress disorder (PTSD), depression, and relationship impairment. Unfortunately, the perceived stigma associated with seeking deployment-related behavioral health care in military settings has been a significant barrier to care. Historically, active-duty military service members involved in same-sex intimate relationships have experienced further stressors and barriers to care related to additional stigma and lack of social support. Prior federal regulations excluded sexual minorities from openly serving in the military, thereby limiting the available behavioral health services for same-sex couples. Since this ban was lifted after the repeal of the U.S. policy known as "Don’t Ask, Don’t Tell" in 2010, gay and lesbian service members have increased opportunities to obtain behavioral health care. One therapy that is newly available to sexual minority military couples is Cognitive-Behavioral Conjoint Therapy (CBCT), which effectively addresses co-occurring PTSD and relationship dysfunction. This case study illustrates the use of CBCT for the treatment of deployment-related PTSD in a same-sex active-duty military couple. After completing all 15 CBCT sessions, the couple reported clinically meaningful changes in the service member’s PTSD symptoms, which was maintained at the 2-month follow-up. The results of this case study indicate that CBCT for PTSD can have positive treatment outcomes with military same-sex couples. Further clinical implications are discussed.     

Understanding Gender and Intimate Partner Violence from an International Perspective

This paper reviews the international literature on intimate partner violence with a focus on gender differences in perpetration and victimization rates. A total of 35 studies from 21 countries are discussed that report prevalence or incidence rates of men’s and women’s involvement in physical and/or sexual aggression against an intimate partner. In addition, evidence on risk factors as well as consequences of intimate partner violence for men and women is presented. Conceptual and methodological differences between the studies and the lack of comparable databases within countries are discussed as limitations of the evidence, and perspectives for future research are outlined in the framework of cross-cultural psychology.     

Mathematical models in Newton's Principia: A new view of the ‘Newtonian Style’

In this essay I argue against I. Bernard Cohen's influential account of Newton's methodology in the Principia: the ‘Newtonian Style’. The crux of Cohen's account is the successive adaptation of ‘mental constructs’ through comparisons with nature. In Cohen's view there is a direct dynamic between the mental constructs and physical systems. I argue that his account is essentially hypothetical‐deductive, which is at odds with Newton's rejection of the hypothetical‐deductive method. An adequate account of Newton's methodology needs to show how Newton's method proceeds differently from the hypothetical‐deductive method. In the constructive part I argue for my own account, which is model based: it focuses on how Newton constructed his models in Book I of the Principia. I will show that Newton understood Book I as an exercise in determining the mathematical consequences of certain force functions. The growing complexity of Newton's models is a result of exploring increasingly complex force functions (intra‐theoretical dynamics) rather than a successive comparison with nature (extra‐theoretical dynamics). Nature did not enter the scene here. This intra‐theoretical dynamics is related to the ‘autonomy of the models’.     

Shielding voices: The modulation of binding processes between voice features and response features by task representations

Vocal events offer not only semantic-linguistic content but also information about the identity and the emotional-motivational state of the speaker. Furthermore, most vocal events have implications for our actions and therefore include action-related features. But the relevance and irrelevance of vocal features varies from task to task. The present study investigates binding processes for perceptual and action-related features of spoken words and their modulation by the task representation of the listener. Participants reacted with two response keys to eight different words spoken by a male or a female voice (Experiment 1) or spoken by an angry or neutral male voice (Experiment 2). There were two instruction conditions: half of participants learned eight stimulus-response mappings by rote (SR), and half of participants applied a binary task rule (TR). In both experiments, SR instructed participants showed clear evidence for binding processes between voice and response features indicated by an interaction between the irrelevant voice feature and the response. By contrast, as indicated by a three-way interaction with instruction, no such binding was found in the TR instructed group. These results are suggestive of binding and shielding as two adaptive mechanisms that ensure successful communication and action in a dynamic social environment.     

Determining who to question, what to ask, and how much information to ask for: the development of inquiry in young children

To obtain reliable information, it is important to identify and effectively question knowledgeable informants. Two experiments examined how age and the ease of distinguishing between reliable and unreliable sources influence children’s ability to effectively question those sources to solve problems. A sample of 3- to 5-year-olds was introduced to a knowledgeable informant contrasted with an informant who always gave inaccurate answers or one who always indicated ignorance. Children were generally better at determining which informant to question when a knowledgeable informant was contrasted with an ignorant informant than when a knowledgeable informant was contrasted with an inaccurate informant. In some cases, age also influenced the ability to determine who to question and what to ask. Importantly, in both experiments, the strongest predictor of accuracy was whether children had acquired sufficient information; successful problem solving required integrating knowledge of who to question, what to ask, and how much information to ask for.     

A comparison of methods for teaching receptive labeling to children with autism spectrum disorders

Many early intervention curricular manuals recommend teaching auditory-visual conditional discriminations (i.e., receptive labeling) using the simple-conditional method in which component simple discriminations are taught in isolation and in the presence of a distracter stimulus before the learner is required to respond conditionally. Some have argued that this procedure might be susceptible to faulty stimulus control such as stimulus overselectivity (Green, 2001). Consequently, there has been a call for the use of alternative teaching procedures such as the conditional-only method, which involves conditional discrimination training from the onset of intervention. The purpose of the present study was to compare the simple-conditional and conditional-only methods for teaching receptive labeling to 3 young children diagnosed with autism spectrum disorders. The data indicated that the conditional-only method was a more reliable and efficient teaching procedure. In addition, several error patterns emerged during training using the simple-conditional method. The implications of the results with respect to current teaching practices in early intervention programs are discussed.     

The Effects of Instructions on Mothers’ Ratings of Child Attention-Deficit/Hyperactivity Disorder Symptoms

We examined whether instructional materials describing how to rate child ADHD symptoms would improve the accuracy of mothers’ ratings of ADHD symptoms presented in standard child behavior stimuli, and whether instructions would be equally effective across a range of maternal depressive symptoms and family incomes. A community sample of 100 mothers with 5 to 12 year old sons were randomly assigned to either receive or not receive the instructions. All mothers watched standard video recordings of boys displaying nonproblem behavior, ADHD symptoms, ADHD plus oppositional behaviors, or ADHD plus anxious behaviors, and then rated the ADHD symptoms of the boys in the videos. These ratings were compared to ratings of the boys’ ADHD symptoms made by objective coders. Results indicated an interaction such that the instructional materials improved the agreement between mothers’ and coders’ ratings, but only for mothers at lower family income levels. The instructional materials improved all mothers’ open-ended responses regarding knowledge of ADHD. All mothers rated more ADHD symptoms in boys with comorbid oppositional or anxious behaviors, and this effect was not reduced by the instructional materials. The potential utility of these instructions to improve the accuracy of ratings of child ADHD symptoms is explored.
