Using Cognitive Mapping to Understand Problems Experienced by Family Caregivers of Persons with Severe Physical Disabilities

Individuals who provide ongoing care for family members who have a chronic disease or disability are likely to encounter a wide array of problems that can compromise their own health and their ability to function effectively in a caregiving role. Structured focus group meetings were conducted to elicit a comprehensive list of the problems that caregivers experienced during their first year of providing care to a person with a severe physical disability. A separate group of caregivers (N = 60) individually sorted problems into piles based on their similarity and assigned relative importance to each problem. The aggregated data were analyzed with multidimensional scaling and hierarchical cluster analysis. Results indicated that caregivers cognitively organize problems along three dimensions: I. Centeredness–caregiver versus patient-oriented; II. Relationship Demands–physical versus emotional; and III. Caregiver Burden–time versus emotional. Additionally, 6 clusters of substantively similar problems were identified and prioritized in terms of personal relevance: Basic Needs (lowest); Perceived Constraints; Caregiver Challenges; Patient Resentment; Patient Withdrawal; and Patient Intrapsychic Adjustment (highest). Further examination of the organization of problems identified by caregivers should provide important insights about the experience of caregivers and how more targeted interventions can be developed to address their specific needs.     

Video game genre as a predictor of problem use

This study assessed how problem video game playing (PVP) varies with game type, or "genre," among adult video gamers. Participants (n=3,380) were adults (18+) who reported playing video games for 1 hour or more during the past week and completed a nationally representative online survey. The survey asked about characteristics of video game use, including titles played in the past year and patterns of (problematic) use. Participants self-reported the extent to which characteristics of PVP (e.g., playing longer than intended) described their game play. Five percent of our sample reported moderate to extreme problems. PVP was concentrated among persons who reported playing first-person shooter, action adventure, role-playing, and gambling games most during the past year. The identification of a subset of game types most associated with problem use suggests new directions for research into the specific design elements and reward mechanics of "addictive" video games and those populations at greatest risk of PVP with the ultimate goal of better understanding, preventing, and treating this contemporary mental health problem.     

Subliminal stimuli in the near absence of attention influence top-down cognitive control

Recent research has shown that visual stimuli can influence cognitive control functions, even if subjects are unaware of the identity of the stimuli. However, in those previous studies, subjects actively attended to the location of the subliminal stimuli. Here we assessed the role of endogenous spatial attention in such paradigms. We required subjects to quickly prepare for one of two numerical judgment tasks on the basis of the direction of motion in patches of moving dots presented in cued spatial locations. We found that irrelevant motion patches presented in the uncued spatial locations also influenced task performance. Motion in the uncued patches was weak and did not affect the perception of the cued patches. Further analyses suggested that the effect of priming by the uncued stimuli was present even for subjects who could only discriminate such stimuli at chance level. Three additional experiments confirmed that subjects paid minimal attention to the uncued locations, in that the subjects could not perform simple discriminations of conjunctions of features in those locations.     

Assessment of abnormal personality in childhood: a Delphi survey of questionnaire data

As an investigation into the feasibility of recording personality status from questionnaire data in younger people we used a three phase Delphi survey to assess items from the Christchurch Health and Development Study, administered at ages 12 to 16 years. Twelve experts took part in Phase I, and 22 in Phases II and III, 16 of whom were experts in adult personality disorder (PD), and 6 were experts who work with children. In total, 189 questions (55% of the total (238) in the questionnaires) were identified as possibly being related to personality abnormality in one or more clusters with high consensus. Experts who work with children were less likely to label features as related to personality than experts in PD (p < 0.001), and the four personality factors (equivalent to Mulder and Joyce's antisocial, asocial, asthenic, and anankastic) chosen for assessment showed variable agreement. Confirmatory factor analysis showed the best fitting model of the data was a 3 factor solution involving asocial/asthenic, antisocial, and anankastic factors. This represents the first attempt to use existing recorded data to code personality status and the results of this Delphi survey give some grounds for optimism that this approach has potential in the early identification of personality features.     

Motor inhibition associated with the affordance of briefly displayed objects

Research has demonstrated that left- and right-hand responses are facilitated when they are performed with the hand compatible with the orientation of a viewed object. This suggests that graspable objects automatically activate the motor representations that correspond to their orientation. It has recently been proposed that similar positive stimulus-response compatibility effects (PCE) may turn into negative compatibility effects (NCE) when a prime object is displayed very briefly. These NCEs are suggested to reflect motor inhibition mechanisms--motor activation triggered by briefly viewed objects may be treated by the motor system as unwanted, and thus it is rapidly inhibited. We examined whether the motor activation triggered by the orientation of a task-irrelevant object is similarly inhibited when the object is displayed briefly. In Experiment 1, a NCE was observed between the orientation of an object and the responding hand when the object was displayed for 30 or 70 ms. The effect turned into a PCE when the object was displayed for 370 ms. Experiment 2 confirmed that this motor inhibition effect was produced by the handle affordance of the object rather than some abstract visual properties of the object.     

