Characteristics and Effectiveness of an Intensive Military Outpatient Treatment Program for PTSD

This study describes the characteristics and global effectiveness of treatment of a military intensive outpatient treatment program for posttraumatic stress disorder (PTSD). Thirty-nine military personnel completed treatment outcome questionnaires. Results showed a statistically significant reduction in depression and PTSD symptoms after the participants completed 3 weeks of intensive outpatient therapy. The findings have clinical and research implications for the length, intensity, and focus of PTSD treatment.     

Executive Function,Intellectual Decline and Daily Living Skills

ABSTRACT

Understanding the cognitive changes associated with compromised daily living skills in elderly individuals is important for making appropriate recommendations about the capacity for independent functioning. To this end, we retrospectively examined data from 92 elderly individuals presenting with cognitive decline who were administered measures of executive functioning, general intelligence, and daily living skills. Multiple regression analyses were used to examine the relationship between executive functioning and daily living skills, while controlling for age, depression, and either IQ decline or current IQ. Executive functioning accounted for additional variance in a broad range of daily living skills after controlling for IQ decline. When FSIQ was used in the regression model rather than IQ decline, executive functioning was no longer uniquely associated with daily living skills. Executive functions appear to be important for daily living skills until a critical threshold of low intellectual functioning is reached, reflecting the combined influence of premorbid ability and the extent of intellectual decline. Our results suggest that understanding the relative contribution of different cognitive domains to functional decline in elderly individuals should take into account general intellectual functioning and estimated decline, and that the initiation and/or persistence of self-directed cognitive processes may be important for adaptive daily functioning. These findings have implications for making more evidence-based recommendations about the capacity for independent living.     

Emotional impact feedback affects how people remember an analogue trauma event

Do external motivational processes—in the form of social influences—shape people's memories for trauma? In this experiment, we examined the effects of social influence on memory and post-traumatic stress disorder (PTSD) symptomology for an analogue traumatic event. Seventy-two participants watched a distressing film; some received feedback about others' reactions to the film that either emphasised or downplayed the distressing nature of the film; control participants received no feedback. A week later, participants reported their symptoms, rated their memory on a number of characteristics and we tested their memory for the film's content. Participants who received feedback downplaying the film reported fewer PTSD-related analogue symptoms and weaker memory characteristics than their counterparts. The results suggest that people's memory phenomenology and analogue symptoms are influenced by others' feedback, but only when others' reactions downplayed the distressing nature of the film.     

The Relationship between Imagery Ability and Imagery Use among Athletes

The present study aimed to provide a better understanding of the relationship between imagery ability and imagery use. Athletes completed the Movement Imagery Questionnaire—Revised Second Version, the Motivational Imagery Ability Measure for Sport, and the Sport Imagery Questionnaire. Hierarchical regression analyses revealed that imagery ability explained 20 to 41% of the variance in the use of the functions of imagery. Visual and kinesthetic imagery ability predicted cognitive specific imagery use; motivational general-mastery and motivational general-arousal imagery ability predicted the use of the motivational general functions of imagery. To assess imagery ability multiple methods of assessment must be used.     

The Innate Bases of Fear

This study addressed the effects of children's understanding of social learning principles on divergent areas of behavior: two indices of self-control, grade scores, personality and conduct problems, immaturity, and subcultural delinquency. Using an orthogonal 2 × 2 (Understanding of Social Learning Principles × Age) multivariate analysis of variance on 44 children, we found no significant interaction or a knowledge of social learning principles main effect.     

The impact of mothers' trait anxiety on their expectations of approach‐avoidance behaviour in anxious and non‐anxious children

This study investigated estimates of approach and avoidance behaviour in clinically anxious and non‐anxious children, and whether mothers' expectations of their children's avoidance differed as a function of high trait anxiety (HTA) versus low trait anxiety (LTA). Participants were 62 clinically anxious and 60 non‐anxious children aged 7–12 years and their mothers. Estimates of avoidance were obtained using an analogue task in which children and mothers were given threat and pleasant information about two novel animals and were asked to estimate children's avoidance of the threat animal's habitat when the threat animal was present (threat condition) and absent (safe condition) from the habitat and when its presence was uncertain (ambiguous condition). Contrary to expectation, anxious children did not differ from controls in estimates of avoidance in any condition. However, relative to HTA mothers of anxious children and LTA mothers of non‐anxious children, HTA mothers estimated greater approach behaviour by their non‐anxious children in the threat condition. Findings suggest that mothers' expectations of children's approach‐avoidance behaviour is influenced by both maternal and child factors.     

Fabrication Puts Suspects at Risk: Blindness to Changes in Transgression‐related Statements

Based on the finding that deceptive and misleading interrogation techniques are not uncommon, we investigated to what extent participants may be blind to alterations introduced to their accounts of past transgressions. Drawing from the source‐monitoring framework, we hypothesized that participants' truthfulness and whether they had committed a transgression in the past (transgression history) would be predictive of blindness. When filling out a questionnaire about their past transgressions, 80 participants fabricated some of their answers. Prior to an interview 1 week later, two previously fabricated and two truthful answers were covertly altered by the experimenter. We found substantial blindness rates, and, as hypothesized, blindness was more pronounced for (1) fabricated than truthful responses and (2) alterations with transgression history compared with no transgression history. Possible consequences may include the creation of guilt presumption and increasing pressure to obtain a confession. Both can be hazardous for suspects and the legal decision‐making process.

Dissociable effects of basolateral amygdala lesions on decision making biases in rats when loss or gain is emphasized

Individuals switch from risk seeking to risk aversion when mathematically identical options are described in terms of loss versus gains, as exemplified in the reflection and framing effects. Determining the neurobiology underlying such cognitive biases could inform our understanding of decision making in health and disease. Although reports vary, data using human subjects have implicated the amygdala in such biases. Animal models enable more detailed investigation of neurobiological mechanisms. We therefore tested whether basolateral amygdala (BLA) lesions would affect risk preference for gains or losses in rats. Choices in both paradigms were always between options of equal expected value—a guaranteed outcome, or the 50:50 chance of double or nothing. In the loss-chasing task, most rats exhibited strong risk seeking preferences, gambling at the risk of incurring double the penalty, regardless of the size of the guaranteed loss. In the betting task, the majority of animals were equivocal in their choice, irrespective of bet size; however, a wager-sensitive subgroup progressively shifted away from the uncertain option as the bet size increased, which is reminiscent of risk aversion. BLA lesions increased preference for the smaller guaranteed loss in the loss-chasing task, without affecting choice on the betting task, which is indicative of reduced risk seeking for losses, but intact risk aversion for gains. These data support the hypothesis that the amygdala plays a more prominent role in choice biases related to losses. Given the importance of the amygdala in representing negative affect, the aversive emotional reaction to loss, rather than aberrant estimations of probability or loss magnitude, may underlie risk seeking for losses.
