Regret resolution, aging, and adapting to loss

Both theory and empirical evidence suggest that people who have unresolved regrets experience lower levels of well-being than do those who resolve their regrets. In this study, the authors examined the role of regret resolution during bereavement by assessing whether (a) regret resolution would aid in adapting to the death of a loved one and (b) older adults would be more successful at resolving their bereavement-related regrets than would younger adults. Mixed models were run with longitudinal data from an age-heterogeneous sample of 147 men and women who were eventually bereaved after providing care for a loved one through a hospice. As expected, regret resolution contributed to adjustment as indicated by postloss patterns of depressive symptoms, well-being, and rumination; further, older adults were more likely to resolve their regrets than were younger adults. Implications for encouraging regret resolution early in bereavement are discussed.     

Gender differences in health anxiety: An investigation of the interpersonal model of health anxiety

Health anxiety (HA) involves persistent worry about one’s health and beliefs one has an illness or may contract a disease. In the present study, gender differences in Noyes et al.’s (2003) interpersonal model of health anxiety (IMHA) were examined. Using a sample of 950 undergraduates (674 women; 276 men), multigroup confirmatory factor analyses suggested the measurement model for key dimensions of the IMHA (i.e., reassurance-seeking, alienation, worry, and absorption) were invariant across gender. This suggests key dimensions of this model are applicable to and generalizable across women and men. Coefficients alpha for and bivariate correlations between these IMHA dimensions were also roughly comparable across women and men. As hypothesized, mean levels of reassurance-seeking and worry were significantly higher in women compared to men. No gender differences were observed in mean levels of alienation or absorption. Reassurance-seeking and worry appear salient in the interpersonal behavior and emotional life of women with HA. The present study helps to clarify gender differences in the IMHA and other HA models involving similar variables.     

Associations between a one-shot delay discounting measure and age, income, education and real-world impulsive behavior

There has been discussion over the extent to which delay discounting – as prototypically shown by a preference for a smaller-sooner sum of money over a larger-later sum – measures the same kind of impulsive preferences that drive non-financial behavior. To address this issue, a dataset was analyzed containing 42,863 participants’ responses to a single delay-discounting choice, along with self-report behaviors that can be considered as impulsive. Choice of a smaller-sooner sum was associated with several demographics: younger age, lower income, and lower education; and impulsive behaviors: earlier age of first sexual activity and recent relationship infidelity, smoking, and higher body mass index. These findings suggest that at least an aspect of delay discounting preference is associated with a general trait influencing other forms of impulsivity, and therefore that high delay discounting is another form of impulsive behavior.     

The influence of perceptual and semantic categorization on inhibitory processing as measured by the N2–P3 response

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event Related Potentials (ERPs). Participants completed three Go–NoGo tasks that increased systematically in the degree of conceptual-semantic information necessary to respond correctly (from single items to categories of objects and animals). Findings indicate that the N2 response reflects inhibitory processing but does not change significantly with task difficulty. The P3 NoGo amplitude, on the other hand, is attenuated by task difficulty. Further, the latency of the peak of the P3 NoGo response elicited by the most difficult task is significantly later than are the peaks detected during performance of the other two tasks. Thus, the level of complexity of conceptual-semantic representations influences inhibitory processing in a systematic way. This inhibition paradigm may be a key for investigating inhibitory dysfunction in patient populations.     

Perceptual interactions in a minimalist virtual environment

How in real-life or through the use of technical devices can we recognize the presence of other persons and under what conditions can we differentiate them from objects? In order to approach this question, in the study reported here we explored the most basic conditions necessary for participants to recognize the presence of another person during a perceptual interaction. We created a mini-network of two minimalist devices and investigated whether participants were able to differentiate the perception of another person from the perception of a fixed and a mobile object even when the pattern of sensory stimulation was reduced to a bare minimum. We show that participants can recognize when the all-or-none tactile stimulation they experienced was attributable to an encounter with the other participant's avatar or the mobile object rather than with a fixed object. Participants were also able to establish different strategies in order to favor the situations of mutual perception. Thus, in the minimalist conditions of our experiment, the perception of another intentional subject was not based purely on any particular shape or objective trajectories of displacement; it was also based on properties that are intrinsic to the joint perceptual activity itself.     

