Binocular rivalry: a window into emotional processing in aging

Previous binocular rivalry studies with younger adults have shown that emotional stimuli dominate perception over neutral stimuli. Here we investigated the effects of age on patterns of emotional dominance during binocular rivalry. Participants performed a face/house rivalry task where the emotion of the face (happy, angry, neutral) and orientation (upright, inverted) of the face and house stimuli were varied systematically. Age differences were found with younger adults showing a general emotionality effect (happy and angry faces were more dominant than neutral faces) and older adults showing inhibition of anger (neutral faces were more dominant than angry faces) and positivity effects (happy faces were more dominant than both angry and neutral faces). Age differences in dominance patterns were reflected by slower rivalry rates for both happy and angry compared to neutral face/house pairs in younger adults, and slower rivalry rates for happy compared to both angry and neutral face/house pairs in older adults. Importantly, these patterns of emotional dominance and slower rivalry rates for emotional-face/house pairs disappeared when the stimuli were inverted. This suggests that emotional valence, and not low-level image features, were responsible for the emotional bias in both age groups. Given that binocular rivalry has a limited role for voluntary control, the findings imply that anger suppression and positivity effects in older adults may extend to more automatic tasks.     

Management and treatment of stalkers: problems, options, and solutions

Legal sanctions alone are often ineffective in preventing stalking because, in the absence of treatment, the fundamental problems driving the stalker remain unresolved. Criminal justice interventions can be problematic because of difficulties in framing anti-stalking legislation and inconsistencies in their application. Civil remedies in the form of restraining orders may be ineffective or counterproductive. Treatment of stalkers involves pharmacotherapy when mental illness is present, but the mainstays of treatment for non-psychotic stalkers are programmes of psychological intervention. These depend on accurate assessment of the risks inherent in stalking and on the identification of psychological deficits, needs, and responsivity factors specific to the individual. Treatment can then be tailored to suit the stalker, thereby enhancing therapeutic efficacy. Developing a framework for identifying the risk factors and shaping the delivery of treatment is crucial. Two service innovations developed specifically to work with stalkers are presented as options to overcome current management deficiencies.     

Effects of pre-experimental knowledge on recognition memory

The influence of pre-experimental autobiographical knowledge on recognition memory was investigated using as memoranda faces that were either personally known or unknown to the participant. Under a dual process theory, such knowledge boosted both recollection- and familiarity-based recognition judgements. Under an unequal variance signal detection model, pre-experimental knowledge increased both the variance and the separation of the target and foil memory strength distributions, boosting hits and correct rejections. Thus, pre-experimental knowledge has profound effects on the multiple, interacting processes that subserve recognition memory, and likely in the neural systems that underpin them.     

Psychometric properties of the Miranda Rights Comprehension Instruments with a juvenile justice sample

This article describes the psychometric properties of the Miranda Rights Comprehension Instruments, the revised version of Grisso's Miranda instruments. The original instruments demonstrated good reliability and validity in a normative sample. The revised instruments updated the content of the original instruments and were administered to a sample of 183 youth in pre- and postadjudication facilities. Analyses were conducted to establish the psychometric properties of the revised instruments and included similar analyses to those conducted by Grisso, as well as additional calculations (e.g., standard errors of measurement, intraclass correlation coefficients, Kappa coefficients). Results revealed sound psychometric properties, similar to those observed for the original instruments.     

Weight criticalness of others in restrained and unrestrained eaters

This study examined whether restrained eaters are more critical of others' body weight than unrestrained eaters. Fifty-seven female undergraduates were shown photos of a female subject described as either 18-years old (peer) or 30-years old (non-peer); they then completed measures assessing direct and indirect weight criticalness. To measure direct criticalness, participants indicated the degree to which they felt each target was too thin or too heavy. To measure indirect criticalness, participants reported how much they thought each target weighed and how much she should ideally weigh; estimated weight was then subtracted from ideal weight. Findings revealed the restrained eaters were more indirectly critical of the peer target. Specifically, the restrained eaters thought the peer target should weigh 9.42 lbs less than her current weight, whereas the unrestrained eaters reported she should weigh 3.84 lbs less. Results suggest that restrained eaters are more critical of their peers' body weight than unrestrained eaters.     

Time to face it! Facebook intrusion and the implications for romantic jealousy and relationship satisfaction

Young people's exposure to social network sites such as Facebook is increasing, along with the potential for such use to complicate romantic relationships. Yet, little is known about the overlaps between the online and offline worlds. We extended previous research by investigating the links between Facebook intrusion, jealousy in romantic relationships, and relationship outcomes in a sample of undergraduates currently in a romantic relationship. A Facebook Intrusion Questionnaire was developed based on key features of technological (behavioral) addictions. An eight-item Facebook Intrusion Questionnaire with a single-factor structure was supported; internal consistency was high. Facebook intrusion was linked to relationship dissatisfaction, via jealous cognitions and surveillance behaviors. The results highlight the possibility of high levels of Facebook intrusion spilling over into romantic relationships, resulting in problems such as jealousy and dissatisfaction. The results have implications for romantic relationships and for Facebook users in general.     

An examination of the relation between traumatic event exposure and panic-relevant biological challenge responding among adolescents

The current study uniquely extended research that has linked traumatic event exposure to panic-spectrum problems among adolescents. It was hypothesized that among 127 adolescents (age range: 10 to 17 years; M = 14.63, SD = 2.24), those who endorsed a history of traumatic event exposure would evidence significantly greater anxious and fearful reactivity to a well-established 3-min voluntary hyperventilation procedure compared to nonexposed individuals. Results were consistent with hypotheses, suggesting traumatic event exposure is associated with anxious and fearful reactivity to abrupt increases in bodily arousal among adolescents. Moreover, consistent with hypotheses, anxiety sensitivity significantly mediated the relations between traumatic event exposure and both self-reported panic symptoms and panic symptoms elicited by the challenge. Future prospective research is now needed to better understand temporal relations between traumatic event exposure and indices of panic and related vulnerability.     

Maternal depressive history, teen 5HTTLPR genotype, and the processing of emotional faces: Exploring mechanisms of risk

Variations in the serotonin transporter gene (5HTTLPR) and biased processing of face-emotion displays both have been implicated in the transmission of depression risk, but little is known about developmental influences on these relationships. Within a community sample of adolescents, we examine whether 5HTTLPR genotype moderates the link between maternal depressive history and errors in face-emotion labeling. When controlling for current levels of depression and anxiety among youth, a two-way interaction between maternal depressive history and 5HTTLPR genotype was detected. Specifically, adolescents whose mothers reported a depressive history and who had a low expressing genotype made more errors in classifying emotional faces when compared with adolescents with an intermediate or high expressing genotype, with or without maternal depression history. These findings highlight the complex manner in which maternal depression and genetic risk may interact to predict individual differences in social information processing.
