Increased semantic and repetition priming in schizophrenic patients

Positive and negative priming (PP and NP) in schizophrenia were studied with a lexical-decision task. Probe words, presented 800 ms after the response to the prime (containing a word and a nonword), were either identical to, semantically related to, or unrelated to the prime target word (PP) or to the prime distractor word (NP). Schizophrenic patients displayed stronger semantic and repetition PP than controls after controlling for their slower responses. Significant NP was observed in both groups for word repetition only. The PP findings contrast with results from studies with similar prime-probe intervals but without prime responses. It is proposed that schizophrenic patients, because of impaired (controlled) processes of response selection, strongly benefit from (or rely on) the automatic retrieval of processing episodes containing response information. Related findings indicating automatic response facilitation in schizophrenia are discussed.     

The practice of Modern Group Psychotherapy: working with past trauma in the present

Modern Group Psychotherapy offers specific techniques for aiding the pre-oedipal patient to speak, connect, and achieve emotional growth. This article illustrates the use of such therapeutic group tools as joining, mirroring, bridging, contact functioning, the object-oriented question, the insulation barrier, and transient identification, through case vignettes. It demonstrates how such techniques protect fragile egos and assist them on their journey to maturity. Emphasis is placed on the creative components of countertransference as a valuable supplement in patient treatment. The power of the group as an agent for change is portrayed.     

Effects of gravitational and optical stimulation on the perception of target elevation

To examine the combined effects of gravitational and optical stimulation on perceived target elevation, we independently altered gravitational-inertial force and both the orientation and the structure of a background visual array. While being exposed to 1.0, 1.5, or 2.0 Gz in the human centrifuge at NASA Ames Research Center, observers attempted to set a target to the apparent horizon. The target was viewed against the far wall of a box that was pitched at various angles. The box was brightly illuminated, had only its interior edges dimly illuminated, or was kept dark. Observers lowered their target settings as Gz was increased; this effect was weakened when the box was illuminated. Also, when the box was visible, settings were displaced in the same direction as that in which the box was pitched. We attribute our results to the combined influence of otolith-oculomotor mechanisms that underlie the elevator illusion and visual-oculomotor mechanisms (optostatic responses) that underlie the perceptual effects of viewing pitched visual arrays.     

Relationship Between Specific Adverse Life Events and Psychiatric Disorders

This study examines whether certain psychiatric disorders are associated more closely with adverse life events than other disorders are, and whether some adverse life events are associated with a specific group of disorders (e.g., depressive disorders), but not with other disorders (e.g., anxiety disorders). A probability sample of youth aged 9–17 at 4 sites is used (N = 1,285). Univariate and multivariate logistic regressions identify specific relationships between 25 adverse life events and 9 common child and adolescent psychiatric disorders, measured by the Diagnostic Interview Schedule for Children. Conduct Disorder, Oppositional Defiant Disorder, Major Depressive Disorder, and Dysthymia are significantly associated with many of the adverse life events examined, whereas Attention Deficit/Hyperactivity Disorder, Agoraphobia, and Social Phobia are related to very few. This study suggests that certain psychiatric disorders may be more closely associated with adverse life events than other psychiatric disorders are, and that some adverse life events seem to be related to specific types of disorders.     

Using magnitude estimation to investigate the perceptual components of signal detection theory

Several experiments suggest that the relation between detection, signal energy, and perceived tone intensity is very different from the relation between detection, signal energy, and perceived tone duration. We propose a new task, the magnitude estimation and detection (MED) task, that allows one to assess the relation between the psychological dimensions of a stimulus and detection. In Experiment 1, we used the MED task to assess the relation between perceived tone intensity and detection in a yes/no task. The data show a strong relation between the two. In Experiment 2, we used the MED task to assess the relation between perceived tone duration and detection in a yes/no task. The data show a relatively weak relation between the two. Our data suggest that tone intensity is a less perceptually noisy dimension than tone duration. We present the advantages and disadvantages of the MED task with the hope that this task can aid researchers in better understanding the perceptual and decisional mechanisms underlying various cognitive processes.     

The effects of collaboration and punishment on prospective memory performance in a group setting

Remembering to perform a delayed intention is termed prospective memory (PM). Often delayed intentions are shared by more than one person; however, there is a dearth of studies examining PM in social settings. We aimed to investigate whether the potential consequences of one's behavior across diverse group settings influence PM performance in event‐ and time‐based tasks. A total of 207 participants were randomly allocated to either an individual, collaborative, or collaborative plus penalty motivation condition and were tested in a 2‐ or 3‐person setting. For the time‐based PM task, participants responded less timely in the individual motivation condition, whereas there was no difference between the collaborative motivation conditions. No significant effects were found for motivation condition on the event‐based task or for group size on PM performance. Analyses of ongoing task performance revealed that participants' attention allocation policies change depending on how individuals prioritize the ongoing and PM tasks.     

Affirmative Dialectical Behavior Therapy Skills Training With Sexual Minority Veterans

Minority stress theory posits that unique stressors create an invalidating environment, which places sexual minority individuals at increased risk for psychiatric morbidity. Sexual minority veterans’ experience of minority stressors results in elevated levels of emotion dysregulation, anxiety, depression, and suicidality. Clinical interventions designed to address minority stress and treat emotional dysregulation and related disorders among sexual minority veterans are warranted. Professional guidelines recommend the adaptation of evidence-based treatments to address the unique features of sexual minority and veteran mental health. Dialectical Behavior Therapy (DBT) is a treatment for emotion dysregulation and related problems that addresses an invalidating environment, which is an appropriate framework for sexual minorities. The current research adapts the Emotion Regulation module of DBT Skills Training. This adaptation highlights minority stress as part of the invalidating environment and adds new teaching points to address the unique features of sexual minority mental health to create Affirmative DBT Skills Training. Six sexual minority veterans completed Affirmative DBT Skills Training meeting on a weekly basis for 10 consecutive weeks. Before and after treatment, participants completed measures of emotion regulation, anxiety, and depression as well as assessments of minority stress processes. Affirmative DBT Skills Training was well received in this sample. Results suggest that the intervention was effective in decreasing emotion dysregulation and symptoms of depression. These findings suggest Affirmative DBT Skills Training is a promising treatment, although more research is warranted, particularly given the small sample size and lack of a control group.