Use of a structured investigative protocol enhances the quality of investigative interviews with alleged victims of child sexual abuse in Britain

One hundred alleged victims of child sexual abuse (aged 4–13; M = 9.3 years) were interviewed by police investigators about their alleged experiences. Half of the children were interviewed using the National Institute of Child Health and Human Development (NICHD) structured interview Protocol, whereas the other children, matched with respect to their age, relationship with the alleged perpetrator, and seriousness of the alleged offenses, were interviewed by investigators following the Memorandum of Good Practice. Protocol‐guided interviews elicited more information using free‐recall invitations and less information using directive, option‐posing and suggestive questions than did standard Memorandum interviews. There were no age differences in the proportion of total information provided in response to open‐ended invitations in either condition, but there was a significant increase with age in the proportion of central information provided in response to open‐ended invitations.

The development of the Body Morph Assessment version 2.0 (BMA 2.0): Tests of reliability and validity

This study tested the psychometric characteristics of the Body Morph Assessment version 2.0 (BMA 2.0). A sample of 563 adults composed of four groups classified by gender and ethnicity (Caucasian men and women and African-American men and women) were studied. Support for the internal consistency and test–retest reliability of the BMA 2.0 was found for both men and women. A study of convergent validity was conducted. The BMA 2.0 was found to have adequate reliability and validity. Norms were established for the BMA 2.0 estimates of current body size (CBS), ideal body size (IBS), and acceptable body size (ABS) for Caucasian and African-American men and women. In summary, the BMA 2.0 is a reliable and valid computerized measure of CBS, IBS, ABS, the CBS–IBS discrepancy (body dissatisfaction), and provides an estimate of over/underestimation of body size as compared to individuals of the same sex and body mass index.     

Using SMS text messaging for teaching and data collection in the behavioral sciences

Recent interest in university teaching has focused on interactivity in lectures and practical classes, and teachers in several fields have set up systems in which students can interact with the lecturer using mobile-phonebased SMS text messaging. This approach has particular potential in psychology, where students could use SMS messaging as a way of responding in simple psychology experiments or demonstrations. We describe a simple architecture for an SMS-based responding, using an SMS-to-HTTP message relay service, and a PHP/MySQL input-output handler. We describe briefly two experiments we have run using the system. The first experiment examined anchoring effects in an SMS-based auction. The second experiment examined delay discounting, with participants indicating their intertemporal preferences using SMS. Finally, we evaluate the feedback we obtained from students about the practical and conceptual issues surrounding text-message-based responding.     

Increased sensitivity to the disinhibiting effects of alcohol in binge drinkers.

Heavy episodic alcohol use, or binge drinking, is a serious public health problem. Binge drinking is endemic in college students and has resulted in numerous alcohol-related tragedies, including acute alcohol poisonings, falls, and automobile collisions. Such negative outcomes might occur because binge drinkers are generally more impulsive, and this impulsivity might be exacerbated under alcohol. The purpose of this study was to examine this hypothesis by comparing the acute effects of alcohol on a cognitive measure of behavioral control in binge and nonbinge drinkers. The results indicated that binge drinkers act more impulsively and report feeling more stimulated under an acute 0.65 g/kg dose of alcohol compared to nonbinge drinkers. The present finding of a heightened disinhibitory reaction to alcohol in binge drinkers may help explain the link between impulsivity and problem drinking at a more fundamental level of behavioral control.     

Experiential avoidance and aversive visual images: response delays and event-related potentials on a simple matching task

In Experiment 1, participants high (n=15) or low in avoidance (n=14), as measured by the Acceptance and Action Questionnaire, completed a simple matching task that required them to choose whether or not to look at an aversive visual image. Only the high-avoidance participants took longer to emit a correct response that produced an aversive rather than a neutral picture. Additionally, the high-avoiders reported greater levels of anxiety following the experiment even though they rated the aversive images as less unpleasant and less emotionally arousing than their low-avoidant counterparts. In Experiment 2, three groups, representing high-, mid- and low-avoidance (n=6 in each) repeated the matching task with the additional recording of event-related potentials (ERPs). The findings of Experiment 1 were replicated in terms of reaction times and subjective ratings. The ERPs confirmed that the participants attended to the content of the images and differentiated between the aversive and neutral image types. The ERPs also showed significantly greater negativity for electrodes over the left hemisphere relative to the midline for only the high-experiential avoidance (EA) group. Given the left hemisphere dominance for language, the data suggest that the high-EA group engaged in verbal strategies to regulate their emotional responses.