Propensity scoring and the relationship between sexual media and adolescent sexual behavior: comment on Steinberg and Monahan (2011)

Longitudinal research has demonstrated a link between exposure to sexual content in media and subsequent changes in adolescent sexual behavior, including initiation of intercourse and various noncoital sexual activities. Based on a reanalysis of one of the data sets involved, Steinberg and Monahan (2011) have challenged these findings. However, propensity score approaches-especially the version of this method used by Steinberg and Monahan, which lacks covariates-do not necessarily result in more accurate estimates of treatment effects than does the regression with covariates approach employed by prior research. There are also a number of problems with the specific set of analyses presented by Steinberg and Monahan and the conclusion they draw from them. In contrast to Steinberg and Monahan's claim, there is substantial evidence of an association between sexual media exposure and adolescent sexual initiation.

‘A baptism of fire’: A qualitative investigation of a trainee counsellor's experience at the start of training

Background: Belief in the effectiveness of professional counselling and psychotherapy training is widespread and generally unquestioned. Few studies have attempted to understand the changes experienced by trainees, or identified which aspects of professional training programmes assist them in the process of becoming therapists. Aims: to investigate how a trainee counsellor changes at the start of training, and to identify which aspects of a professional counsellor training programme were helpful in instigating and supporting change. Method: the experience of one trainee counsellor, Margaret, was captured through three semi-structured interviews conducted at the beginning, middle and end of her first term. The data were subjected to systematic qualitative analysis. Findings: Margaret experienced significant change during her first term. Each interview revealed a different phase of her development. The core categories were: becoming something new (week 3); growth in therapeutic confidence (week 6); surviving ‘stressful involvement’ through supervision (week 11). Experiential learning, in particular group supervision, was helpful throughout. The presence of real clients was identified as the main driver for change. Conclusion: The findings were found to be consistent with a number of other studies, which suggest that training is potentially painful because of the emotional demands it places on trainees, particularly at the start of practice. Consequently trainees require opportunities for experiential learning, peer support and supportive supervision to assist them in their development, but most importantly, given that supportive supervision can only minimise the harm of stressful involvement (Orlinsky & Ronnestad, 2005), they need early positive experiences with clients.     

Perceptual load modulates the processing of distractors presented at task-irrelevant locations during the attentional blink

The distribution of attention in both space and time is critical for processing our dynamic environment. Studies of spatial attention suggest that the distribution of attention is decreased when the perceptual load of a task increases, resulting in decreased processing of task-irrelevant distractors. Studies of the attentional blink (AB) suggest that the temporal distribution of attention also influences distractor processing, such that distractor processing increases during the AB relative to outside the AB (Jiang & Chun, 2001). Two experiments are reported in which the extent to which the difficulty of the first target task (T1) modulates the processing of task-irrelevant distractors during the AB was tested. To investigate this issue, both the first and second target tasks (T1 and T2) required identifying a central stimulus that was flanked by low-load or high-load distractors. Consistent with previous studies of the AB, there was evidence of more distractor processing during the AB than outside the AB. Critically, however, the interference caused by distractors presented simultaneously with T2 during the AB was reduced when T1 perceptual load was high relative to when it was low. These results suggest that increasing T1 perceptual load decreases distractor processing during the AB and that perceptual processes influence both the temporal and spatial distribution of attention.     

Intergenerational effects of cocaine on maternal aggressive behavior and brain oxytocin in rat dams

Gestational cocaine treatment results in significantly increased maternal aggression towards an intruder by postpartum day six, while acute postpartum treatment dose dependently decreases maternal aggressive (MA) behavior. Both increased and decreased aggression in the cocaine-treated dams are correlated with either decreased or increased levels of oxytocin in the amygdala, respectively. The current study was an effort to determine whether the effect of gestational cocaine on maternal aggression is transient or would continue into the postpartum period; whether an intermittent cocaine treatment regimen, which incorporates gestational and postpartum intermittent cocaine treatment, would differ from chronic daily gestational treatment; and finally, whether next generation female offspring of cocaine-treated or control dams would have altered MA behavior and oxytocin system changes attributable to either prenatal drug exposure, rearing condition or both. We now report no increase in maternal aggression following chronic gestational treatment and significantly lower levels of aggression in intermittently treated dams on postpartum day eight, with no significant effects in either group on postpartum day 12. Young adult female offspring of the cocaine-treated and control dams, who reared their own natural litters and were tested on postpartum day eight for maternal aggression, had higher levels of maternal aggression towards an intruder attributable to both prenatal cocaine exposure and rearing condition. Higher aggression in cocaine-reared next generation dams was associated with lower levels of oxytocin in the amygdala. Intergenerational effects of cocaine were apparent with respect to aggression and oxytocin system changes.
