Tracking the implicit self using event-related potentials

Negative biases in implicit self-evaluation are thought to be detrimental to subjective well-being and have been linked to various psychological disorders, including depression. An understanding of the neural processes underlying implicit self-evaluation in healthy subjects could provide a basis for the investigation of negative biases in depressed patients, the development of differential psychotherapeutic interventions, and the estimation of relapse risk in remitted patients. We thus studied the brain processes linked to implicit self-evaluation in 25 healthy subjects using event-related potential (ERP) recording during a self-relevant Implicit Association Test (sIAT). Consistent with a positive implicit self-evaluation in healthy subjects, they responded significantly faster to the congruent (self–positive mapping) than to the incongruent sIAT condition (self–negative mapping). Our main finding was a topographical ERP difference in a time window between 600 and 700 ms, whereas no significant differences between congruent and incongruent conditions were observed in earlier time windows. This suggests that biases in implicit self-evaluation are reflected only indirectly, in the additional recruitment of control processes needed to override the positive implicit self-evaluation of healthy subjects in the incongruent sIAT condition. Brain activations linked to these control processes can thus serve as an indirect measure for estimating biases in implicit self-evaluation. The sIAT paradigm, combined with ERP, could therefore permit the tracking of the neural processes underlying implicit self-evaluation in depressed patients during psychotherapy.     

Water Mist Punishment for Two Classes of Problem Behaviour

A study with multiple baseline design across situations and response-classes was used to evaluate the effects of a water mist procedure used for punishment of two classes of problem behaviour in a 50-year-old woman with severe mental retardation. Problem behaviour was reduced to less than 5% of baseline. After 19 months the problem behaviour was still reduced, and had stabilized at a level below 10% of baseline. Due to financial economies the local community authorities terminated the treatment, which resulted in a marked increase in the rate of problem behaviour.     

Exploring the Construct Validity of the Social Cognition and Object Relations Scale in a Clinical Sample

The resistance of the Personal Orientation Dimensions (POD) to deliberate attempts at creating a favorable impression was investigated. Two groups of college students were used: (a) 21 students completed the POD under standard instructions, then received information about actualization, and completed the POD again under instructions to Create a very good impression; (b) 21 students completed the POD under standard instructions, then received information not related to actualization, and completed the POD again under instructions to create a very good impression. An analyses indicated that providing students with information about actualization did not facilitate their ability to create a favorable impression on the POD. The POD profiles produced by both groups changed significantly, and in a similar direction from pretest to posttest. Evidence is presented suggesting the existence of a "lie profile" which distinguishes deliberate attempts to create a favorable impression on the POD. These findings provide support for the resistance of the POD to deliberate attempts at creating a favorable impression.     

Attentional priming releases crowding

Views of natural scenes unfold over time, and objects of interest that were present a moment ago tend to remain present. While visual crowding places a fundamental limit on object recognition in cluttered scenes, most studies of crowding have suffered from the limitation that they typically involved static scenes. The role of temporal continuity in crowding has therefore been unaddressed. We investigated intertrial effects upon crowding in visual scenes, showing that crowding is considerably diminished when objects remain constant on consecutive visual search trials. Repetition of both the target and distractors decreases the critical distance for crowding from flankers. More generally, our results show how object continuity through between-trial priming releases objects that would otherwise be unidentifiable due to crowding. Crowding, although it is a significant bottleneck on object recognition, can be mitigated by statistically likely temporal continuity of the objects. Crowding therefore depends not only on what is momentarily present, but also on what was previously attended.     

Manual rotation training improves direction-estimations in a virtual environmental space

This study investigated in a virtual environment, whether the training of a small-scale ability, i.e., manual or mental rotation, has an influence on the large-scale ability to estimate a direction. Ninety-six participants completed a direction estimation task as a pretest and then received either a manual rotation or a mental rotation training or played a nonspatial computer game. After that they completed the direction estimation task once again. The results showed that the direction estimation error decreased from the pre- to posttest only for the manual rotation training group. For that, the small-scale spatial ability was at least partially related to the large-scale ability, which supports the Partial Dissociation Model.     

Dual-memory processes in crack cocaine dependents: The effects of childhood neglect on recall

Exposure to adversities during sensitive periods of neurodevelopment is associated with the subsequent development of substance dependence and exerts harmful, long-lasting effects upon memory functioning. In this study, we investigated the relationship between childhood neglect (CN) and memory using a dual-process model that quantifies recollective and non-recollective retrieval processes in crack cocaine dependents. Eighty-four female crack cocaine–dependent inpatients who did (N = 32) or did not (N = 52) report a history of CN received multiple opportunities to study and recall a short list composed of familiar and concrete words and then received a delayed-recall test. Crack cocaine dependents with a history of CN showed worse performance on free-recall tests than did dependents without a history of CN; this finding was associated with declines in recollective retrieval (direct access) rather than non-recollective retrieval. In addition, we found no evidence of group differences in forgetting rates between immediate- and delayed-recall tests. The results support developmental models of traumatology and suggest that neglect of crack cocaine dependents in early life disrupts the adult memory processes that support the retrieval of detailed representations of events from the past.

Predictors of mental distress and poor physical health among homeless women

Abstract

We tested a latent variable path model in which situational, personal, and social resources predicted several mediators and the key health outcomes of mental distress and poor physical health among 871 homeless women. Mental distress was predicted by risky sexual behavior, less social support, avoidant coping, less self-esteem, client abuse history, social support from deviant sources, less drug self-efficacy and health care utilization. Poor physical health was predicted by a client abuse history, less drug self-efficacy, fewer perceived rewards for drug use, higher perceived costs for drug use, and a doctor visit. Current risky sexual behavior was predicted by a parent drug abuse history, less drug self-efficacy, and more social support from deviant sources. Current drug use was predicted by parent drug abuse history, less drug self-efficacy, more social support from deviant sources and by high perceived costs for drug use. Implications of results for intervention and theory are discussed.     

Oral health and dental well‐being: testing a self‐determination theory model

This study tested a self‐determination theory (SDT) process model of oral health and subjective dental well‐being. The results showed that: (1) patients' perceptions of autonomy‐supportive dental professionals were significantly positively predictive of patients' psychological needs satisfaction in treatment; (2) needs satisfaction was significantly related to perceived dental competence (positive), autonomous motivation (positive), and controlled motivation (negative) for dental care; (3) perceived competence was significantly positively, and controlled motivation was significantly negatively associated with self‐rated oral health and oral‐health‐related quality of life; (4) autonomous motivation for dental treatment was significantly positively associated with valuing continued dental treatment; and (5) the three oral‐health‐related variables were all significantly positively linked to subjective dental well‐being. A structural equation model supported the SDT process model.
