Using Imagery Techniques to Treat PTSD Symptoms in Bereaved Individuals

Certain bereaved individuals experience traumatic images of the deceased and corresponding avoidance of thoughts and feelings pertaining to the loss. This reaction resembles Post-Traumatic Stress Disorder and should benefit from treatment strategies such as imagery techniques. Accordingly, a cognitive-behavioral treatment method involving imagery work designed to replace the bereaved individual's distorted, painful memories with less aversive, more representative memories is outlined. Additionally, specific cognitive-behavioral techniques such as tests of evidence, thought diaries, and grief letters are described. Finally, contraindications and limitations are delineated.     

Food-related stimuli increase desire to eat in hungry and satiated human subjects

In the present study, the effect of food-related cues on the desire to eat chocolate in hungry and satiated subjects was investigated. Subjects (n=46) were randomly assigned to either a hungry or satiated group and then assigned to a group receiving one of the following stimuli: taste (2 M&Ms), sight (a photograph of M&Ms), cognition (a passage describin M&Ms), or control (no stimulus). In each testing session, subjects rated their desire to eat chocolate before and after the 90-s presentation of the particular stimulus. Each subject was then given a half pound of M&Ms so that actual consumption could also be measured. Results indicated that, following the presentation of the sight and taste stimuli, the subjects’ desire to eat chocolate was significantly increased. Furthermore, no differences in chocolate consumption due to state of hunger or type of food-related stimulus presented were found.     

Remembering the message: the use of a reminder cue to increase condom use following a safer sex intervention.

Condom use interventions may be more powerful if they provide cues to recall safe-sex messages when sexual activity occurs. The authors tested this notion by assigning sexually active introductory psychology students (N = 196) to a standard safe-sex intervention, a safe-sex with reminder intervention, or a control (drinking and driving) intervention. Participants assigned to the reminder intervention were given a "friendship bracelet" to wear and were instructed to have the bracelet remind them of the intervention. In a follow-up session (5-7 weeks later), they were asked questions pertaining to condom use. Of the 125 participants who had engaged in sexual intercourse, condom use at last intercourse was higher in the bracelet condition (55%) than in the standard (27%) or control (36%) conditions. The authors also found that the bracelet remained effective, even when participants were under the influence of alcohol. These findings therefore imply that health intervention programs may be more efficacious if they include strategies such as reminder cues to increase the salience of health information in the appropriate contexts.     

Assessing measurement equivalence across rating sources: a multitrait-multirater approach

Research examining the structure of multisource performance ratings has demonstrated that ratings are a direct function of both who is doing the rating (rating source) as well as what is being rated (performance dimension). A separate line of research has focused on the extent to which performance ratings are equivalent across sources. To date no research has examined the measurement equivalence of multisource ratings within the context of both dimension and rating source direct effects on ratings. We examine the impact of both performance dimension and rating source as well as the degree of measurement equivalence across sources. Results indicate that (a) the impact of the underlying performance dimension is the same across rating sources, (b) the impact of rating source is substantial and only slightly smaller than the impact of the underlying performance dimension, and (c) the impact of rating source differs substantially depending on the source.     

Promoting success or preventing failure: cultural differences in motivation by positive and negative role models

In two studies, cross-cultural differences in reactions to positive and negative role models were examined. The authors predicted that individuals from collectivistic cultures, who have a stronger prevention orientation, would be most motivated by negative role models, who highlight a strategy of avoiding failure; individuals from individualistic cultures, who have a stronger promotion focus, would be most motivated by positive role models, who highlight a strategy of pursuing success. In Study 1, the authors examined participants' reported preferences for positive and negative role models. Asian Canadian participants reported finding negative models more motivating than did European Canadians; self-construals and regulatory focus mediated cultural differences in reactions to role models. In Study 2, the authors examined the impact of role models on the academic motivation of Asian Canadian and European Canadian participants. Asian Canadians were motivated only by a negative model, and European Canadians were motivated only by a positive model.     

Relative numerousness judgment and summation in young and old Western lowland gorillas

The relationship between age, relative numerousness judgment, and summation was investigated in 11 Western lowland gorillas (Gorilla gorilla gorilla). Experiments 1 and 2 evaluated the gorillas' ability to select the larger of 2 food quantities before and with training. The majority of gorillas did not reliably select the larger quantity in Experiment 1 until receiving training to do so in Experiment 2. Experiment 3 evaluated their ability to select the larger of 2 pairs of quantities. All gorillas selected the larger pair more often than chance, and the old were less accurate and slower than were the young. For most gorillas, performance in relative numerousness judgment with training and summation was comparable with previous reports in chimpanzees and orangutans.     

Synchrony in the onset of mental-state reasoning: evidence from five cultures

Over the past 20 years, developmental psychologists have shown considerable interest in the onset of a theory of mind, typically marked by children's ability to pass false-belief tasks. In Western cultures, children pass such tasks around the age of 5 years, with variations of the tasks producing small changes in the age at which they are passed. Knowing whether this age of transition is common across diverse cultures is important to understanding what causes this development. Cross-cultural studies have produced mixed findings, possibly because of varying methods used in different cultures. The present study used a single procedure to measure false-belief understanding in five cultures: Canada, India, Peru, Samoa, and Thailand. With a standardized procedure, we found synchrony in the onset of mentalistic reasoning, with children crossing the false-belief milestone at approximately 5 years of age in every culture studied. The meaning of this synchrony for the origins of mental-state understanding is discussed.     

Influence of emotional state on irrelevant thoughts

The fan effect paradigm was used to investigate the influence of emotional mood state on longterm memory retrieval (Anderson, 1983). Subjects learned target facts embedded in unrelated sentences to a specified criterion and were then given a happy, sad, or neutral mood induction. Mean response times (RTs) and error rates were analyzed in a speeded recognition test in which subjects distinguished between the learned facts and foil facts (foil facts were constructed by recombining the same concepts). A follow-up lexical decision task indicated that mean RT was positively correlated with an increase in the weighted proportion of irrelevant thoughts produced by subjects in an induced sad mood. Results suggest that irrelevant thoughts associated with the sad mood state interfered with more relevant, task-oriented, thoughts and support the notion that sad mood is related to a failure to inhibit irrelevant information.
